Title: Magnetic separator for components of different permeability - has ferromagnetic inserts to further increase magnetic field produced by super conducting magnetic coils
Inventor: RIES GUENTER DIPL PHYS DR
IPC: B03C1/0355
Filed: 1974-12-28
Abstract: The device is for magnetic separation of components of different permeability having super-conducting magnetic coils to produce a high intensity magnetic field with built in devices to produce higher magnetic field gradients. A separator device allows separate removal of the separated fractions. Ferromagnetic inserts (5) are placed at a separation from each other running through the area of high magnetic intensity (3) through which the material to be separated (4) passes. The inserts (5) are in the direction of flow of the input material. The super conducting magnetic coils (1, 2) for production of the magnetic field are situated parallel to the ferromagnetic inserts (5) and produce a magnetic field (3) at right angles to the inserts (5).

Title: Veterinary blood letting syringe - removing two samples simultaneously without exchanging tubes or other manipulators
Inventor: FELDHAUS EBERHARD
IPC: A61B5/155
Filed: 1975-01-14
Abstract: The blood letting syringe comprises a cannula (1), a holder (2, 3) and a glass test tube (4) for the sample, the holder consists of a tube (2) with the cannulat attached to one end whilst the other open end is sealed by a stopper. A second tube (3) branches off at a sharp angle from the first tube into which the test tube (4) can be inserted, whereby the stopper is formed by another removable glass test tube (4). The syringe is particularly of use for veterinary surgeons removing two samples simultaneously for leucosis and brucellosis testing without disturbing the animal by exchanging tubes and reducing contamination risk to sample.

Title: Filter for injection or transfusion appts. - in which air is evacuated before filter is wetted
Inventor: MAENZ HERBERT
IPC: B01D29/00
Filed: 1975-03-08
Abstract: Filter, for insertion in the liq. circuit of an injection or transfusion appts. in mounted in the cavity of a box which is supplied with an inlet and an outlet for the liq. The filter matl. has is surface at a certain distance from the internal surface of the upper part of the box, leaving a gap. A boring in the centre of the box leads to the cone fitting for the liq. with a connection for a flexible tube. The box includes a part with a spiral groove. A boring at its centre leads to the outlet with an external cone for receiving a protecting stopper or a connector for a flexible tube. The upper edges of the spiral grooves are immediately adjacent to the filtering material. When the liq. passes through the filter in a 1st direction the air present in the boring and in the gap is pushed through the filter before the latter is wetted. It escapes by the press. of the liq. behind it through the outlet in a 2nd direction. The filtering appts. is very simple and construction is not expensive. Air is completely evacuated as the instrument is brought into service; the danger of the intermittent entry to bubbles in the outlet tube is thus avoided.

Title: Contactless optoelectronic machine tool monitoring - provides instantaneous indication of positional changes using LEDs and phototransistors
IPC: G01V8/20
Filed: 1975-08-28
Abstract: A light unit (1) contains several light-emitting diodes (2, 3, 4) supplied from a low current source via a terminal (5).

Title: Control voltage selector using reed relays - has hold on circuit in parallel with input power supply
Inventor: JENSCH HILDEGARD
IPC: H02M1/00
Filed: 1975-10-09
Abstract: The control voltage units are intended for building up into circuits where selection of one of several voltage levels is desired, without using a traversing potentiometer which gives a changing voltage until the set point is reached. It also permits ready identification of the selected circuit by a display. The control voltage is taken from a tapping point (6) between two resistors (51, 5). One (51) in series with a relay contact (31). The relay coil (21) is connected to the supply y a push button (T1) on one side and a limiting resistor (3) on the other. A further limiting resistor (4) joins the coil to one side of the relay contact (31) and holds the relay once the push button is released. Several such circuits (52, 22, 32, T2) in parallel give selected control voltages. By selection of circuit values the incoming coil current, when the pushbutton is depressed, can give a volt drop sufficient to cause the already closed relay to drop off thus avoiding an error in the output during transition.

Title: Water bar screen rake - guided on rails with lower section swivelled by screw or worm drive for rake engagement
Inventor: SCHROEDER GUENTER
IPC: E02B8/02
Filed: 1975-10-15
Abstract: The bar screen facing an underground water channel is cleaned by a rake which is guided on vertical rails. The rails can be moved by a leadscrew or a worm drive in the operating position of the rake and back. The rails are divided into an upper rigid and a lower swivelling section. The leadscrew or worm drive act solely on the latter. This results in the smaller overall space requirements independent of the channel depth. The rake mechanism is simple and operates noiselessly.

Inventor: FOURCIN ADRIAN JOHN
IPC: G10L21/06
Filed: 1976-01-22
Abstract: 1533112 Speech pattern derivation LARYNGOGRAPH Ltd 8 Jan 1976 [24 Jan 1975]  3269/75 Heading G1N(E) [Also in Division G5] In a laryngograph for monitoring the vocal fold vibrations in a speaker's larynx in speech training &c., a single frequency oscillator, Fig. 2, or a broad band oscillator, Fig. 3, supplies a carrier wave to a transmitting aerial positioned adjacent the larynx. The modulated carrier wave is picked up by a filter further adjacent aerial whose output is detected 3, Fig. 2, or demodulated 8, Fig. 3. The result is filtered 6 to produce a vocal fold waveform Lx representative of the "voiced" sounds in each utterance. The carrier wave level is maintained constant by two alternative types of feedback system controlling the oscillator 2 or the detection circuits (which may employ slicing techniques). The electrode aerials may take the form of a standard printed circuit board which is etched to produce a circular element with a concentric ring spaced therefrom. Larynx waveform L X  displays and vocal fold vibration determination. The signal from the filter amplifier 6 is fed via a band pass filter 40, Fig. 4, which supplies an amplitude sensing circuit 51  connected to a memory input control 52. The control 52 controls the input pulses, from a clock 50, which are gated 48 under the control of a closure pulse generator 42, supplied, as shown, by an infinite clipping circuit, to provide a uniform pulse for each larynx closure. This enables pulses to be counted 49 to give a measure of the vocal fold vibration period Tx which is eventually stored in a main memory 54. The pulses from the counter 49 are directed by the control 52 into a random access memory 54 connected to a display unit 57. The signals reaching the display must be logarithmically converted at 56, or at any other convenient point in the system. Alternatively, suitable non- linear clock pulses may be used. A chart recorder 45 or a "X-Y" plotter may feed the memory via a buffer memory so that only voiced segments of the speech are drawn slowly, while intervening voiceless pauses are moved over quickly. In a further embodiment, Figs. 6 and 7 (not shown), the characteristic frequency in two frequency bands F 1 , F n  are shown on a stored display with a colour distinction between parts of an utterance which are voiced, fricative (consonants) or voiced fricative in form.

The retainer is releasably connected to a second tension member on the handbrake lever in the direction of braking. This second tension member engages a second handbrake lever at the driver's position.
