Patent GB-765566-A (GB)
Title: Artificial flavouring substances and their preparation
Inventor: MORTON IAN DOUGLAS
Filed: 1954-01-04
Abstract: A honey-flavoured product is made by reacting at elevated temperature a monosaccharide, especially glucose, with b -phenylalanine, tyrosine, or a salt or ester, e.g. ethyl ester, thereof in the presence of water at least five times the weight of amino compound, and the proportion of monosaccharide to amino compound being at least equimolar, preferably 1.8-2.5:1.  The mixture is preferably refluxed with vigorous stirring at or near the boiling point.  A polysaccharide yielding a monosaccharide under the reaction conditions may be used.  The progress of the reaction may be followed by fluorescence observations in ultra-violet light, the heating being stopped when the fluorescence is at or near its most intense green. The product may be freeze-dried to a powder.  It is preferably allowed to age, for two days at least, before being used for flavouring.  An example of artificial honey preparation is concerned with adding the product to water, sucrose, fructose and glucose, together with citric or tartaric acid and L-glutamic acid for enhancement of the honey flavour.  Specification 448,813 is referred to.

Title: Method and apparatus for producing glass fibers
IPC: C03B37/02
Filed: 1963-01-09
Abstract: <PICT:0978965/C1/1> <PICT:0978965/C1/2> In a method for drawing glass fibres from orifices in a bushing, cones of glass formed between the orifices and the drawn fibres are cooled by supporting a liquid with a surface directly exposed to the cones, the liquid being passed transversely to and spaced from the orifices.  As shown in Fig. 3, molten glass is fed from a furnace to a heated bushing 12 with orifices 14 from which it flows as cones of glass 18 that are drawn into fibres 16.  Acid etched stainless steel wires 100 are supported between alternate rows of cones 18 by a header 102. The wires 100 pass through passages 104 into the header 102 and are fed with cooling water from a supply conduit 106.  The water forms a film 108 round each wire 100 and travels along the length of the wires 100 and discharges into a trough 110.  In another embodiment the cooling motor is supported by shallow narrow troughs which are fed with water by a header to which they are attached and which overflow at their far ends into a collecting trough.  In a further embodiment, Fig. 8, the water support takes the form of an endless belt or strand 300 of metallic or non-metallic fabric passing around pulleys 306 between alternate rows of cones 18 and through a body of water 302 in a supply trough 304.  Ethylene glycol or ethylene diamine may be used to replace water as the cooling fluid.  The drawn fibres are gathered into a strand, size is applied and the strand is wound on a forming tube.  U.S.A.

Filed: 1992-09-03
Abstract: A printing apparatus has an array of cartridges (40,41,42) for printing a web (2) of e.g. paper passing through the array, and one or more units (48,49) containing printing medium. The cartridges (40,41,42) each are capable of transferring the printing medium from the units(s) (48,49) to the web (2). The unit(s) (48,49) and the cartridges (40,41,42) of the array are relatively movable, to allow the unit(s) (48,49) to interact successively with at least two of the cartridges (40,41,42). In this way it is possible to change printing from one cartridge (40,41,42) to another, allowing changes to be made to what is printed, without halting the movement of web (2) significantly. The present invention also proposes that the cartridges (40,41,42) may have printing cylinders (43,44,45,46) of different sizes, and furthermore that a mobile unwind stand may be used to move web material to the printing apparatus, and the web output from the printing apparatus processed by sheet folding techniques.

Filed: 1983-01-06
Abstract: PURPOSE:To improve properties of polypropylene PTP formed piecs such as tablet capsules etc. by heating a sheet on a sheet heating zone of a blister pack forming machine and forming it at a specific sheet temperature. CONSTITUTION:On a sheet heating zone of a blister pack forming machine, a sheet is heated and formed at polypropylene sheet temperature of 130-160 deg.C. When a PP sheet is formed at the forming temperature of 130 deg.C or lower, a formed piece obtained is a defective one where the formed shape of PTP is not transferred from the mold with good fidelity. When it is formed at 160 deg.C or higher, the sheet sticks to a platen or a heating roll, etc., incapable of being fed and formed. The forming temperature range of the sheet to obtain good PTP formed pieces from PP sheet is limited to 130-160 deg.C and preferably 135- 155 deg.C. When a preheating zone is added in front of the heating zone of the PTP forming machine, the total heating time of 5-15sec can perform steady production.
