Title: Improvements in switching arrangements in automatic telephone systems
IPC: H04Q1/48
Filed: 1937-07-19
Abstract: 495,216. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. July 19, 1937, No. 19945. Convention date, July 21, 1936. [Class 40 (iv)] In a system employing junctions which are inductively coupled at each end, the calling signal over a junction consists of two inductive impulses of opposite polarity, the order of the impulses being determined by whether it is an ordinary or a toll call. Upon seizure of the junction, relay R1 energizes followed by sluggish relay R2, and in the case of a toll call, relay R5 energizes at the same time as R1 and is disconnected by R2. Thus direct current of one polarity or the other flows through the primary of the transformer TR1 during the operating period of R2, and gives rise to two inductive impulses. In the case of an ordinary call, polarized relay R11 closes first contact a, connecting up R12 which locks, and then contact b, connecting up R13 which locks and operates R15. The latter repeats the calling signal, prepares R16 for receiving A.C. impulses and disconnects R12. In the case of a toll call, contact b is closed first and discriminating. relay R14 energizes and locks, after which the closure of contact a operates R12, and the latter connects up R13, R15. Numerical impulses are sent over the junction by R4 as A.C. impulses and are received and repeated by R16, R13, R17. Upon reply, an A.C. impulse is sent back over the junction by R18 and is received by R3. Upon release at the calling end, a long A.C. impulse is sent during the release period of R2 to bring about the relapse of sluggish holding relay R18.

Abstract: 773,998. Testing tyres. DUNLOP RUBBER CO., Ltd. June 21, 1955 [July 8, 1954 ],No. 19968/54. Class 144 (1). [Also in Group XXXVI] An apparatus for detecting and indicating tyre "thump " comprises an acoustic box 11 mechanically connected to the support 2 of a tyre under test and housing a microphone 16 to detect sounds generated in the box by vibration forces set up when the tyre is rotated in contact with a smooth hard surface, the microphone being connected via an amplifier 18 to an electrical indicating unit. The apparatus may be portable, the acoustic box being mounted on the wheel stub axle, or, as shown, may comprise part of a machine having a frame 1 supporting a pivoted beam 2 on which a tyre carrying wheel 5 is rotatably mounted. The tyre is driven by a drum 21 which is carried by an arm 19 pivoted to the frame 1 and is driven by a variable speed motor 26, the arm 19 being moved about its pivot 20 to raise and lower the drum, into and out of contact with the tyre 6, by a motor-driven cam 29. A stop 39 on the frame 1 holds the beam 2, and thereby the tyre 6, out of contact with the drum 21 when the latter is lowered by the cam 29. The tyre 6 is uninflated when under test and the beam 2 is loaded by an adjustable weight 7 to provide a predetermined deflection of the tyre when in contact with the drum 21. The beam 2 is connected at its outer end to the frame 1 by a motorcar shock absorber 37. The acoustic box 11 is rigidly mounted on the beam 2 by a post 15 and comprises two cylindrical halves each closed at one end and separated at their open ends by a diaphragm 14, the microphone 16 being resiliently mounted in the sound-proofed lower half of the box. Fig. 2 shows the circuit whereby the amplifier output is doubly rectified and smoothed to provide a steady " thump " indication on the meter 48. Additionally, signal lights may be provided to indicate thump characteristics above and below a predetermined limit. Further, to locate the cause of the thump, a flash tube may be arranged to fire once per revolution of the tyre, at the peak of the thump sound wave, to permit stroboscopic reading of one of a series of marks on the wheel carrying the tyre.

Abstract: 782,394. Batteries. ACCUMULATORENFABRIK AKT.-GES. July 14, 1955 [July 14, 1954], No. 20414/55. Class 53. In a gas-tight accumulator, particularly an alkaline accumulator, having the positive and negative electrodes spaced apart by one or more separators which are pervious to liquid but impervious to gas bubbles and also having part of the electrodes in contact with a gas space in the container and the electrolyte held by capilliary action in the separators and the pores of the electrodes, the positive electrodes contain both positive and negative active material and the capacity of the positive active material alone is less than or at most only slightly greater than that of the negative electrodes whilst the capacity of the mixed positive and negative active material in the positive electrodes is so much greater than that of the negative electrodes that with excessive discharge of the accumulator oxygen is generated at the negative electrodes while the positive electrodes have still not given up their whole quantity of chaige. The positive electrode may be arranged to have a greater charge than the negative electrode at the moment of sealing by charging the accumulator whilst in the open condition and filled with electrolyte to the full extent of both positive and negative electrodes, emptying the electrolyte and sealing the container. The accumulator may then be discharged as far as complete discharge of the negative electrode. Alternatively, the accumulator whilst in the open condition and filled with electrolyte may be charged to the full extent of both positive and negative electrodes and then discharged at most as far as the complete discharge of the negative electrodes, the electrolyte then being emptied out and the accumulator sealed. Each positive electrode may be formed as a double electrode as described in Specification 741,305, [Group XXXIX], and a single negative electrode may be used with one or a pair of positive electrodes as described in Specification 755,547. Specification 769,784 also is referred to.
