Title: Rotation measuring device
IPC: G01C19/58
Filed: 1962-09-21
Abstract: 1,015,153. Measuring rotation electrically. STANDARD TELEPHONES & CABLES Ltd. Sept. 21, 1962. [Sept. 26, 1961], No. 36014/62. Heading G1N [Also in Division F4] A rotation sensing device consists an anisotropic paramagnetic element arranged in a magnetic field produced, for example, by means of a circulating lossless current, the field having a fixed orientation in space, and means for sensing changes in the relative angular positions of the element and the field. A crystal 9 of diphenyl picryl hydrazyl is mounted by arm 11 inside a spherical quartz shell 2 having 50 A thick layer 3 of lead on its inner surface. The assembly is cooled sufficiently to make the lead superconductive and a circulating current 10 is induced in it to provide a magnetic field H which acts at right angles to the longitudinal axis of the crystal 9. A coil 12 is wound round the crystal and is energized with radio frequency current at the atomic or nuclear resonant frequency of the crystal at the preset orientation relative to field H. A sensing coil is provided at right angles to field H and to coil 12, and detects the amount of r.f. energy absorbed by the crystal. If the assembly is rotated the magnetic field H remains in its initial direction in space and so acts at a different angle to crystal 9, so changing the resonant frequency. The r.f. frequency is changed to the new resonance frequency which is a function of the angle of rotation. In the preferred arrangement (Fig. 3) the output from a crystal oscillator 46 is frequency modulated at a lower frequency from oscillator 48 and the modulated signal is applied to frequency multiplier 49 whose output is fed to coil 12. The output from the sensing coil is amplified and its phase is compared at 52 with a reference phase from oscillator 48. The low frequency signal detected by the sensing coil will be in phase or out of phase with the oscillator output depending on whether the r.f. signal frequency is above or below the crystal resonance frequency. The output from comparator 52 is applied to a servo control system which controls crystal oscillator 46 until resonance is restored. The frequency of the crystal oscillator is compared at 54 with the frequency of an atomic clock 55. The difference frequency is applied to a frequency counter 56 whose output may control directly the attitude of a vehicle in which the apparatus is mounted, or may be fed to a computer. Additional similar devices may be oriented along different axes to provide additional information. A cryostat for containing the device is described (see Division F4).

Abstract: 1,190,578. Separating liquids. NEIL & SPENCER Ltd. 10 Aug., 1967 [11 Aug., 1966], No. 36082/66. Heading B1D. [Also in Division D1] A separator 51, (Fig. 2) serves to separate mixtures of water and a dry-cleaning solvent, perchlorethylene, which are delivered to inlets A, D which open into vertical pipes 24, 20 extending down to near the bottom of compartments 18, 17 of a tank divided by weir 16. Water, which is the lighter liquid, leaves by overflow (23) and outlet E, and perchlorethylene leaves by main outlet C and restricted outlet B, from respective vertical pipes 22, 25. Weir 16 is higher than the normal, equal, solvent-water interface in compartments 17, 18, and outlet B discharges only during delivery to inlet A. The mixture is delivered to inlet A from a condenser 50, which cools the drying air blown through rotary drum 41 of dry-cleaning apparatus (Fig. 5), and a float (H) in outlet pipe 25 operates a switch to stop the drying air fan 47, the drum 41 and the steam supply to air heater 49, when the solvent flow into inlet A falls below the capacity of outlet B, indicating that clothes in drum 41 are sufficiently dry. The solvent circuit in the first cleaning stage is from tank 45 to pump 44, filter 46, drum 41 and back to the tank. In a second cleaning stage, soap and water are added to solvent in the drum, and this mixture is separately discharged into tank 96. The mixture from tank 96 is pumped to steamheated still 52, which also periodically receives the sludge drained from filter 46, and the vapour from the still passes to a second condenser 54 whose condensate passes to inlet D of separator 51. Separator 5:1 has a lid, and the solvent discharged at B, C passes into tank 55, from which it may be returned to tank 45 or used to rinse clothes in drum 41. Pipes 22, 25 both have air bleeds to prevent siphoning. The valve G restricting outlet B may be set in accordance with the load being cleaned. Two dry-cleaning circuits in parallel may use one separator 51, with two compartments 18.

Title: Improvements in or relating to the treatment of metals in powder form
Inventor: EYRE PHILIP BERNARD
IPC: B22F1/065
Filed: 1956-11-30
Abstract: Spheroidal masses of metal are obtained by moistening metal powder with an inert volatilizable liquid (e.g. an alcohol, aliphatic acid ester, liquid hydrocarbon) to form small aggregates, vibrating the aggregates to give them spherical form, introducing the aggregates into and dispersing them in an inert powder (e.g. alumina, magnesia, alkaline earth metal oxide), heating to drive off the volatizable liquid, then further heating to cause the metal powder in the aggregates to coalesce.  The volatilizable liquid is inert to the metal powder when heated to volatilization; the powder is inert to the metal at the temperature of coalescence.  In an example Ur powder passing a 200 mesh per inch sieve is moistened with amylacetate, and passed through a sieve to form small aggregates which are vibrated to form spheroids.  These are dispersed in powdered lime, the whole being warmed sufficiently to vaporize the amlyacetate.  Further heating is then given in an electric furnace at 1250 DEG C. for 2 hours in argon, followed by cooling in argon.  The lime is removed by sieving and the spherical Ur masses treated with N nitric acid, water, then acetone.  The product may be further heated to increase the density and improve the shape and surface of the spheroids; also rumbling in a stainless steel ball mill may be applied.
