Title: Method of discharging static electricity from bodies
IPC: B64D45/02
Filed: 1939-02-15
Abstract: 524,912. Discharging electricity from aircraft. BENDIX AVIATION CORPORATION. Feb. 15, 1939, No. 5022. Convention date, Feb. 23, 1938. [Class 4] [Also in Group XXXV] Electrostatic charges are discharged from bodies in motion, such as aircraft, by conducting the charges to a point from which they are discharged into the surrounding air through a path of high electrical resistance. In one form a conductor 13, Fig. 3, preferably of small diameter, is connected to the aircraft through an insulated conductor 12, discharge therefore taking place from the wire 13 only. High resistances in the ferrules 11 and 14 prevent surging of current. In another form, liquid or powder is discharged from the nozzles 32, 33, 34, 35, 41 and 42, Fig. 4. An air pump 24 connected with nozzles surrounding those mentioned above causes liquid or powder to be drawn from the reservoir 43 and discharged in a finely divided condition, carrying away electric charges from adjacent parts of the aircraft.

Title: Wrapping machine
IPC: B65B11/42
Filed: 1959-02-13
Abstract: 856,905. Wrapping machines. HESSER MASCHINENFABRIK A.G., F. Feb. 13, 1959 [Feb. 26, 1958], No. 5071/59. Class 94(1). A machine for wrapping up articles and seaming the edges of the wrapper together, comprises two mandrels 11 of a cross sectional shape corresponding to that of the article to be wrapped, the article being held between the mandrels during a part of the wrapping operation so that the wrapper is folded not only around the article but also around the mandrels to ensure a parallel alignment of the opposed longitudinal edges of the wrapper. The mandrels are withdrawn before the ends of the package are closed and sealed. An endless conveyer 1 moves the articles G into the machine against a stop. A reciprocating carriage 4 carries a pivoted slide 3 that pushes the articles G, two at a time, into a trunking 27 to a position in front of a wrapping sheet E. A pair of mandrels 11 are coupled by pivoted arms 10 to the carriage 4 such that at the end of each return stroke of the carriage 4 the mandrels 11 will be aligned with the articles G in front of the wrapping sheet E. As the carriage 4 performs its next forward stroke the mandrels 11 close on the articles G, and pivoted elements 28, also on the arms 10, move into engagement with the rear faces of the articles to push them against the wrapping sheet E and through a folding enclosure 34 to fold the sheet E into U-shape about the articles G and the mandrels 11. The partially wrapped articles are received by gripping jaws 35 of an intermittentlyrotatable conveyer 36 and, in this position, electrically heated jaws 37, 38 act to unite the transversely extending edges of the sheet together. The mandrels 11 then move out of the wrapper and the conveyor 36 moves the partially wrapped packages past fixed arcuate folding plate 45 to fold down the seam formed by the jaws 37, 38. The package is then brought to a further station (not shown) which, in known fashion, first spreads the two ends of the wrapper and then heat seals them at their inner marginal zones. Adjustments. To enable the spacing between the mandrels 11 to be adjusted the pivot of the arm 10 on the carriage 4 may be displaceable. Instead of two articles G, a single article may be wrapped.

Title: Improvements relating to head lamps for vehicles
IPC: H01K9/08
Filed: 1924-02-28
Abstract: 228,366. Lilienfeld, J. E. Feb. 28, 1924. Bulbs; reflectors and screens within bulbs; filaments; multiple-filament lamps; holders. - A vehicle head-lamp is constituted by a lens-shaped incandescent lamp bulb 3, Fig. 1, having an internally-silvered parabolic back portion 1, with or without a protective covering 2, a filament 5 partly behind and mostly in front of the focus F and a conical internal reflector 4 which is supported by one of the leading-in wires and directs light on to the main reflector 1. The filament 5 may be conical, as shown in Fig. 5, or cylindrical, and for town driving a second filament 6 may be mounted above the reflector, as shown in Fig. 8, substantially horizontal in a plane normal to the axis of the parabolic reflector. The reflector 4 cuts off some rays of the filament 6 from the lower part of the reflector 1 in order to reduce dazzle, and this action may be assisted by a screen or rim 7 on the reflector. Direct emergence of rays from the filament may be prevented by means of metal blades on the screen 7, by a pane of frosted silica or glass, or by frosting or silvering a circular area A-B on the front of the bulb, in which case the front of the bulb is preferably made concave, as shown in dotted lines. The two filaments 5, 6 may be illuminated separately or in series or'parallel. The covering 2 may be of a plastic rubber compound or of plaster or the like covered with sprayed aluminium or other metal, or, alternatively, it may be replaced by an all-metal hood. The lamp is secured to the holder 13 of the vehicle by a clamp 12 which serves also to prevent the bayonet joint from working loose.

