Title: Table tennis bat with anatomically shaped handle shells - provides extra stiffness through overlapping handle segments
Inventor: HEILOWAY JAMES V
IPC: A63B60/08
Filed: 1974-02-15
Abstract: A table tennis bat has an elliptical plate with an integral stem in the direction of the longer axis of the ellipse. This provides maximum bending stability. To each side of the stem a handle shell of anatomically correct shape is attached. To increase the stiffness of the bat, each handle shell has an integral segment which overlaps the base of the bat plate. The handle shells are hollow so that the weight of the bat is kept to a minimum. Perforations in the shells reduce the formation of perspiration. Preferably the layers making up the hollow handles are made of different kinds of woods, more preferably using maple, pine, and coto wood.

Title: Electroerosive machining tool with electrode - has advancing drives acting on tool or workpiece to move them in any of three dimensions
Inventor: LASERMANN FRANZ
IPC: B23H7/28
Filed: 1974-03-05
Abstract: The required positions of relative movement between workpiece and electrode lie on the envelope of a hemisphere. A spacial movement between electrode and workpiece depends on the direction and magnitude of a space vector whose values are preselected by the control for the advancing drives. The initial point of te space vector lies in the centre of a hemisphere while its end point moves to the envelope of this hemisphere. The required and actual values of the space vector in the control are supervised by a regulator which in its part effects the rotation of the space vector after the required position has been attained. The direction of the space vector and its rotational speed in the XY plane are adjustable according to a variable ratio.

Title: Circular saw swarf clearing wheel - consists of rollers mounted between discs which engage with the cutter teeth
Inventor: MAIER HORST
IPC: B23Q11/02
Filed: 1974-03-28
Abstract: The clearing wheel is used to remove fine swarf from the cutting face and from the hollow in between the teeth of circular saws as used for cutting steel and non ferrous metals. The clearing wheel consists of plastic rollers which are mounted on pins between discs. The rollers engage with the teeth on the circular saw and mesh with these in the same way as a pair of gear wheels. The rolers run down the cutter faces of the saw while the roller wheel is being pushed round the saw. When the roller has reached its deepest position in the gap between the cutting teeth, its direction of rotation is reversed and the roller moves out of the gap.

Title: Rectangular containers made from sheet metal - has corrugated sections made by stretching cylindrical blank on a forming tool
Inventor: KRAUTKRAEMER GUENTER
IPC: B21D51/14
Filed: 1974-04-10

Title: Rotary pison engine - exhaust and cooling medium heat is utilised to provide additional mechanical energy
Inventor: HAUN WERNER
IPC: F02B53/00
Filed: 1974-10-26
Abstract: The engine consisting of a piston guide ring rigidly fixed to a centrally positioned power transfer axis rotating inside a circular housing and containing from two up to six pistons so that by a single rotation of the axis a number of induction and expansion chambers are formed. The piston axes are connected by adjustable slots formed in plates fixed to the power transfer axis in order to be able to adjust the compression ratio corresponding to the fuel to be used (petrol, diesel, hydrogen, or gas). The pistons are free to their cylinders and moved against the guide ring by a combination of centrifugal forces and expanding gases from the lower part of the piston. The heat from the water cooling jacket is utilised in a closed circuit to provide additional mechanical energy.

Title: Passivating layer for semiconductor device - obtd. by implantation of oxygen and/or nitrogen ions in semiconductor surface
Inventor: PAMMER ERICH DIPL CHEM DR
IPC: H01L21/318
Filed: 1975-10-17
Abstract: A semiconducting device is made, where the surface of the semiconductor is exposed to O2 and/or N2 to form a passivating layer with insulating props. The novelty comprises the use of accelerated oxygen- and/or nitrogen-ions which penetrate into the semiconductor surface to form the insulating passivating layer. In one pref. process, the monocrystalline surface of the semiconductor is bombarded with the ions. In another pref. process, the monocrystalline substrate is covered with a polycrystalline layer and then subjected to ion bombardment. A commercially available ion implantation and doping appts. is pref. employed for the ion bombardment. Process is used on power transistors, MOS-devices, photodiodes etc.; and treated semiconductor can be a base for diffusion- and implantation-masks. The passivating layers is implanted in the surface which is already provided with p-n junctions and electrodes, and avoids the mechanical stresses which are produced by conventional methods of passivation, e.g. residual stress arising during cooling.

Title: Bed urinating monitor plate - is throwaway printed circuit with toy animal contours, producing alarm signal when short circuited
Inventor: MOIGNARD BARRY LIONEL
IPC: H05K1/09
Filed: 1975-11-22
Abstract: A printed electric circuit representing a toy animal, such as a koala bear or Micky Mouse, consists of an electrically conductive pattern. The latter is applied as a mixt. of a graphite soln. with printer's ink or a dye on a latex basis. This circuit is laid under the bed sheet of children or geriatric patients suffering from incontinence; any bed wettin produces an acoustic alarm and wakens the patient. This is a cheap method of producing a throw-away printed circuit. The cleaning of the expensive urine-sensitive bed foils is eliminated and the patient is not upset by having to sleep on a cold metal foil or an electronic appliance. The circuit contours appeal to children.
