Title: Improvements in or relating to ring-bound books
IPC: B42B5/10
Filed: 1935-08-16
Abstract: 461,620. Making fastenings. TRUSSELL MFG. CO. Aug. 16, 1935, No. 23072. Convention date, Aug. 25, 1934. [Class 83 (ii)] [Also in-Group XV] A sheet binder for binding the leaves of printed or memorandum books consists of a continuous strip of wire bent in zigzag formation thereby forming prongs 50 which are bent into substantially ring form, the prongs each comprising pair of adjacent or spaced apart lengths 53a of wire joined at one end 52a and connected at their other ends by connecting portions 51a, the joined ends being so shaped with respect to the connecting portions that when bending the prongs to ring form, the ends 52a of the prongs can extend between the connecting portions 51a so as to intersect a straight line passing through the connecting portions, without causing adjacent limbs of the prongs to be pushed apart. After bending the wire into zigzag formation it is bent around slightly at the ends, as shown, and the leaves of the book to be bound, and a pair of covers if necessary, which are provided with filing holes or slots, are then threaded on the prongs 50. The bending of the prongs into ring form is then completed by suitable dies. The Specification as open to inspection under Sect. 91 comprises also an arrangement of dies for bending the prongs of the sheet binder into ring form. When the leaves and covers have been filed on the prongs, the latter are then placed between a pair of dies 72, 73, Fig. 19 (Cancelled), which are so disposed that their axes are not in alignment. When the dies are moved towards each other to bend the prongs, the ends 51, 52 will be caused to overlap, the relative movement of the dies being continued to an extent such that when they are released the ends 51, 52 will be in alignment with each other. The portions of the wire adjacent the ends 51, 52 are then bent between a further pair of dies such that a binder of substantially circular form is produced. The finished binder may have the ends 52 of the prongs extending between the connecting portions 51 to prevent the leaves from becoming detached therefrom. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 447,231, [Group XV].

Title: Process for manufacture of benzene hexachloride
Inventor: MILLER LEO ANTHONY
IPC: C07C17/38
Filed: 1952-09-15
Abstract: Benzene hexachloride is made by reacting chlorine with benzene so as to form a solid free solution of benzene hexachloride in benzene which may suitably contain 15-28 per cent by weight of benzene hexachloride, contacting this solution with aqueous sodium hydroxide, settling the aqueous phase, passing the benzene phase through a bed of inert fibrous material, e.g. fibrous glass, to coalesce traces of the aqueous phase, vaporizing the benzene and fusing the benzene hexachloride at an elevated temperature, then allowing it to cool and solidify.  In a preferred modification, chlorine is dissolved in a benzene solution containing 2-15 per cent of benzene hexachloride, in a quantity sufficient to give 15-28 per cent of benzene hexachloride in solution after reaction, the chlorine is reacted with the benzene, preferably in actinic light, the resulting solution is contacted in a centrifugal pump with an equal volume of an aqueous solution containing at least 3 per cent of sodium hydroxide, the aqueous layer is allowed to settle, the solution of benzene hexachloride in benzene is passed through fibrous glass to coalesce residual emulsified aqueous sodium hydroxide, which is separated off, the benzene is vaporized from the benzene hexachloride and the product is finally fused, cooled and comminuted.  An apparatus for carrying out the process in a cyclic manner is described and illustrated by drawings.

