Abstract: 1,198,071. Prostaglandin analogues. G. E. JUST. 5 July, 1967 [9 Aug., 1966; 24 Jan., 1967], Nos. 35550/66 and 3588/67. Heading C2C. (R 1  is H, C 1-8  alkyl, C 3-10  cycloalkyl or C 7-10  aralkyl, or phenyl optionally substituted by 1 to 3 Cl atoms or C 1-4  alkyl groups; R 2  is H or C 1-8  alkyl; R 3  and R 4  are each H or C 1-4  alkyl; and C n H 2n  is C 1-8  alkylene). Compounds of the Formula VII and their salts, which are novel when they are racemates, or when they are optically active compounds excluding PGF 1 α and PGF 1 # and their salts and esters, are prepared by reducing compounds of the Formula VIII e.g. with sodium borohydride, to give compounds of the Formula XIII and converting these to the required products either directly using H 2 O 2  or a percarboxylic acid and a reactant acid which is (a) an organic acid with pK less than 4; or (b) a mixture of an organic acid with pK 4 to 6 and a catalytic amount of an acid with pK less than 2; or (c) an inorganic acid with pK less than 4; or (d) a Lewis acid; or (e) mixtures of these reactant acids, or indirectly via an epoxy compound of Formula XIV using the peroxidizing compound and the reactant acid sequentially. The reduction process gives isomeric hydroxy compounds which can be separated chromatographically. The opening of the cyclopropane ring gives products having both possible configurations for the OH in the unsaturated side chain. Any acylates of the ols formed in this process may be hydrolysed conventionally. Racemates or optically active compounds can be used in the processes, and when racemates are formed these may subsequently be resolved by known methods. Esters of the acid intermediates or final products may be conventionally hydrolysed. The prostaglandin F analogues of the Formula VII, which are stated to have the pharmacological activity, especially blood pressure lowering activity, of prostaglandins F 1 α and F 1 #, may be made up into pharmaceutical compositions with suitable carriers. Specifications 1,040,544 and 1,198,072 are referred to.

Title: Process for the production of aqueous polymer dispersions which are substantially free from residual monomer
Inventor: OEHMICHEN KLAUS
IPC: C08F20/62
Filed: 1969-01-23
Abstract: 1,245,498. Emulsion polymerization process. REICHHOLD - ALBERT - CHEMIE A.G. 23 Jan., 1969 [27 Jan., 1968], No. 3863/69. Heading C3P. An aqueous polymer dispersion substantially free from residual monomer is obtained by treating a dispersion of a homo- or co-polymer of acrylic or methacrylic acid or an ester thereof, prepared by emulsion polymerization in the presence of a conventional Redox catalyst system, until the free monomer content has fallen to a substantially constant level with a per-ester and/or per-ketal under conditions such that the per-ester or per-ketal activates polymerization of the residual monomer. The per-ester or perketal may be added to the reaction mixture prior to initiation of the reaction or during the polymerization and may be activated by raising the temperature of the reaction mixture or by adding a compound whichinduces decomposition of the per-ester or per-ketal, for instance a vanadyl or cobalt-II-salt, a tertiary amine or hydrazine, when the amount of free monomer has fallen to a constant level. Excess per-ester or per-ketal is destroyed by addition of a reducing agent after polymerization has been completed. In Examples 1 to 5, n-butyl acrylate, acrylic acid and styrene are copolymerized using a potassium persulphate/sodium metabisulphite catalyst, the residual monomers being polymerized by addition of tert-butyl perisononate, or peroctoate, or mono-tert. butyl permaleate, and vanadyl-p-toluene sulphonate, hydrazine also being added in Examples 2 and 4. The per-ester or per-ketal and vanadyl salt are added at earlier stages in Examples 6 to 16, the ester being one of the aforesaid esters, mono-tert. butyl peracetate or tert.-butyl perbenzoate. A mixture of tert. butyl perisononate and a per-ketal of formula or the per-ketal alone is also used and hydrazine hydrate is added in Examples 11 to 15. The procedure of Example 1 or Example 2 is repeated in Examples 17 to 23 for the production of poly(n-butyl acrylate), an ethyl acrylatestyrene-acrylic acid copolymer, a methyl acrylate-styrene-acrylic acid copolymer, a n-butyl acrylate-styrene-acrylic acid-acrylamide (or acrylonitrile) copolymer, a n-butyl acrylatemethacrylate-methacrylic acid copolymer and a n-butyl acrylate-styrene-methacrylic acid copolymer.

