Abstract: 555,010. Granular coated webs. ABBEY, A. (Carborundum Co.). Jan. 27, 1942, No. 1159. [Class 60] In the manufacture of abrasive coated webs the web 1 between the application of adhesive by the roller 5 and the application of abrasive from the hopper 30 passes through a conditioning chamber 49 to prevent any change in the consistency of the adhesive on the way, the atmosphere of which chamber is kept in a calm or quiescent condition at a suitable temperature by means of the control elements 11 and heating elements 10 and in a proper condition of solvent humidity by means of solvent reservoirs 13, 13a provided with control elements 15 and heating elements 14, the roof of the chamber being maintained at a temperature above solvent condensation point and moved transversely to prevent any droplets forming thereon from falling on the adhesively coated web. After leaving the chamber 49 the web passes through an enclosed electrostatic granule applying unit 55 and then through a second conditioning chamber 56 comprising solvent reservoirs 44, heating elements 45 and control elements 46 whereby the surface tension of the adhesive is reduced enabling it to wet the sides of the abrasives grains so that the latter penetrate farther into the adhesive coating and become more firmly anchored.

Title: Improvements in or relating to carburettors
IPC: F02M7/11
Filed: 1923-01-16
Abstract: 214,322. Modesse, A. Jan. 16, 1923. Spray carburettors.-Fuel from a flcat chamber 4, Fig. 2 passes to a well 20 whence it is drawn into the induction pipe 14 through a pipe 5, the spaces above the fuel in the float chamber and well, communicating through pipes 12, 13 respectively with Venturi passages 1, 1'. These passages may have extra air inlet branches 8, 7 provided with valves 30, 29. The Venturi into which the pipe 5 delivers may open into another Venturi. The Venturi passages produce at the surfaces of the fuel in the float chamber and well, opposed negative pressures of substantially equal value. In the modification shown in Fig. 3, the pipe 5 dips into the well 20 to below the lowest level therein, and a pipe 26 dipping just below the highest level discharges into a chamber 25 from which two pipes 23, 24 lead to points on the engine and air inlet slides respectivelv of the throttle valve when in the closed position A. The Venturi passages 1 may have a valve 21. With the throttle in closed position A, fuel is delivered by pipe 23 mixed with air through pipe 24. In the position B of the throttle, both pipes 23, 24 deliver fuel. In position C of the throttle the lower end of pipe 26 is uncovered and the fuel is supplied only through the pipe 5. With a sudden increase of suction all three pipes may supply fuel. In a still further modification, the inlets to the Venturi passages 1, 1<1> are closed by a spring- loaded valve, which has the effect of increasing the suction to such an extent that the negative pressure in the float chamber is sufficient to raise fluid thereto from a low level tank.

Abstract: 104,518. McColl, A. E. Feb. 2, 1916. Protective a r - rangements. - The sub-station ends z of parallel feeders or circuits in an alternating current single or three phase system are protected against the return flow of current from other feeders, circuits, or interconnectors in the event of a defect in the parallel feeders &c., by reverse current relays one element R of each of which is retained at relatively constant polarity by one or more pilot wires W carrying the sum of the currents from the secondaries of series transformers T1, T2, T3 connected in parallel, the primary of each of the transformers being connected in circuit with one of the feeders &c. at the end adjacent to the source of supply. In the case of a single-phase system, one pilot wire with ground returns may be used. The feeders are protected at the source ends by discriminating-relays D, which may be operated by the transformers T1, T2, T3 or by separate transformers. To protect the last of the parallel feeders from return flow from associated interconnectors I, Fig. 4, in the event of the circuitbreaker at the source end opening, on fault development, before the reverse current relay operates, transformers T16 located in the interconnectors and connected in parallel with one another supply current to the field wire system W. The transformers T16 are of less capacity than the transformers TF at the source end of the feeders, and they may be replaced by a single transformer in the bus-bar between the feeders and the interconnectors. In a modification, the reverse current relays each have three elements, one of which, the restraining-element, is energized from the pilot wire or wires W.

Title: Improvements relating to the correction of magnetic compasses
Inventor: HARVEY GILBERT NATHANIEL
IPC: G01C17/38
Filed: 1959-01-16
Abstract: 872,096. Magnetic compass correction. MINISTER OF AVIATION. Jan. 13, 1960 [Jan. 16, 1959], No. 1768/59. Class 40 (1). The magnetic compass system of Specification 775,440, wherein two magnetic detectors are located at different points on an aircraft or other vehicle and the output of one used to correct the other for errors due to the proximity of the structure of the vehicle, is modified by feeding the outputs of the two detectors to the same synchro stator; the signal from the synchro rotor is passed via a phase-sensitive circuit to a servomotor which turns the rotor until the input to the motor is zero; the output of one detector is made adjustable in phase or amplitude relative to the other to achieve the desired correction so that the final angular position of the synchro rotor will indicate the corrected bearing of the vehicle. In the Figure the two detectors 1 and 2 are of the flux-gate type, and are mounted in pendulous holders on a projecting boom so that the former is further away from the body of the vehicle than the latter. The energizing coils 3 and 4 are supplied with current at 400 c/s. with a phase difference depending on the setting of a phase-shifter 17. The signals induced in the detectors by the magnetic field of the vehicle will be different in amplitude and it can be shown that for a given setting of the phase-shifter the output from the synchro rotor 12 will be independent of the contribution from this field. The output is compared with the doubled supply frequency in a phase-sensitive rectifier 19 and any difference is passed to a servomotor 24 which turns the rotor until the difference signal is zero. The unit 17 may introduce a fixed phase-shift, e.g. 45 degrees, and a variable phase-shifter is then included in the lead to the frequency doubler. The outputs of the detectors can be made to differ in amplitude instead of phase by winding the corrector unit 2 with fewer turns or by including resistances in the leads from this unit to the synchro stator. Final adjustment can be made with a three-gang variable resistor in series with the unit. The detector units may have two arms instead of three, with appropriate modification of the synchro. According to the Provisional Specification the adjustment can be carried out by a resistor across the synchro rotor.

Title: Improvements in or relating to the connecting of metallic members by screwed joints
IPC: F16B25/00
Filed: 1933-01-19
Abstract: 413,027. B o l tin g. DARDELET, H. L., 5, Rue Menou, Nantes, Loire-Inf�rieure, France. Jan. 19, 1933, No. 1824. [Class 89 (i).] Relates to a method of making screwed joints such as by securing parts together by studs or bolts in which a screw-threaded member is screwed into or on to an unthreaded member of softer material in which threads are cut as the joint is made. The engaging surface of one member is cylindrical and that of the other is partly cylindrical and partly conical, and the dimensions are such that the thread of the harder member is not completely filled by the material displaced in cutting the thread on the softer member. For example, in the case of a screw c<2>, Fig. 7, and an unthreaded nut a of softer metal the bore d is greater than the mean of the diameters e, f, of the top and bottom of the threads of the screw. The conical portion a<2> of the bore facilitates the commencement of the operation. The head of a bolt may be secured to a shank by the above method. In bolting together two plates A, B, Fig. 11, screw threads are formed in the holes in the plate as well as in the nut o. The nut may engage a portion of the bolt smaller in diameter than the holes in the plate. The shank of the bolt adjacent the head is reduced in diameter over a length k greater than the thickness of plate B. The end of a stud bolt has a groove v<2>, Fig. 15, extending along a part of the tapered threaded portion to facilitate the cutting of the thread.
