Title: Time lag electrical fuse
Inventor: GAIA ALDINO JOHN
IPC: H01H85/18
Filed: 1986-10-07
Abstract: A composite time lag fuse 45 comprises an insulating housing 46 enclosing a time delay fuse 10 and an electrical resistance heater 30,32 which is located in intimate heat transfer relationship with the time delay fuse. The time delay fuse and electrical resistance heater are connected in a series circuit between a pair of conductive end caps 48,50 closing the ends of the insulating housing. An overload current flow in the electrical resistance heater results in the generation and transfer of heat from the electrical resistance heater to the time delay fuse to cause the time delay fuse to interrupt after a predetermined time delay, the overload current flow being of a lesser magnitude than would otherwise be interrupted by the time delay fuse. For improved short circuit performance, a short circuit fuse is also enclosed in the insulating housing and is connected in the series circuit. <IMAGE>

Patent GB-2209383-A (GB)
Title: Method and apparatus for energy efficient drying
Inventor: STUBBING THOMAS JOHN
IPC: D06F34/14
Filed: 1988-06-03
Abstract: The invention provides a method and apparatus for energy efficient drying of moist material, for example washed garments, using superheated steam as the drying medium. Apparatus for carrying out the method comprises a casing 10 which is thermally insulated and gas-tight apart from an outlet vent 11. The air initially within the casing is circulated by a fan 13 through a heat source 16 and through moist garments 17. The heated air produces steam from the moisture in the garments which, due to resultant increase in pressure in the casing, eventually displaces the air from the casing. Continued recirculation of the steam through the heat source 16 causes it to become superheated. As the process continues, and more moisture is evaporated from the garments, a portion of the superheated steam is continually discharged through the vent 11 where it passes into a condenser where its thermal energy is recovered and is transferred by heat exchange to, for example, water which may be used for other purposes. <IMAGE>

Patent GB-2226374-A (GB)
Title: Brake apparatus for vehicle
Inventor: FUJITA NORIYUKI
IPC: B60T11/34
Filed: 1988-12-20
Abstract: A brake apparatus for a vehicle such as an automobile having two, front and rear, brake systems comprises a proportioning valve 3 and deceleration sensing valves provided in the front and rear brake systems, respectively (not shown). Thus, in the rear brake system, the valve is activated at the same level of hydraulic pressure in both the empty and full-load states to suppress the rise in the hydraulic pressure. Since in both the front and rear brake systems the cut-off pressure in the full-load state is higher than that in the empty state, it is possible to raise the lock critical level. Accordingly, there is neither fear of the steerability of the steering wheel being lost nor risk of the rear end of the vehicle body being swung, which might otherwise cause spinning. Even when either the front or rear brake system is broken, the control of the hydraulic pressure is effected by the deceleration sensing valve in the remaining brake system so that it is possible to ensure the required braking force. <IMAGE>

Title: Adhesive bonded flexible abrasive finishing tool
Inventor: SCHEIDER ALFRED F
IPC: A46D1/00
Filed: 1990-08-17
Abstract: An adhesive bonded flexible abrasive finishing tool and method of making the same includes a cup-shape shank 22 of plastic or metal. Flexible nylon abrasive loaded monofilaments 21 of uniform length are formed into a cylindrical bundle. A measured amount of liquid instant cyanoacrylate adhesive 23 is placed into the bottom of the cup portion of the shank and the bundle of monofilaments is driven as a group endwise by a pressure plate through a split funnel mounted on the lip of the cup so that one end of the bundle and thus each monofilament is driven uniformly into the adhesive which then cures rapidly. The monofilaments may preferably be straight or somewhat crimped or wavy and may vary in sectional configuration and abrasive loading. The resulting brush or finishing tool is a low cost light weight tool having improved distribution and density of filaments and a flat even face without a final trimming operation. The tool is ideally suited for automated or robotics finishing operations. <IMAGE>

Title: Synchronizing a radar receiver
Inventor: BETTS ANDREW MARK
IPC: G01S13/00
Filed: 1990-11-09
Abstract: A receiver for use in a bistatic or multistatic radar system comprises a multiple beam phased array aerial system (1) the reception beam of which is caused by means of a multiplexer (19) and a control signal generator (31) to chase respective pulses transmitted by the system transmitter. The reception beam is arranged to have two components the pointing directions of which lie side by side along the transmitted beam. These components correspond to respective outputs (20, 21 and 22. 23) of the multiplexer. The average difference between the transmitted energy received by these two components is assessed by means of a subtractor (35) and an integrator (36) and the result is used to control the output frequency of a master clock (7) which in turn controls the control signal generator (31) for the multiplexer (19). Thus the chasing is speeded up if the reception beam is lagging too far behind the chased pulses. or slowed down if the reception beam is running too far ahead of the chased pulses. <IMAGE>

Title: Combining digital video signals and photographic film material or the like
Inventor: RICHARDS JOHN WILLIAM
IPC: H04N7/01
Filed: 1990-11-15
Abstract: A system for combining a source digital video signal into 30 frame/s source material, such as film, employs a film scanner 19410 produce a digital video signal from a source film 190, a post-production system 208 for combining with that signal the source video signal (for example from a VTR 200, 204 or camera 198, 202), and a recorder 212 providing a primary output for recording the combined signal on film 192 in 30 frame/s format. The post-production system operates on 30 frame/s progressive scan format signals, so that frame/field conversion of the signals from the scanner and a 30 frame/s progressive scan format source (camera 198 or VTR 200) is not required. An alternative source video signal from a 60 frame/s 2:1 interlace format camera 202 or VTR 204 is converted to 30 frame/s progressive scan format by a converter 206. A number of secondary outputs 218, 220, 222, 224, 230, 234 are provided after conversion of the combined signal to 60 field/s 2:1 interlace scan format by a converter 214. Motion compensated interpolation is employed at stages of frame rate conversion, such as at the converter 214, but this is not required between any of the sources and the primary output. <IMAGE>
