Inventor: KNIGHT LINDSAY CHARLES
IPC: F41J7/00
Filed: 1978-12-08
Abstract: In each case a pair of running wheels (5) and in each case a pair of drive wheels (4) are arranged protected by a housing (6) in the front and rear area. The running wheels are intended to roll on an upper tube (3) of the single-rail track (2). The drive wheels (4) roll on a lower tube (3') of the single-rail track. The main weight of the push-car (1) is supported on the lower tube by means of the drive wheels. The running wheels prevent the push-car tipping over and, for this purpose, are inclined with respect to a horizontal plane in such a way that their upper circumferential parts rest against the upper tube. The drive wheels (4) are inclined with respect to the vertical in such a way that their lower circumferential parts rest on the lower tube. Each of the drive wheels is provided with a hydraulic motor connected to it. In order to reduce slip between the drive wheels and the lower tube, the circumferential faces of the drive wheels are provided with a layer of polyurethane. By means of the above described arrangement of the running wheels and the drive wheels, the push-car is given an extraordinary stability against lateral loads, and good track holding. The push-car is therefore particularly suitable for carrying targets of large surface area and which are to be moved on a target range. <IMAGE>

Title: Switching mechanism with double contact blades - has contact positions controlled for easier release after welding due to arcing
Inventor: BERNET HERBERT
IPC: H01H1/36
Filed: 1980-03-19
Abstract: The arrangement of switching contacts with a protective fuse (11) reduces the welding action between the contact surfaces. Two pairs of bridging contacts (6,7) are mounted on a slider (5) for connection to L-shaped fixed contacts (3,4) and two other fixed contacts (8,9) opposite them, the latter connected to the fuse. This brings the fixed and moving contacts to four connecting and separating zones (12-15). One of the fixed contact blades (3) is shorter than the others so that contact is first made with it. The double blades form a pair and are mounted on the slider (5) for rotation, the slider carrying stops positioned each side of the blades giving different limiting positions, so that any welding caused by arcing is easily broken.

Patent DE-3026312-A1 (DE)
Inventor: BAUMGARTNER KARL
IPC: A47J27/16
Filed: 1980-07-11
Abstract: The pressure-cooker has a cooking container (16) which can be closed pressure-tightly by a lid (2) and is surrounded by a steam compartment (20) in order to heat it. To produce the steam in the steam compartment (20), a water bath (21) is arranged below it which is heated by heating elements (23). The bottom region (31) of the cooking container (16) is connected to the steam compartment (20) via a pipe (28). Inserted in the pipe (28) are a magnetic valve (29) to control the flow of steam in the pipe (28) and, near to the mouth (33) of the pipe (28) in the cooking container (16), a non-return valve (30) to prevent soiling of the pipe (28) and of the steam compartment (20) by the product to be cooked. When the steam pressure has reached a particular value in the steam compartment (20), steam flows out of the steam compartment (20) into the cooking container (16) with the magnetic valve (29) open and causes steaming of the product to be cooked there. A pressure-cooker which is known per se with steam heating of its cooking container can thus also be used for rapid cooking of food by means of steam by installing only a few additional components. <IMAGE>
