Title: Tape transport system
IPC: G11B15/295
Filed: 1965-09-24
Abstract: 1,110,715. Feeding record tapes. MINNESOTA MINING & MANUFACTURING CO. 24 Sept., 1965 [28 Sept., 1964], No. 40816/65. Heading G5R. [Also in Divisions G3 and H2] A tape transport system comprises capstan 10 associated with solenoid-operated rollers 30, 34, the capstan being designed to drive leg 15 at a slightly higher speed than leg 16. Storage roller 36 is mounted on spring-biased lever 42 carrying brush 50 for potentiometer 52 which is connected to control unit 58 for reel motor 48. The motor is thus regulated to maintain the length of the storage loop substantially constant. A second storage roller 62 is similarly associated with reel motor 78. When auxiliary switch S2 is closed, main switch S1 starts and stops motors 12, 48, 78, in unison and simultaneously energizes or de-energizea solenoids 32, 35. Each of the reels 24, 28 functions as a supply reel or take-up reel in accordance with the position of the main switch. Only one capstan roller is used for rewinding the tape, a polarized relay R controlling solenoid 35 for this purpose. Switch S2 may be operated to allow the drive capstan 10 to be accelerated to full speed before the rollers 30, 34 are actuated to engage the tape. In another arrangement, main switch S1 is first adjusted to run the three motors in the desired direction and then auxiliary swtich S2 is actuated to start or stop the tape by controlling the solenoids 32, 35. When switch S1 is in its first position, positive voltage signals from potentiometer 52 increase the speed of supply reel 24 to lengthen the first storage loop, and positive signals from the potentiometer 75 increase the speed of take-up reel 28 to shorten the second storage loop. When the main switch is shifted to reverse the reel motors, reel 28 serves as supply reel and receives negative signals to accelerate when the second storage loop shortens, and reel 24 receives negative signals to accelerate when the first storage loop lengthens.

Abstract: 866,113. Feeding cards. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 8, 1959 [Dec. 8, 1958], No. 41691/59. Class 117 [Also in Group XVI] A card feeder (Fig. 2) includes a file feed 14 by which cards are fed via throat 38 to stack 18 in hopper 50 by means of friction rollers 40 driven from driving pulley 81. From stack 18 the cards are discharged singly through throat 52 by a pair of reciprocating pickers 56 for further processing. A joggler plate 54 is pivoted at 55 and oscillated against spring 64 by the cam 78 and bellcrank 72 so that the cards fed by rollers 40 to stack 18 are positioned laterally to aid discharge. Level device (Fig. 2). Normally when stack 18 is full, bellcrank 72 impinges upon screw 68 to swing plate 54 to the left, the plate swinging back till its projection 70 strikes (and joggles) the side of the stack. If, however, the level of the stack drops below projection 70, then plate 54 will swing to the right further than normal. This will cause screw 68 to swing bellcrank 72 anticlockwise to operate arm 88 to start the file feed 14. The stack 18 therefore rises again up to the projection 70. Card weight 32 (Fig. 3). The cards of feed 14 are pressed down by a card weight 32 which rests on top of the cards and is fed in its turn, by file feed 14 to stack 18 and is finally discharged by the operator through opening 110. The card weight is provided with lateral spring arms 100 by which it is guided as it moves forward, the arms retracting as the operator pulls the weight out through opening 100. Additionally, the weight carries on its underside a leaf-spring 90 to press the cards beneath it into close engagement with the discharge pickers 56.

