Title: Doppler speed log for marine navigation systems
IPC: G01S15/60
Filed: 1972-06-28
Abstract: 1392005 Doppler speed log SPERRY RAND CORP 28 June 1972 [6 July 1971] 30238/72 Heading H4D  A marine pulsed Doppler speed log includes fore and aft sonic transducers, means for initiating a time gate in separate channels for processing fore and aft signals, means for terminating the gates after a specified number of sonic carrier cycles and means for indicating speed corresponding to any difference in the duration of the time gates of each channel. The described embodiment operates in two modes. In shallow water the amplitude of bottom echoes is detected as exceeding a predetermined threshold and is used to determine the vessel's speed. In deeper water a timing pulse is used to initiate a range gating of received echoes. In the receiver a counter 77 is set to zero by each transmitter pulse, this causes inverter 79 to enable AND gates 81, 83. At the occurrence of a bottom echo or a timing pulse the J input of bi-stable 87 is set to "1" and at the next cycle of echo signal AND gate 76 becomes enabled. Echo pulses now pass through into counter 77. After a count of 2048 the counter output goes high, thus disabling gates 81, 83 and switching the bi-stable 87, Q output to zero. Bi-stable 87 thus produces a pulse of length equal to exactly 2048 cycles of echo signal from a forward direction. A similar bi-stable in the aft channel produces a pulse for the rearward direction. AND gates 89, 91 receive the Q output of one channel and the Q output from the other and are thus disabled unless one pulse is longer than the other. One of these gates is thus opened to clock pulses from generator 101 (whose frequency is dependent on the sea-water temperature), for the time difference. Counter 111 accumulates the pulses which are proportional to the vessel's speed. The counter 111 content is sealed down by divider 121 and integrated to provide a distance indication in digital display 125. The counter output is also passed to a register 119 through electronic switch 113 directly and via decimal divider 115. If the measured speed falls below 1 knot register output 201 switches in the direct path to provide a more accurate indication. The register content is averaged over 384 measuring cycles and is read out into a further register 129 by a pulse from divider 127.

Abstract: 368,727. Electrodeposition of metals. CELLULOID CORPORATION, 290, Ferry Street, Newark, New Jersey, U.S.A. Oct. 9, 1930, No. 30314. Convention date, Oct 9, 1929. [Class 41.] In the electrodeposition of metals on articles by successive passages through or immersions in a plating bath, electrolyte is applied to the articles while out of the bath to prevent stratification of the deposits. The invention is particularly applicable to the plating of large drums and endless belts used in casting films of cellulose derivatives. In the apparatus shown in the Figure, the belt 13 to be plated passes over pulleys 2, 3 and a centrally-disposed upper pulley, not shown, above which is situated a sprinkler to which electrolyte is pumped from the vat. The upper pulley is adjustable. The belt 13 is guided within the bath by side members depending from a sheet 15 above the belt. The lower surface of the belt is polished by reciprocating brushes 21. Electric contact to the belt is made by brushes 45. Anode rods of 49 are mounted in notched supports 47 and are connected to a bus-bar 50. The belt is further polished by a rotary brush 38, the bristles of which are arranged in spiral form, so as to prevent formation of scratch lines. The brushes 21 may also be provided with staggered bristles for this purpose. The electrolyte is circulated to and from the vat past baffles 70, 74. Scum is removed by a pipe 53. The speed of the belt should be such that the interval between successive immersions is not more than one minute. The pulleys are flanged and may be provided with circumferential flutings ; they may be covered with hard rubber, cellulosic material or a phenol-aldehyde resin. In a modification, the vat slopes upwardly on each side from the centre where a third pulley is provided. In another modification the belt passes at the bottom round a single large pulley mounted in a vat of semicircular section. The pulley may be provided with blocks, shims, or an adjustable rim. The plating metal may be nickel or copper or both metals in succession. A belt may be made wholly by electrodeposition the cathode being prepared to facilitate removal of the deposit.

