Title: Purification of 1,3-butylene glycol
IPC: C07C29/80
Filed: 1968-12-18
Abstract: 1,205,689. 1,3-Butylene glycol. CELANESE CORP. 18 Dec., 1968 [26 Dec., 1967], No. 60077/68. Heading C2C. 1,3-Butylene glycol is purified to reduce its content of odourous impurities by distilling the glycol by continuously feeding it to a point near the top of a distillation column, taking off overhead as vapour glycol having a high impurity content, continuously withdrawing liquid glycol from the column base, passing part of the withdrawn liquid glycol through a reboiler in which it is at least partly vaporized and then returning it to the column near but above the base and cooling and collecting as purified product the remainder of the withdrawn liquid glycol, the distillation being effected under reduced pressure while the hot glycol is in contact only with surfaces of stainless steel, or an equivalent material, e.g. glass, quartz, fused silica or ceramics.

Abstract: 1305050 Automatic control of extruder flow KABEL-UND METALLWERKE GUTEHOFFNUNGSHTTE AG 21 Dec 1970 [23 Dec 1969] 60447/70 Heading G3R In a method of maintaining constant wall thickness of a synthetic resin sheath which is extruded around an electric cable or a pipe 16 from resin granules, the granules are passed to the extruder 1 via a container 2 which is provided with a level sensor 3 having an output in the form of electrical pulses. The interval between the pulses is compared in a comparator 11 with a reference interval, and the resultant is used to control the extruder 1 or the draw-off system 15 of the cable or pipe. The reference interval is calculated by a computer 8 as a function of the draw-off speed, which is sensed by a tachogenerator 10, and the desired sheath weight per unit length, which is set on a potentiometer 9. The output from the comparator 11 passes to an evaluation stage 12 where it is modified in accordance with the speed of the extruder worm, as sensed by a tachogenerator 13. The diameter of the cable or pipe 16 may be measured by a device 17 at the entry to the extruder, and the result used to modify the setting of potentiometer 9. The level sensor 3 may be an ultrasonic or photo-electric sensor and its output pulses are used to tip the pan of a granule weighing machine 4 and to actuate a belt 6 to refill the pan from a hopper 5. In an alternative arrangement, the container 2 is refilled by a belt conveyer (7), Fig. 2, (not shown), which is provided with weighing means and the speed of which is controlled by the level sensor 3.

Patent GB-1375583-A (GB)
IPC: H04N1/403
Filed: 1971-12-30
Abstract: 1375583 Pulse shaping circuit; facsimile FUJITSU Ltd 30 Dec 1971 [30 Dec 1970] 60844/71 Headings H3T and H4F Shaping of binary signals, for example PCM signals or the full line signal of Fig. 6a obtained from a facsimile system, is effected by comparing the signals with delayed signals (shown dotted) and changing the relative level of one of the signals in a direction to increase the noise immunity, when it exceeds the given threshold. As shown, the delayed signal level is changed by limiting at a given threshold producing the crosshatched signal and the D.C. level is raised so that a comparator, which operates a switching circuit, produces the output train 6(b) with edges corresponding to the crossover points of the two signals. Alternatively the level changing may be effected by altering the D.C. level when the threshold value is reached so that the two signals are further separated. In Fig. 3 one end of a row of optical fibres is arranged across an advancing document and the other end is arranged in a circle which is scanned by a rotary system 29. The resulting signals are fed via an amplifier 311 to one input of a comparator 34 and via amplifying, delaying and limiting circuits 312, 32, 33 to the other input, to shape the output waveform as described above. In a detailed circuit (Fig. 4, not shown) the amplifiers (311, 312) have field effect transistor input stages and negative feedback. The delay is effected by a charge-storage diode 1S446, the clipping is effected by Zener diode (1S472) and the comparator output is passed to a square wave circuit (Tr5, Tr6).

IPC: H01J9/04
Filed: 1978-07-20
Abstract: Methods are disclosed wherein a porous tungsten body to be used in a dispenser cathode is formed and machined to substantially the desired size and shape. The surface of the body which is to serve as the cathode emissive surface is then conditioned by controlled electric discharge machining thereof with discharges between such surface and a nearby tool electrode, of copper and subsequently nickel, having an opposing surface shaped complementary to the desired shape of the cathode emissive surface.

Title: Propellant charges
Inventor: REDECKER KLAUS
IPC: C06B21/00
Filed: 1978-08-02
Abstract: Porous shaped propellent charge bodies particularly for caseless ammunition are produced by shaping a mixture of a high temperature resistant propellant, a filler and optionally a binder, the filler subsequently being removed to leave pores in the shaped composition. The filler is a thermally removable substance removed on heating the shaped composition to a suitable temperature, which temperature is below the decomposition temperature of the propellant. The preferred propellant is alpha-octogen, but reference is also made to RDX, PETN and many other materials. A preferred filler is ammonium hydrogen carbonate, but many other fillers are listed, such as organic compounds which are sublimed and polymers which are depolymerised.

Patent GB-2022365-A (GB)
Title: Communications network for data and voice
IPC: H04B7/185
Filed: 1979-05-30
Abstract: In a communications network including local and central nodes interconnected by terrestrial communications links, said central nodes being also interconnected via satellite links, originating nodes check and reserve a path across the network before transmitting data. Erroneous satellite data is repeated via terrestrial links. In a situation where connection is made to an X-25 computer and to a polled line, the network strips off the user protocol and only transmits that part of the information which represents usable data to the polled line. When the transmission is received back from the output port, appropriate protocol is reinserted, and it therefore appears to the external connections as if they are directly connected to each other.

Title: Joining fibre-reinforced tubular structures
IPC: E21B17/08
Filed: 1980-01-03
Abstract: This invention is concerned with fibre-reinforced resin pipes intended for applications in which the pipes will be subject to high-axial loadings, for example marine risers used in offshore oil or gas installations. Problems have hitherto been encountered in satisfactorily joining together such pipes, largely because of the often insufficient tensile strength of the jointing means. The present invention provides improved, screw-threaded jointing means and more particularly provides an open-ended tubular structure (3, 6) of fibre-reinforced resin material, at least an end portion thereof having integrally formed therewith an internal or external screw thread (4, 7), a substantial proportion of the fibres comprised in the screw thread extending substantially longitudinally of the structure. <IMAGE>

Filed: 1980-04-02
Abstract: A truck upright has a fixed upright section e.g. (20) one or more telescopic upright sections e.g. (26) and a load carrier e.g. (30) mounted on one of the telescopic sections.
