Patent GB-272518-A (GB)
Abstract: 272,518. Bowes, W. H., and Ogden, J. W. June 8, 1926. [Convention date]. Franking-machines. - A postage meter machine is arranged to print either a single impression or two or more side-by-side impressions. The machine described is similar to that described in Specification 170,058, the general arrangement being the same as that in Fig. 1 thereof. The printing- roller, however, is replaced by segmental dies 2, 3, Figs. 4 and 13, angularly spaced apart on a shaft 5 when a single impression is required but adapted to be adjusted about the shaft to form a continuous printing-surface when two side-by-side impressions are to be printed. In the first case, the shaft 5 rotates 180‹ for each letter passing through the machine, and in the second case a complete rotation is allowed. The shaft 5 is rotated by a shaft 30P driven through a friction clutch, and the rotation is controlled by a stoplever 103, Fig. 3, carrying a roller 103<b>, which is moved into and out of the path of rollers 104<b> at opposite ends of an arm 104 fixed on the shaft 5, the stop-lever being oscillated by means of a reciprocating pin 8P actuated from the tripmechanism in the same way as the pin 8 in Specificalion 170,058. Each segment 2, 3 has four keyways 3<b>, Fig. 13, and the segments may be fixed in various adjusted positions on the shaft 5 by means of a vertically slidable ring 108<a>, Fig. 4, carrying keys 108 engaging a keyway in each segment and grooves in the shaft 5. The segments are connected respectively to sleeves 2<c>, 3<c>, which have cam grooves 2<g>, 3<g> engaging pins 109<b>, 109<bx>, Fig. 17, so as to lower plates 109, 109<x> into engagement with a roller above the roller 103b on the arm 103 and so hold this arm out of the path of the oncoming roller 104b. Only one segment may be adjusted at a time, because one plate 109 or 109<x> will be over the roller 103b and cannot be lowered. Counting-apparatus and limit-locking arrangements. Registering-mechanism is actuated from the shaft 5 by gears 100, 101, 11<a>, Fig. 3, as in Specification 170,058, and the limit-locking arrangement is similar except that a comb 6, which is moved about its pivot 6a when the counters zeroize, is connected by a link 110 to a lever 102 so as to move it against an arm 103<c> on the stop-lever 103 and so lock the machine; also, there is no units tooth on the comb so as to avoid damage which might be caused if the machine were printing two impressions and the number printed were one short of the limit.

Title: Improvements in or relating to the preparation of 1,2,3,4,7,7-hexachlorobicyclo (2.2.1.)-2,5-heptadiene
IPC: C07C17/25
Filed: 1956-09-10
Abstract: 1:2:3:4:7:7 - Hexachloro bicyclo-(2:2:1)-2:5-heptadiene (Compound B) is prepared by reacting a 5-halo-1:2:3:4:7:7-hexachloro-bicyclo - (2:2:1) - 2 - heptene (Compound A) with an alkali-metal hydroxide in a liquid reaction medium comprising a minor amount (e.g. approximately 0.1 to 15 per cent by weight) of water, a substantial amount (e.g. 10 to 40 per cent by weight) of an inert neutral polar organic liquid, and an inert non-polar organic liquid forming the balance, preferably with a maximum content of approximately 89 per cent by weight, the boiling point of the liquid reaction medium preferably lying between 50 DEG  C. and 200 DEG  C.  The non-polar organic liquid may be substantially immiscible with water but miscible with the polar liquid; advantageously the inert polar organic liquid is primarily an oxygenated organic compound and the inert non-polar organic liquid is an unsubstituted hydrocarbon.  The process may be combined with the recovery of Compound B by distillation of the ternary mixture to obtain either a solution of B in a non-polar liquid alone or in a non-polar liquid together with an aqueous phase.  In an example, Compound A is reacted with sodium hydroxide, containing about 5 per cent of water, in a ternary solvent comprising 39 per cent isopropyl alcohol, 2.1 per cent water and 58.9 per cent n-heptane by weight.  The solvent is distilled to remove all the isopropyl alcohol in the form of the ternary azeotrope of this system, additional n-heptane being added at the rate it is removed, and sufficient water added to provide an aqueous phase equal in volume to that of the n-heptane. The two phases are separated to yield a solution of compound B in n-heptane.  In further examples, the process described above is carried out with the following modifications: (a) n-heptane only is added to form a solution of B in n-heptane containing suspended solid inorganic salts which may then be filtered off; (b) the ternary mixture is allowed to distil slowly during the reaction, additional n-heptane and isopropyl alcohol being added to make up for the amounts of these two solvents lost and to maintain the water concentration in the ternary mixture at 2 per cent by weight; (c) the pressure and temperature are both increased; (d) the relative amounts of solvents forming the ternary mixture are varied.  Specification 714,688 is referred to.

