Granted: 1989-02-09
Abstract: PCT No. PCT/SE85/00350 Sec. 371 Date May 15, 1986 Sec. 102(e) Date May 15, 1986 PCT Filed Sep. 16, 1985 PCT Pub. No. WO86/01882 PCT Pub. Date Mar. 27, 1986.This invention relates to a device for returning oil to at least one compressor (1) in a cooling or refrigerating system, in which the compressor sucks oil (16) from an oil collecting container (13) through at least one suction conduit (14) connected to the collecting container (13) and having one or more gas and oil intakes (15) which is or are situated above the oil level (16a) in the collecting container (13). To permit returning oil together with refrigerant and ensure a continuous oil supply to the compressor when in operation irrespectively of whether there are small or large oil amounts in the collecting container, the suction conduit (14) connects the gas and oil intake (15) to the inside (17) of the collecting container (13) above the oil level (16a) therein, and the gas and oil intake (15) has a substantially smaller throughflow area than the collecting container (13) to produce such a gas velocity in the gas and oil intake (15) that after the oil (16) collected in the collecting container (13) has been foamed up at the start of the compressors, the gas is capable of elevating the collected oil (16) on the inside of the collecting container (13) to the suction conduit gas and oil intake (15) and carrying it farther into the suction conduit (14) as the intake or intakes are connected to the inside (17) of the collecting container (13).

Abstract: An enclosed measuring device for measuring the relative position of two objects which are movable relative to each other includes a housing provided with a longitudinal slot. The slot is closed by means of cover members mounted in a chamber of the housing. The cover members are comb-shaped in transverse cross-section and are arranged so as to mesh with each other, resulting in a labyrinth-type line of contact between the cover members. A carrying member providing the connection between the interior of the housing and one of the objects has a meander-like shape conforming to the labyrinth-type line of contact between the two cover members, so that an effective sealing action is ensured even at the location where the carrying member extends through the cover members.

Abstract: A method for the manufacture of LSI complementary MOS field effect transistor circuits to increase the latch-up hardness of the n-channel and p-channel field effect transistors while retaining good transistor properties by incorporating a further epitaxial layer and highly doped implantation regions into a lower epitaxial layer from which the wells are generated by out-diffusion into the upper epitaxial layer. In addition to achieving optimum transistor properties, the reduced lateral diffusion provided enables a lower n+/p+ spacing, and thus achieves a higher packing density with improved latch-up hardness.

Abstract: A metering valve comprised of two rotary registers are each provided with cutouts which are symmetrical in relation to the axis of the central opening defined by the movement of the registers. In accordance with the present invention, a mechanism for operating the registers synchronously and in opposite directions is composed of levers and connecting rods acting on the axis of suspension and rotation of the registers through the action of, for example, hydraulic jacks. In order to avoid the offsetting of the flow because of the difference between the radii of curvature of the registers, one of the connecting rods acting on the axis of the registers is adjustable in length.

Abstract: A device changes the cut-in and cut-out positions of two groups of lock parts in a system (I or II) of a flat-bed knitting machine with an even number of systems. In each system, one group of lock parts selectable and actuable by the device is cut in and the other group is cut out, a group comprising at least one lock part. At the same time, all four mathematically possible combinations for the cut-ins and cut-outs can be set in two systems (I, II) in a system-independent manner. This is carried out by means of a common bolt (18) which is in engagement with the groups of lock parts (38, 40) capable of being cut in and cut out or with a connection part of the two groups and which is displaceable into four different positions (A, B, C, D). <IMAGE>
