Patent GB-864413-A (GB)
Title: Improvements in or relating to telephone systems
Inventor: DENBY JAMES FREDERICK
IPC: H04Q3/42
Filed: 1956-09-06
Abstract: 864,413. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Aug. 9, 1957 [Sept. 6, 1956], No. 27255/56. Class 40 (4). [Also in Group XL (c)] A circuit for checking that the stored dial digits in a two out of five code are correctly transferred from the store, comprises a number of comparison circuits, each including four normally non-conducting gas tubes RL, RC, EL, EC and two input lines R and C to which a stored digit is applied before and after transfer respectively. In the absence of both digit signals, the application of a testing pulse at terminal CP causes tube CS to fire and thus to fire tube PU. The output pulse from this tube is applied to two tubes RC and EC but as these are normally back-biased they do not fire and an alarm relay ALR does not operate. If a digit pulse had previously been applied to terminal R, tube RS would have fired causing tube RL to be back biased and RC to be primed. Accordingly, the testing pulse would have caused RC to fire and this would have caused a normally primed tube EL to fire. This tube is connected to a further tube AL which also would have fired causing the alarm relay ALR to operate and indicate an incorrect transfer. In a similar manner, if a pulse had been applied to terminal C before the testing pulse the alarm would also have operated. If pulses had been applied to both R and C, tubes RC and EC would both have been primed but RL and EL back-biased. Accordingly, the testing pulse would have caused RC and EC to fire but this would not have caused RL and EL to fire and the relay would not have been operated. For the whole two out of five system, twenty circuits such as are in Fig. 1 would be provided, one input lead of each being connected to a lead in the store and one to the comparison point. The testing pulses would be received through a common tube CS supplying four tubes such as PU, each supplying five comparison circuits. These circuits would all be connected to a common alarm relay (Fig. 2, not shown).

Patent GB-603321-A (GB)
Title: Target direction finding apparatus
IPC: G01S1/02
Filed: 1945-10-22
Abstract: 603,321. Photo-electric apparatus for direction finding. FARNSWORTH TELEVISION & RADIO CORPORATION. Oct. 22, 1945, No. 27764. Convention date, Sept. 29, 1944. [Class 40 (iii)] [Also in Group XL (a)] In a direction-finding system, light from a target is projected, with intermittent interruption, on to a photosensitive cathode in such a manner as to produce a circular trace the location of the centre of which is representative of the target direction. In Fig. 1, the photo - sensitive cathode 12 of a photocell is divided into quadrants I, II, III, IV (see also Fig. 2), contained-in an evacuated envelope 11. Light from a distant target is projected on to the cathode through a lens 25 mounted eccentrically in an otherwise opaque disc 26 (see also Fig. 3), which is rotated about an axis common to the photocell to produce a circular trace 33 (see Fig. 2), the position of the centre 34 of which is representative of target direction relative to the common axis. To discriminate between the standing currents of the photocell and those due to the target the latter are made intermittent by arranging a disc 27 containing alternate opaque and transparent sectors to rotate with disc 26 (see also Fig. 3) and fixing a similar stationary disc 30 (see also Fig. 4) on the common axis between the lens carrier and the photocell. Each cathode quadrant is associated with an electron multiplier, e.g. 13, 14, the electrode potentials of which are supplied by separate sources, e.g. 17, 18. The A.C. components of the voltages across electron multiplier load resistances, e.g. 19, 20, are applied through capacitors, e.g. 23, 24, to amplifiers, e.g. 20, 21. The relative outputs of the four amplifiers are thus dependent on target direction and are equal if the target is on the common axis. The following modifications are referred to : (a) a single supply source for the electron multiplier electrodes; (b) tuned circuits resonant at the interruption frequency in place of the resistive loads of the electron multipliers; (c) division of the photo-sensitive cathode into a number of segments other than four; (d) operation without electron multipliers ; (e) positioning of the interrupting discs between the target and the lens.

