Title: Improvements in magnetic core storage apparatus
IPC: H03K19/16
Filed: 1959-07-03
Abstract: 908,444. Magnetic core matrices. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 3, 1959 [July 3, 1958], No. 22873/59. Class 106(1). [Also in Group XXXIX] Both the columns and rows of a magnetic core matrix have separate read-in and read-out lines on which half pulses are applied by column read-out generator 53, column read-in generator 50 and row pulse generators 55 and 56, serving the odd and even rows respectively. In a first instant of time information is read out of a selected core and at a second instant the information is re-recorded in the selected core or in another. As described the alternative core is that in the adjacent lower row, due to the connection of the read-out line of row n with the read-in line of row n-1, the read-out line of the bottom row of the matrix being connected with the read-in line of the top row. The column read-in and read-out lines are connected to earth through diodes e.g. 51 1 , 54 1  and a common transistor switch e.g. 52 1 . Normal scanning of, say, core 2 1  is effected as follows: in the first instant of time, read-out generator 53 and generator 55 each issue a half-read pulse while gates 511 and 1 are open, and the result is sensed by line 57; if the core stored a " 1," i.e. there is a signal on line 57, at the second instant of time read-in generator 50 and generator 56 each issue half-write pulses with gates 51 1  and 2 open resulting in " 1 " being rerecorded in core 2 1 . Shift scanning of the same core differs from the normal scanning in that at the second instant of time generators 50 and 55 supply the half-write pulses while gates 51 1  and 1 remain open. In the Specification are described the sequence of operations necessary for performing normal or shifted scanning on two columns of the matrix sequentially row-by-row e.g. normal scanning of column 1, shifted scanning of column 2, which is applicable in multiplication where the multiplicand is stored in column 1 and the successive partial products in column 2. The pulse generators are controlled by triggers (Fig. 3, not shown).

Filed: 1945-11-06
Abstract: 599,026. Knitting-machines. KANGOL WEAR CO., and HUBER, G. Nov. 6, 1945, No. 22954. [Class 74 (ii)] The needles C of a flat, single bed knitting machine are moved to knitting position by the front edge g of an oscillating or reciprocating bar G, acting through two-armed rocking members B, one arm b<1> of any of which is in the path of the edge g when the second arm b<2> thereof rests on the surface of an endless band, or on one of a series of flats E, passing over an intermittently rotated cylinder D. When the arm b<2> drops through an aperture in the band or flat, the member B is in an inoperative position, shown dotted ; and when the arm b2 drops part-way through a shorter aperture, Fig. 4, the arm b<1> is brought into the path of a second eye g<1>, and the corresponding needle so moved to a " half-needle " position. The arms b<2> may be lifted out of the apertures by suitably shaping their ends, or by a positively actuated bar or rod F. Three stepper cams on the face of a rotating wheel are, as usual, used to omit the first three needles, for forming the crown, at the commencement of each section of a beret or the like. These cams operate on a horizontally sliding finger which slides a plate on the end of the reciprocating or oscillating bar, to alter the effective length of the bar. According to the Provisional Specification, the needle at the end of a group may be moved to the " half-needle " position by means of a lateral projection secured to the upper arm of one member and co-acting with a recess in a corresponding position on the adjacent member.

Abstract: 1,242,864. Porous metal laminates. DUNLOP HOLDINGS Ltd. 13 May, 1969 [15 May, 1968], No. 23027/68. Heading B5N. [Also in Divisions B3, C7 and F2] An acoustic element comprises at least one surface layer including a plurality of apertures and at least one underlayer in the form of a three-dimensional network of intercommunicating cells and made substantially of metal. The underlayer may be made by spraying, dipping or electrodepositing metal, e.g. Ag, Cu, Fe, Ni and alloys on to a porous substrate, e.g. felt, sponge or foam, particularly a reticulated polyurethane foam. The substrate may then be removed by heating. The surface layer may be a woven or meshed plastics or metal material, or an open-cell construction, and should have a lower porosity than the underlayer. The layers may be separated by other porous layers or may be directly bonded. Bonding may be by adhesive or by welding. In one example, two foam layers of different porosities are superposed and made integral by depositing metal thereon, and are used as acoustic elements for covering silencers and jet engine exhausts.

Abstract: 350,317. Cellular elements for pressure responsive devices. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Eby, E. De W. ; 100, Holmes Road, Pittsfield, Massachusetts, U.S.A.) July 31, 1930, No. 23119. Convention date, July 31, 1929. [Classes 69 (i) and 135.] A cellular element for a pressure responsive device and particularly adapted for use in variable capacity reservoirs used to receive oil from high-tension underground electric cables, comprises a pair of discs united directly or indirectly at their peripheries to form a chamber, each disc having a central flat portion 18 and concentric corrugations 19 which increase in depth, radius of curvature and pitch towards their peripheries, the low portions of the corrugations on one disc being in concentric register with similar portions on the other disc so that when the discs occupy closely adjacent portions the low portions contact mutually to support the discs. In the form shown in Fig. 3 the discs are electrically welded to a channel-shaped ring 22, but in a modification the discs are reversed and welded together to enclose a volume of CO<2> or nitrogen under pressure. The discs are preferably made from the metal known under the registered Trade Mark " Momel," and the rings from bronze known under the registered Trade Mark " Everdur." Fig. 1 shows the invention applied to a breather reservoir for electric cables. A stack of cellular elements are secured between a pair of end plates by straps 28 and are arranged in a cylindrical tank 6 having a vent 16b with a downturned end. The tank is partly filled with oil through a fitting 17, the desired level being indicated on a gauge glass 16a.

