Title: Injection-moulding of thick-walled, large-volume mouldings - by effecting successive pressure impulses during a post-pressure phase, on the compressible moulding cpd. in the mould
Inventor: SCHRAMM KLAUS DIPL ING
IPC: B29C45/57
Filed: 1976-04-02
Abstract: Injection-moulding comprises exerting periodically successive pressure impulses, after the injection step, onto the compressible, pref. thermoplastic, moulding cpd. in the mould, during a post-pressure phase. This pressure impulse is exerted upon the plastics melt (residual melt) in injection direction and transmitted, in dependence on frequency and rate of pressure increase, the through the sprue system into the mould whilst imparting a motion to the moulding cpd. This also results in a pressure impulse in the mould which decreases rapidly in the injection unit and causes moulding cpd. to flow back into the injection unit so that a reciprocating flow of moulding cpd. in the injection unit, the sprue system and the mould occurs, which prevents "freezing of the sprue system. Large, thick, mouldings can be injection-moulded without recourse to special flow-improving adjuvants. Fouling of the sprue system is prevented.

Title: Mass balanced water filled tank - contains empty vessel held down by weight, which disturbs and restores balance without effort upon lifting weight
Inventor: BEIKERT MICHAEL
IPC: F03B17/04
Filed: 1977-01-14
Abstract: The arrangement is for reducing the power required for lifting or pumping operations. A column pivotably supports a horizontal beam which carries a weight at one side and a water-filled tank at the other side at equal distances from the pivot point. An empty container is submerged in the water whose buoyancy is balanced by a weight to which it is connected by a rigid rod. The weight rests of a beam at a greater distance from the pivot than the tank support. In this position the assembly is in equilibrium. The weight can be lifted without much effort due to the buoyancy of the container. This disturbs the equilibrium and the container rises until the beam again supports the lifted weight.

Title: Fan for vacuum cleaner - has asymmetrical inlet opening to enable handling long threads without becoming blocked
Inventor: SANNECK HUGO DR ING
IPC: F04D29/42
Filed: 1977-08-03
Abstract: A fan housing (2) contains an impeller (4) which has centrifugal blades (5). An inlet channel (8) in the casing leads to a suction inlet (6) in the eye of the impeller. The channel comes from the cleansing pickup (9) of the vacuum cleaner. The inlet (6) into the impeller is pear shaped with a lobe (7) projecting asymmetrically on one side of the shaft centreline (3). This projection is in the delivery direction of the blades. This arrangement of the inlet prevents long threads picked up by the cleaner from taking up a symmetrical position on the dia. of the impeller from which the air flow cannot dislodge them. It therefore enables the cleaner to remove long threads and prevents its becoming blocked by them.
