Title: Surface active agents and compositions containing the same
IPC: C11D1/34
Filed: 1969-03-05
Abstract: 1,236,703. Vicinal diols and derivatives. MONSANTO CO. 5 March, 1969 [5 March, 1968], No. 11821/69. Heading C2C. [Also in Division C5] Individual C 14-20  α-olefins are isomerized to mixtures of internal C 14-20  olefins, thereafter reacted with formic acid and hydrogen peroxide to form the internal isomeric vicinal diols, and then ethoxylated by reacting with 5-6 moles of ethylene oxide. Mixtures of individual C 14-20  α-olefins may be converted to mixtures of ethoxylated vicinal diols in the same way and in addition mixtures of individual C 14-20  internal isomeric vicinal diols may also be ethoxylated. The C 14  internal vicinal diolethylene oxide condensation product (5E.O), and mixtures of C 15-20  internal vicinal diolethylene oxide condensation products obtained by blending mixtures of individual vicinal diols may thereafter be sulphated by heating at 120-125‹ C. with sulphamic acid after neutralizing the excess acid with ethanolamine. Isomerized C 14  internal olefin and a mixture of isomerized C 15-20  internal olefins are converted to their epoxides by reacting with peracetic acid at 20‹ C. for 2 days, extracting the organic product, and thereafter fractionating. The epoxides are then reacted with dimethylamine to obtain the amino alcohol which is converted to the salt by neutralization with sulphuric acid. The preparation of the vicinal amino alcohol salt using 3,4-C 14  internal olefin and 5,6-C 15  internal olefin is also described. Alternatively the C 14  isomeric internal epoxide or mixture of isomerized C 15-20  internal epoxide are converted to the episulphide by reacting with thiourea, reacted with methyl sulphide in the presence of boron trifluoride etherate which produces after acidification the isomeric internal vicinal methyl sulphoxide and sulphonate. This method of preparation using 3,4-C 14  internal epoxide and 6,7-C 15  internal epoxide is also described. Alternatively the C 14  isomeric internal epoxide or mixture of isomerized C 15-20  internal epoxide are added to a solution of dimethyl phosphine and sodium in THF. After stirring glacial acetic acid is added thereby obtaining the phosphine acetate which is then reacted with hydrogen peroxide. The residue after removal of water was dissolved in methanolic KOH and refluxed thus producing the internal vicinal hydroxy phosphine oxide. The preparation of the vicinal hydroxy phosphine oxide using 5,6-C 14  internal epoxide and 5,6-C 16  internal epoxide is also described.
Patent GB-200262-A (GB)
Title: Improvements in the manufacture and application of vegetable, mineral and artificial tanning agents
IPC: C14C3/00
Filed: 1922-04-27
Abstract: The free acid in synthetic tanning agents containing sulphonic-acid groups is neutralized by means of ammonia or an organic base. Suitable organic bases are the amines and the amino-acids, which may be employed in an impure condition as occurring, for example, in the crude mixture of pyridine and quinoline bases obtained in the purification of coal tar, or in the mixture of amino-acids resulting from the hydrolysis of proteid material such as gelatin or hide or leather waste.  The tanning agent and the determined quantity of base required for neutralization are heated together at 80 DEG -100 DEG C., an excess of base being generally avoided.  The treatment may, however, be carried out under pressure, in which case a small excess of base may be employed which is afterwards neutralized by addition of a weak organic acid.  A modification of the process consists in effecting the hydrolysis of proteid material, with consequent production of the amino-acids required for neutralization, by means of the free acid present in the tanning-agent.  This hydrolysis may be effected with or without the application of pressure, and with or without catalysts, ferments, or enzymes. Examples are given describing the treatment of synthetic tanning agents of known type with aniline oil, crude pyridine bases, glycine, and with pyridine under pressure; the employment of synthetic tanning agents, with or without the application of pressure, to hydrolyse gelatin and leather shavings; and the production of a synthetic tanning agent by hydrolyzing glue with phenol, condensing the product with formaldehyde, sulphonating, and finally neutralizing with an organic base.  Reference has been directed by the Comptroller to Specifications 131,772, [Class 76, Leather], 157,855, and 175,362, [Class 76, Leather].

