Abstract: 676,365. Scoop arm load handling machines. WEATHERILL, F. July 26, 1950. [April 26, 1949] No. 11040/49. Class 78 (iii). [Also in Group XXI] In a mechanical shovel or excavator, side frames 12 are secured to either side of the chassis of a self propelled vehicle and to the upper ends of the vertical limbs of the frame are pivoted a pair of side arms 13 between the outer ends of which is pivotally mounted a scoop 14. The arms 13 are rotated by hydraulic jacks the rams 15 being connected by universal couplings 36 to brackets 17 formed on the side arms 13 whilst the cylinders 32 are mounted intermediate the ends thereof on the frame 12 in universal mountings 16 which are situated below and to the rear of the pivotal axis of the arms 13. The angle of the scoop is adjusted by a double-acting hydraulic ram 19 and link rods 20, 21. To prevent the scoop rotating whilst in the digging position it is locked in said position by a cam-controlled tongue engaging a slot in the scoop. The front wheels are arranged to track in a less width than the width of the scoop.

Title: Improvements in or relating to the preparation of titanium dioxide
Inventor: HUGHES WILLIAM
IPC: C01G23/07
Filed: 1955-04-22
Abstract: In the production of rutile titanium dioxide pigment by reacting titanium tetrachloride vapour and oxygen or oxygen containing gases in a reaction chamber, the molar proportion of titanium tetrachloride and oxygen is from 1 : 1 to 1:6, one or both of these being pre-heated to produce when mixed and irrespective of the heat of reaction, a temperature not below 300 DEG  C.  The reaction gases are passed in two separate streams in the same direction in the reaction chamber, the titanium tetrachloride stream being within the oxygen stream and the ports for the titanium tetrachloride have a perimeter per unit cross-section area greater than 26 cm.-1.  The velocity ratio of oxygen to titanium tetrachloride is less than unity and the velocity of each gas is maintained so that the Reynolds flow number does not exceed 1800 and 500 respectively for the titanium tetrachloride and oxygen in the feed ports immediately prior to admission to the reactor.  The oxygen may contain 0 to 5 per cent water vapour and the titanium tetrachloride may contain 0 to 25 per cent of silicon tetrachloride.  It is preferred that the titanium tetrachloride feed ports are retracted relative to the oxygen feed ports and the ratio of the velocity of oxygen to titanium tetrachloride is preferably from 0.1 to 0.2: 1.  The reaction gases are preferably admitted to the reactor through parallel and preferably concentric ducting, such ducting being straight sided and parallel for a length at least 20 times the hydraulic radius when the gas velocities are associated with a Reynolds flow number of 1800. Shorter lengths of straightsided and parallel ducting may be tolerated for lower gas velocities.  The reaction chamber may be constructed of silica alumina refractory concrete or fired steatite. The latter may be advantageously employed for the construction of the burner ports by shaping it in its raw mineral state.  The reaction chamber is preferably such that a ratio of at least 10 to 1 between the diameter of the reaction chamber and the external diameter of the feed ports is obtained.  Liquid cooling devices may be employed around the burner tips.  A number of examples and comparative examples are provided.

Abstract: 1,184,045. Measuring internal friction electrically. KONINKLIJKE ZWAVELZURFABRIEKEN VOORHEEN KETJEN N.V. March 15, 1967 [March 16, 1966], No. 12120/67. Heading G1N. The internal friction of a material (1, Fig. 1, not shown) is measured in terms of the energy required to maintain constant amplitude oscillations of a torsional oscillator which includes the material (1), and, for example a shaft (5) on a flexible support (15) and an armature having arms (6, 7, 8, 9) and weights (14) thereon; the said energy being proportional to the instantaneous velocity of oscillation and being supplied to coils (10, 12) from an amplifier (23, Fig. 2, not shown) which has its input connected to pick-up coils (11, 13). The pick-up coils 11, 13 measure acceleration or velocity, and the amplifier (23) has its gain automatically adjusted (at 24) by the difference between measured amplitude of oscillation (29) as obtained by integrating the velocity signal or double integrating the acceleration signal, and a reference amplitude (30). The adjustment of the gain control knob (24) is transmitted to an angle measuring device (32) driving a recorder (33), this giving a measure of the energy input to oscillating system and hence of the internal friction of the material. The measuring coils (11, 13) and driving coils (10, 12) all move in respective airgaps in yokes (19, 20, 25, 26), each of which has a central limb carrying a D.C. exciting coil (21, 22, 27, 28). A counterbalance weight (18) is adjustable on a lever arm (16) supporting the oscillating assembly.

