Title: Valve for the pressure medium in hydraulic or pneumatic lifting devices
Inventor: BRYNTSE A I
IPC: F16K1/38
Filed: 1973-09-27
Abstract: 1385008 Valves BYGG-OCH TRANSPORTEKONOMI (BT) AB 27 Sept 1973 [3 Oct 1972] 45367/73 Heading F2V In a manually operated valve for use in hydraulic or pneumatic lifting devices a conical valve member 2, which co-operates with a seat 6, moves in a small chamber opening into a larger chamber 4 connected to the pressure medium inlet. A small clearance between the valve member and the wall of the small chamber produces a pressure drop, on opening the valve, which produces a resultant force acting on the valve member, due to fluid pressure, acting in a direction opposing the force applied to open the valve. The valve member is loaded by a helical spring 3. When full flow is required the valve member is moved into the larger chamber 4 a distance greater than "a".

Abstract: 1,199,748. Measuring strain, electrically. SAAB A.B. Oct. 5, 1967 [Oct. 7, 1966], No.45371/67. Heading G1N. In a tensile strength testing apparatus, the tensile force exerted on a specimen 17 Fig.1 is measured by a dynamometer 4 incorporating strain gauges 10. The strain is measured by an extensometer 18 Figs. 1 and 3 comprising bracket parts 21, 22 respectively fixed to two parallel bars 25, and bracket parts 23, 24 which are slidably adjustable on the bars. The bracket parts each have a cutting edge 28, which edges are arranged in pairs urged together by springs (not shown) on the bars 25 to grip the specimen between them as shown. The spacing between the two bars 25 is selectively adjustable whereby the cutting edges can be set in the required datum positions gripping the specimen prior to the application of the loading tension. In operation, the upper and lower brackets, Fig. 1 are guided parallel to one another by telescopic P.T.F.E. sleeves 31 as the specimen is stretched, inner sleeves 32 being attached to the upper brackets and outer sleeves 33 to the lower. The relative displacement between coacting inner and outer sleeves is sensed by movement of a core 40 within a coil 36. The two coils 36 and the strain gauges are connected to an XÀY recorder which produces a force/elongation curve of the test.

Title: Improvements in or relating to the transmission and reception of pulse control signals
IPC: H04Q1/32
Filed: 1968-09-27
Abstract: 1,236,215. Automatic exchange systems. SOC. ITALIANA TELECOMUNICAZIONI SIEMENS S.P.A. 27 Sept., 1968 [27 Sept., 1967], No. 46074/68. Headings H4K and H4R. In a system for transmitting metering pulses over a speech path with the minimum of interference, the metering pulse train is converted into a train of pulses of alternating polarity, i.e. each original pulse is converted into a single transition of polarity which is transmitted over one leg of the loop to a meter circuit which converts each polarity transition into a pulse suitable for operating a meter. It is mentioned that this method of transmission reduces noise on three counts, viz., current required is minimized, one of the edges of each metering pulse is dispensed with (and the other one is in fact rounded to further minimize noise) and electronic components are used at least in the receiver. As shown in Fig. 1, a meter circuit is associated with a repeating coil TS 2  of a first group selector, while a metering pulse generator which produces a pulse train whose rate depends on the connection obtained is connected to another repeating coil TS1 in the speech circuit. As each metering pulse occurs on terminal Tr it flips bi-stable circuit 1, 2 from one state to the other so that a contact s connects the b wire to either a negative - E or a positive + E battery. The edges of the signal thus applied to line are rounded by a capacitor C and the amplitude of the signal is limited by back-to-back Zener diodes Lz. At the receiver, capacitor C1 or capacitor C2 is charged via diodes D1 or D2 respectively, in dependence on the polarity of the received signal. Assuming that initially capacitor C1 is charged negatively, then reversal of contact s causes C2 to charge positively until the p.d. across Zener diode Z causes it to break down, whereupon C1 discharges and allows transistor T to turn on momentarily. Pulse shaper Tm thereupon produces an output metering pulse at its terminal u. When contact s next places negative battery on the line capacitor C1 charges rapidly while C2 discharges through Z, thereby temporarily turning-on T and thus causing shaper Tm to emit another metering pulse. Fig. 2 depicts the pulse pattern at various parts of the system, (a) being the input metering pulse train, (b) the polarity transitions on the line, (c) the pulse output of transistor T and (d) the output metering pulse train. In another embodiment (Fig. 3, not shown), the Zener diode is dispensed with and the two capacitors C1, C2 are effective on individual complementary transistors whose outputs are both connected to the pulse shaper. In yet another embodiment (Fig. 4, not shown) only one capacitor is utilized. Its charging and discharging by polarity transitions is detected by a pair of D.C. coupled transistors and their output, after differentiation in a C.R. circuit, is applied to a pulse shaper.