Title: Improvements in and relating to the assembling mechanism of typographical composing machines
IPC: B41B11/18
Filed: 1935-10-09
Abstract: 455,064. Type-bar-making machines. WALKER, V. E., 9, Kingsway, London.- (Mergenthaler Linotype Co. ; 29, Ryerson Street, Brooklyn, New York, U.S.A.) Oct. 9, 1935, No. 27844. [Class 100 (iii)] Assembling matrices.-In machines having means for assembling matrices at either of two levels, the assembler elevator is arranged to be vertically adjustable, so that the assembly level of the matrices can be kept constant in relation to the axis of the star-wheel whether the matrices are being caught in the upper or in the lower position. It is thereby ensured that all the matrices are straightened into the vertical position by the star-wheel as they enter the assembler. The assembler has, as hitherto, a movable rail 40, Fig. 1, operated by a finger-lever 51, for supporting matrices in the upper position, the rail having a short independently movable section 41 at the receiving end, to enable mixed lines to be composed. The assembler is supported by an arm 52, Fig. 3, pivoted to it, and having at the lower end a roller 54, adapted to rest in either of two recesses 55, 56 at different levels in the face of a supporting cam 57. The cam is vertically adjustable on the machine frame, so as to enable the initial position of the elevator to be adjusted. The arm 52 is operated by means of a knob 66, to shift the roller 54 from one to the other of the recesses 55, 56, and thereby raise or lower the elevator through a distance equal to that between the two assembly levels. The arm 52 also operates the short rail section 41 through an extension 67. The spaceband buffer 77, which is engaged by grooves in the lower ends of the spacebands, is vertically adjustable with the assembler. The buffer is carried by a slide mounted on the machine frame, and is depressed by the assembler against the action of a spring.

Abstract: Diamines of the general formula <FORM:0673633/IV (b)/1> (wherein R1 and R2 each represent hydrogen or an alkyl group of 1-4 carbon atoms, or R2 may also represent chlorine, bromine or iodine, A represents an alkylene group of 2-11 carbon atoms, and R3 and R4 represent alkyl or aralkyl groups or may be joined to form a ring, and together contain a total of not more than 11 carbon atoms) are manufactured by treating at reaction temperatures, in the presence of a solvent which is or contains an acid-binding agent, an a -pyridyl-a 1-thenylamine with an o -R3,R4-aminoalkyl halide.  Preferably the halide is a chloride and the reaction is carried out in an inert hydrocarbon solvent (e.g. benzene, toluene, xylene or petroleum ether) in the presence of an alkali metal (e.g. sodium) amide or hydride.  The products are useful as chemical intermediates, and in some cases themselves possess physiological activity, e.g. some have antihistaminic and antispasmodic and some local anaesthetic properties.  They may be converted into salts (e.g. hydrohalides, sulphates, phosphates, oxalates, succinates, fumarates, maleates, tartrates, gluconates, citrates or picrates) and quaternary ammonium compounds.  Examples and a list illustrate the following meanings of the various symbols: R1=hydrogen and g -methyl, R2=hydrogen, b 1-methyl and a 11-bromo, A = -(CH2)2-, -(CH2)3-, -(CH2)11- and -CH2-C(CH3)2-CH2-, R3=methyl, ethyl or n-butyl, R4= as R3, or benzyl, or R3+R4+N = piperidino or morpholino.  Specification 606,181 is referred to.  a  - Pyridyl - a 1 - thenylamines of the general formula <FORM:0673633/IV (b)/2> are manufactured by reacting an appropriate a -aminopyridine with an appropriate a -halomethylthiophene, or with an appropriate thiophene-a -aldehyde in the presence of a reducing agent (especially formic acid), or by reacting an appropriate a -halopyridine with an appropriate a -thenylamine.  Examples describe the preparation of a -pyridyl-a 1-thenylamine and N - (a  - pyridyl) - N - (a 11 - bromo - a 1 - thenyl) amine.  Thiophene-a -aldehydes of the general formula <FORM:0673633/IV (b)/3> are obtainable by reacting a thiophene compound (e.g. a -bromothiophene) with an N-substituted formanilide (e.g. N-methyl-, N-ethyl- or N-phenyl-formanilide) in the presence of phosphorus oxychloride.  The Specification as open to inspection under Sect. 91, comprises also the manufacture of compounds of the general formula above in which A may be a hydrocarbon radical other than alkylene, and R3 and R4 may be hydrogen, and the use of the processes of Specification 672,872 and of the additional processes described in that Specification (as open to inspection under Sect. 91).  Additional examples are given.  This subject-matter does not appear in the Specification as accepted.
