Title: Method and an apparatus for inspecting the edge of a lid
Inventor: SWART NICOLAAS C
IPC: G01N21/954
Filed: 1989-11-20
Abstract: ABSTRACT       The invention has for its purpose to provide a method and an apparatus for inspecting the bent edge of a disc-shaped object, e.g. the annular edge of a metal lid bounding a gutter for sealing compound.      In order to realize such an inspection with great reliability according to the invention the resolution is made as great as possible by means of the following steps:      (2) directing a light beam onto the edge zone of the object under an angle of incidents, such that the bent edge gives a shadow in said edge zone;  (3) previously determining the shape of the reflection picture also determined by said shadow of said illuminated edge zone in case of an object satisfying a predetermined standard;      (4) determining the reflection picture of the edge zone of an object to be inspected; and (5) comparing the results of steps (4) and (3) and generating a rejection signal in case of a detected deviation lying outside a previously chosen tolerance range.

Inventor: MCBRIEN GREGORY J
IPC: G01P15/13
Filed: 1990-02-27
Abstract: An accelerometer arrangement includes an acceleration sensor that includes two capacitor plates having respective parallel mutually facing major surfaces which bound a sensing gap therebetween. A plate-shaped electrically chargeable proof mass is resiliently mounted in the gap in parallelism with the major surfaces for displacement in response to the action of acceleration forces thereon out of a substantially central rest position toward one or the other of the major surfaces depending on the direction of the acceleration forces.  An electrical potential difference is established between the capacitor plates to generate respective electrostatic fields between the capacitor plates and the proof mass which cause a proof mass electrical potential variation having a magnitude and sense depending on the extent and direction of the displacement of the proof mass out of its rest position.  The variation is evaluated and an a pulse train that is proportionate to the variation is generated and supplied to the proof mass to establish thereat a voltage sufficient for electrostatic forces caused thereby between the proof mass and the capacitor plates to return the proof mass to the rest position thereof against the action of the acceleration forces on the proof mass.

Title: Regulated pressurized dispenser and method
Inventor: REYNER ELLIS M
IPC: B65D83/42
Filed: 1990-03-16
Abstract: A flexible closed plastic pouch disposable within a container holding a product for supplying dispensing pressure therein. A plurality of pocket members disposed at spaced positions within said pouch with their openings facing the interior of the pouch. Each pocket member having an extension of a predetermined length attached at its end to the interior of first of two facing wall members of the pouch. Each pocket member enclosing a predetermined quantity of first component of a two-component gas generation system and being releasably closed by one of a plurality of closure members, each of said closure members having an extension of a predetermined length attached at its end to the interior of the second of the two facing walls of the pouch. The pouch contains a second component of said two-component gas generation system and a starting means encapsulated within delay means or device to initially generate a predetermined quantity of pressurizing gas after a delay of a predetermined period of time. The pressurizing gas inflates and expands the pouch within the container under pressure. Due to the dispensing of the product, the pouch expands further and causes sequential separation of the pocket members from their closure members and serial opening of each pocket member to add predetermined quantities of aliquot of the first component to the second component and further generate additional quantities of pressurizing gas. The internal pressure within the container is maintained substantially within a range of predetermined maximum and minimum pressure levels until dispensing the product from the container is completed.
