Patent GB-633466-A (GB)
Abstract: 633,466. Burners. CROWE, J. M. Oct. 28, 1947, No. 28777. Convention date, Aug. 5. [Class 75 (i)] A fuel burner for furnaces comprises a burner body having a burner nose, means for projecting a stream of gaseous and liquid fuels from said nose, and means for directing oxygen into said stream of fuels so as to impinge thereon at a point spaced a substantial distance from the burner nose. The bumer comprises an atomizing chamber 42 having a liquid fuel inlet 43 and an inlet 44 for atomizing fluid, e.g. steam, the atomized fuel passing to the discharge nozzle through a pipe 30 surrounded by a concentric jacket 31 fed with steam through a pipe 34. Gaseous fuel supplied through an inlet 16 passes through a further concentric tube 12 which is provided with a jacket 10 fed with cooling water through inlet and outlet pipes 20, 21, a blow off or cleaning tube 22 being provided. Oxygen is supplied through an inlet 50 and a control valve 60 to three pipes 51 upwardly inclined within the gas tube 12 to direct a stream of oxygen towards the axis of the fuel tubes 30, 12, to converge upon the fuel stream at a point in advance of the burner tip. The outer ends of the tubes 51 are each supported in the tube 12 by a tip 57 which may be removed and replaced by another of a different size to vary the point of convergence of the fuel and oxygen streams.
Patent GB-776702-A (GB)
Abstract: 776,702. Variable tuned circuits. ALADDIN INDUSTRIES, Inc. June 1, 1955 [June 8, 1954], No. 15695/55. Class 40 (8). A wide-range, e.g. 54 to 890 Mc/s., tuner comprises a coil of non-uniform inductance which co-operates in a variable manner with two energy-transfer sleeves, further sleeves being provided to suppress spurious resonances. The coil 2 comprises a rectilinear or arcuate insulating rod 4 upon which is disposed, e.g. by printing, a conductive strip 3 in the form of a helix of increasing pitch. The coil is capacitively coupled to an external circuit, e.g. a valve oscillator 18, by means of conductive sleeves 8, 9 which are insulated from the coil by a layer 7 of low-loss dielectric. Variation of the inductance between the sleeves 8, 9 is obtained by moving the coil by means of the cam and roller mechanism 11, 16. This inductance is tuned to resonance by stray capacitances and the capacitance existing between the coil and the sleeves. In order to reduce the effect of spurious resonances in the part of the coil outside the sleeves 8, 9 further conductive sleeves 33, 34 are provided. The sleeves 33, 34 may both be left floating or the sleeve 34 may be grounded. Losses due to circumferential eddy currents may be reduced by providing longitudinal slots in the sleeves 8 and 34.

Title: Active imaging systems
IPC: G01S15/89
Filed: 1980-01-09
Abstract: An active imaging system is arranged to transmit interrogating energy, such as ultrasonic energy, toward a region of interest and the energy, having interacted with material in the region, is caused to be incident upon an area detector 10 which is sensitive to variations of the intensity of said energy resulting from said interaction. The system tem includes means 27 for scanning the area detector to liberate electrical signals indicative of said variations and the signals are used to enable a representation of the material in said region to be generated and displayed at 3. In order to obtain ranging information, the scanning of the area detector is periodically arrested and at such times the intensity of the interrogating energy is subjected to a predetermined modulation that can be recognised by suitable circuits 21 and used to evaluate the range of material in said region. <IMAGE>

Patent GB-2052934-A (GB)
Title: Cultivating tool
IPC: A01B33/02
Filed: 1980-06-24
Abstract: A cultivating tool has a pointed flat fixed blade (6) and a curved defector (11) extending upwardly and forwardly from it. Rotary soil- working blades (9) rotate about a shaft (8) driven by an electric motor (12) mounted on a fixed shaft (2) near the fixed blade. This arrangement provides an easily managed light cultivating tool which efficiently breaks up soil and propels it forwardly of the tool, thus avoiding the need for lifting soil. The combination of the fixed blade and the rotary blades minimise the downward force required. <IMAGE>

Title: Touch Switch Device
IPC: H03K17/96
Filed: 1980-07-10
Abstract: A sensor unit, for a touch switch, is operable by simple contacting of a conductive element (2) by the hand for modification of the state of a control circuit by capacitative effect. A touch plate structure has first and second elements (3), (4), for placing for example at one face of a panel such as a door or window, and a third element (2) for placing at the opposite face of the panel. Touching of the third element (2) with the hand effectively earths it and causes a change of state of a switching means connected to the second element (4), as a result of change of A.C. signal transmitted from the first (3) to the third element (2), and from the third (2) to the second element (4). In a preferred embodiment, the A.C. signal is at about 15 KHz and means are included for amplifying the signal received by the second element (4) such that high sensitivity is available to permit the third element (2) to be spaced from the first and second elements (3), (4) by a relatively wide dielectric gap. <IMAGE>

Filed: 1980-10-01
Abstract: In a tumble dryer machine, a motor 7 which drives the drum 5 and circulating fan 6 continues to operate at the end of a drying cycle, but with the air heater 4 cut-out, until the exhaust air temperature sensed at 16 reduces to a predetermined level. The time during which the heater 4 is in operation can thus be reduced. A heat exchanger 2 serves to preheat the incoming air with the exhaust air. <IMAGE>
Patent GB-2086187-A (GB)
Title: Toll barring
IPC: H04M1/673
Filed: 1980-10-09
Abstract: To provide selective toll (or other type of call) barring, the subscriber has his own identification (ID) code. When he wishes to make a restricted call, he keys in this code from the keypad (A), whereafter it is compared digit by digit by a comparator (C) with the ID code as stored in a store (E). If the code is correct, the subsequent equipment including the barred digit comparator (F) is disabled so that normal keysending occurs. If the ID code is not received, the incoming digits are compared by a second comparator (F) with the restricted digit groups as stored in the store (E). If the wanted number is restricted, a relay (R) is operated to cancel the call. A generally similar technique is used to store the ID code, to change the ID code, and to store or change the restricted digits. <IMAGE>

Title: Multi-frequency transducer elements
IPC: B06B1/06
Filed: 1981-05-12
Abstract: A sonar transducer array comprises a number of transducer elements 3, 4 some of which are capable of operating at two different frequencies. The dual-frequency transducer elements 4 have a piezo-electric oscillator 71, 72 sandwiched between an aluminium alloy forward resonator 73 and a steel rear resonator 74.
