Title: Process for feeding an injection molding machine
Inventor: SAUERBRUCH ERNST
IPC: B29C31/06
Filed: 1987-09-30
Abstract: The plastic material, eg polyester, is fed into material containers (11) of a feed device and discharged into a feed cylinder (1). The closed airtight containers are brought to the feed device and automatically opened immediately before being discharged to the feed cylinder. In a particular embodiment, the full material container is brought, with the aid of a swivel frame (14), from an intake position into a discharge position by being pivoted 180 DEG . In the intake position the swivel frame is allocated a cover-removing device (22,26,27,30), by which both covers (28) placed on the front ends of the material container are automatically removed. Immediately thereafter the open material container is brought into the discharge position and the material is poured into the feed cylinder. Thus the time during which the material is exposed to harmful environmental influences in the open material container is extremely short. <IMAGE>
Patent GB-2210436-A (GB)
Title: Thermostatic flow control valve
Inventor: BELFIELD GEOFFREY
IPC: F16K17/38
Filed: 1987-10-01
Abstract: The thermostatic flow control valve operates at a predetermined and variable temperature to stop the flow of the medium through the flow control valve when the predetermined temperature is reached. The medium will only flow once it has cooled sufficiently to allow the contraction of a wax-bulb (6). This allows a spring (3) to lift a washer (4) off the valve seating. Some adjustment to the predetermined temperature can be made using an adjuster screw (8) or to a greater degree by varying the 'wax' mixture in the wax-bulb (6). The whole unit is designed to fit into standard pipework. <IMAGE>

Patent GB-887901-A (GB)
IPC: A23L29/281
Abstract: 887,901. Vitamin compositions. HOFFMANN-LA ROCHE & CO. A.G., F. April 11, 1960 [April 17, 1959], No. 12781/60. Class 81 (1). [Also in Groups III, IV (a) and IV (b)] Dry particulate products are obtained from gellable colloidal aqueous solutions, e.g. solutions of pectin, agar, tragacanth, alginates and gelatine, which may, if desired, contain additional materials such as vitamins, flavouring agents, colouring compositions and growth stimulants, by subdividing the solutions into fine droplets in a gaseous medium having a temperature at least 10‹ C. below the melting-point of the resulting gel, keeping the droplets separated for a time sufficient for gelling to begin and then drying the particles, which have gelled sufficiently and lost enough water to avoid agglomeration, to cause them to set permanently in gel form. Sub-division may be effected by spraying, atomizing, releasing through fine openings or by releasing a thin layer on a rotating plate, and the droplets may be gelled by falling through a still gas or through gas flowing in countercurrent to the falling droplets. Preferred duration of fall is at least 15 seconds over distances not less than 4 metres. The aqueous colloidal solutions may include a minor proportion, e.g. 10-30%, of an organic solvent, such as a lower aliphatic alcohol, e.g. ethanol, and may also include plasticizers, anti-oxidants, emulsifiers and preservatives, a number of each of which are specified. Air, nitrogen and carbon dioxide are specified gaseous media, the gas temperature being held at 10-20 C. below the melting-point of the resulting gel. Relative humidity in the gas should not exceed 30%. The drying of the gelled particles is effected preferably between 10‹ and 50‹ C., and the resistance of particles to water may be improved by treatment with a hardening agent, e.g. formaldehyde. Examples are given of the manufacture of particulate products from aqueous solutions containing: (1) gelatine, Vitamin A acetate, disodium ethylenediamine tetracetate, sugar, and butylated hydroxytoluene, with or without polyoxyethylene sorbitan mono-oleate; (2) gelatine, Vitamin A palmitate, invert sugar, butylated hydroxyanisole, propyl gallate, propyl phydroxybenzoate and #-phenoxyethyldimethyldodecyl ammonium bromide; and (3) gelatine, DL-α-tocopherol acetate, invert sugar, and #- phenoxyethyldimethyldodecyl ammonium bromide. Reference is made also to the preparation of carotenoid-containing products, e.g. products containing carotene, #-apo-8<SP>1</SP>-carotenal (C30), canthaxanthin, zeaxanthin, and lycopene, and products containing Vitamin B 1 , Vitamin C or panthenol.

Title: Process and plant for the treatment of high-strength ammoniacal liquors
Inventor: HAYWOOD STEPHEN PATRICK
IPC: C02F3/00
Filed: 1991-09-21
Abstract: A process and plant for purifying high-strength ammoniacal liquor, comprising aerating the liquor in a vessel (1) to effect biological nitrification, providing a source (6) of additional ammonia and dispensing same at a controlled rate into the liquor to maintain a substantially constant ammonia load on the body of liquor in the vessel, and subsequently discharging the nitrified liquor into a sedimentation chamber (9) from which settled sludge is redirected to the vessel (1) and product liquor is withdrawn (at 14). Temperature, pH and oxygen content within the vessel (1) are monitored and automatically controlled. The process achieves biological purification of high-strength ammoniacal liquors by nitrification in the activated sludge process, substantially or entirely without prior dilution of the liquor and by use of a compact plant, and with a substitute, synthetic source of ammonia to ensure that the plant continues to operate in a stable condition when the liquor supply is reduced or discontinued. <IMAGE>

Title: Power actuated releasable connector for pressure containing bores
Inventor: HOPPER HANS PAUL
IPC: F16L37/00
Filed: 1991-12-19
Abstract: A releasable connector for pressure containing bores, particularly connections used for subsea drilling and oil or gas production, has independent, powered actuating mechanisms for its locking and pre-loading functions. The locking may be effected by locking dogs 6, collet fingers or a spring ring cooperating with a groove, and the pre-loading by tension bolts 7. Both mechanisms may be operated hydraulically, the locking using a low and the pre-loading a high pressure. For locking, the connector is first locked and then pre-loaded, for unlocking, the preloading is released first, but the unlocking mechanism has sufficient power to release the lock even if the pre-loading release mechanism fails. <IMAGE>
