Title: Error concealment in digital television signals
IPC: H04N9/64
Filed: 1984-09-18
Abstract: Concealing errors in a digital television signal, which has a plurality of component sample values corresponding respectively to sample positions along a horizontal scan line of a television picture made up of a plurality of scan lines, in respect of each sample value which is in error, by calculating a first concealment accuracy by determining the difference between two immediately adjacent sample values both in the scan line immediately preceding or following the scan line which the error sample is in, and one of which sample values is immediately adjacent to the error sample, calculating a second concealment accuracy by determining the difference between two immediately adjacent sample values both in the vertical line immediately preceding or following the vertical line which the error sample is in, and one of which sample values is immediately adjacent to the error sample, selecting from the available concealment accuracies a preferred direction of the television picture for concealing the error sample, calculating a corrected value of the error sample using available sample values disposed along the preferred direction, and substituting the corrected sample value for the error sample so as to conceal the error.

Title: Apparatus & methods for analysing transitions in finite state machines
IPC: G10L15/14
Filed: 1988-10-19
Abstract: In speech recognition words to be recognised may be represented by finite state machines and recognition is based on analysing transitions through the machines as an utterance occurs. One value which is required for each state of each machine in a timescale which is compatible with continuous speech recognition is minimum cumulative distance; that is the smallest value on reaching one of the states from a starting position, considering all possible paths. In the present invention a specially constructed Viterbi engine is provided for calculating cumulative distances at high speed. Latch circuits 50, 51, 52 holding pointers allow a RAM 41 to be read to provide, for a current machine state, both stored cumulative distances of states with transitions. A logic circuit comprising latch circuits 60 and 65 and an ALU 61 finds the cumulative distance for each path as far as the current state, selects the minimum using a latch circuit 56 and adds another penalty dependent on the current state. Thus a minimum cumulative distance is provided for storage and for a speech recognition decision making circuit. The process is repeatedly carried out for each state of each machine under the control of a controller 45. The total number of iterations of the engine in reaching each mimimum cumulative distance is also held in the RAM 41 and updated by the logic circuit. <IMAGE>

Patent GB-8903775-D0 (GB)
Title: Tankwasher
IPC: B08B9/093
Filed: 1989-02-20
Abstract: A washer is described for cleaning the interiors of tanks that hold milk, beer, chemicals and so on. A main body 2 reciprocates relative to a substantially surrounded and relatively fixed piston 19. The body 2 oscillatably supports three nozzles 7 each of which is movable through an arc of 60 DEG  and which arc is angularly spaced from those corresponding to the other two nozzles 7 by further angles of 60 DEG . However, the body 2 and nozzles 7 are also indexed, during operation, in steps, around a further axis which is perpendicular to the axis of oscillation and which substantially corresponds to the longitudinal axis of the tank washer itself. Thus, each nozzle 7 cleans not only on arc of 60 DEG  but rotates that arc through 360 DEG  so that the whole of the interior of a tank is both washed and subsequently rinsed by the three nozzles 7.
Patent GB-9019416-D0 (GB)
Title: Device for applying torque to a tubular member
IPC: E21B19/16
Filed: 1990-09-06
Abstract: A device for applying torque to e.g. a screw-threaded pipe includes a pair of gripping jaws (24) pivotally mounted on a cage (16) and carrying respective followers (27) engaging cam surfaces (28) on the radially inner surface of a rotary drive member. The jaws have friction linings (29). The cage is connected to a clamp on the pipe so as to prevent rotation of the cage relative to the pipe. When a rotary drive is transmitted to the drive member, its cam surfaces operate the gripping jaws to clamp them about the pipe and increases the clamping pressure until the pipe begins to rotate with the drive member. The rotary drive member is mounted on a primary support which is held against rotation about the pipe and provides the required reaction force for the rotation. <IMAGE>

Title: Signal switching
IPC: H04B1/38
Filed: 1999-09-08
Abstract: A television or other signal is received via main and duplicate feeds into respective buffers. Should the main feed suffer interruption or disturbance the output is switched at a switch over to the duplicate feed, but in a staged process. Upon initial detection of disturbances read-out from the main buffer is performed using locally generated timing signals in lieu of timing signals obtained from the incoming signal. If however the disturbance s persist the two buffers are synchronized and switchover performed.

Filed: 1995-05-24
Abstract: PCT No. PCT/EP95/01972 Sec. 371 Date Apr. 3, 1997 Sec. 102(e) Date Apr. 3, 1997 PCT Filed May 24, 1995 PCT Pub. No. WO96/01933 PCT Pub. Date Jan. 25, 1996Scaffoldings are usually either movable or fixed. Structures usable for both are usually too bulky and complicated, and therefore not suitable for general use. The invention provides a solution because the platforms are interchangeable on the scaffolding frames and the frame components are equipped with a grid for the connection components of the other structural components involved. The frame components are thereby, in spite of the extensive use of light structural sections, extraordinarily torsion resistant. The invention can be designed to be extensively modular.

Patent IT-8123327-D0 (IT)
Inventor: PEFLEY RICHARD KRAMER
IPC: F02B13/08
Filed: 1981-08-03
Abstract: System for improving performance of spark ignition, internal combustion engines using fuels such as liquified petroleum gas (LP-gas), which have conventionally been stored as a liquid and delivered to the engine as a vapor. This system stores such fuels as liquids (10) and delivers the fuel to the engine inlet air stream as a liquid. The absorption of heat by the vaporizing fuel lowers engine inlet air temperature, increasing its density and permitting more fuel to be burned in each cycle. Vaporizing heat in a pilot line (17) provides the cooling to the liquid fuel in the main fuel line (20) and provides fuel to maintain the engine idling. A member (27) slides within a fuel delivery chamber (25) for covering or uncovering a series of orifices (26) through which the liquid fuel passes into the inlet air stream of the engine.
