Class 9(1) A direct-action fuze for rotated projectiles provided with self-destruction means comprises a spring-stressed sleeve 1 slidable in the fuze body 2 and bearing against a flange on the firing pin 4 to urge the pin towards a primer 5. While the angular velocity of the projectile exceeds a given value, balls 6 housed in radial recesses in the sleeve 1 bear against inclined surfaces 7 of an outer sleeve 8 to prevent movement of the sleeve 1 towards the primer. So that the inner sleeve 1 shall rotate with the same velocity as the sleeve 8, a finger 10 projects from sleeve 8 into a groove 9 in sleeve 1. In a modification, Fig. 3, the outer sleeve 11 is also slidable in the body 2 and bears against centrifugal masses 12 which lock the firing pin. The outer sleeve is keyed to the inner sleeve by a projection 10‹ engaged in a groove 9‹. The outer sleeve may be positively coupled to the fuze body 2. Specification 605,683 is referred to.

In a method and apparatus for cleaning the components of disassembled syringes, the components are subjected in a centrifugal washing machine to centrifugal action on the one hand and the action of at least one radially directed liquid jet on the other hand. As shown in Fig. 1, the centrifugal washing machine comprises a fixed casing a, a hollow drum b rotatable about its vertical axis and provided with wall perforations b<SP>1</SP>, and a vertical liquid 'supply tube c<SP>1</SP> having slot-like nozzles c<SP>2</SP> to project radial liquid jets. The hollow components of the syringe, when disassembled including the piston and its piston rod, are resiliently secured in a two-part perforated container m, n, Fig. 4, which is of rectangular shape and open at its ends. The upper U-shaped portion n constitutes a cover for the lower U-shaped portion m and is hinged thereto at m<SP>1</SP> at each side. 'Cross-bars o<SP>1</SP>, o<SP>2</SP> secured in the portion m are adapted to support the glass syringe cylinder p<SP>1</SP>, piston rod with piston and cylinder holder (not shown). Those components are engaged by pairs of U-shaped springs of which one pair r<SP>1</SP>, r<SP>2</SP>, only, is shown, the springs being carried by the cover n. The syringe needle holder p<SP>4</SP> is carried in a slotted pedestal o' on the portion m. A catch f pivoted to m engages a groove n<SP>1</SP> in the cover n to maintain the latter in its closed position. The syringe needles e, Fig. 5, are carried in funnelshaped holders d which are loosely mounted in the perforations b<SP>1</SP> from the inside of the drum b. In operation the containers m, n and their components are stacked inside the drum as shown in dotted lines in Fig. 1, and the funnels d project outwardly from the drum. On rotating the drum, the funnels d adopt horizontal and radial positions and all the components are subjected to the action of the radial liquid jets, emanating from-the nozzles c<SP>2</SP> and also to centrifugal action. The containers and components are subsequently transferred to a sterilizer.

Abstract: 1510527 Gas distribution systems FOSTER WHEELER ENERGY CORP 4 Sept 1975 [5 Sept 1974] 36508/75 Heading F4X In a gas flow line wherein excess gas (i.e. a gas purge) from a source such as a petrochemical or refining installation is directed through a line 14 en route to a flare or other burner where the said gas purge is burned, the gas line conveying said gas purge to the burners includes between conduits 20 and 28 thereof a liquid seal such as a tank 22 containing a liquid (e.g. water) and connected to a reservoir 24. The inlet end of the conduit 28 is normally below the liquid level in the tank 22 whereby gas flow to burners 32 via conduit 28 is prevented. In use, any relatively small gas purge from the source is routed via lines 14 and 20a to burner 34. If the quantity of purged gas increases beyond the capacity of burner 34 the excess is routed via vessel 22 wherein as the gas pressure rises, the liquid level is forced down below the end of conduit 28 so allowing gas to flow to burners 32. A charge of inert gas is maintained above the liquid level in tank 22 when no gas is passing therethrough to burners 32. This is to prevent diffusion of air from the burners 32 (when inoperative) into the line 20 via the tank liquid.

Title: Improvements in the manufacture of petroleum resins
IPC: C08F240/00
Filed: 1962-09-26
Abstract: A petroleum resin having a particular colour and softening point and made by polymerizing a steam-cracked hydrocarbon stream containing monomeric and dimeric cyclodienes, is prepared by adjusting the ratio of monomeric cyclodienes to dimeric cyclodienes before polymerization by soaking the hydrocarbon stream at a predetermined temperature for a sufficient time to attain the desired ratio between the monomeric and dimeric cyclodienes at that temperature, whereby a resin of the desired colour and softening point is obtained by subsequent polymerization.  The hydrocarbon stream may be a steam-cracked naphtha containing from 4 to 5% cyclodienes and the ratio of monomeric to dimeric cyclodienes is adjusted to provide at least 1.5% of monomeric cyclodienes, based on the naphtha, whereby a resin having a colour between 12 and 13 Gardner units and a softening point between 95 DEG  and 105 DEG C is obtained by subsequent polymerization. Apparatus for carrying out the process is described.

Title: Process for the treatment of solutions of chlorinated rubber
IPC: B04B9/06
Filed: 1934-12-27
Abstract: A process for the reduction of the viscosity of solutions of chlorinated rubber comprises subjecting them to violent mechanical treatment producing shearing stresses within the solution.  For example the solution may be passed, under pressure if desired, through a homogenizer, a colloid mill or a paste mill one or more times; the precise type of machine used depending upon the initial viscosity of the solution to be treated, the solution may be passed first through one type of machine and then through another. The apparatus may be cooled to prevent overheating.  Other methods of reducing the viscosity of solutions of chlorinated rubber may be combined with the violent mechanical treatment, e.g., the solution may be subjected to a preliminary or subsequent ageing and/or exposure to light.

Title: Method and apparatus for polishing glassware

IPC: C03C15/02
Filed: 1968-08-05
Abstract: 1278268 Polishing glassware C C MAYERS and I L SMART 5 Aug 1969 [5 Aug 1968] 37287/68 Heading C1M A method of polishing glass articles comprises placing the articles in a vessel, directing a stream of suitable glass polishing acid over at least a part of each article and then, while the articles remain in the vessel directing a stream of rinse liquid over the articles. Prior to the main acid treatment the articles may be washed in the vessel with a water and detergent mixture and then sprayed with a "spiking" acid, i.e. a mixture of a high proportion of sulphuric acid and a small proportion of hydrofluoric acid. Following the acid treatment the articles may be mixed with a neutralizing solution and then rinsed with lime-free water. These processes are all carried out in a gas-tight acid resistant vessel 13 equipped inlet ports 14 and associated spray nozzles 15 and an outlet port leaching through a filter bag 16 to a sump. The liquids used are stored in closed tanks 18 which are connected to the ports 14 via a pump and selector valve. A sump 17 is associated with tank 18 so that the liquids may be returned from the vessel 13 to the respective tanks. The glass articles are carried in plastic-coated wire baskets supported on a holder 23 which is attached to an agitating device 24. The acid strength may be monitored by measuring its impedance, by passing radiofrequency electromagnetic radiation therethrough, and its density, using ultrasonic  means.
