IPC: E04H3/04
Filed: 1921-02-17
Abstract: 180,048. Johnson, A. W. B. Feb. 17, 1921. Scales, systematic arrangements for effecting and controlling; counters.- A self-serving store comprises a plurality of compartments disposed side by side and end to end, the compartments having entrances and exits at their outer side walls, so arranged that customers after entering a compartment are obliged to walk through the compartment before passing therefrom, further exits at the rear of the compartments to permit customers to pass from the forward compartments to the rear compartments but not vice versa, and means for allowing them to pass from one side compartment to another together with paying stations at each exit or junction of exits. In one arrangement shown in Fig. 1, the store has two aisles 10, 11 provided with main entrances 12 and at each side of each aisle are compartments 13 - - 17 &c. At the forward ends of these compartments and adjacent to the main entrance 12 are entrances 29, 30, 31, 32, 37, &c. from the aisle, and at the rear of these compartments are exits 33,34,35,36,41, &c. leading back to the aisle. The rear of the compartments 14, 15, 18, 19, &c., which are disposed side by side, are connected by a lateral passage 45 and the rear of the compartments 18, 19, 22, 23 respectively by exits 46. A watching, checking, and paying station 47 is disposed at the exit 35, the entrance 39, and one of the exits 46, and also in all similar positions, and other such stations 48 are disposed at the junction of the lateral passages 45 and the exits 46. The arrangement of passageways in the compartments 13, 16, 17, 20, &c. is similar to the arrangement in the previous compartments with the exception that no lateral passage-ways 45 are necessary. The entrance, exit, and communicating passages of each of the compartments such as 30, 34, 46 are provided with turnstiles 55, 56, 57 respectively which revolve in the one desired direction only, but the lateral passages 45 are preferably provided with turnstiles enabling customers to pass in either direction. The turnstiles of the former type each have a shaft 61, secured to a base, upon which is secured a gear-wheel 63 engaged by one of the arms of a two-armed pawl 66 pivoted to the top of a drum 65 rotatably mounted on the shaft 61. Below one of the arms 67 of the turnstile is provided a cylindrical member 68 having an outer head 69 and within this member is a spring 70 which presses against the pawl and which may be adjusted to enable either of the arms of said pawl to engage the gear 63 thus permitting a reversal of the possible movement of the turnstile when desired. The goods in each compartment are exhibited on counters 59, which are preferably constructed as illustrated in Fig. 4 with a glass panel 60 at the rear of the counter, the panel dividing the counters into adjacent compartments.

Title: Improvements in or relating to the treatment of cellulosic pulp to reduce its viscosity characteristics
IPC: C08B1/00
Filed: 1943-04-07
Abstract: The viscosity of cellulosic pulp is lowered by mixing it with a dilute aqueous solution of hydrogen peroxide and warming the mixture in the presence of a metal selected from the group: iron, copper, aluminium and manganese.  As a source of cellulose in a finely-divided state, there may be employed, for example, wood pulp, cotton linters or rayon waste.  The metal may be added in the form of small pieces, fine powder, or in the form of a salt, e.g. as a chloride, sulphate or acetate.  Alternatively, the container in which the reaction takes place, e.g. a stainless steel container, may provide the necessary metal.  A dilute aqueous solution of hydrogen peroxide is prepared and heated approximately to the boiling point, the finely-divided cellulosic material is rapidly and vigorously stirred into the solution, and the pH of the mixture is adjusted to a range of between 6 and 8. The reaction, which may be effected under pressure, continues with constant agitation, and the material is finally separated and rinsed.  Examples are given in which (1) the stainless steel container provides the necessary source of metal; (2) small pieces of iron are added to the mixture; and (3) manganese sulphate is added to the mixture.  The treated cellulose is suitable for making textile coating solutions in sodium zincate, or for making cellulose xanthate solutions for the manufacture of rayon or sheets, or for making nitrocellulose.  Specification 16085/12, [Class 2 (ii)], is referred to.
