Abstract: 499,306. Renovating photographic films. STOCK, F. J. J. June 14, 1937, No. 16511. Convention date, July 1, 1936. [Class 98 (ii)] Scratches and other injuries are removed from either surface of the film, and the film is also protected, by treating it first with solvents of the film material, mixed with softening agents which are not solvents, to render the surface layer liquid, and thereafter, while the surface is still liquid applying a coating of hardening substances having the same optical properties as the film material. The solvent liquid preferably comprises a mixture of non-volatile and highly volatile solvents. For treating the celluloid side of a film a solvent liquid consisting of acetone mixed with dichlorhydrine, amylalcohol, camphor or triphenylphosphate may first be applied, and thereafter a coating liquid is applied consisting of collodion, celluloid or a cellulose ester, and etheralcohol. For treating the gelatine side, the solvent liquid may consist of ethylene chlorhydrine, urea and water, and the coating liquid of polyvinyl alcohol, alcohol, ethylene chlorhydrine and water. Specifications 243,752 and 486,360, [both in Class 98 (ii)], are referred to. The Specification as open to inspection under Sect. 91, states also that, alternatively to the coating liquid, a powder may be sprayed on which dissolves in the swelling agent, e.g. an acetyl cellulose film may be treated with acetone and lactic acid ethyl ester, and then sprayed with powdered acetyl cellulose.

Title: Production of neutral phosphoric acid esters
IPC: C07F9/12
Filed: 1953-06-17
Abstract: Neutral aromatic triesters of orthophosphoric acid are prepared by the reaction between a pentavalent derivative of phosphorus, P(OR)x Hal(5-x) where x=3, 4 or 5, and R is aromatic, with an aliphatic alcohol, an aromatic phenol or alcohol or an organic hydroxy acid or hydroxy ester acid of phosphorus, ROH being eliminated.  The above pentavalent P derivative may be obtained from phosphorus penta- or trichloride generally in situ. The reaction may be used to remove undesired acid organic phosphorus contaminants, e.g. pyrophosphate, from aromatic orthophosphates.  In examples, phosphorus pentachloride reacts with phenol to give triphenoxy-phosphorus dichloride which further reacts with ethanol to give triphenyl phosphate; acid organic phosphoric impurities are removed from triphenyl phosphate from other reactions by reaction with pentaphenyl phosphate to give the above product; phosphorus oxychloride reacts with phenol to give triphenyl orthophosphate contaminated with acid esters of phosphorus which are removed with phosphorus pentachloride to give triphenyl orthophosphate.

Abstract: 1377797 Rolling diaphragm gas springs combined with telescopic shock absorbers FICHTEL & SACHS AG 12 April 1972 [14 April 1971] 16845/72 Heading F2S A hydropneumatic piston-cylinder tubewithin-a-tube shock-absorber is combined with a rolling diaphragm gas spring, a non-return valve 17 allowing the gas above the liquid in the reservoir chamber 11 of the shock-absorber to flow into the gas spring chamber 1 and a non- return valve 8, 14 allowing the reverse flow. When the gas spring is heavily loaded the gas in the spring is under greater pressure than that in the shock-absorber and so passes past the piston-rod seal 8 and through a bore 14 into the reservoir chamber 11. When the load on the spring is removed, reducing the pressure of the gas in the spring below that in the shockabsorber, gas returns to the spring via the non-return valve 17. A baffle-plate 21 prevents liquid from entering the gas spring. The valve element is a section of rubber hose 19 (left-hand side of Figure) or an extension 20 of the rolling diaphragm 3 (right-hand side of Figure). The valve element is pre-stressed so that a certain excess pressure is maintained in the reservoir chamber 11.

Abstract: 1,025,787. Route setting. STANDARD TELEPHONES & CABLES Ltd. April 24, 1964 [April 26, 1963], No. 17029/64. Heading B7N. A signal, e.g. S1 or S2 is maintained in its clear condition when passed by a train until either the train has entered the second or third track sections beyond the signal or has vacated the track section in advance of the signal whereby the signal condition may be checked by a guard. Assume a route from track section il to section i6, signal S2 is energized to its clear condition by operation of relay SS2 via contacts GLU41-GLU61, indicating track sections i4-i6 are clear, contacts U41, U51 of points setting and locking supervisory relays and contact F21 of a route-type selection relay whereby signal S1 can be set to clear by operation of relay SS1 via contacts U21, GLU21, GLU31, indicating sections i2 and i3 are clear and contact SS21 of relay SS2. Signal supervisory relays SFU11 and SFU21 are energized when the signals are switched to clear and prepare hold circuits for the signal relays and in the case of signal S1 when a train enters section i1 in advance of the signal and operates a section occupation relay GL1 which releases relay GLU1 and operates relay GP1, the hold circuit is completed by energizing a second winding of relays GLU2 via contact GP11. Hence when the train enters the section i2 beyond the signal and releases relay GL2 which in turn deenergizes the first winding of relay GLU2, the relay is held by the described circuit to the second winding and relay SS1 controlling the signal is maintained energized until either the train enters section i3 and releases relay GLU3 or the train leaves section i1 whereby relay GLU2 releases when contact GP11 opens. A similar arrangement controls signal S2 except that in this case sections i4 and i5 are short sections and the signal is maintained in its clear position until either the train leaves section i3 or enters section i6.

Title: Improvements in and relating to manufacture of paints and the like
Inventor: COBBING JOHN HENRY WILLIAM
IPC: C09C3/00
Filed: 1951-07-18
Abstract: <PICT:0709020/III/1> A process of manufacturing paint or dispersions of similar character comprises pigment precipitation, extracting the precipitate as a slurry, warming the pigment slurry and a medium, and mixing and grinding them in a colour flushing vessel first at atmospheric pressure until the medium and pigment have combined, displacing most of the precipitation water which is removed, and then under vacuum whilst maintaining a temperature to promote evaporation of water; cooling the mixture and adding thinners at atmospheric pressure.  The pigment slurry and medium may be warmed to 50 DEG  C., or other suitable temperature.  The colour flushing machine, as shown in Fig. 2, is provided with a jacket 9 for steam or water to maintain the desired temperature, and a cover 3 carrying the mixing and grinding mechanism.  The bottom 6 is slightly coned to receive a conical roll 22 adapted to be rotated with its surface in contact with the bottom 6.  The roll 22 is mounted on a shaft 21 carried by a bracket 20, and provided with a spring 25 so that the roll 22 is resiliently held down to work against the bottom 6.  The bracket 20 is mounted on a shaft 13 which is rotated by suitable means.  A bevel gear wheel 18 fixed on the underside of cover 3 surrounds the shaft 13 and engages a pinion gear wheel 24 on the shaft 21; thus roll 22 revolves about its own axis as it is rotated round the bottom of the chamber, the gear ratio being such as to cause a skidding or grinding action. The bracket 20 has an extension 27 carrying scraper blades 28 and 29.  In a modification the scraper blades are carried by separate support arms, one arm being horizontal above the level of the treated material, and the other on the axis of rotation of the roll bracket 20.  After most of the water has been displaced and drained off, vacuum conditions are applied through a coupling 43, to evaporate the remaining water, the heating is then discontinued and cold water circulated in the jacket 9, atmospheric pressure is restored, and thinners are added and worked into the mass to form liquid paint which is tapped off through an outlet 12.
