Title: A hinged hatch roof assembly for a vehicle cab
Inventor: MEYER RAYMOND JOSEPH
IPC: B62D25/10
Filed: 1982-08-30
Abstract: A hinged hatch assembly for the roof of a vehicle cab having an opening formed therein. The assembly includes a hatch which completely covers the opening when in a closed position. The hatch is connected to the roof of the vehicle cab by a pair of support arms. Each support arm contains a first and a second forked end whereby the first forked ends are pivotally attached by brackets to one side of the roof opening and the second forked ends are pivotally attached by brackets to the underside of the hatch. Sandwiched on each side of the brackets between the forked ends of the support arms are frictional elements which are spring loaded to impart a predetermined frictional force on the members. The frictional contact permits the hatch to be opened at various angles and at various positions relative to the plane of the roof and to remain in the desired position irrespective of any vibration or motion imparted into the vehicle. The hinged hatch roof assembly is capable of providing ventilation as well as serving as an escape route from the interior of the vehicle cab.

Title: Method and apparatus for deinking
Inventor: NANDA ASHOK KUMAR
IPC: D21B1/08
Filed: 1984-03-23
Abstract: In a deinking process for a fibre stock or slurry air is introduced into the slurry so that air bubbles and ink come into contact, and the ink-laden bubbles are then separated from the slurry. 
<??>In order to provide an improved separation process the invention proposes to independently control the air injection, the mixing of the air and slurry, and the separation process by splitting them into separate steps so as to optimise the separation process. 
<??>Thus, there is provided a separation cell (31) which is fed with slurry from an inlet, an air inlet device, which in one embodiment comprises a porous sintered sleeve (7) to which air pressure is applied, and a mixing section which imposes turbulent flow on the air bubbles and slurry by passing the constituents through a series of turbulence discs (39). The resulting mixture enters the separation cell where the ink-laden bubbles rise to the surface as a foam which is conveniently removed by suction. The reinked slurry being drawn off from the separation cell.

Title: Coated sodium percarbonate particles a process for their preparation and their use
Inventor: BERTSCH-FRANK BIRGIT
IPC: C11D17/00
Filed: 1994-07-15
Abstract: In the prior art, sodium percarbonate is coated with compounds which produce a stabilizing action in order to increase the shelf life. There is a need for an improved, boron-free, coating for sodium percarbonate. Proposed by the invention is a particle coating containing sodium carbonate plus one or more optionally partly hydrated magnesium compounds, preferably magnesium sulphate, in a single coat or in separate coats. The coating preferably contains two coats. The particles are produced by spraying aqueous solutions containing the coating compounds on to sodium percarbonate in a fluidized bed and at the same time evaporating off the water. Their long shelf life makes particles coated in this way suitable for use in washing, bleaching and cleaning agents.

Title: Method and apparatus for automatically determining an isp local access number based on device location
Inventor: MOON BILLY GAYLE
IPC: H04W4/02
Filed: 1998-09-30
Granted: 2002-06-05
Abstract: A local access number is automatically determined for facilitating communication between a portable communication device and one or more local service providers. A new location of the portable communication device is detected, and a determination is made whether a local access number is stored in the portable communication device for the new location. If the local access number is not stored, the new location of the portable communication device is reported to a location server in the local service provider serving the new location. The location server provides an appropriate local access number for the new location, and this local access number is stored in the portable communication device.

Abstract: In a process for perforating smooth, skinned surfaces of open cell plastic foams, an extruded plastic foam sheet (16) is heated, vacuum formed, cooled and one of the facing skins (12,13) is perforated by needles (4). Process equipment has a tool part (11) with fixed or movable needle (4) in a matrix pattern. Needle tips (18) extend above the tool (11) surface during perforation. Pref. in process variations (i) the sheet (16) may be coextruded with a coloured or uncoloured facing layer of similar or dissimilar material to the sheet (16) before vacuum forming and perforating or (ii) the plastic sheet (16) itself is extruded without facing layers. Needling may be performed before or after sheet (16) thermoforming. Needles (4) may oscillate backwards and forwards or are fixed in a tool block which is moved towards the sheet (16) supported on a backing plate. In an alternative process perforating is effected by needles on a rotating roller, prior to thermoforming. A container can be perforated in both sidewalls and base by needles moving perpendicular to the respective surfaces. In a further alternative process the thermoformed prod. is moved to a perforating station and pressed against a fixed plate by moveable perforating blocks. Needles fixed to a plate are then raised to perforate the prod. resting on the perforating block.
