Title: An energy saving spotlight
Inventor: DYSON DAVID JOHN
IPC: F21V7/00
Filed: 1995-07-01
Abstract: Two approaches to reducing the energy requirements for lighting are to use an energy-efficient method of light generation and to use some form of optical system to concentrate the light. Both are achieved by using a compact fluorescent energy-saving bulb mounted in a reflector. The reflector required is larger than traditionally used with spotlights but a practical design is possible by using conical reflecting surfaces. A simple method of adjustable mounting may be provided by using a cord and eyelet system.

Title: Arrangement for defining a transmission delay in a subscriber network
Inventor: HURME HARRI
IPC: H04N7/173
Filed: 1994-06-15
Abstract: The invention relates to a arrangement for determining a transmission delay in a subscriber network comprising (a) several subscriber sets (102), (b) several subscriber terminals (101), whereby to one subscriber terminal is connected at least one subscriber set (102) by means of a transmission connection (111) to be implemented in an electrical form and (c) a central unit (103), which is common to the several subscriber terminals and connects the subscriber sets to a public switched telephone network. In the subscriber network a time-division data transmission between the several subscriber terminals and the central unit occurs along a common transmission path (110). According to the arrangement, a value representing the transmission delay between the central unit and an individual subscriber terminal is determined, whereby a transmission of the subscriber terminal (101) towards the central unit (103) is synchronized in the subscriber terminal with a frame structure of a signal to be transmitted from the central unit towards the subscriber terminal. To be able to perform the determination quickly by using a simple equipment and by utilizing the transmission capacity efficiently, there is a specific message transmission time slot in the transmission frame for a transmission from the subscriber terminals (101) towards the central unit (103), whereby the determination of the value representing the transmission delay is performed in the central unit (103) from a message transmitted by the subscriber terminal in said message transmission time slot, by measuring the location of the received message in relation to the frame structure of the signal to be transmitted from the central unit towards the subscriber terminal. <IMAGE>
Patent GB-2298939-A (GB)
Title: Series voltage regulator
Inventor: HOSONO RINYA
IPC: G05F1/569
Filed: 1996-03-15
Abstract: In a series voltage regulator, switches Q3,Q4 prevent current from flowing from a backup capacitor C1 or a back-up voltage supply to the voltage regulator when the control transistor Q1 stops operating, thus reducing the power consumption of the backup voltage supply. The control transistor Q1 is connected in series between an input terminal 1 and an output terminal 2. An error amplifier 4 compares an output voltage detected by the output voltage detector 6 with a reference voltage E3 to control the transistor Q1. A first switching element Q3 cuts off the output voltage detector when the control transistor stops operating and a second switching element Q4 cuts off the error amplifier 4 also when the control transistor stops operating. When the error amplifier is constructed by field effect transistors, the second switching element can be eliminated.

Patent GB-2317065-A (GB)
Title: Reduced power dissipation in FET under reverse polarity
Inventor: TALBOT KEVIN TREVOR
IPC: H03K17/0812
Filed: 1996-09-05
Abstract: A vehicle headlamp 36 is connected in series with a MOSFET 38 between first and second lines 30, 32, connected to ground and the positive terminal of a battery 34 respectively. In this condition, a first oscillator circuit 40 and a voltage pump 42 produce a positive gate-source voltage on the MOSFET to turn on the headlamp. If the battery is connected up the wrong way round so that the second line 32 is at a negative potential, a second oscillator circuit 60 drives the voltage pump 42 thus maintaining a positive gate-source voltage. This ensures that the MOSFET will be turned on when the battery is wrongly connected, thus preventing the need for a large heat sink normally required for the MOSFET because of the high resistance it exhibits when connected backwards without a positive gate-source voltage.

Title: Crude oil separator
Inventor: MOHN FRANK
IPC: B01D17/00
Filed: 1996-10-18
Abstract: A separator for separating crude oil from an oil field production mixture comprises a separator tank 2, a degasser 3 and storage tank 20. The separator tank 2 and degasser 3 substantially reduce the pressure of the oil mixture emanating from a production manifold 1 before passing it onto the storage tanks 20. Under reduced pressure the oil passes into the storage tanks 20 where it separates further into its constituent parts under the effects of gravity for one to three days. The crude oil mixture in the separator tank 2 partly separates into its constituent parts comprising of oil, water and gas under the action of gravity. The oil is drawn out and fed into the degassing chamber 3 where the pressure of the oil is reduced to 1.5 bar. The water is drawn out from the bottom of the separator tank 2 and then cleaned by a production water cyclone before being dumped. Gas from the separator tank 2 and also from degasser 3 is pressurised by compressors 8, 9 and then used in the extraction process by being fed back through the production manifold 1. The water is pumped out of tanks 20 via lines 24 and subsequently the separated oil is also pumped out along line 24 oil to export line 17. The separation apparatus is located on a floating oil production and storage vessel.
