Patent DE-2640472-A1 (DE)
Title: Distribution system for sand bed filters - for uniform introduction of purging air and water
Inventor: FARABAUGH PATRIC
IPC: B01D24/24
Filed: 1976-09-08
Abstract: The distributor system is divided into parallel horizontal prim. and sec. passages interconnected by orifices for liq. flow and provided with outlets from the sec. passages into the bed. A further passage extends transversely w.r.t. and is connected to the prim. passages. This further passage has a connection enabling liq. to enter it and then flow into the prim. passages the liq. then flows through the interconnecting orifices into the sec. passages and enters the bed through the outlets. Novelty is that the sec. passages are located side-by-side with the primary passages and sepd. from them by inclined dividing walls halfway up which gas orifices are located. The orifices through which the liq. flows are located lower down the dividing walls. By means of introducing gas into the prim. passages, the gas flows to the bed via the gas orifices in the dividing walls and the outlets from the sec. passages. Uniform distribution of both gas and liq. are achieved even when one prim. passage is constricted. The expansion of compressed air takes place inside the distribution system and the gas enters the bed at low press. This reduces turbulence and disturbance of the bed.

Title: Bit error detector for PCM date transmission systems - uses shift register generated pseudo-random sequences to indicate transmitter or receiver error
Inventor: LEHMANN ERWIN ING GRAD
IPC: H04L25/04
Filed: 1976-09-29
Abstract: A bit error detection system for digital PCM data transmission links is based upon pseudo random test signals. A bit-wise comparison is made between a transmitted pseudo random signal sequence and a similar sequence generated in the receiver. Both pseudo random signal sequences are generated using an 'n' stage shift register with feedback coupling. Both the transmitter and receiver generate trigger signals to synchronise the transmission. The comparison process indicates whether the error originates from the transmitter or receiver.

Title: Table tennis practise wall - has adjustably angled wall section to vary return of ball to player
Inventor: HEEREN KARL-PETER
IPC: A63B69/00
Filed: 1976-12-29
Abstract: The training wall for a table tennis table consists of a board that has the width of the table. A hinge connection between the board and the two support arms allows the boad to be inclined at any angle required. When the training board is placed at a certain distance on the opposite side of the net, the tennis balls bounce back into play as if they were returned by a playing partner. When the inclination of the board is changed, the ball return is also altered, thus a variety of strokes can be practised.

Title: Electrochemical zinc and air battery cell - uses zinc spheres continuously fed via storage chamber to recharge zinc anodes when depleted
Inventor: ENRICO FERRUCCIO
IPC: H01M4/02
Filed: 1977-04-21
Abstract: Electro-chemical zinc-air cell is designed to overcome the necessity for periodic replacement of the zinc plates used in the cell as electrodes by providing an arrangement for continuous feed of zinc for the cell, the zinc being supplied to the cell in the form of spheres. This method also overcomes the shortcomings of systems using powdered zinc, which are prone to failure due to the zinc forming lumps when the cell is not actively being used. The proposed cell has net type baskets for anodes and sheet or plate-shaped nickel cathodes. The baskets are filled with the zinc balls supplied from a stocked-up storage chamber located at the top of the cell. The zinc balls located in the storage chamber are fed continuously into the basket(s) via a rotating distribution device when the potential of one of the anodes exceeds a predetermined threshold value.

Title: Reciprocating IC engine - is coupled to fluid motor which utilises heat in afterburner exhaust gases
Inventor: SCHUBERT EMIL
IPC: F02G3/02
Filed: 1977-06-08
Abstract: The engine has a double acting cylinder (13A) with two pistons (K, 13A) working in opposite directions. They are coupled to crankshafts through connecting rods. A catalytic reactor (25B) in the centre of the cylinder separates the two working spaces and pistons from each other. The first piston (K) works as a normal internal combustion engine. Its exhaust gases (25A) pass into the catalytic reactor which also receives secondary air (L) from an inlet in the centre of the cylinder. The combustion in the reactor raises the temperature of the gases which heat a plate (1H) in the end of the other half of the cylinder. The heat causes the fluid in this half of the cylinder to expand and drive the second piston (13A).

Title: Styrene!-butadiene! copolymer latex foam coating prodn. - using dispersion contg. anionic emulsifier and aminoplastics precondensate as crosslinker
Inventor: LOUIS GERD DIPL CHEM DR
IPC: D06M15/693
Filed: 1977-12-15
Abstract: Prodn. of latex foam coatings involves coating a flat substrate with a thin layer of a foamed aq. butadiene-styrene copolymer dispersion and drying the foam at 100-200 degrees C, with crosslinking with a urea- and/or melamine-HCHO precondensate. The novel feature is that the aq. dispersion used contains an anionic emulsifier and a copolymer of 40-60(wt.)% butadiene, 30-40% styrene, 5-20% alkyl acrylate, with a 4-8C, non-tert, alkyl gp., 1.5-5% 3-5C alpha, beta-monoolefinically unsatd. carboxylic acid and 0-2% (meth)acrylamide. The coating are useful on textile floor coverings. The wet foam produced from the dispersion has a more acceptable odour than that from the usual butadiene/styrene copolymer dispersions and gives more resilient coatings.

IPC: D03D47/26
Filed: 1978-01-07
Abstract: The wave-shed weaving machine has a pair of delivery rollers (20, 21) for the weft thread to be fed into the weft carriers. The delivery rollers (20, 21) of this pair of delivery rollers are connected to one another by means of a positive gear (70). Furthermore, arranged in front of the pair of delivery rollers is a controllable thread clamp which clamps the thread whenever the pair of delivery rollers does not clamp the thread, and vice versa. This design increases the accuracy of measurement of the weft-thread length to be fed into the weft carriers. <IMAGE>
