Abstract: 1405125 Planting seeds; plant substrates; growing plants E A H NAUE KG 27 Sept 1972 [21 Oct 1971] 44638/72 Headings AID and A1E [Also in Divisions B8 and Cl] A growth substrate for plants, cuttings or seeds, which substrate is in the form of a sheet or strip and comprises a plurality of individual growth units each of which is integrally and detachably connected around the edges of its base to adjacent growth units and each of which is provided with means for receiving a plant, cutting or seed, said growth substrate being formed of a material comprising an open-celled, chemically neutral, hydrophilic, elastomeric polyurethane foam which is decomposable in the growth process, may be obtained by an apparatus (see Figs. 4 to 7) comprising means for providing longitudinal incisions in a continuous sheet of cellular plastics material, means for providing transverse incisions and means for transversely severing the sheet to form individual growth substrates. The cellular material 71 is passed between a roller shaft 73g having cutting blades 62, 63, and a counter-roller 74, and then passes via a conveyor-belt past transverse cutter 76 which subdivides the sheet into cubes and severs it in the region of the incisions 55. An automatic seed planting drum 75 positioned in front of cutter 76 opens incisions 23 and deposits seeds therein. Subdivided sheets may be compressed and sealed between foils 77a and 77b. A mechanical sower for use in connection with the above substrates, is illustrated with reference to Figs. 8 to 13 and comprises means for prising apart the material around the incisions to form openings and means for introducing seeds into the openings formed. A rubber sheet 95.2 is attached to a hollow drum 95.1 which rotates on the surface of the growth substrate. Projections 95.20 have a recess 95.22 for receiving seed 92.41 which is held in position by means of the vacuum in the internal chamber 95.12. When the drum reaches its lowest point the bore 95.21 in projection 95.20 becomes connected to pressure chamber 95.3 and the seed is ejected into incision 22. A seed feeding drum 95.7 is of similar design to drum 95.1 and is fed by seed pan 95.8. When only a small number of substrates are to be produced the apparatus of Figs. 10 to 13 is used. The principle of operation is as with that of Figs. 8 to 9a but the drum 95.1 is replaced by a vacuum plate 126 suspended from air cylinder 125 and may be moved along a guide rail 123 or pivoted about column 123a so that it is alternately lifted out of seed pan 127 and lowered into growth substrate 31. The seed slots are opened by projections 95.23 (see Fig. 13). The growth substrates may be assembled with heating elements interposed between the rows of plants, seeds, &c.

Title: Electric supply circuits
IPC: H05B6/66
Filed: 1973-09-24
Abstract: 1442181 Supply circuits for microwave ovens HUSQVARNA VAPENFABRIKS AB 24 Sept 1973 [27 Sept 1972] 55653/73 Heading H2H A supply circuit for a microwave oven comprises a transformer 17, a relay contact 18 which connects a main supply to the primary winding of the transformer and a resistor 11 which is short circuited by the contact when the relay winding 15 is energized. When a main switch 1 is closed, a transformer 20 supplies heating current to the cathode 6 of a magnetron 5. At the end of the heating period a contact 9 in a delay circuit 4 is closed to supply current via a closed contact 10, the resistor 11 and an oven door switch 16 to the transformer 17, the secondary winding of which provides the high voltage for the anode of the magnetron. The relay winding 15 is also energized via a switch 12 responsive to the oven temperature, a switch 13 and the closed contact 14 of a timer 19. The contact 18 is therefore changed over to short circuit the resistor 11, which may be a thermistor, and connect the transformer 17 directly to the mains supply. The magnetron is cooled by a fan 21, the supply switch 22 of which is controlled by a thermostat 23 adapted to sense the magnetron temperature. A light emitting  diode 26 monitors the anode current and glow lamps 24, 25 indicate that the supply voltage is applied to each terminal of the switch 10. If the output of the transformer 17 is short circuited, the increased voltage drop across the thermistor 11 prevents the energization of the relay winding 15 so that the relay does not switch excessive fault currents.

