Abstract
Abstract A degausser has a housing having two housing sections of generally tubular configurations. A support element is accommodated in the interior of the housing, and has a tubular portion and a generally flat portion. A core of an electromagnet is accommodated in the tubular portion of the support element, and a coil of the electromagnet surrounds a part of the tubular portion in the housing. The flat portion is formed with resiliently yieldable projections which engage associated recesses at the housing sections with snap action so as to connect the housing sections to the support element. Electric leads pass through an opening of one of the sections, are received in slots of the flat portion in a labyrinthine manner, and connected to a switch supported on the support element and having an actuating element passing through a slot in the housing to the exterior of the latter. The housing and the support element are of synthetic plastic material.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
270 words
A degausser for degaussing magnetized components, comprising an elongated hollow housing having an internal surface and subdivided at a plane transverse to the elongation thereof into two discrete housing sections having respective detent recesses; a support having a plurality of elastically yieldable support portions which contact said internal surface of said housing to thereby position and support said housing sections on said support element, and of elastically yieldable detent projections which engage with snap action in said detent recesses of said housing sections to thereby connect the latter to said support element, said support element including a flat portion, and a tubular portion of magnetically permeable material, which are rigid with one another and extend longitudinally of said housing, said flat portion and one part of said tubular portion being accommodated in said housing, and another part of said tubular portion extending to the exterior of and longitudinally beyond said housing for juxtaposition with a component to be degaussed; and means for generating a magnetic field in the circumambient region of said other part of said tubular portion to degauss the component upon juxtaposition of said other part therewith, including a core received in and surrounded by said tubular portion of said support element and extending within said parts thereof, a coil convoluted at least around a region of said one part of said tubular portion of said support element, and means for supplying electric current to said coil so as to generate an electromagnetic field which penetrates through said tubular portion of said support element and acts on the component juxtaposed with said other part of said tubular portion.
Claim 2
Dependent Claim
270 words
A degausser for degaussing magnetized components, comprising an elongated hollow housing having an internal surface and subdivided at a plane transverse to the elongation thereof into two discrete housing sections having respective detent recesses; a support having a plurality of elastically yieldable support portions which contact said internal surface of said housing to thereby position and support said housing sections on said support element, and of elastically yieldable detent projections which engage with snap action in said detent recesses of said housing sections to thereby connect the latter to said support element, said support element including a flat portion, and a tubular portion of magnetically permeable material, which are rigid with one another and extend longitudinally of said housing, said flat portion and one part of said tubular portion being accommodated in said housing, and another part of said tubular portion extending to the exterior of and longitudinally beyond said housing for juxtaposition with a component to be degaussed; and means for generating a magnetic field in the circumambient region of said other part of said tubular portion to degauss the component upon juxtaposition of said other part therewith, including a core received in and surrounded by said tubular portion of said support element and extending within said parts thereof, a coil convoluted at least around a region of said one part of said tubular portion of said support element, and means for supplying electric current to said coil so as to generate an electromagnetic field which penetrates through said tubular portion of said support element and acts on the component juxtaposed with said other part of said tubular portion.
Claim 3
Dependent Claim
38 words
A degausser as defined in claim 1, wherein said means for supplying current to said electromagnet, includes electric leads; and wherein one of said housing sections is provided with an opening for passage of said electric leads therethrough.
Claim 4
Dependent Claim
26 words
A degausser as defined in claim 2, wherein said supplying means includes a switch interposed between at least one of said electric leads and said coil.
Claim 5
Dependent Claim

A degausser as defined in claim 3, wherein said switch includes an actuating element; wherein said switch is accommodated in said housing; and wherein at least one of said housing sections is formed with an elongated slot in which said actuating element is received for movement longitudinally of said slot, and through which it extends to the exterior of said housing.
Claim 6
Dependent Claim
16 words
A degausser as defined in claim 4, wherein said switch is connected to said support element.
Claim 7
Dependent Claim
38 words
A degausser as defined in claim 2, wherein said support element includes at least two slots; and wherein said electric leads pass through said slots in a labyrinthine manner so as to be connected to said support element.
Claim 8
Dependent Claim
19 words
A degausser as defined in claim 1, and wherein said support element includes connecting portions having said detent projections.
Claim 9
Dependent Claim
17 words

Claim 11
Dependent Claim
17 words
A degausser as defined in claim 1, wherein said support element is of a synthetic plastic material.
Claim 12
Dependent Claim
18 words
A degausser as defined in claim 1, wherein said support element is entirely of an elastically yieldable material.
Claim 13
Dependent Claim
37 words
A degausser as defined in claim 1, wherein said housing has a longitudinal axis; and further comprising means for preventing rotation of one of said housing sections relative to the other housing section about said longitudinal axis.
Claim 14
Dependent Claim
36 words
A degausser as defined in claim 12, wherein said preventing means includes a recess on one of said housing sections at said plane, and a projection on the other housing section in engagement with said recess.
