Title: Improvements in and relating to the manufacture of composite or multiply web or sheet material or articles
IPC: B32B27/00
Filed: 1943-06-25
Abstract: Compound sheet material is made by subjecting to heat and pressure between pairs of rolls 27, 28, 29, webs of pervious material which have been impregnated with an aqueous dispersion of a thermoplastic or thermosetting <PICT:0569115/IV/1> plastic material while being led from supply rolls 19 around pervious suction drums e dipping into troughs 10 containing the impregnant.  The webs may be pre-wetted by passing under rollers 21 dipping in tanks 20.  The webs are removed from the drums at a portion of the circumference which is not subjected to suction by doctor knives 23 and supported by rolls 26 are fed to the rolls 27-29 heated by steam; and additional heat may be provided, e.g. by a radio - frequency field before and between the pairs of rolls.  Where a thermosetting material is used, the compound sheet material may be part-cured while passing between rolls 27-29 and subsequently moulded and, e.g. to form channels or pipes completely cured as a web or sections cut therefrom by a guillotine 30.  The pervious webs may be woven fabric or felt of animal, vegetable or mineral fibres, such as wool, cotton ramie, asbestos, or glass, singly or in combination, wood veneer, or webs produced by compressions, felting, or extrusion from powdered or disintegrated waste fibrous material, e.g. cotton, wool, linen, or jute waste, sawdust, which may be treated with calcium hydrosulphide.  The layers may be perforated or roughened.  Sheets or webs of plain corrugated, embossed or perforated metal or wire gauze may be incorporated without treatment on the suction drums, as inside or outside layers. Suitable dispersions are made by dissolving sulphonated ocenol or sodium stearate in a cresol-formaldehyde condensation product, and mixing the solution with a 3 per cent aqueous glue solution, or by polymerizing an emulsion of methyl methacrylate and benzoyl peroxide in an aqueous solution of sulphonated ocenol. Urea-formaldehyde resin or a polyvinyl compound such as polystyrene may be used.  The thermosetting or thermoplastic material may be dissolved in an alcohol and emulsified in an aqueous solution containing casein, triethanolamine, ammonia and lauryl sulphonate.  A layer of varnish may be sprayed on an outer or inner web on its way to the pressure rolls.  The outer plies may be of glass fibres and the core of cheap filler material. Specification 551,179, [Group VIII], is referred to.

Title: Improvements in distilling liquids by the introduction of another liquid into the heated liquid to be distilled
IPC: B01D1/14
Filed: 1928-04-10
Abstract: 313,254. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). April 10, 1928. Purifying fatty, mineral, and tar oils; fatty acids, obtaining.-In distilling by the introduction of liquids such as benzine or water beneath the surface of liquids from which volatile substances are to be expelled e.g. fats or mineral oil, coal tar oil, brown coal tar oil &c., the temperature being such that the first liquid is explosively vaporized in the second and carries the volatile constituents away with the vapour, an apparatus such as that shown is used for introducing the first liquid without premature volatilization. In this apparatus water &c. heated and under pressure is circulated from tube A to tube B and is admitted in small quantities at a valve F into the liquid to be distilled. In an example, pea-nut oil, containing 5 per cent of free fatty acid is heated to 250' C. in a vacuum apparatus and water at 175‹ C. and 8 atmospheres pressure is passed into it and explosively vaporized.
