Title: Uniting surfaces with a cold setting glue
IPC: B27G11/00
Filed: 1942-10-01
Abstract: 562,953. Composite wood blocks; compound fabrics; electric heating. LAUCKS, Inc., I. F. Oct. 1, 1942, No. 13810. Convention date, April 9, 1942. [Class 145 (ii)] [Also in Groups VIII and XI] Relates to a method of uniting surfaces by means of a cold-setting adhesive whose rate of setting is accelerated by heat. According to the invention, the surfaces coated with adhesive are pressed tightly together, portions of the surfaces are caused to adhere by the application of heat, and the pressure is then released. The portions which were heated hold the surfaces in contact with one another while the remainder of the glue sets and causes adhesion of the surfaces. The method dispenses with the clamps usually employed to hold the surfaces together while cold-setting of the adhesive takes place. Suitable adhesives are animal glue, casein glue, or urea resin glue. The drawing illustrates the method of uniting two lengths of timber 1 by means of glue applied to the edges 2. The pieces 1 are pressed together by means of fluid-pressure cylinders 5, and heat is applied for a short time to a few spots along the edges 2 by means of electrodes 9. These may contain resistance heaters and apply radiant heat, but preferably they are connected to a generator 11 of high frequency electric oscillations. The electrodes are positioned above and below the edges 2, and the glue between the edges is heated by induction. The method may be used for uniting any surfaces which are adapted to be held together by clamps which only press together a minor part of the total surface area.

Title: Methods and apparatus for classifying names and like identifying marks
IPC: G06F17/30
Filed: 1974-03-29
Abstract: 1448397 Comparing words SOC DE DEPOT DE MARQUES 29 March 1974 [13 April 1973] 13916/74 Heading G4M A value, representing the degree of similarity between groups of symbols forming one or more words MP and groups of symbols forming other words MC, is calculated by (1) comparing pairs of words MPi, MCj to determine (a) the number l and L of symbols in the shorter and longer word of the pair; (b) the number a of symbols in the longest sequence (not necessarily continuous) common to both words and having similar symbols in the same positions in each word relative to the start of the sequence; (c) the number b of other symbols common to both words, and (d) the number c of symbols in the longer word not occurring in the shorter word; (2) using pairs of parameters (a, l), (b, L) and (c, L) table look up is performed on stored functions A, B and C which have slopes increasing with a, b, c respectively for constant l, L; and (3) deriving the value of (A+B-C) for the values of the functions selected. The invention is described as applied to identifying trade marks with which a proposed trade mark may conflict, the identified marks being printed out in order of degree of likely conflict. The derived value of (A+B-C) is preferably weighted by a factor D obtained by table lookup using the class and sub-class of the compared pair of marks MC and MP (i.e. goods or services to which the mark is or would be applied). Words may also be stored in the form of letters in alphabetical order each letter being associated with a number representing the number of times that letter occurs in the word. The difference between the number of occurrences of each letter in the longer word and those in the shorter word of a pair MPi, MCj may be summed (ignoring negative differences) to obtain c, from which a similarity parameter s = L - c can be found and then b = s - a. Again using table lookup with parameters s and the numbers l, L, a value for a similarity function S can be obtained and calculation of the risk of conflict inhibited if the S value is less than a minimum value S m . If, for a given word MPi, the risk of conflict function is calculated a given number of times, the value of S m  applied may be increased. The values of functions A-D may also be modified to take account of differences of pronunciation in different countries and the frequency of repetition of certain groups of letters common to the word pairs MPj, MCi.

