Title: Improvements in or relating to internal combustion engineelectric power plants
IPC: H02P9/00
Filed: 1933-03-17
Abstract: 402,304. Systems for transmitting mechanical power; automatic regulation. SULZER FRERES SOC. ANON., Winterthur, Switzerland. March 17, 1933, No. 8098. Convention date, March 22, 1932. [Class 38 (iv).] In a power plant comprising an internalcombustion engine 1 driving an electric generator 2, the speed of the engine is maintained constant by control of the generator excitation in accordance with said speed and hunting is prevented by a simultaneous governor control of fuel supply to the engine in accordance with its speed. The excitation of the generator is controlled by a resistance 5 through a lever 16 and fluid operated piston 14 which is controlled by a piston valve 12 operated by a spring controlled piston 19 responsive to pressure in a pipe system 7, 7<1> which pressure is produced by a pump 6 driven at the speed of the prime mover, and, at the same time, control of motive fluid to the engine at 22, 23 is had from the pump 6 or from a separate centrifugal governor driven at the engine speed. Adjustment of the engine speed may be obtained by adjusting a throttling valve 9 in the pipe system 7 by a lever 10 or by adjusting the pressure of the spring 20. This control may simultaneously control a coarse excitation rheostat in the generator field circuit. When a separate fuel control governor is provided the control of the valve 9 or spring 20 simultaneously effects control of the fuel governor spring pressure. In a modification the lever 22 is provided with an extension pivoted thereon and pivoted on a spring controlled rod vertically slidable in a sleeve on the lever 16 and provided with stops whereby, when the engine speed increases after the excitation resistance 5 has been cut out, further movement of the lever 16 affects the lever 22 so as to reduce the fuel input to the engine even down to its idling value. A perforated adjustable sleeve surrounding the valve 12 may be provided to effect control of torque on the engine, or the torque adjustment may be effected by adjustment of the connection between the member 22 and the valve 12. In the application of the power plant to vehicles, such as locomotives, an additional adjustable resistance may be provided, to enable the driver to control the maximum speed of the vehicle. The system may be arranged to function on a reduction of pressure in the pipe 7.

Title: Improvements relating to electric current limiting apparatus
IPC: H01H73/28
Filed: 1932-03-18
Abstract: 393,719. Automatic circuit-breakers. WALL, G., Rhosneir, Stretford Road, Urmston, Manchester, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. March 18, 1932, No. 8127. [Class 38 (v).] An automatic circuit-breaker for limiting the current of an electric supply comprises movable contacts 37 carried on a blade spring 38 fixed to a pillar 40 so as to be biased away from fixed contacts 30. The contacts are adapted to be closed by a roller 54 carried on a member 53 to which is attached a dead-centre tension spring 57. The member 53 is operated by a mutilated pinion 65 engaging teeth on the right-hand side of member 53. When the switch is closed, the member 53 is prevented from rotating further by the engagement of a pin 56 with a lug 59 on a sector 49 which engages a pinion on a latch 46 which rests against a pivoted plate 17. When the current exceeds a predetermined value, a heating coil in the circuit (not shown) heats a bimetallic strip 2 to tilt the plate 17 and release the latch 46. This allows the sector 49 to rotate and the roller 54 is moved by the spring 57 to allow the switch to open. As the pinion 53 has no teeth on the left-hand side, the switch cannot be held closed by holding the operating member 65. Specification 274,559, [Class 38 (v), Electric switches &c.], is referred to.

Title: Improvements in or relating to measuring apparatus for use with tube, rod, or the like drawing mills
IPC: B21C51/00
Filed: 1948-03-19
Abstract: 645,961. Measuring continuous lengths of materials. GENERAL ELECTRIC CO., Ltd., and DUCKETT, G. C. March 19, 1948, No. 8259. [Class 42 (ii)] [Also in Group XXII] Apparatus for measuring the length of tube, rod or the like drawn on a drawing-mill comprises an electromagnetic clutch 4 and a metering device or a rotary electric switch 8 operating an electric metering device, the clutch including a driven rotor 5 mechanically separated from a driving rotor 3, the rotors having registering sets of teeth 6, one rotor 3 being coupled to a driving part of the mill and the other, 5, driving said metering device or switch 8, the clutch-members rotating in step when an operating coil 14 is energized. A dieplate switch 15 completes the circuit through the clutch-operating coil during drawing and the switch 8 is momentarily closed once per revolution of the driven member 5 to step the meter 11, which sums the length drawn in multiples of, say, 5 feet, or it may be calibrated directly in feet. Alternatively the driven rotor 5 may carry a suitable scale graduated in feet. A steel ball 27 held in a gate device 19 is released through an aperture 25 upon excitation of a solenoid 20 when drawing commences, runs down a channel 18 and enters one of twelve holes in the back of the rotor 3, projecting a small distance proud of the back fade. The ball is carried round by the rotor past contacts 21 which are thereby momentarily closed to step a second meter 22, the period of time from the energization of the solenoid to the closing of the contacts 21 corresponding to, say, one foot of tube &c. drawn. When the ball reaches the top of the rotor 3 it runs out due to the slope of the holes 17, and returns by gravity to the back of the device 19, which it may only re-enter through an aperture 26 when the solenoid is de-energized, i.e. when drawing stops. If the tube &c. breaks during drawing but before the contacts 21 have been closed, the ball carries on round, but closing of the contacts 21 will not actuate the meter 22 since the die-plate switch 15, in series therewith, will be open. Thus the meter 22 counts only the number of tubes &c. drawn, which exceed the predetermined minimum length. Specification 645,962, [Group XXXV], is referred to.

