Title: An offset control system for traffic signal
IPC: G08G1/081
Filed: 1966-07-25
Abstract: 1,086,664. Road traffic signals. TATEISI ELECTRONICS CO. July 25, 1966 [July 30, 1965], No. 33394/66. Heading G4Q. A master controller supplies clock pulses which can vary between 40 and 120 per second, split and offset selection signals, and a synchronizing pulse transmitted once per cycle, and the local controller is provided with means for counting the clock pulses and for altering the counting means to change the cycle length slowly when a new offset is required. The counting means comprises a scale of six counter (1C1, Fig. 1, not shown) feeding a further counter (1C2) feeding two decimal counters (2C1 and 2C2, Fig. 2, not shown). The final counter normally produces an output (on line 3) after every 4800 pulses and this output starts the green period. The decimal counters are connected to pinboards (210-213 and 220- 224) which can be set manually and two of which are selected by the split and offset signals from the master controller to give a required split signal (on terminal 4) which terminates the green period at a desired count and an offset signal (on terminal 202) which should coincide with the synchronizing signal. The synchronizing signal lasts for 144 clock pulses and is applied (over line 401, Fig. 3) to a flip-flop (3F1) to which the local offset signal is also applied' (over line 202). If the two signals coincide the flip-flop remains set and operation proceeds normally. If the synchronizing signal is late, due to a change in offset, and output from the flip-flop (on line 301) stops the decimal counters, and the output of the further counter (1C2) is passed to a fifth counter (3C1, via line 102). If this fifth counter fails to count ten before the synchronizing pulse arrives the system is now synchronized and normal operation is resumed. If it does complete its count, the decimal counters resume counting and an output from the first decimal counter passes to a sixth counter (4C1) which is used to determine whether the synchronizing pulse is delayed more or less than 50% of the cycle time; according to which answer is given the scale of the further counter (1C2) is altered from its normal eight to either seven or nine so that synchronization is achieved in the minimum number of cycles.

Title: Improvements in or relating to yarn winding
Inventor: HALKYARD HAROLD
IPC: B65H59/30
Filed: 1954-11-18
Abstract: 802,075. Thread tensioning devices; stop motions. BRITISH CELANESE, Ltd. Nov. 16,1955 [Nov. 18, 1954], No. 33430/54. Class 120(2) A method of winding yarn in which a package is driven at a constant angular speed comprises tensioning the yarn on its way to the package by constraining it to follow a zig-zag path through two intermeshing sets of horizontal bars in which the total angular deflection of the yarn  is limited by a maximum, and diminishing the maximum by moving both sets of bars as the package increases so as to diminish the tensioning effect on the yarn. A delay may be provided between the start of winding and the instant when the maximum angular deflection of the yarn starts to decrease. Bars 21 are carried on frames 17, 18 pivoted near their upper ends about horizontal axes, the frames 17, 18 being connected, preferably by light chains 25, 27 to the arm 9 carrying the traverse guide 6, so that as the package 7 grows the chains are pulled and the tension device 4 assumes a more open position. A stop member 35 having a triangular tip 36 and a slot 37 is held in position with the tip 36 between the lower ends of the frames 17, 18 by a screw 38 adjustably mounted in the slot 37, to set the initial degree of opening of the two sets of bars 21. A mechanical stop motion operable if the yarn breaks or slackens consists of a light wire guide 5 held vertical by the tension of the yarn, which when the yarn breaks or slackens strikes a pin 45 on a rotatable disc 44, which by its rotation sets in motion an 'arm 47 having at its end a steel pin 49. The motion brings this pin 49 under the influence of a permanent magnet 50 so that it is jerked towards the magnet 50. By this action a rigid rod 48 engages a toothed wheel 51 which rotates while winding is taking place. Thus the rotation of the wheel 51 acts to pivot the quadrant arm 13 about a pivot point 14 and activates the machine stop motion (not shown). The Provisional Specification discloses an electrical stop motion in which the guide 5 engages a mercury type switch when the yarn breaks to complete an electric circuit and thus stop the machine.

