Title: Electrical equalizer circuit
IPC: H04L25/03
Filed: 1958-04-11
Abstract: 842,794. Attenuation and delay equalizers. WESTERN ELECTRIC CO. Inc. April 11, 1958 [April 16, 1957], No. 11583/58. Class 40(8). An attenuation or delay equalizer comprises a correctly-terminated delay line 9, a main transmission path 13 coupled to the centre of the delay line and one or more pairs, e.g. 11, 15 and 12, 14, of auxiliary paths connected between the main path and points of the delay line symmetrically spaced about the centre. The input signal is applied to terminal 3 and the output taken from terminal 4. The delay line may have lumped or distributed constants and is coupled to the main and auxiliary paths by means of directional couplers 21 to 25. A suitable directional coupler for use with co-axial lines is described in U.S.A. Specification 2,679,632. The couplers 21, 22, 24, 25 are arranged so that only a small amount of power is extracted from the delay line, the input and output being connected to conjugate pairs of terminals. The amplitude and sign of the signals coupled into the auxiliary paths is determined by resistors 45, 46, 48, 49 which are variable about a matching value for which no power is transferred to these paths. The connections of the matching resistor 47 and the signal path 13 to the directional coupler 23 are reversed as compared with the corresponding connections to the other couplers. Further directional couplers 35 to 38 are used to couple the auxiliary paths 11, 12, 14, 15 to the main path 13. These are arranged to prevent power being fed back to the delay line from the auxiliary paths. The pairs of paths 11, 15 and 12, 14 transmit leading and lagging echo signals which, if they are equal and of the same polarity, provide altenuation equalization when combined with the main signal. Delay equalization is obtained when the echos are equal but of opposite polarity. Inequality of the echo signals produces both delay and altenuation equalization. The number of pairs of auxiliary paths may be increased to provide a desired equalization characteristic. Distortion in the directional couplers may be corrected by equalizing circuits 17, 29, 30, 31, 32 and losses may be compensated by an amplifier 18. In a modification (Fig. 2, not shown) the variable resistors are associated with the directional couplers 35 to 38 instead of with the couplers 21, 22, 24, 25.

Title: A process for producing a reticulated sheet and a reticulated sheet produced in accordance with the process
IPC: B29C55/00
Filed: 1970-03-12
Abstract: 1293456 Reticulated films; laminates BREVETEAM SA 12 March 1970 [18 April 1969 29 April 1969 25 Oct 1969] 11865/70 Headings B5B and B5N Reticulated films and sheets are made from sheet webs which are shrinkable in at least one direction, and made from a thermoplastic high polymer organic synthetic material by forming substantially parallel rows of slits in the sheet, slits of adjacent parallel rows being offset and said slits being disposed at right-angles to the direction of shrinking of the sheet, and then subjecting the sheet to heat or solvent to effect a shrinking of the material web between the slits to a thickened form and to thus form netlike openings by opening of the slits. Specified materials include polyamides, polyolefins and polyvinyl chloride. Thus, as shown in Fig. 1, S indicates the slits, T and R the thickened ribs and F hexagonal openings in the film web shown by dotted lines formed by the shrinkage of the film web. The slit pattern may be such that rows of mutually offset slits are interspersed with rows of non-offset slits, the film web after the shrinkage step having an appearance such as that shown in Fig. 16, the region of the rows of non-offset slits remaining unopened. The slit ends of adjacent rows may overlap considerably, as shown in Fig. 4. The slit patterns may differ considerably (Figs. 5 to 15, not shown) and may include patterns in which the slits are curved. The film web may have a shrinkage direction parallel to the lengthwise direction of the slits in addition to that transverse to the lengthwise direction of the slits. The film web to be reticulated may be tubular, the slits may be formed in the web while it is in the flattened state and the web may subsequently be shrunk while expanded to a tube form. Two or more layers of slit and shrinkable film web may be shrunk together, adjacent individual layers becoming bonded to one another whereby the assembly of film webs becomes converted into a laminated film or sheet. The shrinkable film web may be bonded to a non-textile covering or sheet and after the slitting and shrinking steps a further non-slit non-textile sheet may be bonded to the shrunk web. The bonding may be effected while the shrinkable web is still hot and plastic. The shrinkable film web may be bonded to a non- textile material web with a low shrinkability before the slitting step, the laminate being then slit and shrunk. The non-textile sheet may consist of a plastic, metal foil or paper. The opening of the reticulated film may be filled with an adhesive. The shrinkable film web may contain a foaming agent activated by the shrinking temperature. The shrinkable film web after the slitting step may be positioned between two non-textile layers and caused to shrink by application of heat while it is between the two layers.

