Title: Improvements in or relating to tube conveyor systems
IPC: B65G51/44
Filed: 1929-03-18
Abstract: 308,175. Mix & Genest Akt.-Cres. March 16, 1928, [Convention date]. Electrically operated by vehicles.-In a tube conveyer system, in order to control operations such as the setting of junctions, the travelling containers are adapted to discharge spark gaps, the resulting voltage impulses being employed to carry out the operation. The tube L of a section of tube conveyer is formed with a short length J of insulating material, fitted with ring electrodes A, B to form a spark gap fed from a source of high tension. The distance between the electrodes A, B is such that normally no spark can pass. The travelling container P is formed with adjustable rings C, C<1> electrically connected together by a bridge M. As the container passes over the electrodes A, B it is stated that a spark passes when the distance between the electrodes A, B substantially equals the distance between the rings C, C<1>. The distance between the rings C, C<1> is adjustable to give selection. The operation to be performed is effected through a relay R or through an impulse lengthener comprising a thermionic tube E or a glow-lamp. In order that the spark generator G may not be in continuous operation, a contact K in the tube L is adapted, on passage of the container, to energize a time relay Z so that the generator is operated only just prior to the transit of the container. After operation, the generator is automatically switched off by the time relay Z. In a modified construction, the container P is formed with a number of fixed rings instead of with adjustable rings C, C<1>, and a rotary switch on the container base is adapted to connect up any ring with any other to alter the effective length of the spark gap.

IPC: A23L3/3409
Filed: 1936-03-30
Abstract: Citrus fruits, e.g. oranges, are preserved by exposure to low concentrations of diphenyl in the vapour phase.  The diphenyl may be introduced into the atmosphere of the chambers in which the fruit are stored, the composition of the atmosphere being also controlled, if desired, in respect of its oxygen, nitrogen or carbon dioxide content and in respect of its temperature.  The diphenyl may be vaporized into the fruit storage chambers. Alternatively, or in addition, the diphenyl may be applied to wrappers, containers or other solid media with which the fruit may come into contact or are enclosed in their packing or storage, the diphenyl being applied, if desired, with diluents, e.g. dissolved in mineral oil or paraffin wax or other waxy or oleaginous material.  The Provisional Specification also describes the use of derivatives of diphenyl including the phenolic and carboxylic derivatives such as the o-, m-, and p-phenyl phenols and the corresponding carboxylic acids and the halogenated derivatives of these compounds or of diphenyl.  The storage of eggs in flats treated with o-phenyl phenol or its sodium salt or with paraffin wax containing 7 per cent of o-phenyl phenol, or grapes enclosed in wrappers impregnated with o-phenyl phenol, and the dusting on of diphenyl or its derivatives over seed potatoes or other seed material not intended for human consumption is described.

Filed: 1945-04-16
Abstract: 595,159. Drying sand &c. by draining. PHILLIPS, N. April 16, 1945, No. 9522. [Class 34 (ii)] [Also in Group XXX] In a method of draining washed sand or the like, a number of galvanized sheet steel units 1 of arched or similar form are disposed on the ground where a pile 7 is to be set up, either as separate units or secured together to constitute a tunnel as in Fig. 1. The water draining through the pile to the structures 1 is deflected thereby into channels 1b which carry it away, the structures preferably being slightly inclined to ensure this. When sufficiently drained, dry sand may be loaded into a lorry, driven under the tunnel, through one or more gate-controlled discharge openings (not shown). As shown in Fig. 7 each unit may be mounted on a pair of wheels 8 running on rails 9 with a drainage channel 10 between them, and the structures may then be moved as necessary as the pile grows.

Title: Process for the production of materials having properties which contain lignocellulose
IPC: C08G18/72
Filed: 1972-03-01
Abstract: 1387454 Forms of wood; laminates BAYER AG 1 March 1972 [2 March 1971] 9531/72 Headings B5L and B5N [Also in Divisions C3 and D1] Lignocellulose-containing material is produced by bonding or impregnating lignocellulose with a mixture of aromatic polyisocyanates containing 15-35% by weight of isocyanate groups, the mixture comprising from 5-100% by weight of the residue which is obtained from the distillation under mild conditions (e.g. 100-160 C.) of a crude tolylene diisocyanate isomer mixture. This residue has a maximum carbodiimide group content of 1À4% by weight, and an average molecular weight of less than 1000 when mixed with 20% by weight of pure tolylene diisocyanate. The crude isomer mixture is that obtained from the reaction of isomeric mixtures of diaminotoluene with phosgene. The residue may be mixed with other aromatic polyisocyanates, e.g. 2,4- or 2,6-diisocyanatotoluene, 4,4-diisocyano-diphenyl methane or a polyphenylpolymethylene polyisocyanate and may be dissolved in an inert solvent, e.g. a hydrocarbon, ketone, ester nitrile, substituted acid amide, sulphone or sulphoxide. In Example 8, beech veneers are sprayed on all sides with a solution of the residue, polyphenylpolymethylene polyisocyanate, acetone and dimethylformamide. After evaporation of the solvent, 5 veneers are stacked on top of each other with the fibres in adjacent layers rotated through 90 degrees with respect to each other. The stack is united into a veneer panel by heat and pressure. In Example 9 birch veneers are treated on both sides with a solution of a similar residue and the same additives as in Example 8, the solution being applied by rollers. After evaporation of the solvent, the rolled veneers stacked together with untreated birch veneers and united into a panel by heat and pressure. In Example 12, mosaic parquetry bars which have been impregnated with a solution of the residue and polyphenylpolymethylene polyisocyanate in an inert solvent mixture are bonded to a chip panel made according to one of Examples 7-7 (see Division C3) by means of a polyurethane adhesive.
