Title: Improvements in or relating to ratchet devices and mobile machinery employing such devices
IPC: B62D55/125
Filed: 1939-10-19
Abstract: 538,158. Locking vehicle wheels &c. RUSTONBUCYRUS, Ltd. Oct. 19, 1939, No. 28263. Convention date, Oct. 22, 1938. [Class 103 (i)] Relates to means for locking the propelling- mechanism of a mobile crane, power-shovel, &c. against motion in one or the other or both directions by means of a two-way ratchetwheel 28, Figs. 3 and 4, and opposed pivoted dogs 32, 33, either or both of which can be engaged with the ratchet. The dogs are operated by bell-crank levers 40, 41, which are connected by a rod 42. An arm 36 on the dog 32 is connected by a rod 43, having a slotted end, to an arm 38 on the dog 33. As the lever 40 is raised by the operation of a hand-lever from its lowest position, in which both dogs are out of engagement, as shown in Fig. 3, the dog 32, a boss 37 on which bears against the lever 40, is slightly lowered, and the link 43 allows the dogs 33 to engage the ratchet, as shown in Fig. 4. On further raising of the lever 40, the dog 32 also engages the ratchet. the next rise of the lever acts through the rod 42 and lever 41, which engages a boss 39 on the dog 33 to lift that dog out of engagement. The last movement of the lever 40 disengages the dog 32 also, by the action of the lever 41 on the rod 43. Both dogs are thus disengaged in the two extreme positions of the lever 40. In a modification, the bell-crank levers 40, 41 are omitted, and the dogs are operated by a sliding slotted bar 44, Fig. 8, and are also connected by a link 43 having a slot in one end. In other forms, the dogs are operated by sliding cam-bar, which can occupy five different positions, or by a bell-crank lever having pivoted at its ends two slotted links, which operate the dogs. In the case of a mobile crane &c. mounted on a turntable, the locking- device is operated from a hand-lever mounted on the turntable and acting through a rod passing through the hollow shaft of the table.

Title: Process for producing patterns resembling water-marks in foils of polyvinyl chloride and similar plastic materials
IPC: B29C67/00
Filed: 1952-11-10
Abstract: A foil of polyvinyl chloride or other organic thermoplastic material is produced by a casting or rolling process and passed without pressure over a surface which is heated to a temperature above the softening-point of the thermoplastic material and is provided with a pattern in low relief, and the heated and softened foil is then subjected to stretching.  A pattern effect resembling a water-mark is produced in the foil.  Instead of polyvinyl chloride, the thermoplastic material may be polystyrene, a polyvinyl ester, a polyester of an acrylic acid homologue, polyvinyl-carbazole, a copolymer of two or more vinyl compounds, a copolymer of an acrylic acid ester with one or more vinyl compounds, a cellulose derivative, or a chlorinated rubber.  The heated surface may be the surface of a roller and the low relief pattern may be obtained by roughening or etching.  The irregularity in the surface of the hot roller results in the foil making contact only at those places corresponding to the raised portions of the pattern.  At these portions the transfer of heat to the foil is more intense, and thereby produces in the foil especially clear areas of which the outline corresponds to the outline of the raised portions of the hot roller.  At the other parts the foil remains somewhat matt, the contrast between relatively clear and matt areas giving a water-mark appearance.ALSO:A foil of organic thermoplastic material such as chlorinated rubber is produced by a casting or rolling process and passed without pressure over a surface which is heated to a temperature above the softening point of the thermoplastic material and which is provided with a pattern in low relief, and the heated foil is then subjected to stretching.

Abstract: 1518144 Mixing processes PILKINGTON BROS Ltd 23 June 1976 [4 July 1975] 28359/75 Heading B1C [Also in Division B5] In a method of making a glass-fibre reinforced cement composite material in which chopped strands of glass filaments are mixed into a cement slurry which is then poured into a mould and allowed to cure, the cement slurry is first prepared from a cement/water mix by a high shear mixing process in which cement agglomerates are broken up into their primary particles, and the chopped strands of glass filaments are then mixed into the slurry by a relatively low shear mixing process which restricts damage to the glass fibres to a minimum. The high and low-shear mixing processes are defined with reference to a Reynolds Number in the mixing zone of over 10000 and 10 or less respectively. Alternative criteria are that the power input to the mixer is at least 5kW/100Kgs of slurry or 1kW/100Kg and less respectively. A deflocculating agent is preferably used to assist in the formation of the slurry. A suitable mixer is shown as having a four bladed rotor 10 mounted within a cylindrical cage 11 having a ring of apertures 12 in its wall and a deflector plate mounted at an adjustable distance above the cage 11. High- or low-shear mixing takes place in dependence upon the speed of the rotor 10.

Title: The production of diaminopimelic acid by fermentation
IPC: C12P13/08
Filed: 1966-06-27
Abstract: Diaminopimelic acid is obtained by culturing a diaminopimelic acid-producing mutant strain derived from Bacillus subtilis in a carbohydrate-containing nutrient medium therefor under aerobic conditions and recovering the acid from the fermentation product, e.g. by use of a cation-exchange resin.  The mutant strain is generally an auxotrophic mutant and may be obtained from the parent strain by irradiation with X-rays or U.V. rays.  Mutant strains derived from the auxotrophic mutants can also be used. The fermentation is suitably carried out at 25-35 DEG  C. and at a pH of about 7.  The auxotrophic mutant strain should be capable of growth in a medium prepared by adding an amino acid and a nucleic acid base to a minimal medium suitable for culture of the parent strain.  In examples a medium comprising glucose, (NH4)2SO4, K2HPO4, MgSO47H2O, yeast extract and CaCO3 is used.

Title: Improvements in processes of manufacturing and recovering glutamic acid and its compounds
Filed: 1931-10-15
Abstract: Glutamic acid is produced by hydrolysis of vegetable or animal proteins such as gluten and casein, beet molasses and molasses residues by boiling with an alkaline medium having an alkalinity of about 3 to 7 per cent, expressed as NaOH.  In an example, Steffen's beet molasses residual liquor is concentrated to 1,34 specific gravity or more, and solid or aqueous caustic soda is added until the mix has a specific gravity about 1,34 and an alkalinity of about 3 to 7 per cent, preferably 6 to 7 per cent, the temperature being kept below 100 DEG  C.  The mixture is then heated, preferably in an autoclave, to 80-100 DEG  C. and cooled rapidly to prevent racemization of the d-glutamic acid. Concentrated or gaseous hydrochloric acid is then added to produce an acidity of about 2,5 to 4,5 per cent, preferably 3,5 per cent or pH = 4,5, and the solution is evaporated in vacuo to a specific gravity of 1,48 at 65 DEG  C. Hydrochloric acid is again added up to pH = 2,1, and the liquid is cooled to remove inorganic salts.  Strong caustic soda solution or preferably ammonia gas is then added to pH = 3,2 (the isoelectric point of glutamic acid), and the solution is allowed to stand to crystallize d-glutamic acid.  If it is desired to obtain the hydrochloride of the acid, the last step (addition of soda or ammonia) is omitted, and the solution is saturated with hydrochloric acid, when the hydrochloride crystallizes out.  The Specification as open to inspection under Sect. 91 states that the neutralization of the acid solution by ammonia described above is also applicable to acid solutions of glutamic acid derived from the acid hydrolysis of the initial material and to the purification of glutamic acid of any origin.  This subject-matter does not appear in the Specification as accepted.
