Patent CH-587632-A5 (CH)
Title: Sturdy prestressed office table - has tie controlling table top central section to ensure lightweight construction
IPC: A47B13/02
Filed: 1975-07-11
Abstract: The office table ensures a steady and sturdy design which is not subject to vibrations without making either the top or the bottom support structure massive. This is achieved with the tension tie preload which allows a greater load capacity without excessive sag, and thus wood particle boards can be employed in the design. The top board is provided with a finishing layer and side reinforcement strips of wood or plastic. The ties (4) are set over the bottom edge of the strips and inserted into the angles (5) of the longitudinal beams (6) which are provided with holes for clamping screws of the board. The other end of the beams (6) are welded to traverses (8), which, in turn, are welded to table legs (9).

Title: Pneumatic feeder for coherent strands of fibre - threads through and pieces up rovings at high speed
IPC: B65H51/02
Filed: 1975-10-03
Abstract: A continuous, coherent strand of textile fibres is fed forward through a duct in which a flow of air aligned to the direction of the motion of the fibre is generated. The conveyor duct is formed by a tube the section of which is a multiple of that of the strand of fibres to be transported, and equipment is provided to set up a flow of air under suction. A number of tubes end in a chamber connected to a vacuum; the chamber having an outlet for the strands of fibres which are supported on driven cylinders, one of which has a permeable surface. The inner surface of the permeable drum is screened over a definite length and the pressure on the fibres is balanced out. The arrangement cuts out the loss of time involved in the manual transfer of strands, rovings, threads etc., from the point of availability to the inlet of the processing machine mext in line. This is esp. important in the case of a draw frame where the ends have to be threaded separately through rollers to the feeder. The piecing up of the end of a strand running out and the start of the next is partic. important with high speed machines in which the cans have to be changed at brief intervals.
Patent CH-634891-A5 (CH)
Title: Up-and-over door
IPC: E05D15/42
Filed: 1978-12-28
Abstract: The door leaf (1), which is guided at the top in run-back rails (2), is articulated at the bottom on supporting levers (5) which are pivotable about fixed pivot pins (4). A tension spring (8) acting counter to the weight-related door-leaf moment is fastened to an extension (6) of the supporting lever (5), the said extension leading beyond the pivot pin (4). This extension (6) is designed as a curved segment, over which runs a roller chain (7) which is fastened at one end to the curved segment and at the other end to the tension spring (8). The radial differences of the approximately parabolically curved surface are selected so that, during the pivoting of the supporting lever (5), the lever arm of the spring-tension moment changes continuously in such a way that the respective spring-tension moment is in equilibrium with the weight-related moment of the door leaf (1) in virtually every one of its tilting positions. Consequently, the door leaf (1) is stable in every position and the effort needed to tilt the door leaf is minimal. <IMAGE>

Filed: 1975-02-13
Abstract: Printing inks for the sublimation-transfer process, contg. (A) cationic dye(s), (B) soluble resin(s) as stabiliser, film-former and thickener, (C) a low viscosity org. solvent or solvent mixt. in which (A) is only slightly soluble and (B) is 5% soluble, (D) an (in)org. acid acceptor or mixt., and (E) an indicator dye inert to (D).

Allowance is made for the effect of the thermal cycle on the steel surface exposed to the welding heat. The annealing is carried out so that after the steel is heated to a transformation point A3 it is cooled in 5-50 seconds to 500 degrees C and subsequently, in 20-4300 seconds, slowly and continuously from 500 to 200 degrees C, at a speed corresponding with the thermal cycle in welding, so that a transformation of the steel from the austenite structure is brought about.
