Abstract: 1511968 Chicken batteries SCHMIDT - ANKUM AGRAR - UND ZWECKBAU INH DR ALBERT SCHMIDT 8 Dec 1976 [9 Dec 1975] 51115/76 Heading AIM A broiler battery comprises a frame housing tiers 1-3 of cages, each tier providing a single cage having a floor formed by a perforated belt 6 having its ends joined by a cable 7 to form a closed loop, a rear end wall 8 of the cage being carried by the belt so that, when a front end wall is removed from a region 5a of the frame, the loop can be driven to bring the floor and rear wall 8 forwardly to facilitate removal of the chickens, which may be transferred to a transverse conveyor (Fig. 4, not shown) adjacent the front end 20 of the loop. A cleaning and disinfecting device 54 is provided under the lower run of the loop for cleaning the floor prior to retracting it to its normal position. The perforations allow droppings to fall through the floor to a channel 11 cleaned by a scraper 16. Feed troughs 14 incorporate conveyor chains supplied by a common food shaft 15. Water is supplied by a supply pipe 12 with drinking nipples, the supply pipe passing through rubber comb-like portions of the front and rear walls.

Abstract: 1,085,179. Lasers. HUGHES AIRCRAFT CO. Dec. 2, 1965 [Dec. 31, 1964], No. 51189/65. Heading H1C. In a solid state laser the laser rod is mounted on a thermally conducting pedestal which extends out of the pumping cavity enclosing the rod. A cylindrical ruby laser rod is situated along one focal line of an elliptical pumping cavity including a single straight light source substantially parallel to the rod. In order to regulate the temperature of the ruby it is supported along its length by and in thermal conductive contact within a pedestal which extends outside the pumping cavity through an opening of the cavity on. the opposite side of the rod from the lamp, Figs. 1, 2 (not shown). This pedestalserves as a conducting path. to a thermal radiator area or thermal regulators, Figs. 3, 4 (not shown). Conventional air fins may be attached to the lower portion of the pedestal or the pedestal may be attached to water jackets- and the apparatus may operate in itscooling or heating mode. The optical resonant cavity may comprise silvered end faces or dielectric flats or detached reflectors.

Title: Method of manufacturing tobacco smoke filters
Inventor: HEMMING DAVID HENRY
IPC: A24D3/02
Filed: 1963-12-30
Abstract: 1,100,116. Tobacco smoke filters. CIGARETTE COMPONENTS Ltd. 29 Dec., 1964 [30 Dec., 1963; 7 Feb., 1964], Nos. 51211/63 and 52127/64. Heading A2C. Multiple length filter rods are injected at axially spaced intervals with an additional material to form, when cut, first and second sections unitary with each other, the first section carrying throughout its cross-sectional area the additional material. Multiple lengths, e.g. sextuple length, filter rods, of e.g. cellulose acetate, are fed from a hopper 1 to channels 12 of a drum 3. The drum 3 is intermittently driven from a motor 11 via a wheel 9 having a roller 8 which engages a Geneva disc 7 having a gear 6 which meshes with a gear 5 on the drum 3. The motor 11 also drives a shaft 21 which has two cam track discs 23 and 24. Disc 23 serves to reciprocate a frame 17, slidably mounted on guide rails 18 and supporting pistoncylinder units 13, 14, 15 and 16, and disc 24 serves to reciprocate a cross-head 20, also mounted on the guide rails 18 and connected by rods 19 to the pistons of the units 13-16. A flexible conduit 27 feeds each piston-cylinder unit 13-16 with additional material from a reservoir 28. The additional material may be a liquid suspension of activated carbon or menthol. A guide 34 retains the filter rod lengths in the channels 12 prior to discharge on to a conveyer 36. Apertures 35 are provided in the guide 34 for passage of the needles 30, 31, 32 and 33 of the units 13-16. During the time when the drum 3 is stationary the cam discs 23 and 24 cause the piston cylinder units 13-16 to advance towards the filter rod opposite the apertures 35 and the needles 30-33 pierce the rod. At the same time the pistons 19 are moved forwardly so that there is no relative movement between the pistons and the cylinders. Relative movement to inject the additional material occurs during withdrawal of the piston and cylinders from the filter rod, the shape of the cams 23 and 24 being such that more material is injected as the needles are withdrawn through the centre of the cross-section of the rod. Various arrangements of orifices in the needles 30-33 are described (Figs. 4-9, not shown) so that the desired distribution of material is effected. The length of filter rod and number of piston-cylinder units may be varied.

