Title: Synchronisation control for photocopier - has movable original size indicator on flat bed and monitors in path of copy
Inventor: WASHIO TAKAJI
IPC: G03G15/28
Filed: 1973-11-13
Abstract: The original is placed on a flat bed table which reciprocates over the fixed optical system. A movable indicator on the flat bed is set to the top edge of the original and is detected by a monitor under the bed to limit the reciprocating movement of the bed. Other monitors are placed in the path of the copy to synchronise the leading edge of the copy with the leading edge of the projected image. The length of copy paper cut off the supply reel is determined by the setting of the indicator. The system ensures accurate synchronisation as well as an optimised throughput by eliminating needless scan time for smaller originals.

Title: Rotary piston internal combustion engine - has meshing geared rotors with special tooth form in combustion chamber
Inventor: MARCUS JOACHIM
IPC: F01C1/20
Filed: 1973-12-04
Abstract: The engine has a special tooth form which, combined with the positioning of inlet and outlet and the overflow effect, allow it to function as an internal combustion engine. The two piston shafts can be carried in bearings clear of the pistons themselves, and which are generously dimensioned, the drive between the shafts being via gears with no free play between the teeth, resulting in a frictionless circulation process needing no lubrication, and consequently a great reduction in the need for cooling. The gearwheel and the gear with which it meshes can have a ratio of 2:1, having straight or only slightly helical teeth, to control the compression effect in the space between them.

Abstract: Fluids, esp. aqs. effluents contaminated with radioactive matter, are purified in an installation combining evaporation and condensation equipment, the particles carried over in the vapour being precipitated in a first fluid separator, and the steam being then injected at least once, together with a cloud of finel divided water from the final distillate, into an additional fluid separator, where the acqs. particles are agglomerated. The fluid precipitated in the separators is used as the wash in the scrubbers of the vaporises, and is sprayed into the steam going into the first separator. A singl stage plant superior to known double wastage installations. With comparatively little evaporation, large quantities of waste water can be reduced to a radioactivity level of at least 10-7 ci/cbm.

Title: Boiler firing system with oxygen injection - uses injected oxygen in addition to fuel and air
Inventor: VESTER GERHARD
IPC: F23L7/00
Filed: 1974-02-04
Abstract: Oxygen is injected into the combustion chamber in order to improve utilisation of the fuel, increase the efficiency and to reduce fuel consumption and emission of toxic gases. The oxygen can be injected directly into the furnace through nozzles arranged in a circle or the oxygen can be added to the combustion air so that oxygen enriched combustion air is drawn into the furnace. Oxygen is supplied into the furnace under pressure provided in the storage cylinders. A metering pump can be used for controlling the supply of oxygen into the combustion chamber or furnace. Owing to the ready availability of the oxygen the systems using additionally injected oxygen have high efficiency and save fossil fuel.

Title: Automatically comminuting rubber tyres for scrap recovery - using means for feeding, conveying, pulverising classifying and bagging scrapped tyres
Inventor: RIEDER ALBERT
IPC: B29B17/00
Filed: 1974-04-11
Abstract: An installation for pulverising rubber tyres is fully automatic, and tyres to be processed are supplied only by vehicles (i.e. no man-handling) whilst the resulting rubber scrap powder must be carried away in sacks. Loosely and randomly unloaded tyres are automatically arranged in a vibrator and then fed to a store where they are classified. "Sluicing" devices are adapted to accept certain batches in predetermined quantities enabling subsequent stages to deal with them. Storage containers may be fed outside a machine for coarsely comminuting the tyres, dealing with several tyres simultaneously. The resulting chips are temporarily stored, the containers being emptied by opening flaps in the bottom. The coarse chips are then further comminuted into smaller particles and metallic foreign bodies removed. This may be effected magnetically, using an electromagnetised conveyor belt. The small rubber chips are pulverised using frictional discs allowing the degree of fineness of the desired powder to be adjusted. The powder is finally stored and bagged as desired.
