Title: Improvements in engine indicators
IPC: G01L23/18
Filed: 1927-03-14
Abstract: 294,126. Hirst, JÀ J., and Goodwin, J. H. March 14, 1927. Steam-engine and like indicators.-An indicator particularly for use with internal-combustion engines for measuring the pressure in the several cylinders at any point in the working stroke comprises a potentiometer wound on the usual paper barrel, an arm with a contact operated by the indicator piston, a voltmeter and current indicator in circuit with the potentiometer and with a balancing potentiometer adapted to be adjusted so that the voltmeter indicates the pressure when the ammeter pointer is at zero. The electric circuit may be completed at any point in the stroke by angularly adjusting a commutator type of contact the rotating brush of which is driven by the engine. The indicator as shown in Fig. 2, comprises a cylinder 1 the piston rod i<2> of which is connected by a link i<3> to a lever S pivoted at s<1> to the arm of a sleeve s<3>. The sleeve has a spring controlled arm s<4> adapted to press a stylus or contact s<5> on the lever S on to the wire R spirally wound on a drum r<5> adjusted, as to its height, by a screw r<6> on the bracket i<4>, the ends of the wire being connected to terminals r<7>, r<8>. A hand operated cock or a piston valve may be mounted on the cylinder 1. An automatically actuated piston valve i<5> is shown in Fig. 2, the piston being attached to the core m<5> of a solenoid M the windings of which are connected to terminals m<7>, m<8>. A passage way i<6> in the piston is adapted to co-operate with ports i<7>, i<8> and a pin i<11> on the piston rod works in slots i<12> in a frame i<13> to prevent rotation of the piston. The electric circuits for a four cylinder engine are shown in Fig. 1, the indicator resistances, contacts and solenoids R<1>, S', and M<1>, &c. are connected to the contacts k<2> of doublepole switches K<1>, &c. on the switchboard and to the lead 2 of the battery E. The other contacts k<1> of the pole switches are connected to contacts B<1> &c. angularly adjustable about a spindle c<2> on which the rotating contact c' is mounted, the spindle being driven, in a twostroke cycle engine, so as to rotate at the same speed as the engine shaft, or in a four-stroke cycle at the same speed as the cam shaft. On the switchboard is mounted a voltmeter V<1>, an ammeter V<2> and a potentiometer P. The ends of the potentiometer are connected to the battery E by leads 3, 4, and a main switch D. The movable contact p<3> of the potentiometer is connected to one side of each instrument. The other side of the instruments is connected to the common leads 7, 8 of the pole switches, the lead 8 being branched at 9 and connected to the end p<2> of the potentiometer. In operation, when the appropriate switch K<1> &c. has been set and the commutator contacts B<1> &c. adjusted, movement of the potentiometer contact p<3> to bring the reading of the ammeter V<2> back to the central zero causes the voltmeter V 1 to indicate the pressure.

Filed: 1925-03-16
Abstract: 246,339. Bruhn, F. W. G. March 16, 1925. Counters actuated by reciprocating mechanism.-A counter intended particularly for displaying fares in a taximeter comprises numeral rings 22 - - 25 supported on a cage or frame rotatably mounted in a bracket 20. The units ring is driven step by step by means of a ratchet and pawl, and transfer is effected in the usual way by pinions 35 supported by a spindle 32 carried by the cage. The counting rings may be provided with type to record the fares upon a voucher strip 72 and a retained record-strip 74. The rolls for the strips and the ink-ribbons are arranged in top and bottom compartments 76, 85, and the knives 88, 89 in the central compartment with the hammer 87 and the counter. Zeroizing-mechanisrm.-The cage is provided with spring pins 54 which, when the cage is rotated to zeroize the rings, engage a shoulderon each ring and carry the rings forward to zero position, where they are stopped by spring-controlled pawls 56, Fig. 3, loosely pinned to the shaft 59 and adanted to enter notches in the rings. The rotation of the cage is effected by a rack 46 and pinion 51 under the pull of a spring 47 when a catch is disengaged from the rack. The descent of the rack thereupon through a cam rail 61 and an arm 60 rotates the shaft 59 sufficiently to free the pawls 56 for action, and a pin 63 rocks a cam 64 to force the transfer spindle 32 to the left, Fig. 6, to disengage, the pinions 35 from their lower rings.