Title: Improvements in and relating to printing apparatus
IPC: B41J7/68
Filed: 1956-07-26
Abstract: 818,884. Selective printing. HEWLETT-PACKARD CO. July 26, 1956 [March 9, 1956], No. 23197/56. Class 100(4) Type-wheel machines; electromechanical type-actions; aligning for impression. A printing machine, described for use with electronic counters, comprises an electromagnetically controlled clutch 17, 18 Fig. 4, connecting a drive 14 with a number of type wheels 86, and electromagnetic locking means 91-94, Fig. 2, which selectively lock the associated typewheel 86 against rotation for a printing operation. The characters are locked in selected position by the sensing of a particular potential by a brush and commutator arrangement as described in Specification 818,883, and this potential, together with a source potential, representing a character to be printed, are compared in a coincidence device and after operating the clutch magnet 57 to initiate a printing cycle, the coincidence device releases the armature 89 of the electromagnet 92 so that members 94 engage in a detent 87 formed between characters. Operation of the clutch magnet 57, pivots the armature 53 and causes engagement of clutch 17, 18, rotates shaft 16 and through gearing, rotates a typewheel shaft 73. Friction clutches are included in each type-wheel 86 (see Specification 818,883) so that a cycle of operation is completed upon each operation of magnet 57, although various wheels have by now been locked in predetermined selected positions. Line-spacing mechanism. Rotation of the shaft 16, (Fig. 3, not shown), rotates a cam, oscillates a follower lever, and reciprocates a pawl to advance a ratchet wheel on a feed-roller shaft 151. Hammer-impression arrangements. A cam 257 on shaft 16 operates, via follower 252 and lever 251, a spring impacting platen 122. The type-wheel shaft 73 rotates twice to one rotation of the shaft 16 so that type-setting occurs in the first half of a print cycle and impression in the second half-cycle. Ink-ribbon mechanism. Automatic ink-ribbon reversing occurs when the tension in the ribbon bears on a stud 194, Fig. 5, and pivots a lever 202. This pushes a two-position bell-crank lever 223 into its other position which engages a collar 243 to longitudinally shift a shaft 212 so that a pinion drive from a gear 209 is changed from one spool to the other.

Abstract: 986,980. Screw-sockets. DIAMOND EXPANSION BOLT CO. Inc. June 15, 1962, No. 23229/62. Heading F2H. A one-piece anchorable screw-socket, e.g. of cast zinc alloy, has a tapered nut portion 22 with ribs 52 in positions corresponding to grooves 42 in a shell portion 20 into which the nut telescopes, Fig. 12, when the socket is anchored in its hole, i.e. when thin parts of a portion 24 interconnecting the nut and shell are fractured either by hammering the socket into its hole with the nut 22 resting on the hole bottom, Figs. 8, 9 (not shown), or by drawing the nut forward by turning a bolt in it, Figs. 10, 11 (not shown). The ribs 52 cause splitting of the inner end 26 of the shell 20 with separation of the sides 56, Fig. 12, of the ends of the grooves 42 in that inner end. The grooves 42 may extend only in the tapered inner end 26 of the shell 20 but are shown extending throughout the shell bore 31 which may be slightly tapered to facilitate die-casting. The shell end 26, for gripping the hole receiving the socket, may bear annular tapered surfaces or ribs to give a serrated profile and the nut 22 may be tapered right to the end face, Fig. 13 (not shown), instead of having a cylindrical end as shown. Ribs 38, Fig. 6, extend from a depth-indicating ring 34, Fig. 4, to the outer face 29 of the socket, and over a thickened mouth edge 32 they are of triangular form, Figs. 1, 13 (not shown). They prevent rotation of the socket in its hole. Specification 365,864 is referred to.

Title: Improvements in or relating to circuit arrangements for generating oscillations of sawtooth waveform
IPC: H01J31/04
Filed: 1938-08-08
Abstract: 517,839. Cathode-ray tubes. FERNSEH AKT.-GES. Aug. 8, 1938, No. 23396. Convention date, Aug. 7, 1937. [Classes 39 (i) and 40 (v)] The electron beam is deflected by electrostatic or magnetic fields across an output electrode, the surface of which comprises at least two areas having different secondaryelectron-emission properties, to produce potentials of saw-tooth waveform on the electrode. An electrode 7, across which a beam from the gun 2 is deflected, comprises areas 4, 6 having respectively secondary-electron-emission ratios of more than one and less than one. The surface 4 may be wedge-shaped, or may comprise adjacent strips having different secondaryelectron-emission ratios, the beam being suitably incidental on both strips to obtain the required secondary emission. An anode 5 is provided. The deflecting plates 3 may be supplied with sinusoidal voltage, or with a potential derived from that on the electrode 7 so that the arrangement becomes self-oscillating ; in this case the circuit components may be arranged within the tube. When used for television apparatus, the deflecting voltage on the plates 3 may be synchronized by means of the usual synchronizing impulses. The received television signal may be applied to the deflecting plates 3, the bias on which is such that the synchronizing impulses deflect the beam from the area 4 to the area 6. To shorten the flyback time, the synchronizing impulses may be arranged to cause the potential on the Wehnelt cylinder to become more positive to increase the beam current. To produce oscillations in opposite phase, two beams, or a beam of elongated cross-section, may be deflected across two adjacent strips, each of which may be connected directly to a deflecting plate of a cathode-ray tube. The discharge device may be arranged within the tube for which the sawtooth potentials are produced.
