Abstract: 899,450. Electric navigational analogue computers. BENDIX CORPORATION. Dec. 7, 1960 [Dec. 9, 1959], No. 42177/60. Class 37. The bearing # and distance L of a destination point D from a vehicle P is computed from the bearings #, #0 (and distances R, R0) of P and D from a transmitter S, respectively, the following equations being solved by the computer:- Angles # and #0 are set into resolvers 5, 20, the stators of which are rotated by a motor 10 and manually by a control 24 respectively. R and R0 are set into potentiometers 12, 14 and 27, 29 by a motor 16 and manually by a control 31 respectively. The outputs from stator windings 6, 21 representing sin #, sin #0 are multiplied by R, R0, respectively, in the potentiometers 12, 27. Voltages corresponding to R sin #, R0 sin #0 are fed to amplifier 35 and the output of the amplifier corresponding to the difference between the inputs being reduced to zero by a feed-back loop including a motor 40 which rotates the rotors 8, 23 of both synchros simultaneously through an angle # to solve equation (3) above. # is indicated at 39. Voltages corresponding to cos (# - #), cos (# - #0) will appear at resolver windings 7, 22, respectively, at the null positions and these are multiplied by R, R0 in potentiometers 14, 29, respectively, and fed to a junction 45, the voltage at which will correspond to R0 cos (# - #0) - R(# - 6) = L, L being read off across resistors 47, 46, 48.

Title: Improvements in the manufacture of metallic reservoirs
IPC: F16B5/08

Abstract: 877,792. Tanks. COMPAGNIE FRANCAISE D'ENTREPRISES, and SAGET, P. Dec. 31; 1958 [Feb. 13, 1958], No. 42233/58. Class 69 (1). [Also in Group XXII] A method of manufacturing a large metal container of ovoid or spherical shape comprises the steps of forming an inner shell and superposing a series of outer layers thereon, each layer being formed from a plurality of quadrangular plates, placed edge to edge and applied to the shell or to the preceding layer under pressure and securing the plates in this position by welding. The wall of the container may be constituted by the assembly of panels A (Fig. 2), each formed by superposing a number of metal sheets 4 welded together at 5. Alternatively there may be a number of staggered welds 6 (Fig. 3). In a further modification autogenous welding 8 (Fig. 5), may be used. The metal sheets 4 may be pressed into engagement with one another during assembly either by mechanical action or by establishing a complete or partial vacuum in the interspaces between the sheets. As shown in Fig. 6, the edge 9<SP>1</SP> of the plates 9 of each layer may be applied to an inside shell 10 by inserting wedges 11 between the edges 91 and stops 12 that are fixed to the shell. Alternatively, as shown in Fig. 8, the sheets 9 may be pressed against the shell 10 by threading them on screw-threaded rods 13 fixed to the inside sphere, nuts 14 being screwed on the rods. The holes 15 in the sheets 9 are larger in diameter than the rods 13 to leave a clearance which can be used for obtaining a partial vacuum. The holes 15 may be stopped up tightly by welding nuts 14 on the rods 13 and on to the outer surface of the wall. Alternatively, the holes 15 may be filled by welding as the different layers are put in place.

[Also in Division H2] In order to relieve the tension on the joint of two armoured pipes 8, 8<SP>1</SP> one of the end plates 12 of the connecting sleeve is fitted with a movable ring 4<SP>1</SP> to which the armouring 9<SP>1</SP> of one of the pipes 8<SP>1</SP> is secured, so that when the distance between the movable ring 4<SP>1</SP> and a fixed ring 4 is changed, the sleeve is forced to take up any stresses that are required to be transmitted by the armouring 9, 91 of the pipes. To effect the connection the pipe 8 is passed through the fixed end plate 2 which is welded in one end of the sleeve 1. Similarly, pipe 8<SP>1</SP> is passed through the plate 12 and the joint between the pipes, stripped of their armour 9, 9<SP>1</SP>, is made. The armour is folded back over each ring 4, 4<SP>1</SP> and secured by screws, bolts or by welding at 10. The sleeve 1 is then slid along towards the pipe joint to enable the ring 4 to be secured to the disc 2 by screws 5. The threaded plate 12 is screwed into its end of the sleeve 1 until it abuts the end of the ring 4 and then until tension is imposed on the armour 9, 9<SP>1</SP>. The screws 5<SP>1</SP> are inserted loosely and the spacing screws 16 turned to impose further tension on the armour, after which the screws 5<SP>1</SP> are tightened to secure the ring 4<SP>1</SP> to the plate 12. Frusto-conical and pieces 20, Fig. 2 (not shown), are provided to cover the ends of the sleeve.

