Title: Improvements in autographic registers
IPC: B41L5/04
Filed: 1923-03-15
Abstract: 219,048. Imray, O. Y., (American Sales Book Co., Ltd.). March 15, 1923. Memorandum appliances.-In an autographic register in which superposed record strips are fed forward' by a pair of feed rollers and are aligned by means of pins reciprocated across the path of the strips and engaging registering apertures therein, the pins are carried on a vertically reciprocated member operated independently of the feed rollers and dividing the container 1 into a roll-holding chamber and a filing chamber. The strips are fed by positively geared rollers 31, 36 from rolls held by side springs in brackets 93 in a roll-holding chamber and pass over a writing table 8 where carbon strips are interposed between them. The ends of the roller 36 are mounted in two vertically slidable plates 39 spring-pressed towards the roller 31. A hand'c 32 is provided to rotate the rollers to feed the strips, a pawl 34 engaging ratchet teeth 33 to prevent any backward movement. Two guide openings 56, 57 are formed, adjacent to the delivery side of the feed rollers, by crossbars 52, 56 and a central guide plate 50 carried bv side plates 51 pivoted at 49. The lowest strip is led through the opening 57 into a filing chamber where it is supported by a spring member prior to filling, the other strips passing through the opening 56 out of the machine. A second handle 23 serves to operate, through a crank 24, a vertically reciprocating member 16 which divides the container 1 into a roll-holding chamber and a filing chamber The member 16 carries aligning pins 100, a filing pin 73 and a knife 58, the latter co-operating with the bar 52 when the member 16 is raised, to sever the strips after these have been fed an amount indicated by spaced marks on the uppermost strip. At the same time, the pins 100 enter registering apertures in the strips and the roller 36 is lifted by parts 105 on the member 16 engaging the plates 39, so that the backward pull on the strips enables the pins to align the strips. A sliding plate 55, mounted between the side plates 51 and forming part of the guide plate 50, is moved to the right, Fig. 3, so as to permit the knife 58 to pass upwardly, by means of a rock shaft 62 having two projections 66, 63 the first being engaged by the knife on its upward movement to turn the shaft 62 and the second engaging slots in the plate 55 to move it. The side plaes 51 are adjustable about their pivotal axis 49, so as to adjust the bar 52 relatively to the knife 58 by means of a member 85 engaging a slot in the bottom of the plate 50 and adapted to be moved on a pivoted block 80 by screws 89. A spring 90 engaging the block 80 holds the arm 83 in engagement with the plate 50. The roller 36 may, if desired, be lifted by turning a handle on a shaft 46 having cam surfaces engaging the lower edges of the plates 39. Carbon papers, arrangement of.-A trough is provided at one side of the table 8 to hold a roll of carbon papers, the papers being clamped at the other side by a bar 11 pivoted at 14 and bevelled at the end to engage a notch 13.

Abstract: 759,790. Batteries. SOC. DES ACCUMULATEURS FIXES ET DE TRACTION. March 16, 1954 [March 17, 1953; Feb. 18, 1954], No. 7595/54. Class 53. [Also in Group XXII] Battery electrodes are made by a continuous process from a perforated metal strip 4 which may consist of a perforated band or a length of wire mesh made of nickel, copper or iron which may be plated with nickel, zinc, cadmium or other metal. As shown in Fig. 1, the band may be provided with an unperforated edge 1 from which the electrode lugs may be formed and with unperforated strips 3 along which the band is eventually cut to form individual electrodes. The band is coated on both sides with finely divided electrochemically active metals in crystalline form, such as cadmium, zinc, iron, nickel, silver, lead, tin, which are applied by passing the band from a drum 5 through a suspension 7 of the metal in a viscous liquid which may consist of an aqueous solution of an alginate, gelatine, starch, or salts of carboxymethyl cellulose or other cellulose derivatives. The coated band passes through an adjustable slot 9 to regulate the thickness of the coating and then between rollers 10 and through a drying chamber 12 to which hydrogen, carbon dioxide, nitrogen or other inert or reducing gas is supplied through a pipe 14. The dried band is compressed by rollers 15 and wound on a drum 16. Finely-divided crystalline cadmium for the process may be prepared by the action of powdered aluminium or zinc on solutions of cadmium salts or by the electrolysis of cadmium chloride or sulphate solution. Mixtures of cadmium with iron or nickel may be obtained by the electrolysis of mixed solutions. Crystalline zinc may be prepared by the electrolysis of zinc chloride or sulphate or of alkaline solutions of sodium or potassium zincate. The zinc may also be obtained by applying a jet of air to a thread of molten zinc issuing from a hole in the containing vessel. Specifications 687,569, 759,788 and 759,789 are referred to.

