Title: Improvements in scouring implements
IPC: A47L13/17
Filed: 1935-09-17
Abstract: 462,907. Scouring-appliances. METAL TEXTILE CORPORATION. Sept. 17, 1935, No. 25790. Convention date, May 7. [Class 28 (ii)] A scouring-pad comprises a core or main body of foraminous, resilient material, e.g. sponge rubber, and a metallic mesh envelope, the marginal edges of which are imbedded in and bound with the body. As shown, the marginal edges of the envelope 11 are secured by attaching to the sponge rubber body a layer 13 of vulcanized rubber, filled or impregnated with a pulverulent abrasive material, e.g. powdered emery or carborundum, so that rough scouring is effected by the envelope 11 and polishing by the layer 13 which may be vulcanized directly on to the main body. In a modification, the applied layer 13 is dispensed with, the envelope being applied before vulcanization of the body and its marginal portions inturned and imbedded in the body. The pores of the body, or that portion of the body which is not covered by the envelope, are filled with grit, emery or carborundum which is held by the vulcanization or by the use of a suitable cement or adhesive. The envelope is preferably produced by knitting flat, ribbon-like wire of non-corroding metal, e.g. zinc, copper, or aluminium.

Title: The manufacture of oxidation products
IPC: C07C51/58
Filed: 1939-09-14
Abstract: 534,732. Trichloracetyl compounds. KIRKBRIDE, F. W., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Sept. 14, 1939, No. 25792. [Class 2 (iii)] Trichloracetyl chloride is produced by oxidizing perchlorethylene with oxygen in the presence of heat and actinic radiation, any isomer such as perchlorethylene oxide being decomposed by continued heating or by adding an anhydrous chloride such as aluminium chloride or a secondary or tertiary anine. The oxidation may be assisted by adding a small proportion of chlorine, though this produces some hexachlorethane. If the reaction is effected at 50 ‹C. the quantity of perchlorethylene oxide produced may be considerable, especially if the oxidation is not carried as far as possible, but at 100-110‹C. with full oxidation the quantity is small. The crude product may be converted to other trichloracetyl compounds ; for instance an ester may be produced by refluxing with an alcohol or the amide by treatment with ammonia preferably in the presence of a solvent such as trichlorethylene in which the amide is insoluble ; trichloracetic acid or an ester thereof may be made by heating with water or an alcohol the oxidation product without first treating with aluminium chloride or an amine, the heating serving to convert the perchlorethylene oxide to trichloracetyl chloride and also to hydrolyse this substance. In examples (1) trichloracetyl chloride is prepared as described above, using triethylamine as the amine reagent ; (2) with 17 per cent. of chlorine in the oxygen and working at 100‹C. some hexachlorethane is produced together with the trichloracetyl chloride ; (3) the crude trichloracetyl chloride is reacted with ammonia with trichlorethylene as solvent, yielding trichloracetamide ; (4) the crude trichloracetyl chloride is esterified with 2-ethyl-n-hexyl alcohol. Specification 523,555 is referred to.

Title: Improvements in and relating to vehicle suspension systems
IPC: B60G17/033
Filed: 1966-06-10
Abstract: 1,103,999. Controlling vehicle suspension height. ALFRED TEVESMASCHINEN-UND ARMATURENFABRIK KOMM. GES. 10 June, 1966 [23 Oct., 1965], No. 26003/66. Heading B7D. In a vehicle suspension system comprising a variable-height suspension strut 6, 7, 8, 9 for each wheel and a single control line for supply and return of pressure fluid extending between each strut and a central height control unit 1, each strut 6, 7, 8, 9 includes valve means which permit entry of pressure fluid to the strut from its control line when the strut is below a set, raised position and permit discharge to the line when the strut is above a set, lowered position. When a parking brake is applied or a door opened as the vehicle comes to rest a signal is transmitted by mechanical, hydraulic electric or pneumatic means to the control unit 1 which connects the control lines to a return line 4 so that the vehicle body is lowered to the set, lowered position to facilitate passenger entry. As the door is closed a second signal is transmitted to the control unit 1 which connects the control lines to an accumulator 2 charged from a pump (not shown) through a supply line 3 and a non-return valve 10, whereupon the body is returned to the set, raised position. Automatic means act on the control unit 1 when the body reaches the set, raised position to cut-off communication between the control lines and the return line 4 or accumulator 2 when the vehicle is running.

Abstract: 704,055. Making slip-lasted shoes. HERLIHY, W. F., and HERLIHY, J. J., [trading as LOWELL COUNTER CO.]. Oct. 20, 1952, No. 26246/52. Classes 17(1) and 17(2) The method of making slip - lasted shoes with moulded counters of the kind described in Specification 659,705 is modified, to facilitate turning down the wrapper, by forming a definite fold line in it adjacent to the seam by which the quarter stiffener 4, sock lining 6, upper 1 and wrapper 5 are secured together. If desired, the counter may be subjected to a preliminary moulding before it is assembled and united with the other shoe parts. The fold line may be formed by compressing the surface of the quarter by an edge portion 10 of the outer mould member 9 which deflects the wrapper outwards from the quarter. This pressure may be maintained while the wrapper is turned. The inner and outer pieces of the quarter may be coated with thermoplastic adhesive which under pressure between the heated dies bonds the plies together.

