Title: Improvements in artificial arms
Inventor: STEEPER CHARLES PHILIP
IPC: A61F2/58
Filed: 1952-06-12
Abstract: 738,980. Artificial arms. STEEPER (ROEHAMPTON), Ltd., H. June 9, 1953 [June 12, 1952], No. 14823/52. Class 81 (2). In an artificial arm assembly of the kind in which the hand may be rotated relatively to the arm there is provided an oval-shaped wrist division, for connection and removal of the hand, and a forearm division of circular shape for rotation of the hand and lower portion of the forearm. As shown the forearm is divided at 1 into portions 2, 3, the upper end of portion 2 being connected by elbow mechanism to the upper arm whilst the lower end of portion 3 is provided with a wrist-plate 6 to which a hand 5 is attachable. The abutting ends of portions 2, 3 are circular in shape whilst the wrist plate 6 and plate 7 of the hand are of oval shape. The bearing for rotatably connecting portions 2, 3 is formed on the one hand by a flange 2A on the lower end of 2 and on the other hand by the end 3A of 3. Abutting against and overlapping the inner surface of 2A is a circular plate 3C which is screwed to the end 3A. Five equally spaced holes 8A are drilled in the flange for selective engagement by a bolt 8 slidably mounted in a tube 9 fixed to a plate 9A itself screwed to the end 3A. The bolt 8 may be retracted against a spring 10 to permit free rotation of 3 relative to 2 or it may engage under spring pressure any one of the holes 8A to thereby lock the portion 3 in a desired position relative to the portion 2. Retraction of the bolt is effected by inward pressure on a curved finger plate 11 which is mounted on a plate 12 slidably mounted with respect to the plate 9A a spring 12 A connecting plates 12 and 9A such that the plate 11 is always spring-loaded outwardly. The plate 12 carries a pawl 13 spring-loaded into engagement with a ratchet wheel 15 rotatably mounted on the tube 9. The wheel carries a number of cam depressions 16, 16A, arranged to engage a pin 17 which is fixed to the bolt 8 and extends at right angles to it and runs in a slot 8B in the tube. When the plate 11 is pushed inwardly alternate movements rotate the wheel 15 so that the pin 17 rides into a depression 16 or 16A, these depressions being alternately deep and shallow such that a shallow depression holds the bolt out of engagement with a hole 8A whilst a deep depression allows the bolt to engage a hole. In the hand and wrist plate connection shown when the piece 18 is inserted in the socket 19 the head 18A deflects a blade catch 20 against a spring 21 and when the piece 18 is pushed home the catch enters the groove 18B and prevents withdrawal of the hand. Interengagement of a bar 19A in the socket with a slot 18B in the head 18A prevents rotation of the hand relative to the portion 3. When the hand is to be removed the catch is retracted from the groove by pressure on a plate 21A which is moved inwardly against the spring 21 causing thereby movement of a half-annular rocker member 20A, of which the blade catch forms an integral part, about a pivot 20B on the socket wall.

Abstract: 734,722. Locks; sliding bolts. PARKES & SONS, Ltd., J., and BUTTER, F. J. May 12, 1954 [May 28, 1953], No. 14846/53. Class 44. In a lock of the kind in which a dead bolt 12 is operated by a lever, the lever is mounted to rock about a fixed axis 23 and has two arms 13, 14 which co-operate respectively with inclined ramps 15, 16 on the bolt to effect full throw of the bolt, one in the bolt-shooting direction and the other in the bolt-withdrawing direction and at the end of the bolt-throwing action whichever arm has effected such action rides off the associated ramp and takes up a dead-centre position, or a position a little beyond dead-centre, in which it operates as a strut between an abutment 17 or 18 on the bolt and the lever pivot to retain the bolt against movement in the opposite direction until again actuated by the lever. As shown, the lever is adapted to be rocked from one side of the door by a handle (not shown) and is provided with an arm 24 by which the lever is rocked from the other side of the door by a thrower 28 carried by a cylinder lock 26. A pin 30 on the arm 24 co-operates with one arm of a spring located on a stump 32 to bias the lever to either of its extreme positions. In another arrangement, Fig. 2 (not shown), the arm 24 is engaged and rocked by an intermediate bellcrank member which is engaged by the thrower 28. In a further arrangement, the thrower 28 engages a slider which is adapted to rock the bolt lever, the runner being indexed in its extreme positions by one arm of a leaf spring mounted in the lock case. The slider may be secured by levers and the levers in the slider may be operated directly by the bit of a key.

