IPC: G05B19/23
Filed: 1955-11-22
Abstract: 834,406. Electric selective signalling systems. IGRANIC ELECTRIC CO. Ltd. Feb. 22, 1957 [Nov. 22, 1955], No. 33422/55. Class 40 (1). [Also in Groups XIX and XL (b)] An electric positional control apparatus comprises driving means (motor 11, Fig. 1) for moving a movable member 10, means 12 for deriving electric pulses in accordance with the movement of said member, means for detecting the direction of movement of said member, an impulse counter 13 arranged to vary the count therein in one sense in response to movement in one direction of said member and to vary the count in the opposite sense in response to movement in the other direction and means for controlling said driving means in accordance with the count in said counter, the speed of said driving means being reduced as said member approaches a predetermined position. As described, movement of the movable member 10, which could be part of a machine tool, produces pulses photo-electrically which count down a pre-set counter (see Group XIX), the lowest three denominations of which sequentially switch shunting resistors into the power circuit of the motor as they reach zero until finally the movable member crawls to rest when the counter reaches zero. Two photo-electric cells sensing two beams of light which pass through a fixed and a movable diffraction grating produce pulses as the member moves, the gratings being arranged so that each line on one crosses one on the other (that is, the lines are just not parallel) whereby the pulse trains produced by the photoelectric cells are out of phase with each other, the phase difference being indicative of the direction of movement of the member. As a result of this phase difference pulses are applied to one lead, by a conventional logical phase discriminator, if the member is moving forwards or to a second lead if it is moving backwards.

Abstract: 759,732. Digital electric calculating-apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 19, 1954 [Nov. 23, 1953], No. 33545/54. Class 106 (1). An electronic commutator comprises a source of pulses, a ring of trigger elements advanced under control of said pulses, a chain of trigger elements advanced under control of said ring of trigger elements, means for suspending the advancement of said ring of trigger elements, and means for directly advancing said chain of trigger elements under control of said source of pulses. In an electronic computer of the type described in Specification 673,759 which is referred to and of which the present invention is a modification, multivibrator produced clock pulses-" A " pulses-pass two " and " gates 326, 322, to a lead 175, to sequentially step an " on " condition around a Primary Timer ring consisting of twenty-three triggers labelled " step 1 ", " step 2 ", " step 3 " ... step 23 " which controls the timing of all operations in the computer, and which, each time its step 2 " is " on ", opens a gate 239 to allow a " B " pulse-an inverted " A " pulse-to pass to a programme advance lead 65 to step an " on " condition in an open Programme Ring consisting 12, 13 ... 31. Associated with each stage of the Programme Ring is a set of three sockets or hubs, only those for stages 1, 10, 14 and 20 being shown, the voltage on which depends upon the state of the associated trigger, and to which are plugged, in any desired sequence, leads for controlling various computer functions. In order to cause the Programme Ring to advance a number of stages without waiting for the Primary Timer to complete the same number of cycles, say from stage 10 to stage 14, programme hub 10 is connected to a skip-on hub 333 and programme hub 14 to a skip-off hub 338, then when stage 10 of the Programme Ring goes " on ", at which time " step 2 " of the Primary Timer will be " on ", it causes a skip trigger 324 to go " on " thus closing the gate 322 and stopping the flow of " A " clock pulses to the Primary Timer. Thus " step 2 " of the Primary Timer remains on " keeping gate 239 open so that a succession of " B " clock pulses pass to the Programme Ring. When stage 14 goes " on "- it puts " off " the skip trigger 323, opening the gates 322, and allowing the " A " clock pulses through to step the Primary Timer.

Title: Improvements in or relating to fluid pressure operated devices
IPC: F15C4/00
Filed: 1962-09-05
Abstract: 1,011,632. Pressure gauges. BAILEY METER CO. Sept. 5,1962 [Sept. 11,1961], No. 34089/62. Heading G1L. In a pneumatic pressure transmitting device having a pivotally mounted force beam a Bourdon tube responsive to pressure displaces the lever for establishing an output signal and means responsive to the output signal apply a restoring force to the beam. In the arrangement shown in Fig. 1 the pressure of fluid in a conduit 10 is transmitted through a pipe 12 to a pneumatic pressure transmitting device 14 which establishes a proportional pneumatic signal pressure in a pipe 16 which pipe 16 is connected to a manual-automatic selector station 18 in which the signal pressure is compared with a set point signal to establish a difference or error signal. The output of the selector station 18 is supplied to a pneumatically operated valve 22 which controls the fluid flow in pipe 24. A recording instrument 26 is responsive to the pressure in pipe 16 to provide a continuous record of the fluid pressure in conduit 10. The pneumatic pressure transmitting device 14 operates as follows. Any increase in pressure in conduit 10 will tend to uncoil a Bourdon tube 46 to apply a force to pivot, in a clockwise direction, the lower end of a beam 48, secured intermediate its ends to a resilient diaphram 52. As a result of this movement a baffle 64, secured to the upper end of the beam 48, is moved closer to a nozzle 68 to cause an increase in fluid pressure therein thus causing operation of a reset amplifier 62 to increase the signal pressure in pipe 16 and a pipe 92. The resulting pressure increase in pipe 92 expands a bellows 88 to expand a restoring force, through a beam 76 and a vertically adjustable fulcrum 86, on the upper end of the beam 48 to restore the beam 48 to its original position. When the beam 48 is restored to its original position the spacing between the baffle 64 and nozzle 68 reverts to normal and the amplifier 62 will stabilize at the higher output signal pressure condition. If a decrease in pressure in pipe 10 occurs a similar opposite sequence of operations will occur and the amplifier 62 will be stabilized at the lower output signal condition. Movement of the beam 48 is limited by stops 150, 154. A calibrating spring 94 is mounted between the end of the pivotal beam 76 and a supporting wall 58. An adjustable stabilizing spring 96, mounted between a bracket 98 fixed to the beam 48 and a supporting plate 90, is provided to appose the force applied to the beam 48 by the Bourdon tube 46. Specifications 892,056 and 931,743 are referred to.

Abstract: 605,235. Driving auxiliary mechanism on tractors. FORD MOTOR CO., Ltd. Dec. 18, 1945, No. 34317. Convention date, Dec. 29, 1944. [Class 79 (ii)] A safety device for a tractor having a power take-off shaft comprises a main hood which normally shields the take-off shaft but which can be swung clear of the shaft whereupon a secondary hood, normally clear of the shaft, is moved automatically to shield the shaft. As shown, a power take-off shaft 12 protrudes from the rear end of a tractor 10 and is enclosed for safety reasons by a large hood 15 having a flared portion 16 and vertical side members 18. The hood is pivotally mounted on the tractor by bolts 19 and is supported in the position shown by a pin 22 passing through aligned apertures in the hood and tractor frame. Mounted also on the tractor frame and within the hood itself is a second hood 24 mounted by a pair of brackets 29, 30. This second hood is maintained in the position shown, by a pair of tongues 32 secured to the inside of the first hood, whilst the power take-off is in use. The second hood may be spring urged into a position in which it encloses the shaft. When it becomes necessary to use the pulley 14 which provides a second power take-off device, the main hood, which obstructs the pulley, is lowered by withdrawing the pin 22 but the shaft 12 is then enclosed by the smaller hood, the two hoods taking up the positions shown dotted in Fig. 1.
