Title: Data processing system timing
IPC: G06F3/09
Filed: 1965-10-26
Abstract: 1,134,005. Selective signalling. SCM CORP. 26 Oct., 1965 [26 Oct., 1964], No. 33176/68. Divided out of 1,134,003. Heading G4H. In a data processing system comprising two readers for reading respective sources of information and a utilization means for the information read by a first of said readers, simultaneous advance of the two readers being initiated by a common signal, the information read by the second of said readers is delayed before being transmitted to a portion of said utilization means which operates to stop the second reader upon detection of a particular signal. In the data processing system described more fully in the parent application and comprising two paper tape readers the paper tapes of which contain information in intermixed positions for the control of a typewriter and/or of a paper tape punch, only one reader normally being operative at a time and the operative reader being operated in a step-by-step manner by pulses from a source of constant frequency pulses, provision is made using common control and timing circuits for the two readers for skipping a first one of the readers up to the location of a particular control code whilst the second reader is still operating normally, the decoding of the signals from the readers on the common output channels taking place in time interlaced manner. For this purpose, clock pulses are generated such that each clock pulse occurs at the end of and is produced by the differentiation of the corresponding (transfer) pulse from said source of constant frequency pulses. Whereas the second reader is stepped and enabled by the transfer pulses and its signals decoded and utilized at or before the time of the corresponding clock pulses, the first reader is stepped by the transfer pulses enabled by the clock pulses and its signals decoded by pulses obtained by the differentiation of the trailingedge of the clock pulses. This so called special skipping may take place in either reader, continues during the time that advance of the operative reader is interrupted (of abridgment for parent application) and may occur whether or not the other reader is operating (e.g. may be called for manually).

Title: Improvements in or relating to automatic electric arc welding apparatus
IPC: B23K9/14
Filed: 1947-12-16
Abstract: 624,601. Uniting by fusion. WELDING SUPPLIES, Ltd. Dec. 16, 1947, No. 33201. Convention date, Dec. 19, 1946. [Class 83 (iv)] In an arc-welding apparatus of the kind having a carrier member mechanically moved in a predetermined course towards the work, and mounting an electrode holder so as to extend at an angle to the seam and keep the end of the coated electrode in contact with the work, means are provided for limiting the movement of the carrier member towards the work, and the electrode-holder is pivoted to the carrier member and means are provided for limiting the angular movement of the holder about .the pivot in the direction away from the work. Two such apparatuses may be used for automatic change-over from a used-up electrode to a fresh electrode. The holder 4 for the electrode 14 is pivoted at 5 on lever 3, which may be pivoted at 2 on a stand 1 resting on the work or may be replaced by a slide. The lever 3 has a stop 10 to engage the work when a predetermined length of rod remains and the swivel joint 6 has a pair of studs 11, 12, co-operating with the lever 3 to limit angular movement of the swivel joint. With the tip of the electrode resting against the work as in Fig. 1, the weight of the parts 3, 4, 14 maintains the socket 7 with the stud 11 engaging the lever 3. The arc is struck from the rod by inserting a conductor between the bared core and the work or by a torch, and when the rod 14 is nearly exhausted the stop 10 engages the work, thus preventing further motion of the lever 3. Melting of the rod causes the holder to turn about the pivot 5 under the weight of the parts so that the tip of the rod continues to travel along the seam to facilitate starting of a fresh welding rod 15 mounted in a similar apparatus to the rod 14. The rods may be connected to the same or different sources of current, and in the latter case the arc from the spent rod continues to burn for a while after the new arc is struck. The stud 12 checks the travel of the rod 14, thus preventing an excessive supply of weldmetal to the joint. The stop 10 may be adjustable or removable or the lever 3 or stand may be provided with an adjustable stop screw to co-operate with the stand or lever. The studs 11, 12 may be replaced by adjustable removable members to vary the angular movement, which is normally about 15 degrees. A weighted lever may be attached to the holder 4 or an extensionspring may act between the lever 3 and holder 4. For vertical welding, a spring may extend between the lever 3 and stand 1 and a weighted lever provided for securing the contact pressure between the rod tip and work.

Abstract: 669,695. Skips. DORMAN, LONG, & CO., Ltd., and CHALLONER, C. Oct. 18, 1950. [Dec. 29, 1949] No. 33274/49. Class 78 (iv). A ladle for carrying and dumping slag or the like mounted on a carriage adapted to run on rails, the ladle being disposed vertically on the carriage when 'carrying the slag, or when empty, and being adapted to be tipped on the carriage about a pivot in order to dump the slag is characterised by a smooth periphery roller and a co-axial toothed wheel rigidly mounted on each end or side of the ladle, a smooth surface track for each of said smooth rollers mounted rigidly on the carriage transversely or longitudinally thereof, the operative surface of said track being mainly horizontal with an arcuate depression therein, and a toothed rack for each of said toothed wheels mounted rigidly on the carriage transversely or longitudinally thereof, the said rack being mainly horizontal with an arcuate depression therein, the said depressions having a common axis in the vertical plane of the longitudinal or transverse centre line of the carriage, whereby the racks may be engaged by teeth of the toothed wheels and the said depressions may be engaged by arcuate portions of the said smooth periphery rollers and of the said toothed wheels when the ladle is vertical and so prevent involuntary tipping of the ladle, tipping being effected by applying a lifting force to one side of the ladle so as to cause the smooth and toothed wheels to roll out of said arcuate depressions on to and along horizontal portions of said tracks and racks. As shown, the skip is formed with a band 21 from which project stub axles 22 on each of which are secured by keys 25 a toothed wheel 23 and a roller 24, the wheel and roller each having a portion cut off at the top across a chord 26. The skip is mounted on the carriage 11 with the rollers 24 resting in arcuate depressions 19 in bearing members 18, and with smooth arcuate portions 27 of the wheels 23 registering with, but clear of, smooth depressions 16 in toothed racks 15 secured on the carriage. When the contents of the skip are to be dumped, the hook of a crane is engaged in a lug or eye 28 on the skip and the crane then operated to lift the skip whereupon the wheels 23 and roller 24 are lifted out of the depressions 16, 19. As the crane continues to lift, the rollers 24 roll on the bearing members 18 and the wheels 23 mesh with the portions 17 of the racks 15, the skip thereby tipping on an axis which moves gradually in a path 29 towards the tipping direction. Stops 30 on each side of the carriage limit the tipping movement. The wheels 23 and rollers 24 may be forced integral with the band 21 or with the skip.
