Patent GB-950595-A (GB)
Title: Synthetic paper-making fiber and manufacture of paper therefrom
IPC: D01D5/42
Filed: 1960-03-03
Abstract: A highly fibrillated wet-spun fibre of paper-making length made from an acrylo-nitrile polymer containing at least 80% by weight of acrylonitrile and up to 20% of a mono-olefinic monomer is made by fibrillating the fibres when they have a gel and uncollapsed structure.  Strong coherent paper products may be made from these fibres by interlocking of their fibrils.  The polymer may be a binary or ternary copolymer or mixture of copolymers, as long as the overall content of acrylonitrile units is at least 80%.  The Specification includes a list of olefinic monomers and examples of copolymers and blends.  The paper may be made by spinning a water-coagulable solution of the acrylonitrile polymer into a precipitating bath under conditions such that the solvent and bath liquid interchange to produce filaments having an uncollapsed structure, purifying the filaments, partially (but not completely) drying them, cutting them to fibres of staple length, fibrillating the fibres by beating them in an aqueous slurry, sheeting them out into a paper product, and drying this product.  The filaments may be stretched, washed, crimped or cut before fibrillation.  Octyl alcohol may be added as an anti-foaming agent during the beating, and deacetylated gum Karaya may be used as a suspending agent. Physical properties of the product such as tensile, tear and bursting strengths are improved by drying at high temperatures. Resins or potentially resinous materials may be used as binders. The fibres may be blended with other, e.g. cellulosic, fibres. The products may be sheets, boards, filter paper, moulded paper articles, currency paper, condenser tissue, electrical insulating paper and board, &c., and are resistant to chemicals.

Title: Improvements in or relating to indicating apparatus
Inventor: WELLS JAMES ALFRED
IPC: G01C19/34
Filed: 1948-04-13
Abstract: 652,051. Indicating-apparatus. MINISTER OF SUPPLY. March 13, 1948, No. 7699. [Class 106 (iv)] [Also in Group XX] Indicating apparatus comprises three members mounted side by side for an. gular movement about a common axis with the intermediate member serving as a carrier for balls, rollers or wheels through which angular movement relative to the carrier can be transmitted to the one outer member from the other and the one outer member is normally clutched to the intermediate member for angular movement as one therewith, and the other outer member is movable (a) axially toward the intermediate member to cause the balls, rollers or wheels to bear on the first outer member and declutch it from the intermediate member, and (b) angularly to adjust the angular position of the first outer member relative to the intermediate member. An aircraft instrument comprises an annular dial 1, for indicating direction against a mark 2, secured to the rim of an intermediate member 4 which is dished to accommodate an outer member 5 bearing a course-setting disc 6 flush with the dial 1. A stud 7 extends axially from the member 4 to support the member 5 which is pressed by a spring 8 into frictional contact with surfaces 11  of the member 4 so as to be driven angularly therewith by gyroscopic means coupled to a shaft 12. Balls 17, 18 are carried in holes in the member 4 and are disposed between the member 5 and a second outer member 14 with a toothed periphery, mounted loosely on the shaft 12. To declutch the member 5 from the member 4 and reset it relative thereto, a knob 25 is pressed against a spring 26 axially parallel to the shaft 12 so that its end rocks a lever 21 against a spring 23 and presses the member 14 and balls 17, 18 toward the member 5 to break the frictional contact between the members 4 and 5 and the knob 25 is turned so that a pinion 27 now in mesh with the member 14 drives the member 14 and through the balls 17, 18 also the member 5. In a modification, not shown, the resetting shaft may be at an angle to the shaft 12 and if at right angles it may co-operate directly or indirectly cam-fashioned with the member 4 to disengage the member 5 therefrom, thus obviating the lever 21. The balls 17, 18 may co-operate with V-shaped or bevelled tracks in the outer members 5, 14. Other forms of clutch may be used.

Title: Improvements in automatic stopping devices for electric lifts
IPC: B66B1/50
Filed: 1928-03-13
Abstract: 307,217. Smith, Major, & Stevens, Ltd., and Stevens, P. H. March 13, 1928, Cage lifts. - Electric lifts which are stopped at any floor by the attendant by the projection of a solenoidactuated roller mounted on the cage into position for engagement by a ramp in the well, are provided with a cam plate which projects the roller to the required position. A solenoid A mounted on the cage is connected to one end of a pivoted arm B, the other end of which carries a cam plate C which is interposed between a roller E on a pivoted arm F carrying one member of a normally closed circuit control switch G and a second roller J<2> on a pivoted lever J which carries a roller K engageable with a ramp L in the well. To stop the cage at a floor, the attendant operates a switch to energize the solenoid and thus raises the cam plate C so that the cam D strikes the roller J<2> and projects the lever J, the flat dwell D<2> of the cam maintaining the lever in the required position independently of variation of movement of the solenoid core. On approaching the floor the ramp L pushes the lever J inwards and through the cam plate and arm F opens the switch G and thus breaks the power - circuit. Similar mechanism is provided for stopping the cage when moving upwards. To automatically stop the cage at a terminal floor, the cam plate C, Fig. 4, carries a second and oppositely arranged cam P co-operating with a second pivoted arm M, the roller N on which is engageable with a terminal ramp R. The opposed arrangement of the cams ensures the operation of the mechanism at the terminal floor if the lift has not been stopped earlier.

