Title: Competitive indoor game
IPC: A63F7/02
Filed: 1951-02-27
Abstract: 695,988. Table games. WOOLLARD, J. M., and BIMSON, T. May 27,1952. [Feb. 27, 1951] No. 4760/51. Class 132 (ii). Table game apparatus of the type in which a ball is projected up a side channel by a plunger 8 and rolls down channels 1 ... 7 and then returns to the plunger, the ball actuating electric contacts in its passage down the channels, is adapted for the play of a game in which the score to be attained is first set and then the score attained is compared therewith by the apparatus described below. As described, the game is based on football pools, a ball entering channels 1, 4 or 7 scoring one point for a "home" win, channels 2 or 6, two points for an "away" win and channels 3 or 5, three points for a "draw". A bank of playing tables, one for each player, may be provided. A game comprises six matches. Before play commences, an attendant operates keys to set up, on a main display panel, illuminated areas displaying the result 1, 2 or X of each of the six matches and also a total score which is the sum of the points for the six results. A player then operates his plunger, to try to get a ball into the channel appropriate to the first result. If successful, then on his individual display' panel (Fig. 3) the appropriate symbol 1, 2 or X will be illuminated under the heading "Correct Results" in the first line, and a step by step counter will be actuated to illuminate the intermediate points scored under the heading "Total Points". If unsuccessful, the symbol "No Score" is illuminated and the points counter does not operate. The player then makes the other five operations of the plunger, and the appropriate 1, 2, X or "No Score" symbols will be illuminated and the "Total Points" indications will progress. Completion of the sixth operation results in a lamp denoting the end of play being lit on the individual display panel and, if the "Total Points" indication equals the total score indication on the main display panel, then there will be illuminated on the individual display panel a legend "All Correct Line". The apparatus is automatically reset for a new game. A detached electric circuit is described with reference to Fig. 1, not shown.

Abstract: 345,761. Filters. LAMORT FILS, E. ET M., Vitry-le-Francois, Marne, France. Feb. 12, 1930, No. 4766. Convention date, Feb. 22, 1929. [Class 46.] Apparatus for filtering the feedwaters of industrial apparatus comprises a filtering surface within a chamber, an inlet to and an outlet from the space between the filtering surface and the walls of the chamber, an outlet for filtered liquid from the interior of the filtering surface, and movable partitions making joint with the filtering surface and with the chamber walls to divide the space into parts, so that the inlet opens into one part and the outlet into the other and the filter may be cleansed by cutting off the supply to one of its parts and causing the clean liquid coming from the other part to be directed against the clean side of the first part, the clean liquid traversing the first part in a direction opposite to the normal flow and carrying off the impurities. The apparatus comprises a cylindrical cage 4 mounted in a coaxial cylindrical chamber 1 having three pipe connections furnished with cocks 10, 11, 12. The cage makes tight joints at its ends with the chamber 1 and is rotatable by means of a handle 5 projecting through the cover 2 of the chamber. One end of the cage is solid and the other apertured, while the cylindrical wall is perforated all over. Two diametrically opposite bars 6, 7 are secured by screws 8 and make tight joints when in contact with the walls of the chamber 1. Removable sleeves of wire gauze or fabric are gripped between the bars 6, 7 and the cage 4. In the normal filtering position the bars are directly opposite the centre of the pipes, the cock 10 is closed, and the cocks 11, 12 open. One part of the filter may be cleansed by turning the cage into the position shown in Fig. 4, closing the cock 12, and opening the cock 10, so that the water passes under pressure inward through one part of the filter and outward through the other. To cleanse the other part the cage is moved so as to bring the bars 6, 7 to the other side of the inlet and outlet pipes. The space between the sleeve and the chamber wall may be flushed out by opening the cock 10 and closing the cock 12 with the cage in normal filtering position. Alternating movements of the cage may be effected mechanically. Several filters may be connected to one feed pipe, which may be under pressure or vacuum.

