Title: Process of manufacturing fertilisers
IPC: C05B7/00
Filed: 1931-01-16
Abstract: A method of carrying out the process of the parent Specification is characterized by acidifying for instance with sulphuric acid, but preferably with phosphoric or hydrochloric acid, the mother liquor resulting from the separation of microcosmic salt prior to the crystallization of the mixture of potassium and ammonium chlorides (potazote).  By this means, potazote is obtained free from phosphoric acid.  In carrying out the process cyclically, phosphoric acid and ammonia, replaced in part, if desired, by mono-, di-, or triammonium phosphate, are added to the mother liquor from the separation of potazote until it contains one molecule of phosphoric acid to two molecules of ammonia, and the solution cooled to allow of separation of microcosmic salt.  Sylvinite and phosphoric acid, the amount of the latter being about 15 per cent of the acid used in the process, are added to the mother liquor, and potazote is then separated from the cooled solution.  The products are employed as fertilizers.ALSO:A method of carrying out the process of the parent Specification is characterized by acidifying for instance with sulphuric acid, but preferably with phosphoric or hydrochloric acid, the mother liquor resulting from the separation of microcosmic salt prior to the crystallization of the mixture of potassium and ammonium chlorides (potazote).

Title: Improvements in or relating to methods of and means for amplifying the light intensity of an optically projected image
IPC: G02B27/54
Filed: 1956-01-18
Abstract: 808,981. Photo-conductor devices. GESELLSCHAFT ZUR FORDERUNG DER FORSCHUNG AN DER EIDGENOSSISCHEN TECHNISCHEN HOCHSCHULE. Jan. 18, 1956 [Jan. 18 1955], No. 1724/56. Class 37. [Also in Groups XX and XL (b)] In an arrangement for amplifying the light intensity of an optically projected image by the use of a control multi-layer device in a schlieren optical system to modulate the light from a separate light source, the control layer includes the combination of a light-sensitive layer with a layer of a substance exhibiting the electrical Kerr effect and a mirror layer of electrically insulating material. In the arrangement shown, a glass plate 1 carries a thin transparent metal (platinum) electrode 2 and a lightsensitive layer 3 of, for example, selenium in conjunction with copper-activated zinc sulphide. On this layer is a thin light-absorbing and electrically-insulating layer 4 carrying a mirror layer 5, the layer 4 being omitted if the mirror layer has very poor transparency. The mirror layer is formed by a stack of quarter wavelength dielectric films of alternate high and low refractive index. The layer 6 is of the substance exhibiting the Kerr effect and may be nitrobenzene, a colloidal solution of, for example, vanadium pentoxide, or a solid body composed of mono-calcium phosphate or mono-ammonium phosphate. A second electrode 2a is carried by a glass plate 1a, and a polarizing A.C. or D.C. voltage is applied to the electrodes 2, 2a. The light P incident on the light-sensitive element 3 causes the field produced by the polarizing voltage to be varied so that the refractive index of the layer 6 is changed and light, from the source 10, reflected by a mirror 11 and normally reflected back from the mirror layer 5 to the bars of the system 17 is refracted and passes via a lens 16 through the slits of the system to a mirror 12 and to the screen 14. The control multi-layer may be spherically concave to the light to be reflected, Fig. 3 (not shown), and the lens 16 is preferably omitted in this arrangement. For picture reproduction the image projected in the direction P on the light-sensitive layer 3 must be rastered, and for this purpose a finely meshed grid is introduced at a convenient point, for example at the surface of the carrier 1 or adjacent the film or other subject to be projected on the multi-layer element. Specifications 543,485 and 561,926, [both in Group XL], are referred to.
Patent GB-358831-A (GB)
IPC: C07C53/08
Filed: 1931-01-19
Abstract: Liquid mixtures of acetic anhydride, acetic acid and water are cooled to cause the separation of the water.  If the cooling is rapid and vigorous, all the water and most of the acetic acid separate out, but by cooling in stages first pure or strong acetic acid and then acetic acid with the rest of the water separate leaving a liquid portion consisting of acetic anhydride with the rest of the acetic acid.  The solubility of water in the mixture may be reduced by adding hydrocarbons such as benzene or toluene or other liquids such as methylene chloride, carbon disulphide, sulphur dioxide, or a mixture of sulphur dioxide with carbon dioxide.  If these additions, which also dissolve acetic acid, are added in considerable amount, the water separates out alone; by using liquids which are also cooling agents, such as sulphur dioxide, other means of cooling can be dispensed with.  In examples (1) the mixture is cooled to -30 DEG C., strong acetic acid separating; the filtrate is then cooled to -40 DEG  C. when a weaker acetic acid separates, leaving acetic anhydride containing some acetic acid; (2) the same mixture is cooled to -40 DEG  C., all the water separating with most of the acetic acid; (3) the same mixture is treated with methylene chloride, the resulting temperature being -50 DEG  C., the crystals containing all the water and some acetic acid being washed with methylene chloride; (4) the same mixture is mixed with liquid sulphur dioxide, at -70 DEG  C., all the water separating out alone; by evaporating the sulphur dioxide from the filtrate, most of the acetic acid separates out; (5) a mixture of liquid sulphur dioxide and carbon dioxide is used instead of liquid sulphur dioxide, with similar results.

