Title: Disposable test packs for steam or gas sterilizers
Inventor: HART MARVIN L
IPC: A61L2/26
Filed: 1990-09-11
Abstract: ABSTRACT OF THE DISCLOSURE             Disposable test packs and methods for determining the efficacy of a sterilization cycle in steam or gas sterilizers are provided.  The test packs include a container having top and bottom walls with a porous packing material, such as compressed divellicated polypropylene blown microfiber microweb, disposed within the container.  The packing material challenges the penetration of the sterilant by providing a restricted pathway which acts to impede the flow of the sterilant through the test pack.  A removable lid seals the upper end of the container, while a hole in the bottom wall of the container allows for the upward ingress of steam into the packing material within the container.  The test pack includes either a biological indicator or a chemical indicator or both for detecting sterilant penetration and thus the efficacy of the sterilization cycle.

Title: Flexible high energy magnetic blend compositions based on rare earth magnetic particles in highly saturated nitrile rubber and methods of processing the same
Inventor: KUAN TIONG H
IPC: C08K3/08
Filed: 1990-09-18
Abstract: ABSTRACT A flexible magnetic blend composition is pro-vided which is comprised of high energy rare earth mag-netic particles in a flexible high temperature resistant and oil resistant polymer binder.   The binder system preferably comprises a highly saturated nitrile rubber (HSN) or a polymer alloy of the same in which a HSN is the major polymer and also contains additives which are compatible  with  processing,  subsequent  electron  beam curing, and final product performance.  The binder system is highly  loaded,  usually from about  50 to about 70 volume percent, with the high energy rare earth magnetic particles, which can produce bonded magnets with a maxi-mum energy product of at least 2.5 megagauss-oersteds, a remenance, Br of at least 3400 gauss, a coercive force, Hc, of at least 2900 oersteds and an intrinsic coercivi-ty, Hci, of at least 5000 oersteds.  The process for pro-duction of this system involves the binder system and rare earth magnetic particles being mixed and then formed into a final geometry before being cured by high voltage electron beam radiation.  The electron beam curing in the solid state fixes dimensional stability, magnetic proper-ties,  and oil,  solvent and chemical resistance of the part even when exposed to subsequent hostile temperature environments of 100°C or higher.  Further, the HSN binder system  reduces  oxidation  of  the  rare  earth  magnetic particles from subsequent hot air aging when compared to conventional nitrile elastomer binder systems.   Any off geometry parts or trim produced in the process prior to radiation  curing  can  be  recycled  through  processing several times without fear of premature cure.

Title: Group control for lifts with double cages with immediate allocation of target calls
Inventor: SCHRODER JORIS T
IPC: B66B1/14
Filed: 1991-05-21
Abstract: In this group control, upper as well as also lower cages of the double cages can be used at a main stopping place for journeys to even-numbered and odd-numbered storeys. For this purpose, a respective call store (20, 21), in which the calls entered at the main stopping place and identifying the target storeys are stored, is associated with the lower and the upper cage. A switching circuit (32) at its input side stands in connection with the call stores (20, 21) in such a manner that the double cage concerned is scheduled in dependence on a allocated call as stopping at storey pairs numbered even-odd or odd-even. At the output side, the switching circuit (32) is connected with a switching equipment (31), which has the effect that either the double cages stopping at storey pairs numbered even-odd or the double cages stopping at storey pairs numbered odd-even are excluded from the allocation process in the case of a further call still to be allocated in order to maximise the possibilities for co-incident stops without losing flexibility.

Title: Device for administering medication to animals
Inventor: CAMERON DONALD
IPC: A61D7/00
Filed: 1991-10-18
Abstract: ABSTRACT OF THE DISCLOSURE An improvement in a device for administering medication to animals.  The improvement resides in a combination of a needle and a sliding valve member.  The needle has an exterior surface, a first end and a second end.   The first end is secured to a medication chamber.  The second end has a point such that the needle is adapted to penetrate an animal. Substantially radial openings are positioned on the exterior surface adjacent the second end. A central fluid flow passage extends from the first end of the needle to the radial opening whereby medication from the medication chamber communicates with the exterior surface of the needle.  The sliding valve member is positioned on the exterior surface of the needle. The valve member is movable between a closed position and an open position.  In the closed position the valve member covers the radial openings thereby maintaining medication in the medication chamber.  In the open position the valve member is spaced from the radial openings thereby permitting medication to  flow from the medication chamber through the  radial openings into the animal.  The valve member is moved from the closed position to the open position by the hide of the animal upon penetration.

Title: Free space local area network system
Inventor: OLMSTEAD CHARLES
IPC: H04L45/50
Filed: 1991-11-06
Abstract: ABSTRACT OF THE DISCLOSURE In a local area network the conventional "hard wire" connection between a data communication device and a network segment is replaced with a pair of transmitter/receiver units which communicate optically through free space.  The optical connections can be configured to conform to a variety of conventional protocols including carrier sense multiple access/collision detect and token passing ring protocols.  The transmitter/receiver units can communicate with each other by means of coded control signals which are not passed along the network.  In this manner, the optical link is managed directly by the transmitter/receiver units and many of the problems, such as collision detection and failed link removal, which have plagued the prior art are avoided without involving the network.

Title: Process and machine for the production of a tight complex sheet having a random shape and incorporating an internal reinforcement, as well as the thus obtained sheet
Inventor: MONTAGNE MARC H
IPC: B32B27/12
Filed: 1991-11-25
Abstract: DESCRIPTIVE ABSTRACT            For the production of a tight complex having an internal reinforce-ment or framework and more particularly intended for the production of aerostatic balloons, a nonwoven reinforcement (10) is formed from weft and warp threads arranged in the form of two superimposed layers.  To each of the faces of said reinforcement and using a predetermined force is applied a covering film (16a,16b), after bringing it to its pasty melting point on a heating drum (30a,30b). The nonwoven character of the reinforcement makes it possible to preserve the seal of the covering films during complexing.  More-over, the formation of small loops or rings on the edges of the complex obtained in this way makes it possible to introduce conn-ecting cables facilitating the taking up or absorption of stresses.
