Title: Box Unstacking Machine
Inventor: TAMPLIN NORMAN THOMAS
IPC: B65G59/06
Filed: 1966-02-24
Abstract: 1,179,561. Stacking and unstacking machines. N. T. TAMPLIN. 24 May, 1967 [24 Feb., 1966], No. 8178/66. Heading B8C. A machine for stacking and unstacking boxes trays &c. 71 and of the kind in which an elevator platform raises or lowers each box between a pair of catches which support the lowermost box of the stack includes a trip mechanism spring-biasing the catches to the inner box engaging or outer disengaging position according to whether it is set for stacking or unstacking. In unstacking, the elevator, on moving downwards, operates the trip to engage the catches beneath the last but one box so that the boxes are unstacked from below. In stacking, the catches remain inwardly biased and are moved apart by the box being lifted to the stack base. The elevator is operated by a scissor mechanism (30-35), Fig. I (not shown), including a ram (37). The trip mechanism includes an over-centre device comprising a rod 51 pivoted at 53 to a lug 54 on a rod 43 carrying a spring 58 and slider 55. A lever 56 is pivoted to the slider and to the machine frame at 57. Stops 59 limit the travel of the lever 56. When in the unstacking position shown, the spring 58 biases the rod 43 to the left to retract the catches but the lever 56 may be swung manually to rest against the other stop 59 when the catches are biased to the closed position for stacking. A spring-backed cam member 66 pivoted on the elevator engages a roller 65 on the lug 54 to move the bar 43 to the right to engage the catches beneath a box. When stacking, the catches 42 are pressed open by a box lifted between them but down again beneath the box so allowing a stack to form. An alternative trip device. Fig. 5, for unstacking, has a lever 75 operated by a rod 76 on the elevator to move the catches 42 as before. For stacking, the trip is made inoperative and spring means (not shown) biases the catches to the inner position. The machine may be made automatic and a device to count the number of boxes in a stack to stop stacking at the required number included.

Title: Pump for pumping liquids containing ce-lulose or other fibre suspensions
IPC: F04D29/22
Filed: 1973-02-20
Abstract: 1412488 Centrifugal pumps JONKOPINGS MEKANISKA WERKSTADS AB 20 Feb 1973 [21 Feb 1972] 8358/73 Heading F1C In a pump for liquids containing cellulose or other fibre suspensions and having at least one impeller through which the whole of the liquid to be pumped is passed, the inlet edge of each impeller vane 1 is contained substantially in a plane perpendicular to the impeller axis, and the inlet angle of each vane is at least 50 degrees. The inlet angle may be as large as 120 degrees but is preferably between 70 degrees and 110 degrees. As shown in Fig. 4, the inlet angle is preferably substantially 90 degrees. The use of a large inlet angle causes increased turbulence 11, which serves to carry away pulp fibres tending to lodge on the inlet edge 10 of the vane. To assist further in dislodging fibres, the inlet edge 10 is as shown bulbously thickened on that side which faces in the direction of rotation of the impeller. Vanes 15 on the back of the impeller reduce the axial thrust on the impeller and also oppose the tendency of fibres to penetrate into the gap 17 between the impeller and the core plate 16. To ward off any fibres which do penetrate the gap, the gap is made wider at the radially outer end than nearer the pump shaft 2.

Title: Improvements in electric musical instruments
IPC: G10H3/08
Filed: 1920-03-22
Abstract: 142,447. Hugoniot, C. E. April 30,1919, [Convention date]. Instruments with sonorous plates.-Relates to instruments in which sounds having any desired tone are produced synthetically by the action of superimposed undulatory electric currents which pass through the receiver of a loud-speaking telephone. Fig. 1 shows a front elevation of an electric generator for producing superimposed currents. Fig. 2 shows a modification, Fig. 4 an appliance for controlling strength and pitch, and Fig. 5 a section of a detail. The rotor of an alternator comprises a Gramme winding composed of a series of elements a - - f, Fig. 1, and the field magnet is made up of groups of electrumagnets A<1> - - A<6>, each group consisting of a different number. The electro-magnets are supplied with continuous current, the excitation of each group is separately adjustable by means of a rheostat, and gruups may be removed, shortcircuited, or set at a slight angle as required. Polar extensions of various shapes or sizes may be used. The current collected at the brushes B<1>, E<2> is taken to a telephone receiver. The strength of sound for a given note may be varied bv a rheostat acting on the field magnet assemblage or by one interpolated between the armature and the telephone receiver. Pitch is varied by altering the speed of the armature. In the modification shown in Fig. 2, the field magnet consists of groups of poles 1 - - 6, and the armature is formed of groups C1 - - C6 of different numbers of winds carried on a rotating disk. The control mechanism, Fig. 4, consists of a paper strip travelling on rolls i, j and marked with lines h corresponding to the music to be played, which is followed with a style l moved by hand, and connected by links m, n to the rheostat o<1>, in series with the motor driving the alternator, and the rheostat o<2> arranged to prevent variation of voltage when the speed of the motor is varied. The style l is constructed with a small rheostat whose resistance varies with the pressure applied by the player, as shown in Fig. 5, the ebony tube p is filled with pieces of graphite &c., and the sliding part is in contact with a spring q. In a modified style, a spring-pressed piston carries a contact which moves over a spirally coiled wire resistance. Two or more alternators may be coupled together and operated from a single style. The pole-pieces employed may be toothed to reproduce the shape of the vibration of a given sound.

