Patent GB-2293297-A (GB)
Title: Dithered data coding
Inventor: EASTTY PETER CHARLES
IPC: G10L19/00
Filed: 1994-09-13
Abstract: Apparatus for processing an input digital signal to generate an output digital signal of a lower resolution, comprises means responsive to an indicator signal for adding a digital noise signal to the input digital signal to generate a dithered digital signal and for quantising the dithered digital signal to generate the output digital signal. The apparatus operates to vary the probability of at least one predetermined bit of the output digital signal being logical one or logical zero in dependence on a current state of the indicator signal. This allows the indicator signal to be encoded into the existing data stream of the output signal, and to be detected later by detecting a slight predominance of logical one or logical zero in the data. The indicator signal could be used, for example, to indicate that the digital dither noise was generated from the output digital signal, so that an identical noise signal can be later subtracted from the signal, or could indicate the title of an audio track or copyright origin information. Application is to digital recording and/or replay apparatus, such as a tape device or compact disc player. <IMAGE>

Title: Movable window safety device
Inventor: BRODOWSKY THOMAS
IPC: B60J10/04
Filed: 1996-05-03
Abstract: A movable-window safety device for arresting upward movement of a power-driven window glass in a motor vehicle body in the event of obstruction in the window opening comprises a resilient channel (16) for receiving the window glass (52). The base of the resilient channel comprises an electrical detecting member (50) housed in a hollow chamber (32). An obstruction in the window opening is carried upwardly by the window glass (52) and applies a force (F) to one or other of the side walls (17, 18) of the resilient channel (16), and hence to the detecting member (50). The detecting member (50) may be part of a capacitor in the tuned circuit of an oscillator whose frequency correspondingly varies in response to the resultant movement of the detecting member (50). Instead, it could be a member whose electrical resistance is changed by the applied force (F).

Title: Battery discharger unit, also usable for other purposes
Inventor: MORRIS DAVID GEORGE
IPC: G01R31/36
Filed: 1997-02-26
Abstract: A unit for discharging rechargeable Ni-Cd batteries to overcome memory effect has a housing containing a twin filament lamp 5 which presents a discharging load of 105 watts to a battery connected to a cable 2. A fan 8 draws air through the housing and is connected to the cable 1 via a bridge rectifier 7 allowing any polarity connection of the battery to the cable 1.

Alternatively, test leads can be connected to the unit to allow use as a 12 volt live circuit tester, or as a dead circuit tester if a 12 volt battery is additionally connected in series with the unit and circuit under test. The unit could also be used as miniature heater, in which case the lamp 5 may be an extra high wattage type, or a heat emitting diode may be used instead of the lamp.
Patent GB-2315476-A (GB)
Title: Yarn package transport system
Inventor: TSUZUKI KIYOHIRO
IPC: B65G47/24
Filed: 1996-04-30
Abstract: A package transport system (1) is provided for transferring yarn packages from a textile machine (2) to a transport conveyor (4). Textile machine (2), which is either an open end spinning machine or a winding machine, has conveyor belts (14, 16) for transporting yarn packages from rows of spinning stations or winders to chutes (18, 20), after which they fall by gravity onto transport conveyor (4). A delay mechanism comprising controller (C); sensors (100, 102) connected to controller (C); and switches (110, 115), also connected to controller (C), prevents yarn packages delivered via chutes (18, 20) from colliding. If textile machine (2) is a winding machine, yarn packages traveling from winders to chutes (18, 20) have a sharply angled narrow portion on one side, making them easily susceptible to unwinding and tangling if the angled side is the first to enter chutes (18, 20). In this scenario, a reorienting mechanism can be employed to rotate the yarn packages 180‹ prior to their entrance into chutes (18, 20).
