Title: Torque-limiting coupling between concentric shafts - has resilient roller between cylindrical and polygonal surfaces of shafts
Inventor: STADLER DONALD A
IPC: B65G23/04
Filed: 1975-07-04
Abstract: In a torque-limiting coupling between an inner and an outer shaft, the inner shaft (16) is of polygonal cross-section while the inner periphery (24) of the outer shaft (10) is cylindrical.

Title: Thermoplastic foam injection moulding ejected rapidly - after local cooling to harden ejector thrust region of moulding
Inventor: HANNING ROBERT
IPC: B29C45/40
Filed: 1975-09-11
Abstract: The mould (after completion of injection) is initially opened a distance of a few millimetres and the moulding is subjected to local blasts of coolant in the region of the ejectors only. This causes local hardening; the mould is then immediately opened to its full extent and the ejectors expel the moulding. Several coolant blasts may be applied in succession, causing the coolant to spread between the surface of the moulding and the mould. Pref. coolants are liquefied gas, water or steam. Water may be introduced after the first coolant, to glaze the surface of the moulding. Coolant, or an additional fluid may be used to eject the moulding. Used for foam mouldings which are porous throughout, with reduced porosity near the surface, or for those with a porous core and a closed surface. Local cooling provides quickly attained local strength, permitting ejection without waiting for more extensive cooling of the moulding or mould.

Abstract: A set of push buttons for radio or audio equipment where one or more buttons may be required to remain connected while others are operated, e.g. for muting, has a pressure operated switch (13) at the end of the actuator rod (12) remote from the operating button. The contacts of ths switch are formed by the conductor wires (15, 16) which interconnect the switches. These wires are mounted behind each other so that they are directly or indirectly brought into contact. In one design, the two conductors are flat strips with an insulating strip between them, the latter having holes through it at each switch point. A protruding portion of the front strip can then be pushed through a hole to contact the strip behind.

Title: Protection circuit for voltage swing in calculator circuits - uses three transistors as detectors to generate control signal
Inventor: MIKADA HIROYUKI
IPC: H02M3/07
Filed: 1975-12-10
Abstract: A stabilised supply for electronic calculators etc. operating off a battery is provided with a circuit to provide protection against the voltage exceeding a predetermined value that can result in damage to circuit components and particularly liquid crystal display units. The main d.c. voltage converter (18) has three inputs (T1, T3, T2) that are coupled to the outputs of the protecting control circuit (S). The main terminals (T1, T2) supply power over a two position switch (SW) coupled to the battery (E).

The three control transistors (Tr31, Tr32, Tr33) are conditioned by resistors and capacitors to operate as detectors of voltage level. The generated output (T3) is used to control the stabilised voltage circuit to maintain the required range of operation.

Title: High speed sewing machine needle - with a hollow shaft to allow compressed coolant to cool needle and thread
Inventor: KLOCKE HARALD
IPC: D05B71/04
Filed: 1976-04-23
Abstract: A needle for use in high speed industrial sewing machines is axially hollow.

Title: NOR=gate with conventional two parallel transistor input - has series diode and resistor preventing input transistors saturating, to reduce switching time
Inventor: BRUECHMANN HANSJOERN DIPL PHYS
IPC: H03K19/013
Filed: 1976-07-29
Abstract: The NOR-gate consists of a conventional arrangement of two parallel input transistors (T1, T2) with shared emitter and collector resistors, and an output transistor (T3) coupled by its base to the collectors of the input transistors and with its emitter forming the output (A). A diode (D) is connected in series with a resistor (R4) across the shared collector resistor (Rc) and ensures that the input transistors do not saturate. The series resistor (R4) is one tenth of the collector resistor. This diode and resistor increase the steepness of the signal's edges and reduce switching times correspondingly.

Title: Removing impurities from solid metals - by heating and ion bombardment in very hard vacuum
Inventor: HOFMANN SIEGFRIED DIPL PHYS DR
IPC: C22B9/22
Filed: 1976-08-02
Abstract: Impurities are removed from the interior of a metal which has a temp. region with negative segregation enthalpy below its m.pt. The metal is heated to below its m.pt. so the impurities diffuse to the surface, from where they are removed by sputtering a thin surface layer via ion bombardment. Only a part of the surface is pref. subjected to ion bombardment; and the pref. solid is (a) Nb, heated to 745-895 degrees K. to remove oxygen; or (b) iron or its alloys, heated to 535 degrees - 925 degrees K to remove carbon. Used also for the removal of H2, N2, O2, H2O, CO, CyHx, from e.g. Nb, Ta, Fe or Cu alloys. The temp. required is low when compared with conventional methods for removing impurities, so that e.g. properties obtd. by cold work are not impaired as the temp. is below the recrystallisation tmep.; and interstitial impurities are easily removed.
