Title: Improvements relating to the manufacture of transposed multiple strip conductors
Inventor: BENNETT PETER IAN
IPC: H01B13/02
Filed: 1962-06-05
Abstract: 969,086. Transposed conductor stranding machines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 27, 1963 [June 5, 1962], No. 21702/62. Heading H1A. The invention relates to apparatus for producing transposed multiple strip electrical conductors in which an odd number of and at least five insulated conductor strips are arranged in two juxtaposed stacks and the conductor strips are displaced successively from one position to another in the stacks along the length of the conductor. A transposing head for this purpose comprises a casing 1 having a central opening 3 longitudinally through which the conductor comprising strips 31 passes; symmetrically disposed about the opening 3 are four rotatably driven shafts 5, each of which carries a cam 12 adapted by means of a cam follower 19 to control the radial movement of a sliding tool-holder 21, 24 and tool 24<SP>1</SP>. The four tools act upon the four corner strips of the conductor. The cams 12 are splined to the shafts 5 so that the relative angular positions of the cams may be altered. The cam followers 19 comprise sleeves mounted rotatably on further eccentric sleeves splined to shafts which are rigidly connected to the sliding tool-holders 21; the splined connection in this case provides for adjustment of the eccentricity of the sleeve and thereby of the degree of movement of the tools 24<SP>1</SP>. Thus the transposing head can accommodate varying sizes and total numbers of conductor strips. The tools mounted on either side of the opening 3 serve to transpose a single conductor strip from one stack to the other while those mounted respectively above and below serve to effect vertical shifting of the stack after the transposition of a single strip. The tool holders of the latter pair are mounted to swivel in a horizontal direction during the transposition of a single strip by one of the other pair of tools. Adustably spaced inlet and outlet guides (not shown) are provided to control the movement of the conductor through the opening 3 and supply reels (not shown) for the conductor strips move in an orbital path about the transposing head.

Abstract: 401,628. Picture frames and mounts. MACMILLAN & CO., Ltd. and HEATH, R. J., 10, St. Martin's Street, Leicester Square, London. Aug. 4, 1933, No. 21978. [Class 11.] In a frame and mount for displaying a series of pictures with relatively small margins one at a time so as to present the appearance of fullsized mounted pictures, the mount, or the backs of the frame, or both are recessed so that the picture may be slid in between the mount and the back of the frame and rests on the non-recessed part of the mount. The assembly shown in Fig. 1 comprises a frame 2, mount 3, and back 5, and the picture 7 may be slid between the mount and back by means of an opening 8 in the side, top, or bottom of the frame, and lies in a recess 6 of the mount and is thereby properly positioned. A recess 9 in the back permits gripping of the picture for withdrawal. Thus, although the picture has only a narrow margin 10 and is little larger than the opening in the mount, it presents the appearance of a fullsized mounted picture. The recess 6 may be wholly provided in the mount 6, or partly in the mount and partly in the back 5, or wholly in the back 5, and in each case may be formed by a hollowing of the mount or back or, as shown in Fig. 5, by a structure comprising two laminµ. A guiding strip 12 of celluloid or like material may be provided to guide the edge 7a of the picture under the edge 3a of the mount.

