Title: Coffee percolator with upper and spare water vessel - knob on top rotates to control water feed valve from upper to lower vessel
IPC: A47J31/54
Filed: 1974-04-30
Abstract: A coffee percolator has an upper water container (1) with a lid (5) which is lifted for water to be poured inside, and has a lower vessel (3) with a draw off tap and a heating coil. A knob (6) on the lid carries a spindle (7) with a valve member (12) at the bottom which seats against a surface inside a connector (12) between the upper and lower vessels, fitting on the neck (11) of the lower vessel. When a low level (16') is reached in the lower vessel, after coffee has been drawn off, the knob is rotated and due to a threaded portion of the valve member, the latter is raised from its seat and water passes through holes (13) in the connector from the upper vessel into the lower vessel.

Title: Hydraulic safety brake - has brake cylinder actuated on full depression of brake pedal when main brake fails
IPC: B60T17/18
Filed: 1974-05-29
Abstract: The normal brake drum and shoes are employed but actuated by a separate cylinder. As soon as the normal brake has failed, due to severe fluid loss, for example, the brake pedal reaches its lowest point and, in so doing, actuates the safety brake. This it does by pressing on a finger controlled by a spring (10). There is a master cylinder (20) from which brake fluid passes via pipes (18) to the brake cylinder. When pressure is removed from the brake pedal the finger returns under the force of the spring (10) and the safety braking force is removed.

Title: Anti-stall device for hang glider - with drawlines to front parts of sail panel to alter sail angle
Inventor: GOUDA SAMY
IPC: B64C31/028
Filed: 1974-09-11
Abstract: The hang glider is controlled by a triangular frame section (8) suspended below the centre of lift of the machine. The pilot is supported by the frame and controls the flight by moving his weight on the frame. The glider is prone to stalling if the angle of the sail cloth wings falls below a critical value, w.r.t. the airstream. In order to prevent this each panel (1) is fitted with a safety line (11, 12) secured at patches (E, F) in the front parts of the panel and with the other ends tied to the triangular frame. If the glider stalls then the pilot pulls the drawstrings to alter the angle of the wing surface and lift the nose of the glider into a safer setting.

Title: Heat-insulating keg used in making yoghurt at home - which is of polyurethane sandwiched between two sheets of polystyrene
IPC: A23C9/12
Filed: 1975-07-28
Abstract: To make yoghurt, milk is heated to 50 degrees C, a ferment is added and the mixt. stirred: it must then be kept at 50 degrees C for a further 5 hrs. To make this last step practicable for the h ousewife, the invention proposes a heat-insulating cylindrical keg with a heat-insulating screw-on lid. The insulation consists of a double thickness of polystyrene with a polyurethane lining between, in the lid as well as in the keg itself. The milk mixt. goes into polystyrene pots, whose cross section is the quadrant of a circle, so that four of them fit together to go inside the keg, which holds two such sets of four. The pots have lids which fit over them, and are put on when they are taken out of the keg: the yoghurt is kept cold in the covered pots until it is required.

Patent FR-2317800-A1 (FR)
IPC: H02P5/60
Filed: 1976-07-06
Abstract: 1535816 Dynamo-electric machines SIEMENS AG 23 June 1976 [7 July 1975] 26005/76 Heading H2A In an electric drive device comprising a stator and rotor carrying a first pair of windings together forming a series commutator motor and a second pair of windings together forming an induction motor providing a lower output speed than the series motor, the supersynchronous braking torque of the induction motor is reduced when the device is running at a speed higher than the synchronous speed of the induction motor. The stator and rotor are slotted, laminated bodies, some of the slots on both stator and rotor accommodating coil sides of the windings of both motors. The induction motor secondary winding comprises coils connected in series to form a closed circuit. This closed circuit may be interrupted by a centrifugal switch at speeds above the synchronous speed of the induction motor. Alternatively the same effect can be achieved by winding the induction motor to have a higher pole number than the series motor.

Title: Injection pistol for e.g. artificial insemination - with rigid body surrounded by flexible housing
IPC: A61D19/02
Filed: 1976-07-13
Abstract: A new injection pistol for animals has a rigid tubular housing completely intersected by an axial passage. It has an external gripping head at one end, and is surrounded by a flexible housing fixed at one end by means which can be adjusted around the gripping head. At its unfixed end, the flexible housing projects beyond the rigid body and has an injection opening which is internally reinforced by an adaptor tube, the adaptor tube being transected by a passage. A plunger is slidably mounted in the axial passage of the rigid body and projects from this at the grip end. The rigid body is freely displaceable within the gripping head, and the adaptor tube is freely slidable in the flexible housing. The sections of the adaptors tube and the body are such that these two components can fit together in the axial direction. Pref. the reinforcing adaptor tube is replaceable by a massive piston head which is freely displaceable within the housing and is shaped so as to receive the end of the plunger. The injection pistol is partic. suitable for the artificial insemination of cattle. Because the adaptor tube and the body of the pistol are separate, the pistol can be used for the applications of different types of semen pellets.

Title: Curtain or flat radiator element cleaner - has pair of revolving brushes in a hood through which cleaning fluid is passed
IPC: A47L4/02
Filed: 1976-08-05
Abstract: This device for cleaning flat electrical heating elements or curtains has a pistol grip (1) on a motor case (2). The motor drives two parallel rotating brushes (3). The distance between the brush axles is such that the brush bristles grip together. A covering hood (5) is fitted over the brushes. In the hood are fitted an inlet (7) and an outlet (70) tube through which cleaning fluid is passed. A slot round the hood walls, closed by tongues of rubber, leather or plastic, allows the element etc. to be passed between the brushes for cleaning. In this way the element is cleaned on both sides simultaneously. Alternatively, a third revolving brush can be added with a corresponding slot in the hood thus allowing two lamina to be cleaned at the same time.
