Title: Improvements in or relating to heat exchangers
IPC: F28F1/36
Filed: 1959-08-05
Abstract: 917,278. Nuclear fuel elements. CENTRAL ELECTRICITY GENERATING BOARD, WILLIAMS, F., and PRICE, C. F. July 28, 1960 [Aug. 5, 1959], No. 26778/59. Class 39 (4). A multi-finned polygonal heat exchanger for a gas-cooled nuclear reactor comprises a central tubular can 10 of a fuel element around which extend a number of integral radial fins 12 in helical paths, the can 10 being coaxial with an outer sleeve 11 of graphite or magnesium alloy in longitudinal slots 13 of which are fitted radially extending vanes 14. The vanes 14 are secured in the slots 13 and thus make a gas-tight fit in the outer sleeve 11, being secured, for example, by spot-welding through holes 15 provided for this purpose. Slots 16 cut in the fins 12 slidably receive the inner portions of the vanes which extend as far as the outer surface of the can 10. By thus preventing gas from passing from one zone to the other, a substantial reduction is obtained in the pressure drop across the heat exchanger compared with existing types of construction. Reference has been directed by the Comptroller to Specification 847,214.

Title: Radar apparatus
IPC: G01S13/78
Filed: 1968-06-06
Abstract: 1,218,624. Pulse radar. INTERNATIONAL STANDARD ELECTRIC CORP. 6 June, 1968 [9 June, 1967], No. 26936/68. Heading H4D. Radar apparatus for determining the commencements and the ends of transponder targets in a radar sector comprises a shift register to store a succession of responses received from such a target, and a threshold device which determines the commencement and the end of such a target dependent upon the number of responses received. Means is provided for checking the stored responses, which means is subdivided into a plurality of processing means for checking or testing, in the first of which only the responses stored in one part of the shift register is evaluated, with respect to a relatively high threshold value. In subsequent processing means the portions of the shift register to be evaluated are enlarged and the threshold values are changed, so that the ratio between the threshold value and the portion of the shift register to be evaluated is progressively reduced. As described, incoming response pulses from an interrogated transponder are taken directly to one input of an AND-gate U1 and also through a time delay element LZ to the other input of said gate. The delay introduced by the element LZ is equivalent to the time spacing of the framing pulses of a response message (e.g. 20À3 microseconds) and when there is coincidence between a delayed leading framing pulse and a directly connected lagging framing pulse, the gate U1 gives an output which is fed to a shift register SR, controlled by interrogating timing pulses from a control unit ST. In this way successive responses from the transponder, as the radar beam sweeps over it, are recorded in the shift register as it is stepped forwards by the interrogating pulses. The first three stages of the shift register SR are connected to first inputs of AND-gates U2, U3, U4 whose second inputs are connected to the control unit ST and whose outputs are applied through an adding circuit AD to one input of a comparator V. The other input of the comparator V is obtained from a threshold device SE 1 and it is switched by the control unit ST operating on an AND-gate U6. The device SE1 establishes a criterion, which may be 3 out of 3, so that the comparator V only provides an output, signifying the beginning of a target, if the contents of the first three stages of the shift register SR satisfy that criterion. Thereafter, the contents of further stages of the shift register are applied to the comparator under control of the unit ST, each subsequent threshold device SE2, SE3, &c., providing a lower criterion. Thus, the device SE3 may have a criterion of 6 out of 12. In a second embodiment (Fig. 2, not shown) a forwards-backwards type of shift register and counters which read, respectively, stored responses and re-setting pulses, are used.

