Title: Improvements in or relating to moulds for use in the manufacture of chocolate confectionery
IPC: A23G1/22
Filed: 1936-08-26
Abstract: 480,701. Moulds for chocolate. LE CERF, H. Aug. 26, 1936, No. 23420. Convention date, Aug. 26, 1935. [Class 87 (ii)] .

Title: Improvements in and relating to television apparatus
IPC: H04N5/21
Filed: 1952-09-18
Abstract: 713,921. Television. GENERAL ELECTRIC CO. Sept. 18, 1952 [Sept. 20, 1951], No. 23459/52. Class 40 (3). [Also in Group XL(c)] In an arrangement for separating synchronizing signals from a composite television signal the latter is fed to a pair of oppositely poled unidirectionally conducting paths connected in parallel each path having a different circuit impedance value and from one of which the desired synchronizing signals are obtained. Fig. 1 shows one embodiment in which the synchronizing signals are obtained across a resistor 33 which forms the circuit impedance of one of two parallel connected oppositely poled diodes 26, 27, 28, 29 to the electrodes 26 and 29 of which the composite signal is fed with negatively going signals via resistor 30 and condenser 31 from the video amplifier stage 15 of a television receiver. By suitable choice of the ratio of resistor 33 to resistor 32 (which forms the circuit impedance of the second diode) it can be arranged that the composite signal is divided in the region of the synchronizing signals so that the latter are developed across resistor 33 (and the vision signals across resistor 32). The separated synchronizing signals are then fed to a limiter 34 and thence to a conventional line/frame synchronizing signal separator 19. Noise pulses such as 47, 47<SP>1</SP> appear in the output of limiter 34 as pulses 47" and these, since they are of shorter duration than the synchronizing pulses 42", may have their amplitude, relative to the amplitude of the synchronizing pulses, altered by means of an integration circuit (not shown) to facilitate separation from the synchronizing pulses. By supplying the control grid of picture reproducing tube 17 from resistor 32 instead of directly from the video amplifier 15 the need for an additional D.C. restorer is avoided, Fig. 4 (not shown). Specification 538,103 is referred to.
Patent GB-234706-A (GB)
Abstract: 234,706. Carter, C. W. Nov. 11, 1924. Automatic-feed weighers. - In a machine for automatically regulating and maintaining a flow of grain or other material, for example, at a predetermined number of pounds per.hour, and comprising flow control mechanism, a flow actuated device and a power device acting under the control of the flow actuated device to adjust the flow control mechanism, the flow control mechanism is in the form of a gate or weir behind which the flowing material piles up at its angle of repose and over which the material flows. The material flows over a sliding gate 16, Fig. 3, and impinges against an inclined plate 28 carried by a lever 27. A central ridge on the inclined plate spreads the flow of material. Rigidly attached to the lever is a scale beam 33, Fig. 1, graduated for poise settings of pounds per hour flowing over the gate. Below one end of the scale beam, and freely mounted on a shaft 21, is a forked arm 44 continuously oscillated by a power-driven crank 58 and connecting rod 59. The forked arm 44 carries two spring-pressed pawls 45, 46 which, in the position of equilibrium shown in Fig. 1, are prevented from engaging a ratchet wheel 40 by the interposition of a gapped segment 53 frictionally connected with the forked arm. The gapped segment is integral with an arm 52 having an inturned extremity 52<1> which, in the position shown, oscillates, uninfluenced, between two stationary stops 55 and between two escapement stops 60, 61 carried by the beam. If the flow of material over the gate 16 varies, the beam tilts and one of the escapement stops 60, 61 intercepts the oscillating arm 52 thus displacing the gapped segment 53 and allowing one of the pawls 45, 46 to rotate the ratchet wheel 40 through one tooth. The ratchet wheel rotates a pinion 20, Fig. 3, and the gate 16 is moved to restore the normal flow. At the completion of its return oscillation the arm 52 together with its segment 53 is restored to normal position by contact with one of the stationary stops 55 the action being repeated if the flow has not been sufficiently altered. In the event of the gate being moved to an extreme position, due for example to shortage of material, a lug 68 on the ratchet wheel 40 engages an electric contact 67 and an alarm gong 66 is sounded, and at the same time a toothless portion 40<1> of the ratchet wheel comes opposite the pawls 45, 46 and renders them inoperative. An agitating or feeding device consisting of a drum fitted with peripheral blades may be arranged within the hopper. In a modification, instead of employing the oscillating forked arm 44, a reversible electric motor is used to move the feed gate 16 the movements of the motor being controlled by a system of magneticallyactuated switches dependent upon the contact or otherwise of the weigh beam with two electric contacts arranged near one end of the beam.

