Title: Sound recording and reproducing device
IPC: G11B27/00
Filed: 1951-10-25
Abstract: 697,146. Magnetic recording and reproducing apparatus. LOEWE OPTA AKT.-GES. Oct. 25, 1951 [Oct. 27, 1950], No. 24913/51. Class 40 (ii). In a sound recording and reproducing device, parts of the recording may be reproduced, without reversing the motion of the record, by arranging a reproducing head a distance after the recording head corresponding to about 10 to 120 seconds of playing time. As shown, a tape from drum 2 passes a recording head 4 and then passes over pulleys 6 so that a distance corresponding to the desired playing time is traversed before a reproducing head 5 is reached. In order that drum 2 need not be rotated when no recording is being done the pulleys 6 may be caused to approach together and thus free the desired length of record to pass head 5. If several parallel tracks recorded in succession are provided on a tape, the two heads may be side by side but arranged to engage different tracks.

Title: Improvements in lawn mowing and the like cutting machines
IPC: A01D34/02
Filed: 1920-08-30
Abstract: 173,562. Keyzer, J. N. M. Aug. 30, 1920. Lawn - mowers are constructed so that worn parts may be replaced easily and with improved means for mounting the cutters and for lubricating. The lower cutter-bar 25 is connected by screws 39, Fig. 10, to a tubular arm 22 projecting from the hollow body 20 of the machine. The shorter upper cutter-bar 32 is connected to the lower one by guideblocks 44 fitting in dovetailed grooves having enlargements 41 at the ends. The guide-blocks 44 are provided with screwed stems 43 on which fit spring washers 46 and annular nuts 47 in recesses in the cutter-bar 25. The nuts 47 are locked by spring pawls engaging teeth on their peripheries. A lubricating-channel 42 in the bar 25 communicates with the slots 40. The cutterbars 25, 32 have integral coacting teeth 26, 36 bevelled and tapered as shown. The outer edges of the outer teeth are vertical and' in line with the direction of travel so that they may operate close to walls &c. The bottom faces of the lower teeth 26 are bevelled upwards from the back to the front. In the extreme positions of the movable cutter-bar 32 the corresponding end teeth 26, 36 coincide in plan. One arm 62 of a three-armed rocking piece fits into a recess in the upper cutter-bar. The rocker is oscillated by the engagement of pawls 67, Fig. 7, with lugs 64 on the inner peripheries of the ground wheels. The pawls are pivoted on studs 66 and are provided with projections 68, 69 which engage the rocker arms and allow limited movement in one direction, so that the cutter may not be operated when the machine is drawn backwards. The body part 20 fits within flanges 55 in circular plates 56 mounted loosely on reduced parts of the axle 65. The ground-wheels are mounted on the squared ends of the axle 65 and are secured by nuts 74. The rear supporting-roller 82 is carried by arms 84 keyed on a rod 85 which is mounted in brackets 86 on the plates 56. The adjacent faces of the arms 84 and brackets 86 are serrated and bite into interposed yieldable washers 90 when drawn together by clamping-nuts 91. By this arrangement, the two ends of the roller 82 are always adjusted equally for varying the height of cut. The handle-bar 96 fits into a socket 95 in a head 94 mounted in sockets in the brackets 86.

