Abstract: BAILER PUMPS FOR OIL WELLS   ABSTRACT OF THE DISCLOSURE   A bailer pump designed for securing to a well head comprising an elon-gated stan pipe projecting upward from the well head supporting a motor driv-ing a reel for cable through a drive train incorporating a magnetic brake, when the current to the motor is interrupted the magnetic brake is activated. A bailer is propelled into and out of the well in a repititious controlled manner.  The electrical control mechanisms operate in conjunction with a pivot arm mounted at the top of the stan pipe on an axle.  Pillow blocks re-tain the pivot arm in a tilting position.  Tension or lack of tension on the cable passing over the top pulley causes a reciprocal tilting of the pivot arm and the pulley.  The tilting pivot arm contacts a micro switch which through time delay and relays start, stop, and reverse the electric motor operating the cable reel.  The short delay in the well permits filling of the bailer and a long delay at the well head permits unloading of the bailer. The long delay is energized by the bailer striking a bailer stop contacting the top micro switch stopping the motor and activating the long delay.  The unloading function is accomplished mechanically by the bailer contacting the bailer stop pulling an actuating rod which through a trough linkage tilts the unloading trough under the bailer striking a dart at the bottom of the bailer emptying the contents of the bailer into an oil receiver.

Abstract: ABSTRACT OF THE DISCLOSURE         A coaster brake for a bicycle has a brake operating lever consisting of a yoke and integral arm coupled to the pedal crankshaft of the bicycle by a self-acting unidirectional friction clutch, formed by a coil spring embracing the crank-shaft.  In order to facilitate its insertion into the crank-shaft housing, the lever has no dimension greater than the internal diameter of the housing.  The spring has two portions, one on either side of the yoke, the wire forming the part of each portion nearer the yoke being of greater cross section than the part further from the yoke.  The lever moves a brake actuating rod or cable actuating a wheel brake which may be of several different types.

Abstract: VIBRATORY CONVEYOR IMPROVEMENT     ABSTRACT OF THE DISCLOSURE     This invention provides an improvement in a vibratory conveyor of the type including an elongate unitized container, which can be vibrated as a free mass at a selected frequency and stroke by drive means comprising a motor having weights, eccentrically mounted on its output shaft and that is inter-connected by yieldable means to elongate counterbalance means located opposite one long side of the  container with the long central axis thereof arranged generally parallel to that of the container.  Basically, the improvement of the present invention is that the counterbalance means is comprised of plural counterbalance sections which  are longitudinally arranged generally parallel to the long central axis of the container.  Preferably, the plural counter-balance sections are interconnected to one another by connector means that are generally rigid in a direction perpendicular to the stroke axis of the container but are generally resilient in a direction parallel to the stroke axis of the container.  The improvement of the present invention is particularly beneficial wherein the unitized container has a length of greater than thirty feet.

Abstract: Case 2956 DISPOSABLE URETHRAL CATHETER ASSEMBLY     Abstract of the Disclosure A disposable urethral catheter assembly includes a flexible bag in which are defined a number of chambers. In an upper cham-ber, a catheter is contained in a sterile environment. When the catheter is inserted into the urethra, the fluid flows into the bag and into a lower sample chamber, excess fluid being collected in the upper chamber. After catheter use, a cannula plug seals a first barrier between the upper and lower chamber and thus isolates the sample in the lower chamber. The upper chamber, its contents and the catheter are discarded, and the lower sample chamber and its contents are sent to a laboratory for analysis and culture.

Abstract: ABSTRACT OF THE DISCLOSURE:         This invention discloses an improved dental pulp capping and cavity lining composition which is successful in capping and preserving the vitality of moderately inflammed, as well as normal, healthy dental pulps and also serves as an acid resistant, protective cavity liner.  This composition is prepared by reacting suitable phenolic derivatives with formaldehyde or its polymer, under carefully controlled conditions, to form a low molecular weight polymer condensate, which is first purified and then compounded into a two-paste composition of optimized utility.  In use, one paste portion, containing the condensate, reacts with the other paste portion, containing calcium hydroxide, to yield after mixing a solid protective layer of set material, which facilitates healing of the pulp and formation of secondary dentin.

Abstract: ABSTRACT:         The invention relates to a shaving apparatus having a shear plate with hair entry apertures and a cut-ting unit which is rotatable relative to the shear plate. The cutting unit comprises a cutting member which is sub-stantially constituted by a central body which is pro-vided with cutters and with hair-pulling elements which are movable relative to the cutters.  The hair-pulling elements are provided with connecting arms whose ends are secured to the central body of the cutting member.  In such apparatus the problem occurs that hair cuttings are trapped between the connecting arms and the central body, thus seriously obstructing the cutting unit.  In order to eliminate this drawback a cover plate is employed, the ends of the connecting arms being situated between the central body of the cutting member and said cover plate.
