Abstract: FLAIL HEAD                  ABSTRACT OF THE DISCLOSURE         A resilient extension for the flail elements of a flail-type material spreader is disclosed wherein the resilient extension is affixed to each respective flail head such that it sweepingly engages the interior surface of the material holding tank to substantially completely discharge all of the material from within the tank.  The resilient extension can be in the form of a flat planar member or of a cross-shaped configuration. This substantially complete discharge of material eradicates the starter flail "dead-head" problem by eliminating the mass of material which accumulates at the bottom of the tank.  A resilient extension for the starter flails is also disclosed.

Abstract: COMPUTER TOMOGRAPHY METHOD AND APPARATUS                        ABSTRACT       Apparatus is disclosed for providing electrical energy to orbital components of a computed tomography (CT) scanning unit.  The apparatus includes a number of high voltage slip rings immersed in an insulating dielectric material.  Each slip ring contacts a sta-tionary brush biased to contact the slip ring to insure maintenance of a low resistance path between a stationary source of high potential and a cathode and anode pair of an orbital X-ray tube.  A number of low voltage slip rings are further included to facilitate transmission of low voltages to other orbital components of the CT unit.  The apparatus is of a compact light-weight design and is mounted for rotation of certain components about an axis which intersects a patient's torso to provide CT scan-ning flexibility.

Abstract: Agent for textile livening with an antistatic effect and favourable dermatologic properties ABSTRACT            The invention pertains to the textile livening agent with the antistatic effect and fabourable dermatologic properties which contains softening, stabilizing, whitening, colouring, scenting and dermatologic components, anionactive, noniono-genic and cationactive tensides and other additives and 2-50 (preferably 4-25) wt.% of 3-(hydroxyalkylamino)-2--hydroxypropyl esters of fatty acids of the general formula RCOOCH2CH(OH)CH2N(R1R2), where R are the C16-C22 alkyle  or alkenyle, R1 is H, CH2CH2OH, CH2CH2CH2OH, CH3CHCH2OH, CH2CH(OH)CH3, CH3CH2CHCH2OH, CH3CHCH2CH2OH, CH2CH2CH2CH2OH, or CH3CHCH(OH)CH3, and R2 is the same substituent as R1 except for H. The agent serves for the repeated regeneration of antistatic and other properties of fabrics made of synthetic fibers and is applied to washed and rinsed fabrics by a short-termed soaking, moderate squeeze and drying.  The surface electric reactivity of the fabrics is effectively reduced even at the low humidity of environment already by a very small amount of the agent. The said agent is not toxic and its effect is not reduced even by certain amounts of anion-active detergents retained by fabric after incomplete rinsing.

Abstract: Abstract of the Disclosure A disposable instrument is adaptable for use in electrosurgical operations, such as, coagulation proce-dures used in blocking off fallopian tubes, and is charac-terized by having an improved electrode and switch assembly which permits interchangeable but permanent mounting of electrodes of a selected length and con-figuration within a handle grip.  The electrodes conven-tionally may be of a type having normally spaced-apart tips which through actuation of a plunger disposed for extension through the handle grip will cause the tips to be brought together to grasp or surround the tube or other tissue to be coagulated.  The interchangeable but positive connection of electrodes within the housing brings them into direct electrical connection with electrical contacts and specifically in such a way that the connection and mounting of the electrodes cannot be disturbed or broken.          An improved control circuit for the instrument assures normal interruption of the electrical circuit to the electrodes unless the electrode tips have been advanced to the tube-engaging position as described.  A switch in the sidewall of the housing is positioned with respect to the control circuit so as to permit positive movement in a direction establishing closure of the circuit into the electrodes only when the electrode tips are in the tube-engaging position.

Abstract: ABSTRACT         Starch glue is produced by gelatinizing an aqueous starch slurry at temperatures from about 95 to 160°C and applying high shearing forces.  Before the viscosity exceeds 15000cP a water-soluble oxidant producing nascent oxygen is added, and gelatinization takes place in a reaction system which in respect of the residence time spectrum exhibits close to ideal pipe reactor characteristics.  The contact time between the oxidant and the at least partially gelatinized starch at a temperature of at least 95°C is 1 to 5 minutes.  The resulting starch paste is mixed with raw starch.  The process permits the viscosity of the glue and/or the ratio of carrier starch to raw starch to be selectively varied while providing a glue with functional properties at least equivalent to those obtained with prior processes.
