Title: Diene separation process
IPC: B01D71/44
Filed: 1973-11-28
Abstract: 1434639 Separating dienes from monoenes MONSANTO CO 28 Nov 1973 55077/73 Heading C5E [Also in Division B1] A diene is separated from an organic mixture comprising diene and monoene by contacting the mixture with one side of a polymeric permeation membrane comprising a halogenated ethylene polymer, a glycidyl methacrylate polymer, an aromatic imide polymer (which may be blended) or a homopolymeric N-vinylpyrrolidone (which may not be blended with acrylonitrile), and withdrawing at the second side a vaporous mixture having a higher concentration of diene than the feed mixture, the mixture at the second side being maintained at a lower chemical potential than the feed side. The feed mixture may be in the liquid or vapour phase. The pressure on the second side is less than that on the feed side and is preferably less than atmospheric. The polymeric permeation membrane may have a transition metal, in metallic or combined form, molecularly dispersed therein, in an oxidation state such as to permit chemical interaction with the diene. Examples of such metal compounds are Pd(benzonitrile) 2 Cl 2 , HgCl 2 , AgBF 4 , AgSbF 6 , AgPF 4 , Rh(C 2 H 4 ) 4 Cl 2  and Pt(PPh 3 ) 2 C 2 H 4 . Examples describe the separation of 1,3-butadiene from admixture with 2-butene, and of isoprene from admixture with hexene and pentane.

Title: Process for the manufacture of articles having a load bearing structure of thermosetting plastics material

Filed: 1971-11-29
Abstract: 1370438 Multilayer pipes GINSA GENERAL INVENTORS SA 29 Nov 1971 [5 Dec 1970 13 Sept 1971] 55369/71 Heading B5A [Also in Divisions B2 and F2] Tubular plastics structures comprising an intermediate plastics layer, e.g. expanded polyurethane, with plastics reinforcing layers on each surface are made by forming the intermediate layer with at least one helical groove extending through the thickness thereof, and placing in the groove(s) plastics material which is then hardened to form helical reinforcing elements connecting the surface layers and bonded to or unified with them. The reinforcing plastics may be thermosetting. The constituent layers may all be deposited on to a rotating mandrel by spraying. After the intermediate layer has been deposited, at least one helical groove is cut therein to constitute spaces for the connecting elements; resin is then applied to fill the grooves and form the outer reinforcing layers. The cutter may be shaped to provide a groove of bevelled cross-section. Glass filamentary reinforcement may be provided in the groove by feeding therein continuous filaments which have been individually impregnated by passage through a bath containing resin. The rotating mandrel may be replaced by a stationary detachable cylindrical shell around which the means for depositing the layers and cutting the groove(s) rotates; this is particularly useful for the manufacture on site of vertical reservoir and tower walls. The process may be modified by winding a preformed strip of plastics material around the mandrel or shell to constitute the intermediate layer, the connecting elements being formed in spaces between the windings and/or by the juxtaposition of coatings on the edges of the strip; the internal and external surfaces of the product are then coated with resin, e.g. by spraying.

Title: Improvements in or relating to fluid-operated percussive tools
IPC: B25D9/18
Filed: 1967-12-27
Abstract: 1,209,489. Percussive tools. FORGES ET ATELIERS DE MEUDON. 27 Dec., 1967 [24 Jan., 1967], No. 58643/67. Heading B4C. A percussion tool actuated by incompressible liquid comprises a piston 2, which with cylinder 1 defines an upper chamber 10 and a lower chamber 12, the upper chamber being in constant communication with a pressure fluid supply port 9, and the lower chamber being alternately in communication with an exhaust port 15 and the supply port. The chamber 12 is of a greater effective cross-sectional area than the chamber 10. The tool also includes a distributer valve 3 and a pilot slide valve 4. In operation, just as the piston has struck bit 8, pressure fluid in chamber 10 forces the slide valve 4 to its lowermost position (as shown) and fluid flows from the supply port to force the distributer valve 3 against its spring, thus causing the lower chamber to be in communication with the supply port (Fig. 2, not shown). Due to the greater force being exerted on the piston by fluid in the lower chamber than that in the upper chamber, the piston will be forced away from the bit. When the piston reaches its uppermost position (Fig. 3, not shown) pressure fluid in chamber 12 will force the slide valve 4 upwardly, thus enabling pressure fluid acting on distributer valve 3 to be exhausted. The valve 3, under action of its spring 14, moves upwardly and causes the lower chamber to communicate with the exhaust port. The piston then commences its downward stroke. Excess fluid output is absorbed by an accumulator 5-7. The tool may include a rotary tool bit-holder which is rotated through a predetermined angle, during upward movement of the piston, by an hydraulic motor (Figs. 5-7, not shown).

Abstract: 1385049 Motor vehicle fault indicators GENERAL MOTORS CORP 21 Dec 1972 [29 Dec 1971] 59037/72 Heading B7H [Also in Division G4] In a system for indicating the operating condition of each of a plurality of devices in a motor vehicle, to the driver, faulty operation of any one of the devices is detected, and indicated by moving an indicator scale (arranged at the periphery of a drum) and a warning lamp (which internally illuminates the drum) relative to each other so that the lamp illuminates a respective fault-indicating field of the scale. In one embodiment, a motor-driven drum bearing the scale is rotated continuously in synchronism with a wiper switch scanning leads from the fault detectors. When the switch reaches an energized lead the motor is stopped and the lamp energized, the motor being re-started after a delay. In a modification, the motor only runs when at least one of the fault leads is energized. In a further modification, a cylindrical coaxial inner extension of the drum carries holes through which respective photodetectors can be illuminated by the lamp, the photodetectors being connected to respective fault leads, this arrangement replacing the wiper switch. Each photodetector conducts except when illuminated. The motor and lamp are turned on when any fault lead is energized. When the hole corresponding to the lead energized is aligned with the photodetector in that lead, the signal is blocked, the motor is stopped, and after a delay the lamp is extinguished. The indicator scale may be moved to several positions in turn in response to a particular type of fault.

Abstract: 1315869 Travelling wave tubes SIEMENS AG 18 Dec 1970 [23 Dec 1969] 60350/70 Heading H1D In a travelling wave tube an electron beam is projected from a beam generating system 1 to a collector electrode 4 via a single continuous delay line system including a first section that has a given specific delay time, and a second resonant section 8 that is inserted adjacent the collector electrode end of said system and has a delay time that is constant throughout its length or varies along its length but is at all points greater than the said specific delay time, the resonant section being formed by reflection forming discontinuities and having a length equal to a whole number multiple of halfwavelengths of that wavelength on the line corresponding to the mean operating frequency. The resonant section may be constant or varied in step-wise or continuous fashion or may have alternate greater or smaller c/v values varying in step-wise or continuous manner. The c/v variations can be obtained by variation of coil diameter or pitch or by metallic or dielectric sheathing. The beam may be focused by a conventional magnetic field system using coils or permanent magnets to produce a constant or periodic field. Sections 6 and 7 are separated by a decoupling reflection free attenuator 5 and terminal section 9 connected to output line 3 and circulator 10. The reflection forming discontinuities may have reflection factors of different values but are preferably of equal magnitude, these values determining the Q value and effective bandwidth. Terminal section 9 has a length equal to one or more quarter wavelengths to act as a transformer and ensure there is no further interaction with the beam. Efficiency may be improved by an increase in the field strength within the section 8, and by the provision of "depressed collector" operation.
