Title: Cleaning bulk materials, esp. regenerating foundry sand - using centrifugal force to impel the sand against an impact plate
Inventor: SCHEEL HANS-JOACHIM
IPC: B22C5/02
Filed: 1974-02-25
Abstract: In the cleaning of bulk substances, esp. the cleaning and regeneration of foundry sand, using a barrier in the path of material flow, the material, e.g. sand, is impelled at high velocity by centrifugal force against a stationary impact plate, a bed of the material, or a similar device and is thus broken up and cleaned by the friction on, or in, the bed. the material pref. penetrates the bed which may be rotated against the flow and a sequence of beds may be used, esp. a vertical row through which the material falls by gravity. The pref. devices use one or more impeller plates, slotted baffles, impact plate(s) and air-extn. A simple, effective device which codes not involve high cost.

Title: Railway sleeper for single or double track traffic - is made of composite, elastic material and has indentations for insertion of rails
Inventor: HACK KLAUS DIPL ING DR
IPC: E01B3/44
Filed: 1974-03-05
Abstract: The material used may be of used tyres with steel or textile reinforcement contained in them chopped up to a diameter of not more than five centimetres, and a chemical binder such as a resin.

The sleeper for single-track traffic consists of two halves, with the division between them positioned underneath the rail and assuming the function of clamp. The impact resistance between the rail and the track base-ballast or similar material, is improved by the sleeper.

Title: Volume reduction of empty containers for liquids - has plunger and tubular matrix through which compressed articles are self expelled
Inventor: STELAND GUENTER
IPC: B30B9/32
Filed: 1974-03-26
Abstract: A method to reduce the volume of the box-type container e.g. for oil or drinks etc, utilises a plunger and matrix system between which the hollow bodies to be compressed are stacked. The matrix is a hollow tube and somewhat larger than the plunger in diameter but smaller than the diameter of the boxes to be compressed. Downward movement of the plunger firstly compresses and then expels some of the box type container through the hollow tubular matrix due to the developed tensile stresses. In a preferred design the adjusting surface of the container is provided with a raised ring shaped surface.

Title: Vehicle automatic transmission fluid pump - has combined centrifugal and friction components for coupling at given speed
Inventor: BECKER BURCKHARD
IPC: B60K25/00
Filed: 1974-04-09
Abstract: The combined centrifugal, and friction coupling is used for driving a pump at approx. constant speed, for pumping oil in an automatic transmission of a motor vehicle. The shaft and the pump are coupled by friction elements which have friction surfaces and are connected to centrifugal weight which respond above a certain speed of the input shaft. When the rotating speed is increased then the sliding friction is reduced. The combined friction element and the weights are two bodies pivoted about pins against a spring force at higher speeds, so that the coupling slips at higher input speeds.

Title: Oil traces identification in heavier fluids - by detection of oil film deposited from slow side stream
Inventor: LAMBRICH KARL HEINZ DIPL CHEM
IPC: G01N33/18
Filed: 1975-05-05
Abstract: Small traces of mineral oil products can be detected in moving or static fluids at higher specific gravity than oil (specially in water) by introducing a current of the fluid into an overflow chamber at a low enough velocity to allow the separation of the oil traces. A monitor senses and measures the oil accumulation and actuates an alarm when a limit has been exceeded. The device can be easily flushed; a repetition of the alarm indicates more than an incidental spillage. It is equally suitable for static or moving water.
