Abstract: 578,921. Foundations. WILLIAMS, L. W. March 15, 1944, No. 4861. Convention date, March 10, 1943. [Class 20 (ii)] [Also in Group XXIV] A foundation for buildings and machines and particularly power hammers, is of laminated construction comprising a plurality of superimposed plates of tough ductile metal capable of absorbing heavy stresses without failure and of becoming more firmly united under such stresses, and means for securing such plates in superimposed relation and against relative slip. Mounted on the concrete main base 10 of a large power hammer is a sub-base 11 which may be laminated according to the invention, or a cast steel block of a thickness of the order of two and a half feet and secured by bolts 12 the anvil block 13 carries a block 14 with die 15. The super-structure 16 of the hammer is secured by bolts 17, 18, to the anvil block which is of laminated structure being built up of plates 19-22 the opposed surfaces of which are corrugated to produce interlocking. Relative movement of the plates longitudinally of the corrugations is prevented by vertical bolts of different lengths. Thus, a number of bolts 23 pass through holes in the six lowermost plates, the heads being inserted in recesses 24 in the top surface of the lowest plate, the upper ends of the shanks terminating short of the bottom surface of the next overlying plate. The bolts are a sliding fit in the holes. Similarly, bolts 25 prevent relative movement of the top seven plates and, at the same time, lock the upper set of plates to the lower plates. All the plates above the bottom plate 22 are locked together by bolts 27 the heads of which bear against springs 32 in recesses 28 in the lower plate 21, the upper ends of the shanks having nuts in recesses 29 in the block 14. The anvil block is secured to the subbase 11 and main base 10 by bolts 30. Compression springs 35 are placed under the nuts 36 which secure the super-structure 16 to the block. Groups of plates may be welded together by seams at the ends. The plates 20, 21, 22 are made from a tough, ductile steel or alloy ferrous or non-ferrous; the top plate 19 may also be of the same material but is preferably a heat-treated alloy steel having greater hardness and toughness. The plates may be heat-treated. Sheets of soft material, e.g., lead, bronze, or wood may be placed between the corrugated steel plates and sealed by the welds referred to above. Instead of the plates being corrugated, they may be flat and formed with projecting members and corresponding recesses.

Abstract: 1304281 Traversing arrangements MONSANTO CO 2 Feb 1970 [10 Feb 1969] 4875/70 Heading D1J Yarn 28 is traversed onto a bobbin 24 by a guide 16 following a groove 8 in driven drum 4, and may pass around a driving roller 20 onto the bobbin. Near the ends of the traverse, the yarn is engaged by pins 38, 40 on rotating discs 30, 32, which carry it outside its normal traverse path, reducing the effects of reversal curves in the groove 8, and progressively shorten the yarn trial length, thus avoiding excessive build-up of windings at the package ends. The discs are mounted symmetrically at angles to the plane in which the yarn travels, and are driven so that the pins move faster than the traverse guide 16. The resultant winding pattern (developed in Fig. 13) is substantially helical, the slight reversal curves 48 being offset to occur prior to the point of reversal.

Abstract: 707,690. Pneumatic conveyers. DORR CO., Feb. 27, 1952 [May 21, 1951], No. 5125/52. Class 78 (1) In apparatus for controlling the flow of finely divided material comprising a container having an outlet member extending laterally of it, the. outlet member is sufficiently long to support a layer of the material in a state of repose and feeding of the material from the layer is effected by disturbing the normal condition of repose by injecting a stream of gas into the mass of material in the container at a point above the level of the outlet. Material 19 in the vessel 11 rests on a plate 17 provided with passages 18 through which passes fluidizing air supplied by the pipe 22. Material enters the vessel through the pipe 30 and fuel is supplied by the pipe 23. Fuel for starting up is supplied to a burner (not shown) through the pipe 24. Gases leave the vessel through the Pipe 25 and enter a dust' separator 45. The separated solids fall into a vertical pipe 137 having an elbow 138 connecting it to a discharge pipe 130. The elbow is of such length that normally the solids will not pass through it but will take up a position of repose in which the inclined edge of the end of the material is to the right of the pipe 130. When gas is supplied through the pipe 139, the solids will be disturbed and will flow through the elbow into the pipe 130. Solids from the bed 19 are discharged through a vertical pipe 237, horizontal pipe 238 and an inclined pipe 230 when gas is admitted through the pipe 239, the solids normally remaining in a non-flowing angle of repose in the pipe 238. Solids may be removed through a pipe 347 and transported by a gas stream to heat exchange or other processing apparatus. The pipe 347 opens into a vertical chamber 337 which has lateral outlets 342..345 leading into a pipe 350 to which gas is admitted through the valve 351. The material reposes in the outlet as it does in the elbow 138 and is discharged when gas is admitted to the chamber from the pipe 339 at points opposite to each outlet. The supply of gas is controlled by a master valve 339a and valves 339b at each inlet.