Title: Safety device for a nuclear reactor

Filed: 1973-11-21
Abstract: 1450784 Controlling nuclear reactors GROUPEMENT POUR LES ACTIVITES ATOMIQUES ET AVANCEES 21 Nov 1973 [21 Nov 1972] 54120/73 Heading G6C In a nuclear reactor, e.g. a PWR, emergency control is effected by apparatus which includes an enclosure 1 internally positioned to store a pressurized fluid, e.g. inert gas, above a fluent neutron absorber, the lower part of the enclosure normally being closed but, upon attainment of certain conditions, being opened to release the absorber into a plurality of discharge conduits 11 leading to the reactor core. In one embodiment (Fig. 1) the partitions 3, 3<SP>1</SP> delimit a space 6 containing the pressurized fluid, a compartment 4 (having a flow-guiding, helical fin 4<SP>11</SP>) containing granular or powdered neutron absorber and an annular space 7 leading from compartment 4 to a lower space 5 whose bottom outlet to conduits 11 is normally closed by a brazed-in uranium pellet 2<SP>1</SP> carried by a rod 17 slidable in a bearing 19 and including fins 18. Reactor coolant emerging from the core 13 passes up the conduits 11, flows over the pellet 2<SP>1</SP> and discharges via orifices 20. In the event of depressurization in the reactor coolant circuit, pellet 2<SP>1</SP> overheats to fuse its retaining blaze and, under the influence of pressure in space 6, is ejected downwards against a stop 14. The neutron absorber is fluidized by the medium in space 6 and passes through spaces 7, 5 to the conduits 11 to be deposited in guides 12 in the core. Strainers 15 allow the fluidizing medium to escape, but retain the neutron absorber. In a second embodiment (Fig. 2) the space 6 is enclosed by a deformable wall 29 and a movable cover 31 exposed, externally, to pressure of reactor coolant. The lower space 5 is closed by a frangible membrane 24 and the conduits 11 lead to chambers 38 in which a pressure lower than that of the reactor coolant is maintained. In the case of over-pressurization of the coolant, the cover 31 effects an increase in pressure in space 6 thus causing rupture of membrane 24 and causing consequent release of the neutron absorber into the core chambers 38. Additionally, a counterweight 25 carried on a pivoted arm normally retains a plunger 28 against the action of spring 27 but, in the event of seismic or other shock, pivots to release the plunger 28 to pierce membrane 24. In a modification of the second embodiment (Fig. 3, not shown) the space 6 is delimited by space, concentric deformable walls (32, 33) which create a pressure-multiplying effect whereby the space below the membrane 24 need not be held under reduced pressure.

A fuse in an inward flow tubular filter element 16 for solids and water removal from liquids, which fuse closes the outlet 40 at a predetermined degree of contamination of water or solids comprises a spring 70 extended via wire 82 by a filter paper trigger 90 clamped at by end cap 56. As water seeps through the element during liquid filtration and contacts the trigger, the structural strength is reduced and the trigger 90 is broken by the spring 70, thus allowing spring 70 to close the outlet (Fig. 3). In the embodiment of Fig. 4, the trigger is broken at a predetermined pressure differential across the element e.g. caused by solids contamination, by the extension by the pressure differential of bellows 96 until head 102 bears against hook 89 to break the trigger 90. The inside of bellows 96 communicates with the outside of element 16.