Filed: 1954-03-11
Abstract: 783,090. Labelling machines. ROSE BROS. (GAINSBOROUGH), Ltd. March 10, 1955 [March 11, 1954], No. 7097/54. Class 73 Bottles 11 are fed to a label-applying station by a conveyer 12 moving in timed relationship with a rotatable support 18, 19, upon which is pivotally mounted a pick-up member 21 adapted to pick up a label from a stack 62 and apply it to the bottles. Further, means operating in timed relationship with the support and conveyer cause the member 21 to pivot in such manner as to maintain the label in engagement with the bottle at the applying station during a predetermined movement of the bottle, during which movement the deflection of the label round the bottle is initiated. In the construction shown, each member 21 is faced with a rubber pad 42 and pivots in an arm 33 which is pivotally mounted on the spider 18. The pads have suction openings which communicate through conduits with a hose 52 leading to the rotatable part 53 of a suction casing 53, 54, so designed that suction is applied when the members pass the oscillating label stack 62 and gumming device 63 and is released after the label is. applied to the neck of a bottle. The timed rotation of each member 21 at the applying station is effected by a fixed cam 28 against which bears, under spring action, rollers 27 on arms 26 of members 22, which members pivot on the spider 19 and have teeth meshing with a pinion 36 on the shaft of the member 21. By this means the cam serves to rotate the member 21 anticlockwise towards an approaching bottle as the latter nears the label-applying station. Specification 741,147 is referred to in the Provisional Specification.

Title: Improvements in or relating to the removal of excess water from aqueous slurries or suspensions
Inventor: JOHNSON JOHN ARTHUR
Filed: 1955-03-12
Abstract: 794,733. Filters. SERVICE (ENGINEERS), Ltd. June 11, 1956 [March 12, 1955], No. 7293/55. Class 46. Aqueous slurry (e.g., of the type that tends to settle out rapidly on standing such as coal slurry or pottery slip) is pumped by a pump 16, preferably a reciprocating pump of the construction described in Specification 677,136 [Group XXVIII], along a pipe 14, 18 leading from a storage receptacle 12 to a filter press 20, some, however, of the slurry being returned via a union 22 and a branch pipe 24 to the receptacle 12. Initially water can escape readily from the filter press and the pump encounters little resistance therein so that only a small part of the slurry passes along the pipe 24. Subsequently pressure rises in the press but the pump is enabled to maintain full output by escape of the greater part of the slurry along the pipe 24. Since the union 22 is close to the press, little settlement occurs except in the press. The branch pipe 24 ends in a nozzle 26 so arranged as to keep the slurry in the receptacle 12 stirred.

Abstract: 418,259. Oil engines. PIPPIG, F. A., 21, S. 7th Avenue, Mount Vernon, New York, U.S.A. March 13, 1933, No. 7593. Convention date, March 12, 1932. [Classes 7 (ii), 7 (iii), and 7 (iv).] In a heavy oil engine air is forced from the cylinder into a combustion chamber and supplied with a small amount of fuel to form a lean fuel - air mixture which is ionized by a non-igniting electrical discharge, after which additional fuel is injected into the chamber and its contents ignited. In the four-strokecycle engine shown in Fig. 1, air is directed by recesses 24 and channels 26 in the piston 22 through a tapered passage 37 into a combustion chamber 33 which is closed by a plug 30 having cooling fins 31. Air that traverses the passage 37 raises a ball valve 44 and induces fuel through a nozzle 41 to form a lean fuel-air mixture which is ionized by an electrical discharge across the terminals of a sparking plug 34. Towards the end of the compression stroke, heavy fuel is injected, by a pump, through the nozzle 41 and the mixture is ignited by a spark, which may be cut off after starting and the mixture is then ignited by the heat of compression. In a two-stroke-cycle engine using crank-case compression and pistoncontrolled inlet and exhaust ports, the head of the combustion chamber is resiliently mounted and the space above it is filled with a cooling medium. Ignition systems ; sparking plugs.-When the ignition switch 64, Fig. 6, is closed, current flows from a battery 63, (1) to a booster coil 62 and through a distributer 61 to supply an igniting spark to the sparking plugs 65, and (2) through a vibrating coil 66 and a distributer to provide the non-igniting discharge to the plugs 65.
