Abstract: 311,325. Waggonfabrik Geb. Gastell Ges. May 9, 1928, [Convention date]. Drawing-appliances.-A device for tracing on one surface of a workpiece, such as a wooden plank, a reproduction of a line &c. on the other surface, comprises two arms one carrying a tracing point and the other a pencil &c., the arms being connected together as by a pivot and being adapted to be passed one over each surface of the plank &c. so that the tracing point and the pencil &c. can be moved in unison over the said surfaces. In the form shown the arms 1, 2 are connected by a pivot 3 and are extended beyond the pivot to form handles 4. The arm 1 is provided at its outer end with a member 5 which rests on the workpiece and prevents tilting of the arm, this member carrying supports 9, 10, 11 for a sleeve 8 in which the tracing point 6 is adjustably mounted. The arm 2 carries at its outer end a bush 12 in which is adjustably mounted a sleeve 13 carrying the pencil &c. 7 which can be adjusted within the sleeve by a rod 16. The arrangement is such that the pencil 7 is in line with the tracer 6. The pencil is preferably acted upon by a spring within the sleeve 13 so that it can be withdrawn from engagement with the workpiece to enable the device to be moved to a fresh position. The means for withdrawing the pencil may consist of a finger piece mounted near the handle and acting through a lever or cord and pulley device. Alternatively a spring may be disposed between the handles 4 so that the members 6, 7 move apart when the pressure on the handles is removed. In another form the arms 1, 2 are rigidly connected together and each of the members 6, 7 is resiliently mounted in its support.

Title: A method of and apparatus for treating hydrocarbons for the production of lighter hydrocarbons
IPC: C10G9/40
Filed: 1919-05-27
Abstract: 141,223. Andrews, B., and Averill, W. C. May 27, 1919. Hydrocarbons, cracking; evaporating by contact with hot liquid.-In converting hydrocarbons into lighter hydrocarbons, the oil is injected into tubes containing molten metal in such manner that the molten metal and the vapours of the oil circulate together through the tubes. The operation is preferably conducted under pressure. A pressure of 75 lb. and a. temperature of 500‹ C. are used in treating a distillate of 32‹ BÚ. In one form of apparatus, Fig. 3, the cracking-tubes 3 are U-shaped and open into a header 2. Supply pipes 4 lead oil into the lower part of one leg of each of the tubes 3. The oil vaporizes when it issues from the pipe 4, and the vapours rise and set up a circulation of the molten lead or other metal in the tubes 3. The tubes 3 are heated by a furnace 1, Fig. 1. The vapours pass through a pipe 8 to a dephlegmator 7, where the heavier constituents are removed. The light hydrocarbons are condensed in a cooler 10. The pressure is regulated by a throttle valve 15 at the exit from the cooler 10, and a supply of steam may be admitted to the dephlegmator by a pipe 14 in order to maintain the pressure. The form of apparatus shown in Fig. 5 consists of an outer downflow tube 3 and an inner upflow tube 5, to the lower end of which oil is admitted by a pipe 7<a>. The oil is preheated bv passage through a pipe 7 in the furnace flue. The metal and the vapours escape by openings 6 at the top of the inner tube, and the vapours are led to a chamber 11 in which any carbon is allowed to deposit. A pressure of 50 lb., due to the weight of the metal, may be obtained at the base of the cracking-tubes when tubes 10 ft. long are used.

