Title: Improvements in delivery mechanism of printing machines
IPC: B65H29/44
Filed: 1938-01-27
Abstract: 502,929. Delivery apparatus. FURNIVAL, H., and FURNIVAL, F. S. Jan. 27, 1938, No. 2575. [Class 100 (i)] A sheet-delivery apparatus which is especially applicable for delivering sensitized post-cards from printing-machines is constructed so that the cards are delivered with their printed surfaces alternately down and up by arranging in combination a flyer stick and a tape delivery and delivering the cards alternately by the two deliveries. The cards are delivered by a transfer drum 1 from the impression cylinder A of a cylinder press and are transferred by tapes 4 to tapes 5 mounted on pulleys a, a<1> supported in fixed bearings and driven by free-wheel sprocket mechanism from the drum 1. Between the tapes 5 are arranged tapes 10 mounted on pulleys carried by a reciprocating carriage B sliding on rail B<1>. The tapes 10 are driven by a chain 12 and sprocket 11 on the shaft a<2> of the pulleys a<1>. Flyer sticks 23 on a shaft 26 are arranged between the tapes, and are operated by a pinion 27 and rack 28 operated by a lever 29 and a cam 30 secured adjustably to an operating shaft driven in unison with the printing-machine. A further cam 19 on this shaft operates a lever 18, which reciprocates the carriage B and moves it to the left to a position over a pile table. As the carriage returns the tapes 10 pay out the card which is delivered printed side down. The next card is stopped by registering stops 24 and is finally delivered over the previous one with the printed side up. The levers 18, 29 are fitted with feet f, g with which co-operates a stop 31 which normally prevents the actuation of one of the levers 18 or 29 until the stop is released by the action of the other lever. When the machine is tripped a rod 36 sets the stop 31 so as to prevent the actuation of both deliveries. The stops 24 are normally raised into operative position by the action of an extension of the lever 18 upon a recess in a link 39 connected to a fever 40 on the shaft of the stops.

Title: Nuclear reactor vessels
IPC: B66C1/62
Filed: 1974-01-18
Abstract: 1453359 Fuelling reactors INTERATOM INTERNATIONALE ATOM REAKTORBAU GmbH 18 Jan 1974 [20 Jan 1973] 2596/74 Heading G6C A reactor pressure vessel has at its upper end an annular cover 2 in which a rotatable cover 3 is centrally mounted, the cover 3 having a diameter only slightly larger than that of the reactor core 4 disposed below it. In the core 4, there is indicated a number of fuel elements, breeder elements or absorber rods 5 which it is desired to displace from their respective positions in the core 4 to other portions in the core 4 and/or to one of a number of setting-down or transfer positions 6 outside the core 4. The annular chamber between the core 4 and the reactor container 1 affords space for various other components necessary for reactor operation, e.g. for inflow and outflow lines 7 and 8 for liquid metal coolant and ducts 9 for the introduction or extraction of fuel elements, &c. into and out of the reactor. The rotatable cover 3 is formed with a radially extending slot 10 in which is guided a transmission element 11 by means of which a gripper 12 can be raised and lowered by lifting tackle 13 operated by an electric motor, and opened and closed. Due to radial displacement of the lifting tackle 13 along the slot 10 and/or due to rotation of the cover 3, the gripper 12 can be caused to travel to a position over any selected rod or element 5, grip the latter and set it down at any other location within range of the space covered by the slot 10, e.g. in a setting-down position 6, from where the rod or element 5 can, if so required, be displaced by a crane-like manipulating device 14 to a location below the duct 9. As shown in Fig. 3, the manipulating device comprises lifting tackle 13 driven by an electic motor and by means of which the gripper 12 is adapted to be raised and lowered via a screw spindle 15. The gripper 12 is displaced in a guide tube 16. The displacement zone of the manipulating device is surrounded by a shielding box 17 fitted fluid-tight on the rotatable cover 3 and covering the slot 10. The lifting tackle 13 is fast on a slide 18 sliding in a guideway 19 formed in the wall of the shielding box 17, but which may alternatively be formed in the slot 10 itself. Arranged on each side of the slide 18, which is displaced by a separate electric motor drive 20, between the slide and the wall of the shielding box 17 is a bellows 21 protecting the space within the shielding box 17 against the influence of the reactor atmosphere. The bellows 21 is sealed laterally relative to the shielding box 17 by sliding seals. In order to make the manipulating device accessible for maintenance purposes, requiring removal of the shielding box 17, there is provided a separate shielding block 22 which can be pushed laterally over the slot 10 to seal off the interior of the reactor container 1.

