Abstract: In order to obtain an evenly flocked and an evenly coated surface of a strip-like elongated workpiece, any slack of the strip-like elongated workpiece is removed not to affect the workpiece when the workpiece travels through an electrostatic flocking and an electrostatic coating chamber at high speed. A slack of the workpiece occurs due to its own weight under the influence of gravity when the workpiece travels through the electrostatic flocking and the electrostatic coating chamber at high speed. A V-shaped oblique surface portion of the workpiece is forcibly defined by a pressure roller in a position corresponding to that of the slack of the strip-like elongated workpiece. An electrode is disposed in parallel to the workpiece's V-shaped oblique surface portion defined by the pressure roller.

Granted: 2012-11-06
Abstract: This invention is a device for controlling the discharge of a battery (B1) supplying an intermittent load, such as a nerve stimulation device. The device includes a controller (15) which operates a switched inductor (L1) to feed a capacitor (C1) with numerous small pulses from the battery, thereby building up the charge, voltage on the capacitor, and occasionally discharging the capacitor to a load. The capacitor discharge is at a current higher than that of the small pulses from the battery, so the battery is drained at small instantaneous discharge rates compared to the high instantaneous discharge current from the capacitor.

Title: Partial retrieval of images in the compressed domain
Inventor: LARSSON MATHIAS
IPC: H04N1/21
Filed: 1999-10-13
Granted: 2009-08-18
Abstract: In a method and a system for retrieving images in a client-server system, images are stored as a set of independently decodable units (CU's) on the server. A client issues a series of requests for image information. Each request contains a request number, information on what image information the client wants to see next and information on what image information the client had received at the time when the request was issued. The server does not have to store any state information (e.g. previous requests). On receiving a request, the server sends a restart marker, a confirmation of the request number and incremental image information corresponding to the request. The use of the method and the system as described herein will result in that no decodin g of the whole bit stream will be required in the server. This will save a lot of time at the sender side (server side), since it does not need a full decoding of the stream.

Abstract: The wellbore pump of the present invention comprises a plunger having passage means which may be open or closed by a valve operated by a piston which is biased in the open position by a spring of selected strength such that the wellbore pressure may overcome the spring to close the valve when the accumulated hydrostatic pressure reaches a certain value. When the valve closes the reservoir pressure forces the plunger to the surface and causes the accumulated liquids to be pumped out of the wellbore. A stem extending from the top of the piston engages a top plate and causes the valve to open when the plunger reaches the top of the wellbore. Means is provided whereby the valve opens when it reaches the top of the wellbore and a latch may be provided to retain the plunger from returning to the bottom of the well.
