Title: Improvements in or relating to breech loading mechanism for ordnance
IPC: F41A9/42
Filed: 1941-08-20
Abstract: 578,742. Ordnance. MOLINS, D. W., and MOLINS MACHINE CO., Ltd. Aug. 20, 1941, No. 10627. [Class 92 (i)] [Also in Group XXXVII] Relates to breech loading ordnance in which a loading tray movable between loading and ramming positions has a ramming carriage movable in guides on the tray by a source of a power remote from the tray. According to the invention, a mechanical coupling between the source of power and the ramming carriage includes a flexible shaft. In the form shown, a loading trav 1 is movable about an axis 2 relatively to the gun breech 3 between a loading position to one side of the breech and a ramming position in line with the gun chamber. The rammer 7 which slides in the tray 1 is propelled by an electric motor on the gun 12 driving a flexible shaft 14 connected to a pinion on the ram which engages a rack fast with the tray. The rammer is returned whilst the tray is in the loading position. Fig. 5 shows the electric circuits controlling the motor. The motor with fields SF, ShF and armature A as shown is of the compound-wound type and the circuits are reversed by a throw-over switch T.O operated by the swinging of the tray 1. The handle 23 for locking the tray in its two operative positions actuates a switch TRS to energize through a relay SFR a contactor C for starting the motor. The motor is connected through reduction gear to a cam 24 so that, after a given number of revolutions for the ramming and return movements, limit switches RmL RtL are operated by the cam and the motor is brought to rest by buffers and by short-circuit or dynamic braking. Specification 276,389, [Class 92 (i)], is referred to.

Title: Improvements in or relating to electroplating
IPC: C25D17/10
Filed: 1964-03-13
Abstract: In electroplating, etching is prevented in the non-plating low current density areas of the cathode by placing an electrically conductive baffle in direct physical and intimate electrical contact with the cathode between the plating and non-plating areas.  The baffle may be of a shape geometrically complementary to the low current density areas of the cathode and direct electrical contact may be augmented by conductors clamped to both baffle and cathode. As described the process is applied to electroplating the inside or outside of cylinders with chromium from a chromic acid bath containing sulphate and silico-fluoride ions, but is applicable to plating with metal any metal article especially iron alloys such as cast or wrought iron, or carbon, nickel or stainless steels in highly polished condition. The baffle may be of carbon or of any metal, e.g. iron, steel, nickel or it may be of the same metal as the cathode or have an etch-resistant surface as of Watts nickel, silicon containing iron, or metals of hydrogen overvoltage less than 0.33 volts at a current density of 0.1 amps/dm2 (see The Corrosion Handbook by H. Uhlig, John Wiley 1948) as in Specification 1,064,295.

Title: Improvements in or relating to directive aerials
IPC: H01Q1/14
Filed: 1926-04-28
Abstract: 251,638. Levy, L. April 28, 1925, [Convention date]. Addition to 233,346. Aerials; oscillation generators; directive signalling. - Aerials comprising two systems of intermeshing wires arranged in a plane and connected to one another through a centrally arranged oscillation generator, as described in the parent Specification, are modified according to the present invention by arranging the wires so that they are inclined to one another, the mesh arrangement being abandoned. The wires are situated at a height greater than a quarter wave length. Currents of like frequency but different phase, or of unlike frequencies, are employed, so as to produce a circularly polarized radiation, or radiation with a rotating plane of polarization. Thus two groups of wires lying in the same horizontal plane may be mutually inclined. The parent invention may also be modified as shown in Fig. 2; or, as shown in Fig. 3, four aerial arms 1, 2, 34, 35 may be supplied by thermionic or other generators so that the current in each arm differs in phase by 90‹ from the currents in adjacent arms; in this way a horizontal electric field rotating at the oscillation frequency is produced, the radiation being circularly polarized for the vertical direction of propagation. With a phase angle different from 90‹ elliptical polarization is obtained. If however the frequencies of the currents supplied to opposite pairs of arms be different, the rate radiation with a rotating plane of polarization is obtained. The Specification as open to inspection under Sect. 91 (3) (a) also contains the following subject-matter: (i) current may be similarly supplied to a vertical and a horizontal aerial in combination it is stated that a beam having a helical motion can be produced, and utilized for enabling vessels to determine whether they are approaching or receding from one another. (ii) It is stated that the use of horizontal and vertical aerials in combination will enable vessels to ascertain their courses by comparing the directions of the magnetic and electrostatic sectors of the radiation reaching them. (iii) Two rigid aerial tubes 1, 2, Fig. 7 (Cancelled), may be mounted on a stand 3 by a universal joint and set so as to radiate in any desired plane. (iv) Light polarized at 45‹ to the vertical may be used in vehicle lamps to prevent dazzle, the driver wearing analyzing goggles which protect him from approaching headlights. This subjectmatter does not appear in the Specification as accepted.

