Patent JP-H01179032-A (JP)
Title: Color printer
Inventor: HARAGUCHI SHIGETERU
IPC: G03B27/58
Filed: 1988-01-01
Abstract: PURPOSE:To easily change the printing frame of an exposure part in a well- lighted room by relatively moving a photosensitive material and the printing frame so that they may separate and providing a light shielding means for shielding the photosensitive material from light so that it can freely go in and out in a formed space. CONSTITUTION:When the motor 87 of an elevating mechanism 85 is driven, a driving shaft 93 is rotated through a belt 91 and a nut 94 descends. Then a printing frame board 77 descends and the wide space L is formed between the printing frame 98 of the printing frame board 77 and photographic paper. When a connecting shaft 108 is driven by driving a motor 110, the pulley 107 of a take-up shaft 106 integrally rotates to pull a belt 105. A rotary cylinder 103 is rotated and the light shielding film 101 provided on the belt 105 is pulled out to the space L formed between the printing frame 98 and the photographic paper, then the light shielding film 101 shields the photographic paper from the light. Thus, an operation for changing the printing frame 98 in the light room can be possible and errors in selecting the printing frame 98 are removed.

Title: Improvements in or relating to methods and apparatus for removing burrs or the like from workpieces
Inventor: GOODWIN FREDERICK LEWIS
IPC: B23D79/00
Filed: 1962-01-02
Abstract: 969,546. Deburring by cavitation. ROLLS ROYCE Ltd. Dec. 31, 1962 [Jan. 2, 1962], No. 196/62. Heading B3V. [Also in Division B5] A method of removing burrs or the like from a workpiece comprises immersing the workpiece in a liquid and thereafter creating pressure waves in said liquid in such manner that the liquid adjacent the workpiece oscillates relative thereto, the motion of the liquid relative to the workpiece attaining sufficient speed to produce cavitation in the vicinity of the workpiece. The workpiece 3, e.g. a turbine blade, is secured in a movable support assembly 2 and positioned in a tank 1 of water. A transducer e.g. a magnetostrictive stack 5, is resiliently supported at its mid-point on a bracket 4 such that its lower tip 6 is below the surface of the water and approximately 0.050 above the blade 3. Coils 7, 9 are wound around the lower and upper portions of the stack and are connected to an oscillator 8 and D.C. supply respectively. In operation the coil 9 is energized by the D.C. supply and the oscillator 8 energizes the coil 7 with A.C. at a frequency of 8-16 kc/s. to produce an amplitude of vibration at the tip 6 of 0.003 peakto-peak which produces intense cavitation effects around the blade tip to remove projecting burrs therefrom. During vibration of the tip the support 2 is moved to subject the whole face of the blade to the cavitation effects to effect complete deburring. The transducer may be of the piezo-electric type and the cavitation effect varied by the addition of a wetting agent. The mechanical energy delivered by the transducer may be concentrated by using a " velocity transformer," i.e. an exponentially tapered stud at its tip. The workpiece may be arranged to vibrate in the liquid.