Title: Improvements in and relating to fuel-injection systems for internal-combustion engines
IPC: F02M69/50
Filed: 1952-06-13
Abstract: 734,279. Regulating ; rotary distributing valves. USTAV MOTOROVYCH VOZIDEL, BOTTGER, J., and KOPLIK, O. June 13, 1952. No. 14965/52. Class 7(6). In a fuel injection system for multi-cylinder internal combustion engines comprising a fuel pump and a rotating distributer for metering the fuel to be supplied through pressure pipes to the individual injection nozzles of the engine, the substantially cylindrical distributer casing is provided with a central axially extending bore containing a rotating distributer shaft and with a number of discharge ports arranged in each of at least two planes at right angles to the distributers rotary axis which discharge ports are in communication through radially extending channels with the central bore are adapted to be connected to pressure pipes which lead to the engine cylinders and are arranged in the range of only one half of the circumference of the distributer casing, and the control grooves of the distributing shaft which control the fuel supply to the discharge ports in the different planes are angularly displaced with respect to one another. Fuel from a pump (not shown) enters by an inlet port 3 and is distributed to outlet connections 10, 10<SP>1</SP> by means of a rotary distributer shaft 2. The connections 10 10<SP>1</SP> as indicated by Fig. 2 are not evenly distributed around the distributer casing but arranged to extend approximately half way round the casing. This avoids sharp bends in the pipes leading to the injectors and thus helps to give a more even distribution of fuel. The distributer shaft is axially adjustable to vary the quantity of fuel supplied. The shaft has distributer grooves 8,81. In a modification further grooves are provided in the shaft which register with outlet ports after the distributer grooves 8, 8<SP>1</SP> and connect these ports to a discharge passage thus relieving the pressure in the pipes leading to and preventing dribbling of the injectors. The arrangement of the discharge ports at two or more levels in the range of one half of the circumference of the distributer casing with a corresponding displaced arrangement of the control grooves can be applied for instance to distributer constructions which work without means for varying the time of commencement or of termination of the injection interval. A return connection 9 is provided by which surplus fuel may escape through a valve controlled return pipe. The inlet for fuel under pressure into and the return connection or connections 9 for the excess fuel from the distributer may be arranged at that half of the distributer casing which is without discharge ports leading to the injection nozzles. Specification 733,552 is referred to.

