Title: Improvements in or relating to dosimetry
IPC: G01T1/115
Filed: 1964-02-14
Abstract: 1,041,303. Photo-electric dosage measurement. CONTROLS FOR RADIATION Inc. Feb. 14, 1964 [Feb. 18, 1963; Aug.29, 1963; Dec. 13, 1963], No.6345/64. Heading G1A. The radiation dosage that has been received by a thermoluminescent phosphor is measured by heating the phosphor and detecting and measuring the resultant light emitted. The phosphor may be lithium fluoride which has been exposed to an X- ray dosage of a few milli-roentgen. The phosphor crystals 88 are carried by a stainless steel tray 60 Fig. 5 (not shown) supported between two sets of contacts 26, 28 of beryllium copper, which grip the edges 62 of the tray 60. Oxygen-free gas, e.g. nitrogen, from a source 80 is passed over the phosphor specimen which is heated to 210‹ C. by passing a current through the resistive tray 60, the light emitted from the specimen being received by a photo-multiplier mounted above the specimen. The heating chamber has a recess in which slides a member 40 carrying the specimen tray. Felt blocks act as light seals against the sides of member 40, but do not restrict the flow of gas from the chamber, thus enabling all the oxygen to be flushed out. The measuring circuit Fig. 8, includes a timing motor 124 which controls the actuation Fig. 9 (not shown) of timer contacts in the circuit. When the specimen tray 60 has been slid in to position and the chamber filled with pure nitrogen, a button 94 is pushed to initiate heating, at which instant timer contacts 142 and 144 are opened and 114, 130, 132 and 136 are closed. The closing of contact 114 supplies power through switch 92 from a source 106 to the heating circuit. The closing of 130 completes a holding circuit for the motor 124, contact 132 connects the photo-multiplier 14 to the integrating circuit, while contact 136 removes any residual charge from capacitor 134. The light emitted by the specimen is sensed by the photo-multiplier, the signal from which is integrated by capacitor 134. The circuit is arranged to stop heating after a certain time and to disconnect the photo-multiplier (by the opening of switches 114 and 132 respectively). The charge stored by the capacitor 134 is then measured by an electrometer tube circuit, the output of which is applied to a digital voltmeter 112 and displayed on indicator 102. If the measured value is off the voltmeter scale, an extra capacitor may be brought into circuit by means of button 96 to reduce proportionally the charge on the capacitor 134 and to introduce a scaling factor of Î10 or x100, indication of these being provided by means of lamps 98, 100.

Title: Explosive welding
IPC: B23K20/08
Filed: 1969-02-06
Abstract: 1,262,563. Welding by pressure. AMF Inc. 6 Feb., 1969 [29 Feb., 1968], No. 6495/69. Heading B3R. In joining two workpieces they are heated and then explosively welded together. Two pipes 20, 22, Fig. 1, having complementary bevelled ends are held by clamps in drive means and are driven together until the bevelled ends abut and the pipes are then locked in position. An induction coil 24 supplied with current of 3000- 10,000 cycles per sec. is arranged about the pipes to heat the abutting ends, e.g. to 1400-2500‹ F. if ferrous, and a strip 28 of plastic explosive or primer cord is positioned between the coil and pipes. When the desired temperature is reached the explosive, e.g. ammonium nitrate, ammonium perchlorate, nitro-guanidine or dynamite, is detonated. Instead of induction heating, a single or a plurality of gas flames may be employed. To avoid danger of damage to the coil or gas ring the coil or ring and explosive are spaced and coupled together so that after heating the coil or ring is moved away from the pipe ends while the explosive is moved over the ends. In this case the initial heating temperature is higher to allow for cooling during movement of the explosive and coil. The joint formation may be an offset lap, a V-shaped double scarf or pure butt with the pipe ends possibly upset. To fill the dent created in a pure butt weld a strip of foil is arranged around the ends prior to heating and detonation and to fill the gap resulting when the ends are bevelled in opposite directions a triangular section filler piece is employed. An internal anvil may be positioned opposite the shaped ends and the ends of plates or the ends of a plate may be welded. The explosive may be positioned in a shaped chamber provided in an annular back up member to produce a directed blast effect or as shown in Fig. 13 the charge may be in two parts 108 in a back up ring 110 to produce forces urging the pipes 96, 98 together, the ring 110 and heating means 106 being coupled together and an anvil 102 being arranged within the pipes. The joint may be coated with borax or enclosed in a protective atmosphere. The explosive may be placed within the pipes or one charge may be provided on each side of the joint. In joining plates they may be arranged spaced and parallel to or at an angle to one another, borax being placed to fill the gap between the plates.