Textile articles of synthetic polymers, particularly threads, are treated by immersing them while free from tension in a bath to remove impurities, heat-setting them by heating them while free from tension and thereafter subjecting them to further heat-setting treatment while they are under sufficient tension to stretch them. The bath may be an aqueous solution of ammonia, trisodium phosphate and one or more polyphosphates maintained at 50‹ to 80‹ C. The first heat-setting treatment may be effected by immersing the article while free from tension in a heated aqueous liquid at a temperature below its boiling point or at a temperature above its boiling point in an autoclave. Alternatively the first heat-setting treatment may be effected in hot air or a hot gas. The first heatsetting step may be effected at 90‹ to 150‹ C. The second heat-setting step may be effected in the case of threads and bundles of filaments by passing them through a heating zone while they are being stretched between feed and draw rolls. The heating zone may comprise a first short zone in which the filaments are heated to 220‹ to 300‹ C. and a longer zone in which they are heated from 220‹ to 250‹ C.

Air from reservoir 12 traverses lines 15, 17 to valve 14 and leaves at a selected pressure through line 18 moving piston 21 of means 19 to the left and acting under the diaphragm of relay valve 20 to first raise the diaphragm and close brake venting ports 47 and then opening the relay valve to permit reservoir air to pass to the rear brake 10 at a pressure controlled by the setting of valve 14. On actuation of pedal valve 23 reservoir pressure is admitted through lines 15, 26 to the left of piston 21, which moves to disconnect line 18 from the relay valve 20, and to chamber 41 to apply the rear brakes. The front brakes 11 are also operated. On release of pedal 25 piston 21 moves back to re-apply the selected pressure to the rear brakes. Valve 14 comprises a pressure adjusting cam rotated by hand lever 28 to vary the spring force on piston 34. Depression of the piston by the spring opens valve 37 to connect lines 17, 18, reservoir pressure then acting under the piston 34 to move it in a valve closing direction. A vent valve 35 is opened when the piston rises on movement of lever 28 to select a lower pressure.

A rolling bearing comprises one or more measuring feelers, permanently disposed between the races, for indicating the gap between the races or between one of the races and one of the rolling bodies. In Fig. 1 the feeler comprises a pin 6 having part-spherical ends 13 and 14 and supported in the gap between the rollers 3 by a leaf spring 7. The spring 7 is secured at one end to the roller cage 4 by a screw 10 and supports the pin 6 in a clearance hole 5. The pin 6 is shorter than the diameter of the roller 3 and is biased towards the race 1 by the spring 7 so that during the measuring operation it is possible to measure the gap between the end 14 and in race 2 by known means. During the working operation of the bearing, the spring 7 is clamped to the cage 4 by a screw 12 to maintain the pin 6 clear of the races 1 and 2. A further embodiment describes a feeler comprising two balls, each mounted in a clearance hole in the cage by a leaf spring, and a hole in the cage, parallel to the axis of the cage, through which a known measuring means may be passed to measure the gap between the balls. A further embodiment describes pneumatic nozzles disposed on each side of the bearing and mounted in the outer race, the outlets of the nozzles cooperating with the inner race. A further embodiment describes a feeler, e.g. electronic, pneumatic or optical, mounted in the outer race and co-operating with an axial extension of a roller bearing.
