Abstract: 973,675. Reflecting objectives. OPTISCHE INDUSTRIE DE OUDE DELFT N. V. Sept. 18, 1962 [Sept. 19, 1961], No. 35519/62. Heading G2J. Two facing concave mirrors are positioned so that light from an object strikes the mirror on the opposite side of the plane winding between the mirrors, this mirror reflects the light to the other mirror, and the latter forms an image of the object on the side of said central plane remote from the latter mirror. The span between the mirrors accommodates an obstruction to prevent light which has not been reflected by both mirrors from reaching the image. As shown in Fig. 1, light from object 2 strikes mirror 1 and is reflected thereby to mirror 3 which focuses an image at 4; 5 is the obstruction. Both mirrors may be apertured so that the object and image may each lie outside the span between the mirrors, but in this case it is preferred that the distance of the object from the mirror on which light therefrom is first incident shall not exceed 0. 25% the focal length of the other mirror. The mirrors may be aspherical or spherical, means being provided in the latter case to reduce spherical aberrations. Such means may comprise a plane parallel plate in the span between the mirrors and of a thickness more than 0. 40% the mean focal length of the mirrors. If desired, there may be a miniscus lens on each side of this plate and between the mirrors and the object or image a further plane parallel plate. Optical data are given in the Specification. Specification 471,365 is referred to.

Abstract: 1,193,967. Automatic control of hydrofoil craft. ELLIOTT BROS. (LONDON) Ltd. Sept. 7, 1967 [Aug. 10, 1966], No.35874/66. Heading G3R. In a system for automatically stabilizing a hydrofoil vehicle against heave and pitch, fore and aft hydrofoil surfaces are each controlled by predetermined combinations of shaped signals from heave responsive means mounted substantially at the centre of gravity of the vehicle and means responsive to pitch of the vehicle. To counter heave, pitch and roll of a hydrofoil vehicle, electrical signals from a vertical accelerometer mounted in the bow and from a vertical accelerometer and pitch and roll rate gyros mounted near the centre of gravity of the vehicle are suitably modified by resistance-capacity networks, amplified, and combined in various different senses and adjustable proportions to control four hydrofoils arranged in pairs at the bow and the stern. A method of determining the signal proportions required to achieve optimum stability is described. In a modification, trailing edge flaps associated with hydrofoils are controlled by the combination of signals from a vertical accelerometer and a pitch rate gyro mounted near the centre of gravity of the vehicle.

Title: Emulsion polymerization process and product thereof
IPC: C08F20/12
Filed: 1956-11-26
Abstract: Stable aqueous emulsions of polymers of C1-C10 alkyl acrylates and methacrylates are made by mixing water, the monomer and small proportions of sulphur dioxide and a tertiary alkyl aromatic hydroperoxide, e.g. cumene and diisopropyl benzene hydroperoxides, or paramenthane hydroperoxide to form a stable aqueous emulsion of monomer, adding a small proportion of a water-soluble polymerization catalyst, e.g. potassium, sodium and ammonium persulphates, and heating the mixture with continuous stirring to effect polymerization.  The sulphur dioxide and hydroperoxide react with the monomeric ester to produce a surface-active effect and the sulphur dioxide also acts as an initiator for the catalyst.  The monomeric ester may be copolymerized with a minor proportion of crotonic acid to yield an alkali-soluble copolymer.  A part of the monomeric material may be added to the reaction system after the start of polymerization.

Abstract: 863,622. Sealing package closures. STICKELBER & SON Inc.-Nov. 22, 1957, No. 36458/57. Class 94(1). [Also in Group XIII] In apparatus for cooling the seals of wrapped packages to which the sealed portions of the wrappers are moved in sliding engagement with a cooled metallic wall, the operative surface of the wall is provided with a covering of a synthetic resin which is non-adherent to the wrapping material. The apparatus shown in Figs. 1 and 2 comprises cooling units 10 for the end seals of waxed-paper wrappers enclosing loaves of bread, and a cooling unit 11 for their bottom seals, the units 10 being adjustable towards and away from each other to suit the length of the packages. The latter are conveyed through the apparatus by a lower endless belt 20 passing over driving rollers 21 and a supporting plate 19, and an upper endless belt 28 passing over driving roller 29, the upper belt being adjustable vertically according to the height of the packages. Each unit 10, Fig. 3, comprises a metallic front wall 42, a rear wall 43 and top and bottom walls 44, 45 forming a housing which encloses a coil 51 through which a cooling medium such as brine is circulated, the remaining space in the housing being filled with a heat-transfer medium 54. The outer face of the wall 42 is covered with synthetic resin 55, e.g. polytetrafluoroethylene, the covering consisting of a thin sheet bonded to the wall or being applied by spraying and subsequent baking. In a modification, Fig. 5, the units 10 are formed by rectangular tubular members 56 through which a cooling medium is circulated, the members being secured together so that their walls 58 constitute a flat surface which is covered with synthetic resin 55. The unit 11 is constructed in a similar manner. The use of the non-adherent covering makes it unnecessary to cool the operative surface of the units to such a temperature that ice is formed thereon.
