Patent DE-4125115-A1 (DE)
Inventor: GALLE ALFRED
IPC: A47J27/00
Filed: 1991-07-30
Abstract: A method of manufacturing a cooking utensil comprising a round container for the food. The container comprises a container, a plate made of heat-conducting material and a cap enclosing the plate, the cap being made from a sheet-metal disk and having a base provided with a convex curvature towards the container and also having collar which bears against the round container in a curved transition region between the container base and the container jacket. The container and the cap are made of stainless steel. The plate is intermetallically bonded to the container base and the cap. The plate, the sheet-metal disk and the container base are centered and connected by a central spot weld, using electric resistance welding. Next, the intermetallic bond is produced by single or multiple impulse pressure and permanent deformation and the cap collar is formed on the sheet-metal disk and its rim is placed around the container. Use is made of a sheet-metal disk having an edge which, during the shaping of the cap collar, is permanently deformed and pressed against the container. The sheet-metal disk, the plate and the container base are centered by the resistance welding so as to be resistant to impulse pressure. The pulse pressure is exerted so as to produce the convex curvature in the cap bottom. During impulse pressure, the air is first expelled from the region between the sheet-metal disk and the cap collar in process of formation. During and after this process, a seal is produced in the form of permanent deformation with regard to the plastic deformation of the plate material.

IPC: E05G7/00
Filed: 1992-01-22
Abstract: The invention concerns a container with a time lock for safeguiding banknotes, the container providing access in a predetermined sequence to increasing amounts of money. Mounted in the container housing (1) is a lockable sliding drawer (2) divided, perpendicular to the direction of opening and closing (S), into n compartments (2.1, 2.2,..., 2.n) of depth (a1, a2,..., an). The container is fitted with a time-control device designed to release and push open the drawer (2). When released, the drawer (2) is pushed out of the housing (1) in a predetermined and adjustable sequence of movements, beginning by opening by a distance corresponding to the depth (a1) of the first compartment and continuing to open by the depth of each subsequent compartment. The drawer (2) remains open until pushed back into the closed position and locked in place in this position, and the release mechanism switched off.

Inventor: SCHRAUWEN HANS JOACHIM
IPC: B65H7/10
Filed: 1992-02-11
Abstract: In a web run control installation having a non-contact sensor (1) detecting the web edge of a running material web (3), which sensor can be adjusted by a sensor adjusting device, to be able to compensate in an easy way for any changing of the material to be controlled and/or for sensor soiling, the sensor adjusting device is actuated by an electronic signal processing device (4) for executing an adjusting movement transversely with respect to the web edge, the signal processing device (4) monitoring from the sensor (1) the signal changes occurring and deriving from the absence of a signal change during the adjusting movement a bright value (H) or dark value (D) and storing this value, whereupon an intermediate value (W) is calculated from this as the guide value for the web run control and is stored. Under given operating conditions, this program sequence is repeated, whereupon the intermediate value (W') thereby determined is compared with the originally fixed value and, if a difference occurs, a correction factor is calculated, by means of which the intermediate value (W') last fixed is corrected for assimilation to the originally fixed guide value (W).

Patent DE-4208227-A1 (DE)
Inventor: VOELKLE ROLF
IPC: A47C3/026
Filed: 1992-03-14
Abstract: In a chair, a seat-part support (11) and a backrest support (12), which is adjustable in inclination, are connected movably to effect a synchronous adjusting movement taking place relative to the frame (10). The backrest support engages at its lower end (12a) below the seat-part support and is connected to it for simultaneous movement by means of at least one connecting element. In a transfer movement initiated by the motion of the body of the chair-user, the backrest support is lowered while the seat-part support is simultaneously moved forwards and lowered at least in its rear part (11b). Due to the fact that the backrest support (12) and the seat-part support (11, 111, 211) transmit their movement onto the connecting means and onto one another at points on the connecting means which are spaced apart and are guided on the frame despite being bound to paths which are independent of one another, the backrest support being lowered at least slightly further than the seat-part support in the connection region to the seat-part support during the transfer into the rest position, a high-quality chair is produced in a cost-effective manner, which chair can be transferred into a rest position which is as comfortable as possible. <IMAGE>

Title: Bridge circuit for operation of brushless DC motor - includes potential-shifting capacitor as source of auxiliary voltage for turn-on of each MOSFET connected to positive supply
Inventor: KARWATH ARNO
IPC: H02P6/20
Filed: 1992-07-15
Abstract: The bridge circuit is formed entirely from n-channel MOSFETs (11,11',12,12'). For the switching of the transistors (11,11') connected to the positive DC supply (+Vcc) an auxiliary potential is produced by a shifting capacitor (13,13') of e.g. 2.2 microfarads connected between a +12V DC rail (17) and the emitter of the phototransistor in an opto-coupler (15,15') whose collector is linked to the gate electrode. The circuitry ensures that this auxiliary potential is built up before the rotor of the motor begins to move, and it is available at a definite level throughout longer standstill periods. ADVANTAGE - Reliable switching of power transistors connected to positive supply conductor is possible without any additional DC-DC converter or p-channel MOSFET voltage source.