Title: Internal combustion engine installations for vehicles or vessels
IPC: F02D29/00
Filed: 1957-03-07
Abstract: 861,681. Fluid-pressure servomotor-control systems. SULZER FRERES S.A. March 7, 1957 [Sept. 14, 1956], No. 7662/57. Class 135. [Also in Group XXVII] In an engine 1 driving through a torque converter 2 which is adjusted so that as engine speed falls the torque on the engine is reduced and vice versa, a changeover device overrides the torque adjusting device during idling to reduce the torque to a minimum value. As shown the torque converter 2 comprises a main electric generator driving traction motors and the torque is adjusted by a variable resistance 32 in the generator excitation circuit. The fuel injection pumps are controlled by a governor 6 through a servomotor 10 which also controls the torque adjusting means 32 through links 41 . . . 38 connected to the control valve 34 of a vane type servomotor 33. The governor loading spring 28 is controlled by a servomotor 26 having a control valve 25 connected to a spring-loaded diaphragm 21 whose position is varied by a control member 19 controlling a reducing valve in a compressed air pipe 18. The feed-back lever 24 connecting diaphragm 21 to the valve 25 and servomotor piston 26 is extended at 24<SP>1</SP> and forms the overriding device for the torqueadjusting means being connected by links 47, 49 and 55 to the torque control valve 34. When the control 19 is set at a point in the power range 1 . . . 10 on the indicator 52, the diaphragm 21 is loaded by a predetermined air pressure to set the governor to a predetermined engine speed, any reduction in which causes the governor to move piston 10 upwards to increase the fuel supply and simultaneously through links 41 . . . 38 to reduce the torque so that the engine speed is restored to the governed value. When the control 19 is just above the idling point 1 the piston 26 is stationary against a stop 50, thereby reducing the fuel supply to minimum and tending to set the torque adjusting device to maximum torque. During final movement of the control 19 to the idling point 1, the lever 24 pivots about the pivot 53 to override the normal torque adjusting linkage 41 . . . 38 and set the torque adjusting means 32 to minimum torque whereby subsequent acceleration of the engine is facilitated. During movement of the control 19 from point 1 to 0, the traction motors are disconnected from the generator 2, leaving the engine driving a subsidiary generator 3 which provides power for the engine accessories. The lever 40 is divided at its pivot 43, the two parts 39, 40 being connected by a spring 42 which permits the part 39 to be arrested by a stop 44 before the piston 10 has reached the minimum fuel position, temporarily preventing movement of the torqueadjusting device 32 in the maximum torque direction. Rapid unloading of the traction motors, e.g. if the driving-wheels slip during acceleration, is obtained by energization of an electromagnet 54 which temporarily lowers the valve 34. The fluid-pressure servomotors may be replaced by similar electrical means and the torque converter may comprise an hydraulic coupling.

Abstract: 569,072. Paper pulp beating-engines. PAPIERFABRIK CHAM AKT.-GES. May 17, 1943, No. 7789. Convention date. May 7, 1942. [Class 96] In a paper pulp beating-engine of the kind having a pivoted bed-plate 3 above the roll 2, the fibrous material, e.g. wood pulp, waste paper, leather, or leaves, &c. is treated initially by raising the bed-plate 3, lowering a pivoted wall 5 and rotating the roll 2 in the direction indicated, i.e. oppositely to the normal direction, as the fibrous material is being introduced, so that it is thrown by centrifugal force against the wall 5, which deflects it into a channel 8 for re-circulation to the roll 2. Water-sprays 7 from pipes in the wall 5 prevent the-fibrous material lodging behind the wall. For the subsequent beating, the wall 5 is raised and the water cut off, by a servomotor 9 actuated in accordance with the direction of rotation of the roll 2.

