Title: Detection system for safety equipment
Inventor: SALISBURY RICHARD
IPC: F16P3/14
Filed: 1991-02-28
Abstract: A detection system for monitoring safety equipment being worn by an individual for whom the wearing of such equipment is mandatory. The detection system is more specifically directed to individuals who are passing through an entryway into a designated area which requires the wearing of the equipment, and also to operators of machinery which require the same. In one embodiment, the detection system includes an infrared reflector (22) which is fixed to a designated piece of equipment, for example, safety eyewear (20), an infrared transmitter (16) and an infrared receiver (18) which are located at one side of an entryway (12) to the designated area and an alarm system which is activated when a person who is not wearing the specified equipment attempts to pass through the entryway into the designated area. In another embodiment, the detection system includes a teleloop (152) mounted onto an entryway which emits an telemagnetic field (154), a signal generator which supplies the signal to the teleloop (152) at a pre-selected frequency, a ferromagnetic transducer (160) having a membrane (162) which is located on the safety equipment and vibrates when exposed to the telemagnetic field (154) to generate tone, and a sound receiver (158) which will receive the tone generated from the vibration of the transducer membrane (162). In this embodiment, an alarm is activated when no transducer produced tone is received by the sound receiver.

Abstract: A centralizer for downhole sucker rods such as those used in oil wells.  The centralizer has a central axial aperture for rotatable mounting on a downhole rod of a rod string.  The exterior surface of the centralizer is shaped to engage the well wall when brought into contact with the wall such that rotational movement of the centralizer is limited or stopped with respect to the wall.  Generally, the exterior of the centralizer is shaped to match the shape of the wall of the well in which it is to be used.  A centralizer for use with a well lined with a circular tubing thus has at least one exterior surface which in cross section defines an arc having a radius of curvature equal to that of the tubing interior.  A disclosed embodiment has six lobes having surfaces defining in cross section portions of three such arcs arranged symmetrically about the central aperture.

Abstract: On décrit un procédé pour réduire la tendance à l'agglomération des hydrates au sein d'un fluide comprenant au moins de l'eau et des hydrocarbures, susceptibles de former des hydrates, dans des conditions où ces hydrates peuvent se former, caractérisé en ce qu'on incorpore audit fluide un polymère ou copolymère hydrosoluble à base d'oxyde d'alkylène contenant au moins une séquence -(OR)-n dans laquelle R représente un groupement hydrocarboné de 2 ou 3 atomes de carbone et n représente le degré moyen de polymérisation de ladite séquence, au moins une des séquences -(OR)-n étant une séquence polyoxyde d'éthylène, en association avec un inhibiteur thermodynamique de formation des hydrates, par exemple un alcool ou un glycol. Ce procédé est particulièrement adapté au cas où le fluide à traiter contient une forte proportion d'eau, par exemple plus de 30% en masse. La présence de sels dans l'eau peut dispenser au moins partiellement de l'addition d'alcools ou de glycols. Les polymères et copolymères mis en jeu sont plus particulièrement des polyéthylèneglycols, des copolymères séquencés d'oxyde d'éthylène et d'oxyde de propylène, par exemple obtenus par condensation d'oxyde d'éthylène sur un polypropylèneglycol, ou par condensation d'oxyde de propylène sur de l'éthylène diamine suivie de la condensation d'oxyde d'éthylène. Les inhibiteurs thermodynamiques de formation des hydrates sont des alcools tels que le méthanol, le mono-, le di- ou le triéthylèneglycol, ou un ou plusieurs sels contenus dans l'eau de mer ou de gisement et notamment le chlorure de sodium.

Abstract: A detector for detecting changes in the output level of an amplifier included in, for example, a mobile communication system. A first detecting circuit produces a detected voltage having linearity with respect to low output levels of the amplifier. A second detecting circuit produces a detected voltage which is linear with respect to high output levels of the amplifier. The detected voltages from the first and second detecting circuits are mixed by a mixer in a predetermined ratio. When the output level of the amplifier changes over a broad dynamic range, the detector detects the changes with accuracy.

Title: Electronic system and method for monitoring abusers for compliance with a protective order
Inventor: CARROLL GARY T
IPC: G08B21/22
Filed: 1992-06-26
Abstract: An electronic monitoring system (10) monitors an abuser (12) for compliance with a protective order. When a violation is detected, the system automatically gathers evidence, independent of any that may be provided by a victim (24) of the abuser, to establish probable cause of such violation. The monitoring system includes a transmitter tag (14) worn by the abuser (12) that transmits a unique identifying (ID) signal (16), either periodically or when triggered. A receiving/monitoring device (RMD) (20) is carried by or positioned near the victim (24), e.g. in the victim's house (22) and/or place of employment, for receiving the ID signal. A  central monitoring computer (34) is located at a central monitoring location (36) that is in selective telecommunicative contact with the RMD. The computer maintains a response file that provides appropriate instructions to personnel or equipment at the central monitoring location or elsewhere in the event an abuser is detected by the victim's RMD.
