Abstract: 818,557. Tea and like strainers. SERR, W. F. Aug. 22, 1957 [Aug. 22, 1956 ; Nov. 19, 1956], No. 26590/57. Class 46. A strainer consists of three parts, namely a bowl 1, Fig. 1, with sieve 5, handle 4 and guide member 12b, a drip collector 2 with upstanding supports 6, and a manual control link in the form of a stirrup 3. When the strainer is on a table the parts are in the position shown in Fig. 1. For use the strainer is lifted, and a rearward extension 11 of the stirrup 3, working in a slot 12 of the guide member 12b, Fig. 3, is raised by a finger of the hand grasping the handle 4, whereupon the collector 2 is swung clear of the sieve 5 in a clockwise direction about pivot pins 7 by the stirrups 3 whose ends engage in holes 8 in the supports 6, Fig. 3. When the extension 11 is released the collector returns by gravity to the position of Fig. 1. The extension 11 may have the alternative shape shown in dotted lines. In Fig. 8 the stirrup 3 is nearly horizontal, and its centre part consists of a bridge or trigger 11a above the handle 4 and twin lugs 14 below it (see also  Fig. 11) ; the guide member 12b is omitted. In use the trigger 11a is pushed to the left by the thumb to swing the collector clockwise, the lugs 14 passing either side of a downwardlydirected feather 19, Fig. 8. The feather 19 may be dispensed with and the lugs 14 joined together. When the device is resting on a table the bowl is prevented from tilting clockwise by abutment of a stop 16, Fig. 11, on the handle 4 against the lugs 14. Fig. 10 shows how the stirrup 3 with its bridge piece 11a and lugs 14 may be passed along the handle and over the stop 16 in assembling the device prior to engagement of the stirrup ends in the pivot holes 8, (Fig. 11 showing the assembled position). In Fig. 12, (not shown), the ends of the lugs 14 are joined by a U-shaped member which engages the feather 19 during movement. In Figs. 14 and 15, (not shown), the lugs 14 and feather 19 are dispensed with ; the handle 4 has a dovetail-section rib engaged by a groove in the undersurface of the bridge 11a and the stop 16 is provided at the rearward end of the rib. In Figs. 4 to 6 (not shown), the stirrup 3 is nearly horizontal, as in Fig. 8, and has a vertical extension at its mid-point which engages a slot in the handle 4.

Title: Gas discharge display panel

Filed: 1975-06-26
Abstract: 1519331 Gas discharge display panels MITSUBISHI DENKI KK 26 June 1975 [8 July 1974] 27186/75 Heading H1D [Also in Division G5] A gas discharge display panel comprises a discharge gap defining matrix array of main electrodes 9-16, 17-24 having disposed adjacent and parallel thereto respective auxiliary electrodes 25-32, 33-40 provided with respective series resistors R, the electrodes being arranged on respeotive substrates la, 1b, with the A.C. sustaining drive voltage being applied to the main electrodes through common lines 55, 56 and the turn-on and turn-off pulses being applied to the auxiliary electrodes through resistors R and common lines 53, 54, and wherein switching electrodes 41-46, 47-52 are selectively connected to voltage source Vt such that the full turn-on or turn-off voltage is applied to selected auxiliary electrodes to, in turn, initiate selected discharges between main electrodes. Parts of the switching electrodes, which are located in a different area to the main display area, are covered with dielectric 100 (shown as X in the figure), the arrangement being such that dischargeable positions between the auxiliary electrodes and the switching electrodes are, as shown in Fig. 5, selected according to the binary system and then the state of the switches Sc can be represented by a binary number. With the switches in the positions shown a discharge will occur between the switching electrodes and every auxiliary electrode except 33-thus these discharges produce a voltage drop, corresponding to the resistors R, on each auxiliary electrode except 33, to which is thus applied the full turn-on, or turnoff, pulse. The other set of auxiliary electrodes are similarly addressed so that the full turn-on, or turn-off, pulse is applied to only selected such electrodes. The resistors R may be formed on the substrate by vacuum deposition, e.g. of chromium, or by thick membrane coating. The panel may have a first set of switching electrodes for selecting a character position and a second set of switching electrodes for selecting a character pattern, Fig. 7 (not shown). In an alternative embodiment, Fig. 8, gaps are provided in the auxiliary electrodes between the display part and the switching part, the gaps maintaining electrical insulation while permitting discharges thereacross. The opposite ends of the auxiliary electrodes are connected through resistors r to the common electrodes 55, 56 connected to the main electrodes. With this arrangement a more stable operation is achieved since the voltage at the cross-over points can be clamped to the A.C. sustaining drive voltage. The parts of the auxiliary electrodes on either side of the gaps may be on the same or on opposite glass substrates. In a modification, Fig. 10 (not shown), the main electrodes are dispensed with and the socalled auxiliary electrodes take over their function.
