Title: Refrigeration circuit with rotary piston compressor - has oil separator connected to compressor outlet
Inventor: SCHMITZER WILLI
IPC: F01K25/08
Filed: 1990-03-16
Abstract: The main patent concerns a refrigeration circuit which employs a rotary piston compressor. The oil used for lubricating the compressor bearings is also used for sealing the rotors so that there is no direct contact between them. The lubricating oil is separated from the liquefied refrigerant in the evaporator. In this addition to the patent, an oil separator (3) is connected to the compressor outlet (2). The separated oil is then returned to the compressor bearings. The  refrigerant leaving the separator (3) flows to a receiver (10) and then to the pump (5) and evaporator (1). USE - Refrigeration circuits using rotary piston compressors.

Title: Drive using repelling power of short circuit - has open current line arranged behind short circuits
Inventor: TWELENKAMP JOACHIM
IPC: F03H1/00
Filed: 1990-04-30
Abstract: The material at the carriage rear is current repelling and fireproof. The radiation surface at the carriage rear side consists of wire and is as large as possible. With a timer to give a slow starting phase, the short circuits are increased to give up to 10,000 current shocks per second. If using a plug box and not a generating set, a fuse must automatically be switched in circuit. The carriage is then moved forward. The external propagation wave of the current discharge has the most power and it must be repeated as many times as possible. Bar magnets can be used for stopping or reducing gravity. USE/ADVANTAGE - Short circuit propulsion. With sufficient radiation surface iron does not melt with short circuit and metals with high melting point can be used.

Title: Welding together polyurethane sheets - using appts. to overlap adjacent edges of two sheets, hold them in position, pass radiant over the edges and press them together
Inventor: HAASE GERHARD
IPC: B29C65/14
Filed: 1991-02-28
Abstract: Two sheets of polyurethane are bonded together along their sides by heating them to m.pt. and pressing them together. They are overlapped along the join area, the overlap is briefly lifte dup from beneath and continuously, the raised edges are heated to just below the m.pt. and then raised to m.pt. the edges are replaced in the original plane of the sheets and the heated strips are pressed together. Two pairs of wheels allow the appts. to run over the sheets, these wheels are however slightly tilted so as to bring the edge sinto overlap.

Title: Automatic ring frame doffer - has controller with sensors on individual grippers which can either interrupt doffing cycle for whole machine or only stop individual spinning positions
Inventor: WIESE FRANZ JOSEF
IPC: D01H9/00
Filed: 1991-09-27
Abstract: A ring spinning or twisting machine has equipment for changing bobbins as a group with sensing devices on individual spinning positions. A fault signal (23) on an individual gripper (7) either stops the doffing procedure or only stops the partic. spinning position which gave rise to the fault signal (23). A fault signal (23) which occurs after removal of the full bobbins (11) from the spindles (4) or after placing them on a transport device (9) stops the doffing procedure. A fault signal which occurs after removal of the empty tubes (12) from the pegs (10) of the transport device (9) or after placing them on the spindles (4) only stops the appropriate spindle. A bobbin changing device (5) removes full bobbins (11) from the spindles, puts them on a transport device (9) and replaces them with empty bobbins (12) taken from pegs (10). Each gripper (7) has a sensor (15) to signal the presence or absence of a full/empty bobbin. The sensors are connected to a controller (16) which is also linked to a light beam sensor (29,30,31) and roving stops. Several stages of fault detection are possible to deal with malfunctions of the gripper mechanisms at various stages of the doffing cycle. USE/ADVANTAGE - The invention reduces the amt. of time during which the whole machine is stopped due to an individual fault.
