Title: Apparatus for determining ranges & data for use in directing fire
IPC: B65H23/04
Filed: 1917-06-18
Abstract: 138,942. Hammond, J. H., and Buswell, H. L. F. June 20, 1916, [Convention date]. Multiple-indication apparatus.-A range-finder of the long-home-base type, and for use on aerial targets &c., comprises two or more aiming elements for sighting the target, and three cooperating indicating elements, of which two are oscillated by and in accordance with the oscillations of two of the aiming elements about parallel axes, and the third is operated by and in accordance with the oscillations of one of the aiming elements in altitude. The parallel axes may be vertical, so that the first two indicating elements show the horizontal range &c., or these axes may be revoluble so as to be always normal to the plane of sight containing the base, the first two indicating elements then showing the range &c. in this plane. The third indicating element may directly co-operate with one of the other indicating elements to show the height of the target, the tangent elevation, the time of flight of the projectile, &c. In this apparatus the two indicators may be replaced by one indicator constructed as shown in plan in Fig. 11. In this form, the indicator comprises a fixed graduated bar 322 corresponding to an arm of the primary indicator, a rotary cone 325 corresponding to the secondary indicating apparatus, a plate 302 revoluble about an axis 304 by an electric repeater and corresponding to the base of the range-finder, and an arm 312 mounted on a spindle 311 rotated by a repeating mechanism 310 which is adjustable along the plate 302 in accordance with the length of the base. The arm 312 corresponds with a second arm of the primary indicator and indicates ranges on the bar 322. The axis of the cone 325 intersects the bar 322 on the axis 304, and the cone is rotated about its axis by a repeating mechanism operated by the transmitter in the easing. The surface of the cone carries a line chart showing horizontal ranges and altitudes, or the tangent elevation and fuse times, or any or all of these quantities, and their value is read at the intersection of the bar 322 and arm 312. Alternatively, a combined indicator similar to that shown in Fig. 11, but with a cylinder in place of the cone, may be used.

Abstract: 558,065. Sponge rubber. UNITED STATES RUBBER CO. June 26, 1942, No. 8770. Convention date, July 2, 1941. [Class 70] A foamed aqueous rubber dispersion containing zinc oxide and ammonium- or an alkali metal silicofluoride is stabilized by adding ammonium- or an alkali metal hydroxide and a substance which precipitates zinc ions, whilst retaining the structure of the foamed dispersion; these substances, if added when part of the apparatus dealing with the dispersion breaks down, prevent the foam from coagulating therein and being wasted, the foam being later re-sensitized by more silicofluoride. The zinc ion precipitant may be alkali metal or ammonium tetraborates, carbonates or metaphosphates, or other water-softening chemicals. If sodium or ammonium silicofluoride is used as sensitizer a potassium salt, e.g. the chloride, sulphate,-or nitrate may also be added to aid in preventing coagulation, or alternatively the hydroxide may be of potassium, or the zinc ion precipitant may be a potassium salt, or any combination of these ways of introducing potassium ions may be used.

Abstract: 1306256 Shift in calculators MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 26 Feb 1970 [26 Feb 1969 (2)] 9353/70 Heading G4A Shifting apparatus includes shift register means forming part of a circulating loop containing a plurality of registers, and includes means to shift one of these registers ahead by one register position, and to shift one to another in a digit position lower by one digit. General.-An electronic calculator includes a recirculating loop consisting of a 152.bit shift register (or delay line) and two 4-bit shift registers, all in series, and holding four recirculating registers each of 10 binary-coded decimal digits. The 10-digit registers are interleaved at digit level. Multiplication.-Initially the first, second and third 10-digit registers hold zero, multiplicand and multiplier respectively. The second register is left-shifted with incrementing of a counter until a non-zero multiplicand digit is in the highest-order position. Then, by by-passing the two 4-bit shift registers, the third register is transferred into the first and the first, with a onedigit shift to the right (low-order), into the third, so that the first now holds the multiplier and the third is empty. The second register is added into the third with decrementing of the lowest-order digit in the first until the latter digit reaches zero when, unless the counter is zero (end of operation) the counter is decremented and the interchange of first and third registers described above is performed again twice, effectively right-shifting both by one digit position. Then the next multiplier digit is dealt with as above, and so on.

