Patent GB-278745-A (GB)
Title: Improvements in and relating to the manufacture of hydrocarbons and substances containing adsorbed hydrocarbons
IPC: C10G1/06
Filed: 1927-10-07
Abstract: 278,745. General Carbonalpha Co., (Assignees of Aarts, H. C. J.). Oct. 7, 1926, [Convention date]. Liquid fuel.-Methane and other hydrocarbons are produced by heating active carbon with hydrogen or gases containing hydrogen at 150-600‹ C. with or without a catalyst, at ordinary or slightly above ordinary pressure. The hydrocarbons produced may be adsorbed in the active carbon so as to form a solid fuel suitable for use in internalcombustion engines and for other purposes. The carbon may be obtained by heating carbon monoxide to 230-600‹ C. with or without a catalyst. Activated bone charcoal, wood charcoal and other activated materials containing free carbon derived from vegetable, animal, or mineral sources may be used. It mav be advisable to add a catalyst such as nickel, which may be effected by drenching the carbon with finely divided nickel oxalate or nitrate and reducing with hydrogen at a suitable temperature. When the process is effected at 150-400‹ C. the products are mainly saturated hydrocarbons, unsaturated hydro carbons being produced at 400-600‹ C. Coal, peat, wood, brown coal, and other carbonaceous materials may be gasified with or without a. previous distillation and with or without the use of steam, so as to produce a gas containing carbon monoxide, which is then heated to 230-600‹ C., preferably 300-500‹ C. The decomposition may be started by means of a catalyst such as iron, nickel, or cobalt oxide, but the carbon itself will act as catalyst when produced. Hydrogen is introduced into a closed vessel containing excess of the active carbon at 150-600‹ C., when hydrocarbons are formed and adsorbed by the carbon forming a more or less solid or plastic product; or the chamber may be provided with an outlet, the hydrocarbons being withdrawn continuously or otherwise. Heat is necessary to recover the hydrocarbons from the carbon, or the quantity of carbon may be only such as to combine with the hydrogen so that only gaseous hydrocarbons are obtained. When using a suitable final temperature high-boiling-point hydrocarbons are adsorbed and the lower hydrocarbons particularly methane are not adsorbed. When the solid adsorptionproduct is used as fuel in an internal-combustion engine, the heat of compression first separates the adsorbed hydrocarbon and then burns the carbon, the hydrocarbon being the last to react, avoiding knocking effects. The Specification as open to inspection under Sect. 91 (3) (a) includes the use of bone charcoal, wood charcoal, and " other animal, vegetable or mineral active carbonaceous materials " and states that when charcoal or a similar substance is used it is advisable to distribute therethrough a catalyst such as nickel, which is effected as above described. This subject-matter does not appear in the Specifications as accepted.
Patent GB-358222-A (GB)
Title: Improvements in or relating to railway car couplers
IPC: B61G3/16
Filed: 1930-09-05
Abstract: 358,222. Automatic couplings for railway vehicles. NATIONAL MALLEABLE & STEEL CASTINGS CO., 10600, Quincy Avenue, Cleveland, Ohio, U.S.A.-(Assignees of Bazeley, A. J. ; 9718, Logan Court, Cleveland, Ohio, U.S.A.) Sept. 5, 1930, No. 26621. Convention date, Sept. 9, 1929. [Class 103 (v).] In an automatic coupling for railway vehicles of the rigid jaw type, e.g. as described in Specification 252,567, [Class 103 (v), Railway &c. vehicles, Draught &c. appliances for], in which opposed shoulders 3 and hooks 4 on the two couplerheads 2 engage by a lateral movement and are locked by gravity locks 9 sliding in the cavity 10 between the jaws, rearward creeping of the locks when the couplers are in the operative position is prevented by co-operating means on the locks and on the lock-actuating levers 12. In the construction shown each lever 12 is pivoted on a transverse bolt 11 and comprises an external arm 13<1> to which an uncoupling chain or like member is connected and an internal portion 14 having a forward shoulder 18 which, by contacting with a stop surface 19 on the lock 9, prevents the latter from being forced too far inwardly when a coupling is being effected. When the lever 12 is rotated for uncoupling purposes, the shoulder 18 is moved out of the path of the stop 19, and an actuating cam 16 on the lever engages a projection 17 on the lock so as to retract the latter to a non-locking position. On the part 14 of the lever 12 and on the lock 9 respectively are cooperating bevelled anticreep surfaces 20, 21 so disposed that, when the coupler-heads are locked as in Fig. 2, any tendency of the lock to move rearwardly causes a lateral movement of the rear end 9<111> of the lock, jamming it tightly against the inner wall 23 of the cavity 10. Each lock is, however, cut away at 24 on its inner face so that, when a coupling is being effected, the forward end of the lock may have a limited lateral displacement sufficient to allow the bevelled surfaces 20, 21 to clear each other. Since the initial rotation of the uncoupling lever 12 also moves the bevel 20 out of the path of the bevel 21, the two heads can be uncoupled readily even when under draught strain, thus rendering the coupling suitable for use on a vehicle having pneumatic side buffers that tend to keep the coupler-heads under stress.