Title: Improvements in or relating to totalizer and totalizer resetting mechanism for cash registers
IPC: G06C7/10
Filed: 1926-11-19
Abstract: 268,376. National Cash Register Co., (Assignees of Goldberg, M. M.). Nov. 21, 1925, [Convention date]. Cash registers; zeroizing-mechanism. - In a machine having a totalizer rocked into and out of engagement with the actuators, the totalizer spindle is locked against rotation, for zeroizing, while the totalizer is away from normal (disengaged) position and the manual means for operating the spindle is normally locked and is released only by the use of a lock-key. The invention is shown applied to the machine described in Specification 261,773. The numeral wheels 116 of the totalizer are provided with the usual pick-up pawls for co-operation with grooves in the spindle 118 which may be turned by gearing 179, 180 and an external knurled disc on the end of shaft 181. Rotation of both the spindle and the shaft is normally prevented by the engagement of mutilated blocks 190, 194 thereon with curved edges of a lever 193 which, however, may be rocked clockwise to clear the blocks by an eccentric pin 201 on the barrel of a proprietor's lock. A rearwardly extending arm 205 of the lever 193 interlocks with a plate 206 secured to the main shaft 49 to prevent simultaneous displacement of the lever and shaft. Another arm of the lever serves to rock a shaft 175 provided with fast arms 176 normally blocking studs 153 on the transfer pawls 143 to prevent rotation of the numeral wheels when the-totalizer is in home position. The rotation of the zeroizing-shaft 181 is limited by abutment of a pin 215, carried by the non-reverse ratchet wheel 216, against a shoulder 217 of a spring-controlled lever 218 slot-pivoted on the shaft 175. When the totalizer is next shifted into engagement with the actuators. a block 219 rigid on the spindle 118 displaces the lever to free it from the pin whereupon the lever ascends past the pin to leave this free for the next zeroizing operation. Specification 268,377 also is referred to.

Title: Improvements in or relating to the construction of floor blocks, wall panels, hollow wall blocks, tiles, and the like
IPC: E04C2/16
Filed: 1944-05-04
Abstract: A floor block, wall panel, hollow wall block, tile, or the like consists of two outer layers bonded to an intermediate layer of lower density, each of the layers being separately moulded by heat and pressure from a mixture of wood waste and natural or synthetic resin. The blocks may be made by first moulding the two outer layers, coating one face of each with a synthetic resin adhesive, applying the wood-waste resin mixture to the coated face of one outer layer, applying the coated face of the other outer layer to the mixture, and subjecting the composite block so formed to the heat and pressure sufficient for production of the required lower density of the inner layer.  The intermediate layer may be cut away in order to reduce the density of the block, or may be cored for the reception of pipes or wires.  Examples of the mixtures moulded are a mixture of urea-formaldehyde resin syrup and coarse wood shavings or chips, of 15 per cent resin content, containing ammonium chloride for acceleration of the polymerization and hardening of the resin, and the product obtained by drying a mixture of 3 parts of sawdust, small wood shavings or wood chips up to 1in. in length and 1 part of a 60 per cent emulsion of phenol-formaldehyde resin in water, and, if desired, phosphoric acid for hardening of the resin.

Title: Glass tube and cane gauging and sorting apparatus
IPC: C03B33/06
Filed: 1955-03-25
Abstract: 797,004. Linear-dimension gauges. OWENSILLINOIS GLASS CO. March 25, 1955 [June 8, 1954], No. 8730/55. Class 106 (2). [Also in Groups XXXVI, XXXVII and XXXVIII] Glass tube &c. 21 is drawn through a diameter gauging mechanism 20, Fig. 1, by a conveyer 23 and is passed to an oscillating cutter 28 which either cuts the tube into lengths or scores it so that it may be broken by star wheels 39. The lengths are then passed by endless belt carriers 220 to a sorting mechanism 230 operated by a stored electrical signal originally produced by movement of the gauging mechanism. The tube 21, Fig. 14, is passed between rolls 41, 42 of the gauging mechanism 20, which rolls are supported in carriers 43, 44 vertically but non- rotatably movable on a pillar 45, the carrier 43 being counterweighted and the carrier 44 being supported on an adjustable spring 68. Relative movement between the rolls 41, 42 due to diameter variation of the tube 21 causes movement between the parts of a differential transformer, the winding 80 being attached to the carrier 44 and the core 82 being adjustably attached to the carrier 43. The output from this transformer is supplied to an electric motor 182, Fig. 2, which is connected through gearing and a belt 185 to a pointer 181 provided with a stylus 186 continuously recording tube diameter measurements on a clockwork driven chart. The recorder also has other pointers which are adjustably positioned to indicate permissible diameter variations and the movements of these pointers are applied through a toothed sector 184b movable by the motor 182 to vary the position of switch elements 193, 270 with respect to switch elements 194, 195. When an undersize or oversize length of tube passes through the gauge 20 the switch 193, 194 breaks, and in so doing causes a signal to pass to relays which transmit impulses to solenoids operating time delay switches (see Group XXXVII). The time delay permits the length of faulty tube to pass from the gauge 20, Fig. 1, through the cutter 28 to a position 22 on conveyers 220, Fig. 8, before the time delay switch is operated, so that when one of these switches is made current is passed to a solenoid 244 which opens a pneumatic valve 241 to operate a piston motor 235. The motor pulls on a spring- tensioned chain 236 to pivot a gate 233 to the dotted line position shown so that the faulty length of tube runs off the conveyer 220 to a rejection rack 232. One of the time delay switches may however, be used to control the operation of separate means for discharging or segregating the oversize from the undersize tubes.
