Patent GB-971075-A (GB)
Title: Improvements in and relating to solid-fuel combustion appliances
Inventor: COLLINS KENNETH EDMUND
IPC: F23K3/14
Filed: 1960-06-14
Abstract: 971,075. Controlling combustion of solid fuel. C.U.R.A. PATENTS Ltd. Sept. 14, 1961 [June 14, 1960], No. 20900/60. Heading F4B. [Also in Division G3] In the solid fuel combustion apparatus disclosed in Specification 947,205, there is provided a control for the fuel supply regulator which is responsive to two temperatures, e.g. the temperature of the water in a hot water system, and the outside temperature, the control causing the regulator to tend to increase the fuel supply rate when the first temperature falls, and vice versa, and, causing the regulator to tend to increase the fuel supply rate when the second temperature falls, and vice versa. As shown, the two control temperatures are those of phials 85, 85A, situated respectively in a boiler water pipe and on an outside wall. Capillary tubes 84, 84A run from these phials into the top of a bellows box 82 with a bellows 81 forced down by an increased water pressure, when either of the phials is heated, against a spring 83, causing a rod 80 to act against the head 79 of a spring-loaded rod 76, thus moving a push-rod 73 up against the end of a bimetallic strip 65, pivoting this strip about the centre 67 of a rigid bar 66, and hence moving a contact blade 70 farther away from the fixed contact 72. Operation.-When the switch contacts 71, 72 are closed, a contactor 87 operates to energize a motor operating a chain grate (not shown). The temperature of the bimetallic strip 65 is increased by the heating of a coil 86 wrapped around it, and the rods 65, 66, 68 start to pivot about 67. Eventually contacts 71, 72 are opened, and the motor is de-energized. As the temperature in the phial 85 increases, push-rod 73 rises, causing the contacts to open at a lower temperature. As the temperature in the phial 85A falls, the opposite happens, and the pushrod 73 drops. In a second arrangement (not shown), a heating coil is placed around the phial 85A, in series with the switch, which is arranged to close when the volume of liquid in the phial, tubes and bellows box rises, and vice versa, by arranging the bellows 81 and the rod 76 on the opposite side of the lever to that shown, and by means of a reverse-acting relay which is arranged to cause the motor to be energized when the switch is open and vice versa.

Title: Process of chemically transforming photographic silver images
IPC: G03C5/40
Filed: 1929-07-08
Abstract: 333,361. Lierg, F. July 8, 1929. Toning.-In a process for transforming the silver of photographic images into other compounds, the silver is first converted into an insoluble compound, e.g. silver halide, which is then treated with a solution containing a complexforming solvent and a re-agent which immediately reprecipitates the silver as an insoluble compound. Examples of complex-forming solvents used are, manganic thiocyanate and compounds of the carbamide and thiourea groups, e.g. thiosinamine. The insoluble reaction products may be produced by the addition of potassium ferrocyanide, Seignette salt or sodium phosphotungstate. If sulphonic acids, e.g. hydracid 1.8-anidonaphthol- 3.6-disulpho acid, are used a silver compound of the acid is produced which may be converted into an azo dyestuff. If thiocarbamide is used with a silver compound insoluble therein, a resin-like substance is formed which renders the gelatin water-repelling in the neighbourhood of the image, the unprotected gelatin being then dyed to yield a negative dye image. Specifications 21584/06,. 132,846, 245,163 and 279,381 are referred to.

Patent GB-202653-A (GB)
IPC: H03B5/10
Filed: 1923-08-18
Abstract: 202,653. Ritscher, W. Aug. 18, 1922, [Convention date]. Thermionic oscillation generators; heterodyne receiving systems.-Thermionic valve circuits for generating oscillations in a transmission system, a heterodyne receiving system, or for other purposes, comprise an oscillatory circuit connected at different points to the three valve electrodes, the anode connection including a variable condenser which tunes the circuit from plate to filament to a quarter of the wave-length of the oscillations produced, or to a multiple thereof. In the circuit shown in Fig. 1, a coil 11 partially shunted by an adjustable condenser 10 is connected at its ends by adjustable condensers 9, 18 to the grid 7 and plate 8 respectively. A tap 21 on the coil 11 is connected to the filament 6, and the plate 8 is connected through a transformer primary 16 and battery 13 to the filament. A telephone 17, connected in the secondary circuit of the transformer, enables a beat note, due to interference between incoming waves and the waves generated in the circuit 10, 11, to be heard. In a modification intended for the simple generation of oscillations, the transformer 16 is replaced by a resistance, and the grid condenser 9 is omitted. In both cases, the condenser 18 is adjusted to tune the plate-filament circuit, comprising the condenser 18 and the upper part of the coil 11, to the wave-length mentioned above. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter. The double frequency obtained by coupling two tuned oscillatory circuits is reduced to a single frequency by connecting the oscillatory circuits to the electrodes of a triode valve in such manner that for one frequency the oscillations are sustained whilst for the other frequency the oscillations are damped out. Fig. 1 (Cancelled) shows diagrammatically two tuned circuits 1, 2 consisting of three impedances 3, 4, 5, adjustable connections being made from these impedances to the electrodes 6, 7, 8 of a triode valve 20. In a further modification shown in Fig. 5 (Cancelled), an aerial 21 is earthed through a condenser 10 and an inductance coil, the aerial side of the condenser 10 being connected through a coil and condenser 18 to the valve plate 8, and a tap on the aerial coil connected to the grid 7, the filament being earthed and connected through a battery 13 to the plate 8. When the oscillator is employed for heterodyne reception, the sustained oscillations are utilized as the local frequency, whilst the damped frequency is made equal to that of the received waves. This subjectmatter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 139,640, 147,446, 149,195, 172,127, and 182,168.

