Title: Improvements in or relating to the protection of electrical apparatus against voltage surges
IPC: H02H9/00
Filed: 1941-03-05
Abstract: 588,359. Protective arrangements. GENERAL ELECTRIC CO., Ltd., and FRIEDLANDER, E. S. March 5, 1941, No. 3010. Drawings to Specification. [Class 38 (iv)] In the protection of alternators, transformers and feeders against voltage surges by means of a number of pieces of two-conductor cable connected in parallel and constituting a capacity which is connected in series or in parallel With the apparatus, the pieces of cable have natural frequencies, no one of which is an integral multiple or sub-multiple of another. In this way, the development, by the surge, of well-defined and harmful frequencies (which may occur when equal lengths are chosen) is avoided. The pieces of cable may be similar, but of different lengths ; the lengths 2A, 3A, 5A, 7A, 9A, 11A are given as an example. Or the lengths may be the same and the dielectric material of the cable and/or the permeability of the material around the core may be different to give the same result. Cables of unequal lengthmay be bent into .the form of a number of concentric circles, their conductors at one end being connected to the line and at the other connected to one another, the sheathing being earthed.

[Classes 2 (ii), 2 (iii) and 15 (ii)] The dyeing properties of cellulose textile materials, e.g. their affinity for direct, sulphur, vat, azoic, basic, acid, chrome and cellulose acetate dyestuffs, are improved by incorporating therein a product obtained by the interaction of cyanamide, formaldehyde and at least one phenolic compound selected from the group phenol, pyrocatechol, resorcinol, hydroquinone, phloroglucinol, p-nitrophenol and salol. A dispersion of the product may be added to a solution from which textile threads are formed or the textile material may be impregnated with a solution containing the components of the product, e.g. a solution obtained by dissolving the phenolic compound in an aqueous solution of cyanamide, adding aqueous formaldehyde and adjusting the pH value of the solution to about 6.5, the impregnated material being hydro-extracted, and, preferably after being allowed to stand, dried below 100‹C. after the material has become alkaline and heated to render the condensation product insoluble in water. In examples, (1) regenerated cellulose staple fibre is treated for 10-minutes with a cold solution at a pH of 6.5, obtained by adding phenol to an aqueous cyanamide solution, heating for 1 hour at 80‹C., coding and adding aqueous formaldehyde and the treated fibre is hydro-extracted, dried below 100‹C. and heated for 15 minutes at 140‹C.; (2) regenerated cellulose staple fibre is treated for 10 minutes with a cold solution obtained by adding resorcinol to an aqueous cyanamide solution, then adding aqueous formaldehyde and sufficient caustic soda to adjust the pH to 6.5 and the treated fibre is hydro-extracted, dried and heated as in (1); (3) the fibre treated as in (1) or (2) is allowed to stand for 2 hours between the hydroextraction and the drying ; (4) to an aqueous solution containing cyanamide and resorcinol is added acqueous formaldehyde and sufficient caustic soda to adjust the pH to 10-11 and the precipitate is separated, dried, heated at 140‹C. and ground with water to a 20 per cent. paste which is diluted with glycerol to a 12 per cent solid content and injected into viscose as described in Specification 290,693, [Class 2 (ii)], the product is extruded into an acid ammonium sulphate bath as described in Specification 502,199, the resulting threads being washed and desulphurized.

Abstract: 1,027,776. Woodworking. W. SCHOCK. Jan. 28, 1963 [Feb. 2, 1962], No. 3402/63. Heading B5L. A method of manufacturing boarded panels 21 having a central layer in the form of corrugated wood veneer strip 9<SP>1</SP> having its grain extending perpendicularly to its length and to the boarding comprises continuously peeling a veneer strip of desired thickness from a freshly felled or steamed veneer trunk 1 and subdivided the strip into strips of desired width by cutting discs 10 which penetrate into the trunk and removing the surplus water from the strips by a dryer 18 while they are given a meandering shape. The cutting discs 10 penetrate the trunk before the strips are cut by a knife 4, the thickness of the strips being determined by a roller. The cut strips are fed by pairs of belts 13, 13<SP>1</SP> to a shaping device having a pair of chains 16<SP>1</SP>, 1611, each of which carries cooperating cells 151, 15<SP>11</SP>. The chains move the cells intermittently so that the cut strips form the shape shown in the cells and are then carried over a dryer 18 so that the shape of the strips is fixed. As the cells separate, the corrugated strips are directed by shoots 19 on to a base-plate 21 of a frame 20 reciprocated in the direction of the arrow. The length of strip in the frame may be increased by compressing the convolutions of the strip by a pusher. The baseplates may be covered with glue before the introduction of the strips and a glue-covered cover-plate may be pressed on to the whole after filling with the strip. In another embodiment, the strip is corrugated and dried by heated shaping rollers 25, 26.

