Title: Cryoliquid produced variable low temperature device - has liquid throttled in heat insulated section at point of poor heat conductivity
Inventor: GMELIN EBERHARD DIPL PHYS DR
IPC: F25B19/00
Filed: 1974-05-02
Abstract: The cryo liquid is throttled in a heat-insulated section at a point having poor heat conductivity. At a distance from this point is produced a variable temp adjustable to values greater or equal to the boiling temp of the cryo liquid. An evaporator allows low-temp gas to be evaporated, and the refrigerating output is arranged to be collected. A regulator adjusts to a predetermined temp at the evaporating device. The supply vessel is connected to a heat-insulated section. A heat insulating flow resistor is arranged in the heat-insulated section. The heat-insulated section is sealed off by a gas-tight closure by which an evaporation chamber is defined. A heater with variable output is at a distance from the flow resistor.

Title: Moulding machine for prodn. of stack moulds - fully automatic shoot-squeeze machine for use with moulding frames
Inventor: SVACHA MIROSLAV DIPL ING
IPC: B22C11/00
Filed: 1974-05-30
Abstract: The machine consists of a track above which, on a common centreline, is a vertical cylinder, a sand-shooter, and a second vertical cylinder. The first cylinder is used to pick moulding frames, one at a time, off a stack and the frame is moved along the track under the shooter. A slide is used to move a filling frame over the moulding frame and, after filling, to move a heated squeeze-plate over the mould. A press is located underneath the track and below the shooter; this press is used to push the heated pattern-plate against the moulding-frame and up against the shooter; after shooting, the pattern-plate is lowered and the squeeze-plate moved into position; on raising the pattern-plate a second time the squeeze is obtd. The moulding-frame then moves underneath the second vertical cylinder which lowers it onto a stack of filled moulds.

Title: Tyres fed to disintegrator from revolving drum - to orient all tyres to same posn. at entry
Inventor: MUELLER ERNST AUGUST
IPC: B02C18/22
Filed: 1974-07-09
Abstract: A tyre disintegrating machine is supplied with tyres by a feed device consisting of either a conical drum rotating about a horizontal axis and diverging from inlet end to discharge end, or of a cylindrical drum having its rotational axis inclined downwards from inlet to discharge end; inside the drum area number of oblique(helical) deflectors which are so inclined that, as the drum revolves, they engage a tyre and cause it roll downwards in a generally upright posn towards the discharge end, where it leaves through an opening just inside the rim of the drum. Pref. a stationary vertical deflector plate is mounted just inside the drum adjacent to this opening and at a distance from the inside wall of the drum equal at least to a tyre thickness, thus ensuring that the tyre is correctly oriented before discharge through the opening. After discharge, the tyre rolls down an inclined channel. The width both of this channel and also of the gap between the deflector plate and inside wall of the drum are pref. adjustable to suit the different sizes of tyre. No manual operations, involving heavy labour and risk, are required. All tyres are delivered to the disintegrator in the same posn.

Title: Balanced electronic semi-conductor cross-point coupler - for telephone exchange, having two pairs of antiparallel line thyristors triggered by semiconductor photoelement
Inventor: BAECHLE ERICH DIPL PHYS
IPC: H03K17/72
Filed: 1975-01-22
Abstract: The balanced electronic semiconductor cross-point circuit for public telephone exchanges, consists of two pairs of anti-parallel thyristors connected between the subscriber circuit and the telephone line diodes. Each thyristor pair has a bi-directional semiconductor photo-element (5, 6) between the gates (G1 etc.) of its two thyristors. The photo-element triggers the thyristors such that one is on and the other off in either anti-parallel pair. The line diodes between thyristor pairs and telephone lines consist of two anti-parallel pairs, one for each line. An impedance (ZQ) is connected across the two lines between thyristor and diode circuits.

Title: Suspension sieved through revolving microsieve drum with inward flow - and internal jets to loosen solids from outside of drum
Inventor: KRUECKELS WOLFGANG DIPL ING DR
IPC: B01D33/067
Filed: 1975-02-10
Abstract: A method of separating suspended material from a liquid utilises a revolving drum microsieve, the separated suspended material being washed away. The suspension is applied onto the outer face of the drum, and the separated material is then loosened from the drum wall by a jet from a nozzle directed onto the inner face of the drum wall; the separated material then flows onto a scraper blade bearing against the outer face of the drum. In a variant, the process is carried out in two stages; first the suspension is applied onto the inside of a coarse drum, the washing jets being on the outside, then the liquid from this stage is applied onto the outside of a microsieve drum (as above) the washing jets being on the inside. An increased drum rotational speed is possibly; clogging of the sieve is delayed; changing of sieve fabric is facilitated.

Title: Double-skinned folding partition - has vertical hinged panels fitted inside with arms controlling pivoting action
Inventor: BLOMQVIST OLOF GUNNAR INGEMAR
IPC: E06B3/94
Filed: 1975-02-07
Abstract: Folding partition serving for quick partitioning-off of large rooms and creating smaller rooms for temporary use operates easily and is of a soundproof design. For the latter they usually are made double skinned. The individual panels are of considerable size, may tend to warp and the rope arrangement inside the gap has to exert the same pulling force on each panel due to uneven stretch. The present arrangement uses piano hinges to connect the individual panels and the crosswise arranged guide arms inside the gap fitted to the panels give a positive control to the pivoting movement of the panels.

Title: Continuous patenting hot steel wire leaving a rolling mill - using brief water cooling, then air cooling on a conveyor
Inventor: MARZINKEWITSCH RENE ING GRAD
IPC: C21D9/573
Filed: 1975-08-14
Abstract: Patenting comprises (a) brief water cooling to 600-820 degrees C; followed by (b) the transformation of the austenite, by cooling loops of the wire in free air while the loops are conveyed to a coil collecting station. The novelty is that in stage (b), the number of loops per unit length is altered by varying the transport speed of different sections of the conveyor. Cooling until just before the transformation point pref. occurs at high speed, and then the speed is reduced so the loops are close together, and the desired temp. is reached at the coiling station. The pref. plant uses three pyrometers controlling the speed of three sections of a conveyor. A short conveyor can be used but the cooling conditions of the wire rod can be closely controlled so the desired microstructure is obtd. in the steel rod.

Title: Optical measurement for hollow electromagnetic waveguides - arranges axis of beam from light source with intersecting lines to be perpendicular to guide flange face
Inventor: JANSSEN WALTER DR ING
IPC: G01B11/26
Filed: 1975-09-29
Abstract: An optical measurement device for cylindrical hollow conductors for electromagnetic waves is designed to reduce flange location errors w.r.t. its angle to the axis of the conductor. Deviation of the flange face from an angle perpendicular to the axis leads to losses in the conductor. A holder (3) at one end (2) of the hollow guide (1) contains a light source (4) with intersecting lines (5) at the axis so arranged that the axis of the light beam (6) is perpendicular to the flange face (2). The intersecting lines (5) are reproduced via a lens system (7) on a ground glass plate (8) at the other end of the guide. Deviation of the axial cross image (10) from the centre point (11) gives a measure of the flange misalignment.
