Title: Improvements in door lock
IPC: E05C1/16
Filed: 1955-11-01
Abstract: 777,028. Door locks. AMERICAN HARDWARE CORPORATION. Nov. 1, 1955 [June 6, 1955], No. 31138/55. Class 44. A door lock comprises a casing, a retractor 20 in said casing, a latch bolt 6a adapted to be retracted by said retractor, an inner and outer independently operable operating member 45, 46 for actuating said retractor, a longitudinally movable dogging bar 51 extending through said casing, dogging means 63 controlled by said bar for dogging said outer operating member against operation, means 52 accessible from the inner side of the lock for moving said dogging bar from undogging to dogging position, a projection 26 in said casing and resilient retaining means 68 carried by said bar adapted to embrace said projection when the bar is moved into dogging position to yieldingly retain said bar in said position. The casing and retractor 20 are identical with those disclosed in Specification 776,127, and the retractor operating means including the members 45 and 46 are identical with those disclosed in Specification 757,842, the means 45 and 46 being knobs secured to tubular spindles 38, 39. The dogging bar 51 is slidably mounted in the spindle 38 by means of an apertured disc 54 which is kept in engagement with ears on the spindle by the pressure of a spring 56 which is trapped between the disc and a push-button which is the means 52 accessible from the inner side of the lock since it is contained in an aperture in the knob 45. The dogging means 63 is part of a blade 61 which is carried by the dogging bar and when the push-button 52 is depressed, the means 63 enters aligned slots 41 to 44 in the spindle 39, a bushing 31, a retaining washer 37 associated with the spindle and in a cover-plate 14 respectively, so that the spindle is locked to the cover-plate and hence the rotation of the outer knob 46 is prevented so that the latch bolt cannot be retracted. The projection 26 is a pin carried by the retractor 20 and when the retractor is unoperated the pin enters a slot 59 in the retractor bar 51 and hence limits the movement of the retractor bar when it is moved.by depression of the pushbutton 52. When the push-button is depressed the pin is passed between humps 71 of a spring clip which forms the retaining means 68, the spring clip being secured to the dogging bar and being strong enough to hold the dogging bar in its dogging position against the pressure of the spring 56. The dogging bar is released either by rotation of the inner handle 45 which moves the retractor and hence the pin 26 from the slot 59 or if the dogging bar is in the operating position when the door is open, movement of the retractor caused by depression of the latch bolt by its keeper when the door is slammed moves the pin 26 from the slot 59 and hence frees the dogging bar. The dogging bar can also be moved from its operating position in which it locks the outer knob 46 by the insertion of a screw-driver or nail through an opening 74 in the knob 46 to engage an ear 60 on the dogging bar, pressure on the screw-driver or nail freeing the pin 26 from the spring clip 68.

Abstract: 769,343. Vehicle wheels. KELSEY-HAYES WHEEL CO. Oct. 28, 1954 [Nov. 16, 1953], No. 31195/54. Class 144 (1). To sound-deaden a bogie wheel having a body 1, comprising a radial web 4 with an axial outer peripheral flange 6 extending at one side thereof, and a rim 2 comprising a radial web 7, overlying the body web 4, and an outer peripheral axial flange 8 concentric with the body flange 6 and extending beyond its free end, a flanged ring 9 of resilient sound-deadening material such as rubber is sandwiched between the respective webs and flanges of the rim 2 and the wheel body 1 under radial compression so that the displaced material of the ring 9 forms a retaining lip 12 extending radially along the free edge of the body flange 6. The body 1 is thereby located axially within the rim by the rim and ring flanges 7, 11 respectively and the ring lip 12. Fig. 3 shows the wheel rim, with the tyre 3 and ring 9 bonded thereto, supported on a stationary outer die 13 and the wheel body 1 supported on an axially-movable inner die 14 and plunger 15. The die 14 extends through the rim flange 7 and prevents radially inward flow of the ring flange 11 during axial assembly movement of the wheel body so that all displacement of the ring material is axially outwardly to form the lip 12.

