IPC: B24B5/42
Filed: 1929-10-28
Abstract: 337,189. Gustafsson, J. R. Oct. 28, 1929. Rollers, spindles, and the like, treating.-Apparatus for grinding crank-pins on locomotive wheels and journals on wheels for railway cars, consists of a spindle 1 having a flanged end 3, which is clamped against the end of the crank-pin 2 by braces 7, 9 and bolts 8 and is held in axial alignment with the crank-pin by a pin 4 located within the spindle 1 and pressed, so that its pointed end engages the centre mark of the crank pin, by a screw 6 adjustable in the brace 7. The pin 4 is screwed to carry a nut 11 whereby the spindle 1 is pressed against the crank-pin, and on the spindle is slidably mounted a sleeve 13 carrying a rotatable member 16 and a bearing 17. The bearing 17 carries a worm wheel 19 secured to the member 16 and a worm 18 driven by a handle 22, the shaft 20 of which also is supported in a bearing 21 slidable on one of the bolts 8. The member 16 carries on a transverse slide 37, movable by a screw 38, an electric motor 35 carrying on its spindle a grinding-wheel 36, current being led to the motor by cables 33, 34, slip rings 32, and brushes; rotation of the handle 22 causes revolution of the motor and the grinding-wheel around the crank-pin. The grinding- wheel is traversed axially of the crank-pin by a screw 25 journaled in members 27, 28 mounted on the brace 7 and carrying a nut 24 connected by a link 23 to the bearing 17. A marking tool 40 carried by the member 16 is provided to assist in aligning the spindle 1 with the crank-pin and the nuts 10 on the bolts 8, or washers 12 thereon, and the heads of the bolts are provided with convex surfaces engaging the braces to allow of transverse adjustment of the spindle 1. For grinding crank-pins with a lateral projection adapted to carry an eccentric, a yoke member is provided carrying the grinding-wheel, which is driven by belt gearing from the motor.

Title: Production of bipyridyls
Inventor: BRADBURY FRANK RAYMOND
Filed: 1961-09-12
Abstract: Bipyridyls are obtained by treating an interaction product of pyridines and metals with a water-soluble inorganic peroxy compound. The pyridines used for the formation of the metal pyridine compounds may be pyridine itself or pyridine having one or more hydrocarbon substituents. The metal-pyridine compound used as starting material may be, for example, a compound with sodium, magnesium or aluminium. Suitable water-soluble inorganic peroxy compounds are, for example, hydrogen peroxide and per acids and their salts such as sodium peroxide, sodium perborate, sodium percarbonate and ammonium persulphate and they are preferably used as aqueous solutions or slurries.

Abstract: 429,834. Permutation locks. DONOVAN, A. M., The Lawns, Upminster Road, Hornchurch, Essex. Nov. 24, 1933, No. 32949. [Class 44] [See also Group XXXI] A bolt 6, subject to the setting of permutation locking rings 10, is slidably mounted in a bracket 8 secured to a clamping member 4 adapted to embrace a tubular stay of a bicycle or the like in the vicinity of the chain or sprocket wheel so that the bolt may be projected between the spokes thereof, being normally withdrawn to a limited extent. The nut 21 securing the clamping bolt 20, is located within the bracket 8 so that it cannot be manipulated when the locking bolt 6 is in position. The locking rings 10, which are of the kind comprising inner and outer parts to enable the code to be altered, are rotatable on a boss 9 forming part of the bracket 8 and through which the bolt 6 passes, radial lugs 11 on the bolt protruding through an axial slot in the boss to co-operate with corresponding passages in the rings. The rings, together with dividing plates 16 restrained from rotation by lugs 17 engaging an axial groove in the boss, are retained on the boss 9 by a face plate 12, a threaded stem 13 of which passes through the boss and is secured by a nut 14. Rotation of the face plate when in position is prevented by a triangular boss 15 thereon engaging a corresponding recess in the boss 9. Rotation of the nut 14, when the bolt 6 is in position, is prevented by the closeness of these members, the nut being of ordinary hexagonal form or formed with serrations to engage the bolt 6, Specification 392,501 being referred to in this connection. Alternatively, the face plate 12 may be secured to the boss 9 by a bayonet connection or slot and dovetail joint or by screw threads. The bolt 6, which is provided with a handle 19, may be grooved to carry a spring clip or staple 18 to limit withdrawal when unlocked or, instead of a clip, a sleeve or collar may be mounted loosely on the bolt normally in rear of a lug thereon, a groove in the collar being brought into alignment with the lug when it is desired to dismount the bolt.

Abstract: 584,786. Radiolocation. STANDARD TELEPHONES & CABLES, Ltd., and BEATTY, W. A. Dec. 29, 1939, No. 33056. [Class 40 (v)] In a system for locating moving objects such as aeroplanes in flight by measuring the time that elapses between the transmission of a pulse signal and the reception due to reflection from the aeroplane of the same pulse signal, the train of pulses, sent out by the transmitter is such that either the leading or the trailing edges of the pulses occur at equal time intervals but the pulses are of variable durations corresponding to the amplitudes of a sound or other signal wave giving intelligence for instance relative to the direction or angle of propagation or to the bearings of objects located from the transmitter. The transmitter may be centrally located with regard to anti-aircraft batteries located over a wide area, each battery location having a radio receiver tuned to the transmitted frequency. The transmitter may employ two propagation methods, the first employing a sharply defined beam for obtaining bearings, while the second is omni-directional on the same frequency. The two transmissions may be given different polarisations. Directional and omni-directional receivers together with electronic time-measuring apparatus may be provided at each battery position, the central transmitter indicating the approximate position of the aircraft and the individual batteries locating more accurately. Specification 523,575 is referred to.

Title: Improvements in or relating to voltage regulators
IPC: H02J7/22
Filed: 1962-09-07
Abstract: 940,630. Automatic voltage control. ROBERT BOSCH G.m.b.H. Sept. 7, 1962 [Sept. 7, 1961], No. 34359/62. Heading G3R. A known voltage regulator 14, of the vibrating contact type, controlling the output of a dynamo 10 is modified by the provision of a semi-conductor element 25 which is heated by the main load current and which is connected across the exciting coil 20 of the regulator whereby the regulating action is made load-dependent. The resistance of the element 25 rises only slightly up to a predetermined temperature, and then rises very sharply with further increase in temperature. Up to a predetermined value of load current, the regulator acts in the usual manner; when the current exceeds this value, the resistance of element 25 rises steeply due to increased temperature and causes the coil 20 to regulate for a lower voltage, thus protecting the dynamo from overload. The element 25 may be soldered to a flattened portion of the main conductor, and may be located in the regulator 14 or in the generator 10 (Fig. 2, not shown). In a modification (Fig. 3, not shown) the element 25 is connected in series with a coil which acts in opposition to the coil 20.