Title: Improvements in or relating to polyphase asynchronous motors
IPC: H02K17/30
Filed: 1929-07-27
Abstract: 316,326. Siemens -- Schuckertwerke Akt.-Ges. July 28, 1928, [Convention date]. Addition to 299,886. Alternating-current induction machines.-In the starting apparatus for three-phase motors described in the parent Specification, a relay is provided through which flows the whole or part of the primary current and which in the normal position cuts out a starting resistance in one of the primary phases but re-introduces the resistance when the current exceeds a predetermined value. As shown, a relay 7 having reversing contacts 5, 6 is connected together with a starting resistance 8 in one of the primary phases of the motor 2. On closing the main switch 4, the large starting current energizes the relay and the armature is attracted to connect the resistance 8 in one of the phases. When the motor reaches full speed, the current drops to the normal value, and the relay 7 allows its armature to fall whereby the resistance 8 is cut out. According to the Specification as open to inspection under Sect. 91 (3) (a), starting resistances may be introduced in two of the primary phases. This subject-matter does not appear in the Specification as accepted.

Filed: 1956-07-27
Abstract: 828,819. Photo-electric control of photographic exposures. RABJOHN, P. G. July 23, 1957 [July 27, 1956], No. 23244/56. Class 40 (3). In a photographic enlarger in which the exposure time is controlled by a photo-cell which receives light passing through the negative and the printing paper, the switch contacts 27 of the enlarging lamp 28 are controlled by the circuit shown. Variable capacitors 231 are charged in accordance with the setting of a potentiometer 211 whilst a valve 221 draws grid current. To close the switch contacts 27, a double switch 191 is operated to connect the positive side of the capacitors 231 to the cathode of the valve 221 so as to cut off the anode current through the valve and cause the voltage across a resistance 241 and therefore the grid bias of valve 251 to become zero. The valve 251 then conducts and relay 261 for contacts 27 is operated until the capacitors 231 are sufficiently discharged at a rate determined by the photo-cell 29 for the valve 221 to become conducting again. Increase of voltage across the resistance 241 cuts off the valve 251, causing the contacts 27 to open. The printing paper is positioned on a translucent glass panel by pegs and clamped by a spring-raised pivoted mask, or by a separate mask engaged with the pegs. A modified circuit is described with reference to Fig. 1 (not shown).

Abstract: Guanidine alkyl aryl sulphonates of the general formula <FORM:0690439/IV (b)/1> in which R is an alkyl radical containing 6-18 carbon atoms, which may be straight or branched chain, and Ar is a benzene nucleus, which may be substituted by other groups such as lower alkyl groups, may be prepared by neutralizing the free alkyl aryl sulphonic acid with guanidine or commercial guanidine carbonate. Alternatively the sodium alkyl aryl sulphonate may be heated with guanidine sulphate, phosphate, carbonate or other salt.  The resultant pasty product may be spray- or drum-dried and the powder p so obtained used in detergent compositions (see Group III).ALSO:Guanidine alkyl aryl sulphonates of the general formula <FORM:0690439/III/1> in which R is an alkyl radical containing 6-18 carbon atoms, which may be straight or branched chain, and Ar is a benzene nucleus, which may be substituted by other groups such as lower alkyl groups, are incorporated in pulverulent detergent compositions. Sodium alkyl aryl sulphonates may also be present, and the tendency of these compounds to cake and become sticky is reduced by the presence of the guanidine alkyl aryl sulphonate. Preferably 7.5-50 per cent of the total sulphonate is guanidine sulphonate, though smaller amounts (down to 5.0 per cent) may be employed.  The pasty product obtained in the preparation of the guanidine alkyl aryl sulphonates (see Group IV(b)) may be spray- or drum-dried and the resultant powder used direct in the detergent compositions.  In preparing mixtures of sodium and guanidine alkyl aryl sulphonates, the two salts may be prepared separately and mixed before or after drying, or the free sulphonic acid may be neutralized by a mixture of guanidine and a neutralizing agent containing sodium.  Builders and diluents such as sodium sulphate, magnesium sulphate, guanidine sulphate, sodium chloride, alkali metal phosphates, silicates, borates and carbonates, starch, polyethylene glycols, polyvinyl alcohols and carboxy methyl cellulose may also be present. Compositions containing at least 25 per cent alkali pyrophosphate or polyphosphate (particularly tetrasodium pyrophosphate and pentasodium tripolyphosphate) may be prepared.  The total alkylaryl sulphonate content of the composition may be from 10-50 per cent, preferably 15-35 per cent.  In a typical example the following compositions are compared: (a) 35 per cent sodium polypropylene benzene sulphonate (C12-C15 alkyl), 25 per cent tetrasodium pyrophosphate, 30 per cent sodium sulphate, 10 per cent other materials and (b) 27.5 per cent sodium polypropylene benzene sulphonate, 7-5 per cent guanidine polypropylene benzene sulphonate, and the remainder as in (a).
