Title: Improved machine for swaging metal tubes
IPC: B21J7/16
Filed: 1951-07-26
Abstract: 694,472. Making tubes. GENERAL MOTORS CORPORATION. July 26, 1951 [July 28, 1950], No. 17710/51. Classes 83 (ii) and 83 (iv). Swaging.- A tube swaging machine comprises a mandrel and oppositely disposed dies which fit around the tube and means for recurrently striking the dies to produce a swaging or hammering action on the tube as it is drawn over the mandrel, the mandrel having its working surface relieved over alternate short zones along the length thereof. The machine has a hollow carrier 20 j journalled in a housing 21 and rotated by means of pulleys 22 and 23 driven by a motor 25 and belts 24. The housing has a tubular hub 27 which supports a circular row of rolls 26. The portion of the carrier 20 extending coaxially in the circular space defined by the rolls 26 has a diametral recess in which a pair of dies 31, 32 and die hammers 35 and 37 are slidably supported. The outer end of each hammer has a roller 36, 38 which is successively engaged by the rolls 26 as they are carried round by the rotating hub 27. The dies pound the external surface of the tube 33 as it is fed through the machine by two sets of rollers 50, 51. The rollers 50 are idle and the rollers 51 driven through bevel gears from the motor 25. A mandrel 40 is held in the pass between the dies by a rod 41. The input end of each die has a tapered lead 43 and the mandrel has a tapered outer end 42. The working surface of the mandrel has alternate full diameter zones A, C, E and G, and intermediate smaller diameter zones B, D and F. The zones A, C, E and G are 0.011 inches smaller in diameter than the inside of the tube and the zones B, D and F are 0.004 inches smaller in diameter than the zones A, C, E and G. In operation, the tube is inserted into the pass between the dies 31 and 32 and as the carrier 20 rotates the hammers 35 and 37 repeatedly pound the dies 31 and 32 against the tube wall. As the tube passes over the larger zones metal is displaced by the dies towards the relieved zones, resulting in a bur. nishing which provides a mirror-like internal surface to the tube.

Title: Process for producing on fibres of acetyl-cellulose or of linear polyamides or polyurethanes dyeings fast to cross-dyeing
IPC: D06P1/12
Filed: 1953-06-26
Abstract: Azoic dyeings, fast to cross-dyeing, are produced on acetyl cellulose, linear polyamide or polyurethane fibres by applying an aqueous medium containing a diazotizable amine of the formula: <FORM:0765740/IV(b)/1> in which the benzene nucleus may be further substituted by alkyl, alkoxy or halogen, X is -CO-, -CO2, -SO2- or -SO3-, and R is alkyl, aralkyl, aryl or hydroaromatic, and a coupling component comprising an alkali metal compound of an arylide of 2:3 hydroxy-naphthoic acid which contains in the arylide residue an alkoxy group either alone or together with further substituents such as halogen atoms or methyl or other alkoxy groups, effecting diazotization on the fibre and developing the dyestuff in a hot bath. In an example, cellulose acetate yarn is treated in an aqueous bath at 75 DEG C. containing 1-amino-2 - methoxybenzene - 5 - carboxylic acid - n-butyl ester, the sodium salt of 1-(21:31 - hodroxy - naphthoylamino) - 2 - methyl - 4 methoxybenzene, diethanolamine, sodium chloride, ammonia and the condensation product from oleic acid chloride and albumen decomposition products, preferably lysalbic acid according to Specification 413,016, diazotization is then effected with acidified sodium nitrite solution and the dyestuff developed in hot ammoniacal sodium acetate-oleylmethyltaurine solution. Lists of other suitable diazotizable amines and coupling components are given. Specifications 279,146, 319,247, 332,208 [all in Class 15(ii)], 392,011, 392,012 and 434,209 [all in Group IV] also are referred to.

Title: Improved vibration indicator
IPC: G01H13/00
Filed: 1959-05-26
Abstract: 855,759. Vibration indicators. GENERAL MOTORS CORPORATION. May 26, 1959 [June 9, 1958], No. 17898/59. Class 106 (4). A vibration indicator comprises a probe 76 axially movable into resilient engagement with a body 16 whose oscillations cause the probe to pivot about its end 84 and a pick-up 92 sensing these pivotal movements to give an indication of a characteristic of the oscillation. A vibration damper 12, comprising a hub 14 secured by a rubber annular mass 18 to an annular inertia weight 16, is secured by its hub 14 to a spindle 28. Air is then supplied to a motor 88, and its piston 90 moves a cylinder 44 towards the damper 12 until a detent 58 enters a groove 56 and the pointed end 80 of the probe strikes, and becomes embedded in the inertia weight 16. Air in the cylinder of motor 88 is released and the piston 90 withdraws, the resiliency of the weight 16 and probe shank 78 cause the probe 82 just to clear the end 71 of the cylinder 44. The probe shank 78 projects with radial clearance through a passage 70 in a spigot 52 of the cylinder 44 so that the rounded head 82 of the probe is free to pivot in a socket 86 formed in the end of a plunger 72 forced to the left by a spring 74. A motor 22 is started and, through a series of cams and gears, oscillates the spindle 28 and damper 12. The oscillation induced in the weight 16 causes pivotal movement of the probe 76 which is arranged to vary the reluctance of the pick-up 92 to produce a signal indicative of the oscillation of the weight 16. The speed of the motor 22 is increased until the resonanat frequency of the damper 12 is reached, determined by the amplitude of oscillation of the weight 16 or by a phase difference of 90 degrees between the vibrations of the hub 14 and weight 16. After the resonant frequency has been read on the meter 94, the motor 22 is stopped and air is supplied to a cylinder 62 to retract the detent 58. This permits a spring 54 to retract the cylinder 44 and extract the probe 76 from the weight 16. The spring 74 moves the plunger 72 to the left forcing the probe head 82 against the end 71 of the cylinder 44 thus holding probe 76 parallel to the axis of the cylinder 44.

Abstract: 653,577. Radio transmitting and receiving systems. WILLIAMS, R. STUART-, SHAND, G., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. July 8, 1948, No. 18412. [Class 40 (v)] In a pulse radar system having a common aerial for transmission and reception and a T.R. valve for isolating the receiver during transmission, means are provided for applying a priming voltage to a priming electrode of the valve after the end of each reception period and before the next transmitter pulse commences and also for holding off the priming voltage during the reception period. In the embodiment described, a 1,000-cycle A.C. supply, curve 1, Fig. 2, from transformer T, Fig. 1, is connected through a diode D to an artificial line L1, L2, C1, C2, C3. The line is charged through the diode during the first half of the negative half-cycle of the A.C., curve 2 ab and discharged at its output end by the modulator to form the modulating pulse, curve 3, for the transmitter. The line remains charged during the second half of the negative half-cycle, curve 2 bpc, the modulating pulse being arranged to commence at time p when the voltage at the output of the line rises to zero. This wave travels along the line to the input end which also rises to zero, curve cd. The wave after reflection at the input end travels back to the output to terminate the modulating pulse, curve 3. The T.R. valve TR, Fig. 1, has a priming electrode which is connected through resistance R3 to a potential divider R1, R2, connected across the input of the delay line. The electrode is an auxiliary cathode which is therefore supplied with a negative priming voltage, when the line is charged, this voltage being removed at time c in the middle of the modulating pulse, as shown in curve 4. In alternative arrangements, the modulator may be connected to the input end of the delay line and the potential divider R1, R2 to the output end, and the priming voltage may be positive and applied to an auxiliary anode.