Title: Method of sealing a turbine or compressor shaft
IPC: F01D11/04
Filed: 1965-01-21
Abstract: 1,021,410. Shaft seals. STAL-LAVAL TURBIN A.B. Jan. 21, 1965 [March 31, 1964], No. 2708/65. Addition to 954,788. Heading F2B. The method of sealing a turbine or compressor shaft claimed in the parent Specification is modified in that air is supplied to the chamber III by a fan 17 in the line 10 at a pressure which is kept constant by a pressurecontrolled valve 19 in a line 18 between the discharge and suction sides of the fan and the pressure on the suction side of the fan is also kept constant by a regulating valve 22 in the line 20. The valves 19 and 22 are controlled by the discharge pressure in line 10 and the pressure in the leakage condenser 12 respectively. Vapour saturated air from the condenser passes through a predryer 14 before being drawn by the fan 17 through a rotary dryer 16 where it is dried by by-pass air heated in a heater 23. If leakage through the gland 5 increases the valve 19 is throttled thus decreasing the pressure in condenser 12 thereby opening valve 22 to increase the air intake through line 20 and compensate for the increased air withdrawn by the fan 8. If leakage through the gland 6 increases the valve 19 is throttled but the pressure in the condenser 12 is unchanged due to the increased air flow from chamber IV through the line 11 and the setting of valve 22 is thus unaltered.

In a fabric in which weft is inserted from both edges as single picks interconnected in pairs at the edge from which they are inserted, the free ends of the picks are tucked into the same shed as the main length of the pick, and alternate tucked-in ends lie within the loop formed by two interconnected picks (and, in one form, are gripped between the loop and the end warp thread), the intervening tucked-in ends lying between successive loops. The wefts are laid by two weft inserting needles mounted at opposite sides of the loom, which cross the loom in close succession, the shed being changed between them; the operational cycle includes traverses in which one or both needles do not lay weft. Mechanism. The tucked-in ends are formed by means of a weft catcher, Fig. 4A, whose jaws 32, 34 open to allow the weft inserter 14 to pass between them as it emerges from the shed; the jaws then close to embrace the weft thread (without gripping it), the inserter 14 being recessed to enable the depending end 40 of the upper jaw to pass behind the weft. As the weft inserter reverses its movement and re-enters the shed, the weft catcher turns about its vertical shaft to bring the loop formed round the end 40 near to the selvedge. When the weft inserter has laid a short length of weft in the shed, a pin 18, Fig. 3E, penetrating the warp inwards of the selvedge descends, whereupon the weft is cut by a blade 20; the weft inserter completes its travel without laying weft. Whilst these actions occur, the weft 42, Fig. 4A, of the other inserter is held clear as a consequence of being lifted by the upper jaw 32 as the jaws opened; as this weft is being laid in the shed to form the second of a pair of connected, it slides off the jaw and engages round the tucked-in loop still held by the jaw 40, which then opens to release it. The tucked-in ends lying between weft loops are longer than those lying within weft loops, this being achieved by shogging the cutter 20.

Title: Forming protective films on metals
IPC: C23F11/00
Filed: 1957-01-29
Abstract: A ferrous metal surface having a nitrogen concentration of at least 0.003% is made resistant to attack by corrosive liquid metals by contacting it with a liquid metal having dissolved therein at least 0.5 p.p.m. of zirconium, titanium or hafnium, at a temperature at which the nitrogen is available for reaction with said dissolved metal at the surface, to form a protective layer of nitride of the dissolved metal on said surface.  The surface may be in the form of a container for corrosive liquid metals used for transferring heat within power generating apparatus, particularly for liquid metals used as carrying media for fissile or fertile materials in nuclear reactors.  Protection is stated to be afforded against zinc, cadmium, mercury, gallium, indium, thallium, tin, lead, bismuth, antimony and their alloys. Examplified treatment media are bismuth-zirconium, bismuth-zirconium-magnesium, bismuth-titanium, and mercury-titanium-magnesium.  The ferrous metal surface may be a steel having a high concentration of metal nitrides (e.g. nitrides of silicon, chromium, aluminium or vanadium), which are less stable than the nitride of zirconium &c.  If desired, the nitrogen content of the surface may be increased before treatment, e.g. by subjecting the surface to the action of cracked ammonia at 1000 DEG -1200 DEG F.