Patent GB-289106-A (GB)
Title: Improved means for operating multi-way control cocks for liquid measuring and delivering apparatus
IPC: B67D7/16
Filed: 1926-10-22
Abstract: 289,106. Smith, H. W., Smith, R. V., and Smith, I. C. V. Oct. 22, 1926. Fixed-chamber apparatus.-The devices for filling the measuring-chamber are interlocked until the measuring-chamber is fully charged, and the measuring-chamber is cut off from the supply tank until it is fully discharged, the mechanism shown being particularly adapted for use in apparatus such as that described in Specification 234,857, and in combination with that described in Specification 289,107. Fig. 1 shows a petrol &c. measuring-apparatus with a threeway cock 1, the spindle 1<a> of which has two, twoarmed levers 6, 7, fixed thereto, and a shorter arm 10, loose on it. Between the shorter ends of the levers 6, 7 is interposed a pin 8 pivotally connecting the arm 10 to a lead 9, which is connected by links 11, 12 to a pin 13 extending through a closed slot 14, Fig. 3, in a guide 15. On the wheel 4 of the pump is a plate 16 movable on a pivot 17, and carrying a pair of rollers 18, 19 engaging with the pin 13. When the pump wheel 4 is rotated clockwise, as shown in Fig. 3, the stud 18 engages the pin 13, and pulls the arm 6 downwards, setting the cock 1 so as to charge the measuring-chamber. When this has been charged, the pawl 20, Fig. 2, is released as described in Specification 289,107, the pin 13 is carried further round the guide 14 by the pull of the spring 6<a>, and the cock is again set in neutral position. To discharge the measuring chamber, the pump wheel is rotated counter-clockwise, and the pin 13 is carried to a point near the top of the guide slot 14; the spring 7<a> is then stressed and the cock 1 set to discharge the chamber. Continued rotation of the pump will discharge the chamber, and the trip gear will release the cock so that the spring 7<a> again places the cock in the neutral position. The pawl 20 rotates with a spindle to which is fixed an arm 20b with a pin 20<c> which engages a lever 23 and operates an air-release cock 21. Normally this is open; the lever 23 closes it when the measuring-chamber is under suction for charging; it is opened by the spring 24 when the chamber is to be discharged. Should it be desired to discharge the measuring-chamber by pressure, the air inlet of the cock 21 can be fitted with a non-return valve which would close under the pressure of the pump.

Title: Improved method and means for securing screws, spikes and the like in solid materialsuch as brickwork, plaster and stone
IPC: F16B13/14
Filed: 1935-09-25
Abstract: A plugging-composition for the attachment or embedding of screws, spikes, nails, &c. in solid material such as metal, plaster, brickwork, stone or wood comprises a filler of flexible fibres of such a length, e.g. 1/8 to 1/2 of an inch, as to be capable of interlacing with each other but insufficient to wind round the screw or other member, and a non-drying binder sufficiently adhesive to form a coherent mass with the filler but not sufficiently adhesive to prevent disintegration of the fibres, when distortive forces are applied to the mass.  Mill puff is specially suitable as a fibre, but short cotton or silk fibre, shoddy, or thin wire may be used. Powdered filler such as slate dust, powdered glass or pumice powder, and a powdered adhesive such as dextrine may be added.  The fibrous adherent material formed when the cellulose constituents of chopped straw are partly broken down by chemical means forms a satisfactory plugging material but is improved by the addition of oil and slate powder. Suitable binders are petroleum jelly or heavy oil, grease, wax, or a non drying aqueous adhesive such as a mixture of water, glycerine and lecithin, or water, gum copaiba, sugar and lanolin. A corrosion-inhibiting substance such as zinc or cobalt chromate may be added.  In an example, a plugging composition comprises 26 parts by weight of millpuff, 21 parts of petroleum jelly, 29 parts of dextrine, 20 parts of fine slate powder and 5 parts of zinc chromate.

