Title: Regular-interval mail feeding apparatus
Inventor: TAKEDA KAZUO
IPC: B07C1/02
Filed: 1989-06-28
Granted: 1994-05-03
Abstract: Abstract of the Disclosure A regular-interval mail feeding apparatus is disposed between an automatic mail discriminating/ postmarking apparatus and an automatic mail sorting apparatus, in an automatic mail handling system.  When various kinds of mails are fed at irregularly intervals from the postmarking apparatus to the feeding apparatus, it temporaling stocks the mails at its stock and sends out the stocked mails one by one at a predetermined intervals to the sorting apparatus.  When one kind of mails are fed at regular intervals, the feeding apparatus directly conveys the fed mails to the sorting apparatus without passing through the stock, by changing the mail conveying path in the feeding apparatus by using a gate member.

Granted: 1994-03-15
Abstract: ABSTRACT OF THE DISCLOSURE         There is provided a color image reading apparatus in which a directivity is given to the light emitted from a non-directional light source and when the reading position changes, the reflected light of the light emitted from the non-directional light source is reduced in substantially the same manner as the reflected light of the light emitted from a directional light source, thereby preventing the color tone deviation which occurs because the directional light source and non-directional light source are mixedly provided.

Abstract: A flocculating agent for use in water purification technology and papermaking technology is described, as well as a process of producing the flocculating agent which is the reaction product of sulphate ion-containing polymeric aluminium hydroxy chloride and one or more cationic polymers preferably selected among polyacrylic amide, polyamide amine and polyethylene imine. The most preferred cationic polymer is polyacrylic amide. The flocculating agent is produced by mixing an aqueous suspension of sulphate ion-containing aluminium polyhydroxy chloride having a solids content of 20-30 parts by weight with 0.3-60 parts by weight of cationic polymer, based upon 100 parts by weight of sulphate ion-containing aluminium polyhydroxy chloride, and by heating the mixture for 2-4 h at a temperature varying from about 80° C to the boiling of the mixture.

Abstract: A self-starting portable tool comprises a cylinder (104) in a housing (102), a piston (130) being mounted in said cylinder (104), means (164) for igniting and exploding a mixture of fuel and air in a combustion chamber (120) to drive said piston (130) to operate a working member (132), return means for causing said piston (130) to move upwardly from a lowermost position to an uppermost position of rest including outlet means (156) in said cylinder (104) between its ends. Thereby, a portion of combustion gases is forced to exhaust from said combustion chamber (120) to ambient atmosphere and a reduction in temperature of the combustion gases remaining in the combustion chamber (120) is caused. Said return means further include bumper means for initially moving said piston (130) upwardly from said lowermost position, said combustion chamber (120) above said upper face (130A) of said piston (130) being out of communication with ambient atmosphere during the further return of said piston (130) which return is substantially caused by producing an upwardly acting pressure differential on the upper and lower faces (130A, 130B) of said piston (130) induced by the reduction in temperature of the combustion gases above the upper piston face (130A).

Abstract: Reciprocating floor conveyor floor members (28) are moved by hydraulic cylinders (1, 2, 3) which are slightly tilted so as to exert a vertical component of force onto the ends of longitudinal drive beams (128, 130, 132) to which the cylinders (1, 2, 3) are connected. These beams (128, 130, 132) are made from tubular stock. Each is guided by a pair of longitudinally spaced apart bearings. Each bearing is a part of a bearing assembly (128, 130) which depends from an upper central portion of a transverse truss (80, 82). Each longitudinal drive member (128, 130, 132) is welded to a transverse drive beam (10, 12, 14) by fillet welds on each side of the longitudinal drive tube (128, 130, 132). Each such drive tube (128, 130, 132) is stiffened in the region of the weld by a short tubular insert which is rammed into the drive tube. The floor members (28) of the conveyor run on plastic slide bearings (26) which are snap fitted onto longitudinal guide beams (22). The guide beams (22) are small in size and are welded on both sides to transverse support beams (24). The construction of the slide bearings (26) permits the use of large dimension, strong, undressed fillet welds. The slide bearings (26) include wing portions (68) on each side which abut similar wing portions (68) on sideways adjacent bearings (26). The floor members (28) are held vertically relative to the bearings (26) by the engagement of bottom flanges (36, 38) within side slots (72) formed in the bearings (26). The floor members (28) add strength and stiffness to the bearings (26) and the abutting contact of the wing portions (68) causes the bearings (26) to mutually brace each other.

IPC: A61K31/415

Abstract: Described is a stable pharmaceutical composition of 3-(hydroxymethyl-5,5-diphenylhydantoin disodium phosphate ester, the prodrug of 5,5-diphenylhydantoin (phenytoin) a commonly used drug for the treatment and management of epilepsy and other types of convulsive states. It has been found that degradation of the prodrug to phenytoin can be controlled by controlling the pH of the composition. Controlling the pH to between 8.3 to 9.4 results in the production of diphenylglycinamide as the primary degradant and minimization of degradation to phenytoin. If the pH is maintained at a lower or higher value, then the degradation pattern changes, with earlier than expected product failure.
