Title: Improvements in or relating to baking bread and the like
Inventor: PAUSEY ERNEST GILBERT
IPC: A21D8/06
Filed: 1963-01-14
Abstract: Bread loaves or rolls are baked by enclosing dough within a wrapper and manipulating the package so that the dough seals the wrapper e.g. by turning it over so that the dough rests on the folded over edges of the wrapper, carrying out a first proof, and then baking for the final proof e.g. for 45 to 55 minutes at a temperature within the range 415 DEG -425 DEG F.  Preferably the dough before the first proof occupies about one third of the space within the wrapper and after the first proof, about two thirds of that space.  The final third of the space is filled during baking. The wrapping material is preferably a transparent cellulose film capable of withstanding the baking temperature without softening, burning or discolouring, and which will form a tight sealed wrapper for the final loaf in which it will then keep for fourteen days or more.  The loaf can be sliced directly from the wrapper.  Suitable constituents for the dough include flour, fat, improver, water, gluten, salt and yeast.

Abstract: 1,178,273. Cathode-ray tube displays. GOSUDARSTVENNY NAUCHNO-ISSLEDOVATELSKYIPROEKTNYINSTITUTMETALLURGICHESKOI PROMYSHLENNOSTI. 11 Jan., 1967, No. 1531/67. Heading H4T. In an arrangement for deflecting beam of a cathode-ray tube to produce traces determined by code signals from a digital computer, the signals produced by the latter comprise (1), signals indicative of the trace configuration (i.e. whether straight line or curve, e.g. parabola or ellipse); (2) signals indicative of the X, Y co-ordinates of the mid-point of the trace and (3), signals indicative of the projection of the trace on the X, Y axes. Additionally, signals indicative of the thickness of the trace and of the beginning and end of arcs are also produced by the computer. Fig. 1 shows the general scheme in which the various code signals are supplied to a register 1. For producing straight line traces the mid-point signals Ax, Ay are converted to corresponding D.C. voltages in respective converters 10, 11 and the projection signals Px, Py are converted to corresponding A.C. signals in respective converters 12, 13. The latter are fed from an A.C. source 2, directly in the case of converter 12, and via one of the outputs of a phase shifter 5, one of AND gates 18-20 and OR gate 21, in the case of converter 13. The outputs of 10 and 12 and 11 and 13 are then combined in respective summing amplifiers 14, 15 and fed to the horizontal and vertical deflection plates of the display tube 16 the trace on which may be photographed by a camera 17. The particular phase of the output of shifter 5 which is utilized is determined by the configuration signal K which, via decoder 4 selects that one of the gates 18-20 supplied with the required phase which, in the case of tracing straight lines or ellipses, may be 0, 90 or 180 degrees. When parabolas are to be traced gate 22 is selected and passes to OR gate 21 the output of generator 2 after frequency doubling in 6 and 90 degrees phase shifting in 7. The thickness representative signal D is decoded in 3 and operates via a brightness control circuit 9 (detailed in Fig. 3, not shown) to control the beam intensity of tube 16 to ensure uniformity of trace brightness for traces of different thickness. The output of circuit 9 (which includes a gamma correction circuit) is supplied to the tube intensity control electrode via an AND gate 24 which has as a second input the output of a flip-flop 23 switched between its two states by signals from a circuit 8 (detailed in Fig. 2, not shown) termed an arc tracing unit, and which is controlled by signals 01, 02 indicative respectively of the beginning and end of arcs.

Title: Improvements in or relating to Methods of Bleaching and Dyeing Photographic Images.
IPC: G03C5/48
Filed: 1916-02-02
Abstract: 100,098. Brewster Film Corporation, (Assignees of Miller, H.). Feb. 26, 1915. [Convention date]. Colour photography; toning and after-treatment.-Coloured photographs are obtained by converting a silver image into a substantially invisible, colourless, transparent, dye-absorptive substance, which is thought to be a hydrosol or hydrogel of a silver salt and requires no fixing, and dyeing it; such images may be used for all forms of coloured photographic work or kinematography. The image is bleached by treating it with a solution of iodine in an iodide, preferably potassium iodide, or with a solution containing potassium iodide and potassium bichromate, permanganate or persulphate, or cerium permangar.ate or persulphate, or a similar substance which releases iodine from the potassium iodide. The solution may also contain acetic, hydriodic, nitric or formic acid. Suitable formulµ are (1) potassium iodide 5 grams, iodine, 0.15 grams, 3 per cent acetic acid 5 c.c., water to make 100 c.c., (2) potassium iodide 5 grams, potassium bichromate (1 per cent solution) 5 c.c. to 25 c.c., 3 per cent acetic acid 5 c.c. to 25 c.c., water to make 100 c.c. Considerable variation of the first of these formulµ may be made if the free iodine is present in the ratio of 1 per cent to 4 per cent of the potassium iodide, but higher concentration of the potassium iodide than 10 per cent is not advisable. The excess of iodine is removed from the treated image by a reducing agent such as sodium bisulphite, and the image, after washing, is dyed, preferably with a basic aniline dye in a slightly acid bath, and finally washed to remove excess dye. The dyeing-solution may be capable of giving an opaque or transparent image, and the film may be hardened with formalin &c. to ensure clear high-lights after dyeing. The silver image may be redeveloped if desired. Specifications 10258/07, 27818/09 and 25084/12 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) states also that the bleaching bath may comprise a solution of iodine or other halogen in an iodide or other haloid, or may be such as to convert the silver into a chromate, ferrocyanide or ferricyanide, and that the silver of the image may be removed after dyeing by .potassium cyanide or hypo. the dye being first fixed. This subject-matter does not appear in the Specification as accepted.

In an arc-welding electrode for depositing a weld metal comprising two or more alloying components, the alloying substances are applied next to a steel core in two or more radially successive layers surrounded by a slag forming and protective layer or layers, an alloying substance allotted to one of the inner layers having a different melting property from that of an alloying substance allotted to another inner layer. The innermost layer may contain ferrotungsten while the following layer may contain ferrochromium so that the tungsten which has a higher melting point than the chromium is in a zone of higher temperature while its losses due to burning are reduced since it is separated from the slag-forming layer. The layers are prepared from dry powder mixtures to which water glass is added to form a party mass for application by extrusion or a more liquid mass for application by dipping. To facilitate application, the inner layers may contain ground talc or steel powder and may also contain de-oxidizing and refining agents. The electrode may be used for welding joints or for applying an 18/8 stainless steel coating to a steel base or a high carbon content coating to a cast iron base.
