Abstract: 413,486. Tobacco-stemming machines. TRIGGS, W. W., 57, Lincoln's Inn Fields London.-(Standard Tobacco Stemmer Co. ; 511, 5th Avenue, New York, U.S.A.) June 15, 1933, No. 17079. [Class 130.] Tobacco leaves or leaf portions are delivered to one end of an annular space between relatively rotatable members carrying shredding-elements, and the leaf and stem fragments are discharged by a fan through a common outlet into a device for separating the leaf fragments from the stem fragments. As shown in Figs. 1 and 2, the leaves L are delivered through a shoot 19 to the annular space between a fixed shell 15 which carries pins 16, and a rotating shell 23 which carries pins 24. The pins 16 are square and the pins 24 are rectangular and are set with their longer sides inclined to the direction of movement to impart to the stem and leaf fragments movement towards the delivery part of the annular space. A fan 30 is provided in an extension 26 of the shell 15, which is closed from the annular space between the shells 15, 23 except at the delivery part. The fan is closed in by a disc 29 which is provided with a regulable air inlet, and forces the stem and leaf fragments through a pipe 37 in which is mounted an adjustable baffle 42. The heavy stem fragments S drop from the first section of a chamber 38, while the leaf fragments L<1> are blown over a partition 39, and dust D passes through a screen 41 carried by a partition 40. In a modified construction, a common feeding- device introduces the tobacco leaves into the annular spaces between the relatively rotatable members of two shredding-units, and the extensions 26 are provided at their lower parts with screened outlets to permit dust and small particles to escape. Two baffles are mounted in the discharge pipe to gather long and short stems, whilst the leaf fragments are blown over both baffles. In the construction shown in Fig. 5, the leaves are fed by a belt A to beaters 81 which clear the butt ends of the stems, and drop them down the shoot 19. The leaves L are then fed by belts C to the stripping- machine, the stripped tobacco falling into a receptacle E, whilst the stems are delivered to a receptacle F. The leaf fragments, after being shredded, are delivered by the fan into the receptacle E, whilst the stem fragments fall through an outlet 82 on to a belt 83, which carries them into the receptacle F.

Title: Improvements relating to ion-exchange processes and apparatus
Inventor: TYE FRANK LAURENCE
IPC: B01J49/00
Filed: 1956-06-14
Abstract: The degree of exhaustion of a mass of ion-exchange material is determined by measuring the resistance of an ion-exchange membrane situated in a part of the liquid which has passed through all or most of the mass.  The change of conductivity of such a membrane is said to be greater than that of the mass itself, the resistive measurement of which was disclosed in Specification 714,642 [Group XXXVI].  The ion-exchange material may be in the form of a mass regenerated as a whole from time to time or of a mass moving in a step-by-step fashion so that spent material is removed from one end of the mass, regenerated and returned to the other end. The invention may be applied to cyclic exchange processes for water treatment in which cation exchange material charged with sodium or hydrogen ions is immersed in a part of the water which has passed through all or most of the mass the change in resistance of the membrane being used to operate an indicator or to initiate regeneration.  The invention can also be applied to cyclic anion exchange processes and the membrane must be capable of removing or exchanging anions from the water under treatment but not from the treated water.  Thus if the ion exchange material has weakly basic groups the membrane may be strongly basic and charged with bicarbonate ions or weakly basic and in free base form.  If the ion-exchange material is strongly basic the ions may be weakly basic both material and membrane being charged with hydroxyl ions.  The specification describes apparatus for illustrating the charge in electrical conductivity of a membrane used in a water softening process.  A piece of cation-exchange resin membrane 2 inches square is arranged in a vertical position near the bottom of a 3 inch diameter glass tube.  Platinum electrodes are connected along the whole length of two opposite edges of the membrane and in one arm of a wheatstone bridge circuit.  The bottom of the tube was closed by a stainless steel gauge and the tube fitted to a depth of 2 feet 6 inches with cation exchange resin.  The lower edge of the membrane was 1 inch from the bottom of the tube.  The bed of granules was activated with one gallon of 10% hydrochloric acid solution and the excess acid washed off with water.  This activation also charged the membrane with exchangeable ions.  Specifications 719,315 [Group III] 720,002 and 721,161 [Group III] also are referred to.

Filed: 1940-12-11
Abstract: 544,687. Grinding. AKTIEBOLAGET SVENSKA KULLAGERFABRIKEN. Dec. 11, 1940, No. 17569. Convention date, Dec. 13, 1939. [Class 60] In a grinding machine comprising a pivoted or reciprocating periodically-movable head for the work or tool, and means for feeding the tool relatively to the work, the feeding-means is driven by the head in such a manner that the speed is varied in accordance with the variations in the speed of the head. The arrangement reduces the feed at the ends of the stroke of the head, thereby causing the tool to make a more uniform cut, and preventing excessive pressure between the work and tool. The mechanism shown in Fig. 2 is included in a machine for grinding spherical bearing-rollers, and comprises an oscillating head 4 carrying cross-slides carrying the work in position for engaging a grinding-wheel on a slide which is advanced by a feed-screw 54. The head is oscillated by means of ropes 27 which are connected to a pulley 28 on the head and to crank-pins 25, 26 on a shaft 24 geared to a driving-shaft 21, the shafts being mounted in a pivoted casing 29 which is connected to a spring for tensioning the ropes. The feed-screw 54 is geared to a shaft 34 provided with pulleys 33, 37 engaging a rope 32 which is secured at the ends to the head, and passes over tension-pulleys 35, 36. The pulleys 33, 37 are provided with free-wheels so arranged that the cord transmits uni-directional movement to the shaft 34, and consequently to the feed-screw, the speed of the latter varying in accordance with that of the head. The mechanism may be provided with the automatic stop-device described in Specification 529,449 for stopping feed when the work has been ground to the required dimension. The stop-device comprises a gauging-finger for closing the circuit of a solenoid 57 and thereby permitting a lever 59 to release a clutch 62 in the train of gearing between the shaft 34 and feed-screw 54. The mechanism shown in Figs 7 and 8 is included in a machine for grinding the interior of a ball-race 70 by means of a grinding- wheel 75 carried by a slide 76 on a head 75 which oscillates on a vertical pivot 4. The feedscrew 78 for the slide 76 is now provided with a ratchet-wheel 89 co-operating with pawls 87, 88 on slides 86, 83 which are guided by a casing 84 on the head. The slides are inter-geared by a pinion, and the slide 83 is provided with a roller 82 co-operating with a stationary, inclined track 81. During oscillation of the head, the slides are reciprocated in opposite directions, the pawls are alternately effective, and unidirectional movement is imparted to the feedscrew, the speed of the latter varying in accordance with that of the head.
