Title: Controlled humidity cooler for bakers dough - draws in external air when temperature rises for fermentation
IPC: A21C13/00
Filed: 1973-03-22
Abstract: Dough pieces are held overnight in the cooler at about 6 degrees C, ready for a raising period at about 25 degrees C. just before morning baking. As the air circulating in the chamber approaches 10 degrees C. This is signalled by a temperature sensor to a control which automatically starts to open an inlet for external fresh air to enter the chamber; the inlet is pref. a hinged plate throttle value which opens progressively to fully open at about 20 degrees C. The inflow of fresh air is used to control humidity in the chamber so that moisture does not condense on the dough pieces and spoil them. This system is simpler and cheaper than previously proposed hygrometric controls.

Title: Magnetic rotary motor - uses magnetic attraction of levers on an inclined face
IPC: H02K53/00
Filed: 1974-03-22
Abstract: This motor has a circular main body whose upper face has an inclined surface. A vertical axle shaft supports a circular rotor by suitably profiled bearings that are parallel to the inclined face. The rotor has a system of levers that are attracted by regularly spaced magnets on the descending part of the inclined face. As the levers are attracted by the magnets they press upon pistons which thrust upon a bearing that is parallel to the inclined face. This attraction and thrust create a rotary movement that is caused by magnetic attraction.

Title: Double twisting spindle has rotating yarn guide at spindle base - to block tension of yarn in the balloon
IPC: D01H7/86
Filed: 1974-07-31
Abstract: A double twisting spindle comprises a stub-spindle on which is mounted a hollow spindle carrying a yarn package so that as the stub spindle is rotated by a belt contacting a main drive pulley, the yarn passes from the package and through tension blocking device at the top of the hollow spindle and then downwardly through spindle. The yarn passes from the base of the hollow spindle through a yarn guide rotating with the stub-spindle and then upwardly to e.g. a pig-tail guide above the two spindles, so that the yarn forms a balloon around the package. The package is supported on a platform connected to the stub-spindle and is surrounded by a protection pot. Beneath the main drive pulley is provided an auxiliary pulley driven by a belt at a rotational speed slightly slower than the rotational speed of the main drive pulley. The auxiliary pulley has an inner surface provided with a gear ring with which engages a satellite gear having at its upper end a yarn guide duct through which the yarn passes between the base of the hollow spindle and the yarn guide. The tension of the yarn in the balloon is reduced thereby allowing the device to operate at higher speeds and reducing yarn breakages.

Title: Coherent control of information in hierarchy of memories - ensures optimum control of data in different speed processors
Inventor: FEAUTRIER PAUL
IPC: G06F12/0897
Filed: 1975-04-17
Abstract: The management of a hierarchy of data memories ensures optimum conditions for speed of access where memories are faster than those adjacent in the hierarchy. The slowest are used for storage of data which is not modified while the faster contain modifiable data. A processor is contained in a hierarchy of processors which are slower or faster in operation. At this level the contents of a data block are addressed and are read and written under control of a control processor with associated index. This processor communicates with processors and their index registers at other levels. Areas in the index registers and reading writing register are separately identified and addressed in order that the contents may be incremented or decremented providing timing for the appropriate processor.

Title: Buoyancy control for underwater survey equipment - with external coil pipe with piston and ballast fluid
Inventor: SVERCHKOV J S
IPC: B63G8/22
Filed: 1975-09-19
Abstract: The underwater survey equipment is fitted with a buoyancy tank which is of rigid material and with a fixed volume. A special coil is fitted around the tank, open at one end and linked to a pumping port with the other end. The pipe is connected to a reservoir, on board the ship, by a line and a pump. A movable piston in the coil separates the ballast fluid from the seawater. The system enables a rigid tank to be used, with the size of the coil selected to provide the required amount of buoyancy. The tank therefore has a long life.
