Title: Improvements in or relating to discharge tubes for projectiles
Inventor: RIEDEL WALTHER
IPC: F41F3/08
Filed: 1962-01-18
Abstract: 982,257. Torpedo launching tubes. PINTSCH BAMAG A.G. Jan. 18, 1962 [Jan. 18, 1961], No. 1955/62. Heading B7A.  A tube 1 for launching torpedoes, depth charges and mines has a rear closure 2 in which is a storage chamber for gas under pressure fed to the chamber through a movable pipe connected to a gas reservoir, the pipe connection being provided with shut-off means and means being provided to vent the chamber to the tube. In Fig. 1, the closure 2 comprises two bowl-shaped members connected by a sealing ring 5, the closure being pivotally mounted on hinge members 6, 7 and secured in the closing position by engagement of a rotatable ring 9 with projections on the ring 5. Compressed air is led into the closure through a pipe 11, which may pass through one or more of the hinge members 6, 7. In the supply pipe is a shut-off valve 12 and a pressure gauge 14 and a relief valve 13 may also be provided. An outlet nozzle 18 for the chamber 2 has a distributer 20 and is closed by a spring-supported member 21 of a piston-type valve 17 and the valve chamber is closed by a cover 19 from which a pipe 24 leads to a control valve 25. As air enters the chamber, it passes into the valve 17 through ports 23 and leaks through a port 26 to equalize pressure on both sides of the member 21. Pressure within the chamber 2 may be relieved by a pipe 15 furnished with a check-valve 16, the pipe 15 also being used to drain away moisture. When sufficient pressure has been built up in the chamber 2, and a torpedo is to be launched, the valve 25 is opened by pushing a control member 28 to vent the pipe 24 to a pipe 27. The sudden drop in pressure beneath the valve member 21 opens the valve 17 and allows air to flow through the nozzle 18 and so eject the torpedo. The valve 25 may be replaced by a valve which is opened by a pull. In a modification, Fig. 3, the outlet 18a is closed by a dished diaphragm 31a supported by a diaphragm 31b, the space between the diaphragms being in communication through ports 33 and an annular chamber 34 with a pipe 35 leading to a control valve 36. Valve 36 is connected by a pipe 24a to the cover 19a of the valve chamber 17a as in the first embodiment. With the members of the valve 36 in the positions shown, the pipe 35 communicates with the ambient air. To launch a torpedo, after the chamber 2a has been charged, during which charging air leaks into the valve chamber 17a through ports 23a, the valve stem 39 is pushed inwards so that the pipes 24a and 35 are in communication. Pressurized air then causes the diaphragm 31a to rupture, and the lower diaphragm 31b, then being initially loaded, ruptures also and allows air to escape into the discharge tube. To recharge the tube, the ring 31 carrying the diaphragms is changed after removal of an annular nut 32.

Abstract: 663,521. Current and voltage measuring. BAILEY METERS & CONTROLS, Ltd. Jan. 26, 1948 [Jan. 28, 1947], No. 2265/48. Class 37. A loop of four rectifiers, arranged to conduct in the same direction round the loop are energized with A.C. across one diagonal and D.C. across the other so that an A.C. potential which is a function of the D.C. appears between one of the points to which the D.C. is supplied and an intermediate point on an impedance across the A.C. source. A slowly varying D.C. potential applied to the rectifier bridge 10, fed with A.C. from transformer 30, causes an A.C. component to appear in the secondary of transformer 36. Assuming line 6 to become positive with respect to line 1, during succeeding half-cycles, rectifiers 20, 23 become more conducting than the rectifiers 21, 22 to cause an A.C. current to flow in the primary of transformer 36, Figs. 2 and 3 (not shown). The harmonics of the A.C. are removed by capacitor 39, the output signal being fed through amplifier 14 to valves 42, 43 energized from the same A.C. supply. One or other is caused to conduct to vary the saturation of the inductors 44, 45. A.C. fed to the motor M passes through the secondary of either inductor 44 or 45 to energize winding 50 or 51. The other winding, 51 or 50 is energized over capacitor 53 to cause the motor to rotate in one or other direction, moving the tapping 5 and thus balancing out the potential on lines 1, 6. The rectifiers may be arranged in a stack, Fig. 4 (not shown), and thermionic diodes may be used, Fig. 5 (not shown).

