Abstract: The device for spraying a pulverulent lubricant or release agent dispersed in an air stream onto the pressing tools in a tableting press, comprises at least one spray nozzle 14 for applying the powder-containing air stream to the pressing tools, a suction system 16, 19, 20 for sucking the excess residues of lubricant off the pressing tools and a metering device 1, 2, 3, 4, 5, 6 having an air jet injector 3 for reproducibly loading the air stream with the lubricant. The essential step consists in the fact that the pressing tools 15a, 15b of the tableting press are connected to a sensor 21, which generates an output signal which is characteristic of the extent to which the lubricant is covering the surfaces of the pressing tools and controls the amount of air sucked off at the suction system 16, 19, 20 and/or the loading of the air stream with the powder. As a result it is possible to achieve a reliable and operationally safe lubrication of the punch surfaces in the tableting machine even when tableting critical products which tend to cake. Moreover, the operational reliability and the service life of the machine are improved.

Filed: 1996-08-29
Abstract: The present invention relates to the management of pain without requiring or allowing for reduction in the level of administration of narcotics, and to self-management of pain on an outpatient basis. Accordingly, the present invention is broadly directed to a method for treating pain in a subject comprising administering via a transmucosal, transdermal, or oral route a dose of ketamine effective to alleviate pain to a subject suffering from pain. The invention is further directed to a method for synergistically treating pain in a subject comprising administering via any route a dose of ketamine effective to allow for reduction in the level of an ongoing pain therapy, or decrease pain (improve the level of pain relief), or both. Transmucosal, transdermal, and oral administration of ketamine advantageously allows for patient self administration of the drug, which provides for pain management on an outpatient basis. Moreover, ketamine administration in transdermal devices (suppositories, candies, buccal patches) is generally socially acceptable. In a specific example, a patient suffering from intractable bladder pain controlled breakthrough pain by transmucosal (nasal) administration of about 16 mg to about 32 mg of ketamine per dose.

Title: Factor v ratio blood test for susceptibility to thromboembolism
Inventor: KU DEHUI WAYNE
IPC: C12Q1/56
Filed: 1996-11-29
Abstract: The disclosed Factor V Ratio (FVR) screening blood assay (read as "factor five ratio") and kits for the conduct thereof, identify individuals that possess a specific genetic defect, known as the Factor V Leiden defect, or other genetic or acquired Factor V defect, that makes those individuals susceptible to venous thromboembolism. In this test the Factor V activity of a blood plasma sample exposed to activated Protein C (APC) is compared to the Factor V activity of a similar sample in the absence of APC, after both samples had been treated with an activating agent. The ratio between the Factor V activity level without APC and the Factor V activity level with APC, identifies individuals at risk of a thrombotic disorder due to a Factor V defect and differentiates between individuals with a heterozygous defect and individuals with a homozygous defect.

Title: Digital tv receivers with poly-phase analog-to-digital conversion of baseband symbol coding
Inventor: LIMBERG ALLEN LEROY
IPC: H04N5/44
Filed: 1998-06-23
Abstract: A digital television signal receiver includes, instead of a single flash convert er as in the prior art, MN analog-to-digital converters of successive binary approximation type sampling baseband symbol coded signal on an MN-phase basis to provide a respective digital output signal, each of which sampling phases is of one-M th symbol time duration, M being a positive integer at least one and N bei ng a positive integer more than one. In a digital television signal receiver for ATSC standard signals, N is twelve. Equalization filtering is carried forward on an MN-phase basis, with output signals from N of the phases being supplied to N tre llis decoders as their respective input signals. Selecting M to be two facilitates sy mbol synchronization using first and second N-phase match filters for a prescribed pseudo-noise sequence in the data field synchronization codes. The first match f ilter responds to the digital output signals of the oddly ordinally numbered ones of t he 2N analog-to-digital converters as equalized by the 2N-phase equalization filter; a nd the second match filter responds to the digital output signals of the evenly ordinal ly numbered ones of the 2N analog-to-digital converters as equalized by the 2N-phas e equalization filter. A symbol synchronizer responds to differences in those matc h filter responses for adjusting the phase of sampling by the 2N analog-to-digital converters of successive binary approximation type.

Title: A clamp with clamping jaws and a carrier connecting them
Inventor: SCHUELE JOSEF
IPC: E04G17/04
Filed: 1997-07-11
Abstract: A clamp (1) serves for connecting form panels disposed in coplanar, side-by-side relation and for this purpose it engages their edge webs (2) or edge sections, which webs (2) can be directly adjacent to each other or have an intermediate piece inbetween. For adaptation to thereby varying spacings or for adaptation to different dimensions of edge webs (2) or edge sections, a first swivelling clamping jaw (4) is adapted to be adjusted steplessly relative to a stationary clamping jaw (5) and lengthwise of a carrier (6) presenting the two clamping jaws (4 and 5). In addition, the first swivelling clamping jaw (4) is swivel-mounted on a slide (10) which, in turn, can be fixed by jamming in any position on the carrier (6), particularly by a tipping or swivel movement in an opposite direction. Therefore the spacing between the clamping jaws (4 and 5) can be steplessly adjusted, without any measures for holding the swivel axis (9) of the swivelling clamping jaw (4) having to be taken on the carrier (6) itself, as would weaken the carrier (6).
