Title: Improvements in or relating to pulse delay circuits
IPC: G11C19/28
Filed: 1958-04-16
Abstract: 885,723. Transistor pulse delaying circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 16, 1958 [April 18, 1957], No. 12162/58. Class 40(6). In a pulse delay circuit comprising a transistor having a resistor arranged in series in its collector-emitter circuit, a short pulse which is to be delayed is applied to the emitter-base circuit of the transistor in such a sense as to render the emitter-base path conductive while a longer pulse having a width greater than the desired delay and whose leading edge coincides with that of the short pulse is applied through the resistor in a sense to reverse the bias to the collector-base diode of the transistor, whereby, owing to charge storage in the base zone of the transistor, the collector-emitter path of the transistor remains conductive for a predetermined time after the termination of the short pulse, the change in potential at one electrode of the transistor occurring at the end of this interval being used to generate (e.g. by differentiation) a delayed pulse. In a first embodiment, Fig. 1, a short pulse to be delayed is applied from a source 5 through a transformer 3 to the emitter-base path of the transistor 1 while a longer negative pulse derived from a source 7, which may for example, be a monostable trigger circuit, is applied through a resistor 6 to the collector electrode of the transistor. Owing to charge storage the transistor remains bottomed for a predetermined interval after the termination of the short pulse with the collector remaining substantially at earth potential. When, however, the charge carriers have been swept from the base of the transistor 1 by the long negative pulse, the collector potential rises negatively and a delayed pulse is supplied at the output terminals by means of a differentiating circuit 8, 9. In a further circuit, Fig. 3, the pulse to be delayed is derived by differentiation in the transformer 3<SP>1</SP> of the long pulse, the latter being applied to the collector-emitter circuit of the transistor 1 through a resistor 6 connected in this case to the emitter electrode of the transistor. The output of the circuit is applied to an integrating circuit 11, 12 which removes small pulses from the output signal and is then applied to a transistor amplifier 13 the output of which is differentiated to produce the delayed pulse by means of a circuit 14, 16. A small bias voltage source may be arranged in the emitter circuit of the collector 13 in order to improve the form of the pulse delivered at the output 10 and also to ensure that the transistor 13 'is rendered conductive only by positive pulses having an amplitude greater than the bias voltage. In a third embodiment, Fig. 4 (not shown), the pulse to be delayed is derived from the long pulse by means of a condenser resistor differentiating circuit. The resulting delayed pulse is then applied to an emitterfollower output stage. Specifications 827,666 and 835,907 are referred to.

Title: Improvements in machines for shaping and ironing collars
IPC: D06F71/22
Filed: 1923-05-10
Abstract: 212,162. Jackson, M. St. C. May 10, 1923. Ironing-machines specially constructed for treating collars.-In that class of ironing-machine in which a heated ironing-member presses upon the fold of a double collar suspended on the flange of a vertical cylindrical member with the faces of the collar on opposite sides of the flange, means are provided to lift the pressing-member out of contact with the collar at the time that the tab is passing so that the tab may retain its correct shape. In one form of apparatus the cylindrical member is stationary and the ironing-member is carried on an arm rotatably carried on the cylinder spindle. In another apparatus, the ironing-member 5, heated by a gas frame 16, is carried on a stationary arm 5<a> and coacts with the collar placed over the flange 2<b> of a cylindrical member 2 mounted on a shaft 2<a> rotated from the shaft 4<b>, Fig. 2. A bar 9, slidably mounted on the shaft 2<a>, and on a fixed standard 12, carries a guide member 9@ and a pin 10 slidable in a bracket secured to the standard 12. When, during rotation of the member 2 the tab of the collar strikes the guide 9<c>, the bar 9 is raised and the pin 10 frees a pin 14<c>, Figs. 2 and 6, to enable a spring, housed in a cam member 11, to push a second pin 14<d> into engagement with one of the teeth of a cog-wheel 13 secured to the shaft 2<a> The cam member 11. carried on a bar 14 loosely mounted on the shaft 2<a> is thus moved simultaneously with the cylindrical member and vertically under the tab.

