Title: Improvements relating to slicing machines
IPC: B26D7/32
Filed: 1927-08-22
Abstract: 288,960. U. S. Slicing Machine Co., (Assignees of Stiles, E. M.). April 16, 1927, [Convention date]. Cutting slices in succession.-In a slicing-machine, a contact member is adapted to move across the slices as they are being sliced so that the slices will be straightened and deposited in a neat stack on the slice receiver. The invention is described as applied to a machine having an oscillating slice receiver comprising a plate 21 which is fed downwards intermittently as described in Specification 282,871. A roller 27 is carried on a spindle 28 supported by a bracket 29 mounted in a socket 30 attached to the outer surface of the wall 25 of the slice receiver. The position of the roller may be adjusted by rotating the bracket in the socket, by moving it up and down therein, and by means of a joint 31 in the bracket. The arrangement is such tha.t the roller passes the cutting edge of the knife 12 somewhat later than the front side of the material being sliced, and, as the receiver moves forward faster than the carriage of the machine, the roller slides along the slice, which is deflected by a deflector 26, and tends to keep it strstohed. The roller moves past the front edge of the slice just before the rear of the slice is severed. The roller may be omitted or may be replaced by a plate.

Title: Improvements in the hydrogenation of coal
IPC: C10G1/06
Filed: 1929-07-18
Abstract: 337,028. Imperial Chemical Industries, Ltd., Holroyd, R., and Cockram, C. July 18, 1929. Hydrogenation, destructive.-In a multi-stage process for destructive hydrogenation of bituminous coal, the coal is first treated with or without hydrogen, at or just above the temperature of initial thermal decomposition at which the ulmic constituents disintegrate. This heating may be effected in vacuo or in an inert gas or with hydrogen with or without oil or catalysts. In the preferred process hydrogen is used at 250 atmos. pheres in the presence of high temperature tar or oils derived from a later stage, and in the presence of massive catalysts, e.g. ribbon, foil, tin plate or mixed catalysts. Sufficient hydrogen is used to de-oxygenate the coal and yield a fusible product. The product is further hydrogenated, e.g. by treating with hydrogen with or without catalysts and at a higher temperature, and the hydrogen may be diluted with gaseous hydrocarbons, carbon monoxide, nitrogen, coke oven gas, " cracked gas," &c. Fluid products may be fractionated to obtain petrols, the heavy oils being further hydrogenated or returned to the process, In an example, Bentley coal mixed with oil from a later stage is treated with hydrogen at 50 atmospheres and at 390‹ C. (within 5‹ or 10‹) in the presence of sheet iron coated with tin. Water is formed with little or no gas, and the residue is a pitch-like material soluble in chloroform. About 4 per cent of hydrogen is taken up. The product is treated with hydrogen at 250 atmospheres and at 460-470‹ C. for 1 hour with the same catalyst, yielding petrol, middle oil and heavy oil. Part of the heavy oil is used in the first stage, while the remainder and the middle oils are hydrogenated. In another example the gas used in the second stage is hydrogen containing up to 15 per cent of methane. Specification 344,975, [Group III], is referred to.

Title: Electric timing system, particularly applicable in television
IPC: H04N5/073
Filed: 1939-07-29
Abstract: 531,712. Television ; valve generating circuits ; impedance networks. HAZELTINE CORPORATION. July 29, 1939, No. 22093. Convention date, Aug. 26, 1938. [Classes 40 (iii) and 40 (v)] An electrical timing system for deriving from a given timing pulse a second timing pulse having a predetermined time delay comprises a wave-filter having a mis-matched termination so that the initial pulse is reflected and produces at the input terminals a second pulse having the same or opposite polarity to the initial pulse, according as the filter is terminated by an open circuit or by a short circuit. At the input end, the filter terminates in an impedance-matching m-derived section L 1 , L 2 , C 2  which matches the image impedance of the filter to the resistance R, and so prevents further reflections of the pulse. The initial and reflected impulses a, b, Fig. 2b, of opposite polarity may be used to produce the wave-form shown in Fig. 3 by associating the input end of the filter with two valves 15, 16, the initial impulse causing valve 15 to charge condenser 13, which remains charged until valve 16 short-circuits it on the receipt of the reflected impulse of opposite polarity. By making the delay due to the filter equal to the width of the initial impulse, or to half the interval between impulses, complex impulse trains comprising line synchronizing impulses, equalizing impulses, and frame impulses may be obtained, Fig. 4 (not shown). Line and frame synchronizing signals differing in duration may be separated by passing all the impulses to such a filter circuit and arranging that the reflected long frame signals overlap the initial signals so as to double their amplitude, whereas the reflected short line signals do not overlap, Fig. 5, not shown. Specification 514,271 is referred to.