Title: Improvements in or relating to processes for the manufacture of oil gas
Inventor: HARTLEY WILFRED
IPC: B01J8/02
Filed: 1953-08-25
Abstract: 744,201. Oil gas. HUMPHREYS & GLASGOW, Ltd. July 13, 1954 [Aug. 25, 1953; Oct. 12, 1953], Nos. 23475/53 and 28080/53. Class 55 (2). In oil gas generation in which oil and gaseous reactant are contacted with a bed 13 of hot refractory or catalytic material, the gas, generally steam, is passed through a port 14 into the gas making chamber 10 and the oil is projected as a cone of fine droplets co-axial with the port which has a cross-section conforming with that of the cone; the point at which the cone occupies a maximum proportion of the port area, namely at least two-thirds, is at or near its opening into the chamber and the average droplet size is such that continued movement of most of them beyond the port is due solely to gravity and entrainment in the steam. A steam inlet 17 lies on a line passing clear of the axis of a circular entry chamber 15 .to give a slight swirl to the steam which is preheated, e.g. to 1100‹ F. Ports spaced from the axis may be used with the axial ports or large chambers may have a number of ports spaced away from its axis and the swirl imparted to the steam in each port is such that the emerging streams assist one another in rotation.

Title: Apparatus for inducing sleep
IPC: F21V23/00
Filed: 1946-08-08
Abstract: 652,860. Control systems for incandescent lamps. TRASK, A. Aug. 8, 1946, No. 23522. [Class 38 (iv)] [Also in Group VI] Switching and resistance control.-A circuit including a lamp is controlled to produce the effect of twilight or progressively dim the lamp to darkness to induce sleep and comprises mains 31, 32, an automatic switch comprising a motor 30 to rotate the arm 33 of a rheostat 34, a manually-operated switch 23, an adjustable resistance 35 and a lamp 38. In the position shown, of the arm 33 with the switch 23 open, the closing of the switch to connect contacts 24, 25 causes the lamp 38 to be lit and the motor 30 to rotate the arm 33 anti-clockwise until it arrives on the contact 39 which is insulated from the remainder of the rheostat 34 when both the motor stops and the lamp is extinguished. To light the lamp the switch 23 is thrown over to connect the contacts 25, 26 and the contacts 27, 28 when the motor 30 will drive the arm 33 until it leaves the contact 39 and the motor then stops but the lamp will remain alight. The time or speed of dimming may be varied by an adjustment of the resistance 35, or, in modifications, by placing the adjustable resistance in the motor circuit to vary the speed of the motor, or, if no adjustable resistance is used, by using lamps of various wattage.

Title: Bowl-type refractors
IPC: F21V5/00
Filed: 1948-09-07
Abstract: 657,779. Bowl refractors. HOLOPHANE, Ltd., and ENGLISH, S. Sept. 7, 1948, No. 23525. [Class 75(ii)] In a refractor for street lighting of the type in which a compact light source is enclosed within a relatively deep bowl provided with prisms for concentrating the light in radial planes and in which the skirt portion of the bowl extends substantially above the light source, the outside of the bowl is free from prisms on its lower part but its upper part has horizontal prisms redirecting high elevation light to remote areas and the inside of the bowl bears prisms at least in its lower part. The bowl shown in Fig. 1 has a skirt 12 which is either smooth or fluted inside but has annular prisms 14 on its outside for bending downwardly rays from a compact source at a point 10 above the level of the lowest prism 14. The depths of the prisms 14 decrease and their apex angles increase downwardly. The lower spherical part of the bowl is smooth outside but on its inside it has horizontal circular prisms, the depths of which increase and the apex angles of which decrease downwardly so that the rays are concentrated in radial planes to form a fan-shaped annular beam 19-19. The bowl shown in Figs. 2, 4 provides asymmetrical lighting in the form of two beams 21a at 160 degrees to one another. The outsideof the skirt 12 has prisms 14 as in Fig 1 and the inside of the lower portion 11 has two sets of semi-circular prisms 21 centred at a point 22 below the light source, these prisms being adapted to concentrate the light in both radial and horizontal planes. The prisms 21 are continued upwards to merge tangentially into vertical prisms 23 on the inside of the skirt and in order to allow the moulding tool to be withdrawn in the process of making the bowl the prisms 21 are sloped at a small angle to the bowl axis. More than two sets of prisms 21 at any desired angular relationship may be provided in one bowl and the beams from the skirt are arranged to be coaxial with but narrower than both horizontally and vertically, the beams from the prism sets 21. In a modification, Fig. 7, providing two light beams, the lower part 11<SP>1</SP> of the bowl is in the form of a pyramid with straight parallel prisms formed on the inside of the pyramid panels. The inclination of the prisms varies progressively as shown, the panel at the centre of each light beam having horizontal prisms. The conical skirt 12' has internal vertical prisms 33 deviating the light towards the main beams and external annular prisms 14<SP>1</SP> bending the light downwardly. The lower horizontal panel 35 may have diffusing prisms. Prisms of the form shown in Fig. 5 having curved active faces 16a separated by flats 24 may be used. Specifications 351.761 and 617,927 are referred to. Specification 217,539 also is referred to in the Provisional Specification.

