Title: Improvements in or relating to Spark Ignition Internal Combustion Engines
IPC: F02M35/10
Filed: 1968-06-12
Abstract: Mixture is supplied to the combustion chamber 2 of a spark-ignition I. C. engine from a pair of carburetters 7 and 10 through respective induction passages 5, 6 and 8, 9 opening into the combustion chamber through respective valve controlled ports. The passage 8, 9 and its respective port are of larger cross-sectional area than the passage 5, 6 and its respective port and the carburetter 10 supplies a mixture suitable for maximum engine output and the carburetter 7 mixture for low output or idling.

Title: Device for producing bursts of charged particles
IPC: G21K1/087
Filed: 1968-10-18
Abstract: In a device for producing sharply-edged bursts of e.g. neutrons from a target 4 by bombarding it with sharply-edged bursts of accelerated, e.g. negative, ions travelling along the path 2, the bursts of ions are produced by a deflecting device comprising an earthed, extensive plate 10 and a series of positively biased, equally spaced small plates 12 which are interconnected through coaxial cables 14 for delaying pulses of equal amplitude, but opposite polarity to the bias voltage transmitted between a generator 16 and a matched load 18. The delay introduced is equal to the time taken for the ion beam to pass between two of the plates 12 and hence during the time interval separating two pulses, the beam is deflected on to a diaphragm 8 and during every pulse the beam is not deflected and reaches the neutron producing target 4.

Abstract: A filled container 2 of thermoplastic foil or a laminate of metal and thermoplastic foils has its welded edges 3 held between a flat surface 5 of a base part 1, and ribs 11 of a part 10 of an upper frame 25, the measurement of the thickness of the edges at various peripheral points of the container being considered as indicative of the effectiveness or otherwise of the seal. The frame 25 may be lowered until the part 10 contacts the container and the ribs 11 flatten the edges 3 against the resistance of springs 14, 15, and plungers 16 are moved when the edges 3 are clamped so that the thickness of the edge joint may be measured at several circumferential positions, Fig.2, by a series of dial gauges 18. If all the dials show the same desired reading then the container edges are regarded as being perfectly sealed. The containers may be conveyed to the apparatus and moved testing into position by a vertically movable table 20, and imperfectly sealed containers may be automatically rejected and conveyed away or signalled by means responsive to the vertical displacement of the plungers connected by electric leads 21 to suitable apparatus.

Patent ES-379564-A1 (ES)
Title: Stop motion devices
IPC: B65H63/06
Filed: 1970-05-12
Abstract: A stop motion comprises a drop wire 26 which can move about either of two mutually perpendicular axes (at right angles or parallel to shaft 74), and upon such movement close a circuit between two bus bars 14, 16. The bus bars 14, 16 are mounted on a elongate support 10 which also carries the switch housing for the drop wire. As shown, if the yarn breaks drop wire 26 will rotate shaft 74 about its longitudinal axis and provide electrical connection between contacts 78 and 40. The latter are connected to bus bars 14 (via contacts 48 and 60) and 16 (via part 42) respectively. If fibre build-up on the drop wire causes it to move in the direction of the yarn, shaft 74 will pivot on the switch housing and part 72 of the shaft will lift contact 48 so as to engage its lower end 52 with the edge of the hole in contact 40. In alternative embodiments the drop wire may rotate about shaft 74 to close the circuit as in the above embodiment, but upon movement in the direction of the yarn the whole switch housing 34 tips away from the bus bars. This tipping movement enables (a) two contacts (90, 98, Fig. 5a) to connect the bus bars or (b) permits an external extension (116, Fig. 7a) of the contact connected to the bus bar 16 to bear against the upper bus bar 14, or (c) permits a resilient contact (122, Fig. 8a) to spring against the two bus bars.
