Title: Improvements in or relating to tilting mechanism for vehicles
IPC: B60P1/14
Filed: 1920-05-28
Abstract: 143,913. Wood, G. A. March 15, 1915, [Convention date]. Tipping-wagons.-Relates to hydraulic apparatus for lifting the bodies of tipping-wagons, and comprises more particularly the provision of an expansion chamber or tank at the upper end of the cylinder which, together with the cylinder and a hollow piston rod reciprocating therein, forms a storage reservoir for the operating liquid. The invention also comprises means for connecting the piston rod to the vehicle body, and means for mounting the cylinder and operating pump on the chassis. The cylinder 10 is screwed at 11 to a base-plate 9 secured to a transverse frame 8 preferably of angle-iron, and is reduced at its upper end to form a seating 18 for a chamber 12 which is secured on the cylindar by a screwed flanged ring 20, the cylinder walls being provided with apertures 13, 14 leading into the chamber 12. The hollow piston rod 22 is closed at its upper end 24, and its lower end screws on to a boss 25 on the piston 26 which may have a stud 29 projecting from its lower end to engage the base 9 when in the lowered position. The upper end of the piston rod communicates with the atmosphere by means of a tube 31 after the piston rod has been slightly raised. In a modification, the upper end of the piston rod communicates with the atmosphere through a valve which is closed by a float when the liquid approaches the top of the rod. The lower end of the piston rod communicates with the cylinder through apertures 30. Liquid is forced from the chamber 12 through the pipe 17 and passage 49 to the underside of the piston, by means of a gear pump 36 carried by the plate 9 and driven by the propeller-shaft 39 through a clutch 40 which is actuated bv a lever 41, link 42, and hand-lever 43. The shaft 39 passes through the hub of the gear wheel 52, and sufficient play is allowed between the shaft and wheel to permit depression of the cross-bars 8 under the load. The pump is fitted with a valve 54 operated by a lever 45, link 46, and hand lever 47. The upper end of the piston rod is provided with a cross-bar 60 from each end, of which a pulley 66 is suspended, by means of pairs of shackles 62, 64, arranged to swing in planes at right-angles to one another. Cables 71 passing over the pulleys are attached at one end to brackets 72 depending from the vehicle body 4, and at the other end to an equalizing bar 69 pivotally mounted on a shackle 63 secured to the plate 9.

Patent GB-166423-A (GB)
Title: Improvements in dynamo-electric machinery
IPC: H02K23/42
Filed: 1920-05-28
Abstract: 166,423. Walker, M., and Metropolitan- Vickers Electrical Co., Ltd. May 28, 1920. Pole-pieces; exciting.-The air-gap of a generator is increased from a very short length near the pole tip Al, Fig. 1, first encountered by the armature bars to a greater length at the other tip At in such a manner that the armature ampereturns at full load or other predetermined load which would normally cause distortion are absorbed in producing a nearly uniform density throughout the gap. The gap length is so adjusted that the armature ampere-turns between the pole centre and the tip At when added to the ampere-turns on the pole are only sufficient to produce a flux density in the armature teeth under that tip which is considerably below a supersaturation value, namely about 20,000 lines per sq. cm. The consequent reduction of flux under the tip Al is less than the increase under the tip At, with the result that the effective gap flux at the predetermined load is greater than that at no load instead of being less as is usually the case. Calculations are given in the Specification showing how to determine the distance from the tip Al at which the grading is to begin and how to obtain the gap length at any point on the pole arc. In machines of high armature strength it is shown that the method of grading the gap enables a compensating-coil of relatively few turns to be employed. The coil may be applied as in Fig. 3, in which A<1> is the normal field-coil on the pole A, the tip of which is bevelled, at E<1>, E<2>, E<3> to give a graded gap. The pole has two slots C<1>, C<2> in which the compensating-coils D<1>, D<2> are wound, both coils being carried around the commutating-pole F. Alternatively, each compensating-coil D<1>, D<2>, Fig. 4, may embrace the leading tip of one pole and the trailing tip of the adjacent pole. In the case of motors, the grading of the gap, as above described, is reversed with regard to the direction of armature rotation.