Abstract: 1,174,912. Programme control. BRITISH AIRCRAFT CORP. Ltd. Aug.2, 1967 [July 6, 1966], No.30378/66. Heading G3N. A circuit diagram is produced under control of a record strip carrying representations of discrete items of data relating to successive elemental areas of the circuit diagram by moving datacontrolled exposing devices relative to a lightsensitive sheet in synchronism with the reading of the data. As shown, a beam 1, carrying a plurality of lamps, is traversed by a lead-screw 2 and a punched tape 5 is moved in steps by a sprocket 12 driven through a Geneva mechanism 11 by a motor 10. The tape perforations are read by a sensing head 4 and the signals are applied to a distributer 13, synchronized through a pulse generator 14 with the tape, which energizes selected lamps of a group of lamps for a sufficient time to ensure an adequate exposure. When after a number of tape steps the total number of groups of lamps on the beam have been selectively energized, the next tape step causes the beam 1 to be advanced by the lead-screw 2 by the area on the light-sensitive sheet illuminated by the lamps. The developed sheet 3 forms a master negative for a printed circuit producing apparatus, the areas illuminated by the lamp forming lines corresponding to circuit paths. It is stated that square-ended bundles of fibre optics can replace the lamps on the beam.

Title: Improvements in or relating to the manufacture of synthetic resins, and products containing the same
IPC: C08G8/02
Filed: 1928-10-20
Abstract: 299,066. British Celanese, Ltd., (Assignees of Moss, W. H.). Oct. 21, 1927, [Convention date]. Phenol-ketone resins are produced by condensing a ketone with a pheno]-ketone such as diphenylol-propane which is made by condensing excess of a monohydric phenol with acetone in presence of a strong acid catalyst. The diphenyl propane may be condensed with acetone, or the resin may be formed direct by condensing phenol with an equimolecular proportion of acetone in presence of a strong acid. The resin is washed. and dried by distillation at ordinary or reduced pressure. Examples describe the production of the resin in each of the ways mentioned above, using hydrochloric acid as catalyst; the acetone may be replaced by other ketones such as methyl ethyl and diethyl ketones and the phenol by other monohydric phenols such as cresol. The resin is fusible and non-reactive and soluble in benzene. alcohol, and acetone and in the usual solvents for cellulose-ester lacquers. Lacquers may be made containing the synthetic resin and cellulose formate, acetate, propionate, butyrate, and nitrate, and cellulose ethers such as methyl, ethyl, and benzyl cellulose. An example of a lacquer is cellulose acetate, synthetic resin, triacetin, acetone, benzene, alcohol, and ethyl lactate. The synthetic resin may also be used in making plastic compositions. The Specification as open to inspection under Sect. 91. (3) (a) includes the use of other than monohydric phenols. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to dispersing insecticides or other pesticidal compoundsas vapours
Inventor: DINSDALE JOHN MERRITT
IPC: A01N25/20
Filed: 1948-11-23
Abstract: A composition for use in the generation of pesticidal smokes comprises a mixture of a thermally vaporizable pesticide which does not burn readily such as D.D.T. or benzene hexachloride, hexamine and an oxygen producing inorganic compound such as potassium chlorate. The ratio of pesticide to hexamine plus said inorganic material is between 1 : 1 and 3.5 : 1, whereas that of the said inorganic compound to the hexamine is between 0.75 : 1 and 5.0 : 1, preferably 2.4 : 1.  The composition is rendered non-explosive by the presence of 5 to 30 per cent of a finely divided inert material such as kaolin, diatomaceous silica or native magnesium silicate such as talc.  The composition may be placed in a suitable open ended container e.g. aluminium tube having an aperture at one end and then dusted with an igniter composition comprising e.g. the pesticide and potassium chlorate together with thiourea and urea or lead thiocyanate and kaolin. Alternatively, the composition may be used in the form of pellets produced by moistening the composition with a 1 per cent aqueous solution of gum arabic to form a crumbly mass, moulding into pellets and drying at 30-40 DEG C.  Pellets produced by moulding with alcohol may be dried at 50-60 DEG C.