Title: Desalination of water by flash 'vaporation
IPC: C02F1/06
Filed: 1972-01-27
Abstract: 1377782 Flash-type evaporators; desalination of water SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 27 Jan 1972 3864/72 Heading B1B [Also in Division F4] Coolant comprising liquefied natural gas, liquefied methane or water, which coolant has been cooled by heat exchange with liquified natural gas or liquified methane, flows countercurrent to water passing through a flash evaporator/condensor for desalination. Water coolant may be water subsequently passed through the flash evaporator/condensor for desalination. Thus, water, such as sea water, is desalinated by heating it in coal 17 and then passing it through chambers 1 to 6 where flash evaporation takes place, the vapours being condensed on condensers 9 to 14 cooled by passing therethrough the feed water which has been previously cooled to just above freezing point by heat exchange with liquefied natural gas or liquefied methane. The feed water is passed through coil 28; and the liquefied gas is passed countercurrently through coil 26. The condensate, i.e. desalinated water, is collected in tray 30. The feed water is heated in coil 17 by passing low-pressure steam through the adjacent coil 23. In a modified apparatus (Fig. 2, not shown) liquefied gas is used as cooling-medium in the condensers.  In this case, the seawater need not be raised in temperature before evaporation, and the process can be operated so that the flashed steam initially condenses as ice on the condenser surfaces, but later condenses as water on the ice surfaces. Alternatively, the condensers may be arranged in parallel so that ice blocks may be released therefrom by passing warm gas through some of the condensers, while the others remain in service for condensing flashed steam as ice. The evaporator may be made of concrete.

Title: Improvements in or relating to telegraph transmitters
IPC: H04L17/06
Filed: 1955-02-09
Abstract: 766,961. Printing-telegraph transmitters. SIEMENS & HALSKE AKT.-GES. Feb. 9, 1955 [Feb. 9, 1954], No. 3929/55. Class 40 (3). In a telegraph transmitter in which levers selectively rocked by cams on a rotating shaft in dependence on the selective setting of corresponding selector elements temporarily displace from its normal position a common intermediate member provided with two surfaces operative to control the transmitting contact arrangement to a marking or spacing position by a control member actuated at predetermined times during the revolution of the rotating shaft, the operative surfaces of the intermediate member extend appreciably in the direction in which they are moved during the displacement of the intermediate member by the rocking of the said levers. A lever 3 is rocked clockwise when its projection 3a engages the low portion of its associated cam 2 and its end is not impeded by the upstanding portion of the associated selector bar 6 in its left-hand position. The movement of a lever 3 rocks the intermediate member 7 about a shaft 8 in a support 10 so that its projection 7b is in a position to be engaged by an extension 12b on a control member 12 arranged to be rocked by a star-shaped cam 15 immediately after a lever 3 has co-operated with the low portion of its associated cam 2. If the member 7 is not rocked, its projection 7a is in a position to be engaged by the extension 12a of the control member 12. The support 10 carrying the member 7 is secured to a shaft 11 on which is mounted a contact-operating member 16 having end surfaces comprising portions 16a, 16b of different curvatures connected by an inclined surface. The anticlockwise rotational movement of the member 16 by the member 7 closes contacts 17 and opens contacts 18. The shaft 11 carries a braking device comprising discs 20 held between spring-biased plates 21. For single-current working, one of the pairs of contacts 17, 18 may be dead. In a modification, Fig. 2 (not shown), spring-biased levers having separate extensions associated respectively with levers controlled by the selector bars and with the low portions of the cams operate a frame member with an arm engaging in the recess between the arms of a V- shaped intermediate member. The ends of the forked arms are associated with axial extensions of a contact-operating lever mounted on a shaft carrying a contact-operating arm which opens one or the other pair of two pairs of contacts. The V-shaped member is raised by a star-shaped cam immediately after a frame-operating lever has engaged the low portion of its associated cam.

