Abstract: 807,999. Wick burners; oil heating stoves. FALK, STADELMANN & CO. Ltd. April 18, 1957 [April 20, 1956], No. 12166/56. Classes 75(1) and 126 In an oil burner of the blue flame type air control means acting to reduce the draught to the flame are localized at a point or points amounting to a smal fraction, less than one-fifth, of the circumferential length of the wick so that a white or luminous flame is produced at each of these points. The flame from the circular wick issues from an annular opening 31 formed by a circular aperture 30 in a cover 27 and a perforated spreader 24 fitted to the upper end of an inner wick tube 23. The air control means comprises notches 37a, Fig. 6, in the cover at the edge of the circular aperture 30 or an aperture in the cover near the circular aperture 30. The notches or aperture by-pass the air flow to the adjacent part of the annular flame opening 31 so that tongues 34 of luminous flame are formed. Before reaching the flame opening 31 the air passes through an annular constriction 35 formed between the cover 27 and a flame guard 26 on an outer wick tube 18 and also through a chamber 36 having a radial width greater than its axial length. The metal chimney 15 has a mica window 15a. The burner is mounted in a sheet metal outer casing having a window fitted with a red, yellow or orange glass through which the white or luminous flames are seen and with a second window of clear glass fitted with a hinged opaque cover and used to facilitate wick adjustment.

Title: Improved process and apparatus for multi-burner fuel-fired furnaces
IPC: F23N1/02
Filed: 1966-03-21
Abstract: 1,080,069. Burner control. ESSO RESEARCH & ENGINEERING CO. March 21, 1966 [April 12, 1965], No. 12368/66. Heading F4T. In an oil-fired multiple burner system control of combustion to allow low excess air levels comprises balancing each individual burner 2 to obtain equal flame temperatures and subsequently adjusting the air/fuel feed to the burners simultaneously so that each burner operates at the desired excess air level. Fuel and air is supplied to each burner via a control valve 4 from manifolds 5 and 6. A master control valve 7 regulates the fuel/air ratio to the manifolds 5 and 6. The temperature of each flame 14 is sensed by hollow alumina tubes 3 and signals are conducted through fibre optic conduits 15 to an intercomparing unit 10 which in the event of an unbalance in the flame temperatures electrically signals a feedback control 11 which balances the burner via valves 4. The overall excess air level is determined by a flue gas analyser 8 and this level is periodically compared with the desired level by a master feedback control 12. In the event of a difference in levels a signal is sent through conduit 17 to the master control valve 7 which adjusts the overall fuel/air ratio. A timer in control 12 also periodically actuates through a conduit 16 the control 11 allowing it to respond to any imbalance signal from intercomparing unit 10. The unit 10 may comprise a single optical detector, e.g. a cadmium selenide photoresistive cell, and means for comparing the resistance levels of the detector for each burner and for producing an imbalance signal. Alternatively an optical detector may be placed adjacent each tube 3 and the individual resistance measured and compared manually. Alternative temperature sensing devices may consist of thermocouples, ultra-violet analysers or microwave analysers. Individual valves in the fuel and air lines may replace the dual control valves 4 and 7.

Title: Improvements in steering mechanism
Inventor: STABLE CHARLES EMERY FLEMING
IPC: B62D5/24
Filed: 1953-05-04
Abstract: 786,055. Vehicle power steering. KENT, Ltd., G. May 4, 1954 [May 4, 1953], No. 12386/53. Class 79(5) [Also in Group XXIX] A steering mechanism for vehicles comprises a steering column 1 carrying a steering wheel and connected to the input member 2 of a steering gear (e.g. worm 2 and follower 3) by means allowing limited relative angular movement between the two members, which angular movement is converted to a longitudinal movement of the column to actuate a valve 27 controlling a power device 12 connected to the output member 9 of the steering gear and giving power assistance to the steering movement. The steering column 1 has a pin and cam slot connection 17 with an extension 19 of worm 2 so that a limited longitudinal movement is possible between the two members. Column 1 also carries a flange on which centralizing springs 21, 22 act, and the flange is connected by a lever 25 to valve 27. The movement of piston 12 reacts back through lever 9 and follower 3 to rotate cam 2 and extension 19. The axial movement thus imparted to column 1 will recentre valve 27. Direct manual steering is obtained as soon as the lost motion between a pin 31 on the column and the edges of an opening 32 on the shaft 19 has been picked up. In a modification, a screw-and-nut 'connection replaces the pin and slot 17.

