Title: Central electrode design for a spark plug
Inventor: SAKURA AKIO
IPC: H01T21/02
Filed: 1987-10-19
Abstract: In a central electrode design for a spark plug which contains a tubular insulator whose inside has a stepped set-back shoulder, in order to construct a bore of reduced diameter therein, a central electrode is provided which has a flange and is inserted concentrically into the insulator, the flange engaging with the shoulder and one end passing axially through the bore so that it is exposed towards the outside of the insulator. The central electrode has an electrically conducting core made of copper or a copper-based alloy, which is enclosed in an encapsulation made of a nickel-based alloy which is resistant to oxidation and heat. The core is provided with a number of breaks in its grain structure, so that the thermal stresses are absorbed by the differential thermal expansion between the core and the encapsulation.

Title: Pneumatic vehicle tyre with pressure-resistant bead core
Inventor: PFAFF DANIEL
IPC: B60C15/04
Filed: 1988-08-31
Abstract: The invention relates to a pneumatic vehicle tyre with a carcass which is wrapped around bead cores, of which at least one is subjected to pressure during operation. To avoid buckling of pressure-loaded bead cores of pneumatic vehicle tyres, without making it more difficult for these types to be fitted onto one-part rims, it is proposed according to the invention that the pressure-loaded bead cores consist of a shape-memory alloy which changes in its crystallisation at a temperature between 60@C and 95@C.
Patent DE-3833053-A1 (DE)
Title: Air bearing element
Inventor: KLUESENER-TRAUTMANN ROSWITHA
IPC: F16F15/027
Filed: 1988-09-29
Abstract: Serving for bearing machines and machine foundations so as to isolate vibrations is a bearing element which is formed by a closed air cushion. Said air cushion is connected to further air cushions, resulting in the overall bearing, via an annular line and is provided with an air pressure dimensioned to correspond to the respective weight. It is thus possible to disconnect the machine or the machine foundation from the understructure to the extent that transmission of vibrations is ruled out. The handling of the bearing element is very simple, both assembly and disassembly being possible by filling or emptying. Furthermore, adaptation to changing circumstances can be carried out in a simple manner by changing the compressed air in the annular line so that the desired optimum disconnection is always guaranteed. A further advantage are the small constructional dimensions so that the system of air cushions is suitable, in particular, also for such applications where there are unfavourable construction conditions. <IMAGE>

Patent DE-3904363-A1 (DE)
Title: Voltage regulator
Inventor: BERGMANN GUENTHER DR ING
IPC: G05F1/569
Filed: 1989-02-14
Abstract: A voltage regulator is described, in the form of a monolithically integratable circuit arrangement according to the principle of linear longitudinal voltage regulators with a start circuit, the equivalent power rating of which is decreased in the case of a high admissible input-voltage range by providing measures which are intended to limit the current through the start circuit and to divert an excess current in the current path to the start circuit which occurs at high input voltages to the output of the voltage regulator and thereby to provide it to the load.
Patent DE-3907022-A1 (DE)
Title: Process for producing sintered parts from fine metal or ceramic powders
Inventor: POETSCHKE JUERGEN PROF DR ING
IPC: B22F1/052
Filed: 1989-03-04
Abstract: To produce the sintered parts, powders having a particle size of up to 500  mu m and a particle size distribution close to the "Fuller distribution" are used. The multicomponent binder added contains at least one component which forms a liquid phase below the melting/softening point of the other component(s), while these solidify to form a sponge-like skeleton having pores going right through. The amount of the liquid phase is selected in such a way that, after it is removed by chemical means, there remains in the shaped part a free pore volume matching the sintering process. The remaining components are then thermally decomposed under optionally pulsating, superatmospheric pressure above their decomposition temperature and above the temperature at which the powder particles just begin to grow together, in a gas atmosphere whose carbon or oxygen activity corresponds to the respective carbon or oxygen activity of the shaped part. Decomposition gases remaining therein are removed by vacuum treatment, before the shaped part is sintered to closed porosity in vacuo at temperatures below the material flow point and is finally densified isostatically under inert gas.
Patent DE-3925373-A1 (DE)
Title: Casting metal shapes - involves metal drawn into mould by vacuum and then subjected to positive pressure
Inventor: TEGNEMO NILS LAGE INGEMAR
IPC: B22D27/13
Filed: 1989-08-01
Abstract: Molten metal is drawn upwards through one or more inlets into a mould in the process. A vacuum is applied so that the molten metal fills the mould and rises into at least one riser pipe. The metal in the inlets to the mould is caused to harden as soon as a required level in the riser has been reached, so that the molten metal is enclosed in the mould. The mould is then pressurised. The hardening of the metal in the inlet is produced by a redn. in the velocity, or a cessation, of the entry to the mould and is in the form of a slot whose width is less than that of the thinnest section of the shape being cast. The mould may be enclosed in a gas-tight cover for the application of the vacuum and pressurisation. USE/ADVANTAGE - Used in the casting of metal shapes for various uses. The molten metal is enclosed in the mould before it can harden, so that the application of an external pressure can be used to ensure that all of the mould is completely filled. No valves are used, thus making the process simple and economical, since it is difficult for valves to survive the temps. involved in the casting of molten metals.

It is guided by a slotted sleeve (25) surrounding the spindle (15), and carries a cam (33) which protrudes through the slot (35) to actuate the switch (37) by engagement with its lever. The sleeve is coupled to the spindle through a redn. gear (41, 43, 45) which extends the travel of the nut per revolution of the spindle without mechanical weakening of the thread, which may be shaped to impart reciprocating motion to the nut. ADVANTAGE - The switch is operated in a direction of axial movement of the spindle nut to increase range of monitoring.  Construction is simple and robust, giving extensive travel despite comparatively small size.

IPC: D01H1/00
Filed: 1990-01-26
Abstract: Apparatus for the production of staple fibre yarn employs spindle assembly units (1-5), a drawing frame (14) and spooling units (6-9). Two centrifugal spindles (10, 11) are mounted in some of the assembly units (2 to 4) while the end units (1 and 5) possess just one spindle (10).
