Abstract: PURPOSE: To increase the bulk density of silica gel powder to be charged into a crucible and prevent the development of fine bubbles in the resultant silica glass molded form by heat treating silica gel powder in fluidization in a rotary kiln with its maximum stack height at a specified level or higher. CONSTITUTION: First, dry silica gel 10-1000μm in particle diameter is obtained by drying at 50-200 deg.C and pulverizing wet silica gel powder obtained by a sol-gel process such as hydrolysis or gelation of e.g. a tetraalkoxysilane. Secondly, the dry silica gel powder is heat-treated under fluidization in a rotary kiln with the core pipe made of quartz. In this case, there occurs no slippage between the powder 1 and the contact surface 3 of the core pipe 2 wall, the powder 1 is raised along the wall as the core pipe 2 is rotated and then allowed to fall (as indicated by arrows) off the wall at an angle of repose or above.  To stabilize the fluid state of the powder 1, the maximum stack height of the powder 1 defined below is kept at >=75mm and the powder 1 is heated at 900-1100 deg.C (The maximum stack height is the maximum length of perpendiculars drawn from the powder surface 5 in contact with the space 4 inside the core pipe 2 toward the contact surface 3).

Abstract: PURPOSE:To make precise adjustment of the optical axis of a head lamp by connecting a voltage adjuster to a head lamp supporting mechanism so as to send a current thereto via the adjuster when the optical axis is adjusted, however, directly sending the current to a motor when the head lamp is opened up or closed in. CONSTITUTION:For closing in a head lamp, turning a retractable switch SW2 to the right turns on relays RY1 and RY3 to turn a motor 10 clockwise. A brush plate is, at the same time, turned to make a changeover switch SW1 changed to contact a point SA so that a head lamp is stopped at the closed-in position. For adjustment of lighting angle, an inclination angle indicating switch unit 40 is turned by one step so that a selector 43, for example, comes into contact with points 443 and 444. Since a relay RY2 is turned on, to drive the motor 10 clockwise at a low speed and to simultaneously turn the selector SG of a feedback switch unit 12 into contact with a contact S2. Since the relay RY1 is turned off, the lamp is stopped. Interruption of the motor performed during the adjustment of the optical axis may be achieved precisely.

Abstract: A method and apparatus are described for flanging a tubular article of a crystallizable thermoplastic polymer, particularly of a saturated linear polyester material such as polyethylene terephthalate, which has been heat-set to an elevated temperature, e.g. for producing bodies for processable food and beverage containers. The open end of the tubular body is applied to a flanging die and heated to a flanging temperature above the glass transition temperature but below the heat-set temperature of the polymer. The tubular body and the die are forced together so that the softened end of the tubular article is forced to move outwards until it abuts against a stop ring to form the flange. The residual shrinkage in the polymer material helps it to take up the precise contours of the die and to form a well-defined flange. The flanged end is then cooled, preferably to a temperature at least 20 DEG  C. below the flanging temperature, before releasing the tubular body 10 from the die.

Abstract: An assembly for filling and sealing a cavity (14) in a container (10). The assembly includes a fill passage (18) in sealing engagement with the periphery of the receiving passage (12) in the container (10). A vacuum source (24) withdraws gas from the container (10) and the assembly. Powdered material under a vacuum is supplied to a vibrating platform (44) which dispenses the material while vibrating so that the material passes through a valve (48, 52), the fill passage (18) and into the container (10). A plug magazine (26,125) stores and delivers one spherical ball (28) at a time to the fill passage (18) for being forced into the receiving passage (12) to seal the container (10). A vacuum valve (48, 52) seals the material supply from the fill passageway (18) to maintain the vacuum in the material supply when the container (10) is received. A probe (74) has a thermistor at the lower end which changes resistance in response to a change in temperature which occurs upon the material level in the container reaching the lower end of the probe (74), in response to which the vibration of the material supply platform (44) is stopped. The probe (74) is retracted and the snout (68) is moved downwardly to force a ball (28) into the receiving passage (12) to seal the container (10). The vacuum valve (52) is closed, the source of vacuum is closed and the sealed container (10) is received and replaced by another empty container.

Abstract: In swinging wire guides for generally conical finishing surfaces, the problem exists of a reliable automatic coaxial setting of the guide axes according to the particular angular position of the wire electrode in the workpiece finishing zone. As a solution, the wire guides (DF1, DF2) supported swinging on the support elements (TO1, TO2) are joined together by a coupling device, which has a guide member (FG) joined correspondingly with the support elements. The latter is set by the relative movement of the wire guides (DF1, DF2) to the desired angular position of the wire guides according to the ideal wire guide axis (D-D). Through swinging coupling gears (SK1, SK2) the angle position of the guide member (FG) is transmitted to the wire guides (DF1, DF2). These coupling gears suitably contain a jointed parallelogram (LK) and a rotary coupling member (DK) for the transmission of two swinging movement components, perpendicular to each other, in the sense of a total biaxial forced coupling of the guide member with the wire guides.

Abstract: A line interface circuit supplies energizing current for operation of a two wire communication line and couples a.c. signals between the communication line and a telephone facility. Tip and ring rails (22, 23) are resistively connected to the communication line by matched feed resistors (12, 13) in a resistance network (10) also including tip and ring taps (6, 7). Active impedance circuits (130, 140) in an a.c. signal coupling circuit (100) terminate the tip and ring rails with a predetermined impedance, via the feed resistors, in response to voltages at the tip and ring taps. Active resistance valving circuits (220, 210) in a direct current feed circuit (200) supply the communication line with energizing direct current via the tip and ring rails and feed resistors. The valving circuits may be controlled to limit current for shorter lines and the functions of the a.c. signals coupling circuit may be optimally altered in response thereto. In one example, operating band width is extended into ISDN frequencies by providing a secondary resistance network (110) with secondary feed resistors (112 113) coupling secondary tip and ring rails (122, 123) to the tip and ring rails. In this structure, the a.c. signal coupling circuit is responsive to a.c. signals at secondary tip and ring taps (106, 107) for terminating the secondary rails and a supervisory circuit 300 is responsive to the voltages at the tip and ring taps for generating supervisory signals for the telephone facility.

Abstract: A novel glycoside, 4<G>-alpha-D-glucopyranosyl rutin, is formed by a saccharide-transferring enzyme and glucoamylase in a solution which contains rutin together with glucoamylase. The 4<G>-alpha-D-glucopyranosyl rutin formed in such a solution is purified with a synthetic macroreticular resin, and crystallization in an organic solvent yields a complex crystal with the organic solvent. 4<G>-alpha-D-glucopyranosyl rutin exhibits the same molecular absorption coefficient as intact rutin has, and is readily water-soluble, substantially tasteless and odorless, and readily hydrolyzable in vivo to exhibit physiological activities inherent to rutin. These render 4<G>-alpha-D-glucopyranosyl rutin very useful as a highly-safe, natural yellow coloring agent, antioxidant, stabilizer, quality-improving agent, preventive, remedy, uv-absorbent and deterioration-preventing agent in foods, beverages, tobaccos, cigarets, feeds, pet foods, pharmaceuticals, cosmetics and plastics.