Title: High frequency wave transmission systems
IPC: H03H7/01
Filed: 1939-04-25
Abstract: 527,988. Wireless signalling; aerials. STANDARD TELEPHONES & CABLES, Ltd. April 25, 1939, No. 12403. Convention date, April 28, 1938. [Classes 40 (iii) and 40 (v)] A " blocking device " or coil-less resonator, to prevent the leakage of high-frequency energy along an aerial feeder or other transmission line, consists of two sliding parts which are tuned to act as a rejector circuit by adjusting the distance between them. The device serves to confine the spread of high-frequency energy, without breaking the electric continuity of the line to which it is attached. It is used to maintain the symmetry of the field radiated from a beacon transmitter of the overlapping-beam type, or of a " beam " array of aerials. whilst allowing the effective length of the aerial to be varied if necessary. As shown in Fig. 1, high-frequency energy is fed through the coaxial line 3 to the centre of the dipole 1, the current in the two parts of the line being in phase-opposition and spreading upwards along the limb A of the aerial and downwards along the limb B. The blocking device 5 prevents the energy in the lower limb from leaking past the cap 6. It also helps to remedy any lack of balance in the push-pull energy supplied through feed-line. As shown in Fig. 4, it consists of a cap portion 6 and a body portion 7, both of which can be adjusted relatively to each other by means of screws 8. The two parts enclose a toroidal cavity 9 simulating inductance, which is tuned in combination with the capacity between the cap 6 and flange 10 to act as a rejector circuit to the carrier wave. Two or more such devices may be arranged in cascade on the same feed line. Fig. 2 shows a beam transmitter comprising a main dipole 4 and two reflectors 21, 31 controlled by keying relays 22, 32, the blocking device being shown at 7 on the feed line 3. In Fig. 3 the resonators 7 are arranged at the junction point 11 of the feeders 3, 31 for an aerial beam array and also near each of the radiating elements 1, 1<SP>1</SP>.

Title: Improved Device for Replenishing an Engine Sump with Oil
IPC: F01M11/06
Filed: 1968-03-14
Abstract: 1,160,195. Lubricating. C. VOGEL, [trading as WILLY VOGEL]. 14 March, 1968 [31 March, 1967], No. 12454/68. Heading F2A. An engine sump 11, Fig. 1, supplies lubricant to an internal combustion engine for a motor vehicle and is replenished with lubricant from a replenishing tank 21. The sump 11 is provided with a level maintaining pipe 13 which is connected to a pump 18 by means of a pipe 14 and a valve 15. The tank 21 is connected to the pump 18 by means of a pipe 22 and a valve 23. The pump 18 is actuated periodically by means of a piston 37 of a compressed-air cylinder 36, the piston 37 and the piston of the pump 18 having a common piston-rod 28. In use, at periodic intervals when the vehicle has travelled pre-determined distances, the piston 37 is moved to the left by means of compressed-air which is supplied by a pipe 39, via an electrically-actuated air-valve 40. The movement of the piston of the pump 18 to the left causes a portion of the lubricant which has been supplied to the pump from the tank 21, via the pipe 22 and the valve 23, to be returned to the sump, via a valve 31 and a pipe 30; the other portion of the lubricant being forced to distributers 34, 35 of the central lubricating system, via a pipe 33. Both the piston and the cylinder of the pump 18 are stepped so as to effect the required differential pressures of oil. As the lubricant is being forced from one side of the piston, lubricant is also being received at the other side of the piston, the lubricant being pumped from the sump 11, via the pipe 14 and the valve 15. At a pre-determined pressure a lubricant pressure switch 51 closes; the air-valve 40 is returned by a spring (not shown); the piston 37 is moved to the right by means of compressed-air supplied via a pipe 38; and lubricant, which was drawn into the pump from the sump 11, is forced into the tank 21, via a valve 20 and a pipe 19. In Fig. 3 (not shown), the reciprocating pump, Fig. 1, is replaced by a pair of rotary pumps and a floatcontrolled tank is provided intermediate the replenishing tank and the pumps.
