Patent DE-4314472-A1 (DE)
Inventor: JONEN PETER
IPC: B21B29/00
Filed: 1993-05-03
Abstract: A bending block for bending the rolls (5, 6) of multiroll rolling stands. On both sides of the chocks (9, 10) of the pair of rolls (5, 6) to be bent, the bending block (7, 8) is rigidly connected to the window crossbeams (1 and 2) of the rolling stand. In each of the bending blocks (7, 8), pairs of partial bending jaws (11a, 11b; 12a, 12b; 13a, 13b; 14a, 14b) are guided so as to be displaceable in the directions of bending and are driveable by means of piston-cylinder units. The pairs of partial bending jaws (11a, 11b; 12a, 12b; 13a, 13b; 14a, 14b) act by means of pressure bearing surfaces on pressure-accepting surfaces on the chocks (9, 10), each of these pressure-accepting surfaces being assigned to one direction of bending. Each pair of bending jaws consists of partial bending jaws which can be driven independently in opposite directions and the pressure bearing surfaces of which are each assigned to one direction of bending. <IMAGE>

Title: Rotary heat exchanger
IPC: F24F3/147
Filed: 1993-05-28
Abstract: A rotary heat exchanger has a frame (2) and a rotating member (3), which is mounted rotatably in the frame (2) and whose end face (6, 7) has an inflow sector (6) and an outflow sector (7) which are traversed by the rotating member (3) during a revolution.

Title: Vehicle door hinge with pre-determined friction characteristic
Inventor: KUEHL HANS
IPC: E05D11/08
Filed: 1994-03-02
Abstract: The hinge has a pin (3) with at least one circumferential and radially rising wedge surface (4,4').

Title: Process and reactor assembly for incineration of de-watered industrial sludge
Inventor: BIERBAUM KLAUS DR
IPC: F23G5/00
Filed: 1994-07-15
Abstract: De-watered sludge is incinerated in a fluid bed reactor together with brown coal. Combustion gases and fluid bed particles pass through a separator which removes particles which are then returned to the reactor through a pipe. The novelty is that the wt. of the sludge is mechanically reduced by dewatering to 70-75% original wt. and that it is mixed with brown coal in ratio 0.2:1 and 1:1. This mixt. is introduced to the reactor at a point between the insertion point for pure brown coal and the point at which the sepd. incinerated particles and fluid bed particles are returned to the reactor and are exposed to reactor treatment at atmos. pressure between 750-850  deg C with supplementary oxygen gas.
Patent DE-4431791-A1 (DE)
Title: Signal selection device
Inventor: HORI TOSHIHIKO
IPC: G11C19/00
Filed: 1994-09-06
Abstract: In a signal selection device, a mode determining section 61 has a shift register 11, a clock production section 20 and a decoder 51. The clock production section 20 receives a mode signal M and produces a clock signal CK1, which is used to decode the mode signal M, from a system clock SYS. The shift register 11 receives the mode signal M and the clock signal CK1, and emits signals Q0 to Q3. The decoder 51 receives the output from the shift register 11 and emits the control signals S00 to S03. In consequence, only one connection is required in order to receive the mode signal M, and no connection in order to receive a clock. <IMAGE>

Inventor: KIBLAWI DANIEL F
IPC: F28F9/04
Filed: 1994-09-13
Abstract: A quick connect coupling (20) for securing a pair of air conditioning refrigerant lines (14, 16) to a system component (10) of an automotive air conditioning system is capable of being operated with one hand so as to allow both refrigerant lines (14, 16) to be simultaneously connected or disconnected from the system component (10). The coupling (20) includes a plate pivotable to radially engage the lines (14, 16) with apertures (38, 40), at least one of which having a restricted entry to pass over only a reduced diameter part of the line, distanced from the component (10). This constitutes a safety feature which prevents the refrigerant lines (14, 16) from being disengaged from the coupling (20) unless the coupling (20) is sufficiently loosened from the component (10) to allow the coupling 20 to be rotated out of engagement with one or both refrigerant lines (14, 16). <IMAGE>
