Title: Improvements in or relating to toy devices or motors
IPC: A63H29/22
Filed: 1918-12-30
Abstract: 141,105. O'Leary, M. V. Dec. 30, 1918. Reciprocating and oscillating machines; electromagnets.-A toy electric or other motor is adapted for use as a stationary motor for driving machinery and for attachment to an auxiliary frame to serve as a toy locomotive &c. The motor frame includes two slotted side plates 1, 2 between which an electromagnet 10 is fixed by bolts 8. A vibrating armature 14 is supported on the magnet by a flat spring 12, and its vibratory motion is converted into rotary movement of a driving-drum 6 and pulleys 7 by means of a flexible band 21 wound around the drum; one end of the band is connected to the armature, and the other end to an adjustable arm 24. A make-and-break switch 15, 17 is included in the circuit of the electromagnet for operation by continuous current; the switch may be rendered inoperative, when used on an alternating-current supply. Terminals 18. 20 are mounted on the side plates. To convert the motor into a truck, the motor is inverted and joined to an auxiliary frame 27 having side pieces with studs 29 designed to snap into openings in the side plates 1, 2. The frame 27 has wheels 31 for running on rails Y, and a trolly or collector 34 for engaging a third rail X. A spring arm 35 attached to the collector 34 makes contact with the terminal 18. The pulleys 7 serve as wheels when the motor is operating as a truck. To prevent sparking at the contacts 15. 17, the electromagnet coil may be built up of flat copper strips A, B separated by paper and wound around the laminated core 9, the ends of the strips being connected to the battery D and switch contacts as shown; it is stated that this construction has the effect of a condenser bridged across the contacts.

Title: Improvements in or relating to fluid-pressure control or indicating apparatus
IPC: G01F1/38
Filed: 1947-08-08
Abstract: 645,010. Controlling combustion. ELECTROFLO METERS CO., Ltd. Aug. 8, 1947, No. 21820. Convention date, June 29, 1939. [Class 51(i)] [Also in Group XXIX] A control device for use in a fluid-pressure indicating or control system comprises a U-tube containing a sealing liquid and pivotally mounted at an acute angle to the horizontal so that it can be unbalanced by the controlling force and means responsive to the unbalance is provided to create a force tending to rebalance the tubes. In an illustration of the invention, a U-tube 10, 14, Fig. 2. containing mercury 12 is pivoted at 16 and carries a sliding weight 18 to adjust its initial balanced position. Pressure is applied by a fluid from a conduit 22 to limb 14 of the tube whereby the mercury is depressed in that limb and raised in the other. This unbalances the tube and causes it to tilt so that the limb 10 partially closes a nozzle 32 to which a fluid under pressure is supplied from a conduit 28 past a restriction. The resultant increase in pressure upstream of the nozzle is applied to a diaphragm 38 which applies a force to the tube to rebalance it. A stop 34 prevents the tube from swinging too far back. In one embodiment the limbs of the U-tube are made concentric and the tube carries a piston working in a cylinder to constitute a dashpot preventing fluttering. In applying the invention to measuring the flow of a fluid, the differential pressures across a restriction in the conduit along which the fluid flows are applied to the two sides of a diaphragm which is directly connected to the U-tube, and the resultant movement of the diaphragm tilts the tube. The increased regulating pressure produced by the movement of the tube is applied, not to diaphragm 38, but to the appropriate limb of the tube to rectify the liquid levels therein and so rebalance it. The flow can then be read off on a gauge responsive to the regulated pressure. In a system for regulating fuel and air supplies for combustion, a master controlling pressure is applied through a line 52. Fig. 6, to a device 44 similar to that shown in Fig. 1, and the resultant regulated pressure is applied through a line 122 to a diaphragm 120 which acts on a lever 114. The latter actuates a throttle valve 100 in the first fuel line, but it is also acted upon by a further diaphragm 118 responsive to the differential pressures across a restriction 98 in the fuel line. The fuel flowing in a second line 102 is controlled in a similar manner. The two master controlling pressures are also applied to interconnected diaphragms 132, 134 which actuate a movable vane 144 co-operating with a nozzle 142 to regulate the pressure in a line 140, the latter being supplied with a pressure fluid flowing past a restriction 138. The regulated pressure is applied to a further device similar to 44 in order to control a throttle valve 112 in an air supply line. The air flow acts as an additional control to valve 112 through the medium of a restriction 110 and diaphragm 152. '

