Title: Ultra violet radiation water treatment unit - for sterilising water, esp. useful to swimming pools
Inventor: SAALMANN GERHARD
IPC: C02F1/32
Filed: 1973-09-22
Abstract: A unit for sterilising water, consists of two concentric cylinders and sealed at both ends w. r. t. each other. Water flows through a feed-pipe set tangentially at the top of the water cylinder into the annulus contg. a number of ultraviolet ray generators for effecting sterilisation of water.

Title: Induction machine laminated rotor - has squirrel-cage bars separated by refractory insulating plates in rotor slots
Inventor: SABEV TODOR DIPL ING
IPC: H02K17/16
Filed: 1973-02-05
Abstract: The laminated rotor for induction machines has slots set radially into the laminated rotor bore between the squirrel-cage bars. Heat resistant insulating plates are inserted into part of these slots to reduce undesirable currents in the rotor and therefore to keep the machine parameters constant. The insulating plates also mean that expensive, heat resistant insulation around the squirrel-cage bars, e.g. as in motors for centrifuges, is no longer required, which makes the machine cheaper to produce. The single slots may be replaced by pairs of slots, so that each squirrel-cage bar is flanked by a slot containing an insulating plate. The rotor faces may be insulated.

Title: Rotary internal combustion engine - has combustion and gas exchange taking place in passages in flywheel to give compact construction
Inventor: PAPAZISSIS PASCALIS
IPC: F02C5/04
Filed: 1974-09-26
Abstract: The flywheel axle is formed as a tube (R) to allow air to enter from a separate compressor consisting of a reciprocating piston joined by a connecting rod and an eccentric to the flywheel axle.

Title: Utilisation of heat in the earth - by drilling cavity in heat-conductive rock for passage of medium
Inventor: DEILMANN HANS CARL
IPC: F24J3/00
Filed: 1974-10-19
Abstract: A medium, e.g. water, is charged with the heat of the earth and heat is recovered from this medium. A cavity is tapped by drilling in a rock or mineral possessing high thermal conductivity. The medium passed in a closed cycle through the drilling and the cavity. The method is applied particularly to mushroom-shaped rock or mineral bodies, in which a kind of flue effect is obtained, resulting in an abnormally high flow of heat from the earth. The method can be generally applied, i.e. also in places, in which volcanoes and sub-volcanoes with steam source or thermal springs are absent.

Title: Failsafe full-power hydraulic braking systems - has spring brake actuator with two hold off pistons with common output
Inventor: PAGE WILBUR MILLS
IPC: B60T13/22
Filed: 1974-12-10
Abstract: A full-power hydraulic braking system comprises two independently powered service circuits serving separate sets of brakes, a common pedal-actuated dual brake valve controlling operation of the circuits, a spring brake actuator incorporating two hold-off pistons and having a common output to the brakes or brake linkage, and a dual hand control valve for effecting controlled operation of the two sections of the actuator respectively from the two service circuits. The spring brake actuator is preferably of the non-compounding type, that is, in which the spring resisting forces derived from the two pistons are not additive, thus ensuring that the hold-off force counteracting the thrust of the spring remains unaltered should both feed lines be pressurised.