Title: Improvements in or connected with musical drums
Inventor: DAVIS LEWIS
IPC: G10D13/02
Filed: 1958-02-18
Abstract: 913,631. Musical drums. SELCOL PRODUCTS Ltd. Feb. 18, 1959 [Feb. 18, 1958], No. 5196/58. Class 88 (2). The side walls of a drum are constructed by injection moulding in a plastics material to form two cylinders 1 and 2 with inturned and acutely-angled flanges 3 and 4 at one end and with correspondingly positioned notches such as 5 and 6 at their unflanged ends so that when the unflanged ends are butted and secured together mounting members may be secured in the resulting apertures. In the rectangular apertures formed with notches 5 and 6 a plug 12 may be secured to provide a mounting for a casting 8 which has slots for the accommodation of nuts 15 and tensioning screws 11. Alternatively, a threaded sleeve may be embedded in the plug 12 and engaged by the tensioning screws from both ends. The plug 12 may be integral with the casting 8 and be secured to the side wall by clamping it between the halves 1 and 2 when these are joined together; this method also being used to mount members of a snare mechanism in apertures 7 on opposite sides of the drum wall. One member of the snare mechanism is fixed while the other has a cam-riding tension lever (see Figs. 1 to 5, not shown). The drum skin, which is of synthetic material, is tucked into the angle of a flanged hoop 24 by a metal ring 26.

Title: Improvements in means for protecting airscrew blades and the like
IPC: B64C11/20
Filed: 1941-04-22
Abstract: 546,768. Wire fabrics. YOUNG, P. C. April 22, 1941, No. 5197. [Class 45] [Also in Group XXXIII] In articles such as the blades of propellers or fans, or aeroplane wings having a protective coating consisting of wire gauze or fabric embedded in moisture-proof material, and a metal sheath on the leading edge, the gauze is so formed or manufactured as to provide a channel or recess for the sheath and thereby enable the sheath to lie flush with the cover without rebating the article. The airscrew blade A, Fig. 1, has a cover B consisting of wire gauze embedded in material such as a cellulosic plastic or a synthetic resin, and a leading-edge sheath 2, the longitudinal wires 3 of the gauze being omitted from the part of the cover that underlies the sheath so as to enable the sheath to lie flush with the cover. The part of the gauze that underlies the sheath is filled with a plastic, or a rubbercomposition, solder, or sprayed metal. The transverse wires 4 are so graded in size that the two wires nearest the sheath are flush therewith. As an alternative to omitting wires, the part of the gauze that underlies the sheath may be woven from wires of reduced thickness. The sheath may be unitary or sectional, and may be secured by screws or rivets 5. The sheath may consist of an inner and an outer part united by soldering. The sheath 8, Fig. 9, is soldered to longitudinal understrips 10, and the longitudinal wires 3 of the cover B are omitted at the parts registering with the understrips. Cross under-strips may also be employed, the transverse wires of the gauze being omitted at the parts registering therewith. Alternatively, the wires are not omitted, but are left loose at the parts mentioned and are subsequently cut away, To facilitate application of the gauze, the longitudinal wire that should overlie the leading edge is distinguished by colour or material. To reinforce the gauze, the omitted wires may, except in the region of the under-strips, be replaced by one or more strips consisting of paper, textile material, synethtic fibre, or plaited wire. Preferably, the strips are incorporated in the gauze during manufacture, and are withdrawn from the region of the under-strips. Alternatively, the strips are made from fusible or soluble material, and the redundant parts are removed by a blow-lamp or chemicals. In another alternative, each omitted wire is replaced by a wire or thread of cotton, artificial silk, or gut. When the leading- edge sheath is of increasing width towards the hub, gauze having converging longitudinal wires is employed. Such gauze may be produced by gripping a sheet of ordinary gauze along the zones for the under-strips, stretching the band between the zones, and then cutting away the redundant wires.

Title: Machine for the manufacture of steel wool
IPC: B23P17/06
Filed: 1925-02-25
Abstract: 241,510. Williams Co., (Assignees of Robbins, W. H.). Oct. 14, 1924, [Convention date]. Producing shavings; tools. - Steel wool is made by passing a series of parallel wires past a planing-cutter, the wires being so guided as to pass successively past the same cutter, the same amount of metal being removed at each stage. The wire is coiled on one of the drums 31, Fig. 2, and passes thence to and fro around the guide sheaves 60 in a series of parallel loops, the wire being finally led to the other drum 31. The drums are mounted on stationary shafts 4 and are driven through spur gearing by a variablespeed motor 14 mounted in a cradle 9 which may be swung either way by a hand lever 10 so as to bring the appropriate drum into gear. The wire is thus wound alternately from one drum to the other. The drums are each provided with an internal epicyclic gear which gives a slow rotation to a sleeve having a helical groove engaging a fixed roller, the sleeves and drums thereby being slowly reciprocated acong the shaft 4 to maintain the wire loops in vertical planes. The wires are guided in a table 58, Fig. 2, by rollers 80, Fig. 19, coacting with grooved members 70 mounted in blocks 68 which may rock in the frame 66 so as to maintain the lower surface of the wires in a horizontal plane. The rollers are mounted eccentrically with respect to spindles clamped in eccentric sleeves 83. the sleeves being adjusted independently by handles on collars 97, and the spindle being simultaneously adjusted by a linkage 88 .. 91, Fig. 2, the links 91 having spring yielding elements 87 to prevent strain. The cutters 128, Fig. 9, are mounted in pairs in holders 123 and each comprises a series of cutting edges operating simultaneously on all the wires on the guide 68, Fig. 10. The tool-holders are clamped in the ends of spindles 98 mounted in eccentric sleeves which may be adjusted by links 108 linked by a bar 110, Fig. 2, to an adjustable link 111. The spindles 98 may be. simultaneously rocked through an angle determined by. stops 117, to bring the appropriate cutters into action according to the direction in which the wire is travelling, by links 102, bar 103 and a hand-lever 105. The sleeves 60 are driven by a constant-speed motor 65 at such a speed that the variablespeed motor 14 can maintain a slight tension on the wire and can vary its speed as the wire accumulates on the drums 31, without seriously affecting the tension. The drum 31 from which the wire is being unwound runs against the constant resistance of an adjustable brake. The cradle-swinging handle 10. has attached mecha. nism coacting with notched links 53 so that the cradle may be automatically locked in a central position or in gear either with the right-hand or left-hand drum.