Patent GB-323475-A (GB)
Title: Improvements in the manufacture and production of organic acids
IPC: C07C51/12
Filed: 1928-09-01
Abstract: 323,475. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 1, 1928. Grant. of Patent revoked. Organic acids and esters; acetic acid.-In the production of organic compounds, particularly acids and esters, by the action of carbon monoxide, preferably under elevated pressure, at an elevated temperature, on alcohols, esters, ethers or aldehydes, catalysts of the nature described in Specifications 254,819 and 320,457, the superficial area of which has been increased by the removal of one or more of their constituents by chemical or physical means, are used, particularly such catalysts as do not undergo reduction under the conditions of working. The catalysts may be prepared, e.g. from a mixture of chromium oxide and aluminium oxide, or of cerium metaphosphate and antimony metaphosphate in a current of phosgene or chlorine, or of gases containing these substances, whereby the aluminium and antimony are wholly or partially converted into their readily volatile chlorides. The catalysts may also be prepared from substances which contain constituents which are readily volatilized such as hydroxides which become oxides when heated, substances containing water, ammonia or alcohol of crystallization, or acid orthophosphates which give off water and become metaphosphates when heated. Activating materials such as potassium fluoride, sodium chloride, potassium iodide or aluminium chloride may be added. The presence of even traces of metals which form volatile carbonyls under the working conditions must be prevented. The walls of the vessel must be inert to the resulting organic acids and are consequently made of special bronzes containing, e.g., 8-10 per cent of aluminium and 1.5 to 2.5 per cent of silicon or manganese in addition to copper, or a coppermanganese alloy with 6-13 per cent of manganese. A copper alloy with a content of 6 per cent of silicon and 2.5 per cent of nickel is also suitable, or the reaction vessels may also be advantageously lined with chromium plated or silver plated or argentiferous material or glass. In an example cerium dioxide containing antimony pentoxide is introduced into phosphoric acid at 200‹ C. and the resulting melt is heated further until it solidifies. The cake is powdered and treated with phosgene at 400‹ C. until the major portion of the antimony has distilled as chloride. The residue is treated with a gas containing carbon monoxide for the production of acetic acid. Specifications 283,989 and 323,513 also are referred to.

Title: An improved inductive transducer for electrical transmission of mechanical magnitudes
IPC: G01D5/22
Filed: 1948-09-28
Abstract: 646,415. Electric indicating systems. LANDIS & GYR SOC. ANON. Sept. 28, 1948, No. 25305. Convention date, Oct. 15, 1947. [Class 40 (i)] In a transducer for electrically transmitting mechanical magnitudes, self-supporting rectangular coils 1, 2, Figs. 1, 2, are insulatedly attached to a. balance beam 5 pivoted about a shaft 6 to move alternately in and out of two pairs of airgaps between the poles of E-shaped electromagnets 12, 13 energized in series from an A.C. source. The coils are series opposed and connected to terminals through spring leads 7, 8 which control the rotary movement in conjunction with a metal band 23 encircling at one end a roller mounted on the shaft and attached at the other to a plate spring 27. The balance coils are connected in series with the current coils of a Ferraris relay (not shown) and when the beam is horizontal the relay is de-energized and remains neutral. Deflection of the beam in either direction by a mechanically-operated feeler operating to deviate the plate spring or rotate the shaft induces a coil voltage in the appropriate direction and energizes the relay to make one or other of its side contacts and operate known regulating apparatus. The winding surfaces are wider than the magnet poles, so that a maximum winding length is exposed to the field and the induced voltage is linearly related to the angular deflection of the balance beam. Guard plates 31, 32 protect the balance coils, and magnetic controlling plates 33, 34 enable unbalancing errors to be compensated.

Title: Method and apparatus for manufacturing a sheet material surfaced with thermoset synthetic resin
IPC: B32B38/08
Filed: 1953-09-14
Abstract: 760,931. Laminated and coated paper, fabrics, etc; coating webs. MARIAN, J. Sept. 14, 1953 [Sept. 12, 1952; Sept. 12, 1952], No. 25317/53. Classes 96 and 140. Sheet material having a hard, resistant surface is made by coating one face of absorptive sheet material such as paper or fabric with a thermo-setting resin in liquid state which penetrates only partly through the sheet, drying, with the aid of heat, subjecting the still hot or reheated material to heat and pressure to cure the resin, and immediately winding the material into a roll with the impregnated surface facing outwardly. Alternatively, an impregnated strip and an mitreated strip of absorptive material may be brought together and subjected jointly to the drying and curing steps whereby they are united together, and the resulting laminated strip is wound into a roll with the resin-treated surface on the outside. An adhesive-coated metal strip may be interposed between the impregnated and unimpregnated strips. The surface of the absorptive sheet that is to be exposed to view may be decorated or printed. The impregnating resin may be melamine- or urea-formaldehyde while the adhesive for coating the metal strip may be an aqueous emulsion of polyvinyl chloride-acetate resin to which may be added, a phenol- or urea-aldehyde resin. As shown, a web 14 of alpha-cellulose paper that has been impregnated by immersion in a liquid urea-formaldehyde resin and then surfacecoated with an aqueous solution of a melaminealdehyde resin, a web 58 of aluminium coated on both sides by immersion in an aqueous emulsion of polyvinyl chloride, and an untreated web 88 of paper, are led upwards from the treating and unwinding room through slots 84 into a drying and curing chamber with heatinsulating walls 96. The webs come together and are carried jointly by a tensioned band of steel or wire-reinforced rubber, which may be gas-permeable, past two series of hot-air nozzles 130. Hot air may also be injected at 126 and allowed to escape at 128, while additional heat may be applied by infra-red lamps 136 and electric heaters 138 and 140. The combined web passes under pressure rollers 144, is cured while passing between the band and a heated drum 100, passes around some of the rollers 144, through smoothing rollers 154, and out of the chamber through a slot 156. After trimming by a circular knife 160, the web is wound while still hot into a roll 168 with the impregnated surface facing outwards. The impregnating, combining, drying, curing, and winding-up steps may be separated, e.g. when using a flat press with heated press platens.

