Title: Towline System Switching Device

Abstract: 1,188,410. Towline switches. AEROJET-GENERAL CORP. 16 Aug., 1968, No. 39290/68. Heading B7L. In order to direct towline carts from the common side C of two floor towline loops A and B through a switch junction J alternately into the loops A and B (or all into either of the loops A and B), a selector plate 96 is manually selectively secured by a pin and holes arrangement to a pivoted switch plate 93 symmetrically (Fig. 8) (or angularly offset, e.g. Fig. 13), such that the towpin 18 of a first cart is guided along a slot 63 to the slot of the loop A and in its movement swings the selector and switch plates 96, 93 (by engaging the shoulder 97) through a dead centre into a position in which the slot 63 is blocked by 93a but slot 66 is opened thereby and the other shoulder 98 extends into the slot 66 so that the second cart is guided to the loop B. The selector and switch plates 96, 93 may be swung initially into either of the blocking positions manually. The chains of the loops A and B are driven in synchronism (by a common motor or synchronized motors) and their dogs alternate so as to drive alternate carts of the loops A and B as they approach and leave the common side C. The chain of the loop B descends (thus disengaging towpins 18) and runs along below the chair of the loop A in this common side C, so that only alternate carts are driven and push the others. In the switch junction J, none of the cuts are driven directly, only pushed through by the preceding cart, the slot 60 leading away sideways from the slot of the loop A at an angle to disengage the towpins from the chain. Upstream of the junction J the chain of the loop B diverges from that of loop A and rises to the slot of loop B downstream of the junction J. Storage or loading spur slots P lead from the common side C.

Title: Improvements in or relating to the decomposition of calcium sulphate in rotary kilns
IPC: C01B17/44
Filed: 1957-12-18
Abstract: In a process for the production of SO2-containing gases with or without production of cement clinker by burning a raw mix comprising calcium sulphate and a reducing-agent containing carbon in a rotary kiln of the cement-type the rate of decomposition is increased at temperatures lower than normally required by addition to the raw mix of calcium chloride and/or sodium sulphate in quantity not more than 3% wt. of each additional substance reckoned on the basis of the original mixture and such as not to cause fusing of the mixture in the rotary kiln. The reducing-agent may be coal, coke or coal-bearing shale.  The raw mix may also contain sand, clay and pyrite cinder containing free and bound oxides of Si, Al, and Fe.  Calcium chloride may be added as a solution obtained as a by-product from an ammonia soda plant.

Apparatus for forging a workpiece into a shaped body 24 having an internal recess closed at one end, comprises a pair of dies 10, 13 whose outer edges 11, 15 are arranged to contact and thus define a closed cavity 12, 14, and a plunger 18 movable in one of the dies towards the cavity for forming the recess in the workpiece. The upper die 10 is carried by a piston 4 movable within a cylinder 3 mounted on the ram 1 of a crank-operated press. Plunger 18 biased upwardly by spring 20 which also acts on an ejector and guide sleeve 21, has a piston portion 17 operating within a cylinder 16 formed in piston 4. A heated square or cylindrical steel blank is placed on die 14 and the press ram 1 operated to act through hydraulic or pneumatic fluid in cylinder 3 and press the die 10 downwards thereby shaping the outside of the workpieee. Increasing pressure acting on piston 17 then causes plunger 18 to form the recess. Upon retraction of the ram, sleeve 21 ejects the body from die cavity 12. The die 13 may be a flat plate. In another embodiment, Fig. 2, the plunger 18 operates within the lower fixed die 14 and is pressed upwardly by the excess pressure in cylinder 3 acting through pipes 9, 30 and slide valve 39. Hydraulic liquid is supplied to the cylinder 3, 31 from a air.loaded reservoir 33 through valve 34. An excess pressure valve 35 relieves the pressure when the plunger 18 has penetrated to the required depth.

[Also in Division A3] A lasted upper is prepared for the attachment of a sole by roughening the bottom with a mobile blast apparatus using a supple template which is stretched to the correct shape by clamps on an interchangeable frame and which is pressed against the bottom of the shoe. A lasted upper 8 is mounted on a shaft 2 which can be rotated through 180 degrees from a loading position (not shown) to an operative position as shown. The supple template 18, e.g. of rubber, is held by clamps 18 adjustably mounted on an interchangeable frame 16 which is carried by a box 12. The template rests on a wall of foam rubber 21 so that when the box 12 is moved towards the lasted upper the template is pressed against the bottom of the lasted upper. Blasting nozzles 26, which swivel on a shaft 24 mounted in the box 12, roughens the lasted upper and the increase in air pressure in the box 12 causes the template to bed down on to the upper. The used blasting agent is returned to the blasting apparatus 30 via a tube 32. The box 12 also contains compressed air nozzles 27 which clean the bottom of the shoe of dust and which operate at a higher pressure than the blasting nozzles so that the pressure in the box 12 is increased to stretch the template and so increase the orifice in the template.

Abstract: 1426211 Determining degree of insertion of nuclear reactor control members SIEMENS A G 30 Aug 1973 [31 Aug 1972] 40966/73 Heading G1N The degree of insertion of a nuclear reactor control member 4 in a nuclear reactor core is determined by measuring the voltage developed across a secondary winding 5 which is inductively linked in use by a portion 3 of the control member with a primary coil 6 energized at a frequency not greater than 20 c/s to diminish the influence of stray fields on the measurement. The pressure vessel 1 of a pressurized water power reactor has a stainless steel tube 2 welded thereto into which a ferromagnetic lifting rod portion 3 of the reactor control member 4 extends the degree of insertion in the tube 2 correspondingly varying the coupling between coils 5, 6 wound coaxially around the tube. A temperature stabilized A.C. source 8 supplies 6 c/s A.C. to primary 6 and the secondary winding 5 voltage is fed via leads 19 to evaluation circuit 20 in which the voltage is rectified 22, filtered 23 and then applied to amplifier 24 where it is compared with a reference on line 25. The amplifier output may be indicated on line 26 or applied to upper and lower limit signalling devices 29, 30. The number of turns of the primary winding may be increased at its ends or supplementary windings provided so as to increase the sensitivity at the upper and lower limits of the stroke of the control rod. The temperature compensation for the primary voltage can be superimposed on the signal leaving filter 23 by means of a second full-wave rectifier 27 and filter 28.
