Title: Lightweight non-fragile roof pan-tile - partially or completely made of foamed polyurethane
Inventor: SCHIFFER FRITZ
IPC: E04D1/28
Filed: 1976-08-20
Abstract: The roof pantile, designed to combine relatively light weight and safe, easy handling with a high degree of stability, is made of foamed polyurethane - at least in the outside layer, but alternatively right through. The foamed material may have closed pores, and may have a protective coating of paint. It may be fitted with a clamp, or other anchoring element, for fixture to an underlay; this can also be in the form of a nail, for driving through a tile attachment into a roof batten. This is easily transported and handled, is less likely to break, and provides good insulation.

Abstract: 1525060 Electronic watches DAINI SEIKOSHA KK 22 Dec 1976 [29 Dec 1975] 53535/76 Heading G3T [Also in Division H1] An electrical switch comprises a rotatable cam 8 having a projection 9' engageable with a contact spring 13 and a projection 9 engageable with a cam spring 10, the arrangement being such that when the cam 8 is rotated by drive means 4 the cam spring 10 is flexed by the cam projection 9 and then moves under its own resilience to apply a rotational force to the cam 8 causing the other projection 9' to move the contact spring 13 into contact with a fixed contact 18, 19. The switch is mounted in an electronic watch having an axially movable and rotatable stem 4 mounting a clutch wheel 1 and a freely rotatable pinion 2 which meshes with a transmission wheel 5 rotatably mounted together with the cam 8 on a pin 6. A pin and slot 16, 17 lost motion mechanism is provided between the transmission wheel 5 and cam 8. When the stem 4 is axially moved to drivingly connect it to the clutch wheel 1, the clutch wheel 1 meshes with the pinion 2 whereby rotation of the stem 4 in one direction causes clockwise rotation of the cam 8 after the lost motion 16, 17 has been taken up. The cam projection 9 is moved past a projection 10a of the spring 10 to cause the latter to flex and then impart a rotational force to the cam 8 which causes the other cam projection 9 to move the contact spring 13 relative to a contact 18. If the cam 8 is rotated anti-clockwise by the stem 4, the cam projection 9' engages the cam spring 10 and the cam projection 9 moves the contact spring 13 into engagement with another fixed contact 19. The contacts 18, 19 are connected to circuits which control time correction and resetting.

Title: Evaluation circuit for secondary radar reply signals - generates signal if more than one frame coincidence pulse appears within specified time tolerance range
Inventor: HACKENBERG DIETER DIPL ING
IPC: G01S13/78
Filed: 1977-06-22
Abstract: The secondary radar reply signal evaluation circuit has a shift register with corresponding tappings for frame decoding and generation of a frame coincidence pulse, and a circuit for recognition of reply signals appearing consecutively in time and interfering with each other. Tests are made to find whether the two replies appear synchronously in the scanning pattern. In order to recognise reply signals arriving synchronously in the scanning pattern, the number of directly consecutive frame coincidence pulses is counted. If more than one frame coincidence pulse appears within a specified time tolerance range, i.e. a pseudo-frame coincidence pulse, a signal is generated signalling the presence of reply signals synchronous in the scanning pattern.

Title: Exposure control for flash gun - sets shutter time using electromagnet powered from flash gun via contact shoe
Inventor: OHMURA HIROSHI
IPC: H05B41/30
Filed: 1977-06-30
Abstract: The automatic flash gun for the camera has a set exposure speed which is controlled by fitting the gun onto the shoe. The fixed exposure speed is obtained by a lever in the shutter controls, moved by an electromagnet powered from the flash supply gun, with the connection via contacts in the shoe. The electric connection (19a) provides a failsafe internlock as opposed to a mechanical connection which can be inadvertently operated by fitting other attachments to the shoe. It also relieves the operator from manual setting of the fixed exposure speed.

Title: Appliance controlling biological effects of cosmic radiation - consists of substance having specific relative atomic mass to increase or reflect back vertical components and placed over head of subject
Inventor: WIONSEK HORST
IPC: A61B5/04
Filed: 1977-09-27
Abstract: The appliance tests and controls the biological effects of cosmic or sidereal contrary radiation. That is to say, the components of cosmic radiation that are propagated in a vertical direction and reflected back again by minerals in the earth have been known, for reasons unknown, to cause involuntary closing of the wrists and other uncontrolled movements esp. when one is a convalescent or under the effects of the weather. To increase the biological effect, thereby proving its existence, a substance having an average relative atomic mass of less than 28 units is placed over the subject's head. To diminish the effect, a substance reflecting the radiation back to earth again is used.

Title: Crosslinking silane on cable insulation - core with extruded covering passes through pressurised steam chamber before being cooled
Inventor: VOIGT HERMANN-UWE DIPL CHEM DR
IPC: B29C48/06
Filed: 1978-01-30
Abstract: Long lengths of sheathing, e.g. on electric cables, conductors, tubes, profiles etc. are produced by grafting a silane cpd. on to the molecules of basic material such as olefin polymers/mixed polymers, elastomers or rubber, using a substance which crosslinks under the influence of moisture. The sheathings are extruded in >=1 layer, opt. separately, and then immediately passed through a tube containing a humid atmosphere under pressure. Process increases the output of a continuous vulcanising plant, giving rapid penetration of sheathing by moisture. Blister formation in extrusion is minimised and the sheathing can be cooled. High stability against mechanical distortion (e.g. in high voltage cables) is achieved and e.g. high density polyethylene can be used.

Title: Sealing gaps between plastics tubular liners for concrete pipes - using temporary U=profile PVC foam sealing strip
Inventor: BREUER HANS
IPC: F16L58/10
Filed: 1978-09-02
Abstract: Process of sealing the gaps comprises fitting the plastics pipe sections into the sewer or drain pipe whilst leaving an interstice between them, and then packing it. Before the interstice filled a rubber-elastic "U"-shaped sealing profile that bears against the outside of the end of each pipe section is pushed onto the ends, thus filling the gap between adjacent pipe sections. This profile is removed again after the interstice has been packed and the space defined by the sealing profile is filled with a permanently elastic putty. The sealing profile is an extrudate made of plasticised PVC foam scrap. Useful for sewers or drain pipes.
