Title: Air conditioning apparatus
Inventor: KIMURA TAKASHI
IPC: F25B49/02
Filed: 2016-03-08
Granted: 2021-07-08
Abstract: In an air conditioning apparatus 1, when the amounts of refrigerant oils 
retained in a first compressor 21al and a second compressor 21a2 are increased and oil 
5 levels in the first compressor 21al and the second compressor 21a2 reach a first oil 
outflow part 21a3 and a second oil outflow part 21a4, the refrigerant oils subsequently 
sucked into the first compressor 21al and the second compressor 21a2 flow out of the 
first oil outflow part 21a3 and the second oil outflow part 21a4 to a first oil outflow pipe 
48al and a second oil outflow pipe 48a2, and flow from the first oil outflow pipe 48al 
10 and the second oil outflow pipe 48a2 to a refrigerant outflow pipe 42a. The refrigerant 
oils flowing in the refrigerant outflow pipe 42a from the first compressor 21al and the 
second compressor 21a2 through the first oil outflow pipe 48al and the second oil 
outflow pipe 48a2 flow out of an outdoor unit 2a through a four-way valve 23a, and 
circulate through a refrigerant circuit 100 together with refrigerants.

Title: Process and apparatus for flotation, in particular for waste water purification
Inventor: WESCHKE JUERGEN DIPL-ING
IPC: B03D1/02
Filed: 1987-03-12
Granted: 1988-08-18
Abstract: Process and apparatus for flotation, in particular for waste water (effluent) purification, in which a frother is introduced into the pulp to be treated and the flotation pulp thus produced is forced into an essentially vertically running stream within a flotation cell. In the lower region of the flotation cell, finely dispersed small gas bubbles are generated by compressed air feed into this stream, to which gas bubbles some of the solid constituents of the flotation pulp to be floated adhere and are carried by the stream to the surface of the pulp. The froth can be removed there. The pulp to be treated is divided in this case into two flow paths, of which only a part-stream is provided with the frother and is exposed to the gas bubble formation, while the second part-stream is only fed to the first part-stream when a uniform gas bubble distribution and a uniform flow profile are achieved therein. This process and the corresponding apparatus make it possible, because of the high concentration of the frother in the flotation pulp, to achieve very small gas bubbles which also remain stable over a significant flow section. Despite this, only an environmentally acceptable frother concentration is present in the subequent purified water, without the purifying action of the flotation being impaired. <IMAGE>
Patent DE-3810132-C1 (DE)
Inventor: ARBTER CONRAD
IPC: B65G15/14
Filed: 1988-03-25
Granted: 1989-09-28
Abstract: The feed device for a belt conveyor ensures, in a technically simple manner, uniform frictional engagement between belt conveyor and workpiece along the feed device. The feed device comprises a retaining strip (10) open at the bottom, one or more pressure hoses (14) with air supply and exhaust, and a strip-shaped pressure-transmitting member (13) in contact with the belt conveyor (6). When the air is evacuated from the pressure hose (14), the contact pressure on the belt conveyor (6), and hence the conveying action of the latter, is discontinued. The feed device is particularly suited for conveying workpieces to sewing aggregates and folding and packaging machines.

Title: Variable transmission with V-belt - incorporates hydraulic system for controlling setting of conical pulleys
IPC: F16H61/662
Filed: 1990-12-13
Granted: 1992-01-16
Abstract: The cone pulley transmission applies axial force to an interposed belt etc. via hydraulic tensioners which are mounted on shafts to act on the axially adjusting pulleys. The tensioners are loaded via line-fed pressure medium by a pump from tank through a control valve. A torque sensor in the valve return chokes this to set the basic system pressure. A speed sensor on the drive shaft upstream of the transmission feeds medium as a function of speed onto a control element which together with a transmission power adjuster acts on the valve. An electrical switch valve (54) in the medium line (18,19) between valve (12) and drive-side tensioners (9,11) blocks off flow to this drive side tensioners when flow switches and connects the drive-side tensioners to offtake (26). The switch valve can only be switched provided that three in-series switches (58-60) are closed. The first switch (58) closes at minimum drive torque, the second (59) closes when the transmission is at a running radius on the drive side higher than the minimum running radius of the belt (8). The third switch (60) closes when the driving speed on the transmission side falls below a minimum value. USE/ADVANTAGE - Motor vehicles. Transmission can be switched over for starting from any position using control valve and series switches.

Title: Electrical feed line device to a steering wheel of a motor vehicle
Inventor: BECHTLE ROLF
IPC: H01R35/02
Filed: 1993-07-09
Granted: 1994-10-27
Abstract: The invention relates to an electrical feed line device to a steering wheel of a motor vehicle. The feedline device consists of an electrical conductor strip which is arranged in concentric windings in a housing, one end of the conductor strip ending at a core which is fastened around a steering spindle on the steering wheel, and the other end ending at a lower housing part which is held on the vehicle structure. A locking device prevents the core and the lower housing part from rotating. According to the invention, the feedline device is now provided with a locking device which acts in the radial direction in respect of the steering spindle. It is proposed in particular that the locking device be designed as a sheet-metal strip and in addition, that it can engage radially from the outside in recesses on the lower housing part. As a result of the arrangement of a plurality of recesses on the lower housing part, the feedline device can be locked in any rotation position. Finally, a second projection on the locking device, in conjunction with a ramp which is arranged on the steering wheel, forms a particularly simple and effective unlocking device.

Title: Device for measuring the length of a link-chain
Inventor: THALHAMMER ROBERT
IPC: G01D5/245
Filed: 1993-11-18
Granted: 1995-01-12
Abstract: It has been customary to date to measure the length of a link-chain, e.g. for a yacht anchor, by measuring rotational speed at a sprocket wheel (sprocket, chain wheel). According to the invention, the chain is guided by a sensor which uses a radio-frequency (high-frequency) electric field to detect the individual links and outputs corresponding counting pulses to an evaluation device which converts the counting pulses into a measure of length. It is thereby possible, for example, to run out an anchor chain in a simple way precisely to a specific depth and thereafter to recover it. <IMAGE>
