Title: Improvements in and relating to a dispenser for a roll of web material
Inventor: MARVELL ROBERT JOHN

Title: Electrical monitoring systems
Inventor: FRANK LOUIS MICHAEL
IPC: H05B1/02
Filed: 1984-02-13
Granted: 1987-12-23
Abstract: Electrical systems, especially elongate heating systems, include means for monitoring circuit continuity and/or absence of ground faults. The systems comprise a switching device, e.g. a thermostat, as well as a circuit breaker. When the switching device is on, a relatively high current passes through the circuit and when it is off, little or no current passes through the circuit. In one embodiment, a small controlled residual current flows in the circuit even when the switching device is off, and a current-detecting device signals when a discontinuity causes the current to drop below the expected value for the residual current. In another embodiment, the switching device is placed so that the heater (or other electrical load) is at a positive potential with respect to ground even when the switching device is off, and a ground fault indicator is used to compare the currents in the two legs of the circuit and to signal when a ground fault causes the currents to differ. Preferred circuits make use of both these embodiments. Preferably the fault circuits are powered by the same power source as the circuit which is being tested, but the fault indicators continue to signal faults even when the circuit is no longer powered, and both correction of the fault and powering of the circuit are required to cancel the fault indication.

Title: Gas density transducer apparatus
Inventor: WARD ROGER W
IPC: G01N9/00
Filed: 1984-06-07
Granted: 1988-10-20
Abstract: Fluid density measuring apparatus and method for directly measuring fluid density or indirectly measuring pressure, temperature, acceleration, flow velocity, differential pressure and other parameters affecting the apparatus. The apparatus includes a generally rigid hollow housing having openings through which fluid may flow to the interior of the housing, and a vibratory single-ended tuning fork mounted in the housing. The apparatus also includes circuitry for causing the tines of the tuning fork to resonate, for example, 180 degrees out of phase in a transverse direction, with the frequency of the tines varying with variation in the density of the fluid surrounding the tines. Circuitry is also included for determining the frequency at which the tuning fork tines resonate. When the density of the fluid into which the housing is placed changes, the frequency of vibration of the tines of the tuning fork is caused to change to provide a measure of the density change.

Inventor: BURKHARDT HORST DR
IPC: G01D5/244
Filed: 1984-02-08
Granted: 1990-09-06
Abstract: An incremental measuring system is disclosed in which a reference position can be determined at any time. A rotating carrier body carries an additional incremental graduation for which scanning fields are arranged on a scanning plate. During a calibrating operation an additional marking on the rotating carrier body is used to determine coincidence with an associated scanning field. At this point a measuring value counter is started which counts graduation increments associated with rotation of the carrier body by means of associated scanning fields until the measuring value counter is stopped. This stopping of the counter is controlled by a signal generated on coincidence of an additional marking of the carrier body with the next reference mark on the graduated disc which carries the measuring graduation. Simultaneously, an additional marking of the carrier body reads a code mark associated with the reference mark. Each of the code marks contains in coded form the absolute position of the associated reference mark with respect to the zero point of the measuring graduation. The reference position is determined from the counting value of the increments which are superposed on the absolute position value of the overrun reference mark.

IPC: B23K26/08

Abstract: A method and apparatus for high speed welding are disclosed wherein a continuous weld is formed at high speed along a member with a plurality of overlapping welds formed by pulses of high density energy from a pulsed high energy density welding device such as an electronically pulsed gas laser. The movement of the member being welded is detected in the vicinity of the pulsed laser. The pulsed laser is controlled in response to the detected movement so that the energy for welding from the pulses per unit length of the member being welded is accurately controlled. The control of the laser involves pulsing of the laser in response to the detected movement of the member so that the pitch of the overlapping welds along the member is substantially constant. Also, the power of the laser pulses is controlled and adjusted in a predetermined manner in response to the detected movements. The high speed movement of the member is detected by detecting the leading edge of the moving member at or upstream of the pulsed laser and also continuously decteing the position of the moving member at or as it moves past the pulsed laser. High quality welds can be made in materials at speeds of 22-40 m/min. or more with the method and apparatus.
