Abstract: 1446659 Regulating I C engine fuel injection ROBERT BOSCH GmbH 15 Nov 1974 [16 Nov 1973] 49450/74 Heading F1B A fuel injection system for an internal combustion engine includes an air-flow sensor in the engine inlet manifold to determine the injection quantity, the sensor comprising a baffle plate 30 deflectable against the force of a return spring 46, and an additional spring 62 arranged to reduce the restoring force of return spring 46 over a small initial deflection of plate 30, thus increasing the sensitivity of the latter to small air-flows. Plate 30 is mounted on a pivotal hub 44 which also carries a damping vane 43, a slider 70 movable over an electrical resistance track 49, an arm 66 engageable with the outer end 65 of spring 62, and an arm 57 engageable with an electric contact tongue 56. When no air is being drawn into the engine, arm 57 holds contact 59 away from fixed contact 58 so that electrically driven fuel pump (15), Fig. 1 (not shown) remains switched-off. When air is drawn into the engine, baffle 30 pivots anti-clockwise causing contacts 58, 59 to close and switch-on the fuel pump (15). Spring 62 opposes the restoring force of spring 46 over the initial movement of baffle 30 and until its end 65 engages stop 67. The variable electrical signal representative of the position of baffle 30, and hence the air-flow, is fed from slider 70 via lead 50 to a transistor switching device (TS) supplying pulses to control fuel injection valves (11). The electrical circuitry is described.

Title: Circuit arrangement for the simultaneous coupling, holding and releasing of crosspoint relays in a connection path in telcommunication systems, particularly telephone systems
IPC: H04Q3/00
Filed: 1969-10-10
Abstract: 1,240,073. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 10 Oct., 1969 [16 Oct., 1968], No. 49816/69. Heading H4K. In a circuit arrangement for simultaneously operating, holding and releasing cross-point relays in a connecting path through cascaded stages of switching matrices, the cross-point relays are directly selectable via associated marking lines and (except for interstage links involved in concentration or expansion) holding potential and holding counter-potential alternately are applied independently to both ends of every link of alternate inter-stage couplings and for each matrix the potentials applied to the adjacent ends of the associated links can be interrupted simultaneously. The Figure shows four cross-point relays KP in matrices BKV1 to EKV1 in successive stages B, C, D and E of a network, and a common control M. In setting up a path through the relays shown, the matrices BKV1 to EKV1 are selected in a manner not specified and in matrices BKV1 and DKV1 contacts K close. The common control M can then by applying positive potential (+U) to wires VLB1 and VLD1 and to the " 1 " output of matrix EKV1 and applying earth to wires VLB<SP>1</SP>1, VLC<SP>1</SP>1, VLD<SP>1</SP>1 and VLE<SP>1</SP>1 enable the relays KP. The relays each hold over a series contact, associated diodes Da and De and normally closed contacts tl, t2 of associated release relays, one per matrix, not shown. Since for example the link between matrices CKV1 and DKV1 is earthed at both ends, in order to release the relay KP in matrix CKV1 it is necessary to select and operate simultaneously the release relays of both matrices CKV1 and DKV1. Thus, each crosspoint relay can. only be released by the " coordinate ' selection of two release relays. Since the network is a regular one, only one link extends between any two matrices of adjacent stages and thus the selection is unique. If an inlet or outlet of any matrix is connected to two links then instead of applying holding potential or holding counter potential to both ends of each of the two links, the potential is connected twice independently to the common end of the links and the two independent supplied must be interrupted in co-ordinate fashion to release a cross-point relay.

Abstract: 1,104,763. Film evaporators; fractionation stills; chemical reactors. HEAD WRIGHTSON & CO. Ltd. 7 April, 1966 [9 Jan., 1965], No. 50085/64. Headings BIB and B1F. Apparatus which may function as a film evaporator, fractionation still, or chemical reactor comprises a stationary tubular member 10 with a revolvable rotor element 11 concentrically mounted therein and with two series of scraper blades 12 and 13 mounted on a common frame structure 14 in the annular space between the member and the element, the frame structure being revolvable in the direction opposite to that of the rotor element with one series of blades 13 scraping the rotor element and the other series of blades 12 scraping the tubular member. The blades function to transfer material in the form of a film from the tubular member to the rotor element and 'back again (see Fig. I not shown). The material to be located is fed in at 28 and flows down the tubular member by gravity and by the ploughing action of fins attached to the blades, the concentrated material collecting in chamber 17 while vapour formed is discharged through outlets 30 and 18. When the apparatus is used as a still, the rotor element is cooled and the tubular member heated and angled fins on the blades transfer the material in an upwardly direction from member to element so permitting successive evaporation and condensation to proceed, any uncondensed vapour being discharged to an external condenser (Fig. 6, not shown). When used as a chemical reactor the blades ensure good contacting of two liquids or of a gas and a liquid.

