Title: Improvements in or relating to rolling mills with reciprocating roll carriages
Inventor: BOHM KARL
IPC: B21B21/06
Filed: 1956-02-17
Abstract: 787,546. Rolling. MANNESMANN MEER AKT.-GES. Feb. 17, 1956, No. 5018/56. Class 83 (4). In a high-speed pilger rolling mill for cold rolling tubes 16, Fig. 1, the indexing mechanism for advancing and rotating the mandrel 16 is operated during a period in which the crank-shaft 3 for reciprocating the roll carriage 1 rotates between 60 and 120 degrees while the rolls are free of the work. The carriage 1 is reciprocated by connecting rods 2 and the inertia forces are balanced by dummy pistons 7 operated from the crank-shaft 3 through connecting rods 9. Rotation of the rolls is effected through stationary racks 13 and pinions 14. The workpiece 16 is supported on the mandrel 17 and gripped at one end by a saddle 32 which is rigidly connected to a feed spindle 31. Feeding and indexing movement is imparted to the saddle 32 from cams 25, 26, Fig. 2, which are driven by a shaft 20 at the same speed as the crankshaft 3 and have actuating surfaces which subtend an angle at the cam axis of between 60 and 120 degrees. The cam 25 oscillates a bell-crank 27 intermittently engaging a feed nut 30 which is continuously moved backwards along the feed spindle 31 through a variable speed gear 34 and clutch 33. A quick return is provided by a motor 36 through a clutch 38. The cam 26 reciprocates a worm 40 which co-operates with a worm-gear 41 on a spindle 42 which is coupled to the saddle 32 and to a mandrel end bearing 43 for rotating the mandrel together with the work. Return of the worm 40 to its initial position is provided by a drive 45, 46 which imparts a continuous rotation.

Abstract: 924,759. Measuring Mach numbers electrically. ELLIOTT BROS. (LONDON) Ltd. Feb. 9, 1962 [Feb. 10, 1961], No. 5135/61. Class 40 (1). An air data sensor comprises shafts 7 and 16, the angular positions of which are dependent upon the displacements of capsules 1 and 10 respectively responsive to barometric pressure (height) and static pitot pressure (air speed), the shafts being so interconnected with a shaft 20 that its displacement is Mach number dependent, the shafts being selectively coupled to electrical pick-offs 24, 25, which operate in unison and produce mutually isolated signals corresponding with the three parameters; monitoring sensing capsules 26, 29 responsive to barometric (height) and static pitot pressures respectively, together with associated capsules 1 and 10 produce mutual error signals on lines 34, 35. Shafts 7, 16 are rotated by motors 5 and 14 energized respectively from amplifiers 4 and 13 fed with displacement proportional signals from transducers 3, 2 and 12, 11, consequent rotation of shaft 20 being effected through a differential mechanism 19. Electromagnetic clutches 9, 22, 18 selectively couple the shafts to mutually geared shafts 8, 21, 17 which drive the pick-offs 24, 25. Signal cancelling movement of the core 3 of transducer 3, 2 also moves a core 28 of a transducer 27, 28, thus tending to cancel the signal from capsule 26, the mutual residual error signal appearing on line 34. Similarly, the monitoring " air speed " signal produced by transducer 30, 31 is reduced by the movement of core 12, the error signal appearing on line 35. Both error signals are used to operate disconnection means which disengage the automatic flight control system from the actual controls when the error signals exceed a predetermined value. The signals from the pick-offs 24, 25 may be used for a computer and a comparison computer of the automatic flight control system.

Title: Improvements relating to dolls and other figures
IPC: A63H3/40
Filed: 1956-02-20
Abstract: 826,628. Dolls. WALSS, W. K. Feb. 20, 1956 [Feb. 18, 1955; Sept 20, 1955], No. 5210/56. Class 132(3) A doll, Fig. 4, includes a device 5 having two operating movements, one for actuating the eyeballs and eyelids 3, 4, and the other for rotating the head; the movements may be performed separately or independently. The device consists of a button 28 pivotally mounted on a rod 29 which is itself pivoted at 30 to a plate 31 secured to the body of the doll. A bracket 36 having an opening 37 is mounted on the button and carries a pin 38 which projects through a slot in a member 39 fast with a headrotating shaft 9. The free end of the rod 29 engages with a bell-crank lever 49 connected to links 25, 26 for operating the eye mechanism 40. If the button 28 is pressed inwards, it will pivot at 30 and rock the lever 49 thus actuating the eye-mechanism. Light pressure on the button slightly to one side of the rod 29 will cause the button to turn about the rod and the head to be rotated. Firm pressure to one side of the rod causes both head and eye mechanisms to be operated, and pressure over the rod causes operation of the eye mechanism only. The eye mechanism is described in Specification 826,627. In a modification, Fig. 10. a push-button 64 is operative to cause the legs to swing backwards and forwards, in addition to operating the eye mechanism and turning the head. The plate member 77 and the leg mechanism described in Specification 826,626 has a third slotted arm 79 through which a pin 80 carried by an open frame 71 passes, a rod 66 pivoted at 67 rotatably supporting a sleeve 65 to which the frame 71 and the button 64 are attached. The free end of the rod carries a collar 70 engageable with an L-shaped lever 72 for operating the eye mechanism. The head and legs are moved when the button is pressed on one side, and the eye mechanism is operated when the collar 70 is urged against the pivoted lever 72 by means of the button.

