Title: Pattern recognition apparatus.
IPC: G06V30/10
Filed: 1967-04-24
Abstract: 1,179,916. Pattern recognition. INTERNATIONAL BUSINESS MACHINES CORP. 24 April, 1967 [9 May, 1966], No. 18704/67. Heading G4R. In pattern recognition apparatus, pattern data is passed progressively through a storage device, the boundary between adjacent patterns is determined, and portions of a pattern overlying an adjacent pattern are removed from a predetermined plurality of storage positions when all the data representative of a pattern is in the storage device and data elements are present in a predetermined plurality of storage positions, the pattern data being passed to recognition means without the removed portions. A flying spot scanner reads a line of characters starting at the right hand end, each character being read in a series of vertical scans (columns), the read data being passed through a 5-scan look-ahead shift register LA1-LA5 and then into a 15-scan main shift register 17 which feeds character recognition circuitry which may be as in Specification 1,102,359 which is referred to. A segmentation circuit 19 which may be as in Specification 1,144,319 which is referred to, responds to the shift registers to produce a segmentation signal indicating that the boundary between two adjacent characters as in register column LA3. AND gates 22, 23 are fed from stages of the look-ahead register and main register to detect conflict of adjacent characters. The conflict may be overhanging, underhanging, abutting or overlap. The bottom 6 bit stages of register columns LA3, LA4 are cleared if AND 22 produces an output (while AND 23 does not) during the first scan after the segmentation, signal, and also if AND 23 produces an output during the third scan after the segmentation signal, via OR 27. Thus conflicting bits are destroyed. Normally data shifted from the look-ahead register passes via AND 33 into the first column of the main register but during the fourth scan after the segmentation signal it is passed instead via AND 31 to auxiliary register 21, a blank "scan" being entered into the first column of the main register. The segmentation signal, 4 scans delayed, causes the recognition circuitry to recognise the character now in the main register which is cleared at the end of the fourth scan following the segmentation signal. During the next scan, the contents of the auxiliary register 21 are passed via AND 35 into the second column of the main register while the output from register column LA5 recommences to pass via AND 33 into the first column of the main register. Fig. 5 (not shown) shows a modification in which conflicting bits destroyed in the lookahead register are first transferred to corresponding bit positions of the first two columns of a 3-scan auxiliary register which replaces that of Fig. 2. During the scan after clearing of the main register referred to, the contents of the 3 auxiliary register columns are passed to columns 2, 3, 4 of the main register and the output from register column LA5 recommences to pass into the first column of the main register.

Abstract: 1,090,990. False-twist crimping. KLINGER MANUFACTURING CO. Ltd. May 6, 1964 [May 10, 1963], No. 18712/63. Heading D1F. A method of producing crimped yarn comprises subjecting the yarn on the run to two successive false twisting operations in opposite directions, the degree of twist imparted by the second false twisting operation being not less than that imparted by the first false twisting operation, and at any one moment a longer length of yarn being subjected to the heating prior to the first false twisting operation than subjected to the further heating. In the embodiment illustrated a polyamide or polyester yarn passes around a driven roller or a magnetically restrained pulley 12, along a groove in heater plate 14, the temperature of which increases along the length thereof, to false-twister head 16 which comprises either a false-twist spindle or a group of rotatable wheels, and then via feed rolls 18, 19, along a second groove in plate 14 to an adjustable guide 24, second falsetwister head 26, feed rolls 19, 28, and package 30. In modifications plate 14 need not be grooved or it may be replaced by two separate heaters.

Title: Improvements in and relating to hydraulic apparatus for lifting and lowering loads
IPC: B66F3/42
Filed: 1920-07-05
Abstract: 168,477. Hydraulic Gears, Ltd., and Wight, J. T. July 5, 1920. Hydraulic transmission of power; machines and apparatus.-In lifting and lowering apparatus operated by a variable stroke pump the hand wheel which varies the stroke of the pump is adapted, after bringing the stroke-controlling member to the neutral position, to operate valve mechanism to lower the load without reversing the pump. The load is sustained by means of a non- return valve whenever the pump stroke is zero. The hand wheel a is fixed to a nut b and rotation thereof causes axial movement of a screwed spindle c. This spindle acts on a stroke controlling member 1 by means of a collar d, a bridge piece f and pins 4, the member 1 being returned to the neutral or zero stroke position by springs k. The pump q delivers through a pipe p past a non-return valve t to a pipe u and the lifting apparatus. Thus when the pump stops delivery the valve t prevents return of the fluid to the pump,. but a safety valve n is always in communication with the lifting apparatus. After the member 1 has been brought to the neutral position further movement of the spindle c brings lock nuts e against a lever h and so lifts the safety valve, allowing the fluid to escape to the supply tank 10, and the load to be lowered at a rate depending on the amount of opening of the safety valve.

