Abstract: 2129539 9414251 PCTABS00032 A satellite communications network tuning system which consumes very little communications bandwidth. The network has a first terminal (10) for transmitting and receiving signals, a second terminal (20-1, 20-2) in communication with the first (10) for transmitting signals and a satellite (22) for receiving signals from the terminals and retransmitting them. The frequency of the retransmitted signals is offset from the frequency at which the signals were received. A method according to the present invention for compensating the transmit frequency of the second terminal (20-1, 20-2) for the satellite frequency offset comprises transmitting a signal from the first terminal (10) to the satellite (22) at a first frequency, receiving the retransmitted signal from the satellite (22) at the first terminal (10) at a second frequency, the second frequency being offset from the first frequency by the satellite (22), measuring, at the first terminal, the difference between the first frequency and the second frequency to obtain an offset, transmitting the offset from the first terminal (10) to the second terminal (20-1, 20-2), and adjusting the transmit frequency of the second terminal (20-1, 20-2) using the offset.

Abstract: The proposal is for a device for injection moulding plastic items enclosing hollow spaces with which a further pressurised medium like air, gas or a fluid can be introduced through a hollow needle (5) at a point differing from the nozzle into a mould (1), the mould hollow or cavity (4) of which can be filled with molten pastic through a nozzle. There is a needle core (9) which can be moved axially to a limited extent in the hollow needle (5) and it is possible via this needle core (9) to vary the cross-section of or open and close the aperture (16) of the hollow needle (6) opening into the mould hollow or cavity (4). The needle core (9) bears a thickened head or plate (10) in front of the end of the aperture in the hollow needle, the outside diameter of which corresponds at least approximately to the outside diameter of the hollow needle, so that it forms, with the aperture end (6) of the hollow needle (5), a radially directed splitting valve. In relation to the hollow needle (5), the needle core (9) is axially supported by spring means (23). It is important here that these spring means (23) continuously engage with the needle core (9) in the closing direction of the aperture of the splicing valve (16) and that the needle core (9) can be moved against the spring means (23) in the opening direction by a remote-controlled driving device (17, 18).

A mechanical jack (68) is operatively connected to the base frame (12) and the linkage for moving the mattress frame between high and low positions. The mechanical jack (68) includes a housing (72). A bear-ing (86) supports a ram (70) within the housing (72) for extension and retraction. A drive plate (90) and a hold plate (92) define apertures (146) through which the ram (70) extends. A drive bar (114) is shifted by rotation of an actuator shaft (82) to lock the drive plate (90) to the ram (70) and extend the ram (70) from the housing (72). A drive spring (102) resiliently biases the drive plate (90) to un unlocked or return position. A hold spring (106) biases the hold plate (92) to prevent return movement of the ram (70) into the housing (72). A release bar (112) is shifted into engagement with the hold plate (92) upon reverse rotation of the actu-ator shaft (82) to release the hold plate (92) and permit lowering of the ram (70) into the housing (72).

Abstract: A process is provided for continuously applying a substantially uniform and smooth filler of a water-based filler material to underlying wood substrates. The process comprises introducing the underlying wood substrates into a filler application area. Then, the initial temperature of the outer surface of the underlying wood substrates is determined. Prior to applying the water-based filler material, the initial temperature of said water-based filler material is determined. Prior to applying same to said underlying wood substrates, the initial temperature of the water-based filler material is continuously adjusted, based on the initial temperature of the underlying wood substrate, so that the final temperature of the water-based filler material of the outer surface of the underlying substrate is maintained. The water-based filler material is continuously applied to the outer surface of the underlying wood substrates in the filler application area. Underlying wood substrates that are substantially uniformly and smoothly coated with said water-based filler material are formed by this process.

Abstract: Method and apparatus are provided for separating coarse and ultrafine solids from a liquid stream to produce a substantially dry solids discharge and a clarified liquid. Apparatus is provided comprising a combination of a settling tank, a plurality of filter screens spaced along an endless link-chain conveyor, a screen vibrator and directed air streams. In operation, coarse solids settle preferentially to the tank bottom. Ultrafines solids remain in suspension. Relatively coarse filter screens are conveyed from a point outside the tank to traverse a prolonged path through the liquid. Ultrafine solids are captured on the screens, by filtering the liquid through an ever finer build-up of filter cake. The relatively large number of passes of the screens through the liquid provides effective filtering of suspended solids. Further, the screens dredge settled solids from the tank bottom. After exiting the liquid, collected coarse and ultrafine solids are dewatered by vibration of the screens and directed blasts of air. Dewatered solids are dumped external to the tank and clarified water is recovered from the tank. Enhanced polymer flocculation may be practised to form flocs from ultrafine solids, after which flocs may be collected (filtered/dredged), dewatered and dumped using the invention. Dewatered solids can further be subjected to compression and decompression cycles to separate even more water from the solids.

Title: Method of cooling multilayer preforms

IPC: B29B13/04

Granted: 2007-05-08
Abstract: Method of making multilayer preforms which resist delamination and in a reduced cycle time. A first array of preforms are molded onto a first array of cores in an associated array of mold cavities, the cores and preforms are removed from the mold cavities as soon as possible without significant physical preform deformation, and the preforms are then cooled on the cores while a second array of cores is positioned in the mold cavities. Cooling on the cores prevents delamination of the preform layers and reduces the in-mold cooling time. Providing multiple sets of cores on a rotating turret further reduces the cycle time compared to the prior art use of robotic cooling tubes.
