Title: Reducing the tendency of urea prills and microprills to cake
Inventor: JAMES WILLIAM MARTIN
IPC: C05C9/00
Filed: 1965-05-25
Abstract: The tendency of urea prills or microprills to cake is reduced by heating the urea particles at a temperature and for a time sufficient to bring their mass temperature to 93-127 DEG  C. and to melt their exteriors only, cooling the treated particles to below 82 DEG  C., screening the cool particles to remove the fine and oversize particles and bagging the cool screened particles, the process being carried out under conditions such that the particles do not fuse into a mass. The urea prills suitably have an average particle diameter of 1400-2200 m  and the urea microprills an average particle diameter of 500-750 m .  The process may be effected in a conventional apparatus, either batchwise or continuously.

Title: Improvements in and relating to the protection of synchronous electric motors
IPC: H02H7/085
Filed: 1944-11-13
Abstract: 579,026. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., and LIDDIARD, H. W. C. Nov. 13, 1944, No. 22325. [Class 38 (v)] Protection of a synchronous motor SM against heavy circulating currents which flow when, due to the opening and automatic reclosure of one of the breakers CB1. &c. an out-of-phase condition is established between the restored supply volts and the voltage generated by the stillrunning motor, is effected by connecting in the motor excitation-circuit a high-speed, h.r.c. fuse F, which is ruptured by the compensating A.C. component superimposed on the normal D.C. exciting current, and opens the field circuit, the resulting increase in the motorreactance then limiting the circulating current to a non-dangerous value. To deal with moderate out-of-phase conditions, the breaker CB is tripped by a relay R sensitive only to the A.C. component in the excitation-circuit. A discharge circuit DR, prevents undue voltagerise on rupture of the fuse.

IPC: D01H5/22
Filed: 1924-09-22
Abstract: 244,821. Groves, W. W., (Duplex Yarn Co.). Sept. 22, 1924. Rollers and roller heads; roving and thread guides.-In a spinning and doubling machine means are provided for drawing a roving of long fibres and for simultaneously drawing a roving of short fibres, and the winding-on bobbin is so arranged that the rovings are first separately spun and then twisted together. The apparatus may be adapted to deal with rovings composed of fibres of equal length. The twist in the doubled yarn is in the same direction as that of the individual yarns, and both yarns a, b, Fig. 2, are traversed by the guide bar 62 so that the length of each that extends from the nip of the rollers 11, 12 to the guide eye 3, where their junction is effected, is alternately shortened and lengthened whereby hard and soft twisted sections are produced which are twisted together and form a doubled yarn of substantially uniform size. The arrangement shown in Fig. 2 is adapted for yarn a of long fibre material and yarn b of short fibre material, the draft being effected between the rollers 56, 12 and rollers 38<a>. 11, respectively, and the rollers 54, 40 acting as carrier rollers. The rollers 40, 54 are of smaller diameter than the corresponding bottom rollers, rollers 39, 55 of the same diameter as the bottom rollers being provided to prevent contact of the rollers 40, 54 with the bottom rollers and allow free passage of the yarns. Carrier rollers 21, 22, 31, 32, are provided, the latter pair being mounted in a frame 27 adjustable by means of a pinion 37 and rack 38. The bar 62 carries guides 68, Fig. 5, and is traversed by a cam 65 driven by worm gearing from the shaft of the lower back roller 60. The action of this traversing movement may be modified or suspended so as to control the spacing and extent of the hard and soft twisted sections. If the yarns are of material of the same fibre length, the rollers are arranged so that the draft is effected between the rollers 54, 11, and 56, 12 the rollers 38<a>, 40 both being arranged to act as carrier rollers.

