Abstract: Ethylene is polymerized in the presence of a catalyst formed by contacting a solid halide of a metal of Group IVa, Va, or VIa of the Periodic Table, the metal having in the halide a valency which is lower than its maximum valency, with an aluminium alkyl compound and in the presence of a solvent for the ethylene in which the halide is insoluble.  Specified halides are the trichlorides of vanadium, zirconium and titanium and titaniumdichloride.  Specified aluminium compounds are triethyl aluminium and diethyl aluminium monochloride. The molar ratio of the alkyl compound to the halide is preferably from 0,5:1 to 10:1.  The specified solvent is n-heptane.  The polymerization may be effected at below 120 DEG C. at from 0,5 to 50 atmospheres.  The product is an exclusively linear polyethylene having a specific gravity of 0,95 to 0,98 and a Vicat softening temperature under a load of 1Kg. of at least 128 DEG C.

Abstract: 1,205,422. Lithographic plates. FUJI SHASHIN FILM K. K. Aug. 11, 1967 [Aug.12, 1966], No. 37117/67. Headings G2C and G2M. Lithographic printing plates are prepared by developing an imagewise exposed element containing at least one hydrophilic silver halide emulsion layer with an aqueous alkaline solution in the presence of a developing agent which is converted into an oleophilic dimer when oxidized, so that an olephilic image of the dimer is formed. Specified developing agents are thio-indoxyl and its 6-methyoxy and 6-ethoxy derivatives, indoxyl, 4-hydroxyiso-carbostyril, 4-methoxy and 4-ethoxy 1-naphthols, pyrogallol 1, 3-dimethyl ether, 0-aminophenyl, 2-amino-3, 5-dimethyl phenol, 1 -phenyl-3-methyl-4-amino-5-pyrazole, 1, 5- dihydroxy naphthalene, hydroquinone, and N- ethylphenylenediamine and various N-and/or 3- substituted derivatives thereof. The developing agent may be in the alkaline soln, the emulsion or a layer between the emulsion and the support. The oleophilic image may be formed in the emulsion layer or, if a positive image is required, in a fogged silver halide emulsion layer overlying the photo-sensitive emulsion layer. Positive images may also be formed by using a direct positive emulsion, or by carrying out a first development with a non-tanning developing agent which does not form an oleophilic dimer and then a second development with a solution containing a fogging agent and the dimerizable developing agent. After development the elements are preferably processed in a stop-bath.

Title: A control system for a feed cylinder for a rock drill
IPC: E21B19/087
Filed: 1961-10-17
Abstract: 998,463. Rock drills. INGERSOLL-RAND CO. Oct. 17, 1961 [Oct. 27, 1960], No. 37216/61. Heading B4C. A control system for a double-acting feed cylinder 14 of a rock drill 10 includes a housing 20 having a fluid supply passage 52, a passage 48 to the chamber 14A of the cylinder and a passage 50 to the chamber 14B of the cylinder. The housing is the handle of the drill which has internal passages connecting the passage 52 with the air supply hose 18, and the passages 48, 50 with the chambers. A valve 90 is slidable to supply and exhaust the chambers, and a valve 74 is rotated to control the pressure of the supply to the chamber 14A. With the valve 90 set, as shown in Fig. 3, and the valve 74 set as shown in Figs. 6 and 7, air is supplied to the chamber 14A, to extend the cylinder, by passages 52, 58, groove 106, passage 60, port 80, chamber 76 of the valve 74 and passage 48, whilst fluid is exhausted from the chamber 14B by passages 50, 54 and outlet 114. Anti-clockwise rotation of the valve 74 (as viewed in Figs. 6, 7) progressively prevents fluid flowing into the chamber 76 and thence to the chamber 14A and progressively opens a port 64 to vent the chamber 14A. Movement of the valve 90 until the groove 106 is directly opposite the passage 58 stops fluid supply to the cylinder. Further movement of the valve 90 to its extreme right-hand position directs pressure fluid from the passages 52, 58 through the groove 106 and passages 54, 50 to the chamber 14B to retract the cylinder, fluid from the chamber 14A being exhausted through the passages 48, 62, the groove 102 and port 43.

Title: Improvements in and relating to apparatus for conversion of electric currents
Filed: 1956-12-08
Abstract: 875,638. Converting. LEWIS, T. X. Nov. 7, 1957 [Dec. 8, 1956], No. 37574/56. Class 38 (2). A rectifying arrangement supplying a load with D.C. from transformer 7 comprises two pairs of saturable chokes 1c, 2c; 3c, 4c each having in series an isolating switch 1, 2, 3, 4 driven by synchronous motor 5. The switches of a pair close for alternate whole cycles and a small overlap, corresponding switches of different pairs operating 180 degrees displaced. Load current passes through the saturated choke 1c for one half of the cycle when switch 1 is closed, and is blocked by the reversing magnetization of the choke during the other half. During the next cycle, choke 2c first conducts and then blocks load current. Chokes 3c, 4c and switches 3, 4 operate similarly to pass current during the non-conducting half cycles of the first pair, so that the circuit operates as a bi-phase fullwave rectifier. During the cycles when their associated switches are open, the magnetization of the chokes may be reset by current through windings 1e, 2e, 3e, 4e controlled by valves 1#, 2f, 3f, 4f, D.C. premagnetization is provided by windings 1d, 2d, 3d, 4d. In a modification, the magnetization of each choke is reversed by passing the load current carried by the other choke of the pair through a winding on the first choke. The small current passing through each blocking choke is allowed to fall to zero by retarding the opening of its associated switch (thereby giving the overlap) or through a bypass valve la, 2a, 3a, 4a controlled by a series switch 1h, 3h, or a grid 2h, 4h.