Title: Improvements in or relating to the manufacture of cellulose
IPC: D21C5/00
Filed: 1937-08-16
Abstract: Cellulose for explosives or artificial silk, e.g. viscose, is obtained from the stalks and/or leaves of annual plants such as maize or the common cane or reed (Arunds Donax) by five successive treatments, first of an acid nature, e.g. a bisulphite liquor, second of an alkaline nature, e.g. sodium hydroxide and sodium sulphide solution, third of an oxidizing nature in presence of acid, e.g. chlorine water, fourth of an alkaline nature, e.g. caustic soda solution and fifth of an oxidizing nature in presence of alkali, e.g. calcium or sodium hypochlorite solution, the first two treatments being effected in the presence of sugars, e.g. of 5 or 6 carbon atoms/molecule which protect the cellulose against secondary reactions.  The used alkaline lye recovered by pressing after the second treatment contains sugars, and after acidification with SO2 forms a bisulphite solution suitable for use in the first stage of the process.  In an example cane cut into pieces 2-4 cms. long is heated indirectly with steam during 3 hours to a temperature of 125 DEG  C. in a solution containing H2SO3, alkaline or alkaline earth oxide, and sugars. The temperature is then raised and maintained at 130-135 DEG  C. for a further 6 hours.  The cooked material is disintegrated in a pulping engine washed and heated for 30 minutes at 120 DEG  C. in a solution containing NaOH and Na2S.  The alkaline solution is recovered by pressing the material.  The cellulose is treated at 22-24 DEG  C. in dilute chlorine water, washed first with water then with dilute caustic soda solution at 45-50 DEG  C., and then again with water and then treated with dilute sodium or calcium hypochlorite solution.  After a final washing the cellulose is converted to sheet form.

Abstract: 1,062,205. Fluid powered guns. DAISY MANUFACTURING CO. May 27, 1965 [June 30, 1964], No. 22639/65. Heading F3C. A fluid powered gun comprises a barrel 12 which is supported at one end in a frame 32. The frame 32 houses a valve assembly 36, 70, the part or plunger 36 being spring urged into engagement with the part 70 which is supported by a valve shaft 72 slidable in a packing nut 76 of the frame 32. The plunger 36 at its forward end co-operates with a projectile elevator 44 spring loaded against upward movement in the frame 32. The elevator 44 has two positions, the lower one, as shown in Fig. 2, wherein a recess 60 in the elevator is loaded with a projectile from a feed tube 118 by a spring-loaded plunger 120 and an upper one to which it is biased by actuation of the trigger 14 to bring the projectile into line with the bore of the barrel 12. A passageway 64 is provided in the elevator 44 connecting with the recess 60 and, adjacent the passageway 64, an inclined surface 56 is formed against which the plunger 36.is urged by fluid pressure in a chamber 66. The fluid passes from a container 20. and through a hollow needle 68 to the chamber 66. On upward movement of the elevator 44 and associated inclined surface 56, the valve assembly 36, 70 moves forwardly until a flange 80 on the shaft 72 abuts the nut 74 when the valve assembly opens to allow pressurized fluid to pass through a longitudinal bore in plunger 36 to propel the projectile outwardly through the barrel. The parts of the valve assembly then travel back to their inoperative positions. The feed mechanism of the gun comprises a channel on one side of the gun, a projectile storage area located about the inner end of the barrel and a further channel to the feed tube 118 (Figs. 3, 4, not shown). When the feed tube 118 is empty the plunger 120 engages in the recess 60 to prevent further actuation of the gun until more projectiles are introduced into the feed tube 118 by retracting the plunger 120 by means of a manual operator 124 (Fig. 3, not shown), and pointing the gun upwardly such that projectiles are fed by gravity from the projectile storage area and further channel.
