Filed: 1980-08-12
Abstract: A machine for the profile grinding of woodshaping cutters 44 has a grinding wheel 10, a rotatable cutter support 34 and a cutter rest 48. The cutter blank 44 or cutter to be ground or reground is clamped to a face the support and then the support is turned until the projecting part of the cutter engages with the rest close to the periphery of the grinding wheel. The top relief angle ground by the machine is determined by the geometry of the cutter support and the rest; but the support has a plurality of faces 36, 38, 40, 42 of different perpendicular distance from the axis of rotation of the support. Hence the relief angle ground is variable according to which face of the support is brought to the operative position. The grinding wheel can be tilted to ground side relief on the cutter. <IMAGE>

Title: Milking device
IPC: A01J5/04
Filed: 1981-06-04
Abstract: A milker has a lower base 3 with a concave wall to and a lower exit 29 under vacuum that can be closed by a float 13 with valve 39 until the milk level pivots and/or raises the float to open the exit. An enclosure body 5 is fitted on the base and includes a main vacuum inlet 41 and a milk inlet nipples 25 positioned and angled to direct a substantial portion of milk inflow downwardly below the upper surface of the float. An enclosure cap 7 is releasably fitted on the top of the enclosure body and mounts an air valve, pulsation nipples and a further vacuum inlet. A central stem 17 from the bottom extends up through a central passageway in the float and also through the cap to afford a fulcrum or support for an arm 50 that pivots or slides to close the main vacuum inlet 41 when the air valve is opened. The float can pivot and rise to a limited extent when milking or when the milker is inverted for washing.

Title: Cable manufacture
Inventor: TAYLOR KENNETH
IPC: G02B6/44
Filed: 1981-06-23
Abstract: A method of providing a cladding layer on a stranded cable element including extruding an oversize metallic tube (8) directly over a stranded layer (7) of a cable by means of a continuous extrusion process such as a friction extrusion machine (26). The tube (8) is allowed to cool before being subsequently drawn down and swaged into intimate contact with the stranded layer (7) by means of suitable dies and/or rolls (27). When the cable core incorporates optical fibres (3), as in an optical fibre submarine cable, this cladding method avoids the high temperatures and pressures associated with friction extrusion techniques adversely affecting the optical fibres.   <IMAGE>

IPC: B23K11/00
Filed: 1981-07-02
Abstract: An edge detector is provided in a strip flash welding machine and comprises detectors (L and T) movable transversely of the strip flow path in the gap between the leading and trailing pairs of clamps (11 and 12). Having thus located the two edges of each of the old and new strips (20 and 22) the transverse position of the new strip (22) is adjusted by means of a cylinder (31) to align the centre lines of the strip ends. As particularly described, the detectors (L and T) are mounted on a shearing mechanism and edge detection takes place on withdrawal of the shearing mechanism. Said edge detection is also used to select from rows of weld clamping cylinders only those required to suit the widths of strips being clamped. An electro-hydraulic control system is described. <IMAGE>

Title: Method and apparatus for the manufacture of hollow elements from concrete
IPC: B28B7/08
Filed: 1981-12-23
Abstract: The invention provides a method of making hollow elements from concrete, comprising a first concrete slab (33) and a second concrete slab (36) with spacer elements (35) between them. The slabs are formed on casting surfaces (1, 2) located next to each other or one above the other, the first slab being provided with spacer elements (35) and, after being sufficiently set, being reversed above the second slab.

Title: Apparatus for cutting a plane- walled recess
Inventor: RILEY PHILIP JOHN
IPC: B27F5/06
Filed: 1982-01-08
Abstract: Two endless travelling cutting bands are mounted side-by-side to define in effect a blade which has four moving cutting edges and which, when sunk into an appropriate workpiece, will remove material from the area bounded by those edges to mill out from the workpiece a plane- walled recess, for example a rectangular hole which could then be elongated into a slot in a single extended sideways movement of the blade. The two runs of each band overlie the runs of the other band, and the bands are driven in respectively opposite directions and pass round a common axis at the blade tip and also at the blade root. The blade can be swung about the drive-input axis and fixed in the desired position relative to the drive-input means.
Patent GB-2091141-A (GB)
Title: Manufacture of axle bracket halves
IPC: B21K1/12
Filed: 1982-01-15
Abstract: The invention relates to a method for the manufacture of axle bracket halves. According to the invention, an axle bracket half is produced by extrusion moulding of an initial body, in which through changes in the cross- section of the shank region b the moment of resistance of the axle half can be increased with a saving of material. In the method of the invention, first a shank region b and a depression region c are formed from the ingot through hot-extrusion. The depression region c is then expanded and extruded into a rectangular shape and the shank region b formed into a square cross-section. In a final extrusion step the depression region c takes its finished form with local wall thickening. Openings for the drive- and cover side of the axle half can be punched out subsequently. <IMAGE>

Title: Production of double-base propergol propellant blocks
Inventor: BOUSQUET RENE
IPC: C06B25/34
Filed: 1982-10-14
Abstract: The propellant blocks are produced from a base powder comprising nitrocellulose (of nitrogen content 11.5 to 13% by weight), a nitramine (octogen and/or hexogen) and a combustion catalyst system. The base powder is gelatinised in a mould at an elevated temperature by means of a nitric ester (e.g. nitro-glycerine) as in French Specification 2165093. The improvement is that the catalyst system comprises at least one oxide of lead (e.g. PbO), Cu2O and/or CuO, acetylene- or benzene-black and, optionally, potassium cryolite. This enables a block to be obtained with high nitramine content (35 to 60% by weight), the resulting block having enhanced rate of combustion while still retaining uniformity of combustion.
