Title: Transfer device
IPC: B21D43/05
Filed: 1975-12-10
Abstract: 1535744 Transfer presses KOMATSU SEISAKUSHO KK 10 Dec 1975 [10 Dec 1974] 50709/75 Heading B3H A mechanism for transmitting a feeding stroke in a transfer press comprises a pair of meshing gears 4, 5; a pair of levers 4b, 5b, each secured at a proximal end to a respective shaft 4a, 5a of the gears; a link 6 pivotally connected at a proximal end to the free end of the lever 4b and having a longitudinally extending recess 6f at an intermediate portion of its length, a first engaging member mounted on the free end of the lever 5b and engaging in the recess 6f; and a second engaging member mounted on an adjusting mechanism on the link 6 and arranged to engage a movable member of the mechanism. Actuation of the link 6 causes reciprocation of a carrier 3 along guide rods 2, which in turn reciprocates workpiece clamps along transfer bars (B), Fig. 1 (not shown), between work stations (S 1 -S 5 ). The stroke of the carrier 3 is determined by the position of the second engaging member, a roller 11, on the link 6, which engages in a slot 3a in the carrier. The roller 11 on an adjusting member 9 slidably mounted on the link and internally threaded to receive a screw rod 8. The rod is extended into a bearing box 6a 1  and it has a splined end 8b engaged in a spring loading sliding member 12. Serrations 12a on the member 12 engage serrations 6d of an end wall member 6c thereby locking the screw shaft. To adjust the position of the roller 11 a handle 15 is pushed inwardly to slide a sleeve 10 and the member 12 along the splines against the action of the spring 13, whereupon the handle is rotated.

Abstract: 1,144,817. Rolling. VERWALTUNGSGESELLSCHAFT MOELLER U NEUMANN OFFENE HANDELSGESELLSCHAFT. 16 Nov., 1966 [17 Nov., 1965], No. 51278/66. Heading B3M. A four-high rolling mill incorporates apparatus for applying predetermined bending moments to both the working and backing rolls, the moments producing uniform pressure contact between each work roll and associated backing roll. The bending moments are produced (Fig. 1, left side) by double-acting hydraulic units 15 and 20 which act on the extended roll necks 1a-4a of the rolls 1-4. The pistons of the units 20 can be locked in position. A single unit 22, which acts between a pair of adjacent chocks, may replace the units 20. Similarly, each pair of units 15 may be replaced by a single unit slidable relative to the mill housing, a yoke connecting the cylinder of the unit to the lower backing roll neck. A similar yoke 28 is shown in Fig. 4 (right side), the units 20 in this case being substituted by levers 30 whose free ends are coupled to the backing roll necks 1a 2a. By varying the position of piston rod ends 34 within slots 36 in the levers the ratio of bending moments applied to the working and the backing rolls can be controlled. In further arrangements, the mill screws are relieved of reaction forces caused by the units by inserting transverse beams between the backing roll chocks and the screws, or, alternatively, by rigidly coupling together the chocks supporting opposite ends of the backing rolls. In a final arrangement, Fig. 6, lockable hydraulic units 20 extend between the backing rolls and the opposed working rolls.

[Also in Division C3] Sulphones and polysulphones, some of which are novel, are prepared by reacting sulphur dioxide with an ethylenically unsaturated compound in the presence of a formic acid salt of a tertiary organic base and/or an addition compound of formic acid with such a salt. The novel compounds are those of the formula CH 3 SO 2 .CH 2 CH 2 .SO.CH 2 CH 2 SO 2 .CH 3  or of the formula R 1 CH(R 2 )CH 2 SO 2 CH 2 CH(R 2 )R 1 , where both R 1  are the same and are carbethoxy or cyano with both R 2  as hydrogen, or unsubstituted amido with both R 2  as hydrogen or methyl. The Specification also discloses polysulphones of formula wherein x is unspecified. The addition compounds may be prepared by reacting one mole of the base, as such or in the nascent state, with at least three moles of formic acid, as such or in the nascent state, the excess formic acid and water being removed by distillation, and the addition product isolated, optionally after a purification by distillation under reduced pressure. While the use of trimethylamine or triethylamine is preferred and exemplified, suitable bases also include aliphatically and/or cycloaliphatically substituted monoamines and polyamines, araliphatically substituted amines, and heterocyclic bases. The ethylenically unsaturated compounds may have the formula CH 2 =C(R)Y, where R is hydrogen or lower alkyl, and Y is a free or esterified carboxy group, carbonamide group, nitrile group, sulphonic acid, ester or amide group, a sulphonyl alkyl group, a vinyl sulphone group, a group or a group. The polysulphones are useful as stabilizers for plastics.

