Title: Control system for a positive displacement rotary compressor
IPC: F04C28/24
Filed: 1965-01-20
Abstract: 1,087,751. Fluid-pressure servomotor systems. GARDNER DENVER CO. Jan. 20, 1965 [March 30, 1964 No. 2428/65. Heading G3P. [Also in Division F1] To reduce the power required to drive a positive displacement rotary compressor in its unloaded condition, a pilot valve 68, Fig. 1, responsive to pressure in the compressor discharge line 70 operates to control piston-actuated valves 66, 104, 106. The valve 66 controls the intake of air to the compressor and the valves 66, 104 the flow of oil which is used to cool, seal and lubricate the compressor. When the compressor is operating in its loaded condition, oil collected in the airreceiver 52 passes through a line 98 to a cooler 100 and thence by way of a line 102 to the valve 104. The valve 104 at this time connects the line 102 to a line 106 to supply a gear pump 96 drivingly connected to the main rotor shaft of the compressor which pressurizes the oil. The oil then passes through pump discharge port 96b to line 108, the valve 110 and a line 112 to an oil receiving gallery 38 in the compressor. When demands are satisfied, the pressure in the discharge line 70 rises to unseat the pilot valve 68 to operate the pistons of the valves 66, 104, 110. The valve 66 closing to cut off air supply to the compressor, the valve 110 interconnecting the line 108 with a line 134 connected to the receiver 52 and the valve 104 interconnecting the line 104 with a line 113 fitted with a now closed non-return valve 54 through which the receiver 52 is normally supplied. The pump 96 which is in operative circuit with the compressor outlet 34 now functions as an evacuating pump to extract any oil or air from the compressor which extract passes through the valve 104, pump 96 and valve 110 to the receiver 52. A choke 160 fitted between lines 102, 112 ensures that a sufficient quantity of oil from the receiver passes to the gallery 38 to lubricate the compressor when unloaded. The compressor described is of the inter-meshing screw type but the invention may be applied to other types of positive displacement rotary compressors, e.g., rotary sliding vane compressors or dry compressors in which latter case the gear pump could be replaced by a readily available source of vacuum.

Title: Method and device for enclosing a cable splice
IPC: H02G15/08
Filed: 1977-01-21
Abstract: The covering comprises a compressibly foamed plastic (24, 26), wound around the cables (12, 14) at a distance from the splice (10), and flexible film material (22) as a covering of the splice, which material is held securely on the compressibly foamed plastic (24, 26). The consequently enclosed cavity is filled by rigid-foamed plastic (46). This covering can be produced at low costs for labour and material, because the splice does not have to be fixed during curing; this is since the compressibly foamed plastic (24, 26) and the film material (22) form a housing in which the curing plastic (46) is pressed into all the cavities. Therefore, lashing errors are greatly reduced and any installation errors can be seen immediately and can be rectified. <IMAGE>

Title: Improvements in or relating to rotary compressor plants
Filed: 1958-01-27
Abstract: 846,339. Rotary compressors; gas turbine plant. ESCHER WYSS A.G. Jan. 27, 1958 [Feb. 1, 1957], No. 2662/58. Classes 110 (1) and 110 (3). Surging of a rotary compressor plant at partial load is prevented by shunting an auxiliary compressor across the discharge conduit of the main compressor, the auxiliary compressor being driven by a turbine and at least part of the medium to be compressed being expanded in the turbine from a pressure lying between the inlet and outlet pressures of the main compressor. In the plant shown, a threestage main compressor 25, 26, 27 is driven at constant speed by an electric motor 28. At part load, a valve 58 is opened so that air is diverted from the outlet of the first compressor stage 25 to drive a turbine 56. In addition, a throttle valve 48 is partly closed to divert air through a turbine 57 connected in parallel with it. The turbines 56, 57 drive an auxiliary compressor 37 connected in parallel with a non- return valve 42 in the discharge conduit of the main compressor. The non-return valve 42 is closed by the pressure developed across it by the compressor 37, and the latter provides an additional stage of compression downstream of the stage 27. If the throttle valve 48 is fully closed, the entire output of the stage 25 is used to drive the turbines 56, 57, and the stage 26 then draws in air direct from atmosphere through a non-return valve 51. Intercoolers 35, 36, 43 are provided. Turbine 57 may be omitted and the throttle valve 58 may be located at the outlet of the remaining turbine. A further throttle valve may be provided in the intake conduit 29. In a further embodiment, the auxiliary compressor is driven by a single turbine, of double-flow type, the turbine being connected in parallel with a valve located in the intake conduit of the first stage of the main compressor. The turbine is energized by closing the valve. Step-up gearing may be provided between the turbine and the auxiliary compressor.

Abstract: 549,785. Automatic exchange systems. WESTERN ELECTRIC CO., Inc. March 3, 1942, No. 2797. Convention date, Feb. 8, 1941. [Class 40 (iv)] , In an arrangement whereby a register-marker, e.g. of the kind described in Specification 530,085, can test the condition of the trunks of a group over a single circuit, each trunk has an associated discharge tube 106, 107 &c. which is ionized if its trunk is idle by a potential applied to its starting electrodes. The cathodes of all the tubes are connected together and over contacts of an associating relay such as 203 to the starting anodes of a similar group of tubes in the marker. Positive impulses are delivered to -the main anodes of the trunk tubes and negative impulses to the starting cathode of the marker tubes in succession and in synchronism so that when the groups are connected by the associating relay a discharge passes in the tubes of each group corresponding to idle trunks and the corresponding anode relays such as 217 are energized. When a trunk is taken into use, ground on its c-wire, to which a control electrode of the corresponding tube is connected, prevents the ionization of the latter.

Abstract: 1,166,841. Inverting circuits. PLESSEY CO. Ltd. 11 Jan., 1967 [21 Jan., 1966], No. 2814/66. Heading H2F. [Also in Division G3] A static inverter, of the type in which the third harmonic is eliminated from the output by combining two square waveforms which have the same frequency but are 60 degrees out of phase, is regulated by pulse width modulating each waveform or the combined output by a modulation signal of predetermined frequency and varying the degree of modulation to maintain a predetermined output, third harmonic cancellation being preserved by maintaining a fixed phase relationship between the modulating signal and the combined output. The Figure shows a three-phase arrangement in which the six square waveform outputs of a ring counter 16 are pulse width modulated at 18 by a trigger pulse generator 17 whose square-wave gating signal has its mark/ space ratio varied by a control 21 in accordance with variations of the output voltage of the inverter which is thereby maintained constant. The control 21 advances or delays the leading edge of the square waveform of generator 17 to vary its mark/space ratio. The fixed phase relationship is maintained by using a master oscillator 15 to supply the ring counter 16 and the pulse generator 17. After pulse width modulation the six ring counter outputs are amplified at 19 and then corresponding pairs are combined at 14 to produce a three-phase third harmonic free output which is filtered at 20 to produce a sinusoidal waveform. Transistors may be used as switching elements in the gating circuit 18 whose output may be switched off under overload conditions by protection circuits 22. Typical waveforms before and after pulse width modulation are illustrated and discussed, Fig. 1, 2 and 3 (not shown).
