Title: A composite hydraulic ram for injection mould locking system - providing a repeatable two-stage closing action
Inventor: LAMPL ALFRED DIPL ING
IPC: B29C37/00
Filed: 1975-10-15
Abstract: A complex hydraulic ram for two stage closure of mechanical linkages for shuttin an injection mould tool used to pressure form material injected into temporarily oversize cavity, in which the advance of a hydraulic piston driving a rod coupled to the mould traverse toggles can be stopped by an annular ram having a rear face driving the main piston. Adjustment of the relative position of two coaxial sleeves forming the barrel for the pistons fixes the position at which the annular ram stops the main ram. i.e. for the closure level at which the cavity is filled. Subsequent relief of the back pressure on the rear face allows both rams to advance further to complete the closure action and consolidate the moulding when the combined rams meet a further stop. Esp. for moulding to close dimensional tolerances, i.e. for optical profiles or where a high surface finish is required. More repeatable adjustment and position of the mould traverse stop positions than use of timed operation of hydraulic circuit valves controlling a ram not governed by mechanical stops.

Title: Wire coiling mechanism with rotating drive shaft - has radial arms on rotor plate winding wire round cylinder to fall away in loops
Inventor: CHALIHA INDRAJIT
IPC: B65H54/82
Filed: 1975-11-05
Abstract: The wire (42) is led over a guide (12), and vertically downwards through the hollow drive shaft (18) which is rotated by the drive shaft (44) through a chain and sprocket, or a gear arrangement (46). When the wire (42) has passed through the hollow drive shaft (18), it is led over the pulleys (40) mounted to the lead-on radial arm (36) of the rotor plate, from where it is wrapped around the block (14) a few times to ensure a continuous hawser effect to enable the wire to be pulled. After the turns of wire on the block (14) cover the total surface area of the block, the wire under its own weight begins to fall away from the block (14) and the free end engages the radial arm (38). This rotor arm ensures that the looped wire leaving the block (14) will not engage or snag the rotor plate or radial arm (36). This looped wire may then be led away helically to a hopper or conveyor system for further processing.

Title: Surface measurement apparatus for machined materials - uses adjustable reference grating optical correlator
Inventor: WILLHELM JOERG DIPL ING
IPC: G01B11/30
Filed: 1975-12-06
Abstract: The surface measurement and test apparatus for machining processes consists of a reference grating (2) with a preselected raster constant which is placed above the surface of the material under investigation (1'). Light reflected from the surface of the material through the reference grating is concentrated by a condenser lens (3) onto two photoelectric detectors (4)(5). The electrical output from the detectors is proportional to the amount of coincidence between the reference raster and the surface structure of the material. A light correlation system may also be employed whereby an image of the surface structure is projected onto the raster. The raster pattern may be made adjustable to accommodate a range of surface finishes. Fresnel plates may be used for this purpose.

Title: Effluent purification using electrolytic cell - with prior treatment with ultra-sonic energy and removal of gross solids as a foam (OE150376)
Inventor: LAIZNER HANS DIPL ING DR
IPC: C02F1/465
Filed: 1975-12-08
Abstract: In the purification of effluents contg. fine or very fine suspended solids or dissolved, emulsified or suspended organic and/or inorganic impurities, if necessary pretreated to remove gross impurities by electrolysis in a horizontal electric field, optionally in the presence of foam formers, the sludge so formed being withdrawn and the effluent being supplied in co-current to the rising gas bubbles, specifically the effluent to be purified is treated acoustically (a) prior to entering the electrolytic cell by ultrasonic energy at a frequency of >=20 and pref. 30 kHz and (b) pref. also as it passes through the zone in the cell containing the electrodes, but at lower sound energy density than in (a). The prior treatment with ulta sonic energy ensures that agglomerates etc., are disintegrated and dispersed so that the suspended solids can be more readily carried upwards by the gas bubbles while the sound energy provided in the electrode zone ensures that solids deposited on the electrodes are constantly removed, thus permitting the electrodes to be brought closer tougher and reducing the size of the cell and the electrical power required.

Title: Caustic lime prodn. by calcining low-grade materials - in special furnace utilising low-grade oil as fuel
Inventor: BUITENDYK ANDRE
IPC: C04B2/10
Filed: 1976-04-21
Abstract: Furnace comprises a burning chamber, a reaction chamber and a separator. A special burner suitable for burning a low-grade oil, such as a spent machine oil, is fitted in the wall of the burning chamber. The starting material is carried through the chamber in the stream of the burning gases and is calcined in a vortex in the reaction chamber. Movable baffles are adjusted in such a manner that the gas flow maintains the vortex in the middle of the reaction chamber. The relatively light CaO particles are carried over to the separator and are discharged through the outlet. The heavy components of the starting material are discharged from the reaction chamber through opening. Lime that can be readily slaked (without caking) can be produced from low-grade carbonates because of the efficient separation of the heavy impurities. Cheap fuel can be utilised.