Abstract: 726,244. Water-tube steam boilers; steam superheaters. BABCOCK & WILCOX, Ltd. March 27, 1953 [March 27, 1952], No. 8522/53. Classes 123 (2) and 123 (3). A steam boiler is fired by two rows of cyclone furnaces A and B each arranged as described in Specification 552,747, [Group XII], and operating at temperatures above the ash-slagging temperature of the fuel, the furnace gas passing into a common secondary furnace 10 and then through slag screens 94 and 96 into a steam generating tube lined radiation chamber 12 in the upper part of which is disposed a pendant, radiant superheater 14, 16 constructed for example as described in Specification 720,833. The gases leave chamber 12 through an outlet 18 and flow downwardly through a pass 22 which is divided by vertical partitions into three separate passes, the outer of which locate convection superheaters such as 24 whilst the middle pass locates a convection reheater, the gases passing to an air heater 32 through a breeching 28. The cyclone furnaces and furnace chamber 10 are lined with generating-tubes which, together with those of chamber 12, extend between a steam-and-water drum 46 and a water drum 44, To temper the furnace gases entering the radiant superheater and so to prevent deposition of slag therein, cool flue gases are admixed with the furnace gases near the superheater inlet whilst to control the temperature of superheat, a further quantity of flue gas is introduced into the secondary furnace. The flue gas is withdrawn from breeching 28 at 34 by a fan 158, the tempering gas being passed through a damper-controlled duct to a chamber 38 whence it flows into chamber 12 through ports controlled by adjustable louvres whilst the superheat-control gas is passed to a chamber 42 whence it flows downwardly into furnace 10. Specification 675,410 also is referred to.

Title: Improvements in or relating to the control of flying shears
IPC: B23D36/00
Filed: 1965-03-01
Abstract: 1,099,274. Automatic control of flying shears. ZAVODY V.I. LENINA PLZEN, NARODNI PODNIK. March 1, 1965 [March 2, 1964], No.8579/65. Heading G3R. In a control system for flying shears, signals UV1, UV2 representing respectively the speed of the material to be cut and the shear-speed are subtracted to form signal UV which is applied to integrator 1. When the material is being sheared, the speeds of the shears and material are synchronized, and, immediately afterwards, contact 1B is closed to discharge capacitor C through resistor R2. The integrator 1 is thus prevented from generating a signal during the discharge period, whereby signal VSl, representing the difference between the required cut length and the distance travelled by the shear-blades between two successive cuts, is fed to controller RS. The latter responds to vary the shear-speed in accordance with the magnitude and sense of the input signal. When the capacitor has discharged, the integrator comes into operation to generate signal US which is subtracted from the signal USl to produce a decreasing signal USR. When the latter has been reduced to zero, the cutting operation is effected.

