Title: Squeezable fluid container
Inventor: BILLMAN FRED L
IPC: B65D35/08
Filed: 1989-11-15
Granted: 1994-05-17
Abstract: Abstract An improvement in certain types of fluid containers is disclosed.  The improvement is particularly directed to a certain type of squeezable fluid container that is made of a flexible plastic material.  Such a fluid container defines a longitudinal axis and a cavity for containing a dispensable fluid.  The fluid container has flexible side walls, a sealed bottom, a pair of spaced-apart sealed deformable side-edge margins, and a sealed deformable upper-edge margin which is unitary with an upper-edge portion of each of the side-edge margins and which defines a fluid-discharge passageway of generally serpentine configuration that communicates with the fluid cavity.  The improvement comprises an indent, defined by at least one of the side-edge margins, for dividing the fluid cavity into two fluid chambers along the longitudinal axle.  The two chambers are in fluid communication with each other.  One of the two fluid chambers is located adjacent to, and is in fluid communication with, the fluid passageway. The transverse cross-sectional area of the one fluid chamber, which is in fluid communication with the fluid passageway, is greater than the transverse cross-sectional area of the fluid cavity in the vicinity of the indent.  The indent is so located relative to the upper-edge margin such that fluid communication between the fluid passageway and the one fluid chamber adjacent thereto is maintained when application of a predetermined fluid-discharging squeezing pressure upon the fluid container sidewalls causes deformation of the container side-edge margin in the vicinity of the indent.

Patent CA-2038993-C (CA)
Inventor: SAKAI TSUTOMU
IPC: C09J7/38
Filed: 1991-03-25
Granted: 1995-04-18
Abstract: The adhesive composition of the invention exhibits an adequately controlled adhesive bonding strength when paper sheets coated therewith are bonded together to be adaptable to subsequent separation of the bonded sheets of paper by peeling.  The essential ingredients of the adhesive compo-sition include:  (a) a rubber latex;  (b) a silica gel powder having a specified average particle diameter; and (c) a starch, preferably, having a specified particle diameter, e.g. wheat starch, each in a specified weight proportion. In addition to the good balance between the reliability of the adhesive bonding and subsequent peelability, the paper sheet coated with the adhesive composition is prevented from a decrease in the adhesiveness even when the surface is contaminated with a silicone oil and from the troubles due to blocking when adhesive-coated sheets are stacked one on the other with the adhesive-coated surfaces in direct contact with each other.

Title: Diametral runout reducer
Inventor: PECK DAVID E
IPC: F16C3/02
Filed: 1991-05-09
Granted: 1996-11-26
Abstract: An apparatus which may be used to drivingly engage a rotating shaft, reduce the effect of the diametral runout thereof and drive a rotary sensor including a sleeve placed coaxially about the rotating shaft and drivingly engaging the shaft by means of mating splines. Any diametral runout present in the rotating shaft is directly imparted to the driven end of the sleeve. A spherical annular protrusion extends radially outwardly from the sleeve and slidingly engages bore having a central axis coincident with the preferred axis of rotation. In this manner, the center of the spherical annular protrusion, and consequently that portion of the sleeve, is maintained coincident with the preferred axis of rotation. The opposing end of the sleeve drivingly engages the rotary sensor with mating splines. If diametral runout is present in the rotating shaft, the sleeve will gimble about the center point of the spherical annular protrusion. A reduction in runout will be realized which is in proportion to the ratio of the distance from the center point of the spherical protrusion to the driven end versus the distance from the center point to the driving end.

Title: Valve
Inventor: WAIJ PETRUS BERNARDUS ADRIANUS
IPC: B65B/
Filed: 1992-03-02
Granted: 2002-11-12
Abstract: Valve comprising a valve stem (6) and a valve disc (7). The peripheral edge (8) of the valve disc in the closed position comes to-rest in a sealing manner against the valve seat (10) of the corresponding valve housing. Between this seal-ing peripheral edge and the valve stem the valve disc is partially made of elastical-ly yielding material. The position of the valve stem guide is such that it is possible to move the valve further in the direction of closure after the peripheral edge rests against the valve seat. This means that a vacuum can be created with the aid of the valve according to the invention. Such a vacuum can be used in filling devices for drinks. The nozzle in this case is made of a relatively flexible material which closes when vacuum is created. In this way after-dripping of drinks in, for exam-ple, juice packs can be avoided.
