Title: Apparatus reducing the power for scanned display devices
IPC: H01J17/49
Filed: 1972-06-06
Abstract: 1381403 Matrix displays BURROUGHS CORP 6 June 1972 [21 June 1971] 26251/72 Heading G5C A circuit for a display panel having a matrix of cells coupled by crossed arrays of cathodes and anodes, comprises means for sequentially driving the cathodes for predetermined periods and means for reducing a bias potential applied to the anodes for part of the said periods. The panel is described in Specification 1,317,221. The reset cathode 110 and the first group of cathodes 111-1, 111-2... are pre-biased by a Zener diode 135 and resistors 106, 108 and 131 respectively. Cathodes 112-1, 113-1 ...in other groups are pre-biased by the current through resistors 132, 133 and diodes 142, 143 to the Zener diode. The scan anodes are pulsed by applying inverted clock pulses from an inverter 88 to transistor 90. During the clock pulse a high igniting potential is applied across the scan cells, this is reduced during the remaining period that the cell is actuated to reduce power dissipation. The display cells are operated only in the remaining period, initially the display anodes are held off by negative clock pulses at C applied to transistors 41 ... 45.

Abstract: 834,526. Coating webs. KODAK Ltd. Feb. 23, 1956 [Feb. 23, 1955], No. 26304/59. Divided out of 834,525. Class 140. Apparatus for applying two or more superposed coatings of layer-forming solutions, e.g. of light-sensitive material, to a film, paper, or other web comprises two or more chambers each having an extrusion passage communicating with a common discharge passage, and means for feeding the solutions to the chambers at controlled rates determined by the desired thickness of the individual layers. In Fig. 2 a hopper 10 is internally divided by an adjustable partition 16 into two chambers 24, 25 to which solutions S, S<SP>1</SP> are supplied by metering pumps P, P<SP>1</SP>. The chambers communicate with a discharge slot 11 through which superposed layers of solution L, L<SP>1</SP> are delivered to a bead 17 in contact with a moving web W, the layers being deposited on the web without intermixing. The hopper 10 is mounted on a frame which is pivoted about the web-carrying roller 13 and is adjustably securable by a screw engaging an arcuate slot.

Title: A machine for placing cork discs in caps
IPC: B21D51/46
Filed: 1925-10-21
Abstract: 264,592. Hohland, C. Joyko-. Oct. 21, 1925. Lathes.-Apparatus for inserting cork discs or liners in caps for collapsable tubes and for grooving the skirt of the cap to receive a loop of wire or the like comprises hoppers 1, 17 which receive the caps and discs respectively. A cam shaft 15 intermittently moves agitators 2 in the hoppers, from the spheroidal surfaces of which the caps and discs slide into grooves 3 rolling on their edges until they drop into chutes 6, 22 respectively. Guideways 105 receive the heads of wrongly-positioned caps and deflect them out of the chute as shown at 106, Fig. 10. A finger which propels the caps round the groove 3 is spring-pressed so as to pass by a jam of caps in safety. A compound slide 21, 31 coacts with the chutes 6, 22. When the slide is in retracted position, a previously lined cap drops into a pocket 32 and the lowermost disc 110 drops into a pocket 23, after which the slide is shifted from the position shown in Fig. 9 to that shown in Figs. 7 and 8, placing the disc opposite the lowermost cap in chute 6, which cap is supported by the upper surfaces of slide 31. As the slide approaches its limit of movement, a lever 28 moves a pin 25 rapidly so as to press the disc into the cap. The previously lined cap, now in the extended pocket 32, is grasped by jaws 33 for subsequent lowering by means of the carrier 44 into a position opposite a chuck 59 into which the cap is inserted by a pusher 61, this pin acting as a bearing for the cap while two grooving tools, one of which is marked 75, coact upon the skirted part of the cap. The parts 61, 75 are then retracted, and the tension of a spring 95 is increased bv a cam 98 to expel the finished cap from the chuck.