Abstract: 1469449 Screw mixers E F BACONNIER 6 Dec 1974 [7 Dec 1973] 52878/74 Heading B1C [Also in Divisions B4, B5 and B8] An extruder 1, having a reciprocatory or non-reciprocatory rotary screw 3, is provided with replaceable means 7 for metering a particulate dyestuff into plastics material being delivered from a feed hopper 4 to the extruder, the metering being effected at a rate in proportion to that of the linear retraction of a reciprocatory screw, or of the rotation of a non-reciprocatory screw. The means 7, Fig. 3, comprises a cylinder 8, containing the particulate dyestuff 17, under the compression of a piston 15 which is continuously pressurised by compressed air admitted at 16. The cylinder 7 is replaceably mounted at a bolted lug 20, Fig. 1, to a wall aperture of a chute 18 which connects the hopper 4, and extruder inlet 19. Dyestuff is discharged from the cylinder 8 into the chute 18, through radially elongate slits 11, Fig. 6, of a rotary plate 10 to which is fixed replaceably mounted blades 12, extending through the upstream ends of the slits 11 to scrape the dyestuff therethrough during rotation of the plate 10. Dyestuff issuing from the plate 10 is mixed with the material in the chute 18, by a stirrer comprising studs 30 mounted to a disc 27 rotated by an electric motor. For its rotation, the plate 10 is bolted, at 10a, to a shaft 14 extending through and out of the upstream end of the piston 15 and cylinder 8, for rotation from means effecting the retracting, or rotating movement of the screw. In the Fig. 1 embodiment, the screw 3 is reciprocated by a compressed air or hydraulic motor 6, so that during retraction of the screw, material is delivered by rotation of the screw from the extruder inlet 19 to a location 5, downstream of the screw and, during advancement of the screw, is extruded from the location 5. During the retraction of the screw, the plate 10 is rotated to deliver dyestuff into the inlet 19, by a ratchet wheel 25 on the shaft 14 which is rotated by a pawl 24 carried by an arm 23, mounted for pivoting movement on the shaft 14 which is effected by an arm 22 connected, at 21, for displacement: with the shaft 3a of the motor 6. During advancement of the screw 3, the plate 10 is stationary as the pawl 24 rides over the ratchet teeth. The ratchet wheel 25 and pawl 24 are releasably mounted on the shaft 14, at a nut 26, and the joints of the arms 22, or 23, are releasably separable to facilitate changing of the cylinder 7.  In the Fig. 7 and 8 embodiment (not shown) the screw is non-reciprocating and the shaft (14) of the plate (10) is rotated continuously by a chain or belt from the rotary drive shaft (3a) of the screw (3).

Title: Gaseous electrode for mhd generator
IPC: H02K44/10
Filed: 1976-12-21
Abstract: The installation has an electrode device in order to inject an additional plasma current into the main plasma current. The plasma-generating electrode device comprises an elongated centre electrode (22) in the interior of a hollow electrode (26), which is provided with a gas inlet (30, 32) and a gas outlet (28), as well as a voltage source, which is connected to the two electrodes (22, 26), for igniting an arc in order to generate the ionisation of the gas in the cavity (24) of the electrode device. The primary MMD magnetic field (B) has an x-component (Bx) in the longitudinal direction of the centre electrode (22), which component allows the arc to rotate in a plane at right angles to the centre electrode. In order in addition to allow the arc to move to and fro along the centre electrode (22) and hence to prevent electrode erosion at high current densities, the primary field (B) has a z-component (Bz) at right angles to the centre electrode (22). This z-component is achieved by arranging the centre electrode (22, 28) at an angle (a) with respect to the direction of the primary field (B), as a result of which additional magnetic coils can be saved for generating the z-component. <IMAGE>