Title: Improvements in or relating to methods of and apparatus for photographically recording sound waves
IPC: G11B7/00
Filed: 1931-10-12
Abstract: 384,742. Optical sound recording apparatus. RADIO CORPORATION OF AMERICA, 570, Lexington Avenue, New York, U.S.A.-(Assignees of McDowell, H. ; 780, Gower Street, Los Angeles, U.S.A.) Oct. 12, 1931, No. 28341. Convention date, Nov. 8, 1930. [Class 40 (ii).] Comprises a method of recording optical sound records which, when reproduced, will produce a minimum of " ground noise," by exposing a film to a light beam one side of which beam is varied in accordance with the current impulses corresponding to the wave form of the sound while the other side of the beam is varied by a rectified component of the current impulses to form an envelope for the recorded soundwave form. Electric current impulses from a microphone 11 are passed through amplifiers 13, 17 and a mixer 15 to actuate an oscillograph mirror 19 upon which impinges light from a source L after passage through an aperture Al and a lens GL. The reflected light beam is directed through the lens GL and an optical system O, which includes a light slit SL, on to the record film F to form a variable area record M. Interposed between the mirror 19 and the optical system O is an apertured shutter A2 which by its movement serves to reduce the width of the recording light beam to produce a record portion N on the film F. Coupled through a transformer to the circuit from the amplifier 17 is a two-stage amplifier comprising thermionic valves 21, 23, the output from which is supplied to a rectifier 25 and a direct current amplifier 27. The rectified and amplified impulses produced aresupplied through the windings 35 of an electrodynamic motor 37 to earth. A battery 40 supplies current to the coil 38 to produce the electromagnetic field of the motor 37 and the winding 35 is divided into two portions 33, 39 the centre tap being connected to the battery 41. Thus, the shutter A2 moves in proportion to the strength of the rectified current to intercept one side of the recording light beam and produce a record trace N which forms an envelope for the wave form of the sound record M. The Specification as open to inspection under Sect. 91 comprises also a modification wherein a second mirror may be substituted for the shutter A2, which mirror controls the position on the film of the image of a second light source. Alternatively, the motor 37 may be utilized to vary the size of the aperture Al or, according to a further modification, the beam of light after reflection from the mirror 19 may be reduced to narrow dimensions bv means of a condensing lens and passed through the aperture of a light valve. This subject-matter does not appear in the Specification as accepted.

[Class 108 (iii)] A resilient mounting comprises a plurality of plates 4 extending at right-angles to and through an opening in an outer plate 1 and connected thereto by rubber or like resilient material 6 which is vulcanized or-otherwise united to and extends from both faces of the plates 4 and has supporting wall portions united to and overlapping the upper and lower faces of the plate 1. The rubber thus supports the major portion of the load in shear, but heavy shocks or increases in load flatten the rubber so that the supporting force is increased by compression of the rubber portions overlapping the plate 1, which portions may be reinforced by loose fibres or may be of denser rubber. The Specification includes all the constructions described in Specification 482,188 as open to inspection under Seet. 91, in which the rubber is slotted or in spaced sections or provided with openings in order to reduce the shear resistance in a direction parallel to the face of the plate 1 and also two other constructions of resilient mounting not having these features. In one construction, two plates 4 and in the other construction four plates 4 are provided and a hole between each pair of plates permits the passage of a securing bolt. A single mounting is also shown supporting the rear end of a vehicle engine. U.S.A. Specification 1,996,210 is referred to.
