Title: Rotary capacitor stack of stator and rotor electrodes - has metal plated spacers giving higher surface specific resistance than spacer core
Inventor: MATSUWAKE YOSHIO
IPC: H01G5/06
Filed: 1973-04-05
Abstract: The rotary capacitor with spacers between the stack stator and rotor electrodes which protrude radially from the fastening axis is produced by metal-plating the spacers, the specific resistance of the plating being higher than that of the highly conductive spacer metal core. Each electrode stack (11, 12) is then firmly pressed together and the contact surfaces between the spacers are heated until the metal plating is melted on the contact surfaces. The melted metal provides a firm connection between the electrodes and the spacers. After cooling down the rotor core (12) is secured on the rotor shaft (7), while the stator core (11) is secured to a stationary stator rod. Preferably the heating is provided by a resistance welding machine.

Title: Control circuit for steering tracked vehicles - in which the tracks are driven by separate hydraulic motors, for small turning circle
Inventor: NIKOLAUS HEINRICH DR-ING DR
IPC: B62D11/18
Filed: 1973-10-08
Abstract: The hydraulic motors are fed from variable pumps controlled by pressure cylinders. Forward/reverse valves can be operated separately to give both tracks forward motion or one forward and one backward. The control circuit is fed from the pump. By variation of the by-pass valve the pressure in the circuit is controllable, the greater the pressure the lower the motor speeds. Throttle valves are arranged on by-pass connections between the ends of the control cylinders. The outlet pressures from the throttled circuits are controlled by two pressure control valves; both operated in the same sense for speed control, in opposite senses for steering control. The aim is to provide sensitive, shock free steering control and by driving one track forward and the other backward to turn in the smallest possible space.

Title: Thin transparent layer thickness and index of refraction determination - using interference between lights reflected from two surfaces
Inventor: NEIDIG ARNO DIPL PHYS DR
IPC: G01N21/45
Filed: 1974-10-10
Abstract: The thin, transparent layer is applied on a substrate, and the light used is monochromatic. The substrate is firmly held and irradiated by two monochromatic light rays whose angles of incidence are different. Each light ray is reflected by the surface of the transparent layer and by the substrate surface, and split in two parallel light rays. Each pair of rays is focussed on a point, and the interference maxima and minima produced there are optically detected and recorded. Thickness and index of refraction of the layer is determined from these data and from the interference conditions.
