The guide means 24 may consist of a single block or may be of separate pieces having arcuate cut-out portions to receive the peripheries of the rollers. The cohesive particles may be fed from a hopper 10 through orifice 11 which fits into the top of the guide means 24 and is positioned thereby. The wire may traverse the hopper, through a tubular guide 19 supported by radial arms 20 from the sides of the hopper. A vibrator 27 may be provided to facilitate feeding of the particles. After the coated wire leaves the rollers it may pass through a sintering bath, e.g., a fused nitrite-nitrate salt bath and through burnishing dies. The wire may be heated before coating especially when it consists of a stranded wire. A modified guide means 24a, Fig. 7, may be provided having a conical bore containing a centring die above the contact space of the rollers. The hopper 10 may be fed by a second hopper agitated by an eccentric and receiving cohesive material from a cranked sifter. The hopper may have a spiral screw 38, Fig. 7, extending into the throat and driven by hollow shaft 39 (through which the wire is drawn) and gears 40 and 41. Guide means 24a fitting the crests of the screw and providing a bearing therefor positions the end of the hopper and agitating flails 43 may also be used. The hopper may comprise a plurality of cylinders from which polytetrafluorethylene in the form of ribbons is extruded by a plunger into the roller space. These cylinders may be used in opposed pairs, i.e., in a four cylinder system two may be used and the other two held in readiness for use during re-charging of the first pair.

Title: Improvements in harpoon guns
IPC: F41B11/83
Filed: 1959-05-14
Abstract: 882,433. Harpoon guns. HAYWARD, G. O. May 14, 1959, No. 16640/59. Class 77. In a harpoon gun comprising a barrel 1, Fig. 3, and a casing 11 and fired by compressed air, the air is pumped via a non- return valve 4, the barrel and apertures 13 into a reservoir 12 located between the barrel and casing. Excessive reservoir pressure is prevented by a bleed valve 34 and when the trigger 22 is pulled a rod 24 pivots a sear 17 to release the harpoon 14. A sleeve 19 slidable along the harpoon to hold the sear against movement comprises a safety catch. In a a modified gun a hand pump and a non-return valve assembly replaces the valve 4 and its securing cap 3. In a further gun the harpoon is loaded by a hand operated lever actuated arrangement comprising a lever 40, Figs. 2, 5, side members 42 and a harpoon engaging plate 43. In Fig. 2 the gun is leaded and the loading mechanism is inoperative being clipped to the casing wall. A slot 44 is formed in the plate 43 such that when the lever is oscillated to force the harpoon down the barrel against an air loaded piston 10 the slot edges only grip the harpoon surface on clockwise movements of the lever the subsequent anticlockwise movements causing the edges to slide along the surface. During these sliding movements the harpoon is held by a spring-loaded sear 48, Figs. 11, 10, the lower edge 50 of which is shaped to engage the harpoon shaft. The edge is held in contact with the shaft by pivoted members 58 which through a member 61 and a rod 24 are connected to the trigger 22. The sear, although held, has limited pivotal movement so that the harpoon may move into the barrel during the clockwise movements of the lever 40. On trigger release the members 58, Fig. 10, swing downwardly and the sear, under the action of its springs 56, pivots upwardly, Fig. 10, to release the harpoon. The lever loading system is constructed to allow slot (44) disengaging lateral movement of the plate 43 from the harpoon after loading and re-set of the sear is effected manually through a button 54.

Abstract: 479,184. Testing physical qualities of materials. AKTIEBOLAGET TERMISK ISOLATION. June 16, 1937, No. 16749. Convention date, June 22, 1936. [Class 37] [Also in Group XL] A vacuum insulation, particularly for a refrigerator cabinet, cooling van, &c., is provided with means for testing the degree of low pressure comprising a recess or pocket within the insulation containing an electrical detector element responsive to variations of pressure on the application of voltage thereto, which is in continuous communication with the vacuum space. In the construction shown, an evacuated insulation space 11 is enclosed between walls 12, 13, the outer wall 13 being formed with a recess 14 in which is mounted a discharge tube 15. This consists of a glass cylinder 16 to which is welded a metal cylinder 17 which projects into the space 11 and is welded to the wall 13 to make a vacuum-tight seal. A porous plug 19 prevents entry of fine powder such as kieselguhr, with which the space 11 is filled. The recess may be covered with a sieve-like or other transparent cover plate 26 through an insulator in which passes one electrode 30 of the discharge tube. A second electrode 18 is connected to the metal cylinder 17 and thence to the outer wall 13, which is provided with a terminal 20. To make a test, the terminals 20, 30 are connected to an induction coil or other current source, the degree of vacuum being indicated by the nature of the glow. The metal portion 17 of the tube may be bent so that the whole tube is of U-shape, thereby reducing the length of the recess 14. In a modification the detector element may comprise a hot wire, through which a constant current is passed. The voltage across the wire is measured, thereby determining the resistance, which is dependent on the vacuum. The detector element and the recess walls may be mounted on a separate plate which is welded to the outer insulation wall or to the outer refrigerator cabinet wall.