Abstract: 860,660. Cleaning metal strip. OSBORN MANUFACTURING CO. July 11, 1957 [May 9, 1957], No. 22024/57. Class 99(2). Apparatus for brushing a length of metal strip S comprises one or more stands each having a pair of cylindrical, rotary brushes, at least one of which is power driven, adapted to engage opposite sides of the strip passing therebetween, and mechanism for shifting the brushes relatively to each other in parallel directions normal to the pass line of the strip so as to permit the strip to be flexed over each brush. The brushes have a dense fill adapted to support the flexing of the strip when the latter is subjected to longitudinal tension. As shown, a horizontally-disposed, continuously-travelling, metal strip S passes between a pair of parallel, opposed cylindrical brushes 9, 10 mounted on shafts 11, 12 journalled in blocks 5, 6 and 7, 8 mounted for vertical reciprocation in spaced frames 1, 2, both shafts being driven in the same or opposite direction by hydraulic or electric motors 34, 35. The axes of the brushes lie in a common plane inclined at an angle to the vertical of from 20 to 45 degrees, and the brushes may comprise bristles of hard, crimped steel wire coated with a film of vibration damping plastic such as nylon, or plastic filaments, tampico fibre, or plastic coated glass fibre filaments. Fluid-pressure-regulated plungers 13, 14 are fitted in the lower blocks 6, 8 to urge the blocks 5, 6 and 7, 8 and brushes apart, and screw means 15, 16 driven through bevel gear units 27, 28 driven from shafts 24, 25 coupled by a worm gear reduction unit and clutch 26 to an electric motor 23 urge the blocks 5, 7 downwardly against the force of the plungers ; screw-means 17, 18 to move the blocks 6, 8 upwardly are driven from a motor 29 through a reduction gear unit and clutch, shafts 30, 31, and bevel gear units 32, 33. The screw-means may be driven in unison or independently. The brushes may be of buffing material and have a granular abrasive applied thereto. Periodically, the direction of rotation of the brushes may be reversed, and the driven speeds of the brushes may be 5000 to 12,000 surface feet per minute, the rate of travel of the strip being very much less, but the brushes may be driven at greater speeds when the work engaging surfaces thereof are moving in the same direction of travel of the strip. Where mill scale is to be removed from the strip, preferably, such scale is fractured by flexing the strip back and forth prior to the brushing operation. Specifications 736,217, 736,253, 850,461 and 854,766 are referred to.

Abstract: 821,059. Coated laminated fabrics. FENNER & CO. Ltd., J. H. July 10, 1957 [July 24, 1956], No. 22819/56. Class 140. The surface resistivity of impregnated and/or coated multiple-ply textile fabric belting, e.g. power transmission or conveyer belting, comprises applying a coating of electrically-conductive carbon, e.g. carbon black, to an outer surface or surfaces of the belting after impregnation and/or coating of the fabric, said surface or surfaces being in a form capable of accepting and holding the carbon coating, e.g. a paste or liquid layer which may be consolidated by decreasing the liquid content thereof. The fabric may consist of various plies of fabric held together by binding threads and which is produced in one weaving operation, and may be impregnated and/or coated with a natural or synthetic rubber or a polyvinyl compound, e.g. polyvinyl chloride. The fabric belting may be produced by applying a layer of the carbon in powder form to the outer surface or surfaces of belting produced according to Specification 770,524 and thereafter consolidating the impregnated woven fabric and the carbon coating by heat-treatment which may be assisted by the application of pressure to gell the polyvinyl compound. The fabric may have a sheathing coat of a polyvinyl compound and the carbon may be applied to the outer surface or surfaces of the fabric and/or to the outer surface or surfaces of the sheathing coat. In the Figure, multiple-ply textile fabric 1 is impregnated in bath 3, is coated with carbon powder produced within chamber 5 by beater 6 and blown through nozzle 5b by fan 7. The fabric then passes through gelling chamber 14, between pressure rollers 16 and through cooling chamber 18 prior to being taken up on roll 19.

Title: Radiation measuring instrument
IPC: G01T1/20
Filed: 1965-05-28
Abstract: 1,100,693. Measuring radiation. NORTH AMERICAN AVIATION, Inc. May 28, 1965 [June 1, 1964], No.22843/65. Heading G1A. Apparatus for measuring the intensity of first source of radiation is provided with a second source of radiation of different energy and means responsive to signals derived from the radiation from the second source to adjust the sensitivity of the radiation detector or its circuit. The invention is applied to apparatus as disclosed in Specification 885,102 for measuring the volume of fuel in a tank. Gamma radiation from a Ce137 or Co60 source that has passed through the tank 32 is incident upon a scintillation counter to produce pulses of a height in a range L 1 . These pulses trigger only circuit 56 and pass to an integrating amplifier 80 feeding a pulse rate meter 24. The second source 34 is alpha emitting Am241 which produces pulses in scintillation counter 20 of a height centred on the division between ranges L 2  and L 3 ,so that half the Am241 pulses pass threshold circuit 60 and half only pass threshold circuit 58. If the sensitivity of the scintillation counter varies the distribution of the Am241 pulses between ranges L 2  and L 3 will change. The difference between the count rates in these channels is derived by an amplifier and used together with the actual values of the count rate to control the sensitivity of the photo-multiplier to keep the count rates equal. The sum of the count rates may also be used to adjust the gain of the pulse shaping circuits 66, 68, 70 to compensate for natural decay of the sources (which have been chosen to be approximately equal). As in Specification 885,102 a number of fuel tanks may be monitored by separate systems using the same output display.
