Title: Reforming of naphtha
IPC: C10G59/00
Filed: 1936-04-09
Abstract: The anti-knock characteristics of naphtha are improved by separating the naphtha are improved by separating the naphtha into fractions of different boiling ranges of substantially 100 DEG  F., and subjecting the fractions to separate thermal refining treatments at temperatures above 800 DEG  F., in presence of catalysts comprising mixtures of silica and alumina, the refining conditions employed for treating each fraction being different. The naphtha is preferably separated into fractions of the boiling ranges of 250--375 DEG  F., and 375 DEG F. to end point, and each fraction is treated to obtain a product of 75 octane value which is separated, the residues being re-treated repeatedly.  The refining conditions comprise temperatures of 850--925 DEG  F., pressures of 15--300 lb., and feed rates of 3 : 5 to 7 : 5 of oil to catalyst per hour.  The silica-alumina catalyst, in which the weight ratio of silica to alumina should be at least three to one, may be formed by precipitating silica or alumina or viceversa or by combining silica gel with alumina, or by treating natural clays, e.g. fuller's earth, bentonite, &c., with acids, alkalis or phosgene, and using the product to build up with silica to the desired weight ratio.  Small amounts of the following metals may be added, iron, lead, copper, manganese, vanadium, molybdenum, chromium, tungsten.  Gases, e.g. steam, methane, ethane, propane, butane, hydrogen, may be added to the charge.

Title: Improvements in flexible joints
IPC: B61D33/00
Filed: 1928-04-10
Abstract: 289,461. Flintermann, G. April 28, 1927, [Convention date]. Flexible couplings.-In flexible joints of the kind in which the movement between two re<l>atively movable members is yieldingly resisted by an interposed body of resilient material the inner and outer members of the joint are in the form of an elongated annulus or one or both of these members are tapered, the flexible material such as rubber or leather being arranged between the relatively movable parts, or substantially enclosed by one of them. The application to shaft couplings is referred to. As described with reference to a joint for a seat, the flexible material 4 is interposed between a bracket 3 attached to the base 2 and the supporting standard 1. The material is enclosed in sheet metal plates 5, 6 formed with a flange 7 to be secured to the bracket 3 and side flanges 11, 10, there being also a web 16 forming an elongated annular channel member 16 which grips and holds the inner edge portion of the resilient material. The composite member receives the closed end of a stamped sheet-metal member 18 secured to the standard 1, the parts 12, 13 and 18 being riveted together at 19. The major axis of the joint is inclined as shown, when the resilient material allows vertical movement of the seat and also a pivotal or tilting movement. When the seat tilts the resilient material is compressed at the points a, b, and at these places the material may be provided with openings 27 to permit the material to flow. The annulus of the resilient material may also be divided into several portions as shown at 28, 29. As shown in Fig. 6, the resilient material 4a is thickened at the parts a, b where the maximum compression will occur. Other similar shapes of the resilient material are also described and illustrated.

Title: Improvements in or relating to projection systems
IPC: G03B21/20
Filed: 1930-04-03
Abstract: 354,246. Optical-projection systems. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin.-(Assignees of Projector Ges. ; 28, Wilhelmstrasse, Berlin.) April 3, 1930, No. 10601. Convention date, Feb. 7. [Class 97 (i).] A projection system consisting of a source of light, a condenser system, and an objec. tive is characterized by such a construction of the condenser sys. tem that the image points produced of the source of light lie in an infinite number of planes and these fill up a space in which or in the vicinity of which the object is located. As shown in Fig. 1 the condenser K produces a distributed image R at the picture aperture B of the source of light L and of its image L<1> produced by the concave mirror H. The aperture of the condenser K is increased, and thereby the illuminating effect of the whole system, either by grinding out the condenser lenses in their central parts, as shown in Fig. 1, or by replacing parts of the condenser with higher refracting material. The radii of such additional central lenses may correspond to those of the other condenser lenses, as shown at b, c in Fig. 3, or may be chosen arbitrarily, as shown at d in Fig. 4. In order to obtain a suitable projection objective for use with such condensers, the total length of the objective is considerably reduced in proportion to its focal length. As shown at O in Fig. 1, the first lens e is a simple convex lens of focal length less than four times the focal length of the whole objective. Two compound collective lenses f, g are also used, e and f together being corrected spherically according to Abbe's condition. The third lens g serves for the alteration of the focal length of the whole system and to compensate for faults in picture sharpness. The objective may be chromatically corrected by a suitable mutual arrangement of the individual lenses.

