Inventor: DE LORENZO BRUCE
IPC: F16K15/14
Filed: 1980-01-04
Abstract: In one use the valve (10) positively seals a line through which fluid flows against reverse or backflow of the fluids in any position in which the valve (10) is disposed. In another use the valve mechanism (30) functions as a vacuum breaker. In still another use it functions as a foot valve (50). The same valve structure is utilised in all of the aforesaid functions. Generally, the valve structure has a housing comprising an inlet member (15) and an outlet member (17) which are joined together. A flexible diaphragm (19) is secured between the inlet and outlet members (15) and (17). One end of the inlet member (15) is provided with a shoulder or flange passage (16) adjacent the flexible diaphragm (19). One end of the outlet member (17) is provided with a valve support seat (18) adjacent the flexible diaphragm (19). The flexible diaphragm (19) has apertures or orifices (20) interiorly of its perimeter and a solid central portion. Under pressures exerted from the inlet side or the outlet side the diaphragm (19) flexes from a position wherein its central portion abuts the valve support seat (18) and the orifices (20) are exposed for the flow of liquids to the outlet side to a position wherein the orifices (20) are in proximity to the shoulder or flange passage (16) and the central portion of the diaphragm (19) seals the passage (16) from the inlet member (15).

Abstract: A control system is adapted to operate a fluid load (11) by putput of a variable delivery pump (10) having a control cylinder (12) governed by flow and pressure responsive means for regulating the displacement of the pump (10). A flow control valve (13) has input and output ports (16, 17) connected respectively to the pump (10) and load (11) and by co-operation of a spool (33), subject at one end to pump pressure via pilot passage (44) and at the other end to a biasing force provided by a spring (34), with orifices (42, 43) provides a pump discharge flow that is inversely proportional to pump discharge pressure. A load sense control valve (14) has a spring biased spool (48) subject at one end to load pressure over a first pilot line (24) and subject at its other end to pump pressure over a second pilot line (23). A land (55) on the spool (48) determines the connection of the control cylinder (12) either to pump pressure at port (53) for regulating the delivery of the pump or to atmosphere at port (56) for relieving the regulation. By this means the pump displacement is adjusted to maintain substantially constant horsepower output under variable load conditions whereby the load (11) can utilize substantially constant horsepower approaching a prime mover input torque curve without requiring mechanical feedback indicative of the displacement of the pump (10).

Abstract: According to the invention, the method of making round objects (1), for example wheel rims for motor vehicles, is organised in such a way and the equipment is chosen such that an extruded part with overlength, i.e. with an allowance, is used, as the developing of the rim would require, and these pieces which deform and absorb stresses are chosen by appropriate choice of the method steps and equipment such that they are located at the beginning and end of the extruded part and can then be cut to length after the corresponding method steps. Thus, in the first two method steps a core mould (2) is used, around which the extruded part is bent, whereas in the following step rolling is carried out, i.e. a device which is suitable for rolling operations is used. The procedure during welding of the transverse joint is also designed to avoid stresses, by clamping in a certain sequence. <IMAGE>

Abstract: Dispositif de mesure precise de dimensions associees a un objet eloigne sans etre en contact avec l'objet lui-meme. Un rayon de lumiere (12B) est dirige sur une surface de l'objet (8) et une partie reflechie du rayon est detectee par un element de photodetecteur (12E). La dimension particuliere de l'objet est determinee mathematiquement en mesurant la distance (d) de decalage du signal lumineux reflechi par rapport a un point predetermine sur le photo-detecteur qui est aligne avec un plan de reference (10c) de l'objet. En utilisant deux tetes et des rayons lumineux et des photo-detecteurs respectifs, l'epaisseur d'un objet eloigne peut egalement etre mesuree. De maniere a compenser la relation angulaire entre la surface de l'objet et celle du photo-detecteur, un circuit de calibrage de linearisation (54) permet d'enregistrer des corrections pre-etablies dans des unites de memoire programmables. Les valeurs de calibrage sont determinees au cours de la fabrication et sont correctes pour chaque lecture normalement non lineaire pour des distances croissantes dans une plage de mesure predeterminee. On augmente encore la precision du systeme en utilisant un circuit d'echantillonnage a haute frequence (30, 32) pour moduler la source lumineuse, avec un circuit de demodulation (44) servant a faire la distinction entre le rayon lumineux d'entree et des signaux lumineux ambiants etrangers.
