Abstract: 690,511. Skimmer bucket excavators. PRIESTMAN BROS., Ltd. Oct. 29, 1951 (Nov. 28, 1950], No. 29122/50. Class 68(i) In a skimmer excavator in which the bucket 7 is drawn along the flanges 4 of a boom 3 by a hoist rope or ropes 13, an additional rope or ropes 23 are attached to the rear of the bucket and are paid out at exactly the same rate as the hoist rope or ropes 13 are wound in, and vice-versa. The hoist rope or ropes are wound on a winch 16 which can be driven in either direction and which is co-axial with the pivotal attachment 15 of the boom 3 to the cab of the excavator 1, and the additional rope or ropes 23 are also wound on said winch but in the opposite direction. Thus the bucket can be positively hauled back along the boom or when the bucket is allowed to return along the boom due to gravity and would strike a stop 26 at the inner end of said boom before it can be checked by braking-the winch drum 16, the unnecessary uncoiling of the hoist rope or ropes 13 from said drum is avoided.

Patent GB-364626-A (GB)
Title: Combined hydraulic lifting jack and shock absorber for motor vehicles
IPC: B60S9/12
Filed: 1930-09-30
Abstract: 364,626. Shock-absorbers. GAUTHIER, R., 25, Avenue de la Laiterie, Cointe, Liege, Belgium. Sept. 30, 1930, No. 29267. Convention date, Sept. 30, 1929. [Class 108 (iii).] In a combined hydraulic shock-absorber and lifting - jack for motor vehicles, the shock absorber piston is automatically locked when the jack is in operation so that the axle is positively lifted with the frame without sagging of the suspension springs, the normal function of the shock absorber being restored when the jack returns to the inoperative position. The shock absorber piston 23 is connected through arms 28, 29 on a rock shaft and a link 31 to the wheel axle 32 and normally functions by causing liquid to pass through a throttled passage 25 from one side to the other of the piston. The passage 25 leads from the lower end 22 of the piston chamber to a valve chamber 15 with an outlet 27 leading to the upper end 26 of the piston chamber. The valve chamber 15 is mounted on the top of the jack which comprises telescopic plungers 12, 13 in a cylinder 10 having a fluid supply inlet 14 at the upper end, the plungers being forced down by fluid pressure and returned by springs 36, 37. Within the valve chamber 15, a spring pressed piston 16 is normally held up by a stem 27 passing through apertures 19, 21 in the upper ends of the jack cylinder 10 and plunger 12 so as to bear upon the end of the plunger 13. Thus, when the plungers descend in the operation of the jack, the stem 17 is unsupported and the valve piston 16 is forced down by the spring 20 into a position cutting off the flow between the upper and lower sides of the shock absorber piston, this position being determined by a valve member 18 on the stem which seats on and closes the aperture 19 for the passage of the stem. The stem is raised, restoring the action of the shock absorber, when the jack plungers return to the inoperative position. The jack may be attached to the vehicle frame at such an angle that, when the axle tilts owing to the flattening of a tyre, the jack will then be vertical. It may be connected to the frame by means of a slightly deformable rubber or like plate, or the jack and shock absorber may be constructed as a monobloc apparatus and secured to the chassis frame by a common rigid plate. Specification 331,826, [Class 108 (iii), Springs &c.], is referred to.

Title: Improvements relating to motors of electric locomotives and the like
IPC: B61C9/38
Filed: 1926-11-22
Abstract: 277,198. Jacobs, R. E. Nov. 22, 1926. Polo - pieces; mounting rotors; casings. - A pair of side plates or brackets 4 supported at their ends en wheel axles are connected by two hollow cylinders 6 which act as housings for the motors A, B and carry the pole-pieces. The motor shafts 38, 39 are supported by split bearings in two pairs of sliding panels 11. At the bottom of each of the cylinders 6 is a longitudinal gap 19. When it is desired to remove an armature the stem of a lifting jack mounted on a wheeled truck is placed in the gap 19. The weight of the armature having been taken by the jack, the panels 11 are slid aside and the armature moved endwise out of the housing. Normally the gaps are closed by removable plates 18, Fig. 4, on which pole-pieces 23 are mounted. Connection with adjacent windings is effected by a screw 29 in an insulating bushing 21 and contacts 24, 27.
