Title: Flameproof enclosure
Inventor: SANDY ANTHONY OWEN
IPC: H02B1/28
Filed: 1989-03-13
Abstract: A flameproof enclosure is arranged to enable the admission of a movable element (20) into the enclosure whilst retaining the flameproof characteristics of the enclosure. The element (20) enters the enclosures through an opening (21) and carries at each side of the of the opening a planar flange member (23 and 24). Each flange member (23 and 24) has a minimum dimension from the opening (21) to its outer edge and a maximum spacing from the wall (11) of the housing to ensure that the opening (21) is flameproofed. The element (20) can be moved longitudinally a limited amount without destroying the flameproof characteristics of the housing

Title: Coin testing
Inventor: YELLOP ANDREW MICHAEL
IPC: G07D1/00
Filed: 1990-08-10
Abstract: thcoin mechanism comprising testing means for testing coins as to their acceptability and denomination, and accept/reject gate which is normally in a reject position but is electrically powered to an accept position in response to the testing means determining that a coin is acceptable, and an electrically-actuated coin separator adapted to receive the acceptable coins from the accept/reject gate and direct them selectively towards different destinations in dependence upon their denominations as determined by the testing means, characterised by means adapted to provide power for electrical actuation of the coin separator, following failure of electrical power for the accept/reject gate, for a period sufficient to allow the coin separator to complete the direction towards its correct destination of a coin which has passed the accept/reject gate in its accept position. This avoids a coin being directed by the separator to the wrong destination if a power failure occurs after a coin has been committed to the separator but before the separator has directed it to the correct destination, thus avoiding coin jams.

IPC: H05B41/232
Filed: 1991-02-11
Abstract: A fluorescent lamp stabilizer circuit comprises two transistor switches (GB1, GB2) which are switched on alternately and each of which controls a respective one of two charging circuits to provide power for energizing a fluorescent lamp tube R. Each of the charging circuits is connected by way of power terminals 1, 2 to a source of ac power, and the voltage applied to the lamp R is double that of the power supply. A resonance circuit L, C2, R is provided to generate damped oscillation. Once the lamp has started, inductor L drops the applied voltage to the rated voltage of the lamp. The circuit eliminates flashing when the lamp is turned on, and may be used to operate a lamp that had burnt out filaments. <IMAGE>

Title: Crystallization monitor
Inventor: HAYWOOD R BRIAN CHARLES GEORGE
IPC: G01N29/24
Filed: 1991-03-08
Abstract: A crystallization monitor consists of a spherical steel sensor (23) arranged to be immersed in a flowing liquid (18) containing crystals, and connected by a waveguide rod (22) to a transducer (24). Whenever a crystal hits the sensor (23) a pulse of ultrasonic waves travels along the rod (22) so the transducer (24) generates an electrical pulse. The pulse height depends on the crystal size and the nature of the impact. The transducer is connected to pulse height analysis circuitry (34) to determine the distribution of pulse heights, which is connected to a computer (38) to determine therefrom the distribution of crystal sizes. <IMAGE>

Inventor: JEONG SEONG-HYEON
IPC: G11B20/18
Filed: 1991-08-05
Abstract: A method for storing erasure data of a CD-ROM comprises the steps of generating address data for storing substantial data and temporarily latching erasure bits corresponding to the individual address data by sub-block counting (32), generating (38) erasure address data obtained by adding (36-2) said address data and an offset value when the sub-block counting reaches a final value (33), and storing the erasure data in the positions given by the erasure address data by combining the erasure address data and the erasure bits. The data from the CD-ROM may represent computer data or static video data; or it may represent audio data in which case it is transferred directly to speakers. The method enables the data and the erasure data to be stored in a single memory. <IMAGE>

Title: Method of coating inorganic particles
Inventor: HARE ALAN LAWRENCE
IPC: C09C3/10
Filed: 1991-12-12
Abstract: A single-stage method of providing inorganic particles with a polymeric organic coating comprises contacting inorganic particles with an organic compound in the presence of a corona discharge which is produced in a gaseous medium between two electrodes at least one of which is electrically insulated from the medium. The organic compound is caused to polymerise by the corona discharge and a polymer coating is formed on the inorganic particles. Many types of inorganic particles can be coated such as pigments, fillers and extenders and inorganic borides, carbides and nitrides. The organic polymeric coating helps to improve the compatibility of pigments or fillers with organic media and tends to reduce the rate of hydrolysis of solids such as aluminium nitride. The organic compound is, for example, a saturated or unsaturated hydrocarbon, a halogenated or an acrylic compound. in the examples titanium dioxide or aluminium nitride is coated with polyethylene. The gaseous medium is preferably an inert gas. in an apparatus for carrying out the process one electrode may comprise a cylinder and the other electrode is positioned within the cylinder along the axis thereof, and the barrier of insulating material is quartz or glass.

Title: Temperature control in a liquid injecting oil-free screw compressor
Inventor: TOGO HIDEAKI
IPC: F04C29/04
Filed: 1992-03-19
Abstract: A liquid injecting passage 4 leads to an inlet port 3 of an oil-free screw compressor, the liquid passing through a control valve 1 which regulates the quantity of liquid injected. A temperature controller 6 senses the gas temperature in a discharge passage 5 and when the compressor is in a transient state, for example starting or stopping, the temperature controller 6 is switched to control the injected liquid quantity by means of the valve 1 to hold the sensed temperature at a saturation temperature of the gas. During normal operation a flow-rate controller 11 is switched in to increase gradually the liquid flow rate from said injected liquid quantity up to the quantity at which the liquid concentration at the inlet port 3 reaches a predetermined value, or to gradually decrease the liquid flow rate from the predetermined value to said injected liquid quantity. <IMAGE>

Title: Friction clutch driven plates with variable hysteresis
Inventor: CUCINOTTA LUIGI
IPC: F16F15/123
Filed: 1993-11-12
Abstract: A friction clutch driven plate having a friction facing carrier 14 mounted on a hub 11 with damping springs 15, 48 operating in two stages to resist rotation of the carrier 14. First stage friction damping means 40 acts, between the carrier 14 and hub 11, during the initial angular relative rotation. To produce variable hysteresis the first stage damping means 40 has raised areas (52, fig 8) on either side plate 41 or side plate 42, both fixed to the carrier 14, which rub across raised areas (62, 63, fig 6) on flange 43 when the flange 43, which is fixed to the hub 11, rotates relative to the side plates 41, 42. The flange 43 is biased into contact with the side plates 41, 42 by a spring washer 27. Deformation of the flange 43, which may be moulded from a flexible resilient material eg nylon, takes place as the flange 43 moves relative to the side plates 41, 42. The first stage damping means is assembled with the main damper as a pre-built unit. <IMAGE>
