Title: Rolling Mill with Supported Working Rolls for the Elongation of Materials.
Inventor: ARNOLD KRIWAN
IPC: B21B27/03
Filed: 1916-10-30
Abstract: 102,057. Kriwan, A. June 3, 1915, [Convention date]. Rolling; tapering by rolling.-In a rolling-mill, the working rolls a are made of small diameter and are supported by relatively large rings b rotating on axles d. In the case of a three-high mill, the middle roll is supported by collars on the outer rolls. The rings b may be in the same vertical line as the rolls a, or two sets of rings may be arranged laterally of each roll. In the case of a one-way mill, only one set of rings may be arranged laterally of each roll. The axles d may be adjusted vertically by a wedge i and horizontally by screws g, and the rings may be eccentric to obtain various thicknesses in the work in one pass. The rolls may be cooled by a cooling-agent which enters a recess l in the bearing of one roll, passes into a channel n inside the roll, and thence in a similar way into and through the other roll.
Patent GB-728562-A (GB)
Title: Apparatus for separating liquids by thermal diffusion
Inventor: JONES ARTHUR LETCHER
IPC: B01D17/00
Filed: 1953-06-04
Abstract: In apparatus for separating liquids by thermal diffusion in which the liquid is passed through a narrow slit between opposed smooth equidistantly spaced faces of two liquid-impervious walls maintained at different temperatures, the faces of the walls are prevented from touching by providing between the faces spacers in the form of pieces of wire secured to or engaging with at least one of the walls.  The wires should be impervious and inert to the liquid being separated, and may be made by glass, metal, or plastic.  The spacers may be attached to the wall surfaces by welding, fusion, soldering, or brazing, or by means of lugs or screws; alternatively they may be held in place by frictional engagement with the surfaces.  A wire containing alternate pieces of different metals may be introduced between the surfaces and then one of the metals dissolved out.  As shown in Fig. 1, copper wire spacers 21 are provided in annular slit 22 formed between tubes 10, 11; the spacers are secured to the outside of tube 10 and arranged circumferentially round the tube at axial intervals along the tube.  The outer tube 11 is heated by a resistance wire coil 14.  The slit may be flat and may have a permeable membrane arranged between the wall faces, each of which is provided with spacers (Fig. 4, not shown).

Abstract: 479,094. Aircraft alighting - gear. FAUDI, F., (trading as FAUDI, F., [Firm of]). July 28, 1936, Nos. 15475/37 (divided out of 467,486 under which a Specification was laid open to inspection under Sect. 91 of the Acts, July 29, 1936) and 20114/37. [Class 4] In aircraft alighting-gear in which the wheels or other devices 3, Fig. 1, are carried at the lower ends of outwardly inclined shockabsorbing struts 1, of which the upper part 5 is pivoted to the aircraft at 6, the strut is guided to cause it to swing outward on the occurrence of a shock by means of an auxiliary strut 8, one end of which is pivoted to lower part 2 of strut 1 at a point 7 intermediate its ends and the other end pivoted to a point 10 on the aircraft lower than the point 6, the arrangement being such that the change in wheel track and wheel inclination on shock-absorber movement is relatively small. In order to increase the effective length of link 8, the link may be forked to embrace strut part 2 and is pivoted to a bracket extending outwardly from the strut, or the strut may be cranked as shown in Fig. 2. In a further modification, Fig. 3, the struts are pivoted to the aircraft body at points on that side of the plane of symmetry remote from the strut to which they are connected. The upper parts of the struts, and the links, may be enclosed within the body or body and wings of the aircraft as shown in Fig. 3. The alighting-gear is stated to be particularly suitable for rotating wing aircraft.

Title: Improvements relating to mirrors
IPC: C03C17/06
Filed: 1938-05-25
Abstract: 504,865. Mirrors. MIHALY, D. VON, BARDELEBEN, F., and BLANK, M. May 25, 1938, No. 15620. [Class 97 (i)] Flexible mirrors which are free from flaking or cracking of the silvered surface when the flexible carrier is bent, are obtained by applying the metal coating in the form of discontinuous particles by means of galvanic precipitation, spraying or cathodic dispersion. The carrier e.g. celluloid, the material known under the Registered Trade Mark " Cellophane," artificial horn, or synthetic resin, may be rendered conducting by rubbing with graphite or coating with a metal varnish when employing galvanic precipitation. The coating process is discontinued when the coating is sufficiently dense to act as a mirror, and is not carried on until a continuous coating is formed. Alternatively, a continuous coating may first be formed, and then treated chemically or mechanically, e.g. by sand-blasting, or spraying with an atomized solvent. The coating may be of silver or platinum, and may be protected by a coating of fish glue or isinglass, and an outer coating of varnish, celluloid, or synthetic resin. Either side of the metal coating may be used as the reflecting surface, or two mirrors may be connected back to back by an adhesive. The carrier may be provided with stiffening ribs or grooves, or with advertising matter on front or back. The carrier may be so shaped as to form a magnifying or reducing mirror, or composite mirrors, of plano-convex or like forms, may be made. Reference has been directed by the Comptroller to Specifications 271,611, [Class 97 (i)], and 440,006.
