Title: Nonwoven and film corrugated laminates.
Inventor: ZELAZOSKI GREGORY ALAN
IPC: B32B3/28
Filed: 1996-06-21
Abstract: The present invention is directed to corrugated laminates with density differentials created in at least one of the layers of the laminate. The laminates (10) include a first layer (12) bonded to a second layer (14) to form a composite which has a plurality of corrugations forming a series of peaks separated by a series of valleys. At least the second layer is formed from a compressible material such as a fibrous nonwoven web which has formed therein areas of different density due to the formation process used to form the laminate. In one process the first and second layers are bonded to one another along a series of generally parallel bond lines (16) while at least one of the materials is in a tensioned state. Once bonding is completed, the tension is released and the laminate forms a series of corrugations. In the valley areas (18) immediately adjacent the bond lines the laminate and in particular the second layer has an increased density due to the bonding process. In the peak areas (20), which are between the valley areas, the laminate and in particuar the second layer has a lower density. As a result, fluids entering the laminate through the first layer tend to be drawn toward the more dense areas adjacent the bond lines. This couples with the reduced surface contact area of the first layer due to the corrugations, tend to make the material particularly well-suited for use as a body side liner for personal care absorbent articles.

Title: Interference reduction in shared-frequency wireless communication systems.
Inventor: ARNOLD HAMILTON WEBSTER
IPC: H04B7/26
Filed: 1998-07-15
Abstract: An apparatus and method for reducing interference between an uplink transmitter of a fixed satellite service (FSS) system (150) and an uplink or downlink receiver of a local multipoint distribution service (LMDS) system (100) are described. An ordered list of the preferred uplink transmission frequencies is assigned to all FSS uplinks located in a particular cell of the LMDS system (100). Different ordered lists are used in different cells (105-1 - 105-3) of the LMDS system (100), while uplinks located in the same cell can utilize the same order list. Further, the ordered list may be selected by the LMDS service provider such that the impact of interference from FSS uplinks can be readily predicted and minimized. Therefore, the system allows simultaneous access to a shared frequency band for both LMDS and FSS systems (100 and 150).

Title: Method and apparatus for measuring a parameter of a lithographic process, substrate and patterning devices for use in the method
Inventor: MAURITS VAN DER SCHAAR
IPC: G03F7/20
Filed: 2016-08-09
Abstract: A substrate has first and second target structures formed thereon by a lithographic process, lithographic process comprising at least two lithographic steps. Each target structure has two-dimensional periodic structure formed in a single material layer, wherein, in the first target structure, features defined in the second lithographic step are displaced relative to features defined in the first lithographic step by a first bias amount, and, in the second target structure, features defined in the second lithographic step are displaced relative to features defined in the first lithographic step by a second bias amount. An angle-resolved scatter spectrum of the first target structure and an angle-resolved scatter spectrum of the second target structure is obtained, and a measurement of a parameter of a lithographic process is derived from the measurements using asymmetry found in the scatter spectra of the first and second target structures.

Title: Serum protein marker set and test kit for detecting advanced schistosomiasis
Inventor: HAIYONG HUA
IPC: G01N33/68
Filed: 2021-03-17
Abstract: The present disclosure discloses use of a serum protein marker set of prenylcysteine oxidase and apolipoprotein in the preparation of a test kit for distinguishing classic advanced schistosomiasis and newly-developed advanced schistosomiasis (NDAS). Isobaric tags for relative and absolute quantitation (iTRAQ) and multiple reaction monitoring (MRM) are used to identify and verify serum proteins in serums of classic advanced schistosomiasis patients, NDAS patients, and normal people, and it is found that the classic advanced schistosomiasis patients show a prenylcysteine oxidase expression level 2 to 3 times that in the NDAS patients and the NDAS patients show an apolipoprotein expression level 2 times that in the classic advanced schistosomiasis patients. The present disclosure also discloses a test kit for distinguishing classic advanced schistosomiasis and NDAS, including a polyclonal antibody (pAb) for prenylcysteine oxidase, a pAb for apolipoprotein, a loading buffer, and an ELISA 96- well plate. The test kit of the present disclosure can accurately distinguish classic advanced schistosomiasis and NDAS and has promising market prospects.

Title: Control circuit for electric motor of dental drill - uses semiconductors to produce three=phase current from DC source
IPC: H02P1/40
Filed: 1977-07-12
Abstract: The dental drill is driven by a three phase stator wound electric motor. The motor operates on a dc supply with an inverter consisting of several semi-conductors connected to certain of the motor phase windings and to a frequency variable signal pulse generator by a switching circuit. This circuit enables one pair of semi-conductors to be blocked whilst another pair becomes conducting. This in turn supplies a three-phase current to the motor to allow it to rotate in one direction at a speed proportional to the frequency of the signal pulse. A voltage regulator is also connected to the circuit and enables the dc voltage across the motor to be varied over a pre-determined range depending on the frequency of the signal pulse. The max. turning moment is obtained at the relatively low speed of 5000 r.p.m.

Title: Laboratory table with sunken gas and water connections - flanged plugged and sealed to give overall flush surface
IPC: B01L9/02
Filed: 1979-04-12
Abstract: Connections for gas and water are uniformly distributed over the surface of the leaf of a laboratory table, and are sunk in such a way that when a plug is inserted, the table has a near enough completely flat surface. Fittings are arranged so that the connections can be attached to feed lines below the table, and in place of the plug a means of controlled delivery such as a valve can be screwed in place. The upper end of the connection is cylindrical and is stepped down to suit a corresponding bore in the tablet so that when the connection is tightened down by means of a nut, its upper surface is flush. Each plug is a disk which screws into the connection and tightens down on to an "O"-ring. The inconvenience caused by one gas or water tap at a fixed point on the table surface, leading to the expense of fitting auxiliary connections, and the restrictions on the space for apparatus, etc. is eliminated.

Title: Photocopier costing calculator - has counter circuits to prevent user making small number of copies while being charged at lower rate appropriate to large number of copies
IPC: G03G21/02
Filed: 1981-09-07
Abstract: The photocopier has a copy control which is set by the user to the number required, and that number is used to address a memory, which adds an appropriate number of count pulses to the total for each copy. To prevent fraud, if the user programmes a large number of copies and stops the machine early in the cycle. The two counters are used. One counter is preset to the charge factor for a programmed cycle, and the other counts the charge per copy during the cycle. If the totals at the end of the cycle are identical, the first counter figure is added to the totaliser. If not, the difference between them is used to calculate a new factor appropriate to the number of copies.