Abstract: 793,107. Valves. BYRON, E., and TOPHAM, A. E. May 2, 1956 [Feb. 5, 1955], No. 3476/55. Class 135. The closure meinber 5, Fig. 6, which cooperates with the seat 4, is provided with a transversely arranged operating spindle 6, Fig. 2, embodying a cam 10, on each side of which is a cross-piece 13; the ends of the latter slidably engage studs 14 extending from the back of the member 5 whilst compression springs 15, Fig. 6, surround the studs. The cross-pieces 13 are of saddle form to enable the shaft 6 to rotate therein. The ends of the cross-pieces may be joined or formed to overlap to engage a common stud on each side of the spindle. The shaft 6 is rotated by a lever 9, Fig. 2, carrying a spring-loaded plunger 19 adapted to engage holes 20 in the valve body to index the open and closed position of the valve; the plunger head has a notch 25 coacting with a lug 24 on the spindle boss 23. When the plunger 19 is manually retracted and turned to hold it out of the holes 20 the valve may be actuated. The lug 24 may be bored to receive the link of a padlock. In operation, the first 90 degrees of spindle rotation places a flat part 12, Fig. 6, of the cam 10 against the back of the closure member so that the springs 15 act to draw the latter axially away from the seat 4; during the next 90 degrees of movement the closure member 5 is rotated with the spindle until it assumes the open position shown. A projection 17 on the member 5 prevents the latter being turned beyond the fully open position. The reverse operation of the spindle effects quick closing and positive seating of the closure member 5.

Abstract: 803,066. Lift trucks. SHARP, J. R., and KAYE, E. May 3,1955 [Feb. 8, 1954 ; Dec. 24, 1954], Nos. 3593/54 and 37341/54. Class 78 (3). In a lift truck the lifting carriage and movable guides are raised by a single pair of chains or cables each of which co-operates with pulleys mounted on the movable elements of a pair of oppositely-acting hydraulic rams. Rams 21, 25 (Fig. 3), are secured to the fixed guide 15 at 20, 24 and carry pairs of pulleys 23, 28, 29 which, together with pairs of pulleys 33, 34, mounted on the movable guide 16, co-operate with a pair of chains 30 which are anchored to the guide 15 and lifting carriage 17. In operation ram 21 is extended to raise the carriage nearly to the top of guide 16, whilst extension of ram 25 first moves the carriage into engagement with a stop 27 and then raises the guide through the carriage. An abutment 36 is provided to engage stop 27 to effect initial movement of guide 16. In a modification (Fig. 6) the original pulleys 33, 34 are dispensed with and a pair of pulleys 34 are journalled in a bracket secured to both the piston-rod or ram 25 and the guide 16. With this arrangement, both jacks are of the same effective crosssection and are connected in parallel to a common source of fluid pressure; the weight of section 16 and the forces exerted by chain 30 on the pulleys 23, 34 being such that on admission of fluid to the system ram 21 only extends until the carriage reaches the tops of guide 16, whereafter ram 25 extends, so simultaneously raising guide 16 and contracting ram 21. If desired, valves may be provided to connect the rams separately to the source of fluid pressure. Fig. 7 (not shown), illustrates a detailed construction of the arrangement shown in Fig. 6 which includes a horizontal ram adapted to tilt fork 18 relative to the carriage. Specification 780,487, [Group XXXI], is referred to.
