Patent CA-2109385-A1 (CA)
Inventor: FOSTER RAYMOND K
IPC: F16K15/18
Filed: 1993-10-27
Abstract: Abstract of the Disclosure A primary valve orifice (26) divides a check valve cavity into first and second portions (4, 6).  A valve member (34) closes the orifice (26) in response to higher pressure in the first portion (4) and is unseated to open orifice (26)  in response to higher pressure in the second portion (6).   An axial passageway (44) extends through the valve member (34). A control rod (50) extends into the cavity (4, 6) and through the passageway (44).  The rod (50) carries a secondary valve plug (52) that is biased by a spring (60) to close one end of the passageway (44), and a pull block (78) that engages the opposite end of the valve member (34).  A stem (40) extends from the valve plug portion (36) of the valve member (34) through the orifice (26) and is telescopically received in a sleeve (62).   The control rod (50) is pulled to cause the secondary valve plug (52) to unseat and the pull block (78) to engage the sleeve (62).   This opens the passageway (44) to equalize pressure on the two ends of the valve member (34). Further movement of the control rod (50) moves the valve member (34) and sleeve (62) as a unit to open the orifice (26).  The sleeve (62) may be omitted, with the pull block (78) directly engaging the valve member (34).

Title: Serpentine Structure for a Turnstile
Inventor: KOSIKOWSKI DAVID M
IPC: E06B11/08
Filed: 1993-12-08
Abstract: A turnstile gate with a serpentine configuration instead of conventional protruding arms.  Both the stationary and revolving gates are formed of a continuous configuration of pipe which loops back and forth with substantial straight sections oriented horizontally.  For the movable gate to pass through the stationary gate, the loops of the stationary gate must be offset from those of the revolving gate by one-half a cycle, and the loops of at least one of the gates must vary in their heights so that they can be located both outside and inside of the loops of the opposing gate.  The advantages of the configuration are safety, ease of manufacture and greater strength, with a unique aesthetic appearance.

Title: Method for Writing Data to an Electrophoretic Display Panel
Inventor: DISANTO FRANK J
IPC: G02F1/167
Filed: 1991-09-17
Abstract: A method for writing data to an EPID display (10) includes loading data (36, 38) for a line of pixels onto the grid lines (20) of the EPID. Insteadof writing that single line fully by enabling the associated cathode row (18) with a logical "1" voltage for the time necessary to cause complete pigment particle migration, the associated cathode line and at least the next adjacent cathode line are enabled (40) for a shorter duration than is required for fully writing the lines. The grid is then loaded with data corresponding to the next line of pixels and the set of cathode lines enabled is shifted by one line (44).such that at least one cathode line previously enabled is enabled for a subsequent time whereby particle migration for writing is made more complete where the grid data is constant from one row of pixels to the next.

Abstract: PROCESS AND PLANT FOR THE PRODUCTION OF UREA   IN REACTION SPACES WITH DIFFERENT YIELDS                           ABSTRACT            In a process of  producing urea  in which ammonia and carbon dioxide are reacted in a first reaction space (E-1,  R-1) the unreacted carbamate present in the reaction mixture   is   subjected  to   a  thermal  decomposition treatment,  so as to obtain ammonia and carbon dioxide which are sent to a second reaction space (R-2) in which they react with a solution of recycled carbamate coming from an urea recovery section (3). Advantageously,  the regulation of the temperature and of the ammonia/carbon dioxide molar ratio in the second reaction space (R-2) is carried out by respectively regulating the temperature of the recycled carbamate solution and the temperature of the  thermal  decomposition  treatment  of  the  residual carbamate leaving the first reaction space (E-1, R-1).

Patent CA-2128082-A1 (CA)
Inventor: REEDER ROBERT D
IPC: H04M3/42
Filed: 1994-07-14
Abstract: A switching system (10) is modified to provide, in addition to conventional connections (110 + 111) between ports (100, 103), eavesdropping connections that couple only one-half of a conventional bidirectional connectionbetween a pair of ports to a third port (102). If the pair of ports serves an adjunct processor such as a voice-mail system (11) and a user voice terminal (13), a voice- or speech-recognition unit (12) serving the adjunct processor may be connected to the third terminal to receive thereat only the transmissions (112) of the user voiceterminal without the unwanted transmissions of the adjunct processor. If the transmissions of the user voice terminal are polluted with echoes of the adjunctprocessor transmissions, then each half of the conventional connection between the adjunct processor and the user voice terminal may be connected to a different one of two ports (102, 103) serving the voice- or speech-recognition unit, whereby the recognition unit is able to receive the polluted transmissions (112) of the userterminal separately from the transmissions (113) of the adjunct processor and use the latter to perform echo cancelling functions on the former so as to obtain only the transmissions of the user voice terminal without the unwanted transmissions of the adjunct processor.