Abstract: 1,038,987. Knitting-machines; fabrics. B. PFROMMER. May 14, 1963 [May 16, 1962], No.19011/63. Headings D1C and D1K. A double faced fabric is formed in separate pieces on a circular knitting-machine, the pieces being interconnected by means of a separating thread 1. The machine used is a cylinder and dial machine having cylinder needles and dial needles R which for purposes of illustration are shown in the same plane, Figs. 2 and 3 not shown. To insert the separating yarn 1 as shown in Fig. 1 to knit with loops 8 of the fabric, yarn is fed to the needles Z and behind the latches of the needles R so that as alternate wales of the fabric are knitted on to the dial and cylinder needles then the wales B containing the knitted loops of yarn 1 will be left supported on the needles Z and the needles R will be free from fabric. To remove knitting after the insertion of the separating yarn 1 a yarn 2 is fed to the latches of needles Z and behind the latches of needles R and a yarn 4 is fed to the needles R through the latches of the needles Z. The Z needles then pull the loops of the yarn 2 through the loops of the separating yarn 1 and the needles R pull the loops of yarn 4 through the newly produced loops of the yarn 2.

Filed: 1922-07-11
Abstract: 199,958. Rodriguez, A. O. July 11, 1922. Metals, powdered, obtaining coherent masses from; alloys. - Intimate mixtures of metals, approximately in properties to alloys, are made by reducing the metals to a finely-divided state in which the particles of the softer metals are of larger size than the particles of the harder metal, mixing the whole, and submitting the mixture to kneading, pressure or like mechanical operation, whereby the particles of the harder metal are caused to penetrate or be distributed in the larger particles of the softer metal; the remaining particles of harder metal are then screened from the composite metal formed, and the latter is worked into bodies of the desired form. For example, a composite mass of lead and tungsten may be obtained by triturating a mixture of lead filings and fine tungsten powder, and pressing the mixture through an aperture in the form of a thread, which is broken up, screened, and moulded.

Abstract: 882,298. Starting prime movers. HOLLEY CARBURETOR CO. June 16, 1958, No. 19153/58. Class 38 (4). [Also in Group XXVII] In a shuttle type fuel metering and distributing device 20 for an internal-combustion engine, wherein the amount of fuel injected is varied by adjustment of an abutment 28 means operated during starting of the engine provide increased fuel for starting. The abutment 28 is controlled by a cam surface 42 on a carriage 34 slidable longitudinally along a rail 39 by a suction actuated piston 46. The rail 39 is movable laterally by a linkage 54 controlled by a cam 64 which is rotated by a temperature responsive device 68. The cam is slidable along its actuating spindle 74, Fig. 2, and during normal running is held raised by pressure in a space 82 so that the linkage 54 is controlled by a surface 64a on the cam. On operation of the engine starter switch 95, the circuit of a solenoid 90 is completed to move valve 86 off its seat, releasing the pressure in space 82 so that the cam 64 is moved down and a second control surface 64b thereon co-operates with the linkage 54 to set the rail 48 to produce an increased fuel supply for starting. In a modification, the cam 64 is controlled directly by a solenoid in the starting motor circuit.

Abstract: 999,751. Converting. CENTRAL ELECTRICITY GENERATING BOARD. Aug. 1, 1961 [May 31, 1960], No. 19186/60. Heading H2F. [Also in Division H3] In a pulse circuit for triggering valves in rectifier and inverter circuits and incorporating a pulse transformer TR, Fig. 1, a diode D1 and a shunt resistance R1 are connected in the secondary circuit to prevent negative current flow during the negative phase of the control pulse, and a series combination of a diode D2, a small resistor R3 and a bias source is connected across the primary winding for facilitating A.C. magnetization of the transformer before the start of each control pulse and for providing damping of the induced oscillations that might arise from voltage peaks in the inverter. When a positive control pulse ceases, i.e. when transistor T is cut off, diode D1 prevents negative current flow in the secondary circuit feeding the valve (not shown) to be triggered. In the primary circuit, however, the induced negative voltage drives current through diode D2 and resistance R3 until the voltage decays exponentially to the level of the bias voltage EC2-EC1 when the circuit being open-circuited by the diode D2, discharge is permitted almost instantaneously. Resistance R3 provides large damping during the negative phase of the control pulse for any oscillations produced by the inverter circuit. In a modification a high resistance may be connected across Dl and in a further modification (Fig. 3, not shown) a separate bias EC2 is avoided by a parallel combination of a large capacitance and a resistance in series with a diode connected across the primary winding of the transformer.

A method of determining RNA distribution in vegetable or animal tissues, particularly during cell mitosis, comprises treating such tissue with methanol and HCL then with uranyl ions, and then with a basic dyestuff of the thionine group. In an example, after fixation, sections of tissue 3-5Á thick are split into two groups, the first of which is immersed in 0À1N HCL at 60 degrees for 20 minutes, washed, then dehydrated and combined with the first group. The sections are then passed through three baths of absolute methanol and immersed in absolute methanol containing 0À8 ml % of conc. HCl for 1 hour at 37‹C. This treatment blocks -CO 2 H and -OSO 3 Me groups present in the acid polysaccharides in the tissues. The sections are washed at least ten times in cool (5-8‹C.) water, immersed in a 0À5-1% uranyl acetate in 30% methanol solution for 1 hr. at room temperature, washed again at least ten times with cool water and maintained for 10 minutes at room temperature in a buffered methanolic solution. The sections are then passed into a freshly prepared solution of 5-10mg % toluidine blue in the buffer and left for 45-48 hours. They are afterwards washed, dehydrated and treated with Canada balsam or a synthetic resin and observed under a microscope.
