Abstract: 265,531. Bosch Akt.-Ges., R. Feb. 5, 1926, [Convention date]. Cylinders receiving liquid fuel. - In starting engines working with fuel injection, compression is reduced by restricting the admission of air during the starting revolutions, fuel being injected only after a certain number of strokes and into the low-pressure air charge in the cylinders. In one form, Fig. 4, the cylinder of a four-strokeengine is provided with an air-admission valve 0, a fuel-injection nozzle m, and an exhaust valve P. The air inlet conduit k is provided with a rotary valve t with ports r having V notches x and co-operating with ports in the valve casing D. In a multiple-cylinder engine, the valves t are connected to a single control lever. At starting, the valve) t is closed and the engine turned by an electric or other starter; the valve t is then turned to bring the notches x into register with the ports in the casing and, after several compression strokes, fuel is admitted through the nozzle m. When the engine has started, the valve t is fully opened. The engine piston i may be provided with an auxiliary combustion chamber y with a restricted opening z opposite the fuel nozzle m. In anothed form, the chamber y is omitted and the upper surface of the piston is slightly concave. In a two-stroke engine, Fig. 5, the auxiliary combustion chamber y is arranged in a cylinder head, or may be arranged in the piston or as a lateral recess in the cylinder.

Abstract: 557,463. Stereotype casting and' finishing. TRIGGS, W. W. (Wood Newspaper Machinery Corporation). May 18, 1942, No. 6729. [Class 100 (ii)] A stereotype casting and finishing machine is provided with power actuated means whereby, in succession and automatically, the plate is cast in a vertical two part mould, one part of the mould carrying the cast plate is tilted and transferred to an inclined runway, the plate is stripped from the mould to allow it to move by gravity down the runway to a finishing station, the plate is shaved and its tail severed at the station, and the plate released to permit further movement down the runway. The casting back 14, Fig. 1, is supported by rollers &c. 19 running on tracks 12, 21 and'is connected by links 62 to arms 61 on a shaft 59 which is rocked by a pinion 60, gear sector 58 on an arm 57 secured to a shaft 55 which is rocked by an arm 56 and cam 54 on a motor driven shaft 53. The parts operate to move the back 14 rearwardly after the plate has solidified to strip the matrix from the plate. The core 29 which, in casting position, rests upon a pivoted support 35 adjustable in height by a screw 39 and urged upwardly by a spring, is connected by linkage 75, 74, 72, 71, to an arm 70 on a shaft 68 rocked by Geneva gear 69 from the shaft 59 so that, after retraction of the back 14 the core is swung over so that the plate P rests on the rollers 79 of the inclined runway. Upon further movement of the core the plate is stripped from the core and slides down the runway into engagement with a stop 95 at the unit end of a finishing arch 94. A part of the runway at one side is then raised to clamp the plate in the arch and a circular saw and shaving knife then sever the tail T and finish the plate. The stop 95 is depressed before the completion of the sawing operation so that immediately the tail is severed it continues down the runway but before' this occurs a section 118 of the runway is pivoted downwardly by the action of a cam 117 on a driven shaft 116 so that the tail falls down a chute 122. The section 118 is then restored so that the finished plate can pass down to a cooling position in contact with a stop 124. After cooling this stop is moved clear of the plate by a cam 127 on the shaft 116 acting through an arm 126 and link 125. The metal is delivered to the casting box by a pump 81 actuated by linkage 83 85, 87 and bell crank lever 88 actuated by a cam 91 on the shaft 53.

Title: Improvements in or relating to electromagnetic vibrator systems
IPC: H02M7/62
Filed: 1955-03-08
Abstract: 780,615. Electromagnetic interrupters. ERICSSON TELEPHONES, Ltd., and SHILSING, J. March 8, 1955, No. 6731/55. Class 38 (5). [Also in Group XXXV] On closure of a key KS the driving magnet VDM is energized by D.C. through a self-interrupting contact spring V1 and a resistor-capacitor combination R1, C1 to vibrate a reedmounted armature (not shown). The capacitor C1 permits the initial current pulse to be high; however, the capacitor is rapidly charged and on the third and subsequent pulses all the current passes through the resistor R1 and thus has a smaller value. The high value of the initial pulse assists in starting the vibration. The armature vibrates contact springs V4, V7 to supply A.C. to a load R2 through contacts V3, V6 and V5, V8. A spark-quench circuit C2, R3 shunts the contacts V1, V2.

