Title: Lighting control system
Inventor: LEEVERS DAVID FREDERICK ANDREW
IPC: H05B37/02
Filed: 1987-03-10
Abstract: In a lighting control system, switches (A,B) send signals to electronic processing units (6;60,61) over a low voltage network (7,8). The electronic processing units control the operation of luminaires (1,2,3) in accordance with instructions programmed in a read only memory (10), and data regarding the status of the switches (1,2,3) stored in a random access memory (9). The number of luminaires illuminated as well as the time for which they are lit can be controlled by the electronic processing units, and varied depending on the status of other switches in the system. <IMAGE>

Title: Improvements relating to fishing lines
Inventor: BURGESS PAUL DAVID
IPC: F16G11/02
Filed: 1987-06-12
Abstract: A joint is made between a braided line (1) and a monofilament (2) by mutually telescoping them and drawing the braid longitudinally to contract around the monofilament.

Title: Voltage generation apparatus
Inventor: BALS EDWARD JULIUS
IPC: B05B5/053
Filed: 1987-09-22
Abstract: A 2-stroke petrol engine (10) has a spark ignition system, including a High Tension lead (14) to a spark plug (15), and a winding (23) around part of the lead (14), ends of the winding (23) being connected to a rectifier arrangement (24) from which there is a take off lead (26).

Title: Automatic tensioning "V"-belt pulley
Inventor: JOHNSON FREDERICK PAUL
IPC: F16H61/662
Filed: 1987-12-31
Abstract: Fixed pitch diameter 'V' - groove pulley 21, is locked to a drive shaft and transmits the drive via 'V' - belt 14, to variable pitch diameter 'V' - groove pulley 12/13. The centre distance between pulleys is such that a new 'V' - belt of specific length runs on the mean pitch diameter of the variable 'V' - groove pulley when on full load to give the required speed ratio. One face of the variable 'V' - groove pulley comprises flanged boss 12, keyed to driven shaft 10, and the other, flanged hub 13, a running fit on the boss but interconnected by caged ball bearings 17, running in multi-start screw threads out into the boss 12. If the 'V' - belt tension is insufficient to transmit the load, the flanged boss will slip and slow but the flanged hub 13 under the influence of spring 16, will not and so will screw tighter until tension is increased and slippage ceases. <IMAGE>

IPC: F01N3/28
Filed: 1988-12-23
Abstract: In fabricating an exhaust gas cleaning catalyst at least one sheet-like metal band and at least one corrugated metal band, each being made of a thin metal sheet, are superposed so as to establish contacts therebetween, thereby forming a multi-layered composite body defining a number of network-patterned gas flow passages parallel to the central axis thereof. The composite body is dipped in an electroless plating bath so as to form a brazing coating layer 6 at least in the vicinity of each contact 5 except for the contact itself. The composite body is then subjected to a heat treatment so as to braze the contacts betwen the sheet-like metal band and corrugated metal band. Before dipping the composite body in the plating bath, it may optionally be enclosed in a cylindrical metal casing which is brazed to the composite body at their mutual contacts.

Title: Fast charger for sealed nickel-cadmium batteries
Inventor: WU KO-LEE
IPC: H02J7/10
Filed: 1989-10-25
Abstract: Intermittent constant current charging pulses t2c are applied to a battery until its voltage is sensed to be decreasing continuously. The cycle of pulses is then terminated. Voltage sensing is effected during each charging pulse. A first cycle may commence with a period T1 of relatively short and frequent charging pulses t1c, Subsequent cycles of charging pulses may each commence a predetermined period T3 after the previous cycle, there being fewer short pulses t4c in each such subsequent cycle than in the first. The charging current may correspond to a 3c rate, each main pulse t2c, t5c having a 10 second duration. If the duration, T2 or T5, of the main pulses part of a cycle exceeds a predetermined period before a voltage decrease is sensed, that cycle is terminated. Checks are also made that the battery voltage is within a predetermined range, and for open circuit, short circuit and wrong polarity. A plurality of batteries (281), (282), (Figs 20, 21), may be charged simultaneously by respective constant current circuits (287), (288) operating in sequence so that the respective charging cycles are simultaneous but the charging pulses are interleaved. <IMAGE>

