Title: Aimable head lamp having a discharge lamp
Inventor: MAKITA HIROYUKI
IPC: F21S8/10
Filed: 1991-04-22
Abstract: An aimable vehicular headlamp system has a discharge lamp assembly 12 to be mounted to a vehicle body via aiming screws. The discharge lamp assembly comprises a discharge lamp bulb 50, and a bulb carrier subassembly 18 directly coupled, both mechanically and electrically, to the lamp bulb. Also included is a lighting circuit assembly 14 comprising a ballast section 26 for providing a high alternating voltage, and an igniter section 24 electrically connected between the ballast section and the bulb carrier subassembly of the discharge lamp assembly for causing the lamp bulb to flow by an electric discharge. At least the igniter section of the lighting circuit is mounted to the discharge lamp assembly, typically on the back of a reflector included in the discharge lamp assembly, for joint movement therewith relative to the vehicle body during the aiming adjustment of the discharge lamp assembly. Consequently, the lighting circuit assembly can be electrically connected to the discharge lamp assembly without use of any such elongate cables or cords as have been conventionally employed to this end. <IMAGE>

Patent GB-2258095-A (GB)
Title: Residual current device
Inventor: BRENNAN PAUL VICTOR
IPC: H02H3/33
Filed: 1991-07-26
Abstract: A residual current device incorporates a phase sensitive detector (5) the reference signal of which is derived by way of a phase shifter (3) from the supply phase-to-earth voltage so that the DC output voltage of the phase sensitive detector (5) is proportional only to the resistive component of any leakage current to earth and is insensitive to leakage current taking a capacitive path to earth. This has the important benefit that steady-state leakage current through innocuous capacitive leakage paths such as arising from distributed phase-to-earth cable capacitance and interference suppression capacitors does not contribute to the occurrence of nuisance tripping. A time delay circuit (8) following threshold comparator (7) renders the device immune to transients irrespective of amplitude. <IMAGE>

Title: Induction heating of endless belts in a continuous caster
Inventor: ROSS NICHOLAS V
IPC: B22D11/06
Filed: 1991-10-24
Abstract: An induction heating system 24, 26 is applied to a continuous molten metal casting apparatus having two endless flexible casting bolts 10, 12. The belts are arranged such that front surface of each bolt faces the outer bolt and a pair of dam blocks 18, 20 arranged at the edges of one of the belts along with the belts themselves form a casting region 22. Molten metal is delivered to the casting region to form rectangular sheets of cast metal. Inductive heaters 24, 26 preheat the endless belts prior to the belts' entry to the casting region. This preheating allows for continuous smooth casting by avoiding belt buckling due to uncontrolled expansion. The heaters 24 and 26 may be U-shaped to define spaced legs straddling the same surface of the respective belt and hollow to permit cooling water circulation therethrough. In another arrangement (Figs. 8A and 8B), surface the heaters are in the form of closed loops, each surrounding the respective belt. <IMAGE>
Patent GB-2250461-A (GB)
Title: Strip casting
Inventor: FUKASE HISAHIKO
IPC: B22D11/10
Filed: 1991-10-25
Abstract: For use in the continuous casting of, particularly, ferrous metal strip in a twin roll caster, a trough-shaped metal delivery nozzle 19 is disposed above the nip between the rollers 16. A baffle structure 70 of refractory material is provided in the trough above the nozzle outlet slot 63 to help achieve an even flow of metal across the width of the nip, so as to reduce defects caused by flow variations. In operation, molten metal from tundish 18 falls into the trough and impacts upon the upper face of the baffle structure 70 to absorb energy from the falling stream of metal. The metal then flows laterally on the upper face of the baffle structure 70 before passing downwardly through passages 78 (97, 98 Figs. 8-10) defined between the baffle structure 70 and the trough to form a relatively static pool of metal on the floor of the trough from which the metal flows in a steady relatively slow stream through the nozzle outlet slot 63. Thus the baffle converts a high velocity, relatively uneven stream falling from the tundish 18 into a much slower constant velocity stream over the full width of the nozzle outlet slot 63. <IMAGE>

Title: Feed forward predictive analog-to-digital converter
Inventor: STONE WADE J
IPC: H03M1/40
Filed: 1993-03-25
Abstract: A linear predictive ADC employs a fully feed forward design to extend its dynamic range, allow greater speed of operation, achieve stable operation and eliminate a requirement for sample-and-hold circuits. A first quantizer (Qc) converts an input analog signal to a digital format, while a signal predictor (32) predicts a subsequent value of the input signal. After conversion back to analog format (34), the predicted signal is compared with the actual subsequent value of the input signal (30) to produce an error signal that is converted to a digital format by a second quantizer (Qf). The digital predicted signal is fed forward and combined (46) with the digital error signal to produce a high precision digital output. The analog error signal is preferably amplified (38) prior to digitation to take advantage of the full bit capacity of the second quantizer (Qf), and then digitally de-amplified (40) back to its original scale. Digital gain and offset adjustment mechanisms (44, 50) are preferably provided to compensate for amplification/de-amplification mismatches and system offsets. <IMAGE>
