Title: Improvements in or relating to bogies and axle-trucks on vehicles
IPC: B61F5/14
Filed: 1933-03-14
Abstract: 416,390. Railway-vehicle suspensions. SENTINEL WAGGON WORKS, Ltd., 20, Iddesleigh House, Caxton Street, Westminster, and HUTT, A. C., c /o Sentinel Waggon Works, Shrewsbury. March 14, 1933, No. 7762. [Class 103 (vi).] In order to minimize vertical vibration the body 37 of a railway &c. vehicle is wholly or partly transmitted to the axle-truck or bogie frame by means of pneumatic cushions 29 of rubber or like material, while lateral shocks between the frame and bogie are absorbed by means of an additional cushion 35. In the construction shown the cushions are carried by a transverse member comprising a base 21, transverse vertical walls 19, 20, longitudinal vertical walls 110, 111 and a central troughshaped member 23, 24, the whole being united by plates 22 to the side members 10, 11 of the bogie frame. The cushions 29 are mounted on hubs 30 slidable to a small extent against the action of springs 33 on pins 27 secured to the members 10, 11, 110, 111 and to the walls 24 of the central member 23. The cushion 35 is spring-mounted on a king-pin 26 secured to the base of the member 23 and co-operates with a cylinder 36 fixed to the vehicle body 37. To prevent tilting of the body due to the deflation of the cushions on one side, rollers 40 on the under side of the body are adapted to co-operate with upper and lower tracks 42, 44 on the bogie. For inflating the cushions 29 at one or other side of the bogie, a common bore may be formed in the hub 30, and the pins 27, 28 may in this case be dispensed with. In a modification the king-pin 26 is secured to the vehicle body, and the cushion 35 mounted thereon co-operates with the trough member 23.

Title: Steering rudders for river and ocean going vessels
IPC: B63H25/38
Filed: 1926-03-22
Abstract: 259,831. Eckes, C. March 22, 1926. Rudders. - The whole or part of a balanced rudder is hung to swing fore and aft on a horizontal transverse pivot whereby on going ahead or astern the rudder takes up automatically a balanced position. On the rudder spindle 2 is a transverse spindle 3 on which is hung the rear third 6 of the rudder and the forward two-thirds 1, the former being also supported at 4 on the frame, and the latter by a roller in a bottom groove. When going astern the portion 1 swings forwardly behind the spindle axis so that the rudder is again balanced. In a modification the whole of the rudder is in one piece and swings on the pivot, and an after stiffening frame may be fitted. In addition to dynamic balance, the static balance may be obtained by the provision of counterweights. Instead of pivoting the blade it may be arranged to slide to and fro on rollers.

Title: Apparatus for Charging Pressurized Spray Containers
Inventor: SIEBEL CARL GISBERT
IPC: B65B31/00
Filed: 1969-02-13
Abstract: 1,189,962. Filling pressurized spray containers. C. G. SIEBEL. 13 Feb., 1969 [13 Feb., 1968], No. 7889/69. Heading B8T. [Also in Division Fl] A pressurized spray container 28 is charged either with a liquid or a gaseous propellent, from sources 7 and 8 respectively, by means of a pneumatic piston 3 and cylinder 1, an extension or hollow rod 6 of the piston being lubricated from an annular chamber 14, the charging material entering a tempered chamber 19 before being expelled through a detachable filling head 9 surrounded by a jacket 31 for cooling liquid. Sealing rings 17 and 18 are of chemically resistant material. Filling liquefied propellent.-Liquefied propellent gas is delivered, by means of a pump 49, from the source 7, through a three-way valve 44 and a valve 43 and into the charging chamber 19. The pressure on the liquid is increased by charging the driving cylinder 1 until it exceeds the closing force of a piston 23 in the filler head 9, whereupon the latter separates itself from a gasket 25 and liquefied propellent gas flows into the pressurized spray container 28. Filling gaseous propellent.-Gaseous propellent is delivered from source 8, reduced to the required pressure by a valve 47, brought to the required temperature by passing through a coil 46 in a container 32 for tempering liquid, passed through valves 44 and 43 and into the charging chamber 19. The gas is then compressed and discharged into the pressurized spray container 28 as in the case of a liquid. In this case, unlike with the liquid, compression releases thermal energy but part of the heat may be conducted away by liquid in the tempering jacket 30.

