Title: Prepunched joining piece for metallic constructions - has punched bolt aperture pieces replaced until finally removed
IPC: A47B96/14
Filed: 1974-05-03
Abstract: The right angled joining pieces conventionally used have many holes to suit the diverse applications in which they are used. Normally a large number of the apertures are left unused, giving a weakening in the element and a dust trap. To eradicate this the bolt apertures (15) are punched out during fabrication and returned to their positions in the apertures. Having decided which apertures are necessary on assembly, the plugs (17) are knocked out by hammer blows.

Title: Automatic sugar cane harvester - has adjustable height suspension cutter, chopper air flow carrier, rotary ejector
Inventor: SOULAT RENE
IPC: A01D45/10
Filed: 1974-08-23
Abstract: The harvesting machine of 2282213 uses an air flow, at 90 deg. to the flow of chopped sugar cane and below the sugar cane flow, to discharge the chopped cane.

Title: Nickel and cobalt recovery from oxide based ores - with secondary extraction circuit to recover more cobalt
IPC: C22B23/00
Filed: 1975-02-13
Abstract: A process for the recovery of Ni and Co from an oxide-based ore consists of: (1) heating the ore in the presence of a reducing agent at temp. high enough to reduce the ore; (2) cooling the reduced ore in an atmos. free from O2 and contacting the ore with an aq. ammoniacal liquor of (NH4)2CO3 to form a sludge; (3) treating the sludge with O2 to dissolve the Ni and Co; (4) separating the sludge into a solid-free phase enriched with Ni and Co and a phase enriched with solid contg. residual Ni and Co; (5) wshing in counter-current the solid-enriched phase with an aq. ammoniacal liquor to produce a first ammoniacal washing liquor free from solids, enriched with residual Ni and Co and a second current enriched in solids, of washed ore free from Ni and Co, cooling the washing liquor and using it as aq. ammoniacal liquor for stage (2); (6) selectively combining the Ni and Co rich phase from (4) with S, using an agent contg. S ions to produce a mixed ppte. of NiS and CoS contg. the greatest part of the Co present from the start in the solid-free phase, leaving the greatest part of the Ni dissolved in the solid-free phase; (7) separating a part, free from solids, from the sludge produced in stage (6) in order to thicken it; (8) treating the thickened sludge with O2 to dissolve at least part of the Ni in the solid phase to increase the Ni content of the liq. phase; (9) separating the oxygenated sludge from (8) into a Ni-rich phase; solid-free, and a solid-rich phase of mixed sulphides and recycling the solid free-phase for mixing with the sludge produced in stage (6) before carrying out the separation in stage (7); (10) distilling the separated phase, Ni-rich and solid-free, from stage (7) to ppte. the Ni as NiCO3; (11) separating the sludge produced in stage (10) into a solid-free phase and a solid-rich phase contg. NiCO3; (12) calcining the phase contg. Ni NiCO3 to give NiO; and (13) treating the NiO with a reducing agent at sufficiently high temp. to produce Ni metal. Almost all the Ni and Co values in oxide ores can be recovered as high purty Ni metal (>=90%) and a mixed sulphide of Ni and Co. A secondary extraction circuit is employed to recover is approx. 30% of the Co normally lost in the ammoniacal leaching process.

Title: Energy converter using rise and fall of waves - has float operated rack and pinion and opposing sets of clutches
IPC: F16H31/00
Filed: 1975-05-16
Abstract: A structure (6) to obtain energy from the rise and fall of the waves has vertical legs (7) anchored to the sea bed (8) and supporting a platform (11) above wave level (28). A sub-structure (10a) on this forms a support (9a) for a vertically mounted rack (13). Below wave level, the rach has a spherical float (23) filled with plastics foam (26). As the swell of the waves moves the float up and down, the rack reciprocates and rotates a pinion (15). This, in turn, drives a motor through sets of pawl cluthes (17a, 17b). Each clutch transmits motion in a direction opposite to the other. A sphere (22) of denser material, mounted above the float, provides the inertia for the system.

Title: Twin measuring tape with centre finding device - has twin tape lengths on separate drums with sprung plunger between to indicate centre point
IPC: G01B3/10
Filed: 1975-05-26
Abstract: The twin measuring tape (10) consists of two measuring tapes (14, 16) mounted on separate drums with parallel axes and contained in a common housing (12). To find the central point of any object each measuring tape is pulled out and hooked over the edge of the object (26). The housing (12) is then moved in one or other direction until each tape indicates the same dimension at the point where it emerges from the housing (12). The head (22) of the centre punch (20) is then struck with a hammer and makes a mark on the surface of the object (26). The scales (15, 17) are so arranged that when used as a normal measuring tape it is equally convenient for either a left-hand or right-handed person.

Title: High energy high tension ignition system - restricts primary current to preset level to maintain constant power irrespective of voltage supply
IPC: F02P3/08
Filed: 1975-10-22
Abstract: The high energy high tension ignition system is intended for use with aircraft gas turbines where it is necessary to maintain a spark at constant power. A fixed frequency oscillator (1) sends pulses to the hysteresis comparator (2) which transmits them through the transistor (3) to the terminal (4) of the primary winding of the transformer. When the current in the primary windings reaches a pre-determined value the comparator (2) shuts off the pulses from the oscillator (1). Thus a constant current is supplied to the transformer (9) of the secondary circuit which generates a spark of constant power at the plug (8) by the discharge of the condenser (7).

Title: Insulated upper parts for transportation units - by separately moulding units forming bottom-side walls, and roof unit
IPC: B65D81/38
Filed: 1975-11-24
Abstract: Insulated or cooling upper parts for transportation units, e.g. motor-lorries, trailers, and railway wagons, are produced in two separate parts, i.e. a single, dimensionally-stable main unit forming the bottom, and side-walls, and a roof or cover unit. These units are each produced with two separate moulds having the required shape, size and other characteristics, and are then combined to form a dimension ally-stable upper part. Both units consists essentially of a hollow shell of a synthetic resin filled with fibre-glass, and are filled with a rigid polyurethane foam contg. fibre-glass. The units are joined together by an adhesive based on a synthetic resin contg. fibre-glass. Simpler, cheaper and more rational prodn. than conventional methods involving prodn. and assembly of separate panels. After assembly of the two units the resulting upper part is strong, light and dimensionally stable.

Title: Low inertia air brake - has alternating stationary and rotary discs released by air pressure against spring action
Inventor: GABILONDO FRANCISCO LEGORBURU
IPC: F16D55/40
Filed: 1976-07-01
Abstract: The low-inertia air brake has a set of alternating discs either turning with the shaft (2) or stationary. The discs (3, 1) are mounted between two bodies (4, 9) which are stationary and secured at a constant distance from each other by studs (5, 12). Springs (7, 13) fitting round the studs hold the discs hard against each other, thus locking the shaft completely. One of the bodies is fixed to the machine frame, and the other has formed in it an annular recess (14) in which a plate (8) is partly accommodated. When compressed-air is admitted to the chamber formed between plate and body, this moves the plate and the studs with it in opposition to the springs, and protrusions (15, 16) on the studs act in turn on the stationary discs, moving them clear of the rotary ones and releasing the shaft.