Filed: 1966-03-14
Abstract: 1,156,842. Valves. C.A.V. Ltd. 14 Feb., 1967 [14 March, 1966], No. 11020/66. Heading F2V. A fluid pressure regulating valve comprises a tubular housing 10, the bore of which is stepped, a cylindrical sleeve 15 disposed in the bore and biased towards its blind end by a spring 17, and a piston 19 movable within the sleeve. Upon the application of fluid pressure to the valve inlet 12, the piston 19 is moved, against the force of springs 20, 21, from the position shown into one in which an annular groove 24, formed in the piston, communicates with an outlet 23 formed in the sleeve 15, so allowing fluid to flow from the inlet 12 to an outlet 13. Application of a higher pressure raises the piston still further so reclosing outlet 23 until the pressure is sufficient to raise the piston above the outlet, at which stage, full flow through the outlet takes place. In a liquid fuel pumping apparatus, for supplying fuel to an internal combustion engine, fuel is supplied to a port 31 from where it passes through a filter 25 into outlet 13, which outlet constitutes the outlet of a vane type feed pump. Fluid from the pump outlet 30, which also communicates with the valve inlet 12, passes to an injector pump 50 through a throttle 51 and through an excess fuel valve 52, the arrangement being such that valve 52 permits a supply of excess fuel for starting purposes after which it becomes inoperative, whilst the regulating valve serves to maintain steady the pressure at the outlet 30 by bypassing excess pressures to the valve outlet 13.

Title: Improvements in or relating to fuze-setting apparatus
IPC: F42C17/00
Filed: 1940-07-02
Abstract: 577,004. Fuze-setting apparatus. MUSSON, A. H., HARVEY, V. P., and MOLINS MACHINE CO., Ltd. July 2, 1940, No. 11152. [Class 9 (i)] A fuze-setting apparatus of the kind in which the movable fuze ring is gripped by members, such as knife-edges, which are forced into the material of the ring, has means for rotating the gripping- device through an angle which is determined by an adjustable stop arcuately movable in a path concentric with the axis of the gripping - device. The gripping - device shown comprises a number of knives 16, Figs. 1 and 2, radially mounted between two jointly rotatable rings 58, 59. The rings are bolted to a hollow spindle or sleeve 15, on the remote end of which a gear-wheel 21, Fig. 4, is provided. A train of gearing 22, 23, 24 and a longitudinal shaft 125, enable the pinion 21 and sleeve 15 to be rotated, to effect the setting - rotation of the gripping device, by a " driving lever " 25. The extent of the rotation is determined by a stop member 28 carried by a worm - wheel 30 freely mounted for rotation on the sleeve 15. An abutment 26 rigidly mounted on the. sleeve is initially in contact with a fixed stop 27 and, to set a fuze, the sleeve is rotated by the lever 25 until the abutment 26 makes contact with the adjustable stop 28. Either or both of the stops 27, 28 may be resiliently mounted. The stop-carrying worm-wheel 30 is driven by a worm 31 on a transverse spindle 34 rotatable by a handle 35. A second worm 33 on the spindle is geared to the pointer of a receiver-dial coupled to a predictor. Operation of the lever 25 is prevented by a catch 52 until a " control handle " 51 has been actuated to rock a shaft 38 and, through an eccentric slot 39 in an arm 37 Fig. 3a, pinned to the shaft, and a roller 40 engaged therein, has rocked a bell-crank lever 141 mounted upon a transverse shaft 63. The arm 41 of the bellcrank carries the roller 40. The other arm 42 is in the form of a stirrup, the lower end 44 of which is elastically connected to a cam-device 46 which projects into the shell receiver 11 and clamps the shell in the apparatus. The arm 42 carries also two rollers 43 which are engaged in a peripheral groove 36 in a slidable ring 18, the coned inner part 19 of which engages the inclined heads 20 of the knives 16 and forces the knives inwardly, against the pressure of springs 17, to grip the fuze element.