Filed: 1969-02-21
Abstract: 1,246,700. Ultrasonic holography. HOLOTRON CORP. 21 Feb., 1969 [6 March, 1968], No. 9395/69. Heading H4D. [Also in Division G2] An ultrasonic hologram is formed by directing a first ultrasonic beam from a transducer towards a hologram detecting surface, and directing a second ultrasonic beam through a test object and then through the transducer to interfere with the first beam at the detecting surface. This allows short path lengths for the beams (hence low attenuation) and a small angle between the beams (without the object blocking the first beam) so that a high quality hologram can be formed using high ultrasonic frequencies, e.g. greater than 20 MHz. As shown the first beam is generated by quartz plate transducer 61 and is incident at angle # r  on detecting surface 63 which comprises a thin liquid film 79 (e.g. of water, mineral oil, silicone oil or a fluorocarbon) supported on an acoustically transparent sheet of metal or plastics (e.g. polyethylene, polyethylene terephthalate, polyvinyl chloride) in a frame 77. The second beam is generated by quartz transducer 65 supported in liquid-filled tank 71 and passes through test object 67 and through transducer 61, the transducer thicknesses being odd multiples of a half-wavelength at the operating ultrasonic frequency so that transducer 61 is acoustically transparent. Frame 77 isolates surface 63 from disturbing vibrations of the body of liquid 73. An optical image is reconstructed by diffracting light (from a high pressure mercury lamp 39) from the hologram, using the optical system shown which includes a spatial filter 53 to block all but a first order diffraction beam. "Noise" in the optical image as a result of disturbing vibrations of tank 77 walls may be removed by filter 53 if this noise is displaced from the said first order diffraction beam, e.g. by making tank 77 rectangular. Alternative forms of hologram detecting surface are discussed.

Abstract: 315,392. Schieferstein, G. H. July 14, 1928, [Convention date]. Vibrations, indicating and recording, - An accelerometer is provided with an arrangement which eliminates the indicating or recording of constant accelerations, e.g. gavity, and only indicates or records changes in acceleration. An accelerometer based on the microphone principle has a mass a covered on both sides by carbon plates b<1> and b<2> and suspended on a flexible medium m which keeps the mass a fixed with regard to two spatial axes whilst allowing a certain freedom of movement along a third spatial axis, i.e. the axis of the casing g. At the central points of the baseplate and cover i are arranged screws k<1> and k<2> which can cause the diaphragm, membranes or other flexible members h<1>, h<2>, to each of which is fixed a carbon contact c<1>, c<2>, to approach or recede from the carbon plates b', b<2>. Fig. 3 shows the apparatus set up for use in one arrangement, in which T is a transformer which takes up and transmits each fluctuation in the current to the instrument o, whereas it does not react to direct current due to a constant pressure at the carbon contacts caused by a constant acceleration. The exclusion of the indicating or recording of constant accelerations can also be effected by interposing two condensers c', c<2>, Fig. 4, by means of which a flow of direct current is interrupted. The indicating or recording of constant accelerations can also be eliminated by the finding of new mechanical or electrical zero points, in the apparatus shown in Fig. 1, by adjusting the contacts c', c<2> until the currents in the circuits of both contacts be equal, to aid which an arrangement is described in which rotation of the casing g adjusts one of the contacts, and in the arrangement shown in Fig. 4, without the condensers, by displacing the conductor v on the coil s until a new electrical zero point is found. The apparatus can be calibrated by applying known forces in the carbon contacts.

[Also in Group XIII] In regulating means for a fuel-irijection engine the fuel-air ratio is regulated with the aid of a single thermostat 36 which responds directly or indirectly to the temperature of a coolant or lubricant flowing through or in contact with the engine as well as to the temperature of the combustion air. A pump 1 delivers water into the cylinder cooling jacket from whence it flows through a space 37 and returns to the pump either via a pipe 8 or a radiator 6 depending upon the position of a thermostatically-controlled valve 4. A fuelinjection pump 9 has its regulating rod 11 connected by a lever 20 to both a governor diaphragm 19, and, through another link 25, to the valve 4; the diaphragm chamber 18 is connected to the induction manifold 15 adjacent the throttle valve 14. The thermostat 36, which projects through the space 37 into the air admission passage 39, is connected by a link 40 to the lever 20; the thermal element in the valve 4 may be dispensed with. In an air-cooled engine the thermostat is placed in the path of the air downstream of the engine. In a modification, the thermostat is arranged to act upon a second throttle valve, not shown, instead of the injection pump the latter being regulated by the suction in the induction manifold as described above. The thermostat may be acted upon by the air used to cool the cooling water, the engine lubricant or the air used to cool the latter ; the thermostat may be arranged in contact with the walls through which the medium is flowing instead of, or in addition to, the temperature of the medium itself.