Title: Improvements relating to the feeding of loose wooden nails or pegs to nailing or pegging machines
IPC: A43D71/00
Filed: 1937-04-26
Abstract: 482,551. Nailing. MUSENBICHLER, E. April 26, 1937, Nos. 11906 and 11907. Convention dates, April 25, 1936 and March 31, 1937. [Class 89 (iii)] Relates to apparatus for driving pre-formed, pointed, wooden pegs or nails into shoe parts, and consists in means for assorting the loose .pegs and feeding them point first to the driving mechanism. The pegs are fed from a hopper 1, Fig. 1, to a tray 4 which comprises a sloping surface 5 and three rings 6, 8, 9 each formed with holes 7 slightly larger than the crosssection of a peg 10, Fig. 4. The ring 9 is very slightly offset angularly with respect to the ring 8. Suitable mechanism is provided for imparting to the hopper and tray a vertical vibration of small amplitude and an intermittent rotary motion. Any peg which engages a hole in the ring 6 with its point will readily assume a vertical position and pass through the aligned holes in the rings 8, 9 to be supported on a non-rotary plate 11. A peg engaging a hole with its blunt end will not readily pass through the hole. If it does, it is arrested by the ring 9, due to the offsetting of this ring. Preferably, a stop member 29 is arranged above each hole in the ring 6, to assist in preventing a misplaced peg from assuming a vertical position, Fig. 4. As the tray 4 rotates, the pegs which have passed through all the rings 6, 8, 9 are brought in succession over a hole 12 in the plate 11, and fall into one of a series of holes 13 in a rotary or reciprocating member 14, whereby they are carried to the peg tube 15 of the driving mechanism. The pegs are assisted down the tube by puffs of air supplied by a tube 19. In a modification, Fig. 5, the loose pegs receive a preliminary assorting in a hopper 45, which has concentric, inclined, perforated surfaces 47a-47c and which separately receives vibrating and rotary motions. The pegs fall into. guide channels 35 in a curved member 34 which deliver to rings 32a-32c which are similar to the rings 6, 8, 9 and which, together with the member 34 and a member 37, receive vibrating and intermittent rotary motions. Pegs in the channels 35 are controlled by flexible members 38 carried by the member 37, and a stop member 36 acting similarly to the stops 29 is carried by a bracket 41 which, together with the peg-supporting plate 39, vibrates without rotation. According to the Specification as open to inspection under Sect. 91, the means for feeding pegs from the assorting mechanism may be dispensed with. This subject-matter does not appear in the Specification as accepted.

Title: Process for producing sliced veneer
IPC: B27B1/00
Filed: 1974-03-18
Abstract: 1469276 Forms of wood SADASHIGE FANCY PLYWOOD INDUSTRIES CO Ltd 18 March 1974 [17 Sept 1973 3 Oct 1973 30 Oct 1973 26 Nov 1973 28 Nov 1973 12 Dec 1973 15 Dec 1973] 11980/74 Addition to 1412903 Heading B5L A process for producing wood veneer comprises providing a plurality of individual flitches, e.g. a, b, c, d, e, f, Fig. 5, of log material, smoothing the surfaces of the flitches which are subsequently to be glued, applying a hydrophilic adhesive to the smoothed surfaces, gluing the flitches at the adhesive-bearing surfaces to form a composite flitch, as shown, and slicing said composite flitch to a desired thickness to produce a veneer, all the process being carried out while maintaining the moisture content of the wood flitches above the fibre saturation point. As described the flitches are produced by sawing or slicing a log lengthwise and transversely in various ways, or by cutting a log to have a prismatic section, e.g. as in Fig. 58, and adding pieces to give the flitch a generally square section.  The flitches are joined by hydrophilic adhesive which may be an underwater curing polyurethane adhesive and/or a moisture curing epoxy resin though other thermosetting and thermoplastics resins are specified. The adhesive may include a dye or pigment, e.g. alizarine red S, methylene blue, Sudan II, azo type dyestuff, cyanine type dyestuff, titanium white, red iron oxide, or chrome yellow. When a die is used it may diffuse into the flitches by capillary attraction.  The veneers may be united to form plywood, or adhered to a substrate of wood, plywood, hardboard, paper, plastics sheet, cement board, ceramic tiles, or metallic sheet, by hot pressing using an adhesive such as phenolic, resorcinol, urea, melamine, epoxy, unsaturated polyester, polyurethane or diallylphthalate resin, PVA, polymethylmethacrylate, polystyrene, polyvinyl acetal, polyvinyl butyral, methylcyanoacrylate nylon, polyacetal, ethylene/vinyl acetate copolymer, vinyl acetate emulsion, ureavinylacetate emulsion, styrene-butadiene rubber, nitrile rubber, polychloroprene, polybutadiene, polyisobutylene, polyisoprene-isobutylene, Thiokol (Registered Trade Mark), or polyacrylate resin. The flitches may have different shrinkage coefficients and be arranged in sub groups within the composite flitch so that all the sub groups have the same average shrinkage. When the flitches are of different woods flitches of wood which splits easily such as kalopruax, ash, zelkova, teak, elm, kokko, or red oak may be at least partially surrounded by flitches of woods which do not split easily such as saperre, moabi, American walnut, dao, rose wood, birch, and camphor tree. One or both faces of a flitch, Fig. 36, may have a groove 10 cut therein by a router. The groove may subsequently be filled with a thermosetting or thermoplastics resin, which may include a pigment or dye to provide an ornamental line in the veneer.
