Title: Improvements in or relating to centrifugal separators
IPC: B01D21/00
Filed: 1948-04-19
Abstract: The temperature of the liquid in the bowl of a centrifugal clarifier is controlled by circulating air or gas therearound from the bowl axis towards its periphery, and thence through a heater or cooler, and back to the bowl axis.  The casing surrounding the bowl is stationary and has a drain pipe for waste liquid provided with a liquid trap to prevent loss of the gas.  The Specification as open to inspection under Sect. 91 states that the temperature of the liquid in the bowl may be controlled by spraying gas or liquid on to the bowl.  Alternatively, to prevent heat transfer through the bowl, the bowl is coated with heat insulating material.  Insulating material may also be placed between a rustless steel lining and the shell of the bowl.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the fireproofing of fibrous materials
Inventor: VALLETTE PIERRE HENRI PAUL
IPC: D06M15/673
Filed: 1954-04-15
Abstract: Phosphonitrile chloride may be prepared by the action of ammonium chloride on phosphorus pentachloride, in the presence if desired of an inert organic solvent, at a temperature of about 140 DEG C. Specified solvents are carbon tetra-chloride, tetrachlorethane, chlorobenzene and orthodichlorobenzene.  The reaction may be represented as proceeding thus:- nPCl5 + nNH4Cl-->(PNCl2)n + 4nHCl. Phosphonitrile chloride may be treated with dry ammonia the reaction being carried out, if desired in the presence of an inert organic solvent (as above).  There is obtained in the course of this reaction hydrogen-amine compounds such as (P3N3Cl5NH2)n and (P3N3Cl4(NH2)2)n or aminated compounds such as (PN(NH2)2)n in accordance with the reaction:- (PNCl2)n + 4nNH3-->(PN (NH2)2)n + 2nNH4Cl.  Examples describe the preparation of phosphonitrile chloride by heating together phosphorus pentachloride and ammonium chloride or by refluxing them in the presence of an inert organic solvent (as above).  The phosphonitrile chloride is then treated with ammonia by bubbling the dry gas through a solution of it in an inert organic solvent as by putting it into suspension in liquid ammonia at -45 DEG C.

Title: Improvements in or relating to fertilizer distributing machines
IPC: A01C15/18
Filed: 1943-07-12
Abstract: 566,707. Fertilizer distributers. BREEZE, C. A. July 12, 1943, No. 11242. (Class 6 (i)] A fertilizer distributing machine comprises a hopper 41 from which the material is fed by worm 43 on to two endless conveyer belts 30 inclined upwardly towards the respective extremities of the machine. As it travels outwardly, the material is ejected over the sides of a trough 10 by stationary or oscillated frames 34 having scrapers 35 of V- or other suitable shape. The outer belt pulleys 20 are driven by bevel gearing and a shaft 22 extending the full width of the machine and rotated by a gear 23 and gear-box 24 connected to a power-shaft 7 on the tractor-drawn vehicle 8. The scraper frames 34 may be mounted on U-shaped springs 36, Fig. 6, secured to the trough sides 10 and may be oscillated transversely by eccentrics 37, Fig. 5, on the shaft 22 and levers 38 pivoted to the frames and trough. The belts 30 are supported on false bottoms 31, hinged at 32 to the frame carrying the inner pulleys 25 and supported at the outer ends by members 33 on the trough. The frame carrying the inner pulleys is adjustable vertically to vary the inclination of the belts by screw and hand wheel 28. The worm 43 is driven by bevel-gear 44 and chain from the shaft of one of the pulleys 25 and has a floating block 46 resting on the belts to prevent material falling between the pulleys. The belt tension is maintained by spring-controlled links 49 connected to collars 47 on the pulley shafts which are slidably carried in slots in the frame, Fig. 3. The frame of the distributer consists of members 12 ... 16 carried by angle members 11 extending from the vehicle platform. The rate of distribution of material may be varied by a variable speed in the gear-box 24 or by altering the gear ratio 21 or by vertical movement of the pulley frame by the hand wheel and screw 28. The trough may be in two parts, the inclination of which to the horizontal may be adjustable, the conveyer belt being then maintained horizontal. The inner pulleys may be gear driven and the belt-tensioning means applied to the outer pulleys 20. The outer ends of the trough are supported by struts 17 braced by a rod 19.

Abstract: 561,395. Stud fastenings. JARRETT, F. Aug. 13, 1942, Nos. 11337 and 14392. [Class 44] In a stud fastening for aircraft cowling panels, and like uses and of the kind in which a stud 12 rotatably mounted in the panel 1 has lateral projections which pass through an elongated aperture in the support and are brought, by giving the stud rotation through approximately 90‹, into position transverse to the opening and into co-operation with cam surfaces carried by the support, the cam surfaces are associated with a tapered guide which leads the stud into correct engagement if the parts are slightly out of register. As shown, the tapering guide 17 is tubular, of oval cross-section and with a terminal flange 18 formed with cam surfaces 26 up which the surfaces 15 of a T-form stud end 14 ride into snap-engagement with depressions 27, rotation towards fastening position being limited by shoulders 28. Flange 18 also serves for attachment of the guide to one limb of a U-form spring 19 the other limb of which is secured to the support 2. In one alternative arrangement the spring is of arched form with in-turned or out-turned feet secured to the support, and in. another form the spring is replaced by a rubber bush within which the guide is mounted. In all cases the inner end of the guide is spaced from the support far enough to allow the requisite play of the spring or bush for fastening and release purposes, but abuts against the inner face of the support under undue strain to offer solid resistance to separation of the panel from the support and to limit distortion of the spring or bush. As shown in Fig. 1 the leading end of the stud end 14 is rounded and the faces 15 are inclined to the stud axis, and in Fig. 3 these parts are also rounded transversely whilst the. sides are inclined and merge into a reduced portion 13 of the stud shank. The stud has a countersunk head 10 with screw-driver slot 11 and seats flush in a sunk portion 30 of a stiffener 3 secured to panel. 1. An ejecting spring 29 may be used .below the head 10 to raise it above the surface of the panel when the stud is in release position. The aperture in stiffener 3 is smaller than stud head 10 and end 14, and the stud is rotatably anchored by forcing end 14 through the aperture and then tapping out any distortion of member 3'which results.
