Title: Audible warning devices
IPC: G08B7/06
Filed: 1972-12-13
Abstract: 1420603 Selective signalling J ROSE and H SMALL 13 Dec 1972 [8 April 1972] 16325/72 Heading G4H An audible warning device has a plurality of inputs, with holding means, to cause playback of respective audio recordings made on an audio recording medium, simultaneous inputs being resolved according to a predetermined priority order. An alarm condition producing a negative potential at any of input terminals 1 energizes a respective relay 2 (latched via contacts 3), a respective lamp 6, and a common relay 7 (latched via contacts 8). Contacts 9 of relay 7 energize a drive motor 10 and amplifier 11 of a magnetic tape loop playback system, contacts 4 of the energized relay 2 selecting a corresponding read head 12 on a respective track of the tape to feed the amplifier 11 which drives one or more loudspeakers to deliver a verbal statement of the nature and/or location of the condition &c. If more than one relay 2 is energized, only the first in a rank order is effective to control the loudspeaker, due to the series interconnection shown of the contacts 4. A photodetector 16 detects a hole in the tape after one rev. to energize a relay 13, de-energizing relays 2 via contacts 14, and the latching circuit of relay 7 via contacts 15, thus stopping the playback (or this may be done in response to an operator action or after a counted predetermined number of playbacks or after a predetermined time). The input from 1 can be disabled by a push-button 5 acting at 18 but it also acts at 17 to connect lamp 6 to a flasher 19. A button 20 prevents an input 1 from producing playback, but lamp 6 is still lit, and in addition a lamp 21 is flashed on and off while button 20 is actuated. Possible alarm conditions are smoke or machine breakdown in a factory, or pressure, or imminent or actual shortage of fuel, oil, coolant &c. in a car or other vehicle. Instead of a magnetic tape, a mechanical or optical storage medium may be used. Instead of being on different tracks, the messages may be superimposed, using different frequencies. The amplifier 11 may feed an intercom or telephone. Transistors may replace the relays. Manual actuation of inputs 1 may be possible, e.g. for testing. Actuation of an input 1 may also produce machine-switch-off.

Filed: 1964-04-21
Abstract: 1,119,364. Coils for dynamo-electric machines; electrical connections. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 8 July, 1965 [21 April, 1964], No. 16487/64. Headings H2A and H2E. [Also in Division H1] Electrical connections between printed wiring on opposite sides of an insulating board are produced by making holes through the board at the positions where the connections are required, and then cold pressing electrically conductive malleable metal simultaneously through all the holes to form connectors which at each end are enlarged to form heads overlying the printed wiring. The invention is described with reference to the interconnection of conductive paths on a flat rotor for a dynamo-electric machine. As shown, Fig. 1, copper rotor windings 5 applied by a printed circuit technique to both faces of an insulating sheet 4 are interconnected at both ends by holes through the sheet 4, the latter being located on a bed plate 3 having a small recess 14 therein below each hole. A pressure plate 2 above sheet 4 comprises concentric annular grooves 8, 10 having nozzles through their bases in register with the holes in sheet 4, a small recess 15 being formed around each nozzle on the underside of plate 2. Cold indium (not shown) in grooves 8, 10 is pressed through the nozzles by a ram member 1 having annular protrusions 7, 9 which enter grooves 8, 10, the indium being forced into the holes in plate 4 and being headed over the wiring 5 at 14 and 15. In an alternative embodiment, Fig. 4 (not shown), the indium is replaced by a sheet of lead or solder, pellets of which are punched out of the sheet and forced into the holes in sheet 4 and riveted over. These pellets may be subsequently heat bonded to the wiring 5 which may be pre-tinned; alternatively the rivet heads may be pressed to the wiring and sealed with lacquer or varnish to exclude air. A plurality of circuits may be mass-produced on an insulating sheet which is subsequently divided

Abstract: 591,145. Making hollow-ware. SLATER, E. Aug. 30, 1945, No. 16492/44. [Classes 83 (ii) and 83 (iv)] Seaming; cupping.-In the manufacture of a tapered baking tin or like container from a sheet metal blank 1 of substantially cruciform shape having side-forming arms 3 and endforming arms 2, with re-entrant corners therebetween, the blank is pressed by a former through a die having four L-shaped corner members or steels which are displaced outwardly by the passage of the blank so that the side- and end-forming arms are bent upwards about the sides of a base-forming rectangle of smaller dimensions than and symmetrically disposed within a rectangle formed by the reentrant corners and the blank is also folded inwards about lines c extending diagonally outwards from the corners of the base-forming rectangle a, b so as to bring together marginal portions 4, 5 of adjacent arms which are then interlocked to form a double seam. The blank is bent and seamed by means of a tapered upper die co-operating with a lower die comprising an apertured base-plate 6 carrying four L-shaped corner steels 7 which are retained on the plate by projecting overlapping tongues 8 secured to a block 9 on the base and which are movable outwardly against the action of spring thrust pins 11 as the blank is moved into the die opening. Stops are provided to determine the inner position of the steels and the blank is initially located by means of guides 24 shaped to fit the re-entrant angles of the blank. Each of the main steels has fitted in its angle a smaller auxiliary steel 19 formed with a groove 20 shaped to curl the edges 4, 5 to form the double seam. A preliminary steel 21 bolted on to the main and auxiliary steels at each corner overlaps the curling groove 20, but is cut away at 23 to form an entry'slot 'for guiding first the portion of the blank folded about the line c and thereafter the portions 4 and 5 into the groove 20. The stroke of the upper die may be sufficient for a tin to be completed and discharged downwardly through the opening of the lower die. Alternatively, the tin may be removed from the top of the die after the return stroke of the upper die.