Patent GB-893642-A (GB)
Title: Process and apparatus for preventing losses from storage vessels for volatile liquids
IPC: B65D90/30
Filed: 1960-03-30
Abstract: <PICT:0893642/III/1> In a plant for preventing losses from storage vessels for volatile liquids, a storage vessel 10 containing a volatile liquid, e.g. a petroleum fraction, is connected to a liquid-ring pump 20 by a pipe 13 connected to the vapour, space of the vessel 10 and by a pipe 24 connected to the liquid space of the vessel.  The pump 20, the construction of which is described in Specification 813,420, is driven by a motor 18 which is automatically operated by a pressure-sensitive switch 14 when the pressure in the vessel 10 rises to a predetermined value and is cut off by a pressure-sensitive switch 16 when the pressure in the vessel 10 is sufficiently low.  The solenoid valve 22 permits liquid to flow from the vessel 10 to the pump 20 only when the motor 18 is in operation. The effect of the arrangement is that vapour withdrawn through the pipe 13 is compressed in the pump 20 and reabsorbed, at least in part, in the liquid fed to the pump through the pipe 24, the liquid containing reabsorbed vapour passing from the outlet 28 of the pump to the vessel 10 through a pipe 32 having a non-return valve 30. Unabsorbed vapour from the pump 20 passes through a pipe 36 to a storage tank 40 for use in repressurizing the vessel 10 when required.  For this purpose the tank 40 communicates with the vessel 10 through a pipe 48 carrying a valve 52 which is responsive to the pressure in the vessel 10, to which it is connected by a pipe 56. Vapour may be discharged from the tank 40, if necessary, through a pipe 50, or additional gas for pressurizing the vessel 10 may be supplied through a pipe 58.

Abstract: 666,648. Electric indicating systems. LANDIS & GYR SOC. ANON. April 29, 1949. [May 18, 1948] No. 11512/49. Class 40 (i). [Also in Group XIX] In a viscosimeter having a rotatable shaft 7 with measuring vanes 36 at one end, the other end of the shaft is coupled through a cam 22 to the inner end of a spirally wound measuring spring 19, the outer end of which is rotated at constant speed by a stationary motor 17. The variations in the stressing of the measuring spring 19 cause movement of the cam 22 relatively to a bell-crank lever 23 and such relative movement is transmitted by the bellcrank lever 23 to stationarily arranged indicating or evaluating devices such as an indicator 27 and an electrical transmitter 29. Where a desired relative proportion of e.g. two,'ingredients is of a definite viscosity, such a relative proportion may be obtained by using the electrical transmitter to control the addition of the ingredients to the mixture under test. The outer end of the spring 19 is connected to a casing 18 rotated by the motor 17, and the bellcrank lever 23 is secured to and rotates with this casing. The relative displacement between the cam 22 and the spring casing 18 is limited by two extensions 32 and 33 on the cam 22, Fig. 2, being spaced apart about an extension 34 on the spring casing 18. A releasable ball or friction coupling 21 is included between the shaft 7 and the cam 22. The vanes 36 are of unequal sizes to set up vibrations for overcoming friction between the moving parts.
