Title: Improvements in lightning arrestors
IPC: H01T4/12
Filed: 1930-04-04
Abstract: 358,897. Lightning arresters. DUBILIER CONDENSER CO. (1925), Ltd., Victoria Road, North Acton, London.- (Assignees of Schroter, F. ; 15, Ruhlaer Strasse, Schmargendorf, Berlin.) April 4, 1930, No. 10785. Convention date, April 5, 1929. [Class 38 (iv).] A gas-discharge tube lightning arrester for relatively heavy discharges at a high initial discharge potential has electrodes of high melting point materials intimately associated with material capable of producing a vapour for purifying the gases contained in the tube and these gases are such as to ensure a high initial discharge potential. The tube may comprise an internal construction such as a helix 3 to extend the path of the discharge between the electrodes. Tungsten, molybdenum, tantalum, and metals of groups 5A or 6A of the periodic table as revised by Thompson are suitable for the electrodes. Each is surrounded by a shell 12 of magnesium or another alkalineearth metal or even a magnesium-aluminium alloy. A pressed compound of magnesium powder and barium oxide or any other easily-reducible material with an oxide or salt of one or more metals is placed in this shell, such metal being move electropositive than magnesium. The atmosphere in the tube is a rare gas, perferably a mixture of neon and helium at a pressure of from À1 to À5 mm. of mercury. A vapour of an alkaline or alkalineearth metal is also introduced, or the tube may be subjected to a strong discharge to vaporize barium in the electrodes.

Abstract: 375,905. Cutting frogs in bricks. BARKER, O. R., Highfield, Farley Hill, near Swallowfield, Reading. April 13, 1931, No. 10799. [Class 87 (ii).] Frogs are cut in bricks while they are being fed to or from the cutting-wires of the forming- machines. On the forward stroke of the pusher which delivers the batt of clay past the wires W the cam A<1> moves from under the crosshead F and allows the springs C to depress the knives B. The continuing forward movement of the clay then causes the knives to scoop out a layer until they are raised again by the second cam A<2>. On the upward movement the crosshead F trips a latch G and is retained in the raised position until released by hand at the commencement of the next forward stroke. The knives are tapered rearwardly from the bevelled cutting surface so as to clear the severed clay. The apparatus may be inverted so that the knives work upwardly while the clay is held down by a roller or the like.

Title: Improvements in or relating to generators for rectangular wave-forms
IPC: H03K3/30
Filed: 1963-03-20
Abstract: 991,679. Blocking oscillators. SIEMENS & HALSKE A.G. March 20, 1963 [March 21, 1962], No. 11092/63. Headings H3P and H3T. A blocking oscillator comprises a valve or transistor having regenerative feedback via a three-winding transformer, one winding being connected in the output circuit whilst the other two are connected in the control circuit, a semiconductor diode being shunted across the control circuit so as to maintain the output voltage constant between pulses. Both half cycles of the resulting waveform are then substantially rectangular. As shown, transistor T is arranged to be saturated by base current supplied via resistor R1 and winding 2. The collector current increases until the transformer saturates, when the base current is no longer sufficient to maintain the transistor T in saturation. The collector current thus begins to fall so that the transistor T is rapidly cut off by the regenerative feedback action via winding 2 and terminates the positive half cycle across the load R2. The positive potential induced in winding 3 is limited by the forward threshold voltage of diode D1 to a value slightly higher than the supply voltage. The transistor remains non-conductive until the energy of the transformer is reduced sufficiently to cut off diode D1, when a further cycle commences. The mark/ space ratio is dependent on the turns ratio of windings 1, 3 e.g. 1: 1.

Patent GB-345831-A (GB)
Title: An improved calendar or date indicator
IPC: G04B19/243
Filed: 1930-04-10
Abstract: 345,831. Date indicators. CAMPBELL, A., CAMPBELL, S., and CUTHBERT, T. S., 197, Rotten Row, Glasgow. April 10, 1930, No. 11387. [Class 106 (iv).] A daily-changed date indicator comprises bands or other members bearing respectively the dayname, the number of the day and the name of the month and adapted to be stepped forward by manual operation and to be returned automatically under spring action at the end of each week, month and year. In the form shown the bands 17, 18, 19 are wound between drums 10, 11, 12 and 10a, 11a, 12a supported on sleeves and shafts such as 23, 52 and 13. The lower drums are under the influence of spiral springs tending to restore the bands to initial position, and the upper drums are connected with ratchet wheels 22, 36, 51 respectively, adapted to be stepped by pawls 27, 38 and 53. The dayname is changed by manual depression of a spring- controlled rod 21 adapted to rock a sleeve 25a, Fig. 4 and thereby an arm 26 carrying the pawl 27. Reverse rotation of the ratchet-wheel is normally prevented by a detent 29 but at the end of the week a pin 31 on the ratchet-wheel, engaging a loose arm 32 forces this to displace the detent whereupon the band runs back to initial position. The day number is also advanced at each depression of the rod 21, owing to the pawl 38 being connected with pawl 27. The detent 40 preventing reversal of the number band is operated at the end of the month by a rocking-lever 47 pin-and-slot connected to a floating bar 46, raised by a pin 44 on the gear-wheel 43 driven by the ratchet wheel 36. The varying lengths of the months are allowed for by notching the upper end of the bar and adjusting its position so that the moment of operation depends upon which notch is in the path of the pin 44. The position of the bar is controlled by a link 74 and shaft 25 an arm 71, Fig. 3, of which bears by means of a lug 72 against a cam-wheel 70 having a periphery divided into twelve sections differing in radius in accordance with the lengths of the months. Thus in a 31-day month the arm is fully depressed and the bar 46 is forced fully to the left, Fig. 2, so as to be operated only after 31 steps of movement of the day-number band. The month-name band ratchet wheel 51, Fig. 3, is geared with the cam-wheel 70 and is advanced at the end of each month by the rocking- lever 47, Fig. 2, through link 60 and shaft 58, the arm 57 of which releases the actuating pawl 53 mounted on a spring-controlled lever 54. At the end of the year a pin 75 on the cam-wheel rocks a notched arm 77 to rock a non-reverse detent 65 from engagement with the ratchet-wheel whereupon the month band returns to initial position. To provide for the 29 days of February in leap-years a rod 83, Fig. 1, may be turned to insert a stop in the path of lug 72 so that arm 71 is unable to engage the 28-day section of the cam wheel and therefore positions the bar 46 for operation after 29 days.
