Title: Prodn. of highly absorbent fibrous web - by forming gel of solvent and chemically modified cellulose, removing unbound solvent, spraying to separate fibre and forming web
Inventor: RYDELL THEODORE B
IPC: A61L15/28
Filed: 1978-05-31
Abstract: A highly absorbent fibrous web is made by (a) mixing chemically-treated cellulosic fibres with a solvent to form a fibre gel mixture; (b) removing unbound solvent from the gel to the extent that the amt. remaining is with 5 g/g fibre of the fibre (c) satn. pt. spraying the mixture in an air stream onto a moving carrier and drying the web on the carrier. The spraying acts to dry the mixture sufficiently to separate it into discrete fibres. The softness weight etc. of the web can be controlled by altering the various spraying parameters, e.g. air stream velocity, and directing the rate of movement of the carrier. The chemically-treated cellulose must be (i) cellulose that has been chemically substituted, etherified or esterified (and opt. crosslinked) or (ii) cellulose that has been grafted without dissolving the fibres to the extent that they are not identifiable.

Title: Electric motor stator assembly - has feather key interlock in groove to transfer angular momentum from laminations to externally anchored housing
Inventor: KAGISCHKE WOLFGANG
IPC: H02K5/04
Filed: 1978-12-21
Abstract: The key bar is firmly welded to longitudinal stiffening ribs (7, 8) which are further stabilized by a bottom plate (12) and transversal stiffening plates (13). This arrangement when being put together is first turned to the precise dia. dimension (9) so that feather key bar (6) may be laid on it between the converging tips of the said longitudinal ribs ready for welding. Then the stator package is inserted so that the groove fits over the key bar. Finally the key bar is secured to the stator housing by welding. This working process has the advantage that the problem of tolerances in the prior machining of grooves does not arise; partic. if there are more than one groove or key slot on the stator package - often required for transferring a large turning momentum - the precise positioning of the key bars relative to the key slots is automatically achieved.
Patent DE-2856896-A1 (DE)
Title: Measuring shrinkage of holes to store radioactive waste - esp. holes in subterranean salt domes which are heated while capacitor monitors redn. in hole dia.
Inventor: MUELLER ROLAND DIPL ING
IPC: E21B47/06
Filed: 1978-12-30
Abstract: The highly radioactive waste (HAW) gives off heat, so that after a long storage time the holes in subterranean salt formations employed for storing the HAW undergo shrinkage. The shrinkage is measured by applying a constant amt. of heat to the region of the hole for several weeks, and using a capacitor to monitor the change in hole dia. The capacitor uses two ring electrodes, one of which is fed with a sinusoidal voltage of known frequency; and the capacitor provides a signal voltage (Us) representing the dia. (2r) of the hole. The pref. appts. employes a probe contg. a heater for the hole and also the capacitor, which consists of an outer ring electrode with overlapping ends so the ring can shrink in dia. to correspond with the shrinkage of the hole. Holes are drilled in subterranean salt deposits for the long-time storage of HAW; and the holes are lined with tubes. The pressure caused by shrinkage of the salt must not cause the tube to shrink in dia. The HAW is contained in steel drums placed in the tubes.

Title: Force transducer with frequency output - controls electromagnets by switching logic to produce automatic null balance
Inventor: BORBERG HARTMUT ING GRAD
IPC: G01L1/14
Filed: 1979-03-24
Abstract: The force acts upon a body which is constrained to lie between two electromagnets. The forces produced by the electromagnets on the body are controlled to balance the external force and maintain the body in the centre. A rotational arrangement can also be used. The control circuit modulates a switching signal so that the number of pulses to the magnets yields a measure of the force. This modulation is affected by the changes in the inductance of the two coils as the body moves and requires no other sensing to maintain the required null position.
