Title: Contact copying apparatus
IPC: G03B27/12
Filed: 1971-04-19
Abstract: 1347117 Contact copying apparatus KALLE AG 19 April 1971 [16 April 1970] 26915/71 Heading G2A A contact copying apparatus comprises means e.g. belt 13, for feeding an original and copying material through the exposure zone of a transparent copying cylinder 16 characterised in that the feed direction is reversible so that the original and copying material may be conveyed to the  exposure zone from either of two sides of the zone. In the embodiment shown an original is fed into the apparatus from a desk 41. As the original travels over a belt 14 a length of copying material is fed and cut automatically from a roll 45, the original and copy material are then fed to the exposure zone via a nip 32 on the side of the apparatus remote from the intake for the original. Alternatively the direction of the belts is reversed and an original 12 and a sheet of copying material 11, which sheet is cut manually from a roll 42 or selected automatically from stacks 43 of sheets of different sizes, are fed from a desk 10 by belts 13, 14, through the exposure zone. After exposure the original adheres to belt 14 and is ejected into trough 40, or is carried through the apparatus and ejected on to a desk 47. The exposed copy is conveyed by belt 13 to a further belt 49 which passes the copy to a development section 48 and ejects it into trough 54 or 56. The belts comprise either one perforated piece or several parallel strips, the original and copy being held on the belts by a vacuum created in the cross-hatched areas. The copying cylinder 16 has a diameter of less than 10cm. and is cooled by air from the outside via a slot die 44. The upper part of the apparatus including the belt 14 is pivoted at 58 to allow easy access to the cylinder.

Abstract: 1428810 F.H. receivers PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 6 June 1973 [9 June 1972] 26976/73 Heading H3R An f.m. receiver comprising means for blocking the signal channel during part of each time interval between successive zero crossings of the modulated signal in accordance with the modulating signal, is characterized in that the blocking means comprise: means for measuring the duration of the time intervals; means for storing the values of the measured durations; means for calculating the expected minimum duration of the next time interval from the stored values and from predetermined modulation data; and means for producing a blocking signal having a duration substantially equal to said calculated expected value. The received f.m. signals at 1 are fed to AND gate 7 and to a unit 2 which measures and stores the value of a time interval T n . At the same time, the value of a previous interval T n-1  stored in 2 is transferred to store 3, and the value of the preceding interval T n-2  is transferred from store 3 to store 4. The outputs from the three stores, and the values of the maximum modulating frequency and peak frequency deviation are fed to computers 5, 6 which calculate the expected minimum and maximum values respectively of the next time interval and computer 5 produces an output signal to open gate 7 a short time before the next zero crossing is expected. If no such crossing occurs before the maximum calculated time, computer 6 produces a substitute output which is fed to detector 9 and which also initiates the next blocking period. Instead of being produced directly by the computers, the control signals may be produced by mixing the received signals with auxiliary signals whose frequency is controlled in accordance with the calculated values, and deriving sum and difference frequencies, Fig. 3 (not shown).

Title: Improvements in or relating to the production of alkali metals
Inventor: SZECHTMAN JOSHUA
IPC: C25C3/02
Filed: 1962-07-13
Abstract: <PICT:1013004/C6-C7/1> An alkali metal vapour such as of Na or K is produced by electrolysing a fused alkali metal salt, e.g. NaCl or KCl, in the presence of a molten lead cathode which both flow through a horizontal electrolytic chamber, the fused salt on top of the molten lead, below the anode or anodes of an electrolytic cell, to form a molten alkali metal-lead alloy generally containing 10-50% of alkali metal, withdrawing the molten alloy from the electrolytic chamber and passing it into a vaporizer, e.g. where it is either heated or subjected to a partial vacuum, to evaporate the alkali metal from the alloy. As shown, an elongated electrolytic cell body 12 contains the molten lead cathode 16 supplied through conduit 80 and fused salt supplied through conduit 82 with anodes 50 supported by stems 52 in the electrolytic chamber 17 from a graphite cover 30; interior channels are provided in the anodes and cover e.g. for withdrawing chlorine.  The cell body 12 may be heated by means of molten lead circulating through longitudinal conduits 20 communicating (means not shown) with molten lead 46 in the circumferential channel 34 which is fitted with a corresponding flange 42 for hydraulically sealing the chamber 17.  The cover is electrically insulated from the cell body by an insulating sheet 61, the interior of the chamber 17 being insulated by refractory lining 60.  The end compartment 89 of the chamber contains a cylindrical sleeve 94 having apertures 95 through which the alloy formed is discharged to pass through the nose 96 of the sleeve 94 to a vaporizer 120 preferably fitted with a cyclone separator 121.  After a proportion of the alkali metal has vaporized away through conduit 122 from the cathode stream in the vaporizer, the remaining alloy is returned via a fuser 130 back to the cell.  For producing potassium vapour, CaCl2 may be added to KCl to lower the melting-point of the electrolyte e.g. to 720 DEG C., so that the alloy need be heated to only 760 DEG C. in the vaporizer. Specifications 986,223, 1,007,778 and 1,011,819 are referred to.

Abstract: 359,647. Thermometers. STALLAN, W. J. and CAMBRIDGE INSTRUMENT CO., Ltd., Chesterton Road, Cambridge. Sept. 11, 1930, No. 27123. [Class 97 (iii).] The circuit to a signal to. be actuated at a temperature which is a predetermined amount below the boiling point of water includes two contacts one of which is moved in accordance with the temperature by a vapour pressure thermometer compensated for atmospheric pressure variations, the other being moved in accordance with a predetermined law for instance the law connecting the alterations in the boiling point of water with changes in atmospheric pressure. In the form shown a bulb 1 containing a vaporizable liquid is connected by a pipe 2 to the interior of a Bourdon tube 7. The free end of the tube 7 is connected by a link 9 to a lever 10a the other end of which carries a toothed segment 10 driving the spindle 13 carrying the pointer 14. The pivot 11 of the lever 10a is carried by a frame 19, 20 rotatable about the spindle 13. A sealed evacuated Bourdon tube 8 is adapted to compensate for variations of atmospheric pressure by rotating the frame 19, 20 thus moving the pivot point of the lever 10a. A relay device for actuating audible or visible signals when the temperature reaches a predetermined number of degrees below the boiling point of water irrespective of atmospheric pressure is operated when a contact 41 fixed to the segment 10 and thus moving proportionately to the temperature of the bulb 1 touches a contact 32 carried by a pivoted cranked lever 33, 35 caused to rotate proportionately to the atmospheric pressure by the engagement of the arm 35 with a member 36 attached to the free face of an aneroid diaphragm 37. The device is suitable for indicating the temperature of the cooling systems of aircraft engines.
