Title: Improvements in or relating to Measuring Apparatus
Inventor: KRUGER PHILIP JOHANNES
IPC: G01B7/02
Filed: 1966-07-29
Abstract: 1,159,993. Measuring linear dimensions electrically. SOUTH AFRICAN INVENTIONS DEVELOPMENT. Oct. 17, 1967 [July 29,1966], No. 30803/66. Heading G1N. [Also in Division D1] The mean lenght L of the fibres 2, Fig. 1, in a sliver is determined by attaching one end of the sliver to a clamp 3 by means of which it is drawn through a friction element such as a comb 1 at a constant speed, the force in the sliver being measure by strain gauges 15 (or non- electric means) from which signals representing maximum force P, and total work done A are obtained and used to derive the mean length. In the embodiment, A and P are substituted in the formula, mean length L=KA/P<SP>X</SP> where K and X are experimentally determined constants; alternatively, an experimentally obtained graph or table may be used to give L. The strain gauges 15 are attached to a flexible plate 5 which transmits the drive from a threaded shaft 19, engaging a carriage 16, to a rod 12 attached to the clamp 3. The strain gauges may be attached alternatively to the comb assembly 1. A further comb 10 removes loose fibres. The strain gauges are connected in a bridge circuit (22, Fig. 2, not shown) energized by an oscillator (23, 24, 26), and feeding an amplifier (29, 30) and a detector (32). The unidirectional pulses from the detector (32) charge an integrating capacitor (33) which is periodically discharged by a unijunction transistor (34) at a frequency dependent on the magnitude of the measured force. The integral of the measured force with respect to time, which represents work done, as the speed of the clamp 3 is constant, is derived in a counter (not shown), the unijunction transistor (34) driving a mono-stable (36, 37) which drives the counter via a transistor amplifier (38). In a non-electric embodiment a disc rotates about a vertical axis at constant speed having a follower disc displaced radially across its surface by means of a resilient arm subjected to the drawing force of the sliver, so that the number of rotations of the follower disc is an integral of the force with time. The length dispersion of the fibres in the sliver may also be obtained from the above measurements together with a measurement of the longest fibres left after the drawing operation.

Patent GB-353792-A (GB)
Title: An improved process for the catalytic hydrogenation of hydrocarbon oils
IPC: C10G47/00
Filed: 1930-10-16
Abstract: <PICT:0353792/III/1> In the treatment of heavy hydrocarbon oils by passage with hydrogen at elevated temperature and pressure through a catalytic zone, the flow of oil is discontinued when the catalyst activity falls off, a solvent for tarry matter is passed through the catalytic zone for a prolonged period and then the flow of heavy oil is continued.  The solvent may be naphtha, kerosene, acetone, carbon tetrachloride or carbon disulphide.  Heavy oil from a tank 1 flows through a heat-exchanger 5 and preheater 7 into a reaction vessel 9 containing solid catalyst 10.  Hydrogen is injected by a pipe 12 and the products leaving by the pipe 13 are condensed and separated in the condenser 14 and catch-pot 15.  The hydrogen is purified and re-cycled by line 11.  The catalyst may consist of mixtures of oxides of metals of the sixth group with or without zinc oxide, aluminium oxide, and oxides of the metals of the alkali, alkaline earth, or rare earth groups; when its activity falls below a suitable value the flow of heavy oil is discontinued and a light kerosene distillate from tank 2 is circulated with the hydrogen.  The catalyst is thereby revivefied and the kerosene is freed from sulphur impurities.

Title: Improvements in or relating to controlling aircraft
IPC: G05D1/04
Filed: 1938-10-27
Abstract: 576,359. Gyroscopic apparatus. MEREDITH, F. W., and GARDNER, G. W. H. Oct. 27, 1938, No. 31132. [Class 97 (iii)] [Also in Group XXIX] In an aeroplane, a sight is stabilised to the vertical during banked turns by rotatably mounting the sight about an axis in the plane of symmetry of the aeroplane not coincident with the yawing or vertical axis of the aeroplane, and when a turn is required, the sight is rotated thus giving an indication to a human pilot, or being communicated to an automatic pilot, and the aeroplane is turned at a rate depending on the extent of the original movement of the sight. As shown, the arrow g, Fig. 1, indicates the direction of flight, and the sight 2 can be rotated about an axis 3 by means of a flexible cable from a control handle 4. Movement of the latter varies the spring loading pressure-regulating valves 17, Fig. 2, interposed in an air pressure line 14 which leads through conduits 15, 16 to a servopiston 5. The differential pressures obtained from movement of the control handle act on the piston 5 which through a lever 6 moves the inner gimbal ring of a gyroscope and causes the latter to precess. The fulcrum 7 of the lever 6 is adjustable to allow for different flight speeds, and if the setting is indicated airspeed, compensation for the effect of density on rotor speed is obtained. The gyroscope is mounted on a support 1 and has 3 degrees of freedom to measure directly a function of the deviations is azimuth and roll. Movement of the outer gimbal ring actuates a valve b controlling a servo-piston c connected to the ailerons through a lever h. A follow-up effect is obtained from a lever d. An anti-topple device comprises a valve e actuated from the inner gimbal ring and controlling a servo-piston f connected to the outer gimbal ring.