IPC: A24C5/47
Filed: 1964-12-17
Abstract: 1,087,094. Cigarette making machines. K. KÍRBER. Oct. 1, 1965 [Dec. 17, 1964], No. 51466/64. Heading A2C. In a device for conveying rod-like articles such as filters, cigarette groups or cigarettes 8 to a station where they are wrapped in a connector or tipping strip 14, the drive for the feeding roll 15 of the strip is interrupted if a test reveals the absence of an article on the conveyer. Pairs of cigarettes 3 and interposed double filters 6 are fed to a drum 4 to form groups 8. Mechanical feelers 25 co-operate with the drum 4 to test whether or not a complete group is present. The groups 8 pass to a drum 9 and have a connector sheet 11 applied at a station 10. The sheets 11 are cut from a strip 14 drawn from a reel 17 by a driven roller 15. The groups are subjected to a further test on the drum 9 by feelers 27 and passed, via a rolling drum 19, to a cutting drum 21 where they are cut into two filter cigarettes for delivery to a conveyer 24. The testing devices 25 and 27 operate switches 26 and 28 connected in parallel in the circuit of an electro-magnet 29. Should delivery of a component to the drum 4 be interrupted the electro-magnet 29 is energized by closure of the switch 26. The roller 15 is mounted on a shaft to which is also fixed a pawl. Rotatably mounted on the same shaft is a driving gear with which the pawl normally cooperates so that the driving gear drives the roller 15, Fig. 3 (not shown). When the electro-magnet 29 is energized the pawl is disengaged from the gear and rotation of the roller 15 ceases. When delivery of a component is again started the electromagnet will remain energized by reason of the action of switch 28 and feelers 27 until the new groups operate to open the switch 28 as well as the switch 25. In a second embodiment, instead of two sets of feelers 25 and 27 a single set may be used which are connected to the electro-magnet via a time delay so that on operation of the switch 25 the feed of the connector strip is not halted until the last complete group has passed the station 10 and feed of the strip is not begun again until the first of a new series of complete groups has reached the station 10 after opening the switch 26. Feed of filter tips may be halted upon interruption of the supply of cigarettes by connecting a further pair of contacts in the switch 26 in a circuit 69, 70 controlling the drive of the filter tip supply mechanism.

Filed: 1967-11-13
Abstract: 1,148,022. Producing polyacetal fibres. CHEMCELL Ltd. 13 Nov., 1967, No. 51561/67. Addition to 962,231. Heading B5B. Polyacetal fibres having improved elastic recovery are produced by subjecting melt-spun polyacetal filaments which have been drawndown from the spinneret at a ratio of at least 25 but have not been subsequently stretched to a dry heat treatment at a temperature of at least 80‹ C. but below the melting temperature of the polyacetal under such conditions that shrinkage of the filaments occurs. The heat treatment may be carried out at a temperature of 120‹ to 150‹ C. It may be carried out at a temperature about 10‹ C. below the melting temperature of the polyacetal. The filaments may be subjected to the heat treatment while they are free to shrink without restraint. The expression " drawn-down ratio " is defined as the ratio of the cross-sectional area of the filament at the spinning orifice to that of the filament as it is taken up or passes over the first godet or other take-up means. The heat treatment may be carried out on staple fibres produced by cutting the filaments to staple length. When the treatment is carried out on the filaments, they may be held under sufficient tension to limit the shrinkage occurring, e.g. to 5 to 15% of their original length. In an example, polyacetal resin (trioxane/ethylene oxide copolymer containing 2% oxyethylene groups, melt index 2À5) is extruded at 212‹ C. through a spinneret and the extruded filaments cooled with air as they emerge from the spinneret. The loose yarn is then heat treated in an air oven at 150‹ C. for 30 minutes and then allowed to cool to room temperature.