Patent GB-576916-A (GB)
Title: Improved method and apparatus for polishing surfaces
IPC: B24B13/00
Filed: 1944-03-25
Abstract: 576,916. Polishing glass &c. KODAK, Ltd. March 25, 1944, No. 5570. Convention date, April 14, 1943. [Class 60] In the polishing of glass &c., especially the surfaces of optical elements, by means of a tool movable relatively to the surface to be polished and using an abrasive, for example, rouge, and a lubricant, for example, water, the lubricant is applied in small quantities whenever the polishing tool becomes too dry, the increased coefficient of friction causing the automatic actuation of a pump to supply the. lubricant. The machine shown comprises a spindle 10 reciprocated horizontally through a collar 14 by crank mechanism to move a polishing-tool 17 across the work, which is shown as a number of prisms secured in a body 15, rotated during polishing. The tool is connected to the spindle 10 by means of a channel-shaped member 18 secured to the spindle, and having adjustably pivoted therein, near one end and by two pins 20, a block 19, movement of the block being limited by a pin 30 which engages slots in the walls of the channel member 18; a post 23 extending downwardly from the block carries an adjustable ball member 24, which engages a socket 25 in the tool 17. The spindle 10 is pressed down by weights W supported by a collar 27 on the spindle, and water is supplied to the tool, through a tube 42, from a reservoir 34 carried by the spindle and having an outlet 37 leading to a valve housing 35 secured on the channel 18. The housing has therein an outlet 39 connected to a bulb 40, which lies between the block 19 and the channel 18, being compressed when the apparatus is working normally; valves 43, 44 in the housing control the operation, so that when the work becomes too dry and the coefficient of friction increases, oscillation of the block 19 about its pivot causes the bulb &c. to act as a pump. The amount of water supplied in each operation may be regulated by mounting the pin 30 adjustably in the block 19, by means of a screwed sleeve 47. A modified pumping-device comprises a housing 35, Fig. 7, in which is a plunger 56 pressed by a spring 55 to engage the inclined bottom 58 of a groove 59 in the end of the block 19, the water entering by tubing 37<1> and leaving by a tube 42<1> through a valve 57 ; both forms of pumping-device may act to allow water to flow to the work from an ordinary pressure line. In the polishing of sharply curved surfaces, a spring is attached between the free end of the block 19 and an adjusting screw carried by a bracket on the channel 18 ; for plane work and flatter curves, spring action also may be employed, two springs, namely a tension spring and a compression spring, being employed, either being operative according to the direction of torque desired upon the block 19. The positions of the tool and work shown may be reversed, the work being mounted in the tool holder 17, and the polisher in the holder 15. Specification 126,489, [Class 60], is referred to.
Patent GB-432737-A (GB)
Title: Improvements in and relating to autographic registers
IPC: B41L5/04
Filed: 1934-02-20
Abstract: 432,737. Autographic recorders. LAMSON PARAGON SUPPLY CO., Ltd., and GARWOOD, V. W., Canning Town, London. Feb. 20, 1934, No. 5603. [Class 106 (i)] In an autographic recorder of the kind in which voucher and record strips are drawn over a writing-plate 1 by feed discs 2, the lowest strip being deflected into a locked compartment 7 by a dividing plate 6, the pressure roller housing 4 is locked in the position in which the roller 3 engages the feed discs, and the dividing plate 6 is extended rearwardly beyond the pressure roller at least to the rear edge of the pressure roller housing, the arrangement being such that reloading operations may be carried out without unlocking the housing 4 thereby preventing unauthorized access to the filing compartment 7. The housing 4 and dividing plate 6 are both pivoted to the side walls of the casing and retained in the position shown by engagement with the locked lid 8 of the filing compartment. The feed discs engage the roller through shaped apertures 9 in the dividing plate, guides 14 on the underside of the dividing plate combining with the shape of the apertures to prevent the perforated leading edges of the strips from fouling the apertures. The record strip is guided downwardly into the filing compartment by a feed hook 13 of known form. To facilitate alignment of the strips during reloading, pins 15 are projected up through apertures in the writing plate by turning a handle on a shaft 16. Aligning holes in the strips are engaged with the pins and the leading edges of the strips are fed one at a time below and above the dividing plate, the slack being taken up by rotating the feed discs. When the feed blocks on the discs come into operation, the pins 15 are disengaged and the strips are fed forward together. The pins are retained in projecting position by a latch arm 20 pivoted to the supporting plate 18 for the pins, a shoulder 21 on the latch taking over a fixed plate 22. As the feed blocks near the feeding position, a pin 28 on one of the feed discs rocks a lever 25 linked to the latch, which is thus tripped and allows the pins to return to ineffective position. A second pin 29 on the disc next operates to rock the lever. 25 to a greater extent to interpose the hooked lower end of the latch beneath a stop 23 and prevent raising of the pins until the feed blocks have ceased to operate. Specification 229,616, [Class 16], is referred to.

