Patent CA-2015407-A1 (CA)
Inventor: BIELFELDT FRIEDRICH B
IPC: B30B5/06
Filed: 1990-04-25
Abstract: A continuously-operating press suitable for producing chipboard, fibreboard, plywood or similar products.  The press has flexible endless metal bands serving to transmit pressing force to, and to pull the material to be pressed through, a pressing zone of the press.  The metal bands are guided over drive rollers and guide rollers around a press bed on one side of an adjustable pressing gap and around an upper pressing block on the other side of the pressing gap. The metal bands are supported on roller rods whose axes run transversely to the direction of travel of the bands, the rods being positioned between the metal bands and the pressing bed or the upper pressing block.  The bands have a thickness "d" of more than 2 mm and the rolling rods have a diameter "D" of more than 20 mm.  The extremities of the rods are associated with links of guide chains.  The rods and the links are each driven by feed sprockets in such a manner that the rods and links are fed co-axially into the pressing zone.  The feed sprockets associated with the pressing bed and those associated with the upper pressing blocks are co-ordinated in such a way that adjacent upper and lower rolling rods have medial axes substantially aligned in the direction of the application of force across the pressing gap.

Title: Speech coding system and a method of encoding speech
Inventor: MOULSLEY TIMOTHY J
IPC: G10L19/12
Filed: 1990-08-13
Abstract: A speech coding system of the code excited linear prediction (CELP) type comprises means (24,26) for filtering digitised speech samples to form perceptually weighted speech samples.      Entries in a one-dimensional codebook (110) comprising frame length sequences are filtered in a perceptually weighted synthesis filter (28) to form a one-dimensional filtered codebook (38). The filtered codebook entries are compared with the perceptually weighted speech signals to obtain a codebook index which gives the minimum perceptually weighted error when the speech is resynthesised. Using a one-dimensional codebook (110) reduces the amount of computation which is required compared to using a two-dimensional codebook.

Title: Process for producing a liquid-crystal cell
Inventor: BROSIG STEFAN
IPC: G02F1/1337
Filed: 1990-09-27
Abstract: ABSTRACT               Process for producing a liquid-crystal cell In a process for treating an organic orientation layer on a substrate plate for a liquid-crystal cell, the orientation layer for causing the orientation is rubbed in the conventional way in a specified direction. Rubbing is then performed in the opposite direction, but with a weaker rubbing pressure.   It has emerged that rubbing in the opposite direction with weak pressure leads to an increase of some degrees in the pretilt angle, and this is essentially independent of the material used for the orientation layer.
Patent CA-2033482-A1 (CA)
Inventor: GRATTAN MICHAEL A
IPC: B41J2/11
Filed: 1990-12-31
Abstract: An electronically controlled marking system is provided to impart an ink spot to a stationary or moving target.   The system includes an electronic control module connected to a high-pressure gas valve to control the passage of high-pressure gas to an ink spot marker, the electronic control module also being connected to a low-pressure gas valve to control the passage of low-pressure gas to the ink spot marker. Following the  initiation of  an  ink spot marking cycle,  low-pressure gas is applied to atomize ink within the ink spot marker;  high-pressure gas  is applied to force open a valve within the ink spot marker, thereby allowing ink to be ejected by the low-pressure gas toward the target; the high-pressure gas is removed to terminate the ejection of ink from the output nozzle, the low-pressure gas still being applied to force any remaining ink from the output nozzle;  and  the  low-pressure  gas  is  removed. Provision is also made for pulsing the high-pressure gas applied to the ink spot marker during the period that  ink is being ejected to provide pulsed  ink ejection.

Filed: 1990-03-08
Abstract: An expandable garment hanger with which the invention is concerned has a body (1), a hook (2) on the body to suspend the hanger and a pair of movable arms (3, 4) slidably mounted on the body. The arms are arranged to move in opposite directions. A locking device (8, 9) is located on the body (1) of the hanger so as to lock the movable arms relative to the body. The locking device is movable along a path parallel to the path along which the arms are movable. A biasing device, preferably a spring (27), is provided for biasing the locking device (8, 9) against movement in one direction so that when the arm of the hanger is set and locked in position the arms of the hanger are movable against the biasing force of the spring (27). The hanger conveniently supports garments of varying waist widths and maintains the hanger at the desired widths once the garment is mounted on the hanger but also allows the garment to be removed from the hanger by a small inward force applied to the end of the arm.
