Abstract
Abstract Autoclavable power-pak having a bore in a stainless steel casing housing a lens-end light bulb with an externally threaded base, a heat and pressure resistant silicone rubber seal comprising a tubular body surrounding the bulb and an integral annular flange extending inwardly from its upper end for resilient engagement with the lens end of the bulb to effect a sealing action, and a brass sleeve threadedly mounted on the base of the bulb to effect a sealing action, and a brass sleeve threadedly mounted on the base of the bulb and having a lower outwardly extending flange engaging the case for electric current transfer purposes and the lower end of the tubular body to effect a second sealing action between the bulb and the casing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
56 words
In an autoclavable power-pak having a bore in a casing member housing a lens-end light bulb, a heat and pressure resistant seal interposed between said bore and said bulb, comprising a tubular body surrounding said bulb, and an integral annular flange extending inwardly from the upper end of said body for sealing contact with said bulb.
Claim 2
Dependent Claim
56 words
In an autoclavable power-pak having a bore in a casing member housing a lens-end light bulb, a heat and pressure resistant seal interposed between said bore and said bulb, comprising a tubular body surrounding said bulb, and an integral annular flange extending inwardly from the upper end of said body for sealing contact with said bulb.
Claim 3
Dependent Claim
32 words
In an autoclavable power-pak according to claim 1, wherein said bore defines an annular shoulder, means for exerting pressure longitudinally on said seal to engage the upper end thereof with said shouldEr.
Claim 4
Dependent Claim
34 words
An autoclavable power-pak according to claim 2, wherein said pressure-exerting means comprises a sleeve interposed between said bulb and said seal having an outwardly extending flange engaging the lower end of said tubular body.
Claim 5
Dependent Claim
33 words
In an autoclavable power-pak according to claim 3, wherein said casing member is separably attachable to a second casing member held against said outwardly extending flange and constituting part of said pressure-exerting means.
Claim 6
Dependent Claim
43 words
An autoclavable power-pak according to claim 4, wherein said bulb has an externally threaded base, and said sleeve is a metallic conductor threaded thereon with said outwardly extending flange held in contacting engagement with said first casing member by said second casing member.
Claim 7
Dependent Claim
34 words
An autoclavable power-pak according to claim 1, wherein said seal is of silicone rubber and said annular flange is in resilient engagement with the lens end of said bulb to effect a sealing action.
Claim 8
Dependent Claim
52 words
In an autoclavable power-pak according to claim 1, wherein said annular flange is in resilient engagement with the lens end of said bulb to effect a sealing action, means for exerting pressure against the lower end of said body to effect a second sealing action between said bulb and said casing member.
Claim 9
Dependent Claim
44 words
An autoclavable power-pak according to claim 7, wherein said bulb has an externally threaded base and said pressure exerting means comprises an electrically conductive sleeve threaded thereon with an outwardly extending flange at its lower end engaging the lower end of said tubular body.
Claim 10
Dependent Claim
31 words
An autoclavable power-pak according to claim 8, wherein said pressure exerting means also includes means for holding said outwardly extending flange on said sleeve in electrical-contacting engagement with said casing member.
