Title: Peristaltic pump
Inventor: HOPFENSPERGER REINHOLD
IPC: F04B9/02
Filed: 1991-02-12
Abstract: Abstract Peristaltic Pump A peristaltic pump which is equipped with a flexible tube arranged along a circular path and in which a com-pression member is driven by an electric motor via a gearing is to be compact and easy to manufacture, so that it can be produced at such a low cost as to be also suitable for applications where it has so far been too expensive.            To accomplish this, parts of the pump are combined with parts of the gearing.            (Fig. 2) R. Hopfensperger - R. Tungl -A. Rockermeier 19-7-1

Abstract: En matière de soins à apporter aux arbustes d'ornementation durant la saison froide, il est plusieurs catégories qu'il faut protéger du vent, du froid, de la glace et particulièrement du chlorure de calcium que l'on retrouve souvent sur les arbuste à cause des travaux de déneigement. La méthode la plus usuelle de protection est l'utilisation de jute enroulée sur un bâti ou directement sur l'arbuste à protéger. Dans la présente invention il a été conçu un abri fabriqué à partir d'une membrane, à la manière d'un sac ouvert pour en façiliter l'installation, lequel sac une fois mis en pla çe est refermé par des attaches. Comme il est préférable que cette membrane soit enserrée sur l'arbuste, il a été prévu une gaine longitudinale, fabriquée à même la membrane, dans laquelle gaine est insérée une baguette d'enroulement que l'on peut enrouler en même temps que la gaine sur elles-même réduisant ainsi par cette opération le diamètre du sac, enserrant de ce fait le sac sur l'arbuste le tout étant ensuite retenu par une ou des attaches. Une gaine a aussi été prévue à l'ouverture du bas et contient une lanière d'étranglement. Une cheminée sert d'ouverture de respiration pour l'arbuste. Dans cette invention il a aussi été conçu un abri pour haies fabriqué de sections de membrane, à installer directement sur la haie et retenu en place par un système d'attache au sol lequel système est fabriqué de gaines, cables, cordes, ou élastiques et crochets de sol ainsi que de tiges anti-brise.

Abstract: A coin processing apparatus arranged to automatically execute a cancellation process for canceling acceptance of an inserted coin by detecting, on the basis of output levels of receiving coils in a plurality of sets of coin selecting coils disposed on a coin path, a fact that the inserted coin has been guided into a return path through the operation of a return lever. and also to judge the occurrence of coin jamming and coin counter-flow on the basis of the output levels of the receiving coils. The output level of the receiving coil in each of the plurality of sets of coin selecting coils is monitored so as to carry out the automatic cancellation process in case the output levels of the respective receiving coils concurrently exceed a predetermined threshold level and persist longer than a predetermined period of time. In case the output level of the receiving coil in at least one of the plurality of sets of coin selecting coils exceeds the, predetermined threshold level and persists longer than a second predetermined period of time, it is judged that the coin jamming has occurred.  Further, in case the output level of the receiving coil of the most downstream one of the plurality of sets of coin selecting coils exceeds the predetermined threshold level and the detection output occurs again after the lapse of a third predetermined period of time from the time point when the detection output has once ceased, then the coin judged as a true coin is treated as a false coin.

Title: Dispensing closure with unitary structure for retaining a pressure-actuated flexible valve
Inventor: ROHR ROBERT D
IPC: B65D47/20
Filed: 1992-01-07
Abstract: A dispensing closure is provided for an opening in an squeeze-type container and includes a body defining a dispensing passage for communicating between the container interior and the container exterior through a container opening. A flexible, self-sealing valve is provided with a peripheral flange, and the valve is mounted in the body for opening in response to increased container pressure. The body is of unitary construction and is molded from thermoplastic material with an upstanding peripheral wall that is subsequently deformed over the valve flange to retain the valve in the body. A preferred process for making the closure includes the steps of molding a unitary closure body with a seat for the valve flange surrounded by a peripheral wall, disposing the valve flange on the seat, and then deforming an upper portion of the wall into a generally annular configuration extending radially inwardly to overlie the seat and clamp the valve flange between the seat and the deformed portion of the wall.
Patent CA-2059377-A1 (CA)
Inventor: KUZMA PETER
IPC: A61M31/00
Filed: 1992-01-15
Abstract: A method of preparing a hydrophilic plastic cartridge by centrifugally casting polymerizable hydrophilic material in a rotating polymerization tube whose longitudinal axis is maintained parallel to the ground. The speed of rotation causes radial outward displacement of the polymerizable material which upon assuming a predetermined shape within the rotating tube is then polymerized to the predetermined solid configuration. The resulting plastic cartridge is characterized by smooth, unscored internal and external cylindrical surfaces. The cartridges are used as a rate-limiting membrane in drug delivery devices. Sterilized kits containing a disposable needle/syringe or trocar-like instrument and the drug delivery device are used for subcutaneous implantation of the device in an animal body.

Abstract: COMPRESSION GASKET FOR Y-CONNECTOR                ABSTRACT OF THE DISCLOSURE     A  Y-connector  with  a  compression  gasket  for compressing about a guidewire or catheter when inserted into an inner chamber of a Y-connector and compressed by a rim of a large knurled knob.   When the large knurled knob is twisted with an inward force, the rim engages the gasket with inward compression, causing the center  portion  of  the  gasket  to  expand  inwardly, thereby frictionally engaging against a guidewire or catheter.    The  inner  expansion  of  the  gasket  is substantially equal about the inner circumference of the  gasket,  thereby  providing  a  seal  between  the guidewire catheter and bodily fluids, such as blood.  A guidewire clamp is included at the end of a side arm extending from the Y-connector body.
