Title: Improvements in bearing devices
IPC: F16C35/04
Filed: 1955-02-04
Abstract: 764,639. Ball bearings. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 4, 1955 [Feb. 8, 1954], No. 3343/55. Class 12 (1). A magnetic drum 10 is mounted on a fixed hollow shaft 30 by ball bearings 14, 18, and radial play in the bearings is substantially eliminated by expansion devices 34, 35 located within the shaft 30. Each expansion device comprises two pairs of curved discs 38 which, when axially compressed by a nut and bolt assembly 36, 39, expand radially and cause the shaft and inner bearing race similarly to expand radially. After one expansion device has produced interference between the shaft and inner race, it is slackened off a noted amount. The other expansion device is then adjusted to produce interference with the other bearing, whereupon re-adjustment of the first device by the noted amount produces approximately the same pressure on each bearing. Further adjustment is then effected to reduce internal clearances in the bearings. Greaseretaining members are provided each side of the bearings. Rubber sealing rings are located in grooves in the outer peripheries of the grease retainers. During operation, oil centrifuges out of the grease and provides oil reservoirs each side of the bearings.

Abstract: 1,244,042. Producing Kanamycin B. MEIJI SEIKA KAISHA Ltd. 13 Aug., 1968, No. 3492/71. Divided out of 1,244,041. Heading C2A. The antibiotic 2<SP>1</SP>-amino-2<SP>1</SP>-deoxy-kanamycin (Kanamycin B) having the formula is produced in improved yield by cultivating one of the mutants identified as A.T.C.C. 21260, A.T.C.C. 21259, A.T.C.C. 21261 and A.T.C.C. 21268 of Streptomyces kanamyceticus A.T.C.C. 21252 under aerobic conditions in a culture medium containing assimilable sources of carbon and nitrogen until 2<SP>1</SP>-amino-2<SP>1</SP>-deoxy-kanamycin accumulates in the culture broth and then recovering it therefrom. The mutant strain A.T.C.C. 21259 is produced by treating a liquid culture of the parent strain Streptomyces kanamyceticus A.T.C.C. 21252 with 50 mcg./ml. of nitrogen mustard and cultivating the treated organisms on a plate of Czapek medium containing 3% of 3-amino glucose in place of 3% of sucrose; three types of colonies grow, distinguished by size, the required mutant being isolated from the large colonies only. Strain A.T.C.C. 21260 is produced by treating the parent strain with 500 mcg./ml. of nitrogen mustard and selecting organisms which showed essential demand for deoxystreptamine for growth on Czapek medium. Strains A.T.C.C. 21261 and 21268 are produced by subjecting the parent strain to U.V. irradiation and selecting strains which could grow on starch Czapek agar but not on a medium containing dulcitol as the only carbon source (dulcitol-mineral agar). All of these mutants, unlike the parent strain, have little or no ability to utilize xylose. The antibiotic is isolated from the culture after filtering off the mycelium by absorption on and elution from cation exchange resin, e.g. with ammonia solution, extracting the alkaline solution with an immiscible organic solvent, e.g. n. butanol, which preferably contains lauric or para-toluene sulphonic acid or benzaldehyde, re-extracting into acidified water, decolorizing with charcoal, concentrating and then freezedrying, and finally recrystallizing from aqueous dimethylformamide.

Title: Imprvements in or relating to web feeding, registering, and cutting apparatus
IPC: A24D1/16
Filed: 1965-01-27
Abstract: 1,064,260. Feeding webs. AMERICAN MACHINE & FOUNDRY CO. Jan. 27, 1965 [Feb. 6, 1964], No. 3588/65. Heading B6B. In a mechanism for feeding and registering continuous webs such as webs of cigar bands (W, Fig. 3) which occur in a repetitious printed and cut shape arrangement, a web contour sensing device having contour sensing arms is provided, which senses and positions each band for cutting and delivering to a banding and/or wrapping station. The sensing device may be the sole means for sensing the web in the longitudinal registering mechanism, but may be associated with a photo-electric type of web registering device which is maintained in an inoperative condition until that portion of the web to be registered has been sensed by the contour sensing device, whereupon the photo-electric cell mechanism is energized and made ready to register that particular portion of the web. Fig. 1 illustrates apparatus having a web contour sensing device S used in conjunction with a photo-electric detector P. The web W is advanced by a pair of nip rollers 10, 12, passes over a dancer roller 18 and an idler roller 22, and is further advanced by nip rollers 24, 26 to a cam-operated severing device 56. The pairs of nip rollers have a common drive (Figs. 2 and 4) which includes a motor (72), a clutch (72C) and a brake (72B). The sensing device S includes a microswitch (80, Fig. 6) pivotally supported on a bolt 82 and has two sensing fingers (88 and 90), finger (90) being pivotally mounted at (92) to the microswitch housing for movement relative to the finger (88). The photo-electric detector P includes a light source 66 and a photo-electric cell 68. In operation, during the major portion of each web feeding cycle, the photo-electric detector P remains inactive so that a control relay switch (122, Fig. 4) is de-energized. Contacts (126) therefore remain closed and the clutch (72C) engaged to transmit the drive to the nip rollers 10, 12 and 24, 26. When the shoes 94 on the fingers 88 and 90 sense the widest portion of the web (Fig. 3) the contacts of microswitch (80, Fig. 4) will be closed thereby energizing the photo-electric detector P. The photo-electric cell will fire when the focal point (77, Fig. 3) of the photoelectric detector coincides with the translucent area (79) of the web after the opaque area (78). This causes energization of relay (122) thereby engaging brake (72B) and disengaging clutch (72C). The web is thereby registered for cut off and delivery to the banding and wrapping station. The web feed is resumed immediately after cut off by a cam-operated switch (128) interrupting the supply to the photo-electric detector P. The cam (132) of switch (128) is mounted on the shaft 64 of the cam 116 of the severing device 56, Fig. 1. In alternative embodiments (Figs. 5 and 7-13), the photoelectric detector P is not used, and the microswitch in the detector S is of a double-pole type. One pole is used for the clutch circuit and the other for the brake circuit.

Abstract: 1,199,263. Methanol. CHEMICAL CONSTRUCTION CORP. 22 Jan., 1969 [31 Jan., 1968], No. 3693/69. Heading C2C. [Also in Division C5] Methanol is produced by a process in which a gas stream from catalytic methanol synthesis is cooled at elevated pressure to condense crude methanol which is separated from residual gas, which residual gas is divided into high-pressure purge gas and a recycle gas to the synthesis, the purge gas is expanded to intermediate pressure through an aspirator, the crude methanol is distilled under reduced pressure to form a methanol stream and a low-pressure overhead stream of volatile, combustible compounds and this lowpressure stream is inducted by the aspirator to form with the purge gas a fuel gas of intermediate pressure. A gas phase may be evolved by reducing the pressure of the crude methanol to intermediate pressure and said gas phase may be added to the fuel gas at intermediate pressure. The crude methanol may be initially distilled at reduced pressure by water extractive distillation and the low pressure stream may be produced from the extractive distillation of said crude methanol. The resulting fuel gas may be used for combustion in the catalytic steam reforming of a hydrocarbon to produce a gas stream for the methanol synthesis in a catalytic reformer.
