Abstract: ABSTRACT OF THE DISCLOSURE           A dynamically balanced V-grooved sheet metal pulley made from a flat sheet metal disc by roller spinning and splitting tools.  The disc is provided with a central hole for mounting the disc on rotating die means between first headstock and tailstock die form assemblies of a spinning machine.  The spinning tool presses the disc against an end of a headstock die form and moves generally radially outwardly pressing a portion of the die against the end of the die to provide a circular hub wall.  The spinning tool then moves in a series of passes along the headstock die form thereby rolling, forming and ironing the rotating outer metal por-tions of the disc against the die and forming an axially extending cylindrical side wall terminating in a radially outwardly extend-ing annular flange of a cup-shaped stage blank. The flange is then trimmed to a predetermined length and to form a peripheral axially extending edge on the flange. The cup-shaped blank then is transferred to and clamped between second headstock and tail-stock die form assemblies. The clamped cup-shaped blank is rotated and splitting roll means splits the peripheral edge of the annular flange by exerting radial pressure thereon to form a rough Y-shaped groove in the flange.  Finishing roll means the move radially into the rough V-shaped groove and forms a finished V-shaped pulley groove.  Alternately, the spinning tool may thin the metal in the cylindrical side wall during the forming of the cup-shaped stage blank, whereby the finished pulley has a thicker reinforced circular end wall for receiving a hub than the thinned cylindrical side wall.

Abstract: ABSTRACT OF THE DISCLOSURE              Fastening means for a hinged door consists of a locking cam shaped like an elongated hooked finger, swingable about a vertical axis to and from overengaged relation with a keeper pin to secure and release the door.  The cam is tapered to reduced vertical thickness toward its free end and is keystone-shaped in cross section.  The keeper pin is contained in a keeper housing into and out of which the cam moves.  The keeper housing has wall portions with which the cam is engageable if the door is sagged or misaligned, so that due to its tapered form the  cam urges the door toward realignment during closing. Due to the cross-sectional shape of the cam, the area of contact between the cam and such wall portions of the housing is limited (theoretically to a point) during movement of the cam to and from the locked position.

Abstract: ABSTRACT OF THE DISCLOSURE        There is disclosed a rear-view-mirror arrangement for detachably mounting to the window of a vehicle. The arrangement comprises an arm member including an intermediate main extent and, at the opposed ends of the main extent, first and further end extents. The central longitudinal axes of the main extent and the further end extent make an angle of less than 90° with each other. A device for holding a mirror is mounted on the first end extent of the arm member. A securing device is mounted on the further end extent of the arm member. The securing device includes an attachment member of substantially U-shape in transverse section having limbs spaced apart by a maximum distance equal to or slightly greater than the thickness of the window. The securing device further includes a sleeve carried by what, in use, is the outer limb of the attachment member, in which sleeve is rotatably received in the further end extent of the arm member. The arrange-ment is such that, in use, the further end extent of the arm member is located at the edge of, or externally of the area of vision of the driver of the vehicle to the mirror.

Abstract: ABSTRACT OF THE DISCLOSURE          A monitoring system is disclosed for measuring and classifying the decelerating capabilities of a machine, such as a punch press.  The monitoring system includes a timing circuit for measuring the elapsed time from the initiation of brake application to the stopping of the press.  Means are provided to distinguish between a regular top-stop in a single stroke press cycle from an emergency stop and to shut down the press if the stopping time is excessive for the type of stop being executed.  The monitoring means is provided with a self-checking system which performs dynamic self-checking at the initiation of clutching .  In each self-checking cycle a fault simulating signal is propagated through two independent paths or through a path which has been previously checked.  The fault simulating signal will cause the press to be shut down unless it causes a control signal to change from an enabling state to a disabling state and back to the enabling state in less time than that required for the actuation of the relay means for shutting down the press.

Abstract: SEMICONDUCTOR SWITCHING CIRCUIT            ABSTRACT OF THE DISCLOSURE         A semiconductor switching circuit comprising a semiconductor element having an equivalent four-layer structure of a PNPN conductivity type formed by con-necting the collector and the base of an NPN transistor respectively with the base and the collector of a PNP transistor and having a function of self-holding alternately two states, i.e. its on state and off state, a gate-turnoff thyristor, and a gate control circuit which provides to the gate of the gate-turnoff thyristor a current for turning on the gate-turnoff thyristor when the semiconductor element is conductive, and a current for turning off the gate-turnoff thyristor when the semiconductor element is cut off, whereby electrical switching is achieved by turning on and off the gate-turnoff thyristor in accordance with the state of the semiconductor element.  The semiconductor switching circuit is useful as a cutoff switch used in a telephone exchange equipment since it consumes very small power because the semiconductor element is cut off when the gate-turnoff thyristor is conduc-tive and since it has a large current capacity when the gate-turnoff thyristor is conductive.

Abstract: Abstract of the Disclosure A bag constructed of biodegradable material in the form of high dry-strength and no wet-strength paper combined with water-soluble plastic material laminated to a portion of the exterior of the bag.  The bag is of a size to receive a bedpan as specifically disclosed but it may also be of a size to receive an emesis pan or the like when inserted therein with the bag completely enclosing the pan to maintain the aseptic characteristics of a sterile pan by completely preventing any possible contact between the pan and the patient or excrete from a patient thereby eliminating the necessity of cleaning and sterilizing bedpans  emesis pans and the like which results in substantial saving of time, labor and cost  of caring for a patient. The bag, after use, is easily separated from the pan by means of a separable seam and flushed into the sewer system through a conventional commode with the water soluble plastic being dissolved by the flushing water and the paper becoming disintegrated so that the plumbing system will not become clogged.  The water soluble plastic has the characteristic of maintaining its strength at temperatures above approximately 60 degrees F. so that excrete at body temperature will not dissolve the plastic material.  However, the plastic becomes dissolved by water at temperatures below approximately 60 degrees F. so that when it is placed in a commode hopper or the like the flushing water which is at a temperature below approximately 60 degrees F. will dissolve the plastic material.  The bag will also climate the use of bedpan liners, prevent staining of plastic pans, prevent odor from penetrating into plastic pans, extend the life of conventional pans, eliminate cold bedpans and assure the patient that the bedpans, emesis pan and the like is, in fact, sterile.
