Title: Preliminary registering apparatus for photographic printing machines
IPC: G03B27/06
Filed: 1932-07-25
Abstract: 387,244. Photographic printing. machines. EUREKA PHOTO MECHANICAL EQUIPMENT, Inc., 33, West 60th Street, New York, U.S.A.-(Assignees of Mazzocco, D. V. ; 2103, Tomlinson Avenue, New York, U.S.A.) July 25, 1932, No. 20911. Convention date, Aug. 13, 1931. [Class 98 (ii).] In a preliminary registering-apparatus for photographic printing-machines of the kind comprising a registering frame and a negative frame having adjusting devices mounted thereon, the devices are adjusted by a displacement of the registering frame and are adapted to serve as supports for the negative frame when this is placed in the photo-composing machine. In the form shown, the negative frame C, Figs. 1 and 10, is provided at each corner with a diagonally extending flange 38 which abuts against upstanding posts 41, 42, carried by the supporting table A. The frame is clamped to the table by the posts 42 which, by means of a manually operable bolt 44, can be made to slide inwards upon a bracket 45 pivoted to the table. The registering frame B is supported at each corner upon studs 12 which are screw-threaded into the table A and which carry sprocket wheels 14. The studs are rotated in unison to raise or lower the frame B by a spring-controlled endless chain 15 passing around each sprocket. The frame B is formed with laterally extending lugs 26, Fig. 9, which are each slotted to receive a cam 28 formed on a shaft 29 which is journalled in a bearing on the table A. These bearings also form supports for adjusting bolts 33 which abut against vertical faces 34 on the frame B. By means of the cams 29 and bolts 33 the registering frame can be moved in any horizontal direction until the registering marks on a plate R carried thereby coincide with corresponding marks 31, 36 on the negative N. Each flange 38 of the frame C is formed with a slot 48 and a hole 47, which latter accommodates a tubular positioning sleeve 49. This sleeve is formed with a hemispherical end 50 which is adapted to seat within a member 51 secured to the frame B. A locking bolt 53, passing through each sleeve, engages with a nut 52 in the member 51 and, by engaging with the upper end of the sleeve, is adapted to lock it in any angular position it may assume. In operation, the negative frame is placed in position between the posts 41, 42 with the plates N, R lying face to face; the locking bolts 53 are then manipulated and the frame B lowered slightly by means of the chain 15. The registering marks on the plates N, R are then brought into coincidence by manipulating the cams 29 and bolts 33. The sleeves 49 are now in the correct angular positions which they are to occupy when placed in a photocomposing machine, such as that described in Specification 390,965. In this position, each sleeve is locked by a screw-threaded split sleeve 57 which is actuated by a nut 59 and which engages in a conical seating of a sleeve 58 secured to the frame C.

Title: Improved plasticising and fire-proofing compositions comprising halo-alkyl phosphoric acid esters
Inventor: SMITH GORDON ERNEST
IPC: C08K5/521
Filed: 1964-05-21
Abstract: Polymethyl methacrylate or cellulose acetate contains, as a plasticizing and fire-proofing composition, a composition comprising a preponderance, i.e. at least 70% by wt., of a mixture of a mono-(halogen-substituted alkyl) phosphoric acid and a di-(halogen-substituted alkyl) phosphoric acid prepared by heating POCl3 with a tri-(halogen-substituted alkyl) phosphoric acid ester to produce a reaction mixture, adding water to the reaction mixture in a substantially stoichiometric proportion and removing the HCl formed (see Division C2).  A specified composition contains the mono- and di-basic acids (ClC2H4O)2PO(OH) and ClC2H4OPO (OH)2.ALSO:A composition comprising a preponderance, i.e. at least 70% by weight, of a mixture of a mon-(halogen-substituted alkyl) phosphoric acid and a di-(halogen-substituted alkyl) phosphoric acid is obtained by heating phosphorus oxychloride with a tri-(halogen-substituted alkyl) phosphoric acid ester to produce a reaction mixture, adding water to the reaction mixture in a substatially stoichiometric proportion to hydrolyse acid chloride groups present and removing the HCl so formed.  The first stage of the reaction is generally effected at 90-100 DEG  C. and the reaction mixture at the end of the first stage contains at least 70% by weight of the mono- and di-acid chlorides. The hydrolysis is effected at a temperature not exceeding 70 DEG  C. and the hydrogen chloride is then suitably removed by blowing nitrogen through the mixture at 90-100 DEG  C.  The ratio of the mono- and di-acids in the final composition is suitably 2:1 to 1:2 by weight.  An example of the phosphate starting material is tri-(2-chloroethyl) phosphate.  The stoichiometric amount of water required is 3 mols. per mol. of POCl3 used and the product may be treated with H2O2 to lessen the discoloration.

