Title: An Inorganic Support for an Enzyme Immobilisate
IPC: C12P13/04
Filed: 1978-11-01
Abstract: The invention is concerned with enzyme immobilisates, and provides a modified inorganic element which is suitable for use as the supportive substrate of such an immobilisate. The modified element of the invention is in the form of a shaped element of amorphous silica treated with an alkoxy silane which contains an amino (including cyclic amino) group.

Title: Impregnating a fibrous web with liquid
IPC: B29B15/12
Filed: 1978-12-20
Abstract: A moving fibrous web 94 is impregnated with a liquid by placing the liquid on the surface of the web (at 83), spreading the liquid over the web surface (by the action of member 124), pressuring a portion of the liquid into the web to partially saturate the web with the liquid and leave residual liquid on the web by contacting the spread liquid 83 with a surface 125 converging with the web, and metering the residual liquid into a layer of substantially uniform thickness under the action of parallel surface 126. This layer is then forced into the web to saturate it with liquid, e.g. at 134 where the web is wound spirally round a mandrel 10 for producing plastic pipe incorporating at least one layer of fibrous material saturated with liquid resin. There may be a plurality of projections of substantially uniform height on the trailing edge 129 of the surface 126 to ensure that the residual liquid is metered into a layer of substantially uniform thickness. <IMAGE>

Patent GB-2009835-A (GB)
Title: Hinged panel assemblies
IPC: E05D15/46
Filed: 1978-12-29
Abstract: Movable panels may be provided in vehicles such as buses and coaches to close openings to engine and luggage compartments and the like. If the panels are mounted on simple hinges, to allow access to the compartment space is required to accommodate the swinging panel, and this amount of space may often not be conveniently available, for example where vehicles are parked close together. So that less space is required, a panel 3 is mounted on a pivotally mounted extensible strut 4, and a control link 8, pivotally connected to each of the panel and the vehicle body 1, controls the panel movement. Preferably there are two control links connected by a torsion bar 14 and two struts 4, the struts being mounted adjacent opposite side edges of the opening into the compartment. Biasing gas springs may be associated with the struts 4, the gas springs incorporating a releasable locking arrangement to maintain the panel in an open position. <IMAGE>

Patent GB-2020750-A (GB)
Title: Rotary compressor
IPC: F04C29/02
Filed: 1979-06-13
Abstract: A compressor of the sliding-vane eccentric-rotor type discharges a mixture of oil and compressed gas through a delivery port (81) into a portion of a compressed-gas reservoir containing a series of longitudinally-extending flanges (150, 151 and 152) integral with a casing (16) and a flange (156) integral with a stator (60). The flanges promote precipitation of gas-borne oil droplets, the precipitated oil passing through a narrow gap (155) to the sump. The delivery port (81) directs the discharged mixture obliquely against the flange (151) to promote turbulence. The compressed gas and remaining gas-borne oil droplets then pass through a narrow gap between the flange (152) and the stator (60) into a settling chamber (157) in which further oil droplets are precipitated and returned to the sump through a narrow gap (158). The casing also accommodates an oil separator (48). <IMAGE>
