Title: Linear/orbital drive mechanism
Inventor: WILLIS PETER CHARLES
IPC: G03B15/00
Filed: 1984-08-09
Abstract: A graphic artwork apparatus for modifying photographic images during exposure comprises a film carriage 2 which moves orbitally, the radius of the orbital motion being adjustable by a linearly movable member. The rotor has a cavity 5 in which ring journal 6 is mounted so as to be slidable in the direction of one of its radii. A drive input shaft 30 supplies drive to a gear assembly in cavity 5. The drive is transmitted to a lead screw 13 when a lever 37 is released and converted to linear drive by engagement of threads thereof with those of colletted nut 11. The linear drive displaces the film plane 2 and causes the axis for rotation of rotor to be eccentric with respect to shaft 30. With lever 37 operated, rotor 1 rotates with its hub 23 and causes orbital motion of film plane 2. An artwork image can be accurately displaced in orbital and linear movements of various characteristics in relation to an underlying unexposed film. An alternative embodiment is described in which separate stepper motors are provided to produce orbital drive through a hub and linear drive via a shaft and lead screw arrangement similar to that described above. <IMAGE>

Title: Safety device
Inventor: LEYLAND STEPHEN W
IPC: G05B19/042
Filed: 1985-06-03
Abstract: A circuit for checking for faults in an output circuit of a microprocessor includes two optical isolators (12,24) connected in series, and an EXCLUSIVE OR gate (16) which has one input (36) drive from the output of the second optical isolator (24) and another input (14) taken directly from the microprocessor output (4). If these two inputs coincide a fault is indicated on line 2. If the output of the microprocessor has changed state in the previous cycle, then a flag is set within the microprocessor and a small pulse will be generated on the fault line (2) even though no fault has occurred. This pulse is latched by a flip-flop (42) and generates an input to the microprocessor on an interrupt line. The microprocessor is then able to check whether the flag was set and reset it. The microprocessor also checks the fault line to see if the fault persists and if so closes the system down to safety. <IMAGE>

Patent GB-2184872-A (GB)
Title: Vehicle lighting system
Inventor: PALMER NORMAN
IPC: B60Q1/14
Filed: 1986-12-22
Abstract: A device is operative to ensure that, while a vehicle's engine is running, sidelights 10 cannot be turned on without dipped beam headlamp filaments 13 being energised also. These filaments 13 are energised by way of a pulsed electrical signal generated by an oscillator 25 and a power switching circuit 26, the pulse length being dependent upon the voltage applied to an input of the oscillator 25. In order to ensure that the light intensity emitted by the filaments 13 remains essentially constant irrespective of battery voltage, a compensator including a zener diode 36 varies the voltage applied to said input in dependence upon any change in battery voltage. The effect of the zener diode 36 is to vary the oscillator input voltage to a larger extent in proportion than the change in battery voltage. The diode 36 is connected via a resistor 35a to the battery voltage at a first point 23, which is in the charging circuit. To compensate for voltage drop in wiring, zener diode 36 is also connected via a diode 52a to a second point, which is the emitter of power transistor 50, the pulse width being dependent on the lower of the voltages at the first and second points. In an alternative arrangement, resistor 35a and diode 52a are omitted and the zener diode 36 is connected directly to the emitter of transistor 50. <IMAGE>
