Abstract: 417,206. Removing bearings &c. from shafts. HICKLEY, H. N., Rowford House, Taunton, Somerset. April 24, 1933, No. 11936. [Class 61 (iii).] A ball bearing, hub &c. extractor comprises a ring d with a conical bore and an inner ring formed of two or more segments e, f with conical outer surfaces to engage the ring d and cylindrical inner surfaces lipped at h to engage the rim of the bearing a, which is pulled off its shaft by means of an extractor device with arms engaging behind the ring d.

Title: Improvements in or relating to apparatus for measuring brinell impressions
IPC: G01N3/42
Filed: 1935-04-18
Abstract: 445,983. Linear - dimension gauges. KENT, Ltd., G., 199, High Holborn, London, and BROOMHEAD, R., 343, Dunstable Road, Luton, Bedfordshire. April 18, 1935, No. 12077. [Class 106 (ii)] A device for measuring Brinell impressions comprises a plunger rounded at the end to standard size which slides in a tubular body against the influence of a spring and which when placed in the impression and forced against the spring until the end of the tubular body engages the work causes the hardness to be indicated on a dial gauge carried by the body. The body portion is made in two parts 10a, 10b which screw together. The part 10b which is bored to receive a plunger 14, and the latter are hardened and ground. The upper portion of the bore is widened to receive a spring 20 which sur rounds the plunger bearing against a collar 22 on the plunge] and against a hardened and ground bush 24. The projecting end 14a of the plunger is detachable being screwed into the plunger and is made of cast steel ground and polished to the correct radius, e.g. 5 m.m. where a 10 m.m. ball is used. This ball end 14a is flattened off at the extreme tip to prevent " bottoming " in the impression. A dial indicator 28 is clamped in the bore of the part 10a by a screw 34, the plunger 30 being adapted to be engaged by the plunger 14. A set screw 36 serves to clamp the latter while securing and changing the end 14a.. A check gauge Fig. 3 serves to set the device which is placed on the block 40 of standard hardness which should be indicated by the gauge 28 when the ground surface 16 engages the block 40.

Title: Lithographic printing machine
IPC: B41F7/24
Filed: 1950-05-15
Abstract: 685,938. Printing machines. MULLEN, W. G. May 15, 1950, No. 12078/50. Class 100 (ii). Damping - apparatus for lithographic machines.-A continuous film of aqueous liquid or solution in excess of that required for moistening the non-printing areas is applied to a printing plate, against which a continuous jet of air is then directed to remove substantially all the liquid from the printing areas and to reduce the thickness of the film on the non-printing areas to that required for repelling ink therefrom. In a sheet offset press, Fig: 1, an independently driven damping roller 11 is held just out of contact with the printing plate 4, being mounted on a bell-crank 12 pivoted to the plate cylinder at 14, and urged towards the plate by a spring 16, an adjustable screw 18 determining the size of the gap. Liquid is applied to the plate and surplus removed by a jet from an elongated air nozzle 25, the air line 30 having a control valve 31 and pressure-regulating valve 32. A depression in the cylinder between the ends of the plate provides a scoop 8. When the scoop reaches the roller 11, the latter is swung out of operative position by a cam 20. As the scoop approaches the nozzle 25, the excess liquid runs into it and is blown out by the jet, being conducted by baffles 34 back to a trough 15 in which the roller 11 rotates. With a nozzle delivery slot 0.01 inch wide and 0.012-0.015 inch from the plate, an air pressure of 1¢-5 lbs. gauge is satisfactory at a plate speed of 100-250 ft. per minute. In another form, for attachment to a web offset press wherein the plate is wrapped almost completely round the cylinder, no scoop is provided, only one baffle plate is used, and the damping roller is mounted on an adjustable plate on the trough and driven by a back-gear motor. As applied to a conventional sheet press, Fig. 3, the apparatus comprises a nozzle with a pair of adjustably spaced lips 130, 131, carried on arms 122 adjustable on a fixed shaft 120. The nozzle is connected by a flexible tube 135 to a supply line 136 leading to a compressor 138 operated by a motor 116. The trough 76 is divided into two sections by a partition 103. The excess liquid is returned by the baffle plates to the rear section and thence to a drain or to a return pipe 111 for re-use. An overflow pipe 110 from the front section also leads to the pipe 111. The pipe 111 leads to a reservoir 112, connected through a cartridge filter 114 to a centrifugal pump 115 and thence by a supply pipe 108 to the trough.

Abstract: 1302130 Television MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 13 March 1970 [14 March 1969(3)] 12208/70 Heading H4F A television-type cross-grid electroluminescent display panel comprising horizontal electrodes Y 1 -Y n  and vertical electrodes X 1 -X m  is scanned by applying sequentially to each of the horizontal electrodes a selection pulse (blanking pulses being applied to all the other horizontal electrodes except the selected one) and by applying simultaneously (by means of tapped delay line 21) a complete horizontal scanning line of video information to the vertical electrodes via brightness controls B 1 -B m . The blanking pulses reduce or eliminate cross-talk and are in phase with and have an amplitude of about one-third that of the selecting pulse. Counter 11 and pulse distributor 12 select the horizontal electrode to be scanned, on each received horizontal sync. pulse a successive pulse generator PG being activated. At the same time the second trigger pulse generator 13 delivers a second trigger pulse to all the pulse generators PG upon each occurrence of an horizontal sync. signal. The selected pulse generator which receives both pulses supplies a selecting pulse to the horizontal electrode whereas the other pulse generator which only receives the second pulse supplies the blanking pulses. Brightness control circuits B; sample the signal voltages simultaneously from the taps of the delay line (the horizontal line period-LC or acoustic delay line) under control of a sample signal from generator 32, and maintain them until a reset signal is applied about 40 microseconds after the sample signal. The brightness control circuits each preferably include a transistor whose resistance is varied in response to the video signal sample applied thereto (Fig. 4 and 6, not shown). In order that only a small output from the pulse generators PG is required to select a horizontal electrode an inductor is connected in series and a capacitor in parallel with each pulse generator (Fig. 2, not shown) a resonance effect being produced.

Title: Improvements in or relating to halogenation of aromatic hydrocarbons
IPC: C07C17/12
Filed: 1943-08-03
Abstract: Aromatic hydrocarbons (e.g. benzene) are halogenated (e.g chlorinated) by the introduction of the hydrocarbon, in liquid phase, and the halogen into the lower ends of each of a plurality of tube-like confined reaction zones arranged side by side and of substantial length with respect to their individual diameters, and separating the liquid from the gases discharging from the reaction zones, said reaction zones being severally encompassed along their lengths by a plurality of successive independent compartments adapted for contaihing heat-exchange media, whereby said reaction zones are subdivided along their lengths into a plurality of successive sub-zones which may be subjected to different conditions of heat exchange, the predetermined temperature conditions for optimum yields of halogenated compound being maintained in each of the said sub-zones.  Further halogen or hydrocarbon or both may be introduced to the partially halogenated hydrocarbon at the entrance to one or more of the said sub-zones of each reaction zone.  For a maximum yield of a monochloro product, the hydrocarbon is introduced at about 40-45 DEG  C.  When a polychloro compound is desired, part or all of the hydrocarbon injected into the reaction zone may be already partially chlorinated.  The process may be carried out in the apparatus of Specification 632,213, in which the reaction zones may be filled with packing material which may be impregnated with ferric chloride.  The Specification as open to inspection under Sect. 91 comprises also a process of counter-flow chlorination by introducing benzene at the top and chlorine at the bottom of the apparatus.  This subject-matter does not appear in the Specification as accepted.