IPC: D06B5/00
Filed: 1963-02-08
Abstract: 1,026,616. Treating textiles. GEBR. POENSGEN G.m.b.H. Feb. 8, 1963, No. 5286/63. Heading D1L. [Also in Division A5] Textile and like material (e.g. hospital bed linen) is placed in a chamber 8 and superheated low pressure steam i.e. between 0 and 0.1 atmospheres is circulated through the chamber to disinfect the material. In the form shown steam is introduced, via a conduit 1, two dryers or de-watering cyclones 3, 5 a conduit 6 and entries 15 into the lower part of the treating chamber 8 in which the material 9, 10 is packed. The steam leaves the chamber from the top via an aperture 12 and conduit 13 to be blown by a fan 14 into an electric heater 16 to be superheated whereupon it passes again to the dryer 5 before being re-cycled through the material. Controlled quantities of the disinfectants e.g. formaldehyde may be introduced into the cycle at 22 and 23. Condensate is continuously removed from the dryer 5 via a conduit 20. The heater 16 is regulated by a thermostat 21. When the disinfecting process is finished a valve 26 is operated so that fan 14 draws in air to be heated and passed through the material, steam and disinfectant being dispelled to the atmosphere via a conduit 27. When drying of the material is completed the heater 16 is switched off so that colder air is blown through the material which is thus brought back to room temperature for unloading. The chamber 8 may be mobile e.g. mounted on wheels and detachable from the conduits 6 and 13 so that it may be loaded remote from the assembly 30, brought to it for treatment and then taken away.

Filed: 1939-02-17
Abstract: 525,333. Bomb fuzes. HUBERT ES SIGMUND ACELES FEMARUGYAR RESZVENYTARSASAG. Feb. 17, 1939, No. 5291. Convention date, July 13, 1938. [Class 9 (i)] The ignition current in an electric percussion fuze is induced by the creation or closing of an air-gap between the separable parts of the softiron armature of a ring-shaped magnet. In one form, the magnet 2 has soft-iron pole-pieces 3, 4, and a two-part armature 7, 8, the part 7 having a spigot portion 11 on which is carried the induction coil 13 of the firing circuit 21. The two parts 7, 8 are normally held in contact by elastic supporting elements 15, 16, and have conical surfaces 9, 10 seated upon conical seats 5, 6, respectively, in the non-magnetic casing 1 of the fuze. On impact, in any position of the fuze, the armature parts 7, 8 are caused' to separate and open an air gap in the path of the magnetic lines of force, thus inducing the firing . current in the circuit 21. In a modification, the two parts of an armature are held apart against the action of a spring by detents which are removed by the action of a clockwork device that is started by the impact and releases the armature, so as to close the air-gap, after a predetermined time lag.

Abstract: 915,290. Transistor amplifying circuits. PYE Ltd. Feb. 3, 1960 [Feb. 16, 1959], No. 5295/59. Class 40 (6). [Also in Group XXXVI] The current through a transistor V 1  is stabilized against temperature variations by means of a thermistor R 2  having a negative temperature coefficient connected to control the bias of transistor V 1  and in thermal contact with it, so that a rise in temperature alters the value of the resistor R 2  and thus adjusts the bias. By directly connecting the base of transistor V 2  to the emitter of V 1  the current through the power transistor V 2  is also stabilized. A potentiometer comprising resistor R 1  and thermistor R 2  is connected across the supply and provides the bias to transistor V 1 , so that on an increase of ambient or junction temperatures the resistance of R 2  decreases, the alteration of the bias due to the change in R 2  reducing the increase in emitter current. The thermistor may be mounted in direct contact with a metal clamp, Fig. 2 (not shown), holding the transistor in position on a heat-insulating base in order to provide good thermal contact.
