Patent DE-2505229-A1 (DE)
Inventor: JAHN EMIL
IPC: G06F1/16
Filed: 1975-02-07
Abstract: A housing lower part (1) which drops away obliquely forwards is provided with a cover (2). The front half of the cover is cut out in a stepped shape. A part (3) which complements the shape of the cover is fitted into this recess. These three parts (1, 2, 3) complement one another in such a manner that they form a box-shaped housing. The part (3) which complements the cover can be folded out forwards about rotation points located outside the housing. A connecting panel is incorporated in the front of the housing lower part for all the internal and external connections. In the transportation condition, the part (3) which can be folded out and, above said part, the cover (2) are connected to the housing lower part by means of clamping closures, which are incorporated laterally in the housing, so as to be dustproof and splashproof. The connecting panel is protected by a protective cap which can be folded out. In consequence, a compact housing is created which provides optimum protection for a terminal when it is in mobile use. <IMAGE>

Title: Fuel cell battery gas supply - with methanol cracking reactor fired by methanol for starting and recycled carbon monoxide later
Inventor: BOEHM HARALD DR PHIL
IPC: H01M8/0612
Filed: 1975-03-21
Abstract: A source of gas to feed a fuel cell battery uses methanol which is cracked in a reactor to H2 and CO; the latter is burned after the passage through the battery to recover some of the heat input for the cracking reactor. During the starting period additional methanol is supplied to the burner; on reaching normal condition this is automatically cut off but is reconnected during peak output requirements. The gas required for a fuel cell is thus supplied at a constant feed pressure. The supply is automatically adjusted to suit all fluctuations in the cell load. Environmental pollution is kept to a minimum.

Title: Electronic telephone system with digital connection matrix - is used for handling analog incoming and outgoing connections and digital code identifies called subscriber
Inventor: REED IRVING S
IPC: H04Q11/04
Filed: 1975-04-03
Abstract: The electronic telephone system has devices in the switch-through matrix to generate a digital code denoting the calling subscriber line. Further devices generate a digital code identifying the called subscriber line. A number of A/D converters are assigned one to each subscriber line wanting a connection and convert the communications signals into digital form. A number of D/A converters, similarly arranged, reconvert the signals into analog form for transmission to the called subscriber. The connection between A/D and D/A converters through the matrix takes place under the control of the two digital codes. Analog calls are thereby passed through the connection matrix in digital form.

Title: False twisting friction disks have free running guide disks - for ensuring uniformity of product when crimping thermoplastic threads
Inventor: SEIDEMANN ERNST
IPC: D02G1/08
Filed: 1975-06-19
Abstract: A device for false twisting threads by means of friction disks, esp. for crimping synthetic filaments, has at least three shafts each carrying >=1 friction disk. The thread running between the disks follows a zig-zag path, and on one of the shafts, in front of the thread inlet side friction disk, a thread guiding disk is positioned. This is larger in dia. than the friction disks. Similarly, behind the thread outlet friction disk on one of the shafts, there is a thread guiding disk which may have the same dia. as the friction disks or may be of the same size as the inlet guiding disk. The device ensures that the thread runs on to the first friction disk at the same angle as that at which it runs on to the others.

Title: Waste rubber deep freezing plant for recycling - utilises natural liquefied gas to freeze rubber for subsequent shredding
Inventor: LINDOERFER WALTER
IPC: B29B17/00
Filed: 1975-07-02
Abstract: Liquefied gases are used for deep freezing discarded rubber components for disposal purposes, e.g. large scale disposal of motor vehicle tyres. Tyres are frozen and become brittle to facilitate their shredding for recycling purposes. Used vehicle tyres are collected close to the regasification plant of the natural liquefied gas. Tyres are placed into containers after coarse mechanical shredding and the liquefied natural gas flows through these containers for regasification and in so doing freezes the rubber. Frozen rubber is shreded into finer pieces and subsequently ground into granulate or powder of required size. The liquefied natural gas must have a temperature of at least - 160 deg.C. Griding is carried out at rubber temperatures of -80 - - 100 deg.C.

Title: Electronic flowmeter transducer using comparison gas volume - converts pressure into oscillations of wire which are measured and counted
Inventor: HOFMANN DIETER DR PHIL
IPC: G01F15/04
Filed: 1976-07-28
Abstract: The electronic flowmeter transducer operates on the comparison gas principle. Comparison gas volume is closed by a suitable diaphragm (11) and converted through a spring (14) in tension of an oscillating wire (15) stretched in a transversal magnetic field. Period of its transversal mechanical fundamental oscillation is electronically measured. A correspondingly programmed nonlinear frequency digital convertor determines from flowmeter signals the total volume in the form of a bit pattern, and applies it on appearance of a conversion signal showing the conversion end, to an electronic adder (27) and an interconnected standard volume counter (29) for recording the overflows.

Title: Earthing supervisory and protection circuit - is for tripping supply if earth impedance is too high and uses loop current in relay circuit
Inventor: ULRICH HELMUT DIPL CHEM
IPC: H02H11/00
Filed: 1976-08-03
Abstract: Coupled between the line (R) and the neutral (Mp) leads is an isolating transformer (13) whose secondary winding feeds two earth electrodes (11, 12). This earth loop current is used to operate a relay (8) which closes the hold in circuit (3) of the main supply circuit breaker (2). Thus if the earth resistance rises the loop current will fall and the main circuit breaker is tripped. The circuit assists in ensuring that the earth is always of sufficiently low impedance to prevent the establishment of high voltages in the event of an earth fault in the main circuit when the latter is on. One of the earth electrodes may also be used as the main circuit earth point. Alternatively, a separate electrode, but in close proximity to the others, may be used.

Title: Screw operated waste material press - has waste container carried on two rails to present disposal bag under platen
Inventor: LEHNER FRITZ
IPC: B30B9/30
Filed: 1976-08-07
Abstract: The waste press arrangement consists of a frame on which a press plate (9) and drive is mounted. The drive consists of two screw spindles (8) driven from a motor (10). A container (13) which is mounted on rollers (28) and in which a waste disposal bag (34) is placed can be pushed under the press plate. When the waste container is pushed into the press frame, it slides on two rails (31) which lift the container so far from the floor that the container wheels are free from the floor. The force from the press is therefore taken up by the frame via the rails.
