Abstract: 925,982. Fluid-pressure servomotor control systems; valves. UNION CARBIDE CORPORATION. March 13, 1961 [March 15, 1960], No. 9007/61. Class 135. A method of controlling the pressure of oxygen in a manifold 9 for scarfing heads 8 of a thermochemical metal remove apparatus comprises feeding oxygen through a line 22 to a two-stage pressure regulator 1 and then through a line 20 to the manifold, the output from the second stage of the regulator being controlled in accordance with the pressure adjacent the manifold. This latter pressure is fed through lines 28, 30 and 32 to a compensator regulator 2 and controls the flow of oxygen from a line 38 to a line 40 such that the outlet pressure in the line 40 varies inversely as the variations of pressure in line 28. The line 40 leads to a solenoid-operated valve which, when open allows flow through a line 42 to the second stage of the main regulator 1 to control the second stage output. The regulator 2 is also supplied with a constant fluid pressure loading through line 36, pilot regulator 5, and lines 34, 32. Regulators 11, 13 having associated solenoidoperated valves similar to 3 are also provided to control flow of preheat and purging fluid pressure, the outlet of each leads to the line 42. The first stage of the pressure regulator 1 is formed by a diaphragm loaded on one side by fluid pressure fed through a pilot regulator 4 and on the other side by the first stage outlet pressure.

Title: Improvements in or relating to electric circuit arrangements
IPC: H04J3/20
Filed: 1965-03-04
Abstract: 1,038,745. Charge transfer switching circuit SIEMENS & HALSKE A.G. March 4, 1965 [March 5, 1964], No. 9212/65. Headings H4K, H4L and H4R. A switching circuit for controlling the transfer of energy from a first store to a second store in, for example, a time division multiplex communication, or telephone exchange, system uses an impedance converter comprising an amplifier of unity gain having a low impedance input connected in series with the first store and a high impedance output connected in parallel with the second store. Fig. 2 shows a system in which closure of the switch S0, which may be of the same type as that shown in detail at S1, stores a sample of the input signal Si on a first storage capacitor Cl. After switch SO has opened again a pulse TK1 applied to switch S1 causes S1 to close to connect a reference potential -U s 0 to the point al of capacitor C1. Capacitor C1 therefore discharges through transistor Tr1<SP>1</SP> and the resulting potential at the base of transistor Tr in the amplifier V causes this transistor to conduct. During this discharge diode D1 is reverse biased. If the resistors R1<SP>1</SP> and R1 in the amplifier V have been chosen correctly to give a gain of unity the current flowing in the collector circuit to charge the second storage capacitor C2 corresponds exactly to the discharge current from capacitor C1 and therefore, after the end of the TK1 pulse, the charge stored in capacitor C2 corresponds to that originally stored in capacitor C1. The charge stored in the capacitor may then be discharged through switch S2, which may be identical to switch S1, to a utilization device. To provide a delay circuit a number of stages similar to that described above may be arranged in cascade, Fig. 4 (not shown), each succeeding stage being fed with pulses which immediately precede the pulses fed to the preceding stage. Also described, Fig. 6 (not shown), is a circuit for generating a train of sequential pulses for operating the switching transistors in a delay circuit in which each pulse is produced via a differentiating transformer from the emitter current pulse of the succeeding stages switch, the pulse produced by the negative-going edge at the end of a pulse being used as the pulse for the preceding stage.

Title: Machine for making decorative bows
IPC: D04D11/00
Filed: 1964-03-06
Abstract: 996,548. Making bows or rosettes; feeding webs. G. N. CARMICHAEL. March 6, 1964 [April 19, 1963], No. 9489/64. Headings B6B and B6G. A machine for making a decorative bow comprises a reel 20, Fig. 1, from which a ribbon 16 is drawn until the end is held on an anvil 40, Figs. 1 and 3, by a spring guide 130. An arm 44 pivoted at 46 supports a rotatable spindle 52, Fig. 3, 11 and 12, itself supporting a holder 54 urged downwardly by a spring 60. With the holder held in an upper retracted position, Fig. 11, by a cam 68, a fastener 56 is inserted in a recess in the spindle 52 and the cam is then released so that the head 80 of the fastener is brought against the bottom of the holder 54. In operation, the arm 44 is moved downwards so that the fastener penetrates the ribbon and moves into a hole 132 in the anvil, the holder 54 being forced up into the position of Fig. 11. On raising the arm 44, the ribbon is gripped between the holder and the head 80 and a length of ribbon drawn off the reel. On the next downstroke of the arm 44, the spindle 52 is rotated by a rack 82 and pinion 86, the rack being connected to a link 114 pivoted to an element 100 so as to move relative to the arm. A one-way clutch and detent results in rotation of the spindle only on the downstroke. The amount of movement upwards of the arm 44 and therefore of rotation of the spindle is determined by a member 110 on the arm engaging an adjustable screw 112 on the member 100, which is also adjustable by means of a detent 104. The stroke is also adjusted by moving a spacer 126 along the member 110 so as to engage or not engage the screw. When the rotation of the spindle is less than 180 degrees, a pom-pom type bow 128, Fig. 13, is formed, and when it is more than 180 degrees, a star-type bow 118, Fig. 14, or, by using two ribbons 16, 36, a star-type bow 120, Fig. 15, is formed. The ribbons may be of different colours. The length of the loops is variable by means of the detent 104. Feeding webs.-The web 16 is drawn off the reel 20 by upward movement of the arm 44 in co-operation with a spring guide 130, being gripped between a holder 58 and the head 80 of the member 56. The reel is supported on an inclined plate having a non-slip facing 32 to act as a brake. The spindle 30 of the reel is also inclined to the normal to the plate so that the reel 20 will always engage the facing 28 below the spindle 30.

Title: Apparatus for wet treatment of fibrous or granular materials
IPC: D06B5/04
Filed: 1959-03-20
Abstract: <PICT:0885456/IV (c)/1> Apparatus for the wet treatment of fibrous or granular materials, e.g. textile fibres, wood shavings and paper particles, comprises a sieve drum within which a suction effect is produced by pressure-reducing means communicating with the interior of the drum, a sieve belt, a liquid bath, a pressing mechanism including two rollers of which one is partly within the bath and adjacent to the drum, whereas the other is wholly outside the bath, and an arcnate cover plate in the highest region inside the drum.  As shown, loose fibrous material is supplied to sieve drum 12 by way of a conveyer belt 1.  The suction effect within drum 12 is produced by a pump which at the same time ensures circulation of the liquid bath, and causes the material to cling to the periphery of the drum.  The sieve drum rotates in the direction indicated by the arrow, so that the material is delivered to lower roller 4, preferably arranged in the region of arcnate cover plate 6, at such a distance from the drum that the material is in contact both with the peripheral surface of the drum and also with roller 4. Sieve belt 5 assists in transference of material from drum 12 to rollers 4, 7 by urging the material away from the drum near the end of arcnate cover plate 6, e.g. by means of resiliently mounted roller 8.  Alternatively a spray pipe 9 washes material off sieve belt 5 and directs it between rollers 4, 7.  A conveyer 10 carries away material issuing from the delivery side of rolls 4, 7.
