Patent GB-652389-A (GB)
Abstract: 652,389. Calculating-apparatus. AKTIEBOLAGET FACIT. Dec. 22, 1947, No. 33842. Convention date, Nov. 6, 1946. [Class 106 (i)] A calculating machine of the cam-disc and pin-wheel type having a full-stroke mechanism, which is operative when the actuator is engaged with totalizer wheels and comprises a toothed disc having a recess and co-operating with a pawl, and a clearing bar adapted to be moved into the paths of the setting tabs or the like so that the actuator may be cleared by rotating the crank through about a quarter-revolution, is characterised in that on at least one side of the recess and within a sector corresponding to that part of the revolution, the teeth of the toothed disc have locking surfaces acting in one direction only, while the other teeth act in both directions. The pin-wheels 1 are splined and axially clamped on a shaft 11, Fig. 11, connected by gears 36, 43, Fig. 2, to a shaft 42 having a crank on which is slidably mounted a handle 50. When the handle is released in its home position, a sprung plunger 52 moves a rod 56, slidable in the machine frame and carrying a plate 57, to the left and the plate 57 shifts a notched bar 33, which otherwise locks each cam-disc 15 to its corresponding pin-wheel 1, to enable the camdiscs to be differentially set. A pawl member 44 (see also Fig. 8) on the shaft 42 is frictionally coupled to the gear 43 by a conical spring and co-operates with a toothed disc 38 fast on the shaft 11, projections 44a, 44b on the member 44 being held against a fixed stud 47 in adding and subtraction operations respectively. During the first quarter of a cycle, the pawl 44c on the member 44 co-operates with asymmetrical teeth 38b so that if the drive is in an adding direction (shown by the arrows) a reversal is possible during that part of the cycle and a complete cycle is unnecessary when clearing the differentially-set cam-discs as described below. If the drive is in the subtraction direction, the pawl 44c co-operates with steep faces of the teeth 38b to prevent a reversal. After a quarter of a cycle, when the actuators are engaged with the totalizer wheels (not shown), normal symmetrical teeth 38a cooperate with the pawl 44c to prevent a reversal of the drive in either case. To clear the camdiscs, the plate 57 is held to the left by a knob 60 fixed in the rod 56 and the handle is given a quarter turn in the adding direction. As soon as the actuators rotate, a notch in a disc 37  fast on the shaft 11 moves out of alignment with a projection of the plate 57 so that the latter is held to the left by the disc 37 even though the knob 60 is released. A bar 61, Fig. 4, engaged by the plate 57, is thus also held to the left so that projections 61a thereon are moved into the paths of setting tabs 25 on the cam-discs 15. When the latter have been restored, the operating handle is reversed and returned to its home positions.
Patent GB-762003-A (GB)
IPC: G06C23/02
Abstract: 762,003. Switches held set and freed mechanically. FELT & TARRANT MANUFACTURING CO. Jan. 18,1954, No. 1474/54. Class 38(5) [Also in Group XIX] Mechanism for automatically switching on and off the driving motor of a keyboard controlled machine comprises a latch normally holding a switch-opening member effective against the action of a spring, a link pivotally connected to the latch, connections from the keys and other manually operable members to move the link and trip the latch to close the switch, and means operated in timed relation to the operation of the motor for returning the switch-opening member to open the switch. In the mechanism shown, a calculating-machine driving motor circuit is controlled by switch contacts 234, 235 which are normally held open by means of a slide bar 226; a spring-actuated lever 246 urges the bar to the left to release the contacts, but a pawl 222 normally engages ratchet teeth on the bar so that this movement is prevented and the switch contacts are, as shown, held open. The pawl 222 is mounted on a lever 224 connected to a link 205 which is urged to the left by a spring 212, so maintaining engagement of the pawl. The link 205 pivotally supports a bell-crank 203 and is formed with a shoulder 276. Upon actuation of an accumulator zeroizing handle 71, a lever 153, forming part of known mechanism for detraining the accumulator, is rocked counter-clockwise and a tooth 201 thereon engages the bell-crank 203 to thrust the link 205 to the right so disengaging the pawl 222 and allowing the switch contacts to close. Immediately thereafter the bell-crank 207 is tripped by a fixed stud 209 and is released from the tooth of lever 153, so that the pawl 222 reengages the bar 226 even though the zeroizing handle is held in its forward position. Associated with each ordinal column of the amount keys is an upstanding arm (not shown) on a transordinal shaft 267 which also carries an arm 271 linked to lever 273 bearing stud 275. Depression of an amount key results in counterclockwise. movement of arm 271 and with it the lever 273, the stud 275 moving the link to the right, again resulting in disengagement of the pawl 222 and closure of the switch contacts. Restoration of the bar 226 to reopen the switch contacts, after a period following the last actuation of an amount key or the zeroizing handle, is by a spring-actuated lever 251 bearing a pawl 255 engageable with rack teeth (two) 257 on the bar 226. A bevel ended lug 258 on the lever 251 is adapted to be engaged by pairs of driving rollers 259, 260 on a wheel 261 driven from the machine shaft 45 through a reduction train. Each pair of rollers oscillates the lever 251 causing the pawl 255 to restore the bar 226 rearwardly by one tooth so that the switch contacts are re-opened after a period (one revolution of wheel 261), provided the zeroizing handle 71 or an amount key is not actuated and the pawl 222 thereby tripped. Specifications 154,603. [Class 106(iii), 341,435, 344,868 and 566,376 [all in Group XIX], are referred to.

Title: Pipe-line inspection apparatus
IPC: G01N29/265
Filed: 1979-06-08
Abstract: A pipe-line "inspection pig" consists of a drive unit 11 adapted to move through the pipe-line under the influence of fluid flowing in the pipe-line, a test-sensor carrier 12 and an instrumentation carrier 13 towed by the drive unit. The test sensors may be ultrasonic probes 16 arranged in circular array on a support 18 preferably rotatably mounted on a carrier body co-axially with the pipe-line axis. The ultrasonic probes are arranged within respective wheels which run on the pipe-line wall along mutually parallel paths which may define a helical configuration dependent upon the oblique setting of the axes of the wheels with respect to the pipe-line axis. Instrumentation (Fig. 2, not shown) monitors and records rotational and axial displacement through the pipe-line and relates this information to recorded probe signal data. The plurality of ultrasonic probes in circular array in conjunction with the proposed helical configuration of their paths permits the recording of a greater quantity of test information than is available with previous proposals. The provision of an opening in a drive surface of the drive unit allows sustaining of fluid flow in the pipe-line in the event of the inspection pig jamming in the pipe-line. In one embodiment (Figs. 4, 5 not shown), radially retractable test- sensor-carrying segments operate to retract automatically after a present time delay in the event of jamming in the pipe-line. <IMAGE>