IPC: F26B21/00
Filed: 1969-01-17
Abstract: 1,242,316. Treating textiles. F. W. J. KARRER. 17 Jan., 1969 [18 Jan., 1968; 25 March, 1968], No. 2798/69. Heading D1L. [Also in Division F4] A method of treating (e.g. dyeing, bleaching and washing) and drying fibrous or filamentary material, e.g. spools 7 on perforated tubes 6, in a substantially closed container 1 in which two chambers 3 and 8 are formed and which communicate with each other through the material, comprises, as the drying procedure, the steps of establishing and maintaining a pressure difference between the chambers to cause a gaseous drying agent to pass through the material, e.g. by pump 4, simultaneously introducing in the initial stage of the drying procedure, air from conduit 9 and superheated steam from conduit 11 into the chamber 8 to partially dry the material by a mechanical action and to preheat the material to a temperature facilitating later drying by evaporation, and in the final drying stage introducing heated air with or without steam into the chamber 8 to further dry the material by evaporation of the moisture therein. In the initial drying stage substantially all of the superheated steam is condensed in the material. In the process described with reference to Fig. 2 the material is dyed, washed, bleached and dried. The container 21 (Fig. 2) is substantially the same as the container 1 (Fig. 1). In the process container 21 is initially evacuated by pump 52. Dye from container 22 is sucked into container 21 and this dye is then circulated through the material and heat exchanger 27 by pump 29. During the dyeing step alternate positive and negative pressures may be applied to container 21 by pump 52. When the material has been dyed the dye is forced through conduits 30, 43 and 44 to be discharged or through conduit 37 to container 22. The material is washed by sucking water from conduit 46 through the material and discharging it to water separator 54. The material is then bleached with agent (e.g. hypochlorite) from container 23, the bleaching being carried out in a manner similar to the dyeing step. The material is dried in two steps by firstly using cool air from conduit 50 and superheated steam from conduit 58 and then using hot air with or without steam. The material may be heated during the bleaching process by the introduction of steam and hot or cold air into the container 21. Air may also be introduced into the chamber 21 at the end of the dyeing process.

Title: Improvements in or relating to sewing machines
IPC: D05B73/12
Filed: 1941-03-04
Abstract: 547,678. Sewing-machines. JACKSON, L. MELLERSH-. (International Button Hole Sewing Machine Co.). March 4, 1941, No. 2941. [Class 112] A needle-bar 35 slides in a sleeve 34 mounted on cross pivots 36, 37 and is laterally vibrated in two directions at right-angles from cam-grooves 54, 55. For stitching a tacking group the groove 55 is a spiral joined up by a step portion and a spring 87 assists the bowl through the step portion. For attaching buttons, the groove is two semi-circular portions joined up by two step portions. The motion is communicated by means of a bar 63 sliding in a pivoted block 61. The groove 55 gives the bar a longitudinal motion by means of a lever 78 and a link 83. The groove 54 gives it an oscillatory motion through a lever 74, 71 and a link 68 and the amplitude may be varied by shifting the connection of the link 68 with the arm 71. For button-attaching, a slotted quadrant lever and adjustable radius rod may be inserted for varying the longitudinal movement. The shuttle and its shaft 110 are given an axial movement corresponding to the longitudinal movement of the bar 63 by means of a lever 115, fast on the shaft 77 carrying the lever 78, engaging between a pair of collars 112 on the shuttle shaft 110. The cyclical position of the shuttle beak is advanced and retarded to suit the transverse vibration of the needle by the relative displacement of helical toothed wheels 121, 122 by which the shuttle shaft is driven from a shaft 124. The wheel 121 is held from axial movement with the shuttle shaft 110 and the wheel 122 is carried by a sleeve 135 which is moved axially upon the shaft 124 by a third cam groove 56 acting through an arm 149, a quadrant lever 146, a link 143 and a lever 138. The shuttle is supported and driven by six levers 99 carried by the shaft and caused to move into and out of recesses in the shuttle body by a cam surface enclosing the levers and formed within a non-rotating block 96. The block 96 and a throat plate 195 attached to it move axially with the shuttle shaft 110. The bobbin case is held from rotation by the alternate engagement of arms 178 with a groove 177 in the bobbin-case front. These arms are carried on a shaft 170 which is oscillated by means of a lever 179 and a crankpin 191, which may be adjustable, on a disc 183 gear-driven from the shaft 124. The shuttle may be replaced by a rotary chain-stitch looper, Fig. 15, which is driven by the levers 99. In place of the bobbin-case retainer a needle-thread loop spreader is mounted on the shaft 170. The shuttle makes two revolutions for each stitch and the chain-stitch looper one revolution for each stitch. Accordingly, change wheels are provided for the shaft 124 and the large wheel connecting the wheels on the shafts 42, 124 is suitably mounte for the necessary adjustment.
