Title: Face sliding sealing ring - prevents penetration of harmful substances into lubricating bush and includes fitting of O=ring into bearing shield
Inventor: BENKERT STEPHAN ING GRAD
IPC: B65G53/46
Filed: 1980-12-16
Abstract: The face sliding sealing ring is used e.g in cellular wheel locks. It prevents penetration of powdery or pasty materials into the area of the lubricating bush. For this purpose the face sliding sealing ring has an adequately sized sealing wear surface so that a sufficient sealing effect can be attained without a specifically high surface pressure. The face sliding sealing ring is secured against turning by a holding pin and any penetration of media on the circumference of the sealing ring into the area to be protected is prevented by the fitting of an '0' ring into the bearing shield. Any blocking of the cellular wheel rotor as a result of compression or glueing within the rotor shaft area is therefore not possible.

Patent DE-3123649-A1 (DE)
Title: Method and device for controlling the forward-run temperatures of central heating installations
IPC: F24D19/10
Filed: 1981-06-15
Abstract: The forward-run temperatures of central heating installations are according to the invention raised or lowered via feedback of the positions of the flowthrough valves from thermostat valves in the individual rooms to a central control unit. The central control unit attempts in this case to keep all thermostat valves constantly in a state of play; it raises the forward-run temperature if one or more valves indicate "OPEN" and lowers the forward-run temperature if one or more valves indicate "SHUT". This control detects transmission and ventilation heat requirement, indirectly and depending upon the outside temperature, in the individual rooms corresponding to the actual values. According to further features of the invention, the thermostat valves can, to lower the room temperatures, additionally be acted upon in terms of temperature via electric resistances or the "OPEN" position of the valves can also be indicated by a visual check. The users can thus decide whether they accept the increase triggered by the "OPEN" position or turn back the thermostat valve and thus cancel the "OPEN" contacting.

Patent DE-3126045-A1 (DE)
Title: Short-circuit direction indicators
Inventor: HORSTMANN HENDRIK DIPL ING
IPC: H04N9/85
Filed: 1981-07-02
Abstract: The invention relates to short-circuit direction indicators for high-voltage lines fed from two ends in three-phase systems. In such devices, it is usual to use a capacitive sensor for the voltage and an inductive sensor for the current and to transfer the sinusoidal quantities via Zener diodes in trapezoidal form. It is the object of the invention to improve known devices by simple means in such a manner that they still reliably indicate even with a collapse of the voltage in the short-circuit case. This is achieved by the fact that the star or delta voltage triggers a synchronous oscillator (2) which continues to run with the correct phase in the short-circuit case and is used as phase frequency, that the signals (U20, U21) of the sensors (1, 3) are supplied to a drive logic (4) and that the drive logic (4) output is connected to a phase measuring unit (6) consisting of logic gates, the output of which feeds direction indicating elements (LED1, LED2). <IMAGE>

Title: Centreboard for surfboard
Inventor: RATHERT HORST DIPL ING
IPC: B63B35/79
Filed: 1981-12-10
Abstract: The lateral forces acting on the centreboard can be reduced by changing the centreboard setting angle relative to the flow, with the result that capsizing is prevented and higher speeds in planing operation are possible. To this end, a centreboard is proposed which adjusts itself automatically in the flow direction with most of its effective centreboard area against the action of a defined spring force. In a preferred design, the effective centreboard area can be swung out about an axis rising to the rear from the front edge of the centreboard and running at an angle of about 45 DEG . With regard to a higher speed in displacement operation, the effective centreboard area can be swung to the lee side via an adjusting device preferably to be actuated by the foot.

Title: Unassisted full-lining disc brake, in particular for motor vehicles
Inventor: KLAUE HERMANN DR ING
IPC: F16D55/06
Filed: 1982-04-16
Abstract: The brake of the invention represents an unassisted full-lining disc brake in which actuation is effected via a ring which can be swivelled in the circumferential direction, is connected by rolling actuating elements situated in oblique tracks to a ring arranged in a manner fixed in the circumferential direction and transmits the actuating force to the brake disc on one side. The reaction force of the actuating ring to the application of the second brake disc is transmitted via supporting rolling elements to a third ring. According to the invention, the supporting rolling elements are designed as cylindrical rollers which lie on two concentric circles, are guided by a cage having radial extensions and are sealed off to the inside and to the outside by axially acting sealing rings. By virtue of this measure, the brake is simpler to produce and its efficiency and operational reliability are improved. <IMAGE>

Title: Plastics ice skewer
Inventor: FLORJANCIC PETER
IPC: A47G21/00
Filed: 1982-08-04
Abstract: The invention relates to an implement, called an "ice skewer", for pure ice cubes. Because it is difficult to keep the freezing part of such ice skewers in the water until the water is transformed into the solid state of aggregation, and because many freezing compartments in refrigerators are so shallow that the length of the skewers is greatly restricted for freezing according to conventional methods, the invention proposes with a plastics ice skewer, consisting of a shaft and a solidification part, which is to be immersed into the water forming, after freezing, the ice body in the compartment of a tray of the freezing compartment of a refrigerator, that said ice skewer can be easily bent and straightened again and to this end consists of an inherently firm but still flexible plastic, e.g. a polymer of styrene. <IMAGE>
