Title: Classifying and control device
IPC: B07C5/28
Filed: 1952-03-24
Abstract: 707,809. Automatic. control systems. EXACT WEIGHT SCALE CO. March 24, 1952 [March 27, 1951], No. 7508/52. Drawings to Specification. Class 38(4) In a control system in which electronic means produce a voltage dependent on the deviation of a physical characteristic of each of a series of successive articles from a desired value, electronic control means responsive to the deviation voltage are arranged to effect control only when the deviation varies in a preselected manner in a number of the articles, and switching means are operated momentarily by each article to render the corresponding deviation voltage effective. The invention is applied to a beam-type weight checking machine of the type in which the weighing beam moves the plates of an electric condenser to vary the frequency of an oscillator combined with a discriminator circuit to produce a voltage dependent in magnitude and polarity on the magnitude and sense of deviation of the weight of each of a series of filled packages passing through the machine. The deviation voltage is utilized in a manner described below to control the filler spout of a dispenser from which the packages are filled before being transported on a conveyer to the weighing section of the machine. As each package leaves the weighing section of the machine a beam of light associated with a photo-electric cell is interrupted. Electromagnetic relays controlled by thermionic valves are energized or deenergized during this period in dependence on the sense of weight deviation, provided the latter exceeds preset values, to cause operation of one of two stepping switches. After a number of consecutive packages of the wrong weight, determined by the setting of manually set selector switches, a reversible electric motor runs in the appropriate direction to effect correcting adjustment of the filler spout. The operating time of the motor is limited by a time delay relay which also re-sets the 'stepping switches. A time delay relay prevents advance of the stepping switches while the correction motor is running. The number of successive packages of the wrong weight necessary before correction can take place may be for example 2, 3 or 4 and the number may depend on whether they are under or over-weight. Packages of the desired weight or packages having a weight deviation of the opposite sense which intervene in the series, cause resetting of the stepping switches. The correction motor may be operated in either direction by push buttons. Lamps indicate correct weight, underweight correction and overweight correction.

Title: Improvements in or relating to cross-linking polymers
IPC: C08J9/14
Filed: 1964-02-25
Abstract: A process for cross-linking and, if desired, expanding a polymer or copolymer of an epihalohydrin comprises heating a mixture of the polymer and from 0.5% to 10% by weight of a heat decomposable ammonium salt, based on the polymer, in a confined space under pressure at a temperature above the decomposition temperature of the ammonium salt.  For an expanded polymer, a blowing agent may be incorporated in the mixture, the heating being at a temperature above the decomposition temperature of the ammonium salt and the blowing agent to effect blowing and at least partial cross-linking of the polymer, thereafter releasing the pressure and subjecting the resulting polymer to a post cure at atmospheric pressure to complete the cross-linking.  The epihalohydrin polymers may be homopolymers or copolymers with alkylene oxides in which at least 50% by weight of the repeating units are derived from epihalohydrins.  Numerous examples of ammonium salts of both organic and inorganic acids are given. Those preferred decompose below 375 DEG  F. and in the case of ammonium carbonate, bicarbonate and carbamate these compounds may be used to cross-link and expand the polymer.  Both chemical and solvent blowing agents may be used to expand the polymers, e.g. azobis-(formamide), azobis-(isobutyronitrile), benzene sulphonyl hydrazide, p,p1-oxybis-(benzene sulphonyl hydrazide), hexane, chloroform, trichloro-ethylene and monochlorotrifluoromethane. The epihalohydrin polymers may initially be prepared by reacting the desired monomers in the presence of a catalyst formed by reacting an organo-aluminium compound with water and if desired a chelating agent such as acetylacetone, benzoylacetone, acetoacetic acid, ethyl glycolate, oxalic acid and glycoxal monoxime. The expanded cross-linked products may be used for mattresses, pillows, furniture padding, shockproof packing, thermal or sound insulation and for rigid and semi-rigid foam.

Title: Method of isolating caramel colour
Inventor: CLELAND JAMES E
IPC: A23G3/32
Filed: 1957-03-12
Abstract: Caramel is separated from a caramelized carbohydrate solution containing residual uncaramelized sugar and fermentation-inhibiting constituents formed in situ, by first removing the fermentation-inhibiting constituents, inoculating the solution with an organism or enzyme adapted to change the residual uncaramelized sugar to a chemically-different material, and separating this material from the caramel.  According to an example, 1000 gals. caramel colour was diluted with water to about 20 B<\>ae.  Water was then evaporated under a vacuum of 2611 until the B<\>ae increased to about 38 DEG  C.; the fermentation-inhibiting constituents passed off with the vapour and were thus removed from the caramel colour.  The caramel colour was again diluted to 20 B<\>ae with water and was inoculated with a culture of Aspergillus niger.  The citric acid produced was neutralized with lime to yield calcium citrate which was separated by decantation or filtration.  The mother liquor was adjusted to a pH of 2.5-3.0 and finally concentrated to about 50 per cent solids.  According to Examples 2 and 3, Saccharomyces cerecisiae and Bacterium putidum respectively were employed.  Specification 685,961 is referred to.
