Title: Hay-making machine
IPC: A01D78/12
Filed: 1970-07-20
Abstract: 1,261,476. Haymaking machines. MASCHINENFABRIK FAHR. AG. 20 July, 1970 [7 Aug., 1969], No. 35087/70. Heading A1F. A hay-making machine comprising one or more rake-heads has means for guiding the prongs into their operating position from their substantially horizontal transport position, the means operating as a result of centrifugal force. The rake-head 1 comprises spokes 4 rotatably mounted on an axle 2 by a hub 3, the spokes 4 being provided with doublespring prongs 10. The hub 3 is rotated on the axle 2 by means of the shaft 5 and gears 6, 7. Each prong is secured to a plate 11 which in turn is welded to a sleeve 12 rotatably mounted on the end of the spokes 4. A sliding shoe 10' is also mounted on the plate 11 to compensate for ground irregularities. Two oppositely disposed recesses 13 are provided in the sleeve 12, each having a part 13' inclined to the rotation axis of the sleeve, and into these, bolts 14 fixed to the spokes 4 engage. To minimise friction, rollers may be mounted on the ends of the bolts 14, or the recesses may be suitably coated. A disc 20 is rotatably mounted on the axle 8 supporting the ground wheel 9, and the axles 2, 8 are connected by a plate 21 containing recesses 22 to vary the displacement between them. A lever 23, displaceably guided in the projection 25, connects the disc 20 to the sleeve 12, and to make an inward movement of the sleeve possible, the lever 23 is provided with a stop 26. Springs 27 connect the plate 11 and the spoke 4. When the rake-head rotates, the sleeves 12 are forced outwardly against the force of the springs 27 by centrifugal force, and during the course of each rotation the prongs 10 are raised at a predetermined point, effected by levers 23. The sleeves 12 are drawn outwardly by these levers due to the eccentric mounting of the disc 20, and the bolts 14 move along the recesses 13, 13' thus causing the rotation of the sleeves 12 on the spokes 4. When the drive is switched off, each sleeve is drawn inwards by the springs 27 and the prongs 10 assume their transport position. In another embodiment, the springs 27 are replaced by a chain connecting the sleeve to a weight pivoted on the spoke, and the rake-head is driven by a V-belt. In a further embodiment, the spokes rotate about the same axle that supports the ground wheel, and the sleeves are adjusted by an eccentric disc, non-rotatably mounted on the axle, having a cam-track in which the levers run. The embodiment of the hay-making machine, Fig. 6, has two of these rake-heads 82, 83 mounted on a transverse support 84, the rake-heads driven by shafts 86, 87 and bevel gears. The angle of the support 84 to the direction of travel can be varied by stay bolts 94, and the space between the rake-heads can be varied by the lockable sleeves 92, 93. A plate 91 assists the formation of swaths.

The interruptions 11 may be formed above, at the level of, or somewhat below the eyepieces. The impressions 3, 30 may be simple moulded depressions in the wall of the mask. Fig. 5 shows a form of the ribs. A partition 12 may be stuck on one of the ribs or depressions, resting freely on the other rib or depression, so that the channel can be easily cleaned or disinfected.

Abstract: 1484075 Magnetic devices increasing adhesion J PINTO DOS SANTOS 12 Aug 1974 [14 Aug 1973] 35352/74 Heading B7L  The adhesive load per driving axle of a railway vehicle is increased by magnetic fields travelling along rails 11 of the conventional railway track and generated by electromagnets having a series of pairs of poles, e.g. N1, S2, lines of force between the poles of each pair acting transversely of the rails. Polyphase current is supplied to a sequence of such pole pairs carried by the vehicle in longitudinal lines such as at 4, Fig. 2, above each rail. The sets of electromagnets are supported by frames or platforms 3, 5, 6 extending between adjacent axles and themselves supported on the axle boxes 1 either directly or via resilient pads 2. The magnetic fields increase the permissible tractive and braking forces of the vehicle, not only by enhanced adhesion but optionally also by acting as a linear motor or magnetic brake.

Title: Manufacture of cigarette paper tubes
IPC: A24C5/46
Filed: 1971-07-28
Abstract: 1364847 Forming and banding cigarette spills BROWN & WILLIAMSON TOBACCO CORP 28 July 1971 [29 July 1970] 35433/71 Heading B8C [Also in Division F2] In an apparatus for forming and bundling cigarette spills, in which a web 36 is formed into a tube 44 about a rod 124 and is then cut by a knife 150 to form spills 52 which are longitudinally separated and fed to a collecting conveyer 58 by means of a conveyer 54, the spills on the collecting conveyer 58 are formed into groups by a retractable gate 60 and are fed to a mechanism 64 for bundling and banding. The web 36 of cigarette paper may be pre-printed with simulated cork-tipping regions 40, or such printing may be effected in the apparatus prior to tube-formation (Fig. 24). Alternatively, patches (4011, Figs. 25, 25a) of simulated corktipping are severed from a web (82) and glued to the cigarette paper prior to tubing. Cigarette paper-feed and tube-formation.-The web 36 is fed from a roll 34 by an endless tape 100 and is formed into a U-shape about the rod 124 by a guide 126. Glue is then applied to one edge of the web by a roller 128 and this edge is folded on to the other edge by a guide 130. The glue is then dried by a heater 132 and the tube 44 fed beneath a roller (136, Figs. 8-10) of a roller assembly 48 for flattening, the roller (136) having a peripheral ridge (138) which engages the central zone of the tube. Tube-cutting and transfer of spills to the collecting conveyer 58.-The knife 150 is carried on a rotatable shaft and co-operates with a horizontally reciprocable ledger 156 to cut the flattened tube. The operation of the knife is controlled so as to cut the tipping regions 40 medially and also cut the paper midway between the tipping regions. To this effect there is provided a photo-cell assembly 42 comprising two photocells (108, 110, Figs. 5-7), one (108) of which senses the leading edge of a tipping region 40 whilst the other (110) senses the region 40 itself. A third photo-cell (176, Fig. 14) senses the position of the knife 150. The three signals being fed to a control unit (174) for the knife. The conveyer 54 comprises three belts 216, 218, 220, Fig. 18, which take up each spill as it is severed and feed it to the collecting conveyer. Bundling and banding of spills.-The gate 60 comprises a brush (224, Figs. 19, 20) carried by a vertically reciprocable holder (226). The group of spills falls off the conveyer 58, into a shoot 238, and on to a web 245 of banding material 244 positioned across a pocket 236 in an indexing drum 234. The web 245 is fed from a roll 246 by a drive roller 248 and the leading edge of the web is gripped against a support 266 by a piston 265 prior to severing of the web by a knife 254 to form a band. A pusher 240 then pushes the group of spills 52 into the pocket 236 so as to form a bundle partially surrounded by a band. The drum 234 is then indexed to cause one end of the band to be folded against the other end thereof, and a heat-sealing head 270 bonds the ends together.
