Title: Method of anchoring traction cable on to cable car - eliminates violent swinging of cabin resulting from cable breakage
Inventor: HIRT PETER
IPC: B61B7/02
Filed: 1975-03-12
Abstract: The frame of the running gear of the cablecar has a horizontal shaft carried in bearings on which is mounted a flanged drum (6). The ends of the traction cable and return cable are wound around the drum with at least one turn in opposite directions. Each cable end then lies in the notch of a forked lug (10) on the drum and is retained by a two-piece clamp on the cable. The tendency of the drum to rotate due to unbalance of the tensions in the two cables is resisted by a friction brake. If there is an instantaneous excessive unbalance, e.g. in the case of cable breakage, the brake will slip and limit the accelerating forces on the cablecar.

Title: Converter deriving test valve proportional to PRF - has storing frequency conversion circuit generating auxiliary pulse train with PRF higher than input pulse train
Inventor: OELSCH KURT
IPC: G01P3/489
Filed: 1975-07-28
Abstract: The converter derives a test value after conversion of a pulse train p.r.f. The convertor has a storing frequency conversion circuit generating an auxiliary pulse train whose pulse repetition frequency is higher than that of the input pulse train, but inversely proportional to the spacing of last two pulses in the input train. The auxiliary pulse train frequency is converted into the test value. The pulse train is generated by two scanning sensors (12, 14) responding to marks on a movable part (10). They are staggered w.r.t. each other in the direction of movement of the parts. The storing frequency conversion circuit responds to the time interval between the appearance of pulses in the two sensors (12, 14).

Title: Piston and cylinder feed pump - spring loaded piston ring with axial play controls fluid passages through piston during reciprocation
Inventor: MARIN HEINER
IPC: F16J1/09
Filed: 1975-09-17
Abstract: The piston (1) performs reciproacting movements within cylinder (2). The piston is fitted with ring (7) with an axial play in groove (15) and forced permanently towards the sloping part (9) of the groove by spring (8). Along the circumference of the piston a number of axial passages (10, 11) are provded connecting the cylinder spaces on either side of the piston. The piston ring is of a material which tends to lag behind during the reciprocating movement of the piston in such a manner that when the piston moves in direction (6) the piston ring rests tightly against the inclined surface (9) of the groove, hereby closing the passages and the piston performs the compression stroke. When the piston moves in opposite direction, the ring by staying behind lifts-off from the inclined surface freeing the passages. The piston performs the suction stroke.

Title: Interference suppression circuit - for mechanical counter switch contacts, has store memorising switching states transmitted to processing circuit from decade contact planes
Inventor: BRUECKNER HERBERT
IPC: H04B15/02
Filed: 1975-11-07
Abstract: The circuit suppresses contact interference in mechanical decade counter switches. Contact planes engage each other at decade ends. Their switching states are transmitted to a processing circuit. A store between the counter outputs and the processing circuit maintains the last reliable switching state until a perfectly reliable contact state is established in all counter contact planes. The store is controlled by a control circuit, in turn controlled by the counter switches. When such a reliable contact state exists, it delivers a release pulse to the store, so that the new switching state can be stored, and from there retransmitted to the processing circuit.

Title: Superconducting composite strip for high field coil windings - has strong continuous fibres coated with superconductor in metal matrix
Inventor: POESCHEL EVA DIPL CHEM DR
IPC: H01L39/12
Filed: 1976-05-22
Abstract: Superconducting composite strip has a matrix of a metal (I), which is good electrical conductor, and embedded high-strength continuous fibres (II) with a dia. of 6-15 mu m (II) having an approx. 1-2 um thick coating of a brittle superconducting intermetallic cpd. (III) of the A3B type (in which A is Nb or V and B is Si, Ge, Sn or Al) with beta W/A 15-structure (II) pref. consists of C, graphite or W. The composite is ductile and has high strength (over 70 kp/mm2 e.g. up to 100 kp/mm2 for C in Al). The use of (III) in the form of a thin film has a favourable effect on its transition temp. The high critical magnetic field strength and mechanical strength of the strip make them suitable for winding high field coils. Also, the rectangular section and relatively high critical current density allow a large number of winding in a small space, e.g. a superconductor of 0.7 x 1.5 mm2 section can be wound to a dia. up to ca. 15 cm without impairing its mechanical and superconducting properties. The composite contains 15-50 vol.-% coated (II) and is produced by coating (II) with (III) by chemical vapour deposition and embedding in a (I) melt. E.g. C fibre yarn was coated with V3Si and embedded in Al, Cu or Ag.

Title: Hydraulic one-man mine transporter - has trolleys travelling over hydraulic tube, connected magnetically to plugs forced through tube
Inventor: HERWIG WALDHORST
IPC: E21F13/00
Filed: 1976-08-04
Abstract: The hydraulic transported for personnel in mine galleries, uses one-man trolleys with its rollers running on tracks in the form of fins extending each side of the hydraulic tube (20). The trolley is propelled by a plug (40) which is forced hydraulically through the tube, and is connected to it solely by magnetism. The tube forms a closed loop in which is incorporated a drive unit with a pump (30) supplying the pressure, the tube being non magnetic. The trolley carries a magnetic plate underneath. The drive unit also acts as a station for braking the plugs, and includes a section without pressure (32) followed by a section where the plugs are retained and released by swinging latch arms (2). The pumps i inserted in a by pass line (31) to the conveyor tube. This tube may be of plastics material.

Title: Hose for droplet or under-field watering - has spiral cross-section with spiral ends connected by expansible cross piece in which are outlets
Inventor: KABAI DESZOE
IPC: F16L11/12
Filed: 1976-09-22
Abstract: The hose cross section has approximately a spiral form. The ends of the spirals are connected by an expansible longitudinal cross piece which is closed in the pressure-less state of the hose and runs radially. With increasing internal pressure, it is bent in the direction of a peripheral position. At longitudinal spacings in the cross-piece there are outlet channels with a middle region, whose cross section reduces an increase in the internal pressure. There is a selectably connectable compressd air connection for periodically cleaning the hose system while a wetness meter regulates the intensity of watering.
