Title: Improvements in or relating to means for changing a gun carriage from a limbered-up travelling position into a firing position on a platform
IPC: F41A23/28
Filed: 1938-07-28
Abstract: 503,387. Field-gun carriages. RHEINMETALL-BORSIG AKT.-GE8., and SONNEN. SCHEIN, W. July 28, 1938, No. 22459. [Class 92 (i)] A field carriage is moved from the limbered-up travelling position, Fig. 1, into a firing position on a platform d, normally slung beneath the trail, by means of a winch g on the carriage which, after being used on a hook d<3> to lower the platform to the ground, is connected round a pulley such as a<4> so as to raise the carriage on a pivotal support e to the position shown in Fig. 3. Further, the cable is then used round a pulley d<4> and over a hook h', as shown in Fig. 4, to free the trail from the limber b. The lowering of the platform to the ground causes a nose e<1> on the support e to engage in a recess in the crank arm a<3> of the spring suspension which is then still under load when the carriage is lifted off the ground. The support e is locked in raised position by a bolt d<2>. The winch can be, further used to move the gun barrel rearwardly on the trail for transport or to transfer the gun barrel to a separate transport vehicle.

Abstract: 1315544 Making orifice structures, extruding BRUNSWICK CORP 12 May 1970 [12 May 1969] 23013/70 Headings B3A and B3P [Also in Divisions B5 and C1] A method of making an orifice structure comprises assembling at least two bodies into a billet, the assembled bodies defining a bore through the billet, providing a sacrificial element within the bore, constricting the billet into a homogeneous structure and removing the sacrificial element. A rod 14, e.g. of stainless steel, is provided with a slot, in which a machined insert 20 fits snugly. A Monel 400 (Registered Trade Mark) rod 28 is placed in a slot 26 in the insert, which is then secured in the slot in the rod 14 by welding. A nose cone (36), Fig. 6 (notshown), is welded to one end of the rod and an end cap (32) with an evacuation tube (34) welded to the other. The billet so formed is evacuated at a temperature of 750-800 F. and then sealed. The evacuated billet is then heated to 2100 F. and extruded in a series of passes, the nose cone and end cap being cropped off after the first pass. The extruded rod has a diameter of 0À128 inch and is sliced into pieces 0À053 inch thick. The Monel rod is leached out to provide an orifice of approximately 19 microns effective diameter. In alternative embodiments, the billet comprises a number of abutting portions surrounding the sacrificial element, or a plurality of concentric tubes surrounding the element, Figs. 11, 13, 14 (not shown). Plastics material, glass, or the like may be used instead of metal.

Abstract: 848,602. Cathode ray oscillographs. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. June 2, 1959 [July 17, 1958], No. 23028/58. Class 37 In a picture tube sound monitoring arrangement for a television system with accompanying sound, comprising means for producing pulses of sound dependent signals at a pulse repetition rate equal to the television line frequency, each of which occurs at or near the commencement of each scanning line; means are provided for combining the pulses with a saw tooth waveform of and synchronised with the television field frequency and for applying signals thus obtained to a television tube whereby a line extending in the framing direction and of a length dependent on the sound signal strength is displayed marginally of the picture area. Sound signals at terminals 1 after rectification and integration in unit 3 are gated by pulses of line frequency, derived from the line fly back pulses, and applied to terminal 5, into a combining circuit 6 fed with a frame-frequency, saw-tooth wave form at terminal 7. The output from a common cathode resistor 63 is applied to the picture tube through a limiter 8. The nature of the outputs from units 4 and 6 and the result of the latter are the picture screen for two different signals are described with reference to Figs. 2-7 (not shown). The line length, sound signal strength may be linear or logarithmic. In a further embodiment Fig. 8 the sound signal is applied to gating circuit V4, V5 through a peak rectifying circuit VI, V2 and an amplifier V3 and positive going spikes obtained from the output of line frequency valve V8 by differentiation and amplification in valve V9 are applied to the grid of V4. A saw tooth wave-form developed across a resistor FR in circuit with the deflection coils FS serves to gate the pour at frame frequency to produce a number of spikes which is a function of the audio amplitude and apply them via a monostable multi vibrator V6, V7, a blocking oscillator VII to the video input circuit of monitoring tube MT.

Title: Improvements in and relating to gyro compasses
IPC: G01C19/38
Filed: 1929-07-27
Abstract: 405,034. Gyroscopic compasses. BREWERTON, A. E., 39, Higher Drive, Purley, Surrey. July 27, 1929, No. 23101. [Class 97 (iii).] A gyroscopic compass comprises an orienting wheel and driving motor supported upon a member which conveys the necessary torque to the wheel and allows angular freedom of the wheel and the motor mutually about axes other than the axis of rotation. As shown the gyrowheel 1 is mounted on the shaft 2 of an electric motor 3, this shaft having a spherical portion 4 running in a spherical bearing 5 in the support 6. Weights 7 carried by the casing of the motor provide gravitational control for the compass and also prevent rotation of the casing. A damping couple is derived from the power delivered to the motor. When the rotor speed is constant the applied electrical torque is equal to the sum of the resisting torques duo to friction and windage in all the rotary parts and is therefore greater than those in the motor itself. The motor is therefore subjected to a torque about the axis of spin and the weights 7 are displaced about this axis. The weight displacement produces a torque about the horizontal axis lying in the vertical plane containing the spin axis so that if the spin axis is not horizontal there is a resultant torque in the plane containing the spin axis and at right angles to the vertical plane containing this axis, this torque being in the required direction to reduce the tilt of the spin axis. To prevent the damping factor from varying according to the torque given by the motor the weights 7 may be caused to be inclined from the vertical by a definite amount by means of a cardan ring 10 pivoted about the axial and horizontal centres of the members 4, 5 and carrying a pin 11 engaging in a member 12 fixed to the gyroscope system. The support 6 is mounted on a turntable 15 which is made to follow the azimuth movements of the axis 2 by maintaining members 13, 14 in alignment. The table 15 is provided with a graduated ring adjacent a stationary pointer 16. When used on a ship the table 15 may be stabilised by means of a long period gyroscopic pendulum. To minimise disturbances due to change of course and/or speed, means may be provided whereby when such change exceeds a certain amount the ring 10 is moved axially so that the pin maintains the control weights 7 in a central position and the compass becomes undamped. Specification 206,541, [Class 97 (iii), Thermometers &c.], is referred to.

In a cathode-ray tube in which the screen consists of grains of luminescent material enveloped in a substance which protects them from positive and negative ions, the potential of the screen is stabilised by bombardment with additional electrons which may be derived from a flooding or scanning beam. These electrons have a velocity sufficient to generate secondary electrons at the screen but not exceeding two thirds of the mean velocity of the main beam, while the substance enveloping the grains is sufficiently thick to prevent penetration of the additional electrons. The enveloping substance may be alumina, magnesia, silicon dioxide or mixtures thereof.
