Filed: 1970-05-08
Abstract: 1305971 Continuous bulk polymerization DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 8 May 1970 [8 May 1969] 22327/70 Heading C3P Substituted or unsubstituted vinyl compounds or mixtures thereof, are continuously polymerized in bulk in the presence of an initiator and the absence of oxygen by continuously introducing in a feed zone, a polymerization mixture into a continuously moving sheath of flexible material (e.g. synthetic plastics, or impregnated fabric) which lies flat in the feed zone, and slopes steeply downward in the direction of movement to substantially exclude air from the filled sheath and is formed continuously either from two separate webs of the flexible material which are guided together so that they lie flat on top of each other, or from a single web of the said material which is folded along its centre line or along two lines parallel to its centre line, in the vicinity of the feed zone so that two portions of said web lying flat, one on top of the other, are formed, the polymerization mixture being introduced between the two webs or web portions and the open, longitudinally extending edge or edges of the web or webs being brought together without permanent bonding and bent upwards by guide means to form a sheath which acts as the polymerization vessel, in such a way that the X-section of the sheath has a substantially U, L or inverted T shape, and the filled sheath is continuously guided substantially horizontally through a polymerization zone. The polymerization mixture may comprise a solution of polymer in the same or different monomer(s), or is preferably a prepolymer syrup. The mixture may also contain other agents such as an expanding agent, regulators, fillers, dyes, stabilizers, plasticizers &c. The initiator may be added with the mixture or separately, or the inner surfaces of the sheath may be impregnated with the initiator. The edges of the web or webs may be coated with a soft adhesive, and the polymerization zone may be followed by a tempering zone. After polymerization the sheath is removed by unbending and rolling the web or webs on to rollers. The web or webs may be a continuous band. Examples describe the polymerization of methyl methacrylate/butyl acrylate, methyl methacrylate, and styrene/acrylonitrile.

Title: Flexible gastroscope
IPC: A61B1/273
Filed: 1959-06-30
Abstract: 880,639. Gastroscopes. TSEPELER, J. A., WILLIAM-WILLMONT, M. N., SLAVIN, I. A., ROSENFELD, E. B., and USHAKOV, B. I. June 30, 1959, No. 22370/59. Class 81 (2). A gastroscope with a flexible stem is made to bend in one plane only, but the tip carrying the objective is made rotatable, both movements being effected by controls placed at the proximal end, adjacent to the eyepiece. The distal end of the flexible stem is connected, through wires 7, to racks 8, 8 at the proximal end, so that, by rotating a gear-wheel 9, one is pulled while the other is pushed, with consequent movement of the stem. For rotating the distal end, a tubular head 15, enclosing the objective lens and prism, is connected through gearing 14, 13 and a flexible rod 12 to a wheel 16, adjacent to the eyepiece. Rotation of this wheel consequently causes a corresponding change in the field of view. The transmission of light rays through the stem is accomplished by internally reflecting prisms. Specification 296,512 is referred to.

Title: Improvements in means and method for preventing and removing scale and incrustation in steam boilers
IPC: C02F1/48
Filed: 1925-09-08
Abstract: 264,551. Neeley, G. S., and Watkins, G. Sept. 8, 1925. Incrustation, preventing and removing.-Incrustation and scale in steam boilers is prevented and removed by applying an alternating current at points of greatest thermal difference. An insulated electrode 17 is arranged near the water line, and contact is made to it and to the lowest point of the boiler shell. One or more such electrodes may be employed, and one or more contacts made with the boiler in large units. The electrode may be longitudinally arranged in a steam drum, and is supported horizontally by a cable 18 and insulator 19. When the current is supplied from a lighting circuit, a lamp 25 may be interposed to reduce the voltage actually applied to the boiler to 2 volts. The lamp acts also as a low-water indicator. When applied to a locomotive boiler, the insulators 19 are secured to clamps which are attached to smoke tubes. The application to a condenser is also described. In the case of large boiler units, a step-down transformer may be used to increase the current available. Reference has been directed by the Comptroller to Specifications 3749/87, 6105/92, and 147,528.

Title: Improvements relating to the recovery of volatile substances in freeze drying processes
IPC: F26B5/06
Filed: 1963-06-07
Abstract: 1,030,000. Freeze drying. LEYBOLDHOCHVAKUUM - ANLAGEN G.m.b.H. June 7, 1963 [June 7, 1962], No. 22746/63. Heading F4G. [Also in Division B1] Volatile substances which together with moisture are driven out of material undergoing a vacuum drying process are contacted and retained in or by at least one cooled liquid and thereafter recovered from the liquid. The volatile substances may be retained by condensation and/or absorption or adsorption and/or chemical reaction. In Fig. 1, a freezedrying chamber 1 has a heated supporting surface 11 on which is the material 12 to be dried. This chamber communicates with condenser 2 having heat exchanger 22 cooled by refrigerating machine 21 which machine also cools a liquid, e.g. silicone oil, at 4 which subsequently enters the condenser 2 at nozzle 31. The liquid then runs down exchanger 22, and out through valve 34 into vessel 33 which may conveniently be a centrifuge to remove ice from the liquid phase. Pump 32 then recirculates the liquid whilst through valve 51 at least a part of the liquid can be withdrawn into pipe system 52 and passed to heat exchanger 6 where the volatile substances are removed from the liquid, condensed at 7 and subsequently discharged through valve 74 to collecting vessel 75. The liquid thus regenerated is returned to pipe 3 by pump 62. Vacuum pumps 81 and 82 are associated with freeze drying plant and the regeneration plant respectively. In an alternative embodiment (Fig. 2, not shown), the heat exchanger 22 may be dispensed with if the cooled liquid entering at 31 offers sufficient condensing area without needing to be further cooled. In another embodiment (Fig. 2, not shown), the condenser 2 is preceded by a condenser wherein water vapour is condensed on to a heat exchanger and subsequently discharged after thawing. A third condenser stage is added after condenser 2 which is similar in construction to the second condenser stage but acts as a hydrolyser for the volatile substances, e.g. ethereal oils, by circulating an alkaline solution, e.g. KOH with subsequent recovering of the reaction product and introduction of fresh caustic solution in a separating and refilling device. Oils and organic solvents which have a high vapour pressure at room temperature may also be used. Different non- aqueous volatile substances may be removed by different kinds of physico-chemical absorbers. The cooled liquid may also act as a vehicle for the transportation of ion exchanges and other adsorbents, e.g. active C.