Title: Improvements in electric door-operating devices
IPC: B66B13/08
Filed: 1929-03-11
Abstract: 330,588. Elevator Supplies Co., Inc., and Shonnard, H. W. March 11, 1929. Operating doors and gates electrically and by springs.-Lift cage doors and the doors on the floor at which the lift cage has stopped are operated by an electric motor through a toggle linkage, the toggle having a spring connected thereto in such a manner as to operate to press the toggle to continue the opening or closing movement of the doors after the motor has effected the partial opening or closing movement. The cage gate 10, Fig. 1, is a collapsing gate, the doors at each floor being of two or more slidable sections 18, 19 operable through links 20 - - 23 connected at one end to a wall bracket 24, these links acting as a toggle lock when in the aligned position The lift cage carries an electric motor 13, preferably of the threephase alternating current type, the motor being geared with a toothed disc 14 the shaft of which is connected to a rockable member 11 through a crank 15 and link 16. The opposite end of the crank 15 is connected by a link 17 with a reversing switch A of the motor. The member 11 is connected through an arm 12 with a forked member 34 which, when the gate is stopped, at a floor, is positioned to engage a plate member 32, as shown in Fig. 3, to make operative engagement between the collapsable gate and door members 10 and 18. In this position and the motor being energized, the lever 11 is rocked and the arm 12 moved to cause the gate to begin its opening movement. At the same time the forked member 34 moves the plate 32 to the left, Fig. 1, and a pin 31 on a slidable bar 28 secured to the plate member is forced against a thrust plate 33 secured to the toggle arm 20. By this means the toggle lock of the door sections 18, 19 is broken, the parts moving towards the position shown in Fig. 7 by the continued action of the motor. When the door is about half open the spring 25 at the wall-end of the toggle links has been moved from the position shown in Fig. 1 into a position in which it is able to exert an expansive force to continue the opening movement of the door and gate, as shown in Fig. 7; in this operative position of the spring the switch A is reversed to cut out the motor. The spring 25 may be positioned as shown in Fig. 9. In this modification the spring is carried by a rod 98 pivotally mounted at 99 and operatively connected at 101 with the pinion 95. When the motor is in operation the spring is compressed between the parts 99, 100 until the rod 98 is swung across the centre of the pinion 95, the motor being cut off as the spring operates to complete the opening or closing movement of left door and gate. The circuit arrangements for the motor include a relay that is energized only when the lift-cage is running, in order that the motor is energized to exert a relatively wealc torque to act continually in a direction to hold the gate in the closed position.

Title: New pyrimidine compounds
Filed: 1943-09-29
Abstract: 2 - Arylguanidino - 4 - halogenpyrimidines, wherein either or both of the 5- and 6-positions may be unsubstituted or may be occupied by a hydrocarbon radical or the 5- and 6-positions may be joined by an aliphatic hydrocarbon radical to form an alicyclic ring, and wherein the aryl radical of the 2-arylguanidino group may be unsubstituted or substituted by one or more non-acidic substituents, are made by reacting an appropriate 2-arylguanidine-4-hydroxypyrimidine with the pentachloride, pentabromide, oxychloride or oxybromide of phosphorus or with a mixture of such agents.  Reaction is effected by heating the reagents together, optionally in the presence of a solvent, e.g. monochlorobenzene, or a diluent, e.g. excess of phosphorus oxychloride.  In general, the substituents on the aryl group may be hydrocarbon radicals (which themselves may bear substituents and which may be attached to the aryl radical directly or through an oxygen, nitrogen or sulphur atom or sulphonyl or carbonyl group), halogen atoms or cyano, nitro, amino, acylamino or esterified carboxyl groups.  In the examples, 2-aryl-guanidino-4-chloro-6-methylpyrimidines are prepared using phosphorus oxychloride.  Specification 581,334, 581,345 and 581,346 are referred to.

Filed: 1949-03-23
Abstract: 682,952. Liquid-fuel burners. BRISTOL AEROPLANE CO., Ltd. March 16, 1950 [March 23, 1949], No. 7979/49. Classes 75(i) and 75(iii) [Also in Groups XXVI and XXXIII] Air is tapped off from the compressor 6 of a gas turbine engine and supplied to a braking thrust producer 12 which comprises a combustion chamber 13 having a burner 14 supplied with fuel by an electrically driven pump 15. The fuel supplied to the burner 14 is ignited by a torch igniter 19 comprising an igniter plug 20 and a fuel jet controlled by a solenoid operated valve 22. The air supply through the duct 24 is controlled by a valve 25 operated by a lever 26. Movement of the lever 26 opens the valve 25 and at the same time completes the circuits of the fuel pump motor 16, ignition coil 21 and solenoid 23 so that valve 22 is opened and the fuel issuing from the jet ignited, which in turn ignites the fuel from the burner 14. The contact strips 28 associated with the coil 21 and solenoid 23 are shorter than that associated with the motor 16 so that the igniter 19 is only used for starting. The fuel pump 15 may be driven by the engine and may draw fuel from the engine fuel supply tank.

