Title: A method and apparatus for uniting superposed fabric webs by blind-stitching
IPC: D05B1/24
Filed: 1952-12-04
Abstract: 721,794. Compound fabrics; folding fabrics. JONSSON, N. J. Dec. 4, 1952 [Dec. 8, 1951], No. 30791/52. Classes 42 (2) and 140. [Also in Group VII] Two or more lengths of fabric to be united together are superimposed and sewn up at their ends to form an endless band which is blindstitched along its entire length and width by successively applying a plurality of parallel lines of stitches running lengthwise of the band. With wide fabrics, half the width is stitched from each edge. The superimposed fabrics 5 are pulled over a work-table 1 and under a roll 37 by a rubber-covered feed roll 13 and are piled in folds in a movable receptacle 35 by a swinging-arm device 33. The leading end of the assembled fabrics is withdrawn through rolls 36 forming the bottom of the receptacle, led around a rubber-covered feed roll 12 and roll 38 on to the work-table where it is stitched to the rear end of the assembled fabrics to provide an endless band which is blind-stitched by a machine 2. The band is guided by hand so that properly spaced stitch lines are applied over the whole width without stopping the machine. The fabrics are pressed against rolls 12 and 13 by weight-biased discs 18 and 19. Garment parts, e.g. undercollars comprising the undercloth and intermediate lining of the collar of a costume, may be cut directly, to their final size, from the compound fabric.

Title: A process for the protection against fouling and corrosion of ships' hulls, metal sheet pilings and like objects
IPC: B63B59/04
Filed: 1954-10-26
Abstract: 754,812. Preventing incrustation and corrosion. VELDE, J. C. VAN DER. Oct. 26, 1954, No. 30827/54. Class 123(1) Fouling and corrosion of ship's hulls, sheet piling &c in sea water is prevented by passing a direct current between copper anodes and the immersed structure, the toxic copper compounds formed electrolytically at the anodes flowing over the metal surfaces and preventing growth of molluscs, &c. thereon whilst the current flow provides cathodic protection for the surfaces. Preferably iron anodes with copper inlays are used. To protect stationary structures such as lightships, the anodes are secured to projecting carriers. For moving ships they are applied against the hull and insulated therefrom, the insulant enclosing the anode except for its outwardly facing surface. A visual or acoustic signal operated by the cessation of the current supply is provided and may be combined. with an arangement for switching over to another source of current so as to provide continuous protection. Specification 534,029 is referred to.

