Title: Aluminium alloy vacuum casting machine - has chill mould attached to tilting ladle spout and vacuum applied to airtight ladle during casting
Inventor: JUNGHANNS PAUL
IPC: B22D27/15
Filed: 1978-07-31
Abstract: Titling ladle carries the chill mould on a casting spout and in the tilted position the spout lies below the molten pool level. The space on top of the pool level is enclosed airtight by a sealed lid and charging door; during the casting operation it remains connected to a vacuum system. The tilting ladle is pivoted by trunnions to a pedestal. The metal pool is kept hot by electric heating elements in a tube. The spout carries one half of the chill and a casting nozzle. The other half is carried by a swivelling arm. This ensures a uniformly high quality even when the metal level has become lower by repeated casting cycles. The repeated vacuum application results in a degassed casting, free from oxygen or hydrogen pickup.

Title: Solidification and disposal system for dust-like radioactive waste - uses lidded storage vessel positioned in dump vessel evacuated so that solidification agent can be sucked in
Inventor: BAATZ HENNING DR
IPC: G21F9/36
Filed: 1978-08-29
Abstract: The storage vessel with its liq. in position but loosened is introduced into a dump vessel for permanent disposal of the waste. The storage is fixed in position inside the larger dump vessel, the lid of the dump vessel is fitted and vacuum is applied. The vacuum causes the lid to jump off the storage vessel and simultaneously sucks out the dusty radioactive contents from the storage vessel into the dump vessel interior. The solidifying agent is then sucked in by the vacuum inside the dump vessel, to stabilise the active dust. Finally, the vacuum connection and the solidifying agent connection are closed. Pref. the entire dump vessel with the storage vessel inside it is tilted so that its axis is inclined and the whole assembly is then rotated about a horizontal axis. No remote handling of the lid is required.

Title: Line balancing network for power supply circuit - has full-wave diode rectifier bridge to draw dc of any polarity and give improved side-tone effect on long lines
Inventor: LEISTNER RUDOLF ING GRAD
IPC: H04M19/08
Filed: 1978-09-05
Abstract: The subscriber supply circuit allows additional subscriber stations to be added without reducing the current available for the microphone circuit. The circuit includes the usual cradle switch (GU), microphone and transformer-coupled ear-piece (H1U). The line balancing network comprises a capacitor (C), full-wave rectifier bridge (G), characteristic resistance (Ri) across one diagonal of the bridge. Across the other diagonal of the bridge, i.e. the output, is connected a parallel circuit consisting of the additional load (V) and a resistor (R1). The rectifier bridge allows DC to be drawn irrespective of polarity and because of the dynamic resistance of the diodes it improves side tone effect on long lines. Alternatively, the additional load can be connected in parallel with a rechargeable battery which is connected to the bridge.

These signals are monitored by a portable receiver carried by the driver so that he can tell immediately the vehicle is driven away. The security system is undetected by the thief. The receiver has a comparator circuit and an alrm so that a change in the signal, representing the vehicle position being changed, initiates the alarm.
Patent DE-2843867-A1 (DE)
Title: Hydrostatic sediment extraction - using communicating tubes with swivelling intake and outflow sections
IPC: B01D21/24
Filed: 1978-10-07
Abstract: A pumpless system for the extn. of liq. sediments and sludge, esp. for activated sludge to be recycled or surplus sludge in a sewage treatment plant, uses the hydrostatic pressure difference instead. Vertical tubes have at the bottom a swivelling intake section and at the top a swivelling outflow section so that the specific layer to be extracted can be selected by adjusting the former, and the rate of extn. (pressure differential) by adjusting the latter. This saves much capital investment and power by replacing pumps through communicating pipes. The system can be controlled manually or automatically by turbidity meters.

Patent DE-2921721-A1 (DE)
Title: Riveting system for composite materials - uses tubular rivet with flanged end to protect soft plastic component
Inventor: GUENTHER ROLF
IPC: B23P11/00
Filed: 1979-05-29
Abstract: Conventional methods of blind riveting are unsuitable for use with composite materials as the force required to expand the head will damage the soft part. This difficulty is overcome by using a tubular rivet (10) with a countersunk head which is inserted through the metal component and projects beyond the surface of the soft material. A special tool (13) is then used to spread this projecting end outwards (10a) to grip the soft material surface. A conventional blind rivet (14) can then be used, with the head (14a) formed, by collapsing the outer sleeve, abutting against the flanged end of the tubular rivet (10).

