Title: Improvements in or relating to heat insulating transparent double-walled panels moreparticularly for the walls and doors of refrigerators and cold storage rooms
IPC: F25D23/06
Filed: 1930-12-18
Abstract: 363,825. Refrigerators. LOVELL, G. and LOVELL, G. D., 10, Marshgate Lane, Stratford, London. Dec. 18, 1930, No. 38201. [Class 29.] A heat-insulating transparent d o u b 1 e - walled panel, particularly intended for the doors and walls of refrigerators or cold storage rooms, comprises a metal frame and two or more glass plates, and the glass plates are provided with metal rims which are soldered to the metal frame. An airtight joint is thus formed which prevents moisture from entering the space between the plates and the deposition of frost on their inner surfaces. In order to attach the metal rim, a glass plate 1 is first sand-blasted on its edge portions 2, 3, 4 and rendered electrically conductive on the roughened parts by silvering or by covering with graphite. A metal coating 5 is then deposited electrolytically on the edge to any desired thickness, and this coating enables the glass plate to be soldered to the metal frame.

Title: Holographic apparatus
IPC: G01B11/24
Filed: 1974-09-04
Abstract: 1486449 Holography K VOCKENHUBER and R HAUSER 4 Sept 1974 [4 Sept 1973] 38599/74 Heading G2J Apparatus for use in holographic interferometry comprises, referring to Fig. 2, a source L of coherent light; a beam-splitter 4 giving rise to an object beam 1 and a reference beam 2; a first lens 11 for focusing the object beam 1 at a first point A lying between lens 11 and the object C and a second lens O, having an aperture stop centred on Q, for focusing the reflected object beam 1' on to the receiver 6 where it interferes with the reference beam 2. The apparatus is characterized by the first point A, or its conjugate, lying in or near the centre Q of the aperture stop of lens O so that rays to and from the object are substantially parallel. In Fig. 2, point A and the centre Q of the aperture cannot be made to coincide for practical reasons; in Fig. 3, however, this is achieved by focusing the object beam 1 at a point A which is coincident with the centre of aperture stop P and which lies on a partially reflecting mirror M through which the light reflected by the object C passes. The reference beam 2 is also brought to a focus at this point. In Fig. 4 (not shown) the object beam does not pass through lens O before reaching the object, as it does in Fig. 3. In Figs. 5 and 5A (not shown)the point of focus of the reflected object beam and the point of focus of the reference beam lie between the receiver and the lens O. In Fig. 6 (not shown) the point A lies on a semireflective mirror between lens O and object C. In Fig. 7 (not shown) the point of focus of the reference beam 2 is reflected so that its image lies within the aperture stop of the lens O. The receiver may be the screen 6 of a T.V. camera tube 7.

Title: Improvements in moulds for printing surfaces and processes for producing such moulds
IPC: B41N11/00
Filed: 1929-10-18
Abstract: Moulds for producing printing surfaces, which may be used for casting stereo or other type metal or for the production of rubber stamps or dies, are made from a mixture of a synthetic resinous condensation product such as phenol-, urea-, or thiourea-formaldehyde condensation product and graphite and, if desired, other fillers such as cellulose, ground paper, wood meal, asbestos, mica and china clay. The mixture may be applied as a fine powder to the surface to be reproduced and pressed and heated or it may be previously made into plates of semi-cured material and the imprint made and the curing completed.  The latter process is specially suitable for making a mould from type bars.

Abstract: 1528927 Optical apparatus D M HUMPHREYS 22 Sept 1975 [25 Sept 1974] 38833/75 Heading G2J A 3-dimensional visual effect is produced by viewing a 2-dimensional picture 1 (which contains, in combination, the information which would be presented to each of the eyes of an observer of the original scene shown in the picture) via a refracting or reflecting element 2 having a Fresnel structure of parallel or concentric "ribs" 4, so that each eye of a person so viewing sees information having a correspondence with what that eye would have seen in viewing the original scene directly. The 2-d picture may be a photograph taken using a camera having a lens with a diameter of 65 to 70 mm, i.e. a typical interocular distance. It is stated that the astigmatic distortion of the Fresnel element introduces symmetrical modifications of the image perceived by each eye of a viewer. Isolating means 5 (absorbant or reflective) may be provided between the "ribs" 4 of the Fresnel lens.

Title: 5-carboxy-2,4-oxazolidinediones and derivatives thereof
IPC: C07F3/00
Filed: 1965-09-14
Abstract: The invention comprises magnesium chelates of 5 - carboxy - 2,4 - oxazolidinediones of the Formula B <FORM:1119047/C2/1> where R111 is an alkali metal, a substituted or unsubstituted hydrocarbyl radical or an -MgO-alkyl radical, and 2,4-oxazolidinediones of the Formula A <FORM:1119047/C2/2> where R is hydrogen or a substituted or unsubstituted hydrocarbyl radical and X is an -OR1 or -NHR11 radical where R1 is hydrogen or a substituted or unsubstituted hydrocarbyl radical and R11 is a substituted or unsubstituted hydrocarbyl radical.  The magnesium chelates are prepared by reacting a dione of the formula <FORM:1119047/C2/3> where R is as defined above, or is an alkali metal, with a magnesium alkyl carbonate in a solvent for the dione and the magnesium chelate. The derivatives of the Formula A are obtained by reacting the magnesium chelate B with a mineral acid, or an alcohol in the presence of a mineral acid, or a pyrocarbonate ester or with an organic isocyanate and, if necessary, subjecting the product to acid hydrolysis.  The magnesium chelates may also react with acylating agents, e.g. acid halides, or organic halides, to yield the 5-acyl or 5-hydrocarbyl-substituted oxazolidine derivatives respectively.  The 5-hydrocarbyl derivatives may be subjected to hydrolysis to give the corresponding a -hydroxy carboxylic acids and amines; this hydrolysis may be effected in two stages, the first stage yielding the urethane of the a -hydroxy carboxylic acid. Examples relate to the preparation of the novel compounds and derivatives thereof.  The magnesium alkyl carbonates can be prepared by reacting a magnesium alkoxide, obtained from Mg metal and an alkali metal alkoxide, with carbon dioxide.

Abstract: 1531539 Effecting scanning by moving apertures TELETYPE CORP 22 Sept 1976 [14 Oct 1975] 39399/76 Heading G2J A linear scan is produced by the conjunction of a spiral slit 88 in a first rotating member with a stationary longitudinal slit 80 in a second stationary member and one of a plurality of spiral slits 90, 92, 94, 96 in a second rotating member. The aperture is defined by aperture 80 in conjunction with one of the spirals 90-96, the spiral slit 88 merely serving to select which of the spirals 90-96 is used. By appropriate selection of the relative speeds of the first and second rotating members relative to the number of spirals on the second rotating member, the identity of which of the slits 90-96 is used is changed once per revolution of the first rotating member. Each spiral of the second rotating member may be composed of a plurality of contiguous concentric arc segments of equal angular subtense, the arrangement being such that the locus of their mid points forms an Archimedian spiral. Respective indexing marks 81 may correspond to each segment. The device is employed in a fax encoder wherein a line is projected on to the inventive aperture whereby the line may be scanned on to a detector while the marks 81 provide synchronizing pulses.
