Title: Handleset with adjustable latch retracting mechanism
Inventor: SOLOVIEFF PAUL G
IPC: E05C1/14
Filed: 1991-11-26
Abstract: A single handleset 10 with an adjustable retracting mechanism 11 includes a handle 20 and thumbpiece 32 which operates a rack 48. A pinion 70 is in mesh engagement with rack 48 at all times. A half round spindle 84 is connectable to pinion 70 in either of two positions determined by the right hand or left hand orientation of a door 18 to which assembly 10 is mounted. Spindle 84 is adjustable without decoupling pinion 70 from rack 48 to ensure proper orientation of the spindle relative to the pinion for effective operation of a latchbolt assembly 140. A double handleset 210 with the adjustable latch retracting mechanism 11 includes a pair of handle units 212 and 234 and also provides the versatility of adjusting spindle 84 independently of pinions 70 to accommodate either a right hand or a left hand orientation (Fig. 6, not shown). <IMAGE>

Title: Fibre preforms of varying thickness
Inventor: OLRY PIERRE R
IPC: B32B5/06
Filed: 1991-11-29
Abstract: In a portion of the preform to be made in which the preform is to be of reduced thickness by having a recess formed therein, a mask (181, 182, ...) is interposed between pairs of adjacent layers (121, 122, ...), the mask being made of a thin film of material through which the needles can pass during needling while opposing the passage of significant quantities of fiber taken by the needles, and after it has been needled, each layer is cut out around a line corresponding to the outline of the recess in the preform at the level where the layer is situated in the preform. A mask situated between two cutout layers occupies an area that is not less than the area between the cutout lines of the two layers, such that the portions of the layers (121, 122, ...) that are delimited by the cutout lines are not securely connected to the remainder of the preform by the needling, thereby enabling the recess to be formed after all the layers have been needled by withdrawing the cutout portions of the layers and by peeling off the masks. <IMAGE>

Title: Extruding a sheet of mixed pigment and regrind/virgin plastics,for thermoforming
Inventor: LOWE GRAEME
IPC: B29C48/07
Filed: 1991-12-31
Abstract: The components of the mixture are delivered from respective separate pigment, and regrind and virgin plastics hoppers 7, 8 6 into an infeed hopper 10, thence by delivery auger 15 into an extruder screw 5 which has a primary helical flight 41 and, in a transition zone 35, a secondary flight 46 which defines a channel 47 in which the material is thoroughly mixed. The diameter of the secondary helical flight 46 is approximately 99.17% of the diameter of the primary helical flight 41 and this achieves efficient material transfer into the channel 47 with reduced shearing and improved pumping action. The combination of the reduced diameter of the secondary flight 46 and the delivery auger 15 achieved efficient handling of materials with a high content of regrind material and change-over from one mix to another is achieved quickly with minimum wastage. <IMAGE>

Title: Eliminating frequency components
Inventor: ATTEW JAMES
IPC: H03H7/01
Filed: 1992-03-30
Abstract: A filter for eliminating a defined frequency component e.g. the chrominance component from a pulsed input video signal of width 2T has a filter 22 passing only said frequency and two adders 24, 28 each adding a portion of the filter output in phases respectively advanced and retarded by T/2, with respect to the outputs of delays 20, 26. The output of the filter has a better amplitude output in comparison to a simple band elimination filter and ripple components are evenly distributed evenly to the right and left to the output pulse. The filter may be modified to be an effective low pass filter by using a high pass filter in place of the band pass filter, 22. <IMAGE>

Title: Semiconductor dosimeter
Inventor: BLAMIRES NORMA GWYNNE
IPC: G01T1/02
Filed: 1993-01-08
Abstract: A MOSFET comprising a semiconductor substrate (10) defining doped source and drain regions (24, 26), with a gate electrode (22) separated from them by a layer of insulator or oxide (30), can be used as a dosimeter. The threshold voltage varies linearly with the dose received by the oxide layer over a wide range of doses. The sensitivity of such a dosimeter is greatly increased by implanting hydrogen ions into the oxide layer (30), subsequently maintaining the temperature of the MOSFET below 600 DEG C. Any anneal performed after the hydrogen ion implantation is desirably at no more than 400 DEG C.   <IMAGE>

Title: Sealing, trimming or finishing strips
Inventor: BAUMANN MICHAEL
IPC: E06B7/23
Filed: 1993-06-18
Abstract: A sealing, trimming or finishing strip (5), such as for mounting on an edge flange defining the frame of a closable opening in a motor vehicle body, comprises a channel-shaped extruded material (6) incorporating an embedded metal carrier (8) and defining inwardly directed sealing and gripping lips (10). In addition, a barrier seal (12), which is of triangular shape in cross-section and made of cellular material softer than material (6), is mounted adjacent the mouth of the channel. Because of its configuration and shape, the barrier seal (12) is able to follow abrupt changes in the thickness of the mounting flange, and thus prevents ingress of moisture or draughts which might otherwise be caused by such abrupt changes which may be bridged-across by the lips (10). <IMAGE>

Patent GB-2290275-A (GB)
Title: Seaplane hull
Inventor: LABOUCHERE JAMES
IPC: B64C35/00
Filed: 1994-06-18
Abstract: A seaplane hull has a high length/beam ratio, substantially fair topside waterlines from bow to stern and a fine bow entry angle. These characteristics disperse the water little, offering the hull low wave-making drag characteristics which enable it to achieve high speed without requirement for planing lift. Chines (4) on the underside describe a slim planing surface, the edges converging aft toward the central plane. The slim planing surface minimises wetted area at speed, and low pressure hollows (6) are provided immediately above the chines (4) for air to travel aft and under an afterbody when at speed. The design enables continuity of aerodynamic and hydrodynamic streamlines throughout acceleration to take-off speed.
Patent GB-2293332-A (GB)
Title: Vending carbonation
Inventor: COOK CHRISTOPHER MICHAEL
IPC: B67D1/00
Filed: 1994-09-20
Abstract: A carbonator for low use beverage dispensing systems is disclosed. Water 6 and carbon dioxide 5 are fed under pressure into vessel 1 until the pressure in the vessel equals the water inlet pressure thus establishing a pressure equilibrium, the water in the vessel is then cooled by refrigeration system 7 so that it absorbs carbon dioxide gas from the headspace 9. This causes the pressure in the vessel to drop and more water is automatically drawn into the vessel, this process repeats until the vessel is completely full of water and all the gas has been absorbed. The device provides a reservoir of carbonated water for beverage dispensing. <IMAGE>
