Title: Improvements in the partial depolymerisation of highly polymerised polymethyl methacrylate
IPC: C08F8/50
Filed: 1947-01-01
Abstract: The softening point of highly polymerized polymethyl methacrylate is lowered by heating the comminuted polymer to a depolymerization temperature of at least 175 DEG  C. until at least 10 per cent by weight, preferably 15-25 per cent, is volatilized, the remainder being obtained as a solid polymer suitable for injection moulding. Preferably, high-frequency electrical heating is employed and the product is blended, e.g. on hot rollers, prior to use.  Provision is made for the recovery and repolymerization of the monomer produced and volatilized during the process.  In examples, the polymer (40-50 mesh) was heated (1) in an oven at 220-240 DEG  C. for 30 mins. in layers 0.25-0.38 ins. thick and (2) in a paper frame between the electrodes of a 10 kw. H.F. heating unit for 22-24 mins.ALSO:In a process for lowering the softening point of highly polymerized polymethyl methacrylate the comminuted polymer is heated to a depolymerization temperature of at least 175 DEG  C. until at least 10 per cent by weight, preferably 15-25 per cent, is volatilized due to the formation of monomer.

Abstract: In the preparation of lead alkyls from lead-sodium alloy and alkyl halides, the reaction mixture is treated with water and steam distilled, first in the presence of a dispersing agent and then in the presence of a wetting agent, whereby the whole of the product is recovered.  Dispersing agents mentioned are engine oil, thiocarbanilide, sodium chromate or dichromate, sodium thiosulphate and sodium silicates.  Sulphonated natural oils such as castor oil and monopole oil are particularly useful as wetting agents: others referred to are the salts of alkylnaphthalene sulphonic acids; the condensation products of naphthol sulphonic acids and formaldehyde; the reaction products of oleic acid and aliphatic diamines; the higher fatty and unsaturated acids and their soaps, e.g. sodium and potassium stearates and triethanolamine stearate and oleate; the resinates; the mixture of pine oil and aqueous sodium isopropylnaphthalene sulphonate known as "Merpentene"; and the sodium alkylated naphthalene sulphonates known under the Registered Trade Marks "Leonil S" and "Nekals."  According to the example, ethyl chloride is reacted in an autoclave with a lead-sodium alloy, the product drowned in water to which a little engine oil and thiocarbanilide have been added, and the lead tetra-ethyl removed by steam distillation; when no further product comes over, turkey red oil is added to the still and the steam distillation continued to remove the final traces of lead tetra-ethyl.  U.S.A. Specification 1,645,375 is referred to.

Title: Hydraulic booster for forklift brake
Inventor: IDETA YASUFUMI

Abstract: PURPOSE: To improve the safety by providing some extent of a boosting function at malfunction by a mechanism wherein a lift cylinder internal pressure is allowed to apply to the booster chamber for the shortage of operating oil due to malfunction of a pump.  
     CONSTITUTION: On operating a brake pedal 19, a spool 42 is displaced to the right by means of a rod 66 to permit a throttle valve 49 to throttle the operation oil flow passing therethrough. This allows to produce the hydraulic pressure at upper stream thereof, where the hydraulic pressure is applying to a boost chamber 32 passing through groove 29a and perforations 42i, 42g, 42h that produce a large braking hydraulic pressure by pushing the right and end of the power piston 29. In this case, for the shortage of operating oil due to malfunction of a pump 1, the flange 33a of a rod 33 allows to strike a shock absorber 45 to open an operating valve 51. Consequently, a control valve is opened, and the throttle valve 49 and a return valve 50 are closed, permitting the hydraulic pressure within the lift cylinder to apply to the boost chamber 32 by passing through port 54, vertical groove 29j, and perforation 29p and the like.
