Title: Improvements in and relating to shop roller blinds
IPC: E04F10/06
Filed: 1925-05-07
Abstract: 256,325. Murdoch, A. G. May 7, 1925. Window blinds, supporting- frames for.-Shop roller blinds are drawn out and supported by an arrangement of jointed pivoted arms in which a secondary arm carrying the lath, beam or the like to which the outer end of the blind is attached, is pivoted to a primary arm and moved in relation thereto by mechanical gearing operated by the movements of the primary arm about its pivot. Preferably a set of pivoted arms supports each end of the lath or beam but in light constructions a single centrally disposed set may suffice. In the arrangement shown, a tubular primary arm 10 is pivoted by means of trunnions 11 in a fixed casing 13 and carries a toothed sector 9 through which it is moved about its pivot by a manually or power operated driving pinion 8. A shaft 16 rotatably mounted in the tubular arm 10 carries at the inner end a pinion 17 which, when the arm 10 is moved, rolls on a fixed rack 18 to rotate the shaft, thereby transmitting movement through bevel gears 19, 22 to the secondary arm 20 pivoted on a pin 21 carried by the outer end of the arm 10. The articulation may be enclosed in a casing 23 which may be in sections. The shaft 16 may be carried externally to the arm 10. The Provisional Specification states that any type of gearing may be employed, such as toothed, bevel, worm, or sprocket-and-chain gearing or combinations thereof.

Title: Desalinization membrane
IPC: B01D/
Filed: 1965-03-22
Abstract: 1,056,636. Semi - permeable membranes. REGENTS OF THE UNIVERSITY OF CALIFORNIA. March 22, 1965 [March 25, 1964], No. 12029/65. Heading B5B. A semi-permeable membrane is made by casting a film from a solution containing (1) a cellulose ether or ester having anhydroglucose units of formula wherein R 1 , R 2  and R 3  are alkyl groups containing 1-8 carbon atoms or a group of formula COR 5  where R 5  is an alkyl group containing 1-7 carbon atoms, and (2) a substantially water-soluble liquid amide of formula R 6  CONR 7 R 8  in which R 6  is H, methyl or ethyl and R, and R 8  are hydrogen, methyl, ethyl or propyl; evaporating a portion of the liquid amide; immersing the cast membrane in water, and finally heating the membrane to reduce its porosity. In one embodiment the solution is made by dissolving the cellulosic derivative and the amide in an organic solvent. Alternatively, the cellulosic derivative may be dissolved in the liquid amide alone, in which case R 7  and R 8  of the amide are not both hydrogen. The casting of the solution, e.g. on. to a glass plate, and subsequent evaporation, may be carried out at -10‹ to 22-23‹ C. The immersion of the cast membrane may be effected in ice-water for e.g. 1 hour, and the subsequent heating may be carried out in water at 23-95‹ C. for e.g. 4 minutes. Specified cellulosic derivatives are acetate, acetatebutyrate, propionate or ethyl cellulose. The liquid amide may be formamide, dimethylformamide, methyl formamide or ethyl formamide. Suitable organic solvents are acetone, dioxan, tetrahydrofuran, methyl ethyl ketone, ethyl alcohol, methyl alcohol, acetic acid and formic acid. Inorganic salts may be added to the solution, or the cast membrane may be immersed in aqueous solutions of such salts. The membranes are used for recovering potable water from sea-water.

Filed: 1931-04-24
Abstract: 376,857. Copy-holders. ENGLISH, F. G. S., 42, Lavender Road, West Croydon. April 24, 1931, No. 12213. [Class 100 (iii).] In a punching machine, statistical recordcards bearing written data are fed to a reading position, the data is set up manually on a keyboard and power operated means is then actuated to punch the card according; to the data set up. The cards C are contained in a bin comprising a sloping glass top 3, sloping throat plate 2 and a removable door 4. A spring-pressed plunger 6 forces the cards upwards. A feeder 10 operated from a shaft 16 feeds the top card to the bite of rollers 1a and in this position written information on the card is read through the glass top and set up on a keyboard to actuate selecting mechanism for the punches. The card is then fed by rollers 1 to punching position and the data is punched on the card. The door 4 carries spigots 19 which are guided by an L-shaped cam. The rod 9 carrying the plunger 6 is connected to the door to allow spring 7 to urge the door closed. A spring blade 19 acts as a buffer to the door in closed position. The cards are obstructed by the throat plate and the pressure of the feeder and the plunger 6 causes the cards to snap through the throat.