Title: Ground appliance for controlled deceleration of aircraft on landing
IPC: B64F1/02
Filed: 1959-08-04
Abstract: 886,125. Aircraft arresting gear. FIAT S.p.A. Aug. 4, 1959, [Aug. 8, 1958 ; Jan 28, 1959], No. 26589/59. Class 4. [Also in Group XXXII] Aircraft arresting means comprises two similar chains of telescopic shock-absorbers, the two movable members of each shock absorber (except those at the ends of the chains) being each connected with a movable member of an adjacent shock absorber, each chain being attached at one end to a fixed point on one side of a landing area, and at the other end to a common member adapted to be coupled to a landing aircraft, the shock absorbers including throttling ports or the equivalent of progressively decreasing areas in each chain. The Figure shows part of two consecutive shock absorbers in a chain. Each comprises a cylinder 4 with end caps 5 and 6, and a piston 9 and piston rod 8. The piston rod 8 terminates in a ball 10 forming a universal joint with spherical seatings on a flange 6a on the adjacent cap 6, and a member 11 screw threaded on to flange 6a. Each shock absorber is surrounded by a rubber sleeve 15 having at one end a ring 16 formed with internal projections 16a, and at the other end with a channel section ring 17 having outward projections 17a, such that adjacent sleeves can be secured together by interlocking of the projections 16a and 17a in bayonet-joint fashion. Each ring 17 also abuts a flange 7 on the adjacent cap 6. When the shock absorbers are extended by a landing aircraft, the sleeves stretch, and, while contributing little to the arresting effect, suffice to contract the shock absorbers when unloaded. Fluid throttling ports 14 are provided in each piston 9, and the ports of successive pistons are graduated in size, so that some shock absorbers become completely extended before others. By this means, the deceleration of the aircraft may be held constant at, say 3g, or rise to a maximum and thereafter remain constant. In a modification, the expansion and contraction of the annular space between each shock absorber and its sleeve is arranged to have a pumping effect and causes airflow round the cylinders 4 for cooling purposes. The chains of shock absorbers may be connected to a length of steel cable engageable by a tail hook or the undercarriage of an aircraft, and may normally lie in ditches laterally of the runway.

Abstract: Polyvinyl acetals are manufactured by acting on an aqueous emulsion of a polyvinyl ester containing a polyvinyl alcohol or a water-soluble derivative thereof as emulsifying agent, in the presence of a mineral acid or a strong organic acid, with a quantity of a carbonyl compound sufficient to convert at least part of the polyvinyl ester to a polyvinyl acetal.  Specified materials are: water-soluble derivatives of polyvinyl alcohol-polyvinyl alcohols partly esterified with an organic acid, e.g. acetic, propionic, or butyric acid, or partly acetalized with an aldehyde, e.g. formaldehyde, acetaldehyde, butyraldehyde, octyraldehyde, or. benzaldehyde; polyvinyl esters-the formate, acetate, propionate, and butyrate; acid catalysts-mineral acids, e.g. sulphuric, hydrochloric, nitric, phosphoric, hydrofluoboric acids, and strong sulphonic acids, e.g. toluene sulphonic acids; carbonyl compounds-formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, octyraldehyde, benzaldehyde, cyclohexanone and methylcyclohexanone.  There may also be present an alcohol, e.g. methyl, ethyl or propyl alcohol. In examples (1), (2), (4), an emulsion of polyvinyl acetate in aqueous polyvinyl alcohol is acetalized by acetaldehyde in the presence of methyl alcohol and sulphuric acid, by butyraldehyde in the presence of ethyl alcohol and p-toluene sulphonic acid, or by octyraldehyde in the presence of ethyl alcohol and phosphoric acid; (3) an emulsion of polyvinyl butyrate in aqueous-alcoholic polyvinyl alcohol is acetalized by acetaldehyde in the presence of methyl alcohol and hydrochloric acid.  The product of example 2 may be worked up as threads.  Specifications 466,173 and 469,319 are referred to.
Patent GB-158338-A (GB)
Title: Improved means associated with cranes for the operation of tip-buckets
IPC: B65D88/56
Filed: 1919-10-31
Abstract: 158,338. Macnamara, C. M., and Reid, W. Oct. 31, 1919. Tip-buckets.-A tip-bucket is dumped by the engagement of a false bail with a pivoted hooked member mounted on the end of the crane jib. The latches 1, which engage depressions in the rim of the bucket, are pivoted to the bail B and connected to the false bail 3 so that they are released to allow the bucket to tip by gravity when the false bail is raised. The pivoted member 7, which is U-shaped in cross-section, normally hangs clear of the hoisting-rope, as shown, under the action of a counterweight 9. Various means, as hereinafter described, may be used to swing the member 7 towards the rope when the bucket is approaching the desired elevation, so that the member 4 is guided between the arms of the member 7. As the hoisting continues, the bail B is moved outwards in passing the cam-shaped surfaces of the hooks 8 which also guide the bail into a predetermined plane for tipping. On passing above the hooks the bail moves into line with the hoisting rope again and thus brings the false bail directly over the hooks. On lowering, the false bail is engaged and raised by the hooks to dump the bucket. On raising the bucket again and allowing the member 7 to swing back to the illustrated position, the hooks are disengaged and the bucket can be lowered for a second operation. The member 7 may be actuated entirely by gravity by manipulating the jib, or the movement of the latter may be used to apply a tension to a cord 10 suitably anchored on the crane structure. The cord can be actuated also by hand or by being connected to the winding drum or to a fixed point on the hoisting rope. When it is desired to vary the plane of the member 7 relatively to the plane of the jib, the member 7 is pivoted on a bracket which in turn is suspended from the jib. Thebuckets used are preferably of the self-righting type, and may be arranged to tip on one side only.
