Patent CH-615950-A5 (CH)
Title: Process for spinning a metal alloy and section obtained by this process
Inventor: BERCOVICI SERGE
IPC: C22F1/057
Filed: 1977-02-15
Abstract: A billet 100 mm in diameter with structural hardening, of the A-U4SG type, which has the following composition (in percentage by weight): Fe : 0.42, Si : 0.91, Cu : 4.24, Mn : 0.82, Mg : 0.51, Al: remainder, is subjected to a heat treatment consisting of being held at 605 DEG C for 15 minutes. This treatment has the effect of bringing a proportion of the alloy of approximately 13 % by weight into the liquid state and of causing an onset of change of the solid dendritic phase towards a globular form. Immediately after this heat treatment, this billet is spun in a 800-t spinning press whose container is preheated to 420-450 DEG C and the die is water-cooled, in the form of a section of rectangular cross-section of 40 x 3 mm, leaving the press at approximately 450 DEG C. This section is quenched with air as it leaves the die. After annealing for 8 hours at 175 DEG C, the section obtained has mechanical characteristics (elastic limit and breaking load) which are improved when compared with those of a section obtained by spinning under the same conditions, after the same heat treatment prior to the spinning, but without performing air-quenching on leaving the press.

Patent CH-650218-A5 (CH)
Inventor: HEIZ ULRICH DIPL-ING
IPC: B65G1/04
Filed: 1981-05-05
Abstract: A transfer apparatus wherein the conveyed loads, which need not absolutely possess a square or rectangular cross-sectional area or configuration, are received by or delivered from a transport vehicle, without the load itself having to experience a tilting movement, when it departs, for instance, from a stationary chain conveyor and is taken-over by the chain conveyor of a displacement carriage. The gap between the stationary chain conveyor and the chain conveyor mounted upon the transport vehicle is bridged by the laterally movable displacement carriage. The related chain drive serves for moving the conveyor chains of the chain conveyor and the displacement carriage. An alternately effective brake-locking device controls both movements. With blocked conveyor chains the displacement carriage, depending upon the direction of rotation of the drive motor of the chain drive, moves laterally in one or the other direction until reaching a related lateral stop or impact member. With released conveyor chains and blocked displacement carriage the conveyor chains of the chain conveyor are displaced until the conveyed load can be transferred or received, as the case may be.

Patent CH-628250-A5 (CH)
Title: Disposable filter
Inventor: HEIN WOLFGANG DR
IPC: B01D63/08
Filed: 1981-07-08
Abstract: In known disposable filters for filtration, in particular pressure filtration, in which a housing top and a housing bottom are each furnished with a flange, the filter element is inserted between the flanges by which the filter housing is sealed. As a result, the compressive strength of the disposable filter is impaired. In addition, engineering problems with regard to the positioning of the filter element occur in the production of the disposable filter. In order to achieve high compressive strength and simplified assembly, in the novel disposable filter, the housing top (1) and the housing bottom (2) each have an external flange (7 and 8 respectively), which both lie flat directly against each other, while the filter element (3) lies in a cup-like recess of the housing bottom (2) and is tightened by its outer edge by means of a downwardly drawn edge (10) of the housing top (1) penetrating telescopically into the housing bottom. The disposable filter is sealed by a closure ring (9) injection moulded around the flanges. <IMAGE>

Patent CH-623386-A5 (CH)
Title: Positive mechanism with a continuously variable transmission ratio
Inventor: GYGI WALTER
IPC: F16H23/08
Filed: 1979-09-01
Abstract: An input shaft (1) of the mechanism drives, via gearwheels (2, 3), a wobble plate (8) which pivots a driving disc (11), held fixed in terms of rotation in a housing (21), about a pivoting axis perpendicular to the axis of rotation of the wobble plate (8). A rack (12) is connected to a slider displaceable in a guide on the driving disc (11) and is moved backwards and forwards by means of this slider. The rack (12) is guided in another guide (15) and drives an intermediate shaft. This drives two first gearwheels (48, 58), which are mounted in a displaceable bearing block (27) and are brought into engagement cyclically with two gearwheels (49, 59) by a pivoting of the bearing block (27), with the result that the reciprocating motion of the rack (12) is converted into a unidirectional rotary motion of an output shaft (30). The bearing block (27) is pivoted by a rod (43) driven by a cam (5). The transmission ratio is varied by displacement of the further guide (15) with the rack (12) perpendicularly to the axis of the wobble plate, the slider being displaced in the first guide. This makes possible an inexpensive construction with a high transmission ratio and a high efficiency. <IMAGE>

Filed: 1989-12-22
Granted: 1992-04-28
Abstract: Le procédé est caractérisé par l'emploi d'au moins deux pompes à chaleur thermodynamiquement indépendantes, pour lesquelles les sources chaudes et froides des fluides externes communs aux deux pompes à chaleur sont partagés en autant de zones qu'il y a de pompes à chaleur. Suivant une variante préférentielle, l'utilisation d'au moins deux pompes à chaleur, de mélanges non azéotropiques, et d'échangeurs à toiles métalliques si les fluides externes sont des gaz, apporte une solution thermodynamiquement optimum, par une valorisation poussée de l'exergie de l'enthalpie récupérée à la source froide, et par une économie d'exergie de l'enthalpie transférée à la source chaude. Ce procédé convient particulièrement bien aux installations de séchage avec récupération de l'enthalpie de l'air extrait, comme à la récupération de l'enthalpie des fumées de combustion du gaz naturel; il permet d'obtenir un excellent coefficient de performance.

Title: Shuttle yarn tensioner - including two clamping plates magnetically biased together
IPC: D03J5/24
Filed: 1970-11-25
Granted: 1972-07-07
Abstract: The parallel clamping plates are pref. located between parallel flanges of a plastic mounting and each have an associated biasing magnet secured to its rear face. The polarity of the biasing magnets is such that they exert a frictional drag on yarn passing between them. A movable auxiliary magnet may be arranged adjacent each biasing magnet, the polarity of the auxiliary magnet being such as to repel the associated biasing magnet. Adjusting the separation between the auxiliary magnets and associated biasing magnets varies the biasing force on the clamping plates. The plates exert a uniform force on the yarn thereby reducing breakage of strands of multi-strand twisted yarns.