Title: Apparatus and method for preparing a biological sample
IPC: G01N15/14
Filed: 1966-10-17
Abstract: 1,101,063. Sorting biological cells photoelectrically. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 17, 1966 [Nov. 17, 1965], No. 46235/66. Heading G1A. Biological cells having a particular characteristic are separated from a sample of cells by passing them along a narrow passageway which allows only one cell to pass at a time detecting which cells have the characteristic and diverting the detected cells to a collecting station. Cells from a cervical smear to be tested for cancer are fed along a capillary tube 3 and tested using the system disclosed in Specification 1, 080, 084. Normally a valve 14 is open and a suction pump draws the sample into chamber 12. When a cancerous cell is detected, valve 14 is closed and 15 is opened to draw the cell into the capillary tube 11. The cancerous cells collect on a slide 20 for examination by a cytologist. The detecting system can give signals indicative of different types of blood cells such as leukocytes, red cells and lymphocytes and these signals may operate a plurality of corresponding diverting means. In a modification the capillary tube 3 is made of steel and terminates close to the ends of two steel capillary tubes one of which has a greater suction applied to it than does the other. The sample normally passes in small drops to the higher suction tube, but is deflected, on detection of a cancer cell, to the other tube by reversing the suction, momentarily increasing the suction on the other tube or, electrostatically by applying 600-1000 v to the other tube.

A winding machine of the kind in which a tending device travels relatively to a plurality of winding stations is characterized by the fact that the device delivers a fresh supply package to each winding station as and when required and lays out a yarn end from the fresh supply package such that it can be picked up by the automatic knotting means of the winding station. Fig. 2 is a view of the tending device T that travels along a support tube 23 and rail 21. On reaching a winding station that needs a fresh supply cop K the tending device is automatically stopped and a single revolution motor 43 causes a conveyor belt 40, carrying pockets 41, to shift by one division to cause:- (a) a fresh supply cop K to be removed from the container 42; (b) a previously removed cop to arrive at station A where a suction pipe 47 acts on the cop to suck away the end turns and shears 48 cut off the removed length; (c) a cop previously at station A to move to station B where the cop is displaced axially towards the winding station, the cop is lifted by a small amount from its pocket 41 and is rotated by several revolutions to unwind a thread piece that is sucked up by a nozzle 52, the cop being then returned to its pocket 41; and (d) a cop previously at the station B to drop out of its pocket 41 into a shaft 57 to deliver the cop into the readiness position K2 (Fig. 1, not shown) of the winding station. The thread extending between the nozzle 52 and the cop at position K2 is then cut by shears 58 (Fig. 1), the length above the shears 58 being sucked away by the nozzle 52 and the length below the shears 58 being sucked into a readiness nozzle 16 of the winding station where it can be picked up by a thread transferring lever 15 and fed to a thread seeking element 6 for conveyance to the automatic knotting means of the winding station. Each winding station has a stripper lever 9, Fig. 1, that removes empty cop tubes and deposits them on a removal belt 10. The suction air that is necessary for the pipe 47 and nozzle 52 is taken from the pipe 26. The tender T carries a connection pipe 29 that is aligned with bores in the pipe 26, those bores that are not in communication with the pipe 29 being closed by valves 28 pivoted at 30.
