Title: Carcass tying machine
IPC: A47J43/18
Filed: 1961-08-16
Abstract: 985,822. Trussing birds &c. GORDON JOHNSON CO. Aug. 16, 1961 [June 20, 1961], No. 29505/61. Heading A2U. [Also in Divisions B3, B8 and F2] A machine for trussing a carcass comprises means for supporting the carcass with its legs in an outstretched condition; means adjacent said supporting means to bring the legs together and means for looping a securing member round the legs. The carcass, e.g. an eviscerated bird 420, is placed on the table 28, Figs, 1, 2 and 9, between a pair of guides 422, 424 with the tail 428 of the bird positioned below a plate 68. The plate 68 is lowered automatically to clamp the tail and a pair of needles 118, 120 are, passed upwardly through the bird adjacent the tail by means of a pneumatic assembly 126. The needles cross just below the table 28 and then pass through apertures 132, 134 (Fig. 3). A wire tie (Fig. 12) has its looped ends 140, 142 positioned one above each of the apertures 132, 134; the U-shaped portion 138 of the wire having been previously passed through a slot 136 which interconnects the apertures. The needles have pointed ends which engage in the loops and convey the tie upwardly and through the bird and pass the looped ends of the tie between pairs of plates 204, 206 located on a member 188 (Figs. 1, 5 and 6) which are spring pressed towards each other and which prevent downward movement of the tie when the needles are withdrawn. A pair of probes 160, Figs. 1 and 2, on a pneumatic assembly then pass upwardly to impale the bird and retain it in position while an arcuate edged plate 94 is pneumatically lowered to move the ends of the legs 426 from a position where they are pressing against the plate 62 between a pair of guides 64 to a position adjacent the tail. The tie is folded round the tail and legs and the ends of the tie are twisted together to truss the carcass 420, Fig. 11). The twisting device, Figs. 5 and 6, includes a rod 178 which rotates about a substantially vertical axis and has an enlarged head from which pins 186 project. The rod is rotated by a rack 228 on a bar 226, which is reciprocated longitudinally by a pneumatic piston and cylinder assemblies, the rack meshing with a pinion 234 attached to the rod 178. With the ends of the tie held between the pairs of plates 204, 206 a pair of blocks 190 are moved from opposite sides towards the head 184 to move in the looped ends 140, 142 of the wire. The ends are engaged by the pins 186 and twisted together. The various pneumtic assemblies are controlled by electrically-operated solenoid valves (Fig. 13, not shown).

Abstract: 298,237. Halperin, H., and Miller, K. W. Oct. 6, 1927, [Convention date]. Transmission conductor arrangements; protective arrangements. - Means for reducing the induced voltages in electric cable sheaths; particularly on underground three-phase transmission cables, consists in dividing the sheaths into lengths by insulating joints, and bridging each set of joints by reaction coils, a single reactor being used having coils severally connected to the sheaths of the cables so as to act in flux opposition. In the embodiment shown in Figs. 1 and 3, each cable has a lead sheath 2 divided into insulated sections by joints 3. A reactor has iron cores 5 magnetically closed by members 4. Coils 6 are mounted on the respective cores, and are earthed at their centres by a wire 8 which earths all the cores. The coils 6 are similarly wound, and the member 4 is also earthed. The coils 6 bridge the joints 3, Fig. 1, and are connected in series with the sheath lengths of the respective cables. In a modified construction, the coils 6 are earthed at the ends, the sheath lengths being transposed by bonding as shown in Fig. 2.

Title: Improvements relating to aeroplane wings
IPC: B64C3/14
Filed: 1934-10-18
Abstract: 446,094. Aeroplane wings. MESSERSCHMITT, W., 118A, Haunstetterstrasse, Augsburg, Germany. Oct. 18, 1934, No. 29848. Convention date, April 14. Drawings to Specification. [Class 4] In an aeroplane wing in which all sections have their maximum thickness at approximately one third of the wing chord, the form of the leading edge of the wing is varied along its span so as to present one or more relatively sharp edges toward the centre of the span. When the wing is of constant chord and thickness, the radius of curvature of the leading edge may be progressively diminished from the tip of the wing to its centre where the radius of curvature may be zero over a portion of the span. If the wing is of varying cross-section, the radius of curvature at the centre portion of the span is less than that of a section having the same chord and a section geometrically similar to that at the wing tips and in this case the decrease in the radius of curvature may not be absolute. The relatively sharp leading edge may be achieved by securing to the wing over a central portion of its span ribs or fillets of pointed section. Alternatively, a groove or a pointed, stepped, projection may be formed at the central portion of the wing span.

[Class 94 (i)] [See also Group XI] Relates to mechanism for sealing the folds of packages by the application of heat, and for cooling the heated seals. The wrapped packages P are advanced in succession along a bottom plate 53 between end folding plates 52 and emerge between sealing belts 23 and delivery or cooling belts 54. The belts are driven from a shaft 13 connected with the main drive through gears 15, 17, 20. The belt 23 passes round a driven pulley 22 and an idler 24, the shaft 25 of which is mounted in a slot 44 and carries adjusting screws 46 resiliently urged by screws 46a to tension the belt and to allow for variations in length when heated. Heating elements 41 are disposed between the runs of the belt, the support 39 having an aperture 42 to admit wires 43. Heat insulating pads 47, 48 prevent outward radiation of heat, and the shafts 21, 25 may have heat resistant bushings 49. The belt 23 comprises a flexible metallic sheet of flattened wire coils 50, Fig. 5, interlocked by means of transverse rods 51. The delivering belts 54, which may be cooled, are similarly mounted and constituted. The housings 26 which enclose the belt supporting mechanism, are mounted for lateral adjustment by oppositely screw-threaded spindles, to accommodate packages of different sizes. The belts 54 may be cooled by means of an expansion coil within a brine tank mounted between the runs. In a modified construction for heating the belts 23, a primary winding 56, Fig. 6, is wound about one leg of a transformer core 57 which extends between the runs of the belt, which itself constitutes a secondary winding having a single turn. Current is thereby induced in the belt, which becomes heated. The pulleys 22, 24 are insulated or made of insulating-material.

Ornamenting. - Letters, signs, and the like are formed by suitably arranging a number of prismatic reflectors formed as rightangled tetrahedra, which reflect incident light back towards its source. Thus a lens b, Fig. 8, adapted to render the reflected beams slightly divergent, is formed at its back with six rightangled tetrahedra a, silvered or not, and a number of reflectors so constructed can be mounted by means of stems d so as to form a letter or the like. Alternatively the tetrahedra may be stamped or pressed from a strip of sheet metal and secured to the inside of a sheet of plate glass e, Fig. 2. A number of glass tetrahedra may be mounted on the back of a sheet of plate glass to form a pattern, or they may completely cover it as shown in Fig. 5, a stencil being provided to mark out the letter as a light or a dark patch. The reflectors may be illuminated from behind instead of from in front. The interior of the sign may be coated with paint or tin foil or reflecting material, with the exception of a part left transparent to admit daylight and of the prisms forming the required letter or the like, or a skylight may admit daylight to the interior of the sign. The optical surfaces may have irregularities to spread the emergent light. One Provisional Specification describes reflectors made of wood coated with gold leaf paint, lacquer or the like, and also a method of forming letters out of a V-shaped groove in a wood or sheet metal surface, the prisms being made up as to one side from a side of the groove and as to the remaining sides from a shaped metal strip.
