Abstract: 1,158,917. Printing radiographs. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM) and UNIVERSITA DELGI STUDI DI PISA. 15 Aug., 1966 [17 Aug., 1965], No. 36400/66. Heading H4F. A device for plotting data stored on punched tape and representing a two-dimensional distribution of a measured value comprises a tape reader connected to a printer via a variable programming element by means of which different symbols of the printer can be assigned to selectable ranges of the measured value. In an embodiment for plotting radiodiagnostic data, measurement pulses from a scintillation counter are fed to a tape punch (and hence via the tape reader and programming element to the printer) and to a second printer for numerical representation. The second printer is preferably an electric typewriter arranged to type columns of two-digit numbers proportional to measured radio-activity, such that co-ordinates of the number on a typed sheet correapond to coordinate positions of a scintillation counter scanned over a body part, the columns being typed in red and black alternately. The tape reader output is fed to the programming element for division into e.g. five radiation intensity ranges and one of five print symbols (e.g. square areas of different sizes) is assigned to each range so that the first printer, scanned conformally with the counter, prints a scintigram in which "no symbol" represents zero activity and total blackness represents maximum activity. Adjustment of the programming element enables the scintigram contrast to be varied.

Title: Value/use control and identification system for magnetic cards
IPC: G06K7/08
Filed: 1974-08-21
Abstract: 1457051 Card reader RUSCO INDUSTRIES Inc 21 Aug 1974 [4 Sept 1973] 36734/74 Heading G4M A reader for a spot magnetized card such as a ticket or parking card having an identification section and a value/use section has a portion determining the identity of the card and a portion altering the recorded value in the value/use section only if the identity is established. The card 10 is inserted through a slot in the reader and operates switch 32 which via flip-flop 34 enables clock generator 36 which successively produces a clock pulse on each of leads C1 to C8. Pulse C1 enables the read out sensors which are aligned with the magnetized spots on the card. The identity code may consist of randomly distributed spots. Latches 18 are set by the code and latches 20 by the value/use portion which contains a value in Gray code indicating the number of journeys remaining. The identity code is fed to a code board which can supply selected true or false outputs of each latch to a comparator which may be an AND gate producing an output only if a predetermined code is read. A false code causes disable gate 46 via flip-flop 26 to disable the clock generator. Similarly, if the Gray code reads zero gate 50 supplies a signal to the comparator causing disable gate 46 to disable the clock generator. If the predetermined code is read output driver 28 is enabled and clock pulse C3 feeds the binary conversion of the Gray code into a counter 56 where C4 decrements the counter value by '1'. C5 enters the Gray code conversion of the decremented value into latches 62 which feed selector gates 64. Gates 64 also receive the non-decremented Gray code and are arranged to supply at clock pulse C6 a signal to reverse the polarity of the spot that is different in the two codes. Electromagnets 16 then reverse the selected spot. C7 enables the output driver to e.g. release an access mechanism and C8 resets the clock generator. The remaining number of uses may be shown on a display 70.

Abstract: 848,697. Winding yarns, spindle apparatus. MUSCHAMP TEXTILE MACHINERY Ltd. (Foster Machine Co.). Dec. 1, 1956, No. 36818/56. Class 120(2). A winding head for an automatic yarn winding machine comprising a winding spindle and complementary yarn clamping members thereon, one of which is adapted to engage the core on which the yarn is being wound and is yieldably mounted on the spindle so as to be normally disengaged from the other or brought into engagement by axial pressure from the core, is characterized, in that the other yarn clamping member is also movable and by means for moving the same into an engaged or disengaged position for holding or releasing the yarn end respectively. In the arrangement shown 10 indicates a driving spindle having a slidable tip member 16 which engages and drives a bobbin on which yarn is to be wound slidably mounted on the forward end of spindle 10 is a sleeve 28 rotatively connected to the spindle 10 by pin 18. The sleeve 28 has a rearwardly facing clamping surface 30 which is in complementary relation with a forwardly facing surface 32 on a sleeve 34 which is slidable over sleeve 28. The relative axial movement between the two sleeves 28 and 34 is limited in one direction by engagement of the clamping surfaces 30 and 32 and in the other direction by the engagement of flange 36 with the snap ring 38, and a spring 37 is interposed between the two sleeves to urge them into this latter position. The sleeve 34 is made in two sections 39 and 40 to provide for adjustment between clamping surfaces 30 and 32. When the spindle is stationary or only rotating slowly rearward movement of sleeve 34 is prevented by top balls 48, disposed within suitable radial bores.50, engaging in an annular recess 54 in a collar 52 fixed to spindle 10. The arrangement such that when the member 16 is pushed back by engagement with a bobbin the sleeve 28 slides with it and the tail end of yarn is clamped between the surface 30 and 32. After a few turns of yarn have been wound the speed of the spindle 10 is such that the balls 48 are thrown out by centrifugal action so that the sleeve 34 slides rearwardly under the action of spring 37 thus releasing the tail end of yarn which is then wound into the yarn package being formed. When a finished bobbin is doffed the various parts are returned to the starting position by the two springs 24 and 37.
