Abstract: 882,925. Sawing. SPIRO ESTABLISHMENT S.A. June 11, 1958 [March 11, 1957], No. 8003/57. Class 145. Tubing fed axially, whilst rotating on its own axis, from a helical seam tube making machine is cut into lengths by a saw 3 slidable on a splined shaft 7 carried by a mounting comprising arms 10, 16 on a sleeve 18 rotable on a barrel 20, the mounting being swung to feed the saw transversely in the tubing sufficiently to penetrate the wall thickness and the saw then being carried along its splined shaft by the tubing while the cut progresses circumferentially round until complete severing takes place after a complete revolution of the tubing. The saw shaft is driven by a motor 14 through gearing 12, 11 and the feed and withdrawal of the saw is provided by a hydraulic piston 36 and a plunger 38 having a pair of rollers 40, 41 engaged in slots 42, 43 in the barrel 20 and sleeve 18, the slot 43 being sloped at 43a so that, at the end of the forward plunger movement, the sleeve 18 is rotated relatively to the barrel. The barrel is held firmly by friction liners 22 in a split bracket 23 but can yield slightly if the saw does not readily penetrate the work or if it is necessary to adjust the initial position of the saw by means of a screw 24 to suit different diameters of work. A switch engaged by the end of the work energizes the motor 14 and sets a valve to supply hydraulic pressure to the piston 36 for the in-feed of the saw and another switch operated by the collar 4 of the saw at the end of its movement along the shaft 4 resets the valve for the return stroke of the plunger, the saw being returned along its shaft by an arm 44a, and stops the motor 14. The main motor of the machine can be stopped when the saw is cutting into hard material and is started by the closure of a contact by the saw mounting when full penetration has been made. Specifications 830,504 and 830,505 are referred to.

Title: Improvements in material handling systems
IPC: B61B10/02
Filed: 1964-02-27
Abstract: 985,172. Conveyers. JERVIS B. WEBB CO. Feb. 27, 1964 [March 18, 1963], No. 8108/64. Heading B7L. A conveyer system has trucks 10 propelled along tracks 14, Figs. 1, 2, by pushers 18 on an endless chain 16 engaging abutments 12; a second endless chain 22 has groups of pushers comprising a short pusher 26 preceding a long pusher 28. To interrupt the propulsion of a truck, the main chain 16 drops out of engagement with the trucks at the line 3-3 in Fig. 1 and a short pusher 26 takes over the drive; at a further point corresponding to truck 10b, the chain 22 is lowered whereby pusher 26 is disengaged from the truck which stops until the long pusher 28 engages and moves the truck to a position 10c where the pusher 18 on the main chain 16 resumes the driving. Chain 22 is driven at twice the speed of chain 16 and in synchronism with it. In an overhead conveyer, Figs. 4, 4A, carriers 40, having two abutments 44, 45, are pushed by pushers 54 on a first chain 57 into a position where a short pusher 50 on a chain 48 engages abutment 44, pusher 50 being the leading pusher of a group comprising also two long pushers 51, 52. The track 46 carrying chain 48 rises at 60 to disengage pusher 50 from abutment 44 and engage pusher 51 with abutment 45. The track 46 again rises at 62, Fig. 4A, over a section shorter than the truck wherein pusher 51 disengages from abutment 45 and then engages abutment 44. Each carrier 40 is now to be driven by pushers 67 on a chain running on track 66, Fig. 5A; pusher 51 leaves abutment 44 and pusher 52 engages abutment 45 to push the carrier into a position where a pusher 67 can engage abutment 44. The chains are all driven in synchronism. The carrier is halted twice during its passage adjacent chain 48.

Abstract: 633,638. Control systems for consumption apparatus. BENDIX AVIATION CORPORATION. March 26, 1947, No. 8255. Convention date, April 25, 1946. [Class 38 (iv)] [Also in Group XXXVII] Switching control.-In a switching system, a pressure-operated switch opening and closing at different pressures and suitable for use in aircraft, comprises an evacuated capsule 13 mounted in a sealed casing 11 connected at 20 to an air pipe-line. A solenoid 12 also mounted in the casing has a core 47 returned by a spring 48 so as to compress a weaker spring 55 situated between the capsule 13 and a collar 53 screwed on to the end of the core 47. As the air pressure falls, the capsule expands against the spring 55 and a contact 60 on the capsule engages an adjustable pointed contact 28 to close the solenoid circuit. The core 47 then moves to the right causing a contact 51 carried by it to disengage contacts 42 controlling a load 67 and engage contacts 40 controlling a load 68, this movement also relieving the compression of the spring 55 on the capsule 13. Separation of the contacts 28, 60 to de-energize the solenoid and return the contact 51 cannot now take place until the pressure rises above that at which the solenoid was energized, since during the expansion of the capsule to energize the solenoid the force of spring 55 had to be overcome and thus the air pressure required was less than would have been necessary had there been no spring.

