Title: Improvements in or relating to luminescence diodes
IPC: H01L23/36
Filed: 1969-09-29
Abstract: 1,242,660. Electroluminescence. SIEMENS A.G. 29 Sept., 1969 [30 Sept., 1968]. No. 47761/69. Heading C4S. [Also in Division Hi] A luminescent PN diode 1 is supported on a tantalum oxide layer 2 on a tantalum body 3.

Title: Colour separation of discrimination in pattern recognition systems
IPC: G06T1/00
Filed: 1973-10-16
Abstract: 1426311 Colour pattern recognition GEOMETRIC DATA CORP 16 Oct 1973 [16 Oct 1972] 48139/73 Heading G4R [Also in Division G1] The invention relates to a colour-discriminating, pattern-recognition system, particularly for white cells in a blood smear, by detecting the blue/green content of the cytoplasm after treating with Wrights stain. The Specification explains with reference to Fig. 2 (not shown) how the difference in size and colour absorption of, e.g. platelets, eosinophil, and neutrophil cells enables an improved differential count to be made. Scanning system (Fig 1).-The slide 25 is placed on a platform 24 and a small section is illuminated by a flying-spot-scanner comprising a cathode-ray tube 20 providing e.g. a 3 inch square raster which is reduced at the slide to a 300 micron scan by a microscope lens system 22. After each cycle the platform is moved by a servo-system 34 to scan an adjacent section. Colour discriminator (Fig. 3).-The light beam 38 transmitted through the slide is separated into its colour components by dichroic mirrors 102, 104, which reflect out the green and blue components (via plane mirrors 110, 108) on to photomultipliers 120, 116. The remainder of the beam (red) passes to photomultiplier 118. Further discrimination is provided in the subsequent signal processing circuit Fig. 4 (not shown), where the blue signal is subtracted from the green signal to eliminate any possible red signal component to more easily distinguish a white cell; also the green is subtracted from the red to distinguish the orange colour component of an eosinophil cell. These signals are then fed to shift registers connected to a pattern discriminator, which is, e.g. of the kind described in Specification 1,363,211 (Division G4) and which is actuated in response to a white-cell-signal on the blue green line, Fig. 5 (not shown).

Title: Automatic diluting apparatus
Inventor: COULTER WALLACE HENRY
IPC: G01N1/38
Filed: 1963-12-05
Abstract: 1,026,310. Delivering measured quantities of liquids; sampling liquids. COULTER ELECTRONICS Inc. Dec. 5, 1963, No. 48155/63. Heading B8N. [Also in Divisions B1 and F1] An automatic diluting apparatus comprises a conduit system having operably connected thereto two vessels the volume of each being controllably variable and both of which are filled with a fluid diluent, a predetermined quantity of a fluid concentrate being introduced into the conduit system by increasing the volume of one of the vessels by a predetermined amount, whence a known volume of fluid diluent is discharged by controlled alteration of the volume of the other vessel, said discharge fluid also carrying with it the said quantity of fluid concentrate. In a specific embodiment of the apparatus, Fig. 1, diluent under pressure is fed through tube 55 to valve 66 and hence into cylinder 30 via tube 45, to move the piston 38 between stops 40 and 44 and thus displace a predetermined volume of diluent through tube 47; this volume may be varied by adjusting the size of the piston or the stops. The apparatus is filled with diluent and the sampling nozzle 58 placed in a vessel 65 containing concentrate, a predetermined quantity of which is drawn up into tube 58 by controllably withdrawing the plunger 122 located in vessel 72 which is joined to tube 60. When the concentrate has been taken up, the vessel 65 is replaced by a clean vessel and the nozzle 58 wiped free of sample. The valve 66 is then rotated through 90 degrees and due to pressure from 55 on piston 38, the diluent in cylinder 30 is displaced through tubes 45 and 60, thus displacing the concentrate into the clean vessel and also diluting it to a known degree.

Abstract: 1406547 Making DC machine coils ESSEX INTERNATIONAL Inc 16 Oct 1973 [12 Feb 1973] 48208/73 Heading B3A A machine for placing wire in slots of a stator of a D.C. machine or of a coil transfer apparatus for subsequent transfer to a stator includes a wire guide 32 through which the wire 42 is pushed and guided into the slots during relative movement of the guide and slots. In one embodiment for stator winding the guide is composed of a flexible tube 98, Fig. 4, which is reciprocated in the direction 48 by an eccentric pin 120 engaged in a slot 118 on a block 110 fixed to a rod 108 supporting the tube end. The stator is indexed by a mechanism (140), Fig. 3 (not shown), in timed relation with the tube end movement. The indexing may be in one direction to produce wave-like wire turns or in alternate directions to produce coils. The wire feed is effected by a driven roller 302, Fig. 4, engaged by idler rollers 304, 306 around which a belt 342 passes. The roller 302 has a wire receiving groove closed by the belt. In an alternative embodiment, Figs. 8-10 (not shown), the tube end (98) is moved in a figure of eight path (392) and the stator is rotated continuously in one direction or in alternate directions by gearing (402), (404), Fig. 10 (not shown). In a further embodiment, Fig. 11, the tube end 98 is moved in reciprocation in a direction 48 by an eccentric pin 120<SP>11</SP> drive and also rotated by a barrel cam drive 430 through a rack and pinion 424, 426. A similar drive may be used to direct the pushed wire between the fingers (64), Fig. 12 (not shown), of a coil transfer apparatus. In a still further embodiment, Figs. 13 and 14 (not shown), the tube end is provided in a bush (474) pivoted between adjacent links (476), (478) of a chain (454) guided in a serpentine path by sprockets. In a final embodiment the tube end 98, Fig. 15 (not shown), is mounted on a rotary plate (480) on a reciprocating slide (300). In all the embodiments the wire is pushed through the guide or tube and is not subjected to tension when wound. Hence a reduced thickness of insulation or enamel is required on the wire than when the wire is tensioned on the stator or transfer apparatus arms.
