Title: Fixed timing traffic control system
Inventor: SCHMIDT JACK WILLIAM
IPC: G08G1/085
Filed: 1967-07-26
Abstract: 1,122,768. Road traffic signals. TAMAR ELECTRONICS INDUSTRIES Inc. 26 July, 1967 [16 Aug., 1966], No. 34421/67. Heading G4Q. A traffic signal control circuit comprises a clock pulse generator 12, Fig. 1, feeding a timer 15 which counts the clock pulses and delivers outputs at predetermined intervals to a sequencer 20 comprising a ring counter, various stages of which are coupled by a matrix 22 to switching devices 25 controlling associated signals 26. The clock pulse generator (Fig. 2, not shown) may comprise a 7-stage binary counter fed from an A.C. mains 11 and acting as a frequency divider; one of three different pre-set division ratios may be selected by a manual switch (44), the normal output being, for example, one clock pulse per second. The timer (Fig. 3, not shown) comprises a two-stage decimal counter feeding a matrix (Fig. 4, not shown) provided with terminals which can be connected as desired by key members so as to deliver timing signals to a common output line when the counter reaches predetermined numbers between 1 and 100. In the example illustrated, four key members are placed so that outputs are obtained at counts of 24, 37, 45 and 100. The outputs are fed to a ring counter (Fig. 5, not shown) which as illustrated counts up to 12. Each stage of the ring counter is connected to a matrix (Fig. 6, not shown) so that a desired stage may be connected to a desired output line by means of patch key members. In the example illustrated, stages 1 and 2 are connected to switching devices 1 and 2 respectively, stage 4 to switch 3, stage 8 to switch " N," and stage 9 provides a re-setting signal to all the counters. Provision is made for cycling the sequencer ring counter manually (switch 97, Fig. 5) and for stopping the output of clock pulses (switch 50, Fig. 2)

Abstract: 521,847. Centrifugal dust separators. PARKER, A., and PARKER, J. A. Nov. 26, 1938, Nos. 34457/38 and 27797/39. [Class 23] Dust and grit are separated from gases, such as flue gases, by a separator having a truncated hollow cone 1 in a casing 7 which is partly annular and consists of the side walls 3, 8 and the circumferential wall 9. The inlet 15 is arranged so that the gases enter tangentially the space 10 beween the cone 1 and the casing 7. This space contracts in the forward direction. Part of the conical wall is cut away to permit the gas stream to pass from the space 10 to the interior of the cone, and an opening at the lower part of the cone communicates with the hopper 14. As the gas whirls, the heavy particles of dust are thrown out and enter the hopper 14, the fine dust passes through the open apex of the cone to the chamber 21, and the clean gas passes through the outlet pipe 5. In modifications the gas passes through a slot in the side of the cone, and the wall of the outlet pipe 5 may be. slotted. Separators may be arranged in pairs with their outlets 5 entering a common shaft.

Filed: 1936-12-21
Abstract: 475,706. Automatic control systems; switching systems. BRITISH THOMSONHOUSTON CO., Ltd. Dec. 21, 1936, No. 35071. Convention date, Dec. 21, 1935. [Class 38 (iv)] Temperature.-To ensure complete heating of a furnace charge without waste of energy, the lengths of successive heating cycles or of the heating or cooling parts thereof are continuously compared by means, operatively associated with means for automatically turning the heat on or off at given temperature limits, which give visual or aural indication as soon as the lengths become equal. As applied to a furnace with electrical heating elements 12 and a temperature controller 14 supervising a main contactor 18, a relay 63 is energized each time the furnace circuit is closed. A relay 60 and a pawl actuating magnet 49 are thereby energized against springs tending to restore the opening of contactor 18 and relay 63, the relay 60 energizes a contact 43 on a step-bystep switch 20 and the pawl moves this and a companion contact 44 to the next stationary contact. These contacts are in two banks of which those engaged by the contact 43 are interconnected in groups of three to leads 45, 46, 47 and every third contact of those engaged bv the contact 44 is connected to a lead 48. The leads 45 ... 47 are connected to the timing mechanism so that in successive cooling periods (1) the coil 28 of a motor is energized to drive a cam-shaft from zero a distance proportional to that period ; (2) the coil 29 of the motor drives the cam-shaft back through a distance proportional to the next period (this distance is initially greater than the first distance) ; (3) the coil 28 is energized through a switch 36 opened in the zero position and the cam-shaft to reset the shaft to zero. When the periods are equal and resetting does not occur at (3), the circuit of an alarm is completed through the contact 43, lead 48 and a switch 38 closed in the zero position of the cam-shaft. The cam-shaft may carry a pointer co-operating with a frictionally driven pointer to show when the time periods of successive cycles agree.

Abstract: 891,716. Forming fibres into mats and webs. AMERICAN AIR FILTER CO. Inc. Feb. 17, 1958, No. 35544/61. Divided out of 891,715. Classes 120(1) and 120(3) [Also in Group VIII] A sheet-like filamentous mat comprises a plurality of overlying layers of filamentous material in which at least one of the layers includes a succession of transversely spaced, substantially straight non-crossing multi-filament collected cords and a succession of transversely spaced substantially straight non-crossing individual monofilaments. The multi-filament collected cords and monofilaments of one layer may lie generally in crossed relationship with the multi-filament collected cords and monofilaments of an adjacent layer. The mat may include a binder for the filamentous material. The filaments may be of glass. One face of the mat may be provided with a backing ply composed entirely of monofilaments. As shown in Fig. 1 the mat comprises multi-filament collected cords 2, 3 and 4 and individual monofilaments 5. As shown (Figs. 4 and 5) apparatus for making the mat according to the invention comprises a drum 10, journalled for rotation and driven by belt 12; a glass furnace 13 supported for reciprocation along rails 15; a group of spinnerets (not shown) on the bottom of furnace 13 for feeding glass filaments to the drum; filament collection wheel 18 supported by bracket 17; and horizontal discharge pulley 20. The apparatus comprises two additional glass furnaces 23, 23<SP>1</SP>, stationarily mounted beyond one end of drum 10 and cooperating with collector wheels 18<SP>1</SP> and 18<SP>11</SP> and discharge pulleys 20<SP>1</SP> and 20<SP>11</SP>. In operation the furnace 13 is reciprocated while drum 10 is rotated a multiplicity of times during each traverse of the furnace; filaments 16 from the furnaces are fed to the respective collector wheels which form them into cords 19 which are fed to the respective discharge pulleys and thence delivered to the rotating drum. A portion of the filaments 16<SP>1</SP>, from furnace 13 are fed directly to the periphery of drum 10. There is thereby built up on the drum, during successive traverses of the furnace, a cylindrical condensed mat 21 having a succession of layers each containing a plurality of helical turns of multi-filament collected cords and individual monofilaments. The mat is thereafter slit axially and removed from the drum. After removal from the drum, the mat may be stretched axially (Fig. 7) to form an elongate expanded thickness web 29 which is conveyed by conveyer 30 through a bath of binder liquid 32 wherein it is compressed by roller 33 and then passes over suction device 35 and through heater 37 and is wound on roll 38.
