Abstract: 570,994. Door catches. ESSOR MANUFACTURING CO., Ltd., PERKINS, J. B., and EGAN, H. B. J. Sept. 2, 1943, No. 14316. [Class 44] A spring catch for doors, &c. comprises a bolt in two pieces 4, 5 screwed together so that the overall length of the bolt may be adjusted to vary the extent to which a roller 8 carried by the bolt is projected by a spring 6 towards the fixed keeper 13 with which it engages, this adjustment being effected from the rear end prior to fixing the device in place, and requiring removal of the device to effect alteration in the adjustment. Piece 4 has a flange 11 slidable in a cylindrical case 1 open at both ends, the outer end having a pair of oppositely directed lugs, not shown, to which an apertured cover-plate 3 is secured, plate 3 having an aperture through which roller 8 projects, extensions of the aperture receiving a pair of parallel arms 7 on piece 4 between which the roller is mounted, piece 4 being thus held against rotation in its projected position. When the roller is pressed inwards as in closing the door, rotation of piece 4 is prevented by a slot 12 in flange 11 engaging a rib or projection 14 in the casing, so that arms 7 do not get out of register with the aperture in plate 3. Boltpiece 5 is adapted to screw more or less into piece 4 and has a head 16 with slot for engagement by screw-driver or the like inserted through the near end of the casing. The head 16 serves to limit the outward movement of the bolt by its abutment against an internal shoulder 17 formed in the casing, and itself forms an abutment for one end of the compression spring 6, the other end of the spring bearing against an inturned lip at the end of the casing, or against a washer retained by the lip. The device is inserted in an aperture in the door edge and is retained by screws passed through the plate 3.

Filed: 1926-06-09
Abstract: 269,754. English Electric Co., Ltd., and Wilson, J. C. June 9,1926. Protective or safety devices, auxiliary.-To prevent overspeeding of a dynamo-electric machine acting wholly or in part as a continuous-current generator, means, responsive to the speed or to conditions which would result in a rise of speed, are provided to short-circuit the whole or a part of the regulating resistance in the shunt field circuit. The invention is particularly applicable to motor generators or rotary converters which are liable to run as continuous-current motors (if in parallel with other machines) when the circuit breaker on the motor side is opened. The field resistance mav be short-circuited directly or through a relay by centrifugal means, a reverse current device or by an interlock on the alternating-current circuit breaker. The Figure shows a centrifugal device comprising a weighted lever 4 pivoted to the shaft 1 and 2 and normally held in position by a spring 3. At a predetermined speed, the lever strikes a crank lever 5 pivoted at 6, and releases a catch 10 whereby the spring 14 moves the contactor 12 to short,- circuit contacts 13 connected to the terminals of the field resistance.

Title: Hydraulic advancer for tubs
IPC: B61J3/08
Filed: 1964-04-09
Abstract: 1,025,496. Propelling mine cars. G. DUSTERLOH FABRIK FUR BERGWERKSBEDARF G.m.b.H. April 9, 1964 [May 30, 1963], No. 14691/64. Heading B7L. An hydraulic advancer for mine cars has two actuators 16, 19 interconnected by hydraulic transmission 14, the actuator pistons 17, 20 moving faster at the start of the forward stroke and throughout the return stroke than during the rest of the forward stroke, the advancer having a control valve 22 controlled by the pressure of fluid acting on pistons 29, 33. A main pump 3 and a feed pump 4 pass fluid back to a tank 10 via lines 6, 7, 11 and valves 8, 9, 5 until, to operate the advancer, valve 5 is closed causing a pressure build up in line 11 to cause valves 8, 9 to deliver fluid from the pumps to lines 12, 13. From line 12 fluid passes through valve 15 to move piston 17 and fluid displaced by piston 17 with fluid from lines 13 and 13A and transmission 14 acts through duct 18 on piston 20 to rapidly return the piston. Fluid from ahead of piston 20 passing to tank 10 via valves &c. 15, 21, 22, 23, 24. When piston 17 passes line 25A, fluid acts via shuttle valve 27 on piston 29 to reverse valve 22 against a weak spring 30. Piston 20 then has applied to its right-hand face fluid from ahead of piston 17 via lines &c. 18, 14, 13, 22, 21, 15 and fluid from pump 4 via lines &c. 7, 13, 22. When piston 17 passes duct 18 pressure builds up in line 31 and causes piston 32B to change over valve 15. Pressure fluid in transmission 14 acts via cylinder 19, line 25B and shuttle valve 26 on piston 29 and as the same pressure acts on piston 33, the spring 30 changes over valve 22. Only main pump 3 delivers fluid to piston 20 via valve 15, the piston therefore advances at normal speed. Fluid displaced by piston 20 acts via lines &c. 18, 34, 31, together with fluid from pump 4 via lines &c. 7, 9, 13, 14, 34, 31, to rapidly return the piston 17; when piston 17 passes duct 18 the fluid passes directly through this duct into actuator 16. The cycle then repeats. Should the advancer be overloaded, the fluid from pump 3 is returned to tank 10 via valve 8. The actuators have several closable bores where line 25 can be connected to adjust the stroke of the advancer.

Title: Improvements in or relating to apparatus for acting in turn on sheets
IPC: G06M9/02
Filed: 1957-05-09
Abstract: 896,410. Selective printing. ABELL, G.E.B., PRICE, P. R., CHADDER, H. L., and HEALEY A. C. Aug. 11, 1958 [May 9, 1957; Aug. 28, 1957], Nos. 14824/57 and 27161/57. Class 100(4) [Also in Group XIX] Record documents 50, Fig. 5, such as bank account cards are permanently mounted radially in a file which can be rotated by shaft 52 to bring the documents in turn into contact with sensing and recording units 53, 54, the sensing and reading operations being effected without detaching the document from the file. Transaction documents or cheques 55 are sensed by senser 56 and the sensing unit 53 searches through the documents 50 until the corresponding account number is found. The amount sensed from the cheque 55 is then added or subtracted in unit 57 and the new balance is recorded by unit 54. The sensing and recording units each comprise a separating device which consist of a suction tube 12, Fig. 3 rotating to curl the end of the document round itself. The first document is then separated from the next by a bar 13 carrying a blade 14 which rotates on the dotted line path, passes behind the document and causes the trailing end to be drawn across an arcuate backing member 15. This carries sensing or recording means in a row of holes 16. The member 15 is of insulating material and may have further suction ports holding the moving document closely to itself. For a marking unit each hole 16 may contain a capillary tube 17, Fig. 2, surrounding a glass fibre 18 having a beaded end 19. The tube is filled with ink for example a magnetic ink and a high potential is applied to the ink which is accordingly transferred from the bead 19 to the document. By using rapid short pulses the nib can be so placed in spots as to write the desired character. Alternatively the member 15 may have a depression for a carbon ribbon and a series of pins or stylii operated by solenoids making legible marks. These marks may be magnetic. The marks may be formed merely by electrical energization of the pins. The ribbon may be dispensed with, the marks being made in specially treated paper by electric pulses applied to the pins. Instead of a single row of pins actuated in successive positions along the line of movement of the paper, an array of pins may be provided, e.g. in five rows. Selected pins are operated to print the required characters, the operation being so quick that the relative movement of the paper does not cause smudging. In another modification the use of an oscillating stylus is suggested which is actuated at appropriate points to make the desired marks and the use of ordinary type or a magnetic recording head is mentioned. In the last case the documents 50 may carry a magnetic tape, be of magnetic material, or a film coated with such material. Specifications 606,130, 606,133, 707,736, 784,209 and 876,626 are referred to.
