Title: Controlling temperature by passing fluid through a translucent transparent panel
Inventor: CARR MICHAEL DAVID
IPC: F24J2/40
Filed: 1993-05-10
Abstract: A method and apparatus for controlling the temperature of (e.g. cooling and/or shading) an area is described. A hollow, translucent or transparent panel 10 is mounted adjacent the area and fluid is passed through it a rate proportional to the degree of temperature control required. The fluid may be heated and/or cooled; it may be transparent, translucent or opaque; it may be coloured. The panel may be flat or curved and has in it a plurality of fluid tight passageways (generally linear or sinuous) coupled to fluid supply means 26 energisable responsive to the temperature on one side of the panel. Enclosures (figures 4 and 5) are described formed of a number of similar panels mounted in a framework, which enclosures comprise permanent or temporary buildings or other structures, or temporary extensions for buildings or vehicles. The framework may be used to pass the fluid to/from the panels.

Title: Withdrawing stacks from a continuous stacking location
Inventor: KLENK RAINER
IPC: B41F13/70
Filed: 1993-05-19
Abstract: After a stack of sheets 5 delivered at 4 has built up on a lowering pallet (not shown), a flexible belt 21 is moved across the face of the stack so that a lateral extension 21a of the belt, initially clear of the stack, is introduced between sheets 5 across the whole width of the stack face. Continued lowering of the pallet forms a gap beneath extension 21a and an auxiliary stack holder 15 is moved along guideway 16 into the gap. Extension 21a is withdrawn from the stack, holder 15 is lowered as an auxiliary stack builds up, the main stack and its pallet are removed, a fresh pallet is raised to receive the auxiliary stack and holder 15 is moved back along guideway 16 and then raised to its initial position. Holder 15 incorporates air nozzles 15a, 15c. <IMAGE>

Title: Headgear communications without earphones
Inventor: BURDEN PETER
IPC: A42B3/30
Filed: 1994-11-18
Abstract: An audio vibrator 2, 4 is attached to a rigid part of the headgear, which part then transfers the vibrations to the test of the headgear. The rigid parts produce audible sound for the ears, whilst those parts in contact with the skull can transmit vibrations via the bone structure, direct to the inner ears.

Patent GB-2290635-A (GB)
Title: Active control of noise and vibration
Inventor: SOUTHWARD STEVE C
IPC: G05D19/02
Filed: 1995-06-07
Abstract: An active system for controlling vibration or sound limits the output gain G from a gradient descent algorithm, such as an LMS algorithm, according to the relationship   <IMAGE> and reduces one of first and second filter weights W1 and W0 such that G </= Gmax ensuring the output cancelling signal is never saturated. This eliminates the square wave shape which may impart unwanted harmonics or resonances to the dynamic system. In another aspect, the system eliminates drift of the output device toward saturation when situations are encountered such as singularities in the quadratic performance surface. This is accomplished by applying leakage factor r(k) to a function f(k) at or near a predetermined limit to avoid saturation of the output device. The function f(k) can be the gain G or the weights W(k). Another aspect is to provide a constant, optimum, and stable adaptation rate in an LMS system by providing an optimum adaptation coefficient  mu opt that provides a constant, uniform, and optimum adaptation rate on a per period basis for all frequencies. Various combinations of the above are described and are useful in active control systems. <IMAGE>

Title: Pump
Inventor: TSUI WILLIAM TAK MING
IPC: F04D3/00
Filed: 1996-06-27
Abstract: A pump has a bearing stand (3) in which a pump shaft (1) is mounted to be, driven by an electric motor. The shaft (1) mounts an impeller (9) having blades (10) which cause fluid entering through an axial inlet nozzle (11) to flow by rotation of the impeller in one direction. A centrifugal exit nozzle (12) is formed by a suitably located quarter toroid (13), and a half torus (14), formed as sheet metal pressings. When the impeller is rotated in the opposite direction the nozzle (12) acts as an entry nozzle and the nozzle (11) acts as an axial discharge. The pump is particularly suitable for treating textile yarns since said one direction of rotation can be used for out to in treatment liquor flow where relatively high resistance is encountered and said opposite direction of rotation can be used for in to out treatment liquor flow where resistance is relatively lower.

Title: Wellhead fluid connector with check valve
Inventor: GARIEPY JAMES A
IPC: E21B33/04
Filed: 1996-10-28
Abstract: A tubular wellhead member (not shown) has an inner seal surface. A hydraulic passage extends through the wellhead member and terminates at a port at the seal surface. A tubing hanger 23 having an outer mating surface lands in the wellhead member. A hydraulic line extends from a hydraulically operated downhole safety valve to a passage 43 in the tubing hanger 23 and terminates at a tubing hanger port 44. A seal 53 is located at the tubing hanger port for sealing the junction with the tubular member port. A check valve 63 is located within the seal 53 to maintain the tubing hanger fluid passage 43 closed until the tubing hanger lands in the wellhead. An adapter 77 is employed to apply a running-in hydraulic fluid pressure to the tubing hanger hydraulic fluid passage 43 with the check valve 63 open. Then, the adapter 77 closes the check valve 63 to trap hydraulic fluid pressure in the line leading to the downhole safety valve. This pressure is sufficient to maintain the downhole safety valve in an open position during running in.