Title: Improvements in and relating to the production of dyestuffs from benzanthrone
IPC: C09B3/22
Filed: 1926-08-26
Abstract: 281,016. British Alizarine Co., Ltd., Dawson, W. H., and Beghin, P. Aug. 26,1926. Violanthrone and isoviolanthrone. - The non- dyeing by-products obtained in the preparation of violanthrone and isoviolanthrone by alkaline condensation of benzanthrones or Bz1-halogenbenzanthrones are subjected to a further treatment with alkali at high temperature for the purpose of obtaining dyestuffs. Preferably the second alkali fusion is of a different nature from the first; thus if the original alkali fusion of a Bz1-halogenbenzanthrone is carried out with alcoholic potash the by-products react more readily with aniline and potash to give pure violanthrone, whereas if the original fusion is effected with aniline and potash (see Specification 275,283) the by-products readily yield isoviolanthrone on treatment with alcoholic potash. According to examples, (1) crude isoviolanthrone (obtained by an alcoholic potash fusion) is extracted with boiling aniline to dissolve impurities which, after removal of aniline are heated with caustic potash and aniline; the violanthrone obtained may be purified bv treatment with organic solvents such as aniline, nitrobenzene, or xylene; (2) the by-product obtained in the production of violanthrone, according to example 1 or 2 of Specification 275.283 is fused with alcoholic potash to give a dyestuff of the isoviolanthrone type which can be purified by extraction with aniline, xylene, nitrobenzene, or pyridine. Alkali metal alcoholates or anilides are also specified as alkaline condensing agents.

Title: Improvements in or relating to non-woven textile fabric and method of making the same
IPC: D04H1/52
Filed: 1965-05-19
Abstract: A non-woven fabric comprises a batt of substantially parallel fibres extending in the widthwise direction which is provided with elongate spaced apart rows of stitches extending in a direction perpendicular to the fibres and passing from one face of the batt to the other, the rows of stitches being formed of two elongate yarns having one stitch component in the row of stitches and another component between the rows of stitches to form interconnecting threads therebetween to give greater stability to the fabric.  The fibres preferably pass from an opening machine i.e. a carding machine, to a cross-lapping device, disposed above a conveyor, in the form of a batt with lengthwise extending fibres.  The fibres are then deposited on the conveyor in the form of a batt with widthwise extending fibres and are conveyed to a stitching apparatus having a plurality of needles, the resultant batt is then passed through a napping apparatus where the batt is napped to a sufficient depth to cover the stitches.  The yarn used for stitching is preferably spun staple yarns to prevent breaking of the yarns during napping.  Examples of suitable fibres are cotton, wool, nylon, polypropylene, or viscose or acrylic fibres.

Abstract: 1, 035, 671. Combing-machines. JAMES HILL & SONS Ltd. March 13, 1964 [May 28, 1963], No. 21317/63. Heading D1N. A combing machine having two sets of pins, e.g. on comb circles, has a portion of each set adjacent and approximately perpendicular to the other portion. The sets of pins are arranged to move so that pins of each set move downwardly relative to each other. Fibres in sliver form are presented to the pins 2 of a large circle 1 and dabbed lightly into them by a brush 5. As alternatives to the brush 5 press knives or other devices may be used. During rotation of the circle 1 the protruding fringe of fibres is moved into the pins of the circle 3, which circle moves in a direction having a downward component relative to the other set of pins, thereby completing the dabbing operation. Some fibres of the fringe are carried away by the circle 3 and remaining long fibres are drawn off by detaching rollers 6. Other detaching rollers 6 draw off fibres from the circle 3, and combine the two bands of drawn off fibres. Knives 8 remove noil. A large number of circles 3 may be used in association with a large circle. The small circles 3 may be mounted to rotate with their ancilliary equipment within a stationary large circle. Many combing machines as described may be arranged alongside one another to form a single compound machine.

