Title: Device for lashing objects to a loading surface
Inventor: SCHWARZE ERHARD
IPC: B65D19/44
Filed: 1982-09-15
Abstract: The invention relates to a device for lashing objects to a loading surface, for example to a pallet. The main element forms a film provided with straps which at the same time protects and secures the object to be lashed. In a preferred embodiment, the straps are constructed as slotted straps so that different gripping lengths are obtained by hooking in fittings. Preferably, a component which consists of two hook halves and is secured against unintentional release by mutual abutment is used as a fitting. In a departure from this, a fitting consisting of two wedge foot halves can be used if the pallet or the loading surface is provided with wedge grooves. This fitting also provides automatic securing against unintentional release.
Patent DE-3238238-A1 (DE)
Title: Industrial chimney
Inventor: SCHWANKE HARTMUT
IPC: E04H12/28
Filed: 1982-10-15
Abstract: Double-walled industrial chimneys with intermediate insulation have hitherto been fabricated in such a way that a mineral-wool mat is applied to the inner pipe. This type of insulation has the disadvantage that it slips after erection of the chimney and cold bridges are then formed at the places without insulating material, the consequence of which is a fall below the dew point and hence corrosion of the inner pipe. The invention relates to a method of providing the intermediate space between inner and outer pipe with a homogeneous insulation which is incapable of slipping. The heat loss of the chimney is many times less than with chimneys of conventional design. This results in increased efficiency of upstream heat-recovery plants and hence lower energy costs for the entire plants.

Title: Transport and shielding flask for moulds with highly radioactive waste
Inventor: ENGELMANN HANS-JUERGEN
IPC: G21F5/14
Filed: 1982-12-30
Abstract: A transport and shielding flask for moulds with highly radioactive waste, consisting of a thick-walled, cylindrical shielding body having a receptor channel for receiving the mould, which completely penetrates said body, is arranged centrally and is vertical in the flask, and charging and discharging closures which seal the channel above and below. The new flask is to be capable of use in a storage system, and to satisfy specific requirements. In this case, particular value is placed on guaranteeing optimum shielding under all operating conditions, and on external influences being as far as possible incapable of impairing the closure system with regard to its shielding effect and its functionality. This is achieved when the two charging and discharging closures in the upper and lower end part of the flask are identical in each case, each closure consists of a rolling slide which can be rotated about a horizontal axis that is perpendicular to the longitudinal axis of the flask, and said rolling bodies are formed from disc-shaped solids of rotation whose two end faces have in the middle stub shafts and axles which are mounted in the axle in the upper and lower end part. In this arrangement, the solids of rotation are wider or thicker seen in longitudinal section than the diameter of the channel, and are penetrated perpendicular to their circumference by bore holes whose diameter approximately corresponds to the diameter of the channel. The stub shafts have axles for ... Original abstract incomplete.

Title: Injection moulding machine for the simultaneous pre-injection and final injection of a plurality of injection mouldings
Inventor: NEUMEISTER ERNST
IPC: B29C45/16
Filed: 1983-10-25
Abstract: The invention relates to an injection moulding machine in which two mould halves with mould cavities (6, 7; 11) are provided, the two mould halves being adjustable with respect to one another for the pre-injection and final injection in one movement step and one mould half having mould cavities for pre-injection and mould cavities for final injection. It is desirable here if the injection moulding machine has a lower volume on account of a suitable arrangement of the mould cavities or if a pre-determined number of mould cavities requires less overall space. This is achieved by disposing the mould cavities (6, 7; 11) in the two mould halves in continuous rows extending in the direction of the movement steps, adapting the length of the movement step to the distance between adjacent mould cavities, and, with reciprocating movement steps, alternating in each case one mould cavity (6) for pre-injection with one mould cavity (7) for final injection in the rows of one mould half. The change from pre-injection to final injection and back is made with these small movement steps, thus reducing the space requirement of the machine. <IMAGE>
