Title: Improved apparatus for forming and feeding numerically uniform groups of rectangularblock-shaped articles
IPC: B65B35/40
Filed: 1937-09-15
Abstract: 502,182. Endless-belt conveyers; step-by-step conveyers. ROSE, A. G., and ROSE BROS. (GAINSBOROUGH), Ltd. Sept. 15, 1937, No. 25042. [Class 78 (i)] In apparatus for forming numerically uniform groups of rectangular block-shaped articles, e.g. cartons of cigarettes, and feeding the groups separately to a wrapping-machine, the articles pass along a horizontal conveyer channel to a platform which moves upwards after the precise number of articles required to form a group has been deposited thereon, and after the articles have been removed and fed to a wrapping machine, descends to its original position in alignment with the conveyer. The apparatus illustrated is adapted to form and feed groups of cartons of cigarettes, each group of which comprises two rows with five cartons in each. The cartons are placed on endless conveyer belts 29, 30 which are separated by partition 17 and run. between guides 14, 15. The belts are driven by chain-and-sprocket gearing 24, 42, 41 from a cam-shaft 21. A frame 43 slidable in vertical grooves 46, 47 is provided at its upper end with a platform 48 which consists of a series of spaced apart vertical plates 49. The frame 43 is connected by a link 55 to one arm of a bell-crank lever 5 which is pivoted on a spindle 52. The other arm of the lever carries a roller 60 which is maintained in contact with a cam 50 by the weight of the platform and frame. A frame 61 disposed near the .forward end of the con. veyer channel A is slidably mounted in horizontal grooves 64, 65 in the framework and is formed with an abutment member 66 consisting of a series of spaced apart vertical plates 67 which are adapted to pass freely between the plates 49. The frame is reciprocated by a cam 68 through a bell-crank lever 69 and link 70. A guard plate 78 is secured to flanges arranged on the guides 14, 15 and prevents the platform 48 from lifting more than the correct number of cartons as it moves upwards into alignment with the feed channel B. A carriage comprising a pair of sleeves 89, 90 slidable on rods 91, 92 and connected by a cross-spindle 99 is reciprocated by a cam 102 through a roller arm 103, a pair of arms 104, 105 and a connecting yoke 116. A sleeve 117 is rotatably mounted on the spindle 99 and carries a feeding arm 118 and a lifting arm 119. The former has depending pusher members 120, 121. A roller 122 on the free end of the arm 119 engages a slot 124 in an arm 125 projecting from'a sleeve 126 secured to a spindle 128. An arm 127 and link 137 connect the sleeve to an arm 136 on a'sleeve 134. An arm 133 mounted on the sleeve 134 carries a roller 135 which bears against a cam 132. By these means timed rising and falling movements are imparted to the arm 125, and these movements are communicated by the action of the slot 124 on the roller 122 to the arms 119, 118 and the members 120, 121. Brushes 140, 141 are arranged to bear against the cartons at the top of their vertical path and in the feed channel B.

Filed: 1964-06-18
Abstract: 1,064,320. Race games. E. F. JOHANSSON. June 18, 1964 [June 24, 1963], No. 25228/64. Heading A6H. Racing game apparatus comprises a metal or plastics board 1 provided with slots 2, in each of which is mounted a racing model, the models comprising downwardly projecting pins which extend into the path of movement of blades 14 mounted for rotation about a vertical pivot 8 below the board. The blades are mounted on a disc 13 which is adapted for rotation either manually by means of crank 20 or by an electric motor, and serve to progress the models along their respective tracks, but since the tracks are oval in shape, the pins of the models slide along the blades as the latter rotate, and an element of chance is introduced by making the pins of the models of various lengths and providing recesses 15 of various depths in the blades. The chance element is increased by providing a displaceable forked, wedge-shaped member 22 in the mounting of the disc 13, so that the latter, together with the blades 14, may be raised and lowered on the pivot 8.

