Title: Active armour protection system for armoured vehicles
Inventor: LLOYD PETER G
IPC: F41H7/04
Filed: 1990-10-05
Granted: 2006-10-12
Abstract: A sensor system for defending armoured vehicles against projectiles through the use of active armour.      A thermal sensor detects a projectile's presence, and a laser proximity sensor determines its location. A doppler sensor distinguishes between threatening and nonthreatening projectiles by measuring the projectile's velocity. The sensors are positioned in a housing with a segmented spherical window, wherein each sensor can detect the projectile through a window segment having a filtering characteristic which is matched to its associated sensor. An eyelid shutter, which can open and close, protects the window from small arms fire and shrapnel. A conical deflector protects the sensor system from objects such as tree branches. Heater elements are used to clear ice and snow from the window, and the eyelid shutter removes other material through the use of a cleaning liquid delivery system and rubber wipers.

Title: Compensation of static and/or quasi-static magnetic fields in magnetoelastic force and torque transducers
Inventor: HOFFMAN BERTIL
IPC: G01L1/12
Filed: 1990-12-18
Granted: 1999-04-27
Abstract: If the B-field of a body with a sinusoidal symmetrical magnetization exhibits even harmonics, this means that the body also has a superimposed static and/or quasi-static magnetization.  The invention comprises a method and a device for determining and measuring, respectively, the content of even harmonics (8).  The content corresponds to the degree of static and/or quasi-static magnetization and is used as input signal to a regulator (11) which, with the aid of a direct current in, for example, a separate winding (14), reduces the static and/or quasi-static magnetization to zero.

Filed: 1991-04-29
Granted: 2000-03-21
Abstract: A periodic pulse discrimination system (10) particularly suitable for use with electronic article surveillance systems is capable of detecting valid tag pulses while discriminating against periodic pulses caused by resonances and interfering carriers as well as random noise. Circuitry that determines the periodicity of a pulse signal and is responsive to amplitude differences between successive detected pulses controls an adaptive threshold and sampling window (30) to discriminate against signals having an incorrect periodicity and an inadequate envelope rise time. A notch circuit (42) notches out pulse trains that have the correct or substantially correct periodicity but persist for a longer time period than the time period required for a tag to pass through the detection zone.

Title: Acupuncture needle container and insertion tube
Inventor: CHOI JEUNG HO
IPC: A61H39/08
Filed: 1992-07-13
Granted: 1997-03-04
Abstract: A combination container and dispenser and insertion tube for acupuncture needles provides for the sterile storage and contain-ment, dispensing and insertion of acupuncture needles.  A storage portion  of the container/dispenser is formed with  an  insertion tube  along  one  edge and an internal passage  between  the  two components.  A slot in the storage portion allows manipulation of the  handles  of any acupuncture needles within so  they  may  be transferred  through the internal passage to the  insertion  tube and  inserted  into the patient.  A series of depressions  and  a retaining  crest within the storage portion assist  in  retaining the  needles  in position until they are maneuvered  through  the slot.   The  device  may be formed of  a  relatively  inexpensive material,  thus  allowing  for disposal after a  single  use,  or alternatively may be formed of a more durable material capable of withstanding  repeated sterilization in an autoclave  or  similar apparatus for reuse.

Title: Methode et dispositif pour le filtrage du plasma
Inventor: KAWAMURA AKIO
IPC: C07D213/65
Filed: 1992-03-24
Granted: 1999-08-31
Abstract: Procédé de filtration du plasma destiné à séparer le plasma sanguin des globules à l'aide d'un premier filtre et à enlever les substances de masse moléculaire élevée qui constituent des composants nocifs dudit plasma par filtration dudit plasma à l'aide d'un second filtre. Selon ce procédé deux opérations sont effectuées: une opération consistant à ouvrir la chambre intérieure du second filtre à l'atmosphère pour abaisser la pression chaque fois qu'une valeur limite d'augmentation de pression est détectée, augmentation due à une tendance à l'obstruction dans ledit filtre, et une opération consistant à nettoyer ledit second filtre à partir des côtés des chambres intérieure et extérieure après que la pression a été abaissée dans la chambre intérieure. Ainsi une perte de plasma dûe à la décharge dudit plasma vers l'extérieur du système pendant l'opération de désobstruction du second filtre peut être réduite.

Abstract: A device comprises cleaning heads 4,5 mounted on a shaft 1 for free rotation. On sinking and elevating the device on a tractive member 10, in a liquid up-current, the heads 4,5 start rotating in in different sides. Cutting elements - knives 6 having an involute profile and arranged on oppositely directed spiral paths cut the deposits. On descent, cutting collars 14 of said knives 6 situated in the lower portion on head 5 perform "rough" cutting, the knives 6 of both heads 4,5 crush the cuts and chip, and cutting collars 13 in the upper portion of the upper head 4 carry out the "finishing" of the internal surface of an elevating stiring. The given mathematical relations defining the ratio of parameters of the device elements are as follows: the heights of heads 4, 5 and an angle of attack of knives 6, the lengths of the shaft 1 and a stabilizer 8, their mass, the length of the pitch of knives 6 and the diameter of the heads 4,5.

Abstract: A joint between an upper wall part and a lower wall part of a modular tub/shower unit includes a recessed band adjacent to but spaced from the lowermost edge of the upper wall part. A further band is recessed at the uppermost edge of the lower wall part with the vertical height of that band being greater than the vertical height of the recessed band in the upper wall part and greater than a band at the lowermost edge which is not recessed. The lowermost band of the upper wall part is then adhesively attached to the uppermost edge and a part of the recessed band of the part by a double sided adhesive tape the covering of which is pulled through the gap between these parts. The adhesive tape provides the only sealant necessary for waterproofing the joint and provides the only structural strength necessary. The groove above the lowermost band of the upper wall part allows the upper wall part to be maneuvered into the required position by finger engagement into the groove. The recessed bands adjacent the upper and lower edges of the parts provide stiffening strength.

Granted: 1999-03-23
Abstract: A compensator for thermal or other uncontrollable effects in a liquid-crystal etalon filter (10). The narrow pass band of the filter is controlled by adjusting the amplitude (48) of an AC drive signal (44, 46) applied to the electrodes (22, 24) on either side of the liquid crystal (26) in the filter. An optical detector (36) detects the intensity of light (30) from a narrow-bandwidth input beam (34) passed by the detector. Electrical circuitry (40) determines the bipolar amplitude of the component of the light intensity that is at twice the frequency of the AC drive signal (the doubled-frequency amplitude) and adjusts the amplitude (48) of the AC drive signal in response to the doubled-frequency amplitude so as to reduce the doubled-frequency amplitude toward zero.
