Abstract: 1,186,075. Granular electrical devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES'Ltd. 11 April, 1967 [14 April, 1966], No. 16563/67. Heading H1K. Grains 13, e.g. of chalcogerides of Cd, Zn or Pb, are applied to a support together with a liquid filler, and the filler is hardened and allowed or caused to retract between the grains so that parts 19 of the grains are free of the filler. Suitable filler materials include paraffin, polyurethane, fusible solid esters of saturated fatty acids, or thermoplastic materials, e.g. polyamides such as nylon. Hardening may be effected by application of heat or cold, by polymerization or polycondensation, under the action of gaseous reactants such as O 2 , or by evaporation of a solution. A photo-resistor such as that described in Specification 1,186,074 can be made according to the invention, indium electrodes 18, 21 being vapour deposited on opposite sides of the device. Alternatively, Cu electrodes may be applied to form a photo-voltaic cell. In one embodiment, grains having a core (43), Fig. 11 (not shown), and an outer coating (44) of different electrical properties are embedded in an insulating filler, and part of the coating (44) is removed by etching to reveal a section (46) of the core, thereby permitting an electrode to be applied to the bore. In this case a second layer (47) of insulating filler material may be applied to the surface after etching, so as to prevent the subsequently applied electrode from contacting the coating (44). The coating and core may be of the same or different semi-conductor material, different dopings being used in the former case, or alternatively one of them may comprise a metal. Other types of device to which the invention is applicable include photo-cells, temperature-sensitive or non-linear resistors bolometers, diodes, or xerographic plates.

Title: Improvements in or relating to apparatus for the direct analysis of spectral lines
IPC: G01J3/36
Filed: 1957-05-28
Abstract: 862,212. Photo-electric spectro-chemical analysis. REGIE NATIONALE DES USINES RENAULT. May 28, 1957 [June 8, 1956], No. 16923/57. Class 40(3) A spectro-chemical analysis system measures the light intensity in one line integrated over a period or alternatively the variation with time or evolution of the intensity of one line or a ratio of intensities. Figs. 1, 2 and 3 show a working unit, an integration unit and the control centre and Fig. 4 shows the connection of these units. A series of photo-cells is provided, each being connected to terminal 4 of an individual working unit. For integration, position 39 of switch 38, Fig. 3, is selected and switches 21 of the two integration units connected to the required working units (measurement and reference) are closed. The motor 20 starts at the initiation of sparking and closes the contact 24 when the spark has had time to stabilise. Relay 29 disconnects condensers 32, 33 from earth.. After a period of integration the contact 25 closes, switching the integrated outputs via terminals 18, 19 to the control centre terminals 58, 59. At the same time a steady voltage is switched to terminal 35 to energise relay 57 to switch the integrated output via terminals 60, 61 and amplifiers 72, 73 to a recorder 74. A contact in the sparking circuit is opened at the end of the measuring period by the motor 20, which opens contact 26 to de-energise relay 51. Several integrations can be programmed concurrently provided their measurement periods do not overlap. To record the evolution of the intensity ratio of two lines, position 40 of switch 38 is selected together with position 9 of switch 7 of a reference working unit and position 10 for a measurement working unit. The signals from the working units pass via terminals 63, 60 and 64, 61, to the amplifiers 72, 73 and the recorder 74. If the evolution of intensity of a single line is required a constant source connected to terminal 47 is programmed as reference. With this arrangement it is possible to correct the slit position. By selecting positions 41, 42 of switch 38 output from the photo-electric cells under constant and zero illumination respectively is recorded to check cell performance. An integration can be programmed while an evolution measurement proceeds and vice versa.

Abstract: 307,895. Dahl, O., and Kj÷rstad, E. A. H. March 17, 1928, [Convention date]. Cooling fish; cooling liquids by direct contact with cooling media; brine, circulating, through chambers.- A freezing plant, particularly adapted for fishing vessels, comprises several freezing chambers 8, 9, 10, through which cold brine is circulated and an ice-fed brine-cooling chamber or chambers 1, 2, all these chambers being connected between a cold brine collector 27 and a collector for the brine to be cooled and arranged so that one or more brine coolers or freezing chambers may be cut off from the circuit without interrupting the operation of the remainder. A compensating tank 14 is preferably associated with one of the collectors or with a brine cooler and a salt receptacle 5 may be included in the fluid circuit. The chambers are kept constantly filled with brine, in normal operation, by a pump 15, the pressure being sufficient to raise the liquid to the level A in vent pipes 47 from each chamber to the atmosphere. To permit a chamber to empty itself through a pipe 40 while a cock 31 is closed, a vertical bent pipe 37 communicating with the atmosphere connects each freezing chamber and optionally each brine cooling chamber to the following apparatus so that on cutting off a chamber the liquid will fall to level B and its return to that chamber will be prevented. To empty a chamber into the storage tank 14 a cock 43 is opened. To effect automatic emptying the cock 43 may be constantly open slightly or the pipe 40 may have a small cross section to permit a constant discharge through the pipe. When cocks 43 are fitted the excess pressure in the chambers may be adjusted by varying the rate of this byepass discharge. In a modification, Fig. 2, the brine cooler 52 also constitutes a storage tank and the bye-pass pipes 57 58 discharge direct into the main conduit 56. A level indicating device may be associated with the tank 14. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the substitution of clack valves for the bent pipes 37. Further, the fish boxes 11, 12, 13, Fig. 2 (Cancelled), may vary in size so that they may be nested when empty, the freezing chambers being similarly of various sizes to suit the boxes and adapted to receive a class of fish suited to the box and to a particular rate of freezing.
