Title: Improvements in or relating to data storage devices
Inventor: BREWSTER ARTHUR EDWARD
IPC: G11B23/12
Filed: 1961-11-16
Abstract: 982,330. Friction clutches; clutch control. STANDARD TELEPHONES & CABLES Ltd. Nov. 9, 1962 [Nov. 16, 1961], No. 10012/64. Divided out of 982,329. Headings F2C and F2L. A clutch, operable intermittently to transfer the continuous rotation of a drive-shaft 60 to a sprocket 64 feeding a data-storage record tape (see Specification 982,329) includes a detent wheel 67 engageable by solenoid-operated means X to lock it, the action loosening a helical spring 69 whose normal mode is wrapped drivingly about the shaft to rotate the detent wheel and sprocket together. A sprocket pin 68 is permitted limited rotational freedom in a circumferential slot 97 in the detent wheel 67 and when the wheel is held by the means X, further drive of the sprocket 64 and the spring 69 in the direction 96, brings the free end of the spring into contact with a detent wheel abutment 95, further sprocket movement uncoiling the spring 69 out of driving engagement with the shaft. The spring 95 is ground out to a tapered bore after winding so that the unattached end near the detent wheel first engages the shaft when the detent wheel is released. For "fail-safe" purposes, the operating solenoid (Figs. 5, 6, not shown) has a hand engageable latch to hold the armature in the position assumed when its coil is energized, preventing inadvertent tape-feeding when the machine as a whole is switched on. Specification 982,329, [Division G5] describing recording and playback details is referred to.

Title: Improvements in, or relating to, magnetically operated electric switches
IPC: H01H50/22
Filed: 1935-04-04
Abstract: 452,598. Electromagnets. CRABTREE, G. E., Endwood, Little Aston Park, Sutton Coldfield, ELLIOTT, W. T., The Vicarage, Grosvenor Mount, Leeds, BADHAM, E., 34, Buchanan Road, Walsall, and THORNTON, R. W., 3, King Edward Street, Oxford, [Representatives of CRABTREE, J. A.].-(Schiele & Bruchsaler Industriewerke Akt.-Ges. ; Baden- Baden, Germany) April 4, 1935, No. 10433. [Class 35] [See also Group XXXVII] In order to receive the impact on the laminated core or armature of an electromagnet adapted to be used in an electromagnetic switch, rigid mechanical resistance members are so assembled in grooves or channels in the core or armature structure that they substantially relieve the rivets holding the laminations together of such operating or impact stresses. As shown in the Figure the resistance members comprise rectangular section steel bars 7 which are inset in grooves formed in lateral extensions of the E-shaped relatively fixed core 1. The members 7 are thus outside the main flux zones of the core structure and the rivets can be disposed in widely-spaced relationship and in magnetically neutral zones so that no eddy-current-producing magnetic flux passes between any two of said rivets. The core member 1 is pivotally supported from a stirrup-shaped support 9 by pivot studs 8 and extensions 11 of these studs enter recesses in the core to prevent lateral displacement of the resistance members 7. The operating coil 13 is suspended from cross struts 10 mounted between the arms of the stirrup member 9. The armature 2 is pivotally attached at 3 to the end of a guided rod 4 passing through a gland in an insulating plate on the remote side of which are the switch contacts. The pivoting of armature and core about planes respectively at right angles permits a self-aligning action to take place between their engaging faces.

In order to avoid formation of images of the filament in the zone 18 the front or rear face or both faces of the lens 16 has or have vertical cylindrical flutes 26. Rays are prevented from passing directly from the filament 13 to the zone 18 by a metal shield 14. The lens 16 may be of blue-green heat absorbing glass, and the reflector 12 may, alternatively, be formed by two co-axial spherical surfaces of differing radii as in a Mangin mirror.
Patent GB-1013463-A (GB)
Title: Phosphonitrilic compounds
Inventor: LUND LARS GUNNAR
IPC: C08G79/025
Filed: 1961-11-23
Abstract: The invention comprises cyclic phosphonitrilic halidates of the general formula [PN(OR)xXy]n, wherein each R is an aryl group, optionally containing alkyl and/or chlorine substituents and which may be the same or different, X is a fluorine, bromine or chlorine atom, n is an integer of from 3 to 17 and x and y are numbers which may be fractional such that x + y = 2 and y has a value of 0.6 to 1.1. They may be obtained by reacting a cyclic phosphonitrilic halidate of the formula [PN(X)2]n, wherein X and n are as defined above with one or more metal aroxides in a molar amount of from 0.9n to 1.4n per molar proportion of phosphonitrilic halide and then separating the phosphonitrilic halidate product from the metal halide formed therewith, the reaction being carried out in an inert diluent. The reaction may be effected by heating and the inert diluent should generally be a solvent for the phosphonitrilic halide and for the halidate formed but not for the metal salt produced in the reaction and specified diluents are liquid hydrocarbons such as benzene, toluene and petroleum ether, and chlorinated hydrocarbons such as methylene chloride, chloroform or carbon tetrachloride. In a preferred method of operation the inert diluent is one which contains at least 20% by volume of an aliphatic ketone, e.g. acetone, and the reaction temperature is controlled at between - 20 DEG  and + 20 DEG C. until the reactants are completely intermixed. Suitable metal aroxides are the Na, K, Li, Mg and Al phenate salts of phenol, cresols, xylenols, naphthols, and chlorinated phenol, cresols and xylenols.  Mixtures of aroxides may be employed and the phosphonitrilic halide may first be reacted with one aroxide and then with a second aroxide.  In the preferred process in which an aliphatic ketone is present, the ketone may be diluted with an aromatic hydrocarbon, e.g. toluene, in an amount not exceeding 80% by volume of the total diluent.  Improved results are obtained in the preferred process if the phenate salt is prepared in situ in the diluent from the phosphonitrilic halide, free phenol, and alkali, e.g. NaOH.  Examples are given for the production of  [PN(OC6H5)Cl]3, [PN(OC6H4Cl)Cl]3, [PN(OC6Cl5)Cl]3, <FORM:1013463/C2/1> wherein x, y and z are each 0.67, P3N3(OC6H5)4Cl2, [PN(OC6H5)1.33Cl0.67]3, [PN(b -OC10H7)1.33Cl0.67]3 and [PN(a -OC10H7)1.33Cl0.67]3.

Filed: 1943-07-06
Abstract: 566,747. Electrically-released switches. MIDLAND ELECTRIC MANUFACTURING CO., Ltd., and VICARY, A. W. July 6, 1943, No. 10969. [Class 38 (v)] The rearward extension c of one limb of a spring-controlled pivoted yoke f normally retains a pivoted, spring-controlled catch k, thereby maintaining a circuit for the operating electromagnet d of the movable contacts c. On overload in any phase, the current-heated bimetal strip m of that phase rotates the yoke f and lowers the extension e out of engagement with the catch k, so breaking the electromagnet-circuit and allowing the catch to rotate against an abutment q on a resetting push-piece p. When the extension e is restored by its spring o, premature contact with the catch is prevented by insulation r, which is moulded on or otherwise applied to one face and over one cage thereof, the circuit being only remade when p is depressed to re-engage k with e.
