IPC: F04B49/20
Filed: 1928-09-07
Abstract: 297,421. Flottmann Akt.-Ges. Sept. 21, 1927, [Convention date]. Regulating compression.- In the regulation of compressors driven by internal combustion engines, a reduction of pressure automatically effected in the compressor suction pipe acts on a member controlling the fuel supply. The engine 2 drives the compressor 1 which supplies the receiver 4 through a pipe 3. A pipe 11 admits air from the receiver to the casing 10 of a piston valve 14 controlling a throttle valve 19, Fig. 2, in the compressor suction pipe 5, and also admits air behind a small piston 12, Fig. 3, of the fuel regulator. A pipe 9 leads from the compressor suction pipe to the fuel regulator cylinder 23, in which the large piston 8 moves to actuate the carburetter throttle through the rod 25. The maximum reservoir pressure can be controlled by adjustment of the spring 13, Fig. 2. When this pressure is exceeded, the piston valve 14 is moved leftwards by the air entering by the pipe 11, until bores 15, 16 in it and a passage 18 in the cylinder 10 allow the air to raise the piston of the throttle valve 19. The diminution of pressure thus caused in the suction pipe is transmitted through the pipe 9 to the piston 8, allowing it to be retracted by the spring 24. When the receiver pressure falls sufficiently, the spring 13 returns the piston valve 14, and a bore 27 in this valve vents the space below the throttle valve, which is returned by its spring. A motor in which the fuel is injected into the cylinders may be employed.

Filed: 1969-05-20
Abstract: 1,253,626. Wells &c. BYRON JACKSON Inc. 20 May, 1969 [10 June, 1968], No. 25777/ 69. Heading E1F. An anchor assembly for a well packer or bridge plug comprises upwardly and downwardly holding slips 20, 21 movable against a well casing C by conical expander surfaces 46, 47 on a mandrel 9 and coupled together for movement as a unit relative to the surfaces, by cross bars 34, 35 and an inner mandrel 33 slidable relative to the mandrel 9, Fig. 3. Alternatively, the inner mandrel may couple the surfaces 46, 47 together for movement as a unit relative to the slips. The bars extend through slots 37, 42 in the mandrel 9 and through a lost motion slot 49 in a control member 1, extending upwardly, Fig. 1a, through a packing body 7 fixed to the mandrel 9. When the packer has been run into position in the well, the control member which comprises a control head 3 and a connector head 48, assumes the intermediate position shown in Fig. 1a wherein spring urged valve members 80, 83 carried by members 59, 50 attached to the mandrel 9 and co-operating with flanges 86, 87 on the control member are both in an open position. When the well fluid pressure below the packer increases the packing body 7 moves upwards relative to drag blocks 13 on the mandrel 9 so that the upwardly holding slips 20 are forced against the casing by the surface 46. When the fluid pressure above the packer increases, the packing body is depressed so that the downwardly holding slips 21 are moved against the casing by the surface 47. To test set the packer, the control head 3 is raised so that fingers 96 on the head are lifted clear of co-operating slots 95 in the member 59. The control head is given a quarter-turn relative to the member 1 against the force of a torsion spring 100, so that the bottom ends of the fingers 96 seat on shoulders such as 104 on the member 59. The control head 3 is depressed under torque so that the mandrel 9 and surface 47 move the slips 21 against the casing. the elongated slot 49 in the control member 1 taking up the lost motion relative to the crossbar 34.

Patent GB-259267-A (GB)
Abstract: 259,267. Marks, E. C. R., (Elliott-Fisher Co.). June 2, 1925. Attachments and connections to typewriters. - In a keyoperated machine having a relatively movable frame and carriage a plurality of line totalizers is mounted on the carriage and these totalizers are operated by means associated with the operating means for the column totalizers on the frame. Control means is provided for determining whether any or all of the line totalizers shall operate and the character of such operation. Means are also provided to lock the keys when the line totalizer is not in a condition for operation, the keys. being unlocked by an operation of the usual restoring mechanism of the totalizers. The invention is shown applied to an Elliott-Fisher book-keeping machine with a plurality of column totalizers 9 mounted on a bar 8, Fig. 1, actuated by a master wheel 4 mounted on the movable carriage. At one end of the carriage two line totalizers 10, 11 are mounted, the master wheels 12, 13 of which are movable longitudinally on shafts 14, 15 connected through corresponding reversing mechanism 17, 18 to the shaft 16 of the master wheel 4. The reversing mechanisms are automatically controlled by levers 19, 20 coacting with control stops 21, 22 carried by the control bars 23, 24. The master wheels 12, 13 are mounted in carriages 25, 26 slidable on a guide-bar 27 by means of an arm 29 on a vertical shaft 28 and a second arm 30 thereon engaging stops 31 on the control bars. When either of the line totalizers is not in a condition for operation, i.e. when the master wheels are moved out of register, the keys are locked. Associated with the master wheel carriages are two semi-circular bars 33, 34. one fixed to each carriage. The bar 33 of the carriage 25 is provided with a notch 35, Fig. 10, which, when the master wheel 12 is in the disengaged position, is engaged by a spring-controlled locking plate 36, Fig. 3. At the same time a cam tooth 47 on the bar 33, Figs. 3 and 15, engages a tooth 46 on a lever 42 pivoted at 43 so as to swing the end 44 of the lever into alignment with the T-shaped ends of the crowding key locks 7 thereby locking the key levers. The release of the plate 36 is effected by depression of the usual restoring member 32 which resets the totalizer transfer mechanism, a pin 40 on the said member 33 engaging a slot 41 in the plate 36. To prevent the actual release of the key levers until the end of the restoring movement the lever 42 is provided with a down-turned end 48 which is engaged by a lever 49 on the initial movement of the restoring member 32, a cam slot 51 in the lever engaging the pin 40 on the member. To lock the corresponding totalizer out of action the master wheel 12 is given an additional step movement beyond the numeral wheels whereupon a master wheel lock 53, Fig. 5, engages a notch 52 in the bar 33. By this movement the keys are unlocked and capable of independent use. The bar 34 associated with the master wheel carriage 26 of the totalizer 11 operates in a similar manner to the bar 33.