Title: Improvements in or relating to the Storing of Gases under Pressure.
IPC: C10L3/04
Filed: 1916-09-26
Abstract: 106,406. Acetylene Illuminating Co., and Stephenson, A. Sept. 26, 1916. Dissolving acetylene.-Acetylene is supplied to a receptacle containing a solvent, such as acetone, and subjected to a temperature considerably below the normal by connecting the receptacle to a compressor, pump, accumulator &c. adapted to supply the acetylene at a pressure equal to or greater than the ultimate pressure desired or allowed; the acetylene may be supplied at a pressure which with the low temperature serves to liquify it. As shown, acetylene from a source of supply A is forced by a pump &c. C through a pipe b into a cylinder B, which is placed in a chamber D containing a cooling-medium connected to refrigerating-apparatus E. The acetylene may be cooled prior to its entry into the cylinder by making the pipe b pass through the chamber D, as indicated in dotted lines, or otherwise. In another form, the cylinder is placed in an inner chamber connected to the pipe b, the pressure and temperature not being such as to liquefy the acetylene. The expansion coils of the refrigerating-apparatus may, in another form, be arranged within the chamber D which contains a circulating brine solution in contact with the cylinder, or the expansion coils may be arranged in a chamber containing the cylinder and connected to the pipe b. The acetylene may be supplied primarily to an accumulator chamber containing the solvent and subjected to the low temperature. In a. modified method, the refrigerating-plant is used only for liquefying the acetylene and the cylinder with its solvent is cooled by the conversion of the liquid into gas, the refrigeration being effected, if desired, by cooling the gas by expansion of a part thereof. If the refrigeration is carried out in stages, the early stages may be employed in refrigerating the cylinder and its contents and, if desired, the supply pipe and the final stages employed for liquefying the acetylene, or conversely. A suitable separator may be used to extract from the refrigerated gas, prior to its entry into the cylinder, impurities of higher boiling point, such as moisture or ammonia.

Title: Improvements in or relating to clutch and gear operating mechanism for motor vehicles
Filed: 1936-05-15
Abstract: 472,190. Clutch and gear operating mechanism. BENDIX, Ltd., and IRVING, J. S. May 15, 1936, No. 13739. [Class 80 (ii)] The main clutch and the gear-changing mechanism upon a motor-vehicle are operated by a vacuum or pressure servomotor which disengages the clutch fully before it starts to effect the gear change. After a new speed ratio has been selected by suitable means (not shown), a button n is pressed which opens a valve c connecting a servo cylinder a to engine suction. The piston-rod d of this cylinder is coupled to a balance lever f at a point e adjacent the lever end x which is connected to a clutch disengaging lever h and rock-shaft j. The servo stroke thus pulls the shaft j anticlockwise, so opening the clutch (not shown), which opening is finished by the time the lever h comes hard against a stop 18. The servo stroke continuing pulls the other end w of the balance lever f left and through a link k rocks shaft m which through suitable means effects the change preselected. A spring r allows the lever end w to go on far enough to strike a button p which allows the valve c to close so that the servo piston and shafts j, m are returned to their first positions by return springs (not shown). There is described with reference to Fig. 2 (not shown) a lost-motion arrangement by which, in the event of failure of the servo action, the operations are effected in the same sequence by manual effort on the clutch pedal.

Title: A process for producing trithiones
Inventor: HODGSON RUSSELL LINDSAY
IPC: F16L55/052
Filed: 1966-03-29
Abstract: 1,2Dithiole-3-thiones (trithiones) of the general formula <FORM:1069308/C2/1> wherein R and R1 are independently a hydrogen atom or hydrocarbyl group are prepared by reacting compounds of the general formulae RHC = CR1CH3, RH2C-CR1 = CH2 or RH2C -CHR1-CH3, where R and R1 are as defined above and may be or comprise aliphatic hydrocarbon groups capable of reacting with sulphur to form trithione groups, with elemental sulphur in the vapour phase at 450 DEG -575 DEG  C. The hydrocarbon reactant preferably has from 3 to 14 carbon atoms, and comprises at least one chain of at least 3 carbon atoms at least one of which occupies a terminal position and carries 3 hydrogen atoms whilst none of the three carbon atoms is linked to more than one hydrocarbyl substituent.  The substituents are preferably distributed so that the reactant as a whole does not contain any aliphatic chain of over 3 carbon atoms wherein each carbon atom carries at least one hydrogen atom.  Two aliphatic chains of 3 carbon atoms may have a phenyl substituent in common as in diisopropylbenzene.  The sulphur can be prepared in situ from H2S and SO2 in a reactor which is preferably packed with an inert material at 400 DEG -450 DEG  C. the H2S and SO2 being introduced in a preferred molar ratio of approximately 2: 1; elemental sulphur can also be used. The ratio of the number of sulphur atoms to the number of ethylenically unsaturated or saturated groups of 3 carbon atoms should be in the range 2: 1 to 12: 1.  The hydrocarbon reactant and sulphur are preferably mixed prior to, or simultaneously with, introduction into the reactor and preheated in the vapour phase.  An inert carrier gas can be used and the preferred pressures are 0.5-5 atmospheres at a contact time of 0.5-8 seconds.  The trithione is separated from the reaction mixture by conventional means such as crystallization, distillation, or extraction.  The process may be carried out in a batchwise or continuous manner.  Hydrocarbon reactants having two aliphatic groups capable of reacting with sulphur to form trithione groups include hydrocarbons having a benzene nucleus connecting two aliphatic chains of three carbon atoms e.g. diisopropylbenzene, dipropylbenzene, dipropenylbenzene and diisopropenylbenzene. Such reactants yield products containing two trithione nucleii.