Patent GB-356776-A (GB)
Title: Cellulose derivatives and process for making same
IPC: C08B11/00
Filed: 1930-03-14
Abstract: Cellulose ethers are obtained by acting upon cellulose in presence of a basic substance particularly caustic alkali, with a halogenolefine. Bleached or unbleached wood pulp or cotton linters, or other substance containing cellulose, or cellulose conversion products may be employed as starting material, and the p  halogenolefine may be used in undiluted or diluted state.  Any body of the cellulose group which has been proposed for the production of viscose or of ammoniacal copper-oxide cellulose may be employed.  Examples of such substances are cellulose hydrated or hydrolysed by mercerization with subsequent washing, or by the action of a strong mineral acid, or by treating with a weak mineral acid, or by treatment with zinc halide, or cellulose which has been ground in the presence of water, or oxycellulose insoluble in alkali.  In an example, finely divided wood pulp or cotton linters is mixed with caustic soda in a kneading or shredding machine, or is impregnated with caustic soda the excess of which is pressed out.  The alkali cellulose is placed in a rotating autoclave and trichlorethylene is added.  The mixture is then heated in the autoclave for several hours.  The product is washed till free from alkali and dried, or it may be dissolved in caustic alkali solution.  The crude product may be purified by dissolving in dilute caustic soda, any insoluble matter being removed by filtering, straining or centrifuging.  The solution is treated with dilute sulphuric acid or acetic acid in order to precipitate the product, which is separated from the mother liquor by filtering, washed free from acid, and dried.  The product is a white powder insoluble in water and organic solvents, but soluble in dilute alkali. Transparent films are obtained by spreading the solution on a glass plate and coagulating with dilute acid. Instead of trichlorethylene, acetylenedichloride (sym. dichlorethylene) or monochlorethylene (vinyl chloride) may be employed.  Instead of the chlorine derivatives, the corresponding bromine or iodine derivatives may be used.  The process may also be carried out in the presence of a catalyst such as a salt of copper, iron, or nickel.  The products may be employed in the manufacture of artificial silk, films, plates, plastic substances, coatings, fabric dressings, sizes, thickening agents for textile printing, fixing agents for pigments, binding material, and book cloth.

Filed: 1941-07-02
Abstract: 549,779. Thermally-actuated valves. KLEEN, N., E.. Af. July 2, 1941, No. 8334. Convention date, July 2, 1940. [Class 135] [Also in Groups XIII and XXXVII] In dual reversing absorption refrigerating systems working out of phase to produce continuous refrigeration, heat exchange is effected between the hot and cold generator-absorber vessels during a pause in the changing-cover action effecting the supply of heat to one generatorabsorber vessel and of cooling-medium to the other: The. evaporating- condensing cooling- medium in the jackets 14, 14a; Fig 2, of the generator-absorber vessels 10, 10a is condensed in elements 15, 15a and led to a common collector vessel 16 and thence to a valve chamber 17, and the valves 20, 20a in this chamber are actuated by a lever 22 under impulses from bellows 30, 30a connected with thermostats 31, 31a on the generator-absorber vessels. The bellows rods 32, 32a alternately engage the lever 22, which is pivoted at 23 to the cap of a packing bellows 24, and which carries contacts to engage fixed contacts 28, 28a, in the circuits of the generator heating elements 13, 13a. In an intermediate position of each thermostatic bellows a pivoted rod 36 is engaged by a plate 46 on the bellows rod to position a stop arm 42 in the path of the contact end of lever 22 to hold it and thereby also the valves in intermediate positions, in which, cooling medium in the hot jacket communicates with that in the cold jacket, while the heat supply is cut off from both generators. As the temperature in the. previously hot generator vessel sinks, its thermostat withdraws the stop from the switch lever, which then completes its movement to establish the heat supply to the previously cold generator and reverse the valves in the cooling system. In one modification the bellows, which engages the valve-switch lever to reverse it also positions the stop to hold the lever, temporarily in neutral position, and then releases the stop to allow the lever to swing, completely over. In. the arrangement shown in Fig. 8 two pairs, of valves 67, 68 and' 71, 72 are employed, the upper pair controlling communication between supplementary conduits 69, 70 in the cooling circuits. The valve body is slidable on guides 66, and a further valve 73 on the body slides across the top of the valve chamber to control the flow of condensed cooling medium thereto from the collector vessel 16. A similar construction is described in which an upper pair of valves controls the cooling medium circuit through additional jackets around the generatorabsorber jackets. In the system shown in Fig. 9, the main valves 20, 20a and the switch lever are controlled by thermostatic bellows 30, 30a for a complete change over without a pause, while lift valves 77, 78 controlling branch conduits 83, 84 are actuated by separate thermostats 76, 76a to provide heat interchange during a period in which the heating circuits are interrupted by mercury switches 90, 91 carried on the rods of the, lift valves.