Abstract: 732,159. Automatic circuit-breakers. LANDIS & GYR AKT.-GES. March 11, 1953 [March 12, 1952], No. 6757/53. Class 38 (5). In an automatic circuitbreaker, a differential release means comprises an armature 11 carried on a leaf spring 12 and an electromagnet with opposing coils 8, 9. When the currents in the coils are unbalanced, the resultant magnetic field causes the armature to oscillate in step with the mains frequency and as the amplitude of the oscillation increases, the spring 12 turns a lever 14 so as to release a spring-biased latch lever 17. The lever 17 now unlatches a member 19 which opens the contacts 3, 4 under the bias of a spring 18. The circuit-breaker may have an instantaneous electromagnetic excess-current release 5 and a time-lag thermal overload release 6.

Casting-apparatus; feeding; delivery; moulds. -Comprises a machine for moulding bricks, tiles, &c. from cement, concrete, or other pasty material by means of compressed air. Material passes through a shoot D to a rotary measuring- device A intermittingly operated through ratchet mechanism by a gear E meshing with a sector w on a lever B, which is moved in one direction by a pin H on a cam F and in the other by a weight C. The divided material passes through a funnel into a receptacle a, from which it is adapted to be forced by compressed air into the mould b. The receptacle is fitted with a cover, which is closed by levers G, G<1> operated by the cam F. A shaft N carrying the cam F is rocked by a rod M operated from a main shaft t driven through worm gearing u from a belt shaft. Upon closure of the receptacle a, a cam on the shaft U opens a valve to admit compressed air to the receptacle and force the material through a passage N into the mould b, which is apertured for the escape of water. A cam P on the shaft U next opens an exhaust valve, after which the end S of the mould is turned down by a counterweighted hand lever T and the tile &c. is pushed out of the mould upon a bottom plate, on to a carriage by means of a pusher V, normally constituting one side of the mould, which is advanced by a rack X operated by a sector W loosely mounted on the shaft t and coupled thereto by a cam-operated spring clutch Z. After delivery, the member V is returned by the release of the sector W and its return by a weighted piston working in a cylinder P fitted with a regulating-valve q, and during the return the belt is moved to the loose pulley by the movement of the shifter h by a trip lever g.

Abstract: 363,910. Automatic-feed weighers; indicating-mechanism. TOLEDO SCALE MANUFACTURING CO., Monroe Street, Toledo, Ohio, U.S.A. March 12, 1931, No. 7623. Convention date, April 3, 1930. [Class 143.] In a weighing-scale adapted to control auxiliary mechanism such as material-feeding means, the control means comprise a wave-emanating source, an element activated by the waves, and means operated by the weighing-mechanism to interrupt the waves, Material is fed into a receptacle 41, Fig. 1, on the platform 5 of a weighing-scale from a hopper 56 by a screw rotated by a motor 53. The load is counterbalanced by a tareing-device and by a pendulous resistant. The weight of the material is indicated by a pointer 15, Fig. 3, carried by a spindle 11 and registering with a chart 17. A second pointer 14 registers with a chart 16 and may be set back relatively to the pointer 15 through an angle corresponding to the weight of material to be delivered into the receptacle. For this purpose, the pointer 14 is carried by a sleeve 27, Fig. 6, that is slidable on the spindle 11 and has a clutch member 26 normally pressed by a spring 29 against a similar member 21 on the spindle. To adjust the pointer 14, the sleeve 27 is retracted and rotated until the pointer 14 registers with the desired indication on the chart 16, the pointer 15 being meanwhile held in zero position by an electromagnet 31, Fig. 4, controlled by a pushbutton 32, Fig. 1. As the material accumulates in the receptacle, the pointer 14 rotates until it reaches zero position where it intercepts a beam of light proceeding from a lamp 38, Fig. 3, and passing through a condenser 39 and slit in the chart 16 to activate a light-sensitive cell 36. The cell thereupon acts to open the circuit of the motor 53 and apply a brake to the motor shaft to arrest the rotation of the feeding screw.

Title: High pressure mercury vapour electric lamp
IPC: H01J13/02
Filed: 1925-03-20
Abstract: 231,481. Mensing, K. March 31, 1924, [Convention date]. Metallic-vapour apparatus.- A high-pressure mercury-vapour lamp is directly cooled by water and comprises a silica tube the bore of which is reduced approximately to the apparent diameter of the arc, while the thickness of its wall is increased to about the same dimension, say 4-5 millimetres, so as to prevent condensation of mercury on the tube. Thus a high load and high efficiency may be attained without softening of the tube, the inner surface of which may attain a bright red heat. Only a small quantity of mercury is necessary. The steadying-resistance may be diminished so as only to absorb 5 per cent of the supply voltages, or may even be dispensed with. Such lamps after lighting may be used in any position. They may be employed for sterilization and for sub-aqueous illumination. Specification 23318/05 is referred to.
