Title: Improvements relating to magnetic core memory matrices
Inventor: LOUGHHEAD WILLIAM ALBERT EDWAR
IPC: H04Q11/04
Filed: 1961-11-06
Abstract: 960,655. Magnetic core matrix stores; counters. ERICSSON TELEPHONES Ltd. Oct. 23, 1962 [Nov. 6, 1961], No. 39713/61. Headings G4A and G4C. Data characters are read out from a column of a magnetic core matrix to a magnetic core register, from which they may be re-entered unchanged or in modified form by selecting one of two read-back circuits. As shown each column of cores 12 stores one of the digits 1-6 in a two-out-of-four code and is read out by a pulse from 14, the pulses on two of the lines a o -d o  inhibiting the setting of all but one of cores 16 by a pulse at P3 which also sets core REP. Each core 16 has four output windings linked with it, two associated with gates H and two with gates J for unmodified and modified re-entry respectively. A pulse at P5 resets the selected core 16 and core REP to open gates H for unmodified re-entry in the matrix; if modified entry (in this case increasing the count by one in the code specified) is required a pulse at α before the P5 pulse resets REP and sets ADV so that gates J are opened at P5 time. A pulse at # is used when the possibility of modification of a particular number stored is required. Clearing of a column is effected by omitting pulse P3 in the sequence described above. Fig. 4 (not shown) illustrates a similar arrangement in which the data stored in a column can be modified in other ways (not having arithmetic significance) by one or more of a number of control pulses on different circuits linking various cores. Specifications 875,875 and 900,033 are referred to.

Abstract: 366,671. Dashpots. GLOVER, F., 10, Labassa Grove, Caulfield, Victoria, Australia. Dec. 29, 1930, No. 39057. Convention date, Jan. 31. [Class 108 (iii).] The piston 20 is moved along its cylinder by cam mechanism operated by rotation of the shaft 6 arranged coaxially with the cylinder. The shaft is rotated by the arm 7 and carries a member 11 having an annular cam 13 which engages a conical roller 23 on the piston. Rotation of the piston is prevented by the head of the pin 22 which rides in a slot 25 in the cylinder wall. The piston is held up to the cam by a spring 24 and during upward movement oil passes freely through a valve 26. On downward movement, the oil flows through a slot 35 in a stationary central tube 29 which can -be adjusted axially by turning a screwed rod 30. The rod is rendered oiltight by a valve seating 37a and a gland 43. A port 16a connects the spring chamber and the oil cylinder when the piston is raised.

The cylindrical wall of the screw press is formed of parallel bars between which liquid is expelled in section 16 and vapour is vented in section 15. The polymer is next mechanically worked in section 17 and then passes through the annular orifice between adjustable ring 95 and collar 96 into chamber 112 where further vaporization and venting of volatile liquid takes place. The devolatilized polymer is conveyed to die plate 130 where is is forced through an annular array of nozzle-orifices to a rotary cutter. Plate 130 is heated by passing steam through an enclosed chamber therein. The nozzle-orifices may be exchanged with others of different size. The annular orifice between ring 95 and collar 96 is adjusted by moving the ring toward or away from the collar by pinion 103.

Title: Improvements in or relating to pressure rollers
Inventor: VARGA JOHN MAXIMILIAN JULES
IPC: D01G15/96
Filed: 1962-10-26
Abstract: A pair of rollers mounted for movement towards and away from each other and for angular off-setting adjustment are provided with means whereby angular adjustment results in a corresponding adjustment of pressure between the rollers.  In one form, Fig. 6 (not shown), swivel bearings for upper and lower rollers are carried in a frame 5 pivotable about the end 6 of the upper roller for angular adjustment of the lower roller relative to the upper.  This adjustment is effected by manual movement of a cam 24 with which is associated another cam that alters the pressure between the rollers by influencing a coil spring 17.  Adjustment of a screw 27 alters the spacing of the rollers.  Another form of the apparatus, (Fig. 9 not shown), has the lower roller carried on arms that are laterally adjustable with simultaneous adjustment of the pressure of a spring acting against the arm.  Yet another form, (Fig. 10 not shown), has the upper roller mounted in laterally slidable bearings with straight cam surfaces alongside against which roller-weighting plungers slide.

Abstract: 1,019,737. Splitting rocks. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Oct. 26, 1962 [Oct. 30, 1961], No. 40592/62. Heading B3E. [Also in Divisions H1 and H4] An apparatus for splitting non-metallic brittle material, such as rocks, comprises a transmission line 11 and a radiator 12, theradiator and line being capable of insertion into a hole 2 formed in the material, a pair of electromagnetic energy generators 7, 8 for applying a source of ultra-high frequency energy whereby the energy from the source can be fed along the line and radiated into the block by the radiator. The generators are formed by two magnetrons 7, 8 having conductors 13, 14 entering into a waveguide constituting the transmission line. The waveguide, which is of reduced diameter at its forward end for insertion into a hole 2 in the rock, has two pairs of guide strips 15, 16 provided in its inner wall, the ends of the strips extending beyond the waveguide to thereby form the radiator. In operation, when the magnetrons are energized, the electromagnetic field produced by the conductors 13, 14 propogate in the gap between the strips 15, 15 and 16, 16, respectively, to thereby produce local dielectric heating in the rock thus causing it to split. The radiator may be protected by a cap of polytetrafluorethylene.

IPC: G03C7/14
Abstract: 406,377. Colour photography. MURRAY, H. D., and SPENCER, D. A., 118, Fulham Road, South Kensington, London, and THORNTON, J. E., 8, Hill Street, Jersey, Channel Islands. June 24, 1933, No. 23131. [Class 98 (ii).] In producing lenticular positive images representing two or more colours by successive projection printings from component continuous - tone colour - record negatives, a lenticular positive bearing component images coloured in themselves is obtained by developing, and toning without fixing, each component record after it has been printed and before printing the next component. Such a film requires no colour filter for its subsequent projection. The lenticular film may bear an ordinary non-panchromatic sensitive layer, and the several records may be printed on the lenticular film rapidly one after another by printing machines in tandem. The printing of a two-colour positive from orange and green component negatives, and of a three-colour positive from blue, green, and red component negatives are instanced. Alternatively, component continuous-tone positives may be used, the resulting lenticular negative being reversed to a positive after development. A modification is described in which the component images are printed on a plain sensitive film against the illuminated side of which a plain transparent lenticular film is pressed during printing, the successive images being coloured seriatim as before. The resulting positive requires no lenticular screen or colour filter for subsequent projection, and the lenticular film may be differently inclined to the sensitive film for each printing so that the colour records are printed at an angle to one another, the blue elements for example running longitudinally the green diagonally, and the red transversely.
