Title: Preheating arrgt. for butane - hot water in immersed pipes maintains constant vapour pressure inside reservoir
IPC: F17C7/04
Filed: 1974-03-07
Abstract: The equipment heats butane contained in a reservoir, using circulating hot water or any other suitable liquid flowing through piping or copper or any other suitable metal immersed in the butane. Water circulation maintains contant vapour pressure inside the reservoir, and thus give sufficient vapourisation for external domestic or industrial use of the butane at below freezing point. Circulation of water can take place via two steel components (1), one welded to the top of the reservoir, and the other movable one secured to the first by four screws. Two metal pipes (2) pass through the steel components, and pipe length and diameter varies with reservoir capacity. The pipes are immersed in the butane and the water flows through them.

Title: Static frequency converter for reactive power supplies - has generator detecting current quadrature and controlling phase delay
IPC: H02J3/18
Filed: 1975-07-22
Abstract: The static frequency converter uses natural switching and is designed so that the input reactive current may be controlled independently of the output current phase and amplitude. The design is aimed particularly at improving the power factor in machine and arc furnace applications. The three phase thyristor based system is controlled from a signal generator detecting the state of the input and generating a signal as a function of this state. A circuit providing the control itself responds to the input from the pulse generator and controls the firing of the thyristor groups such that the circulating current amplitude maintains a phase retard of the input in quadrative current relative to some required value.

Title: Continuous mixer for preparing cement slurry for use in wells - in which cement is entrained in angularly adjustable flat jet of carrier liq.
Inventor: MAMVRIISKY A S
IPC: E21B33/13
Filed: 1975-09-04
Abstract: A mixer for preparing a controlled density cement slurry for use in e.g. oil and gas wells is claimed. Dry cement is supplied in a first direction to a mixing chamber while a flat jet of carrier liq. is directed through the chamber in a direction normal to the first direction from a nozzle to an aligned outlet part of the chamber, the jet intersecting the incoming stream of cement.

Title: Electrically operated disc brake - has mechanical release with seal passing through housing cover
Inventor: ROGGEMANS PIERRE
IPC: H02K7/102
Filed: 1975-09-24
Abstract: This disc brake is mounted on the end of a shaft in a water-tight housing. The rotating disc (6) with brake linings on either face is mounted on the drive shaft. The pressure pads that give the braking effect are mounted within the housing and are held in the braking mode by pressure springs (11).
