Abstract: CONVECTIVE INERTIA FORCE FLOWMETER          Abstract of the Disclosure A mass flowmeter comprises a single conduit (1) with two extremities (2 and 3) affixed to a rigid frame (6), which conduit includes first and second sections (7 and 8) respectively extending towards one another from the two fixed extremities of the conduit in an over-hanging arrangement and connected to one another by a looped section (9) of the conduit. An electromagnetic vibrator (10) vibrates the first and second sections of the conduit relative to one another. A pair of the motion detectors (12 and 13) respectively measure the flexural vibrations of the first and second sections of the conduit. The mass flow rate of the fluid moving through the conduit is determined from the phase angle difference between the two flexural vibrations respectively measured by the two motion detectors.

Abstract: A JIG for WELDING MITERED JOINTS BETWEEN   the MEMBERS of MOLDED PLASTIC WINDOW and DOOR FRAMES     ABSTRACT of the DISCLOSURE     A jig for welding mitered joints between members of molded plastic window and door frames, comprising four mutually positionable clamp assemblies, one to each corner of the frame, each of which comprises a pair of horizontal rests serving to support the members of the frame, and respective upwardly-projecting fences disposed transversely and parallel to the horizontal exit path followed by the frames, that register with the external faces of the rails and the uprights of the frame; each clamp assembly further comprises a pair of plates, located above the corresponding pairs of rests, that serve-to hold the frame members fast against the rests as and when necessary. The fences disposed trans-versely to the exit path of the welded frame are embodied independently of the relative rests, and capable of movement between a first limit position, in which the rails are checked, and a second limit position in which the rails are freed and the fences themselves completely clear of the frame's transverse dimension.     fig 1

Granted: 1993-04-06
Abstract: ABSTRACT OF THE DISCLOSURE            An electromechanical vault cartridge receptacle has an opening for inserting a vault cartridge, the cartridge passing between  a pair  of laterally biased  rollers which  continuously  engage  asymmetrically  contoured sided surfaces of the cartridge.  A front surface edge of the cartridge bears upon and causes the backwards motion of a movable frame, the motion of which causes top and bottom surfaces of the cartridge to be securely engaged between an opposed pair of horizontally planar cartridge bearing members.  The backwards motion of the movable frame also results in roller supporting members to be locked when the cartridge  is fully  inserted, thereby preventing lateral movement of the rollers.  A cartridge  ejecting means  comprises  electromechanical means  adapted  for  engaging  a  back  surface  of  the movable frame to move the movable frame in a forwards direction, disengaging the cartridge engaging members and unlocking the roller supporting members, whereby the cartridge is pushed back out of the opening.

Title: Gate valve with lock ring
Inventor: CLARKSON CURTIS W
IPC: F16K3/02
Filed: 1988-12-15
Granted: 1992-11-10
Abstract: ABSTRACT OF THE DISCLOSURE      A packingless gate valve  is  disclosed  which  includes a housing having opposed similar housing halves with pipe nipples extending therefrom and with  resilient sleeve  units installed on respective  lock rings  mounted in  recessed portions of the housing halves.  The  sleeves act  to compressibly  engage each other in  the valve open condition and engage opposite sides of the gate in the valve closed condition.  Each sleeve unit has a radially  outwardly  extending  flange  on  the inner and outer axial ends with these flanges being located in indented regions between each lock ring  and the  respective housing  half.  An encircling thin stiffening ring of harder material is bonded to the axially  outer surface  of the  flange on  the inner end of each sleeve, each stiffening ring  being  shaped  with  a right angle bend  so as  to provide  both axially and radially facing surfaces for each sleeve body.  Each stiffening ring is engaged with the  respective lock  ring along  the entire length of the stiffening ring.  The particular configuration  and position of the sleeve  units with  the lock rings and stiffening rings has been found to  function  advantageously  in  maintaining proper operation of the gate  valve.   The gate valve construction of the present invention results in no leakage to the outside when the valve  is fully  open and no leakage to the outside or past the gate internally when the valve is fully closed.

Abstract: IN THE CANADIAN    PATENT AND TRADEMARK OFFICE     PATENT APPLICATION   entitled:      A METHOD OF FINISHING TWO OPPOSITE EDGES OF A                SINGLE WORKPIECE BY MACHINING, AND APPARATUS FOR IMPLEMENTING THE METHOD   in the name of:Charles Marcel SIMONETTO   assignee:      RENE TOUROLLE ET FILS, incorporated in France as an s.a.r.l.    ABSTRACT OF THE DISCLOSURE            A method of finishing two opposite edges (5, 6) of a single workpiece (1) by machining, the machining giving each edge a desired final shape by pressing the workpiece between a pair of tools (7, 8) having shapes (9, 10) complementary to the desired finished shapes for the two edges. According to the invention the complementary shapes (9, 10) of the tools (7, 8) are limited by causing them to correspond solely to the finishing zones (5a, 6a) of the two edges (5, 6), and during the finishing operation per se, the two tools are controlled to move simultaneously in translation (18-20, 19-21). The method is applicable to finishing holes through a high precision workpiece such as used in some jet engines.

Abstract: ABSTRACT OF THE DISCLOSURE A shopping cart display system and position sensing system includes a cart mounted display that is responsive to trigger signals provided by transmitters associated with a particular location.  When the display receives a unique trigger signal, it displays advertising media associated with that location.  In one embodiment, the display includes a sensor for determining whether the information is displayed in the presence of a consumer, and a memory for storing all trigger signals received during a given shopping trip.  The stored data is transmitted to a polling transceiver located at a point of sale register for later analysis and gives a log of all locations that the cart has visited.
