Patent DE-2905611-A1 (DE)
Title: Camera pistol grip with remote control socket - has internal battery power supply, hinged cover over external power supply and release control sockets
Inventor: ROTH JOHANN ING GRAD
IPC: G03B17/38
Filed: 1979-02-14
Abstract: The camera, primarily a cine camera, has the control switching circuitry located in the piston grip to facilitate camera switched trigger operation and easy connection of remote release and power supply. The pistol grip contains a battery supply, to power the camera exposure measuring and drive circuits, but this is only made operational if the pistol grip is extended into its working position thereby making a master switch circuit (5, 11) so that the pistol grip release button (6) will run the camera. If the piston grip is not extended into its working position a cover plate (10) on the grip (3) can be lifted, it is hinged (10), to uncover the remote power supply (7, 7.1, 7.2) and remote shutter release (8, 9) connections. The remote operate mode preserves the internal battery power supply of the camera.

Title: Solar energy heated hot water system - has two parallel pipe branches with collectors, at whose outlets are temp. sensors and electrically controlled valves
Inventor: MUELLEJANS HEINRICH
IPC: F24D17/02
Filed: 1979-03-27
Abstract: The system has a circuit, comprising a collector and a heat exchanger in an electrically heated water storage tank. A circulation pump drives a heat medium through the circuit with parallel branches containing several collectors, or their sections. In each branch is provided a collector temp. sensor (22) and an electrically controlled valve (24) at the output of each collector section. A further reference temp. sensor (40) is provided at the storage tank. The circulation pump (20) is controlled by a temp. comparison circuit, being switched on when temp. difference between the reference sensor and one collector sensor has exceeded a preset value. The comparison circuit opens at least the electrically controlled valve in that branch, where the collector outlet temp. difference is highest. The circuit pref. has several adjustable comparators (42, 42') whose outputs are supplied to a valve controlling relay via an amplifier (43).

Title: Concrete slab butt joint seal - by plastic filler material in recesses and seal rings
IPC: E02D29/16
Filed: 1979-05-07
Abstract: Butt joints between prefabricated concrete slabs with a plastic lining on their surfaces exposed to any corrosive attack are provided at every butt joint immediately adjacent to the plastic lining with a recess. Both recesses are filled out with an plastic material which can be cast or applied by spatula and which adheres well to the plastic slab lining, usually consisting of PVC. An elastic sealing element is compressed enough to create a tight joint with the plastic filler material. This protects the concrete end faces of slabs even when they are slightly offset against each other.

Title: Heat operated fluid pump - has flow between equaliser tanks controlled by expanding fluid vaporised by hotter pumped fluid
Inventor: ALBRICH HERMANN PROF DIPL ING
IPC: F04B17/00
Filed: 1979-07-28
Abstract: The fluid pumping system using the energy of a medium to act as a thermal engine, has a resilient reservoir (6) containing a refrigeration fluid which is vaporised so that the reservoir is expanded by its pressure so that the vapour is forced past a valve (3) into a tube (2) forming a connection to a chamber (1). A fluid entry valve (9) in a tank (4) around the reservoir is closed and an ejector nozzle (7) the other side discharges fluid, after this has caused the first fluid to expand. The control valve (3) is now opened, and the fluid passes into the reservoir which is now at a lower temperature, and condensation takes place. The second fluid, which is at a higher temperature can pass through the entry valve, to begin the cycle again.

Title: Dimming relay for vehicle - dims or dips lights at moment they are switched on, using mechanical or electronic device
Inventor: GOETZ ROBERT
IPC: B60Q1/14
Filed: 1980-02-11
Abstract: The dimming or dipping relay dims or dips the vehicle's lights at the moment when they are switched on. The driver no longer needs to monitor the switch state of his lights when forced to turn them on during the day due to the presence of fog or on entry to a tunnel. The relay also switches to 'dim' when the lights are switched briefly off and on again in order to avoid the driver having to monitor the lights and take his mind off the road.

IPC: B65H75/28
Filed: 1980-06-20
Abstract: The shielded arbor is provided at its front end with a thread draw-in device (8, 8a, 12) in order, after completion of the balling operation, to bring the thread which is guided to this arbor end and then severed into the ball interior during take-off of the ball from the closed arbor. The thread draw-in device contains a crown (8) which is formed onto the end of the support sleeve (1) and has teeth (8a) which terminate in a point and are in each case diametrically opposite a tooth gap. Radially inwardly directed catch hooks (8b) start from the points of these teeth (8a), which catch hooks extend approximately to the centre and bridge the thread which is located in its end position between two gaps. In order to make possible reliable catching, even of highly elastic yarns, the crown (8) is provided with a central drop-shaped point (12) which is seated on an axially movable rod (13) and, when the shielded arbor is opened, releases the central passage between the catch hooks (8b). <IMAGE>

Title: Reel seat for fishing rod - has tubular body with sleeve around rod and threaded retaining ring
Inventor: OHMURA RYUICHI
IPC: A01K87/06
Filed: 1980-08-13
Abstract: The seat for a reel on a fishing rod comprises a tubular body (1) for mounting on the fishing rod (B). A fixed sleeve (2) is fixed against a collar (5) and a slidable sleeve (3) is engaged with a threaded ring (6) which is threadably mounted on threads (7) of the body. A key way (4) prevents rotation of the sleeve but allows axial sliding. The sleeve has a portion extending under a portion of the ring and the portions have cooperating profiles which lock the sleeve against axial movement relative to the ring. These allow rotation of the ring relative to the sleeve to be pushed into the locked position under the extending portion of the ring. The sleeve has a tapered surface at its end to facilitate coupling of the sleeve to the ring.
