Title: Improvements in and relating to a method of and means for changing and transferring fluid temperatures
IPC: F28F13/02
Filed: 1918-12-31
Abstract: 155,303. Shaw, E. Jan. 25, 1918, [Convention date]. Plate apparatus; concentric straight-tube apparatus; tubes of special section.-In an apparatus for the exchange of heat between two volumes of flowing fluids, the formation of films of low conductivity, which may tend to accumulate on the surfaces of the ducts, is prevented by leading one or both of the fluids through ducts shaped so as to give an abruptly changing direction to the flow therethrough. In one construction an inner duct or pipe of substantially rectangular crosssection is formed either from a circular tube or from two plates 1, 1, Fig. 1, brazed together, and is transversely corrugated, with the corrugations of the upper surface alternating with those of the lower surface as shown, the whole being mounted in a casing. In a modification, Fig. 6, an inner annular duct is formed between two transversely ribbed cylindrical tubes 13, 14, and these tubes are located between outer and inner casings 7, 11, so that a flow of fluid is arranged through the duct from an inlet 16 to an outlet 17, while the other fluid flows on both sides of the duct in the reverse, direction from an inlet to an outlet 20. In other arrangements, the two ducts are formed by two concentric spirally-corrugated tubes which give a spiral movement to the fluids in addition to the broken longitudinal movement, or, where the spiral movement is not desired, a longitudinal partition extends along the annulus. Apparatus as in Fig. 1 may be used in catalytic reactions, the space outside the duct 2 being packed with catalyst and the temperature regulated by passage of a fluid through the duct.

Title: Detection of blemishes in surfaces
IPC: G01N21/89
Filed: 1972-07-29
Abstract: 1433126 Counting imperfections in surfaces FERRANTI Ltd 26 July 1973 [29 July 1972] 35611/72 Heading G4D The invention relates to counting blemishes in the surface of objects, which objects have odd shapes but whose surface, or the projection of the surface on to a plane, has an axis of symmetry. Apparatus for counting such blemishes has means arranged to scan the surface, or plane, line by line and derive an electric signal representing charges in reflectivity of the surface; means, responsive to the electric signal, producing an edge pulse each time the scan crosses the edge of the surface on to the surface; means generating a datum pulse at a predetermined point in each scan where the scan crosses the axis of symmetry; and means deriving gating pulses of substantially twice the period between an edge pulse and a succeeding datum pulse to gate the electric signal into a counter which thus counts only blemishes lying between the edges of the surface. The scanning apparatus (Fig. 1, not shown) employs a light source such as a laser, a rotating multifacetted mirror drum and a photodetector receiving light scattered from the surface. In Fig. 3 the photodetector output is applied to a threshold circuit 14 which passes only large pulses corresponding to the edges of the surface. Each leading edge pulse sets a bi-stable 15 which is reset by the next datum pulse at B. The output of bi-stable 15 is fed to an integrating amplifier 16 whose output is a rising voltage during period between edge pulse and datum pulse and a falling voltage for a following equal period. A second threshold circuit 17 detects when the output D is above a small value and opens the gate 25 to counter 26. A coincidence circuit 32 compares the trailing edge pulse with the gating pulse and operates an alarm or stops the count if the axis of symmetry does not coincide with the datum pulses. In an alternative arrangement (Fig. 5, not shown) the amplifier 16 is replaced by a counter which counts up during the period between edge pulse and datum pulse and then down at the same rate, the gate 25 being open while the count is above zero.

Title: Improvements in or relating to alarm arrangements suitable for use in telecommunication systems
Inventor: BOURA JOHN
IPC: H04J1/16
Filed: 1954-12-13
Abstract: 795,347. Protective arrangements. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd. Nov. 29, 1955 [Dec. 13, 1954], No. 36047/54. Class 38 (5). [Also in Group XL (c)] An alarm system for a thermionic valve arrangement comprises a plurality of gas discharge tubes V1, V2 any one of which strikes when the potential applied to it exceeds a predetermined value, the firing of the tube serving to operate an alarm and by its own light giving an indication of the identity of the faulty valve. When a tube V1 or V2 fires, it operates relay A or B whereupon contact A1 or B1 shortcircuits resistor R5 increasing the voltage on the grid of a gas discharge tube V4 causing it to fire. This in turn operates a relay C. Contact C1 provides a holding circuit for the relay, contact C2 earths the alarm line 13, and contacts C3 and C4 cause the potential applied to the right-hand electrode of the discharge tubes V1, V2 to rise so that the tubes will extinguish when the fault is cleared. The maintenance engineer now operates a locking switch KCA. Contact KCA3 breaks the alarm circuit, contacts KCA1 and KCA2 break the initial circuit for the gas discharge tubes V1 and V2 while contacts KCA4 and KCA5 extinguish the tube V4 and immediately re-ignite it. When the fault is cleared the corresponding relay A or B releases and contact Al or B1 opens releasing relay C4 and extinguishing valve V4. Contacts C2 causes the alarm to operate and this is stopped by restoring key KCA to its original position. Restoration of the key before the fault has been cleared and operation of the key under conditions of no fault are indicated by the operation of the alarm.

