Title: Wet processing, esp. washing continuous piece goods - by guiding horizontally inside chamber through separate part treatment zones
Inventor: BAEHRE GERHARD
IPC: D06B3/20
Filed: 1975-08-08
Abstract: The parent patent describes an installation for the treatment of continuously running bands of material, esp. textile piece goods, with processing fluids, either for the action of chemicals on the materials, for the application of substances such as dyestuffs, or for the washing out of matter such as superfluous treatment materials or impurities from the goods being processed. According to the type of treatment, the goods run over guide cylinders from above downwards or from below upwards, through part treatment zones in which fluids are applied to them; the zones being clearly separated from each other, in succession and arranged one above the other. Each of the part treatment zones consists of (a) a zone of brief processing with the goods running through the processing fluid; (b) a zone of combined action on the goods of the fluid and treatment by a hot gaseous medium such as steam during a long free run, a large part of which is horizontal; and (c) a zone in which the goods are effectively squeezed before they enter the next part treatment zone. In this addn., in the long stretches through which the goods run horizontally between the turning, guiding and squeezing cylinders, width holding devices are installed which act simultaneously as wiper rods for the separation of neighbouring processing zones. Gives more positive guiding of difficult to handle goods. Separates the part treatment zones more sharply.

Title: Differential piston to operate trailer brake valve with failsafe brake - has emergency brake if reservoir pressure drops to predetermined value
Inventor: VOLLMER OTTO
IPC: B60T15/18
Filed: 1975-11-14
Abstract: The dual circuit trailer pneumatic brakes are coupled to the supply line by a double valve with a pressure control piston which monitors the pressure level in the supply line and isolates the trailer brakes if the supply line breaks. The valve then applies the trailer brakes if the trailer reservoir level drops to a set value. The control valve has a differential piston whose ratio of piston areas corresponds to the set fraction of the reservoir pressure at which the emergency brakes are applied. The system is thus independent of the inital pressure in the reservoir, and does not require the reservoir pressure to reach a low level before braking operates.
Patent DE-2554577-A1 (DE)
Title: Self drilling blind rivet - consists of shaft in sleeve with fracture groove and drill bit end
Inventor: KNOCHE ALFONS

Title: Hinged bridge plate for belt conveyor exit - has containers directed onto either of two levels for stacking according to sensor output
Inventor: ROUCHAL JOSEF DIPL ING
IPC: B65G57/03
Filed: 1975-12-23
Abstract: A horizontal conveyor belt carries cube shaped objects towards a hinged bridge plate at the end of the conveyor. The plate pivots about a horizontal axis and is able to direct the objects from the conveyor onto two moving belt platforms which are located above each other. When the two belts are driven together, the two objects are moved ahead until the object from the top belt is placed on top of the lower object. The stacked objects are then moved forwards by the exit conveyor. Sensors detect the positions of the objects during the transfer, thus they produce the control signals for the conveyor drives and the bridge plate operation.