Title: Improvements in refuse vehicles
IPC: B65F3/04
Filed: 1946-04-23
Abstract: 621,863. Loading and unloading refuse vehicles. HEIL CO. April 23, 1946, No. 12254. Convention date, May 18, 1945. [Class 78 (iv)] A refuse vehicle wherein refuse is loaded through an opening in the upper face of the vehicle body by a bucket which is raised to its discharging position by mechanical power means, said opening normally being closed by a movable panel adapted to effect packing and compression of the refuse, is characterised in that the panel is so connected with the bucket elevating means that it is forcibly moved to its open or closed position in accordance with the movement of said elevating means. In the embodiment shown, refuse is placed in a bucket 19 and is discharged into a container 13, pivotally mounted at 15 on a vehicle chassis 10, through an opening 27a normally closed by a panel 27 pivotally mounted on the container at 37. The bucket has a hinged cover 42 and is pivotally supported on arms 20 secured to a shaft 21. This shaft is rotated so as to move the bucket to its discharging position above the opening 27a by arms 22 rigidly secured to the shaft and connected to pistons operating in fluid-pressure cylinders 23 pivotally mounted at 24 on the container. When the arms are raised, the panel 27 is moved to the open position shown in broken lines by rods 26 and as the bucket approaches the top of the container, it is tilted to a discharge position by projections thereon engaging members 41 on the container. Side wings on the panel 27 register with the tilted bucket to prevent refuse falling outside the opening 27a. When the arms 20 are lowered and the rods 26 return the panel 27 to its closed position, ribs 271 on the panel compress the refuse in the container. Refuse is discharged from the container through a gate 28 when the container is tipped rearwardly about its pivot 15 by a piston-and-cylinder device 16. The gate 28 is pivotally suspended from hinges 29 and is provided with hooks 30 co-operating with lugs on the container, these hooks being automatically released from their locking position and the gate automatically raised by the movement of the arms 20. When the latter are raised, cables 42 connected by hooks 43 to the hooks 30 and to springs 44 secured in the arms 20, will first pivot the hooks 30 so as to unlock them and then pull the gate to its raised position. When the container is returned to its normal position and the bucket 19 lowered, the hooks 43 may be disengaged from the hooks 30 and then moved to their locking position, the springs 44 automatically retrieving the cables. The hooks 30 may be released manually from their locking position.

Title: Improved process of and apparatus for obtaining glucose from wood
IPC: C13K1/02
Filed: 1920-05-06
Abstract: 143,212. Terrisse, H., and Levy, M. May 13, 1919, [Convention date]. Glucose. - One part of wood is dried, treated with 1 to 2 parts of 35 per cent hydrochloric acid, and supersalinated with gaseous hydrochloric acid until the acid concantration reaches 41 per cent the temperature being maintained between 0 and 25 degrees C. It is then allowed to digest at a slightly higher temperature and finally the surplus acid is removed and the glucose purif.ed by washing and filtration. The acid treatment is conducted in a series of externally-cooled connected tubes A each provided with a mixer and conveyor b, liquid acid being introduced into the upper vessel and gaseous acid into the lower vessels through pipes F. The mash is digested for 5-10 hours in drums adapted to turn on hollow axes, through which water is circulated so that the temperature is maintained slightly higher than in the acid treatment. Excess hydrochloric acid is then withdrawn from the mass, which contains a mixture of glucose and dextrin, by placing the drums in communication with a vacuum vessel containing dilute acid kept at 10-15‹ C. Sufficient water is added to the mash to allow it to be filtered, and the filtrate is concentrated in vacuo to free it entirely from hydrochloric acid, which is collected in the usual manner. The dextrin may be converted into glucose by boiling for about an hour with dilute hydrochloric acid.
