Patent GB-639327-A (GB)
Title: Method of preparing opaque films from synthetic linear polyamide compositions
Filed: 1947-01-09
Abstract: Pigment-free white opaque films are formed from a solution of polymerized omega amino caproic acid in aqueous alcohol containing 5-40 per cent water, and dried at 25-70 DEG  C., the drying temperature being relatively low when the water content of the solvent is low and higher when the solvent contains more water. In example 1 a solution of 15 parts of polymerized omega amino caproic acid in a solvent consisting of 77.5 parts of ethyl alcohol and 7.5 parts of water was cast to a film and dried at 25 DEG  C. for 24 hours and then at 70 DEG  C. for 2 hours.  The film was white and opaque due to the presence of acids.  In example 2 the solvent consisted of 55 parts of ethyl alcohol and 30 parts of water and the drying temperature was 70 DEG  C.  Optimum conditions are described showing the minimum amount of water required to produce opacity under given drying conditions.  Some figures are given for optimum solvent compositions at given drying temperatures.  The opaque films may be used for coating paper, plywood, wood or plastic-cellulose laminates or as packaging material.  The Specification as open to inspection under Sect. 91 includes the use of synthetic linear polyamides generally and mentions various other solvent-non-solvent combinations which may be employed in the process.  This subject-matter does not appear in the Specification as accepted.

Title: Xylene separation
IPC: C07C7/171
Filed: 1960-01-08
Abstract: Meta-xylene is separated from a mixture of xylenes by contacting in a first zone with a recycle mixture of xylene sulphonic acids and dilute sulphuric acid, passing the mixture to a second zone where fresh sulphuric acid is added to cause selective sulphonation of m-xylene, separating from the resulting mixture a phase comprising unsulphonated oil and a phase comprising xylene sulphonic acids and sulphuric acid part of which is used as said recycle mixture and from the remainder of which m-xylene is recovered.  A xylene mixture, e.g. containing 20%- <PICT:0892330/IV (b)/1> 80% by volume of m-xylene is passed by line 1 to mixing zone 2 together with a recycle stream from reactor-settler 9 to give a recycle : feed volume ratio of 10-20 : 1. The mixture is cooled and concentrated sulphuric acid, prefer-ably oleum, added and mixed in mixing zone 6.  Sulphonation of m-xylene occurs almost spontaneously and continues in reactor-settler 9 where the mixture separates into an upper unsulphonated oil and a lower acid mixture.  The upper layer passes by line 18 to distillation tower 55 where it is separated into unsulphonated oil overhead and small amounts of polymers as bottoms.  The recycle mixture is separated from settler 9 from a pocket formed by barrier 15 and mixture for recovery of m-xylene from a pocket formed by barrier 10. This mixture is diluted to reduce the sulphuric acid concentration to about 70% and steam stripped in stripper 25 to remove any unsulphonated oil which is condensed and passed to line 18 for distillation.  The acid is heated and further diluted to give selective hydrolysis conditions, e.g. about 28% sulphuric acid concentration and 310 DEG F. and hydrolysed for about 1 1/2 hours in hydrolyser 39.  The oil product is separated and distilled to obtain 95% or better m-xylene in tower 42.  The acid layer is further hydrolysed at about 375 DEG F. for about 2 hours in hydrolyser 48 to recover other xylenes which are passed to line 18 for distillation. Sulphuric acid is recovered by line 49 for concentration.

IPC: F16J1/04
Filed: 1920-01-10
Abstract: 153,201. Goold, L. W., (Stark, O. G.). Jan. 10, 1920. Piston packing; pistons. -A piston is split or cut for a part of its length to form radially movable parts which are held apart by means of a wrist-pin or other bridging member, whereby the necessary pressure between the piston and cylinder is maintained without packing-rings &c. In one form, the piston is made from a cast. ing comprising two rings 1, 2 connected by members 3 which carry the bearings 7 for the wristpin 9. The ring 2 preferably carries two crosspieces ending in two lugs 6, and is divided into two segments by cuts 8. The bearings 7 are slightly inclined downwards so that, when the pin 9 is inserted, the two segments are forced outwards. The segments are then forced together by means of a nut and bolt in lugs 6, and while in this condition the outer surface of the piston is finished, leaving the ring 2 in a permanent state of strain. The nut and bolt are then removed and the piston inserted in the cylinder, where the expansive strain of the ring 2 maintains a close fit with the cylinder. The head 15 of the piston is fitted in the ring 2 by means of a flange 16 which may carry a flange 17 engaging a groove in the inner surface of the ring. The cuts 8 are closed by plates 18 engaging the head 15.

Title: Converter of surface acoustic wave
Inventor: SAKAMOTO NOBUYOSHI
IPC: H03H9/145
Filed: 1983-01-06
Abstract: PURPOSE:To suppress the undesired waves generated from the terminal part of an electrode by providing a triangular electrode at the terminal part of the electrode and setting the height of the triangular electrode at the level which is integer-fold as much as the wavelength in the transmitting direction. CONSTITUTION:A triangular electrode 11 is provided at the terminal part of a comb-shaped electrode finger with the length L1 which is integer-fold as much as the wavelength. The undesired waves X and Y are radiated with linear wave sources xy ans yz respectively. The waves X and Y are decomposed into surface acoustic wave oscillating electrode fingers 12 ans 22 and vertical and horizontal components X1, X2, Y1 and Y2 respectively. It can be supposed that the vertical components X1 and Y1 are radiated with linear wave sources xy2 and yy1 and that the horizontal components X2 and Y2 are radiated with linear wave sources x1y1 and y1z respectively. The sources yy1 and xy2 of the waves Y1 and X1 have an equal length to each other and are cancelled owing to a difference of transmitting distance equal to the half wavelength. While undesired waves X2 and Y2 have parallel components to each other and therefore give no effect to the filter characteristics.

Title: Permanent magnet rotor for rotating machine directly coupled with turbocharger
Inventor: ODA KEIJI
IPC: H02K1/27
Filed: 1990-01-08
Abstract: PURPOSE:To suppress increase of imbalance of rotor and to enhance reliability of shaft system by setting the thickness of a face to be fitted to the rotary shaft of a side board covering the side face of a permanent magnet equal to or longer than 1/8 of the axial length of the permanent magnet, and setting the thickness of the outer cylinder of the permanent magnet equal to or thicker than 1/2 of the outer diameter of the permanent magnet. CONSTITUTION:When the thickness of a side board 2 is set thicker than a prescribed thickness, the gap between a rotor and a rotary shaft 6a is shortened because the side board 2 inclines due to centrifugal force thus preventing the rotor from shifting and further preventing imbalance; from increasing during rotation. Furthermore, when the thickness of the outer cylinder 1 is set equal to or thicker than 1/2 of the outer diameter of a permanent magnet 3, the outer cylinder 1 is provided with sufficient strength and sufficient rigidity against inclining of the side board 2 and thereby increase of imbalance is prevented during rotation.
