Title: Improvements in rotary cell-wheel feeders
Inventor: ALLEN ROBERT WILLIAM
IPC: B65G53/46
Filed: 1962-04-24
Abstract: 963,045. Pneumatic conveyers. HENRY SIMON Ltd. April 16, 1963 [April 24, 1962], No. 15488/62. Heading B8A. In a rotary feeder for delivering pulverulent material to a pneumatic conveyer system, comprising a rotor element within a cylindrical casing 1 having end walls, the rotor element comprises pockets 10 formed by vanes 9 which are substantially tangential to the rotor hub 8 and twisted helically relative to the axis of the rotor, and are forwardly curved in the direction of rotation. The rotor element is mounted on a shaft 5 which is journalled in bearings in the end walls of the casing 1. The vanes 9 are of a cross-sectional profile such that at the operational speed of the rotor, a particle 14 delivered under gravity through an opening 11 in the top of the casing 1, will continue its vertical path 16 while still in contact with either the leading, 15, or trailing face, 17, of the vane. The helical twist of the vanes is such that at the operational speed of the rotor, the outlet ends of the pockets trail behind the air inlet ends of the pockets by an amount which will ensure that the air of the conveyer system passing from an inlet to an outlet port 13 in opposite end walls of the casing 1 will travel along a substantially straight path whilst scavenging the pockets 10.

Title: Improvements in and relating to electric generator control systems
IPC: H02P9/00
Filed: 1929-05-17
Abstract: 333,618. British Thomson-Houston Co., Ltd., and Harris, F. H. May 17, 1929. Dynamos and motors combined for transmitting power; regulation, automatic.-The terminal voltage of a separately-excited generator is automatically maintained constant under speed variation. The output of a constant speed exciter is controlled by a device operated by the current from an auxiliary generator having a voltage-field current characteristic similar to the main generator and sharing its speed variation and being excited from the same source. In a Ward Leonard system for driving a rolling-mill motor the main generator 14 is excited from a constant speed exciter 23. An exciter 29 furnishes the excitation of the generator exciter 23 and of the motor exciter 31. The field strength of the last is controlled by a vibrating regulator 35 energized by the current from an auxiliary generator 33 on the main generator shaft, which is excited in parallel with the main generator. The speed control switches 46 - - 48 are coupled to switches controlling resistances 37 - - 39 in the circuit of the regulator winding so that the relay remains balanced whatever the position of the speed control mechanism. The auxiliary generator 33 may be arranged to work at a point on its saturation curve sufficiently above the point at which the main generator 14 works to compensate for the voltage drop due to the internal resistance of the latter generator.

Filed: 1967-04-05
Abstract: 1,171,227. Reciprocating pumps. YALE & TOWNE G.m.b.H. April 5, 1967 [May 3, 1966], No. 15682/67. Heading F1A. [Also in Division F2] Hydrostatic transmission for an engine-driven vehicle, e.g. a fork lift truck, has a variable stroke pump and a fixed stroke motor, a pump stroke control linkage being connected to the engine accelerator pedal so that the pump stroke is increased as engine speed is increased, and a piston and cylinder device 12, 11 in the linkage being responsive to pump output pressure to reduce the pump stroke independently of accelerator position as said pressure increases. The tilt angle of the pump swash-plate is adjusted by rotation of a shaft 4 to which is secured a lever 17. Links 18, 19 pivoted to opposite ends of the lever 17 have slots 20 at their other ends engaged by a pin 21 on a bell-crank 9 in the engine accelerator control linkage. The piston rod of piston 11 is pivoted to the pin 21 and carries a pin 26 which engages a forked end of a lever 25 pivoted about the shaft 4. Recesses 23 in a flange on the cylinder 12 are respectively engageable with a dog 22 on link 18 for forward drive and a dog 22 on link 19 for reverse drive, under the control of a "Forward-Neutral-Reverse" selector (not shown) which pivots the lever 25 up or down from the central neutral position shown. Pump outlet pressure is communicated to the cylinder 12, via a flexible pipe 16 and a bore in the piston extension 13, to oppose the action of a spring 15 abutting the cylinder flange and a flange 14 on the extension 13. With the cylinder flange engaging one of the dogs 22, movement of bell-crank 9 is transmitted via piston 11, spring 15, and cylinder flange, to link 18 or 19 to rotate the shaft 4. When the pump outlet pressure acting in the cylinder 12 overcomes the spring 15, the cylinder is moved leftwards, allowing the swash-plate angle to decrease.

