Title: Temporary wet strength polymers from oxidized reaction product of polyhydroxy polymer and 1,2-disubstituted carboxylic alkene.
Inventor: SMITH DAVID JAY
IPC: D21H21/20
Filed: 1997-03-25
Abstract: A temporary wet strength polymer and compositions for paper products, e.g., toilet tissue, is disclosed. The temporary wet strength polymer is the oxidation product of an esterified polyhydroxy polymer, more preferably of an esterified polysaccharide. The esterified polymer compound is formed by reacting the polyhydroxy polymer with a 1,2-disubstituted alkene compound that has at least one carboxylic acid group. The temporary wet strength polymer provides paper products having an initial wet strength that enables use of the product in the moistened condition, along with a suitable wet strength decay rate.
Patent CH-642511-B (CH)
Inventor: HARUYOSHI YAMADA
IPC: G04B33/10
Filed: 1979-11-16
Abstract: The fifth or intermediate wheel and pinion assembly of a gear train cooperates directly with the motor rotor pinion and the fourth wheel to provide a full stepdown in angular rotation between the motor rotor and a second hand. The upper tenon of the fourth wheel and pinion is supported on a third wheel bridge, and the upper tenon of the fifth wheel and pinion is supported on a fifth wheel bridge with the fifth wheel overlapping the tenon of the fourth wheel and pinion. This overlapping and elimination of wheels provides a compact, reliable and durable gear train for a timepiece of reduced dimensions.

Title: A packet scheduler and method
Inventor: HILL STEPHEN
IPC: H04B7/005
Filed: 2000-03-31
Granted: 2004-01-07
Abstract: In a CDMA cellular communication network, packet data may be broadcast at a discontinuous rate using a packet scheduler 7 which utilises available communication resources in each cell more efficiently than for continuous transmission. To maintain quality of service requirements, each packet scheduler is associated a power bin (9,10,11) which represents the total power available for transmission and reception in the cell. The maximum power level for each power bin may be adjusted in dependence of the quality of service experienced in each cell. A cell experiencing high levels of traffic may have its power bin increased to maintain acceptable carrier to interference levels at mobile stations 4,5, this is achieved by reducing the power bins of neighbouring cells which reduces intercell interference. Cell power levels are calculated using a genetic algorithm.

Title: Method and apparatus for detection of trace volatiles
Inventor: WAREHAM PETER DARREN
IPC: G01N33/46
Filed: 2003-04-30
Granted: 2007-02-21
Abstract: A method and apparatus for the detection of trace volatiles such as those produced by fungal decay of timber, comprising a sampling probe ( 10 ), comprising a housing ( 11 ) and bored barrel ( 12 ) adapted removably to receive an SPME device ( 14 ) in which a coated tipped fiber ( 15 ) is guided within a needle sheath ( 16 ) into the barrel ( 12 ), and a pump ( 19 ) is energized to draw a fluid sample over the fiber tip within the bore of the barrel. A motor ( 23 ) advances and retracts the SPME device ( 14 ) and its fiber ( 15 ) for a sample to be captured thereby and the captured sample is then released within an instrument having an array of gas sensors whereby any trace volatiles captured by and released from the coated fiber ( 15 ) may then be analyzed by computer software to produce a fingerprint for the location and identification of the presence of trace volatiles at a site into which the sampling probe is introduced. Thus, there is provided a robust device for the protective and easy introduction of an SPME fiber into a sampling environment where such devices conventionally could not be used.

Title: A storage unit with drawers
Inventor: PURDY PAUL DOUGLAS
IPC: E05B65/462
Filed: 2005-12-16
Granted: 2008-04-09
Abstract: A storage unit having a frame, drawers and a carrying handle. When the unit is lifted by the handle, or the handle is moved to a position suitable for lifting the storage unit, the handle arms lift the bottom drawer of the stack of drawers which in turn lifts each of the above drawers relative to the frame. As each drawer rises, the clearance gap between adjacent drawers is reduced and the drawers are moved to a locked position where they are blocked by detents mounted on the inside of the frame. In an alternative embodiment (not shown), the handle is coupled to drawer locking slides instead of the bottom drawer and detents on the drawer locking slides engage with the drawers to lock them in the closed position as the drawer locking slides are moved relative to the frame.

Abstract: PCT No. PCT/GB91/00073 Sec. 371 Date Sep. 9, 1992 Sec. 102(e) Date Sep. 9, 1992 PCT Filed Jan. 17, 1991 PCT Pub. No. WO91/11073 PCT Pub. Date Jul. 25, 1991.To alleviate problems experienced with field rate unconversion, a high definition source is field rate upconverted prior to bandwidth compression. Bandwidth compression is performed by a number of different methods, at least one of which is applied to the upconverted source signal. The branch or method of bandwidth compression transmission is selected in accordance with a control signal responsive to picture content. Prior to transmission of the upconverted bandwidth compressed signal, the signal is collapsed to the transmission field rate and the samples rearranged into a quincunxial configuration.
Patent GB-2251527-B (GB)
Title: Bandwidth reduction
Inventor: WESTON MARTIN
IPC: H04N7/12
Filed: 1991-11-18
Granted: 1994-05-04
Abstract: In a television system in which a signal of given bandwidth is to be transmitted over a channel of narrower bandwidth, the signal is subject to pre-filtering and subsampling at the transmitter and supersampling and post-filtering at the receiver. The post-filtering means (14) comprises three filters A, B and C in parallel which are selectable in response to the characteristics of the signal to be transmitted. In order to avoid anomalies caused by switching at the transmitter, the pre-filter (10) is a single filter with a fixed pass band equivalent to the union of the pass bands of the filters A, B and C of the post-filtering means (14). The pre-filter (10) thus effectively rejects signals of frequency, such that they would not be passed by any of the filters A, B and C.
