Title: Improvements in or relating to cutting machines
Inventor: GLOVER WILLIAM GEORGE
IPC: B23K7/00
Filed: 1955-08-31
Abstract: 793,199. Cutting by fusion. BRITISH OXYGEN CO., Ltd. Aug. 30, 1956 [Aug. 31, 1955], No. 25039/55. Class 83 (4). A cutting machine, particularly a flamecutting machine, has a first cutting head 5 movable under the control of a template 6 and a second cutting head 13 movable in a linear path, the movement of the first cutting head being resolved into two mutually perpendicular directions one of which is parallel to the linear path of the second cutting head, and means are provided for varying the speed of the second cutting head in dependence upon the second component of resolution. The template 6, which may be of magnetic material, is disposed between two rails 2 along which run carriages 3 connected by a transverse beam 1. A boom 4 movable lengthwise of the beam 1, carries the cutting head 5 and a tracing head 7 which may be a magnetized follower wheel driven by a motor. An endless chain or cable 16 passing around spaced jockey pulleys 15 on the beam is connected at 17 to the boom 4 and drives a pulley 18 mounted on a bracket 19 adjustably clamped to the beam 1. Pulley 18 carries a pinion 20 meshing with a rack on a slider 14 carrying the second cutting-head 13 and movable parallel with the rails 3. Thus, transverse movement of beam 17 drives chain 16, pulley 18 and pinion 20 which thus moves the slider 14 longitudinally. Pulley 18 may be stepped for varying the speed relationship. The beam 1 is preferably extended beyond the left rail 2 and carries a second set of cutting heads whereby two plates 10 may be cut simultaneously. Alternatively the first and second cutting heads may be interconnected for corresponding movement by two perpendicular racks meshing with a single pinion. The second cutting head may move along a bar such as 14 fixed to the beam 1.

Title: Process for preserving wood
IPC: B27K3/12
Filed: 1935-09-09
Abstract: 462,597. Preserving wood. RAYNER, G. F. (Osmose Holzimpraegnierung Ges.) Sept. 9, 1935, No. 25065. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 30, 1936.] Drawings to Specification. [Class 140] Freshly-cut timber is preserved by removing the bark, coating the surface with an aqueous paste containing a water-soluble preservative, and covering the coated wood with a windproof and waterproof covering to retard drying until the preservative has diffused into the wood to the desired depth. The covering may be of any suitable material, e.g. sheet iron, paper, fabric, straw, &c., the wood being closely stacked before covering. Suitable preservative agents are water-soluble inorganic substances, e.g. potassium fluoride or zinc chloride together with fungicides, e.g. copper sulphate, potassium sulphide, mercuric chloride, zinc fluorsilicate, and insecticides, e.g. potassium arsenite or potassium arsenate. Two or more soluble inorganic substances, capable of reacting within the wood to form an insoluble product, may be employed, e.g. a fluoride or arsenate with a dichromate. The preservative substance is formed into a paste with starch, casein, glue, gelatine, agar agar, or gum arabic. A waterinsoluble, organic protective agent, e.g. dinitrophenol, dinitrocresol, tar oils or liquid petroleum may be applied to the wood after application of the preservative and before or after the wood has become air dry, or it may be incorporated in the paste. Examples are given of pastes including dinitrophenol. Specification 381,030 is referred to.

Patent GB-674519-A (GB)
Title: Improvements in the production of moulded articles from polyethylene
IPC: B29C45/00
Filed: 1950-10-17
Abstract: Foils, plates, or other articles are obtained by a process in which polyethylene is moulded in fused condition under sub-atmospheric pressure which is low enough to allow the volatile ingredients to escape from the melt, e.g. it is heated to 150 DEG  C. and cast at 740 mm. mercury.  The material may be fused in the mould, or fused outside the mould and poured thereinto.  In an example, pulverulent, granular or lumpy polyethylene is charged into a horizontally-arranged mould for a plate and melted therein under 10 mm. mercury.  Colouring material, graphite and other fillers may be added.

Title: Pulse edge coincidence detection circuit for digital data  transmission
IPC: H04L7/00
Filed: 1974-06-06
Abstract: 1469860 Data transmission; synchronizing L M ERICSSON PTY Ltd 6 June 1974 25255/74 Heading H4P To avoid coincidence of transitions between incoming data and clock pulses, which would result in information becoming lost, if coincidence occurs compensation is made if coincidence is detected by delaying outgoing data, on which timing of incoming data is made dependent. Incoming data on line 10, from say an exchange, is dephased by local clock 13 in apparatus 11 and through D type flip-flop 15 is clocked to line 12 at double clock frequency from line 14. Data received (by e.g. the exchange) from a remote terminal on line 18 primes D type flipflop 20 so that low, e.g. quarter frequency clock pulses on line 24 are passed through. The low frequency clock on line 25 passes through OR gate 21, also connected to the reset output of flip-flop 20, the set output priming exclusive OR 22 which receives a double frequency clock from line 14. Positive transitions on line 18 cause flip-flop 20 to pass transitions appearing on line 24. If line 24 is high at a positive transition, if flipflop 20wasina reset state, it becomes set, output 27#1 and 26#0. If the original condition of FF20 is reset, the true/signal will appear at 24 but after change of state to set, it will be inverted due to OR 21. FF20 would again change state at next occurrence of positive transition of incoming data coinciding with clock pulses but this is prevented by OR 22 which inverts the double frequency clock pulse which clocks the positive edge through FF20 and causes outgoing data to be delayed. A remote terminal will resynchronize on the delayed outgoing data and a further clash of data and clock pulses will only occur if propagation delay changes.

