Abstract: 1,176,502. Steaming a web. VEPA A.G. 2 Oct, 1967 [12 Oct., 1966; 4 Nov., 1966], No. 44696/67. Heading D1L. [Also in Division F4] In a process and apparatus for steaming materials which can be stressed in a lengthwise direction, such as a length or web of material, the material is guided, in a contact-free manner, partly around at least one drum, such as a sieve-drum or slatted drum on a cushion of steam. Each sieve-drum may be provided with an axial fan 9, Fig. 2, whose direction of rotation can be reversed so that the drum can function as a blowing sieve-drum or a suction sieve drum. Heaters 10 may be provided. A suitable blowing sieve-drum shown in Fig. 4 has projecting slats 23 mounted on its peripheral, perforated wall. These slats are inclined, so as to direct steam issuing from the perforations in the direction of travel of the web of material 15. The apparatus shown in Figs. 1 and 2 comprises a heat-insulated housing 1, which is divided, by a partition 2, into a front chamber 3 accommodating two blowing sievedrums 4, and a rear chamber 5 accommodating two suction sieve drums 6. Perforated screens 11 are provided within the housing 1 above and beneath the drums 4 and 6. In each drum 4 is located a concentric, stationary drum 13, whose peripheral wall is perforated in that part adjacent to the peripheral part of the drum 4 covered externally by the material 15. In each drum 6 is mounted a stationary curved baffle 14, which covers the perforations in the peripheral wall of the drum not covered externally by the material 15. A travelling web of material 15 is, for example, impregnated with a solution of an artificial resin or dye in a padder 16, then squeezed between rollers 17 which remove some of the solution, and then passed, through an opening in the front end-wall of the housing and over a polished roller 18 then in a contact-free manner, under the first drum 4 and over the second drum 4, then through an opening in the partition 2, under the first drum 6 and over the second drum 6, and then out of the housing 1, e.g. between rollers in an opening in the rear end-wall of the housing. Means 20 and 21, Fig. 2, for rotatably driving, respectively, the fans 9 and the drums, are externally mounted on opposite side-walls of the housing. Saturated steam is generated in a sump at the base of the housing 1. An adjustable flap 19 may be provided, in the passageway between the top wall of the housing and the upper screen 11, to control the size of another opening in the partition 2 and consequentially the flow of steam between the chambers 3 and 5. In the embodiment shown in Fig. 3 the material passes in a contact-free manner round a blowing roller 22 and then around two blowing drums 4 arranged one above the other. Suction drums 6 and blowing drums 4 may be arranged alternately in one row Fig. 5 (not shown) or staggered in two rows Fig. 6 (not shown).

Title: Emission spectroscopy apparatus including an arc discharge supply
IPC: H02M7/523
Filed: 1973-09-26
Abstract: 1443198 Capacitor energising circuits for spectrometry PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 Sept 1973 [29 Sept 1972] 45079/73 Heading H2H An arc emission spectroscopy apparatus comprises a spark gap device in series with a triggered spark gap, the spark gap device being rendered conductive by the triggering of the triggered spark gap, the energy to maintain the spark gap device conductive being obtained from a circuit separate from that which supplies the trigger pulse to the triggered spark gap. A capacitor 5 is charged initially by a pulse # 1  to render thyristor 6 conductive whereupon the capacitor assumes a voltage of -2V AUX . This charging current is oscillatory and when this current reverses a pulse # 2  is applied to a thyristor 8 which then conducts and the capacitor 5 eventually assumes a voltage of 2V TRIG  + 2V AUX . The pulse # 2  is simultaneously applied to a thyristor 17 which becomes conductive so enabling a further capacitor 18 to become charged to a voltage of 2V BT  plus any residual voltage as the capacitor. A pulse # 3  applied to a thyristor 12 causes the capacitor 5 to discharge into a transformer 13 which triggers a triggered spark gap 15. This gap breaks down with the result that a high voltage wave having a steep wave front is applied to an analytical spark gap 16 which becomes conductive, the charged capacitor 18 then discharging across the ionised gap 16 by way of inductors 23, 21 and diode 24. If desired contacts 28 may be changed over so that the capacitor 18 charges to a voltage of 2V BT  + 2V BT <SP>1</SP> and the diode 24 short circuit so that the discharge of the capacitor 18 across the gap 16 is oscillatory. Elements 10, 25 are provided to control the charging of the capacitors 5, 18 respectively.

Title: Power supply systems
IPC: H04B5/00
Filed: 1971-08-24
Abstract: 1358687 Inductive signalling; transponders; time delay switching circuits PLESSEY CO Ltd 24 Aug 1971 [24 Sept 1970] 45470/70 Headings H4L, H4U and H3T In a power supply system of the type which receives, rectifies and stores radiated energy, e.g. to energize a transponder carried by a vehicle or person for identification purposes, the energy is released from the store for power supply purposes only in response to a reduction in the radiated energy received thus enabling a reasonable quantity of energy to be stored before it is utilized. In one arrangement, Fig. 1 (not shown) a transmitter is coupled to an aerial via a switch which is closed for short periods. The power supply system includes a receiving aerial coupled to a storage device via a rectifier, the output of the store being connected to a switch which is responsive to a reduction in output from the rectifier to apply power from the store to a device. In a further arrangement, Fig. 2, for providing power for a moving device 10 which carries a power supply of the type described, a stationary power source 11 feeds a loop 12 comprising a high output section A and a low output section B. When the device moves from A to B a reduction of input energy to the store of the power supply for the moving device will cause energy to be supplied via the switch to a transmitter (not shown) to cause it to transmit an identification signal. The weaker signal from section B provides a reference signal, for example. Details of power supply, Fig. 3.-Signals received by aerial 14 are rectified at 15 and supplied via integrator 16, 17 and diode 18 to a capacitor store 19. Diode 18 is shunted by a transistor 20 which feeds the base of a transistor 26, which with transistor 23 forms the switch controlling power supply from the store 19 to the device 27. Initially, capacitor 19 is discharged and transistor 20 is off. As capacitor 19 charges, the voltage V 2  follows the voltage V 1  across capacitor 16, differing by the voltage drop across diode 18. When V 1  drops, a point will be reached when the voltage V 2 -V 1 , is sufficient to make transistor 20 conductive, followed by transistors 23, 26, the switching-on time being largely determined by the time constant of circuit 16, 17. The circuit is arranged so that transistor 26 remains on when transistor 20 is turned off until the voltage across transistor 23 falls to a predetermined value. A Zener diode 28 prevents the voltage across device 27 from exceeding a predetermined value.