Title: Improvements in or relating to watchmen's control systems
IPC: G08B21/00
Filed: 1948-01-21
Abstract: 648,458. Exchange systems. SHIPTON, E. Jan. 21, 1948, No. 1799. [Class 40 (iv)] [Also in Group XIXJ A watchman's control system comprises alarm apparatus controlled by switch means having two parts, one being operated automatically at predetermined time intervals and thesecond being operated by the watchman completing the actuation of all the control devices on his beat, the alarm being given if the second part of the switch means is not maintained in step with the automatically operated part. At predetermined times a clock-actuated switch closes to byepass an alarm device for a period sufficient to allow a watchman to operate a series of switches on his beat which, if correctly operated, close another byepass until it is time for the cycle to be repeated. In one embodiment, a circuit diagram for which is shown, current to a relay B controlling an alarm device is normally byepassed through a pair of contacts p, q belonging to rotary switches S1, S2 whose contacts are interlinked in pairs, but once an hour a clockactuated switch PSC closes to excite a relay A and advance the wiper arm of switch S1 to break the first byepass circuit whilst immediately before another clock-actuated switch AGT closes for 15 minutes to byepass the alarm relay B. The watchman is then scheduled to close contacts K1, K2 ... in correct sequence to advance a wiper arm of rotary switch S3 step by step till a wiper arm moving over a second bank of contacts finally closes a circuit to advance the wiper arm of switch S2 to complete the byepass circuit through the second pair of contacts p, q, meanwhile the first wiper arm has closed a contact to return the wipers to the first position. Should the watchman fail to operate all the switches in correct order within fifteen minutes the switch AGT will open and since the arms of switches S1, S2 will still be out of phase the relay B will be excited and through contact b3 will light a warning lamp L and through contact b1 complete a circuit through a thermal time delay switch TD which in due course will close a switch TDS to actuate the alarm W unless the error has been rectified and switch S2 brought into phase with switch S1. At its contact b4 relay B closes a locking circuit so that the alarm will continue irrespective of the later closing of the clockactuated switch AGT. Specifications 394,021, 467,204 and 640,290 are referred to.

Title: Improvements in or relating to hypodermic syringes
IPC: A61M5/24
Filed: 1936-01-21
Abstract: 457,152. Hypodermic syringes. COOK LABORATORIES, Inc., 170, Varick Street, New York, U.S.A.-(Assignees of Montuori, F. C. ; Medical Science Building, Washington, U.S.A.) Jan. 21, 1936, No. 1947. Convention date, Nov. 14, 1935. [Class 81 (ii)] A hypodermic syringe comprises a tubular body having a longitudinal aperture for the insertion of a cartridge, a retaining member adapted to engage with and hold the cartridge in position and resilient means, anchored within the body, which engage with the cartridge when this is inserted into the body and constantly urge it outwards thereby automatically ejecting the cartridge when the retaining means is rendered inoperative. As shown, the hollow barrel 1 of the syringe is provided with a longitudinal aperture 11 through which a cartridge 2 is inserted. The cartridge retaining member consists of a slidable hollow collar 8 which is held in its operative position by a 'coiled spring 9. An outward movement of the plunger rod 7 compresss the spring 9 and frees the cartridge from the locking action of the collar 8 whereupon a leaf spring 16 forces the cartridge 2 out of the barrel. At the same time a leaf spring 15, the end of which lies in a guideway 17 provided in the collar 8 (See Fig. 4), operates to arrest the action of the spring 9 on the collar 8 by resting against a bridge 20. The insertion of a cartridge compresses the left springs and the locking action of the collar 8 comes into operation through the expansion of the spring 9. An inward movement of the plunger-rod 7 then pushes a slidable plug 14 in the cartridge thus ejecting medicament through a needle 4. The barrel of the syringe is provided with an indentation in alignment with the spring 15 which brings the guideway 17 into alignment with the spring. U.S.A. Specification 1,757,809 is referred to.
