Abstract: Dans une piece formee d'une face exterieure du col (15) et d'une partie inseree (1), on forme une zone de flexion presentant deux plis (I, II); ces deux plis reunis par des coutures (16, 17). La formation des plis est facilitee par la presence de la partie inseree (1); dans la zone de flexion, la partie inseree (1) qui est generalement collee a la face exterieure du col (15), presente des bandes non renforcees (6, 7) dans la zone des plis (I, II) et une bande pour la flexion. Les bandes (6, 8) peuvent egalement etre remplacees par des incisions ou des perforations. La piece formee de cette maniere peut etre cousue, retournee et piquee avec la partie inferieure du col (20) comme un col d'une piece. Malgre l'apparence de plus grands frais de travail et de materiel par rapport a un col d'une piece, le col deux pieces presente un label de qualite pour la piece de vetement.

Abstract: An electrically controlled hydraulic remote controller (10) for use in piloting the operation of a hydraulic control valve (11) comprising a pair of electrically operated three-way pressure control valves (15,16). Each control valve (15, 16) has a supply pressure inlet (17, 18) and a controlled pressure outlet (19,20) operable in the de-energized position to prevent flow from the supply inlet (17, 18) to said controlled pressure outlet (19, 20) and connect (via 21, 22, 23) said outlet (19, 20) to tank pressure. Each valve (15,16)when energized is operable to permit fluid flow from the inlet (17, 18) to the controlled pressure outlet (19, 20) in proportion to the solenoid (37,38) force operating said valve (15 or 16) and simultaneously permit fluid to flow to tank pressure. The controller (10) is responsive to the higher of the controlled pressure of the outlets (19 or 20) of the two pressure controlled valves (15, 16) for applying the higher controlled pressure (as in 20a) to the valve (f.i. 15a) having the lower controlled pressure to operate the valve (f.i. 15a) in direction increasing the passage (G) of fluid through the other valve (f.i. 15a) to tank.

Abstract: In a scroll type fluid compressor having an orbiting scroll member (14) and a fixed scroll member which forms at least one pair of outer fluid pockets and a center pocket therebetween for fluid compression, the axial end surfaces of each spiral element of the scroll members have a groove (21) along the spiral curve. At least one closed portion (211) is located along the groove (21) to block fluid flow in the groove. A seal element (22) is loosely fitted in the groove (21). During operation the compressed fluid flows into the groove (21) to urge the seal element (22) against the end plate (142, 132) of the opposite scroll member (14,13) so that the axial sealing between the spiral element and the end plate is assured without leakage of fluid along the groove. 
     Also, the closed portion (211) is located along the spiral element at the location where the line contact point where the outer fluid pockets and the central pockets merge to prevent back pressure changes from causing excessive wear of the seal element (22).

Abstract: A photothermal measurement cell for study of light absorption by a sample substance. The sample substance (5) is placed in contact with a temperature expansion element (6) of a solid material, for example quartz, glass, sapphire or the equivalent. The said element is arranged in contact with a mechanoelectric or mechanooptical transducer (7), for example a piezoelectric crystal. As the light is absorbed by the sample substance its temperature is raised, whereupon the temperature expansion element (6) expands and its mechanical motion is transformed to an electric signal by the transducer (7), whereupon the signal is amplified and registered for example by an X-Y recorder (10).

Abstract: A reusable electrophotographic element comprising a photoconductive layer containing sensitized zinc oxide particles and first and second binding agents that are incompatible. 
     The first binding agent has a higher affinity to zinc oxide than the second binding agent, is largely deposited on the zinc oxide, is a macromolecular compound having an average molecular weight of at least 12,000 and is present in the photoconductive layer in an amount of 1.5 to 9% by weight calculated on the zinc oxide. The quantity of the second binding agent in the photoconductive layer is larger than that of the first binding agent, said layer being built up from agglomerates of zinc oxide particles being substantially enveloped with the first binding agent, which agglomerates have a diameter between 2.5 and 6 µm and are sticked together by means of the second binding agent to form a porous layer having a negative charge density of at most 1m Coulomb per m 2 . The electrophotographic element has a very high resistance to both electrical and mechanical influences.
