Title: Roll changing mechanism for rolling mills
Inventor: REMNER ROBERT ANDREW
IPC: B21B31/10
Filed: 1967-06-20
Abstract: 1,131,790. Rolling tubes. BLAW-KNOX CO. 20 June, 1967 ;[17 Aug., 1966], No. 28425/67. Addition to 960,200. Heading B3M. In a tube or rod rolling machine of the kind described in Specification 960,200, in which a saddle 10 carrying grooved working rolls 13 and 14 and backing rolls 17 and 18 is reciprocated by a crank mechanism D, the rolls are arranged to be removable as a unit transversely from the machine using a conveyer G. Before removal of the rolls, the saddle 10 is positioned centrally relative to the housing of the machine and wedges 61 and 62, which are located between reciprocable wedges 23 and 24 and the housing, are moved outwardly. This causes thrust plates 19 and 20, which carry racks 114 and 117 normally engaging with pinions on the rolls to rotate the rolls during reciprocation of the saddle, to move away from the rolls, the upper thrust plate by springs 53 and the lower one by gravity. Rollers 124 and 125, Fig. 10, now support the chocks 103 of the roll 14 on rails 113 extending between the side plates 100 and 101 of the saddle. Vertical rods 110 which pass through the working roll chocks 102 and 103 tie the chocks together, whilst bolts 128 serve to maintain the backing roll chocks 106 and 107 in place. The rods normally contact the rails 113 and serve to balance the chocks 102 by means of helical springs 108. Finally, retaining plates 105 are loosened and moved aside to permit movement of the roll assembly relative to the saddle side plates. A chain driven conveyer 163, Fig. 7, whose upper surface forms a continuation of the rails 113, receives the assembly, while a further conveyer 162, simultaneously if desired, brings a replacement assembly to the machine.

Title: Improvements in or relating to brakes for vehicles
IPC: F16D55/14
Filed: 1945-10-27
Abstract: 599,541. Disc brakes. ROBERTS, G. P. Oct. 27,.1945, No. 28459. [Class 103 (i)] A disc brake comprises a pair of friction rings arranged to be given a part rotation in opposite directions to cause them to be moved apart by balls in conical recesses or other means, to engage annular friction surfaces secured to the 'member to be braked. Certain of the conically recessed members may be adjustable automatically or manually to take up wear of the friction surfaces. A pair of channel-section rings 10, 11 are rotatably mounted on a cylindrical member 14 secured to the axle assembly of a vehicle wheel and carry friction linings 15 for engagement with a two-part casing 29, 30 which may be bolted to the wheel or may be extended radially to receive a detachable wheel rim. The rings 10, 11 are urged towards each other by wire springs and carry conically-recessed members 17, 18 that receive balls 16. The rings can be turned in opposite directions to cause the balls to move them apart by tappets 21, 22 that engage abutments 25, 26 on the respective rings and are moved by a wedge 23 and interposed balls 31. The stem 32 of the wedge has a ball-andsocket attachment 33 to a plunger 34 slidable in a socket 35 on the back-plate 36 and actuated by a cable 37 or a rod 40. The tappets are urged towards each other by a spring 24. When the rings 10, 11 contact the rotating casing the frictional torque causes one or other ring, according to the direction of rotation, to engage a stop and the other ring to turn further, thus giving a self-energising action. The plunger and socket 34, 35 may be replaced by a similarly arranged hydraulic cylinder, the piston acting however to push the wedge or a radially arranged lever pivoted at its middle point on the back plate may be connected at its ends to the stem of the wedge and a pull-rod. The wedge may be operable both hydraulically by a pedal-operated master cylinder and mechanically by a hand lever or a wedge and tappets 21, 22 may be arranged at diametrically opposite positions on the brake the wedges being respectively operated hydraulically by a pedal and mechanically by a hand lever. To take up wear of the friction surfaces one of the rotating surfaces may be adjustable manually towards the other by screw means or as shown the members 18 may screw into sleeves 19 on the ring 11 and be toothed to mesh with a toothed ring 51 which may be turned manually as by rotating one of the members 18 or automatically by a pawl 53 pivoted on one of the rings 10, 11 and abutting on a stop 54 on the other ring. The pawl engages ratchet teeth 52 on the ring 51 and if in an application of the brake the relative rotation of the rings 10, 11 is excessive, the pawl slips a ratchet tooth and the ring 51 is advanced during the return movement of the rings 10, 11. The normal position of the pawl is determined by a stop 56.