Title: Means and method for forming a butt splice in a running web
IPC: B65H19/18
Filed: 1965-10-22
Abstract: 1,070,606. Feeding webs. ZERAND CORPORATION. Oct. 22, 1965 [Oct. 30, 1964], No. 44775/65. Heading B6B. In web-splicing apparatus, the new web-roll R.N., Fig. 1, is previously prepared by securing a knife blade K on one side of the new web so that the cutting edge of the knife is directly over and aligned with the leading edge of the new web WN, Fig. 7 (not shown). An adhesive tape T 1  is secured to the opposite side of the new web, with an exposed adhesive portion extending across the leading edge thereof. When splicing is required, the new web-roll RN is accelerated up to speed by an endless belt 1, which is followed by the urging of the running or old web WO into contact with new web-roll RN by a roller 13. The old web and new web with the knife therebetween pass through a pair of pressure rollers 20, 21 so that the tape T 1  is firmly pressed against and tightly adheres to the old web. A roller 28 has a shaft 29 to which is pivoted via a pair of arms 34, 35, Fig. 2 (not shown), a shaft 36. Normally, the shaft 36 is held in the inoperative position shown in Fig. 1, and the running web changes direction around the roller 28. During the splicing operation, the shaft 36 is moved down to the position shown in broken lines, so that the webs are first deflected through approximately 45 degrees and through a final 45 degrees by the roller 28. As the two webs with the knife therebetween pass through the shaft 36 and the co-operating roller 40, the webs abruptly change direction of travel and consequently the knife K is peeled off the new web, Figs. 3 to 6 (not shown), and in so doing cuts through the old web along the leading edge of the new web to thereby form a butt joint between the new web and the preceding portion of the old web. An angle iron bar 39 and the roller 40 act as a guide and support for the knife K and the trailing edge of the old web. If required, a further adhesive tape T 2  may be applied to butt joint on the opposite side of the joint to the tape T 1 . This tape T 2  is held in readiness on a suction roller 45, which roller is moved by pneumatic cylinder means 50 to engage the roller 28. A detector 61, which detects magnetic material such as the steel knife, forms part of the timing circuit for the suction roller 45. As the knife passes the detector 61, the circuit is brought into operation so that the roller 45 moves towards the roller 28 and applies the tape T 2  directly to the butt joint.

Abstract: 1376683 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 28 Sept 1971 [2 Oct 1971] 44781/72 Heading H4K In a telecommunication system in which a call trace circuit is arranged to supervise at least one subscriber station, to respond to a call trace request tone signal from such a station and to prevent that signal from reaching a calling station, means is provided to respond to a different tone signal from such a station and to open the transmission path between the subscribers to data signals of audio frequency form. As described the call trace circuit is additionally adapted to receive call trace request signals and transmission path opening requests from dial pulse subscribers. The call trace junctor FVS shown can be associated with a subscriber station on a semi-permanent basis or may be taken into use when the class of service of that station so indicates and that station is being called. The junctors can be generally as described in Specifications 1,094,277 or 1,142,740 and include a supply element SpG, a hybrid G, a circuit Sp including a narrow band filter for preventing the passage of a call trace request tone originated from a called subscriber with a push-button multi-frequency sender from reaching the calling subscriber and a gate arrangement for this purpose in the case of a called subscriber with a dial pulse substation, and receivers IWE and TWE for receiving dial pulse and multi-frequency signals respectively and for operating call trace or switch through relays F or D depending on the particular code received from the called station Tln. The relay D if operated changes over contacts d from the positions shown to allow voice frequency data signals free passage between the subscribers. A centrally controlled system in which an intercept junctor, initially taken into use on a subscriber being called, is released and replaced by a conventional junctor, on detection of the said different signal is also outlined.