Filed: 1966-03-23
Abstract: 1,128,402. Time switches. SMITHS INDUSTRIES Ltd. 21 March, 1967 [23 March, 1966], No. 12702/66. Heading H1N. A time switch wherein snap-action contacts 4 and 5 (Fig. 3) are alternately opened and closed by "OFF" tappets 22 and "ON" tappets 23 which engage respective sides of a wedge 8 on a member 13 pivoted at 10 (as disclosed in Specification 1,103,101) is provided with means to selectively permit radial sliding of at least one tappet arm such that engagement of its tappet with wedge 8 is ineffective in operating the latter. Tappet arms 12 and 21 have elongated central holes, which allow radial movement of their tappets 23 and 22 respectively inwardly and outwardly from their operative paths, and an adjustable control plate 25 of plastics material is pivoted concentrically with the tappet arms 11, 12, 20, 21. Wedge 8 extends through an aperture having upstanding lips 35 and 36 which respectively prevent radial movement of tappets 22 and 23 on arms 21 and 12 unless a respective recess 33 or 34 is aligned with the wedge 8. In the setting shown (diagrammatically) in Fig. 3, when tappet 22 on arm 21 engages the wedge 8 it is moved radially outwards into recess 33 and the contacts 4 and 5 are not opened. If plate 25 is rotated clockwise to bring recess 34 into alignment with wedge 8 the wall 35 prevents radial sliding of tappet arm 21 and its tappet 22 is effective to open contacts 4 and 5, but when tappet 23 on arm 12 engages the wedge 8 it is moved radially inwards into recess 34 and does not reclose contacts 4 and 5. In a mid-position of plate 25 both arms 12 and 21 are prevented from radial sliding movement and all four tappets are therefore effective. As shown in Fig. 6 a fixed centre post 37 carries a hollow shaft 28 integral with a gearwheel 38 through which it is driven at one revolution in 24 hours. A knob 45 is a friction fit on shaft 28 and has a flange 40 marked to indicate the hour of day and having dependent serrations 47 with which tappet arms 11, 12, 20, 21 are selectively engageable to be driven thereby. This arrangement thus allows arms 12 and 21 to slide radially without interference with their drive. The plate 25 has an arm (50, Figs. 5 and 8, not shown) accessible through a slot (59) in a cover-plate (58) whereby it is adjustable into its three positions which are located by a spring detent 55 engaging one of three slots (51, 52 or 53) moulded in the plate 25.

Title: Process for separating gases
Inventor: CRIBB GRAHAM THAME STANLEY
IPC: C10K1/10
Filed: 1959-04-15
Abstract: <PICT:0899611/III/1> Carbon dioxide is separated from gas mixtures by passing a stream of the gas through an absorbtion tower or column wherein the carbon dioxide is absorbed by a 2N to 8N ammoniacal solution lean in CO2, to produce a solution rich in CO2, passing the resulting solution through a heat exchanger under a pressure of at least 3, and preferably 5, atmospheres absolute, flashing the solution into a regenerator where the solution is heated indirectly to regenerate lean solution, passing this regenerated lean solution through the heat exchanger to heat the incoming rich solution, without coming into direct contact therewith, and thereafter returning the lean solution to the absorbtion column. Preferably the CO2: NH3 molar ratio in the liquor employed in the washing step is 0,6, and is regenerated when the ratio reaches 0,8.  The gas mixture may be one which has undergone a shift reaction to convert carbon monoxide to carbon dioxide.  Fig. 1 illustrates a suitable plant for carrying out the process of the invention, in which combustible gases which have undergone a shift reaction to convert carbon monoxide to carbon dioxide enter the plant at atmospheric pressure at point 10, and are forced by a booster 11 via a washer cooler 12 into the absorption column 13 and then via a washer 14, where ammonia is removed, to further stages in town gas manufacture.  Ammoniacal liquor is supplied from 15, and the effluent from 13 is stored in 17. This effluent is pumped by pump 18 and split into two streams, one of which is passed through heat exchanger 19 into preheater 20 from where it is flashed into flash chamber 22 via reducing valve 21. Some CO2 is released in 22, and more is expelled in reboiler 23.  The liquor from 23 is cooled in heat exchanger 19 and cooler 29, and returned to 15.  The second stream of effluent is cooled in cooler 24 and passed to the top of scrubber 25 to remove ammonia from the gases leaving the regenerator.  Final traces of ammonia are removed in acid scrubber 26.
