Abstract: 344,380. Issuing and registering tickets. BLACK, H. D., The Island, Uxbridge, Middlesex. Nov. 19, 1929, Nos. 35396 and 37065. [Class 106 (i).] A ticket printing and issuing machine, particularly for use in conjunction with totalizators, of the type described in Specifications 325,873, [Class 106, (iii), Fares &c.], 330,264 and 332,942, [both in Class 106 (i), Calculating &c.], for issuing a ticket bearing a denomination characteristic of a depressed key has means whereby the registration of each ticket issued on registering means associated solely with the selected denomination is effected through contacts on the machine less in number than the number of denominations, the electrical impulses generated passing to decoding mechanism from which the appropriate registering means is actuated. In the construction shown in Figs. 1 and 2 depression of one of the keys 1, pivoted on the spindle 2 mounted in frame members 3, causes the key to engage selectively with an inclined notch 13 on one or more of the bars 4 &c. which are slidable in guide members 10 against the action of springs 11 to effect the closure of one or more of the contacts 12 which pass to decoding mechanism from which actuation of registering means is effected corresponding to the key depressed. In order to balance the side pressure on the keys, the bars 4, 6, 8 may be arranged to move one way and the bars 5, 7, 9 the other way. A gate 26 is provided to prevent depression of more than one key at once. Issuing and registering of tickets for " win " or " place " can be effected by means of a two-way switch operable by a master member 15 as described in Specification 332, 942. Each pair of contacts 12 may be duplicated. In the construction shown in Figs. 3, 4 and 5 depression of a key 1 pivoted on the spindle 2 causes the key to engage selectively with a notch 24 in one or more of the stirrup members 16 .. 21 which are rotatable on the spindle 22 from stops 27 against the action of springs 11a to depress corresponding insulated members 23 carried by one contact of the pairs of contacts 12a to effect their closure and selectively actuate decoding mechanism from which the appropriate registering means is operated. The pivotally mounted keys can be replaced by keys slidably mounted and the invention can be applied to a machine incorporating a depressable rotatable selector arm by causing an arm movable with the selector arm to engage selectively with inclined notches in concentric rings to effect closure of contacts as described with reference to Figs. 1 and 2.

Abstract: 487,248. Dielectric guides for displacement waves. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Dec. 16, 1936, No. 34619. Convention date, Dec. 16, 1935. [Classs 40 (v)] Relates to transmission systems in which short-wave energy, of the order of decimetres, is propagated along hollow tubes, without radiation and, with the electric field vector polarized parallel to the axis of the tube, as - shown in Fig. 3, where a transmitting dipole D3 co - operates with a receiving dipole D4, both set axially to the tube L. For a specified ratio between the radius of the tube and the working wavelength, the field distribution is substantially uniform throughout the tube. The tube may be part of an existing gas, oil, or water supply system. Several wavelengths may be transmitted simultaneously, and may be separately modulated. For instance, an air-filled tube of 20 cm. radius will transmit waves of 52À2, 22À8, 14À5, and 10À65 cms., whilst a water-filled tube of 2À22 cms. radius will carry the same wavelengths equally well. According to the invention means are provided (a) for blocking-off parts of the tube not required to carry high-frequence energy, and (b) for conveying the energy around bends in the tube. Fig. 7 shows how the radiated energy is byepassed around a curve in the pipe-line from the dipole ED through an amplifier V, if necessary, to the dipole SD, wire grids or plates Pi, P<2> blocking the direct path.

Filed: 1922-12-27
Abstract: 191,054. Automatic Telephone Manufacturing Co., Ltd., (Assignees of Blessing, J. G.). Dec. 29,1921, [Convention date]. Impulse transmitters of the dial type have a movable finger-stop which is returned to normal position after the generation of the predetermined number of impulses, and is effective in short-circuiting the impulse springs during the further return movement of the dial. The arm 13 carrying the finger-stop 8 is held in normal position by a pin 10 on the dial, and in the setting operation moves therewith under the action of a spring 20 to the other end of a slot 14, thereby removing an arm 16 from the path of a pin 53 on a gear 52 to permit rotation of the impulse cam, and disengaging an arm 17 from a bell-crank lever 107 to permit engagement of shunt springs 104, 105, 106, short-circuiting the transmitter and disconnecting the receiver. At the end of the fingerstop movement, the lever 107 is engaged by a part 18, causing the removal of the short-circuit from the impulse springs 100, 101. In the return movement, impulses are generated until the pin 10 reaches the finger-stop arm, whereupon the arm 17 moves the lever 107 to short-circuit the impulse springs until the normal position is reached, for a time corresponding to two impulses. The governor comprises a cross-piece 72 of light resilient material with weights 73 carried by leaf springs projecting forward with respect to the direction of motion. A spring detent 81 engaging the driving pinion 71 allows the governor to continue moving after the pinion has stopped. The governor ring 75 forms a common supporting member for the impulse springs, shunt springs, and the terminal block 84. The impulse cam 62 is secured by two nuts by which its position may be adjusted. One end of the main spring is secured to the casing, while the other end is bent at right angles and passes through a transverse slot in the end of the central shaft, so as to prevent endwise movement of the dial. The number-plate is secured by a split-retaining ring 40. Description is given of the assembling of the apparatus.
