Title: Air cooled electro-magnetic for tracked hovercraft - with cooling spaces in coil formers and forced convection
Inventor: HOFFER OTTO DIPL ING
IPC: H01F7/06
Filed: 1974-09-04
Abstract: The electro-magnets which support the tracked hovercraft have their windings on special formers with rectangular ducts in them to form large area cooling surfaces for the airstream. The cooling surface can be increased by dividing the coils into separate sections, each separated by an air duct. The cooling airstream comes partly from forced convection, due to the movement of the vehicle, and partly through a back-up blower. To increase the cooling effect still further special spherical, conical or similar surfaces are sited in the ducts to set up a turbulent airflow.

Title: 80 mhz carrier frequency system - quinary grouping for 14,400 communication channels with phase locked loop carrier signal generation
Inventor: MAERKL GEORG DIPL ING
IPC: H04J1/06
Filed: 1975-08-16
Abstract: An 80 MHz carrier frequency system based upon quinary group construction provides 14,400 communication channels. The carrier frequency is generated from a base of 1.1 MHz. The carrier frequency generator operates to the relationship. ft=nx1.1 MHz plus-or-minus 0.22 MHz. The base frequency of 1.1 MHz is derived by division (T1) of a stable control frequency (fst=2.2 MHz). The generator frequency (ft) is modulated with a 0.22 MHz signal from a divider (T2) and a third divider (T3) generates the 1.1 MHz signal. This signal is processed through a phase discriminator (PD). The phase locked loop so formed ensures an accurate, stable frequency output.

Title: Flow velocity measuring device - sends ultrasonic waves through flowing medium to two transducers and measures phase shift
Inventor: MAGORI VALENTIN DIPL PHYS
IPC: G01F1/66
Filed: 1975-09-18
Abstract: Two transducers operate as receivers, while the transmitted ultrasonic waves are generated by a third, operating as the sender. Ultrasonic beams' phases are shifted by the flowing medium, and this phase shift is a measure of the flow velocity. An evaluating electronic circuit connected to the receiving transducers converts the phase difference into a measurement signal. At least the receiving transducers have piezoelectric, ceramic oscillating elements with a quarter lambda layer on their sound radiating surfaces. Their acoustic characteristic impedance for the signal frequency lies between those of the flowing medium and of the oscillating element.

Title: Braking for axial motion of jack piston shaft - involves use of eccentric disc surrounding shaft activated by piston shafts (SW081176)
Inventor: GATERMANN BODO
IPC: G05G5/22
Filed: 1975-11-26
Abstract: Movement of the piston shaft in a jack is slowed down or stopped by a brake. This is performed by an eccentric which slides around the moving shaft. A large area of contact reduces pressure required and reduces risk of damage. A piston jack shaft (1) moves in an eccentric opening (12) in the eccentric brake (8). The brake is turned in one direction or the other by the action of pneumatic or hydraulic jacks (17, 18) whose piston (15, 16) shafts (19, 20) act on operating surfaces (13, 14) on the eccentric brake. Compressed air or fluid under pressure flowing into the orifice (22) of the jack (17) causes braking pressure to be applied to the brake. Rotation in the opposite direction is obtained by operation of the other jack (18).

Inventor: LOPATA KARL PETER
IPC: B41F16/02
Filed: 1976-08-23
Abstract: The equipment to print textile fabrics, by transfer of dyestuff from a carrier film, uses heat and vacuum while the fabric and film are in contact with each other. The vacuum cap is placed round the hollow supporting cylinder carrying the materials, with an opening for the fabric and the dye carrier film or carrier band to pass in and out, the cap being a tube closed at both ends. The design gives a simple equipment which applies a constant vacuum pressure on the fabric and the dye carrier film, with easy operation.
Patent DE-2638844-A1 (DE)
Title: Discontinuous flow measurement of radioactive specimens - with device feeding samples and liquid successively to detector
IPC: G01T7/02
Filed: 1976-08-28
Abstract: A method fo discontinuously measuring the flow of radio-activity in a scintillation counter consists of taking a series of samples in succession from specimen containers by means of a hose connected to a suction pump. These samples are each successively fed into a collecting funnel with a valve at its outlet. These valve is used for metering the sample, together with a washing liquid, into a measuring vessel contained in a conventional detector. The measurement is carried out in this detector, the mixture sample then removed from the measuring vessel by pumping it out, then this measuring vessel is flushed out with a complete change of the washing liquid and a new cycle is commenced with the next specimen. Preferably, the sampling vessels are covered with a liquid possessing a high boiling point, low density and low vapour pressure, which does not mix with the specimen, and is not reactive and not toxic. In particular, this liquid may be aqualane. Used for chemical, biochemical and clinical-chemical analysis, e.g. of liquid phase from radioimmunological tests, blood samples in nuclear medicinal diagnostics and so on. The risk of confusing samples is considerably reduced. The automatic operation is considerably improved and the resultant elimination of manual operations greatly reduces the risk of contamination of the operator. The measuring vessel entirely occupies the cavity designed for it in the detector, so that readings are not falsified by differences in position of the specimen. The amt. of carry-over from one specimen to the next is extremely small, thus eliminating risk of falsification form this cause.
