Title: Combinations of nuclear reactor fuel rods and spacers therefor
IPC: G21C3/34
Filed: 1973-03-23
Abstract: 1402197 Fuel elements SIEMENS AG 23 March 1973 [24 March 1972] 14265/73 Heading G6C Each fuel rod 2 of an assembly has at least two parallel-flanked ribs 5 disposed at intervals of less than 180 degrees about its periphery and projecting into parallel-flanked slots 6 situated in a spacer 4, the fuel rod thereby being tangentially supported. The slots 6 are each defined by a pair of projections 7, 8 on the spacer 4. Each fuel rod 2 comprises pellets of fissile material stacked within a stainless steel cladding 1. The spacer 4 is either assembled from sheet-metal strips disposed on edge or produced from a solid plate by spark erosion, the latter method being particularly suitable with metallic materials which are difficult to work, e.g. non-rusting Ni alloys. There are preferably three ribs 5 spaced apart by 120 degrees about each fuel rod 2. Any increase in diameter of the cladding 1 during operation merely has the result that the ribs 5 penetrate further into the slots 6. The fuel rods 2 are securely held fast against turning and lateral movement is positively limited to an amount necessary to permit thermal expansion. The slots 6 around each hexagonal cell of the frame 4 are formed alternately in its inner and outer surfaces. The ribs 5, as well as the projections 7, 8 defining the slots 6, are bevelled at their ends to facilitate the introduction of the fuel rods 2 into the frame 4. In an alternative, but less desirable construction, the slots are formed in the cladding and the ribs on the frame.

Title: Apparatus for cutting elongate products
IPC: B26D7/06
Filed: 1972-03-27
Abstract: 1385744 Apparatus for cutting sausages SOC LORRAINE DE PRODUITS ALIMENTAIRES 27 March 1972 [31 March 1971] 14317/72 Heading A4C [Also in Divisions B5 and B8] Apparatus for transversely cutting a plurality of products, e.g. sausages, of elongate shape and various lengths, each into at least two portions, comprises at least one substantially planar cutter 16, an endless conveyer 2 for presenting the products to the cutter, the conveyer having a generally planar upper run, means 8 on the conveyer for supporting on said upper run the products in aligned positions transverse to the direction of travel of said upper run, automatically operable positioning means 11, 12, 13 adopted to shift each product supported by the support means in a transverse direction relative to the motion of the upper run into a predetermined transverse position, and means 15 for maintaining the products in the predetermined position during the cutting operation, the cutter plane intersecting the plane of the conveyer upper run along a line substantially parallel to the direction of travel thereof. Sausages 9 are cut into two substantially equal portions by apparatus having a conveyer 2 on which are mounted support blocks 8, each provided with a recess to accommodate a sausage 9. Centring arms 11, 12, mounted in guide sleeves 22, 23 and connected by a pivoted lever 27 are provided on each support block 8. The centring arms are normally biased apart by a spring 24 so that the cups 13 carried by each arm are at their maximum separation. As each support block approaches the rotary knife 16 a shoe 25 of the centring arm 12 engages a ramp 14 and consequently both cups 13 approach the axis XY of the conveyer. The sausage 9 is centralized with respect to the axis XY by the cups, and when both cups 13 are in contact with the sausage the springs 32 on which the ramp 14 is mounted yield so that the sausage is not damaged. Before the sausage reaches the knife 16 the shoe 25 clears the ramp 14 and the cups return to their maximum spacing under the action of spring 24. As each sausage approaches the knife 16 it is engaged by two holding devices each comprising a channel member 34 carrying, on its under side, a plurality of rollers (34a), Fig. 3 (not shown). Each sausage is cut obliquely into two equal portions by a cutter mechanism comprising a motor driven rotary blade 16, the blade passing through an oblique slot 21 in the support block 8 as the latter traverses the cutting zone. The position of the blade may be adjusted by means of hand-wheels (41, 42). A safety switch (18), Fig. 1 (not shown) may be provided to de-energize the blade motor (37) if the cutter mechanism housing is opened. The apparatus may be adjusted to cut the sausage into portions of any predetermined length ratio, and a plurality of blades may be provided to cut the sausage into a corresponding number of portions.