Abstract: 1,106,462. Addressing stores; printers. INTERNATIONAL BUSINESS MACHINES CORPORATION. 17 June, 1966 [12 July, 1965], No. 27075/66. Headings G4C and G4H. Data storage apparatus comprising storage locations arranged in two groups and two sets, each set including some of the locations in both of the groups, comprises means for addressing the locations sequentially with successively addressed locations being in different groups, including a bi-stable device for selecting either of the groups and a bi-stable device for selecting either of the sets. Assignment of addresses to character positions in a core matrix store is as shown in Fig. 4. In particular, successive addresses 1, 2, 3, 4 . . . occur in alternate ones of the upper and lower halves of the store as shown. One of two groups of six rows is selected by a trigger U1, and triggers A, B, C, D select a row in the selected group as shown, via magnetic cores. Similarly one of two groups of ten columns is selected by a trigger T1 and triggers A, B, C, D, E (different from those used for the rows) select a column in the selected group as shown, via magnetic cores. Incrementing pulses can be arranged to cause the triggers to address the character positions in numerical order cyclically, incrementing by one or two positions at a time, i.e. 1, 2, 3, 4 . . . 240, 1, 2 . . . or 1, 3, 5, 7 . . . 239, 1, 3 . . . the triggers A, B, C for the vertical dimension acting as a ring. In addition, the circuitry can go from address 87 to address 239 in only a few steps. The store is used for storing a coded representation of each character on the type chain of an " on-the-fly " printer for comparison with the characters to be printed (read from a second core store) to control the print hammers. The addressing circuits of the stores are advanced in synchronism with the movement of the type chain. A check on synchronism between the addressing circuit of the first store and a " home " pulse from the printer chain drive is mentioned, and the characters in the second store each include a parity bit.

Title: Improvements in and relating to artificial arms
IPC: A61F2/68
Filed: 1920-09-24
Abstract: 172,166. Sandling, G. M. Sept. 24, 1920. Limbs, artificial.-Relates to a locking-device for artificial arms of the type in which a spring- pressed plunger is arranged upon one member and caused to move by means of a strap or other body harness into engagement with a toothed sector or equivalent mounted on the other member and particularly to that type in which the locking-plunger may be retained out of engagement with the sector to permit free swinging movement of the lower arm-member until it is automatically rendered operative again by movement of the pulling strap. In Fig. 2, the toothed sector e is shown engaged by the spring-pressed bolt f<1> which is operated by the strap w. Revolubly mounted on the upper portion of the bolt f<1> is a collar h with a projection j, Fig. 3, normally in engagement with a recess j<1> in a sleeve f through which passes the upper portion of the bolt. This collar may be retracted and rotated against the action of a spring i, retraction of the collar at the same time effecting disengagement of the bolt from the sector since relative longitudinal movement between the collar and bolt is prevented. The collar is kept in this position by means of the projection i thereon engaging a projection f<12> on the sleeve f. On the strap being pulled again, the projection j clears the projection f<12> and the spring i restores the collar h to its normal position thus allowing the spring g to restore the bolt f<1> to its operative position.

Abstract: 1341898 Automatic phase control KOKUSAI DENSHIN DENWA CO Ltd and FUJITSU Ltd 19 April 1971 [10 April 1970] 27308/71 Heading H3A A phase-locked loop comprising an oscillator 5 and a phase comparator 3 which compares the phase of an input signal (applied to transistor 611) with that of the oscillator signal to provide an error signal for adjusting the oscillator frequency, is characterized by the provision of a second phase comparator 7 which compares one of the two signals with a phase shifted version of the other to provide a further control signal which initially shifts the phase of the oscillator signal by a predetermined amount, if the phase of this signal is initially nearer to a pseudostable point of the loop, than to the true stable point. A signal modulated to one of two phases applied to the base of transistor 611 is frequency multiplied at 61 and applied to one input 31, 71 of phase comparators 3, 7. The output from oscillator 5 is fed via variable phase shifter 65, 63, 64, 67 to a second frequency multiplier 62, the output from which is fed to a switching circuit 6 which can connect it to either the phase comparator 3 or via a phase shifter 10 to comparator 7 depending on the polarity of a control signal applied between A and B. When a start of burst control signal is applied to bi-stable 12 it switches to provide control potentials at A, B which actuate switch 6 to connect the oscillator output to comparator 7. The output from this comparator is fed to a sense detector 8 which produces a positive output if the signal is nearer a pseudo-stable point than the true one. If it is positive a signal is applied via gate 68 to switch bi-stable 69. Gate 68 is opened by a pulse from monostable 11, triggered by the switching of bi-stable 12. Which bi-stable 69 switches it changes the polarity of phase reversing switch 67 to shift the phase of the oscillator signal towards the true stable point. Switch 6 then connects the oscillator output to comparator 3 to provide normal loop control. In modifications the input signal may be switched instead of the oscillator signal, Figs. 4, 6 (not shown). In the modification of Fig. 4 also, the oscillator signal is phase shifted by using the output from the sense detector 8 to modify the oscillator control signal via a combiner (13).
