Title: Securing device between broom head and handle - spider holding screw in hole in broom head spreads on handle insertion
Inventor: REICH KARL HEINZ
IPC: B25G3/28
Filed: 1974-06-22
Abstract: The broom handle (1) which is tapered to fit into a hole in the broom head (3), carries an insert (2) with a coarse external screw thread. Into the hole in the broom head is placed a connecting screw (4) supported by a conical washer (6) permanently attached to it. Over this is placed a cup-shaped spider (5), and when the broom handle is screwed down over the screw, the spider is compressed, and pointed arms extending from it are embedded in the bottom of the hole, retaining the screw (4) giving a permanent joint. A small peg extending up from the washer engages between two of the pointed arms, so that the washer cannot rotate.

Title: Pipeline system with low thermal contraction - esp. for carrying liquefied natural gas at low temps
Inventor: SPARLING JOSEPH T
IPC: F16L59/14
Filed: 1974-06-29
Abstract: The pipeline system has a first inner pipe and a second, outer, concentric pipe with a ring shaped space between them. A number load-transmitting elements are arranged in the annular space, each of which is attached at one end to the inner pipe and at the other end to the outer pipe and is arranged so that the inner pipe is attached to the outer pipe. Each element is in tension so that a compressive load is applied to the outer pipe by the inner pipe. The outer and inner pipes are thermally insulated to reduce the exchange of heat between them. Movement due to thermal expansion and contraction is small.

Title: Resistor or inductor winding parts removal method - for winding parts beyond terminal
Inventor: HOER THEODOR
IPC: H01C17/28
Filed: 1974-12-03
Abstract: A resistor or inductor has a former of any cross-section and any shape, on which the insulated winding is accurately placed, with the winding ends electrically and mechanically connected to the terminals. The end of a winding extending beyond the terminal is firmly mechanically connected to an auxiliary element which is in no way connected with the terminals. An insulating layer placed between the winding and the auxiliary element adheres more strongly to the latter than to the winding wire, so that when this auxiliary element is rotated about its contact point with the resistor winding and at right angles to the component axis, the whole winding under the element is torn up and stripped from the former surface. When the auxiliary element is removed from the component, all turns as far as the terminal outer edge are lifted and cut off.

Title: Headlamp cleaning system - using vibrating mesh over lens operating all the time ignition is on
Inventor: KOENIG KARL
IPC: B60S1/60
Filed: 1974-12-05
Abstract: Each headlamp is covered with a flexible web stretched between simple transducers and mounting points. The transducers are powered from the ignition system, with the amplitude regulated to coincide with the mesh size. This provides a good mechanical cleaning action for the headlamp lenses without any complicated mechanical linkage, and without requiring any cleaning fluid. The system operates automatically all the time the ignition is switched on, and thus requires no special controls for the driver. It is simple and economical to fit to existing vehicles.

Title: Reversible axial flow ventilation fan - has pivoted blades which swing through 180degrees when rotation is reversed
IPC: F04D29/36
Filed: 1975-05-28
Abstract: The fan has a wheel (1) which carries radially projecting profiled blades (3). Each blade has a base (7) which is wider than the profiled working part of the blade (3) and is attached to the wheel by a pin (5). The pin (5) is slightly out of line with the plane of the working part of the blade. The blade carries a weight (9) which may be attached to the back of the blade or integral with the blade. When the fan rotates in one direction (A) the blades propel air in one direction (B). When the rotation is reversed the moment of the weight (9) about the pin (5) causes the blade to swing through 180 deg. and it then propels air in the opposite direction with equal efficiency.