Abstract: 997,390. Knitting-machines. N. CORAH (ST. MARGARET) Ltd. April 19, 1962 [April 21, 1961], No. 14430/61. Heading D1C. In a superposed cylinder circular knitting machine having a yarn take-up wire associated with a trapper actuated thereby mechanical means are provided which are operable when knitting a heel or toe pouch, in timed relationship with the reciprocatory movements of the needle cylinders to act on the wire to open the trapper and release the yarn before the first knitting needle in the heel or toe group draws on the yarn. An individual take-up wire 16 is provided for each backing yarn and plating yarn. Each wire is pivoted at 17 and is biased rearwardly by a spring 18 to swing backwards momentarily and allow the trapper 21, 22 to close at each reversal of the needle cylinders. Fingers 23, one for each wire, pivoted at 24 have tails 23a which may be depressed by a slide 26 operated by a cam on the upper needle cylinder 2 to move their operative ends 23a away from pins 29 mounted on the pivot blocks 19 of the wires 16. At the end of the forward swing of each wire 16 the slide 26 rises to allow the finger ends 23a to descend into abutment with each pin 29 to positively push the latter back and move the wire forward to separate the trapper elements 21, 22 and release the clamping action on the yarn passing through the eye of the wire 16. The slide 26 then moves downwards to lift the ends 23a of the fingers clear of the pins 19 before the wires 16 swing back. A cam 33 on the main control drum 5 actuates mechanism 30, 31, 32 to depress the slide 26 and render the fingers 23 inoperative when a heel or toe pouch is not being knitted. The feeder 9, which has a hole 10 (see Fig. 3) receiving a face yarn Y<SP>1</SP> and a loop 11 for receiving a backing yarn Y<SP>2</SP>, feeds the yarns during the reciprocatory knitting of a heel or toe pouch and during the rotary knitting of the leg, instep and foot bottom of a footwear article. A second yarn feeder 12 is provided to feed a third yarn Y<SP>3</SP> during the knitting of the pouches. The yarn Y<SP>2</SP> may be a nylon backing yarn, while plating yarns Y<SP>1</SP> and Y<SP>3</SP> may be of "Orlon" (Registered Trade Mark). It is stated that the edges of the forward and reverse stitch cams may be recessed (Fig. 4, not shown), to relieve the yarns of unnecessary tension during knitting.

Filed: 1967-03-30
Abstract: 1,145,196. Valves. AMERICAN METER CO. 30 March, 1967, No. 14673/67. Heading F2V. A control valve, suitable for use with domestic centralized fuel oil systems, has disposed between its inlet and outlet bores, 4 and 6 respectively, a transverse bore within which there is formed an annular projection 30, constituting a seat for a first valve member 32, 34 biased on to the seat by a spring 36. Downstream of the projection 30 is disposed a further seat 28 engageable by a second valve member 20 carried by, and disposed intermediate the ends of, a stem 18, the stem being carried by a diaphragm 10 which is downwardly biased by a spring 12. Upon a partial vacuum being created in the outlet, as by a burner, the diaphragm is caused, by the spring 12, to move downwardly and hence, via the stem 18, unseats valve member 32. Upon the pressure in the outlet exceeding a predetermined maximum the diaphragm moves against the force of spring 12 and valve member 32 becomes seated. Any further increase of pressure in the outlet, as due to leakage past valve 32, results in the diaphragm moving still further and valve 20 becoming seated.

Abstract: 925,764. Automatic phase control systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 13, 1962 [April 25, 1961], No. 14926/61. Class 40 (5). In a microwave single sideband generator with carrier suppression carrier is fed along two waveguides 1, 2 from a 3 db. coupler 3 with 90 degrees phase difference to two ferrite modulators 5, 6 with modulation applied to each in phase quadrature so that the upper (or lower) sidebands of the modulators outputs are in phase and the lower (or upper) sidebands in anti-phase. All of any unmodulated carrier is fed by polarization sensitive side arms 7, 8 to dummy loads 9, 10. If one pair of sidebands is phase shifted at 12 by +90 degrees and both pairs applied to a 3 db. coupler 4 producing a 90 degrees phase shift (lag) of the output of modulator 6 then only the lower sideband is produced at B (and the upper sideband suppressed). A variable phase shifter 11 in one waveguide 1 compensates for any phase difference variation from 90 degrees of the two carrier inputs and is automatically controlled from an amplifier 30 energized by a phase detector 25- 27. This takes inputs from both side arms 7, 8 through 10 db. couplers 24, 23 shifting one through 90 degrees at 29 so that both inputs to a 3 db. coupler 25 are normally in phase, and its two outputs rectified at 26, 27 are normally equal, and their difference taken as input to amplifier 30. (28 is an attenuator to equalize the two rectifier outputs).