Patent GB-717206-A (GB)
Title: Improvements in manufacture of carbon black
IPC: C09C1/50
Filed: 1952-06-16
Abstract: <PICT:0717206/III/1> p  In a process for producing carbon black of the type described in Specification 669,986, the fluid hydrocarbon fuel and free oxygen-containing gas of the combustible mixture are so proportioned as to produce oxidizing blast flame gases and gaseous or vaporous oxygen scavenger is introduced into the furnace separately from the combustible mixture and mixed with the oxidizing blast flame gases in proportion sufficient to prevent burning of the hydrocarbon make by the oxidizing constituents of the blast flame gases.  The oxygen scavenger may be flue gas, preferably hot, containing hydrogen, natural gas, or low molecular weight paraffinic hydrocarbons or pure hydrogen.  Natural gas supplied through pipes 12 and air supplied through an inlet pipe and annular duct 14 are mixed in and blasted from one or both sets of four tangentially directed burners 8 into refractory heat-insulated chamber 1.  Liquid hydrocarbon, supplied through pipes 10, is atomized by gas under pressure supplied through pipes 11, through radically directed nozzles 9 into the swirling body of combustion gases in chamber 1. The effluent gas passes to cooler 2 having water sprays 24 and the cooled suspension is withdrawn at 26 for separation.  The oxygen scavenger may be mixed with the combustion gases prior to injection of the hydrocarbon make by passage through pipe 4, or, where only one set of burners 8 are used for producing the combustion gases, by passage, without air, through one or more of the other set of burners 8.  Alternatively, the oxygen scavenger may be used as, or in admixture with, the atomizing gas for the liquid hydrocarbon make. When natural gas is the oxygen scavenger the ratio of air to total fuel gas plus oxygen scavenger may be 6.85 : 1, but is preferably not lower than 9 : 1, and the amount of oxygen scavenger should be such that 85-90 per cent. complete combustion occurs, in which case the air-total gas ratio is usually 9.3-9,8 : 1.  The blast flame gases after addition of the oxygen scavenger may contain 4.5-10 per cent. CO2, 9,5-3 per cent. CO, and less than 1/2 per cent. O2.  The liquid hydrocarbon make may be heavy residuum oils such as No. 5, No. 6, or Bunker C fuel oils, "pressure tar," or "flash drum tar" having AP.1 values +10 to -6, viscosities 125-250 at 122 DEG  F., and specific gravities 0.95-1.1, which are soluble in pentachlorphenol.  The hydrocarbon make may be preheated to 250 DEG  F. but not above 500 DEG  F. Specifications 692,129 and 692,130 are referred to.

Abstract: 109,682. Accles & Pollock, and Barlow, J. R. Oct. 25, 1916. Crank-axle brackets.-Bicycle bottom brackets are made from a single sheet-metal blank a. which is so shaped and bent as to provide the complete lug b for the seat-pillar tube at one end of the blank and the complete lug c for the bottom tube at the other end of the blank. The centre of each end of the blank is first drawn or pressed down to form U-shaped projections, and the middle of the blank is curved up at right-angles to the end projections to provide the barrel of the bracket. The lugs k, m for the chain stays are formed by piercing holes in the blank at the wide portion thereof between the curves d<1>, e<1>, and then forcing or drawing the metal outwardly until the desired size of lugs has been obtained. In the final operation, the projections and barrel portion of the blank are closed up and the meeting edges welded together. To provide projections for cotter-pins upon the barrel, the blank sides may have extersions which are drawn in by the action of drawing up the metal to form the projections.

Abstract: 1424044 Alarm watches CITIZEN WATCH CO Ltd 30 March 1973 [5 April 1972 15 June 1972 (2) 24 Feb 1973] 15352/73 Heading G3T [Also in Division G5] An alarm watch includes a magnetic record/ playback arrangement permitting reproduction of a recorded message at a pre-set time. As shown the recording is made on an annular body 23 but an alternative arrangement is described Figs. 15-19 (not shown) which uses a loop of tape (208). The body 23 is driven by a spring barrel 16 which is coupled to a ratchet wheel 21 and thus wound by operation of a playback button 7 and a record button 6. The drive is via gears 27-31 and the speed is controlled by a magnetic governor 10, 11. To record, button 6 must be depressed after button 7, thus ensuring adequate winding of the barrel for playback also, and bringing an erase head (9), Figs. 3 and 9A, B (not shown) into contact with the body 23. A changeover switch Fig. 10 (not shown) is also actuated in record/playback circuitry 14 so that a loud-speaker (1), Fig. 2 (not shown) in a housing attached to the watch case functions as a microphone. The circuitry is powered by a cell 13 which also drives the watch movement. After one revolution, the magnetic body 23 is stopped, ready for playback, by a lever 43, Fig. 7, dropping into a notch in a plate 41 coupled to the body. Playback is possible at any time by depression of button 7, or the alarm mechanism may be inactivated by pulling out the button. Setting of the alarm time is performed by a stem 5 which is pulled out and rotated to turn an alarm set cannon 19 having lugs 19' relative to an hour cannon 20 with apertures 20'. The stem 5 is then pushed fully inwards to position a trigger lever 51. On initation of the alarm, the playback amplifier is caused to oscillate for a short period to provide an alarm signal from the loud-speaker, followed by the recorded message.
