Title: Apparatus for studying the physical properties of particles
IPC: G01N15/12
Filed: 1962-03-27
Abstract: 927,346. Pulse discriminating circuits. W. H. COULTER. March 27, 1962 [April 6, 1961], No. 11723/62. Chess. 40 (6). [Also in Groups XIX and XXXVI] Apparatus for counting the number of particles of greater than predetermined size in a unit volume of liquid comprises means for passing the liquid through an aperture and a two-state control circuit which enables or disables the passage of electric current through said aperture, said electric current being responsive to the passage of said particles to generate signals. In the manner described in Specifications 722,418, 865,069, 865,070 the test liquid in container 70 is subjected to a vacuum so as to unbalance a manometer 60. Operation of reset button S2, Fig. 3b, restores the counters and sets control flip-flop 106 to its first state. When the vacuum is released the liquid flows between electrodes 66, 74 between which flows a direct current. The resistivity of the liquid is affected by the presence of a particle such as a blood cell, food and fat particles, dusts and so on and the passage of a particle produces a signal which is amplified and displayed on a cathoderay tube. When the mercury in the manometer reaches start terminal 90 an amplifier and gate in the form of a limiter valve V16, Fig. 3b, is opened to transmit all pulses of sufficient amplitude to pass a threshold circuit to counters V19, V22 which effect division by 100 before feeding an electromagnetic counter 192. When the mercury reaches the stop terminal 92 flipflop 106 is reversed to cut off the flow of current between the electrodes 66, 74 so preventing damage to the test liquid by boiling. Threshold circuit. As described, the apparatus can be set to count particles with volumes greater respectively than 35 or 50 cubic microns, Fig. 2, sample traces being shown to the left and right of the cathode-ray tube screen 212. The desired sizes are set up on potentiometers R55, R56 and one or other is selected by a switch S3 to apply an appropriate back-bias at terminal 146 to rectifiers V12, V13. The signals from electrodes 66, 74 are amplified and only if they are of sufficient potential to render V14A conducting and V14B non-conducting do they pass to V16 and the counter.

Title: Improvements relating to electric motors
IPC: G06M1/10
Filed: 1956-04-19
Abstract: 825,756. Electric selective signalling systems. DIRKS, G. July 18, 1957 [April 19, 1956], No. 11890/56. Class 40 (1). [Also in Group XXXV] Apparatus for producing rotation of a shaft under the control of electrical pulses includes a counting device generating output signals in response to the attainment of predetermined values and an electric motor with a poled rotor mounted on the shaft having a stator with a number of poles different from the number of poles of the rotor. As described, pulses on a line 7, Fig. 2, pass through a gate 8/1 to cause stepping of the discharge in an electronic counting tube 9/1, a switch 14/1 being so positioned that after a predetermined number of pulses, six for the circuit shown, a signal is passed to cause a triode 15/1 to conduct, thereby energizing the stator coil 3/1 of an electric stepping motor, Fig. 1, whose rotor 5 moves until the uppermost rotor pole is adjacent the stator pole 2/1. The voltage increase at the grid of the triode 15/1 is differentiated at 19/1 and the differentiated output is fed to close the gate 8/1 and open a gate 8/2 so that the input pulses on the line 7 are now fed to a second counting tube 9/2. This tube has associated circuits analogous to those of the tube 9/1 with an additional connection over the lead 23/1 to the zero of the counting tube 9/1 so that the tube 9/1 is zeroized and the coil 3/1 de-energized when the predetermined count for the tube 9/2 has been attained. Thus each time one of triodes 15/1 to 15/4 is made conducting, the preceding triode is made non-conducting and the rotor 5 is rotated a further step. A modified arrangement (Fig. 3, not shown) employs a motor with ten stator coils having a rotor with nine poles. Other forms of counter such as a ring counter or a chain of binary trigger stages may be employed.

Abstract: 585,875. Centrifugal moulding of powdered metal. GENERAL MOTORS CORPORATION. June 28, 1944, No. 12266. Convention date, July 10, 1943. Addition to 554,110, [Group XXII]. [Class 87 (ii)] [Also in Groups II and XXII] A method of forming porous metal articles comprises distributing into a cylindrical shape a mixture of metal powder, a binder and a volatile solvent, driving off the solvent while rotating the charge so distributed and then sintering the shaped article. The centrifuge comprises a cylindrical body 20 rotated by a shaft 22 and having a bore with a part 26 of greater diameter than the inner portion 27. A cover 28 has a central aperture 30 of the same diameter as the portion 27. Into the bore part 26 is inserted a backing shell 32 of metal, a refractory non-metallic material such as graphite or in some cases a material such as asbestos paper. A mixture of metal powder, binder and a highly volatile solvent in the form of a thick slurry is poured on to the rotating shell from a hopper 33 and levelled with a blade 38. The solvent is evaporated by warm air after which the shell and powder mass can be removed and sintered to form a coherent body. The binder is preferably a substance that will decompose on heating, such as pyroxylin dissolved in an organic solvent. If the metal powder comprises a mixture of 90 per cent. copper and 10 per cent. tin, a temperature between 1550 and 1750‹F. should be used for sintering, whilst for a mixture of 90-95 per cent. iron and 10-5 per cent. copper a temperature of 2050‹F. would be suitable. A temperature of 2000‹F. should be used for copper nickel alloys in which nickel is present to approximately 60 per cent. A reducing atmosphere is employed and the sintering should be carried out for 15-30 mintues. If making a composite bearing a shell 32 of metal is inserted into the centrifuge and the powder bonded to it during sintering. For other articles the slurry may be poured on to a removable shell. If the shell comprises asbestos paper, this would be destroyed during the sintering process leaving only the porous sleeve.
