Abstract: FEEDING DEVICE FOR CAGED ANIMALS              Abstract of the Disclosure A gravity flow feeder for caged animals, especially fur bearing animals such as mink is disclosed wherein said feeder comprises an open ended container with front. side, rear and bottom panels.  The bottom panel slopes forward from the rear panel underneath the bottom edge of the front panel to form a ramp, wherein the bottom panel forms a trough beyond the front panel and the gap between the bottom of the trough and the bottom edge of the front panel provides an opening to permit flow of feed into the trough from the container.  A screen overlays the inside of the front panel, said screen being of slightly larger vertical dimensions than the front panel to at least partially cover the opening and of slightly smaller horizontal dimensions.  Attachment of the screen on the top edge of the front panel and the dimensions of the screen permit lateral and rearward movement of the screen.  This enables the animal by moving the screen to break up any clumps and insure a continuous supply of feed yet not provide an opening which will provide an escape route for the animal.

Abstract: ABSTRACT    A process is disclosed for the solvent refining of non-anthracitic coal at elevated temperatures and pressure in a hydrogen atmosphere using a hydrogen solvent which before being recycled in the solvent refining process is subjected to chemical treatment to extract substantially all nitrogenous and phenolic constituents from the solvent so as to improve the conversion of coal and the production of oil in the solvent refining process.  The solvent refining process can be either thermal or catalytic.  The extraction of nitrogenous compounds can be performed by acid contact such as hydrogen chloride or fluoride treatment, while phenolic extraction can be performed by caustic contact or contact with a mixture of silica and alumina.

Abstract: SOLITON SAMPLER                       Abstract The invention is an all-soliton sampler for accessing very high speed circuits.  A soliton is switched in two parallel branches, one including the device under test and the other including a programmable delay line implemented in soliton devices.  The outputs of these two branches are used as controls to a soliton comparator which, in turn, controls a Josephson detector gate.  This circuit permits a relatively slow rise time external trigger pulse to initiate an extremely narrow sampling pulse.            An object of the invention is to reduce the width of the sampling pulse (which is of order 5ps, set by the inductance and capacitance of the pulse generator) in order to decrease jitter, to obtain the fastest trigger pulse possible without generating appreciable crosstalk.            In the soliton sampler according to this invention, extremely narrow test-gate trigger signals and sampling pulses (of width A? 1 ps) are generated simultaneously by an external trigger with a relatively long rise time.  The addition of an on-chip programmable delay circuit allows high-resolution sampling to be done without appreciable jitter.  Problems with crosstalk are alleviated by allowing a long rise time on the external trigger.

Abstract: A B S T R A C T     A method and apparatus for removing debris involves an elongate string operable to pump the debris from a well into the string.  A pumping portion of the string includes a hollow piston with a hollow, splined piston rod fixed to the upper portion of the string, above the pumping portion, and keyed to the pumping portion to transmit rotary motion from the upper portion to the debris retaining portion below the pumping portion.  A hollow piston head includes a valve, advantageously a ball valve, to prevent downward fluid flow.  By reciprocating the upper portion, well debris is pumped into the debris retaining portion and solid debris is trapped therein by a one-way check valve.  The liquid debris, such as heavy water, continues upwardly through the string passing through the interior of the piston and into the upper portion.  The upper portion selectively receives either a ported sub, in which case the liquid is recirculated back into the well or an unported sub that prevents the return of the debris to the well.  An additional check valve may be located in the upper portion to retain the liquid in the upper portion and to relieve the stress on the ball valve.  The check valves, removably secured within removable subs, preferably are flap valves, including a torsion spring biased flap element with the torsion spring located out of the direct path of fluid movement to decrease valve fouling.

Abstract: ABSTRACT           In a large turbo-generator comprising a laminated stack which has on its outside axial grooves which are distributed over the entire circumference and which is there suspended in a housing by means of wedges extending in its longitudinal direction, the wedges are joined to a wedge carrier which extends parallel to them and is fixed at the housing.  The wedges are constructed of several parts and have a central center part which is detachably connected to the wedge carrier and which is essentially used for radial support.  As support in the circumferential direction, clamping devices, for example in the shape of double inclined wedges are provided which are arranged in pairs between the groove side walls and the wedge center part and which are located completely inside the groove and which can be actuated from the front of the completely laminated stator.  In this manner, mounting openings in the housing become superfluous and laminating is facilitated.