The electrodes are connected to binding posts mounted in plate 7 and leads 21 provide the external connections. The front of the rows may be provided with a rubber cover 25 and the space between the crystals and the cover may be filled with liquid to transmit the vibrations. By providing separate connections to each row of crystals they may be made to vibrate in differing phases and the direction of the resulting beam can thus be adjusted. Specification 636,313 is referred to.
Patent GB-317526-A (GB)
Title: Improvements in or relating to tripping mechanism of rotary printing machines
IPC: B41F33/08
Filed: 1928-05-18
Abstract: 317,526. Linotype & Machinery, Ltd., and Dowson, R. May 18, 1928. Tripping-arrangements.-A multicolour rotary printing-machine in which the work is fed in succession through printing couples such as offset cylinders 2, 2<a>, and impression cylinders 3, 3<a>, is fitted with trip mechanism which trips each couple successively after it has printed the sheet last fed. The tripping-devices are constructed so that either of the couples may be tripped independently of the other, and sheetfeed tripping-devices also are employed which may be operated to prevent feed if the first printing-couple is tripped, or the sheet-feed tripping-devices may be prevented from being actuated if it is desired to print a sheet by the second couple only. The offset cylinders 2, 2<a> are operated by similar trip mechanism comprising eccentrics 10, 10<a>, connected by adjustable links to lever arms 9, 9<a> on trip-shafts 7, 7<a>, which are rotated, when desired, by oscillating pawls 12, 12<a>, 13, 13<a>, connected by curved links and controlled by levers 19, 19<a>, the lever 19 being actuated by yielding lever-and-link mechanism 23, 22, 21, 20 from a pedal 8. The lever 19<a> is operated from the trip shaft 7 owing to a yielding lever-and-link connection 30, 21<a>, 22a, 23<a>, and the levers 19, 19<a> so control the pawls that on depression of pedal 8 the cylinder 2 is tripped by the engagement of pawl 12 with an abutment on a sector 6 rocked by a cam on impression cylinder 3, the cylinder 2 being tripped after an impression is completed. The succeeding cylinder 2<a> is tripped when a further impression has been produced on the same sheet. The sheet-feed tripping-devices are of the kind set forth in Specification 288,405 and comprise a stop-shaft 25 which is connected by a link 27 and lever 28 to the pedal trip, so that when this is operated, the oscillating gripper feed is also tripped. A lay shaft which interposes a stop in the path of the sheet to be feed is also operatively connected to lever 9 so that the stop is raised when cylinder 2 is tripped. The connections between the cylinder and feed trips can be adjusted so as to permit the cylinder 2 to be tripped without actuating the feed trips, so that a sheet can pass from cylinder 3 to 3<a> and be printed only by the second couple. The lever 19<a> can be held permanently by a pin 48 in positions corresponding to the tripped and untripped positions of the couple 2a, 3<a>, so that it is possible to print in single colour from either couple as well as in multicolour. The eccentrics 10, 10<a> are connected to ink-tripping devices to prevent double inking of the plates when the printing-couples are tripped.

Title: Fuel injection pumps
IPC: F02M59/36
Filed: 1937-05-27
Abstract: 497,933. Fuel - injection pumps. GAMBRELL, E. C. May 27. 1937, No. 14759. Convention date, June 3, 1936. [Class 102 (i)] A fuel-injection pump comprises a piston which is in three parts 13, 62 and 55 which are rotatable relatively to each other and reciprocated as a whole by the cam 58. A plunger 22 having a head 37 is arranged in a bore in the piston 13, 62, 55 and is loaded by a spring 48. During upward movement of the piston, liquid. is discharged from chamber 12 to chamber 35 through the port 39 until an edge 38 closes the port 39. The part 13 of the piston is rotated by the rack 46a and thus determines the injection pressure. Liquid pressure in the chamber 12 acts on the head 37 and forces the piston 22 downwards until the edge 49 closes the fuel suction port 26 and determines the quantity of fuel trapped in the bore 52 until the inclined slot 54 aligns with the discharge port 53 when the plunger 22 expels the charge. The piston part 55 is rotated by the rack 46c and determines the time of the beginning of injection. A pin 21 in the piston part 62 passes through a slot 20 in the plunger 22 and the piston part 62 is rotated by the rack 46b to adjust the plunger 22 and vary the amount of charge that is trapped in the bore 52. The space 12 is closed by a spring-loaded piston 33 controlling a port 34 leading to the chamber 35. The spring pressure may determine the maximum pressure in the chamber 12. The spring pressure may be adjusted so that the port 34 is opened at each stroke and a restricted amount of liquid allowed to escape from the chamber 12 so that the injection pressure then bears a relationship to the speed of the engine.

[Classes 83 (ii) and 83 (iv)] [Also in Group XIII] Uniting by fusion.-A pan a is provided with a jacket b by securing an annular member of tubular form to the pan, and then welding the jacket to this member. The pan may be lined with glass or enamel, or may be heat treated. The bases g, i of the pan and jacket are formed separately and secured to the body portions by welds h, j, respectively. The upper edge n, Fig. 1, of the jacket b is swaged inwardly to rest on the spacing member k, the jacket being lowered into position from above before the base i and a tube p, which is secured to the edge of the pan, are welded in position. In a modification, the spacer k, Fig. 3, rests on the wall of the jacket b, the latter being raised into position from below. A flange q to which a cover may be bolted is bent up from angle iron, welded to the pan, and machined to the final shape. An inlet connection is secured by welds s. Welded on bosses d, e, f, Fig. 1, receive fittings such as a steam inlet and condenser cock, a safety valve, and an air release cock. The tubular member k may form the means for introducing steam or other fluid to the interior of the jacket, the nozzles being disposed, or baffles being provided to prevent steam impinging on local points on the pan body. The spacer k may be filled with water during welding, to cool the work. Specification 436,760 is referred to.

Filed: 1973-03-28
Abstract: 1425896 Light guard VISOMAT-GERATEGmbH 28 March 1973 [28 March 1972] 14843/73 Heading G1A In a photo-electric guard a pulse generator 2 drives a series of light emitting diodes 1 (only one shown) to produce a series of beams and a corresponding series of photo-detectors 3 receive the beams after they have been reflected by retroreflectors 11 and semi-reflectors 12, the detectors outputs being processed by logic circuitry to determine if one or more of the beams has been interrupted. Reference signals from the pulse generator 2 and the output signals of the detectors are fed to a NAND gate 6 and a NOR gate 7. The outputs of the gates 6 and 7 therefore alternately change the states of a flip-flop 8, that is, if none of the beams has been interrupted. The squarewave pulses from the flip-flop 8 are fed via a frequency divider 9 to an amplifier 10 having a D.C. coupled output supplying a thyristor connected so that the machine is switched on except when unauthorized entry into the protected zone is detected. When one or more of the beams is interrupted the flipflop NAND and NOR gate outputs are no longer identical so a lamp L is switched on via a further NAND gate indicating the beam interruption.