Title: Treatment of hydrocarbon mixtures
IPC: C07C5/02
Filed: 1961-12-21
Abstract: The selective hydrogenation of (a) unsaturated straight chain hydrocarbons mixed with branched chain or cyclic saturated or unsaturated hydrocarbons or (b) more highly unsaturated straight chain hydrocarbons mixed with less highly unsaturated straight chain hydrocarbons is effected by contacting the mixture with a molecular sieve which has a hydrogenating Group VIII metal catalyst incorporated therein by ion-exchange followed by reduction and simultaneously or subsequently contacting the sieve with hydrogen whereby the adsorbed unsaturated hydrocarbons are desorbed and, at least in part, hydrogenated.  The contacting of hydrocarbons with the molecular sieve, which may be 3-15 <\>rA, may be effected in liquid or vapour phase, e.g. at 0-500 DEG  C. and 0-1000 p.s.i.g. with a gaseous flow rate of 10-3000 gaseous volumes of feed per hour per volume of catalyst.  If hydrogenation is effected subsequently the sieve may be purged of unadsorbed hydrocarbons and if desired the adsorbed hydrocarbons may be partially desorbed without change and only the residue which cannot be desorbed without cracking or polymerization then hydrogenated and the hydrogenated product desorbed.  Examples describe (1) the adsorption of n-hexene from a feed containing mostly iso-hexenes on a 5<\>rA sieve containing nickel and subsequently hydrogenating the adsorbed n-hexene and recovering n-hexane; (2)-(4) contacting propylene containing propadiene and methylacetylene with hydrogen and 5<\>rA sieves containing nickel or cobalt to obtain propylene free from more unsaturated compounds.ALSO:In the separation of (a) unsaturated straight chain hydrocarbons from branched chain or cyclic saturated or unsaturated hydrocarbons or (b) more highly unsaturated straight chain hydrocarbons from less highly unsaturated straight chain hydrocarbons by adsorption on a molecular sieve, there is used a molecular sieve having incorporated therein by ion exchange followed by reduction a Group VIII metal hydrogenation catalyst and at least part of the adsorbed unsaturated material is desorbed and simultaneously hydrogenated by contact of the sieve with hydrogen. Part of the adsorbed material may be recovered first without change by mild desorption and more strongly adsorbed materials are removed by the hydrogen treatment thereby regenerating the sieve.  A 34-15 sieve may be used, adsorption and hydrogen treatment being effected at 0-500  DEG C. and 0-1000 p.s.i.g. with a GHSV of 10-3000 vol./vol./hr.

A program controlled computer operates with alternate " call " instructions and " arithmetic " instructions, a " call " instruction being effective during its cycle time to retrieve an " arithmetic " instruction from the memory, the " arithmetic " instruction being executed in the immediately subsequent cycle time, the computer having means, when a series of adjacent arithmetic instructions is to be repeatedly executed, for retrieving the next arithmetic instruction from the memory during the execution of the current arithmetic instruction cycle time. As shown in Fig. 1, a computer has a core store KS, arithmetic unit RW, and three registers for registering instructions; a " call " register c, an " instruction " register b serving mainly for serial-to-parallel conversion, and a " control " register r holding the instruction currently being executed. When the instruction sequencing is with alternate " call " and " arithmetic " instructions (called the " twostep " method), a " call " instruction is stored in the "instruction" register b and in the control register r and is effective in the register r during its cycle time T E , Fig. 2, to read out an " arithmetic " instruction from the memory serially to the " instruction " register b, the " call " instruction being, simultaneously transferred via an add one adder Ad1 to the register c. The arithmetic instruction is transferred in parallel to the register r where it is effective during the subsequent instruction execution period T A , Fig. 2, to read out the operand from the memory KS for processing in the arithmetic unit RW, the incremented call instruction being transferred via gate A2 during this period to the register b to be effective during the next instruction call period. The execution of a long series of adjacent instructions is expedited by the provision of the paths shown in thick lines in Fig. 1 and the gates A3-A5. As shown in Fig. 3, during an arithmetic instruction execution cycle time, in addition to the instruction execution, the address part of the call instruction in the register is transferred via the gate A4 to the register r where it is effective to read out in parallel via gate A5 the next arithmetic instruction to the register b the address part of the call instrument being transferred back after incrementation by unity at Ad2 to the call register c. Embodiments employing a drum memory as well as a core memory and having two-address instructions are described with reference to Figs. 5 and 6-8 (not shown).
