Air is supplied to the precombustion chamber 2 by a perforated pipe 19 having a cap 21 with a spindle 13 adjustably screwed into a nut 17 in the pipe 19. Air is supplied to the main combustion chamber 8 by a pipe 9 which extends upwardly from an opening in the base Of the reservoir and passes through the central chamber 3. The upper end of the air pipe 9 has air outlets 25. Air inlets 29 are also formed in the wall 10 of the main combustion chamber and air inlets 28 in the base 4 of the combustion chamber; an air heating chamber 27 is formed below the base 4 by a thermally insulated plate 23 which may have air openings 24. A conical or cylindrical flue pipe 11 is fitted to the combustion chamber; its upper end is open or has outlet openings; it is telescopic, the upper part having downwardy extending rods 14 provided with notches which engage lateral extensions 14a on the lower part. The ratios of the cross-sectional areas of the air inlets, the air supply pipe, the combustion chamber and the flue pipe are given. In a further embodiment (Fig. 3), the lower end of the flue pipe (11) forms the main combustion chamber and is surrounded by a pipe (38) surrounded by a cylindrical sieve (31). Air passes downwardly between the flue pipe (11) and the surrounding pipe (38) to air inlets (29) in the flue pipe. An air blower may supply air tangentially to the lower end of the flue pipe. The upper end of the air supply pipe 9 widens conically. In a still further embodiment (Fig. 4), the flue pipe is enclosed in a chamber which communicates with a further flue pipe containing an adjustable flap. In a still further embodiment (Fig. 5), a wire mesh basket (33) containing solid fuel or waste material is arranged in the lower end of the flue pipe above the main combustion chamber and an upward extension (9d) of the air pipe 9 extends into the basket. A plate (26) on the air pipe 9 with protuberances at its edge serves to collect ash from the basket and to hold methylated spirit for ignition. A plate may be provided below the base 4 of the main combustion chamber for methylated spirit. The flue pipe is in three parts which are hinged together.

Title: Improvements in and relating to radar systems
Inventor: BLACK DONALD HARRISON
IPC: G01S7/282
Filed: 1946-12-18
Abstract: 638,278. Radiolocation. MINISTER OF SUPPLY. Dec. 18, 1946, No. 37257. [Class 40(vii)] A radar system transmits uniformly recurrent groups of pulses or pulse combinations and co-operates with receiving means adapted to receive echo pulses resulting from each pulse or pulse combination of a group, a plurality of displays separately displaying echoes within different predetermined range-bands being associated with the receiving means and the echo pulses being directed to be displayed on the display appropriate to the range-band within which the echo pulse lies. The system permits a radar operating up to long ranges to have a high pulse recurrence frequency. In Fig. 1, independent radars 1-5 each transmit on the same radio frequency at 1000 pulses. per second and operate in rotation at 200 Á sec. intervals, whereby an effective pulse repetition rate of 5000 per second is obtained. Associated with the radars are five displays 11-15 and five rotary beam electronic switches 16-20. The switches move anticlockwise one step every 200 Á sec. to connect each display in turn to each radar receiver. Display 15 is connected to each receiver for the first 200 Á sec. after the corresponding transmitter has pulsed and shows echoes up to approximately 20 miles. Similarly, displays 14, 13, 12, 11 are connected to the receivers for the periods 200-400, 400-600, 600-800, 800-1000 sec. respectively indicating the approximate range bands of 20-40, 40-60, 60-80 and 80-100 miles. Each echo appears on the appropriate display 5000 times per second although the individual radars operate, at 1000 per second. As an alternative to five separate aerials 6-10, one wide-band aerial may be employed with each pulse at a different radio frequency. Fig. 3 (not shown) illustrates a suitable receiver for such a system employing five narrow-band filters to separate the signals. Alternatively, each of five receivers may be connected permanently to one of five displays, the local oscillator frequencies being changed-appropriately by a suitable switching system. A further embodiment, Fig. 4 (not shown), employs a common radio frequency and transmits pairs of pulses at five different spacings. Coincidence circuits responsive to particular spacings separate the received signals. The displays corresponding to the different range bands may appear separately as shown in Fig. 1, or appear on a common multi-beam cathode-ray tube. Alternatively, the displays may be superimposed. optically.

Title: Improvements in or relating to Apparatus for Punching Holes in Paper or Other Thin Material.
IPC: G06C11/08
Filed: 1966-08-30
Abstract: 1,167,023. Selective punching. DATA DYNAMICS Ltd., and T. E. DARLOW. 7 Sept., 1967 [30 Aug., 1966], No. 38674/66. Heading B4B. Apparatus for punching holes in paper or other thin material comprises a punch, drive means and a clutch for coupling the drive means to the punch, the clutch having a driven member adjacent a driving member, one of the members comprising metal and the other member comprising semi-conductive material, and electrical control means for applying a potential difference between the members so that they are attracted together in accordance with the Johnson Rahbek effect whereby the clutch engages to transmit drive to the punch when the control means apply the potential difference. In the form shown, the clutch comprises a continuously rotating cylindrical driving member 11, the outer part of which is made of a semi-conductive material and around which extend ten normally stationary flexible steel bands 14. Each band is connected at one end to an electrical terminal 15 and at the other end to the free end of a pivotally-mounted lever 18 which is held against a stud 10 by springs 20 and supports a link 21. Attached to each of nine of the links 21 is a punch 22 located in a punching block 23. Each of the punches is operated by applying a 300 volt pulse to the associated terminal 15 so that a momentary potential difference is applied between the associated band 14 and the surface of the member 11. The band 14 is accordingly attracted to the surface of the member 11 and is carried around therewith. This causes the lever 18 and the associated punch 22 to be pulled downwards so that the paper tape 24 is punched. As soon as the potential difference between the band 14 and the member 11 is removed, the springs 20 restore the band and punch to their original positions. The apparatus enables one or more punches to be selectively operated. The lower end of the tenth link 21 engages one end of a spring- influenced pivoted lever 25, the other end of which supports a pawl 28 engaging a ratchet wheel 31 mounted on one end of an axle 32 the other end of which has mounted thereon a driving-wheel (33), Fig. 2 (not shown), provided with radial spokes (34) engageable with feed holes in the tape 24. The semi-conductive material is preferably polymeric organic material partially carbonized to form semi-conductive carbon. In a modification, the trailing ends of the bands (14), Fig. 6 (not shown), are attached to leaf-springs (63).
