Title: Thermoplastics sheet conveyed from extruder to mould - by quick forward slow return motion of extruder nozzle
Inventor: HAEBERLE WILHELM
IPC: B29C48/50
Filed: 1975-12-13
Abstract: A method of conveying an extruded thermoplastics sheet from a continuously operating extruder to an intermittently operating thermoforming machine consists of(a) rapidly moving the extruder nozzle towards the thermoforming mould while the mould is open, then (b) slowly moving the nozzle away again at a velocity equal and opposite to the extrusion velocity, during the time the mould is closed.

Patent DE-2605904-A1 (DE)
Title: Low temperature carbonising furnace, esp. for shale - has two whirling hearths, reheats exchanger grit freed from residues
Inventor: ROHRBACH RUDOLF
IPC: C10B53/06
Filed: 1976-02-13
Abstract: Solid matter, esp. oil shale is carbonised at low temp. being brought into contact with a heated, abrasion resistant material in granular form. This cycled through the hearth at a temp. below that at which oxygen would be driven out from the clacium carbonate content of the shale. Before the heat transferring granules ae returned to the combustion zone, they are reheated to the ignition temp. in a whirling hearth. The carbonised residues and the heat transferring granules after leaving the carbonising zone, are introduced immediately at a regulated feed into the whirling hearth of the furnace. During the subsequent combustion of the carbonaceous matter from the carbonising zone, the granules in the whirling hearth are reheated fully to the required temp. The gas temp. and the speed of flow are adjusted so that only the fully burned carbonising residues are drawn off with the gas, and the heat transferring material, freed from ash, is lifted over the threshold of the whirling furnace into the carbonising zone. Makes it possible to effect the combustion of an oil contg. solid material in a single step. Only the energy of combustion is used to heat fully the heat transferring granules so that the maximum burning of the carbonaceous matter in the residues is achieved.

Title: Air discharge grill for air conditioning - has controlling blade moved thermostatically according to temp. of supply air
Inventor: BAUR HERBERT
IPC: F24F11/76
Filed: 1976-07-07
Abstract: The air conditioning system for a factory has a central air handling plant which delivers heated or cooled air through ducting to various outlets throughout the building. Each outlet consists of a box attached to the supply duct (13) with a discharge register having a number of adjustable blades (18). The lowest blade (20) is connected to a bimetallic coil (24) which varies the angle of the blade according to the supply air temp. The air (28) flowing off this blade deflects the main air stream (27) off the other blades so that the direction of the total air stream depends on the temp. This ensures correct air circulation at each temp. to maintain comfortable conditions without the need for manual adjustment of the registers.

Title: Boot fixing plate on cross country skis - has vertically moving levers pushed downwards by thrust on ski to prevent ski sliding backwards
Inventor: STOELZLE FRITZ
IPC: A63C7/00
Filed: 1976-09-16
Abstract: A ski binding on cross country skis (10) includes a roller plate (5) which moves between the sole of the ski boot and a pressure plate (6) on the ski surface. A fixed stop (13) restricts the sliding motion of the plate and a coil spring (4) returns it to its normal position. Hinged levers (8) on either side of the roller plate are guided by location pins (11, 12) near the bottom edge of the side faces. When the reaction force from the ski boot pushes the roller plate backwards, the hinged levers (8) protrude below the lower face of the ski. Thus when walking uphill, the skis are prevented from sliding backwards due to the protruding levers.

Abstract: The self-monitoring control system has several control channels. Each channel has an individual pressure medium source control valve and monitor valve, both connected to the source. a separate converter producing pressure signals to give a piston indication, and is connected to each valve. Individual comparators receive the signal from the control and monitor valves connected to the same source. The comparator is the only detector, to which the signals are connected to show any deviation, and to produce a fault indication signal accordingly. Switches receive the fault signal, and switch-off the faulty control channel.

Title: Thermostatic mixing valve for hot and cold water - has hollow cylindrical temp. sensor contacted by mixed flow to control valve settings
Inventor: SCHMIDT HEINZ
IPC: G05D23/13
Filed: 1977-08-05
Abstract: In a mixing valve for hot and cold water the two flows mix at one end of a hollow cylindrical temp. sensor (27). The mixed flow sweeps over both sides of the sensor but more of the hot flow passes through the inner side. Action of the thermostat moves the sensor in the sense to open or close a part of the hot flow. The outlet for the mixed flow is at the other end of the sensor. The invention improves the accuracy of temp. control esp. when using a hot mix.
