Title: Forming oil in water emulsions without emulsifier - using shock waves from superheated water generator
IPC: A23D7/00
Filed: 1976-02-25
Abstract: Oil-in-water compsns. are prepd. by using a generator of shock waves either without an emulsifier or in the presence of 1% surfactant such as a nonionic ethylene oxide condensate. The shock waves are provided by an appts. comprising a generator of superheated water operating continuously in a pulsating manner, the sudden decompression being regulated by a pressostat. Examples specified are in dairy foods made from milk and serum, and cheese coloured with carotene emulsion; also as a fermentation medium for producing amino acids and as a vaccine support; as in polymer emulsions and emulsion polymerisation and in exterior emulsion paints. As they do not require an emulsifier, which contributes some instability to the emulsions, they are more stable. They are stable at >60 degrees C in neutral or basic medium and in acid medium in the presence of a protective colloid.

Title: Armature slot wedging arrangement - has small tooth tip dimensions to reduce leakage fluxes across slot opening
IPC: H02K3/487
Filed: 1976-03-15
Abstract: A slot wedging arrangement for the armatures of d c machines to assist in reducing the commutating reactance, with the tooth tip dimensioned from the mechanical considerations only. The tooth tip neck width (bF) should not exceed one third of the tooth width (bH), and the tip height (hK) should be no more than 6 mm. With such a construction the leakage flux across the top of the slot is greatly reduced, and the saturation of the tip is of no great significance. The slot wedge (6) spans part of the teeth as well as the slot, and the design also permits the use of a channel shaped wedge which would allow the winding to project into the air gap.

A single operation and a single mould is sufficient, instead of several operations as previously.
Patent FR-2323070-A1 (FR)
IPC: F16G11/00
Filed: 1976-09-07
Abstract: The shock absorption device increases the deformation capability of cables and cable networks, especially in the case of high shock loads, such as stone impact. This results in the associated anchoring forces being reduced and cable breaks therefore being avoided, without derating. The cable (8) is constructed in the form of a loop in the anchoring region, and the loop (14) is fixed by means of two cable shackles (9, 10) and a clamping plate (13). The compression force which is applied via the screws (11) is set by using a torque wrench so that the static friction resistance is less than the cable breaking load. Since sliding and braking movements of virtually any desired length are possible, very high energies can thus be reliably absorbed, primarily by conversion into friction heat.

Title: Multipurpose injection moulding machine - with twin independent screws plasticising for ram packed mould tool
IPC: B29C45/13
Filed: 1977-02-25
Abstract: An injection moulding machine features two separate reciprocating screw plasticisation units which converge on to the axis of sprue passage leading from a mutual screw discharge chamber to the mould cavity. Aligned with the sprue passage is a piston which can advance to seal the passage and maintain the moulding consolidation or dwell pressure while the screw units are able to retract and masticate fresh material for the next shot. Suitable in principle for injection moulding thermoplastic, thermosetting or elastomeric materials. The minimum cycle time is not restricted by the period necessary for mastication of material. Hot residence times and consequent degradation can be minimised by matching the screw throughput capacity to individual alternate shots. The piston provides a better moving seal than a flighted screw.