Abstract: 1,069,824. Positive clutches. MAAG GEAR WHEEL & MACHINE CO. Ltd. Feb. 15, 1966 [Feb. 17, 1965], No. 6551/66. Heading F2C. In a positive clutch the teeth on one of the clutch members, when in the disengaged position, are disposed between rows of circumferentially staggered teeth on the other member, whereby if one set of teeth are so positioned as to block movement of the member in one direction engagement may still be effected by moving the member in the opposite direction. In the form shown a toothed hub 2 on the driving shaft 1 is engaged by an axially movable sleeve 3 whose other end carries a row of teeth 6 which in the neutral position are disposed between two rows of teeth 7, 8 on a second hub 9 secured to the driven shaft 10. The teeth 6, 7, 8 are of the same pitch, but teeth 7, 8 are circumferentially staggered by a half pitch, and the opposed ends of the teeth are chamfered so that engagement can be effected by moving sleeve 3 to the right if leftward movement is blocked, or conversely. In an alternative form, Figs. 7-12 (not shown), the sleeve 3 carries two rows of staggered teeth mounted between three rows of aligned teeth on the hub 9, the tooth thickness being one quarter of the pitch and the teeth all having blunt square ends.

Abstract: 627,097. Feeding devices. WELLWORTHY PISTON RINGS, Ltd., and WOOLCOTT, A. J. March 11, 1947, No. 6732. [Class 117] [Also in Group XXX] Means for delivering split rings 12 in a predetermined angular position, and for substantially closing them comprise a shoot having a longitudinally extending tongue 16 in it to register with the ring gaps, a slide 20 reciprocable to move the lowermost ring from beneath the shoot to a position in line with and above a guide 29 having a predetermined taper along it, the slide having a projection 21 to register with the gap, and means for forcing the ring 12 from the slide through the tapered guide to close it to the desired extent. As shown, the shoot comprises opposed guiding faces 11, 13 the guide 13 being of a wide V-shape concave to the rings. The guides are adjustably mounted by bolt and slot connections 14 on a base 15 for different sized rings. The tongue 16 is carried by an arm 17 adjustably secured to the back of the .guide 13. The slide 20 is mounted in an axially adjustable manner by means of screws 22 which pass through slots 25 in the slide so that adjustment can be made to suit rings of different diameters, the thickness of the slide being not greater than the thickness of the rings. The rings are forced through the guide 29 by a pneumatically operated plunger 33 having a slot 34 on one side to receive the projection 21 of the slide. A longitudinally extending tongue 35 registers with the gaps in the rings 12, and in the zone of the ring gaps it tapers at 36 correspondingly to the diminution of the gaps in the rings in different positions along the guide. The tongue 35, in alignment with the tapered part 36 is chamfered at 39 to facilitate the introduction of the rings into the guide. The tapered part 36 terminates in a parallel sided part 40 of the thickness depending on a desired compression of the rings at the bottom of the guide. The main slide 20 may be adjusted relatively to the lower end of the hopper by means of a rotatable cam 44 acting on a supporting pillar 41. Specification 627,096, [Group XXII], is referred to.

