Title: Improvements in and relating to remote control apparatus for operating valves
IPC: F16K31/06
Filed: 1935-01-25
Abstract: 439,602. Valves. WERKSPOOR NAAMLOOZE VENNOOTSCHAP, 62, Oostenburgermiddenstraat, Amsterdam. Jan. 25, 1935, No. 2560. Convention date, Jan. 30, 1934. [Class 135] Mechanism for remote control of a valve 5 and of the type in which a valve-actuating rod is in two parts 6, 8 coupled together by a device by means of which the valve can be closed from a distance, is so arranged that the valve can be returned either to the open or the closed position by means of the distant control. The stem 10 of a member 9 rotatably attached to the rod 6 extends into an enlargement 12 of the rod 8. Balls 20 are seated in conical holes 19 in the enlargement 12, and normally are pressed inwardly by an iron core 16 having limited vertical movement on the part 12, so that when the rods 6, 8 are moved towards one another the balls 20 drop into a groove 21 in the rod 6 and are held therein by the core 16, the rods 6, 8 thus being coupled together. The rod 8 has screwed engagement with a bridge part 3 so that rotation thereof by a hand-wheel 7 causes actuation of the valve 5 when the rods 6, 8 are coupled together. To release the coupling and allow the valve 5 to close under the action of gravity and a spring 24, the core 16 can be lifted either by a rod 27 connected by a wire 29 to a remote manual-control or by closing a distant switch actuating an electromagnet 14 surrounding the core 12 and mounted on a plate 13. To provide for opening the valve, a rod 25 is attached to the rod 6 and extends through and beyond the rod 8. At its extreme end it is attached to the core of an electromagnet which can be operated from a remote control either electrically or by a wire connection similarly to the operation of the core 16. Operation of the rod 25 causes the stem 10 to be lifted so that the balls 20 drop into the recess 21 under the action of the core 16 to hold the valve in its original opened position.

Abstract: 662,777. Endless conveyers. MOTTRAM, W., and JOHNSON (MACHINERY), Ltd., C. H. April 30, 1949. [Feb. 2, 1949] No. 2839/49. Class 78 (i). In a push-plate conveyer wherein conveying, screening and grading of material is effected simultaneously, the trough along which material is conveyed is formed with an aperture or apertures in which is or are located a screen or screens and a further screen is located so as to receive material passing through the said screen or screens, said further screen delivering the material failing to pass therethrough to a hopper or shoot, whilst material passing through said further screen falls into a second hopper or shoot, the material too large to pass through the screen or screens in the bottom of the trough being carried along the trough by the conveyer. Fig. 1 shows an embodiment in which coke is conveyed along a trough by push plates 12 secured to a pair of endless chains 11 over a screen 16 having a fine portion 16a and a coarser portion 16b. Coke passing through these screens falls through the return run of the conveyer on to a screen 18 located in a plate 17. Coke passing through this latter screen falls to a hopper 22, whilst larger material such as coke nuts falls into a shoot 24 for bagging. Coke too large to fall through the screen 16b is carried up the trough 15 for delivery to a vehicle or other receiving device. Guide bars 25 fitted to the sides of the trough serve to keep the push plates in sliding contact with the screen 16. The device may function solely as a conveyer by masking the screens 16 by slidably mounted plates 19. The coke is fed to the conveyer by means of hoppers 26, 27, the former being adapted for direct filling manually and indirect filling from the hopper 27 which is filled from a dumper or by mechanical means.