Abstract: 1,029,193. Ammunition cartridges. OLIN MATHIESON CHEMICAL CORPORATION. March 27, 1963 [April 12, 1962], No. 12126/63. Heading F3A. A cartridge case 1 has a head 15, rim 16 and tubular wall 19 formed of a thermoplastic resin, and an annular metallic member 2 adjacent the rim 16 to compress the head 15 to a predetermined gauge and to seal and retain a primer 3 in a recess 17 in the lead 15. The metallic member 2 extends around the side wall of the head 15 and has a flanged flare 21 encircling the front and side portions of the rim 16. In one modification the flange is omitted leaving the side of the rim 16 uncovered, and the tubular forward portion of the member 2 is crimped into an annular groove in the side wall. In another modification, the flange is extended to cover the periphery of the base of the rim, the flange being bulged to include a void between itself and the side of the rim to allow slight deformation of the rim without cracking the metal. The member 2 may also be internally serrated to grip the side wall of the head. The case is preferably formed by compressing a stiffened polyolefinic resin, the head 15 being made larger than the required gauge; and the cartridge is assembled by forcing the primer 3 into the recess 17, feeding the case, mouth first, into the flared end of the member 2 until the latter abuts the rim, and crimping the member 2 into position.

The PNPN device 30 may be a silicon controlled rectifier, gate controlled switch or replaced by a complementary pair of transistors. With electronic switch 46 open, the circuit is free-running, producing pulses at a frequency determined by variable resistor 12. If switch 14 is closed, the circuit becomes monostable, and produces a pulse at 20 or 40 after a delay dependent on components 12, 16, each time electronic switch 46 is momentarily opened.

Title: Improvements relating to devices for the automatic regulation of valve stroke in internal combustion engines
IPC: F01L13/00
Filed: 1955-04-27
Abstract: 768,336. Valve gear. DAIMLER-BENZ AKT.-GES. April 27, 1955 [April 27, 1954], No. 12187/55. Class 7 (6). An hydraulic clearance adjusting device for valve gear comprises a fluid pressure space 19, Fig. 1, between a piston 16 and cylinder 10 which is connected to a reservoir enclosed within a resilient sleeve 21, by a passage 25 containing a non-return valve 23 and by a throttling passage 27, e.g. formed by the clearance between the piston 16 and cylinder 10, the passages being arranged in parallel so that when the valve-operating gear opens the valve 14, the fluid can pass from the pressure space 19 to the reservoir 20 only through the throttling passage 27 which is so dimensioned as to give relatively large lost motion and short valve stroke at low engine speeds and relatively small lost motion and long valve stroke at high engine speeds. In Fig. 1 the device is positioned at the upper end of a push rod 10 which is surrounded by a plunger 11 contacting the valve rocker 13 and guided by a bush 26. When the valve 14 is closed the piston 16 is urged away from the cylinder 10 by a spring 17 to take up any clearance in the valve gear, the non-return valve 23 opening to permit free flow of fluid from the reservoir 20 to the pressure space 19. The clearance 27 between the piston 16 and cylinder 10 is, for example, 0.1 to 0.2 mm. which permits a relatively large amount of fluid to escape from the pressure space 19 at low speeds but only a small amount at high speeds. In a modification, Fig. 4, the hydraulic device 110 acts upon a slidable member 111 carrying the pivot of the valve lever, the piston 116 being abutted against a stationary pin 130. A second throttling passage 132 controlled by an adjustable needle valve 133 is also provided, in addition to or instead of the clearance 127 between the piston and cylinder, for the escape of fluid from the pressure space 119 to the reservoir 120.
