Abstract: ABSTRACT      A chair frame arrangment has a locking mechanism between an adjustable and fixed frame parts.  The locking mechanism is of simple construction and is easy to operate and has a locking pin extending through a frame wall while passing to one side of the wall through a set of lamellae which may move freely in an unlocked pin position.  The locking pin has a locking spring on the outside of the wall to urge the pin into its locking position in which a sleeve on the other side of the wall is held against one side of the set of lamellae to clamp and lock them in position.  An operating lever is carried upon the outside of the wall and is operational to release spring pressure to allow for adjustment of the adjustable frame part.  A mounting is provided for the locking spring and in desired structures this also carries the lever and provides a clamping element which acts on the other side of the set of lamellae to take the clamping pressure of the sleeve.  The lever acts against a profiled cam surface at an adjacent end of the locking pin to overcome the action of the locking pin so as to move the pin out of its locking position.

Patent CA-2132039-A1 (CA)
Inventor: BURNS MARVIN D
IPC: B05B7/08
Filed: 1994-09-14
Abstract: For an HVLP paint spray gun, an improved suction feed nozzle assembly including a fluid tip and an air cap. The air cap directs an annular flow of atomization air around a fluid discharge orifice formed by a tubular portion on the fluid tip to aspirate fluid from the orifice and to atomize the fluid. The air cap also directs pattern shaping air at the atomized paint.  According to one feature of the invention, the spacing of the pattern shaping air orifices from the fluid discharge orifice is made sufficiently great that undue turbulence is not induced in the atomization air in the aspiration zone to maximize the fluid flow rate. According to a second feature of the invention; the fluid orifice in the fluid tip has a straight cylindrical portion and an expanding conical section connecting the cylindrical section to an annular flat front face of the tubular portion, of the fluid tip. The flat portion of the front face on the tubular portion is kept to a minimum to increase the particle distribution uniformity of the atomized paint.

Abstract: Abstract of the Disclosure Disclosed is a fiber amplifier including a gain fiber and a source of pump power having a wavelength .lambda.p coupled to one end thereof.  A signal of wavelength .lambda.s is introduced into a first end of the gain fiber,  and an amplified signal of wavelength .lambda.s is coupled from the second end thereof.  The signal can traverse an undesired secondary path as well as a preferred primary path to the amplifier output.  To prevent light of wavelength .lambda.s from traversing the secondary path and thus increasing the amplifier noise figure, the amplifier includes attenuating fiber means for attenuating that portion of  the  signal  of  wavelength  .lambda.s that  propagates  in  the secondary path.

Title: Method and device for automatic synchronisation of data bursts
Inventor: MARTINEZ GARCIA FRANCISCO J
IPC: H04W56/00
Filed: 1994-11-18
Abstract: SUMMARY            Method and device for automatic synchronisation of data bursts.      Applicable to cordless communications systems with time division multiple access, TDMA, for synchronising the timebases of cordless terminals and base stations. This device, which receives periodically and for a short interval of time a burst reception signal (A) to be synchronised, incorporates a register (1) which stores the value of a counter (3) when the burst reception signal (A) is high and subtracts from it, in an adder circuit (2), a reference value (REF) in order to adjust the references between the two timebases. To the output value (DELTA), a maximum value (MAX) is added or subtracted in a second adder circuit (4), depending on what timebare, the internal or the reference one is faster. Its output is compared with that of the counter (3) in a comparator (5) and the output (T) from the comparator is applied to a control circuit (6) that determines the module in the counter (3) for lengthening or shortening the burst to achieve synchronism.

Title: Qam signal encoding/decoding system
Inventor: GUIDA ALLAN A
IPC: H03M13/25
Filed: 1993-05-11
Abstract: An encoding scheme resistant to transmission errors encodes a data bitstream for application to a quadrature amplitude modulator (QAM) in a high definition television system. The error-resistant code provides a rotationally symmetrical 32-point constellation on a plane defined by I, Q quadrature axes. The constellation is divided into first (A) and second (B) partitions ar-ranged so that constellation points that are closest in distance to any constellation point of the first partition belong to the second partition, and constellation points that are closest in distance to any constellation point of the second partition belong to the first partition. The binary value of one bit of each of successive 9-bit packets in the bitstream determines that one of the two partitions (A, B) to which both of a consecutive pair of first and second constellation-point transmissions belong (the first and second trans-mitted constellation-points of that consecutive pair being selected by the then current 9-bit packet of the stream). The code is such that the binary values of such one bit of each of alternate ones of the successive 9-bit packets are opposite to one another. This permits a receiver decoder to decide whether each received constellation-point belongs to a first or a second constellation, thereby permitting the detection and, in most cases, the correction of transmission errors.

Abstract: A unitary, insulated panel is provided for use in sectional doors and walls. The panel comprises opposed, spaced apart, parallel, inner and outer metal skins. The skins are mechanically interlocked along their top and bottom ends byintegral, inwardly projecting flanges having mutually engaged, hook-shaped terminal portions. The opposed flanges at each end are coplanar. The engaged hook-shaped terminal portions combine to form a longitudinally extending slot. The mouth of the slot is narrow relative to its bulbous inner portion. A strip of weather seal can be inserted longitudinally into the slot, for sealing purposes. Foamed polyurethane is formed in situ in the space between the skins. The polyurethane bonds to the skins. A rigid, strong panel unit is obtained by the combination ofmechanically interlocking the skins and bonding them with the core.

Abstract: Proteinaceous gas- or gas precursor-containing microbubble contrast agents, e.g. for use in ultrasound and/or MR imag-ing, in which the protein matrix is crosslinked by reaction with a bifunctional aldehyde (e.g. a dialdehyde such as glutaraldehyde or an .alpha.,.beta.-unsaturated aldehyde such as acrolein) in an aqueous medium at substantially neutral pH exhibit improved in vivo and storage stabilities, particularly if the matrix is also reacted with a Schiff's base reducing agent such as a borohydride. Modifica-tion of the size distribution of such crosslinked proteinaceous gas-containing contrast agents, e.g. to reduce the mean size of the microbubbles, further enhances their stability and permits preparation of novel contrast agents having a particularly narrow mic-robubble size distribution.
