Abstract: ABSTRACT OF THE DISCLOSURE          The present invention relates to improved apparatus for forming a tubular plastic sleeve immediately prior to its application to a rigid base article, such as a glass or plastic bottle.  A rectangular blank of plastic material is wrapped around a cylindrical mandrel and seamed lengthwise thereon to form the tubular sleeve.  The mandrel has a plurality of spline-shaped grooves in its curved peripheral surface and a stripper ring mounted to closely surround such peripheral surface to be slidable thereon.  The ring has a plurality of internal lugs which slidably fit within the spline-shaped grooves.  The mandrel has a lineal array of vacuum ports for retaining the leading and trailing edges of the plastic blank on the mandrel for its wrapping thereon, and an axial resilient strip mounted in the curved peripheral surface of the mandrel for operation of a movable, axially-extending sealing bar thereagainst.  A wedge-shaped expansion member is also mounted in a wedge-shaped channel or groove in the mandrel peripheral surface between a pair of spline-shaped grooves.  The expansion member is adapted to be moved vertically with respect to the mandrel for contraction of the mandrel diameter to release the newly-formed sleeve for its removal therefrom.  The sleeve is then applied to a glass or plastic bottle for heat shrinking thereon in a thermoconstrictive operation.  The apparatus is especially adapted to forming a wide range of thicknesses of a variety of heat-shrinkable thermoplas-tic materials into suitable tubular sleeves for telescopic mount-ing on such containers in a rapid, efficient manner.

Abstract: ABSTRACT OF THE DISCLOSURE           A mechanism for transporting printing plates includes a swiveling lifting cylinder carrying on its extendable and retractable piston rod a dish-shaped plate which is equipped with suction elements.  The printing plates are stacked in inclined positions in a plate holder.          When so stacked, the coated, photoconductive sides of the printing plates face downwards and are protected from damage by sheets.  For transporting a printing plate to an exposure table, the dish-shaped plate of the lifting cylinder is lowered onto the uncoated side of the printing plate which lies on top of the stack in the plate holder until the suction elements rest on the printing plate.  Then, reduced pressure is applied to the suction elements so that they grip the printing plate by suction, and the piston rod is partially retracted into the lifting cylinder.  Then the lifting cylinder swivels to a vertical position and places the now horizontally lying printing plate on a conveyor track where it is engaged by rollers and is further trans-ported, after the reduced pressure of the suction elements has been released.

Abstract: ELECTRICAL RECEPTACLE OF MOLDED BODY CONSTRUCTION                       ABSTRACT    A general purpose receptacle having selective single and split circuit electrical modes is adapted for mounting in a standard floor or wall mounting box.  The receptacle is formed of a molded, one-piece receptacle body and a molded, one-piece receptacle front.          Selection of single or split circuit operating modes is achievable by a break-off tab which normally electrically connects two sets of female contacts as a single circuit but which can be broken off so that the female contact sets are electrically separated.  The receptacle is wired by placing the unstripped ends of insulated conductors at insulation severing terminals connected to the female contacts and forcing the conductors into the terminals.  To accomplish this, a pair of suitably shaped side covers are hinged to the front part of the receptacle top to provide the requisite insulation-displacement forces.  With the side covers secured in position, no terminals are exposed which might otherwise make electrical contact with metallic parts of the mounting box.  Mount-ing, insulation severing and circuit mode selection can all be performed by using a screwdriver.

Abstract: ABSTRACT A digital speed measurement circuit for an engine includes a magnetic pick-up positioned adjacent an engine-driven gear having a substantial number of teeth so that the pick-up produces a number of speed pulses per revolution of the gear. These pulses are shaped into square waves by a signal conditioning circuit and connected through a synchronizing circuit which responds to the trailing edge of each square wave to produce a triggering pulse, with each triggering pulse supplied to a tooth counter. A high speed clock is connected to a second counter which is reset with each triggering pulse. A sampling pulse is produced in an associated control system which is not coordinated with the speed pulse but which is longer in duration than any of the speed pulses and which controls the flow of tooth counts to the tooth counter. Memory circuits retain the high speed counts measuring the intervals between a triggering pulse and the beginning of a sampling pulse and between the end of the sampling pulse and the triggering pulse immediately preceding. Another counter counts the high speed counts occurring during the sampling pulse period. These factors are combined as described to provide a high speed count of a new measuring interval exactly related to the speed pulse count and which is combined with the speed pulse count to provide a digital signal which accurately represents a desired function of engine rotational speed.

Abstract: R.J. Williamson - D.N. Batchelder 14-6 (Rev.) VORTEX FLOWMETER     ABSTRACT OF THE DISCLOSURE    A bluff body is placed in a fluid pipe with one flat face facing the oncoming fluid.  Vortices are then generated and shed alternately from opposite edges of the body.  This body is of a scalene triangle cross section, and in one version a hole extends transversely therethrough.  A longitudinal hole intersects the first hole at right angles thereto.  The vortices cause oscillations in the transverse hole.  A light beam is provided in the longitudinal hole.  The light beam is modulated as it crosses the path of the transverse hole.  Hence by measuring the frequency at which the beam is modulated and by suitable calibration, one gets a good and reliable indication of fluid flow rate.  In a second version the transverse hole is formed into a blind hole at the foot of which is an etalon (a Fabry-Perot interferometer).  The effect of the fluid oscillations due to vortex generation influences the etalon so that its output is a measure of the fluid flow rate.

Abstract: ABSTRACT OF THE DISCLOSURE           A shelf and display structure in which horizontal or sloping members (16, 18, 20) are mounted on a vertical element (12) by locking structures (14.1, 14.2, 14.3).  Each locking structure includes a pair of arms (28) which are generally triangular in side elevation.  Each arm has three grooves in the outer face thereof.  The inner face of each arm is generally flat and merges at one end with a rolling surface.  When two arms are placed in co-operating relationship with their rolling surfaces in contact, the arms diverge from one another.  In this condition they can be inserted into an elongate mouth of the element (12) and the outer ends of the arms can then be pressed towards one another, the arms rolling on their rolling surfaces until the flat rear faces are juxtaposed. During such rolling motion the element 12 is deformed by the arms so that frictional forces are created which resist movement of the locking structures along the element (12). A horizontal member (16) or sloping members (18, 20) can be mounted on the arms by co-operation between these members and either the horizontal or the sloping grooves.  Knobs, hooks or other devices can be mounted on the members (16, 18, 20) to enable articles to be displayed or , where the member is horizontal, it can support shelves.
