Title: Improvements relating to the manufacture of absorbent tampons
IPC: A61F13/20
Filed: 1945-04-28
Abstract: 591,165. Absorbent tampons. EDWARDS, L. W. C. April 28, 1945, No. 10743. [Class 81 (ii)] Absorbent tampons are made by folding a strip of fibrous material 1 into an S-shape (Fig. 3) partially compacting it by introducing it with one S-shaped end leading into a tubular die and subsequently compressing it by endwise pressure to the required shape (Fig. 6), which may be circular or nonagonal in cross-section. A withdrawal cord 2 may be previously attached to the middle of the strip, and the strip may be partially compressed into a split die before introduction into the tubular die. As shown in Fig. 7, a holder 7 supports a rotatable table 6, containing four similar tubular dies 11. Holes 12 in the holder correspond to the dies 11, three of the holes containing pressure plates 13. An S- shaped wad is introduced into the bell-mouth of an open die and the table given a quarter-turn. Operation of lever 9 actuates a hydraulic or other ram 8, which raises the unit, loosely-fitting plunger 17 thrusting the wad down into the die. After another quarter-turn, the wad is compressed by closely-fitting plunger 18. The last plunger 19 ejects the finished tampon through the open hole 12. Lever 9 also engages bar 14 which causes the quarter-turns of the table by a ratchet and freewheel attachment 15.

Title: Improvements in or relating to protective devices for alternators or synchronous alternating current motors
IPC: H02H7/08
Filed: 1951-05-09
Abstract: 706,992. Automatic control systems for synchronous machines. GENERAL ELECTRIC CO., Ltd., FRIEDLANDER, E. S., and MILNER, M. May 9, 1952 [May 9, 1951], No. 10940/51. Class 38 (4) In an automatic control system for a synchronous alternator (or motor) in which the reduction of field excitation on leading (or lagging) power factor loads is limited to maintain stability, the load current power factor is measured by a synchronous switch which energizes a polarized relay which controls a variable resistance in series with the operating coil of the automatic field regulator. An alternator 10, Fig. 1, is excited by a generator 13 controlled by a vibrating contact regulator 15, the coil of which is in series with a resistance 45 variable by a stepping relay 46 and resetting device 49. The synchronous switch 16 has a pair of contacts bridged by a commutator (or closed by a cam) for 180 electrical degrees during each rotation of the alternator. A four pole machine is illustrated. The stator of the switch is initially adjusted for zero output at some desired power factor. The ouptut of the switch controls the polarized relay 20 so that when the angle between the magnetic axis of the field system of the generator and the voltage vector of the alternating current supply fed to the circuit including the switch becomes excessive, the output to the relay exceeds a predetermined value, the relay closes contacts 27 to energize a relay 30 which applies a shunt 33 to the operating winding of the voltage regulator and, simultaneously, energizes the winding of the stepping switch 46 to introduce one additional step of resistance 45 into the regulator circuit. This operation will be repeated until the excitation of the alternator has been sufficiently boosted. When the angular displacement decreases below a certain value, the relay 20 closes contacts 28 to operate the resetting device 49. In an alternative. arrangement, Fig. 2, the rotary switch 17 is carried by the shaft of the alternator, and an adjustable pair of brushes 18, 19 energize the polarized relay 62 controlling a reversible motor 69 to adjust a resistor 67 connected in series with the voltage regulator 66. The motor armature is connected to a tapped resistor 74, 76 so that it will run faster in the direction to boost the alternator excitation than in the other. Alternatively the armature may be supplied from independent sources. It is stated that similar arrangements may be applied to the control of synchronous motors. Specification 662,761 is referred to.

Abstract: 496,044. Washing air. DE VILBISS CO. April 21, 1937, No. 11424. Convention date, April 21, 1936. [Class 55 (ii)] Air is cleaned, e.g. from paint particles, by treating it in a narrow circuitous passage 6, with a liquid spray projected through a slot 18 therein, forcing additional air into the passage through a slot 17, and then passing the air into an expansion chamber 7 with baffles 10 to remove excess liquid. The passage 6 into which the air is drawn by a fan 12 has a slot 18 dipping into water in a reservoir 3, and air under greater pressure forced by the fan 12 through a duct 16 or by a separate fan 40 into the reservoir 3 passes through slots 17, 18 into the air to be treated, water being entrained at 18. The direction of air flow is reversed in the passage 6. Water removed by the zigzag baffles 10 above the expansion chamber 7 collects in a trough 8 and is led by a pipe 9 into a compartment 21 of a tank 20, whence it passes in turn through submerged openings 26-28 in partition walls 25 to compartments 22-24 respectively, where solid impurities float or form sediment. Fresh water is supplied by a pipe 30, and the level in the tank 20 is the same as that of the reservoir 3, to which water is returned through an opening 5. A water wheel 42 in the slot 18 rotated by a motor 44 may add to the mixing effect of air and water in the shallow passage 6. The treated air passes from the fan 12 to exhaust, preferably about 20 per cent being returned through the duct 16 to the reservoir. A softening agent may be added to the water.
