Title: Optical frequency displacement of coherent light - uses acousto-optical modulators based on Debey-Sears effect
Inventor: LANZ OTTO DIPL ING
IPC: G02F1/11
Filed: 1974-11-09
Abstract: Two or more modulators (1, 2) of the same type are optically connected in series, they are driven according to the Bragg principle. The modulators (1, 2) are supplied by generators (3, 4) with a variable frequency (f1, f2). They are arranged in such a manner relative to the direction of incident light that one modulator (1) effects a frequency displacement in one direction an and the other modulator (2) in the opposite direction. The modulators (1, 2) are arranged relative to the direction of incident light, so that both modulators effect a frequency displacement in the same direction. The generators (3, 4) which supply the modulators (1, 2) have the same output frequency (f1=f2).

Title: Heating vessel for liq with several heaters - has corrosion resistant glass or ceramic spacers forming flanged concave base over heating element(s)
IPC: H05B3/26
Filed: 1974-11-29
Abstract: The liquid heating or storage vessel uses glass, glass-ceramic, or ceramic material to transfer heat from the heating element(s) to the liquid. The glass or ceramic material is highly resistant to corrosion and therefore increases the life of the heater. The heating element (6) is pressed against the surface of a concave glass or ceramic base (2) by insulating material (4). The concave base is flanged and seals to the bottom of the container (1) holding the liquid. A flat base plate (5) bolts to the container and presses the insulating material against the element. The element may also be bonded to, or fused into, the concave base.

Title: Continuous prodn. and filling of blow moulded bottles - using a system contg. two alter-alternating moulds with small gap between
Inventor: NAUMANN WILLI
IPC: B29C49/34
Filed: 1975-01-24
Abstract: An appts. for the continuous prodn., filling and closure of containers, esp. bottles made from a continuous thermoplastics tube comprises a combined extruding, blowing and filling head; beneath this head, half-moulds receive the hot, soft extruded tube, from it by blow moulding from the head and travel downwards with the filled bottle which is then sealed as the two half-moulds above closes to form the next bottle. The half-moulds are brought up to the blowing head by a frame and continuously revolving spindles, and by two lifting, mould-closing and mould-opening element assemblies. The upper half-mould close onto the blank for blow moulding and are held close by a spindle. The other pair of half-moulds move on the vertical members to the new position, and the succession of filled bottles is moved downwards. In this position, the uppermost bottle is being filled, the next bottle below it (I), which has already been filled, is being sealed in the closure of the upper mould, while the further, previous bottle, still attached to (I) by a ligament, is ready for cutting off and discharge onto the removal conveyor. In the next stage, the mould travels downwards and the lower half-moulds travel upwards to take over the next blank.

Title: Expanding reaming tool with two groups of cutters - uses single expander block instead of multiple expander block and has correspondingly short cutters
IPC: B24B33/08
Filed: 1975-02-14
Abstract: Radial slots (34) in the cylindrical expander block accept sliders (16, 17) which project centrally from the backs of the cutters (18, 19). Each slot deepens progressively from one end of the expander block towards the other, diametrically opposite slots deepening oppositely, so that their floors (31, 32) are parallel. the sliders are cut back correspondingly (23). When the expander block is pushed downwards, the bottoms of one set of slots (31) push the corresponding set of cutters (14) out into a cutting position, the other finer set (15) remaining retracted; and vice versa when the expander block is pulled upwards. The expander block as in 2450686 consists of two or more units of the type described; now, with a single unit, shorther cutters can be used.

Title: Numerical data signal transmission via coupling device - improved method of transmitting data
Inventor: WINTZER KLAUS
IPC: H04Q11/04
Filed: 1975-05-22
Abstract: Numerical data signals can be delivered by signal transmitters in any time succession simultaneously with a preceding address signal which indicates a determined signal receiver for the reception of the data signals, via a coupling device. The data signals of the different signal transmitters considered are separately memorised for each signal transmitter, before being routed to the coupling device. Only when in the present of a determined number of data signals coming from the signal transmitters, and the data signals and the address signal characterising the desired signal receiver, sent to the coupling device. Communication between the coupling device input, at which address and data signals are introduced, and its output, which is coupled to the desired output signal, is established due to the address signal considered uniquely for the duration of data signal transmission.

Title: Fuel injector feed pipe dummy - is spring steel wire whose shape is maintained after bending by series of tensioned balls and rings
Inventor: GUIDO JUERGEN DIPL ING
IPC: F02M55/02
Filed: 1976-03-22
Abstract: The fuel injector pipes between fuel injector pump and the respective injectors must all be of equal length, but owing to engine layout, show different bends. A dummy from which the respective pipes may be copied, is formed from a predetermined length of spring steel wire whose two ends are held by a tensioning clamp (2). A series of rings and balls are threaded on the wire between the tensioning clamps. Each tensioning clamp (3) consists of a threaded tube (6) able to grip the steel wire and terminate as a nipple with union nut (12) to fit the injector or pump. The threaded tube has an adjuster nut (10) which makes it possible to tension the ball and ring arrangement after the bends have been formed and so maintain the shape until it has been copied.

IPC: F02M21/12
Filed: 1976-04-17
Abstract: For the most uniform possible distribution of coal dust in a carrier air flow a screening-drum-like hollow cylinder (3) having a plurality of perforations (8), which is driven at constant speed, is provided in a housing (2). At the same time the hollow cylinder (3) moves through a fuel storage chamber (12) provided in the housing (2), the perforations (8) in the hollow cylinder (3) filling with coal dust. Following the fuel storage chamber (12) in the direction of rotation of the hollow cylinder (3) a suspension air feed system (4) is arranged, which has a duct (14) opening out on the inside of the hollow cylinder (3). On the outside of the hollow cylinder (3) a discharge duct (15) for the suspension, which forms when the perforations (8) filled with coal dust pass below the duct (14), is provided in the housing (2). In the process the coal dust present in the perforations (8) is blown out of the perforations (8) by the air fed by way of the duct (14) and is then uniformly distributed in the discharge duct (15). Additional air is then added from the ejector-shaped ducts (17). <IMAGE>

Title: Multicore flat insulated cable - has individual cores identified by different numbers of ribs formed in insulation
Inventor: MUENSTER GUENTHER ING GRAD
IPC: H01B7/08
Filed: 1976-10-14
Abstract: The flat cable consists of several conductors enclosed in the same insulating plastic. The coated conductors are joined by plastic webs (7) formed during the coating process.