Title: Improvements in the production of artificial filaments, threads, ribbons or the likeby dry spinning processes
IPC: D01F2/30
Filed: 1930-05-06
Abstract: Artificial filaments, ribbons, films, and the like are produced by dry spinning solutions of cellulose esters or ethers in solvent mixtures comprising a volatile substance or substances, a non-solvent liquid or liquids of higher boiling-point than the volatile substance or substances, and a solvent or solvents of higher boiling-point than the non-solvent liquid or liquids, the proportion of non-solvent to higher boiling solvent being between 3 : 1 and 1 : 3, and preferably between 2 : 1 and 1 : 2 by weight. The volatile substances, non-solvent liquids and higher boiling solvents may be those mentioned in the parent Specification, but preferably the non-solvent liquid is a substance containing one or more hydroxy groups, for example water, methyl, ethyl, or propyl alcohol, and the higher boiling solvent is diacetone alcohol, ethyl lactate, diethyl tartrate or diethyl phthalate. The non-solvent liquid may be present in quantity less than 12 per cent on the weight of the solvent mixture and the higher boiling solvent not exceeding 30 per cent on the weight of the cellulose ester or ether.  In carrying out the spinning process the temperature and the rate of flow of the evaporative medium may be adjusted to obtain any desired form (e.g. solid, hollow, &c.) or cross section of filament.  The spun filaments, which still contain higher boiling solvent may be drawn out, for example between two rollers rotating at different peripheral speeds. Specification 333,926, [Class 2 (ii), Cellulose &c.], is referred to.

Title: Improvements in or relating to processes for working up ores and metallurgical products of various kinds containing volatilisable metals
IPC: C22B5/16
Filed: 1927-05-24
Abstract: 287,745. Krupp Grusonwerk Akt.-Ges., F. May 24, 1927. Addition to 252,679. Roasting.-In a process of treating ores containing volatizable metals as claimed in the parent Specification, material such as lime, limestone, sand or saltpetre for stiffening the charge or for its further treatment is introduced into the reaction zone of the furnace. The addition of stiffening material allows the temperature of the reaction zone to be increased without causing fusion of the charge. The temperature can, however, be reduced by moistening the additions or by the decomposition of suitable additions. Fine ores which would tend to be carried away by the gases if introduced with the charge may also be introduced into the reaction zone, being preferably blown in with additional fuel. The coarser oxides obtained by the process may also be added for their further treatment.

Abstract: 434,676. Grinding. DESOUTTER BROS., Ltd., and DESOUTTER, C., 73, Baker Street, London, and WEBB, G. H., 123, Whitchurch Gardens, Whitchurch Lane, Edgware, Middlesex. May 9, 1934, No. 14030. [Class 60] [See also Groups XXII and XXVI] A rotary tool device which may be adopted for grinding having an air motor with radially slidable vanes carried in slots provided in an eccentrically arranged rotor, is characterized by the provision of a number of expansion chambers and at least one communicating passage, which is narrow but of comparatively large area, between two such adjacent chambers, thus providing for expansion of the exhaust air from the motor prior to its leaving the main casing. Compressed air passes to the hollow handle 48 through a trigger-operated valve 43 and thence along a passage 49, Fig. 4, to the crescent-shaped motor chamber 9 where the tangential jet of air impinges on the blades and rotates the rotor 11. The exhaust air passes out through a number of openings 24 into an expansion chamber 25 between the motor chamber and the outside casing, a flange 28 on the former provides a narrow space 27 of comparatively large area for the exhaust air to pass through on its way to the adjacent expansion chamber 26 and finally to the main outlet 29, this arrangement considerably reducing the noise due to exhaust air leaving the device. A sun pinion on the front end of the rotor shaft drives a tool connected to the cage 32 through planetary gears 30 carried by the cage which engage a fixed internally toothed annulus 37.

Abstract: 1,126,996. Intruder alarms. VANDALARM SECURITY SYSTEMS Inc. 28 March, 1967 [25 Aug., 1966], No. 14094/67. Heading G4N. An alarm system comprises two input signal channels 11, 12 each modulated on to a common, swept, carrier signal from oscillator 31. The resulting signals are fed via bandpass filters 27M, 27C to detectors 28M, 28C, the outputs from which are fed to an inhibit gate 14. The inputs to the two channels are derived from microphone 24M, 24C in the area to be protected. The microphone 24C is placed near a source of normal sound, e.g. a refrigerator, so that any sounds from this source picked up by microphone 24M are prevented from initiating an alarm. Sounds from an intruder are picked up only by microphone 24M and are passed by the gate circuit 14 to the alarm circuit 17-23. Details of this circuitry are described with reference to Fig. 3 (not shown) and include a capacitor (35) which is charged at a predetermined rate by pulse input signals, and at a slower rate by continuous tone signals until the voltage across it is sufficient to trigger Schmitt circuit 22 and initiate the alarm.
