Filed: 1972-06-05
Abstract: 1365731 Conveyers CHARCON PRODUCTS Ltd 5 June 1972 [5 March 1971] 6117/71 Heading B8A A pallet 11 carrying spaced slabs 12 is moved on a roller conveyer 6 towards a slab cradle 21 of a traversing carriage 17, the cradle serving to move the slabs into abutting relationship on a preceding pallet located beneath the cradle. The pallets are moved stepwise along the conveyer by a chain having dogs 10 and the carriage 17 is reciprocable along the length of the centre pallet by a pneumatic ram 15. Movement of the carriage causes the cradle 21 to pivot from the intermediate horizontal position shown to a vertical position at the ends of travel of the carriage. The cradle includes pneumatically actuated fingers 31 for gripping a slab. In operation, the carriage 17 having been moved to the left, the fingers 31 of the now vertical cradle 21 are engaged with the leading slab on the pallet 11 and the slab, by movement of the carriage to the right, is deposited in the shown (broken line) position. Momentary disengagement of the fingers 31 when the slab is horizontal allows the slab to be fully seated in the cradle 21. As the carriage is returned towards the pallet 11, the latter is indexed to bring the second slab into position, ready for engagement by the cradle 21. This slab having been placed in abutment with the first slab, the carriage and conveyer dogs 10 operate as before for the remaining slabs. Automatic actuation is controlled by limit switches 40, 41. In Figs. 4-7 (not shown) the traversing carriage (52) and support means co-operate to provide a small angle of inclination of the slabs. While the slabs are horizontal they may be inspected or subjected to water sprays and rotary brushes, the period during which the slabs are horizontal being extended accordingly. At the ends of its travel, the carriage may move more slowly than during the remainder of its movement.

Title: Improvements relating to railway signalling apparatus
IPC: B61L3/04
Filed: 1922-10-13
Abstract: 209,164. Neville, W., Bryant, T., and Bryant, R. R. B. Oct. 13, 1922. Track apparatus actuating signals on, and other than on trains, and for stopping trains; recording signals and indicating and recording movements of trains.-Apparatus for signalling on and ior stopping trains is provided at different points in the length of the trains and coacts with ramps a distance apart, on the track so as to effect indirectly a record of the observance of the signals. Ramps 5, 6, Fig. 2, are placed between thirty and fifty yards, and between three and four hundred yards respectively in advance of a stop signal and are pivoted so as to be raised by connection with the signal wire, or by a separate lever, which when operated to raise the ramps, allows the signal lever to be moved to the danger position. The engine apparatus consists of a shoe 9, Fig. 4, adapted to rise on contact with a track-ramp and to operate a visual signal 23, an audible signal 43, a steam-throttle 35, a brake-valve 36, and a counter 21. A counter 28, an audible signal and a visual signal 29 in the guard's van are also operated by a similar shoe. On passing the ramp 6 in the danger position, the shoes 9 are raised causing both counters to move one step. If the signal is at danger, the train is brought to rest with the engine shoe on the ramp 5 so that the engine counter moves a second step and the driver receives a signal in the cab, by the lowering of the ramp, when the road is clear. The train proceeds, but the counter 28 in the guard's van is not operated on passing the ramp 5 so that it shows one step less than the counter 21 on the engine, forming a record of the operation of the apparatus and the observance of the signals. If both ramps are passed in the danger position, both counters move an equal number of steps. A counter 31, Fig. 3, in series with a bell 32 and a battery 33 is connected to the ramps and rails so that each time a shoe contacts with a ramp, the counter and bell are operated. Clocks may be used to record the time of operation of the counters. The power circuit of electric trains may be controlled by the shoes.

