Title: Process for cleaning printing plates
IPC: B41N3/08
Filed: 1964-10-02
Abstract: 1,074,289. Cleaning printing plates. KALLE A.G. Oct. 2, 1964 [Oct. 4, 1963], No. 40257/64. Heading B6C. [Also in Division G2] Tone is removed from the non-image areas of an exposed negative working light-sensitive material during or after preparation therefrom of a planographic or offset printing plate by treating the material or plate with cleaning solution comprising a lacquer- and greasedissolving organic solvent and a small amount (at least 0.01 equivalents/litre) of HC1, HBr or a salt of either of them with an organic amine or amide having a dissociation constant below 10-<SP>3</SP> at 25 C. The treatment may be carried out after inking up or lacquering the plate, or after development but prior to inking up or lacquering, or even immediately after exposure. In the latter case the cleaning solution may in certain cases also be used as the developing solution. The treatment may be repeated one or more times, the plate being cleaned with water after each treatment. A wide variety of solvents is specified, and the solutions may also contain water, an alcohol, a hydrocarbon, a dye, and/or a cellulose ether, suitable examples being given.

Abstract: 1502901 Lapping arm apparatus ALLIS-CHALMERS CORP 2 Oct 1975 [7 Oct 1974] 40324/75 Heading B8H A load carrying mechanism 12 supported on a material handling vehicle 1 and adapted to be interchangeably connected to different load carrying attachments 2, comprises at each side of an upright support 13 on the vehicle, an attachment supporting pivoted elevatable boom 15 and an attachment levelling arrangement including pivotally interconnected levelling link 35, cross arm 28 and levelling cylinder 30, the pivotal connection on the cross arm being variable depending on the load carrying attachment being used. The boom 15 is pivoted about its connection 16 with the support 13 by an hydraulic arm 19 and its other end 22 supports the base of a fork lift mast 2 which at a higher level is pivotally connected to the levelling link 35. The levelling cylinder 30 is operated from an operator position 5 on the vehicle to maintain the mast 2 vertical during raising of the beam 15. The quadrilateral linkages 70, 74, are arranged to diverge and converge such that the mast is tilted rearwardly during raising of the boom 15 when the levelling cylinder 30 is not operated. In the embodiment of Fig. 2 (not shown) the mast is replaced by a bucket and the connections between the cross arm and levelling link and cylinder are altered to provide for a greater range of movement of the bucket than the mast. The levelling cylinder may also be charged to give a greater stroke of reduced power.

Abstract: 1522143 Twisting slivers to form roving: sliver creel: winding roving PLATT SACO LOWELL Ltd 19 Sept 1975 [20 Sept 1974 (2)] 41090/74 and 41091/74 Headings D1F and D1J Winding apparatus comprises means for supporting first and second package tubes in parallel, a material delivery arm arranged to deliver material for winding first to one then to the other of the packages, the arm being arranged to contact each, package at a winding-on point and to deliver material at the point direct to the package under a winding tension localised by the arm in the region of the point, and traversing means for traversing the arm to form parallel-build packages on the tubes. The machine described, Fig. 1, comprises sliver creel 11, sliver drafting and twisting section 12 and roving winding section 13.  Creel. Platform 14, Fig. 4, on legs 15 supports rails 17 over cams 18 from which slivers 5 are drawn to pass over rails 17, through guide 19, over drive rollers 20, around guide pins 21 and through forwarding rollers 22. End break detectors are located on either side of rollers 20 to stop the machine. Drawing and twisting. Slivers 5, Fig. 5, delivered by chute 23 are drafted at 24 and are given alternating twist by driven rollers 29 which are axially reciprocated outof-phase. The twisted slivers twist around one another in pairs to form three twofold rovings R. Winding. Two-fold rovings R, Fig. 5, are each wound at a station supporting oppositely driven package tubes 42, 43 mounted on driven stub shafts on members 38, 41, Fig. 7. The shafts are axially movable to release the tubes. Each roving is traversed by a reciprocated bar 46 and depending arm 45 to wind package 48. The arm, having an end shaped shown in Figs. 8 to 10, tensions the roving without allowing the tensioned roving to remain unsupported over a distance longer than the mean fibre length. The arm has blade 55 lying tangential to the package and pressing on the package. When package 48 is wound, bar 46 is moved to the right of tube 43, Fig. 7, so that arm blade 55 bears against the left hand side of tube 42. The running roving is snagged on teeth, directed inwardly and in one direction around the tube circumference, in tube groove 58, and the oppositely rotated tubes 42, 43 break the roving. Further traverse causes the roving to move from one side to the other of arm blade 55, Figs. 8 and 10. The package tubes are driven to ensure that the roving runs at constant speed, the traverse of bars 46 is controlled to build double taper packages and the traverse rate is decreased with package diameter, and the package diameter is monitored to move bars 46 so that blades 55 lie on the package circumferences. The tube driving and traversing are effected by undisclosed means.

A punched or magnetic tape 2 carries information for controlling an electric typewriter, each line of characters has a corresponding line number on the tape, this number being accompanied by a carriage return character and followed by the characters for that line. Another tape 4 carries amendments to be made to the information on the tape 2, each set of amended characters being preceded by the appropriate line number and the carriage return character. On depressing start keys 15 and 17, tapes 2 and .4 are advanced until the respective first line numbers are under readers 1, 3. Assuming the line number on tape 2 to be less than that on tape 4, tape 2 is advanced by a signal from terminal 27 of comparator 22 and gates 36 are opened to enter the information read from tape 2 into a store, typewriter or punch 39. Each carriage return character is detected at 53 and steps generator 55 to produce successive line numbers as each line of characters is entered into 39. When the line numbers on tapes 2 and 4 are the same, comparator 22 produces an output at terminal 28 to advance tapes 2 and 4 simultaneously, only the information from tape 4 being entered into 39 via gates 48.

Title: Improvements in and relating to methods of producing boron phosphide
IPC: C01B25/06
Filed: 1964-10-23
Abstract: Boron phosphide is produced by reacting vapour state boron sulphide with vapour state elementary phosphorus or vapour state phosphorus sulphide.  The boron sulphide may be B2S3, B2S5 or mixtures of boron-sulphur compounds of different compositions.  The reaction may be at 400 DEG -1100 DEG  C. for 12 hours and may be utilized for the recrystallization of boron phosphide.  For recrystallization boron phosphide (BP) is heated in a closed quartz tube with sulphur at a first position e.g. at above 1100 DEG  C. forming boron sulphide and phosphorus and/or phosphorus sulphide.  At a second position and at a lower temperature, e.g. 600 DEG  C., boron phosphide is re-formed by the reverse reaction.  The closed tube may contain a rare gas atmosphere or may be exhausted. The quantity of sulphur at the first position may be smaller than the stoichiometric quantity. The boron phosphide may be washed with dilute nitric acid and hot de-ionized water.
