Title: Forceps and calibration device
Inventor: TALBOT R ERNEST MARK
IPC: A61B17/04
Filed: 1988-04-05
Abstract: A forcep (eg. suture tying forcep) has limbs which, when compressed, meet at the tips (1). This compression, and therefore grip of the tips, can be limited by an adjustable stop (2) and ratchet system (5). The forceps release the body acted upon (eg. suture) once the tension in the body overcomes the forceps grip. No further increase in tension within the body can occur. By limiting compression of the legs, the tension within the body acted upon is similarly limited. Preferably a lug (3) is provided on one limb close to the tips (1). The closed tips can be opened momentarily by pressure at a point (4), so placed that the lug (3) acts as a fulcrum. <IMAGE>

Title: Method and installation for gas-jet treatment of bulk material
Inventor: KONSTANTINOVICH ARTEMICH VLADI
IPC: B02C19/06
Filed: 1990-08-21
Abstract: The proposed method, implemented by a gas-jet installation, provides for feeding the flows of the bulk material and a gas into chambers (1, 2) for obtaining a material-gas suspension. The obtained material-gas suspension is fed to Laval nozzles (13) of arrangements (11, 12) for accelerating the material-gas suspension gradually up to a supersonic speed. Simultaneously additional gas flow jets are fed, at a speed exceeding that of the material-gas suspension flows, through diffuser nozzles (17, 18, 19, 20, 21, 22), the cross-sections of which have the form of a rectangle whose larger axis crosses the longitudinal axis (34) of the Laval nozzle (13). At the moment when the material-gas suspension flow reaches a supersonic speed it is mixed with the additional gas flow and the obtained mixture is disintegrated and homogenized in a chamber (25) for disintegration and homogenization. Then the mixture is separated in a classifier (30) into a light and a heavy fraction, the latter then being recycled to the chambers (1, 2) for obtaining a material-gas suspension.

Title: Sterilising container head
Inventor: WILKINS JULIAN JAMES
IPC: A61L2/28
Filed: 1993-03-11
Abstract: The maintenance of sterility of sterile liquids e.g. drugs in containers during supply/removal of liquid to/from the containers, in particular by a transseptual technique, is enhanced by housing the head only of the container in an internal chamber 11 of a sterilisation body 10 to which sterilisation agent e.g. vapour followed by rinsing water and air is supplied. This sterilisation technique can be extended to tubes and/or needles utilised in supply/removal of such liquid to/from the container. When the liquid is toxic, a neutralising agent for a toxin may be subsequently supplied to the closed region. A sample needle 16 gains access through valved aperture 33 and advances through self sealing head 14 into container 15. A plurality of sterilisation bodies 10 may be mounted on the external side of a wall of a common sterilised chamber (41, Figure 4), access to the chamber being through an access panel (51, Figure 3). Each sample needle may be robotically controlled. Alternatively the sterilisation bodies may form part of an isolation unit consisting of two chambers (210, 220 Figure 6) within which liquid, eg from xoma nuts, may be dispensed into a container 290 through tube 270, the container centrifuged to separate out liquid phases and the desired phase withdrawn through needle 71.

Title: Joining bodies of thermoplastic material
Inventor: GREIG JOHN MARTYN
IPC: B29C35/08
Filed: 1993-04-01
Abstract: A pipe 10 of polyethylene is reinforced by two layers 12, 14 of polyethylene tape wound around the pipe in opposite directions under tension. The pipe contains carbon block and the layers are unpigmented and free from fillers and are transparent to infra-red radiation to which the first major surface 21 is exposed. The radiation is in the near infrared region and has a substantial part of the radiant energy of a wavelength of less than 2.5 micrometers. Very little radiation is absorbed by the layers but a very high absorption occurs in the outer surface of the pipe. This causes the interface between the second major surface 36 of the layer 12 and the first major surface 38 of the pipe and between the second major surface 28 of the layer 14 and the first major surface 30 of the layer 12 to reach temperatures at which fusion welding in the layers welds them together and welds the layer 12 and the pipe 10 together. <IMAGE>

Title: Testing vehicle door sealing strips.
Inventor: JUNKER BERND
IPC: B60J10/00
Filed: 1993-12-22
Abstract: A sealing strip (4,5) to be tested is mounted on a platten 22 connected to a force measuring unit 20. A height measuring unit 36 having a probe 40 extending through a hole 34 in a contact plate 32 measures the initial height of the sealing part. Contact plate 32 is then lowered so as to compress the seal by a predetermined amount. The resultant force is measured by the unit 20 and plotted on a pen-recorder which shows how the force gradually reduces over a period of time due to "relaxation" in the material of the seal. After a fixed period (e.g. 24 hours) the contact pressure is removed and the unit 36 in conjunction with the pen-recorder measure the height of the seal to which it resiles and the rapidity with which it reaches this height (Fig. 5). <IMAGE>
