Title: Automatic proximity fuses
IPC: F42C15/40
Filed: 1962-09-06
Abstract: 1395145 Proximity fuses TELEFUNKEN PATENTVERWERTUNGS GmbH 6 Sept 1962 [21 Oct 1961] 34257/72 Heading F3A A missile-borne proximity fuse arrangement is enabled, when the missile approaches its target, by providing current to the fuse from a battery. The missile 4 (Fig. 1) transmits a signal of frequency f 0  which is reflected back from the target 2 with a Doppler shift. In the missile, a transistorized transmitter/receiver 8 receives supply from a battery 10. A detonating signal is fed to the detonator 13 when the heat frequency resulting from heterodyning the received and transmitted frequencies reaches a predetermined value, e.g. zero. The invention provides for the circuit from the battery 10 to be closed by operation of a pre-set time switch, or by a switch controlled from the ground, or by activating the battery, when the missile reaches the vicinity of the target. The battery may be activated by means of a time-fuse which causes an acid-containing ampoule to be broken.

Title: Process for the conversion of hydrocarbons
IPC: C10G11/05
Filed: 1938-11-29
Abstract: 523,252. Cracking hydrocarbons catalysts. MOND, A. L. (Universal Oil Products Co.). Nov. 29, 1938, No. 34811. [Classes 1 (i) and 32] [Also in Group IV] Hydrocarbon distillates, including fractions from preceding catalytic or pyrolytic cracking processes are cracked at temperatures between 425‹ C. and 650‹ C. in contact with a catalyst prepared by producing from precipitated hydrated aluminium oxide and precipitated hydrated silicon dioxide by conjoint or separate precipitation, a wet hydrate mixture substantially completely free from combined and adsorbed alkali metal, drying the mixture, forming it into particles and calcining at temperatures above 427‹ C. Alternative methods of producing the catalyst are : (1) mixing solutions of soluble alkali metal silicates and soluble aluminium salts (including aluminates) to co-precipitate hydrated alumina and silica ; (2) separately precipitating hydrated silica by acidifying an alkali metal silicate and' hydrated alumina by treating a solution of an aluminium salt with a volatile basic precipitant, e.g., ammonium hydroxide, carbonate, sulphide or hydrosulphide, or an organic base ; (3) adding precipitated and purified hydrated silica to an aqueous solution of an aluminium salt and precipitating the alumina as in (2) above ; (4) adding precipitated hydrated alumina to an alkali metal silicate and precipitating the silica by addition of acid. In precipitating silica by any of the above methods the final pH value of the solution should be 3 to 10. The precipitates are freed from alkali metal ions by washing with hydrochloric acid or ammonia or its salts, filtered, dried at 115-150‹ C., formed into particles of about 5-16 mesh per cm<SP>2</SP> and calcined at 455-540‹ C. or higher. The catalysts so produced are sufficiently stable to stand repeated reactivation at 760-870‹ C. Examples are given of the preparation of a number of catalysts and their application.

Title: Improvements in machines for registering statistical and like particulars from cards
Filed: 1921-12-29
Abstract: 194,832. Bull, F. R. Dec. 29, 1921. Compiling and tabulating statistics mechanically.-In a machine for registering statistical and like particulars from perforated cards the adding mechanism consists of a mutilated toothed wheel having nine teeth rotating synchronously with the card feed, and a plurality of toothed adding wheels each of which is adapted to be released by an electromagnet so as to engage with that tooth on the mutilated wheel corresponding to the number of the perforation under the sorting brush; the selective mechanism comprises a number of arcs of contact plates each arc having a contact brush wiping over it and being provided with a single electromagnet, all the electromagnets of the arcs being coupled to a single switch so that only when all the magnets are energized is the switch closed to complete the adding-circuit (partially) or a sorting circuit. In the Figure the two arcs of contact plates are wired for perforations 7, 3 in the first two columns of the card, so that the adding mechanism will only add the characteristics in the last three columns of cards having perforations 7, 3 in the first two columns. The card is fed in the direction of the arrow and the contact arms c<1>, c<2> wipe over the arcs C<1>, C<2> from 9 to 0 synchronously with the card feed so that for a card perforated at 7 in the first column a circuit is completed through the brush V<1>, the drum H, battery K, arms c<1>, plate 7 and magnet R<1> so that the latter releases the first arm of the switch R. Similarly the brush V<2> through the perforation 3 in the second column actuates magnet R<2> so that the switch R is now finally dropped to make contact at G. The card is now in the position shown and on further rotation of the drum H, contact is first-made through brush T<3> and perforation 7 in the last column, battery K, arm c<1> arcuate plate B, and switch R so that the magnet F<3> is energized and releases its respective catch so that the adding wheel E<3> comes into engagement with tooth No. 7 on the mutilated wheel D having 9 teeth, the completion of the rotation of wheel D causing the wheel E<3> to add seven units to the counter. Similarly for perforations 6 and 4 in the 5th and 6th columns the hundreds and tens wheels E<1>, E<2> are released so as to engage with teeth Nos. 6 and 4 respectively of the wheel D. After the passage of each card through the machine all parts are restored to normal; instead of the switch R partially completing an adding circuit, it may complete a circuit through a sorting flap.

Filed: 1956-11-15
Abstract: 831,692. Electric tests. WAYNE KERR LABORATORIES Ltd., and CALVERT, R. Nov. 15, 1957 [Nov. 15, 1956], No. 35002/56. Class 37. The conductivity of a liquid in a tube 30 is measured by means of transformers 35, 36 having cores surrounding opposite limbs of the tube, the secondary of 38 being coupled through an adjustable standard conductance 40 to the primary of 36. The primary of transformer 35 is fed from A.C. supply 38. The arrangement is such that two signals are induced in antiphase in secondary 42, one by the direct coupling between the transformers through the adjustable standard conductance and the other through the liquid. The setting of the conductance when the detector 43 gives a null indication is thus a measure of the conductivity of tube 30 and the liquid in it in parallel. The test may be performed with the tube empty to give the conductivity of the tube alone. Errors are minimised if the conductivity of the tube is low. Glass and polythene are suggested. The apparatus may be calibrated with a liquid of known conductivity in the tube. The standard conductance may be connected to a variable tap on the transformer or to a potentiometer slider. Specification 695,058 is referred to.
