Title: Improvements in or relating to the skinning of animals
IPC: A22B5/16
Filed: 1965-11-03
Abstract: 1,117,656. Skinning pigs. S. C. JOWETT. 21 Oct., 1966 [3 Nov., 1965], No. 46511/65. Heading A2U. In a method of skinning a dead pig, whose body temperature has not been raised above normal, natural temperture, e.g. an unscalded, preferably uneviscerated pig, it is suspended head-downwards by its rear legs 3 between a conveyer 15 and anchoring means, such as a tensioning hook 9 hooked to the head 8 and secured to another hook fixed in the floor or ground. A blood-letting wound 2 is made in the throat, before or after the pig is suspended. An incision 4 is then made lengthwise through the skin, preferably centrally along the belly, from the wound 2 to a point 5 between the rear legs, and another, substantially transverse, encircling incision 10 is made through the skin, so as to pass through the wound 2, between the ears and eyes and over the top of the head. Two parallel incisions may be made instead of the single incision 4. Incisions 6 may be made, from the point 5, through the skin along the insides of the rear legs 3, e.g. to join incisions made around these legs near the hooves 7. Incisions may also be made along the forelegs to join the incision 10. Hooks or clamps (not shown), preferably clamps of the self-tightening or locking type, are then attached to the ears, and, if desired, to the skin just above the incision 10, and pulling forces, directed upwardly and lengthwise of the pig, are applied to said hooks or clamps, as by block-and-tackle or winding gear, to peel the skin off the carcase, e.g. during or after bleeding. The skin bordering the incisions may be flayed to facilitate removal. In an alternative method, the incised dead pig is suspended head-upwards on a hook passing through its jaw, and a downward stripping force is applied to the skin. In a further alternative method, the incised skin is anchored, and a pulling force is applied to the carcase, in a lengthwise direction, to pull the carcase out of the skin. Skin left on the head and neck may be cut away by hand.

Filed: 1972-10-16
Abstract: 1398171 Electret transducers INDUSTRIAL RESEARCH PRODUCTS Inc 16 Oct 1972 [8 Nov 1971 (2)] 47559/72 Heading H4J An electret transducer has a diaphragm 20 (Figs. 1, 3) with a central vibratable planar portion and a compliant surround 29. A support plate 23 has spaced supports 44 on its surface on which the planar portion of the diaphragm 20 rests. The support plate 23 preferably has perforations 34 and a dielectric film 28 is preferably formed on one surface of the support plate 23, on the interior surfaces of the perforations 34 and over the edge of the perforations 34 on the second surface. The film 28 is a P.T.F.E electret. Alternatively the diaphragm 20B (Fig. 6) functions as the electret, the film 28 being omitted, and a metal coating 24B being formed on the surface of the diaphragm opposite the support plate 23. The surround 29 is flexibly resilient to allow for some lateral movement of the diaphragm portion on the supports due to temperature, humidity or aging. The transducer of Figs. 1, 3 comprises a easing 13, either one or both of the portions 16, 18 having acoustic apertures (not shown). The motor assembly 12 is mounted on a bulkhead 15 having one or more apertures 30. Diaphragm 20 is of polyethylene terephthalate and has a metal layer 24 formed by evaporation. The surround 29 is also metallized to provide connection from layer 24 to electronics 37 on the underside of bulkhead 15. The surround 29 has a foot 40 which sits on the bulkhead 15 to position the diaphragm 20. The support plate 23 has a downwardly extending flange 42 which mounts on the bulkhead 15. The diaphragm 20 may be metallized on both sides to compensate for dimensional changes due to temperature, humidity and aging and to maintain the diaphragm in its initial plane (Fig. 4, not shown). The diaphragm may be formed of laminations (Fig. 5, not shown) and the surround may have fewer layers than the planar portion so that it is thinner. One of the planar laminations may be metal sheet. The support plate 23 is formed of metal sheet, strip or plate. It is provided with the flange 42 and the patterns of protrusions 44 and holes 23. The film 28 is first positioned by applying relatively low air pressure. The film 28 is then subjected to air under a high pressure (e.g. 100 lbs./sq. inch), the air preferably being preheated. The film 28 is ruptured in the area of the holes 34 and flows through them to the other surface.

