Patent GB-287748-A (GB)
Abstract: 287,748. Le Tall, F. W., (Westinghouse Electric & Manufacturing Co.). June 7, 1927. Firebars; grates.-A furnace grate for use with a mechanical stoker having a longitudinal retort 10 with fuel-feeding mechanism adapted to discharge fuel to laterally extending grates comprises series of grate members 36 - - 39 pivotally coupled together end to end by hinge pins 42, - 44 each series being pivotally supported at the end adjacent the retort and slidably supported at the other end, and actuating means 47, 58 operated by the fuel feeding mechanism for imparting hinging motions to adjacent members of the series. Fuel is fed from a hopper 11 to the retort 10 by rams 13, 14 driven by an engine 12 and passes over the lateral grate sections to dumping grates 17. The inner grate members 36 are pivoted to the sides of the retort while the outer grate members 39 are slidable on supports 56, which may be hollowed out to oscillate the members 39 as they slide. Lugs 46 depend from the grate members 37 and engage links 47 driven by cranks 48 from shafts 49 extending beneath the grate and oscillated by the engine 12. Between the hinge pins 42, 44 is arranged a tilting support 58 upon which the intermediate grate members slide. For the admission of air to the fuel the grate members are provided with lateral recesses 40 and fluted portions 45 which are progressively increased in number from the outer to the inner grate members. Air is supplied to the space beneath the grate by a conduit 31 and an auxiliary air supply 60 is arranged above the grate. Air ports 57 are provided in the supports 56. The dumping grates 17 are supported on shafts 61 and held in the raised position by a catch which is disengaged to allow the grate to fall by gravity, fluid-pressure means 94 being pro. vided for raising the grate. The grate members are pressed together by an angle member 66 acted on by a bell-crank lever having a weight suspended from its free arm. Fig. 5 shows the driving mechanism of the grate, the piston rod 73 of the stoker engine cylinder 71 which drives the rams 13, 14 carrying a clamp 76 to which is pivoted a slotted lever 77 connected by a link 78 to a fixed shaft 79. Journaled on the shaft 79 is a bevel gear 81 meshing with a bevel gear 82 on the grate-operating shaft 49 and having an arm 83 connected by a link 84 to a pin 86 movable within the slot 87 in the lever 77. By varying the position of the pin 86 in the slot by means of a screw 88 with a hand-wheel 89 the oscillatory motion imparted to the shaft 49 may be varied. In a modification the outer grate member of each series is connected to a fixed support by a link and the intermediate grate members are connected by links to a rocking bar fixed to the shaft 49.

Title: Improvements in stop-on-signal radio apparatus
IPC: H03J7/30
Filed: 1947-10-28
Abstract: 649,536. Automatic tuning control. ANDREWS, E. F. Oct. 28, 1947, No. 28804. Convention date, Nov. 1, 1946. [Class 40 (v)] Radio apparatus is provided with resilient power storage means for driving the tuning means through the normal tuning range, and means for automatically stopping the variation in tuning in response to a received signal. The tuning cores 52 of a superheterodyne receiver are arranged to be moved to the low-frequency end of the range as shown by a solenoid 64 acting through a lever arm 70, roller 72 and yoke 54. This movement charges a spring 60 which then moves the cores back through the tuning range under the retarding action of lever 68 and gear train 98 ending in a wind wave 82. If during this tuning movement a signal is tuned in, gas relay tube 112 is ionized by a control voltage produced in the manner described in Specification 633,397. This allows condenser 174 to discharge through conductor 184 to energize a bucking winding 176 of relay 110 to release armature 206 which is moved by a spring 244 to apply a brake to the gear train 98 and arrest the tuning. Movement of armature 206 connects condenser 220 to ground through contact 222, thus changing the A.V.C. circuit from fastacting to slow-acting for normal reception. Also a muting connection from the audio stage is broken at contact 228. The hold-on circuit for relay 110 is broken at contact 216, and at contact 236 is broken the earth connection of a limit switch 200. This switch is operated by a yoke 250 at each end of the travel of solenoid 64 and lever 68 to cause successive energization of the solenoid if no signal is encountered, and also to ensure that the tuning is not arrested during the rapid downward movement of the tuning cores under the control of the solenoid. The tuning operation is started by a switch 202 which operates relay 110 by winding 204 and completes a hold-on circuit at 216, and removes the brake from the gear train 98, thus allowing automatic tuning to proceed. The wind vane has a one-way driving connection to the gear train and can thus over-run when the gear train is braked. When the set has been tuned to a signal no current is consumed as the parts are held in the tuned position by brake spring 244. The wind vane may be replaced by a centrifugal brake. Specification 649,537 and U.S.A. Specifications 2,262,218 and 2,326,738 also are referred to.