Title: Improvements in methods of recording and reproducing discontinuous signals
Inventor: NUTTALL THOMAS CAYTON
IPC: H04N5/84
Filed: 1957-02-27
Abstract: 857,582. Automatic alignment control systems. RANK CINTEL Ltd. Feb. 27, 1958 [Feb. 27, 1957], No. 6590/57. Class 38 (4). In a system for automatically aligning a scan with linear traces of a discontinuous signal record, unmodulated traces provided prior to the commencement of each element of the record are explored by displacing the scan in a transverse direction to produce a signal, indicative of the mean position of the scan, which is used to correct the relative position of scan and record. In Fig. 2 television signals are recorded line-byline on a cinematograph film 3, spot-wobbling producing picture signal traces 4. In recording, the spot-wobble oscillation is eliminated between lines by the blanking pulses and the flyback of the line scanning generator is arranged to terminate before the end of the television signal blanking period so that locally - produced brightening-pulses produce unmodulated portions 5 without spot-wobble, at the commencement of each line to mark the centre lines of the picture signal traces. During reproduction, a light spot scanning the lines is oscillated between positions 7, 7<SP>1</SP>, Fig. 3, while traversing the unmodulated portion 5 so that if the mean position of the spot corresponds to the centre line of the picture signal trace 4, equal signals are produced at positions 7, 7<SP>1</SP>. Any equality in these signals is utilized to correct the relative position of spot and trace automatically as shown in Fig. 6, in which the recorded cinematograph film 25 is scanned by a cathode-ray tube 29 controlled by a line-scan generator 31 synchronized by signals applied at terminal 32. The signals produced from the film by a photo-cell 34 are applied through an amplifier 35 and black-level clamp 36 and are available for external use at terminal 38. A vertical scan generator 39 which produces the oscillation of the spot while traversing the unmodulated portions of the trace is synchronized by applying at terminal 40 pulses which are appropriately timed relatively to those applied at terminal 32. Pulses are also derived from scan generator 39 by a pulse generator 42 when the spot is in each of its extreme positions relative to the unmodulated portion and these pulses are applied to a sampler 43 which is fed with video signals from clamp circuit 36 and produces in a generator 44 a signal indicative of any inequality in the signals at the two positions. From this error signal a filter circuit 45 derives low-frequency components which are applied to a control circuit 46 to correct the mean speed of film drive mechanism 28, and high-frequency components which are applied to a deflection generator 47 to correct the vertical position of the spot.

Abstract: 726,096. Screw-cutting lathes. CRI-DAN. March 10, 1953 [Jan. 13, 1953], No. 6604/53. Class 83 (3). A screw-cutting lathe comprises a pitch cam 10 for reciprocating the tool carriage 5 longitudinally on a transverse carriage 4, the cam being adapted for mounting and rotation in opposite ways so that the tool may be positively traversed to cut in either direction. The carriage 5 carries a roller 9 engaging the cam 10, which is secured by screws 20 to the cam-shaft 8 in either of the positions shown in Figs. 2 and 8. In each case the length (A+B), and the limits, of travel of the carriage are the same. The roller and cam are held in contact by a spring whose action is reversed by manually-positioned retaining pins engaging spring-abutment members or by a reversible pressure-fluid piston. In the latter case, the fluid-connections are automatically reversed by a valve 43, Fig. 8, which, when the cam 10 is reversed, is moved to its left-hand position against a spring 51, a roller 50 on the valve-stem then abutting the rear face of the cam.

Abstract: 233,486. Dawson, Payne, & Elliott, Ltd., and Stott, E. March 15, 1924. Cylinder machines; gripper mechanism.-An underfed single or two-colour stop-cylinder machine is arranged to take sheets fed to gauges on a stationary table T, the cylinder being rotated for nearly a whole revolution during the forward motion of the bed, and having its rotation completed during the backward movement of the bed. The grippers l on the cylinder bare controlled by a cam r, which is freely mounted on the impression cylinder and is stationary for the greater part of the movement of cylinder b. The cam r is adapted to act on a bowl o on a spring-pressed lever fitted with a gear sector n geared to the gripper shaft m, the grippers being closed by spring action when the bowl o is adjacent the low part of cam r. During the printing-stroke a raised part of the cam r opens the grippers to permit of delivery, and while the grippers are passing the feed board they are rotated counterclockwise into a recess in the cylinder so as to clear the table T and the registering- gauges. The grippers are finally closed upon the sheet while the rotation of the cylinder is completed, the cam r being moved clockwise by a cam-and-link mechanism to permit of this gripper movement. The final movement of the cylinder is effected by a pawl' d on an oscillating lever c operated by a link h and a cam. The pawl d acts on a projection e on a brake disc on the cylinder shaft, and to prevent the cylinder from being rotated too far, a lever g engages the front of projection e ; this lever is operated by a cam to check the movement of the cylinder b and ensure its stopping in the correct position,