Title: Silencers for pneumatic tools
IPC: B25D17/12
Filed: 1972-07-03
Abstract: 1386288 Silencers for pneumatic tools S WILMAN 3 July 1972 [5 July 1971] 30965/72 Heading B4C [Also in Division F1] A silencer for the exhaust of a pneumatic drill or the like comprises an outer casing 2, 3 which is adapted to surround the tool body 1 and has its internal cavity divided into a plurality of chambers 13, 13<SP>1</SP>, 14, 15, 16, 17, 18. Resonators are formed by the chambers 13, 13<SP>1</SP> connected to the chamber 14, adapted to receive exhaust air from the body orifice 20, by a tube 52 and openings 53, 54, respectively. At least one pair of successive chambers 14, 15 and 16, 17 through which the air flows in opposite directions are connected by a series of orifices (21 to 28), Fig. 3 (not shown), and (32 to 38), Fig. 5 (not shown), of increasing cross-sectional area in the direction of air flow in the upstream chamber to provide interference of the sound waves in the pair of chambers. The resonator 13 is tuned to the predominant frequency in the range from 0 to 1600 Hz. The reversal of air flow direction in successive chambers is effected by a partition 29 extending through the chambers and the provision, adjacent the partition, of outlet orifices (30, 30, 41, 42), Figs. 4 and 6 (not shown), from the downstream chamber of each pair. The air escapes from the casing 2, 3 through orifices 46, 47, 48 (43, 44, 45), Fig. 7 (not shown), which increase in cross-sectional area in the direction of air flow in the chamber 18 and produce sound wave interference. The casing may have two partitions 29 which define two series of successive communicating chambers adapted to receive exhaust air from at least two orifices in the body 1. A cylindrical sleeve of sheet metal may be fixed to the partitions 9 ... 12 to surround the body 1 and define therewith a resonance chamber or a path for air from chambers between the partitions. The casing 2, 3 may be formed of light alloy or rubber and may be of cylindrical, egg or vase shape or formed of two frusto-cones joined at their bases. The casing may be elliptical in cross-section.
Patent GB-1109648-A (GB)
Title: Heat storage apparatus
IPC: G05D23/19
Filed: 1965-07-21
Abstract: 1,109,648. Automatic temperature control. COMSTOCK & WESTCOTT Inc. July 21, 1965 [Aug. 24, 1964], No. 31003/65. Heading G3R. [Also in Division F4] The air temperature in the outlet duct of a thermal storage space heater of the type disclosed in Specification 1,109,649 (and see Fig. 1, not shown) is regulated by a control system responsive to a bulb thermostat 47 in the outlet duct. Too high an air temperature causes expansion of bellows 24 which actuates a motor 46' to rotate a valve 33 in the cold air inlet to the heater, in an anticlockwise direction. This reduces the air flow through the heater and increases the air flow bypassing the heater so reducing the temperature of air in the outlet duct. Too low an air temperature causes contraction of the bellows 24 and clockwise rotation of the valve 33 by the motor 46' whereby the air flow through the heater is increased and the air flow by-passing the heater is reduced. To maintain the air temperature in the outlet duct within a narrow range the action of bellows 24 is partially opposed by a solenoid 26, the current supply to which is increased as the valve 33 turns clockwise and decreased as it turns anti-clockwise by means of a sliding contact 45' which turns with the valve 33. The control system also includes means to turn the valve 33 to a position Fig. 2 (not shown) whereby no air can flow through the heater when the demand for heat at a location P Fig. 1 (not shown) ceases. This prevents the heater delivering excessively hot air due to initial lag in the thermal elements when starting again. On the room space P requiring heat, thermostatic switch 50 closes. As switch 55 is already closed, as will be explained, relay 53 is energized from the position shown, to a position wherein contacts 34 and 59 make, causing operation of the hot air blower 41, contacts 56 and 60 make, causing opening of louvres in the heater by means of solenoids 51 and 52, and contacts 57 and 61 make so that relay 53 remains energized whilst switch 50 remains closed, whatever the position of switch 55. The outlet air temperature control then operates in the manner described above. When the demand for heat at space P ceases, thermostatic switch 50 opens and relay 53 is de-energized the contacts returning to the position shown. The hot air blower is therefore stopped and the louvres in the heater closed. In addition contact 54 now makes with contact 58 to energize a heater 56' associated with the bulb thermostat 47. This causes bellows 24 to expand so that motor 46' turns valve 33 to a position wherein the cold air inflow would all by-pass the heater were the hot air blower operating Fig. 1 position (not shown). Only when the valve 33 reaches this limiting position does switch 55 close to permit the thermostatic switch 50 to initiate the next heating cycle.

