Title: Process for preparing d-ribose
IPC: C25B3/25
Filed: 1964-08-07
Abstract: D-ribinose is made electrolytically from d-ribonolactone by mixing the latter with an electrolyte containing a mineral acid salt of an amine, and using this as catholyte with a mercury cathode, or an amalgamated metal, e.g. lead, silver, or zinc.  The anolyte is an aqueous mineral acid.  The amine may be primary, secondary, or tertiary, e.g. the sulphate, nitrate, hydrochloride, or phosphate of methylamine, benzylamine, heptylamine, or of alkylolamines.  The catholyte should be maintained at pH 3 to 5 by adding a mineral acid during the reduction which is effected at 10-40  DEG C. The anolyte is preferably a 10% solution of an acid, and is separated from the catholyte by a porous diaphragm, e.g. a cup made of alundum or unglazed porcelain.

Title: Improvements relating to electric motors
Inventor: NICOL KENNETH MARTIN
IPC: H02K7/12
Filed: 1960-09-22
Abstract: 999,754. Motor driving arrangements. LIMIT ENGINEERING GROUP Ltd. Sept. 22, 1961 [Sept. 22, 1960], No. 32566/60. Heading H2A. In a motor driving arrangement the axially moving rotor of the motor is prevented from movement due to the magnetic pull between the rotor and stator by spring means until the motor has gathered speed so that the engagement of clutch plates connected to the load and carried by the rotor is delayed. As shown the shaft 4 of a motor carries a member 12 provided with a flange 5, having a facing of friction material 6, keyed to the shaft 4 so that it is slidable along the shaft but rotatable with it. The member 12 and associated flange 5 are held against the end of the shaft by spring 7 compressed between washer 8, held in position by bolt 9, and a shoulder 10 on the member spaced from the end of the shaft by spacer 11. When the motor is energized the rotor does not move axially to the right until the magnetic pull between the rotor and stator is sufficient to overcome the bias of a spring (not shown) biasing the rotor and motor shaft to the left. However, on reaching a sufficiently fast motor speed the motor connections may be switched from star to delta connections to increase the flux density and hence the magnetic pull between the rotor and stator sufficient to overcome the spring bias and move the rotor to the left, when the flange 5 moves into engagement with a pulley 3 mounted on ball-bearings 2 on the motor frame 1 and is held in contact with the pulley 3 by spring 7. In a single-phase motor an appropriate change in magnetic flux and pull may be effected by the use of a tapped winding and an appropriate switch or by changing the magnitude of the supply voltage to the motor. Alternatively the flux may be changed automatically by a centrifugal switch which operates to apply full voltage to the motor when it has run up to the required speed.

Abstract: 466,354. Hinges. SILENTBLOC, Ltd., and JELLEY, S. W. Nov. 26, 1935, No. 32723. [Class 65 (ii)] In a flexible joint or support of the kind comprising an outer cylindrical member A, an inner cylindrical tube or pin B, and a bushing C of rubber or the like interposed and compressed between the members A, B so that it adheres to them, the members A, B are provided with abutments A<2>, F respectively engaging opposite ends of the rubber bushing C and adjusting means are provided whereby one of the abutments can be moved towards or away from the other to vary the axial force exerted thereby on the bushing independently of any force exerted by an axial load on the joint. In the form shown, the abutment F is supported by a nut E screwed on the end of member B, but it may be integral with the nut E or may, according to the Provisional Specification, bear against the head of, or be threaded on, a bolt which passes through the sleeve B. The other end of member B has a fixed abutment B3 which bears against the abutment A<2> on the outer member A through a rubber washer to locate the parts when not under load. The abutments and the end surfaces of the bushing may be shaped, as shown, to provide increasing surfaces of engagement as the joint yields to axial loads, or may provide unvarying engaging surfaces. The abutment B<3> may bear against the end of the bush C, without an interposed washer, instead of against the abutment A<2>, and in this case, according to the Provisional Specification, B<3> may be made adjustable instead of, or as well as, F. A<1> is a fixing flange for the member A. In a modification, Fig. 4 (not shown), two joints similar to that shown, but with fixed abutments F, may be placed end to end, one being reversed so that the abutments F are together, their inner members being fixed together or integral while the flanges A<1> of the outer members are connected by adjustable means so that they can be drawn together to exert axial force on both the bushings simultaneously. According to the Provisional Specification, in this arrangement the outer members may also be rigidly connected, the abutments at their outer ends being made adjustable or adjustable abutments being provided at the outer ends of the inner member. Either or each of the abutments for applying the axial force to the bushings may be adjustable relatively to the member carrying it. In all the arrangements described, the abutments may be interchanged between the inner and outer members. The end faces of the bushings and abutments may be shaped as described in Specification 434,583.

