Title: Intrusion detecting device
Inventor: PATRICK JOCELYN BROWNLOW
IPC: G08B13/12
Filed: 1985-04-24
Abstract: An intrusion detecting device 10 comprises a grid of tubes 1 spaced apart a by a distance d sufficient to impede an intruding body. Each tube contains a radioactive luminescent source 3 which transmits radiation that is confined to a narrow beam by a series of aligned apertured masks 5. A detector 4 receives the radiation and provides an input to an AND-gate 6 connected to alarm circuitry 7. The radiation is diverted from the detector 4 if the respective tube 1 is deformed or deflected hence providing a signal to indicate an intrusion. The tubes 1 may form part of a device for preventing an intruder from gaining access to a security zone. Alternatively, the tubes 1 may be flexible to enable the passage of, e.g. fish to be counted. An alternative embodiment (Figure 3) employs intercommunicating tubes with mirrors for guiding radiation from a common source (3) to a common radiation detector (4). <IMAGE>

Title: Frequency synthesisers
Inventor: WILES IAN MICHAEL
IPC: H03L7/181
Filed: 1989-03-15
Abstract: In a frequency synthesiser, oscillations from a controlled oscillator 14 are counted at 16 during a first time interval t, and a control count value is derived therefrom and latched at 28 for controlling the oscillator 14 and the power supplied at least to the counter is switched off by 18 during a second time interval t2. Counter 16 and a counter 12 counting reference oscillations from 12 are enabled during t1. During t2, the count output C1 of 16 latched at 20 is subtracted from a reference count C0 from a register 24. The difference value is again subtracted at 26 from a previously latched value at 28 to derive an error control signal for VCO 14 which is adjusted to zero over a number of cycles. The reference count C0 may be altered for selecting different output frequencies. Frequency mixers, dividers or multipliers may be provided within or outside the control loop. Applications may be in a radio or paging receiver requiring power economy. <IMAGE>
Patent GB-890938-A (GB)
Abstract: 890,938. Valve multi-stable state circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 16, 1960 [Aug. 19, 1959], No. 28384/60. Class 40(6). [Also in Groups XIX and XL(a)] A plurality of cold cathode discharge tubes are arranged in a chain in a counting circuit, Fig. 2. Positive pulses applied from each of two different circuits to the auxiliary anodes fire the tubes in succession in opposite directions. The circuit is thus suitable for moving the discharge in either of two directions, e.g. for adding and subtracting. If a discharge takes place in the first tube then if a positive pulse occurs on the input lead, a discharge will occur between the auxiliary anode of the second tube and the cathode. Thus the second tube is ignited.

Title: Spraygun regulating valve
Inventor: SMITH ROWLAND CHARLES
IPC: B05B7/24
Filed: 1989-06-20
Abstract: A hand held spraygun incorporates a regulating valve which comprises a body (13) with a through passage (14), a venting passage (15) connecting the through passage with the atmosphere, an intersecting passage (16) communicating with the through passage (14) and a rotatable valve stem (17) sealably secured by O-ring (25, 26) in the intersecting passage whereby the valve stem (17) has a through passage at an angle of 90 DEG  to the rotatable axis (19) of the stem so that rotation of the valve stem in the body controls the flow of fluid through the valve. The valve regulates the flow of air to a paint cup, the paint being forced from the cup into the spraygun (Fig 1). Should the pressure in the cup rise unduly, air will flow around the valve stem (17) and out through the venting passage (15). <IMAGE>

Title: Radiation field sensor
Inventor: REES HUW DAVID
IPC: G01R29/08
Filed: 1989-08-18
Abstract: The sensor (10,30,40) incorporates a substrate-mounted dipolar antenna array 30 coupled to microwave radiation by a lens 12. Each antenna (26) has two dipole limbs (26a,26b) connected together via a respective Schottky barrier detector diode 28. Low frequency output signals are fed to respective signal channels each containing a video amplifier (42), an analogue to digital converter or ADC (44) and a multiplier (46). A read-only memory or ROM (48) stores coefficient sets obtained by calibrating the sensor 10, (30,40 figs 2,3) with radiation beams of known parameters such as direction, frequency and/or polarisation. The multipliers (46 fig 3) receive respective coefficients from successive coefficient sets. Each coefficient set provides a respective set of multiplier output products which are summed by an adder tree (56,58,60). A computer (64) establishes which coefficient set yields the maximum sum of products, ie the maximum degree of correlation with the antenna array outputs. Identification of the best correlated coefficient set indicates predetermined radiation beam parameters. The antennas (26) in the array (30) may be mutually parallel, or may be arranged in a variety of inclinations to one another to provide sensitivity to beam polarisation, (Figs 11, 16-19). Dipoles may have differing lengths (fig 12).

Title: Obtaining composition logs of well bores
Inventor: RAI CHANDRA SHEKHAR
IPC: G01N21/35
Filed: 1989-10-25
Abstract: In geophysical exploration, composition logs of the minerals comprising the formations surrounding a wellbore are produced by obtaining samples of the formations surrounding the wellbore at intervals along the length of the wellbore. Each core sample is irradiated with electromagnetic radiation and a spectral response signal is recorded. X-ray diffraction, X-ray fluorescence, IR absorption, and particularly Fourier Transform IR spectroscopy may be used. Peaks in the spectral response signals are located and correlated with minerals exhibiting similar electromagnetic characteristic response peaks. Since the samples were obtained from known depths within the wellbore, a composition log of the minerals comprising the formations surrounding the wellbore can be prepared displaying the minerals identified as a function of depth in the well-bore.

Abstract: An aquaculture system includes an aquatic animal rearing tank arrangement (1 + 6) and an array of separators (2, 3, 4) connected in series for receiving water and water borne materials and life forms from the tank arrangement (1 + 6) and separating out materials and life forms. The array of separators (2, 3, 4) is also connected for providing a return flow to the tank arrangement (1 + 6) after passing through the array. A biological filter (5) is connected with the array of separators (2, 3, 4) for receiving flow from the array and returning the flow to the array after biological treatment. A holding tank (7) is connected with the array of separators (2, 3, 4) for receiving separated out materials and life forms to be held therein for return to the tank arrangement (1 + 6). This holding tank (7) is also connected for providing a return flow to the array of separators (2, 3, 4) and to the biological filter (5). As the system is operated over a period of time continuous circulation of water borne materials and life forms around the system results in an ever-increasing growth of micro-aquatic life, and hence of aquatic animals feeding thereon, so that accelerated animal growth is achieved.

Abstract: In order to determine an absolute steering angle from a steering angle sensor, such as an optical or magnetic encoder for a vehicle, which generates an output signal indicating the relative rotation angle of a steering shaft of the vehicle and at least one reference signal representing a reference position for every one rotation of the steering shaft, the deviation  DELTA ??? between the reference position (A) and an actual straight-ahead driving state position (B) is stored in a memory of a computer which holds the deviation value  DELTA ??? even while the computer is disconnected from a battery, and the absolute steering angle is determined from the relative rotation angle and the reference signal, corrected by the deviation  DELTA  theta . The memory may be non-volatile or have battery back-up. The deviation value  DELTA ??? may be set by turning the wheel to the straight ahead position and operating a setting switch, then rotating the wheel each way so that a reference mark 3 is detected and the amount of deviation  DELTA  theta  may be calculated. …<IMAGE>…