Title: Improvements in or relating to electromagnetically operated vibrators
IPC: G01S1/72
Filed: 1919-09-25
Abstract: 148,703. Jackson, W. J. Mellersh-, (Submarine Signal Co.). Sept. 25, 1919. Subaqueous audible signals.-An electro-magnetic vibrator, especially adapted for use in submarine signalling, produces compressional waves in a liquid by a method which consists in vibrating a vibratory member in contact with the liquid by establishing a series of magnetic fields and bringing them in turn into influencing relation to a non-magnetic member connected to the vibratory member so as to cause the non-magnetic member to be intermittently attracted and released, thereby putting the vibratory member under stress and release. As shown, the vibrator comprises a non-magnetic cylindrical conductor D, Figs. 2, 5, and 6, placed in the air gap between two outer and two inner sets of electromagnets E<2>, E<3>, and attached by a strap J to a diaphragm K which may be placed in the side of a ship L. The electro-magnets are fixed to the shaft A<2> driven by an electric motor, the rotating magnetic fields on completion of the electric circuit exerting a varying pull on the conductor D against the resistance of the diaphragm R, thereby setting up in the diaphragm vibrations corresponding to the speed of the motor. By varying the speed of the motor, signals differing in pitch may be sent out to different ships tuned to receive the signals. The conductor D comprises two narrow end bands d<10> and a central band d<1> connected by transverse strips d<2>, the spaces d<3> having a larger area than that of the strips or the magnet faces. Another form of conductor is shown in Fig. 13, consisting of bars R connected as shown to form a continuous circuit in which is inserted a battery operating a circuit closer of similar form to that shown at M, Fig. 2. Instead of a diaphragm, a reed N, Fig. 8, may be attached to frames P in the side of the ship so that the vibrations may be given to the frames and transmitted to the ship's side. The electric circuit, which includes the relay M, is shown in Fig. 2, the lower coils of the magnets being shown in elevation. The coils are so wound and connected that north and south poles will alternate around the machine and the north poles of the outer set of electro-magnets will be opposite the south poles of the inner set and vice versa. Part of the skin of the ship or a tuning fork or the like may also be used as a vibrator.

Abstract: 691,206. Load handling machines. AITKEN, J., [trading as AITKEN & ALLAN]. Oct. 1, 1951. [Sept. 30, 1950] No. 23982/50. Classes 78 (i), 78 (ii), 78 (iii) and 78 (iv). Turntable apparatus A having side tracks 11 is pivoted at 7 and rotatable about a vertical axis. The piatform has rollers 13 and 14 engaging cam tracks 16 and 17. The platform has a pair of stops 12 with weights 23 mounted on a shaft 22, and held in position by a member 18 pivoted to a bracket 24 on the turntable engaging a cam 25 on the shaft 22. The platform tips under load and rotates until the member 18 contacts a fixed side stop 20 which moves the cam 25 to disengage the stops 12 which move to allow the discharge. The turntable is returned to the horizontal by a counterweight 21 and member 18 re-engages the cam 25. Rotation of the turntable can be prevented by a lever 26 pivoted on shafts 27 and connected to a lever 30. The lever 26 passes between two spaced members 29 which are out of alignment so that when the lever is central the turntable cannot rotate, and to discharge it is necessary to rock the lever by hand. When the lever 26 is moved angularly by the lever 30 the turntable is freed to rotate in one direction only. In a modification for boxes the turntable has rollers, one cam track is horizontal, the other curved. To prevent rotation of the turntable a member on the hollow cylinder 15 locks the roller 14. The turntable can tilt without rotation.