Patent GB-236689-A (GB)
Title: Improvements in or relating to guards for machinery
IPC: F16P3/04
Filed: 1924-04-30
Abstract: 236,689. Siemens Bros. & Co., Ltd., and Riber, C. R. April 30, 1924. Interconnecting guard with starting-gear; guards, controlling; gearing for starting machinery requiring both hands of operator to be occupied.-In power presses, guillotines, bending - machines, &c., a guard is operated by pneumatic, hydraulic, electric, or other power means distinct from the energy of the moving parts of the machine, the starting-handle of the press &c. being normally checked or locked by means removed when the guard is actuated. The guard-actuating means may be controlled by a handle, so that both the operator's 'hands must be employed to start the machine. Depression of the spring-returned starting-handle 43, carrying a serrated locking-plate 44, is normally prevented by a detent 42 mounted on a shaft 39. When a handle 46 is gripped and depressed against the action of a spring 51 to operate the guard, the tail 49 of a latch 47 abuts against a flat 50 on a slotted arm 45, whereby the handle 46, in its guard-operating movement, also rotates the shaft 39 against a spring 54 to withdraw the detent 42, the motion of the shaft being limited by members 56, 57. A stop 55 prevents the handle 46 from being depressed far enough to turn the shaft 39 without previous actuation of the latch 47. If the latch is released before full movement of the handle 43, the detent engages the serrated plate 44 under the action of the spring 54. The lazy-tongs guard 5 is expanded by a. piston 2 in a slotted pneumatic cylinder 1, the ends of which are alternatively connected to a pressure supply 18 or exhaust aperture 19 by pipes 13, 14 and a slide valve 16. The movement of the handle 46 is conveyed by a link 38 and cam 36. and roller on a slotted link 33 to a slotted lever 32 pivoted on a fixed bracket 15. The lever 32 lies in the groove 31 of a member 29, in which slides the integral shank 26 of a thimble 25 and to which is screwed a larger thimble 23 slidable in a part 22 of the bracket 15. An adjustable stud 27 carried by a bracket 28 on the press plunger supports the parts 25, 26 against the pressure of a strong spring 52, which also causes the thimble 23 to hold up the valve 16 against a light spring 21. Depression of the lever 32 lowers the parts 29, 23 and allows the valve to admit air to the pipe 14 and to pass air from the pipe 13 to atmosphere, so expanding the guard 5. When the press plunger descends, the thimble 25 falls under the spring 52 and, as the rod 33 can rise under its spring 35 without raising the lever 32, the guard can only be collapsed when the plunger again reaches its topmost position. Accidental fall of the plunger also expands the guard. The Provisional Specification describes a lazy-tongs guard having plates so attached to the elements as to form a continuous screen when expanded, and states that an interlock between the guard-actuating device and press driving-gear may be provided.

Title: Improvements in and relating to bell gas holders
IPC: F17B1/013
Filed: 1931-04-11
Abstract: 361,798. Gas holders. MASCHINENFABRIK AUGSBURG-NURNBEBG AKT.- GES., Nuremberg, Germany. April 11, 1931, No. 10743. Convention date, April 16, 1930. [Class 54.] A waterless gas holder comprises a bell c movable vertically relatively to a fixed base a which is provided at its edge d with liquid, gaseous or semisolid grease sealing means. The base a may be supported by frame b and guided by a central tube f which allows the escape of gases leaking past the seal. Guide rollers m are provided between the bell and frame and bell and tube. If no guide tube is provided additional rollers are provided on a downward extension of the bell. The tube f may be extended to the ground or to the outer part of the frame b. Blocks x may be provided on the frame b to support the part of the bell not reinforced by the internal gas pressure against wind pressure. Tar oil distributing devices q prevent the adherence of ice to the shell and heating devices may be provided around the base a. The pressure of the gas in the bell is regulated by concrete weights l or by water ballast provided on the bell top which may be flat or dished and formed with an upstanding rim and partitions to ensure an even distribution. The bell may be constructed as a helically guided or a telescopic holder and may be at such a height that when lowered its lower edge sinks into an annular gutter in the ground. The upward movement of the bell may be limited by stops on the tube f or frame b so as to allow a narrow gap between the bell and base through which excess gas can escape, or safety valves may be provided on the bell. In constructing the holder, the frame b and base a are first erected and the cover of the bell is then put together on the base a. The shell of the cover is then built on to the cover from the top downwards from a staging temporarily attached to the frame b, the cover being raised as the work proceeds either by gas pressure or mechanically, the tube f being used as an erecting mast. The horizontal seams of the plates forming the bell are preferably welded and the vertical seams are covered by plates secured by rivets. The rivets are preferably countersunk on the inside so as to allow the plates to be utilized as guides to prevent the bell from turning.

