Filed: 1919-05-24
Abstract: 139,373. Calico Printers' Association, Schofield, E., and Farnworth, F. May 24, 1919. Spraying travelling materials.-Relates to improvements in the method of and means for producing marbled, veined, or variegated colour effects on textile and other materials such as paper, and consists in first daubing or similarly applying colour to one side of the material, and subsequently applying colour to the other side by allowing it to drip or drop on to the material. For this purpose, the material b is led over guiderollers and under an adjustable pressure roller c across the machine to a pair of rollers t, t<1>, whence it passes to the rollers of a drying-machine, by which it is drawn through the dyeing-machine. The first colour is applied to the underside of the material bv brushes h' mounted in a rotating frame h driven by gearing from the shaft k. The brushes pick up colour from the box i, which may be a continuous trough or sectional for supplying different colours. The brushes may be arranged to form a pattern, and pads or other rotary appliances may be used instead of brushes. The second colour or series thereof is supplied to the other side of the material from cans l, in a frame m, each having delivery taps n, o controlling the supply of colour to troughs p, p<1> on bars q, q<1>, which may be actuated to traverse the trough transversely. The troughs p, p' have drip taps p<2> to allow a regulated flow of colour to drip on to the material. Catch troughs r, r' operated 'by hand or automatically may be interposed between the taps and the material. Surplus colour is removed on the chain-driven rollers t, t<1> by doctors v, v<1>. One or both of the rollers t, t' may also be reciprocated. If liquid wax is to be dropped on to the material, means are provided for maintaining this resist at the required temperature.

Filed: 1946-05-01
Abstract: 611,564. Frequency and phase modulation; automatic gain control. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 1, 1946, No. 13239. Convention date, May 2, 1945. [Class 40 (v)] In frequency or phase modulation reception, a stronger desired signal is received with -a minimum of interference from a weaker undesired signal on the same carrier, by applying the received carrier through selective and frequency-changing stages to the grid of a lockedin oscillator which feeds the discriminatordetector; and the strength of the carrier applied to the grid is maintained by A.V.C. methods at a constant critical value at which the inter - ference is a minimum. The incoming wave is received on the aerial 9 and passes through amplifier 5, heterodyne stage 6, 7 and I.F. amplifiers 8, 81 from which the I.F. is fed through tuned coupling 11 to the inner control grid of a heptode 40. The anode and the outer control grid of the valve 40 are backcoupled at 42 to generate oscillations at a fraction (say one-fifth) of the intermediate frequency, but locked in step therewith and following the I.F. deviations. The tuned anode circuit feeds a discriminator-detector 14 followed by audio amplifiers. The A.V.C. circuit branches between the amplifiers 8, 8<1> and feeds a diode 17 through an amplifier 41. The load resistor 19 is shunted by high resistors 53, 28 and positive delay bias is applied from a source E to the junction 54. The A.V.C. voltage at the junction is applied to the grids of the stages 5, 6, 8 and a smaller adjustable bias is applied from a slider 29 to the grid of the second I.F. stage 8<1>, the slider being adjusted until the voltage across the grid resistor 12<11> is flat. In a modified A.V.C. rectifier circuit, Fig. 2 (not shown), the delay, bias is applied to the diode cathode which is earthed through a condensershunted resistor. The cathode is also connected by a condenser to the tuned input circuit 20 which is earthed through the potentiometer 28. Full A.V.C. voltage is applied to the stages 5, 8 and adjustable partial voltage to the stages 6, 8<1>. Specification 562,993 is referred to.

Title: Improvements in means for emptying refuse receptacles
IPC: B65F3/12
Filed: 1936-05-12
Abstract: 458,653. Scavengers' vehicles. HIRSCHNER, K., Weidenan, Sieg, Germany. May 12, 1936, No. 13412. [Class 108 (i)] Emptying refuse bins. The bin is raised by tilting until it rests against the hinged cover c of a vehicle or storage chamber with the projection on its hinged lid p engaged in the corresponding recess in the hinged door d of the cover. Further tilting then rotates the cover c about the pivot k. This causes the hinged links b, i to pivot about the fixed point m and thus, through the agency of the connecting spring g, causes the hinged door d to rotate about the pivot a away from the cover c, carrying the hinged lid p with it during the process and thus opening the bin. The arrangement of the spring allows the door d to yield in the event of meeting an obstruction while closing.

Title: Improvements in or relating to automatic starting systems for engine driven electricgenerators
IPC: F02N11/08
Filed: 1946-05-03
Abstract: 618,877. Self-contained supply systems. LISTER & CO.,.Ltd., R. A., and ATTWOOD, F. A. May 3, 1946, No. 13530. [Class 38 (iv)] Fixed-speed generators, with.-In an automatic starting system for an engine-driven alternator in which a starter battery is connected through a load relay to the idle load circuit the load relay when energized by current in the load circuit disconnects the battery from the load circuit and connects to it the alternator at the same time operating a starting contactor to connect the battery to a starter motor which may subsequently charge the battery. Under no-load the battery 13 is connected through the alternator to the load 16 through the contact 20 of a change-over contactor 22 and the closed contact 42 of a battery isolator switch 40. Any load energizes relay 15, whereby contact 24 is closed on contact 23 and the change-over contactor 22 energized from the battery so long as any load is connected. Contactor 22 opens the contact 20 and closes the lower one to connect the alternator to the load circuit, closes contact 25 to energize fuel and compression control coil 27 and closes a contact whereby the starting contactor 18 is energized and its contact 34 closed to connect the dynamotor 12 to the battery and start the alternator set. At a given exciter voltage a relay 28 closes a contact to bring the exciter and alternator to full voltage, the relay also opens contact 31 to deenergize the starting contactor. The dynamotor becomes reconnected to charge the battery through cut-out 35 closing. Relay 28 also closes a contact to connect the excitor in parallel with the battery, and a contact 32 in circuit with a thermal oblong switch 33. During starting a thermal switch 41 is operative to energize a coil 40 on failure to start ; the coil 40 opens a contact 42 which de-energizes the coils 18, 22 and 27 and prevents further action. The load relay is protected against heavy load currents by a second relay 37 operating a short-circuiting contact 38 ; a third load relay may be used. The relay 15 on releasing closes the heating circuit of the thermal delay switch 33 at the lower contact of 24 to short-circuit coil 22 after an interval and cause shut down of the alternator and return to the original condition of the system. A modified system is described wherein a polarized relay responsive to the current flow between battery and dynamotor replaces the relay 28.

