Title: Method and apparatus for dividing portions of equal weight from a strand of tobacco
IPC: B21D51/26
Filed: 1970-11-17
Abstract: 1294570 Portioning tobacco MARTIN BRINKMAN AG 17 Nov 1970 [6 Dec 1969] 54675/70 Heading A2C In an apparatus for dividing portions 10 of equal weight from a strand of tobacco in a dividing passage 13, the tobacco is radially densified in a feed passage 12 as it is being fed therethrough to the dividing passage 13. The feed passage 12 comprises three solid casings 12' 1  - 12' 3  each provided with a tubular resilient sleeve 12" 1  - 12" 3  to form three resilient zones 12 1  - 12 3 . A pair of plate-type knives 30 are mounted towards the lower end of the dividing passage 13, and mounted beneath these are two sets of pivotable fingers 26 for retaining tobacco when in their closed position. The sets of fingers 26 are pivotally mounted to the lower plate 27 2  of a carriage 27, the plate 27 2  being joined by connecting rods 27 3  to an upper plate 27 1  which is suspended by measuring springs 23 from stressing devices 28 and which, as the carriage 27 descends with the continuous tobacco feed, engages auxiliary measuring springs 25 as it nears the end of its downward travel. In use, a tobacco is fed into the feed passage 12, the resilient sleeves 12" 1  - 12" 3  are subjected to suction and to atmospheric pressure alternately so as to progressively radially densify the tobacco passing through them. The downward feed of tobacco in the passage 13 is maintained by compressed air applied to an annular chamber 22. When the carriage 27 has descended a preset distance it is locked in position, the knives 30 actuated, the fingers 26 pivoted downwards to their open position, and the cut off portion 10 of tobacco is expelled onto a conveyer 50 by compressed air applied through an annular passage 49. The fingers 26 are then returned to their closed position and the rapid return of the carriage 27 upwards is effected by supplementing the action of the springs 23, 25 by the temporary actuation of the stressing devices 28. Electric contact switches together with pneumatic devices are used in the automatic operation of the apparatus.

Title: Solid state keyboard switches
IPC: H03K17/97
Filed: 1970-11-24
Abstract: 1327233 Controlled non-linear inductors ILLINOIS TOOL WORKS Inc 24 Nov 1970 [24 Nov 1969] 55892/70 Heading H3B [Also in Divisions E2 and G4] A keyboard switch comprises a yoke or keystem 18, Fig. 1, movable relative to a housing 10 and carrying two permanent magnets 14, 16 between tongues 18e, a saturable magnetic core 12 being supported by the housing so that it is normally saturated by the magnets 14, 16 but is unsaturated when the key yoke is depressed. The housing 10 has flexible projections (10b), Fig. 2 (not shown), by which it may be clipped into a board, and has a central rod 10d around which a spring 20 is placed to bias the yoke to the saturating position. After assembly, end portions 18c of the yoke are bent over to retain the yoke 4 within the housing. One or more windings 26, 28 pass through the core 12, and the core may be a press fit within the base of the housing. The core may be used with one winding as a simple saturable inductor whose impedance rises when the key is depressed. The inductor may form one arm of a bridge circuit, Fig. 8 (not shown). In Fig. 9, several switches are shown in a keyboard, each core having two windings 40, 42, which are coupled by transformer action when the key is depressed. Fig. 10 shows a BCD coded keyboard with windings 44-50 which are coupled to an A.C. source 30 in predetermined combinations when a key is depressed. Key 12 9  for example gives an output on windings 44 and 50, thus giving the binary equivalent of decimal 9. The A.C. drive windings in Fig. 10 are twisted between the cores to avoid cross-coupling between the drive and sense windings, while in Fig. 9 the drive winding threads alternate cores in one direction and the remaining cores in an opposite direction and cross-coupling is again avoided. The winding of Fig. 9 may be used in the BCD keyboard of Fig. 10, and has the advantage that the sense windings then thread all the cores in the same  direction and assembly is simplified. The core may be a ferrite, and the yoke may be nickel plated steel. The housing 10 is preferably of a one-piece plastics material such as a polycarbonate. The permanent magnets may be a barium ferrite. (For Figures see next page.)