Abstract: 1433061 Valves EATON CORP 22 March 1973 [24 March 1972] 13932/73 Heading F2V [Also in Divisions F3-F4 and G2-G3] A temperature responsive vacuum modulating valve assembly comprises a casing 24 defining a vacuum chamber 25 having a vacuum supply port 31 and an air inlet 35 controllable respectively by movable valves members 43, 41 which are linked by a stem 44, and a modulated vacuum output port 32, a flexible diaphragm 37 which forms one wall of the chamber 25 and sealingly engages a member 33 which defines the air inlet 35 and is movable inwardly and outwardly of the chamber 25, and two bimetallic temperature sensitive elements 15, 19 connected to and exerting a resultant force on the member 33. Both valve members 41, 43 are in their closed positions when the force exerted by the elements 15, 19 is balanced by the force created by the vacuum in chamber 25 acting on the diaphragm 37. When the member 33 is moved outwardly from the chamber 25, the valve member 41 remains closed and the valve member 43 is moved to an open position, whereupon the vacuum in chamber 25 is increased until the force on diaphragm 37 is sufficient to close the valve member 43. Upon the member 33 being moved inwardly of the chamber 25 from the position shown, the valve member 43 is held in its closed position and the valve member 41 moves relatively to its valve seat to vent the chamber 25 partially or completely to atmosphere. Supports for the bimetallic elements 15, 19 are mounted on the casing 24. The element 15 is pivotally mounted on a pin 45, engages a pin 48 which is fixed to the member 33 and is calibrated by a screw 27 which is rotatable through a Bowden wire and a disc 56 secured to the screw 27. A stop member 61 pivotally mounted on a pin 59 has a tooth 62 and a lug 64 engaging corresponding recesses in a slot in the disc 56 to hold the screw 27 in its initially adjusted position. The lug 64 has to be broken before adjustment of the screw 27 is possible. The element 19 is supported at 75 on knifeedges and engages a pin 79 which is held in openings 80 in legs 81 of a U-shaped member which is secured to the member 33. The legs 81 extend through slots (83, Fig. 2) in the element 19. A support 71 for the element 19 and the legs 81 are made of stainless steel of substantially the same thickness as the elements 15 and 19 to avoid undesirable heat transfer. The thickness may be 0À005 to 0À006 inch. The valve assembly is used in a vehicle air conditioning system having a blower which delivers fresh air through a duet 11 spaced from an outlet duct 16 to induce a flow of recirculation air from the vehicle interior through a duct 17, the elements 15, 19 being mounted respectively in ducts 11, 17. The vacuum output port 32 is connected to a vacuum motor which actuates a pivoted damper controlling the flow of air its heat exchange contact with an evaporator and thence to the vehicle interior.

In an arrangement for sorting sheets of material cut from a moving web of material and having the same width as the web, the web is scanned across its width by a plurality of photo-cells scanning adjacent sectors, and fault signals indicative of the position along the length of a web of a fault, effect the rejection of imperfect sheets, the cells each of which are provided with a pre-amplifier being grouped electrically, each cell and each group being connected to respective "OR" gates through which the reject mechanism is actuated. Reject signals are recorded on a loop of magnetic tape moving at the same speed of the material to introduce the delay corresponding to a faulty section arriving at the sorting point, the fault signals being erased subsequent to sheet rejection. The paper is inspected whilst passing over a darkened roller by the cells, which are housed in a sequence of adjacent compartments in the inspecting head. The paper surface is illuminated by a strip light and an optical fault observer is provided for use in adjusting the sensitivity.
