Patent GB-489070-A (GB)
Title: Improvements in or relating to telephone and telegraph exchange systems
IPC: H04M11/06
Filed: 1937-07-30
Abstract: 489,070. Manual exchange systems. STANDARD TELEPHONES & CABLES, Ltd. (Western Electric Co., Inc.) July 30, 1937, No. 21184. [Class 40 (iv)] A cord circuit has a key for changing over from a path through a repeating coil for telephony to a direct path for teleprinter communication. The cord circuit may also include a teleprinter. For telephony, switch MN, Fig. 2, is in its upper position and the talking circuit between two connected subscribers includes repeating coil RC1 .. RC4. The wanted party is rung by current from generator G over key RK and the ring conductor to ground at the substation. When the subscriber replies, the closure of the loop releases differential relay R2 and extinguishes lamp 7. For teleprinter communication with no teleprinter in the cord circuit, the calling substation, Fig. 1, closes key PS and the operator throws keys THRU and MN, cutting out the repeating coil RC1 .. RC4 and completing a direct-current circuit through the cord including a 48-volt source the motor-generator set MGS of which is started by relay MGC whenever a plug is inserted. The substation shown in Fig. 3 is adapted for unattended use, e.g. to record a message when the subscriber is absent. When attended, the throwing of key SK starts the teleprinter motor MO and operates relay 4 which locks to maintain the operation. Centrifugal contacts 6 connect the teleprinter apparatus across the loop. When unattended, the motor is started by the operator throwing key USK connecting ringing current over the tip conductor to operate relay 5. The motor is stopped by sending a special signal which causes the operation of bar PB. Recall signals may be sent by operating the switch hook with switch PS restored, thus intermittently unbalancing relay R1 and flashing lamp 7. When the cord circuit is provided with a teleprinter, key TK is thrown to operate relay 8. With key THRU normal, the operator's teleprinter is connected to the calling line only and with THRU thrown is connected in the series circuit through the cord. If the line circuit remains open for a considerable time. slow-release relay SR is short-circuited and released by line relay LR and operates magnet AM to prevent the teleprinter from " spinning " indefinitely. The operator may be recalled by operating key PS, Fig. 1, or RCK, Fig. 3, intermittently. In order that both subscribers may re-call at the same time, when the calling loop is opened and relay R1 operated relay R3 completes an alternative loop to the called line through an equivalent resistance. Cam 55 is employed to send a timed release signal when plug 3 is connected to a junction leading to a central office.

Abstract: 583,451. Phase difference measurements. BRITISH THOMSON-HOUSTON CO., Ltd Oct. 30, 1944, No. 21199. Convention date, Oct. 28, 1943. [Class 37] A phase-comparison arrangement in which both input circuits are grounded, comprises lagging and leading phase-shifting networks across each input circuit, centretapped decoupling impedances connecting the lagging output terminal of each network to the leading output terminal of the other, square-law detectors for each centre-tap voltage, and means for subtracting the detected voltages. One input 1, 1<1> is applied to a phase-retarding network 7, 5 and to a phase-advancing network 8, 6, and the other input 2, 2<1> to a phase-advancing network 8, 5 and a phase-retarding network 6, 7. The output terminal 9 is connected to the output terminal 12 through resistances 13 the centretap of which is connected to a detector 17. Similar connections are made from output terminals 10, 11 to a reversely-poled detector 18, the detectors having condenser-shunted load resistances 19, 20. D.C. voltages of opposite sign are developed across the condensers 19, 20 and their difference, available between the terminal 21 and earth, is proportional to the sine of the phase angle between the inputs at 1, 1<1> and 2, 2<1>. Preferably the reactances 7, 8 are equal to each other and to the resistances 5, 6, so that the phase shifts are of 45 degrees. Capacities between leads &c. may be tuned out by inductance coils 22-25.

Title: Apparatus for the filling of containers,especially tubes

Filed: 1964-05-27
Abstract: 1,016,661. Bottling. DRUK-PAK A.G. May 27, 1964, No. 21830/64. Heading B8T. A container filling and stoppering apparatus includes a work cylinder 1 and piston 8 supplied through passages 6 and 7 with pressure medium whereby a piston 15 in a dosing or measuring cylinder 14 is reciprocated. When the dosing piston 15 is driven upwardly filling material is drawn into its cylinder from a line 61, passages 23, 18 and past a normally closed valve 19 in a head 16. On the downstroke the filling material is forced through passages 17 in the head whereby a valve 25 is urged upwardly against the action of a spring 30 and filling material is allowed to flow into the container 56 past a stopper. Upward movement of the valve 25 is effected by the pressure of filling material acting upon a piston 24 of the valve. As shown, the valve in its lowermost position seats on a washer 26 above the container opening. On further downward movement of the piston 15 a ram 29 forces a stopper plunger downwardly to force the stopper into the container opening. A normally closed valve 35 is opened when the piston reaches a lower position whereby filling material in the cylinder 14 is fed back to the line 61 via passages 31, 37. The container 56 is mounted on a plate 49 resiliently supported by springs 51 about columns 50 supported on a table 48 reciprocated vertically by a fluidoperated piston and cylinder motor 68, 69. Thus the container opening is brought into sealing contact with the head 16. Before the filling step the container interior is connected to a vacuum chamber 57 via a normally closed valve 39 in the head and passages 41, 42 and 54. The valve is opened by a cam 45 secured to the table 48 by a pedestal 47. After the container stopper is forced home the valve 39 is again opened so that surplus filling material is drawn into the vacuum chamber 57. The stroke of the work cylinder is adjusted by a piston 4 screwed into a cover 2. The dosing cylinder 14 has a piston-like collar 13 slidably received in a stroke cylinder 11, and downward movement of the cylinder 14 is controlled by a throttle valve 63.

Abstract: 759,698. Electric copying machines. SOC. AUTOMATA. Aug. 29, 1952 [Aug. 31, 1951], No. 21840/52. Class 40(1) In a copying machine wherein a feeler exploring a pattern, controls, through contacts and relays, the co-ordinate driving means of both the cutter and feeler, the various circuit control parts are grouped into units disposed on appropriate parts of the machine and inter-connected by lug and socket connections which may be permitted to allow various ways of pattern exploration. Fig. 2 shows a copying lathe in which the pattern 17 fixed to the lathe bed is explored by a feeler unit F carried by the transverse slide 15 on which the tool 16 is also mounted. Electromagnetic reversible clutch units K1-K2, K3-K4 determine transverse and longitudinal feed in known manner and are fed from a mains unit N under the control of a relay unit R and a switch unit B which may be incorporated in one unit and are secured to the longitudinal carriage 18. As disclosed in Specifications 759,697, 759,699, the feeler 1, Fig. 1, is mounted for limited universal movement and operates contacts 3, 4, 5, respectively, at successively increasing deflections of the feeler from its neutral position. A safety contact 6 is operated by excessive feeler deflection to stop the machine. The contacts 3, 4, 5 through relays R1...R4 control the clutch units K1K2, K3-K4 which each include windings, for forward and reverse movement, transverse and longitudinal, of the feeler as described in Specification 759,699. Figs. 3-9 inclusive (not shown) illustrate the various ways of interconnecting the four clutch coils to the contacts of the relays R1...R4, to effect exploration of the pattern longitudinally from right to left, or left to right for both external and internal copying and also for transverse copying inwards or outwards.