Title: Improvements relating to cutting or abrading tools
Inventor: BEARD ALBERT
IPC: B23D73/00
Filed: 1957-07-11
Abstract: 839,401. Making cutting-tools; shearing; shear-blades; milling-cutters. SIMMONDS AEROCESSORIES Ltd. June 17, 1958 [July 11, 1957], No. 22018/57. Classes. 83 (2),.83 (3) and 83(4). [Also in Group XXIII] A method of making a cutting element by slitting hardenable sheet-metal and displacing one edge of each slit to form a cutting-edge, wherein each cutting-edge is produced in at least two separate punching, operations, the first operation deforming a portion of the sheet towards one side thereof and the second operation shearing away a. section of said portion to provide an edge, the position of the remaining part in relation to the sheet is unchanged during shearing. A mild-steel strip 3 is fed intermittently through a two-stage punching machine, first-stage punches 4 and dies 5, Fig. 1, acting to slit the strip and form a series of tongue-portions 8, the tongues being staggered in adjacent rows. Second-stage punches 17 coact with dies 15, Fig. 3, to shear off each forward-edge part 9 of the tongues, and so form cutting-edges 25. The resulting edges have a clearance.angle c of about 30 degrees and an edge projection D of 0.04 ins. An edge projection of 0.02 ins. may be obtained by inclining each tongue from root to tip in the first punching stage, after which each tongue is sheared off, halfway along its length. Positive rakeangles R<SP>1</SP>,Fig. 5, are obtained either by punching on an incline or by displacing the edge 25 back towards the strip 3. In a modification, the edge 25 is displaced further back towards the strip 3 than the final required position, the edges are ground parallel to the strip, and finally the edge is again displaced away from the strip to give a clearance-angle of 10 degrees, a rake-angle of 15 degrees and an edge-projection of 0.015 ins. In a further modification the first-stage punches 41 and dies 44, Fig. 8, form deformations 45, and the second-stage punches 48, Fig. 9, remove the apices of the deformations, after which the tongues 49, 50 are displaced back towards the strip by different amounts so that edge 52 forms the cutting-edge and the tongue 50 forms a rubbing surface. The clearance and rake angles are each about 15 degrees. Alternatively the punches may be inclined or may be eccentric to the apex, and ground-edges may be provided as before described. The formed-strip may be bent half-round or formed into a drum. Disc-form cutting elements may also be produced.

Filed: 1937-08-10
Abstract: 490,716. Impedance networks. FABBRICA ITALIANA MAGNETI MARELLI. Aug. 10, 1937, No. 22038. Convention date, Aug. 11, 1936. [Class 40 (iii)] In a circuit which is intended to be antiresonant between the points 1, 2 at the frequency at which a crystal Q contained in it is resonant, the crystal is connected to an inductance L and capacity C so as to form a closed mesh, and exact coincidence of the resonant and anti-resonant frequencies is secured by connecting the external circuit to a tapping 1 at the centre of an inductance L1, a resistance, Fig. 4 (not shown), or a divided capacity, Fig. 6 (not shown). The two halves of the coil L1 are magnetically coupled so that they neutralize one another's reactance between the points 3, 4. When a resistance is used instead of the inductance L, it should have the value #(L/C). The inductance L1 may be shunted by a condenser, Fig. 7 (not shown), which, together with the inter-electrode capacity of the crystal Q and inductance L1, forms an arm which is antiresonant at the frequency at which the inductance L would be resonant with the capacity C. In a further modification, Fig. 8, one of the external connections is made at a point 1 between two equal crystals Q1, Q2.

Patent GB-423865-A (GB)
Title: Improvements in the manufacture of aliphatic anhydrides
Filed: 1933-08-09
Abstract: The anhydride vapour mixture from the thermal decomposition of the corresponding aliphatic acid is brought into contact with additional liquid or vaporized aliphatic acid or anhydride under such conditions that the water and, if desired, some or all of the acid, is maintained in the vapour form.  Preferably, the addition is anhydride containing up to 20 per cent of acid, which converts any ketene in the vapour into anhydride.  The quantity of added acid or anhydride may be equal to or up to ten times the quantity of acid thermally treated.  The condensation of the anhydride may be simultaneous with the addition of the acid or anhydride, or a mixture of the reaction vapours with added vapour of acid or anhydride may be fractionally condensed as described in Specification 279,916, [Class 2 (iii)], and if desired an entraining agent such as a hydrocarbon or chlorinated hydrocarbon may be employed to facilitate the separation of the water vapour from the anhydride.  The thermal treatment of the acid may be effected in presence or absence of catalysts, and the acid may be preheated for example by boiling it under pressure or by superheating by means of superheated steam or by passage through molten baths. Acids mentioned are acetic, propionic and butyric acids.
