Title: Power supply unit for overload relay
Inventor: REEDER BRIAN MARTIN
IPC: H01H71/12
Filed: 2008-08-04
Abstract: An overload relay 101 for protecting a motor or other device from an overload condition and a power supply unit 160 for supplying power to the overload relay. The overload relay comprises a plurality of shunt resistors 110a, 110b, 110c, each shunt resistor being locatable in the current path of a respective supply line of a power supply for the motor or other device; and a control means 120 connected to each of the shunt resistors and arranged to receive signals representative of current through each of the shunt resistors. The control means is arranged to produce a trip signal to interrupt the continuity of the power supply if it determines that an overload condition exists based on one or more of the signals representative of current through the shunt resistors. The power supply unit comprises a rectifier 162 for producing a direct current from one or more supply lines of an AC power supply connected to a motor or other device protected by the overload relay, and at least one transformer 168a, 168b, 168c, for coupling the power supply unit to the overload relay.

Title: Using time domain reflectometry signatures to identify connection changes and/or line faults in patch panels
Inventor: MACAULEY DANIEL WARREN
IPC: H04L12/26
Filed: 2008-12-22
Abstract: Methods, systems and computer program products for uniquely identifying communication lines in a network via time domain reflectometry (TDR) signatures are provided. A pulsed signal is sent into a communication line through a patch panel connector port and a reflection of the pulsed signal through the patch panel connector port is received to obtain a TDR signature for each communication line. The pulsed signal is sent and received by a controller operatively associated with the patch panel and/or by a network switch in communication with the patch panel. Connection changes and/or communication line faults at a network patch panel are detected by comparing current and stored TDR signatures.

Abstract: 289,048. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). April 22, 1927, [Convention date]. High-potential switches; contacts. - In order to ensure the disengagement of the knife blade of outdoor switches from the fixed clip if additional friction eaused, for example, by freezing up is present, a loosening force is applied in the initial portion of the blade movement. As shown in Fig. 1 at the end d of the blade c is pivoted a bell crank e carrying at its free end a roller which bears on a horizontal runway. The crank e is pivoted to a rod moving in a guideway m, the rod f being connected by a link k to a crank arm i on a rod mounted at the end of an insulator g rotated by the operating shaft h. During the initial portion of the opening movement the bellcrank e is rotated and the pressure produced between the roller at its free end and the horizontal guideway forces the blade c out of the contact clips so that when the crank e is brought against a stop l the blade c is free to rotate to its open position. In the modified form (Fig. 2, not shown) the member c is in the form of a hollow tube which has mounted within an auxiliary blade adapted to be released from its cooperating contact. clip in a manner similar to that already described.

Title: Improvements in and relating to the production of boron compounds
Inventor: TAYLER FREDERICK MAURICE
IPC: C07F5/00
Filed: 1958-03-31
Abstract: Amine boranes are produced by reacting sodium or potassium borohydride in aqueous solution with a salt of a primary or secondary amine or of a heterocyclic nitrogen base in which at least one basic nitrogen atom is present as a member of a heterocyclic ring system, all three normal valencies of any such nitrogen atom being satisfied by its neighbours in the heterocycling ring system.  Suitable amines are mono- and dimethyl amine and their higher homologues, allylamine, ethanolamine, morpholine, piperazine or piperidine, quinoline, quinaldine, isoquinoline, acridine and hexamine.  The acid component of the salt may be a mineral acid, e.g. hydrochloric or sulphonic acid, or an organic acid such as acetic acid.  The process may be effected at 0 DEG  to 100 DEG C.  It is preferred that the amineborane is continuously removed as it is formed, as by extraction with a solvent which is inert and incompletely miscible with water, e.g. an ether or hydrocarbon.  A buffering agent, e.g. potassium monohydrogen phosphate or a slight excess of borohydride may be used to maintain neutral or alkaline conditions.  The folowing amine boranes are novel: monoisobutylamine borane, mono-isopropylamine borane, allylamine borane, laurylamine borane, hexamine borane, di-n-propylamine borane, di-isopropylamine borane, isoquinoline borane, quinaldine borane, acridine borane, and piperazine borane. Reference has been directed by the Comptroller to Specification 822,229.

[Class 38 (v).] In a rotary switch of the kind in which the contacts of the clip and blade type are arranged in superimposed compartments, one arm of each clip is of thin springy metal while the co-operating arm is of rigid metal of greater mass and thermal capacity and of greater peripheral extent so that contact is made and broken at the rigid contact which is better able to absorb and dissipate the heat formed on arcing. In the form shown, the blade contacts 1 are stationary while the bridging contact clips 2 are mounted on an operating spindle. Each clip consists of a rigid sectorshaped bridge member having contact surfaces 4, 5 and a springy member with contact surfaces 6, 7. These are mounted in pairs on an insulating bush to co-operate with a blade contact. As shown in Figs. 2 and 3, the rigid contacts are of greater extent and so overlap the springy, contacts.

[Also in Divisions D1] In the event of breakage of the yarn on a circular knitting machine the electric motor driving the needle cylinder 13 is automatically stopped by reverse current braking, applied for a predetermined time. Yarn breakage allows needle latches 11A to fly out and they are then contacted by a probe 9 and thereby complete a circuit between the anode and trigger of a thyristor D2, thus switching it on to energize a relay E1 Contacts E1A interrupt the motor supply and contacts E1B trigger a timing circuit comprising transistors T1 . . . T3, which energizes a second relay E2 for a time determined by RC circuit R8, R9, C4. Relay contacts 31 apply reverse current to the motor and 33 control an indicator lamp L. The device is reset by push 19 which opens the thyristor circuit. The components may be mounted on a plug-in printed circuit board. It is mentioned that the thyristor circuit may be replaced by a multivibrator and the relays by electronic devices.

Abstract: 892,013. Optical gauging-apparatus. BRITISH IRON & STEEL RESEARCH ASSOCIATION. March 31, 1958 [April 1, 1957], No. 10553/57. Class 106 (2). [Also in Group XX] A method of measuring a dimension of a moving object 6 at successive points along the axis of movement comprises directing the optical axis of an object-side telecentric lens system 1, 4 perpendicularly to the axis of movement of the object to provide an image 5 of the object and gauging the dimension of the object from the image. By using an objectside telecentric system the size of the image is unaffected by variations in the distance of the object from the lens system. Fig. 5 shows an embodiment in which images of opposite sides of the object 6 are formed in a single telecentric system 10 by pentagonal prisms 14 and mirrors 11, 12. By adjusting the positions of one or both prisms, or the mirrors, selected parts of the two images can be made to coincide. The adjustment required is a measure of the diameter of the object 6. In other embodiments described, Figs. 2, 4 and 9 (not shown), measurements are made in two perpendicular sections, in three sections spaced at small angles, and in a number of angularly spaced sections. A description is also given of a method of measuring the cross-section of an object by rotating the object about its axis of movement relatively to the lens system and producing a composite image photographically or on a television screen.