Title: A control signal generator for diversity reception
IPC: H04B7/08
Filed: 1963-08-23
Abstract: 991,446. Diversity reception systems. NIPPON ELECTRIC CO. Ltd. Aug. 23, 1963 [Aug. 29, 1962], No. 33477/63. Heading H4L. In a control circuit for deriving control signals dependent on noise or signal strength for controlling the combination or selection of the respective frequency modulated signals in a diversity reception system, the channels are switched in turn to the input of the control circuit and similar switching takes place at the output of the control circuit. When an individual control circuit is used for each channel the characteristics of the control circuits must be identical and this disadvantage is avoided by the use of the arrangement described. As shown in Fig. 2, two input signals which may be I.F. or video signals at terminals 31A, 31B respectively are supplied to a signal combiner 13, combination or selection being controlled by the common control circuit 30. The input terminals are also connected to band-pass filters 35A, 35B respectively, deriving noise components which are sampled alternately by a switch 36, controlled by a square-wave generator 43, and supplied to a noise amplifier 37. The output of the amplifier 37 is detected at 38 and fed back through a low-pass filter 45 and A.G.C. circuit 46 to control the gain of the amplifier 37 in accordance with the mean value of the noise levels from the respective transmission paths. The output of the detector 38 is also supplied via a band-pass filter 39 to a circuit 40 which expands the control signals to compensate for the compression taking place in the amplifier 37, the output of the expander being amplied at 40 and supplied via the switch 42 to control the signal combiner 13. The switch 42 is controlled by the square-wave generator 43 via a delay 44 and is followed by low-pass filters so that continuous control signals are supplied.

Title: Improvements in or relating to automatic telecommunication exchanges
Inventor: HARTLEY GEORGE CLIFFORD
IPC: H04Q3/52
Filed: 1959-10-02
Abstract: 910,458. Automatic - exchange systems. STANDARD TELEPHONES & CABLES Ltd. Sept. 30, 1960 [Oct. 2, 1959], No. 33481/59. Class 40 (4). In an exchange of the type described in Specification 794,812, each of the non-numerical switching stages comprises a co-ordinate array of PNPN diodes. To set up a connection between an A ' frame inlet and a 'C' frame outlet (Fig. 4), the inlet is marked by application of +V1 (e.g. 60 volts) by operation of relay H (not shown) via resistance R1 in the first link, and the outlet by - V3 (e.g. - 5 volts) via R2 (e.g. 100 ohms) in the final link, +V2 (e.g. +35 volts) being connected as a clamping voltage to the A ' frame inlet. The route selector chooses an available route (indicated by operated relays T (not shown) in the intermediate links) and then closes its contacts TA to apply- V4 (e.g. -45 volts) to the second link of the route. The diode DA breaks down, whereupon the route selector closes TB, and then opens TA and closes TC to break down DB and DC, respectively. The rectifier in the final link then conducts, TB and TC are opened and the route selector is released. The voltage at the A ' frame inlet drops to near - V3, and the whole connection is at a low negative potential which marks the second and third links busy. Testing and marking of the second or third link is performed by the circuit of Fig. 5. Terminal GM is grounded on all second links which can be reached from the ' A ' switch concerned, and on all third links which can connect to the ' C ' switch concerned by group marking relays (not shown). Transistor TR1 conducts if the link is busy, and TR2 is blocked; conversely TR2 is not blocked for an idle link. Thus relay T is operated in all free links which can provide a path betweeu the marked inlet and outlet. T locks up and marks terminal M to indicate a free link. When the route selector chooses the route to be used it connects the switching voltage over the terminals M of the links concerned. Specifications 813,862 and 910,459 also are referred to.

