Title: Rain-tight and fire-resistant movement profile system
Inventor: FIGEN ERDOGAN
IPC: E04B1/68
Filed: 1986-09-23
Granted: 1988-06-09
Abstract: Rain-tight and fire-resistant movement profile system for a freely movable connection of an old-building wall to an abutting annexed exterior wall, composed of three individual profiles, which are plugged one into the other and can move with respect to one another in each case, as well as of a screening profile and a folded plastic profile. The object of the invention is to construct an annexe in a free-standing manner in front of an old building without rigidly connecting the abutting annexed exterior walls to the old-building wall and without loading the old-building wall statically. In this arrangement, a freely movable connection profile, which is rain-tight and fire-resistant, is necessary. The movement profile system manufactured from steel sheets corresponds to these requirements and is composed of a U-shaped wall profile (1), of a U-shaped annexe profile (4) and of an L-shaped movement profile (15). The flanges of the profiles (1) and (4) serve to guide the legs of the freely mounted movement profile (15), the overlapping of the flanges with the legs constituting fire-resistant labyrinthine passages which prevent the penetration of flames. Static forces are neither absorbed nor transmitted by the movement profile system. It yields to settlement movements in every direction (Figure 1). <IMAGE>

Title: Method for electronic monitoring of the blower for a gas-heated glass ceramic cool-top platform, and device for implementing the method
Inventor: SUTTNER KARL
IPC: F24C3/12
Filed: 1986-11-06
Granted: 1988-02-11
Abstract: A method and a device for electronic monitoring of the blower for a gas-heated glass-ceramic cool-top platform consists of utilising the change in the A.C. voltage generated at the motor's commutator when a fault occurs to interrupt the gas supply to the cool-top platform. The amplified power-frequency voltage is fed to an A.C. window discriminator. As long as the A.C. voltage amplitude is at the triggering threshold which represents the centre of the discriminator's window, a square-wave signal is generated at the output, which is amplified and rectified and then causes the relay to pick up. When the blower motor current goes above or below the value specified with the window, an H or L signal is generated which causes the relay to drop out, thus cutting off the gas supply.

Title: Battery housing of plastics material - has lines of weakness ensuring break up in defined sections upon internal explosion of developed gas
IPC: H01M50/102
Filed: 1990-09-08
Granted: 1991-09-19
Abstract: A lead-acid battery housing (4) made from plastics material is constructed to rupture in a predetermined manner in the event of an internal gas/air explosion during  charging or service. The housing is moulded to provide a number of relatively wear lines of fracture (1) supported by a strong cagelike framework (3,6). An internal explosion thus results in immediate break-up of the housing (4) into defined sections (2) accompanied by rapid pressure release. All sections (2) are bent outwards but retained by the reinforcing action of the edge construction to reduce danger to personnel. USE/ADVANTAGE - For vehicle batteries. Considerably reduces danger to personnel from battery case fragments projected by accidental explosion as experienced with conventional construction. Little extra cost is involved since mutually self reinforcing edges and angles of individual cells inherently provide strong cage.