Abstract: 186,148. Thompson, H. A., and Smith's Dock Co., Ltd. June. 21,1921. Air and steam pressure sprayers.-In an atomizer for liquid fuel separate fluids, such as oil and steam or air, are each discharged into a central outlet chamber fitted with a central discharge orifice from converging and tangentially disposed passages leading from annular supply chambers or an annular and a central coaxial supply chamber, a whirling motion being thus set up within the nozzle. Fig. 1 shows a form comprising a back body part a and a front body part b screwed thereto, formed with registering recesses, which form an annular supply chamber c and an outlet chamber e. The back plate is formed with a hollow conical projection g, forming a central supply chamber h and a directing-cone. One. fluid is supplied from the pipe j to the central chamber and the other by a pipe k to the annular supply chamber c, and from these the fluids pass. through tangential ducts d, i to the central discharge orifice f. In the form shown in Fig. 3, the annular supply chamber c is located around the central chamber h and behind the tangential ducts i, and both sets d, i are inclined forwardly to discharge into the rear end of the outlet chamber e. In the modification shown in Fig. 4, an additional air-supply passage m is provided in the centre of the directing-cone g, which may be closed by a conical plug, Fig. 8, when the additional air supply is not required, the plug being formed with a conical end to fill the apex of the cone g. The supply chamber h is of annular form, and discharges through tangential passages i into the outlet e along the face of the cone g, whilst the annular chamber e discharges through tangential slots formed in an annular partition wall d', which separates the supply chamber c from the outlet chamber e. In another modification, an annular lip is formed around the cone g so as to direct the one and steam forwardly before they meet on the outlet chamber. The spray-producer may be provided with an additional auxiliary air-admission chamber formed as an extension of the front-bodv h and provided with additional air passages in front of the outlet chamber. In this form, the outlet nozzle f may be omitted. Specification 27324/12 is referred to.

Abstract: 403,376. Aerials. LORENZ AKT.- GES., C., 1, Lorenzweg, Tempelhof, Berlin. June 16, 1932, No. 17038. Convention date, Oct. 7, 1931. [Class 40 (v).] - To reduce the spacewave component and to radiate energy that is predominantly earthbound, thereby reducing fading effects in broadcast transmission, one or more dipoles are arranged so that the centre of oscillation of the highest dipole is within half a wavelength of the ground. In Fig. 3 three such dipoles Di...Di<11> are arranged one above the other with the intermediate spacing shown, the oscillation centre of the uppermost being five-twelfths of a wavelength above ground. To ensure a constant effective height, an invariable earthstructure is provided below the aerial system having a diameter of at least half a wavelength. As shown in Fig. 9, the geometrical length of the aerial may be shortened by adding horizontal portions N, N1 at the top and bottom, energization taking place at the lower end of the aerial through a non-radiating feed-line F. Figs. 10 and 11 respectively show methods of suspending a single dipole Di, and one or two pairs of dipoles, placed back to back. Fig. 12 illustrates node coupling, and Fig. 13 loop coupling to the feed lines. Or coupling may be to the lowest dipole. The invention is applicable to circular arrangements of aerials designed to emphasize the ground component of radiation such as are described in Specification 396,740. The size of the dipoles and the amplitude and phase-relation of the currents fed to them may also be varied to ensure a favourable distribution of the horizontal field.

Title: Improvements in and relating to electric motor control systems
IPC: B66B1/08
Filed: 1919-07-08
Abstract: 153,626. British Thomson - Houstor Co., (General Electric Co.). July 8, 1919. Electric braking.-Relates to motor-control sys tems in which the speed of running is automatic ally regulated by a brake-releasing solenoid. The invention consists in the use of a reversing con troller and circuit arrangements to obtain specified braking effects. The Figure shows the invention applied to an alternating-current motor M of the slip-ring type, which is geared to a hoisting-drum H, and is provided with a reversing controller and regulating resistances R, R1, R2. Two brake shoes 12, 13 are normally biassed to press upon a brake drum B by means of a lever 17 weighted with two masses of iron 15, 23. In order to vary the braking effect, the two iron masses are mag netized by coils 10, 11 and are attracted upwards by two fixed armatures 29, 30. When the con troller is turned to the hoisting side, indicated by the segments on the right of the diagram, the coil 11 is connected across two of the mains a, c the first step including a resistance r, and the second step cutting it out. The attraction thus set up between 29 and 15 relieves the brake partly in the first position and completely in the second position. In the first running position the brake is also relieved by the action of the coil 10, which is connected across a portion of the motor controlling resistances and thus act less strongly in proportion to the increase of the speed of running. When the controller is turned to the lowering side, indicated by the left-hand set of segments, the coil 10 acts alone.in the first four positions, regulating the speed as before, and in the last four positions the coil 11 acts and relieves the brake completely.
