Abstract: In the case of a motor-driven drive roller 1, which is designed to drive a conveyor belt 10 and itself to be driven by a motor (not shown) inside the drive roller, the non-rotating parts of the motor being fixed to a shaft 3, which is torsionally fixed by means of a bolt 13 to a rotating armature 12, which is in turn displaceable but non-rotatably supported in frame 11, of which only a small part is shown, the novelty resides in the fact that the bolt 13, which in hitherto known drive rollers of this type was only used to fix the shaft to the rotating armature, is carried right through and can be adjusted whilst bearing against a bearing face 16 in the frame 11. A considerable simplification is thereby achieved, since in the hitherto known drive rollers of this type, special elements were required for this adjustment of the shaft in relation to the frame. <IMAGE>

Title: Improvements in and relating to worms and to the process of manufacturing such worms
IPC: F16H1/16
Filed: 1921-01-03
Abstract: 156,682. Krupp Akt.-Ges., F. Jan. 13, 1920, [Conventoin date]. Addition to 155,583, [Class 80 (i), Gearing, Belt &c.]. Void [Published under Sect. 91 of the Act]. Gear-cutting.-In a worm of the type described in the parent Specificarion, the two helical surfaces of the thread are respectively generated by two straight lines which are equally inclined to a transverse section of the worm and equidistant from the worm axis by an amount at least equal to the radius of the wormcore. Such a worm may be cut by means of a disc-shaped milling-cutter operating with both the side faces and the peripheral face. The generator 1, 3, moving axially and simultaneously rotating in contact with the core cylinder a generates the profile b and the symmetrical dotted curve b<1> within the groove of the thread while the similar generator 2, 4 generates the profile c and the symmetrical curve C<1>. The shape of the profile may be varied by altering the inclination of the generators to the worm section. The helical surfaces b &c. may thus be produced by a turning-tool moving along the generators 1, 3, and 2, 4, respectively. Alternatively, the profile c may be produced by moving the tool along a generator 2<1>, 4<1> parallel to the generator 1, 3. Thus both surfaces may be produced by a doubleedged cutting-tool moving along the line 1, 3, 4<1>, 2<1> one edge generating the profile b during the first half of the path and the other generating the profile c during the latter half. The worm may also be cut by means of a disc-shaped milling- cutter having its axis of rotation at right-angles to the line 1, 3, 2<1>, 4<1> and parallel to a plane dd which passes through the worm axis and is parallel to the line 1, 3, 2<1>, 4<1>. The cutting axis is moved forwards parallel to itself until it emerges from the groove of the thread, this movement being repeated if necessary after a feed movement towards the worm axis. By altering the inclination of the milling-cutter axis to the worm axis, different profiles may be produced and a grinding-wheel of similar section to the cutter may be employed to finish the worm. Instead of displacing the milling-cutter axis parallel to itself to feed the cutter across the work, the cutter bearing may be rotated about a point sufficiently distant from the worm axis, or, by making the cutter of sufficient diameter, this cross-feed may be dispensed with and only a feed movement towards the worm axis will be required.

Patent GB-1174012-A (GB)
Title: Sonar Installations
IPC: G01S15/42
Filed: 1968-01-02
Abstract: 1,174,012. Sonar systems. SIMONSEN & MUSTAD A.S. 2 Jan., 1968 [4 Jan., 1967], No. 297/68. Heading H4D. A saw-tooth voltage generator is provided in a sonar installation to control the duration of angular sweep of the electroacoustic transducer. When locating a target found during a broad sweep it is desirable to sweep the transducer beam back and forth over a narrow sector around the target. In the Fig. 1 embodiment the drive direction of transducer sweep motor 2 is periodically reversed by energizing relays 3, 4 alternately. Each time peak voltage is reached in saw-tooth generator 9, trigger circuit 8 applies a switching pulse to bi-stable circuit 7 and also resets the sawtooth generator to zero. Bi-stable 7 opens gates 5, 6 alternately, for actuating relays 3, 4. The duration of a sweep is thus the period of the sawtooth. In one arrangement this period is controlled by a clock pulse generator. In a second arrangement a device 21 geared to the transducer drive provides voltage pulses for incremental rotation of the transducer and these pulses build up a sawtooth voltage of staircase waveform in generator 9, whereby triggering of circuit 8 and reversal of the drive direction will occur after a given angle of sweep instead of after a given time. This second arrangement ensures that the angle of sweep is the same in both directions even when hydrodynamic forces on the transducer affect the drive speed unequally in the two directions. The automatic reversal of drive direction may be overridden by (a) closing switch 13 to trigger circuit 8, whereby the drive direction reverses and is maintained in the new direction while switch 13 remains closed, or (b) moving ganged switches 10 to the L or R position, whereby the sawtooth generator 9 output is clamped to a voltage below the peak value and reversal of the drive direction is inhibited.