Title: Improved treatment of films and foils of cellulose esters
IPC: F16J15/06
Filed: 1932-09-12
Abstract: Films or foils containing a softening-agent and made from cellulose esters, mixed esters, and ether - esters containing an aliphatic carboxylic acid radicle having up to five carbon atoms, in particular, cellulose acetate, are improved as regards their mechanical properties while preserving a normal sensitiveness to water, by partial saponification on one or both faces to an extent at least one-sixth of the thickness of the film, by treatment with an alkaline liquid capable of dissolving the softening agent. After the saponification has proceeded to the desired depth, the alkaline liquid is removed by washing with a liquid having no solvent action on the softening agent, for instance, with acetic acid, alcohols, and mixtures of water and alcohols.  The saponified films are suitable as photographic supports.  The softening agent may be, for example, vinyloctodecyl ether, toluene sulphonamide, paratoluene sulphoethylamide alone or mixed with diethyl phthalate, carbamic acid ethyl ester, or ethyl acetanilide, or resins or synthetic resins such as ureaformaldehyde resin.  In examples, the saponifying liquid is a solution of ples, the saponifycresols, chlorocresols, xylenols, naphthols, resorcinol monoalkyl ethers, oxynaphthoic acid esters or other derivatives of oxynaphthoic acid.  The reaction may be carried out by dissolving or suspending the sulphophthalic acids or their derivatives in the tertiary base and heating the solution or suspension with the phenolic compound.  If the ester is to be obtained by way of the halide, this may be produced during the reaction by means of phosphorus oxychloride.  The products are wetting, cleansing, and emulsifying agents and may be used in the textile industry alone or together with soaps, substances resembling soaps or solvents.  In many cases, particularly if the phenolic residue contains halogen, they are excellent agents for the protection of animal fibres against insect and cryptogamic pests.  In examples: (1) b -sulphophthalic anhydride (obtainable by heating the free acid in vacuo) is dissolved in pyridine and the solution is heated with b -naphthol and phosphorus oxychloride; the product causes very easy wetting in water; (2) a similar reaction is carried out using hydroquinone monoethyl ether; the product may be employed as wetting agent in a carbonizing vat; (3) a similar reaction is carried out using o-chlorophenol; the product has a remarkable wetting power, e.g. in a carbonizing acid; the o-chlorophenol may be replaced by p-chlorophenol, a chlorocresol or dichlorophenol.

Title: Improvements in machine and method for attaching closuring fasteners to flexible sheet material casings enclosing food products
IPC: B65B51/04
Filed: 1959-07-24
Abstract: 912,591. Seals and sealing. KELEM, H. July 24, 1959 [July 24, 1958; Aug. 19, 1958], No. 25556/59. Class 146 (2). [Also in Group XVII] A device for sealing the gathered or twisted mouth of a film casing for food products, comprises means to compact the gathered mouth and bend a metal fastener to loose ring formation about it, and means to indent the ring to secure the fastener. The device comprises a fixed anvil 23 with side plates 36, 37, and a sliding member 31 with plates 44 which co-operate with the plates 37 to confine the already gathered mouth, placed on a supporting surface 34, at two spaced circumferential positions. Fasteners 16 are fed from a hopper 81 in front of a driver 60 sliding in the member 31, the driver being bored to receive the indenting tool 65. When a casing mouth has been placed on the support 34, air is admitted to a cylinder 54 causing a piston-rod 53 to engage a roller 52 which, through linkage 47, 49, advances the member 31 until the rod slips beneath the roller, at which time the mouth has been confined. A roller 70 on the rod 53 rotates a pinion 68 to move forward the driver and indenter, the latter remaining retracted within the driver until the latter forces the fastener against the anvil so that it forms a complete ring round the casing mouth between the confined portions. The indenter is then advanced by continued rotation of the pinion, to deform the ring. The degree of deformation may be adjusted by a scroll cam 75 which limits the movement of the rod 53. Fastener feed.-Fasteners are stored randomly in the hopper 81 but are caused to arrange themselves astride a feed shoot 82 by a blast of air (the exhaust from the cylinder 54) entering the hopper through a pipe 91. A lip at the entrance to the feed channel 62, causes them to turn on entering it. In another embodiment (Figs. 16 to 19, not shown) the fasteners are stored in an intermittently rotated drum, the rotation causing them to arrange themselves on a shoot as before. A reciprocating pusher feeds them sideways into the driver path.

