Title: Multiple-acting rotary pumps
IPC: F04C2/344
Filed: 1920-11-03
Abstract: 153,327. Schmied, W. Nov. 4, 1919, [Convention date]. Fixed-abutment types; cooling; packing; plant. -Comprises a rotary pump having at least two working chambers. Fig. 1 shows a stator 1 having three cylindrical bores 3, 4, 5, the bore 5 being of somewhat greater diameter and forming abutments for the rotor 2. Sliding vanes 10 are arranged in slots 9 tangential to a circle 8 and normal to the stator at the outlets 7. They are in contact with the stator under the action of centrifugal force, and their number is such that one at least always bears on each of the abutments 5 to ensure fluid tightness. In addition, spring- pressed members 11 may be provided for this purpose. Fig. 2 shows a form having a cooling sleeve 13, outside of which are channels 14, 15 in two different planes connecting the inlet opening 18 with the inlets 6, 6, of the chambers and the outlets 7, 7 of the chambers with the outlet 19. The form shown in Fig. 1 may be used as a double-stage pump by arranging the two chambers in series. If the second chamber is of smaller dimensions, the machine may be used as a twostage compressor. For higher pressures, two machines may be used, the first working in parallel and the second being a single-acting machine; this allows rotors of the same size to be used, and if coupled directly will both run at the most efficient speed. A cooling apparatus may be directly inserted between the machines.

Filed: 1948-12-03
Abstract: 658,793. Conveyers. ROSE BROS. (GAINSBOROUGH), Ltd. Dec. 3, 1948, No. 31303. [Class 78 (i)] [Also in Group V] Plastic material, e.g. ice cream, is continuously extruded on to a support 12 from a device 13, and is cut into blocks by a vertically reciprocating framework 17 having a knife 14 carried in a support 26, which support is moved to and fro parallel to the travel of the extruded material, by a link 27 in known manner, at substantially the same rate as that of extrusion of the rod of material 11. The cut blocks 16 pass on to a belt conveyer 28 driven at a greater rate than the rate of extrusion, so as to space out the blocks which are then carried through a freezing chamber 31 (in the case of ice cream) to a transfer station. At this station the blocks are moved on to a conveyer 46 which may be either of the simple belt type or have a series of spaced pushing elements each adapted to forward a block along a feed channel towards, e.g., a wrapping machine. When a pushing element conveyer is used the operation of the conveyer is in timed stepped relationship with the transfer member 43 to receive the blocks.

Title: Improvements in and relating to tobacco feeding mechanism for cigarette making machines
IPC: A24C5/14
Filed: 1937-11-16
Abstract: 503,558. Cigarette-making machines. AMERICAN MACHINE & FOUNDRY CO. Nov. 16, 1937, No. 31449. Convention date, July 2. [Class 130], In a continuous-rod machine, tobacco showered on to a conveyer travelling at the speed of the cigarette rod is subjected to an axial compacting action while confined between the conveyer and a tobacco engaging element spaced from the conveyer and travelling in the same direction but at a greater speed. As shown in Fig. 2, a picker roller 26, co-operating with a shroud 27, removes tobacco from a feed drum 22 and projects the stem portions S into a detachable receptacle 28 having an adjustable rear wall 29. The lighter portions T<11> fall on to a belt 31 and are showered down a shoot 11 on to an endless belt 13 which passes around a groove in a forming wheel 16 mounted on a shaft 17 at one end of the shoot. A roller 36, Fig. 1, prevents escape of tobacco from the shoot. The tobacco is confined in the groove by a belt 50 which feeds the paper web P and passes over and drives flanged wheels 37 loosely mounted on the shaft. The shaft 17 and belt 31 are driven at a faster speed than the belt 50 and paper strip to effect an axial compression of the tobacco filler, and the speed of the shaft 17 is controlled by a regulator 46 which adjusts ' the speed of an electric motor. As the belt 31 leaves the wheel 16 a pair of grooved compressing wheels 71 geared together turn its edges inwardly to impart-an oval cross-section to the filler. A second pair of grooved compressing wheels 76 geared together compact the rod to a circular cross-section before it is fed to the rodforming mechanism .71a. The peripheral speed of the wheels 71, 76 is equal to the linear speed fo the belt 50.