Title: Gapped Deconvolution Filtering for Suppressing Reverberations in Electrical Seismic Traces
IPC: G01V1/38
Filed: 1967-06-22
Abstract: 1,195,263. Seismic prospecting. TEXAS INSTRUMENTS Inc. 22 June, 1967 [23 June, 1966], No. 28808/67. Heading H4D. Reverberations in a seismic trace are suppressed by deriving the auto-correlation function X of a limited time-gate of the trace, deriving the cross-correlation function Z of the said time-gate with the same time-gate of the trace delayed by a time T substantially equal to the two-way travel time of seismic energy reflected from the subsurface horizon giving rise to the reverberations, time-domain filtering the trace with a filter function Y obtained from the matrix equation XY = Z, delaying the filtered trace by the time T and subtracting the delayed filtered trace from the original undelayed trace. In the Fig. 1 embodiment, analogue processing of the trace from geophone 11 of an array is considered; similar processing is applied to traces from the other geophones. The trace is recorded as traces 36, 36<SP>1</SP> on magnetic drums 31 to 34, the traces 36<SP>1</SP> being delayed by time T (the travel time in water layer 12) relative to trace 36, and the recorded traces are then reproduced repetitively while stepping devices 83, 84 apply incremental time-shifts T between the drums. The reproduced signals pass to multiplier-integrators 45, 48 which develop respectively the cross-correlation function Z and autocorrelation function X of a time gate of the signals. Programmed potentiometers 85-87 provide a smooth initiation and termination of the time gate. The correlation functions are stored on drum 47. The original trace from geophone 11 is filtered by a seven-point time-domain filter comprising drum 34, delay outputs 61- 67, weighting resistors (or variable-gain amplifiers) 68-74 and adder 75. Drum 34 provides a delay of T Œ nr (n = - 3 to + 3) on outputs 61-67, and the sum of the delayed output signals is subtracted from the original (undelayed) trace in adder 75 to give a reverberation-free trace which is applied to storage unit 81 and recorder 82. Weighting factors for the filter are determined by computer 60 which derives the filter function Y by solving the matrix equation [Y] = [X]-<SP>1</SP>[Z]. Spread corrections may be applied to the geophone traces before the above processing, and the processing may be done digitally instead of by the analogue, Fig. 1, system. Time-domain filters longer than seven points may be used.

Filed: 1949-11-10
Abstract: 670,820. Toothed gearing. SHEPHERD, G. R. (Westinghouse Electric International Co.). Nov. 10, 1949, No. 28816/49, Class 80 (i). [Also in Group VIII] Laminated blanks for rim members for gears or wheels are made from a strip 10 of fibrous material which is impregnated with a resinous binder and provided with discontinuous spaced aligned slits along its centre line. The strip is softened by superheated steam ejected through perforations in platens 26 and 28, is folded along its centre line about the aligned slits, e.g. by folding-rollers 30 and 32, and is wound on edge on a mandrel 20 in the shape of a helix having the aligned slits in the outer edge while pressure is applied to the turns, e.g. by a roller 24. A thin dressing of a lubricating or waxy material such as calcium stearate may be applied to the strip, e.g. by rubbing contact with a block 34 of the material, to facilitate folding and winding. The fibrous strip may be a woven fabric and the resinous impregnant a phenol- or urea-formaldehyde resin. On cooling, the helix is removed from the mandrel in the form of a cylinder which, while placed on a second support is cut into equal-sized sections by means of a cutting tool which severs only one turn of the helix. The sections are thereafter hot-pressed into consolidated rim members embodied in a gear or wheel.

Title: Automatic wear adjustment means for brakes
IPC: F16D65/54
Filed: 1953-10-23
Abstract: 738,247. Helical springs. WINGFOOT CORPORATION. Oct. 23, 1953 [March 27, 1953], No. 29312/53. Class 108 (3). [Also in Group XXXIV] In a brake assembly provision is made for the automatic adjustment for wear occurring in the movable friction lining brake block by the fitting of a return compression spring which is capable of assuming, in use, a plurality of progressively shorter lengths as it is stressed beyond its yield point in consequence of wearing down of the brake block, so as to retract the latter through a distance approximately independent of such wearing down. In the " spot-type " disc brake assembly illustrated in Fig. 1, a brake housing 2 is secured to a stationary axle 3 and carries a fluid pressure piston and cylinder mechanism 10 to frictionally engage a brake block 13 with a side surface of a brake disc 6, which is rotatable with and axially slidable on a vehicle wheel 4, to move the disc 6 axially into frictional contact with a fixed brake block 12. The return compression spring 18, shown diagrammatically in Fig. 2, in exaggerated form, may be of a low carbon steel (about 0.05 per cent carbon) are fitted to the brake assembly as shown in Fig. 1. Fig. 2 illustrates the initial length, its length when loaded, its initial yield point and the slight return from the yield point (i.e. the recovery). The recovery provides the necessary small clearance, when the brake is released, to bring the brake block 13 out of contact with the brake disc 6. It is stated that in operation the spring would have an almost infinite number of new released lengths as it would take a new permanent set every time an infinitesimal layer of brake lining is worn off and that when the brake blocks 12 and 13 are replaced, when worn, the spring 18 may be stretched out to substantially its original length ready for a second operative cycle.

Title: Improvements in and relating to production of halogen substituted phosphines
Inventor: HOFMANN EUGEN
IPC: C07F9/52
Filed: 1959-08-28
Abstract: Mono-halogen substituted phosphines are obtained by reacting a carbonyl halide, preferably phosgene, with a compound of formula R1R2PH in which R1 and R2 are the same or different unsubstituted or substituted hydrocarbon groups.  When the compound R1R2PH is a liquid the process may be carried out by passing the carbonyl halide into the liquid compound.  When the compound R1R2PH is a solid an inert solvent for both reactants is used, suitable solvents being hydrocarbons and ethers.  A suitable method comprises dissolving the carbonyl halide in the solvent and then contacting the solution with the compound R1R2PH which may also be in solution.  Alternatively, the carbonyl halide may be passed in the gaseous state into a solution of the phosphorus compound.  The reaction may be carried out at any temperature up to the boiling point of the mixture.  Examples are given for the production of diphenyl- and diethyl - monochloro - phosphines respectively.  The products are useful as intermediates in the production of phosphorus-containing polymers.  Diphenylphosphine may be obtained by reacting triphenyl phosphine with an alkali metal, e.g. Li or K, in a solvent such as tetrahydrofuran or dioxane, and then hydrolysing the phospho-alkali metal compound formed.
