Title: Improvements in and relating to apparatus for conveying materials
IPC: B65G17/12
Filed: 1949-06-15
Abstract: 672,220. Endless conveyers. BIRTLEY CO., Ltd., and HOLMES, C. W. H. June 15, 1950. [June 15, 1949] No. 15896/49. Class 78 (i). In a conveyer consisting of two portions pivotally connected, each portion consisting of an upper and a lower set of guide rails upon which run rollers mounted on transverse spindles and interconnected by an endless chain or chains, profiled plates depend from the chains at each side and a continuous belt is associated with the plates and spindles in such a way that a pocket is formed between successive pairs of rollers. The two portions 1, 3, Fig. 1, pivotally connected at 9. comprise guide rails 25, 27, 29, 31 on which run the rollers 23 interconnected by endless chains 21, which are passed over end sprockets 13, 19, one of which is driven by a motor 15, Fig. 6. Portion 3 is mounted on a carriage in an elevated position to travel under a hopper, Fig. 6. Coal from the hopper is fed to the pockets of the conveyer on portion 3 and passes via portion 1, which is suitably adjusted, into a vehicle or hold of a ship. The pockets are formed by an endless belt 47 which is threaded over the spindles 33 on which rollers 23 are mounted, and under profiled plates 37 fixed to the endless chains at each side between the spindles 33. The plates 37 are cranked, Fig. 4 so that they lie within the edges of the belt 47 and are provided with a flange 45 extending around the bottom and sides. The belt 47 is secured to this flange by means of a bent strip 45<SP>1</SP> and bolts 49. Some slack is left between adjacent plates 37 so that, owing to the stiffness of the belt, the belt lies clear of the spindles 33. The leading edges of the plates 37 are vertical while the trailing edges are about 45 degrees to the horizontal when conveying horizontally so that when conveying downwardly, Fig. 6, material does not spill out of the pockets thus formed.

Title: Improvements in diving apparatus
IPC: B63C11/44
Filed: 1927-06-21
Abstract: 294,749. Davis, R. H. June 21, 1927. Diving-chambers; divers' dress.-A diver's chamber consists of a closed vessel a, Fig. 3 with a door, or two juxtaposed doors, through which the diver enters. It is then lowered to the sea bottom, air being supplied by a pipe c. If then the diver desires to leave the chamber. he connects his helmet to the air-supply pipes f. h and opens the door or doors. He may later reenter, close the doors, allow the water to be forced out through a valve l by the air from the pipe c ; the chamber then may be lifted to the surface, and after a period of decompression regulated by an air escape valve, the diver may leave it. Lamps n, windows r, an air-escape valve m, gauges p, and telephonic apparatus o x are fitted, and the chamber may also be supplied with cylinders i, j for suitable compressed gases, e.g., air or oxygen, or oxygen-helium and other mixtures. To enable a diver who has descended in the ordinary way to enter this chamber, his dress is fitted with a three-way valve s, Fig. 5, to enable his helmet to be supplied with air either by his direct air pipe u, or, when that has been disconnected and he has entered the chamber, by the pipes f, h, Fig. 3. If the diver is wearing self-contained diving- apparatus, it will only be necessary to disconnect the telephone connection y before leaving the chamber. A similar or larger decompression chamber may be fitted on the deck of a ship, and the chamber a may be connected to it or placed on it; the diver may then leave the chamber a for the decompression chamber, and thus enable the chamber a to be used by another diver.

Title: Improvements relating to electrical sawtooth waveform generators
Inventor: HALL ANTHONY
IPC: H03K4/22
Filed: 1954-06-08
Abstract: 767,606. Saw-tooth generating circuits. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 23, 1955 [June 8, 1954], No. 16831/54. Class 40(6) In a miller transitron saw tooth generator of the type in which the miller capacitance is coupled between anode and grid through a cathode follower, the transitron coupling between screen and suppressor grids is of the direct current type and a variable point in the cathode circuit of the cathode follower is connected to the screen and suppressor grids so that part of the positive going fly back voltage wave may retrigger the sweep when the anode potential reaches a predetermined level. In the circuit shown the miller capacitance discharges linearly until the anode potential of the valve V2 bottoms. The current is then diverted to the screen grid thus lowering the screen grid potential. The coupling through'R4 causes the suppressor potential to decrease correspondingly, hastening the lowering of the screen grid potential and this continues until the anode current is cut off. This causes the anode' potential to rise and when the corresponding potential at the tapping on cathode follower resistance' R8 has risen sufficiently the diode V3 conducts and supplies a positive going voltage to the screen and suppressor grids and initiating the next sweep. As the tapping of potentiometer R8 is moved towards the earthy end the repetition frequency of the output wave is decreased and the amplitude increased until a point is reached at which the circuit is no longer free running. Synchronizing or triggering voltages may be applied to the screen and suppressor grid through a diode V1.

Abstract: 953,444. Oxygen lances; supplying powder to furnaces. BRITISH OXYGEN CO. Ltd. May 4, 1961 [May 12, 1960], No. 16860/60. Heading F4B. A handle for an oxygen lance, Fig. 1, comprises a cylindrical outer wall 10 with a valve block 11 and a nose block 12 at its ends supporting a central oxygen conduit 13. The valve block 11 has an oxygen inlet connection 14 and a normally closed oxygen supply valve opened by the lever 16. The nose block 12 is screwthreaded at 18 to receive a lance of one diameter and counter-bored with a thread 22 to receive a lance of a larger diameter, an extension part, or a chuck, Fig. 3, which has a nut 28 by which a resilient ring 30 can be tightened to grip the plain end of a small diameter lance. The extension part, Fig. 2, has passages 36, 38, 37, 39 for oxygen from the handle part, a connection 41 for a powder supply, and a powder nozzle 47 which protrudes into a lance held in the screwthreaded oxygen outlet 40. The powder inlet connector 41 engages a block 44 with a conduit 45 connected to the powder nozzle 47 by a flexible sleeve 48 and an end block 46. The supply of powder can be controlled by a pinchcock comprising a stirrup 49, and a cam lever 50 so that the sleeve 49 is squeezed against the underside of the oxygen conduit 37 when the lever 50 is raised. In another embodiment, Fig. 6, the extension part has an oxygen passage 56, 57, 58, and a powder conduit 61, 62 leading to the powder nozzle 63. A sleeve 68 carrying a pinch-cock valve comprising a ball 69 and an actuating screw 70 connects the flexible powder supply tube 66 to the powder inlet 59 of the extension part body. Since blow-back usually extends only to the point at which powder enters the oxygen stream, an operator is less liable to injury, since the handle part has no powder connections.
