Title: A cutting instrument
Inventor: LASNER JEFFREY
IPC: B26B13/14
Filed: 1984-05-24
Abstract: A cutting instrument is formed of a single elongated strip (12) of resiliently flexible material having a bend (14) to define first and second shanks (16, 18) respectively, carrying a blade (20) and a shearing portion (28) at their corresponding ends. The blade includes a cutting section (22), and the shearing portion includes a cutting edge (30), and the blade and shearing portion are pivotally connected at (32). In one embodiment an elongated suture gripping element (50) unitarily depending from the shearing portion includes a contact area (54) for suture gripping contact with the cutting section during an operating stroke or jaw closure of the instrument. In another embodiment there is a cutting blade and a shear blade forming a scissors, with each blade having an elongated raised rib, and an abutment shoulder. The ribs render the blade tips inflexible and bow the blades relative to each other, in order to provide edge-to-edge contact between the blades. <IMAGE>

Title: Device for venting gaseous and/or vaporous media
Inventor: MARTIN WILLIAM STEPHEN
IPC: F16K17/12
Filed: 1984-09-11
Abstract: A device for venting a gaseous and/or vaporous medium into the atmosphere comprises a tubular framework defining a vent 1a for flow therethrough, and valve means associated with the vent 1a to provide a vent orifice of variable cross-sectional area. The valve means comprises at least one flap 7b, 8b pivotally mounted on said framework for varying the volumetric rate of flow. Biassing means, such as the counterweight 38, is associated with the flap 7b, 8b for urging the latter into a position to close the vent orifice and prevent opening of the orifice until a predetermined first pressure differential is established on opposite sides of the flap 7b, 8b. Further means, for example magnets 45 and associated armatures 47, is associated with the flap 7b, 8b for holding the flap in the orifice closed position until a second and higher pressure difference is established on opposite sides of the flap 7b, 8b, this further means becoming inoperative when the vent orifice opens. <IMAGE>

IPC: H04N9/12
Filed: 1985-04-22
Abstract: An image enlarger for a cathode ray tube has a curved concave face 3 on one side to fit against the face- plate 5 of the CRT and a display face 4 on the opposite side. The enlarger comprises an assembly of light guides in the form of adjoining elongate cells 2 with open ends and internally reflective walls, extending radially with respect to the concave face 3 of the enlarger so that the display face 4 is larger than the concave face.

Title: Flow centrifuge for liquids-solids separation
Inventor: WILLIAMS RAYMOND
IPC: B04B11/04
Filed: 1985-10-22
Abstract: To ensure optimum filling of the bowl (24) of a continuously operating centrifuge, the bowl mounting structure (2, 5, 6) is supported by springs (7, 8) for vertical displacement and is co-operable with a magnetic transducer (21) for providing a read-out corresponding to such displacement, in operation, and hence the instantaneous weight of the contents of the bowl. An electronic filter (28) in the line from the transducer removes any interference at frequencies other than the rotational frequency of the bowl, such as might arise from axial oscillations. The bowl is driven by air-turbine (3) rotated by air jets (4). The sensing system may provide feedback to maintain a constant rotational speed. <IMAGE>

Patent GB-2175291-A (GB)
Title: Organoclays
Inventor: TATUM JOHN P
IPC: C01B33/20
Filed: 1986-05-06
Abstract: An organoclay material adapted specifically for use in a given system is selected by testing the system with organoclays made using a range of quaternary ammonium compounds having varying average carbon chain lengths, particularly by reacting suitable clays with mixed quaternary ammonium compounds, in order to determine the optimum C to N ratio in such quaternary ammonium compounds for that system. An organoclay is then manufactured substantially in accordance with the optimum ratio by utilising one or more selected quaternary ammonium compounds designed substantially to achieve the optimum C to N ratio or a single quaternary ammonium compound which affords said C to N ratio.

Patent GB-2191291-A (GB)
Title: Magnetic pick-offs
Inventor: PIERCEY ALFRED WILLIAM
IPC: G01D5/26
Filed: 1986-05-17
Abstract: In order to avoid the use of wires connecting the pick-off to an external power supply or to a remote controller or indicator, the pick-off comprises a casing, a sensing coil 2, within the casing, and a light source 3 disposed within the casing in close proximity to the coil 2 and electrically coupled to the coil 2 so as to be powered by the sensing current from the coil 2. A light signal proportional to the sensing current may thereby be transmitted to the remote controller 5 or indicator by way of an optical communication link 4 without requiring the supply of power to the pick-off from an external power supply. This arrangement substantially eliminates the problems of the pick up of external electromagnetic interference by the wires. <IMAGE>

Title: Lock arrangement for cartons
Inventor: SUTHERLAND ROBERT L
IPC: B65D71/00
Filed: 1987-01-13
Abstract: This relates to a lock arrangement particularly adapted for use in locking together closure panels of paper board cartons and the like. The lock arrangement utilizes a conventional basic type of lock including a primary locking tab and a secondary locking tab. The primary locking tab engages in a cutout having as part of its boundary a straight line primary locking shoulder. The new feature of the lock arrangement is an arrangement for receiving the secondary locking tab. This arrangement is in the form of a cut line which will define an opening through the associated closure panel and also define a secondary locking ear for engagement beyond a prong on the secondary locking tab. The closure panel in which the cutout and the cut line are formed is provided adjacent the cut line either with an opening or a hinged locking flap with there being between the cutout and either the opening or the locking flap a narrow strap. When a nose of the secondary locking tab engages the panel between the narrow strap and the cut line, the panel is locally bowed through a twisting of the narrow strap facilitating the opening of the panel along the cut line so as to automatically receive the nose of the secondary locking tab.
