Patent GB-829056-A (GB)
Abstract: 829,056. Recording-apparatus. REYNOLDS, V. T. Feb. 14, 1958 [Feb. 14, 1957], No. 4880/58. Drawings to Specification. Class 106 (4). [Also in Groups XXXV and XL (c)] In an apparatus for obtaining a visual recording to a depth scale from a magnetic recording to a time scale of a seismic test a flat stationary support-plate carries a magnetic strip or tape on which are recorded, on an arrival time basis, the signals received at a number of spaced geophones. A number of scanner heads scan the signals corresponding to each geophone and feed signals to an equal number of reflecting galvanometers which reflect beams of light through a slit on to a photographic film. Correction for differences in shotpoint arrival time at each geophone are corrected by adjusting the relative positions of the scanner heads. By means of cam and other mechanisms the scanner heads are individually moved relative to the magnetic tape, and the galvanometers and slit are moved relative to the photographic film at varying rates such that both static and dynamic errors are corrected, thus giving a record on the film to a depth scale.

Title: Continuous separation of reaction products
Inventor: MATTIASSON BO GUSTAV
IPC: C12M1/12
Filed: 1984-12-12
Abstract: A process and an apparatus for continuous separation and purification of reaction products produced in a multiphase liquid reaction mixture system in the presence of catalysts is described. The reaction products are partitioned between the phases in the multiphase system and one or more of the phases are removed continuously from the phase system and treated in an ultrafiltration unit where one or more products are separated. The apparatus include a reactor (1) for reaction in a liquid multiphase system and a connected ultrafiltration unit (11) containing a semipermeable membrane (12) for separation of produced low molecular weight reaction products. The reactor is divided into a mixing chamber (2) and a settling chamber (3) with a net (4). In operation, the stirred mixture flows continuously through the net (4) to chamber (3) where the phase separation takes place. Enzymatic conversion of starch to glucose is exemplified. <IMAGE>

Title: Improvements in extruder screws
Inventor: MARVEN ROBERT
IPC: B29C48/38
Filed: 1985-03-08
Abstract: An extruder has a barrel 1 with screw section 9 of larger diameter and coarser pitch and screw section 10 of smaller diameter and finer pitch both separately rotatable therein in the same sense, to move material from inlet 6c to melt outlet 8c. Section 10 is mounted on shaft 17 passing through section 9. Separate drives for screws 9, 10 are provided by motors 4, 5, separately controlled by gearboxes 20, 21 respectively, or separate gear control from a single motor. Thus feed section 6 of the barrel, fed through orifice 6c with non-uniform scrap polymer is controlled separately from metering section 8 feeding outlet 8c, whereby non-uniformity of feed does not overload the extruder. Separate control can be effected by feedback of electrical load signals to control the speed of the motors. Seal 19 prevents molten polymer getting inside screw portion 9. <IMAGE>

Title: Domestic iron
Inventor: KOMAR MICHAEL NICHOLAS
IPC: D06F79/02
Filed: 1985-04-16
Abstract: A domestic iron (Figs. 1 to 6) has a handgrip (6) which is inclined at a substantial angle to the plane of the sole plate (3) so that the user's hand adopts a more natural, and therefore less tiring, position than with a conventional iron. The handgrip (6) may, for example, be inclined at an angle within the range of from 25 DEG  to 55 DEG  to the plane of the sole plate, and is preferably inclined at an angle of 30 DEG . A stable rest position for the iron is provided by a stand (Figs. 8 to 12) on which the iron is placed, on its sole plate (3), when not in use. The stand provides an inclined rest position for the iron, typically at an angle of 20 DEG  to the horizontal, the inclination being sufficient to ensure the cessation of the supply of steam from a steam iron. The iron may be filled with water while standing in this inclined position. <IMAGE>

Filed: 1985-09-02
Abstract: A multi layer electrochromic device comprises a transparent electrically conductive layer 12 such as indium tin oxide, an electrochromic material 13 such as a transition metal oxide bronze, a solid electrolyte 14 which is a fast ion conductor of ions of the metal which dissolves in the electrochromic material, a guest metal sink layer 15 which may be of electrochromic material, and a second transparent electrically conductive layer 16. The device may be used in a variable transmission window. The electrochromic material may be MoO3 or WO3. The solid electrolyte 14 may be a Bordeaux glass of LiCl, Li2O or B2O3. A quantity of metal colouration atoms, for example lithium, may be transferred reversibly between the electrochromic and guest metal sink layers 13 and 15 by applying potentials to contacts. A given quantity of metal colouration atoms produces a colouration of greater density in one layer than in the other, for example by having one layer 15 thicker than the other layer 13.

Title: Optical phase control
Inventor: WRIGHT STEPHEN
IPC: H01Q3/26
Filed: 1985-10-18
Abstract: An intensity-modulated optical signal is input to a first fibre Mach-Zehnder interferometer (1) which is operated such as to control (2) the relative optical path lengths of its two arms whereby a predetermined power-split ratio is obtained between the optical signals coupled, by a 3 x 3 coupler (6), to a three-armed fibre Mach-Zehnder interferometer (7) whose arms provide 120 DEG differential delays at the modulation frequency. The signals output from the second interferometer (7) are summed incoherently, the summed optical signal having a modulation phase determined by the relative optical phases set by the first interferometer (1). 360 DEG control of the modulation phase is thus achieved and the magnitude of the resultant signal following demodulation of the resultant optical signal does not vary with the optical phase difference. Control (2) may be a piezo-electric fibre stretcher. The arrangement forms an optical vector modulator used in driving antenna elements of a phased-array radar system. <IMAGE>
