Abstract: "FENCE PICKET ROLLER PAINTER"         ABSTRACT OF THE DISCLOSURE           Conventionally, fence pickets are painted by brush on the individual faces and side edges.  Alternatively, the front and rear faces may be painted by a roller coater but, due to space restrictions, the side edges must still be brush-painted by hand.  The present device consists of a bifurcated handle carrying for rotation a main transversely situated roller coater, with a pair of picket-side-edge-engaging rollers extending forwardly of the main roller and situated at right angles thereto, one adjacent each end thereof.  This enables one face and both side edges to be painted at the same time. The legs carrying the edge rollers and the main roller are angulated with respect to the handle so that when the one face and the two side edges have been painted, the roller assembly may be turned over so that the main roller may engage the opposite face of the picket with the edge rollers held clear of the side edges thereof.

Abstract: SECURITY STAND FOR MOTORCYCLE         ABSTRACT OF THE DISCLOSURE A security stand is provided which secures a motorcyle and each of its major, valuable components against theft. The stand does not utilize a padlock or chain either of which can be attacked by acid, quickly supercooled and embrittled by a cryogen, or easily cut with an oxyacetylene torch. The stand does utilize an internal locking means such as a dead bolt, which engages the ends of cross bar pipes necessarily containing cementitious material, which pipes are inserted in passages through a pair of angulated arms. The arms extend upwardly from a base, and, preferably both arms and base are also filled with cementitious material. The angulation of the arms is such that they do not provide a horizontal surface against which a hydraulic jacking means may be biased in cooperation with the base, or ground upon which the base is disposed. The cross bar pipes function as locking members when they are inserted through openings between the frame and engine of the motorcyle and locked in the arms. Plural pipes are preferably used, each of which may be locked with a separate locking means. The stand of this invention, as assembled for use, is simple, requiring an internal, concealed key actuated locking means and only three structural components, namely a base, angulated arms and elongated hollow locking members, and preferably each of the components is filled with cementitious material. The filling of cementitious material provides several functions: (a) it provides a reservoir ofheat to counter the effect of a cryogen poured on the locking member, (b) it decrepitates under the intense heat of a cutting torch, (c) it dulls a metal-cutting hacksaw blade, and (d) it provides weight to anchor the structural components of the stand.

Abstract: ABSTRACT OF THE DISCLOSURE:         Residual materials which become available in metallurgy and contain oxides and volatilizable nonferrous metals or compounds thereof are treated in a rotary kiln with solid carbonaceous reducing agents and are thus directly reduced in a high proportion to sponge iron whereas a substantial part of their nonferrous metal content is volatilized.  The solids discharged from the rotary kiln are sieved with a parting size of about 3 to 10 mm, depending on the feed grading of the residual materials and their disintegration characteristics, so that a major part of the unmagnetic material is included in the fine fraction.  The coarse fraction is subjected to electromagnetic separation.  The magnetic fraction is subjected to an electro-slag resistance process.  The unmagnetic fraction is incorporated in and bonded to the feed mixture for the rotary kiln by a tumbling or pelletizing operation.

Abstract: ABSTRACT OF THE DISCLOSURE          A winch system for raising and lowering sceneries or similar loads on a stage is disclosed.  The system comprises a series of support members adapted to be secured to the joists of a ceiling, an elongated winch drum made up of several sections interconnected by universal joints and supported in horizontal position by said support members, each winch drum section being provided over part of its length with a helical groove on which a cable for supporting the load is wound.  Each support member carries bearing wheels engaging the helical grooves for rotatably supporting the winch drum and for causing its axial displacement at each turn by a distance equal to the pitch of the cable wound or unwound from the winch drum, such that the load will not be laterally shifted when being raised or lowered.          The shaft of a reversible hydraulic motor is secured to an end of the winch drum, whereby the hydraulic motor moves with the winch drum in its axial movement.  The housing of the hydraulic motor is provided with a torque arm engaging a stationary guide extending parallel to the winch drum to prevent rotation of the motor housing.  The hydraulic motor is controlled by a three-position spool valve, the position of which is controlled by a reversible electric stepping motor.  Movement differential between the stepping motor and the winch drum produces progressive closing and opening of the valve which results in smooth acceleration and deceleration of the load during raising or lowering, and an accurate positioning of the load. A brake is preferably provided to stop the winch drum when the hydraulic motor is not supplied with fluid under pressure.

Abstract: CANDY ?     DIGITAL-TO-DIGITAL CODE CONVERTER            Abstract of the Disclosure A digital-to-digital converter is arranged to provide "decimated" output samples at rate fO, each of which represent a group of input samples received at a rate m times greater.  Each output is generated using overlapped triangularly weighted accumulation on an interval including 2m preceding input samples.  The samples near the beginning and end of each accumulation interval receive the smallest weight, and the samples at the middle of the interval receive the greatest weight.  The converter comprises first and second serially connected accumulators, the first accumulator accumulating m input samples without weighting and the second accumulator being used to weight the samples so that the first accumulator receives m times the weight of the last sample.  The output of the first accumulator is increased in scale by the factor "m" and the output of the second accumulator is subtracted therefrom in subtractor. The difference is delayed in store so that the next m samples may be accumulated.  The output of the second accumulator is then combined with the delayed subtractor output to yield the desired overlapped, triangularly weighted accumulation.                      FIG. 1

Abstract: PUMP APPARATUS                     ABSTRACT           A pump apparatus for transferring precise amounts of fluid from a container to a patient.  The pump apparatus has a defined volume pump chamber divided by a diaphragm into a first chamber volume and a second chamber volume.  The first chamber volume receives and exhausts pumped fluid in response to a decrease or increase in the volume of the first chamber volume in response to an increased pressure of a  pumping fluid in the second chamber volume.  The diaphragm and the pump chamber provide accurate per cycle pumping volumes.  The pumping fluid pressure is varied by periodically electrically heating a ribbon filament in a heating chamber inter-connected to the second chamber volume of the pump chamber thereby increasing the temperature and hence the pressure and/or volume of the pumping fluid.  The pumped fluid enters the first chamber volume through a one-way valve as the pumped fluid portion volume expands and is exhausted through a second one-way valve as the volume of the first chamber volume contracts.  Control circuitry is provided to allow variations in the pulse repetition rate and pulse width to control the pumping rate.  A feedback control loop may also be provided by sensing, for example, the fluid flow rate, pressure, temperature or other dependent variable and generating an error signal therefrom to control the pulse repetition rate or pulse width.
