IPC: A24B3/04
Abstract: 1,095,337. Treating tobacco. K. KORBER. June 20, 1966 [July 6, 1965], No. 28553/65. Heading A2C. [Also in Division F4] A method of packing or baling green leaves wherein green tobacco leaves are stripped or ribs, the stripped green leaf mass is separated from the ribs, is conditioned during conveyance to a preselected lower moisture content necessary for baling and is packed in bales or barrels thereafter, is characterized in that the green leaf mass is continuously turned over and loosened during the conveyance while being dried to a pre-selected moisture content and that the moisture content is automatically controlled by adjustment of the heat supply. The conditioning takes place in a conveyance drier which may be a rotating drum drier, Fig. 2 (not shown) or a pneumatic conveyer drier, Fig. 3 (not shown). When a rotating drum is used the tobacco is heated by hot air passed therethrough and also by steam heated coils within the drum. The admission of hot air is controlled in response to measurements of the moisture content of the tobacco leaf being admitted to the drum and in response to a measurement value of the hot air itself. The heater coils are controlled in response to a measurement of the moisture content of the tobacco leaving the drum. When a pneumatic conveyer drier is used, the tobacco is carried therethrough in a hot air stream controlled in response to the moisture content of the tobacco leaving the drier. In this case the tubulence of the air stream loosens the leaves. In the case of the drum drier the heated coils assist in the loosening process.

A ease comprises a sheet of material 1 formed with at least one depressed recess 2 for receiving one or more articles, e.g. a clinical sample container 3, guides overlying sheet 1 to form a slot for receiving a card 5, bearing information concerning the clinical sample and closing the open side of the recess, and stops for engaging and retaining the inserted card. As shown, in the closed position of the case, the card 5 lies beneath three flanges 4, turned over from the sheet 1, and the stops are formed by two lugs 6, struck from sheet 1. In a modification, Fig. 3 (not shown), the flanges 4 are replaced by a separate sheet of material which overlies sheet 1 and is secured thereto along three of its four edges. The separate sheet may be transparent and is formed with an aperture, which overlies the recess formed in sheet 1. The card is inserted between the two sheets and held in position to close the open side of the recess by stops in the form of tabs (11), which are cut from sheet 1 and may be snapped past adjacent edges of the separate sheet. The recesses in the sheets 1 may be tapered towards their bottoms so that a number of the sheets 1 may be stacked.

Abstract: 1,229,373. Measuring pitch of gear wheels. CARL ZEISS JENA VEB. Sept. 17, 1969, No.45803/69. Heading G1N. Apparatus for measuring the pitch of a gear wheel 1 Fig. 1 comprises two feelers 8, 9 associated with inductive displacement transducers 13, 15 carried by a head movable radially and tangentially relative to the gear wheel. The feelers are moved into the gaps on either side of one tooth on a desired measuring circle 26 and the gear 1 rotated until feeler 8 is contacted, the contact pressure being determined by the signal from transducer 13. If this differs from a desired predetermined value, the difference is amplified and fed to a servomotor which rotates the gear until the difference is eliminated. The feeler 9 is spring- loaded to make contact with the adjacent tooth and the output from transducer 15 measures the pitch at the test diameter 26. The initial distance between feelers 8, 9 is adjusted by moving feeler 9 along a guide 17 and locking it by a screw 18.

Heading H2J. The stator winding of an induction motor 2 is adapted to be short-circuited by a switch 1, and its rotor winding supplied from a frequency converter 3 which is associated with a channel 6 of a speed regulator 5. The output frequency of the regulator 5 is determined by the magnitude of a signal from generator 7 whereby the motor is accelerated to half its synchronous speed. The stator winding is then connected to the supply lines, a switch 8 being actuated to change-over the channels 6, 6<SP>1</SP>, and to alter the phase sequence of the rotor voltage. The channel 6<SP>1</SP> operates to increase the output frequency of the converter 3 from zero to half mains frequency, which is followed by phase reversal and frequency-increase over the same range. In this manner the speed-range of the motor is extended to one and a half times the synchronous speed. The output frequency of the converter 3 is synchronized with the rotor frequency when the stator winding is switched to the supply by means of a tachometer machine 9. The functions of the stator and rotor of the motor may be inter-changed.