The solutions may also contain a strongly basic agent and/or an organic solvent. The quantity of surfactant (b) required may be 2-40, preferably 5-20 times by weight the weight of dyestuff used.  The dye may first be dissolved in a strong aqueous solution of surfactant (b) and then the base and organic solvent may be added if required or alternatively the dye may first be dissolved in the base and organic solvent to which solution the surfactant is added.  A very large number of suitable cationic surfactants (b) are specified which fall into the following classes: fatty amines and derivatives and oxyethylation products thereof, preferably in the form of their salts, especially compounds of the formula <FORM:1007760/D1-D2/1> where R is an organic radical of at least 8C, R1, R2 and R3 are alkyl, aralkyl or aryl radicals which may be substituted or together with the N form a heterocycle and X is an anion; quaternary phosphonium compounds of the formula: <FORM:1007760/D1-D2/2> tertiary sulphonium compounds of the formula: <FORM:1007760/D1-D2/3> where the letters have the same meaning as before, as well as condensation products of fatty amines or their salts with up to 30 mols ethylene or propylene oxide.  It is preferred to use products whose pH is above 8.  The specified organic solvents are ethanol, butanol, ethyldiglycol, ethylthiodiglycol, polyethylene glycols of M.W. up to 500, dimethylformamide, phosphoric acid trisdimethylamide, acetone and dimethylsulphoxide.  The strong bases are preferably alkali metal hydroxides or ammonia. Suitable azo dyestuffs are known pigments containing the weakly acid groups, e.g. an hydroxyl bound to aromatic nuclei, carboxylic acid amide groups bound to or standing between aromatic nuclei, cyanuric acid amide groups, enolisable groups in acylacetyl compounds and pyrazolones or derivatives thereof and carboxylic acid amide groups in a heterocyclic ring.  The solutions may further contain polyethylene glycols of M.W. 150-20,000 as well as addition products of ethylene oxide with alcohols, fatty acids or alkyl phenols.  The solutions may be employed to dye or print leather, fibres, yarns, fabrics and fleeces of natural or regenerated cellulose, cellulose esters, wool, silk, polyamide, polyacrylonitrile, polyvinyl chloride and aromatic polyesters. When dyeing synthetic materials carriers may also be employed and when printing, alkali-resistant thickeners may also be employed. The dyed or printed material may be dried and then developed (i.e. the insoluble dye is precipitated) by treatment, preferably at room temperature, with an acid bath of pH 1-5 or with an excess of water.  White and coloured resists under the pad-dyeings of the invention may be prepared using a suitable acid resist agent. Examples are given.

Abstract: 946,316. Burners. AIR REDUCTION CO. Inc. Dec. 12, 1960 [Dec. 15, 1959], No. 42663/60. Heading F4T. A burner comprises a combustion chamber 36 closed at one end by a partition 20 through which pass a plurality of conduits 18 supplying oxygen, a plurality of conduits 19 supplying fuel gas and a conduit 56 supplying liquid fuel. The liquid fuel conduit 56 is at the centre of the partition and the gas and oxygen conduits are arranged in concentric circles. The spacing of the gas and oxygen conduits is not greater than twice the diameter of the conduits and not less than half the diameter of the conduits when the conduits have the same diameter and not greater than twice the greater diameter and not less than half the greater diameter when there is a difference in the conduit diameters. Low velocity flames are formed by eddy currents near the ends of the gas and oxygen conduits and anchor the higher velocity flames produced by the mixing of the main streams of oxygen and gas. The liquid fuel from the conduit 56 is atomized by the gas flames and burns there beyond. The length of the liquid fuel flame is increased by increasing the amount of gas so that the gas/oxygen flame contains products of combustion and a relatively low percentage of oxygen. The oxygen and gas conduits 18, 19 and the liquid fuel conduit 56 are secured at their forward ends in apertures in the partition 20; and the oxygen conduits 18 and the liquid fuel conduit 56 are also secured in apertures in a rearward partition 22. The assembly of conduits 18, 19, 56 and partitions 20, 22 is inserted into a housing 10 closed at its rear end by a threaded wall 12, carrying a perforated baffle 28 extending to the rear partition 22. Oxygen is supplied through two threaded openings 30 in the housing 10 behind the rear partition 22 and gas is supplied through a further threaded opening 32 in the housing ahead of the rear partition 22. The combustion chamber 36 is enclosed by a double walled sleeve 38 through which cooling water is circulated. The two walls of the sleeve 38 are screwed on to the housing 10 and are connected at their forward ends by a fitting 52 which is free to move relative to the outer wall.
