Patent DE-4205911-A1 (DE)
Inventor: MOCK MARKUS
IPC: G08C19/28
Filed: 1992-02-26
Abstract: A device for monitoring the air pressure in pneumatic tyres comprises a transmitting device fitted to each wheel of a vehicle and rotating with it, and a receiver which is built into the vehicle or accommodated in a separate housing. The transmitting device mounted in the wheel comprises a pressure gauge for measuring the tyre pressure, a transmitter and a signal generator which generates an identification signal unique to each transmitter and transmitted before or after the pressure signal. The receiver processes received signals only when the identification signal received matches a reference identification signal stored in the receiver. This facilitates reliable operation of the monitoring device and prevents false alarms.

Patent DE-4212567-A1 (DE)
Inventor: SCHMID DIETER C DIPL ING
IPC: C25D7/06
Filed: 1992-04-15
Abstract: An electroplating device (11) has a conveying system (19) which passes the printed-circuit boards on a horizontal through path through the treatment chamber (13). They are contacted by pincer-like gripping devices (32) which run in front of the front edge (63) of the printed-circuit board and in this zone grip it from above and from below. The gripping devices (32) are fastened to transverse beams (29) which on both sides are guided by chains (26) and are contacted electrically by contact bars (39). The printed-circuit boards (12) are thus dragged in a horizontal, centric track and are contacted at the same time. Alternatively, the printed-circuit boards (12) can be conveyed between electrically connected pairs (21) of contact rollers which are conveyed by a top and bottom conveyor (20a, b) and which themselves rotate in order to convey the printed-circuit boards at a higher speed. <IMAGE>

Title: Method for monitoring the emissions which occur when liquids are decanted with gas recirculation
Inventor: CURTIUS FRITZ
IPC: B67D7/04
Filed: 1992-06-02
Abstract: The invention relates to a method for monitoring and avoiding levels of gas which threaten the environment when liquids are decanted in conjunction with an at least partial recirculation of the gases into the supply tank. In order to provide appropriate monitoring of such gas levels, the effect of the physically different conditions above the liquid (2) in the supply tank (2) on the original gas volume above the liquid (1) are recorded and the decanting process is carried out in two operating processes,   - the actual decanting process with simultaneous gas recirculation and - equalisation of the atmosphere changing in tanks (1) and (2) and the ambient atmosphere.   Furthermore a model calculation is presented in order to simulate the decanting processes when the plants are planned. <IMAGE>

Title: Domestic refuse container system
Inventor: BOROWY PETER
IPC: B65F1/00
Filed: 1993-05-19
Abstract: The domestic refuse container system is used for the space-saving collection in kitchens, oriented towards needs and sizes, of domestic wastes which are to be disposed of separately. The preferably rectangular containers are accommodated side by side in at least one housing and can hence be operated individually. The housings can be retrofitted into kitchen units by being pushed in. The containers can be removed by the use of projecting handles or grips. The size of the containers is such as to fill the housing, providing a substantial seal against odour. The container size is adapted to the type of domestic refuse in a size-oriented manner. The refuse bags are secured by means of a push-on frame or an external handle.
Patent DE-4321671-A1 (DE)
Title: Displaceable toilet bowl
Inventor: GAAL VIKI
IPC: E03D11/14
Filed: 1993-06-30
Abstract: The displaceable toilet bowl belongs to disposal-system apparatuses and is fastened on a carriage, for example a wheelbarrow; its outlet is provided with a sleeve which, after being filled, blocks the outlet and opens it again when it is being emptied. The sleeve is connected to a mechanism by means of which it can be easily filled and emptied, for example by means of an air pump and discharge valve. After the outlet has been blocked, the toilet bowl can be pushed, instead of a pail, beneath the opening in the bed of a seriously ill individual. After defecation, the toilet bowl is coupled to the disposal system in the toilet by means of a guide device, and automatically emptied, cleaned and decoupled. The invention achieves the situation where the pail is no longer cleaned by hand and is no longer carried, which reduces the psychological discomfort of the invalid and of the carer and makes the task of the carer an easier one.
Patent DE-4324111-A1 (DE)
Title: Process and apparatus for burning mineralogical and petrographic compounds and mixtures
Inventor: MALLON JOACHIM DIPL PHYS
IPC: F27B1/28
Filed: 1993-07-20
Abstract: The invention relates to a process and an apparatus for burning mineralogical and petrographic compounds and mixtures with feed of an extracted furnace gas to the combustion zone of a shaft furnace heated with gas or oil burners. According to the process, the furnace gas is extracted from the preheating zone of the charge in a temperature-dependent manner and is then added to the combustion chambers of the burners directly or to the burners in the area of the burner mouth as a combustion medium at a temperature of 150 DEG  to 300 DEG  Celsius in a lambda-controlled circuit. This advantageously achieves higher depths of penetration of the burner gases over the charge cross-section and the burner gases cool, which prevents overburning in the burning level of the material to be burnt. The material to be burnt has a uniformly high quality and the absolute dust discharge and the pollutant emissions of the shaft furnace are decreased by up to 80%.
Patent DE-4324964-A1 (DE)
Inventor: TRAPP ULRICH DIPL ING
IPC: E05C3/04
Filed: 1993-07-24
Abstract: Door-locking device for electrical switchgear or other dangerous apparatus located behind the door. The inaccurate insertion of a key element (40) into the insertion channel (61) of a safety switch (60) is avoided by placing the locking bolt (1) in the immediate vicinity of the centre of rotation (X) of the door lock. The advantage of this position, that the warping effects of the switch-cabinet door are at their lowest here, is utilised. With the interlocking of the key element (40), its locking element (11) is interlocked at the same time. It is consequently impossible, despite an activated locking mechanism, to actuate the rotary-fastening device (53) of the cabinet door. <IMAGE>

Pref. the microprocessor controls the heat storage cycle via a relay or semiconductor switch inserted in the mains voltage supply line, the heat dissipation cycle regulated by controlling the rotation rate of the fan. ADVANTAGE - Simple, accurate heating regulation.