Abstract: 1,101,781. Flash evaporators; desalination of water. BALDWIN-LIMA-HAMILTON CORPORATION. 18 Feb., 1965, No. 6963/65. Heading B1B In a multi-stage evaporator, for the desalination of sea water, comprising a series of flash chambers, operated at progressively decreasing temperatures and pressures, each chamber being in communication with a bundle of condenser tubes, part of the brine withdrawn from the flash chamber of lowest temperature is introduced into the tubes of an intermediate condenser, flows in series through the condensers of the stages of higher temperature and is then passed, via an auxiliary heater, into the flash chamber of highest temperature, the remainder of the brine withdrawn from the flash chamber of lowest temperature being discharged from the system. Make-up sea water is fed through pipe 40 into the stage of lowest temperature onto the uppermost of a set of de-aerating trays 42, which are offset as shown. Each tray has side flanges 47 and a downwardly-curved lip 48. The de-aerated water flows through perforations in tray 49 into the main water-stream flowing through the lower portion of the flash chamber. The water supplied to the de-aerating trays may be preheated by (1) passing it in heat-exchange with the heating-medium which has been used in the auxiliary heater, and (2) then using the water as cooling-medium for the condenser of a steamoperated air ejector. In a specific embodiment, there are 27 stages, and the water which is to be recirculated, from the last stage, is introduced into the condenser tubes of stage 23. Raw sea water is used as cooling-medium in stages 24 to 27, and is then discarded.

Abstract: 402,971. Broaching and like presses. OLDFIELD, T., 37D, Beverley Terrace, Boothtown Road, and SCHOFIELD, C., 9, Haddon Avenue, Skircoat Green, both in Halifax, Yorkshire. March 8, 1933, No. 6998. [Class 83 (iii).] In a rack-and-pinion operated press for broaching or other operations, a driving-shaft 4 continuously driven from a pulley 27 carries a gear 25 which drives the rack-operating pinion 5, loosely mounted on the driving shaft, through epicyclic gearing associated with a brake drum 13 which is held stationary to effect the working stroke of the ram 3. The extended hub of the pinion 5 is keyed to the hub 9 of an internally toothed disc 8 connected by planetary double gears 23, 24, mounted on studs secured to the brake drum, with the central driven gear 25. The drum 13 carries a brake-band 14 which is contracted by link mechanism 15, 16, operated through rod 19 by a treadle 20. The work-table 10 is counterbalanced by a weight 12 and the tool-head by a weight 30 through which passes a vertical rod 28 carrying adjustable stop nuts 28<A> and connected to the shaft 20A of the treadle. In operation, supposing the ram to be in its raised position, the treadle is depressed to brake the drum 13 whereupon the pinion 5 is driven in the opposite direction to the driving shaft through the gears 25, 23 and disc 8. As the ram descends the weight 30 is raised until it finally engages the stop nuts 28a thus raising the rod 28 and releasing the brake mechanism. The weight 30 is then effective to return the ram, the return being assisted if necessary by a friction washer 31 which is urged against the drum by a spring pressed collar 33 keyed on the driving shaft. The return of the ram is cushioned by a spring 37. When the ram is stopped in its highest position the disc 8 is also stopped while the double gear 23, 24 revolves idly around the gear 25 until the drum is again arrested by the brake mechanism for another working stroke.

Abstract: 1502370 Knitting-machines MEC-MOR SpA 19 Feb 1975 [28 Feb 1974] 7045/75 Heading D1C A circular knitting machine has a stationary cylinder (and dial, as shown) with a needlefree zone 7 and a thread cutting device 8, threads being fed from spools 9 on a fixed structure 10 to respective thread guide systems 11 at the zone 7 which are selectively movable to feed selected cut threads to guide means 62, 63 on a rotating structure 6 of the machine which in turn feed the threads to the needles. Each system 11 comprises a thread guide 11a and a guide lever 11b independently pivotable and controlled by cams 33, 40 rotating in synchronism with the machine structure 6. When a thread is cut at the end of a course, a tooth 41 on cam 40 frees a locking lever 43 to allow lever 11b to rise under spring force and the thread is trapped in a notch 21. Locking levers 36 are then freed by depressions 34 in the cams 33 but the guides 11a remain locked by levers 52 except for a selected guide for each feed which is released by a peg 57 on a programming chain 56 and falls under its own weight to feed thread into notches in the guide means 62, 63. The cut thread end is taken up by a suction port 67 and after a few needles have caught the thread its tension pulls down lever 11b to release the thread from notch 21. The thread guides 11a have progressively greater inclinations to prevent the threads of the respective guide means from fouling one another.