Title: Methods of and apparatus for coating filamentary materials
IPC: B05D7/20
Filed: 1947-09-18
Abstract: A core filament, e.g. a wire 16, is coated with a liquid, hardenable material to which it does not adhere by passing the filament through a smaller tube 12 having a discharge nozzle 14 and which projects into the enlarged upper end of a larger tube 10, and flowing the coating liquid 22 through the smaller tube and a carrier liquid 18, through the larger tube under such conditions in relation to the speed of the filament as to obtain viscous flow, the coating liquid becoming hardened about the filament during its passage through the unenlarged portion of the tube 10. The coating is subsequently removed from the core filament to form a hollow filamentary structure.  Centering spiders 32 may be incorporated in the tube 12. The carrier liquid, admitted to the tube 10 from a supply 20, serves to confine the coating <PICT:0663518/IV (a)/1> concentrically about the filament, may also by chemical or physical action effect the hardening of the coating liquid, and is collected in a sump 26 from which it may be recirculated.  The coating liquid may be latex in which case the carrier liquid is heated glycerine and a heater 30 is included in the return pipe to the supply 20, or the coating may be emulsions or dispersions of plasticised vinylacetate-vinyl chloride copolymer, plasticised polystyrene or polythene and the carrier liquid will destabilise the emulsion to precipitate the solid phase upon the wire.  The core filament may be single or multiple stranded metallic wire (copper is mentioned) or single or multiple threads of textile material, natural or synthetic rubber, resins, plastics or glass fibres and the coating liquid may be natural or synthetic rubber, natural or synthetic resin, cellulose derivatives or waxes, asphaltic materials, paints or lacquers.

Title: Improvements in and relating to vehicle buffers
IPC: F16F1/36
Filed: 1963-06-27
Abstract: 1,043,167. Vehicle buffers. GEORGE ANGUS & CO. Ltd. June 27, 1963 [July 6, 1962], No. 25595/63. Headings B7J and B7T. [Also in Division F2] A vehicle buffer comprises principal layers 9 of cellular elastomeric resilient material such as polyurethane, and secondary layers 10 of the same material but of greater density or finer cellular structure and therefore possessing different characteristics of compressibility and deformation. In a simple form of buffer, however, each secondary layer may consist of hardened adhesive securing the principal layers together, or the secondary layers may be of textile, metal or plastic material. The layer 9 next to the base-plate is stuck thereon and the end layer 9<SP>1</SP> may be provided with a protective coating 11. Through holes or blind heat dissipating cavities such as 12 may also be provided. In Fig. 3 (not shown) the layers 10 may be of smaller circumference than the layers 9 to provide circumferential grooves, and in Fig. 4 (not shown) the buffer tapers towards its front end and the layers are curved. In Fig. 5 (not shown), the secondary layers decrease in thickness towards the buffer front, but the principal and/or secondary layers may be of different thicknesses. In Fig. 6 the secondary layers 19 or the layers 9 may be wedge-shaped to prevent drooping of the buffer under its own weight. In Fig. 7 (not shown) the layer 9 nearest the base-plate 7 is of greater diameter than the other layers and is held thereto by adhesive and an annular plate having flanges extending over the edges of the layer.
