Title: Inductor and transformer with low magnetic resistance from DC to HF - uses two ferrite half-cores with parallel magnetic fluxes
Inventor: YAMASHITA HIROSHI
IPC: H01F3/10
Filed: 1974-02-06
Abstract: The inductor transformer is fitted with a ferrite core with a narrow airgap, having a low magnetic resistance for an HF magnetic field and a winding on the core. It has a further magnetic core with low magnetic resistance for dc and LF magnetic fields. The dc/LF magnetic ore is built up from a series of laminae arranged together with the HF magnetic core resulting in a parallel magnetic flux path with regard to the applied magnetic field. The width of the airgap has to fulfil a given set of mathematical conditions involving the airgap width; the magnetic flux path length of both cores, and the magnetic permeabilities of the cores. The arrangement results in an inductor/transformer which has excellent magnetic properties for composite dc, ac currents such as a low magnetic resistance from dc up to HF frequencies.

Title: Loom has shuttles moving in closed path - including shed and yarn feeders having clamp to release yarn at start of picking
Inventor: HOLUB JOSEF
IPC: D03D47/26
Filed: 1974-10-22
Abstract: A loom has a number of yarn feed evices 8 including a housing for receiving a shuttle and contg. a weft yarn supply package from which yarn is wound onto a spool on the shuttle a yarn damp comprising a pair of jaws being provided on the housing to clamp the yarn between the shuttle and the yarn supply package.

Title: Device to prevent skis crossing - has torsion spring loaded lever which deflects under excessive load
Inventor: SCHWEITZER HORST ING GRAD
IPC: A63C5/065
Filed: 1975-04-15
Abstract: A bracket (1) which is fixed to the ski (13) has two bearing blocks (2) at one end. The bearing blocks support a pin (4) which passes through an elongated hole (6) in the lever (5). The lever (5) is maintained in the vertical position by a torsion spring (9) which keeps the rounded end of the lever in the hole (10) of the bracket (1). If one ski tends to cross over the other, the lever (5) resists this tendency until the spring force is overcome when the lever rotates through 90 deg. in a counter-clockwise direction. This prevents the skis from becoming jammed in the crossed-over position as is the case with existing devices of this sort.

IPC: H02P1/42
Filed: 1975-04-26
Abstract: The apparatus has a base plate (11) with a swing arm (14) on whose free end there is a magnetic element (27) with a moving contact (19) and a fixed contact (20) the latter being mounted on the base plate opposite to the moving contact. The moving contact arm is spring loaded and is held at a predetermined distance from the fixed contact. The base plate (11) is made from insulating material and swing arm (14) from conducting material. The switching arrangement can be mounted on the enclosure of an induction motor (13); its free end protrudes into the motor such that the magnetic element (27) is in the viscosity of the main winding yoke (25). The element is attracted by the yoke during starting of the motor.

Title: Detachable mounting for shock absorber - uses second central plate in upper mounting to allow easy release of damper
Inventor: MUELLER ERNST ING GRAD
IPC: B60G15/06
Filed: 1975-05-09
Abstract: The independent suspension has a telescopic shock absorber mounted inside a spiral spring positioned between the upper part of the wheel mounting and the body. The upper end of the spring is braced on the body by a pressure plate, bolted to the body. The plate had a central opening over which a second, smaller plate is bolted to support the upper end of the shock absorber. The plate is removed when the shock absorber is exchanged so that the spring remains in place and no special clamps, etc., are required. The second plate is accurately located on the main plate by slots rather than bolt holes.

Title: Additional torque screw driver rotary grip - engages rotation and hold arm when intermediary components axially pressed together
Inventor: BOTOND BELA
IPC: B25G1/10
Filed: 1975-06-16
Abstract: The rotary grip for screw drivers comprises a rotary cylinder (1), and a rotation and hold arm (2). Connection between the cylinder and arm is assured by a connecting shaft (3) and a coupling part (4), together with an intermediary tensioned spiral spring (5). The rotary and hold arm, formed to transmit high torques, and connected to the rotary cylinder, only begins to grip when the coupling parts between both parts are pressed together through the exertion of an axial pressure. This must overcome the force of the spiral spring (5) holding them apart, and the rotary cylinder (1) in engagement with the tool insert is thus joined by the rotary and hold arm (2) to transmit a high torque.
Patent DE-2529723-A1 (DE)
Title: Removable lever for roof panel - with clipon slot for operating spring connected to release catch upper end
Inventor: STAIGER HELMUT
IPC: E05C5/04
Filed: 1975-07-03
Abstract: The vehicle roof panel is operated by detachable levels (3) which clip onto the operating shaft of the catches. The upper end of the catch has a spring with a profiled loop which locates in a slot in the operating level, when the latter is attached. The spring is set to align with the lever fitting direction when released. The other end of the spring is secured on a adjustable support (14) which is located on a set of ratchet teeth to alter the tension. The system is an improvement on the conventional recirculating ball lever in which the ball is easily lost, and in which the lever coupling is weaker.

Title: Filter for vacuum cleaner - includes reinforcing plate which is centered on sealling ring by prongs engaging slots in plate
Inventor: STETTNER GERHARD ING GRAD
IPC: A47L9/14
Filed: 1975-07-26
Abstract: The filter (1) forms part of the dust bag (5) of the vacuum cleaner. A rectangular reinforcing plate (2) is fitted over the mouth of the bag (5). The reinforcing plate (2) has a central hole (6) with a small slot (7) near each end. The rectangular lid (8) is provided with a sealing strip (9) to match the plate (2). The lid (8) is provided with two prongs (10) with rounded ends. When the lid (8) is fitted over the reinforcing plate it abuts against the support ring (4). At the same time the prongs (10) engage the slots (7) and centralise the plate (2) on the sealing strip (11). This ensures that a perfect seal is made so that the efficiency of vacuum cleaner is not impaired.