Abstract: 940,013. Electronic counters. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 17, 1962 [Aug. 21, 1961], No. 31689/62. Heading G4A. [Also in Division G1] The invention relates to a binary counter in which each bi-stable pair comprises two storage electroluminescent elements and two triggering electroluminescent elements. Inthe Figure the arrows indicate optical couplings when the electroluminescent elements concerned are radiant. Assuming that element 1 of stage T1 is initially radiant then a pulse from photoconductor 9 causes element 6 of T3 to irradiate photoconductors 7 and 2, so reducing their resistances whereupon stage T2 turns on after a short delay with extinction of T1. Stage T3 or T4 is used for control of the next bi-stable pair.

Title: Induction motor speed control
IPC: H02P25/32
Filed: 1958-10-06
Abstract: 841,342. Control of A.C. motors. LEE, W. H. Oct. 6, 1958 [Nov. 7, 1957], No. 31798/58. Class 38 (3). [Also in Group XXXV] The firing-periods of thyratrons 21-26, which determine the rotor impedance of an induction motor M, are controlled by varying the D.C. component of the grid voltage whilst the phase relationship and amplitude of the A.C. component is maintained substantially constant. A network for providing the lagging grid voltage for the thyratron 21, for example, comprises a capacitor 30 and resistor 31 which are connected in series across the anodecathode circuit of the valve, a lead 32 from junction-point 34 extending to the grid through resistor 33. A capacitor 35 is connected across the grid and cathode whilst a small capacitor 36 may be placed across the resistor 31. The D.C. bias to control the level of the grid voltage is derived by impressing a signal between the neutral point N of star-connected resistors 38-40 in the rotor circuit and conductor B which is connected through resistor 41 to point 34. To overcome instability when heavy anode currents are being controlled, the grid resistor 33 is enlarged and is shunted by the gridcathode capacitor, a further small grid-cathode capacitor being added to increase the phaseshift. The D.C. bias may be controlled manually by means of a rheostat, or automatic control may be afforded by apparatus comprising a tachometer generator the output of which is compared with a reference voltage.

Title: Improvements relating to the automatic tuning of radio receivers
IPC: H03J7/04
Filed: 1935-11-18
Abstract: 465,827. Wireless receiving circuits. COLE, Ltd., E. K., and BRADFIELD, G. Nov. 18, 1935, No. 31848. [Class 40 (v)] In order to overcome the tendency of the automatic frequency control of a radio receiver to overshoot to an appreciable extent the true centre frequency, the characteristic curve which relates oscillator frequency change to grid volts change of the tuning valve is made closely to follow the curve relating control potential and frequency off resonance of the control system. The Figure shows a superheterodyne receiver in which the intermediate frequency output from the frequency changer V1 is applied over a selective coupling T1 to a second frequency changer V2 the oscillations of which beat with the first I.F. to produce a beat frequency of, e.g. 20 kc. while the ordinary signal is passed over transformer T4 to the right hand signal diode of V3 and thence through amplifiers V4, V7 to the loudspeaker, the 20 kc. beat frequency is applied from winding P2 and secondary So to the left-hand diode of V3 for the purpose of deriving A.V.C. voltages for valves V1, V2, and also from secondary S to the control grid of amplifier V4, from the anode circuit of which this beat frequency is applied to diode V5 over transformer T7 sharply tuned to 20 kc. frequency ; T6 is less sharply tuned to this frequency, the rectified output of V5 across R3 is applied over R4 to the outer control grid G3 of a thermionic reactance or tuning valve V6 which varies the frequency of the oscillator circuit of V1 in accordance with changes in its mutual conductance. The effective reactance of this valve is also varied for different wavebands by switch S2 which is ganged with the waverange switch to ensure equal effectiveness of automatic tuning over the two wavebands. The grid G3 of V6 may be connected either to the bias resistor R7 through a switch S4 or to a point on potentiometer R8 through R5, R6. When S1 is closed S1, S4 are operated by the tuning knob, S 4 being closed during manual tuning; S1 is open when C4 is closed and vice versa. Thus when S4 is closed the automatic frequency control bias is inoperative as regards V6, while with S1 closed and S4 open, two separate bias voltages, are applied to the grid G3, one being the A.F.C. bias from resistance R3, the other a momentary bias due to discharge of condenser C1 which gradually falls until the entire control is derived from R3, the tuning point of equilibrium being thereafter reached when this voltage equals that required by V6 for its frequencycorrected position. The switch S3 is adapted to close when S4 opens, and inserts a condenser between the coupling T1 to increase the coupling when the receiver is in tune.