Title: Bicycle speed change mechanism
Inventor: CHEN TSYR-SHIN
IPC: B62M9/16
Filed: 1990-11-06
Abstract: A bicycle speed change mechanism, characterized in that, a stop ring 303 is installed at the front end of a speed change support 305, the stop ring is bent to one side to form a positioning plate 303C that is bent outwardly. One end of a C-type snap ring 302 is installed next to the stop ring 303 and extends outwardly to form a handle 302a. The handle is bent to one side to form an angle plate 302b on which two tapped holes 302c, 302d are formed. When two bolts 301a, 301b mounted in the tapped holes are adjusted, the torsion force of the spring mounted inside the speed change support is accordingly adjusted. Thus, after the speed change mechanism is used for a long period of time, the bicycle chain can still be maintained at a fixed tension. <IMAGE>

Title: Swivel device
Inventor: NODAMA TAKASHI
IPC: F16M11/08
Filed: 1991-06-27
Abstract: In a television receiver swivel device, a turning ring rides on an annular groove on the upper surface of a supporting base so that it is capable of swiveling relative to the supporting base. A television receiver cabinet rides on this 4b turning ring so that it is capable of swiveling relative to the turning ring. A stopper means is interposed between the lower surface of the bottom panel of the cabinet and the upper surface of the supporting base such that swivel motion is possible within a certain swivel range and is prevented from swiveling beyond the swivel range. A manually operated overriding means is provided to override the restriction, so that the television receiver can be swiveled manually beyond 2 said predetermined swivel range to an angle of 180 DEG . A power supply limit switch may further be provided such that electric power to the television receiver is interrupted when the television receiver swivels beyond a second predetermined range (which may or may not be identical to the first-mentioned predetermined range), and is restored when it returns within the second predetermined range. <IMAGE>

Title: Semiconductor memory devices
Inventor: JEON JUN-YOUNG
IPC: G11C11/406
Filed: 1991-08-30
Abstract: A semiconductor memory device 100 has memory cells continuously storing therein given information through rewriting, i.e. a refreshing operation, and is capable of performing non-periodic refreshing operations. The semiconductor memory device 100 internally includes a refresh request signal generator 100A having a reference memory cell 51 connected to a word line in the memory device 100. The refresh request signal generator 100A generates refresh request signals orrs when the potential stored in reference memory cell 51 decreases below a threshold defined by reference Vref. The output refresh request signals cause refresh signals to transfer to all memory cells. Thus, non-periodic refreshing operations are performed only when required (e.g. less frequently if the temperature drops), thereby reducing the power consumption, and increasing the possible amount of data input/output work. <IMAGE>

Filed: 1991-09-09
Abstract: A head lamp cleaner control circuit which is substantially resistive against corrosion duo to moisture and humidity, durable against vibration, is scarcely affected by magnetic fields, and can be combined with the cleaner motor with a simple water-proof structure, employs a semiconductor switching device eg an N-channel MOSFET (TFET) having a source electrode S connected to one terminal of a cleaner motor 3 the other terminal of which is grounded. Alternatively a bipolar transistor may be employed. A drain electrode D is connected to the positive terminal of a power source 9 mounted on a vehicle. A capacitor C6 and diode D4 are connected between the source electrode of the MOSFET and the positive terminal of the power source through an ignition switch 8, so that the capacitor is charged in response to the ignition switch being on. A timer circuit 10-2 starts a timing operation when a cleaner switch 1 is turned on with the ignition switch turned on, to raise the potential level of the gate electrode G of the MOSFET above that of the source electrode, in order to render the MOSFET conductive, and applies the charge voltage of the capacitor to the gate electrode for a predetermined period of time. <IMAGE>