Abstract: 779,334. Screw conveyers. KOPPERN, H., and SCHAFER, H., [trading as MASCHINENFABRIK KOPPERN & CO., KOMM-GES.]. Feb. 20, 1956 [Feb. 18, 1955], No. 5219/56. Class 78 (1). In apparatus for briquetting granular materials in a roller press 3, 4, the material is fed into the nip 2 between the rollers by a screw conveyer 6 which yields axially when the pressure exceeds a specified limit to cause temporarily a reduction in the rate of feeding the material. The shaft 7 is mounted slidably in a bearing 16 at the top of the housing 8 and is coupled directly to a geared motor 18. A flange-plate 20 on the motor casing carries three circumferentially-spaced pins 22 which pass through apertures in the bearing-plate 14 and the flange 12 of the housing 8. Each pin bears against a roller 32 mounted on the plate 14. Compression springs 26 are mounted on the lower parts of the pins and bear against retaining washers 28. A speed regulator 34 mounted on the top of the motor 18 is operated by an arm 36 which is connected by a link 38 to the flange 12. A release gate in the housing 8 may be opened by the displacement of the screw. In a modification a weighted lever system is used for loading the axially displaceable members of the feed mechanism and for adjusting the load pressure. The end of the screw 6 is provided with twin blades 5 to distribute the material uniformly over the width of the gap above the nip 2.

Title: Improvements in sliver-coiling apparatus in textile machinery
IPC: B65H67/04
Filed: 1950-03-07
Abstract: 680,470. Coiling slivers. T.M.M. (RESEARCH), Ltd., WATSON, W. H., OSBALDESTON, J., and ROCHE, J. Feb. 14, 1951 [March 7, 1950], No. 5749/50. Class 120(iii) Relates to sliver-coiling apparatus of the type in which the coiling operation is effected at least in part by the rotation of delivery mechanism in the coiler head, and which comprises means for transferring the coiler head automatically, after a timed interval sufficient for the filling of one can, to another can placed ready to receive the sliver. According to the invention, means are provided for swivelling the coiler head from one can to another without necessitating interruption of sliver output, such means being in operative relationship with, and adapted to be operated at predetermined time intervals by, means for measuring the length of sliver delivered by the feeding mechanism. As shown, Fig. 3, the coiler head is carried at the top of a column 2, rotatable in a bracket 7, and is driven by a shaft 20 coupled by gearing to the calender rolls 10 (not shown) and 11 of a carding engine. A worm wheel 29 and a counter 54 are also driven from the calender rolls. After delivery of a predetermined length of sliver into a can 52, the counter closes a switch 54a to momentarily energize a solenoid 39 which moves a spring- loaded detent 35 to release a pawl 33. The latter, which is carried on a disc 32, springs into engagement with a ratchet wheel driven by worm wheel 29 so that disc 32 is carried around for one revolution until pawl 33 engages detent 35 again. Disc 32 is integral with a shaft 42, Fig. 5, one revolution of which produces rotation of a gear 45 through 180 degrees and, via a crank pin 47, connecting rod 48 and arm 50, a swivelling through about 90 degrees of a sleeve 5 connected to column 2 so that the coiler head is swung into position over an empty can 53. Rotation of an arm 43 on shaft 42 also moves a slide 60 to oscillate a lever 62 by which the counter is re-set to zero. In a modification, the counter is replaced by a huntercog mechanism constantly driven from the calender rolls; on the impingement of the abutment cogs of the mechanism a ratchet- and-pawl clutch is operated as before to swivel the coiler head. A separate plate 96 between the cans prevents entanglement of the sliver. Specifications 636,352 and 679,027 are referred to.
