Title: Apparatus for simultaneously spraying granular materials and  a binder
IPC: E04F21/12
Filed: 1971-01-12
Abstract: 1334733 Spraying apparatus J VIGNOLLES 12 Jan 1971 [12 Jan 1970 30 Dec 1970] 1488/71 Heading B2L  Apparatus for spraying pulverent solid by means of air streams and mixing it with a binder material at the point of spraying comprises a hopper 1 with the pulverent material and a mixing spray head in which the various tubes are concentric. An adjustable butterfly valve 3 is provided at the base of the hopper and this allows the coating material to flow to an area 12. Air from a pump passing through a pipe 7 and pipe 11 removes the powder through a tube 4 which leads to the spray head. A binder material is taken from a reservoir by a pump 18 and fed through pipes 20, 21 to the spray head whence it mixes with the powder material. A separate pipe 22 carries air from compressor 23 to the spray head to provide an intimate mixing of the materials at the point of ejection. When spraying is finished the supply of binder is cut off and an electromagnet 10 closes a flap valve 9 against the end of tube 11 preventing the powder material from being further removed. The air from tube 7 then passes through a by-pass channel 13 and cleans any remaining material from the tube 4 and the spray head. In a modification (not shown) the apparatus is controlled and operated pneumatically.

Abstract: 534,318. Cathode-ray tubes. ELECTRICAL RESEARCH PRODUCTS, Inc. Jan. 25, 1940, No. 1510. Convention date, Feb. 21, 1939. [Class 39 (i)] In a television transmitter the photo sensitive elements 22 which receive the light image are supported on a perforated base 23 through which passes a scanning beam from a gun 12 to impact a transparent target electrode 25. Secondaries from the target electrode pass through the perforations in the base 23 to a collector electrode 21 to give the signal output, the flow of secondaries being controlled by the elements 22 ; these may be in the form of a mosaic in which case the target is a continuous metal layer or the elements may form a continuous layer 31, Fig. 3, the target electrode being then discontinuous. The base 23 is carried by the collector 21, these being movable within the tube 10 to facilitate coating the elements 22 ; the collector 21 has clips 27 bearing on the envelope and on the positively-biased electrode 20. The base 23 may be of glass or mica ; if of glass the perforations which are 650 to the sq. cm. may be made by coating one surface of a plate with wax dots, melting the wax so that only small spaces of the plate are uncovered, dipping the plate in an etching solution until the acid almost etches right through the plate and then etching from the other side. For a mosaic a layer of silver is deposited on the glass, this layer being broken up, oxidized and caesiated. The secondary electrode consists of a transparent film 26 of platinum heated to reduce its electrical resistance ; the mosaic and secondary electrode are kept about .05 m.m. apart by mica spacers 33. The electrode 26 may be used as the signal plate, or the coupling resistance 29, Fig. 3, may be connected to the collector 21. With a continuous photo emissive layer 31, Fig. 3, the base 23 may be of metal with 25,000 perforations per sq. cm. ; the base is insulated from the collector. Specifications 468,483, 498,867 and 510,696 are referred to. To form the photo sensitive layer the glass plate 23 and the collector are moved towards the gun 12 ; the tube is evacuated, baked and cleaned with hydrogen after cooling silver particles on the plate 23 are oxidized by an electrodeless discharge and after evacuation of the oxygen the silver oxide is reduced by hydrogen and subsequently oxidized again. After another evacuation the gun cathode is sensitized with BaO-SrO and then caesium vapour is introduced through the side tube 34 into the space between the plates 23, 26 ; the tube is baked at 200-225‹ C. and finally sealed off.