Title: Timing control for fuel pumps
IPC: F02M41/14
Filed: 1957-10-28
Abstract: 857,295. Fuel injection pumps. ROOSA, V. D. Oct. 28, 1957 [Nov. 15, 1956], No. 33509/57. Class 102(1). A fuel injection pump in which the timing is varied in accordance with the pump output comprises an injection pump 14, Fig. 1 fed from a feed pump 27 both pumps being driven in accordance with the engine speed through a shaft 13. The injection pump 14 Fig. 3 comprises a rotating cylinder block 17 housing inwardly acting pistons 19 reciprocated by an adjustable stationary cam 11. The cam is normally urged into retarded position by a spring loaded piston 39 and the timing is advanced by fuel acting on a loose fitting piston 40 which allows leakage past it when the timing is subsequently retarded. The feed pump 27, Fig. 1 delivers fuel through passages 44, 45 groove 48 in the distributer 15, passage 59a in a valve 50, passages 52, 53 to the inlet passages 25 in the distributer 15 and via an axial passage 24 to the injection pump from where fuel is delivered to the engine cylinders via passages 24 and 26. The valve 50 is provided with an axial slot 71 co-operating with passages 53 and a helical slot 70 which co-operates with passages 64, 63 and circular groove 61 to permit flow of fuel via passages 60, 59 and 56 to the rear of piston 40. Both slots 70 and 71 are in communication with passage 59a in the valve 50. The valve 50 is axially adjustable by a tapered pin 76 and is rotated by hand or automatically in response to the load on the engine. In operation, assuming the motor is operated at full speed and high load, fuel delivered by feed pump 27 passes to the injection pump through passage 59 and slot 71 of the valve 50, helical slot 70 being out of register with the port 64. Under these conditions the timing is fully retarded. If the load is now removed from the engine the valve 50 is rotated manually or automatically to reduce the fuel flow to the engine and the helical slot 70 is brought into register with passage 64 thus allowing flow of fuel to the piston 40 to advance the timing. If there is a subsequent lowering in speed the pressure of the fuel delivered by the feed pump is reduced and a non- return valve in the passage to the piston 40 closes and allows the cam to return to a retarded position. This latter condition also exists if the valve 50 is turned to increase the flow of fuel to the injection pump. U.S.A. Specifications 2,641,238 and 2,660,992 are referred to.

Filed: 1929-11-05
Abstract: 348,505. Synchronizing dynamoelectric machines. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Nov. 5, 1929, No. 33618. Convention date, Nov. 9, 1928. [Class 38 (iv).] A motor, acting as synchronoscope and having its two elements respectively connected to the generator to be synchronized and the a.c, network, and having its motor arranged to influence the speed adjusting motor of the governor of the prime mover in accordance with frequency variation, operates a device giving a time interval between successive energizations of the speed adjusting motor which is an inverse function of the difference between generator and network frequencies, the intervals disappearing at a comparatively great frequency difference. Thus the mean speed of the adjusting motor is a maximum at a great frequency difference and is reduced to zero when the frequencies are the same. As shown in Fig. 1 the synchronoscope motor c closes, once in each revolution, a contact i or k in the circuit of the governor adjusting motor e. The contact is accelerated and held by magnetic means and opened by the restoring springs m against a damping disc o when the springs overcome the magnetic force. Fig. 2 shows a quick-acting rolling-sector regulator, operated by the motor c in a similar way, and controlling the magnitude and direction of the voltage applied to the armature of the motor e. The Specification as open to inspection under Sect. 91 (3) (a) also described a synchronoscope motor operating a centrifugal switch and a reversing switch, the former controlling resistance in the field circuit of the governor adjusting motor, and the latter controlling the direction of its movement. This subject-matter does not appear in the Specification as accepted, but in Specification 348,610.

Title: Improvements in the manufacture of cellulose triacetate filamentary materials
Inventor: GROOMBRIDGE DENIS WILLIAM
IPC: D01F2/28
Filed: 1954-11-23
Abstract: Cellulose triacetate filaments are made by extruding a solution of the triacetate in methylene or ethylene chloride, or in a mixture of either chloride with methyl or ethyl alcohol containing up to 10 per cent by volume of the alcohol, into a liquid coagulant comprising carbon tetrachloride, trichlorethylene or a monohydric alcohol containing 1-4 carbon atoms in the molecule, or a mixture of two or more of these liquids, the temperature of the coagulant being above 0 DEG  C.  When the coagulant is an alcohol containing 3 or 4 carbon atoms, the methylene or ethylene chloride content of the coagulant in the spinning zone may be stabilized at about 20-25 per cent by volume, but with the other specified coagulants is preferably kept down to 5 per cent or less.  The concentration of cellulose triacetate in the spinning solution should preferably be at least 15 per cent and the temperature of the solution should be below about 65 DEG  C. and especially below about 40 DEG  C.  The temperature of the coagulant is preferably below about 40 DEG  C. and is advantageously about 5-25 DEG  C.  The takeup speed/extrusion speed ratio may be 0.2:1 to 2:1.  In an example, a 24.8 per cent solution of cellulose triacetate in a 93/7 parts by volume methylene chloride/methyl alcohol mixture is extruded into trichlorethylene at 15 DEG  C. in an upward spinning device described in Specification 720,187.  The flow rate of the trichlorethylene is 500 c.c. per minute and the yarn produced is drawn from the spinning tube at 40 metres per minute. After leaving the setting tube as much as possible of the adherent liquid trichloroethylene is removed from the yarn as liquid and the remainder by heating the yarn to about 100 DEG  C.