Title: Improvements in or relating to safety devices for hydraulically operated machinery
Inventor: BALL HERBERT
IPC: F16P3/14
Filed: 1957-03-13
Abstract: 838,603. Machinery safety devices. PIONEER OILSEALING & MOULDING CO. Ltd. June 11, 1958 [March 13, 1957], No. 8220/57. Class 80 (4). A safety-arrangement for an hydraulically operated machine controlled by a valve to connect the machine either to hydraulic pressure or exhaust comprises a reversible electric motor or solenoid thrust unit M for actuating the valve under control of relays operated by photoelectric cells so that when a beam of light across an access area is interrupted the relays operate to effect movement of the valve to exhaust. Two light sources LL and LR are shown which act directly or through a system of mirrors on to photo-electric cells PCL and PCR, respectively, which control through amplifiers AL, AR, relays ALR and ARR operating switch contacts ALR1 and ARR1 in series with a main relay MR, stop switches PB3, PB4 and start switches PB1, PB2. The main relay MR actuates a holding-switch contact MR1 and motor contacts MR2, MR3. Limit switch contacts LS1 and LS2 are provided in series with contacts MR2 and MR3 and are adapted to be opened when the valve has been fully actuated to one position or the other. If the light beams are not interrupted the contacts ALR1 and ARR1 are held closed and on closure of either of start switches PB1 or PB2 the main relay MR is energized to close contacts MR1 and MR3 which results in the motor opening the control valve to the pressure supply, the motor being stopped when limit switch LS2 is opened. Any interruption of the light beams results in one or other of the contacts ALR1 or ARR1 being opened to de-energize main relay MR. This causes closing of contact MR2 to reverse the direction of the motor to open the control valve to exhaust when the limit switch LS1 opens to stop the motor.

Title: New aromatic organic diphosphines
Inventor: CHATT JOSEPH
IPC: C03C17/06
Filed: 1958-03-14
Abstract: The invention comprises o-phenylene bis-(dialkylphosphines) having the general formula:  <FORM:0859741/IV(b)/1> wherein R is an alkyl group, e.g. methyl, ethyl or isopropyl. They may be obtained by mixing an o-halolithiobenzene or a derivative thereof with a tetra-alkyldiphosphine in an inert atmosphere at a low temperature of the order of -120 DEG  C. and allowing the mixture to warm up gradually to room temperature.  An example is given for the production of o-phenylene bis (diethylphosphine) from tetraethyldiphosphine and o-chlorolithiobenzene the latter being prepared by adding a solution of butyl lithium in a mixed petrol-ether solvent to an ethereal solution of o-chlorobromobenzene in an atmosphere of nitrogen at -120 DEG  C.  The products react with metals to give coordination compounds, thus palladium, palladium black, or finely divided cobalt react with ophenylene bis-(diethylphosphine) to give coordination compounds from which the metal may be obtained in a pure state by heating (see Group II). According to the Provisional Specification a derivative of an o-halolithiobenzene may also be used to form the corresponding o-phenylene bis-(di-alkylphosphine) derivative, e.g. the 4-methyl-, 4-dimethylamino-, and 4-methoxy-o-phenylene bis (diethylphosphine) compounds.ALSO:O - Phenylene bis - (dialkylphospines) having the general formula <FORM:0859741/II/1> wherein R is an alkyl group (see Group IV(b)) react with metals to form coordination compounds from which the metal may be obtained in a pure state by heating.  Thus palladium, palladium black or finely divided cobalt obtained by reduction of cobaltous chloride react with o-phenylene bis-(diethylphosphine) in an inert atmosphere to give a co-ordination compound from which the metal may be obtained in a pure state by heating.  By carefully heating thin layers of these coordination compounds on inert materials such as glass, porcelain, silica or alumina in a non-oxidizing atmosphere mirrors whose reflecting surfaces are composed of the metal are obtained.

Abstract: 685,099. Batteries. OLDHAM & SON, Ltd. April 11, 1951 [April 11, 1950], No. 8475/51. Class 53. A ribbed separator is made of porous felted material impregnated with a thermosetting resin, the parts of the separator 12 between the ribs containing less resin than the ribs 13 which may contain sufficient resin to render them impermeable. Fig. 3 shows a machine that may be used for making the separators and which comprises a ribbed roller 15 cooperating with a heated roller 16 having notches 19 corresponding to the ribs on the roller 15 and recesses 20 between the notches. A continuous web 18 impregnated with resin is passed. between the rollers to form the ribs, the resin in the ribs being cured at the same time by the heat of the roller 16 and the pressure of the ribs 17a. The recesses 20 prevent the portions of the web between the ribs from coming into contact with the roller 16 so that the resin in these portions remains uncured. Before the web is run off the roller 16 it passes under bars 21 which keep the web in contact with the roller and ensure the complete curing of the resin in the ribs. The web on being removed from the roller 16 is run over a roll carrying a resin solution on its surface, only the tops of the ribs on the web coming into contact with the roll. An arrangement is described in which the underside of each rib also receives a coating of resin. The web is then passed through a curing oven and finally floated over the surface of a solution of a wetting agent such as turkey red oil and dried at a low temperature. The web is then cut into the required lengths to form the separators. In a modified process which is not continuous a length of web is laid on a heated flat plate having rib-forming slots and recesses as described in connection with the roller 16 in Fig. 3. Single bars are pushed into the slots or a ribbed roller is run over the web, the ribs on the roller corresponding to the slots in the plate. The web and ribs are treated with resin as in the first described process. The top and bottom edges of the separators may be reinforced with marginal bands of resin applied by two horizontal wheels. The web from which the separators are made may consist of glass and cellulose fibres, and the resins employed may be of the furfural-aldehyde, urea-aldehyde or phenolic groups.
