Title: Power supply for fluorescent lamp
Inventor: ASHWORTH STEPHEN KENNETH
IPC: H02H7/122
Filed: 1988-08-18
Abstract: A power supply has the mains connected through a radio frequency interference filter (1) and full wave rectifier (BR1) to a free oscillating boost converter (2) controlled by a circuit (6) to provide regulated high voltage DC power which feeds a high frequency oscillator (3) having fluorescent lamps (4, 5) forming its load. A voltage divider (R27, VR2) provides a low voltage representative of the high voltage DC power to an input of the control circuit (6). In a first comparator (8), this input is compared with a fixed reference voltage to produce an error signal. A circuit (10) multiplies the error signal with a sine- magnitude voltage from the output of the rectifier (BR1) to produce a variable control voltage for transistor (T1). Diodes (ZD3, ZD4, ZD5) connected in parallel to part of the voltage divider (R27) break down when the voltage of the high voltage DC power supply is excessive. This causes a high voltage to be input to the control circuit (6) to shutdown converter (2). Voltage clamps limit the magnitude of the sine-magnitude voltage applied to the multiplier (10). <IMAGE>

Patent GB-894211-A (GB)
Abstract: 894,211. Calculating-machines. OLYMPIA WERKE A.G. June 8, 1959, No. 19451/59. Class 106 (1). A calculating - machine having a selector element arranged to sense the setting pin carriage and also a remotely-controlled input device, and simultaneously to adjust further setting means relative to an output storage device, is characterized in that the selector element comprises a simple pushrod and carries a simple sensing projection for sensing the input device. The selector element or differential lever 1, pivotally connected to a pushrod 4, formed with lugs 38 ... 41, can be set during a machine cycle either by engagement of its nose A with a key-set pin in the carriage (Fig. 1, not shown), or by engagement of one of the differentially-arranged lugs 38 ... 41, Fig. 7, with one of a series of pegs 42 raised by a related solenoid 51 energized from a remote point. The bulkiness of the solenoids &c. necessitates operation via levers 54, as shown in Fig. 6, and the duplication and staggering of the pegs 42 and lugs 38 .. 41 (Fig. 5, not shown). Further setting means receives an entry via an insulated presser member 6 at the rear end of each push-rod 4. Cam-follower levers 63, 64, Fig. 2, lift a guideway 8 supporting the ends of the push-rods 4, causing the presser members 6 to raise selected pins 24 in a box 21. The raised pins, which are retained by spring means, close corresponding contact pairs 34, 35 for transmitting data signals to e.g. a code converter or a remote data-processing machine.

Title: Colour anaglyph 3d television with field rate doubling
Inventor: EZRA JACOB
IPC: H04N13/00
Filed: 1991-03-21
Abstract: Colour cameras 1 capture left and right views of a scene and relay them to time division multiplexer 2 which alternately outputs left view and right view representing fields. These may be stored in video recorder 3 or passed directly to a processor in which they are first demultiplexed 4 to form respective left view and right view signals each having only alternate fields present. The display of such a signal would lead to objectionable flicker and to prevent this the field rate of both left and right view signals is doubled 5, 6 after which they may be encoded into a 3D anaglyph signal 9-11 for display on suitable equipment with doubled field rate. The signal is observed through spectacles 13 having complementary coloured red/cyan filters.   <IMAGE>

Title: Method for identifying drilling mud filtrate invasion of a core sample from a subterranean formation
Inventor: HUNT PATRICIA K
IPC: G01N23/04
Filed: 1991-05-03
Abstract: A drilling mud is used which forms a filter cake during caring of the borehole to limit invasion of drilling mud solids into the subterranean rock to an extent less than invasion of the base fluid in which the mud solids are normally suspended. A dopant is dissolved in the base fluid of the drilling mud to form a solution having an X-ray attenuation characteristic different from the X-ray attenuation characteristic of the connate fluids in the subterranean formation. The core sample is scanned with a computed tomography scanner to determine the attenuation characteristics at a plurality of points in a cross-section in the core sample, from which the depth of invasion of the dopant-base fluid solution into the core sample may be determined. <IMAGE>

Filed: 1991-11-28
Abstract: A four-wheel drive for e.g. a tractor includes a gearbox 3 from which a first drive line 3, 4 to the rear wheels is in permanent torque-transmitting relationship with the gearbox, and a second drive line 3, 6, 8, 10 to the front wheels is in selective torque-transmitting relationship with the gearbox. The second drive line is taken through two switchable freewheeling clutches 11, 12 and includes an actuator 52 whereby each clutch is switchable between its freewheeling and torque-transmitting conditions in such manner that either one coupling is in its freewheeling condition when the other is in its torque-transmitting condition or both couplings are locked in their torque-transmitting condition. The clutches may be frictional to allow gradual take-up or positive, eg dog clutches. Activation of the actuator may be effected during foot braking so that the front wheels may be braked by the rear wheel brakes. In a modification, both clutches may be disengaged. <IMAGE>

Title: Thermostatic valve with an anticipatory control valve
Inventor: SAUR ROLAND
IPC: G05D23/13
Filed: 1992-07-24
Abstract: In a thermostatic valve assembly for a coolant circuit of an internal combustion engine, with a thermostatic working element comprising a housing 17 containing an expansible substance and a working piston 18 adapted to be extended from the housing, an auxiliary valve 24, 23 is arranged to by-pass a main valve 16, 15 and to be opened prior to opening of the main valve. The closure plate 16 of the main valve is attached to the housing 17, while the closure member 24 of the auxiliary valve is secured to the piston 18. In the rest position, the piston is spaced from an abutment 19. Initial rise in temperature moves the piston into engagement with the abutment 19, thus opening the auxiliary valve against the bias of a spring 25. Further movement of the piston 18 being prevented by the abutment 19, continued increase in temperature causes movement of the housing 17 and thus opens the main valve. <IMAGE>