Abstract: 342,222. Induction motors. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13A, Emmasingel, Eindhoven, Holland. May 3, 1930, No. 13680. Convention date, May 16, 1929. [Class 35.] Alternating-current; insulation.-In Rontgenray tubes with anticathodes rotated by or forming the rotor of an electric motor with its stator outside the tube, the electric field in the air-gap between the stator magnets and the wall of the tube is avoided or limited, either by suppressing the air-gap or by reducing the field in it by electric screens. Damage to the wall of the tube consequent on ionization in the air-gap is thus avoided. The external field system may be rotary, or may be stationary and supplied with polyphase current or with singlephase current through phase-shifting devices. The stator 17, Fig. 1, may be arranged in an earthed casing 16 filled through a screwed orifice 21 with an insulating compound or oil to suppress the air-gap. The centre of the secondary supplying the electrodes 5, 8 is also earthed. In a modification, the air-gap is avoided by making the stator cores 15 of chromeiron containing 20 per cent chromium and fusing the cores 15 to the glass wall 1. In other modifications, the field in the air-gap is neutralized by screens which may be connected electrically to the cores 15 ; the metal wall 3 at the centre of the tube may be extended beyond the stator 17, or conducting plates or a thin layer of chrome-iron may be fused into the glass 1, or a screen 23, Fig. 2, may be provided inside or outside the wall 1, preferably by applying tinfoil to the wall or by disintegrating metal on to it.

Title: Radio beacon transmitting apparatus
Inventor: PIERCE REGINALD ROY
IPC: H04B1/034
Filed: 1961-04-17
Abstract: 1,025,101. Amplitude modulated radio transmitters. VIDOR HOLDINGS Ltd. April 17, 1962 [April 17, 1961], No. 13786/61. Headings H3R and H4L. [Also in Division H2] An amplitude modulated radio transmitter for use in radio beacon apparatus, comprises a crystal controlled transistor oscillator size 1, a frequency doubler valve amplifier stage II and a frequency doubler valve power amplifier stage III. The signal is amplitude modulated by providing the valves with a square-wave pulsed H.T. supply, via a half-wave rectifier 36, from a push-pull transistor oscillator stage IV comprising PNP transistors 28, 30 and a saturable transformer 3 including primary, output and feedback windings 33, 34 and 38, respectively, operating at a frequency of 1 kc. The positive battery tap on the primary winding of the transformer is positioned so that transistor 30 conducts for three times the conduction period of transistor 28, hence the oscillator output square waveform is asymmetric and the transmitter valves provide maximum output for three-quarters of each modulation cycle. The stage IV is triggered on for 0À5 seconds and off for three seconds by an astable multivibrator 40, comprising transistors 39, 41, and a switching transistor 42 which periodically supplies forward bias to the bases of transistors 28, 30 to overcome the reverse bias provided by battery 44. During the periods between pulses and when stage IV is triggered off, the valves are supplied from a 12-volt battery source connected in series with output winding 34 and transmit c.w. at low power.
Patent GB-197199-A (GB)
Title: Improvements in catalysts more particularly for the synthesis of ammonia
IPC: C01C1/04
Filed: 1922-05-16
Abstract: A catalytic material is prepared by injecting oxygen under pressure into heated iron or an alloy of iron with manganese, chromium, molybdenum, tungsten, carbon and the like, until the mass is brought into a state of violent ebullition and part of the oxidation product is vapourized away.  Any impurities present in the starting material which are detrimental to catalysis are thereby eliminated.  The cooled product may be reduced to the metallic state with hydrogen or nitrogen-hydrogen mixture.  The catalysts are for use more particularly in the synthesis of ammonia, but may be employed for other catalytic operations such as the oxidation of ammonia to nitric acid or of carbon monoxide to carbon dioxide or for the production of hydrogen from water and carbon monoxide.  The process may also be applied to the regeneration of iron or iron alloys whose catalytic efficiency has become impaired.  According to the example, oxygen is forced through a hole in the bottom of a magnesia crusible containing turnings of impure iron or molybdenum steel together with lime, the turnings being heated to a temperature below that of fusion; the reaction proceeds with almost explosive violence and is stopped when 5 to 15 per cent of the oxidation product has been eliminated by the excess of oxygen; on cooling, the resulting iron oxide is crushed and either used as such or reduced to the metal.ALSO:A catalytic material is prepared by injecting oxygen under pressure into heated iron or iron alloy until the mass is brought into a state of violent ebullition and part of the oxidation product is vaporized away.  Any impurities present in the starting material which are detrimental to catalysis are thereby eliminated.
