Abstract: 899,210. Stuffing-box substitutes. VOITH G.m.b.H., J. M. Dec. 9, 1960 [Dec. 17, 1959], No. 42519/60. Class 122 (5). Lubricant under pressure between relatively rotatable machine parts, e.g. a stationary housing 1 and a rotatable shaft 2, Fig. 1, is sealed off by a resilient metal ring 3 located with slight axial and radial play in a groove 4 in one of the parts, the ring, the walls of the groove and the surface of the opposite machine part being of such dimensions and shape that, under the influence of forces arising from the lubricant pressure, the ring resilience and, when the ring rotates, centrifugal force, the ring bears on one of the machine parts with higher frictional resistance than on the other part, the sealing surface of the ring and/or of the corresponding machine part associated with lower frictional resistance being provided with lubricant pockets 6 which communicate with the space 8 containing the lubricant. The groove 4 is recessed at 10 and the pockets 6, Fig. 2, may be punched out in the form of sections of a cylinder. When the shaft 2 rotates the frictional resistance is greater at 7 than at 5 so that the ring remains stationary. In a modification, the lubricant pockets are formed in the housing and the ring rotates with the shaft.

Title: Fuel injection devices
IPC: F02M55/02
Filed: 1971-09-17
Abstract: 1364561 Fuel injection pumps; regulating I C engine fuel injection ROBERT BOSCH GmbH 17 Sept 1971 [18 Sept 1970] 43414/71 Headings F1A and F1B [Also in Division F2] A fuel injection pump commences delivery when a valve 24 in a return line from the pump delivery chamber 19 is closed, preferably electrically, the delivery passing to whichever injection line has an open electromagnetic valve 28. An electronic control device (not shown) supplies electrical pulses for causing, during each delivery stroke, first closure of the valve 24, then closure of the open valve 28. Hence the control device determines the timing of injection and the quantity delivered. When both valves are closed the delivery is admitted to a gas or spring-loaded variable volume reservoir 1 or flows to exhaust through a relief valve (not shown). During the next delivery stroke the return valve 24 is opened first followed by another of the valves 28 whereafter the above sequence is repeated. Four possible valve constructions are described (See Division F2) and each comprises a pot magnet arranged to attract a non or spring-loaded valve member towards either a closed or an open position.

Title: Improvements in and relating to a variable load control valve for a rail vehicle braking system
Inventor: SHATTOCK CHARLES FREDERICK BAY
IPC: B60T8/18
Filed: 1962-01-03
Abstract: 941,225. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. Jan. 3, 1962, No. 43520/62. Divided out of 941,224. Heading F2F. In a variable load control valve for a railway braking system which varies the brake cylinder pressure in response to changes in the load carried by the vehicle, a weigh beam 32 is mounted for longitudinal movement between positions E (empty) and L (load), spaced abutment members 55, 56 engage the weigh beam for varying the brake cylinder pressure upon movement of the weigh beam between the positions E and L and guide means, formed by a pivotally mounted link 58 or 59, is associated with each abutment member for preventing lateral stress thereon. The control valve is provided with two air inlet connections 44 and 46 leading from a triple valve or EP unit and from a main reservoir respectively. An air outlet connection 47 is connected to the brake cylinder relay valve. The air passes from the connection 46 to the outlet 47 through an inlet valve 48 and can exhaust through an exhaust valve 49. A diaphragm 50 extends across the upper portion of the valve body 43 and is subject to the required output pressure to the brake cylinder relay valve. A diaphragm 42 extends across the lower portion of the valve body 43 and air from the triple valve or EP unit acts on the underside of the diaphragm 42. In operation, when a pin 18 is in the position E, the weigh beam 32 is in the position shown in the drawing and the ratio is such that a pressure of 50 1b. per square inch acting on the underside of the diaphragm 42 produces a load on the diaphragm abutment 56, corresponding to the pressure acting on the diaphragm 42 multiplied by the effective area of the diaphragm 42 multiplied by the leverage ratio produced by the positions of the abutments 55, 56 and the pin 31. This load is balanced by a pressure above the diaphragm 50 which is equal to the required brake cylinder pressure, for example 50 1b. per square inch. Any intermediate pressure under the diaphragm 42 produces a proportional output pressure above the diaphragm 50. Specification 927,001 is referred to.