Title: Solid electrolyte capacitor - comprising dielectric oxide layer coated with sintered valve metal anode, semiconducting oxide cathode covered with graphite and metal layer
Inventor: SCHNABEL WERNER DIPL PHYS DR
IPC: H01G9/18
Filed: 1979-06-11
Abstract: Solid electrolyte capacitor which consists of a dielectric oxide layer provided with a sintered valve metal anode and a semiconducting metal oxide as cathode, which is covered with a graphite layer and a metallic conductive layer serving as current lead, is described in which this layer is interspersed with a framework of insulating particles. The layer may also contain reactants. The capacitor is placed in a metal can and sealed in with a plastics filling, esp. epoxy resin. In the event of shorting out of the capacitor due to breakdown an insulating skin remains present on the anode preventing the breakout of fire locally, which may produce distortion in neighbouring components, which in turn may lead to further breakdown. The insulating framework has an elastic or plastic structure which protects the anode against stress during assembly and against the effects of thermal work.

Title: Ink jet printer control for precise performance - has profile giving optimum geometry of ink jet nozzle to regulate droplet delivery
Inventor: KOBAYASHI MASATSUNE
IPC: B41J2/135
Filed: 1980-02-05
Abstract: The nozzle element of an ink jet printer is designed to allow accurate control of droplet delivery without exhibiting undue sensitivity. The nozzle element is provided by a glass tube (2) with a profiled nozzle section on one end (6). The surface of the tube (10) is coated with an electrode deposition and this forms part of an electro-mechanical pulse generator together with an outer tube (11) also with an electrode coating. When the generator is activated by signals applied(12, 13) to the electrodes, a pressure pulse is produced in the fluid within the nozzle section. The consistency and sharp cut off of the droplets produced depends largely upon the nozzle geometry. The nozzle exit angle should lie between 0 and 45 degrees and the inlet angle 20 to 60 degrees for optimum performance.

Title: Ship-speed measurement system for marine log - uses static and dynamic pressure difference across piston held by strings whose resonant frequency is checked
Inventor: RUNGE RUEDIGER
IPC: B63B9/00
Filed: 1980-02-13
Abstract: Static pressure (8) is applied to one side and dynamic (7) to the other of a piston (2) held in place in a cylinder (1) by longitudinal taut strings (3,4). Each string has an electromagnet type oscillator (9,10) associated, and a transducer (11,12) for picking up its resonant frequency. A comparator (15) establishes the frequency-difference which is a measure of the speed. The piston may be sealed to the cylinder, using an elastic substance (17) such as silicone-rubber. High accuracy is achieved since the pressure difference can be directly converted to digital signals. The resonance frequency is linearly dependant on the tensioning of the strings. Interference effects such as temp. changes are equalised by the opposite sides.

Filed: 1980-06-13
Abstract: Common emitter type transistorised transmitter amplifier arrangement is designed to avoid transistor damage as a result of break-through of the collector-base barrier layer, commensurate with the lowest possible design costs. To meet the safety requirements, a control circuit is provided to adjust the driving d.c. voltage (Uo) when, as a criterion for bringing in regulation, a threshold value is reached by the base-emitter voltage, at which the latter voltage changes in the positive direction as a result of breakdown of the collector-base barrier layer.
Patent DE-3023560-A1 (DE)
Title: Control circuit for stepping motor - uses only one half cycle of AC supply and has diode between supply and winding common point
Inventor: MERKLE PAUL
IPC: H02K19/06
Filed: 1980-06-24
Abstract: The application is to a motor using current pulses to provide the moving field causing rotation. The pulses are applied at intervals as determined by a switching logic as set out in the original patent application. In order to utilise an a.c supply directly from the mains as a power source, and prevent alternate magnetisation of the machine core, a diode (13) is placed in the common connection between the supply (14) and the stator windings (1-6). The actual switching is by transistors (7,8,9) in the winding paths. If a three-phase supply is used, one diode per phase is needed. The diodes can be inserted in the connection to the transistor emitters (a,b,c).
Patent DE-3030450-A1 (DE)
Title: Wall-covering with relief pattern - produced by colour overprinting of foamable plastic motifs before foaming to preserve sharp contours
IPC: B41M3/18
Filed: 1980-08-12
Abstract: A wall covering with a relief pattern is produced by printing discrete motifs in a coloured, foamable plastic soln. on a base material of paper, plastic film, etc., and then drying to temporarily stabilise the plastic soln. The pattern is developed by the application of non-foaming pigments in one or more further printing operations, overlapping with the previously-applied foaming motifs. The foaming plastic material is subsequently allowed to foam, giving a high-relief pattern in which the contours and the register of the overlying colours are sharp and continuous. This obviates the difficulties of achieving sharp, continuous printing contours over a base of varying thickness.
