Title: Traffic recording in telephone exchanges
IPC: H04M3/36
Filed: 1976-01-15
Abstract: 1484206 Automatic exchanges STANDARD TELEPHONES & CABLES Ltd 15 Jan 1976 [23 Jan 1975] 2999/75 Heading H4K In an automatic telephone exchange in which data relating to calls to be set up are conveyed on common signal paths which extend between control units of the exchange, the common signal paths also extend to a traffic recorder. In the embodiment the exchange includes a switching network 1 to which peripherals, such as subscribers, e.g. 4, 5 junctions, e.g. 6, 7, registers REG and links, e.g. 2, 3 are connected. Cyclic stores and scanners CS operate in synchronism with equipment which scans the peripherals through gates LG, RG so that information about a peripheral being scanned from CS and about the state of the peripheral from gates RG, LG is passed to further control equipment MCU. The same information, representing traffic conditions, is passed to traffic recording equipment. Traffic recorder: stores ST1, ST2 hold lists of peripherals in respect of which traffic statistics are required; different stores are used since different types of peripherals need to be scanned at different frequencies. A scan select unit SS selects the store to be readout and the codes of peripherals stored in the selected store are read out, one at a time to a comparator COMP and an output control circuit OCC; when the last code is read the cycle is repeated until SS changes. The codes reaching OCC are recorded by ORD. The comparator COMP compares the outputs of CS and SS and when they are the same informs gate TG which also receives information from a timing circuit T and the busy/free condition of the monitored peripheral. When a busy condition is detected TG increments counter BC. At the end of the scan cycle the contents of BC are passed to ORD via OCC for recording. The codes read from ST1 or ST2 may be identifications of subscriber line, outgoing junction, register or other peripherals.

Title: Improvements in or relating to recording instruments
Filed: 1933-02-03
Abstract: 401,919. Recording-apparatus. ELECTROFLO METERS CO., Ltd. and DUNGLINSON, B., Abbey Road, Park Royal, London. Feb. 3, 1933, No. 3334. [Class 106 (iv).] A recording-instrument comprises a pointer, a depressor for periodically moving the pointer towards a travelling record sheet, an inked ribbon interposed between the pointer and the sheet, a cam for actuating the depressor and a second co-axial cam for displacing the ribbon so that a mark on the sheet may be observed very shortly after it is recorded. The pointer 8 moves behind a scale 48 and is periodically pressed into contact with the ink ribbon 22 and record sheet 9 by a bar 12 actuated by a cam 19 through a lever 17 and link 16. The ribbon is carried by levers 24 pivoted at 25 and having arms 26 actuated by a cam 28 to move the ribbon to the left after the making of a mark. The instrument is adapted to record results transmitted from several distant measuring instruments, e.g. pyrometers, to each of which it is connected in turn by a selecting switch. The record corresponding to each distant instrument is made in a distinctive colour, the ink ribbon being given small displacements for this purpose by a cam 32 acting on an arm 30 connected to the levers 24. The distant instrument in circuit at any time may be visually indicated. If the depressor bar 12 is in its active position when the front casing 2 is opened, it is lifted by a cam on a bar 42 pressed to the right by a spring. The whole recording movement is slidably carried for easy removal on rods 4. Zero and sensitivity adjustments may be effected from outside the casing by turning stub shafts 35 having key-like ends engaging slots 37 in the ends of the adjusting members proper. A silk ribbon is interposed between the pointer and the inked ribbon to prevent sticking.

Abstract: 682,654. Centrifugal compressors. DAIMLERBENZ AKT.-GES. Feb. 12, 1951 [Feb. 10, 1950], No. 3401/51. Class 110(i) A super-charger for an internal-combustion engine comprises a diaphragm having fixed blades 9 which impart whirl to the air, the diaphragm being disposed within a tapered part 4 of the casing so as to be axially displaceable in the direction of flow against the action of spring means. To provide a rate which increases with the deflection, the spring means may be a helical spring of conical or waisted form. Alternatively, as shown, two helical springs 12, 16 of different rates and separated by a slidable ring 13, are used. Up to about 2/3 of the maximum speed of the compressor, the air passes mainly through an annular space 17. Beyond this speed, the diaphragm is drawn towards the impeller 2. The resultant diminution of the space 17 causes an increasing proportion of the air to pass through the blades 9, and the resultant increase in the whirl imported to the air limits the pressure developed.

Title: Improvements in or relating to loading control mechanisms for cyclical centrifugal installations
Inventor: GOODWIN RALPH CLEVELAND
IPC: B04B11/04
Filed: 1962-01-30
Abstract: 991,796. Centrifugal strainer separators. WESTERN STATES MACHINE CO. Jan. 30, 1962, No. 3448/62. Heading B1D. A loading gate 5 at the end of the spout 4 of a tank 3 (all seen in elevation) is first opened by admission of air to a cylinder 10 which rocks opening lever 9, 7 about fulcrum 8. Charge material is thereby admitted to a centrifugal strainer basket 1 (seen in horizontal cross-section), while at the same time the opening action of the gate, through link 18, control unit 20, links 17, 21, and shaft 16 moves a charge feeler 15 anticlockwise towards the cake 2 being formed in the basket. As the cake increases in thickness, the charge feeler 15 is forced to move in a clockwise direction and thereby, through the mechanism referred to, to effect progressive closing of the gate 5 until, through a limit switch 31 (associated with mechanism 20), and related circuitry, the gate is closed without further dependence on the position of feeler 15. Thus far, the apparatus is almost identical with that shown in Fig. 1 of Specification 717,899 (referred to). The present invention includes further apparatus modifying the extent of opening of the loading gate 5 in accordance with the flow rate (which is a function of the viscosity and hydrostatic head of the charge material), so as to maintain a predetermined flow rate during successive loading cycles. An adjustable stop element 29 is automatically actuated so that, if the flow rate is low because of high viscosity or small hydrostatic head, element 29 is adjusted for increasing the initial opening of gate 5, and vice versa. This is effected by using the pressure of the charge material at a point A in the spout 4 to regulate, by means of a pipe probe 63 and a valve 70, the amount of compressed air flowing from a supply conduit 74 through a conduit 76 to a pneumaticallyoperated positioning device 100 which adjusts the stop 29. In Fig. 5 (not shown), certain parts of the mechanism of Fig. 1 are slightly simplified.