Title: Improvements in or relating to television transmitting apparatus
Inventor: THEILE RICHARD
IPC: H01J31/26
Filed: 1951-09-06
Abstract: 741,592. Television. PYE, Ltd. Sept. 8, 1952 [Sept. 6, 1951], No. 21084/51. Class 40 (3). Television transmitting apparatus of the type described in Specification 656,069, in which scanning of the target 8 of an image iconoscope is effected by a flying spot scanner 1 scanning the same area of the photo-cathode 6 as that on which the image 16, is projected, is arranged whereby a slide or kinematograph film 17 may be positioned in front of the flying spot scanner so that the apparatus can be operated either as a conventional flying-spot scanner or as a storage type pick-up tube. When operated normally, the light from the scanning spot is projected directly on to the photo-cathode together with the light from image 16, and the output is derived from across the target electrode resistor 12 through amplifier 14. When operating as a flying spot scanner, the slide or film 17 is positioned in front of scanner 1 and the light from image 16 is cut off. For this mode of operation, the pick-up tube functions as a simple photocell, the output being derived from the photocathode current collected by electrode 11. The current flows through resistor 18 and the fluctuations are amplified in amplifier 19. When operating as a flying spot scanner, the focus coil 10 is preferably not energized. By interposing a slide or film in the scanning light beam whilst the photo-cathode is simultaneously exposed to image 16 a composite signal may be derived from the target output. According to a feature of the invention, the target may be made semitransparent by the use of a mica sheet backed by a semi-transparent metallic film. By this means, the photo-cathode may be illuminated from the rear. Thus, as illustrated, a transparent slide 16<SP>1</SP> may be projected simultaneously or alternatively with image 16 or the film 17. This arrangement may be used for projecting captions during intervals between film transmission, switching means being operated upon starting up the film feeding mechanism to deenergize the focus coil. In a modified arrangement, Fig. 2 (not shown), the pick-up tube includes two electron multiplier arrangements constructed as described in Specification 721,943 and serving respectively to multiply the electrons released from the target and photocathode. The tube employed in this modified arrangement forms the subject-matter of Specification 741,649, [Group XL (a)].

Title: Pumping apparatus eg for gas-free liquids
IPC: F04D29/70
Filed: 1972-05-05
Abstract: 1395215 Fluid-pressure servomotor systems J DELSUC 5 May 1972 [7 May 1971 11 April 1972] 21117/72 Heading G3P [Also in Division F 1] A centrifugal pump 30 draws liquid from a container 1 via a valve 40 comprising a valve member 43 carried by a spindle 42 and urged against a seat 47 by a spring 46 and away from the seat by a float 8. A rolling diaphragm 45 connected to the spindle 42 is subjected, via a pipe 62 and a further valve 50 closed by a float 58, to the liquid pressure within the container 1 when the valve 50 is open or to the pressure within the pump volute 34 when the valve 50 is closed, the valve 50 being connected to the volute for this purpose by a pipe 61. When, as a consequence of a fall in the liquid level in the container 1, the valve 40 is closing, the valve 50 is already in the open position, whereby the diaphragm 45 is subjected to the low pressure within the container instead of the pump discharge pressure at the volute 34. This assists the closing of the valve 40. If the liquid level begins to rise again, the action of the float 8 is initially insufficient to re-open the valve 40, but when subsequently the float 58 closes the valve 50, the diaphragm 45 then becomes subjected once more to the pressure at the volute 34 and assists the float 8 in re-opening the valve 40.
