Title: Improvements relating to balancing machines
Inventor: CLIFTON JAMES BERNARD MCCARTHY
IPC: G01M1/22
Filed: 1953-03-25
Abstract: 726,107. Balancing machines. SMALL ELECTRIC MOTORS, Ltd. March 25, 1953, No. 8297/53. Class 40 (1) In a balancing machine in which the rotor is mounted in bearings provided with electrical tranducers the outputs of which are combined and operate, via a frequency-selective network, indicators of the magnitude and angular position of the necessary correcting masses in the two balancing planes, the tuning of the network is automatically maintained in correspondence with the frequency of the transducer signals if the speed of the rotor varies. This avoids errors which would otherwise arise from variations of the phase of the signal with respect to the position of the unbalance. In the system described, the position of the correcting masses is indicated stroboscopically, each pulse, resulting from the combination of the transducer signals, flashing a lamp to illuminate a scale on the rotor. Circuit arrangements. The combined signal from the transducers after amplification in tuned amplifiers 8, 14 passes to a circuit 26 for flashing the stroboscopic lamp and to a full wave rectifier 24 which supplies an indicator 25 of the extent of the unbalance. With the aid of a tapping to the rectifier cathode and a capacitor 29, a double frequency signal is passed to a control path comprising a tuned amplifier 30, clipper 33 and discriminator stage 34, whose tuned circuit is resonant at a frequency somewhat above twice the normal rotation frequecy, so that it operates on the substantially linear flank of its response curve giving across secondary 37 a voltage proportional to frequency. The secondary supplies a rectifier via frequency meter 38, and part of the rectified output is applied as bias, through smoothing inductance 40, to the first amplifier valve 8 to compensate for the loss of amplification as the dynamic impedance of the resonant circuit falls and to reactor valves 13, 19, 20 which adjust the frequency to which the amplifiers 8, 14 are tuned. The action is modified by a bias dependent on the strength of the signal through capacitor 29, which signal is rectified between grid and cathode of valve 30 and fed to the first amplifier valve and the reactor valves through 43, 42, to neutralize any strength-dependent component passing the valves 30, 33, 34. The phase of the voltage supplied to the stroboscope triggering circuit is thereby maintained constant with respect to the phase of the control box output.

Abstract: 794,199. Perforating machines. BUCKLEY, M., and BUCKLEY, D., [trading as HIRST, BUCKLEY & CO.]. March 26, 1956 [March 28, 1955], No. 8941/55. Class 31 (2). [Also in Groups XVI and XXIX] In sheet feeding apparatus wherein sheets are moved in a second direction after reaching their limit of travel in a first direction, there is disposed adjacent the limit of travel a suction nozzle connected to a source of suction by means of a control device which is responsive to a pressure fall in the nozzle, and which is connected to sheet-gripping means for feeding the sheets in the second direction, the arrangement being that when a sheet overlies the suction nozzle, the control device will be actuated to cause operation of the sheet-gripping means. As shown, the invention is applied to a paper-perforating machine comprising two sets of apparatus arranged to provide perforations in two directions across sheets. Sheets 50 are separated one by one from a pile by a suction roller 51 on to the feed belts 12 in apparatus 10 which feed each sheet past perforating discs 13 up to an adjustable stop 20 where it overlies a suction nozzle 21. The nozzle is connected by a flexible pipe 24 to a control device 25 connected by a pipe 42 to a source of suction. When the end of the nozzle 21 is obturated by a sheet, suction builds up in the control device 25 to move a piston therein so that suction can be established between the pipe 45 and a pair of rotating suction rollers mounted in a cross-shaft 48, whereupon these rollers feed the sheet at right angles to the first direction on to feed belts 12<SP>1</SP> in another apparatus 11 which has further perforating discs therein. The suction rollers are in heads 43, 44; suction is applied thereto by pipes 46, 47, 41, and chambers disposed against holes in the sides of the rollers. The side holes communicate with holes in the circumference of the rollers, and top plates 49 ensure that only one axially disposed row of holes is presented at a time to a sheet. The control device 25 comprises a valve body in which a piston is slidable, against the action of gravity and a light spring, to establish communication between pipes 41, 42, when the pressure above the piston falls due to the closing of the nozzle 21 by a sheet. A by-pass is arranged between the pipe 42 and the space above the piston which communicates with the pipe 42.

Abstract: Wood substitutes for the manufacture of flooring, tiles, parquet flooring, furniture, &c. are prepared by removing the cuticle or bark wholly or in part from the stalks or twigs of plants or trees, especially of heather, birch, willow and privet, arranging them substantially parallel to one another and then binding them together with a bonding material or cement under pressure so that the stalks or twigs assume a polygonal shape in cross-section, with each one fitting closely against adjacent ones, and the product has the appearance in cross-section of a honeycomb.  After the bark or cuticle has been removed from the twigs, e.g. by sand spraying, the twigs may be treated with a fungicide, insecticide or colouring agent and then either slowly dried to a uniform moisture-content of about 12-16 per cent or treated for a short time at 150 DEG  C. until the moisture-content of the outer layer reaches 10 per cent.  The bonding agent is then applied either by immersion, brushing or spraying and the twigs are arranged as far as possible parallel to each other, e.g. by allowing them to fall from a height and catching them between rollers, and then subjected to a pressure of about 1000 lbs. per sq. in.  The final product may be composed of bonded layers with the twigs in one layer parallel or transverse to those in an adjacent layer.  The first Provisional Specification describes also the application of heat during pressing, modifications in which the twigs are not parallel, nor have had the bark removed, and a product with spaced voids formed as a result of using lower pressures, and the second Provisional Specification the use of chemical means, e.g. dilute caustic soda solution, to remove the bark from the twigs.
