Title: Simulated twelve pole stepping motor having eight actual poles
IPC: H02K37/04
Filed: 1971-09-22
Abstract: 1344142 Control of stepping motors SUPERIOR ELECTRIC CO 22 Sept 1971 [22 Sept 1970] 44211/71 Heading H2J A stepping motor of conventional construction and having eight stator poles or multiples thereof with teeth opposed to teeth on the rotor, is provided with pole windings which are arranged and controlled to produce a rotating magnetic field composed of three asymmetrical magnetic areas, two of which are aligned with respective poles and the third of which is aligned with the area between a pair of adjacent poles. The invention is applied to a conventional stepping motor having a permanent magnet rotor, Fig. 1 (not shown), whose stator has poles 15-1 ... 15-8 carrying windings 16-1 ... 16-8 each of which is bifilar to include separate portions 16-1a, 16-1b &c., each pair of portions being arranged to produce a north or a south pole according to which portion is energized. The winding portions are connected in four phases 24a, 24a<SP>1</SP>, 24b and 24b<SP>1</SP> energized through respective switches from a battery 25. The switches are controlled to energize two phases at a time in a four-step sequence, each step of which produces the three asymmetrical magnetic areas 26, 27, 28 whose resultant field is balanced along a diametric line aligned with the area 26 to produce a stable position of the rotor. A typical operating sequence is described to produce rotation of the field as shown in Figs. 4a-4d, the effective movement of the field being 30 degrees per step and the direction of rotation being determined by whether the rotor has more or less teeth than the stator. The conventional one-half tooth pitch displacement of the two end caps of the rotor may be replaced by corresponding displacement of the two sets of stator poles with the end caps aligned. In another embodiment in which the invention is applied to a conventional variable reluctance type stepping motor, Fig. 5 (not shown), the windings 16-1-16-8 are not bifilar and are arranged in four phases with two windings per phase, Fig. 6 (not shown), to produce energization of only four poles per step, the pair of poles associated with the third area being respectively north and south, Figs. 7a-7d (not shown). Alternatively the windings may be rearranged, Fig. 8 (not shown) to produce alternate pairs of north and south poles associated with the third area, Figs. 9a-9d (not shown). In all the described embodiments, the pitches of the stator and rotor teeth may be the same with the stator poles being unequally spaced.

Inventor: ROYSTON MICHAEL GOERGE
IPC: F28D3/00
Filed: 1960-12-23
Abstract: In concentrating fruit juice, the juice F1, Fig. 1, flows downwardly through an evaporator P in which vapour S, e.g. steam, stripping volatile essences from the juice, flows upwardly.  The essence vapour F3 then passes through a condenser 4 and a scrubber 7. The stripped juice F2 passes through another evaporator 1 to yield concentrated stripped juice 2.  The condensed vapours 5 from the condenser 4, and recovered essences 8, from the scrubber, are mixed with the concentrated stripped juice 2. In the evaporator P, the juice F1 may flow down each side of corrugated plates P2, Fig. 2, located between hollow, e.g. corrugated, plates P1 and P3 through which steam is passed.  The plates P2 may be provide with punched-out flaps 9, Fig. 3. In an alternative construction of the evaporator P, the plates P1 and P3 are not hollow and steam is passed upwardly between them and the plates P2. <PICT:0954378/C3/1> <PICT:0954378/C3/2> <PICT:0954378/C3/3>

Abstract: 981,627. Physiological tests. ASTRO-SPACE LABORATORIES Inc. Nov. 23, 1962' No. 44433/62. Heading A5K. An equipment for observing and measuring heart beats by means of the vibrations they induce in the body employs a platform, to receive the patient, mounted on an air bearing, to avoid the possibility of vibrations being communicated from the building or other extraneous sources. The platform 24, on which the patient is located by means of straps 64 and a saddle member 62, is supported on an upper bearing member 36, the lower surface of which is part spherical of large radius of curvature. This surface mates with the upper surface of the lower bearing member 54 and the interior cavity 52 of the latter is supplied with air or gas, under pressure, which, escaping through a ring of apertures in the upper wall, supports the platform in a frictionless manner. Wide swings of the platform during the initial balancing of the patient are prevented by a flanged ring 66 which is moved upwards to embrace the upper bearing member. The vibrations induced in the patient by the heart are detected by a strain-gauge type of accelerometer, in which a mass of high inertia is supported on strain wires attached to the platform and which are stretched or relieved differentially by the vibrations. The gauge is connected electrically to a recording instrument which may also be associated with a timer or electrocardiograph.

Title: Coinitiation of bisulfite addition reactions
IPC: C07C303/32
Filed: 1961-12-19
Abstract: Alkyl sulphonates are prepared by adding an aqueous solution of a bisulphite salt to a mixture of terminal olefins in the presence of a solvent selected from methanol, ethanol, isopropanol, n-propanol or mixtures thereof and sufficient peroxide to form a molar ratio of olefin to peroxide of 1 : 0.0005 to 1 : 0.10, maintaining the pH of the reaction mixture between 3.5 and 8.0 and simultaneously passing a molecular oxygen containing gas through the reaction mixture at a rate equivalent to at least 0.1 volume of air per minute. The olefins are preferably those having 5 to 20 carbon atoms although the mixture may contain secondary or internal double-band olefins not having a terminal double band. It is desirable to subject the olefins to mild acid treatment or passage through an adsorbent material, e.g. silica gel, prior to reaction to remove impurities and inhibitors. The bisulphate salt may be an amine, alkaline earth metal or, preferably, ammonium or an alkali metal bisulphite and an aqueous solution of 1 to 6 molar is found satisfactory.  The peroxide may be inorganic, e.g. hydrogen or sodium peroxide, or organic, e.g. benzoyl- or methylethylketone-peroxide, preferably having the peroxy group attached to at least one tertiary carbon atom, being especially t-butyl perbenzoate.  The gas, preferably air or oxygen, is bubbled directly through the reaction mixture which is preferably at pH 4.5 to 7.5 and 20 DEG  to 200 DEG  C.  In the batch process it is of advantage to perform the reaction in the presence of up to 15 molar per cent of elefin of preformed sulphonate.  The alkyl sulphonate product may be isolated from the reaction product by treatment with a light hydrocarbon, e.g. n-propane, or dilution with water to remove unreacted hydrocarbons and with a desalting solvent, e.g. n-propanol, to remove organic salts.  Alternatively, the reaction product may be desalted by crystallization prior to the removal of unreacted hydrocarbons.  The alkyl sulphonate products may be used as detergents.