Title: Pulse communication system
IPC: H01S5/062
Filed: 1965-01-22
Abstract: 1,062,951. Photo-electric ranging. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 22, 1965 [March 11, 1964], No. 2852/65. Heading H4D. [Also in Divisions G1 and H1] A ranging system utilizes a semi-conductor laser device. In a particular application to determine both range and rate of closure of space craft, the system is mounted aboard a capsule 9 and comprises a source 3 of driving pulses of current, providing a train of pulses of a set duration and amplitude, which are applied to a modulator 4. This provides amplitude modulation of the pulses applied to the laser 2, a resultant light pulse being subject to a delay between the application of an input pulse and its commencement, inversely proportional to the amplitude of the input pulse. This factor enables the production of very narrow light pulses, advantageous in high-resolution techniques. Amplitude modulation of pulses enables easy location of a target (using a large pulse) followed by high resolution measurement. Light pulses are transmitted in a highly concentrated beam provided by parabolic reflector and lens system 12, and bounced off the reflector 11 of a canister 10, being received by a PN junction detector 7 the output of which is passed to a display device 8. A communication link may also be provided, as the system has particular application in this field (see Division G1). Details of the laser device and its operation are given and a theoretical explanation of the delay mechanism. Other applications include small distance measurement and calibration of optical devices.

Abstract: 128,520. Wright, D. M. June 5, 1918. Guards, controlling.-In die presses and the like, particularly such as are described in Specification 125,808, a guard surrounding the dies controls the driving - clutch through a detent co-operating with a clutch - disengaging cam-lever. The guard 35 is moved downward to cover the dies 27, 28 and carries a pin 3'7 engaging a plunger 39 on a rod 41 normally held raised by a spring 40. The rod 41 is linked to a lever 57 whose arm 58 normally engages a lug 59 on the side of a camlever 48 spring-pressed to engage with and withdraw a sliding clutch pin 46 carried by a dieactuating collar 47. To throw the clutch into operation for one revolution, a pedal 54 is lowered and swings a lever 50 linked to a latch 44, which engages a lug 49 on the lever 48 so that the arm 48 is lowered and the clutch pin 46 released. A projecting pin on the driving-pulley during its rotation then strikes the pin 46 and starts the machine, the pin 46 during its rotation striking the latch 44 and disengaging it from the lever 48 which returns to position to disengage the clutch at the end of the revolution. A hand-lever 42 is connected by pin and slot means to the lever 48 so that the lever may be kept lowered and the clutch permanently engaged. When the cage 35 is in its raised position, the arm 58 prevents movement of the lever 48 and so engagement of the clutch.
Patent GB-472738-A (GB)
Title: Improvements in or relating to the manufacture and use of plastic masses, paints, lacquers, coatings and the like composed of aqueous dispersions of linoxyn
IPC: C09K23/00
Filed: 1937-02-01
Abstract: An aqueous dispersion of linoxyn in the form of a plastic mass, paint, lacquer, coating or lining material or like composition, contains material which, while being chemically inert to the linoxyn, renders the dispersion heatsensitive in the sense that it is stable against coagulation at normal temperatures but unstable, with resulting mass-coagulation of the dispersion, at a raised temperature.  The heat-sensitizing material may be added as such, or may comprise substances which react in the dispersion to produce the active coagulant in situ, and two or more separate sensitizing materials may be employed together in the same dispersion.  Specified heat-sensitizing materials are salts of alkaline earth metals, oxides of zinc and magnesium, and mixtures of a protective colloid such as casein, haemoglobin and albumen with a salifying agent therefor, such as soluble salts of magnesium, calcium and zinc.  Solid products may be made wholly or in part from the dispersions.  For instance, floorings may be made by spreading the dispersion on a prepared undersurface and then causing mass-solidification of the dispersion by traversing over it a heated iron or roller, while dipped goods may be made by dipping a surface into the dispersion and locally heating the dispersion from the said surface.  According to examples: (1) a mixture of linoxyn and an ammoniacal solution of casein is kneaded with ammonia solution, and, to the dispersion so obtained, is added about 2 per cent of a soluble salt of magnesium.  Pigments, fillers, bitumen, fibrous materials, &c. may be added.  The resulting dispersion may be employed for waterproofing paper by applying the dispersion thereto and then applying heat; (2) a heat-sensitive aqueous dispersion contains linoxyn, water, ammonia, haemoglobin and zinc sulphate.
