Title: Air cooled IC engine axial blower - has two guide blade wheels, with interposed blade arrangement
Inventor: SCHLEIERMACHER HERBERT
IPC: F04D29/54
Filed: 1974-06-12
Abstract: Axial blower, particularly for air cooled internal combustion engines, with a guide blade wheel, which is of one piece casting construction with a hub and a tubular blower housing. The guide blades are so formed and fitted on the circumference of the hub that the cores of the casting shape can be drawn parallel, or nearly so, to the blower axis and a second guide blade wheel is introduced in the flow direction behind the first guide blade wheel in the axial blower. The hub parts of the two guide blade wheels extend to approximately half the guide blade lengths, and the guide blade lengths projecting outwards over the hubs project inwards into a space between two adjacent guide blades of the other guide blade wheel.

Title: Pulse doppler radar distance ambiguity solving arrangement - uses reciprocal of sensing frequency for setting value of control cct
Inventor: POUPLIER LOTHAR DR ING
IPC: G01S13/22
Filed: 1974-08-31
Abstract: The arrangement for solving the distance ambiguity of a pulse-reproducing radar instrument utilises the sensing period (reciprocal of the sensing frequency) for the setting value of a control circuit. The control deviation is divided by the ambiguity number and is multiplied by a relationship giving the actual sensing period divided by the basic sensing period, and after division by the ambiguity number is utilised for controlling the sensing period. The radar receiver comprises a distance gate followed by a distance discriminator and a controller for the sensing period, so that the target echo pulse remains always in the distance gate.

Title: Friction-driven disc crusher - operates above critical speed and has scraper to control thickness of layer of processed material
Inventor: MORTENSON MAGNE PROF
IPC: B02C7/06
Filed: 1975-03-07
Abstract: The disc crusher consists of drum (1) with feed opening (5) on one face and outlet (6) on the other face. The drum is kept rotating by drive pulley (3) engaging the outside surface via friction bandages (2). The crushing discs (7) stand freely vertically within the drum and will never completely follow the peripheral speed of the drum. The relative movements between the drum and the discs result in grinding action. The processed material, however tends to stick to the inside of the drum, after being ejected from between the discs. Scraper arrangement (10) controls the thickness of the layer of ground material.

Title: Ramp voltage generator with very slow rise time - charges capacitor with pulses at intervals longer than pulse duration
Inventor: GROSSE-BRAUCKMANN WOLFGANG
IPC: H03K4/50
Filed: 1975-03-12
Abstract: The ramp voltage generator, for producing very slowly rising ramp voltages of the order of hours, has pulses charging or discharging a capacitor at intervals and arranged so that an interval between pulses is a multiple of the duration of one pulse. The charging pulse trains is defined by a square wave generator whose output pulses are differentiated by an RC circuit to give decaying spike signals.

Title: Purifying viscose spinning machine waste gases - large volume spinning bath degasified in closed circuit excluding air
Inventor: LUETHI FRIEDRICH
IPC: C01B31/26
Filed: 1975-04-04
Abstract: The waste gases of viscose spinning machines are purified with the recovery of H2S and CS2 by providing a spinning bath of a volume fully adequate to absorb the gases set free during the coagulation and regeneration processes. This is drawn off into a closed circuit, air being excluded and degasified away from the spinning trough. The ratio-tons of fibre to metres of spinning bath, is maintained at 1:500. The spinning trough is designed so that a bottom area of 450cm2 is allocated for the spinning of 54'000 den, and the spun strand dwells for at least 1,5 secs. in the bath. Practically all the H2S and CS2 released in the spinning bath can be absorbed.

Title: Thread rolling machine - with thread rolls on two armed levers spread apart by wedge thrust at upper end
Inventor: ABELE JUERGEN
IPC: B21H3/04
Filed: 1975-05-30
Abstract: A machine for the rolling of threads and for similar profiling operations is equipped with two form rolls, each supported in one end of a two-armed lever and individually driven in synchronism with each other through a fan-out gear box. The other ends of the lever are chamfered and fitted with roller so that they can be spread open when a wedge is pressed between them. This moves the thread rolls uniformly against the workpiece. This machine can produce profiled workpieces in a wide dia. range and with greatly varying processing depths. There is adequate space under the rolls to accommodate an automatic loading device. The rolls are horizontally adjustable with roll carriers so that the workpieces are always loaded at the same centre and loading/unloading devices need not be readjusted.

Title: Sphygmometer measuring precisely without intra-arterial application - arterial pulse pressure is transformed to electronic signal, analysed and recorded (SW240177)
Inventor: LINK WILLIAM T
IPC: A61B5/022
Filed: 1975-07-18
Abstract: Sphygmometer has means to apply a selectively variable pressure in the neighbourhood of a blood vessel. A device measures a fluctuating magnitude which is proportional to the sum of a time-dependent fluctuating component reproducing the pulsating pressure inside the bloodvessel and the selectively variable pressure applied externally to the blood vessel. The fluctuating magnitude is transformed into an electronic signal reproducing a time derivative for at least the fluctuating component of this magnitude. Another device analyses variations in the electronic signal derivative caused by changes in the applied pressure whilst a third device produces an output signal from the analyser indicating the physical condition of the subject under investigation.

Title: Plastics pressure reducing valve - is fitted with resilient fluid cells obviating close tolerance requirements to suit mass production needs
Inventor: AUS DER AU RUDOLF DIPL ING
IPC: G05D16/06
Filed: 1975-07-28
Abstract: The pressure reducing function is performed by a combination of two fluid cells (3, 9), one of which (3) is in the form of a squeeze valve opened and closed by a rod (4), whilst the other (9) is driven against an adjustable force by the pressure of the flow medium and closes the squeeze valve as the pressure rises. The reducing valve may have an integral flow regulator and may itself be integrated in a different unit or used as a separate component. The flexible fluid cells make it possible to produce the valve on plastics injection moulding machines, as no close tolerances are needed.

Title: Ball track worm gearing - has small pitch trapping end balls against each other preventing spreading
Inventor: ARNOLD FRANZ
IPC: F16H25/22
Filed: 1975-10-28
Abstract: The lead screw worm gearing consists of a worm with circular section grooves and a matching nut (wormwheel) with balls running in the tracks between them. The groove pitch is smaller than the ball diameter for a single-threaded worm. Hence all the balls project into adjacent grooves, and the first and last balls (5a, 5b) in adjacent grooves touch each other. Each set of balls is therefore kept aligned and encompass one full pitch, and the end balls, prevent spreading out of the set. The worm gearing therefore has only one circle of balls, as any more will obstruct each other. Doubly-threaded worms have two sets of balls.
