Title: Improvements in and relating to the setting of thermo-plastic fabrics and the like
IPC: D06C29/00
Filed: 1951-03-11
Abstract: 734,488. Finishing fabrics. BATES, E. B. June 10, 1952 [March 11, 1951], No. 774/51. Class 42 (1). Dimension stability is imparted to fabric or a fabric article made wholly or in part of a thermoplastic yarn (e.g. nylon) by submitting the fabric surface to a temporary but intimate pressure-contact in a dry atmosphere with a travelling metal surface having a temperature between 120‹ and 250‹ C. and urging it into contact with such a surface by a travelling backing. As shown, fabric travels between a first metal calender drum 10 and endless blanket 11 from an entry station E<SP>1</SP> to a discharge station D<SP>1</SP> and thence between a second metal calender drum 12 and endless blanket 13 from a second entry station E<SP>2</SP> to a discharge station D<SP>2</SP>. Calender drums 10, 11 are heated to the required temperature by steam, gas or electricity, preferably by electric heating elements as described in Specification 728,282, [Group XI], and may be thermostatically controlled. Drums 10, 11 are geared together and driven via an infinitely variable gear box 25 by an electric motor 24. Blanket guiding and driving rollers 17, 18 and 21, 22 are driven through spring- loaded friction clutches from gearing at one end of the corresponding calender drum. The blankets are given a slight over-drive, the friction clutches slipping to allow the blankets to move at the same speed as the drums. Alternatively the blankets may be under-driven, and the slipping clutches may be placed in the drive to the drums. The gearing at the said ends of the drums can be disconnected and an alternative drive engaged through gearing at the other ends of the drums, whereby the drum surface speed is greater than the blanket speed, e.g. in the ratio of 3.42 to 1, and substantial slippage occurs between the drums and the fabric; motor 24, which is a two-speed one, is operated at high speed when this alternative drive is in use. Tubular fabric is fed to the calenders over a spreader which floats between driving wheels 62, 63 carried by brackets mounted on a right- and left-hand lead screw 66 and a splined or keyed driving shaft 67, so that by rotating screw 66 by a hand wheel 85 the spacing of wheels 62, 63 can be adjusted. Shaft 67 is driven from motor 24 through a variable-speed belt drive and a two-speed gear box 77.

Title: Improvements in or relating to the production of pure dihydrostreptomycin sulphate
IPC: C07H15/238
Filed: 1950-01-13
Abstract: Pure dihydrostreptomycin sulphate is obtained from a solution of the corresponding hydrochloride prepared by the catalytic hydrogenation of a solution of streptomycin trihydrochloride calcium chloride double salt, by removing the calcium ions by the addition of ammonium carbonate either before or after hydrogenation and separating the calcium carbonate thus precipitated, the pH of the solution being greater than 7 and preferably 8.  According to the example, an aqueous solution of ammonium carbonate is added to the aqueous solution obtained by the hydrogenation of streptomycin trihydrochloride-CaCl2, until the further addition of the carbonate produces no precipitate.  After the addition of ammonia to a pH of 8, the CaCO3 is allowed to settle and then filtered off.  To the filtrate is added dilute sulphuric acid to a pH 4.5 and then ammonium sulphate.  Crystals of dihydrostreptomycin sulphate are produced by the gradual addition of two volumes of methyl alcohol to each volume of the aqueous solution.  The crystals are washed with dilute, and then with anhydrous, methyl alcohol.  The product has a potency of 850 units per m.g., is free from chloride and has less than 0.1 per cent ammonia.

Patent HU-T36269-A (HU)
Title: Load measuring system for cage lift
Inventor: SCHLEGEL URS
IPC: G01G19/12
Filed: 1985-02-13
Abstract: The load-weighing apparatus faultlessly detects even smallest load variations in the lower load range. For this purpose wire strain gauges are mounted at structural parts or components of the elevator car and these structural parts or components are subjected to bending under the load to be weighed. The wire strain gauges are interconnected to form a bridge circuit. An amplifier circuit is connected at the output side of the bridge circuit and has a higher gain in the lower load range. When an input voltage corresponding to a predetermined load occurs at the amplifier circuit, the gain of the amplifier circuit is switched to a lower value. It is thus possible to detect loads throughout a greater range of loads.

Title: Engine capable of changing number of operative cylinder
Inventor: ETOU YUKIHIRO
IPC: F02D17/02
Filed: 1980-01-07
Abstract: PURPOSE: To enhance accuracy of air-fuel ratio in recommencing full cylinder operation of engine, by detecting the temperature of an inoperative cylinder air-fuel ratio sensor, and affording the output signal of an operative cylinder air-fuel ratio sensor to an inoperative cylinder feedback means in place of the output signal of the inoperative cylinder air-fuel ratio sensor when it is detected from the same that the temperature of the inoperative cylinder air-fuel ratio sensor is lower than a predetermined value.  
     CONSTITUTION: Through comparison of the output signal of a sensor 35 for detecting the temperature of an air-fuel ratio sensor 14 and a predetermined reference signal E, a low-level signal is produced in place of a high-level signal when the air- fuel ratio sensor 14 is cooled to a temperature at which it becomes inoperable. Therefore, in case that the air-fuel ratio sensor 14 is cooled to this critical temperature as partial cylinder operation is continued long, the output of a comparator 34 is switched to the low level, so that a normally opened relay 36 is opened and at the same time a normally closed relay 37 is closed. Resultantly, the output signal of another air-fuel ratio sensor 15 is given to an input control circuit 16 in place of the output signal of sensor 14 for controlling the air-fuel ratio.

Title: Glass fiber for optical communication
Inventor: YOSHINAGA AKITOSHI
IPC: C03C3/06
Filed: 1982-01-06
Abstract: PURPOSE:To provide a fiber for optical communication which is usable stably without degrading characteristics even under exposure to neutrons by using quartz glass as a core and cladding quartz glass incorporated with a specific dopant thereon. CONSTITUTION:Pure quartz glass is used as a core and quartz glass incorporated with only the boron (<11>B) of 11 mass number as a dopant is used as a clad. A protective glass layer is formed on the outside circumference thereof. Then, even if the glass fiber is used under exposure to neutrons, the fiber is free from degradation in mechanical strength and increase in light loss, and lends itself stably to optical communication. Since the evolution of heat by the nuclear transformation effect by absorption of neutrons is obviated, the inside parts of nuclear reactors and nuclear fusion reactors are viewed directly with good safety by forming the bundle of the glass fiber.

Title: Optical recording and reproducing device
Inventor: ABE MASAYUKI
IPC: G11B7/095
Filed: 1985-01-09
Abstract: PURPOSE:To prevent the reduction of a dynamic range due to the distortion of a disk and to improve the performance and the reliability of an optical recording/reproducing device, by shifting the tilting fulcrum of a pickup toward the inner circumferential side of the disk against an optical axis in the radius direction of the disk. CONSTITUTION:An objective lens 1 is supported by a pickup 1 via a suspension 8, and the pickup 1 is put on a slider mechanism 6 so as to move toward an arrow head S of a disk. Furthermore the pickup 1 is supported so that it can turn freely round a fulcrum 5 set at the inner circumferential side of the disk with a distance M secured from an optical axis 4. The tilt of the pickup 1 is controlled by a distortion degree detecting means so that the axis 4 is set vertical to the disk surface. Then the reduction of a dynamic range l of the lens 2 can be reduced despite the distortions of the disk since the rotary fulcrum 5 of the pickup 1 is deviated toward the inside from the center of the disk. Thus the performance and the reliability are improved with an optical recording/ reproducing device.