An electric motor as described in the parent Specification having a polyphase excited stator I and a rotor II carrying an intermittently excited winding, is modified in that the rotor winding is intermittently short-circuited by a contact drum 9, the periods of short-circuit being altered to control the speed. The control drum is continuously rotated and, in the form shown in Fig. 1, has tapered contacts 10 engaged by a brush 11 which is slidable along the drum by means of a hand wheel 5 to control the length of the periods during which the rotor winding is short-circuited. If desired a rectifier may be included in rotor circuit to provide unidirectional current pulses. Two machines may be coupled together on the same shaft with their stators connected for reverse phase rotation to provide rotation in either direction depending on which rotor is connected to the drum. If one of the stators is D.C. excited braking may be achieved, or alternatively a single rotor may have longitudinal recesses cut in its surface to produce the same effect. A modified control drum is shown in Fig. 7, in which a conducting segment 79 fixed to an insulating wheel 78 serves to bridge contacts 80, 81 for a period which is adjustable depending on the adjusted position of one of the contacts 81. A system is described in which the speed is regulated by a tachometer which can insert resistance in the rotor circuit to reduce the speed, and connect alternative brushes axially displaced on the control drum to give longer periods of connection to increase the speed. Mechanical means for controlling the speed are described.

Abstract: 525,182. Directive wireless systems. STANDARD TELEPHONES & CABLES, Ltd., and EARP, C. W. Feb. 17, 1939, No. 5324. [Class 40 (v)] The angular bearing (or elevation) of a moving craft relatively to a distant transmitter is obtained by comparing the signals from two overlapping beams, differently modulated, with signals containing the same modulation frequencies on a different carrier and transmitted simultaneously from a non-directional aerial. In Fig. 1, two portions of the output from the carrier wave generator C1 are separately modulated in the balanced modulators M1, M2 with different frequencies fl(t), f2(t) generated by the oscillators O1 and O2, the modulation products being fed to the crossed loops L1, L2 respectively. A non-directional comparison signal comprising a carrier of different frequency generated at C2 and modulated at M3 with both of the frequencies fl(t), f2(t) is radiated from the open aerial VI and if the overlapping characteristics are to be of the cardioid form another portion of the output from the generator C1 is also radiated from the aerial VI. At the receiver, the signals of carrier frequency C1 are amplified at A1, Fig. 2, and after detection at D1 a low-frequency signal of the form sin f1t cos # + sin f2t cos (#+90), where # is the bearing of the receiver from the loop L1, is applied to the movable coil S of a dynamometer B. Meanwhile the signal of carrier frequency C2 is amplified at A2 and after detection at D2 the two modulation frequencies fl, f2 are separated by the filters F1, F2 and applied to the field-coils X, Y. The resultant deflection of the coil S then indicates the bearing angle #. Alternatively, the connections from the detectors D1, D2 to the dynamometer may be reversed. Or a cathode-ray indicator ,can be used as described in Specification 490,940, in which case the two modulation frequencies derived from the non-directional signal are applied to the deflection plates, and the modulation components obtained from the directional signals are used to control the intensity of the electron beam. Modulating wave forms other than sinusoidal may be employed.
