Title: Thermally conditioning hot materials in sheet-like form
IPC: C03B27/048
Filed: 1971-07-09
Abstract: 1402545 Annealing glass PILKINGTON BROS Ltd D C WRIGHT K N HARDCASTLE and P A BRERETON 6 July 1972 [9 July 1971] 32453/71 Heading C1M A method of annealing glass in sheet or ribbon form comprises advancing the glass, initially near to a temperature at the upper end of the annealing range so that one or both faces are presented to radiation absorbing surfaces maintained at a temperature at which there is a nett absorption of radiation from the glass, developing at least one zone of hot gas flow against the or both faces of the glass, the gas being heated to a temperature above the surface temperature of the glass whereby the gas supplies heat to the glass faces and regulating the heat transfer between the glass faces and the hot gas and thereby the temperature gradient existing through the thickness of the glass as it is annealed. The glass ribbon may be supported either on rollers or a cushion of gas, disposed between zones of hot gas and radiation absorbing surfaces. The zones of hot gas form opposed gas cushions, the lower cushion also supporting the glass ribbon. The zones of hot gas provide a progressively lower temperature in the direction of advance of the glass and may also provide a changing degree of heat transfer across the width of the glass. As shown, the hot gases are provided by opposed units 23, 24, each comprising a water jacket 25, the space 28 of which has inlet and outlet pipes 29, 30 for passage of water and the wall 26 of jacket 25 faces the glass ribbon (22). The jacket 25 is maintained at a temperature less than 100 C. A plenum chamber 37 for hot gas supplied through a pipe 38, is spaced from jacket 25 by spacers 36 and has nozzles 31 leading to a plurality of open-ended passageways 32 which pass through apertures 33 in water jacket 25, leaving a space 34 which leads back to the space 35 between chamber 37 and jacket 25 and which may be exhausted if desired.

Title: Method of making sequin-impregnated paper
IPC: D21F1/02
Filed: 1962-08-24
Abstract: A fancy tissue paper in which variously shaped sequins of anodized and dyed aluminium foil are distributed over the area of the paper is prepared by adding a mixture of sequins and water to the stuff in the headbox of a Fourdrinier machine and discharging the mixture via the slice on to the moving wire.  A cylinder-type machine may be used but a Fourdrinier machine is preferred since it is found that the sequins then tend to settle nearer to the upper surface of the web with consequently improved appearance. The sequins used are approximately of the same thickness as the tissue paper itself and may range in size from 1/32 inch to 3/16 inch.  The headbox concentration is stated to be 99.7% to 99.95% water, 0.05 to 0.3% fibres and less than 0.03% sequins.

IPC: B60Q1/14
Filed: 1920-11-18
Abstract: 176,068. Robinson, J., and Reid, G. H. Nov. 18,1920. Lantern shutters and screens. - The illuminating effect of vehicle head-lights is controlled by an apparatus such as a selenium cell or an electrooptical device which is responsive to the light from the head-lights of another vehicle proceeding in the opposite direction. The selenium cell 0, mounted on the dashboard or other part of the vehicle, is connected in series with a battery B<1> and the operating-winding of a relay S, the armature of which is connected to one pole of the main battery B operating the head-lights L. The fixed contact S<1> is connected directly to the lamps, the contact S<2> being also connected thereto through a resistance R. When the cell 0 is exposed to strong light the armature of the relay engages the contact S<2>, causing the current from the battery B to pass through the resistance R and thus dimming the light. The cell 0 may be provided with a shutter O<1> to cover the cell O during the day. In a modification, the cell may operate a switch arrangement to control the current to the lamps or may operate a shutter or screen in the lamp. If the device is used with an acetylene lamp, the relay S controls an electromagnet which operates the fuel-supply cock. If a dynamo having a shunt field winding is employed for supplying current to the lamps, the relay may operate to remove the short circuit from a resistance in series with the shunt winding.

Title: Process for the production of ketene, acetic anhydride, acetic acid and homologues thereof
IPC: C07C51/56
Filed: 1939-12-21
Abstract: 537,480. Aliphatic acids anhydrides and ketenes. DREYFUS, H. Dec. 21, 1939, No. 32641. Addition to 490,544. [Class 2 (iii)] Acetic acid and anhydride, ketene and their homologues are made by the reaction of carbon monoxide in aliphatic alcohols in the presence of a phosphorus oxyacid together with a basic nitrogen compound not combined with the acid. The nitrogen compound may even be added to the products issuing from the reaction zone, this being preferable if, as may be the case, a basic nitrogen compound is combined with a part of the phosphoric acid as described in the parent Specification. The catalyst may be phosphoric acid or a compound liberating it such as an alkyl phosphate. Suitable nitrogen compounds are ammonia, alkylamines, tetra-alkylammonium bases and aryl bases such as aniline, pyridine and quinoline ; also derivatives of carbamic acid and glycine such as urea, urethanes, glycinamide, glycine esters and N-alkyl derivatives of these bodies and acidylated basic derivatives of amino-carboxylic acids. The process may be effected at 250‹- 450‹C. and at reduced, normal or increased pressure, for instance 50-400 atmospheres or more. Traces of copper or silver compounds assist the reaction so that copper apparatus is suitable, and it may be silver-plated over all or a part of the surface ; or the apparatus may be lined with inert material such as gold. Water vapour may be present, this favouring the production of acetic acid, any methyl acetate and dimethyl ether in the product may be returned to the process, additional water vapour then being supplied. As acetic anhydride and ketene are formed, they may be separated from the products ; for instance acetic anhydride and acetic acid may be fractionally condensed, the ketene then being srubbed out of the remaining gases with acetone or acetic acid ; a liquid forming an azeotropic mixture with water such as benzene, toluene, xylene or chlorbenzene may then be advantageously employed. Alternatively the anhydride may be condensed in a liquid immiscible with water such as benzene or chloroform. In examples, methyl alcohol and carbon monoxide are reacted in the presence of (1) phosphoric acid and ethylamine which are sprayed into the mixture entering a copperreaction tube ; (2) ammonium phosphate, a solution of which is taken up by the mixture entering the reaction tube, while ammonia is added to the products leaving the reaction tube ; in this case the products are mixed with an excess of benzene vapour, cooled to 110‹C. to condense anhydride, cooled to room temperature to condense acetic acid, with some methyl acetate and dimethyl ether, and then scrubbed with acetic acid to absorb the ketene, yielding more anhydride.

The supply of gaseous fuel to a main heater is automatically maintained in constant proportion to that supplied to a dummy heater the temperature of which is maintained constant by automatic control of its fuel supply. In Fig. 1 gaseous fuel in a conduit 1 is supplied through valves 4a, 4b to oven burners 3a, 3b, respectively. The fuel supply pressure to each burner is automatically controlled by pressure gauges 23a, 23b controlling valves 4a, 4b through regulators 5a, 5b respectively. The gaseous fuel is also supplied through a conduit 6 to a test burner 11 and the rise in temperature of air supplied to this burner from a conduit 12 is measured by thermocouples 14, 15. This rise in temperature, which is a measure of the heat output of the test burner is arranged to control a valve 8 in conduit 6 and thereby maintain the heat output of the test burner constant. Flow of fuel through conduit 6 is then a measure of the calorific value of the gas and a flow meter 9 is arranged to control regulators 5a, 5b so that the oven fuel pressures are adjusted to maintain constant heat input to the ovens despite changes in calorific value. A liquid heat exchanger may, alternatively, be associated with the test burner to measure its heat output. In a modification valve 8 is additionally controlled in accordance with fuel flow through conduit 6.