Patent GB-908124-A (GB)
Title: Machine for screwing-in and unscrewing screws or nuts
IPC: E01B29/28
Filed: 1959-02-18
Abstract: 908,124. Screwing-up and unscrewing screws etc.; drilling. PLASSER, F., and THEURER, J. Feb. 18, 1959, No. 5643/59. Addition to 846,936. Class 83 (3). A machine for screwing-up and unscrewing screws or nuts according to the parent Specification has a modified drive by which the wrench 4 may be given a slow, powerless rotation to facilitate its engagement with a nut. The wrench-motor 2 is supplied through a line 5 by a pump 8. During idle rotation of the wrench, a branch line 9 returns some of the pressure liquid to a tank 1, through a spring- opened control-valve 10 and an adjustable bleed-valve 11. Valve 10 is connected by a rope or cable 13 to a pivoted handle 17 on the handle H of a wheel-borne chassis (not shown). Pivotal movement of handle 17, against the action of a spring-pressed plunger 16, tends to slacken cable 13 and allow the spring 12 to close valve 10. Thus, the full pressure of the pump-liquid passes to motor 2. A preferably adjustable relief valve 7 in a branch line 6 controls the maximum torque applied by the wrench, which may be replaced by a drill.

Title: Positive displacement pump
IPC: F04B1/12
Filed: 1956-02-23
Abstract: 814,135. Swash plate pumps. BENDIX AVIATION CORPORATION. Feb. 23, 1956 [March 16, 1955], No. 5693/56. Class 102(1). In a swash plate pump a rotating cylinder block 28 houses at least two pistons 24 which are actuated on their discharge stroke by a stationary, adjustable swash plate 16, the inlet and outlet to the cylinders being controlled by a stationary valve plate 30 having kidney shaped inlet and outlet ports 32 and 34 respectively. A body 40 is secured for rotation with the block 28 and is formed with a cylindrical portion 48 being closed by a concave end plug 50 forming a chamber 52 which is fed with liquid from the pump outlet through a conduit 68. Associated with each pump piston 24 is a rod 58 which acts through a spheroidal rocking member 54 on the discharge stroke of that piston to cause retraction of a second piston when the pump is starting up. A little slack is provided in the length of the rods 58 so that once the outlet pressure has been built up and hence the pressure in the chamber 52 this liquid pressure takes over the actuation of the rods 58 to the substantial exclusion of the rocking member 54. In a modified form the rocking member 54 is replaced by a spider member mounted on a spring loaded semi-spherical hub the pistons being parallel to the pump axis. In a further modification the spider member is moved away from the rods by a piston when the outlet pressure reaches a sufficient value.

Patent GB-515420-A (GB)
Title: Improvements in or relating to the production of photographically light-sensitive layers
IPC: G03C1/015
Filed: 1938-02-23
Abstract: 515,420. Photographic processes. ELVEGARD, E. R. Feb. 23, 1938, No. 5779. [Class 98 (ii)] A layer is made photographically light-sensitive by successive treatment with substances which produce silver iodide possibly together with other light-sensitive substances and then immersing the layer in a solution containing free chlorine or bromine to produce precipitates of other light-sensitive silver halides. The layer may be a cellulose foil, or gelatine, casein, dextrin or albumin applied to a base of glass or, celluloid, or a base to which the silver iodide can be caused to adhere by suitable agents. The production of silver iodide together with other light-sensitive substances can be obtained by successive treatment with solutions, the sum of the concentrations of substances in a succeeding solution expressed in gram-equivalents per litre being more than four-tenths of the corresponding sum of concentrations of substances in the previous solution with which the substances in the succeeding solution react. In one example a viscose foil is first immersed in a solution of 0.01 mol. potassium iodide in 1 litre of water, then immersed in a solution of 0.03 mol. silver nitrate in 1 litre of water to precipitate silver iodide, and then immersed in a solution containing free bromine which reacts with excess silver nitrate to precipitate silver bromide. In modifications, successive treatment solutions may be potassium iodide and potassium bromide, silver nitrate, chlorine, or potassium bromide, silver nitrate, potassium iodide, silver nitrate, bromine. The lightsensitive layer may be hypersensitized by treatment with heat, or with a solution of ammonia or an organic amine, or with a sulphurcontaining sensitizer, e.g., thiosinamine. The layer may be sensitized for regions of the spectrum other than those to which the silver salts are sensitive by treatment with cyanines or phthaleins. The layer may be dried in air or in a water-absorbing liquid, e.g., a water-soluble alcohol, ether, ketone or aldehyde. Liquid drying prevents curling, which may also be prevented by air drying if the layer is immersed in a solution of glycerine and water before drying. A dull surface may be given to the layer before treatment or after drying by grinding the surface with emery or pumice powder. The lightsensitive 'layer may be used as negative or positive film or may be fixed to a base of paper or coated on one side with a non-transparent, light-reflecting coating, e.g., white oil-paint or white cellulose lacquer. The base or coating need not be white but may have any shade, e.g., ivory or chamois. The layer may be provided, on one or both sides, with a coating impervious to moisture, e.g., a colourless, transparent nitrocellulose lacquer. One or more prepared layers may be fastened together with one or more unprepared layers of the same material or other transparent material, e.g., acetate-cellulose or nitro-cellulose. Specification 515,421 is referred to.
