Patent CA-2355575-A1 (CA)
Title: Thickeners with vibrating inclined plates
Inventor: OZUM BAKI
IPC: B01D21/00
Filed: 2001-08-03
Abstract: A thickener with vibrating inclined plates placed inside is disclosed for separating solids from feed liquor of suspended solids, by gravity settling, to form a thickened suspension as thickener underflow effluent and recovering clarified liquid as thickener overflow effluent. The thickener is composed of a liquid-holding tank of rectangular or circular geometry, preferably with triangular or conical bottom section. Inside the thickener, vibrating inclined plates are placed, preferable in the compression zone of the thickener. The number and geometry of the plates, and their inclination angles are adjusted depending on the sliding characteristics of the sedimenting suspension. The inclined plates vibrate continuously or periodically at selected vibration directions, amplitudes and frequencies. Thickener overflow or the clarified fluid, which is the process water for most of industrial applications, is collected in a launder and continuously discharged. Thickener underflow is the thickened suspension, which is continuously discharged from the bottom of the thickener using screw conveyer. The present invention can be used for thickening of suspensions by means of batch or continuous operating modes.

Title: Method for producing angular components consisting of flat-strip laminated sections
Inventor: BLEIBLER ALEXANDER
IPC: B29C53/56
Filed: 2000-01-14
Abstract: The invention relates to a method for producing angular components consistin g of flat-strip laminated sections for the retrofitted reinforcement of concre te structures. According to said method several monolayer supporting fibre laye rs which are embedded in a binding agent film (140) are drawn, wound or pressed  onto a shaping element (142, 144, 154) having at least one shaping edge (148 , 152, 155) such that they are superimposed on their broad sides and then compressed under the influence of pressure and heat until said layers are joined across their broad sides. After curing of the binding agent the composite part (158) produced in this way is removed from the shaping elemen t and divided into angular components (110) having defined leg lengths and/or widths.

Title: Update of header compression state in packet communications
Inventor: SUNDQVIST JIM
IPC: H04L1/00
Filed: 2000-02-25
Abstract: The soft state of a header compression scheme in a communication system carrying packet traffic including a real time communication signal can be updated (63) during periods of communication signal inactivity (62), during which there is no need to transmit the communication signal. The header compression soft state can also be updated by stealing bits (83, 84) from the communication signal to carry the header update information (73). If the communication signal includes source encoded data, the header compression soft state can be updated selectively (126) based on the bit rate (122, 124) of a codec that produced the source encoded data.

A locking mechanism (46) is operatively coupled to upper (30) and lower (36) tracks for movement between a locked and an unlocked position allow sliding movement therebetween. A cam plate (62) is pivotally coupled to one of the upper tracks for movement between a non-actuated position spaced from the locking mechanism and an actuated position engaged with the locking mechanism for maintaining the locking mechanism in the unlocked position in response to pivotal movement of the seat back from the reclined seating position to the forwardly dumped position. A trigger arm (84) interlocks with the cam plate in the actuated position to maintain the cam plate in the actuated position and thus the locking mechanism (46) in the unlocked position and allow sliding movement of the seat assembly to a forwardly extended position beyond the full forward seating position. A trigger tab (104) engages the trigger arm when the seat is returned from the forwardly extended position to the full rearward position to release the cam plate to the non-actuated position and allow the locking mechanism to return to the locked position interlocking the upper and lower tracks and preventing further sliding movement therebetween.

Abstract: A child's entertainment device can include a mobile/entertainment member that has a connector structure that can engage a receiving member located on a child support device. The connector structure can be formed as a button-like protuberance that engages the receiving member, which can be formed as a U-shaped aperture. The button-like protuberance is thus lockable in the U-shaped receiving member at a predetermined position while rotatable with the respect to the receiving member. In addition, the entertainment member can be removed from the receiving member by applying a force to it and moving the button-like protuberance past a slightly narrower portion and out of the U-shaped aperture. When the entertainment member is attached to the receiving member, the mobile/entertainment member and attached soft toys can spin and entertain a child. The mobile may be attached to a child support device such as a child's cradle, bassinet, swing, bouncer, or car seat, etc.

Abstract: An actuator for use with a lift truck having an extendible mast includes an elongated housing and an axial bore formed in said housing. The bore has a first end and a second end A ram is slidably and sealingly mounted in the bore for axial movement between an extended position and a retracted position, and has one end disposed in the bore and an opposing end extending out of the bore second end. A pressure ring is slidably and sealingly mounted in the bore between the ram one end and the bore second end, wherein filling the bore with a fluid causes the ram to move from the retracted position toward the extended position, and engagement of the ram one end with the pressure ring traps fluid between the pressure ring and the bore second end to resist movement of the ram toward the extended position. In a preferred embodiment the ram one end includes a piston plug body with an axial piston plug bore formed in the piston plug body. The piston plug bore has a first end and a second end, and the piston plug bore first end is in fluid communication with the bore formed in said housing. A piston is slidably and sealingly mounted in the piston plug bore, and has an end extending out of the piston plug bore second end toward the first end of the bore formed in said housing. An accumulator biasing member urges the piston away from the piston plug bore second end.