Patent GB-346407-A (GB)
Title: Distillation of petroleum oils
IPC: C10G7/00
Filed: 1929-09-30
Abstract: <PICT:0346407/III/1> Hydrocarbons, distilling.--Oils are distilled by heating them in a pipe coil, flashing the products under atmospheric pressure in a vapour separating chamber, withdrawing the residual oil and subjecting it while still hot to a high vacuum to effect further distillation.  Crude oil from a tank 1 is passed by a pump 2 through condensers and heat exchangers 3 .. 7 to a vapour box 8 where light vapours are separated.  It is then pumped by a pump 9 through a heated pipe coil 10 and discharged into a vapour box 11 maintained at atmospheric pressure, the vapours evolved being condensed in the fractional condenser 7.  The residual oil is passed through a line 13, having a regulating valve 12, to a vacuum box 4 maintained under a vacuum of about 27-29,9 inches of mercury, and the vapours evolved are passed into the fractional condenser 6.  The box 14 may be heated.  The residues may be further refined to obtain lubricating oil, or may be distilled under high vacuum in a still 15 heated by molten metal to form coke, the vapours evolved being condensed in a condenser 17. Residues of an asphaltic nature may be passed through a barometric column 21 to vacuum stills 20, where they are treated with hot air to form asphalt.  The various parts of the apparatus may be insulated to prevent solidification of the residues. Specification 318,897, [Class 32, Distilling &c.], is referred to.  Reference has been directed by the Comptroller to Specifications p  264,476 and 305,846, [both in Class 32, Distilling &c.].
Patent GB-755721-A (GB)
Title: Radio wave pulse system and method
IPC: H03K3/78
Filed: 1951-12-17
Abstract: 755,721. Pulse shaping networks. CAUER, K. H. M. Dec. 17, 1951 [Dec. 18, 1950], No. 29558/51. Drawings to Specification. Class 40 (8). [Also in Group XL (c)] In a pulse communication, remote control, radio navigation or other system a pulse of radio frequency energy is transmitted which is, during the pulse, also frequency or phase modulated and at a receiver an amplitude peaking network of reactances is employed to reduce the pulse width and increase the pulse amplitude relatively to any accompanying noise without altering the pulse general waveform, before the pulse is then detected. It may then be displayed on a cathode-ray tube. The pulse may -αt<SP>2</SP> be of the form u=e .cos(2#fo.t+#t<SP>2</SP>+#) produced by amplitude modulating, say, a reflex klystron with a Gaussian error function waveform and linearly frequency modulating it simultaneously by a sawtooth voltage applied to its reflector electrode. In that case the receiver network may be n series connected lattice networks with series arms of inductance L = R/2#3## o  and diagonal arms of capacity C = 1/2#3## o .R where R is the terminating load resistance of the network and fo the initial frequency. More generally, the series and diagonal arms of a lattice network may have the values Z 1  = R j U m (#) / G m (#) Z 2  = R G m (#) / j U m (#) where G m  and U m  are the real and imaginary parts of the function (# o #3-j#)<SP>n</SP> / (# o #3+j#)<SP>n</SP> Alternatively the receiver lattice network may have resistances as the diagonal arms; or equivalent bridged-T networks may replace the lattice networks. Some of the impedance elements may be piezo-electric crystals, tuned circuits or cavity resonators, or short lengths of transmission line or waveguide. To avoid dielectric or other insulation breakdown, a relatively low amplitude pulse may be employed at the transmitter followed, after the aerial feeder line, by an amplitude peaking network as above. There may be employed also, in the feeder line, an inverse network for decreasing the pulse amplitude and increasing its width.

