Abstract: 963, 985. Fluid-pressure servomotor control systems. BAILEY METER CO. Aug. 16, 1960 [Sept. 15, 1959], No. 28424/60. Heading G3P. A device for converting electric to pneumatic signals comprises a beam 48 which is cored about a pivot 50 by electrical signals fed to coils 28a, 28b. Movement of the beam adjusts a baffle 56 controlling the leakage from a nozzle 58, this leakage acts on a fluid pressure device 62 to determine the fluid pressure output signal 64. The output signal is also fed through conduit 66 to a bellows 68 to act on a lever 72. The lever 72 is pivoted at 74 and its movement adjusts a spring loading 88 on the beam 48 to provide the feedback. The beam 48 is also loaded by a spring 100 and the lever 72 by a spring 98 connected to a lever 90 pivoted at 92. All the springs and the position of the nozzle 58 are adjustable initially to provide an output signal in the middle of the required range when the input signal is zero. In this position the lever 72 is parallel to the beam 48. The electrical circuit energizes coil 28a or 28b according to the input signal being negative or positive. The circuit includes thermistors 38, 44 so that the current fed to the coils 28a, 28b does not vary with ambient temperature.

Title: Improvements in or relating to Apparatus for the Continuous Manufacture of Artificial Sponges.
IPC: B29C44/00
Filed: 1967-06-21
Abstract: 1,185,488. Moulding sponge cloth. SPONCEL Ltd. 21 June, 1967 [22 June, 1966], No. 28658/67. Heading B5A. Artificial sponge is produced in a continuous length by an extrusion feed from an orifice 16 of viscose paste, containing reinforcing fibres and sodium sulphate crystals, into a rotated annular trough defined by an electrically insulating base on a horizontal rotary table 20, and vertical metal walls 2 and 3 comprising adjacent plates connected by fluid sealing and electrically insulated expansion joints 4, which plates are connected to a transformer 5 whereby the paste therebetween is subjected to a coagulating electric current. The sponge is then lifted from the trough up a fixed wedge shaped adjustable shoe 17, and through smooth freely rotatable horizontal rollers (21) (Fig. 5, not shown), by pairs (22) of variable speed driven fluted vertical rollers alternating with pairs (23) of vertical smooth freely rotatable rollers, and with the roller path having a slight curvature opposite to that of the mould. The coagulated paste passes to rinsing and finishing baths. Fixed pressure rollers 13 bear against the upper surface of the coagulating and shrinking paste around the mould, and liquid exuded therefrom is extracted by pumps 11 or scoop elevators and part thereof is recycled to coagulating parts of the paste by sprinklers 10. Gutters 7 and 8 along the mould walls 3, 2 protect the electrical contacts from liquid overflow. Stationary rubber scrapers 24 are arranged between the shoe 17 and the extrusion orifice 16 to define a fluid tight compartment within the mould into which rinsing liquid is sprayed from heads 25 and removed by suction pipes 26. The extrusion orifice 16 faces tangentially to the mould rotation direction and the feed pipe (15) thereto (Fig. 4, not shown) from the extrusion feed screw (14) is configured through a double change of direction whereby some disorientation of the reinforcing fibres is obtained. The mould may be of curved cross-section. The supply to the transformer 5 is from an asynchronous motor connected to a three phase source, an alternator and a rotary contact. The table 20 is rotated by a variable speed motor. The electrical supply can also be effected by converting three phase current to six phase which is converted to single phase by rectifiers and an alternator. The mould may be provided with a top gas exhausting cowl. The apparatus may also comprise three concentrically arranged or superimposed moulds.

Title: Process for the production of ú­-aminomethyl benzoic acid esters
Filed: 1954-10-05
Abstract: In a process for the production of p-aminomethyl benzoic acid esters an ester of a p-halogen methyl benzoic acid with an alcohol is reacted under pressure with ammonia, for example liquid ammonia, at a temperature of 0 DEG  to 30 DEG  C., preferably 10 DEG  to 15 DEG C., during a reaction period of up to two hours.  In a modification of the process a p-halogen methyl benzoic acid is first reacted with ammonia, for example liquid ammonia, under the conditions specified above and the acid formed is esterified with an alcohol.  Esters may be prepared from monovalent alcohols to give, e.g., the methyl, ethyl, butyl and amyl esters in diprimary alcohols, e.g. glycol may be employed for the esterification.  The free acid may be recovered from the ester by hydrolysis with cold hydrochloric acid.  In examples: commercial liquid ammonia is filtered through alkali-treated alumina to eliminate traces of iron and copper, is reacted under pressure with p-chloromethyl benzoic acid methyl ester to obtain p-aminomethyl benzoic methyl ester (1) and p-aminomethyl benzoic acid ethyl ester is similarly prepared from liquid ammonia and p-chloromethyl benzoic acid ethyl ester (4); p-aminomethyl benzoic acid methyl ester is obtained by reacting p-chloromethyl benzoic acid with liquid ammonia under pressure to obtain p-aminomethyl benzoic acid which is reacted with methanol (2); and the corresponding ethyl ester is similarly prepared (3). p-Chloromethyl benzoic acid methyl ester may be prepared by half oxydizing p-xylylene dichloride with, e.g. 50 per cent nitric acid at elevated temperature, separating the reaction product and esterifying the p-chloromethyl benzoic acid with methyl alcohol.

Title: Improvements in or relating to methods of preparation of thin layers of electroluminescent materials
IPC: H05B33/14
Filed: 1957-09-12
Abstract: A method of preparing thin layers of electroluminescent and photoluminescent materials comprising crystallized sulphides and/or oxides of metals and/or metalloids, comprises boiling the metal and/or metalloid components, such as cadmuim or zinc, of the materials in an appropriate gas atmosphere, such as hydrogen sulphide or oxygen, depositing the reaction products on a support as mono-crystals, removing the crystals from the gas atmosphere, evaporating under vacuum and condensing on to a heated base plate for re-crystallization.  The evaporation and re-crystallization is effected by evaporating the crystals within a vessel at a vacuum of 10-4 mm. beneath a heated base plate, the crystals being placed in heated crucibles arranged in an isotropic, e.g. rectangular, pattern beneath the base plate, which is maintained at a temperature higher than that of the crucibles.  The base plate can comprise a translucent plate of silica or Pyrex (Registered Trade Mark) on which is a thin translucent layer of a complex of metallic oxides.  The crucibles can be heated by high frequency induction, and the oxide layer of the base plate heated by an electrical current.  More than one complex of mono-crystals can be formed for preparing a complex sulphide and/or oxide layer. Specific temperatures and periods of heating are referred to.