Title: Method and apparatus for taking x-ray photographs
IPC: A61B6/14
Filed: 1954-10-28
Abstract: 754,694. X-ray apparatus. PAATERO, Y. V. Oct. 28, 1954, No. 31231/54. Class 98 (1). A radiograph of a curved layer within an object is made by moving the object relative to a fixed X-ray source, and moving a film having substantially the same contour as the layer with the same linear speed as the layer, the X-rays being directed through the object, and then through means for restricting them to a narrow beam, on to the film. The method is described with reference to the radiography of the jaw. As shown in Fig. 1, a chair for a patient is supported on a dome 16 mounted on a base 1 for rotation by an electric motor 17 driving a gear mounted on base 1 and engaging teeth 19 on the inside of the base of the dome. Supports 23 fixed to the dome carry a neckring 24, centred on the axis of rotation of the chair, and having removable part 24a so that the neck of the patient can be inserted in the ring. A slide 27 is movable backwards and forwards in'a slot in a frame 25. Two ear rods 28 are threaded on a rod 29 which has oppositely threaded ends and is journalled in slide 27. Rods 28 slidably engage a rod 31 fixed to the'slide, so that by turning the threaded rod 29 the ear rods are moved outwards or inwards. The seat 20 is vertically adjustable by a hand wheel 21 to bring the patient to a height where the ear rods are adjusted to insert pins at their lower ends into the patient's ears. A frame 3 hinged at 2 to the base 1 supports a rod 4 carrying the rotatable cassette table 5 and fixed but adjustable shutters 12 defining a slot 13. A film support 6 is curved to the shape of the jaw and hinged for a degree of adjustment to allow for individual variations in the shape of the jaw, and has a rubber apron for holding a film to its curved surface. The film support is carried by the table 5 which, by its weight acting around pivot 2, is held in edge-to-edge contact with neck-ring 24 so that when the chair and patient are rotated, table 5 turns in the opposite direction. An X-ray tube (not shown) directs a beam through the patient's head and through slit 13 on to the film in holder 6. The jaw is thus scanned on to a film of similar shape moving at the same linear speed. Specifications 653,401 and U.S.A. Specifications 2,613,726, 2,684,446 also are referred to.

[Also in Divisions F2 and F4] Apparatus for controlling and cooling a gas comprises a duct having in flow series atomizing means for a cooling liquid, and a valve. The atomizing means comprises an aperture in a wall of the duct in a relatively low pressure area and leading to a liquid reservoir pressurized from a tapping in a relatively high pressure area of the duct. As shown, the gas duct 2 contains the movable closure member 46 of a valve and the liquid passes from a connection 52, through cooling passages 31 in the valve body, a chamber 32 through which an extension 41 closure member slides, and through bores 43 to one or more atomizing apertures 5<SP>1</SP> in a constriction of the duct formed by the member 46. The pressure on the member 46 is balanced by a duct 44 which provides communication between opposite ends of the member 46. This balancing may alternatively be provided by feeding cooling liquid to the chamber in the cover 36. The gas may be used to drive a turbine, or to provide a control jet on an aircraft, either producing direct thrust, or acting on a rocket motor exhaust to deflect it. The liquid flow rate may be varied by valve between the connection 52 and the reservoir.

Abstract: 332,834. Telefunken Ges. fiir Drahtlose Telegraphie. Oct. 15, 1928, [Convention date]. Thermionic homodyne receivers.-An auxiliary frequency, such as is used for example to effect automatic gain control, is made to serve the further purpose of synchronizing the frequency of a local oscillator employed at the receiving end to re-introduce a suppressed carrier wave. The homodyne generator 3 is coupled to the receiving amplifier and rectifier 2. The auxiliary frequency is accepted by a filter 5 and is fed to two amplifiers 8, 9 in push-pull through a transformer 6, and simultaneously in parallel through a transformer 7. The circuit 6, 10 is tuned to the auxiliary transmitted frequency, so that if the local frequency supplied by the generator 3 is the same as that transmitted, the voltages applied to the grids of the valves 8, 9 by the transformers 6, 7 will be 90‹ out of phase, the plate currents from both valves will be equal, and a relay 11 remains unaffected. If the two frequencies are different, however, the relay 11 is operated to place a positive or negative bias on the grid of a valve 12, which, in turn, detunes the circuits of the generator 3 until exact synchronism is attained.