Title: Radio systems for providing a zone indication about an airport
IPC: G01S1/24
Filed: 1945-09-28
Abstract: 601,277. Radio navigation. STANDARD TELEPHONES & CABLES, Ltd. Sept. 28, 1945, No. 25310. Convention date, Oct. 2, 1944. [Class 40 (vii)] An area such as a zone about an airport is defined by a number of radiators spaced around the area and emitting pulses in such a manner that the boundary of the area is indicated by a predetermined spacing between pulses received at any point on the boundary. An airport, Fig. 4, is provided with four radiators 30-33 simultaneously energized by a common pulse transmitter 34. A craft approaching the airport and occupying successive positions E1, E2, E3 will receive pulses 30-33 spaced as indicated in curves e1-e3, Fig. 5, the predetermined pulse spacing T3 (indicated by the dotted line) occurring when the craft is at point E2 on the boundary indicated at 35. Craft or other courses such as F1-F4, G1-G3 will receive pulses as indicated in curves f1-f4 and g1-g3, the critical spacing T3 again corresponding to the boundary 35. In the receiver, Fig. 3, for use with the system, the pulse output of receiverdetector 14 is fed via a delay device 16, which introduces a delay equal to the time spacing T3 at the boundary condition, to a generator 18 which produces from the first received pulse a rectangular pulse 19 equal in duration to the widest. spacing between successive received pulses. The pulse 19 is fed to a mixer-limiter 20 together with the undelayed received pulses from 14 so that the limiting level 23 is only exceeded by pulses spaced by more than the interval T3. Therefore, only when the craft is outside the boundary will output pulses be derived from 20 and fed to a control unit 25 which causes relay 26 to be energized and the warning lamp 27 to flash. Within the boundary, all pulses fall within the interval T3 and the lamp will light steadily. To prevent ambiguous operation beyond the range of the transmission, a second control circuit 28, fed with the received pulses, maintains a relay 29 closed to complete the lamp circuit only when pulses are received. Other arrangements of pulse radiators, such as three, Fig. 1 (not shown), may be employed, and other indicators such as a cathode-ray tube, which indicates the pulse spacing directly, may be used.

Title: Improvements in and relating to traffic control systems
IPC: G08G1/08
Filed: 1933-09-16
Abstract: 415,893. Road signals for controlling traffic. OPEL, F. VON, 33, Bismarckstrasse, Charlottenburg, Berlin. Sept. 16, 1933, Nos. 25696 and 25697. Convention dates, Sept. 17, 1932 and Oct. 1, 1932. [Class 118 (ii).] Quantities of solid, liquid or gaseous material are measured off in accordance with the traffic passing along a free and a blocked road, the two quantities being compared and the result used to determine the rhythm of actuation of traffic control signals. As shown in Fig. 1, each vehicle passing over road pad À25 operates an electromagnetically operated gate 17 to allow a steel ball to pass from a hopper 13 into a cup 12. A similar pad in a crossing road controls gate 16 to allow balls to fall into cup 11. The beam 10 is thus swung about its pivot and raises or lowers the resistance 5 in the mercury bath 4. The resistance 5 is in the circuit of the motor 2 so that the speed of motor 2, which controls the traffic signals, is controlled in accordance with the traffic. The cups 11, 12 are emptied whenever an amber period is in progress, valves 20, 21 being then closed so that passing vehicles have no effect on the amber timing, but affect the succeeding time period. The balls are returned to hopper 13 by any method such as the carrier illustrated. In order that vehicles may not affect the system after they have passed the crossing, the cups may be shaped as shown in Fig. 2. The balls fall onto the shoot 40 and gradually descend and finally drop out at 28, the time taken being equal to the normal time taken by a vehicle to travel from the road pad to the crossing. The shoot shown is spiral, but various other arrangements can be employed. Systems in which, instead of steel balls, liquid and gas are employed to meter the traffic are described in the Specification. Specification 415,852 is referred to.
