Title: Perforated vibrating container - for preloading particulate moulding materials to automate control of wall thickness and/or density
Inventor: MUNK EDMUND
IPC: B27N3/14
Filed: 1977-03-04
Abstract: A device for prefilling a compression mould cavity with a particulate material, comprises a container with a perforated base which can dump material into the cavity to a level controlled by the position of base of the device above the base of the cavity. The container is mounted on (rubber) supports which allow the container to oscillate along one or more axes and/or in a rotary motion to cause the particles to pass through the perforated base. Used for filling moulds which controlled amounts and/or distributions of e.g. resin impregnated wood particles for moulding worktops, bins etc. Can be used to mould undulating profiles of constant wall thickness and/or mouldings with controlled variations in wall thickness or density. The amount of material is limited by material ceasing to flow through the base one the cavity is filled to the base of the holder, even if oscillation continues. Excess material can be removed still in the container after stopping oscillation. Control of fill distribution allows wall thickness control on sloping parts of the moulding.
Patent DE-2710344-A1 (DE)
Inventor: BIERI HANS
IPC: H01R39/04
Filed: 1977-03-10
Abstract: In the case of a commutator for an electrical machine, the outer envelope surface of the commutator carrier (2, 3) and the side of the laminates (7) facing the commutator carrier (2, 3) each have a tooth-like surface (5, 8) in the axial direction. The laminates (7) are connected to the commutator carrier (2) by means of a solidified medium in a gap (9) between the laminates and the carrying part (3), at least the surface of the carrying part (3) of the commutator carrier (2, 3) facing the laminates (7) being provided with an insulation layer (6). The tooth-like surfaces (5, 8) of the laminates (7) and of the commutator carrier (2, 3) have means (10, 11) for anchoring the solidified connecting medium in the gap (9), which medium is cured synthetic resin. The advantage of this refinement is that good mechanical anchorage with a high level of surface profile trueness, good insulation and good heat transmission between the laminates (7) and the commutator carrier (2, 3) are ensured. <IMAGE>

Title: Safety interlock for car seat belts - has microswitches in belt clasps and seat squabs to inhibit starting until belts are fastened
Inventor: BREDE HEINRICH
IPC: B60R22/48
Filed: 1977-07-05
Abstract: The safety belt clasps are fitted with microswitches to sense if the belts are fitted and to inhibit the engine starting circuit and ignition if they are not. The passenger switch is connected into a circuit incorporating a squab switch to bypass the clasp switch when the seat is not occupied. The passenger, when sitting on the seat, operates the squab switch which normally shorts out the passenger clasp switch, so that the clasp switch is activated. The system can be fitted to any vehicle and ensures that the meat belts have to be fitted in order to start the vehicle.

Title: HV output amplifier with rapid response - has control on LV side of transformers
Inventor: LECHNER ROBERT DIPL ING
IPC: H02M3/42
Filed: 1977-07-19
Abstract: The proposed amplifier is intended for use as a replacement for units employing vacuum tubes or transistors connected in cascade. It comprises two separate transformers (Tr1, Tr2) 180 deg. phase displaced and fed from a low voltage power amplifier (VL). A follower switch (r) changes the supply from a low voltage power amplifier (VL). A follower switch (r) changes the supply from one transformer to the other at a rate governed by a pulse generator (P). The hv output of each winding is connected via a suitable diode (D1, D2) to a common output terminal and also to a common loading resistor (R1, R2). During the non-conducting period of the transformer its primary winding is clamped by a negative bias voltage (UZ1, UZ2). The rapid control is provided by the power amplifier (VL). No smoothing is required as the built in overlap between the transformers ensures continuous voltage at the output terminals.

Title: IC engine governor oscillation suppressor - involves rod in governor housing located between fixed stop and plunger causing it to bend, using AC magnet
Inventor: HENKEL DIETMAR ING GRAD
IPC: F02D29/06
Filed: 1978-01-12
Abstract: The unit is for the suppression of governor oscillations in speed-governed diesel engines, and particularly takes the form of a mechanical brake which damps and influences the control rod. Such a rod (2) passes through the upper area of the governor housing (1), and is guided between a fixed stop (3) and a crossways displaceable plunger (4). The plunger (4), with the production of a frictional force, can be pressed against the control rod (2) so that the cross-bending of the latter (2) produces an increased or decreased gap (5) between it and the fixed stop (3). The extent of the bending forces is variable through the excitation or otherwise of an A. C. magnet (8).

Title: Aerial thrust technique without vibration or noise - uses selective transistor switching to produce interaction of molecules with half screened aerial
Inventor: DRZISGA HILARIUS
IPC: H01Q9/30
Filed: 1978-07-22
Abstract: The circular aerial rod (1) is insulated around half its perimeter, the insulated side butting against a screened enclosure containing an insulated conductor (4) at earth potential. At one end (10) a generator (15) is connected between aerial and conductor, and at the other (11) a transistor switch (12, 13) and non-reflecting resistor (14). By selective transistor switching during positive and negative half cycles the molecules, typically water vapour, are polarised, accelerated towards the aerial and then deflected round it. The interaction of molecules with the aerial produces thrust without noise or vibration.

Title: Remote height adjustment for bicycle saddle - includes sprung mount and remote release catch
Inventor: RUDOLPH ARTHUR ING GRAD
IPC: B62K19/36
Filed: 1978-10-18
Abstract: A simple height adjustment mechanism is designed to change the height of a bicycle saddle while in motion. There is a spring loaded saddle support and a securing catch (4) to hold the support in the selected up or down position. The catch is released by applying the brake lever, to which it is linked by a cable drive. The adjustment allows the rider to set off with the saddle in the lower position, so that his feet can reach the ground. When travelling he can raise his weight from the saddle and allow it to rise to the raised position, under spring pressure. In this position he obtains an efficient drive on the pedals. Application of the brakes drops the seat to allow his feet to reach the ground.

Title: Rope and cable stranding system - applying two stranding operations with higher tension in second operation
Inventor: VOGELSBERG DIETER DIPL ING
IPC: H01B13/02
Filed: 1979-01-26
Abstract: A stranding system for ropes and cables is based on a first stranding operation by the strand catenary revolving between two pulleys, and a second stranding operation between the end pulley and a pulley situated in the direction to the die plate. This second operation is carried out at a higher tension or a raised tensile stress is applied to the rope temporarily immediately after the operation. This removes the troublesome length alterations of the core (which may cause loops) at their origin so that all wires are uniformly stressed and the length differences disappear.

Title: Domestic artificial sun tan apparatus - has elongated casing containing row of bulbs and foldable flat against wall on pivoting arm
Inventor: JENDREWSKI ALFONS
IPC: A61N5/06
Filed: 1979-03-14
Abstract: The artificial sun tan apparatus using ultra violet or infra red lamps is for wall mounting. It consists of a hollow casing (1) housing a row of bulbs (4, 5) pointing downwards mounted on a set of adjustable fittings. These include a swinging arm (2) with a pivot spindle (6, 8) each end rotating about vertical axes (8', 6'). The spindle (6) at one end secures the casing to the arm and the spindle (8) at the other end secures the arm to a bracket (3) for wall mounting. This allows the lamp casing to fold flat against the wall. The casing can fold back either to the right or to the left of the bracket. The bulbs each side of the central vertical bulb can slope downwards at an acute angle to form a flat divergent beam. The operating buttons (10) are incorporated in the wall bracket. The design is space saving and sufficiently neat for a living room. The overhead position and elongated housing give a satisfactory coverage and good location.
