Rubber plug prodn. for a vial is such that a synthetic resin film is laminated on the leg side of a rubber plug. The prodn. method comprises (i) a first formation step of superposing a synthetic resin film (1) resistant to medicines or to medical chemicals onto an unvulcanised rubber sheet (2) and pressing, heating and shaping them between moulds (A, B); (ii) a second formation step of putting an ...

Biomaterials useful for onthopedicanel dental applications is disclosed. These materials have a base portion of calcium carbonate and a surface layer of a synthetic phosphate such as hydroxyapatite. The base portion may be a calcium carbonate structure having three-dimensional interconnected porosity such as may be found in porous skeletal carbonate of marine life, e.g. coral porites skeletal arag...

The system includes one or more transceiver units in one or more remotely controlled objects and an external transceiver unit integrated in a wrist watch. The watch includes function keys for entering information, while a remote controlled object can be mounted in a motor vehicle to trigger an alarm during a disturbance of the vehicle. The keys on the wrist watch can be used to actuate the car wi...

An elongated pile article having a support strand (32) for attachment to a plurality of yarn bundles (20), the yarn bundles including a dense portion with the filaments bonded to each other and bonded to the support strand, a pile surface structure comprised of a plurality of elongated pile articles placed one next to the other, and a method and apparatus for making the elongated pile article.

The core of a piece of a conventional rope is withdrawn and a stiff rod is inserted as a new core (6). The stiff rod (6) may have a dry coating of a thermosetting glue so that the strands (7-9) will be fixed to it when heated. The decorative rod can be used for example as a curtain rod, as a curtain tie-back, or as a hand rail.

Painted metal sheet pretreated with an insoluble, composite layer containing siloxane. The composite layer is formed by rinsing the sheet with an alkaline solution containing at least 0.005M of a dissolved silicate or a dissolved aluminate, at least 0.1 vol.-% of an organofunctional silane and at least 0.02 vol.-% of a crosslinking-agent having two or more trialkoxysilyl groups. After the sheet is...

A lens assembly is connected to a housing containing an image sensor by a flexure means which provides for universal flexure of the lens assembly relative to the housing. A pair of compound screws rigidly couple the lens assembly to the housing and are rotatable to displace the lens assembly relative to the housing on said flexure means.

In a data processing system including bulk storage and paging storage, a two 64-pair DLAT structure is used, one for 4KB pages and one for 1MB pages. Each DLAT is two-way set associative with pairs of entries, each entry representing a page. The DLATs are interrogated in parallel by a hash combination of appropriate intermediate virtual address bit and each entry includes a high order page identif...

A dolorimeter apparatus comprises a member having a property which varies according to pressure applied to the member. A device is provided for securing the member to a hand of a user so the member fits under a finger of the user. The member is dimensioned to fit between the finger and an object touched by the user while permitting substantial tactile communication to the finger. A device is provi...

An expandable memory structure, both vertically and laterally, which uses a plurality of uniformly sized and duplicated chips which includes parity check functionality using an auxiliary parity memory chip of the same type and size. Selection circuitry permits choice of format for odd or even parity.

The blood is passed through a haemofiltration element (2) and a haemodialysis element (3) in cascade and the ultrafiltrate (7) output from the haemofiltration element (2) is passed through a filter (11) such as an activated carbon filter, preferably with uncoated activated carbon. The ultrafiltrate thus purified can then be used as a reinfusion solution (8) to be readministered to the patient.

A hemodialysis system has a blood circuit and a hemofiltrate circuit interconnected at a hemofilter and an air collection chamber. If an infusion of sterile fluid to the returning blood is needed during the dialysis treatment, filtrate in the filtrate circuit is pumped back into the blood circuit. This is also done to purge the blood circuit of blood and return it to the patient at the conclusion ...