Title: Improvements in or relating to the manufacture of nitrocellulose compositions
IPC: C08J3/22
Filed: 1935-11-11
Abstract: Solid heavily pigmented nitrocellulose compositions are made by incorporating together nitrocellulose, a pigment, a plasticizer of poor solvent power for nitrocellulose and a high boiling solvent for nitrocellulose, at least a part of the plasticizer remaining undissolved by the nitrocellulose.  The incorporation may be assisted by a medium or low boiling diluent such as ethyl alcohol, isopropyl alcohol, or isopropyl ether.  Suitable plasticizers are castor olive, linseed, or tea seed oil, or butyl stearate; or mixtures of oil and trialkyl or triaryl phosphate may be used.  The high boiling solvent may be butyl acetate, amyl acetate, and the ethyl ether of ethylene glycol acetate.  In an example, carbon black is first mixed with ethyl alcohol, butyl alcohol and butyl acetate, alcohol-wet nitrocellulose is then added, followed by tricresyl phosphate and castor oil, and then a further quantity of alcohol-wet nitrocellulose; the mixture is transferred to a malaxator and sprinkled with a mixture of ethyl alcohol, butyl alcohol and butyl acetate, and then stored in sealed containers; after further malaxating, the material is formed into thin slabs, dried, and cut or broken into pieces.  The pigment may be of mineral or inorganic type, or it may be of organic nature, such as diacetyl benzidine, naphthyl urea, anthraquinone, anthracene, resins and lakes.  The pigmented product is employed as a convenient means for introducing pigments in the manufacture of plastics, lacquers, films, filaments &c., having a basis of nitrocellulose, organic derivatives of cellulose, resins, &c.

Title: Shutter control systems for air flow regulation
IPC: F01P7/12
Filed: 1973-07-03
Abstract: 1388375 Radiator shutters KYSOR INDUSTRIAL CORP 3 July 1973 [3 July 1972] 31708/73 Heading F4S In a shutter assembly for controlling cooling air flow over radiator and air conditioner condenser elements of an automotive vehicle, wherein the shutters 14 are biased (e.g. by springs 31) towards the open position, and wherein actuating means 24 are provided to move the shutters towards their closed position, a second actuating means 30 is provided which can act in co-operation with the biasing means 31 to partly open the shutters from their closed position against the action of the actuating means 24. As shown, the shutters 14 (biased to the open position by springs 31) are closable against the action of the springs by an hydraulic cylinder 24 pressurized from a source 25 when flow is permitted through supply lines 35, 34 by a thermally actuated valve 32 attached, e.g. to the engine block of the vehicle. The shutters may e.g. be closed when the engine needs to be rapidly heated on starting up. Pressure fluid is also supplied to a conduit 80 leading via a solenoid valve 54 to an hydraulic cylinder 30 acting when operative to open the shutters 14. If, when the shutters are closed, the vehicle air conditioning system 38 is switched on, an electromagnetic clutch 50 is energized to connect an engine-driven pulley 48 with the air compressor 36; and at the same time the solenoid valve 54 is energized to permit fluid from the line 80 to pressurize the hydraulic cylinder 30. This force, aided by the springs 31, can overcome the shutter closing force applied by the cylinder 24 and the shutters are opened by an amount (e.g. # in.) adjustably controlled by the amount of play permitted in a lost motion linkage (62, 70, 74, Figs. 3, 4) provided between the piston of the hydraulic cylinder 30 and the shutter actuating bar 22. It is said that other hydraulic or electromechanical actuators may replace the actuators 24, 30. The condenser of the air conditioning system may form the grill of the vehicle radiator.

Abstract: 1,061,783. Structural connection for buildings. Aug. 13, 1963 [Aug. 17, 1962; Jan. 4, 1963], Nos. 31751/62 and 565/63. Heading E1A. In a building structure, a floor or roof member 102 is connected to vertical supporting member 24 by a dry load bearing tapered spigot and tapered socket point 31b, 32b associated with further load bearing mating surfaces 35, 44 transverse to the axis of the joint. One exemplified embodiment employs tubular spigot members secured to the upper and lower ends of hollow columns for engagement in sockets formed in members cast into the four corners of rectangular roof or floor slabs. Lateral positioning of the roof or floor slabs is determined by the mutual abutment ribs 55 on the sides of the socket members and relative rotation of the connected members is prevented by spherical members which locate in opposed hemispherical recesses 53 in the surfaces 35, 44. A modified form of spigot member is described with reference to Fig. 9 (not shown). Superimposed vertical members may be connected by the spigot and socket joints to lower and upper faces of a floor or roof member. The end faces of adjacent spigots of superimposed vertical members may or may not be in load bearing contact with each other. A tensioning member may be passed longitudinally through hollow columns and spigots.
