Title: Data pooling circuits
IPC: G06F3/023
Filed: 1970-12-31
Abstract: 1317740 Data transmission system PERIPHERAL BUSINESS EQUIPMENT Inc 31 Dec 1970 [6 Jan 1970] 62039/70 Heading G4A [Also in Division H4] A data processing system has a plurality of input units each coupled to a separate pooling circuit coupled in a chain to carry data to and from a central tape or disc memory unit. The input units contain a keyboard 12 and a control panel 30. Data entered is displayed and previously recorded data is verified by comparing the recorded data with data re-entered on the keyboard by the operator. The pooling circuits respond to request and select signals and make internal priority selections. A parallel data bus from each input unit feeds a serial to parallel converter 50 in its pooling circuit 24. Priority selection circuits 60 operate a switch to by-pass the local converter and so pass data from a higher priority circuit or to connect the converter 50 to the transmission bus. Each pooling circuit includes a repeater 52 reconstituting the signal. The pooling circuits also have a switch and repeater transferring data in the opposite direction, each repeater transferring request RQ or select SEL signals which can be generated by a local control matrix 32. The pooling circuits contain (Fig. 3, not shown) frequency detectors, a clock circuit and two local oscillators, the RQ signal for instance being at 2À56 MH z  the SEL signal at À64 MH z  and data being at 160 kH z  and the signals may be self clocking. Each input unit contains a core store holding, e.g. 200 characters and having an address counter which overflows if more than 200 characters are provided and sets a flip-flop to generate the next phase of operation such as transfer of entered data or to terminate a record. The memory has field positions holding a specified number of characters and data entered can be justified in a field position with filler space codes used to fill unoccupied character spaces. Programme blocks on tape may be scanned until a particular block is identified and that block is then transferred along the pooling chain to a required unit.

Patent GB-707687-A (GB)
Abstract: 707,687. Counting-apparatus. KOMUSIN, E. Jan. 31, 1952 [Feb. 1, 1951 ; Feb. 1, 1951 ; Feb. 1, 1951], No. 2612/52. Class 106 (1). [Also in Group XVI] In a device comprising a recording and an adding mechanism, and means for setting the recording mechanism to a desired number and for controlling the adding mechanism in dependence on such number, the setting and controlling means include a disc having a cam surface operatively linked to spokes of a wheel for displacing at least some of the spokes, to render them operative for controlling the adding mechanism, when the disc is rotated, a plurality of spokes being connected and being jointly displaced on rotation of the disc through a predetermined unit, so that equal units of disc rotation render unequal numbers of the spokes operative.. In the apparatus shown, for stamping fees on postal packages, pence and shilling stamping wheels 29, 30, 31, Figs. 1 and 3, and discs 53, Fig. 8, are simultaneously set through toothed gearing by rotating numeral setting discs (not shown) connected to gear wheels 42, 43, 44, Fig. 1, which are mounted on a tiltable bracket 40. The discs 53 have cam slots such as 54, 55 so as to cause spokes such as 32 to project from the peripheries of wheels 12, 13, 14. Locking means are provided for preventing further displacement of the toothed gearing after an amount has been set and the gear wheel bracket 40 is moved to disengaging position by lever 41. When stamping is effected by rotating roller 15 through a complete revolution, the wheels 12-14 are rotated therewith so that the projecting spokes actuate gear wheels 20-22 respectively connected to numeral wheels 51, 52, 70, Figs. 1 and 4. The halfpenny wheel 51 is rotated one step for each step through which wheel 29 has been adjusted, one unit being transferred to penny wheel 52 for every other step. The cam slots in disc 53 for wheel 13, Fig. 8, however, cause four spokes in coupled pairs 32, 60 and 58, 62 to project during the first step of rotation of the disc corresponding to the stepping of disc 30 to value "4." The duo-decimal wheels 51, 52 are arranged on an auxiliary spindle 64 carried by a bracket 63 and lying adjacent the spindle 65 on which the higher (shillings and pounds) decimal or ten-position wheels 70, 75, 77 are mounted. The transfer mechanism may be of the " Maltese Cross " kind. The arrangement described enables largely the same mechanism to be employed for different (decimal and non-decimal) systems. Reference is made to applying the apparatus to the Indian money system and to weights and lengths.

Patent GB-2027544-A (GB)
Title: Testing brazed metal joints
IPC: G01N29/04
Filed: 1978-08-04
Abstract: A non-destructive method of testing for defects in brazed joints in metallic articles such as hollow copper electrical conductors comprising subjecting the joint (2) to a tensile force which is greater then the yield strenght of the metal of the metallic article (1) across the brazed joint (2) and thereafter passing a X-ray beam or an ultrasonic pulse through the brazed joint (2) to detect any gap which has been formed at the brazed joint (2) by the application of the tenside force. X-ray and ultrasonic testing of brazed joints does not reliably detect all defects in brazed joints, particularly butt joints, which might later result in failure of the joint under stress. The application of the afore-mentioned tensile force exposes such defects by creating a significant gap at the joint which is detectable by X-ray or ultrasonic test.
