Abstract
Abstract A parallel construction, particularly for a top-loading balance with elecmagnetic force compensation, has two essentially identical, preferably trapezoidal, movable guides in parallel horizontal planes. The guides are mounted permanently at one end and connected together by a movable rigid connecting element at the other end. The two guides are displaced relative to one another in their planes at right angles to their axis of rotation.

Claim 1
Independent Claim
67 words
In a parallel construction for a top-loading balance having a housing, comprising two essentially identical movable guides in mutually parallel horizontal planes, said guides being mounted permanently at one end thereof and connected together by a movable rigid connecting element at the other end thereof, the improvement wherein said guides are displaced relative to one another in their planes at right angles to their axis of rotation.
Claim 2
Dependent Claim
67 words
In a parallel construction for a top-loading balance having a housing, comprising two essentially identical movable guides in mutually parallel horizontal planes, said guides being mounted permanently at one end thereof and connected together by a movable rigid connecting element at the other end thereof, the improvement wherein said guides are displaced relative to one another in their planes at right angles to their axis of rotation.
Claim 3
Dependent Claim
19 words
Parallel construction according to claim 1, wherein said two guides are provided with articulations in both end areas thereof.
Claim 4
Dependent Claim
17 words
Parallel construction according to claim 1, wherein said guides are made flexible for the entire length thereof.
Claim 5
Dependent Claim
91 words
Parallel construction according to claim 2, wherein the articulation of said upper guide located in the vicinity of the permanent mount, is displaced by a distance a+b relative to the corresponding articulation of said lower guide, wherein a is the distance between the central axis of said connecting element and the articulation in the vicinity of said connecting element for said upper guide and b is the distance between the articulation for said lower guide, located in the vicinity of said connecting element, and the central axis of said connecting element.
Claim 6
Dependent Claim
12 words
Parallel construction according to claim 1, wherein said guides are made triangular.

Dependent Claim
12 words
Parallel construction according to claim 1, wherein said guides are made trapezoidal.
Claim 8
Dependent Claim
24 words
Parallel construction according to claim 1, wherein the permanent mounts of both of said guides is formed on a portion of the balance housing.
Claim 9
Dependent Claim
30 words
Parallel construction according to claim 1, wherein the permanent mount is formed on a wall, at least one of said guides being mounted on the end surfaces of said wall.
Claim 10
Dependent Claim
27 words
Parallel construction according to claim 8, wherein slots, parallel to the ends of said wall, are provided for adjustment of the vertical distance between said two guides.
Claim 11
Dependent Claim
19 words
Parallel construction according to claim 9, further including an adjusting screw means for changing the width of said slot.
