Title: Pneumatic brakes for unit and trailer - with selector valve to disconnect trailer from pneumatic parking brakeekke
Inventor: GOEBEL HANS DIPL ING
IPC: B60T13/58
Filed: 1974-10-16
Abstract: The pneumatic brake system for the towing unit and trailer is fitted with a parking brake facility which is controlled by a progressive valve. This enables the parking brake to be used as an emergency brake to operate on the unit and trailer. In some countries the legislation only permits such parking brakes on the towing unit alone. The invention provides a progressively acting parking brake for the unit and trailer, with a selector valve to vent the trailer brakes when the vehicle is parked. The trailer brakes are fitted with an indicator to show if they are locked on so that the driver can operate the selector valve when leaving the vehicle, while retaining emergency braking control on unit and trailer while moving.

Title: Sediment storage in mixed water canalisation - has storage basin for rain water sediment dirt at end of part faces of drainage region
Inventor: NUSSBAUM GERT DIPL ING
IPC: E03F5/10
Filed: 1974-10-17
Abstract: Sediment storage in mixing water canalisation, especially for drainage regions remote from drainage systems where the drainage region is split into part faces. A storage basin is arranged at the end of each part face, in which the first sediment of a rain storm is stored. Following rainwater, which, it is dangerous to introduce directly into the drainage system, is passed by the store directly into the drainage system. When the rain storm is over, the stored dirty water is passed via the mixing network to the clarification plant. The splitting up of the drainage region into part faces is such that there is a likeness or similarity achieved in the sediment passage line.

Title: Telephone cable with plastics form insulation - has material formed into rings of higher density at regular intervals
Inventor: LEVACHER FRIEDRICH DR
IPC: H01B13/18
Filed: 1974-12-12
Abstract: The telephone cable uses insulation made from a plastics foam material. The cable consists of several strands with an outer metallic sheath with the plastics foam insulation surrounding the internal leads. The insulation (2) is made such that the desnity of the material is higher at regular intervals (3). The positions where the material density is higher have the same external diameter as the rest of the insulation. This is achieved by heating the plastics insulation in the positions of increased density and compressing it to the original thickness. The metallic sheathing is then applied onto the cable. This cable has low dielectric losses.

Title: Ice glider with pivoted skis - has steering provided by user shifting weight and tilting mast
Inventor: DIEGELMANN JOACHIM
IPC: B62B15/00
Filed: 1976-02-24
Abstract: The ice glider has a simple boad deck on which the mast is secured by a universal joint.

Title: Self-cleaning filter for water circulating through equipment - is moved from inlet to outlet passage to be flushed
Inventor: SCHARF FRIEDRICH DIPL PHYS DR
IPC: B01D33/00
Filed: 1976-04-15
Abstract: The filter through which contaminated, esp. river water is pumped to be cleaned before being circulated through an installation such as a cooling system or a heat pump, etc., is cleared of the particles of dirt deposited on a section of its surface, continuously or intermittently. That section of the filter with the deposited particles of dirt, is moved from the feed duct into a drain duct isolated from the feed duct, and the cleansed water, after passing through the heat exchanger, flushes through the filter in the reverse direction. The filters may be arranged to rotate continuously or intermittently, or it may have the form of a plate or web which is reciprocated from one flow path to the other. Continual stoppages for maintenance, are not necessary with a self-cleaning filter.

Title: Large ratio reduction gear unit - has toothed plate wheel inclined to shaft axes and meshing with crown wheel
Inventor: MUELLERSCHOEN JUERGEN
IPC: F16H1/32
Filed: 1976-05-05
Abstract: The reduction gear unit comprises a toothed plate wheel in bearings on an axis inclined to those of the two shafts. This meshes with a crown gearwheel and has one tooth more or less than the latter. There can be a stationary supporting gear ring coaxial to and enclosing the gearwheel. This has the same number of teeth as the plate wheel and prevents it from rotating. Alternatively the plate wheel can be prevented from turning by a stationary spring component, typically a plate spring. The design gives a large reduction ratio.

Title: Locking device for self cleaning oven door - is operated by bimetal strip and thermostatically controlled blocking motor
Inventor: HELLMANN DONALD
IPC: F24C15/02
Filed: 1976-05-13
Abstract: The door (2) of an oven (51) is locked shut during the high temperature cleaning process. The door has a bar (91) on its back in which there is a slot (912). A bimetal strip (94) receives heat from the inside of the oven through a conducting pin (942) in the top of the oven. A hook (941) on the end of the bimetal strip engages in the slot (912) in the bar on the back of the door and prevents the door opening. A thermostatically controlled motor (96) drives a camshaft (961) which depresses a pin (943) belos a predetermined temperature. The pin deflects the bimetal strip and thus prevents the hook on its end locking the door the predetermined temperature.