Abstract: 900,177. Marking apparatus. MASSON SEELEY & CO. Ltd. Aug. 10, 1959 [Aug. 13, 1958], No. 26043/58. Class 100 (2). Marking apparatus, e.g. for articles of strip, rod or tubular form, includes a rotatable support for a die or dies, a work support spaced from the die support and capable of movement with the work whilst marking takes place, means for heating a die when mounted on the die support and means for guiding,and feeding marking foil between the supports. As shown, the machine has a frame including a vertical plate 2 on which are mounted, in horizontallyprojecting position, die and work supports 4, 5, respectively. The die and work supports comprise tubular sleeves 31, 56, respectively, rotatably mounted on stub-shafts secured to the plate 2, the position of the work support stubshaft being vertically adjustable, to accommodate different sizes of work, by a screw 49. Plates 57 are mounted at each side of the work support and are vertically movable therewith. An annular die 58 having elevated marking portions 59 is mounted on the sleeve 31 to which is secured a gear 35. A thermostaticallycontrolled heater element is mounted in the die support stub-shaft. Foil 67 is fed from a supply spool 66, round guide rollers 10 and beneath the die 58 by feed rollers 13, 19, and is taken up on a spool 68 mounted on a take-up roller 9. The roller 13, is driven through an electromagnetic clutch and a variable speed gear-box by an electric motor, and a gear 22 secured thereto meshes with the gear 35, whereby the drive is transmitted to the die 58. A belt and pulley drive connects the roller 13 and the take-up roller 9. The drive to the die and foil may be continuous in which case marking of the strip, rod or tube is effected at intervals corresponding to the spacing of the elevated portions 59 of the die, the work being fed continuously between the die and work supports and the peripheral speed of the die being synchronized with the linear speed of the work. Alternatively, the electric motor may be driven continuously and the electromagnetic clutch only intermittently so that between actuations of the clutch the elevated portions 59 are stationary and out of the path of the continuously moving work; in this way markings may be produced on the work at longer intervals. The clutch may be controlled by a photo-cell placed downstream of the apparatus so that the last mark made on the work in passing the cell actuates the clutch, or by a cam-operated micro-switch. Instead of a rotatable work-support a reciprocating worksupporting table may be used.

[Class 38 (iv).] A lighting installation, particularly suitable for road illumination, comprises a plurality of gas-filled discharge lamps each with an incandescent cathode and each operated through a transformer with the primary circuits of such transformers in series. In one arrangement, Fig. 1, each lamp comprises an envelope 1 with a filling of sodium vapour and a rare gas, a cathode 2 supplied with heating current from a portion of the secondary winding 5 of the corresponding transformer and two anodes 3 connected through resistances 4 one to each end of the winding 5, the primary windings 7 being connected in series and fed from a transformer 8. Each cathode is coated with an electron-emitting layer, e.g. of an alkaline earth oxide, to keep the temperature of electron emission low.. The resistances 4 may be arranged to heat the envelopes 1 to increase the vapour pressure. In another arrangement, Fig. 2, economy is effected by the use of autotransformers 9 each in series with a steadying resistance 13. In this case each lamp may comprise two cathodes 11 which may be heated indirectly or by connection, as shown, to end portions of the transformer windings and two anodes 12 which may each be connected as :shown to one pole wire of the adjacent cathode or may be supplied through separate conductors. The transformer windings between the points 15, 16, which are not traversed by the discharge current, may be of thinner wire than the rest of the windings. Preferably each transformer is bridged by normally open shunt which is closed automatically if the corresponding lamp becomes defective. To increase the number of lamps without increasing the tension of the feeding transformer 8, the supply conductors may be connected to tapping points on the autotransformer windings.
