Filed: 1972-10-13
Abstract: 1378810 Pressure alarm systems H LIST 13 Oct 1972 [4 Nov 1971] 47254/72 Heading G1N The pressure and rate of change of pressure inside a closed container are monitored to energize protective devices when the combined signals indicate the approach of an explosive condition. The pressure signal, obtained by a transducer 1, Fig. 2, is compared at 8 with a limiting value set up on a potentiometer 21, and its rate of change, obtained by differentiating unit 5, is compared at 7 with a limiting value set up on a potentiometer 16. Each comparator 7, 8 produces a pulse output when the test input is excessive. When both comparators produce an output signal, an AND gate 22 energizes a monostable switching unit 23 to produce at 27 a signal for energizing control apparatus for e.g. inhibiting the explosion or actuating fire extinguishers. For use with containers in which a thermo-chemical reaction is taking place, a bi-stable switching unit 31 is operated when the comparator 8 produces a pulse output and comparator 7 produces zero output. The transducer 1 may be provided with means for coupling it to a calibrated source of pressure Figs. 3 and 4, (not shown).

Abstract: 1,194,906. Control linkage for swing-wing aircraft. AVIONS MARCEL DASSAULT. 17 Oct., 1967 [1 Feb., 1967], No. 47315/67. Heading B7G. A variable geometry aircraft having wings 4 pivotable about vertical axis 3 on the fuselage 2 has a linkage connecting a control element 15 on the fuselage to a controlled element 20 on a wing, the device comprises an articulated support 6a, 6b which, together with the fuselage joining pivots 7 and 3, and the wing joining pivots 3 and 8, forms a parallelogram linkage, three bell-cranks 9, 10, 11 pivoted respectively to the fuselage at 14, to the pivot 17 of the support, and to the pivot 8, the bell-cranks being connected by rods 12 and 13 to form the transmission. The links 6b and 13 together with the arms of the bell-cranks 10, 11 joining them form another parallelogram linkage. In the neutral position of the control element 15, the pivot 24 joining the link 12 to the bell-crank 9 is aligned with the pivot 7. Consequently due to the parallelogram linkages the controlled element 20 moves with the wing 4. A displaced position of the control element 15 results in the pivot 24 moving to a position 24a, Fig. 7, when movement of the wing about the pivot 3 has very little effect on the position of bell-crank 11 and therefore of controlled element 20 relative to the wing, which may control secondary lift flaps.

Abstract: 1,181,047. Ultrasonic measuring. INTERNATIONAL BUSINESS MACHINES CORP. 16 Oct., 1968 [23 Oct., 1967], No. 49070/68. Heading H4D. In an ultrasonic system, e.g. for measuring the thickness of a document 10, a transmitter 20 and receiver 21 produce a signal representing unwanted signals at the measuring head receiver 15, that signal is subtracted from the output of receiver 15 in a differential amplifier 15, and a circuit 31 compares the time of occurrence of the output of amplifier 15 with that of a receiver 26 operative over a fixed path. In the embodiments the distance-dependent parameter is phase; and undesired effects of standing waves are avoided by unequal angles of transducers with the plane of the document. Potentiometer 40 is adjusted for minimum output of the differential amplifier when document 10 is removed. Utilization circuit 35 may actuate an indicator or alarm when its timeaveraged input exceeds a pre-set magnitude. Circuit 29 (or adjustment of the position of reflector 28) provides for zero setting. In another embodiment a second transmitter-receiver combination, below document 10, ensures correct thickness measurement despite flutter, Fig. 2 (not shown).

Polymeric foam with a flat upper surface is moulded by foaming on a conveyer belt, the sides of which move at the same rate as the conveyer and increase in height at the same rate as the foam rises to keep the top surface of the foam flat. The apparatus comprises a horizontal conveyer 1 lined with paper from reel 4. Paper from reels 5 moves along each sidewall 3 to form a lining. Paper from reels 6 passed inside the other lining, to form a second lining; adhesion to the first lining being by adhesive supplied at 7. The mixture to be foamed is supplied through nozzle 7. On reaching gripper 8 (where the foaming starts), the inner layer of paper 6 is gripped and pulled off from lining 5 breaking the adhesive bond. This paper 6 is attached to forceps 9 on conveyer 10 and is raised at the same rate as the foam rises keeping the top of the foam plane. The paper 6 is then released and continues along the side of the foam block. Conveyer 9 can be moved along the line of conveyer 1 and also raised and lowered to accommodate different rates of foaming and sizes of the finished foam.

Abstract: 1396318 Cigarette making-machines MOLINS Ltd 27 Oct 1972 [29 Oct 1971] 50492/71 Heading A2C In an apparatus for making filter-tipped cigarettes, tobacco is fed into spaces between regularly spaced studs 14 on a first suction conveyer 4, the tobacco sections 16 formed between the studs 14 are carried towards a contnuous wrapper web (22), Fig. 1 (not shown) by a second suction conveyer (20), and filter sections (23) are fed into the spaces between successive tobacco sections 16. Preferably the studs 14 are so sized and spaced as to enable tobacco sections 16 of double cigarette length, with gaps between them each large enough to accommodate a double length filter, to be produced. The studs 14 may be permanently attached to the first conveyer 4 or may be attached thereto by suction. In the latter case, Fig. 9 (not shown), they are temporarily removed from the lower run of the first conveyer band (92), after the depositing of the tobacco sections (95) on a suction transfer wheel (98), and are subsequently replaced and then realigned by a timing device before further tobacco is showered on the band (98) in its upper run. As shown, tobacco showered on the conveyer band 4 initially covers the studs 14, Fig. 2A, but on leaving the shower zone air currents cause most of this surplus tobacco to be redistributed as shown in Fig. 2B. The remaining tobacco 16 on the outermost faces of the studs 14 is then trimmed off to produce a stream as shown in Fig. 2C.
