Title: Controlling vibration of wheel and tyre assemblies
IPC: G01M1/22
Filed: 1966-09-15
Abstract: 1,086,549. Measuring wheel shake electrically. GENERAL MOTORS CORPORATION. Sept. 15, 1966 [Sept. 30, 1965], No. 41282/66. Heading G1N. A wheel and tyre assembly 12 (Fig. 1) is driven by a motor 20 via a drum 18, and variations in the radial distance due to radial runout, caused by a combination of static unbalance and high spots on the tyre surface, are measured by a displacement or vibration transducer 28 whose output signal is compared with a reference signal from a photo-cell 24 and rotating mark 26 to determine the magnitude and angular position of the compensating mass required to remove the unbalance. The speed of rotation is just above that producing wheel hop resonance, and at this speed the signal from transducer 28 lags by 90 on the actual displacement, due to inertia effects.

Filed: 1974-09-24
Abstract: 1441078 Purification of polyphosphoric acid HOECHST AG 24 Sept 1974 [20 Oct 1973] 41498/74 Heading C1A Polyphosphoric acid is dearsenicated by heating with a + I or + III phosphorus-oxygencompound, whereupon the oxo compound disproportionates and generates an off-gas containing arsenic (as AsH 3 ) which is removed. Temperature of 200-400 C. may be used, as may concentrations of the oxo-compound of 0À1-50% (by weight based on the polyphosphoric acid). The process is assisted by the passage of an inert gas, such as N 2  or Ar, through the reactor, the reaction mixture being stirred. The +I and +III phosphorus compound mentioned comprise phosphorous acid, hypophosphorous acid, phosphites and hypophosphites.

Title: Improvements in or relating to radiation detectors
Inventor: TURCK BERNARD
IPC: G01T1/22
Filed: 1963-10-21
Abstract: 1,022,566. Radiation detector. COMMISSARIAT A L'ENERGIE ATOMIQUE. Oct. 21, 1963 [Oct. 22, 1962],No. 41530/63. Heading G1A. A device for detecting and determining strontium 90 and yttrium 90 in water by application of the Cerenkov effect, comprises two photomultipliers 9, 10 having their cathodes 7, 8 arranged close to the surface of the water 2, a receptacle 3 for the water having reflecting sides 4 and base 6, and a coincidence circuit to which is applied pulses produced by the photomultipliers. Light produced by the Cerenkov effect passes through the quartz windows to the cathodes of the short-resolution time photomultipliers, which are applied with stabilized high voltages through conductors 12,13. Pulses produced pass through identical channels 15, 16 to a coincidence circuit 14. This is arranged to eliminate pulses which are not a result of the Cerenkov effect but are due to thermal emission from the cathode or dynodes of a photomultiplier, usually being obtained at any one time in only one of the photomultipliers. Such a pulse received by the coincidence circuit 14 results in an output pulse of much smaller magnitude, which is eliminated by a threshold device 27. The channels 15,16 each consist of a preamplifier, 17,18, a wave form device, 19, 20 which calibrates pulses by their duration, an impedance converter 23, 24, and an adjustable delay device, which allows for differences between the transmission times of the two photomultiplier/preamplifier assemblies. The effect of cosmic (or y) rays can be eliminated by a channel 31 from one photomultiplier to an anticoincidence circuit 28, which also receives the pulses from the coincidence circuit 14 via an amplifier 29. The channel 31 has an amplifier preceded by a threshold device 32 which transmits all pulses above a certain magnitude (corresponding to that produced by cosmic rays). Thus cosmic ray pulses cancel out in the anti-coincidence circuit 28, and the Cerenkov pulses pass through an impedance converter 36, to a counting device 34. This comprises a threshold device 37, which eliminates unwanted pulses, produced by the anti-coincidence circuit, and the counter 38 itself. Exemplary values of photomultiplier gain and resolution time and of the liquid volume, are given.

Abstract: 1474965 Drying materials METALLGESELLSHAFT AG 26 Sept 1974 [1 Oct 1973] 41982/74 Heading F4G A process of drying moist inorganic materials comprises the steps of feeding the materials into a drying shaft 6 as a high density stream countercurrent to a flow of hot drying gases which rise at a velocity of 2 to 30 metres per second and which have an inlet temperature of 200‹ to 1000‹ C., so that the moist materials agglomerate and are dried at the same time. Fines entrained by the hot drying gases are collected in a cyclone 11 and are added to the moist materials before they are charged into the drying shaft 6. Preferably the hot gases which are produced in a burner 4 and blown by a blower 5 rise at a velocity of 8 to 25 metres per second. The agglomerated materials are cooled by cold gas in the lower portion 8 of the drying shaft 6. The exhaust gases pass through a wet scrubbing plant 12.

