Patent CA-2009039-A1 (CA)
Title: Rupture disk failure indicating apparatus
Inventor: FRITTS DONALD K
IPC: F16K37/00
Filed: 1990-01-31
Abstract: Abstract of the Disclosure The present invention provides apparatus for visually indicating the failure of a rupture disk comprised of an elongated hollow body member, a piston disposed in the body member which is moved therein by pressurized fluid pressure exerted thereon,  and an elongated indicator pin which is pushed by the piston through an opening in the body when pressurized fluid causes the piston to be moved therein. The body member includes a pressurized fluid exhaust port which is opened by the movement of the piston.  Pressurized fluid exhausted through the exhaust port can be vented to prevent abnormal rupture disk operation or it can be uti-lized to activate an alarm.

Title: Injection molding cast manifold
Inventor: GELLERT JOBST U
IPC: B29C45/26
Filed: 1990-05-17
Abstract: ABSTRACT OF THE DISCLOSURE         A cast manifold for distributing pressurized melt in an injection molding system. The melt is received at a central inlet on the rear surface of the manifold to an inlet portion of a melt passage.  Four identical outlet portions of the melt passage branch radially outward from the inlet portion to equally radially spaced outlets on the forward surface of the manifold.  Each outlet portion extends around a first smoothly curved bend from the inlet portion, along a radial portion, and then around a second smoothly curved bend to the outlet.  By casting on a removable ceramic mold, the bends in the melt passage are very smoothly curved and do not all have to extend in a common plane.  Furthermore, the radial portions angle a substantial distance rearwardly as they extend outwardly which allows the thickness of the manifold to be reduced.

Title: Photoimaging process using water removable coatings
Inventor: WELLER EDWARD L JR
IPC: G03F7/04
Filed: 1990-06-21
Abstract: PHOTOIMAGING PROCESS USING WATER REMOVABLE COATINGS     ABSTRACT        Photographic images may be produced on a backing such  as  paper  and  polyester  sheets,  from  photographic negatives  which encompass  line  rendering,  design comps, copy,   complex   color   separation   or   the   like  with water-based varnishes and pigments,  the resulting images closely resembling,  if not exactly, the same image in its commercially  printed  form.   Thus  all  aspects  of  color proofs produced by this invention provide greatly improved predictability as to the appearance of the final printed job,  with  a  further  improvement  of  cost  savings  over conventional techniques of preparing color proofs.  Also, said proofing method can be used to provide a "transfer" so that one may transfer the colored image or images to a more suitable or required backing.

Filed: 1990-07-12
Abstract: Abstract of the Disclosure:       In a radio communication apparatus in which an audible tone is generated (21-22) in response to reception (15-17, 19) of either a primary or a secondary call signal and stopped by a reset switch (23), the audible tone is stopped (172, 18) when the secondary call signal is received.  When the primary call signal is received, the audible tone is not stopped unless the reset switch is continuously closed during a predetermined time interval.  Alternatively, the audible tone is stopped when the reset switch is twice closed although the audible tone is produced again after the audible tone is stopped when the reset switch is once closed.  As a further alternative, the audible tone is stopped in response to repeated closure of the reset switch without being again produced when the reset switch is once closed.

Title: Process for drawing off a milk sample
Inventor: KOECHLI HEINRICH
IPC: G01N33/04
Filed: 1990-09-18
Abstract: In the equipment for drawing off milk samples from a milk conveyor pipe (1), in order to remove any milk remaining from the previous supplier and adhering within the suction pipe (5) and the injection syringe (6), before taking a sample from the current supplier the suction pipe (5) and the injection syringe (6) are filled with milk and after being completely filled they are emptied again by pumping the milk back into the conveyor pipe (1).  The process of filling to fullness is monitored by a control means (9) which operates a hose pump (7) such that only the exact quantity of milk required to fill the suction pipe (5) and the injection syringe (6) is conveyed.  Only after this filling and emptying procedure is the injection syringe (6) inserted into a sampling bottle (8) disposed on a dish (15) which can be raised.  A holding down device (16, 17, 18) guarantees perfect withdrawal of the injection syringe (6) from the sampling bottle (8) when the dish (15) is lowered at the end of the sampling.  The equipment is characterized by the simple process permitting the left-over milk to be removed from the suction pipe and the injection syringe, thus preventing carry-overs.

Title: Optical fault finder
Inventor: BUERLI RICHARD
IPC: G01M11/00
Filed: 1991-03-11
Abstract: Abstract of the Disclosure An optical fault finder employing a novel processing technique to achieve greater sensitivity to loss detection and location of faults.  The technique includes the use of a matched filter which sequentially operates on a set of datapoints in the trace signal.  The resulting matched filter function generates peaks at those locations corresponding to discrete losses in the trace signal.  In order to optimize response of the matched filter with respect to reflective faults, a clipping filter is applied to the trace signal, prior to the matched filter, to remove reflective signals.  Means are also provided for determining the value of the loss, and for optimizing the pulse width of the test signal launched into the fiber under test.
