Title: Improvements in pistons
IPC: F02F3/10
Filed: 1932-06-18
Abstract: 403,390. Pistons. OUBRIDGE, W. A., Parklands, Park Road, Coventry. June 18, 1932, No. 17263. [Class 122 (i).] A bi-metal piston comprises a part a of castiron or steel provided with gudgeon pin bosses a<2> ; the body b of aluminium or aluminium alloy is cast around the part a, and is provided with bosses bl which enclose the bosses a<2> and extend inwardly of them ; the gudgeon pin thus keys the two parts together. The piston ring grooves may be formed in the part b or in the part a which does not then extend to the bottom of the skirt. The portion a may be formed with projections or recesses so that when the other part is cast on it metal will flow in or around them, so locking the parts firmly together. Additionally or alternatively, a corrugated ring c of steel may be introduced between the parts a, b, to take up the clearance which occurs due to the different coefficients of expansion of the two parts.

Title: Improved apparatus for mining
IPC: E21C27/14
Filed: 1942-12-04
Abstract: 565,342. Mining-machines. MAVOR & COULSON, Ltd., and MAVOR, J. B. Dec. 4, 1942, Nos. 17263/42, 5376/43, 9189/43 and 16783/43. [Class 68 (i)] A mining-machine comprises a wedge-like splitting head and a single endless cutter-chain moving bodily with, but in advance of, the head to make a vertical incision in the coal, the leading part of the head being located within the circuit of the cutter-chain so as to enter the incision, the head then splitting the coal from the seam. As shown, the wedge head A, with superposed prongs 17, rests on the mine floor and carries the chain-type shearing cutter F ; the head A is secured to the cylinders 3, 4 of a coaxial hydraulic ram arrangement including pistons 5, 12 secured respectively to pairs of hydraulic jacks E, D, provided with pivoted sprags 14 to engage the floor. In use, the pairs of jacks E, D are operated alternately to jam them between the roof and floor, and the coaxial rams are operated alternately to advance the wedge head, shearing cutter and inactive pair of jacks. As the coal breaks down, a scoop 18 on the wedge head discharges it laterally on to a conveyer M. The first Provisional Specification describes a form of machine in which three superposed hydraulic rams each carry a wedge head, the central head, which may lead the other, being of spear form and the other heads having a single oblique cutting edge ; a single vertical jack provides an abutment. The second Provisional Specification describes a form in which a screw or hydraulically-operated toggle provides an abutment, and the third Provisional Specification a. form in which a cutter disc replaces the cutterchain.

Title: Buffer memory system
IPC: G06F5/06
Filed: 1973-04-10
Abstract: 1418986 Buffer memory systems LITTON INDUSTRIES Inc 10 April 1973 [10 April 1972 5 March 1973] 17273/73 Heading G4C A counter 32 (Fig. 2) is incremented whenever a word is written into a buffer memory 22 from a computer memory 13 and a counter 30 is incremented each time a stored word is read out, for example for display by a generator 18, so that the count in the counters represents the current status of words stored in the memory. Read out may occur at a slower rate than write in. As described select logic circuitry 16 in a console 15 generates a write request whenever data intended for the console is fed from the computer, control circuitry 42 incrementing both counter 32 and a reversible counter 44 for each word read in. The counter 32 supplies the "write" address for the memory. Read request signals from display generator 18 result in counter 30 being incremented to provide the "read" address for the memory, counter 44 being simultaneously decremented. Counter 44 consequently holds a count of the number of words stored in the buffer memory. Whenever the memory is either full or empty a signal is fed to inhibit circuitry 54 to inhibit either the computer memory 13 feeding data or display generator 18 requesting data. The memory 22 may be either a core store or a micro circuit memory. Display generator 18 may be either a teletypewriter or a CRT. The difference in count between counters 30, 32 may be used to derive the memory full and memory empty signals.

Abstract: 172,346. Jackson, W. J. Mellersh-, (Soc. Anon. d'Horlogerie et Bijouterie de Geneve). June 29, 1920. Dials.-Relates to clocks and watches of the kind in which a movable dial carrying chronometric indications rotates always in the same direction under a fixed dial concentric with a movable pointer, the rotation being performed by steps by a force derived from the mainspring and intermittently released to change the indication of the rotating dial appearing at a window in the fixed dial. According to the invention, the movable dial is concentric with the fixed dial and is provided with a set of teeth or like projections engaged by an operating member operated by a toothed sector alternately engaged and released by the cannon pinion. In the form shown in Figs. 3 and 4, two concentric movable dials b<1>, b<2> are used interconnected by a pinion d, the dial b<1> being marked with hour indications 1 to 24 and the dial b<2> with hour indications 1 to 12 appearing respectively at windows a', a<2> in the fixed dial a. The dials b<1>, b<2> are moved step by step by means of a pawl e' carried by a toothed sector e, which is moved in one direction against the action of a spring f by the cannon pinion i until released by a cut-away portion of the pinion, this operation being repeated every hour. A pawl h prevents backward rotation of the dials. The dial b<1> is mounted between rollers c, one of which may be pressed inwardly by a spring. The marks on the dials may indicate dates of the month, days of the week, weeks, months, seasons, years phases of the moon and so on. Various modifications of the arrangement of the dials and of the manner in which the sector is driven and operates are described.