Title: Manufacture of compressor rotor blades and other structures resistant to foreign object damage
IPC: F01D5/14
Filed: 1972-10-20
Abstract: 1414146 Laminates GENERAL ELECTRIC CO 20 Oct 1972 48413/72 Heading B5N [Also in Divisions F1 B3 B7 and C7] A structure resistant to foreign object damage, e.g. a radome, compressor blade or strut, comprises a wire mesh overlying and bonded to a core structure by a bonding agent substantially filling the interstices of the mesh, the latter itself being overlaid by a metal cladding. In one arrangement, Fig. 5, a compressor rotor blade comprises a core 15 of elongated graphite fibres embedded in a resin matrix. A stainless steel wire mesh layer 20 is wrapped around the leading edge of the core 15 and bonded thereto by resin which fills the interstices of the mesh. The latter is overlaid by nickel cladding 22. Additional wire mesh layers 24 may be embedded in the core matrix. The blade is constructed by forming sheets 18, Fig. 1, of parallel graphite fibres embedded in a resin matrix as well as sheets 26 of stainless steel mesh 24 in a similar matrix. Sheets 26 may additionally include loosely woven cloths of glass fibre (30, Fig. 9, not shown). The sheets 18, 26 are then cut to shape and stacked together with the fibres of adjacent sheets 18 angled with respect to each other and the wires of mesh 24 inclined at 45 degrees to the sheet edges. The assembly is cured in a mould to form a laminated structure, the mesh layer 20 either being incorporated during moulding or applied thereafter. In the latter case mesh layer 20 is wrapped round the moulded blade, coated with a bonding agent such as epoxy resin filled with aluminium and then cured under heat and pressure. The nickel cladding 22 may alternatively be applied by electroplating in such a way that the nickel layer has a thickness of 0À025 inch at the leading edge tapering to about 0À005 inch at the trailing edge of the mesh. The resulting step at the latter region is filled by cured polyurethane 100 faired into the aerofoil shape. In a modification (Fig. 6, not shown) a recess is cut in the blade surface to receive the mesh and cladding layers 20, 22 so that no fairing material is required. In a further modification (Fig. 12, not shown) the subsurface mesh layer (20<SP>1</SP>) is formed into a point at the blade leading edge rather than being smoothly rounded. In other arrangements, boron, silicon carbide or alumina filaments may be substituted for the graphite, the matrix material may be aluminium and the wire mesh titanium. Dimensions of the wires fibres &c. are quoted.

Filed: 1973-10-18
Abstract: 1431723 Burning fluent fuel AQUA CHEM Inc 18 Oct 1973 [30 Oct 1972] 48651/73 Heading F4B Fluent fuel and insufficient air for complete combustion are injected at one end of combustion chamber 31, which is arranged to radiate heat to a surrounding space, and sufficient additional air to complete combustion is injected to surround the core of flame with colder air, over at least part of the length of the combustion chamber. A perforated wall 45 at the combustion chamber outlet ensures mixing of the core and sheath streams and complete combustion in the combustion space of a tubular boiler. The sheath air may be introduced through louvres so that it swirls about the flame core, and additional air may be introduced near the exit end of the combustion chamber. The gases may pass through a layer of refractory material 55, Fig. 3, to which air may be supplied, as they exit from the chamber, to improve the mixing of the flame core and sheath air. The arrangement reduces the production of nitrogen oxides.

Title: Inspect of Metal Billets for Defects.
IPC: G07C3/14
Filed: 1966-10-31
Abstract: 1,161,066. Electromagnetic flaw detectors; proximity detectors. REPUBLIC STEEL CORP. Oct.31, 1966 [Nov.1, 1965], No.48759/66. Heading G1N. The major surfaces of elongate, rectangular cross-section, metal billets are inspected for flaws by moving the billets longitudinally along a horizontal path with two major surfaces facing upwardly at 45 degrees to a vertical, detecting the arrival of each billet in succession at a testing station and lowering each of two test heads into a position adjacent a respective one of the two upper surfaces and reciprocating the test heads transversely to the path to scan the width of the upper surfaces of the moving billet, the test heads each comprising a pair of search coils spaced in the direction of travel of the billets so that the effective scanning frequency is doubled. In one arrangement, steel billets are conveyed by V-shaped rollers through one testing station (20) and then turned over and conveyed through a second testing station (22). Alternatively, additional test heads may be provided for inspecting the lower faces. The arrival of a billet at a testing station may be sensed by photo-cells which initiate the operation of a hydraulic system to lower the test heads. The first part of the lowering may be done rapidly until a roller 103 is urged against the billet whereupon subsequent lowering is more gradual. Each test head may be reciprocated by a pneumatic piston, the direction of movement being automatically reversed whenever one of two proximity detector coils 112, 113, Fig.11, senses that the assembly has reached the edge of the billet. As shown in Fig. 11, each search coil assembly has two search coil units, 110, 111, each of the type described in Specification 1,114, 999 arranged side by side in the direction of travel of the billets and also two paint spray jets (114, 115) are provided so that when a flaw is detected that one of the two jets which is trailing the search coil units is operated to mark the flaw. The test head assembly has inclined lower edges designed to flatten or ride over any slivers which may protrude from the surface of the billet. When the billet has passed, its absence is sensed by the photo-cells which initiate operation of the hydraulic system to raise the test heads. To facilitate calibration, a bar (205) having a known defect, can be raised by a pneumatic piston into the line of travel of the billets. Proximity detectors. The two proximity detector coils (PC1, PC2, Fig.14, not shown), which are resiliently mounted for limited movement with respect to the search coils, together with cable capacitance (CA1, CA2), are connected in the resonant circuits of respective Hartly oscillators so that these oscillate when their proximity coils are not adjacent a metal billet and cease to oscillate when they sense the metal. Relay (SOL-P) controls the direction of scanning according as proximity coil (PC1) or (PC2) has detected the edge of the billet and relay (MR) selects which of the paint spray jets is to be used in the event of a flaw being detected.