Title: Improvements relating to driving mechanism for mechanically propelled vehicles
IPC: F16H61/02
Filed: 1919-05-01
Abstract: 146,668. Mason, W. May 1, 1919. Variable-speed epicyclic gearing comprises friction clutch members j connected to epicyclic train parts, which members are engaged after the engine clutch has been disengaged, so that the gearing turns solid with the driven shaft b, thus facilitating the engagement of a dog clutch u sliding on the shaft b. In one arrangement, a sun gear c secured to a driving-shaft a meshes with planet gears k, which mesh with an internally toothed ring i. Gears l secured to the gears k are connected through idlers (not shown), to a sun gear d loose and connected to a brake drum c. An internally toothed ring h is meshed by gears o secured to the spindles of the idlers or of the gears k. A carrier f of the planet gears carries a brake drum g. The rings h, i carry the friction members j and are connected to claw clutch member r, q in line with a like member s secured to the shaft a. The sliding member u is engaged with the member s for solid driving, with the member r for intermediate and low speeds, and with the members q for reversed driving, the appropriate member e or g being held against rotation. The clutch u and brakes are controlled by a lever 2, Fig. 6. Movement to left and right of Fig. 6 operates the clutch u through links 5, 6. Movement up or down of Fig. 6, by carrying with it a pivoted frame 3, operates one brake or the other through links 7, 7<1>. The frame 3 is connected by a link 12 to a toggle 10 which is straight in the neutral position when the brakes are off. A small extra movement of the engine clutch disengaging lever moves a part 14, which through a spring 16 and the alined toggle 10 moves a lever 11 to engage the friction members j, Fig. 1. In a modification, the element u is replaced by two sliding clutch members feathered one inside the other. In this case, the additional clutch operation is effected by a longitudinal movement of the lever 2.

Patent GB-741438-A (GB)
Title: Improvements in or relating to electric pulse reshaping circuits
IPC: H03K5/135
Filed: 1953-04-21
Abstract: 741,438. Pulse shaping circuits. SOC. D'ELECTRONIQUE ET D'AUTOMATISME. April 21, 1953 [April 30, 1952], No. 10954/53. Class 40 (6). In a pulse reshaping circuit of the type in which a distorted input pulse to be reshaped and a synchronizing pulse input are applied to a valve having a transformer in its anode circuit from the secondary of which the reshaped output pulses and a feed-back voltage are derived, the output pulses are limited in amplitude by a rectifier connected between the output lead and a constant bias voltage. Fig. 1 shows a pulse reshaping circuit in which valve 1 is rendered conducting at its cathode by negative synchronizing pulses applied periodically to its cathode via a transformer having a secondary 3. The positive-going distorted pulses which are to be reshaped are applied at input 12 to a network to the second input 13 of which a positive feedback voltage is applied from feed-back channel 24. The voltage at the junction 14 of rectifiers 16, 17 follows the variations in the higher of the two voltages applied at 12 and 13 so that when a synchronizing pulse is applied at 3 simultaneously with an input pulse at 12, valve 1 conducts to produce an output pulse at 10 which is terminated only when the synchronizing pulse at transformer 3 ceases. The negative going pulse at the anode of valve 1 is limited by rectifier 19 and the network 8, 9, 11 in the output circuit prevents any negative pulse appearing at the output 10. In a modification, Fig. 3 (not shown) the rectifier which limits the anode voltage swing of the triode comprises two crystal rectifiers associated with the feedback channel and a constant bias source. In a further modification shown in Fig. 4 the synchronizing signal is applied via a rectifier network 22, 28 to the control grid of valve 1 so that the valve conducts only in the presence of a synchronizing signal and an input at 12 and/or 13 applied simultaneously.
