Title: Improvements in the electric operation and control of railway points
IPC: B61L21/06
Filed: 1926-04-07
Abstract: 250,929. General Railway Signal Co., (Assignees of Prescott, C. W.). April 16, 1925, [Convention date]. Electric operation and control.-An electric points-motor has the driving- mechanism connected to the points by a slip-coupling so as to allow the points to be trailed through, the members of the slip-coupling having a positive engagement which is broken by an excessive force. The motor 1, Fig. 1, drives a friction clutch 2 and main gear M having a pin and roller connection 17 with a slotted lever L which is coupled to a sector S in engagement with the points rod 46. The lever L has a spring-pressed roller 37 engaging notches 48 - - 50 in the sector S to form a slip-coupling. Sector S has a cam 54 which actuates a contact block 61 to reverse the track circuit polarity. Main gear M has a two-level cam 8 engaged by a spring-pressed follower 12 which actuates a contact block 66 in the circuit of the pole-changer magnets 77, 78. Ma.in gear M also has cams 7, 9 engaging a lever 10, 11, 14 which actuates a contact block 67 for the motor circuit and motor-brake circuit. Block 67 is also actuated by the magnets 77, 78. The hand-lever 91. Fig. 6, is pivoted at 92 and carries a lever 93 which actuates a switch 95. The handlever 91 has a push-button 111 connected to a pin 113 engaging a slot 102 in a disc 99 pivoted at 92. A guard 116 retains the pin 113 in its depressed position when the disc is rotated, while the disc has a stop 100 locked by a lever 107 which is released by a handle 110 or magnet 109. The track relay T actuates a contact 166 to energize indication lamps N, R showing the position of the points. A double current relay D prevents the points from being moved when the track circuit is not clear. The points may be reversed at any part of their stroke through the switch 95 and and magnets 77, 78. In a simpler lay-out, the magnets 77, 78 may be omitted and the clutch 2 tightened or omitted. If the points are obstructed or trailed through, the indication given by the lamps N, R is at variance with the position of the lever 91, and warning is thereby given. The push-button 111 is used when the switch points are to be returned to normal position automatically after they have been passed, the disc 99 and lever 91 being returned to normal when magnet 109 is energized. Relays may also be provided for indicating the presence of a train in the circuit, worked in conjunction with an additional contact block actuated by the sector S.

Title: Machine and method for controlling the torque and speed of an agitator
IPC: D06F37/36
Filed: 1965-03-05
Abstract: 1,084,683. Agitators; driving. EMERSON ELECTRIC CO. March 5, 1965 [March 12, 1964], No. 9561/65. Heading B1C. [Also in Divisions D1 and F2] An oscillating agitator 3, Fig. 1, of an agitating machine, such as a washing machine, is driven by an oscillating type hydraulic motor 5 which is actuated by a hydraulic supply through a pipe 6 from a constant delivery pump 7 driven by a constant speed electric motor 8. A valve device 20 (see also Fig. 3) regulates a bypass to a reservoir 10 from a pipe 13 to outlet 14 to control the supply to the motor 5. The device 20 also includes a torque sensing device and a speed sensing device for the agitator. The former comprises a differential piston 60 which is urged to the right by the pressure in pipes 6 and 13, which is a function of the agitator torque, to tend to close the bypass from 13 to 14. This results in a greater flow to motor 5 and a consequent increase in speed thereof. This increase in speed is reflected in an increase of pressure drop across an orifice 55 from the motor outlet pipe 11 to a pipe 12 to reservoir 10 which acts on the end of piston 60 to tend to move it back to the left against spring 50 and the pump pressure to restore a balanced condition with the agitator operating at a higher speed. In a modified arrangement the speed sensing orifice is arranged on the input side of the hydraulic motor. It is stated that a variable output pump could be used the output of which is controlled instead of the bypass arrangement. The agitator could be of the planetary type or the reciprocating vertical type or it may be the tub 2 of the machine.

Title: Single motor driving device, more specially for grab bucket
IPC: B66C3/12
Filed: 1953-04-10
Abstract: 774,514. Winch control. VENOT & CIE., and DURAND, A. L. H. April 10, 1953 [April 11, 1952; Dec. 18, 1952], No. 9783/53. Class 78 (5). A control for a grab-bucket 65 includes a motor A which drives differential gear J, the two-output elements of which respectively transmit drive to winch drums B and C, there being a variable gear interposed in said transmitted drive. Thus, motor A drives differential gear J having output gear K and output shaft 60. The gear K drives opening cable H through gear 61 and drum C. Shaft 60 drives closing cable G through gear 52 of double differential gear 63 and through gear 64. Varying the gear ratio of differential gear 63 is effected by solenoid T which causes either brake S or brake R to be applied. Thus, by appropriate braking, the tension of cable G is increased to close the grab-bucket 65 or the tension of cable H is increased to cause the grab-bucket to open, this being effected when the motor is operating and the grab-bucket is moving. When the motor is stopped, brake V is employed in the opening or closing of the grab-bucket. The relative movements of the two drums may be damped by springs.

Abstract: 1,010,154. Knitting machines; testing and inspecting fabrics. L. T. F. BRYAN. March 6, 1964 [March 12, 1963], No. 9831/63. Headings D1C and D1S. [Also in Division G1] In apparatus for detecting flaws in fabric leaving a knitting machine, by scanning a detector across the fabric, the detector is arranged so that on actuation thereof by a fault it repeatedly scans the region of the fault and only operates alarm or control means when the detector has been actuated a predetermined number of times. The detector head 10 is carried by a carriage 5 driven by a motor M to scan the fabric F. Limit switches MS1,MS2 reverse the direction of the scan at the extremities of the fabric. The detector head comprises two lamps and a block of four germanium or cadmium selenide cells responsive to changes in reflectivity of the fabric. The detector circuit comprises a first thyratron which fires on detection of a fault to actuate a relay. The relay then reverses motor M, cuts off the thyratron, renders the detector insensitive and feeds a pulse to a count condenser. The relay de-energizes after a time set by an R-C circuit to resume scanning with a sensitive detector. The sequence is repeated each time the fault is detected until the voltage on the count condenser is sufficient for a second thyratron to fire to light a warning lamp and/or stop the knitting machine. If the fault clears before this happens, a further relay de-energizes to discharge the count condenser. The detector is rendered insensitive on starting to permit a repaired fault to clear.