Title: Capsular units consisting of clusters of capsules contained on outer encapsulating wall and a process for producing the same
IPC: A61K9/50
Filed: 1959-12-31
Abstract: Capsular units, each consisting of a cluster of individual capsules surrounded by an outer capsular wall and each capsule consisting of a substantially water-insoluble core surrounded by its own capsular wall, are prepared by dispersing discrete entities of the core material in an aqueous sol of a plurality of film-forming polymers having fractions of different molecular weights which are capable of undergoing coacervation under two sets of conditions, adjusting the condition of the sol-dispersion to one of the said sets of conditions to cause a part of the polymer materials to deposit as liquid walls around each of the core entities whilst the sol-dispersion is continuously agitated until clusters of the liquid walled entities form, thereafter changing the conditions to the second set of conditions to cause the remaining polymer material to deposit by coacervation around individual clusters and thereafter solidifying and optionally hardening the liquid wall materials around both the individual capsules and clusters thereof.  Specified film-forming materials are: gelatine, gum arabic, chondrus, zein, soya bean protein, polyethyleneimine, polyvinyl methyl ether-maleic anhydride and polyethylene-maleic anhydride copolymers.  Coacervation may be induced by the successive alteration of the pH of the aqueous sol to values within two suitable pH ranges or by the similar alteration of solubility conditions.  The core material may be a vegetable, animal, mineral or synthetic oil with or without additional dissolved or dispersed material or substantially water-insoluble solids.  By mixing dispersions in which different core materials have been formed into individual capsules and subsequently causing the second coacervation to occur, products containing a plurality of differing individual capsules within a single outer mantle may be formed.  A wide variety of materials which may be encapsulated are mentioned in addition to the above-mentioned oils, e.g. pharmaceuticals such as salicylamide, tetracycline hydrochloride and phosphate, phenaglycodol, cholorotrianisine, cholesterol, meprobamate, erythromycin propionate, benzathine penicillin G, Vitamins A-palmitate, B2 and K; flavours, aromatics and perfumes, e.g. cocoa-butter, coffee oil, musk, citronella, spearmint and palm oils; solids, e.g. magnetic iron oxide, calcium carbonate, zinc sulphide, carbon black, solid catalysts and polymer materials, bentonite and titanium dioxide.  Specification 751,600 is referred to.

IPC: C08L95/00
Filed: 1960-12-29
Abstract: Bituminous compositions for use in manufacturing waterproof sheet comprise 20-60% by weight of an asphaltic cement, 30 to 70% by weight of a mineral filler and 5 to 25% by weight of reinforcing fibre. "Asphaltic cement" is defined as asphaltic bitumen and/or natural asphalts, or a mixture of one of them with fine mineral aggregate, prepared for use as a binder for mineral aggregate and is preferably a blend of asphalt and/or asphaltic bitumen with a bituminous or polymeric binder.  The binder may be synthetic or natural rubbers, elastomers, tars, oxidized bitumen, thermoplastics (e.g. polymerized olefins) or uncured thermosetting materials (e.g. epoxy or polyester resins) and the viscosity of the cement should exceed 9 kilopoises at 25 DEG  C.  The asphalt or asphaltic bitumen may include "Gilsonite" (Trade Mark), natural lake asphalts, residual bitumens or light-coloured bitumen and asphaltic resins. When using light bitumens a small proportion of heat-stable pigment may be included in the composition. The ratio of asphaltic cement to mineral filler is about 2:3 and preferably at least 70% of the filler, which may be a pulverized calcareous material or an impalpable material (e.g. amorphous silica, aerosils, diatomaceous fillers, reformed bentonites, kaolin, fly ash, mica or vermiculite, passes a 200 mesh sieve.  The reinforcing fibre may be asbestos, glass fibre, slag wool, non-ferrous metal fibre or synthetic fibre. The bituminous compositions may be made by heating the asphaltic cement to a temperature not exceeding 200 DEG  C., adding the filler and fibre and working the composition while still warm and malleable into sheet form by extrusion through a die or passage through a pair of rollers. The sheets may be backed with, for example, woven hessian, glass fibre cloth, paper, metal foil, chemically setting resin or varnish and surface stickiness may be inhibited by treatment with a surface-active agent (e.g. silicones, fatty acids or long-chain amines).
