Title: Improvements in or relating to the supply of air to burner fed furnaces or the like
IPC: F23C99/00
Filed: 1926-07-08
Abstract: 255,080. Burroughs, C. W. July 8, 1926. Pulverulent. liquid, and gaseous fuel furnaces. - Fuel is fed axially into a cylindrical combustion chamber, Fig. 1, from a burner 2 and is supplied with air under pressure through a manifold 3 and radial passages 30, 300 at different distances from the burner and in different directions so as to produce opposed vortex zones across the path of the burner flame. Deflectors 32, Fig. 3, are provided at the exits of the radial passages to produce the whirling movement of the air. According to the Specification as open to inspection under Sect. 91 (3) (a), the deflectors 32 are connected to rods and may be adjusted by rack and pinion gearing. This subject-matter does not appear in the Specification as accepted.
Patent GB-599628-A (GB)
Title: Improvements in the manufacture of concrete and like slabs
IPC: B28B1/087
Filed: 1945-07-05
Abstract: 599,628. Shaking-machines. ALLTOOLS, Ltd., and HALL, E. H. S. July 5, 1945, No. 17165. [Class 87 (ii)] The mould 11, travelling on a conveyer 10, engages the spring-loaded trigger 13 which operates a switch 34 to start the motor 23 driving, through reduction gear 24, shaft 28 and dog clutch 25, the cam shaft 22. The jolting frame 16, which is attached to the main frame 14 by parallel links, is thereupon raised on the portions 42 of the cams 35 on the shaft 22, lifting the mould off the conveyer and allowing the trigger 13 to return into position for engaging the next mould. The motor 23 continues to run, so that the teeth 39 on the cams 35 jolt the mould a number of times (e.g., eleven times in half-a-minutes) each jolt consisting of a slow rise as the rollers 36 run up the faces 40 and a sudden drop as they run down the faces 41. During this drop the shaft 22 may overrun the shaft 28, a lost motion being provided between the teeth of the clutch 25. Cams 60, 61 on the shaft 22 raise pivoted links 44 from an inclined position to the upright position shown in Fig. 3 so that they limit the downward movements of the frame 16 and prevent the mould from dropping on to the conveyer. At the conclusion of the jolting movements the cams 60, 61 and 35 move the links 44 back to an inclined position and lower the frame 16 so that the mould is lowered on to the conveyer. A cam 49 on the shaft 22 then operates a switch to stop the motor 23 when the shaft has completed one revolution. The frame 16 may carry a buffer to arrest a mould which is following too closely behind the one on the jolting frame. Specifications 533,175, 589,449 and 599,619 are referred to.

In a modification, the clip is formed with substantially U-shaped deformations 11, 12 and 13 and is split at at least one position to define ends 16 provided with apertures 17 in which is engaged a spring member 18 enclosing a cylindrical piece 21 of resilient material; the crown of the loop of the member 18 may have an indentation therein.
Patent GB-675547-A (GB)
Title: A process for improving the properties of polymerisation products from styrene
IPC: C08F8/00
Filed: 1950-07-11
Abstract: Polymers and copolymers of styrene are improved by treatment in comminuted form with steam at a temperature above 100 DEG  C., but below the decomposition temperature, e.g. 110 DEG  to 180 DEG  C., and removing the constituents which are volatile in steam.  An aqueous suspension of beads or small grains may be stirred in a closed vessel which is heated internally by superheated steam or externally by a jacket.  To avoid agglomeration of the particles, polyvinyl alcohol, polyvinyl pyrrolidone, bentonite, talcum, glycol, glycerine or salt may be added to the water.  The treatment may take place in the polymerization vessel, Alternatively dry, superheated steam at ordinary or reduced pressure may be used.  The treatment raises the softening temperature and increases the impact bending strength.  In examples (2) styrene is polymerized in a stirring autoclave at 80 DEG  C. in the presence of an aqueous polyvinyl alcohol solution and benzoyl peroxide to form beads, the temperature is then raised to 140 DEG  C. for 10 hours and the steam formed is continuously released; (3) a styrene-acrylonitrile bead copolymer is suspended in water and heated at 150 DEG  C. for 12 hours.

Title: Improvements in or relating to evaporating and crystalling liquids
IPC: B01D9/00
Filed: 1938-06-10
Abstract: <PICT:0496193/III/1> In the crystallization and/or vacuum evaporation of liquids, e.g. saline solutions, in stages with the aid of air introduced as a stirring medium, the air is admitted into the successive stages under a pressure which is decreased as the degree of vacuum is increased in the successive stages.  The same quantity of air is preferably used in each stage, e.g. about 20-80 cubic metres per stage.  An evaporator 1 is divided by partitions 2, 3, 4 into four stages into which air is injected by valved pipes 30-33. Air and vapours are taken off through lines 7 to a common condenser 8 and in the stages of higher vacuum the gases are compressed by steam injectors 9-11.  Cooling water is injected into the condenser 8 by a pipe 12 and the gases are removed by a steam injector 13 to a condenser 14 where the steam is condensed and from which air is evacuated and returned to the cycle by a pump 15.  The temperature of the solution in the different stages is for example 25, 15, 8, and 2 DEG  C.

As shown in Fig. 2 the pneumatic suspensions comprising cylinders 7 and pistons 9 attached to the axle 11 are in communication with control means through pipes 6 having throttling means 8 whereby air circulation between the cylinders 7 and the control chambers is restricted during oscillations of the axle while permitting equalization of pressure under static conditions. The control means comprise air chambers 1 having pistons 2 controllable by the driver through screw hand wheels 3. Fig. 4 shows another arrangement wherein the cylinders 7 are placed in communication with one air chamber 1 the pressure of which is controlled by an accumulator 17, 19, a valve 20 being employed to allow the pressure of the accumulator to have access to the air chamber 1 and a pump 21 in parallel to pump oil out of the chamber 1 into the accumulator to decrease pressure.
