Title: Curved bone pin for fractured thighbone - has flattened pinch plate at distal end facilitating tool handling
IPC: A61B17/72
Filed: 1975-08-09
Abstract: The curved bone nail is for aligning broken segments of the thigh bone on the shank region (1). The distal region (2) has a crimped part (2) flattened in one plane, and projecting out of the bone. This flattened area is a pinch plate (2) interrupting the circular nail profile. The free end of the nail extending out of the bone can be clasped by a tool so that it can be twisted. It can also be used to withdraw the nail from the bone without necessitating use of a second tool. It removes the danger of nail splitting or of tearing tissue surrounding the bone. It is also inexpensive to manufacture.

Title: Portable collector of solar energy - has upper and lower flexible sheets joined to form fluid flow passage and can be rolled up
Inventor: GRUNDMANN EDGARD ING GRAD
IPC: F24S10/70
Filed: 1975-09-11
Abstract: The collector is formed by two rectangular sheets which are joined by welding or soldering along their edges (2, 3, 4, 5). In the closed space formed between them partitions (8, 9) extend from one long side towards the other. The partitions do not extend the whole width but leave a gap at one side and alternate partitions have the gap on alternate sides of the sheets. A series of connected passages is thus formed through which water flows from an inlet (6) at one side to an outlet (7) on the other. The partitions can be integral with or welded to the inside of the upper and lower rectangular sheets. These sheets are flexible so that when the collector is empty it can be rolled up like a deflated mattress.

Title: Deep drawing stainless steel sink bowls - using two draws and tools preventing tearing of the steel sheet
Inventor: REITTER ERHARDT
IPC: B21D22/26
Filed: 1976-01-15
Abstract: Deep drawn hollow parts are made in two successive drawing operations, esp. stainless steel sinks consisting of a draining board contg. at least one sink bowl. In the first draw, the steel sheet is forced through a die plate, and the second draw produces the final shape. The first draw produces a large radius on the sink rim and an inward bulge on the sink base; then, in the second draw, the bulge provides the material needed to finish the deep sink, and the rim radius is reduced to its final size. One pref. set of tools includes a stationary punch and a die contg. an elastic insert made e.g. of polyurethane, employed in the first draw; the second draw again uses a stationary punch with an expanding sleeve used to reduce the radius on the sink rim. Similar tool sets are pref. for mfg. double-sink units, several tool sets being included in the claims. Method avoids tears during drawing, without the need for an intermediate anneal between the two drawing operations.

Title: Electricity generating plant for sailing yachts - uses battery as inertial mass to convert rolling and pitching energy into electricity
Inventor: BUCHMANN WILFRIED
IPC: F03G7/08
Filed: 1976-10-21
Abstract: A heavy mass, free to move in all three dimensions, is supported by six spring accumulators at a point as distant as possible from the centres of gravity and rotation. Movement of the mass relative to the boat, due to inertia as the boat moves is converted to electricity for storage in a battery. The system generates electricity to operate electrical and electronic equipment on sailing boats where use of internal combustion engines to drive generators is not possible. The spring accumulators drive a shaft, through free-running gear segments which in turn drives a AC generator. By adapting the system (e. g. by varying point of attachment of the springs to the gear segments) to suit the characteristic roll and pitch movements of the yacht, the output can be optimised. The heavy mass can consists of the ship's batteries (usually two 12V 100 ampere) h).

Title: Press forgings made from billets - which are fed through hot rolling mill to make bar suitable for forging machine
Inventor: KOCH FRIEDRICH-KARL
IPC: B21B15/00
Filed: 1976-12-30
Abstract: Hot or semihot pressings are made in a forging machine, starting from billets which are heated and passed through a rolling mill to obtain the required cross-section with close dimensional tolerances. The rolled bars are fed directly into the forging machine, possibly via a reheating device which adjusts the bar temp. The pref. plant incudes a billet or furnace followed by a rolling mill, which can be a 2-high or 3-high mill, straightening mill, or a pendulum rolling mill. After hot rolling, the bar passes through a heat retention tunnel to a reheating device providing a constant bar temp. as the bar enters the forging machine. The rolling mill may also include cooling zones; and the reheating device may be replaced by a cooling appts. employed to control the bar temp. Used, e.g. for press forging of relatively small parts such as bolt blanks, starting from billets which have too large a variation in dia. or cross-section to permit direct forging. The invention saves material costs.
