Title: Aluminium piston for IC engines - has sawtooth profile grooves and coating of hard ferrous metal over grooves
Inventor: WACKER ERICH
IPC: F02F3/10
Filed: 1975-12-02
Abstract: The aluminium piston is furnished with a number of equidistant grooves (3) which are saw toothed in section and have the long side of the groove pointing downwards and the short side pointing upwards. The grooves are located on the trunk of the piston below the rings. The piston is covered with a coating of ferrous material applied by galvanic action to a thickness of 1 to 30 microns. The application has a composition of 0.5 to 6% metallic oxides. The effect of the grooves is to trap quantities of oil on the piston surface to improve lubrication.

Title: Passivating gallium arsenide semiconductor device - using semi-insulating gallium arsenide deposits between mesas of active gallium arsenide
Inventor: DUCHEMIN JEAN-PASCAL
IPC: H01L21/20
Filed: 1976-09-24
Abstract: Semi-conductor device is passivated by (a) erosion of a plate, consisting of a monocrystalline GaAs substrate carrying several monocrystalline layers of GaAs and a layer of a masking material, as far as the plate, so as to leave a number of mesa components having in common at least part of the substrate. Process further comprises (b) a supply of semi-insulating monocrystalline GaAs by epitoxy on those parts eroded, so as to fill the spaces between the mesa components and (c) removal of the masking material. The masking material is SiO2 or Si3N4. The GaAs supplied is made semi-insulating by doping with O2 and Cr during deposition, by means of vapour of CrO2Cl2 carried by hydrogen, or by Cr dissolved in liq. Ga. Used for the mfr. of a Gunn diode or an avalanche diode. Process avoids the need for prior masking, localised polishing or local etching using a suitable mask of a flat surfaced coated substrate to remove the passivating layer from the access electrodes.
Patent FR-2332006-A1 (FR)
IPC: A61H33/02
Filed: 1976-11-18
Abstract: Air bubble massaging devices which comprise a grid lying in the bath tub and high voltage parts outside the tub require special precautionary measures, especially for the suppression of dangerous currents over creepage distances.

Title: Propellant powder charge for firing projectiles - incorporates blocks of propellant in cylindro-toroidal configuration on light rigid structure, giving predetermined form function
Inventor: ESTERLIN JACQUES
IPC: F02K9/36
Filed: 1977-03-04
Abstract: The principla element is constituted by longitudinal rods joined by circular elements. A second set of circular elements fixed radially along the rods supports the blocks of propellent. A third set of circular elements, concentric with the first set, sets the blocks in order. The blocks are held by bands on their peripheries. Problems associated with reconciling the law of thrust and the distribution and dimensioning of perforations, and with fragility during transport of storage, are avoided. The structure allows enough passages to ensure free flow of combustion gases and to prevent local over-pressure. The charge can be transported and stored without hazard. The nature and form of the blocks are determined to give the desired form function to obtain a predetermined law of thrust as a function of time.

Title: Optical observation of rapidly moving laminated surface - is performed using TV cameras in stroboscopic lighting conditions
Inventor: TAPPE WILHELM
IPC: G01N21/89
Filed: 1977-03-24
Abstract: During high speed manufacture of laminated steel, faults due to solidification of liquid metal and due to deterioration of the cylinders are detected using TV cameras in stroboscopic lighting conditions for recording the images. A moving laminated surface (1) is illuminated by a stroboscopic luminous source (2). The reflected light and fault (9) image are captured by a TV camera (3) when an image trigger pulse is initiated. A second TV camera (5) and lighting system (4) also captures the same image area after a time interval. Both images are recorded and evaluated and superimposed in pairs according whether or not images were taken in reflected light or dispersed light.