Title: An improved pigment dispersion for water thinnable paints
IPC: C09B67/20
Filed: 1965-02-23
Abstract: A pigment dispersion for blending with water thinnable paints comprises a water-soluble hydroxyalkyl cellulose or a water-soluble partially saponified polyvinyl acetate, or a water-soluble partially etherified derivative of such a partially saponified polyvinyl acetate or of a polyvinyl alcohol, the proportion of the water-soluble ingredient in the dispersion with respect to the pigment in the dispersion being at least 5% by weight.  The hydroxyalkyl cellulose may be a water-soluble hydroxyethyl cellulose. The polyvinyl alcohol derivative may be a partially saponified polyvinyl acetate, particularly one which is 80 to 90% saponified, or a partially or completely saponified polyvinyl acetate which has been partly etherified with a lowr alkylene oxide such as ethylene oxide. The dispersion may be prepared by dispersing a dry pigment in the aqueous solution of hydroxyalkyl cellulose or of a water-soluble partially saponified polyvinyl acetate, or of a water-soluble partially etherified derivative of same or of a polyvinyl alcohol or by mixing together a conventional dispersion of a pigment in an aqueous dispersion medium and the above aqueous solution, in any case the proportion of hydroxyalkyl cellulose &c. being 5 to 30% by weight of the pigment.  In an example, to 40 parts of aqueous dispersions of pigments are added 50 parts of 5% aqueous solutions of hydroxyethyl cellulose, 5 parts of diethylene glycol and 5 parts of 10% polyoxyethylene nonyl phenol ether. 2.5 parts of the mixture are added to 100 part lots of white emulsion paints of the usual commercial polyvinylacetate, polyacrylic and polystyrene-butadiene types.

Title: A process for producing lubricating oil or additions to lubricating oil
IPC: C10M101/02
Filed: 1937-03-17
Abstract: Viscous oils of high viscosity index, used as lubricants or additions to lubricating oils, are obtained by polymerizing gaseous alkenes at increased pressures and at temperatures above 125 DEG  C. to products containing large proportions of gasoline, removing the gasoline, and then further polymerizing the residue in presence of a catalyst at temperatures below 125 DEG  C. and at pressures lower than those used in the first stage.  The product may be refined, e.g. by hydrogenation, sulphuric acid, or bleaching earth.  Alkenes specified are propene, butenes, mixtures thereof, and gas mixtures containing them as the larger part of the unsaturated constituents, e.g. gases obtained by cracking paraffin wax or mineral oils or residues.  The polymerization of the higher-boiling fraction may take place in presence of benzene, naphthalene, or mineral oils rich in aromatics. Suitable catalysts are aluminium chloride and boron fluoride. Catalysts are preferably present in the first polymerization; phosphoric acid, sulphuric acid, benzene-sulphonic acid, bleaching earth, and floridine are suitable.  Both polymerizations may be in stages. In an example, cracking gas is passed over a phosphoric acid-kieselguhr catalyst at 200--250 DEG  C. and 10--15 atmos. until 90 per cent of the olefines is converted; the product is distilled to 180 DEG  C., 87,5 per cent passing over as a high anti-knock gasoline; the residue is polymerized at 100 DEG  C. and atmospheric pressure for 5 hours in presence of 4 per cent of aluminium chloride.ALSO:Viscous oils of high viscosity index, used as lubricants or additions to lubricating oils, are obtained by polymerizing gaseous olefines at raised pressures and at temperatures above 125 DEG  C. to products consisting largely of gasolene, removing the gasolene, and further polymerizing the residue in presence of a catalyst at lower pressures and at temperatures below 125 DEG  C.

Title: Reinforced latex foam rubber sponge
IPC: C08J9/00
Filed: 1954-03-18
Abstract: In a method of making a sponge material comprising frothing natural or synthetic rubber latex, a thermo-setting phenol-aldehyde resin is incorporated in the latex before, during, or after frothing of the latter.  In an example, 50 parts natural rubber latex and 50 parts of GR-S synthetic rubber latex are mixed with rosin soap, potassium oleate, alkylated phenol emulsion as antioxidant, sulphur, zinc mercapto-benzothiazyl, and butyl zimate, and frothed.  To the froth is then added zinc oxide, 3 or 5 parts of an aqueous solution of a partially condensed resorcinol-formaldehyde resin, and sodium silicofluoride. Alternatively a resorcinol-formaldehyde resin is formed within the foam by adding aqueous solutions of resorcinol and hexamethylene tetramine or paraformaldehyde after the addition of zinc oxide. The water soluble resorcinol-formaldehyde resin may be prepared by dissolving resorcinol in formaldehyde in the presence of water, adding a trace of ferric chloride and then an aqueous solution of sodium hydroxide.  An inert filler, such as clay, titanium dioxide, or ferric oxide may be incorporated in the mix to be frothed.  The frothed mix is gelled by adding sodium silicofluoride and subjecting to the action of high-frequency alternating currents. The frothed latex does not tend to flow and may be shaped, e.g. so as to have a fluted surface, prior to gelation.  The vulcanized sponge also has the property that it may easily be provided with a surface design by the application of a heated design forming means.ALSO:In a method of making a sponge material comprising frothing natural or synthetic rubber latex, a thermo-setting phenol-aldehyde resin is incorporated in the latex before, during, or after frothing of the latex.