Filed: 1972-06-23
Abstract: 1415012 Blowing glass EMHART (UK) Ltd 7 June 1973 [23 June 1972] 29561/72 Heading C1M [Also in Division F2] A valve block for an IS glassware forming machine has a plurality of valve combinations arranged in two rows each combination comprising a solenoid-operated pilot valve 4 and a three-way main valve 3, a pilot line 36 being common to all the pilot valves and an exhaust or supply chamber 43 being common to all the main valves. As shown the pilot valve member 31 is biased by a spring 37 against the rubber seat 34 and is moved on energization of the solenoid coil 28 to close the vent passage 29 and communicate the pilot line 36 with an outlet passage 40. Pressure in passage 40 acts on the piston 24 formed at the end of the main valve member 12 to cause the supply passage 9 to be communicated with the outlet 10 and the outlet 10 to be cut-off from the exhaust passage 11 which communicates with the exhaust chamber 43. The block is formed of two castings 1, 2 which together define the chamber 43 and which may have supply chambers (55), (56) secured to opposite faces and feeding respective rows of main valves. The solenoid-operated pilot valves are operated by an electronic timing control unit and each have a manual override formed by a rotatable cylindrical barrel 47 having a semicylindrical extension 50 which moves the pilot valve member. The manual override may be replaced by a pneumatic override which is a three-way tap that normally connects bore 29 to atmosphere but which can be operated to connect it to pilot air pressure so as to operate the main valve 3.

Title: Improvements relating to fibres and other shaped articles of polyacrylonitrile
IPC: C08F220/44
Filed: 1955-10-18
Abstract: Fibres and other shaped articles containing acrylonitrile polymer are produced by extruding a solution of a cross-linked acrolonitrile polymer into a liquid hydrocarbon coagulant which is completely miscible with the polymer solvent at the spinning temperature.  The acrylonitrile polymer usually contains up to 15 mols. per cent (based on monomeric acrylonitrile) and preferably 2-8 mols. per cent of copolymerized mono-ethylenically unsaturated monomers, such as acrylic or methacrylic acids and their amides and esters, vinyl acetate and chloride, vinylidene chloride, and methacrylonitrile, and 0.001-0.3 mols. per cent of a polyethylenically unsaturated cross-linking compound. Suitably, the polymer contains 0.02-0.06 mol. per cent of such bi-ethylenically unsaturated compounds as divinyl benzene, methylene bisacrylamide, diallyl phthalate, ethylene glycol diacrylate or butadiene derivatives, or 0.005-0.02 mol. per cent of such tri-ethylenically unsaturated compounds as triacylo-hexahydrotriazine or diallyl malleate.  Alternatively if the polymer contains reactive acid groups certain polyvalent metallic compounds which react to form "salt bridges," e.g. magnesium or aluminium sulphate, may be used as cross-linking agents.  The polymer solvent is suitably dimethylformamide or dimethylacetamide, in which case the hydrocarbon coagulant should contain no more than 50% aromatics, or dimethyl sulphoxide or ethylene carbonate when the coagulant should contain 40-100% aromatics.  Kerosene, with or without aromatics, is a suitable coagulant, and spinning is preferably carried out at 80-150 DEG  C. with either co- or counter-current flow of coagulant.  The fibre obtained is stretched at 100-150 DEG  C. to 3-10 times original its length while it still contains 3-15% residual solvent and 2-15% coagulant.  This residuum should thereafter be removed by treating the product for some time at temperatures above 80 DEG  C. with hot aqueous ethanol, with a boiling solution of non-ionic detergent, or with steam, and the fibre obtained is then dried, above 100 DEG  C. if a translucent, vitreous, compact product is required, or below 100 DEG  C. if a porous, opaque, rugged product is preferred.  If, before drying, the fibre is boiled in 10% salt solution it does not turn opaque even at low drying temperatures.  If desired, the fibres before drying may also be treated with a cationic surface active agent.  The solvent and coagulant may readily be separated from the spent coagulant by cooling and separating the phases which form.  Water may be added to facilitate this separation but the solvent phase will then need to be redistilled to recover the solvent.  Specification 824,226 is referred to.
