Patent GB-2474518-A (GB)
Title: Identifying Associated Objects
Inventor: NAYLOR MICHAEL
IPC: G06K7/10
Filed: 2009-10-19
Abstract: Associated objects are identified using a sensor for sensing one or more parameters and/or change(s) in parameter(s) associated with a first object. An identification signal generator generates an identification signal for identifying a first object which comprises data indicative of the identity of the first object and data indicative of the parameter(s) and/or change(s) in parameter(s) associated with the first object sensed by the sensor. A transmitter transmits the signal which is received by a receiver. The signal is processed to determine a correlation of the data indicative of the parameter(s) and/or change(s) in parameter(s) associated with the first object with data indicative of parameter(s) and/or change(s) in parameter(s) associated with one or more further objects. An indication of associated objects is generated based on the correlation of the data indicative of the parameter(s) and/or the change(s) in parameter(s) associated with the objects. Objects moving together, e.g. in cargo containers, can therefore be grouped. RFID tags and readers may be used as identifying signal generators and receivers.

Title: Improvements relating to the production of keratin meal for use in moulding operations
IPC: C08L89/00
Filed: 1945-04-23
Abstract: Keratin is prepared for use in moulding compositions by crushing the raw material such as hoofs or horns and then subjecting the product to a selective grinding and sifting process in which the impurities are largely removed with the particles which pass through the finer meshes of the sieves while the coarser particles of keratin of a higher degree of purity are separated and subjected to a further stage of grinding.  The raw material may be submitted to a preliminary purification which comprises washing, drying for 24-36 hours at 80-90 DEG  C. and cooling.  The crushing which is preferably effected in a hammer mill, is followed by grinding in pin mills firstly at 2,000-3,000 revolutions per minute and finally at 4,000-6,000 revolutions per minute as a result of which the ash content is reduced from 2.5 to 0.2 per cent.  The purified product may be bleached by steeping for 6-24 hours in dilute ammonia solution, removing the aqueous liquor by centrifuging, rendering acid by iron-free hydrochloric acid and then adding the sodium salt of formaldehyde sulphoxylic acid with or without sodium hyposulphite with stirring.  The bleached material may be washed and dried at 45-50 DEG  C.  The p  purified product may be incorporated with phenol-formaldehyde resins or with urea- or melamine-formaldehyde condensation products and moulded at 145-160 DEG  C. at a pressure of 1-1 1/2 tons per square inch.ALSO:Keratin is prepared for use in moulding compositions by crushing the raw material such as hoofs or horns and then subjecting the product to a selective grinding and sifting process in which the impurities are largely removed with the particles which pass through the finer meshes of the sieves while the coarser particles of keratin of a higher degree of purity are separated and subjected to a further stage of grinding.

Title: Improvements in the manufacture of carboxylic acid anhydrides
IPC: C07C51/56
Filed: 1928-04-05
Abstract: 288,549. Consortium f³r Elektrochemische Industrie Ges. April 11, 1927, [Convention date]. Acetaldehyde; ethyldene diacetate.-Carboxylic acid anhydrides are prepared by reaction between an aliphatic or aromatic vinyl ester and a carboxylic acid, preferably by heating together in presence of a catalyst such as sulphuric, phosphoric, benzene-sulphonic, sulpho-acetic or other acid, an acid salt or a neutral salt such as mercury sulphate. Acetaldehyde formed in the reaction may be separated by distillation. The reaction may be carried out by passing the vapours of the components over a heated surface. In an example, vinyl acetate and acetic acid are boiled together with a small quantity of sulphuric acid. When no more acetaldehyde is produced, the mixture is distilled and acetic anhydride is separated from unchanged vinyl acetate and from ethylidene diacetate bv fractional distillation. The process may be rendered continuous by running the mixture into a column still from which acetaldehyde distils continuously and the anhydride is withdrawn at another point. Mixed anhydrides may be prepared, such as acetopropionic anhydride from vinyl acetate and propionic acid and butyroacetic anhydride from vinyl butyrate and acetic acid. The reaction may be carried out under increased or reduced pressures and in presence of indifferent gases, solvents, diluents &c.
