Title: Improvements in pressing machines
IPC: D06F71/06
Filed: 1930-09-23
Abstract: 363,718. Ironing-presses. AMERICAN LAUNDRY MACHINERY CO., Norwood Station, Cincinnati, Ohio, U.S.A. Sept. 23, 1930, No. 28455. Convention date, April 18. [Class 138 (ii).] In a laundry or similar press operated by fluidpressure the power unit is energized by admitting the pressure to a valve casing for actuating the valve therein to close the exhaust port from the pressure cylinder and such valve is held closed only so long as the supply of pressure fluid to the casing is maintained. Two valves 21, 25 require simultaneous and maintained manual operation to permit fluid pressure to pass from a supply pipe 19 through a pipe 27 to a casing 28. The fluid pressure moves the valve 29 in the casing 28 against a spring 100, or against a spring which acts on a press-closing pedal which is linked to a bell-crank lever 48, to a position in which it closes the exhaust port 31 which is provided with a silencer 33. Fluid pressure passes from the casing 28 through a port 30 to the cylinder 16 of the power unit of which the piston rod 14 is pivoted at its free end to one of the usual'pair of press closing toggle links. As long as the handles 38, 44 of the valves 21, 25 are operated to maintain the supply through the pipe 27 the inlet 29 will be kept open and the exhaust port closed but when the handles are released the pressure of the fluid trapped in the system is insufficient to overcome the spring 100 or the spring associated with the release pedal and the inlet valve 29 closes, the cylinder exhausts through the port 31 and the press is returned to full open position by restoring springs. The Specification also describes means for admitting a supplementary supply of fluid pressure to the cylinder 16 after the press has been substantially closed as described in Specification 363,724. the full pressure then existing in the cylinder 16 being sufficient to maintain the valve 29 in the position wherein it closes the exhaust port 31 until it is moved to the position shown by depression of the release pedal, this movement of the release pedal simultaneously shutting off the supplementary fluid pressure supply.

Abstract: 407,753. Hydraulic shock-absorbers. BOUGHTON, E. B., EMMOTT, W., and BROCK, D. T., (trading as AUTOMOTIVE PRODUCTS CO.), Brock House, Langham Street, London. Oct. 13, 1932, No. 28631. [Class 108 (iii).] In an hydraulic shock-absorber, particularly of the rotary-vane type, in which flow of liquid through a passage 8 due to rotary movement of the vane 4 is restricted by an adjustable non-rotatable slide-valve 9, the valve is connected to a spring-pressed piston 11A which is acted on by the liquid in a pipe 14 communicating with a manually-adjustable control device, so that to vary the resistance of the shockabsorber the valve is adjustable automatically by temperature change in the liquid in the pipe 14 and manually by a screw-threaded piston- and-cylinder device 21, 24, 27 which varies the pressure of the liquid in the pipe 14 by varying the pressure of a spring 28 acting on a piston 22. Increase in volume of the liquid in the pipe 14 due to temperature increase is also partly taken up by movement of the piston 22 to compress the spring 28. A reservoir is provided by an outer casing 3 surrounding the body 1 of the shock-absorber, the body communicating with the reservoir through non- return valves 1A. Liquid leaking from the cylinder 12 housing the piston 11A is led through ducts 19 to the reservoir and liquid leaking around the spindle rotating the vane 4 is also returned to the reservoir. In a modification the piston 11A moves at right-angles to the valve 9, is spring-pressed in one direction, and has a cam-surface for adjusting the valve. According to the Provisional Specification a single manually-adjustable device mounted on the dashboard may control, for example, four shock-absorbers simultaneously.

Title: Improvements in a system for wireless regulation of a master clock and subsidiary clocks
IPC: G04R20/00
Filed: 1946-09-27
Abstract: 648,747. Electric selective signalling. PFEFFER, V. Sept. 27, 1946, No. 28885. Convention date, Sept. 27, 1945. [Class 40 (i)] [Also in Group XVIII] In a system of clocks including a master clock and a series of subsidiary clocks (see Group XVIII), means are provided for analysing the periodic correcting signals which are transmitted by wireless. The signal is in the form of four short impulses followed by a long one. The analysing means comprise a ratchet 45, having two toothed portions 45a and 45b and a cam portion 46 which normally abuts a stop 47. A pawl 50 carried by a toothed segment 51 is spring biassed into engagement with the teeth 45a of the ratchet wheel 45 but is normally held therefrom by a pin 52 and only engages them when the segment 51 is moved clockwise by a spring 57 when an electromagnet 63 is energized to attract its armature 61. A spring pressed pawl 53 moves into engagement with the teeth 45b when an electromagnet 56 is energized to attract its armature 54. Upon the reception of the first impulse of the time signal the electromagnets 56, 63 are energized and the ratchet wheel 45 is stepped on one tooth by the pawl 50. After each impulse the lever 61 returns the segment 51 and the pawl 50 to their initial positions. As the electromagnet 56 is of the delayed release type the pawl 53 keeps the ratchet 45 in the advanced position until the succeeding impulse and so after four impulses the ratchet 45 has advanced clockwise four teeth. When the final long impulse arrives the electromagnets 56, 63 are again energized, the lever 61 moves down, the segment 51 swings clockwise and the pawl 50 engages the last tooth. The segment 51 is stopped by the lever 61. The projection 46 closes the blade spring contacts 49 whereupon an electromagnet 70 is energized to attract its armature 67 and a second toothed segment 64 is moved clockwise. The downward movement of the lever 67 rocks a cam lever 71 to allow a spring-biassed pawl 73 to engage the periphery of the segment 64. At the end of the last impulse the pawl 73 moves into the recess 65 and the blade spring switch 74 closes whereupon an electromagnet 31 is energized to effect correction of the master clock. The ratchet 45 may be replaced by a contact carrying segment and the segment 64 moved throughout the duration of the whole signal, Fig. 2, not shown. Specification 650,611, [Group XVIII], is referred to.

Abstract: 894,283. Electric selective signalling systems. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Aug. 26, 1960 [Aug. 26, 1959], No. 29158/59. Drawings to Specification. Class 40 (1). In a continuously scanning remote-control or indicating system, e.g. of the type described in Specification 886,663, transmission from a remote area to a control office takes place according to any one of at least three distinctive modes, which, with the exception of one, serve as indication codes, the excepted one prevailing automatically in the absence of either or any one of the others, and the control office is arranged to respond thereto to display that a fault is present in the associated step of the scanning cycle. The system may be included in a railway signalling system in which the conditions of track circuits are examined in turn, one of two frequencies being transmitted to the control office according to whether or not a track section is occupied, or no signal being sent if a fault develops, e.g. if a switch stops in an intermediate position. The control office detector includes a pair of bi-stable circuits which are switched to the " on " state when the associated frequency is received and operate a respective relay in an indicator, neither relay being operated if a fault is detected. The system may also be used to effect control of remote apparatus, the control office transmitting one of two frequencies or nothing to a remote area including a detector having two bi-stable circuits, so as to effect one of three control operations, the " blank " control signal being used to perform a restrictive operation, e.g. setting a signal to danger.