Class 139 A clock having an electro-magnetically maintained pendulum or balance comprises a count wheel of ferro-magnetic material, a permanent magnet and a pawl which is operated by the pendulum or balance to rotate the count wheel in a stepwise manner, an impulse lever which pivots on rotation of the count wheel and closes a contact device in the circuit of the maintaining electromagnet. The pendulum carries a pawl 4, Fig. 1, which steps-on the count wheel 2. The count wheel 2 and a lever 3 pivoted on a spindle 18 are magnetized by a permanent magnet 1 so that as the count wheel 2 is stepped-on the lever 3 is rocked clockwise to close the contacts 14a, 15a to energize the coil 13 and impulse the pendulum. The pole 20 of the permanent magnet which lies adjacent the count wheel 2 may be modified as shown in Fig. 4. The driving pawl 4 may have a jewel driving pin which engages the count wheel. The pole of the lever 3 which co-operates with the teeth of the count wheel may be V- shaped to embrace the said teeth and may be adjustably located in the lever 3. Only one of the contacts 14a, 15a need be carried by a spring and the other can be on the lever 3 or on a fixed support. The lever 3 may be carried by a leaf spring: fixed to the magnet, Fig. 12 not shown. In another embodiment the count wheel 61, Fig. 14, is stepped-on magnetically by a pawl 56 which is magnetized by a permanent magnet 50 and has a pole 57 and a balancing counter weight 60. In another embodiment. Fig. 16, a balance 100 has a spiral spring 101 which steps-on the count wheel 2.

Title: Improvements in and relating to electric switching devices responsive to the direction of rotation of a rotatable member
IPC: H01H35/10
Filed: 1947-02-19
Abstract: 638,991. Actuation of switches. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 19, 1947, No. 4858. Convention date, Feb. 19, 1946. [Class 38 (v)] A switch for automatically reversing the connections from a batterycharging generator driven by a railway-coach axle, whenever the coach changes its direction of motion, comprises a frame 1 secured to the generator housing and receiving a recessed extension 4 of the armature shaft 3. A gravity-operated member 6 is pivoted to the extension 4 by a shaft 7 eccentric to the shaft 3, and has its centre of gravity beyond the shaft 7. Axially-displaced arms 8, 9 on the member 6 co-operate, respectively, with correspondingly - displaced shoulders 10, 11 of a switchoperating carriage 12 pivotally connected at 36, 37 to switch members 15, 16 pivoted at 13, 14 in the frame 1, a snap - action being given to the mechanism by a spring 38 compressed between parts 39, 40 pivoted to extensions 43, 44 on the members 15, 16. The members 15, 16 carry spring-mounted contacts 30, 34 which wipe and engage, respectively, fixed contacts 22, 26 and 23, 27, the contacts 22, 23 and 26, 27 being connected by respective strips 21, 25 and terminals 20, 24 to the armature, and the contacts 30, 34 by leads 29, 33 and terminals 28, 32 to the line. If the armature which has been rotating clockwise (Fig. 6, not shown) is brought to rest, then during the first revolution in the counterclockwise direction, Fig. 4, the gravity-operated member 6 pivots on the shaft 7 and the arm 8 engages the shoulder 10 to move the carriage 12 away from a fixed stop 48, the snap-action spring 38 moving the carriage 12 beyond the position to which it was moved by the arm 8 and into engagement with a further fixed stop 49, so that the shoulder 10 is clear of the arm 8 in any subsequent revolution of the shaft 3. This movement of the carriage 12 breaks contacts 30, 26 and 34, 23 and makes contacts 30, 22 and 34, 27 thereby keeping constant the direction of the line current. If the armature had been rotating counterclockwise and then started from rest in a clockwise direction (Fig. 5, not shown), the arm 9 would engage the shoulder 11 and cause a corresponding action. When the generator has run up to speed, centrifugal force acting on the member 6 positions it so that its arms 8, 9 are within the recess of the extension 4, hence there is no likelihood of their 'knocking the carriage 12. In an alternative construction, the bearings 13, 14 are formed by knife-edges.