Title: Improvements relating to prepayment meters
IPC: G07F15/06
Filed: 1932-12-20
Abstract: 408,747. Prepayment mechanism for meters. CHAMBERLAIN & HOOKHAM, Ltd., and JAMES, S., 4, New Bartholomew Street, Birmingham. Dec. 20, 1932, No. 36072. [Class 27.] In a two-part tariff prepayment meter, mechanism is provided which, should there be arrears of basic changes to be paid, makes available, on insertion of a coin, or supply less in amount than would be obtained for that coin if there were no arrears. A restricted supply for each coin is obtained until the arrears are paid off. After insertion of a coin and rotation of a handle e, Fig. 1, a wheel f is rotated through 180 degrees so that one of two pegs g thereon engages the end h, of a lever b carrying a mercury switch a and rocks this lever to circuitclosing position where it is held by a shoulder p on a lever n. Prepayment also actuates epicyllic or other quantity mechanism to rotate an arbor i in an anticlockwise direction, this arbor being returned to its initial position to release the lever w and open the circuit by the consumption meter and by a constantly operating electric motor or clock, the motion of the latter being correlated to the fixed charges. The arbor i may be returned by a single motor driven at a constant minimum speed when no current is being consumed and at a higher speed when current is being taken by the consumer. The arbor has fixed to it a cam j and frictionally mounted on it an arm k with a peg l located in a curved slot m in the cam so that relative movement between the cam and the arm is restricted in one direction. A peg s on the arm k presses aside the lever n to open the switch a and holds it in unlocking position against the action of a spring g by engaging a recessed shoulder r. The arm k is thus prevented from further movement in the clockwise direction, but the cam j, if coins are not inserted, continues its movement independently of the arm, the extent of this movement corresponding to the arrears of fixed changes, which must be paid before a normal supply can again be obtained. The cam in this independent movement, by engaging a pin v on one end of a bell-crank lever t, rocks the lever t so that its notched other end u is moved over the peg s. On the insertion now of a coin, the arm k and cam j are moved together anticlockwise by the arbor i until the peg s engages the overhanging end u of the lever t. This stops the arm k, the distance it has moved corresponding to the restricted supply the consumer can obtain for a coin while arrears exist. The remaining movement given to the arbor i serves to lesson the angular distance between the cam j and the peg l. When sufficient coins have been inserted to cause the end of the slot m again to engage the peg l, the arrears will have been paid off, the restricted supply lever t returned to its original position, and the arm 7c will be permitted a full movement for each coin inserted. A notch may be provided in the end u of the lever t to engage the peg s when the arrears exceed a certain amount. This will prevent any supply of current from being obtained until the excess arrears are paid.

Filed: 1967-08-11
Abstract: 1,178,429. Associative stores. SINGER GENERAL PRECISION Inc. 11 Aug., 1967 [1 Sept., 1966], No. 37052/67. Heading G4C. A storage system has a plurality of registers holding characters to be matched against the stored data. The tracks of a magnetic disc store each hold one or more variable-length multi-character records in serial-by-bit form, each record ending with an end-of-record character. The tracks are read out together, the characters being read out at a given time being compared with each of n key characters held in respective recirculating shift-registers, one of the key characters being an end-of-record character. A plated-magneticwire store has a word for each disc track, each word having a first field comprising one bit for each shift-register, a second equal-length field, and a flag bit. Before each character time, the bits of the first field of each word are set to 1, and are subsequently reset to 0 if the respective disc character does not satisfy the comparison criterion with respect to the respective shiftregister character. Each shift-register has two associated flip-flops which serve to specify the comparison criterion to be used with the key character in it, viz. " equal to," " greater than or equal to," " less than or equal to," or " comparison criterion to be taken as satisfied irrespective of the characters." The comparison is achieved by gating the disc bits in true and complement forms to the word lines of the magnetic wire store in synchronism with application of a sequence of true and complement forms of the shift-register bits to the bit lines of the magnetic wire store, the sequence depending on the comparison criterion used, coincidence between word and bit line signals being required to reset the bits of the first field. At the end of each character time, the bits of the first field of each word are ORed into the corresponding bit positions of the respective second fields (which were all at 0 right at the beginning). Thus the second fields indicate which of the key characters (in the shiftregisters) have had their comparison criteria satisfied in the various records so far. The second fields are continually compared with those positions of an n-bit query register specified by an n-bit mask register. When the bit of one of the second fields associated with the end-of-record character is at 1 (indicating that a whole record has been compared against the shift-registers), equality in the comparison with the masked query register causes the associated flag bit to be set to 1 (this will cause a flag symbol to be placed at the end of the record on the disc to enable it to be subsequently read out). Whether equality is found or not at this time, the second field is reset to 0. Comparisons continue, of course, with any further records on the given track and the current and further records on the other disc tracks, in the same way.