Abstract: 1446336 Helicopter rotors SUMMA CORP 2 July 1973 [17 July 1972 18 April 1973] 31453/73 Heading B7W [Also in Division F2] Hollow helicopter rotor blades and ducts for gas turbines are provided internally with allmetal thermal insulating material which may also be applied externally to honeycomb construction aerofoils or to exhaust gas ducts. The all-metal insulating material comprises two perforate or imperforate metal skins spaced by and fixed to a member comprising at least one metal wire mesh, optionally in combination with a perforate metal foil serving as a radiation shield, the spacing member spacing the skins by a distance greater than the thickness of the mesh or mesh and foil combination and dividing the space between the skins into cells which intercommunicate to permit fluid pressure equalization throughout the space. The skin sheets may be of wire mesh or perforate or imperforate foil and may be dimpled, corrugated or otherwise deformed; while the spacing member may be formed by one or more dimpled or corrugated wire mesh or metal foil layers, a flat wire mesh together with a corrugated perforated foil, or tubes of metal mesh disposed axially perpendicular to the skin sheets. In one arrangement the "hot" side of the insulation is provided with a multiple layer laminate of alternative imperforate foils and wire meshes. The various layers of the insulation material may be connected together by spot-welding and the insulation may be similarly secured to the body to be insulated. If foils are not used the insulation components may be stitched together with wire. The cells between the skins may be filled with non-flammable metal wool. In a modification the all-metal insulation is formed by a perforate or imperforate metal skin to which is affixed tubes of metal wire disposed with their axes parallel to the skin, the tubes being either in a single layer with adjacent tubes contacting each other or in two layers of spaced tubes, one layer containing the skin and the other disposed so that each of its tube contacts a pair of tubes in the other layer. When used internally of ducts the skin exposed to the high temperature fluid may be imperforate. A self-supporting structure of metal mesh materials may be used as fire walls for fuel tanker or engines on aircraft. Typically the components of the insulation are formed of stainless steel -but if necessary are of refractory metals such as molybdenum or titanium. If insulated internally ducts in gas turbines usually formed of high temperature nickel alloys may be of aluminium. Ducts may be formed by insulating material welded longitudinally to form tubes. The metals employed may be coated with gold, platinum, chromium, copper, silver, rhodium, rhodium-iridium alloys, zinc, aluminium, nickel or brass to reduce emissivity and in certain cases oxidation. Specification 1,446,335 is referred to.

Abstract: 519,493. Electric battery lamps. ARDEN, T. R. Nov. 4, 1938, No. 32018. [Class 39 (ii)] A battery lamp is constructed to contain two sets of cells 60, of semi-cylindrical cross-section. Normally only one set is used to supply the lamp when the usual switch is closed. When this set is depleted, the other set is brought in circuit by a halfrotation . of the end-cap 45. Whereupon a "D" aperture in the cap 45 is aligned with a similar aperture in disc 44 and the exhausted set is expelled by a spring contact plunger 31. When. a new set is inserted in lieu of the exhausted set, the disc 44 is half rotated so as to retain the new set, which thereupon becomes the reserve set. When one set of cells is absent, the corresponding contact' plunger 31 prepares the circuit of an indicator lamp which is illuminated when the main lamp is energized so as to give a warning that the casing does not contain a reserve set. Alternatively the 'plunger 31 may operate a shutter to uncover an indicator window. By removal of the cap .45 a normal cylindrical type battery can be inserted in the casing in place of the special cross-section batteries.

Abstract: 1,221,151. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 25 June, 1969 [28 June, 1968], No. 32093/69. Heading H4K. Signals between an exchange network and a controlling processor are buffered in an interfacial system comprising a store for last look and command data. Each element of a buffer store in an interfacial unit corresponds to a possible test lead to the network such leads being scanned in sequence. A permanent store indicates which of the possible test leads is active in a process of comparing the test results currently present on the test leads with last-look information held in the corresponding elements of the store. Other elements of the store are used as digit registers and order registers. Any change of state detected in the last-look comparison results in a demand for the services of the processor. To connect one-and-only-one interfacial unit to the processor when a number of such units make demands for service concurrently, a two-stage switching arrangement is provided. The first stage comprises one- and-one-only selectors for respective groups of interfacial units and the second stage makes a one-and-one-only selection from among the competing demands of the first stage. To obtain access to an interfacial unit otherwise than by way of a demand originating in such unit, the processor sets the unit to a demanding state by way of a bus which resets all units before nominating one for demand. Response to such a simulated demand effects a connection to the processor over the two-stage switching arrangement. In its association with the peripheral units the processor has four modes which are, idle, receiving, transmitting and processing. The design of the interfacial units is said to be suited to large scale integrated circuit production.