Abstract: 138,091. Domestic Engineering Co., (Assignees of Kettering, C. F.). Nov. 2, 1918, [Convention date]. Starting; turning-gear.-To enable an engine to be started upon heavy fuel, current is first supplied to a coil for heating the induction pipe and afterwards by an automatic switch to an electric starting-motor. In the arrangement shown in Fig. 1, a dynamo 23, in circuit with a battery 27, ampere-hour meter 28, and switch 35, serves as a motor for starting the engine 21 and as an enginedriven dynamo for charging the battery. When the current from the battery 27 falls off, an arm 40 on the meter 28 closes a switch 44 supplying current to a solenoid 46, which closes a switch 53 in the circuit of a coil 50 for heating the induction pipe 22 of the engine. After a time interval determined by a dash-pot 51, the plunger of the solenoid engages the lever 39 of the switch 35 and current is supplied to the starting-motor 23. When the engine starts and the motor is driven as a dynamo, the arm 40 moves away from the switch 14 and the plunger of the solenoid is returned by a spring 55. A hand-actuated switch 56 enables the solenoid to be actuated and the engine started independently of the meter 28. In a modification. Fig. 2, the solenoid and dash-pot are replaced by a motor 57 driving a cam 58, which first closes a switch 59 supplying current to the heater and afterwards actuates the arm 39 of the motor switch 35. In further forms, the switch 44 is connected directly to the heating-coil, and a switch supplying current to a solenoid for actuating the motor switch is closed by a thermostat adjacent to the heating coil or by a motor in series with the heating coil.

Abstract: 1432922 Automatic frequency control SONY CORP 17 Jan 1974 [23 Jan 1973] 02342/74 Heading H3A In an a.f.c. system for an electronically tuned receiver, an inhibit circuit 10 is included between the output of the frequency discriminator 7 and the tuned-circuit 1 to be controlled, which inhibits application of the a.f.c. signal for a predetermined time after switching on the receiver power supply. On initially switching on, FET 101 is rendered conductive by the voltage at the junction of capacitor 102 and resistor 103, to short out the a.f.c. signal. Capacitor 103 charges through resistor 103 until the voltage at the junction falls sufficiently to cut FET 101 off, thus enabling the a.f.c. circuit. The delay is sufficient to allow a channel selector voltage from potentiometer 14 to build up sufficiently to select the correct channel, thus preventing the a.f.c. from locking on to an incorrect channel.

Title: Installation for the automatic control of hydraulic jacks or like devices
IPC: G05B19/44
Filed: 1966-01-18
Abstract: 1,130,533. Hydraulic apparatus. BOTALAM. Jan. 18, 1966 [Oct. 22, 1965], No. 2364/66. Heading F1P. An installation for the automatic control of one or more hydraulic motors A1-A4 comprises reversing valves C1-C4, each controlling the supply and exhaust of fluid to one of the motors and each being operated by an associated cam D1 . . . D4 mounted on a cam-shaft E the stepwise rotation of which is controlled by a flow detector P adapted to close an electrical switch O when the flow from a source B to the motors is zero. The cam-shaft E carries a ratchet wheel F rotatable by a pawl J mounted on the movable rod K of a double acting jack L, the direction of movement of which is controlled by a changeover valve M operable by energization of electromagnets M1, M2 in circuit with the flow switch O. At the end of a cycle of operations of the motors a limit cam G opens a switch H to arrest the installation in a stop position. To initiate another cycle contacts R are manually closed whereby the electromagnet M1 is energized to cause reversal of the changeover valve M. Reversal of the valve M causes the rod K of jack L to extend and thus rotate the cam-shaft. Energization of the electromagnet M1 is maintained after the contacts R are opened, by closure of the contacts H. Since the motors are all in their end stop positions flow thereto does not commence until the cam D1 operates the reversing valve C1. The flow to the motor A1 operates the detector P thus opening the switch O and de-energizing the electromagnet M1. When the rod has completed its stroke it opens contacts Q1 and closes contacts Q2 to thereby energize the electromagnet M2 and changeover the valve M to cause the return of the rod K to the position in which contacts Q1 are closed. The return of the rod K stops the rotation of the cam-shaft until the motor A1 reaches its end position and the resulting termination of the flow closes the switch O to initiate further rotation of the cam-shaft.
