Abstract: 754,608. Combined carding and drawing apparatus. SOC. ITALIANA CARDPEN. July 27, 1954 [Oct. 2, 1953], No. 21950/54. Classes 120 (1) and 120 (2). A porcupine drawing unit located beween the doffer and coiler mechanism of a carding machine has a rotary brush and a clearing roller to clear the porcupine roller and the two drawing roller pairs associated with it. The fibre web leaving the doffer is constricted by a condensing funnel 2 and passes between two pairs of rollers 4, 5, 6, 7, the lower of which are fluted and the upper rubber covered. The upper rollers 5, 7 are weighted by a spring acting on a saddle member (not shown) and held in operable position by a hooked handle. Higher pressure is exerted on the rollers 6, 7 than on the rollers 4, 5. In order to keep the needles of the porcupine 8 clean, the bristles of the rotary brush 11 move through them. The rollers 4, 6 are also cleaned by the brush 11 and a stationary brush 12 provides an additional cleaning action for the roller 6. A cloth covered wooden roller 10 clears the upper rollers 5, 7. This clearer roller 10 is mounted on a cover 20 that may be upwardly pivoted. When so pivoted, a cam and lever system operated by the cover 20 causes the porcupine 8 and clearer 11 to be lowered, so facilitating threading of the sliver. Quick removal and reassembly of the rollers 8, 11 is provided for by fitting muff couplings at the ends of the roller shafts.

Title: Improvements in and relating to biotin and processes of preparing the same
Filed: 1945-09-04
Abstract: The stereoisomers of the racemate of cis-2-(41-carboxy-butyl)-3 : 4-ureido-tetrahydrothiophene are separated by forming an ester of one of the component stereoisomers with an optically active alcohol, separating from the mixture the ester thus formed and decomposing the ester to obtain the pure stereoisomer of cis-2-(41-carboxybutyl)-3 : 4-ureido-tetrahydrothiophene.  Suitable optically active alcohols are the pure stereoisomers of mandelic acid and similar optically active hydroxy-carboxylic acids.  Preferably, the esters are prepared by converting the racemate of stereoisomers to a racemate of the corresponding stereoisomeric acid halides, followed by treatment with the optically active alcohol to yield the desired ester.  A detailed example is given of preparing the ester using thionylchloride. Specifications 606,188, 606,189, 606,190, 606,191, 606,192, 606,193, 606,194, 606,195, 606,196, 606,197 and 606,198 are referred to.

[Also in Division B1] Potato chips 15 passing down a channelshaped vibrating conveyer 14 are sprinkled with seasoning from a hopper 46 which has a bottom of wire mesh 57 and an agitator 73, Fig. 2, having three heart-shaped lobes 74 and carried by a shaft 69 rotated by motor 86 through a variable speed gear 87 and an arrangement of shafts and universal joints 81, 82, 90, 91. The well 47 of the hopper is preferably of transparent material such as glass or plastic and a photo-electric device 99 may give a signal or stop the conveyer 14 when the seasoning has fallen to a predetermined level 45a. The wire mesh bottom 57 is retained by spring-urged clamps 58 and can be changed without disturbing the agitator, see also Fig. 4 (not shown). The vibrating conveyer 14 has transverse rows of holes between the hopper and the discharge end through which excess seasoning falls into a container 38. The chips are discharged into a scale pan 23 which is curved in cross-section and is arranged at such a distance below the end of the conveyer 14 that the chips turn over in falling and thus receive on their uncoated sides the remaining seasoning falling from the conveyer. Alternatively or additionally, a plenum tube may be arranged under the first row of holes in the conveyer bottom, see Figs. 7 and 8 (not shown); a gentle current of air from a slit in the tube passes through the holes and blows seasoning against the underside of the chips. When a predetermined weight of chips has accumulated in the pan 23, the shafts 28, 33 are energized so that a blade 36 sweeps the curved bottom 24 of the pan, impelling the chips into a funnel 96 whence they fall into a bag 94 supported by a packaging device 92.

Title: Vertical Injection Molding Machines
IPC: B30B1/32
Filed: 1968-05-14
Abstract: 1,159,239. Injection mould closing vertically under gravity. U.S. INDUSTRIES Inc. 14 May, 1968 [21 Aug., 1967], No. 22953/68. Heading B5A. A vertically opening injection mould comprises an upper slide with an upper die member mounted thereon, means for guiding said slide between upper and lower positions, a plurality of lift cylinders with pistons for raising the slide to the upper position by hydraulic pressure, a bed with a lower die member mounted thereon to co-operate with the upper die member when the slide is in the lower position and means to allow the slide and upper die member to descend from the upper to the lower position under gravity. The upper mould 17 is rigidly attached to the upper slide 15 mounted on a structure comprising members 23, 24, 25, 26, 27 and housings 36, 37. Vertical pull rods 20, 21 are screwed into the housings 36, 37 and extend downwards through bearings 30, 31 in the bed. The lower mould 18 is mounted on a member 14 rigidly attached to the bed. Hydraulic cylinders 39 acting through pistons 41 raise the upper mould. The upper mould is lowered under gravity by allowing hydraulic fluid to exhaust from the cylinders 38, 39. When the mould halves meet, the collars 42, 43 on the lower end of the pull rods are below the clamps 59, 60 and these clamps are forced inwardly by hydraulic cylinders 62, 64 to engage the pull rods immediately above the collars. Hydraulic fluid is then forced into the enclosure 57 between the two collars 48 and 49 which, by forcing the lower mould upwards and the pull rods downwards closes the mould under pressure. To ensure that the collars on the pull rods are immediately below the clamps 59, 60 when the upper mould 60 is in its lowest position, sensing devices which actuate the mechanism in the housings 36, 37 which raises or lowers the pull rods relative to the upper mould may be mounted below the clamps. Hydraulically operated ejectors 67, 70 and cooling means 72, 73, 74, 75 are mounted in the lower and upper beds respectively. Hydraulically operated safety latches which can be moved to a position below the pull rods when the upper mould is raised, prevent inadvertent lowering of the upper mould in the event of hydraulic failure.
