Title: Crinkly glass fibres - made from 2 streams of different viscosity glass
Inventor: SCHULLER WERNER HUGO WILHELM
IPC: C03B37/081
Filed: 1971-08-20
Abstract: The crinkly glass fibres are produced by uniting streams of molten glass of differing viscosity forcing them to form a composite thread. This is pref. done employing a partioned glass melting furnace with closely spaced fibre producing nozzles in the bottom one from each bath being paired to form a composite thread. The method permits the production of controlled-crinkle glass fibres.

Patent DE-2338603-A1 (DE)
Title: Drive mechanism control - esp. of automatically operated radio aerial in direction dependent on position of switch
Inventor: LETTAU DIETER
IPC: H02P7/03
Filed: 1973-07-30
Abstract: Two monostable circuits are connected to a flip-flop via logic operation modules. The logic operation modules are connected to the switch S, so that in one position of the switch, one monostable circuit is changed-over during a limited period, whilst in the other position of the switch, the other monostable circuit is changed-over. The voltage pulses across the output of the monostable circuits start the mechanism M for a limited period. The flip-flop occupies a privileged position, when the voltage source is connected. This allows the first monostable circuit to be changed-over, when the switch S is closed.

Title: Aluminium-castings with wall-thickness increased - beyond requirements of casting-technique and above aluminium melting-point
Inventor: HELLING WERNER DR ING
IPC: B22D21/00
Filed: 1973-08-20
Abstract: In order to enhance skin-formation on the castings, which is desirable for resistance to weathering, the wall-thickness of the castings is increased during casting beyond the requirements of casting-technique and of strength of material and then reduced mechanically by >=50% of the rear thickness. The casting operation is carried out at a higher temp. than usual, viz. 690-730 degrees C after preheating the alloy to 760-840 degrees C before casting. The part forming the inside of the casting contains substances which are substantially non-oxidising.

Title: Reading circuit for phase encoded data - gives precise synchronization of reading operation and recording medium speed
Inventor: MUELLER OTTO
IPC: G06K7/016
Filed: 1973-09-15
Abstract: The clock signals at the reading head are automatically synchronized with the data carrier drive motor. The motor is operated at a fixed voltage, whilst the reading head clock signals are controlled by a clock generator whose frequency depends on motor speed and is regulated in proportion to variations in motor speed. A disc may be coupled to the motor to produce speed pulses and the time difference between the clock generator pulses and the speed pulses is used to derive signals which are integrated to obtain a control voltage for the clock generator oscillator.

Title: Drying container interiors - hot combustion products are fed in through probe inserted into container
Inventor: WITHEY DONALD SIDNEY
IPC: F26B21/00
Filed: 1973-11-08
Abstract: Containers are dried after washing or testing, by insertion of a probe through which gas is fed in and can flow out of the container opening. The gas partially consists of hot combustion products from a fuel and an O2-contng. gas. Pref. the probe is inserted into the container to a depth of at least half the max. length of the container interior. The container is rotated while the gas is led in, and the probe is horizontal. Before the hot combustion products are fed in, a gas is introduced to drive out moisture in the container. After the combustion products, a gas may also be fed in, to drive out residual traces of moisture or fuel residues from the combustion. The fuel may be a gaseous hydrocarbon. Large numbers of containers can be quickly dried.

Title: Potentiometer plate base material - consists of inorganic fibre-filled polyamide
Inventor: SCHILL OTTO
IPC: H01C10/00
Filed: 1973-11-21
Abstract: A base matl. for potentiometer plates which are provided with insulating strips consists of a polyamide filled with a fibrous reinforcing agent. This matl. overcomes previous problems with such plates made of hard paper (burning of the paper when applying the resistive strip, peeling off of the latter, breakage when affixing contacts etc.). It is also cheaper (by about 50%), lighter and more economical than hard paper (plastics-impregnated paper).
Patent DE-2402698-A1 (DE)
Title: Forming rollers for cylindrical component - progressive undercut on inclined sides of forming wedge
Inventor: KOIZUMI MOKUJI
IPC: B21H1/18
Filed: 1974-01-21
Abstract: When a cylindrical component with reduced diameter over its central section is produced by forming rollers, a considerable tensile force is set up by the tapered sides of the forming wedges. Since this tensile force is a function of the taper angle and the diameter reduction ratio, it is a limiting factor on roller forming. By progressively undercutting the tapered sides, starting with no undercut at the thin end of the forming wedge, the tensile force set up decreases from a maximum at the beginning of the forming process to zero at the end of it. This leads to an improved diameter reduction ratio and thus a higher rolling efficiency.
Patent DE-2405003-A1 (DE)
Title: Pulsating nuclear reaction rocket motor - uses recoil of neutrons from pulsating fission-fusion lithium deuteride-tritide reaction
Inventor: FISCHER ALBERT GEORGE PROF DR
IPC: F03H99/00
Filed: 1974-02-02
Abstract: Pulsating nuclear reaction rocket motor has hot, magnetically self-compressing max.-press. plasma channels produced by rapid periodic capacitor discharges through a mass of molted 6Li-deuterotritide. In the channels, primary neutrons initiate fission-fusion avalances which run toward the hollow cathode, through which the neutrons can then escape as a beam into space, producing a reaction force. Preferably the directed neutron flux is used, which meets a discharge plasma focussed by its azimuthal magnetic field, so that the neutrons resulting from fusion are scattered forward by the releasing impacts and can then escape through the cathode, which is constructed as a neutron window. The reaction force is 109 kp per pulse, and can be used to drive vehicles, ships, aircraft and space vehicles.

Title: Multiple switching and alarm device - is for carrier supply equipment in carrier frequency systems
Inventor: HORNUNG FRANZ DIPL ING
IPC: H04B1/74
Filed: 1974-04-09
Abstract: The device switches in a stand-by unit in phase controlled oscillators, and at the same time monitors output levels and synchronism of operating and stand-by oscillators. Similar switching means are provided on the operating and replacement side for each side control. Criteria for level and synchronisation are on both sides applied to a monitoring circuit. Synchronisation criteria are generated in synchronisation detectors before the switching over contacts, while the level criteria are generated by rectifiers following the contacts. A monitoring circuit is connected to first inputs of two first NAND gates, and these inputs are interconnected by diodes of opposite polarities; their second inputs are disconnected for operation and replacement, and their outputs are connected to a first pair of terminals and also to first inputs of two second NAND gates.

Abstract: The gauge employs a float which drives an indicator. The float contains a ring of ferromagnetic material which cooperates with a follower of similar material. The follower is coupled directly to the indicator and rises and falls with the float as a result of magnetic attraction. The float is preferably ball-shaped with a central bore to enable it to be mounted on a tube. Pref. the follower is inside the tube and is attached to one end of a measuring tape coiled on a spool in a transparent casing sealed onto the top of the tube.