Abstract: 359,451. Master control of several D.C. motors. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. July 15, 1930, No. 21384. Convention date, July 22, 1929. [Class 38 (iii).] Varying electromotive force; field control; reversing.-A group of motors fed from a common generator on the Ward-Leonard principle, are controlled from one or more operating points at each of which are four controlling switches, a separate switch being used for effecting normal operation, for stopping all the motors, for running a single motor forward, and for running a single motor in a reverse direction. For normal operation a button r is pressed to energize a relay f of a motor I which in closing completes the circuit of a relay f of a motor II. The armature circuits of the motors are thus completed in turn. When the relay f of the last motor III is closed its auxiliary contacts energize a relay n which closes and maintains the currents of the relays f independently of the button r at the same time a relay h is closed to energize the fields of all the motors through regulators i. The relay h also completes through a switch 27 on the main generator switch b the circuits of one of the sets of contactors k which close the circuit of the field of the generator a, which also has a damping winding d. Thus all the motors start simultaneously in a forward direction. The field regulators i are short circuited by relays g while the button r is depressed. If a button s is depressed the associated motor and all those above it start in a similar manner, the motors below it remaining at rest. If a switch q is moved from the position shown to its other position and the corresponding button s is pressed that motor alone will start. To stop any or all of the motors a button t is pressed. Thermal releases o act in a similar manner upon excess current passing in any motor. If a button u be pressed all the motor circuits are broken but the motor corresponding to the particular button pressed is caused to run in a reverse direction by means of a relay p. In place of hand-operated switches q switches which are moved automatically by the depression of the buttons s may be used so that it is necessary to actuate an additional switch in order to obtain a partial operation of the motors.

Abstract: 412,431. Valve-gear for percussive tools. HARDYPICK, Ltd., and RAYNER, P. T., Mining Engineering Works, Heeley, Sheffield. July 29, 1933, No. 21396. [Class 122 (ii).] A percussive tool is provided with a differential sleeve valve e which is moved in one direction by compression and in part in the other direction by main pressure fluid acting constantly upon a valve area, and in part by reduced pressure fluid acting upon an area which is periodically put to exhaust by a piston controlled passage. The head f of the tool accommodates a trigger g for actuating a supply valve h. The fluid passes to the cylinder through a duct k and radial ports m. Fluid pressure passes to the rear of the cylinder across the end of the valve, and to the forward end of the cylinder across the outside of the valve and by passage n. The exhaust passes through central parts x. A forward auxiliary exhaust passes along passage n around the valve, and through passages z, z. The valve box is stepped at r so that the periphery of the collar of flange q of the valve is clear of the wall when the valve is forward. Clearance is also provided around collar p<1>. The supply to either cylinder end is independent of valve wear. The annular recess t is supplied with leakage pressure fluid along the valve and is periodically put to exhaust by passage v, ports w, grooves in the piston y and ports x. During the forward piston motion, the grooves y delay the closure of ports w. The movement of the valve to the left is effected by the constant pressure on flange q and the pressure on shoulder s.

Abstract: <PICT:0833290/III/1> In the deposition of silicon from a silicon compound, e.g. silicon tetrachloride or trichlorosilane, on to an electrically-heated wire 4 of silicon, the wire 4 is heated by an electric current flowing substantially parallel to the longitudinal axis of the wire and the effect of gravity on the wire is at least partially counter-acted by interaction of the electric current and a magnetic field 5.  The electric current and the magnetic field may be adjusted during the process to maintain to a desired extent the supporting force for the wire.  Preferably the strength of the magnetic field is increased downwardly by using magnets, the pole faces of which are so shaped that the gap between them decreases in a downward direction (Fig. 2, not shown).  The current through the wire may have direct and alternating components, the direct current being used for support of the wire and the alternating current for control of the heating.  Alternatively two alternating currents of different frequency may be used with an alternating magnetic field of frequency corresponding to that of one of the currents.  The production of single crystals may be facilitated by use of a current of frequency in the range 10-100 cycles/second to give a hammering effect on the wire.  The ends of the wire and any mechanical supports therefor may be cooled.ALSO:In a modification of the process of the parent Specification, for producing pure semi-conductor material, the carrier body is heated by an electric current flowing substantially parallel to the longitudinal axis of the carrier body and the effect of gravity on the carrier body is at least partially cancelled by interaction of the electric current and the magnetic field.
