Title: Cathode ray tubes - with arc limiting coating in the envelope comprising an insulating oxide, graphite and a silicate binder
Inventor: GALLARO ANTHONY V
IPC: H01J29/88
Filed: 1979-05-25
Abstract: CRT comprises an envelope with a conical section and a neck, with an anode button sealed into the cone. A mounting assembly carrying damper elements is sealed into the neck. The interior of the envelope is coated with an adherent layer of a compsn. to limit the formation of arcs, comprising particles of an insulating oxide (I), particles of graphite (II) and a silicate binder (III), with a wt. ratio of (I):(II) of 5:1 to 16:1, the resistance of the coating being 5 kg-ohms to 1000 kg-ohms, measured between the anode button and the damper elements. The coating replaces prior art conductive coatings used as a discharge path for secondary electrons emitted from the perforated screen as a result of impact of the prim. electrons on the screen. The new coatings limit arcing over the conductive coating, which can have the effect of damaging transistor circuits by surge currents resulting from the arcing.

Title: Alarm system with loop resistance monitor - has voltage discriminators and time delay to detect manipulation
Inventor: BEIGEL HELMUT
IPC: G08B29/06
Filed: 1979-06-09
Abstract: An alarm system is switched from OFF to ACTIVE by switching more resistance into the activation loop. The loop resistance is continuously monitored by pairs of threshold voltage discriminators connected as 'window circuits'. The whole range from zero to infinity is covered by 5 windows, corresponding to SHORT-CIRCUIT, OFF, TRANSITION, ACTIVE, OPEN-CIRCUIT, and their outputs are processed by logic gates to operate indicators and an alarm. The TRANSITION window has a delay and only gives an output if the loop resistance is within its limits for longer than 5mS, which is taken to indicate 'manipulation'. The logic gates are arranged so that the system remains in the same state, i.e. OFF or ACTIVE, despite outputs from other windows.

Patent DE-3005445-A1 (DE)
Title: Receiver device for telegraphic data - has microprocessor and ring counter for automatic timing of bit sampling pulses
Inventor: AUTENRIETH GERHARD ING GRAD
IPC: H04L25/06
Filed: 1980-02-14
Abstract: The circuit is capable of converting a data stream of unknown bit rate and unknown number of synchronising bits over and above one and consists of a pulse edge sensor circuit (4) which is connected to the data line (1), a ring counter (3), a programmable microprocessor (M), a comparator (V) and a logic level sampler and digital output circuit (A). The clockrate applied to the ring counter is several times larger than that of the expected telegraphic bit rate and counts continuously providing the microprocessor with a time reference for measuring the bit width of the synchronising bits. From this and the microprocessor program, the time interval in terms of counter clock pulses is calculated at which the first data bit level is to be read out. The clock counter is signal inputted to the comparator (V) and when the counter (3) produces this count output the comparator generates an enable pulse spike for the readout of the logic level in the data stream. This yields the level of the first bit and subsequent bits are read out along the same principles.

Title: Heating-cooling roller - uses fluid eddy developed by internal chambers for heat exchange
Inventor: CHRIST ALFRED DIPL ING
IPC: F16C13/00
Filed: 1980-02-12
Abstract: The chambers lying at right angles to the roller axis, to develop an eddy effect in the temperature control fluid, have roughly a quadrilateral internal cross section. The openings of the fluid channels, to support the eddy development, lie in front of the fluid outlets, in the direction of roller surface rotation. The pressure in the chamber is less than 5 bar, and the total pressure waste in the fluid feed is less than 5 bar. The design gives a roller where the surface can be heated or cooled, in a cheap construction, using a heat exchanger that is not sensitive to pressure changes, and requires little pump capacity.

Title: Metal pins inserted into plastics baseplate esp. for dental patterns - by hot plate pressing pins into holes in plate
Inventor: ZEISER MANFRED P DR
IPC: B29C65/44
Filed: 1980-03-05
Abstract: An apparatus for pushing metal pins into receiving bores in a plastics base plate is intended esp. for producing dental patterns. The base plate is placed on a seating beneath a heated plate; the seating is then raised by a lifting mechanism towards the heated plate, so that the latter pushes the pins into the base plate, at the same time heating them by contact at their upper ends. The seating plate, pref. has a heat-reflecting surface on the upper face. The metal pin used has an arrow head shaped portion of slightly greater length than the depth of the hole in the base plate. Preferably, this portion is 0.5-2 mm (1 mm) longer than the thickness of the base plate. More specifically, the arrow head portion is 11 mm in length. The process is based upon the concept of not heating the metal pins until they are already seated in the plastics base plate. The pin then penetrates into the baseplate as soon as the heat reaches its tip.