Title: New or improved alarm devices for automatic telephone systems
IPC: H04M11/04
Filed: 1927-05-05
Abstract: 295,242. Randall, W. J. May 5, 1927. Fire, police, and like alarm systems.-A pre-set impulse transmitter, controlled automatically by an alarm device, or manually, is adapted to connect a telephone, subscriber's station with a fire, police or other station and to transmit to that station a number or signal identifying the source of the alarm. One form of transmitter, shown in Fig. 10, comprises an impulse wheel A, cam C and worm-wheel G fixed on a shaft Y and driven by a spring D. The worm-wheel G meshes with a worm shaft WS connected to a centrifugal governor, and the wheel A carries detachable toothed and plain segments TS, PS. The transmitter is held in the set position by the engagement of a lever CR with the cam C, and is released by relay RY. The lever CR may be released manually or by a thermostat. To facilitate re-setting of the transmitter, the shaft WS is connected to the governor by a one-way clutch, and a slipping cam SC mounted on the shaft Y and normally held clear of the impulse springs IC against a fixed stop ST1, is carried around against a fixed stop ST2 by the wheel A during re-setting, to keep the springs IC closes. In order to give a longer pause before the commencement of impulsing than that provided by the first plain segment so as to ensure adequate time for the line switch to make connection to the first group selector, the cam C and wheel A rotate independently under the control of separate governors, the wheel A being held by a separate trip-lever. The cam C rotates at slower speed than the wheel A and when released by lever CR turns through a desired angle before it engages and releases the trip-lever of the wheel A. The cam and wheel complete their movements at approximately the same time. The Provisional Specification describes the use of separate transmitters for making the connection to the fire &c. station and sending the identifying signal.

Title: Improvements in hot-gas reciprocating engines and refrigerating engines operating onthe reversed hot-gas engine principle
IPC: F02G1/05
Filed: 1949-05-06
Abstract: 707.216. Refrigerating. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. May 6, 1949 [May 11, 1948], No. 12158/49. Class 29 [Also in Group XXVII] In a reciprocating refrigerating engine the amount of gas in the working space is varied by means of reservoirs 9, 10 under high and low pressure respectively, a valve 2 for connecting the reservoirs one at a time with the working space via a channel 15 being rotatable and slidable axially in a housing 1 and a helical channel 5 being provided in the valve adapted on axial movement of the valve to connect the reservoirs successively to the working space and a channel 6 being provided to vary the moment in the cycle when one of the reservoirs is cunnected with the working space. A hot gas engine is particularly. described. The valve 2 is rotated at the speed of the engine crank shaft by means of gears 17, 18 and slides axially in the gear 17. In the position of the valve shown the reservoir 9 is connected once during each revolution of the crank shaft to the channel 15, and the reservoir 9 communicates with the working space at the position of the crank shaft at which the working pressure is a minimum..The power thus supplied by the engine is a maximum. To reduce the power of the engine the valve 2 is moved downwardly so that the moment at which the reservoir communicates with the working space is changed thus giving a lower average pressure in the engine. When the valve has been displaced by the amount a, the reservoir 10 communicates with the working :space of the engine through a channel 8 and the channels 5, 6, and 15. Further displacement of the valve results in further reduction in power by changing the moment when the reservoir communicates with the working space. In order to maintain constant pressures in the reservoirs the reservoir 9 communicates by means of a reducing valve 11 with the reservoir 10 and the reservoir 10 communicates through a reducing valve 12 with a reservoir 13 which communicates with the reservoir 9 by a compressor 14. When an open regulating system is employed the space 13 may be dispensed with. A number of reservoirs of intermediate pressures may be arranged in series between the reservoirs 9, 13 each reservoir having a duct connecting it to the housing 1. Specification 697,082, [Group XXVII], is referred to.