Title: Improvements relating to electrical circuits for indicating pulse frequencies
Inventor: CHAPPELL EDGAR RAYMOND REGINAL
IPC: G01F1/90
Filed: 1957-08-21
Abstract: 832,412. Electrical measuring systems. SIMMONDS AEROCESSORIES Ltd. Aug. 13, 1958 [Aug. 21, 1957], No. 26398/57. Class 40 (1). In a pulse-frequency measuring circuit the pulses are fed to a diode pump having a resistance shunting the integrating capacitor, an indicator is coupled via an amplifier to the integrating capacitor, a manually-variable resistor capable of being set in accordance with the density of a fluid and a thermistor network capable of responding to the fluid temperature being provided to render the indicator responsive to rate of mass flow of the fluid. As shown, a transducer S such as that described in Specification 803,069, generates a signal, the frequency of which is proportional to rate of volumetric liquid flow. This signal controls the frequency of a pulse generator 1 the output of which is fed to a diode pump circuit comprising capacitors 2, 3 and diodes 4, 5. The capacitor 3 is shunted by two resistors 6, 8 so that the voltage across capacitor 3 is dependent on the frequency. This voltage is amplified by valve 10 before controlling the anode current of valve 11, as shown on an indicator 14 calibrated in rate of mass flow. Adjustment for liquids of different density is made by a calibrated potentiometer 13. Variation in density due to temperature change is corrected by a thermistor 7 located in the liquid. Either or both the thermistor 7 and the potentiometer 13 may alternatively be connected in the divider chain 1a (and hence vary the pulse frequency and/or amplitude) or in series with resistor 16. The sum of the rates of fluid flow in two pipes may be measured by using two such circuits with a common indicator 14 and potentiometer 13. A pulse counting circuit such as that described in Specification 832,411 may be connected to unit 1 to measure the total mass of fluid used.

Briquettes (not shown) of carbonized coal dust are fed through a seal and rotary feeder (not shown) at 9 into basket-like buckets 5 of an endless conveyer 4. The latter extends through a succession of chambers 10, and the briquettes are subjected to a coolant or annealing medium (steam, water vapour, or inert gas) fed from nozzles 13 (Fig. 2). The baskets are dowsed in a hot quenching bath 12 which also forms a water seal prior to an air-hardening section 23 associated with the lower run of the conveyer. A main quenching bath 22 then precedes an open maintenance area 24. The baskets are tilted, by the action of a cam surface 28 engaging rails 27, to discharge the briquettes on to a cross-conveyer 31.

Title: Improvements relating to the production of artificial threads

IPC: D01D5/20
Filed: 1957-08-26
Abstract: <PICT:0860684/IV (a)/1> In a process for the manufacture of slub yarn spinning liquid is extruded from a jet supplied from a metering pump through a resilient reservoir in series with a second pump of different capacity from that of the metering pump, and which is intermittently by-passed.  As shown, the process may be carried out using apparatus comprising a metering pump 2 connected to a jet 6 through resilient reservoir, e.g. candle filter 5, in a resilient case in series with a second pump 3 of different capacity from that of pump 2 and an intermittently operated valve 4 which permits spinning liquid to by-pass pump 2.  The spinning liquid may be viscose.  Two types of apparatus are possible, i.e. in which the capacity of 2 is greater than 3 and vice versa.  In operation of type 1, with both pumps working and valve 4 closed, basic denier lengths are extruded from jet 6, whilst the volume of liquid between the pumps increases thereby expanding the resilient reservoir.  When the valve is opened, reservoir 5 contracts, expelling liquid through the by-pass to the output side of pump 3, rate of extrusion increases and alubs are formed.  In operation of type 2, when both pumps are working and valve 4 is closed, slubs are extruded and the volume of liquid between the pumps becomes depleted, thereby causing contraction of reservoir 5.  When valve 4 is opened, reservoir 5 expands towards its normal capacity, thereby drawing liquid from the discharge side of pump 3 via the by-pass into the part of the apparatus between the pumps.  The rate of flow of liquid through the jet is thus reduced and basic denier lengths are extruded. Specification 811,128 is referred to.