Title: Image Motion Stabilization System
IPC: G03B15/00
Filed: 1966-06-08
Abstract: 1,154,881. Television. ITEK CORP. 8 June, 1966 [8 June, 1965], No. 25589/66. Heading H4F. An image motion stabilization system employs photosenstiive means (e.g. an image converter, image intensifier or image orthicon tube) producing an image of an object and having image deflection means supplied from sensors responsive to motion of the photosensitive means to deflect the image in a direction to cancel motion of the latter caused by motion of the photosensitive means such deflection being inhibited when the angular motion of the optical axis of the system is slower than two revolutions per second. The invention is described in connection with stabilizing the image on the film of photographic cameras, in the eyepiece of telescopic rifle sights and on the target of television pick-up tubes against random angular motion of the optical axis of the apparatus. The sensors, which provide signals indicative of the sign and magnitude of motion (i.e. instantaneous position) in rectangular coordinate directions X, Y, comprise rate gyros 13, 17 (Fig. 1) with associated integrating amplifiers. In the case of the hand held camera arrangement of Fig. 1 resistors 15, 20 are shunted across the integrating capacitors 16, 19 of the integrating amplifiers to prevent the image deflecting means from responding to signals (of about 2 c.p.s.) produced by slow panning. The image converter may be sensitive to infra-red radiation to allow night photography to be carried out. The arrangement of Fig. 1, less the lens 5 and photographic film 6, may be mounted on a rifle to stabilize the image produced by a telescopic objective lens forming part of the rifle sight (Fig. 3, not shown) and the basic elements of Fig. 1, specifically the rate gyros with their associated integrating amplifier circuits, may be mounted on the supporting framework of an image type television camera tube, e.g. of the image orthicon type, to stabilize the image on the target thereof (Fig. 4, not shown). The rate gyro circuits are described with reference to a schematic arrangement (Fig. 2, not shown).

Abstract: 727,505. Resistance coatings and deposits. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Oct. 13, 1953 [Oct. 14, 1952], No. 25746/52. Class 37. A glass or other insulating support has a main and an auxiliary resistance coating. The main resistance coating is covered by an insulating coating and both these coatings are applied by evaporation by heat in a vacuum. The two resistance coatings are in series and the total resistance is adjusted to the required precision value by removal of an appropriate quantity of the auxiliary coating. The latter is of good stability when in contact with the atmosphere. In Fig. 1 the auxiliary coating 5 is of noble metal (e.g. an alloy of gold and platinum) and overlaps terminal deposits 2, 3 and the main coating 6 (e.g. an alloy of nickel and chromium) overlaps terminal deposits 3, 4. A layer 7 of magnesium fluoride, Fig. 2, insulates and protects the main resistance coating 6. The removable or adjustable auxiliary coating 5 provides only a minor part (e.g. 5 per cent) of the total resistance. In a modification, Fig. 3, the terminal layers, 3, 3, are omitted and a single layer 9 of noble metal is used. Instead of glass strip as at 1, glass tube may be used as the insulating support. The terminal layers are of silver and these and the noble metal auxiliary coating are painted on and then fired. During the processes of applying the main resistance and insulating coatings the auxiliary resistance coating is shielded from the successive vapour streams by a screen close to the glass strip but preferably not touching it.

Abstract: 1488506 Adjusting vehicle headlamps BRITISH LEYLAND UK Ltd 11 June 1975 [11 June 1974 21 March 1975] 25753/74 and 11823/75 Heading F4R [Also in Division F2] A spring/dashpot device which absorbs rapid movements but allows slow movements comprises an input rod 30 with an end portion 31 acted on by springs 29a, 29b in a hollow piston 21, the hollow piston 21 being fixed to an output rod 32 and sliding in a cylinder 20 to define two fluid filled chambers 26, 27 interconnected by a bleed path 28. In operation the cylinder 20 is fixed, and rapid movements of the input rod 30 are absorbed by the springs 29a, 29b without transmission to the output rod 32 because movement of the hollow piston is damped by the bleed path 28. Slow sustained movements of the input rod 30 are however transmitted to the output rod 32. The device is used as a link in a vehicle headlamp levelling system e.g. that of 1,457,413 (Fig. 1, not shown) to ensure that the system responds only to changes in vehicle attitude consequent on static load changes. In modifications of the device the hollow piston is open to the fluid chamber 26; the end portion 31 of the input rod 30 is formed with large apertures so that its movement is not retarded; and the input rod 30, rather than an extension 24 of the hollow piston, extends through the seal 25.