Title: Improvements in or relating to time delay mechanisms
IPC: F16K31/48
Filed: 1958-02-06
Abstract: 856,167. Time switches. MIDGLEY, A. M. Feb. 2, 1959 [Feb. 6, 1958], No. 3946/58. Class 38 (5). [Also in Group XXIX] The supply of gas to an appliance e.g. a cooker, is regulated by main valve, not shown, under the control of a pilot valve comprising a spring-loaded ball-closure 4 with an actuating plunger 5 operable by a spring-loaded lever 9 that is slidable on and pivotable about a pin 10 under the influence of spindles 6, 7 of a timing apparatus 2 with an electrical or mechanical clock mechanism 3. The ball closure 4 is unseated by the lever 9 when the latter is in the normal position shown and the main valve is therefore open. Upon pushing and then rotating the starting spindle 6 the closure 4 remains unseated and the left end of the lever swings in a clockwise direction; when the spindle 7 is pressed and then rotated to set the stopping time it abuts the raised end of the lever 9. The timing apparatus now commences operation and upon the starting time being reached the spindle 6 is retracted and the lever 9 is urged clockwise by its spring away from the plunger 5 whereupon the closure 4 seats and enables the main valve to supply gas to the cooker. When the stopping time is reached the spindle 7 is retracted and the lever 9 returns to the position shown and so unseats the closure 4 thereby shutting-off the main valve. Upon removing the timing apparatus, e.g. for repair, the closure 4 seats and opens the main valve so that the gas supply to the cooker is under manual control. A further spindle 12 is provided which when pushed in, pivots the lever 9 so that the closure 4 is seated. The cooker may be electrically heated and the control switch is operated by a lever as described above. Spring contacts or plugs are used when an electric clock mechanism is used. In a further modification, the switch is made inoperative upon removal of the timing apparatus and manual means are provided for actuating the switch. Specification 768,842 is referred to.

Abstract: 440,387. Delivering measured quantities of granular and like fluent materials. HEIDE, Inc., H., 313, Hudson Street, Manhattan, New York, U.S.A.- (Assignees of Zwoyer, W. R. ; 103, Lenox Avenue, Maywood, New Jersey, U.S.A.) May 22, 1934, No. 4018/35. Convention date, Nov. 28, 1933. Divided out of 440,328. [Class 106 (v)] Apparatus for dispensing measured quantities of granular or like fluent materials comprises a hopper 209, a barrier 213 to control the passage of material from the main portion to an auxiliary portion of hopper so that the material is loosely scattered over only a part of the auxiliary portion, and a rotor having a number of depending cylindrical measuring chambers or tubes 203 each adapted to move over a discharge opening 24 just as it emerges from beneath the barrier and in its subsequent rotation, to be filled without pressure by the loosely scattered material before passing beneath the main portion of the hopper. By this means, jamming or clogging of the material within the measure due to the weight of the material in the hopper, is avoided. The form of apparatus shown has two measuring rotors M<1>, M<2> carried by shafts 202 journalled in a supporting platform 200 and rotated in opposite directions by gearing from a shaft 220 intermittently driven by pawl and ratchet mechanism. Extending diametrically over, but not entirely across, the top of each rotor is a barrier in the form of a brush 213 and a plate 214a. The discharge of each measuring chamber when over the opening 24 is facilitated by one or more blows from strikers 240 of wood or other material, adapted to be moved against the action of a spring and then released by engagement with the preceding measuring chamber. A series of blows may be obtained by using a number of strikers of different lengths.
