Title: Soil improvement agent and fertiliser prod. - by treating composted domestic refuse with sulphite waste liquor
Inventor: MUELLER GEB BRUENNER ILSE
IPC: C05F15/00
Filed: 1977-01-15
Abstract: In the prodn. of soil-improvement agents and/or fertilisers, composted domestic refuse, opt. in admixture with clarification sludge, is treated with 5-20% of its weight (dry basis) of sulphite waste liquor. Addition of sulphite waste liquor overcomes the water-repellent properties of composted domestic refuse and gives a product which is water-absorbent and has good water-binding capacity. This avoids the soil drying effects and erosion problems normally associated with the use of composted domestic refuse as a fertiliser. In an example, composted domestic refuse (90 wt. pts.) was mixed with dried sulphite waste liquor (9 wt. pts.). In field trials, the mixts. obtd. gave considerable improvemtn in plant growth without giving rise to crusting of the soil.

Title: Vibration exciter esp. for compressor shakers - has idle running at constant speed still allowing reloading
Inventor: FECHTER LEONHARD DIPL ING
IPC: B06B1/16
Filed: 1977-09-20
Abstract: The imbalanced mass used to produce the vibrations comprises one or more imbalanced bodies (15, 16). The weights of the bodies are measured and positioned on the axis of rotation according to wt. so that in at least one adjustable position the centrifugal force which results from the effective imbalanced mass formed from all the imbalanced bodies is equal or almost equal to nil. When the imbalanced bodies are in one position to cancel out the imbalanced forces the exciter no longer produces any vibrations and it rotates like a substantially balanced device so that under these conditions the exciter can run between compacting processes without impeding the supply of new material and the removal of the compacted slab.

Title: Injection moulding machine with fixed and movable crossheads - has detachable tie rods widening scope, facilitating mould changes
Inventor: QUERE HENDRIK K
IPC: B29C45/67
Filed: 1978-05-02
Abstract: A moulding machine, esp. an injection moulder, comprises a mould section secured to a fixed crosshead, a mould section secured to a movable crosshead, a driving mechanism for displacing the movable crosshead relatively to the fixed crosshead, tie rods connecting the two crossheads when the two mould sections are (partly) in contact, and hydraulically operating details which can completely close the mould sections and hold them closed against the high internal injection pressure. Each cross-head is provided on the side turned away from the mould section, with a rigid frame. Between >=1 crosshead and its rigid frame, a number of hydraulic pressure cylinders are arranged. These form the hydraulically operated details mentioned, and the tie rods are secured detachably to the perimeters of the two rigid frames so as to link them together, with the help of the double-acting pressure cylinders, when the moulds approach each other. The tie rods are provided at both ends with two sets of profiles which engage with similar profiles along the edges of the rigid frames. The edges of the rigid frames may thus be castellated. The detachable tie rods facilitate the assembling and dismantling of the movable mould section. Fixed tie rods determine the axial length of the moulding and hence of one or both mould sections.
