Abstract: 990,358. Reactors. SOC. ALCATEL. Dec. 17, 1963 [Dec. 17, 1962], No. 49826/63. Heading G6C. The monitor of a nuclear reactor coolant gas is cooled to prevent damage of the scintillation counter and photo-multiplier by the high temperature coolant. The metal structure of the monitor is provided with a large heat dissipating surface secured to it by copper rods inserted into the structure. As shown, the monitor, of the type disclosed in Specification 923, 083, includes the conduit 18 through which the coolant to be investigated is passed, the rotary drum 15, the associated scintillator 22 and multiplier tube 20. The flow of heat from the gas in 18 to units 20 and 22 is reduced by the heat-insulating barrier 14 and the copper rods 4. The latter conduct heat to the heat dissipating cylinder 29 cooled by fan 30. A Peltier cooling unit is also inserted at 32.

Abstract: 1,059,729. Feeding webs. ROYAL PACKAGING EQUIPMENT Ine. Dec. 17, 1963 [Dec. 17, 1962], No. 49846/63. Heading B6B. [Also in Divisions B5, B8 and F4] In a method of forming packages from a pair of superposed webs of heat sealable material the lower web 200 is fed from roll 107 by an endless chain conveyer 202. Mounted on the chains 202 are clamps 217 each comprising an upper spring member 220 mounting roller 223 which rides over an opening member 229 at each side of the web having a cam 230 which forces the end 235 of a spring 220 away from the clamp base 218. Initially the web margins lie over the springs 220 but as each is moved against the tucking edge 237 of a plate 231 it is forced under the spring end 235. The clamp 217 then closes on the web as the rollers 223 move off the cams and the edges of the web are thus securely gripped. Rollers 225, 226 run in guides alongside the chain, the guides for the former ensuring transverse tautness in the web.

Examples are given for the production of the compounds. Intermediate 5 - chloro - 2 - nitro - 4 - trifluoromethylanilines are isolated in some examples. The products are useful as herbicides and may be used for the control of grassy weeds in the presence of crops.

Abstract: 1,041,660. Fish treating machines. INSTITUT FUR SCHIFFBAU. Dec. 9, 1964, No. 50072/64. Heading A2U. A device for feeding fish to a fish treating machine comprises arcuate conveyer trough 3, fish support 5 provided with stationary guide rail 25, sensing lever 7, centring guide members 26 and cam 16 and displaceably mounted head support 6. The lever 7 senses the thickness of the fish and the position of the head support 6 and the height of the fish support 5 is adjusted accordingly. When trough 3 receives a fish from trough 30 on a conveyer, it is pivoted into fish support 5. The fish contacts sensing lever 7 which causes locking link 10 to be disengaged from cam 11 and thus allowing shaft 14 to be rotated, head support 6 to be retracted by spring and fish support 5 to be lowered as part 28 moves over cam 16. Retraction of part 28 causes shaft 14 to be rotated till lever 29 causes link 10 to engage cam 11, which prevents further retraction of head support 6. The fish engaged by head support 6 is gripped by gripper means (not shown). Cam 17 is now in a position to hinge the head support 6 downwards to allow the fish to be conveyed further. Then cam 17 erects head support 6 and cam 18 effects adjustment of the head support to its original position, i.e. in a position to receive the smallest size of fish.

Abstract: 1440926 Cutting apparatus A SCHMERMUND 16 Oct 1973 [31 Oct 1972] 50095/72 Heading B4B A device for cutting continuous webs into lengths comprises two web feed paths each having a portion common to the other, respective cutting means 2, 3 and 102, 103 associated with each feed path, respective web feed means 1 and 101 selectively operable to feed a web past the respective cutter means in co-ordintaion with the displacement of a displaceable knife element 3 thereof and web change-over means selectably actuatable to render inoperative substantially the feed means and cutter means associated with one feed path and to render operative substantially simultaneously the feed means and cutter means associated with the respective other feed path. Considering one feed path only, the cutter element 3 is mounted in a rotatable drum having gear teeth in mesh with a gear wheel 15 mounted on a sleeve 18, 19 sliadable on a drive shaft 25. After the web is severed, the cut portion is carried away via a suction-type conveyer band 5, feed rollers 8 suction roller 9, 11 and feed rollers 12. The drive from the shaft 25 is transmitted to the gear wheel 15 by means of member 20, 120 secured to the shaft and having clutch dogs for engagement with dogs in the sleeve 18, 19. As shown in Fig. 1, the gear 15 is drivingly connected to the shaft for rotating the cutting element 3 while a gear 115 meshing with teeth 116 on the cutting element 103 is disconnected from the driving sleeve 120. When the left-hand web is nearly used up the gears are moved on the shaft 25 by means of a rod 24 such that the gear 11 is disengaged from the drive sleeve 20 and the gear 151 is engaged with the drive sleeve 120; movement of the rod 24 also actuates a switch 21 such that, simultaneously, the drive for the feed means for the left-hand web is disconnected while the feed means for the righthand web is started. In a modification, Fig. 2 (not shown), in order to allow a gap to form between the leading and trailing ends of the cut portions of the web, suction conveyers (9), (109) corresponding with suction conveyers 5,105 of Fig. 1 are arranged to run at a higher linear speed than that of the feed rollers 1, 101 thereby causing a gap to form after the web has been cut. In a further modification, the meshing gears 15, 16 and 115, 116 may be adapted to actuate reciprocable cutters instead of rotary as shown.

The top half of a bottle (see Fig. 1, not shown) is made by drawing a heated thermoplastic sheet 50 between upper and lower die assemblies 52 and 51. In operation, assembly 51 is raised until the sheet is clamped and shaped between a shaping ring 55 and the bottom of member 56 (see Fig. 3, not shown), the sheet being drawn a small distance into the cavity 57 by a ring 58. Member 62 is then raised relative to the rest of assembly 51 and the sheet is fully drawn into the cavity and shaped between the upper end of member 62 and the lower face of a second shaping ring 63. During this time air under pressure is supplied through member 62 and vacuum applied to cavity 57 to draw the sheet into close conformity with the cavity. The whole of assembly 57 is then raised further and the member 56 and the ring 55 are moved upwards relative to fixed cutting ring 81 so that the article is severed from the rest of the sheet. Simultaneously, member 62 and ring 63 are moved upwards relative to punch 68 against the action of springs 67, thus cutting out the central aperture from the article, the cut-out portion being removed by gravity through duct 82.

In a dynamo-electric machine as described in the parent Specification, the commutator is provided with an odd number of collector segments, the radial magnetic field traversing the cylindrical winding occupying the annular air gap between the fixed permanent magnet and the surrounding iron yoke is designed to have a value which varies sinusoidally in a circumferential direction and the commutator brushes are so positioned with respect to the stationary magnetic field that the integrated sum of the torques applied to the cylindrical winding (a) when no commutator segments are short-circuited one to another, and (b) when two commutator segments are so short-circuited, weighted to take account of the times for which they are respectively effective, are maximized. By using an odd number of commutator segments the frequency at which the variation in torque, due to periodic shortcircuiting of adjacent segments together, is increased over that obtained when a similar even number of segments is used, while the amplitude of the variation is reduced. By suitably positioning the commutator brushes with respect to the stationary magnetic field, the overall torque, derived by compounding the products of the magnetic induction and current distribution in the coils for both possible condition of the commutator, may be arranged to achieve a maximum value.