Abstract: 1,045,444. Cine projectors. MEOPTA NARODNI PODNIK PREROV. Nov. 4, 1964 [Nov. 11, 1963], No. 44892/64. Heading G2E. The film spools of a cine projector are driven by a reversible motor 1 through a multi-stage gear system whereby for reverse projection or fast rewinding, the supply spool 22 may be driven in reverse at either of two speeds. Forward projection is provided through belt 3 driving pulley 4 carrying a spur gear 5 which rotates take-up spool 31 through belt 28, pulleys 27, 29, and the intermediate spur gears 9, 10, 12. Gear 12 engages and drives a further spur gear 16 which is connected to the coaxially mounted pulleys 17 on shaft 15 through a slipping, or unidirectional, coupling so that spool 22 rotates freely as film is drawn off. For reverse projection, motor 1 is reversed, and spool 22 is then driven in the "Z" direction as the above coupling now operates. For fast re-wind, shaft 15 is swung to the left on one arm of lever 14 until friction wheel 18 engages and is driven by wheel 6 at a higher speed than in the disengage position of Fig. 1. The slipping coupling therefore cannot operate and re-winding takes place at the higher speed. Arm 14 may be mechanically connected to the reversing switch for motor 1.

Patent GB-451316-A (GB)
Abstract: 451,316. Transfer mechanism. HOGFORS, H. F. B., 134, Sara Moraeas Võg, Enskede, near Stockholm. Oct. 4, 1935, Nos. 27485 and 27486. Convention dates, Oct. 4, 1934 and Sept. 11, 1935. [Class 106 (i)] In a cash register or like calculating-machine having one or more totalizers 2 ... 4, Fig. 2, engageable with actuating racks 5, the two teeth of each rack that in the zero position of the rack would be opposite a totalizer wheel 1 are replaced by a single transfer tooth 14 movable, after the rack has been reset and the associated totalizer is still engaged, from the position of one missing tooth to the position of the other to effect transfer. Each transfer tooth is pivoted to its associated rack which is raised idly under the control of the depressed keys and is lowered with the selected totalizer or totalizers engaged. After the rack has been restored and if transfer occurs, the transfer tooth is rocked downwardly to add one to the engaged totalizer wheel. At transfer, a tooth 49, Figs. 1 and 2, on the totalizer wheel of lower order, trips a lever 19 pivoted on a slide 17 adjacent the actuating rack, the lever being retained in tripped position by a latch 34 slidable on the slide 17 and urged downwardly by a spring 28 into engagement with a shoulder 30 on the lever. A hooked arm 20 resiliently connected to the trip lever is thus urged outwardly of the slide and, when the rack has returned to zero position, takes over a lug 10<a> on the associated transfer tooth 14. The slides 17 are now lowered in succession by cams 40 on a rock-shaft 41, and the hooked arms 20 that are in operative position rock the associated transfer teeth downwardly to effect transfer. Finally, the slides receive a further downward movement from steps 43 on the cams, during which movement the lower edges 51 of the latches abut a stationary rod 7 thus permitting the trip levers 19 to return to normal position. A plurality of totalizers may be arranged on each line. In a modification, Figs. 10 and 11, the lug 10<a> is carried by an arm 10<b> resiliently mounted on the transfer tooth 14, the arm being provided with a shoulder 10<g> engageable in a notch 16a in the actuating rack normally to lock the tooth in its upper position. The trip lever 19 in this embodiment is formed rigid with the hooked arm 20. At transfer, the lever and arm are rocked and, upon the restoration of the rack, the edge 24<a> of the hooked arm abuts the lug 10<a> and shifts the arm 10<b> to releasing position. Now, upon the lowering of the slides 17 by the cams 40, the hooked arms rock their associated transfer teeth to effect transfer. Upon the restoration of the cams 40, pins 43<a> thereon, through levers 65, 66, raise slides 60 in succession to disable the latches 34 and permit the parts to return to normal position. The locking of the transfer teeth enables the totalizers to be zeroized by upward movement of the actuating racks.