Title: Improvements relating to apparatus for the selective location of data frames recorded on film
Inventor: SHEARD JOHN RAYMOND
IPC: G06K17/00
Filed: 1956-09-21
Abstract: 869,622. Electric selective systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. Sept. 23, 1957 [Sept. 21, 1956], No. 28861/56. Class 40 (1). Apparatus for selecting a desired one of a numbered series of frames carried on a film 1 comprises a film-feeding mechanism, an electromagnetic head 4 sensing code signals in a marginal track 2 which identify the individual frames, means for registering the number of a desired frame, means for comparing the signals sensed with the registered number and means for stopping the film feed when they are the same. The signals picked up by head 4 pass through an amplifier 6 to a first digit indicator 7 and a digit gate 8. The indicator 7 initiates a pulse counting device 9 and a gate signal generator 10 providing signals for the gate 8. The generator 10 is coupled to the pulse counter 9 so that a gate pulse is inhibited at the end of every binary word. Signals passing through gate 8 are applied to a comparator 11 into which the desired number is entered by a keyboard 12. This number may be entered into a static register, the digits being read out serially and compared in non-equivalence gates with the sensed number sent in through gate 8. It is necessary to provide for movement of the tape in either direction and desired number set up on key-board 12 is therefore stored in two registers in opposite order and read out for comparison from one or the other. Three outputs from the comparator 11 are connected to three relayoperating units 13, 14, 15, unit 14 being connected to the other two so that when it has an input, it prevents their actuation. The units 13 and 15 are operated if the sensed number is larger and smaller, respectively than the number set up on the keyboard and unit 14 operates when they are equal. If units 13 or 15 are actuated they cause the servomotor 16 to be driven at a high speed in one direction or the other, as required. The input to unit 14 is connected via an amplifier 20 to drive the motor 16 at a slow speed until a registering signal is transmitted from a photo-cell 5 due to light passing through a transparent square 3. A square 3 associated with each frame is so placed that when it registers with cell 5 the frame is in the correct position for viewing, e.g. by projection. The signal from cell 5 inhibits gate 19 and the motor stops. The frames may carry the images of complete documents or they may carry digital data in which case, after being selected and brought to viewing position they may be scanned systematically and the data signals produced fed to a computer.

Title: Machine memory
IPC: G06F9/34
Filed: 1973-06-18
Abstract: 1438517 Data processing system HONEYWELL INFORMATION SYSTEMS Inc 18 June 1973 [20 June 1972] 28890/73 Heading G4A The system comprises a stack memory which is addressable in three modes. In a stack mode (1) data is stored on a last-in-first-out basis. In an absolute index mode (2) an absolute address is accessed, and in a relative index mode (3) an address that lies a selected distance from the top-most data-containing location in the stack is accessed. Numbers of double length are accessible. 'The system includes a stack pointer 12, e.g. a counter, which points to the top-most location containing data in the stack memory 10. The pointer is incremented or decremented during each read and write cycle of mode 1. For a single-word mode 1 write cycle the pointer is decremented by 1 (assuming the lowest location in the stack has the highest address number). The pointer then passes via a register 14 and an adder 20 to address the top-most free location in stack 10. It is also stored in Y-register 21. The word to be written passes from a A- register in unit 24, via register 14, to the stack. In a single-word mode 1 read cycle, the pointer passes via 14 and 20 to Y-register 21. It addresses the top-most word in the stack, and this word is read out via 14 to the A register. The pointer is then incremented by 1 so as to point to the new top-most word. In a double-word mode 1 write cycle the pointer is decremented and placed in the Y- register as before, but in this case the least significant word of the two is read from the B- register and passes to the top of the stack via register 14. The contents of both the stack pointer 12 and the Y-register 21 are now decremented by 1. The stack is addressed by the new content of the Y-register and the most significant word is read from the A-register to that address. In the double-word mode 1 read cycle it is necessary to read the least significant word first and therefore to increment the stack pointer by 1. The pointer passes to the Y-register and causes read-out of the word to the B-register. Now the pointer is incremented again so that it points to the word written-in prior to the least significant word, but the content of the Y-register is decremented so that the most significant word is accessed and passed to the A-register. In the absolute index mode an address is passed from register 28 via the adder 20 to address the stack. However, in the relative index mode the relative address from register 14 is added to the pointer from stack pointer 12, the sum address being used to access the stack. The relative address may be received from the memory 10 or elsewhere.

Inking-apparatus.-Apparatus for decorating ceramic or other ware, e.g. plates or saucers, comprises a stationary former whose surface corresponds approximately to the contour of the articles to be decorated, a flexible, e.g. rubber, band arranged to travel across the former and coated with the liquid decorating medium, and a pad bearing the design and arranged to move so as to press the band against the former so that the surface of the pad is evenly coated with the liquid and the pad is ready to move into contact with an article and impress the design upon it. The band 13 runs on rollers 11, 12 mounted in a frame 10 supported on a shaft 8 and on springs 59, the roller 11 being driven from a gear box 23 through a chain 22, sprocket 19 and chain 15. The chain 22 also drives an inking roller on a shaft 27, which roller transfers liquid from a container 29 to the band. The pad 40 is mounted on a bracket 43 slidably mounted on a shaft 44, being vertically adjustable by rotation. When a lever 47 is depressed, the bracket 43 is lowered and the pad 40 forces the belt 13 against the former 35. The shaft 44 is then rotated through 90 degrees by means of the lever 47, to bring the pad into decorating position. When the pad is in inking position, a scriber on a horizontal arm attached to the shaft 44 engages a striker on a shaft 21 to rotate a block 20 and disengage the sprocket 19 from the chain 22 to stop the movement of the band, and a cam on the rod 44 depresses a lever against an abutment on the frame 10 to swing the frame against the springs 59 and move the band out of contact with the inking roller. When the pad is moved to decorating position, a spring restores the block 20. The band is tensioned by screens 31 adjusting the roller 12.
