Title: System for detecting the failure of the insulation of electric cables
Filed: 1955-01-24
Abstract: 765,062. Indicating faults. SPECIALTIES DEVELOPMENT CORPORATION. Jan. 24, 1955 [March 1, 1954], No. 2035/55. Class 38(5) Indication of faulty insulation in a cable comprising a conductor 10, insulation 11, shield 12 and insulation 13, is obtained by connecting one end of the conductor 10 to an energy source, connecting an indicator 15 between shield 12 and the other side of the source and connecting the latter side of this source to a second source, the other side of which is earthed. The two energy sources may comprise a battery 21, the indicator 15 being connected to an intermediate point thereof. Failure of the insulation 11 completes the circuit 10, 12, 15 and left-hand part of the battery, while failure of the insulation 13 causes the shield 12 to be earthed and completes the circuit 12, 15, right-hand part of the' battery and earth. A load such as a relay having a coil 22 may be inserted between the conductor 10 and the battery 21, and a normally open switch 26 between the other end of conductor 10 and earth. The coil 22 is energized to operate the relay only by application of the full battery potential which occurs when switch 26 is closed or when the conductor 10 is earthed by disruption of the cable. On failure of insulation 11 the coil 22 is subjected to only part of the full potential which is insufficient to operate the relay. On operation of the indicator 15, normally closed swit.ches 27 or 28 may be opened to cut out coil 22. The indicator may be connected in the circuit by a relay-operated switch (Fig. 4, not shown), the relay having a high impedance to limit the current flow in the coil 22. Specification 759,808 [Group XXI] is referred to.

Filed: 1966-01-17
Abstract: 1,111,755. Transistor gain control circuits. MARCONI CO. Ltd. 12 Oct., 1966 [17 Jan., 1966], No. 2056/66. Heading H3T. In a cascade wide-band tuned amplifier, in which the gain is varied by varying the bias on the input transistor A1, this transistor is shunted by a resistor A10 between collector and earth, so as to reduce the changes in the current through the output transistor A2. This reduces its changes in output impedance as the gain is varied and so prevents distortion of the frequency response. As shown, the amplifier comprises three stages, the gains of transistors A1, C1 in the first and last stages being varied; these stages are tuned in the region of the lower frequency limit of the pass-band while the second stage is tuned in the region of the upper frequency limit.

In one example, Fig. 1, the spacing means comprises a plate 18 pivoted at 19 to the top of a table 10 and having an inclined extension 20 which swings downwardly to contact the table when the plate 18 is raised. A spring biased latch finger, Fig. 2 (not shown), is disposed to engage the extension 20 and hold the plate 18 and its associated members in an inclined position until released by a lever 23. Operation. With the plate 18 &c. in raised position a shirt is laid, button strip down, on the top of the table and a collar form 13 in a depression 12 in the table is contracted by means of a foot pedal (not shown) mounted on a lever 15. The collar is dressed on the form 13 and the button strip is aligned by means of a light 33. The operator then releases the foot pedal to expand the form 13, and disengages the latch by means of the lever 23. The plate 18 drops to contact the edge of a rectangular cardboard stiffener 24 which has been laid on the shirt. The arms 25, 26 and wings 27, 28 are swung outwardly to the position shown in Figs. 1 and 4. The lower sleeve portions hang downwardly over flipper arms 29, 30 pivoted to the sides of the table. The arm 29 is swung upwardly to throw the right sleeve and cuff to the position shown in Fig. 4. Arm 30 may be moved simultaneously and the two arms 29, 30 are then returned to idle position (Fig. 1). Wings 27, 28, and then arms 25, 26 are swung inwardly to fold the shirt to approximately the width of the plate 18, the tail of the shirt being given an "S" fold preferably before movement of the arms 25, 26. The folded shirt is then encircled by a paper strip housed in a slot 31 in the table. The operator releases the collar form and raises the plate 18 etc. before slipping the shirt off these elements. Modification. Fig. 3 shows a simplified form made from cardboard and bendable along the four lines X. The rearwardly extending edge of the portion 18<SP>1</SP> can be slipped under the rear edge of the collar for stability in starting the folding operation.

Class 73 A web 1 of transparent patch material is fed by a feed roller 4 via a reversing roller 3 to a cutting device 5, 7 which cuts the web only partially, e.g. by perforations, and the web then passes between pull-and-brake rollers 10, 11 which tension the web and advances it between a suction roller 12 and a co-operating pressure roller 13. The suction roller 12 rotates faster than the travelling speed of the web imposed by the rollers 10, 11 and consequently tears its leading perforated section off the web while the next section still remains clamped between the rollers 10, 11. The detached patch then passes between roller 12 and a suction roller 14 together with an envelope blank 16 for application to its window. Since the patch is not detached until immediately prior to its application to the envelope, tension in the web is maintained.

[Class 106 (v)] [Also in Group XXVI] A device for delivering measured quantities of liquids, more particularly viscous liquids such as oil, comprises a measuring chamber 1 through the lower end of which passes an operating member 2 carrying a valve 10 and piston 3 so that on upward movement of the member 2 the valve closes the chamber-inlet 6 and the piston thereafter forces the measured quantity of liquid through a passage 4 in the operating member to an outlet nozzle 25 at its lower end. The piston comprises an annular disc 3 of rubber or other material clamped between metal flanges 16 and 17 having outer portions of frusto-conical form. The disc makes line contact with the wall of the chamber 1. Within the upper part 14 of the operating member is a valve stem 9 having at its upper end the valve 10 controlling the inlet 6 and at its lower end a valve 12 urged by a spring 15 into engagement with a seating 13 to prevent passage of liquid through the operating member. The upper end of the chamber is formed as a socket to receive the neck of an inverted container. In operation as the member 2 is moved upwardly against a spring 19 by means of arms 24, the valve 10 closes the inlet 6 and further movement raises the seating 13 away from the valve 12 and the piston forces liquid through the member 2 to the outlet 25. The amount of liquid delivered may be varied by controlling the stroke of the operating member. Dripping is prevented by a flared outlet end 29 and by an annular channel 28 into which any liquid remaining in the nozzle is withdrawn by suction produced by the return movement of the piston.
