Title: Scintillation counter for beta and gamma radiation - is large phosphorus crystal with lined recess for sample vessel
IPC: G01T1/204
Filed: 1975-07-01
Abstract: A scintillation device comprises a scintillating counting chamber of inorganic phosphorus in crystalline from; the scintillation block is elongated and has a depression to receive a sample vessel; this depression is lined with a highly transparent substance, the refractive index of the phosphorus, of the lining and of the sampling vessel being all approximately the same; the lining is highly transparent and has a low photon absorption capability of less than 20% for wave-lengths in the range 3500-4200 angstroms and completely seals the phosphorus surface adjacent to it. The sample vessel fits neatly into this lining and is also of highly transparent material; a seal couples together the three surfaces and also has a similar refractive index. The entire surface of the phosphorus is coated with a material which reflects photons in wave-lengths of the same range as above, so that photons generated in the sample are transmitted into the crystal and are not emitted from it. The inorganic phosphorus and the photodector surface is surrounded by a metal housing having a door for insertion of the sample flask; an electronic circuit receives and summates pulse signals from the photodetector and amplifies the summated signals to give a predetermined amplitude difference and to analyse the signal.

Title: Noise suppression circuit for video signal - separates signal into high and low frequency components and has delay circuit with time delay when switched over
IPC: H04N5/21
Filed: 1981-02-18
Abstract: In the circuit a video signal is separated into its high and low frequency components by a separating circuit (3). The signal at an output (15) of a delay circuit (17) is combined with the separated low frequency signal in a combining circuit (11) whose output is applied to the input (19) of the delay circuit. The time delay of this circuit is switched from field to field by means of a change-over switch (53) so that this time delay changes from field-to-field to a field period minus and a field period plus half a line period. The noise-suppressed low frequency output from the combining circuit (11) is added to the separated high frequency component in an adder circuit (25). In use such a noise suppression circuit produces no travelling noise patterns on a television display.

Patent NL-8902406-A (NL)
IPC: G01N33/86
Filed: 1989-09-27
Abstract: A method for determining the endogenous thrombin potential (ETP). which shows how much and for what length of time thrombin has been active in a sample of clotting blood or plasma. The ETP can be used for determining the effectiveness of treatment with antithrombotics of any type. Said ETP determination comprises adding to said sample a thrombin substrate, an activator of thrombin formation, a preparation of proteaseinhibitor and if desired a pharmaceutical for analysis . The thrombin substrate is preferably selected to not completely consume the amount of thrombin generated in the sample, to have a rate of conversion of the substrate which is proportional to the amount of thrombin present and to have a measurable conversion product resulting from the conversion by thrombin. Determination of the amount of conversion product leads to determination of the ETP. The choice of activator determines whether the effect is measured on the intrinsic or extrinsic clotting system, making it possible to determine the effect of the pharmaceutical, which is being analysed, on various parts of the clotting mechanism.

Title: Coin and token handling system for gambling machine - determines validity and value of transparent tokens by scanning bar codes embedded in tokens
IPC: G07F17/32
Filed: 1990-05-04
Abstract: The machine validates coins, which may be normal currency or tokens, after they have been inserted (1). The coins are then diverted into a collection box, into a payout stack or, in the case of unvalidated tokens, back to the user. After validation (2), the coins may be diverted by a flap valve (3) straight to a collection box (5), from which the machine owner may remove them, or along an incline to a scanner (6) which reads the bar code to determine the token's worth. Invalid tokens are diverted via a second flap valve (7) and tube (10) to the pay out chute (11). Valid tokens are stacked in another tube (8), ready for payout. When the payout tube (8) is full, the excess tokens overflow (9) into the collection box. @(9pp Dwg.No.1/3)@.

Title: Method for laying a suspended floor on a resilient underlayer
IPC: E04F15/18
Filed: 1993-05-21
Abstract: The invention relates to a method for laying a suspended floor on a resilient underlayer. The main requirement this has to meet is the absence of visible seams. These mainly result from the expansion and/or shrinking of the underlayer on which a suspended floor is laid, in connection with the ambient temperature and relative humidity, which greatly affects the extent to which the floor consisting of sections is fixed with respect to the underlayer. Surprisingly, this existing problem is found to be solved by making use of a resilient underlayer, e.g. a foam underlayer. The most favourable solution is effected by first stretching the underlayer in one or more directions, then applying a layer of adhesive to this and then fixing the floor sections to said biased (prestressed) underlayer. The bias (prestress) on the underlayer prevents subsequent formation of seams and therefore solves the existing problem. <IMAGE>

IPC: C07K14/575
Filed: 1986-02-21
Abstract: GnRH peptide analogs which regulate the secretion of gonadotropins by the pituitary gland and either promote or inhibit the release of steroids by the gonads. Administration of an effective amount of a GnRH antagonist prevents ovulation of female mammalian eggs and/or the release of gonadotropins. Administration of GnRH agonists can be used to regulate fertility in male and female mammals.These and other peptide hormones exhibit improved binding efficiency and biological potency as a result having a residue in a critical, generally central location in the chain which residue contains a mixed alkyl ketone side-chain terminating in an aromatic group. Methods for efficiently synthesizing these peptides from readily available compounds are disclosed.