Title: Improvements in the manufacture of metal tubing
IPC: B21C37/10
Filed: 1938-11-01
Abstract: 520,767. Making compound tubes. ARMSTRONG, J. J. V. (American Rolling Mill Co.). Nov. 1, 1938, No. 31556. [Classes 83 (ii) and 83 (iv)] Soldering-In making tubes from strip metal stock with juxtaposed parts in one or more seams of plies or both, a sealing metal of low melting point and a sealing metal of high melting point but below the melting point of the strip are separately introduced in proximity to the juxtaposed parts, and the whole is subjected to a temperature materially above that of the melting point of the former sealing metal but below that of the latter, to cause the former to melt and alloy with the latter and unite the parts, which are then cooled. The strip may be formed of ferrous metal or of copper, nickel or other nickel alloy and the sealing metals may consist of copper and tin, copper and zinc, copper and nickel or other metals. The copper itself may contain other alloying metals. A single ply tube, with a lock or lap seam may thus be made or a multi-ply tube formed either from two separate strips with individual butt seams or from a single strip with an offset. A double ply steel tube formed from two strips may have the outer tube 1, Fig. 6, coated at 5 with tin and the inner tube 2 coated at 6 with copper. The coatings may be applied by heat or electrodeposition, the quantity of tin being preferably low compared with that of copper. The assembled parts are then passed lengthwise through a guide tube 41 in a furnace at about 1650‹F. to 1830‹F. and containing a non-oxidizing gas and thence pass through a cooler 42. The furnace may be replaced by an electric heater. The tin melts at about 450‹F. and alloys progressively at 7, Fig. 7, with the copper and diffuses into the plies to join them together and some of the alloy also flows into the seams 3. The tube may also be coated with copper on its inside or outside surface or both prior to the heat treatment, the coating remaining unmelted during the heat treatment but diffusing in the solid state into the steel. If desired the coatings 5, 6 may be superposed on the inner or on the outer ply instead of being applied one on each ply. When making double ply tubes from a single strip the strip may be coated on both sides first with copper 14, Fig. 9, and then with tin 15. The heat treatment results in a double ply tube bonded between the plies and provided with inner and outer coatings of bronze. A coating 21 of copper may be applied to one edge of a lock joint, Fig. 11, and the tin supplied at 22 in the form of a wire, strip, ribbon or foil. Similarly one or more of the surfaces of the plies 1, 2, Fig. 12, of a double ply double-strip tube may be coated with copper and the tin introduced at 25 either as a wire, strip or foil or as a powder carried by a binder. The composition and thus the melting point of the resulting alloy may be predetermined by adjustment of the relative quantities of the two sealing metals.

Abstract: 1,159,601. Laminated non-woven webs. JOHNSON & JOHNSON. 14 July, 1966, No. 31710/66. Heading B5N. [Also in Division D1] A non-woven web comprises individual synthetic textile filaments of from 1-10 denier, each having an irregular sinuosity presenting looped portions which overlap and engage looped portions of adjacent filaments, the individual filaments in a unit section of the web each having a length in its sinuous form substantially equal to that of the unit section, and in its straightened form substantially equal to that of the associated filaments, the web being substantially uniform and the filaments all lying in the same general direction. The web is made by presenting a tow of synthetic filaments to a liquid flowing through a chamber to convey the tow through the chamber, the liquid moving faster than the tow to maintain the tow under tension, uniformly applying divergent forces to the tow while in said liquid to spread the tow into a web, and collecting the filaments at a slower speed than the speed of the tow in the liquid whereby the filaments assume a sinuous form. In a preferred embodiment the chamber 44 through which the tow 40 is conveyed is basically of rectangular cross-section, the width increasing from entrance to exit and the height decreasing from entrance to exit to provide the divergent forces. The web so formed is dried to remove the liquid conveying medium which may be water or alcohol. A non-woven fabric is made by laminating the web with further so-formed webs, the directions of the filaments lying at an angle to those of adjacent webs, or by laminating the web with one or webs of staple fibres. The layers are united by adhesive applied in a pattern. The filaments may be polyamide, polyester, acrylic, vinylic, cellulosic, polyolefin or polyurethane filaments.
