Abstract: 1463927 Double piston pneumatic hammer drills INST GOR DELA SIBIR OTDEL AKAD NAUK SSSR 8 July 1975 28666/75 Heading B4C [Also in Division B3] A pneumatic hammer drill has two pistons 2, 3 with a helical screw arrangement 4 connecting them, a one way clutch 10, chambers 12, 13, 14 in a housing 1, a rotatable chuck 5 and an air distribution system 15. In operation the pistons 2, 3 move towards and away from each other as the pressure in chamber 13 exceeds that in chambers 12, 14 or vice versa. As the pistons 2, 3 move away from each other rotation of cylinder 3 is produced by the screw 4 and is transmitted to the drill by chuck 5. As the pistons move in the opposite direction the clutch 10 allows piston 2 to rotate and the drill therefore does not rotate. Impact of piston 3 on tool holder 7 causes the hammer action of the drill. Several modifications are described and in some of these the one-way clutch is located between the pistons and limiting abutments are provided which prevent excess movement of one piston relative to the other.

Title: Electronic railway equipment
IPC: B61L25/04
Filed: 1962-07-26
Abstract: 1,019,366. Signalling systems. STAMICARBON N.V. July 26, 1962 [July 27, 1961], No. 28822/62. Heading B7N. In a railway signalling control system, particularly for mines in which a loop aerial is positioned adjacent the tracks of each junction and an announcement aerial is positioned adjacent each entry section to the junction and in which each train is provided with means for transmitting a signal to an adjacent aerial indicative of its type e.g. full or empty, the visual signals controlling each entry to the junction are controlled by the presence of a train at the associated announcement aerial, its type and the presence of other trains at other entry sections to the junction or on the junction. Means may also be provided for controlling exit from a junction in accordance with the state of occupation of the succeeding track. Fig. 3 shows a pit shaft 30 to which full vehicles are dispatched via a right-hand track including vehicle counters 31, 32 and from which empty vehicles are dispatched via a left-hand track, and three junctions adjacent which, respectively, aerials J1, J2 and J3 are positioned. When a train has to enter junction J1 via the track associated with visual signal L1 and announcement aerial A1, it induces a signal in the aerial at a selected frequency dependent on the train type which operated a contact 1e (empty) or 1f (full), Fig. 4a. 'In the absence of a train on the junction or at the entry sections defined by announcement aerials A2-A8 (contacts RC2-RC8 made) relay R1 energizes whereby danger signal L1-G is shorted out proceed signal L1g is energized and a further contact opens to prevent subsequent energization of relays R2-R8. As the train passes the overlap between aerials A1 and L1 either contact JRC1e or JRC1f picks up and maintains relay 1 energized and either contact 1e or 1f releases to return signal L1 to danger. Relay R1 is maintained energized until the train leaves junction J1. Full trains routed to the pit shaft from junctions J2, J3 via the track sections associated with aerials A9 and A10 are controlled by visual signals L9 and L10 each of which includes in its control circuit a contact which is opened when counters 31 and 32 determine that the entry track to the shaft is full.

Title: Optical recording
IPC: G11B7/24085
Filed: 1974-06-28
Abstract: 1479294 Optical recording PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 28 June 1974 [2 July 1973] 28824/74 Heading G5R In an optical record and playback arrangement for disc records in which the track width is less than the diameter of the radiation playback spot and in which the average number of recorded areas g per unit length of track varies e.g. as in a video disc with a frame recorded in each turn of the track, the width of the recorded areas is increased in proportion to the increase in said average number. The arrangement is particularly described with reference to a reflecting optical record of the type having areas g which vary in length with the recorded information and which are depressed  wavelength of the playback radiation so that an antiphase radiation is produced in the playback detector as an area g is scanned in cancelling relationship to that reflected from the land 3 between tracks and the space t between recorded areas. As the length of the recorded areas decreases the average amplitude variation of the detected signal also varies so the width of the areas j is increased to compensate. In addition the non-linearity evidenced by the detector signal dropping to more than half the difference between maximum and minimum before the start of an area reaches the mid point of the playback spot, is compensated by shaping of the leading and trailing ends of the recorded areas. Figs. 9 and 10 (not shown). Recording apparatus for the disc for producing these changes in the shape of the recorded areas is described Fig. 11 (not shown).

Abstract: 261,772. Paisseau, J. Nov. 21, 1925, [Convention date]. Addition to 207,144, [Class 70, India-rubber &c.]. Extrusion presses; moulds; moulding artificial mother-of-pearl; pressing-plungers; pipes and tubes.-The process of the parent Specification wherein a mass containing brilliant particles is so formed as to draw the particles parallel to one another, is modified to ensure that all the particles are oriented into parallel planes, so that the sheets obtained are uniform in appearance over their whole surface. This may be done in an extrusion press, Fig 5, the necessary conditions being that the mass must be sufficiently plastic and the pressure applied regularly without shock, the nozzle 5 must be free from irregularities and shaped to prevent the formation of eddies, and the brilliant particles must be uniformly distributed throughout the mass. Another method of producing the same result is shown in Fig. 11, in which the mass is pressed between spring-held side plates 7 by a piston 10, 11, capable of expanding. 'Other methods described comprise extruding the mass through an annular die, the central member of which is held by studs shaped to prevent eddies, and cutting the tube longitudinally as it emerges, and moulding the mass in an annular press having extensible walls by applying radial pressure to the interior wall. When sheets are pressed into blocks, the sheets should be of such a size as to fill the mould without any space being left between the edges of the sheets and the sides of the mould.