IPC: G01L7/16
Filed: 1961-09-13
Abstract: 976, 293. Pressure ratio determination; pendulum lever apparatus, comparing forces. GENERAL ELECTRIC CO. Sept. 13, 1961, No. 32848/61. Headings G1L and G1W. Apparatus for measuring the ratio of two pressures P 1 , P 2 , using the principle of a pivoted lever (70 in the schematic diagram Fig. 2, corresponding to 38 in Fig. 1) having different mechanical advantage in different positions to give balance for different ratios of the two pressure-derived forces, has pistons 26, 28 linked to the lever 38 (pivoted at 40) and acted on, respectively, by pressure P 2  and a pressure P 3  proportional to P 1  and derived from P 1  by means of a choked orifice 58, the pressure P 1  being applied, via inlet 23 to chamber 24. to act against both pistons. The ratio (P 1 - P 2 )/(P 1 - P 3 ) is thus measured and, because P 3  = kP 2  where k is constant, gives the ratio P 1 /P 2  as a function of one variable, namely, the angular displacement # 1  (see Fig. 2) of the lever 38. The pistons 26, 28 are formed as zones of a sphere and are rigidly fixed to the rods 34, 36 so that when the latter are canted, the pistons remain in contact with the cylinder walls. In the embodiment of Fig. 4, pressures P 1  - P 4 , one, or two, of which may be standard or zero, are applied to pairs of bellows 80, 81 and 82, 83, the bellows in each pair acting in opposition to move rods 89, 91 by the resultant pressure |P 2 - P 1 |, |P 4 -P 3 |. The angular displacement of the lever 85 gives the ratio (P 2  - P 1 )/(P 4  - P 3 ). Magnetic transducers 46, 48, 50, Fig. 1, or 98, Fig. 7, convert the lever movements into electric signals.

Title: Improvements in or relating to means for transversely guiding or registering moving bands or webs
IPC: B65H23/038
Filed: 1932-11-28
Abstract: 410,859. Endless - belt conveyers. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and WHITELEY, A. L., 16, Vernon Avenue, Hillmorton Paddox, Rugby. Nov. 28, 1932, No. 33670. [Class 78 (i).] In a mechanism for regulating the lateral position of a moving web or band to prevent overcorrection, two detecting-devices are provided, actuated respectively by a movement of the web to the right and left of a desired position, together with a roller lapped by the web and having a normal position at right-angles to the plane of an edge of the web and adapted to be displaced angularly by electromagneticallycontrolled motive means actuated by the detecting-devices to effect a suitable lateral displacement of the web when one of the detecting-devices is operated, while the same motive means is simultaneously operative to move the detecting-devices transversely of the web in the direction of the displacement. Lateral displacement of the band conveyer 1 is controlled by horizontal displacement of a roller 2, which is pivoted about a vertical pin 3 at one end, and is provided at the other end with a block 5 into which is inserted a screwed spindle 6 adapted to be rotated in either direction by a reversible motor 9 which, when energized on account of lateral deviation of the band 1, thereby causes the guide roller 2 to pivot in such a direction as to correct this deviation. The motor is controlled by two detecting-devices comprising photo-electric cells 10, 11 receiving light through slits 12, 13, one or other of which is adapted to be covered according to the side to which the band deviates. Each cell controls a relay which operates according to which slit is obscured to start the motor in the desired direction, and the correction continues until the slit is again uncovered. To prevent overcorrection, the light-sensitive devices are mounted on a bar 14 which is coupled by a crank 15 to a shaft 16 connected by adjustable gearing to the spindle 6, so that when the band deviates and obscures a slit 12 or 13, the motor 9 is actuated to adjust the guide roller 2 and the photo-electric cell is also moved in such a direction that the slit is uncovered earlier than if the cell were stationary. The cells 10, 11 may be replaced by selenium cells or electrical contacts.