Title: Improvements relating to shaping microporous polyolefin sheets
Inventor: LUNDSAGER CHRISTIAN BENT
IPC: C08J9/36
Filed: 1965-06-23
Abstract: Microporous sheet material, suitable for shaping into articles and having a pore volume of at least 25%, is made of a solid composition comprising 6 2/3 -100% by volume of polyolefine having a standard load melt index of 0, 0-40% by volume of a substantially inert plasticizer and 0-93 1/3 % by volume of a filler. The sheet is made by first compounding a composition consisting of 5-65 volume per cent of the polyolefine, 5-60 volume per cent of filler and 90-30 volume per cent of plasticizer and then leaching out at least a portion of the filler or plasticizer or both by a suitable solvent or solvents. The polyolefine may be a mixture of a very high molecular weight polyolefine together with one of a lower molecular weight.  The filler may be water-insoluble or water-soluble, lists of materials falling into both categories being given in the Specification. In the examples, the microporous sheet is made by forming a compound of 15% by volume of polyethylene, 15% by volume of silica filler, 67% by volume of petroleum oil and 1% by volume of carbon black, and then shaping it into a sheet.  The sheet thus formed was then immersed in hexane at room temperature for one hour to extract the petroleum oil, thus forming a microporous sheet having a pore volume of about 65%.

Title: Improvements relating to shock absorbers
IPC: B60G13/08
Filed: 1939-01-17
Abstract: 560,048. Shock-absorbers. DOWTY, G. H. Jan. 17, 1939, Nos. 26719, 26720, 26721 and 26722. Divided out of 560,047. [Class 108 (iii)] Means for affording damped resilience comprise a pressure-tight chamber 5, a plunger 7 slidably extending into the chamber to afford resilience due to the elastic restoring forces of liquid filling the chamber and compressible by plunger movement under load, a head 12 fixed to the plunger and slidable within the chamber, and flow resistance means such as 16, included entirely within the headed plunger and movable therewith to afford energy dissipation by passage of liquid therethrough during plunger movement. In the construction shown in Figs. 1 and 2 applied to an aircraft undercarriage, the chamber or cylinder 5 is pivoted at 6 to a leg or strut 1, and the plunger 7 is pivoted at 11 to an arm 2 which carries the landing wheel 4 and is pivoted at 3 to the leg 1. When the plunger is forced into the chamber by increasing load on the wheel, the liquid in the chamber is compressed and exerts a resilient restoring force on the plunger ; at the same time the movement is damped by the flow of the liquid through apertures 15, 13 in the plunger head ,12, this flow being controlled by a shuttle valve 16 having a limited annular clearance in a recess 14 in the head. During the upward movement of the plunger and head, the liquid is forced past this annular clearance and the movement is damped accordingly. On the rebound stroke, when the head is moving downwardly, the valve 16 is carried upwards until it seats itself on a plug 15A with its stem 16A within an aperture 15 in the plug. More resistance to flow is provided on this rebound stroke, but a complete sealing of the passage is prevented by the provision of ducts 15B on the valve seating of the plug ; alternatively, or additionally, ducts may be provided on the upper face of the valve 16. The pressure, when the liquid is fully compressed, may be of the order of 40,000 to 50,000 lbs. per square inch. In a modification, Fig. 3 (not shown), the plunger is a differential one and has two slightly different diameters fitting in the two ends of the chamber 5, the head 12 being situated at the junction of the two diameters of the plunger. According to the first Provisional Specification, a relatively small volume of gas may be used with the liquid, the chamber may contain or be lined with rubber or the like, a series of shock-absorbers may be used, the piston of one forming the chamber of the next and the chamber may be reinforced by wire wrapping ; and according to the third Provisional Specification, the plunger operates against a compression spring and is hollow so as to form a second chamber in which liquid is compressed during the latter part of its stroke.
