As shown, the part-cylindrical portion 1, and the lid portion 2 have welded, to their interior surfaces, at spaced locations along their lengths, crescentshaped stiffening members 3, 4 respectively which have pipe-line supporting pads 5, 6. The latter may be exteriorly lined with electrical insulating material, alternatively, an insulating band, e.g. of rubber, may be located around the pipe-line adjacent each reinforcing structure. In order to manufacture a sleeve the stiffening structures 3, 6 and 4, 5 are first welded, at the appropriate positions, within a whole cylindrical tube, comprised, e.g. of steel covered with bitumen material, after which the lid portion 2 is cut from the body portion 1. In order to mount the sleeve over a pipe-line, not shown, the body portion 1, with its opening lowermost, is placed over the pipe-line and is then rotated so that its opening is uppermost and the lid portion 2 can be lowered into position to close the opening. The lid portion 2 can be welded in position, the weld material being retained by strips 8, Fig. 3. A series of sleeves, welded end-to-end, may be provided along a pipe-line, a bend in the pipeline being negotiated by cutting a sleeve into angled segments arranged in "lobster back" configuration.

Abstract: 933,219. Producing ozone. M. OGAWA. Jan. 26, 1962, No. 3131/62. Class 39 (3). [Also in Group XXXV] In a medical ozone generating apparatus, Fig. 1, oxygen from a storage bottle 14 is fed by a magnetically operated valve 12 to a glass checkvalve mechanism 6, containing silicon oil 8, for preventing reverse-flow of ozone. The oxygen is then fed through a pipe 10 to an ozone generator 1 (Fig. 4, not shown) comprising an inner glass tube filled with neon, having electrodes 4, and an outer glass annular tube filled with ozone, having an electrode 5. The oxygen flows in the annular space between the tubes and is subjected to a corona discharge to produce ozone which is fed through a pipe 22 to a reservoir 18 pressurized by an hydraulic tank 25. A pressure chamber 30 is connected between the tank 25 and a mercury switch 35. The switch 35 is arranged as shown and at a predetermined pressure in the chamber 30 a mercury column 36a is in contact with a mercury column 39 so that a contact 41 is connected to a contact 40. In an electrical arrangement, Fig. 2, the mercury switch 35 when closed energizes a relay R from a supply through a switch 51. The relay R controls the energization of the magnetic valve 12, through a transformer T 2 , and a high-tension transformer T 3  for the ozone generator 1 by moving contacts 1 1 , 1 2  which isolate the transformers T 2 , T 3  when the relay is energized.

Patent GB-738184-A (GB)
Title: Improvements in or relating to process for the production of monoclinic glutamic acid crystals
Filed: 1953-02-09
Abstract: An improvement or modification of the process for the production of monoclinic glutamic acid crystals of the parent Specification, is characterized by admixing with an aqueous solution containing between 4 per cent and 40 per cent glutamic acid hydrochloride with vigorous agitation sufficient sodium hydroxide or monosodium glutamate to adjust the pH of said mixture to between 2.5 and 4.0, said aqueous solution containing from the commencement of the pH adjustment up to about thirty seconds after the completion of said adjustment at least one monoclinic glutamic acid crystal nucleus, said adjustment being completed prior to the formation of any orthorhombic crystals, and recovering monoclinic glutamic acid crystals from the resultant crystal containing slurry.  The monosodium glutamate and glutamic acid hydrochloride solutions employed may be prepared in any conventional manner from materials from which glutamic acid may be formed on hydrolysis such as animal and vegetable proteins and concentrated Steffen's filtrate and crude hydrolysate or prepared solutions may be employed in preparing the monoclinic glutamic acid. When seed crystals are employed they may be used in the form of a slurry or after separation from the mother liquor.  In the original production of seed crystals sodium hydroxide or a solution containing monosodium glutamate is added to a solution containing between about 4 and about 20 per cent of glutamic acid hydrochloride.  When solutions containing higher concentrations of glutamic acid hydrochloride are employed rapid stirring should be started as soon as crystallization of monoclinic crystals begins.  The solutions may be mixed at atmospheric or higher temperatures.  In a continuous process a slurry of monoclinic glutamic acid seed crystals in glutamic acid hydrochloride is prepared and rapidly agitated whilst glutamic acid hydrochloride solution and the solution which adjusts the pH of the mixture are added simultaneously and continuously.  The mixture may take place in a small container and the slurry may be continuously removed to a larger container to crystallize the monoclinic glutamic acid.  Batch processes may be operated.  In examples: monoclinic glutamic acid is obtained when aqueous sodium hydroxide solution is added to aqueous glutamic acid hydrochloride solution to adjust the pH to between 3.0 and 3.3 within three to five seconds (1); aqueous monosodium glutamate solution is employed in a similar process instead of sodium hydroxide solution (2); monoclinic glutamic acid is obtained by adding concentrated sodium hydroxide solution to aqueous glutamic acid hydrochloride to which monoclinic glutamic acid seed crystals have been added. Specification 653,264 is referred to.

Title: Steppless variable-stroke drive
IPC: F16H29/04
Filed: 1975-01-28
Abstract: 1464312 Variable-speed ratchet gear; eccentrics AVCO CORP 28 Jan 1975 3717/75 Headings F2D and F2K In an infinitely-variable-ratio drive between a sprocket 36 and a hub 70 in a bicycle, planet gears 100 are journalled in the hub, engage a fixed sun 82 and are rotated by shafts 64 through one-way clutches 102, the shafts 64 being each oscillated by a respective crank 62 having a follower roller 56 engaging an eccentric 44, which is rotated by the sprocket 36 and has variable eccentricity to vary the stroke of the cranks. The variable eccentric comprises inner and outer members 40, 44 respectively, the outer member 44 being rotatable on the inner member 40 by an amount limited by a pin 50 engaging in a slot 42 of the inner member 46. An end 61 of a spring 63 acts on an actuator 55, which has a radial slot 53 in which a tab 47 of member 44 engages, to bias the eccentric towards maximum eccentricity. The other end 65 of spring 63 is attached to a ring 69 which is movable against the action of a sprung arm 85 engaging notches 81, to vary the force of spring 63. In operation the reaction of the cranks 62, through follower rollers 56, against the eccentric 44 causes the eccentricity to vary against the spring bias and so the ratio automatically varies, and it is stated that this tends to maintain a constant input torque. Rapid variations of gear ratio are prevented by the filling of the groove 42 of inner eccentric member 40 with a viscous substance such as grease. The rollers 56 are kept in contact with eccentric 44 by a ring 57 in the embodiment illustrated, but this may be replaced by a separate spring in each shaft 64, biasing the cranks to maintain the rollers 56 in contact (Fig. 4, not shown). A member 79 driven by the sprocket 36 (through input member 26) may be provided with a ring gear which drives a flywheel to dampen out input torque fluctuations (Fig. 4, not shown). The hub is mounted in forks 14 and 16 of the bicycle, which forks support the reaction torque of the sun gear 82, which is fixed to a fixed spindle 12 on which the hub rotates. The eccentric illustrated has portions 49 and 51 of different radii of curvature, to give differing rates of change of transmission ratio depending on the eccentricity, and differing rates of pivoting of the cranks.