[Also in Divisions B8 and G1] A control system for controlling the rotation of an elongated radiation emitting body for example a hot metal ingot 8, comprises means 7 for rotating the said body about a transverse axis, a plurality of radiation sensitive devices 10 which receive radiation from the body and extend along a line greater in length than the body lying parallel to the plane of rotation of the body, -a coincidence circuit which receives signals from the radiation sensitive devices and provides an output signal when signals are received from a predetermined number of them, to stop rotation. The ingot is rotated in a clockwise direction by conical rollers 7, and when it has been rotated to a position parallel with the axes of the rollers 7 both inner photodiodes and either of the outer diodes, where there are four receive infra-red radiation from it. The outer diodes are connected through an " OR " element 13, Fig. 3 (not shown), to an AND element 15 through one of three monostable trip stages 14, the other two trips 14 connecting the inner diodes to the " AND " element such that the " AND " element provides an output signal only when both inner diodes and either of the outer diodes receive radiation. The output signal is fed through an amplifier 16 to control elements 17 which interrupt the rotation of the rollers 7. The radiation sensitive devices are mounted on the inside of a rotating cylinder opposite an associated optical system and the angle of the axis of rotation is made adjustable to compensate for inertia effects. The arrangement is associated with a rolling apparatus in which the ingot is passed to and fro between rollers under the control of a pair of photoelectric devices.

Patent GB-817376-A (GB)
Title: Process and apparatus for determining the filtration characteristics of spinning solutions under operating conditions
IPC: B01D35/00
Filed: 1956-07-19
Abstract: <PICT:0817376/IV (a)/1> The filtration characteristics of spinning solutions are determined while spinning is in progress by a process wherein a main supply pipe delivering spinning solution to the spinnerets is provided with a by-pass pipe in parallel with it through which a predetermined amount of spinning solution is delivered by a spinning pump driven at a given speed for a predetermined relatively long period of time via a standard filtration characteristics measurement filter and back again into the main supply pipe, and, immediately prior to and immediately following the predetermined relatively long period of time, the volumes of spinning solution passing through the filter in predetermined relatively short periods of time at a constant predetermined pressure at the inlet side of the filter are observed by collecting them in a graduated glass measuring cylinder open to the atmosphere, the outlet side of the filter being at atmospheric pressure.  As shown in the drawing, a new standard filter element is fitted in a standard measuring filter 4 and spinning solution is delivered from the main supply pipe 1 through branch pipe 2, spinning pump 3, the filter 4, 3-way cock 7 and delivery pipe 8 into a waste container until the pipes and filter are purged of air.  The graduated glass cylinder 9 is then placed beneath the pipe 8 and at the same time, by means of the adjustable pressure relief valve 6, the pressure at the inlet side of the filter is adjusted to a constant value, e.g. 2 atm. measured at the pressure gauge 5.  After the expiry of a short observed time, e.g. 5 minutes, the 3-way cock 7 is turned to divert the spinning solution discharged from the filter from the delivery pipe 8 via a return pipe to the main supply pipe 1 and the pressure relief valve 6 is closed.  The spinning pump is thereby caused to by-pass a portion of the spinning solution through the filter for some specified number of hours after which the volume of solution passing through the filter in a short specified time at a specified pressure drop across the filter is determined as before. The decrease in the filtration rate after a known volume of spinning solution has been pumped through the filter for a specified number of hours of spinning can thus be measured and the filtration characteristics of the spinning solution under actual operational conditions over a considerable period of time thereby determined.

Abstract: 1472338 Exhaust gas recirculation FORD MOTOR CO Ltd 23 May 1975 [10 June 1974] 22629/75 Heading F1B [Also in Division G3] A combustion engine has a system which utilizes a sensor responsive to the partial pressure of oxygen to control the ratio of air to fuel supplied to the engine, an air intake conduit, means for mixing fuel with the air, an exhaust conduit and a third conduit inter-connecting the air intake and exhaust conduits and through which a portion of the exhaust gases is recirculated to the engine intake, the sensor being located for exposure to the gaseous medium in the third conduit to sense the partial pressure of oxygen in the gaseous medium and means for modifying the partial pressure of oxygen in the portion of the exhaust gases to produce a partial pressure of oxygen in the gaseous medium different from the partial pressure of oxygen in the exhaust gases flowing through the exhaust conduit. Conduit 24 inter-connects intake manifold 14 and exhaust manifold 16, entry to the conduit being restricted by an orifice in insert 30. Oxygen sensor 26 is downstream of air inlet 28, so that the sensor responds to the oxygen content of a mixture of exhaust gas and air. The sensor is zirconium dioxide, the output E.M.F. of which varies abruptly as the air/fuel mixture supplied to the engine varies around stoichiometric. Alternatively the sensor may be titanium dioxide, the resistance of which changes abruptly in similar circumstances. The effect of adding air to the exhaust gas in conduit 24 is to produce exhaust gases similar to those which would result if the engine were being supplied with the weaker mixture than is actually the case.
