Abstract: 1,272,460. Garden umbrellas. J. ASPLIN. Oct.22, 1970 [Nov. 3, 1969], No.53734/69. Heading A4P. In a garden umbrella, of the kind comprising a stem 1 and a canopy 2 which can be erected by means of pivoted ribs or struts, the lower end of the stem is tapered and provided with an external screw-thread 6. In the embodiment illustrated the stem is tubular and the lower end is a solid metal plug 3 provided with a shoulder (4), Fig.2 (not shown), which abuts the lower end of the tubing. The plug is held in place by a rivet 5. The stem is screwed into the ground by means of handles 10 which can be swung down from a vertical position adjacent the stem to a horizontal position at right angles to the stem. Alternatively, Fig. 4 (not shown), the handles each comprise a horizontal portion (20) and a portion (21) joining the end of portion (20) to the stem 1. The stem may be formed in sections which fit telescopically in one another, a locking means, Fig.4 (not shown), being provided to hold the sections together.

C. engine communicates through a primary conduit 74 with a primary vortex chamber 75 having swirl vanes 76 at its inlet end and reject slots 70A in its sides wall, the slots 70A communicating with a first collection chamber 71A. The chamber 71A is filled with porous material, e.g. wire mesh, expanded metal etc., which retains particulate material separated from the engine exhaust gas. A vortex finder 72A extends from the chamber 75 into a plenum chamber 73A which communicates with an exhaust tube 74A for cleaned gas.

Abstract: 1,240,315. Facsimile apparatus. AGFAGEVAERT A.G. 21 Nov., 1968 [22 Nov., 1967], No. 55231/68. Heading H4F. [Also in Division G2] A process for producing charge images on insulative surfaces comprises directing a constant corona current towards the surface through a slit in a metal screen, the current being modulated by an imagewise electric field across the gap and varying along the slit, produced by means of a control element on one of the lips of the gap. The control element may be a photo-conductive strip 10 along one edge of a slit 5 in a metal screen 4 which is imagewise exposed. In non- exposed parts of the strip, charge builds up to produce a transverse field across the gap, thus blocking the passage of charging current to the recording surface 6 on a conductive backing 8. By moving the screen 4 relative to the recording material, the image is progressively scanned. Fig. 2 (not shown). With very narrow strips, an auxiliary electrode (15) may be incorporated in the strip, Figs. 4 and 5 (not shown). In a further embodiment the photo-conductive strip is replaced by a number of conductive elements 17 which end on one of the lips of the gap and to which imagewise control voltages are applied, Fig. 6.

Title: Improvements in jet engines for aircraft

Abstract: 1284750 Deflecting propulsion jets H M HOBSON Ltd 13 Nov 1970 [18 Nov 1969 28 Nov 1969] 56447/69 and 58400/69 Heading B7G [Also in Division F2] A thrust reversal system for an aircraft jet engine comprises a pair of thrust reverser buckets 10 movable via an air motor 14 operable by the pilot between a stowed and a deployed position and a mechanism for automatically decelerating the motor as the buckets approach both the stowed and the deployed positions. Bucket actuators 13 are interconnected and driven by encased flexible shafts from the air motor and impart bucket motion through screwshafts 20, links 11, 27 and brackets 12 from a ball servo-actuator comprising a recirculating ball nut motor 25. In operation a pilot-operated selector valve 69, Fig. 3, is moved left under pilot control and compressed air from a compressor of the engine enters the system through solenoid operated combined shut-off and pressure regulating valve 38 so initiating the opening cycle through servomotor 73 which removes bucket locking plunger 76 from a recess 77. Air behind piston 74 then actuates a further servo whose piston 81 operates a directional control valve 83. Actuator 84 associated with this servo then operates interlock valve 92 to bleed valves 119, 120 and dump valves 99, 100 to open snubber valve 88 and brake 89 through their respective servos. Compressed air from passage 68 then passes through 85, the motor 14 to exhaust 87 so driving the buckets. Bucket motion, speed controlled by valve 112, then actuates cam-operated vent valves 41, 42 to bleed air from valves 99, 100 and so close the snubber and apply the brake. To return the buckets for stowage, the pilot de-energizes solenoid 47 of valve 38, the valve being retained open by air from passages 121, 122 until the locking plunger is again engaged in recess 77. Valve 69 is then moved right, connecting servomotor 73 to exhaust and allowing air through passages 70, 124 to move valve 83 and so the motor 14 in the opposite direction. Operation of 83 again actuates interlock valve 92 to disengage brake 89 and open snubber 88. Near the stow position, cam-operated vent valves 102, 103 are again opened, causing bucket deceleration to the stow position where the buckets are looked. The system may be modified by introducing feedback mechanisms, connected to an electrical control valve of the air motor or to the snubber valve, in place of the cam-operated valves. In such cases the snubber valve and/or brake may be omitted.

Abstract: 1390950 Bipolar switching circuit MULLARD Ltd 29 Dec 1972 60033/72 Heading H3T Switching of a hysteresis circuit is effected at positive and negative input voltage levels notwithstanding the use of a supply of one polarity only and one level is determined by the current through a current mirror circuit. The figure shows a bi-stable circuit TR3, TR4, an output amplifier TR6-TR9, a single supply terminal Vcc and a threshold level terminal TC which is directly or through voltage dropping means, connected to the supply terminal. Assuming that the bipolar input signal I/P is positive, transistor 3 will be on and 4 off. When the signal changes polarity and passes - 2V the current drawn through R1 and diodes D3 and D5 exceeds that available from the collector resistor R3 for the base of T3 and accordingly T3 switches off and the bi-stable circuit changes to the state in which TR4 is on. In this state TR6 is on and TR5 therefore off so that the current mirror circuit R2, D1 and TR2 is enabled. Accordingly, when the signal goes positive the current mirror will drain all the input current from R1 until the latter current exceeds the mirror current value whereafter the surplus renders TR1 conductive and resets the bi-stable circuit. This via TR6 renders TR5 conductive and thus disables the current mirror. The switching threshold voltages are thus determined respectively by the mirror current and the current through R3 and may be changed by varying the resistance between Vcc and TC. During normal operation one or other of TR10 and TR12 conducts, except when the input voltage passes through zero, and if the signal remains excessively long in this region, e.g. due to failure, a capacitor C charges sufficiently to render TR11 conducting and thus sets the output to the "0" state.