Title: Control circuits for dc motors
IPC: H02P7/29
Filed: 1971-09-09
Abstract: 1360676 Control of DC motors GENERAL ELECTRIC CO 9 Sept 1971 [11 Sept 1970] 42101/71 Heading H2J [Also in Division H3] In a thyristor control circuit for a D.C. motor, a first signal fires an auxiliary thyristor to charge a commutating capacitor and subsequently fires a main thyristor which also serves to reverse the charge, whereafter a second signal again fires the auxiliary thyristor and thus extinguishes the main thyristor. A positive pulse at IN fires SCR2 to charge C1. After a delay, transformer T2 saturates and a capacitor C2 is charged sufficiently to break down Z1 and fire SCK1, thus to energize the motor. Capacitor C1 discharges through D3 following the voltage across a secondary winding JK and reverses the capacitor charge until T1 saturates. A subsequent negative pulse at IN fires SCR2 again, causing C1 to discharge via SCR1 and extinguish it. Current from the motor flowing through T1, SCR2 and C1 maintains a negative voltage on the thysistor to assist commutation. In due course T2 saturates, removing the gate bias from SCR2. Reverse current flows through SCR2, T1 and D2 until the inductive energy in T1 is transferred to C1 whereupon SCR2 is extinguished. The voltage on C1 now decays through D3. Contacts F1, F2, RV1 and RV2 allow the motor to be reversed and B1 provides direct energization of the motor.

Title: Improvements in or relating to the production of phosphonitrilic trimers
IPC: C07F9/6593
Filed: 1964-10-16
Abstract: Cis- and trans-2,4,6-trichloro-2,4,6-triphenyltriphosphonitriles are prepared by effecting reaction between chlorine gas and phenylphosphorus dichloride in a suspension of finely-divided ammonium chloride in an inert liquid reaction medium at 60-150 DEG C.  The reaction may be effected (a) by passing chlorine gas slowly into a suspension of the ammonium chloride in a solution of phenylphosphorus dichloride in the inert liquid or (b) by passing phenylphosphorus dichloride and chlorine gas simultaneously into the suspension of the ammonium chloride.  Preferably, the ammonium chloride has an average particle size below 10 microns and may be prepared by passing gas streams of ammonia and hydrogen chloride into an inert liquid which is the same as that used in the preparation of the phosphonitrilic trimers.  Suitable inert liquids are saturated aliphatic hydrocarbons containing 6 to 10 carbon atoms aliphatic helogenated hydrocarbons which are not readily dehydrohalogenated and halogenated benzenes containing 1 to 3 halogen atoms.  The cis- and trans-trimers may be recovered from the reaction mixture by filtering it to remove ammonium chloride, evaporating the filtrate to dryness and purifying the resulting product with a paraffin hydrocarbon containing 4 to 7 carbon atoms.

Abstract: 924,937. Twisting-spindles; ring-spinning. NIHON KEORI CO. Ltd. Dec. 22, 1960 [Dec. 24, 1959; July 18, 1960 (5); Aug. 26, 1960], No. 44169/60. Classes 120 (2) and 120 (3). A ring device for use in a spinning-machine comprises an uninterrupted ring 1 of ferromagnetic material held in a floating condition inside a ring-shaped holder 2 also of ferromagnetic material, by a magnetic force, a ring- shaped gap 15 being formed between the ring and the holder through which the roving travels in operation. In the embodiment shown in Fig. 1 the ring and holder are made of steel and are magnetized radially so that the ring floats in space with the magnetic repelling force between similar magnetic poles exerted between the ring and the holder balanced with the gravitational force exerted on the ring. If the gap 15 is too large the weight of the ring 1 may be increased by adding an iron ring 13, Fig. 4a, to the ring 1. In a modification, Fig. 5, the ring 16 and the holder 19 are magnetized vertically so that repulsive forces are set up between the upper surfaces and the lower surfaces thereof. A non-magnetic ring 22 is fitted inside the holder 19 to weaken the attracting force exerted between the ring and the holder. In each of the embodiments above the ring may be made to float by attracting forces by reversing the polarity of either the ring or the holder. In a further embodiment, Fig. 6, a non- magnetic spacer 24 is fitted to the holder 23 and has projections 25 having screws 26 attached thereto so that it can be fixed in any angular position. The radial thickness of the spacer 24 is not uniform and it is rotated to form a uniform width gap between the ring 22 and the holder 23 when the magnetism is uneven. To enable the ring 22 to be removed from the holder 23 the latter may be formed with two depressions 27, Fig. 7 (not shown). Alternatively the ring 22 may have a supplementary ring 28, Fig. 8 (not shown), of non- magnetic material attached thereto. In a further modification, Fig. 9, a slot 29 is formed in the holder 23 and a non-magnetic support 31 therefor to facilitate the insertion of the yarn into the gap. The slot 29 may be vertical or oblique. In an alternative embodiment, Fig. 12, to control excessive rising of the ring 22, a non-magnetic support 34 which surrounds the ring carries several spindles 38 each urged towards the ring centre by a spring 37 and limited by a stop 39. A freely rotatable disc 40 is attached to each spindle and checks the rising of the ring due to yarn tension. In a modification, Fig. 13, a tube 45 containing a ball 44 urged outwardly by a spring 43 may be provided in each of a number of recesses 42 provided in the holder 23. Alternatively, Fig. 14 (not shown), this arrangement may be provided in recesses in the ring, the holder being formed with an inwardly turned flange against which the balls 44 abut. A hand tool, Fig. 17, for picking up the ring 58 comprises projections 53, 54 between which the ring 58 is engaged and a ring 51 to fit the operator's finger.