Title: An improved machine for binding wire round packing cases or other packages
IPC: B65B13/28
Filed: 1936-03-18
Abstract: 456,563. Wiring packages. CHAMBERLAIN, C. H., and STANNARD, C. P., (trading as CHAMBERLAIN & STANNARD), Victoria Avenue, Nelson, New Zealand. March 18, 1936, No. 8085. Convention date, April 5, 1935. [Class 45] A machine for tying wire around packages comprises a pair of levers 38 pivoted at 37 on a base-plate 10 and provided with wire grips 43, 44 at one end, the other end of each lever being coupled to threaded collars 40 on a right-andleft-hand threaded screw 36 driven through gearing by a hand lever 22. The pinion 35 on the screw 36 is driven by a gear-wheel 20, which may be a segmental gear, and which has a keyway wider than the driving key on the shaft 18 actuated by the hand lever, so that a certain amount of lost motion is provided between the hand lever and the tensioning mechanism. The gear 20 has a recess in its side face, into which a spring-pressed ball 32 may snap, so that on reverse movement of the hand lever, after tensioning, the wire is held tensioned during the initial stage of this reverse movement. The hand lever has spring-pressed ratchet pawls 25 adapted to engage with ratchet teeth on the side faces of a wheel 19 which is in gear with a slotted twisting pinion. A spring-pressed ball 28 snaps into recesses in the face of the gear 19, to hold the twisting pinion in a position where the slots therein permit the insertion and removal of the wires. Thus, no movement of the twisting pinion takes place while the lever 22 is moved to effect tensioning, but on reverse movement of the lever the wires are twisted through a few turns, after which the tensioning arms are restored to initial position and the twisting completed. The final return movement of the hand lever causes cutters 45, mounted on the lever, to sever the surplus wire of the tie.

Abstract: 1,123,743. Electrostatic precipitators. SVENSKA CARBON BLACK AB. 24 Feb., 1966 [15 March, 1965; 16 June, 1965], No. 8150/66. Heading B2J. In an electrostatic precipitator for separating a mixture of gas and carbon black particles and comprising a main container 16 for electrodes 25 with an inlet pipe 15 for the mixture, an outlet pipe 17 for the particle-free gas and an outlet 42 for the separated carbon black particles, a portion of the particle-free gas is supplied by a fan 23 into an insulator chamber 21 above an opening 36 in the roof 31 of the container 16 through which a conductor 29 connected to the electrodes 25 passes, the pressure of the particle-free gas supplied to the chamber 21 being above the pressure in the container so as to prevent the passage of carbon black particles from the container into the insulator chamber. The conductor 29 is supported by a bushing 27 of insulating material which rests on a plate 30 on top of a cylinder 24 of insulating material, e.g. porcelain. Nozzles 33 in holes 32 in the plate 30 direct the particle-free gas tangentially and obliquely on to the inner surface of the cylinder 24. A filter 20 is provided after the fan 23 to remove the last traces of carbon black particles. The particle-free gas may also be treated for the removal of moisture, e.g. by means of a drying agent or by cooling. The mixture may pass through a cyclone 22 before entering the container 16. In order that any flame arc, which may be formed between the roof 31 and the conductor 29, may quickly be extinguished, the roof has a downwardly divergent metal collar 37. Alternatively, a collar 38 is secured to the roof and an upwardly divergent collar 39 downwardly shaped as a casing 40 is secured to the conductor 29, both collars being of insulating material. Other collar and casing arrangements are described and illustrated.

Limbs, artificial.-A plastic hand comprises a foundation to which are rigidly bound flexible fingers comprising stout tenacous pliant cores having a fabric wrapping. A bundle of braided picture wires is tied together and an envelope of several thicknesses of felt or like material 5, Fig. 5, is sewn around it. Lateral stiffening wires 7 preferably of solid formation are sewn thereon and are connected at the outer end by nail loops 9. Tape 10 is then wound spirally around to the required shape and is stitched in position. The felt envelope 5 may be omitted if desired. The device is twice the length of the digit required, and a further envelope of felt is sewn around the metacarpal portion. A foundation member 17, Fig. 12, preferably of aluminium, is covered with felt which is stitched in position and is thicker at the sides than elsewhere. The member 17 is connected to an arm by an internally-screwed portion 18 and may also be provided with an eye 21, for engagement by a locking device of the kind described in Specification 223,725, [Class 44, Fastenings, Lock &c.]. The felt is further secured by stitching with conspicuously-coloured threads through the holes 22 to help in finding the holes for stitching on the fingers. The fingers are secured in position, the middle two on the top and the others, one on each side, the projecting wires 7 being sewn down very strongly. A thumb, of similar form to the fingers; is constructed in which the two wrappings only envelope the digit portion, and the rear portion of the core is fanned out and sewed into an envelope 16<a>, Fig. 11. The thumb 15<a> is sewn in position and coverings of felt 27, 28 are then stitched on. A heavy tape binding 29 is then wound on to form a wrist portion and is stitched in position, a rib 23, Fig. 12, forming an abutment for it. A tape binding 33 and a thumb stay-strap 34 having been stitched on, the hand is covered by a glove 35, Fig. 20, one or more fingers of which carry an adjustable tape 37 for holding it in crooked position. Hooks 36 are attached for aiding in strapping fingers together by elastic bands for holding table implements or the like. A separate thumb 15<a>, Fig. 21, for use alone is slipped into the thumb of a glove 42 or the like worn on or strapped to the hand and may be further positioned by a rubber band 43. Pens or the like may be wrapped with rubber bands to facilitate holding by the artificial thumb.
