A suspension unit consists of a fluid spring or equivalent load supporting means of the piston-cylinder type in combination with an hydraulic piston-cylinder damper, the cylinder 17 of the fluid load-supporting means being carried by the piston rod 6 of the damper and surrounding the cylinder 1 of the latter. The load-supporting pressure fluid is located in an annular space 17A between the two cylinders, which space is axially bounded by an end closure 16 secured to the outer cylinder 17 and by a piston 65 which is secured either (as shown) to the inner cylinder or to the outer one, and is slidable over the other. This piston is sealed by a resilient washer 75 loaded by a spring 79 as well as by the pressure of fluid in the space 17A. This fluid is either gas, constituting the effective suspension spring, or liquid connected (by way of a conduit connection 84) to a separate liquidpressurizing spring means. The construction of the damper 5, 6 is evident from Fig. 1; 35 and 51 are subsidiary pistons for cushioning the end-of-stroke in each direction and the damper fluid is a liquid-gas emulsion.

Title: Improvements in and relating to granular ammonium nitrate compositions
Inventor: SHERRINGTON PETER JOHN
IPC: C01C1/18
Filed: 1962-11-28
Abstract: Granules of ammonium nitrate are formed by spraying a melt of ammonium nitrate containing not more than 6% of water into a zone containing an agitated bed of ammonium nitrate granules while a gas, e.g. air or fuel combustion gases, passes therethrough, and the granules are showered through the gas so that they become coated with the dispersed ammonium nitrate and substantially dry enlarged granules are removed.  The process may be operated in a drum provided with lifters. The melt may be sprayed through one or more vortex spray nozzles or air-operated atomizers either at the inlet to the zone or on to the bed of granules.  The process is operated continuously and the fines, crushed oversize, and, if desired, product size granules are recycled.  The ratio weight of ammonium nitrate sprayed: weight of recycled granules fed per unit time is from 1 : 2 to 3 : 1.  The grading of the product is 1 to 4 mms. and that of the feed 0.5 to 2 mms. The melt to be sprayed may be kept 10-20 DEG  C. above its melting point.  The melt may be produced in situ by reacting nitric acid and ammonia, concentrating the solution in a falling film evaporator, or in a Stengel reactor/evaporator, and feeding the hot solution to the nozzle. The gas stream may be countercurrent at ambient temperature, or co-current, when the gas is heated preferably so that the outlet temperature of the gas is 60-120 DEG  C.  When the water content of the melt is 3-6% the granules are porous, e.g. 15-26%, and with water content not more than 0.5%, dense, e.g. 7-15% porosity granules are formed.  Minor proportions of aluminium, magnesium or calcium oxides or salts, e.g. nitrates, may be included in the melt to modify hardness, crystal habit, and storage properties.  Thus, 0.5% MgO or 2% Al2(SO4)3.  18H2O may be added. Specification 894,773 is referred to.

Abstract: 1372254 Pneumatic tyres MICHELIN & CIE 29 Sept 1971 [30 Sept 1970] 45436/71 Heading B7C An unused or retreaded pneumatic tyre has a tread made of a vulcanized mixture based on an elastomer, e.g. rubber, the elastomer being oriented in a direction parallel to the groundengaging surface of the tread and not at right angles to the circumferential direction, e.g. the circumferential direction. The orientation of the elastomer is produced by stretching the unvulcanized tread prior to or during its being wrapped around the tyre carcass during manufacture of the tyre, the stretching being effected at least in the wrapping direction and producing an extension in the wrapping direction of 75-600%. The tread may comprise a plurality of layers of the mixture each 0À1-5 mm. thick, the layers being produced either by superimposing a plurality of sheets of the mixture on the tyre carcass or by wrapping a number of convolutions of a single sheet of the mixture around the carcass. Alternatively the tread may be made from a prefabricated member of profiled cross-section and in this case the extension to which the unvulcanized tread is subjected may be greater than that desired in the finished tyre and may exceed the elastic limit. A tread of layered construction in which the elastomer is oriented in the circumferential or wrapped direction may be produced on the apparatus shown in Fig. 1, wherein a tyre carcass 1 mounted on a wheel 2 is driven at a constant circumferential speed VI by a motor 3 regulated by a feeler 4, and tread strip 10 is drawn from a supply rool 15 through a compensator 19, which allows the roll 15 to continue to supply between successive tread applications, to driving rollers 20, 21, 22 which drive the tread strips 10 at a constant speed V 0  lower than the speed V 1  of the carcass, the strip thus being stretched by an amount proportional to the ratio V 1 /V 0  at the instant of its application to the carcass. Knives 24 are provided for cutting the strip 10 and there is a spool 18 which receives fabric or polyethylene sheet interleaving the strip 10 on the spool 15.

In a fluid heater cleaner having a nozzle which may be advanced from and withdrawn to a retracted position and flexible driving means extending in the direction of reciprocation of and coupled to the nozzle tube to determine longitudinal movements thereof, there are emergency stopping means normally maintained inoperative by the flexible driving means but adapted upon rupture of the driving means to become effective in preventing or limiting forward movement of the nozzle tube under the force exerted by the cleaning fluid. The flexible driving means may be an endless duplex chain 53 driven by a reversible electric motor 45 and coupled to a nozzle tube supporting carriage 24 adapted to run to and fro on a track 7. As shown, a catch 65 is pivoted on the bottom plate 67 of the carriage 24 and serves, when effective, to positively lock the carriage against forward movement; the catch is connected to a spring 70 for biasing the catch to the operative position thereof and against a stop 73. The chain 53 is connected by springs 76 to the catch which acts like a pawl in cooperation with a number of stops 72 to permit rearward movement of the carriage. Failure of the chain or connection between the chain and the carriage allows the spring 70 to move the catch to the operative position thereof to result in engagement of the catch with one of the stops 72.