Title: Improvements relating to Anti-Wheelspin Devices for Motor Vehicles.
Inventor: WILSON RONALD HOLDSWORTH
IPC: B60T8/175
Filed: 1966-02-28
Abstract: 1,177,502. Differential braking systems. KIRKSTALL FORGE ENG. Ltd. 25 May, 1967 [28 Feb., 1966], No. 8682/66. Headings F2D and F2F. [Also in Division G1] An anti-wheelspin device for road or rail vehicles with independently braked wheels driven through a differential comprises an auxiliary differential with two members driven from the wheels and a third member whose speed and direction of rotation depend on the difference of the speeds of the first two members, the third member driving a device which applies braking force to the faster rotating wheel. In Fig. 1, the speeds of the driving wheels 10, 11 are sensed by take-off wheels 22, 23 engaging the disc brakes 24, 25 and transmitted via cables 26, 27 to planet carriers 35, 36 of a compound epicyclic gear train forming an auxiliary differential 28. The planet wheels 33, 34 engage respectively sun-wheels 31, 32 of which 31 is mounted on a hollow shaft 40 freely rotatable on the carrier 35 while 32 is fixed to the housing via a sleeve 39. As long as the driving wheels 10, 11 rotate at the same speed, the planet wheels 33, 34 will do likewise and both sun-wheels will be at rest. Any difference in speed will cause sun-wheel 31 to rotate and drive the output shaft 42 of the differential through step-up bevel gears 41, 44. A centrifugal governor 45 senses this speed and pushes a boss 48 downwards by an amount depending on the difference between the speeds of wheels 10, 11. Friction torque washers 52 cause this boss to turn in one direction or the other so that a finger 55 engages one or other of resistances 53, 54 to send current through lead 58 or 60 to an electromagnetic valve 18 or 19 which allows braking fluid to pass through an auxiliary pipe Y to brake the faster-rotating wheel. The amount of braking fluid passed depends on the difference between the speeds of the wheels, which determines the distance by which the finger 55 is pushed down the resistance. A changeover switch 59 is coupled to the gear selector so that the connections to the valves 18, 19 are interchanged when reverse gear is engaged. To ensure that the system operates only when starting the vehicle, further centrifugal governors 71, 72 open switches 61, 62 to disable the electrical connections when both wheels of the vehicle are turning at more than a predetermined speed. These governors are driven from the planet carriers 35, 36 through gears 67, 68 and 69, 70. The system may also be disabled when a higher gear than second is engaged, to prevent false operation at speed if one of the cables 26, 27 should break. The braking system may be hydraulic or pneumatic, and the brakes may be disc, drum or multiplate.

Abstract: 1,132,601. Multiple fastenings; sliding bolts. HICKMAN Ltd. 1 March, 1966 [2 March, 1965], No. 8795/65. Heading E2A. An actuating mechanism for a pair of contrasliding bolts comprises a housing, an actuating member 5 rotatable in the housing, two sliding members 2, 3 in the housing and drive transmitting means between the actuating member and the sliding members, in which a predetermined rotation of the actuating member 5 moves the sliding members 2, 3 away from each other in opposite directions through different distances relative to the housing. As shown, the sliding members 2, 3 are formed with toothed rack portions 10 and 13 which are engageable with pegs 6a, 6b of actuating member 5. The rack portion 13 comprises a central rigid tooth 14 and a pair of resilient teeth 15, 16 formed by the free ends of strips 17, 18 respectively riveted to the member 3. The arrangement is such that operation of the actuating member 5 effects greater movement of the member 2 than the member 3. The members are lockable in their projected positions by means of a barrel lock disposed in a cavity 7 Fig. 4 (not shown) in the base (1a) of the housing.

Abstract: 362,291. Steam-power plant. RUTHSACCUMULATOR AKTIEBOLAG, 1A, Eriksbergsgatan, Stockholm. March 21, 1931, No. 8801. Convention date, April 5, 1930. [Class 122 (iii).] In a stand-by steam-power plant an accumulator 1 is adapted initially to supply the live-steam turbine 4 as well as its own turbine 3, until steam is raised in a boiler 2 with small w a te r space. The turbines 3, 4 drive electric generators 5, 6 which work as synchronous motors and supply mains 7. A pipe 11 with a non-retum valve 10 is arranged between the accumulatorsteam pipe 9 and the live-steam pipe 8. A byepass 12 with a live-steam, pressure-controlled, overflow valve 13 bridges the valve 10. Upon failure of power, boiler 2 is heated, and the accumulator 1 supplies steam to turbine 3 and through the pipe 11 to turbine 4. As soon as steam is raised in boiler 2 it takes part in the steam supply, the accumulator supplying only its own turbine 3. When the interruption is prolonged, a further boiler 14 is put into use and supplies the turbine 3 when the accumulator has reached its lowest working pressure. The surplus steam from the two boilers may charge the accumulator. The place of the live-steam engine and the -accumulator-steam engine may be taken by an engine with live-steam and accumulator-steam sections.
