Title: Improvements in systems of control for electrically operated lifts
IPC: B66B1/36
Filed: 1937-05-04
Abstract: 493,322. Control of A.C. motors ; dynamo - electric braking. EXPRESS LIFT CO., Ltd., and WELLS, L. E. W. May 4, 1937, No. 12678. [Class 38 (iii)] In a lift-controlling system according to Specification 458,380, the step-bystep switch B which determines the extent of energization of an eddy-current brake EB is energized under the control of a vibratory type relay SV operating at a frequency independent of the supply voltage. When a relay C is operated at the first of the predetermined points a relay M is operated to energize a relay N which de-energizes the relay SV. The contact SV1 is released and operates to the right, de-energizing the coil of the switch B and remaking the circuit for the coil of the relay SV. Then the relay SV vibrates and the coil B is intermittently energized to step the contact bank B2 and adjust the energization of the brake EB until the second predetermined point is reached by the lift cage whereupon the relay C is operated to deenergize the relay M which energizes the coil SV and stops the relay SV from vibrating. Thus the movement of the switch B is stopped. The armature of the relay SV may be of the type shown in Fig. 2, of Specification 289,602, [Class 38 (ii)].

Title: Sounding apparatus for determining the surface and bottom levels of a liquid from a point above it
IPC: G01F23/44
Filed: 1927-05-14
Abstract: 280,809. Siemens - Schuckertwerke Ges., Steiner, L., and Gutmann, V. May 14, 1927. Indicators, electric.-A sounding device, more particularly for determining the level of brine and oil layers in an oil sounding, comprises a plummet carrying a switch which is actuated by a float when it reaches the liquid. A cable drum 4 carries a two-conductor cable 5 which is carried past a measuring wheel 12 and then over a roller 6 into the bore hole 10. One end of the drum is provided with a band brake with lever 17. One end of the cable 18 is connected to the terminal box 20 and to slip rings, and a pocket lamp battery 26 and buzzer 27 are also connected to the terminal box. The other end of the cable is connected to a plummet 29 enclosing a frame 30 carrying a cork float 33. The rod 31 carries a mercury switch 34 adapted to be operated by the float. A rod 39 carries a foot plate 40 and a cone 38, so that when the plate 40 strikes an obstruction the cone 38 actuates the bell crank lever 32, 37 and lowers the float, thereby actuating the mercury switch. The position of the liquid level is determined by the rising of the float, which actuates the switch to complete the circuit and sound the buzzer, while the bottom of the bore hole is determined by the stopping of the buzzer. The depths are read on the counter 14. A modification (Fig. 5, not shown) employs a hollow cylindrical float, pivoted eccentrically, to actuate the mercury switch. In another form (Fig. 6, not shown) the float and mercury switch may be combined in a single flow body of glass, and in another form (Fig. 7, not shown) the mercury switch is placed on a suspended body having a float at one side so that the body is tipped when the float is immersed. In Fig. 8, the float 72 is guided in the sleeve 73 and carries the mercury switch 74. The two contacts are at one end of a closed tube, and the circuit is made or broken when the tube in inverted. In Fig. 10, the electrodes 77, 78 are connected to the conductors 35, 36, and the float casing 79 is movable longitudinally on the plummet 29. The liquid 81 is a good conductor. During lowering, the casing 79 rests on the float until it reaches the liquid, when it stops and the electrodes 77, 78 become immersed in the liquid 81 and the circuit is completed. The plummet is then repeatedly raised and lowered in the oil until the liquid 81 has been expelled and replaced by oil, so that the circuit is broken. On further lowering to reach the level of brine, the circuit is again completed. The device may be used to measure the conductivity of the liquid by connecting a measuring device in place of the buzzer 27, Fig. 1.

Title: Fault detecting arrangements in pcm telecommunication systems
IPC: H04B17/40
Filed: 1973-03-19
Abstract: 1394793 Repeater fault locating SIEMENS AG 19 March 1973 [30 March 1972] Heading H4R In a fault locating system for the repeaters of a pem communications system, at a transmitting station 1 a first generator 15 feeds the line with a test pulse pattern comprising a synchronizing word composed of pulse code element pairs "11" and "00" which are each interposed in an alternating sequence between an equal number of modulatable pulse code elements. The station 1 also includes a modulator 3 which operates on the modulatable elements of the test pulse pattern and which is controlled by a rectangular waveform generator 2 the frequency of which can be set to the characteristic frequency of a band pass filter 11 of the repeater station 8 which it is desired to test. Detection of that frequency in the transmitted test pulse pattern at the repeater causes a looping of the go and return paths at that repeater and return of the test pulse pattern to a comparator 4 where the synchronizing word is compared with a word generated in 16, which is synchronized to the test pulse pattern of generator 15, and the fault rate is indicated on indicator 5. In an alternative arrangement, Fig. 2 (not shown), looping takes place between two "go" lines and the comparator, generator 16, and indicator 5 are located at a different terminal station. The testing apparatus can be constructed as a portable locating device.

Abstract: 932,109. Supervising unattended repeaters. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. April 12, 1961, No. 13223/61. Addition to 914,788. Class 40 (4). In a carrier telecommunication system of the kind described in the parent Specification, some of the repeaters contain rectifiers in series with the resistors across the supervisory leads. A fault in the line between two repeaters e.g. AP1, AP2 causes relays B, C, D to drop out and thus causes contacts B2 to introduce a resistor RB2 of characteristic value and rectifier MR1 across supervisory leads B, D. A meter M1 is calibrated so that the approximate position of the fault can be read off directly but in order to localise it more exactly reversing switches RS1 and RS2 in the terminal station BN are operated manually and consequently the meter will now read zero since the rectifier is non-conducting in the reverse direction. If the fault had occurred between repeaters AP2, AP3 then reversal of the supervisory current would produce no change on the meter.
