Liquids and gases, separating. - A device for separating liquids and gases, particularly oil and gas, comprises a concentric tank 10, shell 18, sleeve 25 and baffle 21 surrounding a central gas outflow pipe 27. A jacket 13 may be fitted between the tank and the shell. The baffle is preferably surmounted by a catch basin 26. The mixture under treatment is supplied to the tank through inlets 11 provided with deflectors 12 to produce circumferential flow. The greater part of the liquid is withdrawn at the bottom of the tank while the gas carrying some liquid in suspension enters successively the jacket, shell, and sleeve through the apertures 16, 20, 25<1> and is deflected upwards by the baffle. Liquid is condensed on the shell, sleeve, baffle, and the upper and lower surfaces of the catch basin and escapes through pipes in the bottoms of the vessels. The apertures 20 in the shell are in the form of nipples to prevent the passage of liquid draining down the shell, but those in the sleeve are inwardly punched to facilitate the passage of liquid to the baffle. In a modification the sleeve is composed of vertical louvres inclined at an angle to the circumference.

Filed: 1972-07-18
Abstract: 1397274 Data processing system SIEMENS AG 18 July 1972 [30 Sept 1971] 33523/72 Heading G4A A data processing system includes a plurality of processing and storage units which are switchable into specific function states corresponding to respective modes of operation, a central station where the current function states, in respect of at least those states which may be assumed by all the units, are recorded, and a control circuit responsive to recorded function state changes indicative of faulty operation to interconnect the units in accordance with the detected function state changes. The system includes N duplicated processing units VEI1, VEII1; ... ; VEIN, VEIIN, duplicated program control units PEI, PEII, and duplicated stores SEI, SEII. Each unit may reside in one of three states viz. operational, testing, and fault. In general only units residing in the same state are allowed to communicate. Certain units may reside in other states, e.g. a store may be in a reconnect state where its contents are being updated, e.g. after disconnection and repair, and the program control units may reside in an "imitation test " state in which they may communicate with both operational and test state units. The state of the units is stored in a central register FZR, one being provided in each store. States which may only be assumed by certain units, e.g. imitation test, may be stored in the relevant units.  The system is arranged to respond to predetermined configuration of states to minimize the effects of faults. For example assuming a program control unit is operational and, due to a fault, both stores are in the test state so that neither can communicate with the program control unit, the program control unit is placed in the imitation test state and used to test the stores.

Title: Improvements in record card controlled statistical machines
Filed: 1953-12-02
Abstract: 737,849. Statistical apparatus. MAUL, M. Dec. 2, 1953 [Dec. 10, 1952], No. 33524/53. Class 106 (1). A special mark on a card controls a record card controlled machine jointly with a known group control device. A supervision device for card reference is provided for supervising the relative sequence of the cards with regard to each other and is under the supervision of a common supervision of an analysing device for a special mark of one of the cards impressing the group control device and the known group control device itself. Cards pass under analysing brushes Sb, bI, bII. The brush Sb serves for the detection of a summary card special punching, the brushes bI serve for the analysis of the valve perforations and the transmission of these valves to the elements of a known printing mechanism. The brushes bI, bII co-operate together in known manner for actuating a group control. When a summary card is detected by the brush Sb current flows from the negative line through contacts nIII and uI, the brush Sb, the contact nIV which is closed by its cam if there is a card passing under the brush Sb through the contact hI through relay H and A to positive. The relay H responds and actuates its contacts hI to hIV. By means of contact NI the relay M establishes a holding circuit through the cam contact nII so that it remains energized after the summary card hole has passed the brush Sb. Simultaneously with the analysis of the summary card by the brushes bI the brushes bII analyse the preceding card in order to compare the group number with that of the card under the brushes bI by means of group control relays G. If the group perforations are identical the relays G respond and actuate contacts gI to gIV and the machine continues to operate. If the group numbers do not agree one of the relays G will not respond and its associated contacts gIII will not be closed interrupting the supply to the motor M, and stopping the machine. Similarly if a group change is detected without a summary card being detected immediately beforehand the supply to the motor M will be cut off and the machine will stop. If two consecutive summary cards are sensed having a different group number without item cards between the relay M will respond, opening its contact hIII and shifting its contact hIV, and the supply to the motor m is again interrupted by one of the contacts gIII remaining open, stopping the machine and indicating the error. Specification 674,572 is referred to.

Title: Improvements in or relating to insulation testing arrangements for electric trolley buses
IPC: B60L3/04
Filed: 1945-12-12
Abstract: 620,395. Detecting, indicating, and locating faults; two-part couplings. GENERAL ELECTRIC CO., Ltd., and TURRALL, J. C. Dec. 12, 1945, No. 33647. [Classes 37 and 38 (i)] In apparatus for testing the insulation of electrical equipment installed in a trolley-bus, means are included whereby before the test can be carried out the section of line on to which the bus has been run for the purpose of the test is automatically isolated. The testing arrangement shown in Fig. 1 includes a test plug 34 which co-operates with a socket 22 on the bus for testing (1) the primary insulation IP, (2) the secondary insulation IS, (3) the total insulation, i.e. IP and IS with the single insulation SI, and is therefore generally similar to that described in Specification 531,762 except that the test plug 34 connected to the free end of the trailing cable 35 leading from the test panel 36 is inserted in a dummy socket 53 on the test panel 36 when the apparatus is not in use. Under these circumstances the dummy socket 53 energizes a coil 52 to close a switch 51, both provided on the test panel 36, and normal working prevails. Withdrawal of the test plug 34 for insertion in the socket 22 on a trolley-bus to be tested de-energizes the coil 52 to open switch 51 and isolate the negative line 3 so that the bus cannot be moved during the tests. As shown in Figs. 2 and 3, the plug 34 is cylindrical except for two flats 63 along its length. The aperture in the front panel 64 of the socket is of the same shape as the crosssection of the plug so that the latter can only be inserted when the apex of the V formed by the flats 63 points to the right-hand side of the socket. When the plug is rotated to the test position the contact segments 37-39 engage contacts 23-33 and the end of the plug 34 is flush against the panel 64 so that the plug is locked during tests. The aperture is normally covered by a flap 61. In a modification, Fig. 4 (not shown), which renders unnecessary the push-buttons shown in Fig. 1, the plug is formed with three sets of conducting segments interconnected in such a way that turning of the plug to three different positions connects the bus circuits in the correct manner for the three tests required.