Title: Treating wool and other animal fibres to reduce tendency to felting and shrinkage
IPC: D06M11/30
Filed: 1942-11-13
Abstract: Wool or other animal fibres are given diminished felting properties by treating them with an aqueous solution of a water-soluble chlorite and a mineral acid.  The wool may be in the form of loose fibres, tops, yarn, knitted or woven fabrics, or garments, in the oiled, scoured, or dyed state.  In order to obviate discolouration of the materials treated, a substance capable of reacting with chlorine peroxide, e.g. hydrogen peroxide, oxalic acid, tartaric acid, or a mixture of these substances, may be included in the aqueous solution. Sodium, potassium or calcium chlorite may be used and the acid may be hydrochloric or sulphuric acid.  Wool materials may be first impregnated with an aqueous solution of the chlorite containing a wetting agent such as sulphonated oleic acid, the sodium salt of sulphated sperm oil alcohols, or a condensation product of cetyl alcohol with ethylene oxide.  The chlorite solution may be at a temperature up to about 50 DEG  C.  The impregnated materials are immersed in a hot solution of the mineral acid.  The reaction may be stopped by immersing the materials in a solution of sodium sulphite, bisulphite, hydrosulphite, or formaldehyde-sulphoxylate.  The tensile strength, elasticity and durability of wool materials are not sensibly impaired by the treatment.

Abstract: 161,196. Maison Breguet, and Routin, J. L. July 5, 1917, [Convention date]. Addition to 127,280. Sights and methods of sighting.-Relates to the anti-aircraft gunnery apparatus described in the parent Specification, and consists in apparatus for obtaining the fuze time and the product of the time of flight and the angular speed of the target, in the case where the target is flying at a constant height. In the apparatus shown, the drum 1 is rotated by an amount proportional to a function of the height H0 of the target, and the drum 21 by an amount proportional to a function of the time of flight f0 of the projectile. On the drum 1 are drawn two series of curves representing the time of flight f0 and the range D respectively. These are read against two indexes 12, 13 carried by bands 10, 11 each connected at one end to a spring drum 14, 15 and at the other end to a sector 9 carried by the sighting-telescope for elevation. The lower band 11 passes over a pulley 19 which is displaced to give the extrapolated range by means of a hand-wheel 16 and screwed spindle 18, the correct displacement being indicated by a pointer 20, rigidly connected to the pulley 19, which is adjusted on a curve of a function of the sighting correction # on the second drum 21. On the left-hand part of the drum 21 are traced curves graduated in functions of the sighting corrections o- and #. These are read by two indexes 32, 33 carried by bands 30, 31, which are connected at one end to spring drums 34, 35 respectively for keeping them under tension, and at the other end to drums 28, 29 connected to speed indicators giving the azimuthal and zenithal components of the angular speed of the target, thus a direct reading is obtained of the product of the angular speed and the time of flight of the projectile.

Title: Multiplex audio response unit
IPC: G10L19/02
Filed: 1971-05-21
Abstract: 1337471 Speech synthesis INTERNATIONAL BUSINESS MACHINES CORP 21 May 1971 [1 Sept 1970] 16207/71 Heading H4R In a speech synthesizer audio signals, stored in coded data form in a store 11, are applied to a speech synthesizer 19, e.g. of vocoder type, which synthesizes speech in time compressed form. The compressed signals, after being converted to digital form in a to d converter 20 are fed to the respective channels a, b, ... 1 where they are fed to time expanding circuits from which they are read out at lower speed to provide audio signals in the channels La, Lb, ... L1. As described audio signals are stored in a form suitable for use in a base band vocoder, i.e. as information specifying the waveform of a low frequency band of the speech together with information specifying the energy level in a number of frequency bands of the remainder of the speech band. Base band information is stored as 6 bit logarithmic coding of samples of the base band, taken at 1200 Hz, 24 successive samples of the base band being associated with each sample of the spectrum function, which is coded as 4 binary digits for each of 12 channels, the sampling rate being 50 Hz. Information is read out of a direct access memory 11, alternately into stores 12 and 13 which are read out alternately, one store being read out as the other is filled, into a synthesizer 19. In the synthesizer the spectrum function and excitation function signals are converted into analogue form, multiplied together, after appropriate filtering and shaping, and the various channel signals added together to provide audio signals. The extraction of information and the synthesis is performed in time division multiplex for a number of output channels and the speech is in time compressed form, the compression applied being greater than that required purely for the multiplexing to allow repetition and discarding of portions of the synthesizer output at the beginning and end of each t d m channel signal sample to eliminate inaccuracies due to setting up and decay transient phenomena of the synthesizer filters. In order to expand the speech and distribute it to the appropriate channels La, Lb, ... L1 the output from the synthesizer is converted to digital form in a to d converter 20 and the signals distributed by appropriate operation of the gates a, b, c, etc. Time expansion is effected by feeding the signals in each channel into a recirculating delay line La, Lb, etc., from which the signals are read out at reduced rate to provide, after treatment in d to a converters Ca, Cb, etc., and low pass filtering in filters Fa, Fb, etc., the audio channel signals. Described with respect to Figs. 7 to 10 (not shown) is the manner in which the serial binary stream from the store 11 is converted into parallel form to feed into registers holding the spectrum function and excitation function signals in the vocoder type synthesizer 19.
