Patent DE-2400245-A1 (DE)
Title: False ceiling with open U-section elements cladding - has clamping edge battens bent to press resiliently against holder assembly
IPC: E04B9/36
Filed: 1974-01-04
Abstract: The visible cladding of the false room ceiling, which may also accommodate sound-absorbent material and conceal heating pipes for surface heating, comprises elements of upwards open U-spahed cross section, bent over on two opposite, parallel sides to holding edge battens. These point outwards, and are bent from their outside edges into strips which face inwards and have a vertical springing effect, for pressing against the holder device which carries the cladding elements. The edges may also be bent upwards over the battens, with an upwards springing effect, or downwards below them with a downwards springing effect. This is esp. secure in sports halls, or similar constructions, where a ball or other object may be knocked against the ceiling cladding.

Title: Appts. adapting bicycle as home trainer - uses light folding frame which occupies very little space
Inventor: HUBER JOHANN
IPC: A63B69/16
Filed: 1974-01-04
Abstract: The adaptor frame is built from tubes which form a triangle arranged on each side of the rear wheel of the bicycle.

Title: Spring loaded disc brake with pressure operated release - can function in the event of single spring failure
Inventor: BEUTEL GERHARD
IPC: F16D55/22
Filed: 1974-11-12
Abstract: The brake disc is keyed to the shaft and is provided with slots which retain the brake blocks but permit axial movement. The inner brake ring is normally held against the brake block by the spring assembly and the outer brake ring is similarly held by the spring assembly. The brake is released by the application of pressure, either compressed air or oil, to the inlet of the cylinder. This pressure acts on the two pistons which are connected to the two brake rings respectively. Releasing the pressure actuates the brake and in the event of a spring failure the remaining spring presses the brake block against the opposite brake ring.

Title: Compressed air operated nail or dowel driver - dowels forced from horizontal chamber under handle towards piston
Inventor: FEHRS HELLMUTH
IPC: B25C1/04
Filed: 1975-04-14
Abstract: A pneumatic gun for forcing e.g. dowels into holes, has the dowels stored in a chamber and fed to the pipe through which they are driven in, under spring force. The plunger which drives the elements in is operated by an air driven piston with a rod. The handle of the driver has a pneumatic valve, and in its normal position, the top of the driving piston is connected to the compressed air supply, so that the driving rod is in the bottom position. When the valve is operated, the supply to the top of the cylinder is disconnected for a short time from the air supply, so that it can depressurise, and the piston can be pushed up by the air. When the short time has elapsed, the supply is again automatically connected to the top of the cylinder, and the piston with rod is driven down.

Title: Agitator for mill with grinding aggregate - having rotating discs with raised shoulder aligned diagonally across
Inventor: BREHM WERNER
IPC: B02C17/16
Filed: 1975-05-06
Abstract: Agitator for mill to produce dispersions of solids in liquids uses a grinding aggregate which is added, such as sand or beads of any sort, and is contained in vessel where it is mounted on a shaft. It consists of one or more disc shaped elements which has (have) a diagonal shoulder projecting upwards and downwards across the disc. The rim around the disc is raised with respect to the disc level both upwards and downwards. The shoulders can be located on only one disc, and can reduce in width from centre to edge. That on one side is radially offset from that on the other esp. by 90 degrees. Conventional mills of this kind have the problem that they cause severe abrasion of the walls but have little grinding between discs. The agitator mentioned gives much more uniform action by avoiding laminar flow between the discs. Used for preparing suspensions such as pigments, creams, chemicals, etc.
Patent DE-2522713-A1 (DE)
Title: Static inverter with limiter protecting AC amplifier - has capacitor returning excess amplitude to DC source to conserve energy
Inventor: OHBA SHUNJIRO
IPC: H02M7/538
Filed: 1975-05-20
Abstract: The static inverter has an oscillator circuit (20) supplied from the d.c. source (11) and generating an a.c. signal. This a.c. signal is amplified by an amplifier (30, 40) also supplied from the d.c. source. Protective diodes (28, 33, 34) are connected between the amplifier and the d.c. source to limit the amplitudes of a.c. signals. The protective circuitry contains a capacitor that stores the chopped off part of the a.c. signal for a short time -- thereby protecting the amplifier from damage -- and then returns it to the d.C. source to conserve energy. The advantages of the inverter are its low running and construction costs.

Title: Folding handgrip for small camera - with two hinged U-sections which store in flush setting under camera
Inventor: LERMANN PETER DIPL ING DR
IPC: G03B17/56
Filed: 1975-06-05
Abstract: The handgrip for the small camera (2) is made from two U-profile sections (4, 5) hinged together in the middle. The front section (4) is also hinged at the front edge of the camera, while the trailing edge of the second section is linked to the camera by a sliding pivot (9). In the stored position the two sections lie in a flat setting along the bottom of the camera, with the U-shapes overlapping the edges. This does not alter the size of the camera unduly and enables it to be used normally. When the two sections are slide together they link up into a hand rip, secured by ratchet clips.

Title: Noise damping machine tool slide - plastics guide block and a cylinder with piston which presses the slide against the guides
Inventor: PARVEAU LUCIEN
IPC: F16C29/10
Filed: 1975-06-09
Abstract: A machine tool slide (6) travels between guide blocks (4, 5) made from a noise damping material such as plastics or wood. A hydraulic or pneumatic cylinder (9) is mounted under the slide. The cylinder contains a piston (11) with a sealing ring (12). Compressed air or hydraulic fluid is admitted to the cylinder via a line (10) and presses the slide against the guide faces of the blocks, after the slide has been moved into its working position. The force exerted by the piston on the slide prevents its vibration under the influence of out of balance forces of the machine.
