Title: Improvements in or relating to the permanent setting of woollen fabrics
Inventor: PERFECT JOHN RICHARD WADE
IPC: D06M11/54
Filed: 1960-03-10
Abstract: In a continuous process for treating a wool piece fabric to render it capable of receiving a permanent set or crease, the fabric having a moisture content of 25-100% based on the dry weight of the fabric is passed at a constant rate through a chamber into which a stream of sulphur dioxide is fed at a rate of 5-70 parts by weight of sulphur dioxide for every 100 parts dry weight of the fabric passing continuously through the chamber. After leaving the chamber the fabric may be exposed to air and/or <PICT:0933432/IV(a)/1> rinsed with water to remove any unabsorbed sulphur dioxide present, mangled to remove excess water and dried at a temperature below 80 DEG C.  In the drawing a wool piece fabric 1 is passed from a storage roll 2 through a carefully controlled water spray 3 and treatment chamber 4 fed with sulphur dioxide through pipe 5 and is then exposed to air at 6, rinsed in bath 7 and passed through the drier 9 to storage at 11. The fabric may subsequently be made up into garments and given a permanent set or crease by steaming with or without pressure. Specifications 480,448 and 775,486 are referred to.

Title: Improvements in and relating to tobacco rod forming methods and means
IPC: A24C5/18
Filed: 1936-08-28
Abstract: 486,419. Cigarette - making and like machines. DEARSLEY, G., SHACKLETON, J., and INDUSTRIAL MACHINERY CO., Ltd. Aug. 28, 1936, No. 8705/38. Divided out of 481,796. [Class 130] A continuous tobacco rod is formed by feeding tobacco into a passage or conduit and progressively reducing the speed of travel of the tobacco therein so that the rod is gradually built up by the contraction of the tobacco stream. The tobacco is showered on a horizontal feed band bv which it is delivered into a conduit 29 formed between curved elements 32, 33 arranged eccentrically to the axis of rotation of discs 30, 31, bv which the tobacco is fed through the conduit at a gradually decreasing speed, and delivered to a cigarette-paper web 35 on the garniture tape 34. The speed of the band feeding the tobacco between the elements 32, 33 is greater than that of the tape 34 and may be up to 50 per cent greater. In a modification, the discs 30, 31 are replaced by a hollow conical element having a helical or volute slot through which the tobacco is fed by inner and outer rotary members conforming to the surfaces of the conical element.

Title: Semiconductor signal generating circuit
IPC: H03K5/01
Filed: 1969-02-18
Abstract: 1,236,333. Transistor pulse circuits. HAZELTINE CORP. 18 Feb., 1968 [20 March, 1968], No. 8759/69. Heading H3T. A transistor 10 receives an input signal (A, Fig. 3, not shown) through a diode and stores it on its base-collector capacitance, the charge flowing away through the emitter junction and emitter resistor at the end of the input signal over a period of time (B2). The emitter output 17 may control a transistor switch 30 or a Schmitt trigger which responds at a particular level of the emitter output (B2) to turn on and off. The collector output of 30 may be fed back through a switch 28 to render the two transistors self-oscillating. An input pulse signal (c, Fig. 3, not shown) is applied through respective diodes 38, 39, Fig. 5, to transistors 34, 35 to charge the base-collector capacitance 20a, 20b thereof, the emitter of 34 being connected through a resistor 36 to the collector of 35 whose emitter is earthed, a point 37 on the resistor providing a substantially constant output proportional to the peak amplitude of the input pulses. The positive input pulse (C1) causes transistor 35 to saturate and to effectively earth one end of the resistor 36. The other transistor also conducts so that the voltage at the midpoint 37 of the resistor 36 is, for a pulse input amplitude of C1, equal to ¢C1. When the input pulse ends, the emitter of transistor 34 continues to conduct due to stored charge (on 20a), and its voltage decays from a value of V4-C1; meanwhile, transistor 35 being now non-conducting has its collector base capacitance 20b charged from 0 volts. The voltage towards which the transistor capacities respectively discharge and charge, provided the transistors are matched is then ¢Cl. The output at 37 is thus maintained at a D.C. level of one half the input amplitude

Abstract: 440,007. Track apparatus for train control AKT.-GES. METRUM, Wallisellen, Zurich, Switzerland. March 22, 1935, No. 9070. Convention date, Nov. 20, 1934. [Class 105] Train control apparatus of the type in which a direct-current magnet 1 on the locomotive energizes a winding 4 on the track which in turn feeds a track magnet to energize a locomotive winding is provided with two such track magnets 5, 6 and locomotive windings 2, 3 so that three controls can be effected according as one or other or both windings together are energized. The controls may be : at a caution signal, a braking which can be cancelled by an acknowledging key; at a stop signal, a braking which can only be cancelled after the train has come to rest ; at a " reduce speed " signal, a braking which is automatically cancelled or prevented as soon as or if the speed is below the prescribed limit. A relay a is included in the circuit of the magnet 1 so that any failure thereof will cause a contact a<1> to open in the circuit of the brake magnet g which normally is energized over front contacts c<2>, e<2> of stick relays c, e. The stick relays c, e are respectively dropped by the opening of back contacts b<1>, d<1> when relays b, d are briefly energized by the action of the track magnets 5, 6 on the windings 2, 3. At a caution signal the track magnet 5 and winding 2 are activated and so effect a braking by dropping the stick relay c. An acknowledging key WT allows the relay c to be picked up and so cancels the braking. At a danger signal the track magnet 6 and winding 3 are activated thereby dropping the relay e which can not be picked up till the train is stopped to permit access to a key NT. At a " reduce speed " signal, as for a branch line, the two track magnets 5, 6 and the two windings 2, 3 are activated thereby dropping both the stick relays c, e ; the two back contacts c<2>, e<3> thereupon continue the energization of the brake magnet g providing that the speed is low enough to close a speeddevice contact V. A relay f is also energized and contacts f<1>, f<2> thereof automatically pick up the relays c, e to restore the apparatus to the normal state. With the above arrangement the track winding 4 is short-circuited at a clear signal. However, the apparatus may instead be arranged so that at a clear signal it is automatically re-set by the relay f as described above ; any failure to re-set would then give a warning braking.
