Title: Scanner for recording radioactivity distribution
IPC: G01T1/166
Filed: 1974-12-06
Abstract: 1484379 Body scanners PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 6 Dec 1974 [11 Dec 1973] 52867/74 Heading H4F Movement of the measuring head 2 of a body scanner in the Y-direction is accompanied by a movement of the body support table (not shown) of three times the distance in the opposite Y-direction The head 2 is directly coupled to a recording head 7 whereby a recording is made at one quarter scale of the relative movement between measuring head and body. To produce a corresponding reduction in recording scale for movement in the X-direction of head 2 (for which there is no accompanying movement of the table in the opposite X-direction) head 2 is linked to head 7 by a pulley and belt (or chain) system 11, 12, 19, 20, 22, 23 in which the pulley diameters are chosen to effect the 4 : 1 reduction in movement. In an alternative arrangement, Fig. 2 (not shown), the reduction is brought about by a double rack-and-pinion arrangement. For measuring over small areas of the body, the support table is held stationary. No reduction in the X-direction is then necessary; this is achieved by transferring the recording head drive from belt 23 to belt 22 so that the two heads move over the same distances. A mirror image recording may be made by transferring the head drive to the left-hand leg of belt 23. This is said to be used for a second measuring head arranged to scan underneath the body.

Filed: 1965-12-15
Abstract: 1,127,261. Wrenches. S. N. NORDGREN. 15 Dec., 1965, No. 53225/65. Heading B4W. In a wrench comprising a head 1 carrying a fixed jaw 2 and a handle 3 pivoted on the head at 4 and a movable jaw 5 having a rack 6 which co-operates with an adjusting worm 7 arranged in an opening 8 in the head 1, the worm is mounted on a bush 10 and is capable of limited movement along the bush, the bush being non- rotatably mounted on the worm shaft 9 and being capable of limited axial movement therealong, there being provided spring means 14 positioned between one end of the bush and the worm 7. The bush carries a washer 11 which is secured thereto, or slidable therealong. The end of the handle 3 is forked at 17 to form a groove in which engages a tongue projecting from the head, the two arms 17 engaging the washer 11 and effecting axial displacement of the worm assembly. Movement of the handle 3 towards a working position causes the bush 10 and the worm 7 to move along the shaft 9 until the bush engages a stop means on the jaw 2, and if the washer is slidable along the bush continued movement of the handle causes the worm to move relatively to the bush to compress the spring means 14. The handle 3 is biased into working position by a torsion spring 18 and the handle 3 may be locked to the head by a device 21.

Title: Sampling arrangement for use in electromechanical recording  apparatus
IPC: G01R13/00
Filed: 1970-11-09
Abstract: 1334530 Sampling circuit for graphical recorders MAGYAR TUDOMANYOS AKADEMIA KUTATASI ESZKOZOKET KIVITELEZO VALLALATA 9 Nov 1970 [13 Nov 1969] 53265/70 Headings G1J and G1U In order to display a cyclically recurring waveform such as A, Fig. 2, on a graphical recorder having insufficient bandwidth, the waveform is sampled repeatedly once during each cycle, at a sequence of points encircled in Fig. 2 - progressively advancing within each cycle, so that by displaying the successive samples graphically the form of the waveform will eventually be apparent. As described the input waveform A, Fig. 2 is applied to a square 1, Fig. 1, and pulse generator 2, to produce sync pulses B at the positive-going zero cross-overs. These are applied, via a normally open gate 3 to set a trigger 4. The output voltage D from trigger 4 is integrated R 1 C 1 , producing an exponentially rising voltage E which is compared 7 with a second, more slowly rising, exponential voltage F from a second integrator R 2 C 2 . When the two voltages E and F are equal a pulse generator 8 produces a pulse G which (i) opens a gate 5 thereby allowing a sample of the waveform A to pass to a recorder 6, (ii) resets trigger 4, and (iii) causes a circuit 9 to discharge capacitor C1, gate 3 being closed while this is being done. This process repeats until the sampling pulse G has processed through a complete cycle of the waveform A, whereupon, at the end of a cycle capacitor C 2  is dishcarge by a circuit 10 and the whole sequence is repeated. Three circuits are outlined for controlling the discharge circuit 10 to ensure that its operation is properly synchronized with the end of a cycle of the waveform A. In the first, Fig. 3 (not shown), circuit 10 is activated when a sampling pulse G coincides with a sync pulse B, in the second, Fig. 4 (not shown) for greater accuracy, circuit 10 is activated when the integral of the output voltage D of the trigger 4 rises to a reference level, and in the third, Fig. 5 (not shown) the second circuit is modified by differentiating the integrated output voltage D from the trigger 4, storing the result on a capacitor (C4) and using it to set a constant charging current (16) for a second capacitor (C5), and comparing (17) the voltage across the second capacitor with a reference voltage.

Patent GB-556146-A (GB)
Abstract: 556,146. Calculating-apparatus. LEWIS, J. H. Feb. 19, 1942, No. 2237. [Class 106 (i) ] A computing apparatus for determining the time of flight of aircraft comprises a number of different scales graduated in units of time and means for selecting any one of the scales, an index or pointer co-operating with the selected scale, a map and a member movable across its surface and attachable to selected points thereof, and means operatively connected to said - -member to cause relative movement between the selected scale and index proportional to the distance moved across the map surface. The computing apparatus, Fig. 1, is contained in a casing 10 and is associated with a map 12. Within the casing is a drum 14, Fig. 5, manually operated by worm gearing 24, 26 and carrying on its periphery scales 18 each pertaining to one particular ground speed and graduated in units of time. The selected scale 18 is viewable through an aperture 20 in the casing and cooperates with an index or pointer 22 carried by a plate . 34 supported on a shaft 38. On the plate 34 is mounted a pulley 46 around which passes a cord that is attached at one end to a rotatable drum 56, and that passes out of the casing through a fairlead 64 at the point of origin on the map to a ring 66. By this means the pointer 22 is moved along the scale a distance proportional to the distance between the points 64, 68 on the map. The drum 56 is utilized to adjust the initial position of the pointer 22. The particular scale 18 selected is determined by a selecting device arranged in the upper part of the casing and set in accordance with the air speed, the speed and direction of the wind, and the bearing of the point 68 from the point 64. The selecting device comprises a spindle 70, Figs. 3, 4 and 5, with an operating knob 80 and a disc 74 with an index mark 76 and equally spaced holes 88. The disc co-operates with an annular circle 78 graduated in degrees. The spindle 70 carries a bevel gear 90 to drive a drum 96, Fig. 5, with scales 100 viewable through apertures 102 in the casing 10. A pointer 82 loose on the spindle 70 has a pin 86 which normally lies in one of the holes 88. In operation the knob 80 is first turned to bring the index mark 76 in register with the zero graduation on the scale 78. The pin 86 is then disengaged and the pointer 82 is rotated until it is in register with the graduation denoting the wind direction. The pointer 82 is then locked to the disc 74 and the knob 80 rotated to bring the pointer 82 into register with the graduation representing the course bearing thereby bringing a set of scales to the apertures 102 which bear a definite relationship to the speed and direction of the wind and the course bearing. The scales are marked in accordance with air speeds and wind velocity.