Title: Improvements in or relating to apparatus for seasoning wood
IPC: B27K5/00
Filed: 1923-01-03
Abstract: 192,372. Lyon, G. Jan. 27, 1922, [Convention date]. Fluid-actuated valves. - In apparatus for seasoning wood by means of ozone, electricallyoperated valves, governed by a clock, are employed for filling the chamber with dry air, exhausting the chamber, admitting ozone, restoring atmospheric pressure, ozonizing and circulating the air in the chamber, and allowing to stand at rest, in continuous cycles. The chamber 2 is connected with a mercury manometer 10<1>, exhaust pipe 6, source of dry air 3, ozonizer 5, by pipes 10, 7, 4, and 8 and 9, respectiveyl, the passage of gas along these pipes being controlled by valve apparatus 23, 20, 19, 22. The clock 1 is provided with a wheel 25, Fig. 3, having a rim perforated with ten rows of holes 30 sixty in a row for the reception of contact pins. The order and duration of operation of the various valves are determined by suitably placing the pins in the holes 30. A valve-operating mechanism is shown in Fig. 4. When an electromagnet 44 is energized the disc 45 is drawn away from the end of an evacuated pipe 45<1>, and air is admitted below a piston 48. The space 46 is in communication with exhausting means so that the piston rises and carries with it a valve 49. The bellows 36 are thereupon evacuated and the lever 51 descends rocking a lever 52 about its pivot. A stem 42<1> and attached piston 43 are thus moved away from the orifice 42 of a pipe 40. Communication is thus made between a pipe 38 and a pipe connected to the space a. Specification 182,504, [Class 140, Waterproof &c. fabrics], is referred to
Patent GB-980968-A (GB)
Title: Foamed compositions containing polyvinyl chloride
Inventor: BUIST JACK MITCHELL
IPC: C08J9/06
Filed: 1962-01-04
Abstract: Foamed polyvinylchloride compositions are made by mixing finely divided polyvinyl chloride, a plasticizer, a prepolymer having free isocyanate groups and water, then heating the mixture.  The prepolymer, which may be used in amounts up to 40%, may be derived from the reaction of di- or tri-isocyanates with a polyol, e.g. a polyether or polyester with totylene di- or tri-isocyanate, hexamethylene or naphthalene di-isocyanate or 4,4-di-isocyanate diphenyl methane.  Specified plasticizers, e.g. polypropylene adipate and dibutyl phthalate, may be used in amounts 0.3-2.5 parts per part of P.V.C.  Sufficient water may be added to avoid free isocyanate groups in the finished composition whilst the viscosity of the composition may be increased by incorporating polyurethane forming substances such as polyhydroxy compounds, polyethers and polyesters. The composition may be heated to 80 DEG  to 150 DEG  C. Polyoxyalkylene polysiloxane block copolymers may be added to the composition before foaming.  The isocyanate-water reaction may be catalysed by organo-tin derivatives or tertiary amines whilst blowing agents such as CCl3F and C2Cl3F3 may be included.  In the example a prepolymer formed from tolylene di-isocyanate and tri-methylol propane-propylene oxide adduct of M.W. 310 is used together with a trimethylol propane-propylene oxide adduct to increase the viscosity of the mixture.  Specification 928,325 is referred to.

Abstract: 920,788. Clutch control. SPERRY RAND CORPORATION. Jan. 9, 1961 [Jan. 8, 1960], No. 797/61. Class 80 (2). A circuit for energizing either a first load 12 or a second load 13, such as a clutch and brake in a mechanically driven press, electronic computer or. adding machine, at high initial and subsequent lower rates, comprises two bi-stable devices, such as gas tubes 230, 240, 250, 260 for each load, the tubes being connected such that energization of one tube extinguishes the others. An input signal at a terminal 27 fires tube 230 and energizes a clutch coil 12 through a resistor 341, a conductor 34 from which drops to a low potential which is transmitted through capacitors 371, 372, 572, 581, 583 to the anode circuit of tube 260, thus extinguishing it and releasing a brake coil 13. The same negative pulse is transmitted through an R.C. network 352, 351 to the grid of tube 240 which prevents it from firing for a short interval. Tube 260 extinguishing causes a diode 474 to block, thus raising the junction voltage of a pair of resistors 472, 473 to allow tube 240 to conduct when the internal has expired, thus energizing rail 12 at a lower rate through a resistor 36. Tube 240 firing supplies a negative pulse through capacitors 383, 381, 371 to the anode of tube 230 thus extinguishing it. A similar sequence follows when a signal appears on a brake terminal 26. To avoid " fight " between the clutch and brake circuit should signals be applied to terminals 26, 27, simultaneously, the two delay circuits have different time constants. The gas tubes may be multi-grid thyratrons.
