Filed: 1973-10-19
Abstract: 1451963 Rolling plates &c at speeified temperatures NIPPON STEEL CORP 19 Oct 1973 [19 Oct 1972] 48777/73 Headings B3A and B3V High toughness, high tensile strength steel plate, sheet or strip is produced from low-carbon or low-carbon low-alloy steel slab by hot-rolling with one or more reductions within a temperatture range at which recrystallization of austenite by hot rolling can occur, at least the final reduction in the temperature range being effected at a rate not less than a minimum value at the sleeted strain rate and temperature such that refinement of the austenite grains occurs at least mainly during the reduction (i.e. dynamic recrystallization), the strain rate being indicated for purposes of determining the minimum reduction by the parameter N#Ro/H, where Ro and H are respectively the radius of the reduction rolls and slab thickness before reduction in mm., and N is the speed of the rolls in r.p.m. The slab composition may include #0À30 wt. per cent C and #0À15% Nb, the temperature range being 1150-980 C. The steel may also include 0À01-0À70% Si and 0À70%-2À0% Mn, (C+Mn+Nb) # 1À35%. Minimum reductions for various temperatures and strain rates are given in Figs. 1 and 2 (not shown), the curves of Fig. 2 being used to determine the first reduction if this is effected within the temperature range after cooling from a higher temperature. Further rolling reductions may follow between 950 and 880 C. to Ar 3  with a total reduction not less than 45% of the thickness at 950 C. An alternative composition includes #0À30% C, #0À70% Si, #2À0% Mn, the temperature range being 1150-850 C. and the reduction found from the curves of Fig. 3 (not shown). Further reductions in this case may take place between 820 and 800 C. to Ar 3  with a total reduction #20% of the thickness at 820 C. After rolling the steel is cooled at 8-40 C./sec. and coiled at 680-550 C. The composition may also include N#0À1%, Al#0À8%, V#0À20%, B#0À005%, Ni#1À5%, Cu#2À0%, Cr#1À0%, Ce#0À2%, Zr#0À1%, Ti (0À15%-Nb percent). Table 1 in the Specification gives a detailed composition of three of the alloys.

Abstract: 1469799 Adjusting vehicle headlamps WESTFALISCHE METALL INDUSTRIE KG HUECK & CO 12 Nov 1974 [24 Dec 1973] 48896/74 Heading F4R [Also in Divisions F2 and G3] A valve comprises an operating member 22 movable in one direction to actuate a closure element 23, pinless hinged to pivot at 23a, 23b, and in the opposite direction to move a similar member 24 hinged at 24a, the hinged polyamide members supporting silicone rubber closures 29, 30 for ports in the valve. The closures may be loaded by springs 19, 20 and a stem 16 which carries the transverse operating pin 22 kept in light contact with a pin 13 by spring 21. The valve may be incorporated in a vehicle headlamp light range control system in which a rod 33 leads to the controlled lamp. A diaphragm 3 is secured to the pin 13 and forms chambers 1, 2 in a pressure comparison cell which receives signals at 4, 5 from axle height responsive pressure modulators (not shown) to deflect the diaphragm and actuate the valve, opening one of the closures 29, 30. The valve is attached to the cell by a rolling diaphragm 11 to form a servomotor member. A spring 12 extends the diaphragm 11 as limited by the flexible members 15. In a vacuum operated mechanism opening of closure 30 causes "follow-up" movement of the valve and rod 33 against the spring 12 with consequent reclosure of 30. Opening of closure 29 admits atmospheric air and allows extension of the spring, opposite movement of the rod 33 and reclosure of 29.

Abstract: 1,156,025. Transistor delay circuits. ALLMANNA SVENSKA ELEKTRISKA A.B. 4 Nov., 1966 [5 Nov., 1965], No. 49522/66. Heading H3T. In a timing circuit comprising a C.R. network, the charging time constant for the network is progressively varied. Diode V1 is arranged to have the same voltage drop as that across the base-emitter junction of transistor T1 so that the voltage drop across resistor R is the same as that across the reference element Z, so that varying this element will vary the charging time of capacitor C. On first switching on, transistor T2 is cut off and if R2 is large only a small voltage is applied across 1, 2 to charge the capacitor C. As charging proceeds, transistors T1, T2 become progressively conductive, thus increasing the potential across 1, 2 until T3 switches off and T4 becomes conductive to actuate relay L.

[Also in Division B7] The front wheels 3 of a load handling or lifting machine are extendible, and the position of load handling means attached to a head 9 is variable accordingly, to counteract tipping of the loaded machine. A telescopic boom 1, comprising inner and outer tubular members 10, 11 respectively, carries arms 12 supporting the load handling means on its inner member 10, pivoted thereto at 18 through a slot 11a in the outer member 11, and a parallel arm 15 ensures a constant attitude of the load handling means which may be raised or lowered by an hydraulic ram 13 mounted on a bracket 14 also attached to inner member 10 through slot 11a. The attitude of the load handling means may be varied by an hydraulic ram 19. Parallel links 20, 21 connect the outer member of the boom 1 to a rear chassis frame 7 carrying the rear wheels 4, and action of an hydraulic ram 22 advances the boom and load handling means by overcentre movement so that the pivot point 18 is moved to position A. The front wheels 3, attached to a chassis member 6 which is slidable relative to the rear chassis frame 7, are simultaneously advanced by the action of link 25, attached to link 21 and the front chassis member 6. For lighter loads, the load handling means may be further advanced by telescopic extension of the boom 1, under the action of hydraulic ram 29, without further corresponding extension of the front wheels, the pivot point 18 than being extended as far as point B. The front wheels 3 may be inturned to permit slewing movement of the machine about a lowerable turntable 5, as described in Specifications 1,015,762 and 1,262,631.

Abstract: 1,204,919. Winding apparatus. MONSANTO CO. 21 Nov., 1967, No. 52829/67. Heading D1J. A winding apparatus comprises a plurality of winding positions (only two of which are shown), each position comprising a yarn guide 8, 9 and 15 a yarn transfer means 30, a traverse (19, see Fig. 1 not shown) for traversing yarn along a yarn take up means 20 or 21 and a plurality of feed rolls 2, 3 one less in number than the yarn winding positions and positioned above the yarn guides. As shown, the apparatus has a plurality of yarn winding positions such as that at which yarn A is being wound up and a spare winding station 6, 14, 20 and 26 at one end of a row of winding positions. The winding of yarn A is transferred to the spare winding station by using doff-stick 30 to loop the yarn around the spare station's guides 6 and 14, and empty bobbin 20 as shown in dotted lines. One yarn A is then looped twice around bobbin 20 which is then swung to a position where it is driven by drive roll 26. One relatively slow rotary motion of bobbin 20 breaks the yarn still being wound on bobbin 21 and starts to wind it up on bobbin 26. Bobbin 21 is then swung away from its drive roll and is then doffed. The new empty bobbin in place of bobbin 21 then acts as the spare bobbin for the next R.H.S. bobbin (not shown) which is doffed in the above manner. The sequence is repeated until the spare empty bobbin is at the extreem R.H.S. of the row, see Fig. 3 not shown. Preferably guides 15 are J-shaped as shown and guides 6, 8 and 9 are roll guides. There may be two take-up bobbins at each winding position, see Figs. 7 and 8 not shown.
