Title: Integrated switch using single conduction type transistors - carries out making or breaking connections through source and drain paths
Inventor: DANGEL JUERGEN DIPL PHYS
IPC: H03K17/16
Filed: 1975-10-18
Abstract: An integrated circuit with MOSFET's of only one conduction type is used for switching, where making and breaking takes place in the source-drain paths.

Each switch (T1) gate is connected to the output of an inverter (I) consisting of transistors (T2, T3). The inverter (I) input is controlled by a logic circuit (L), and both inverter and logic circuit are connected to a first, higher supply voltage, and to a second, lower supply voltage of opposite polarity. Conducting paths are approx. at zero potential. The load transistor (T2) of the inverter is a depletion type transistor.

Title: Valve for hydraulic mine prop with resilient seal - using gas pressure to apply seal to valve housing walls
Inventor: WIDMAIER DIETER ING GRAD
IPC: E21D23/16
Filed: 1975-10-31
Abstract: The vale comprises a resilient sealing member which is applied by gas pressure to an inner wall of the valve housing in which are located spaced-apart fluid inlet and outlet. On the gas side of the resilient sealing member is a partition of gas-impermeable material. Pref. the partition consists of a polyvinylidene chloride film which is thinner than the sealing member, and which is adhered to the sealing member and turned back over its edges. The material of the partition is far less gas-impermeable than that of the sealing member, and less elastic, which however is unimportant, as the partition is located on the gas side and not on the liq. side, where overflow occurs. As a result, gas pressure remains constant, and so also does the switch-off characteristic of the valve.

Patent DE-2558375-A1 (DE)
Title: Control circuit for DC convertors - has pulse generator for transistor control and pulse transformer
Inventor: NICOLAUS ROBERT
IPC: H02M3/335
Filed: 1975-12-23
Abstract: The pulse transformer is provided between the pulse generator and control path of the control transistor. It has one or two different control windings for generation of switching on or blocking pulses. They are periodically connected to a capacitor in turns. Charge and discharge process of the capacitor is controlled by an auxiliary circuit, so that when the dc convertor is switched on or off, generation of pulses able to trigger the control transistor is suppressed when the capacitor voltage for blocking pulse generation is below the nominal value.

Title: Timer for West German telephones - tells caller of imminent expiry of four minute tariff unit
Inventor: DRIGNATH ROLAND
IPC: H04M15/30
Filed: 1975-12-02
Abstract: The four-minute timer, for West German telephones, informs the user, typically 15 seconds before the end of the new 4 minute tariff unit, (in West Germany) that this time period is coming to an end. This is achieved with a timing device actuating a bell, buzzer or visual display. The size of the timer is roughly that of a cigarette packet. Telephone conversation continues only at a higher charge rate than that for a minute call (23 Pfg. at date of specification).

Title: Copier using magnetic brush and semiconducting toner - induces charge in drum for image development but kept from toner particles by insulation on brush
Inventor: NISHIHAMA HITOSHI
IPC: G03G15/09
Filed: 1976-02-10
Abstract: The copier uses a magnetic brush and semiconducting toner. The brush is covered with an insulating coating (7) with a resistance of at least 103 (pref. 105) ohm/cm2. When the electrostatic image is developed, a charge is induced in the drum (8) by the magnetic brush, but due to the insulation (7) not in the conducting or semi-conducting toner particles, which are thus less liable to adhere to the uncharged image areas. The corona discharge transferring the toner to paper has its lines of force more upright; its voltage does not vary by more than 3000 (pref. 2000) V nor oscillate more than 50 times while a point of the paper passes. The toner particles are ellipsoidal with dia. 3-20 (pref. 7-15)u.

Title: Self-tuning bandstop filter - has compensating voltage controlled by phase comparator to bring output voltage to zero irrespective of frequency setting
Inventor: FLIEGE NORBERT DR ING
IPC: H03H21/00

The filter is tuned without range switching and without intervention by hand. The second-order active filter network (1) has both a bandstop output (3) and a bandpass output (4). A bipolar gain-controlled amplifier (8) is connected to the bandpass output and passes a compensating voltage to an adder (9) coupled to the bandstop output. The amplitude and polarity of this compensating voltage are controlled by a phase comparator (7) that receives equal phased inputs when the filter is tuned.

Title: Synchronising system for data transmission stations - combines sync. character with blank character, to prevent incorrect synchronisation
Inventor: PREY GERHARD
IPC: H04L7/04
Filed: 1976-09-24
Abstract: The synchronising system, for data transmission systems, synchronises data blocks of equal length. These data blocks contain both the wanted data and internal control/instructions. Each synchronisation character has added to it a second character (blank character) to give a single bit configuration. This bit configuration ensures that incorrect synchronisation cannot occur because wanted characters can never combine to give a configuration that is identical with the sync. configuration.

Abstract: Hard, austenitic manganese steel, esp. Hadfield's steel, is made by melting in a furnace provided with a basic refractory lining, at 1400-1600 degrees C., followed by casting at 1375-1525 degrees C in a mould. After casting, the cast prod. is cooled in its mould to 960-1150 degrees C., then removed from the mould and immediately quenched. After removing the casting from the mould it may be subjected to a brief period of intermediate heating at 1000-1100 degrees C before quenching. The invention is designed to reduce the process time; save energy costs; minimise the risk of cracking and also the loss of carbon; and to retain a small grain size).
