Title: Continuously cast block machining equipment - has peeling machine with clamping bodies delivering between face milling machines
Inventor: LINDEMANN WOLFGANG DIPL PHYS D
IPC: B23C3/14
Filed: 1977-03-21
Abstract: The equipment which machines continuously cast blocks of relatively short length on all sides by peeling and by milling the end faces flat, has a peeling machine with guides immediately before and behind the rotary peeling head. Each consists of two pairs of clamping bodies in different radial planes. They can be moved in relation to each other alternately to and fro, so that one pair moves end to end in the feed direction. Parallel to and offset from the peeling machine are two face milling machines, with controlled movement of their tungsten carbide tools to and from each other. The blocks are fed to the peeling machine via a loading table at right angles to its axis, having a reciprocating slide. The peeled blocks pass via a discharge trough and a feed table at right angles to it to a further reciprocating slide, delivering them to a clamping mechanism. The latter moves parallel to the loading table, and to a parallel discharge table, between the milling tools, and back again when machining is complete.

Title: Opto-electronic switching device for telephone exchanges - consists of ferro-electric ceramic wafer with matrix electrodes to apply field
Inventor: DOST WILLIBALD ING GRAD
IPC: H04Q3/52
Filed: 1977-03-24
Abstract: A matrix switching element, particularly for telephone exchanges comprises a wafer (1) of transparent ferro-electric material having thin transparent strip electrodes. The horizontal electrode (2) corresponds to the lines of the usual mechanical coupling system and the vertical strips (3) to the columns. In front of the columns is a polariser (4) and after the lines is an analyser (5) to increase contrast. Each crossing point has a light-emiting diode (6) and a phototransistor (7) associated therewith. On application of an electric field between the electrode (2, 3) the ferroelectric ceramic at the respective crossing point is rendered opaque, thus cutting off the transmission of light between the diode and transistor.

Title: Flow reversing afterburner with aerodynamic by=pass arrangements - has entry to reversal zone restricted and longer gas remixing path
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N3/26
Filed: 1977-04-07
Abstract: The flow reversing afterburner with a aerodynamic bypass arrangements is basically as in the main patent with exhaust entering the mixing chamber (30) through rows of angled tubes (5, 6). Air enters through perforations (15, 17) in the preheating (16) and mixing chamber boundaries. The holes (12) of form mixture flow into the post-combustion zone (14) without passing through the flow reversal zone (10, 11) passing through the flow reversal wall portion opposite the duct (33) linking the two zones. Also, there is a flow restrictor (8) at entry to the reversal zone. Lagging (9) behind the surface (24) on which the bypassed mixture impinges reduces heat loss. For additional assurance of continued combustion there can be an extra spark gap (18) under the flow restrictor.

Title: Combustion driven water cannon - has floating ejecting piston driven by fuel in chamber ignited by adiabatic compression
Inventor: MALBURG WERNER
IPC: F02B71/04
Filed: 1977-05-20
Abstract: The water cannon (2) comprises a cylinder bore (6) in which a floating piston (8) is movable between a chamber (12) for the liquid and a combustion chamber (28). The piston is driven by ignition of fuel in the combustion chamber and expels a high-velocity jet from the chamber which is filled before ignition takes place. Ignition is initiated by heat generated by adiabatic compression in the combustion chamber. The fuel charge may contain combustion gas residue which has not been exhausted. It may contain a gaseous fuel component and/or a liquid fuel component. The compression may be produced by a separate ignition piston (10) whilst the ejectors piston remains stationary.

Title: Mangle spring mfg. - uses a triple roller assembly to apply bending and pressure forces on spring strip
Inventor: SCHMITZ WERNER E
IPC: D06F67/00
Filed: 1977-09-06
Abstract: In the mfr. of springs to adjust the height of the feed of an ironing or mangling machine in relation to the trough, in the form of a foot section and an angled upwards leg to an upper section parallel to the foot, the spring is shaped from a spring band strip. The spring band is passed through a triple-roller assembly to apply simultaneous bending and pressure forces.

Title: Gravel screening system - using combined loading and screening using bucket fitted with screens
Inventor: LEINONEN HEIMO JUHA
IPC: B07B1/28
Filed: 1977-09-17
Abstract: In a sizing system for granular material such as gravel by screning, the screening operation can be combine with the loading operation by using a bucket, fitted with screens. The screen underflow drops to the bucket bottom, and can be emptied by opening a flap. The oversize is retained on the screen and is dumped by tipping the bucket. This saves time and equipment compared with the conventional loading by power shovel and dumping into a separate screening station.

Title: Milling system for materials of different grain sizes - has mill and sifter by=passed by fine material for delivery to separator
Inventor: FASBENDER HEINZ
IPC: B02C17/18
Filed: 1978-03-11
Abstract: The milling system for materials of different grain sizes, has corresponding bunkers (2, 3, 4) for these materials, discharging onto belt conveyors (23, 24, 25, 26). Material from the first two bunkers (2, 3) is passed through a double flap into the horizontal cylinder mill (1) followed by a pneumatic sifter (5) and a cyclone separator (6).

Title: Exhaust heated heater for vehicle - has frost and overtemperature protection valves, and water additives are not required
Inventor: SCHLEIERMACHER HERBERT
IPC: B60H1/20
Filed: 1978-07-05
Abstract: The heat exchanger for a car heater has a tank (9) fitted with control valves to ensure that the tank temperature is kept within set limits, to prevent the tank from freezing or boiling. Water is heated by a separate heat exchanger (4) around the exhaust pipe. If the temperature in the tank falls below a set level than a safety valve drains all the water into the heat exchanger which is constructed to withstand freezing expansion. Also, if the water in the tank exceeds a set amount then the flow to the heat exchanger is limited and a venting valve (16) in the top of the tank allows over pressure to be vented. The system does not require anti-freeze additives.

Abstract: In order to produce electrochromic display devices which contain a film of amorphous tungsten trioxide (WO3) as electrochromic layer, it is proposed, during the manufacture of this electrochromic layer, to set the relative ambient humidity to a value below 60 % and the vapour pressure of the water to a value below 14 mmHg. This production method ensures good electrooptical properties for the electrochromic layer and a high yield with relatively narrow fluctuation range for mass production. <IMAGE>

Title: Locking ring for chuck of small high speed drill - has spring loaded balls which create axial force on drill shank collar
Inventor: NATTEFORT FRITZ
IPC: B23B31/20
Filed: 1978-12-20
Abstract: A small high speed electric power tool has a drill with a pressed on collar. The shank of the drill fits in a chuck with spring fingers. Any tendency of the drill to slip during operation is prevented by steel balls which are held in radial holes in the housing. These balls engage slots in the collar and slots in the locking ring. The locking ring is subjected to an axial force by the disc springs which exerts a radial force on the balls. The radial force on the balls then creates an inward axial force on the collar.
