Title: LED to indicate when telephone is engaged - has LED and transistor circuit in series with line to indicate telephone or extension usage on small plans
Inventor: STICH WOLFGANG DIPL ING
IPC: H04M1/715
Filed: 1979-11-21
Abstract: The LED indicator is for use in telephone instruments. It is particularly for parallel connected instruments, to indicate which is in use of which exchange line is in use, or for boss/secretary units, Plan 7, to indicate who is usin the exchange line. The LED is lit by the line current which is in excess of 10 mA and less than 100 mA. The circuit comprises an LED (L) connected in correct polarity to be lit by any line current flowing when the telephone is in use. A zener diode (D) is connected across in opposite polarity to prevent back biassing the LED, as overvoltage protection in conjunction with series resistors (R1, R2) in series with the LED (L), and to provide continuity in the event of LED failure. A transistor (T) is connected between the series resistors (R1, R2) the LED and the line continuation to limit the current through the LED to the required 20 mA. The circuit causes little voltage drop in the telephone loop circuit and little speech impairment.
Patent DE-2947486-A1 (DE)
Title: Continuously crosslinking of extruded e.g. polyolefin tubing - by subjecting areas to UHF field in presence of polar agent
Inventor: BEISS KARL
IPC: B29C48/90
Filed: 1979-11-24
Abstract: Plastics fabrications are produced by crosslinking in a uhf field with/without the presence of a polar agent; the process is continuous, it produces the required dimensions inside the uhf field, and the polar agent can be applied to local areas only if desired. The crosslinking reaction is exothermic so the tubing is pref. cooled after treatment also. When the tubing is to be crosslinked locally, the field can be reflected away from other areas by inserting a metal shield in the treating chamber; alternatively a polar liquid is passed through a holder at the appropriate part of the chamber. Used e.g. for extruded polyolefin tubing which can be e.g. welded at its non-crosslinked areas.

Title: Vehicle door locking system operated from one point - has actuator for moving door bolts in response to position of operating key position
Inventor: SCHWAB DITTMAR
IPC: E05B77/48
Filed: 1980-06-02
Abstract: The proposed locking arrangement is intended to simplify the mechanism for vehicle door locks incorporating an anti-theft lock. All the locks are controlled from a single key position comprising cylinder lock taking two keys and making two revolutions. One key operates the normal locks, the second key, which makes the second turn, acts on the anti-theft bolts. Mechanical linkages associated with the lock positions act by rods (21,11) on a lock control unit (6). Operating the main lock moves the relevant rod (21) which acts on a switch (35,36) to start a motor (25). Through a worm gear the motor drives a pin (30) which moves a block (24) at the end of the rod (21) into the locked position. At the same time other switches acted on by the gear wheel (29) control the motors on all the other doors and give the locked condition. Operating the lock with the second key moves a bolt (25) on the end of the rod (11) connected to the cylinder lock. The bolt prevents any further movement of the operating block (24). At the same time a switch (38) actuates the motors on the other doors causing them to turn the gear (29) to a position in which these doors are also bolted.

Patent DE-3105803-A1 (DE)
Title: Metering apparatus
Inventor: VORBACH MANFRED
IPC: A47G19/34
Filed: 1981-02-17
Abstract: Aromatic foodstuffs in powder form, such as, for example, coffee, must be stored in a sealed container in order to retain the aroma. On the other hand, this powder must be dispensed in certain, metered amounts. In this case too, contact with the environment should be avoided, if at all possible. This also applies to the possibly already premetered amount. The object of the invention is therefore to provide a metering apparatus in which the aromatic powder is accommodated in a sealed space until it is dispensed. This object is achieved by a closure on the metering device, which only opens the emptying opening to empty the metering device. The powder remaining in the container is thus always sealed. This also applies to the possibly already premetered amount. The metering apparatus according to the invention is therefore suitable for storing and dispensing metered portions of aromatic foodstuffs in powder form, which can thus be stored over a relatively long period of time without loss of quality by being sealed with respect to the environment. <IMAGE>