Title: A process for preparing sulfolane
Inventor: ABEN PIETER CORNELIS
IPC: C07D333/48
Filed: 1967-01-04
Abstract: Sulpholene is converted into sulpholane by hydrogenation in the presence of a solid hydrogenation catalyst, the sulpholene being used in a solution, containing at least 10% by weight of sulpholene and optionally up to 80% sulpholane and/or up to 80% of propanol and/or isopropanol, which is introduced into a hydrogenation zone, the hydrogenation temperature being from 0 DEG  to 50 DEG  C. and the partial pressure of hydrogen being from 5 to 200 kg./cm.2 and the hydrogenation being discontinued prior to or when the activity of the catalyst has diminished to such an extent as to cause only 80% conversion in a time originally sufficient to obtain 100% conversion. Preferably the sulpholene is introduced into the hydrogenation zone as a solution in one or more of the following:- sulpholane, acetone, C1-C3 alcohols, or cycloaliphatic ethers having 4 ring carbon atoms and one or two ether oxygen atoms in the molecule. Suitable catalysts are nickel, nickel-chromium alloys and metals of the platinum group preferably on a carrier such as silica.  If desired the catalyst may be mixed with a porous particulate material, e.g. a porous catalyst carrier comprising silica and/or one or more silicates and/or alumina and/or one or more aluminates or a molecular sieve material such as a zeolite. If desired the hydrogenation may be carried out as a part of a two-stage process in the first of which sulpholene is produced by the addition of sulphur dioxide to butadiene, the sulpholene (optionally after isolation) being then hydrogenated in the second stage.  The hydrogenation catalyst may be regenerated by heating the spent catalyst with oxygen-containing gas at 400-500 DEG  C. and subsequently with hydrogen at 100-500 DEG  C.  Preferably the spent catalyst is heated at 20-500 DEG  C. with an inert gas, e.g. nitrogen, before the treatment with oxygen.

A frequency synthesiser comprises a first variable frequency oscillator 1 producing an output frequency variable from 0À899-29À898 mc/s. in steps of 1 kc./s. by means of an A.F.C. loop comprising a variable divider 16, a comparator 17, and a reference frequency source 19; a second variable frequency oscillator 2 variable over the range 10-20 mc/s. in steps of 1 kc./s. by a similar A.F.C. loop and feeding a divider 22 and mixer 23 followed by a filter 24 to provide a signal variable from 101-102 kc./s. in steps of 0À1 cycles/second; and a third variable frequency oscillator 26 which provides the output signal over a range 1-30 mc/s. in steps of 0À1 cycles/second, the difference frequency between the first and third oscillators 1 and 26 being derived by a mixer 28 and compared with the output of filter 24 to derive an error signal controlling the oscillator 26. Preferably the A.F.C. loops controlling oscillators 1 and 2 share a common variable divider 16 and comparator 17 on a time-sharing base. The divider 16 may be a counter, and in one counting cycle the switches 15, 20 and 21 are as shown; the re-set pulse changes over the switches, so that in the next counting cycle the other A.F.C. loop is completed and so on. The division ratio is normally different in the two loops and may range from 899 to 29,898 for oscillator 1 and from 10,000 to 20,000 for oscillator 2. The comparator 17 provides a coarse error signal which drives stepping motor 3 or 4, and a fine error signal which controls reactance 9 or 10. The stepping motors control variable capacitors associated with the oscillators, and motor 3 also controls a variable capacitor 27 associated with the third oscillator 26. A crystal oscillator 19 operating at 100 kc./s. provides one input to the mixer 23 and also provides the reference signal for comparator 17 via a fixed divider 18.
