Title: High frequency dielectric induction well logging - determines phase shift between signals from receivers spaced above transmitter
Inventor: COX PERCY TERREL
IPC: G01V3/28
Filed: 1975-10-25
Abstract: A high-frequency electromagnetic field is produced by a probe in a well at 20-65 MHz. The total electromagnetic field is determined at a certain distance above the transmitter and a first signal is transmitted to the surface. This is repeated at a still higher location and the second signal produced from it is compared regarding phase shift in an electronic measuring and display station. This system can be used to determine simultaneously the conductivity and the dielectric constants of the soil formations around a well. This results in a clear distinction between formations impregnated with fresh water and those impregnated with mineral oil.

Title: Wind driven electrical power generator - has side passages round wheel to divert excess wind forces for stability
Inventor: KUNZ ERNST
IPC: F03D1/04
Filed: 1976-03-09
Abstract: The generator has an outer cylinder (1) which guides the wind air stream onto a three bladed propeller wheel. The cylinder has two side channels (2) which entrain a portion of the air stream and guide it over a short inner cylinder (5). This inner cylinder overlaps the outer edges of the impeller blades.

Title: Optical playback system for revolving information carrier - uses same light beam for reproduction and beam centring on track
Inventor: UENO ICHIRO
IPC: G11B7/09
Filed: 1976-08-17
Abstract: An optical play-back for information recorded on a revolving information carrier uses only a single beam of light without any diffraction grating so that the quantity of light available for reproduction is not reduced. An optical system focusses the light on the track of the revolving carrier. The reflected light reaching the detector indicates the presence or absence of indentations which is converted by the play-back circuit into a video signal. The track detectors detect any difference in the intensity of the two diffracted beams. A detector unit responds to any such difference and controls the mirror by means of an actuator to direct the light beam to the centre of the track.

Title: Running or walking shoe - has lower part of upper moulded in plastics integrally with sole
Inventor: DASSLER ARMIN A
IPC: A43B9/00
Filed: 1976-09-02
Abstract: A shoe (1) for running or walking has a sole (2) and lower part of the upper (3) integrally moulded in plastic. The plastic is preferably polyurethane of a polyester with rubber-like properties.
