Title: Radio receptor device for use instead of conductive aerial.
Inventor: CHAMBERS STEPHEN BARRIE
IPC: H01Q7/00
Filed: 1992-07-06
Abstract: An aerial or receptor for a motor vehicle radio receiver has no conventional conductive aerial rod but instead uses a front end circuit C3, L2, C4 coupled with a high gain amplifier TR1 followed by a broad band cascoded stage TR2, TR3, TR4. As electromagnetic radiation is intercepted and passes through C3, L2, and C4 a magnetic field is developed within L2 and also in the associated capacitors. As the RF cycle passes through zero the induced magnetic field within C3, L2 and C4 collapses and a small RF voltage is developed at each end of L2 with 90 DEG  phase difference. The high frequency roll off is determined by C4 and the lower frequencies reflect back from C4 through L2 and C3, the resultant signal at the junction of C5, C3 and R1 is in phase. A broadly resonant circuit L1, C2 provides a higher "Q" over selected frequency bands. Further tuned circuits (STC), (Fig 3), may be coupled between C3, L2, C4 and R1 to increase circuit "Q" at selected frequencies. Dynamic noise limiting may be provided by a noise signal processor, (Fig 4), having an input coupled to the output of amplifier TR1 and providing a noise blanking signal. The receptor circuitry may be built into a rear view mirror of a vehicle.   <IMAGE>

Title: Controlling data storage to enable garbage collection
Inventor: TODD STEPHEN JAMES PAUL
IPC: G06F12/02
Filed: 1992-07-22
Abstract: A data processing system of the type in which a first program 10 interacts with a second, lower level language L.L.L. program 20 comprises means 80 for generating objects within the second program, a memory 60 for storing the objects, and means for associating them with one or more slots allocated to the first program 10. An interface 30 is generated between the first and second programs by the first program and contains object surrogates, each containing an identifier for a given object. To associate one or more of the slots with a particular object surrogate, a surrogate reference identifying the object surrogate is stored by the first program in those slots. During operation of the first program slots may be redefined by erasing old surrogate references and replacing them with different ones. When an object surrogate is no longer associated by any surrogate reference with any of the slots, then a garbage collector 90 informs the second program 20. The data processing system is able automatically to keep track of objects, releasing the user from the burden of having to set up L.L.L. checking routines of his own, and further enabling the system to make much more efficient use of available memory. <IMAGE>

Title: A multi-disk storage device with high data transfer rate
Inventor: SEARBY ANTHONY DAVID
IPC: H04N5/00
Filed: 1992-12-16
Abstract: A data storage apparatus 20 comprises several disc stores 21 to 24 connected to respective RAM buffers 37 to 40 by respective data interfaces and highways 25 to 36. Sets of data are stored in the disc stores with the data in each set being distributed among the disc stores.

The control data is transferred to the disc stores 21 to 24 via the respective data interfaces and highways 25 to 36. When data is ready for transfer a signal is sent from the interfaces 33 to 36 and once the controller has received signals from each of the interfaces it enables data to be transferred between the interfaces and respective buffers. A data highway 49 is provided for connection to external apparatus for a substantially continuous sequential transfer of the data in the identified set or all of the identified sets. Data is transferred between the RAM buffers 37 to 40 and the data highway 49 under the control of the controller 51. The highway 49 may be provided with error checking circuitry 55 to 57. <IMAGE>

Title: Method for determining the slowing down length and the porosity of a formation surrounding a borehole
Inventor: HALL JR HUGH E
IPC: G01V5/10
Filed: 1993-04-08
Abstract: The invention relates to the use of a neutron source (14) and multiple neutron detectors (20-23) in a measurement- while-drilling (MWD) tool to determine the slow down length of neutrons in the formation. The detected count rates are incorporated into multiple simultaneous equations representative of neutron absorption in a borehole. The equations are solved numerically to determine values of formation slow down length, borehole slow down length, a formation constant and a borehole constant. The formation porosity is subsequently derived using the calculated formation slow down length.   <IMAGE>

Title: Oscillator for synchronous video detector using anti-resonant circuit in differential amplifier inputs and feedback
Inventor: HARFORD JACK RUDOLPH
IPC: H03B5/08
Filed: 1994-12-14
Abstract: An oscillator, constructed partially within an IC, includes a differential-input, differential-output, amplifier (Q1, Q2) within the IC. First and second resistive potential dividers (R11 - R16) located within the IC respectively divide the potentials appearing at the first and second output terminals of the amplifier in a predetermined ratio for respective application to the first and second input terminals, thereby respectively completing first and second direct-coupled regenerative feedback connections. An inductor (L1) located outside the IC is connected between the first and second input terminals of the amplifier and is anti-resonated by one or more capacitors (C1 - C3), which may be located inside or outside the IC. In controlled versions of the oscillator, a further differential-input, differential-output amplifier (Q11, Q12) is included within the IC and connected to provide Miller amplification of capacitors used in anti-resonating the inductor. The gain of this further amplifier is electrically controlled for controlling the frequency of the oscillations generated by the oscillator. In addition to providing Miller feedback, which is degenerative in nature and tends in varying degree to reduce the amplitude of oscillations, this further amplifier is arranged for providing regenerative feedback to counteract this tendency to reduce the amplitude of oscillations. <IMAGE>

IPC: H01J17/49
Abstract: 951,083. Discharge devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 12, 1960 [May 25, 1959], No. 5130/60. Heading H1D. [Also in Divisions C4 and G5] A glow discharge tube, Figs. 1 and 2, comprises a stacked plurality of interleaved sets of metal plates 10 each having an edge part 11 defining a fragment of a particular character and each being separated from adjacent plates by a layer of insulating material. Each plate has a terminal lug 12, the lugs being similarly positioned on all the plates of a set but in different positions for each set. Wires 14 are welded to the aligned lugs 12 of each set. The stack of plates is located in a gas-tight container 20 with the edge parts 11 facing a translucent screen 22 of electrically conductive material. The container is filled with neon at 2.5 cms. pressure. Each wire 14 is connected to a terminal 24 and the screen 22 is connected by a conductor 25 to a terminal 26. The screen 22 acts as anode and each set of plates 10 as a separate set of glow cathodes. The plates can be of aluminium, magnesium or molybdenum and if of aluminium or magnesium the plates can be anodized to establish the insulation therebetween, the front edge parts 11 being ground or polished to remove the anodized coating. The plates cam be made by photoetching or by stamping. In an alternative construction, Fig. 11, each set of characterforming members is formed as a series of parallel grid bars 51 in a single support plate 50, each support plate having insulated borders and a terminal. Each bar 51 has insulated edge portions 54. The plates are positioned one behind the other. A high vacuum display device, Figs. 4 and 5, has the stacked plates 10 arranged as in Figs. 1 and 2 with the plates acting as anodes, the bare edge parts thereof being coated with luminescent material. The translucent screen forms a square cathode 25 which is heated by a filament 27 to form electrons which bombard the edge parts of the selected anodes and cause them to glow. The device can be operated by A.C. The arrangement of Fig. 11 can be used in this device.
