Title: A process for the extraction of alkaloids from poppy straw and/or capsules
IPC: C07G5/00
Filed: 1952-02-08
Abstract: Morphine is extracted from poppies by mixing dry, finely ground poppy straw and/or capsules with lime and enough water to wet the mass, pressing out the extract, adding sulphuric acid to pH 4-5.5, evaporating under reduced pressure until the mass is firm when cold but fluid when hot, making alkaline (other than with caustic alkali) and extracting the alkaloids with a water-immiscible solvent, preferably at an elevated temperature. When making the mixture alkaline, caustic alkali may be used to bring the pH to 6-7 and another alkali then added for the final step.  In preferred operating conditions the straw and/or capsules are mixed with 5 per cent of calcium hydroxide and 4 times their weight of water and allowed to stand for 2 hours.  The extract is pressed out, acidified to pH 4.5-5.5, evaporated under reduced pressure, made alkaline with sodium carbonate and the morphine extracted with a mixture of fusel oil and xylene at 100 DEG  C.  The morphine is recovered by extraction with hydrochloric acid and precipitation with ammonia.  An example is given of the process.

Title: Improvements in apparatus for the construction of concrete roads
IPC: E01C19/40
Filed: 1941-03-19
Abstract: 546,193. Concrete spreading machines. BLAW KNOX, Ltd. March 19, 1941, No. 3778. Convention date, March 19, 1940. [Class 107] In an apparatus for spreading concrete in laying roads &c. a scraper or spreader moving transversely between form rails arranged at each side of the lane moves the surplus concrete transversely and forwardly, and a screed behind the scraper levels the concrete in a forward direction. The machine is mounted on wheels 3, 4, Fig. 1, to run along the rails or forms at each side of the lane to be paved. The frame of the machine carries a vibrating box-like screed 17, and immediately ahead of the screed a trolley 7 carries a spreader 56 for spreading and maintaining a constant height of concrete in front of the screed. The trolley is moved to-and-fro across the machine by means of a pin 60 projecting from an endless chain 44 driven by an engine 27. The spreader is secured to the lower end of a vertical spindle 55 adjustable axially to regulate the height of the scraped concrete in front or the screed. At each end of its transverse movement the spreader is rotated by a stationary abutment 66a or 66b into a reversely inclined position at the opposite side of the pile of concrete and is temporarily latched during the return movement. In a modification, Fig. 12, the trolley 75 is traversed by a chain 86 driven to- and-fro by a driving sprocket 87. The chain passes over a sprocket 85 geared to a twopronged spreader 78 abutting against one of two stops 88. At each end of a transverse movement, the reversing movement of the driving chain 86 rotates the sprocket 85 and brings the other prong of the spreader into action. The height of the spreader is adjusted by raising or lowering the trolley runway 76 by means of a crank handle 76a. In a further modification, Fig. 15 (not shown), the trolley carries two parallel spreaders which are alternately moved in a vertical direction into and out of action at the end of each transverse movement of the trolley. Specification 439,223 is referred to.

Patent GB-902364-A (GB)
Title: Process for dyeing or printing textile materials
IPC: C09B62/523
Filed: 1961-02-01
Abstract: Textile materials, especially those of cellulose, are dyed or printed with a vat dyestuff containing at least one sulphonic acid amide group the nitrogen atom of which is bound to an aliphatic chain, which chain may be interrupted by a hetero atom, which chain contains a sulphuric acid semi-ester group, and which chain contains at least three carbon atoms between the nitrogen atom and the sulphuric acid ester group, the dyestuff being reduced to the leuco form before or during the dyeing or printing process and the leuco compound being oxidised on the fibre.  The sulphuric acid semi-ester residue, which imparts water-solubility to the dyestuff, readily splits off under the normal conditions employed for dyeing or printing with vat dyestuffs.  Dyeing may be effected by the exhaustion method at 20 DEG -90 DEG C. from a bath containing the dyestuff, an alkali, such as an alkali metal hydroxide, and a reducing agent, such as sodium hydrosulphite, thiourea dioxide, sodium sulphide, sodium hydrosulphide, glucose or hydrazine, or by padding with a dyestuff solution followed by impregnation with a solution of an alkali and a reducing agent. In the case of printing at a low temperature or with subsequent steaming for a short time, an after-treatment with an alkali metal hydroxide, preferably in the soap bath, is applied. Dyestuffs of the anthraquinone, perylene, perinone, pyrene-quinone, indigoid or phthalocyanine series may be employed and are prepared by reacting a sulphochloride of the dyestuff with an alkanolamine and reacting the oxyalkyl-sulphonamide so-obtained with concentrated sulphuric acid or chlorosulphonic acid.  Examples of dyeing and printing are given and numerous dyestuffs are listed therein.  In Example 2 the dyestuff of the following formula is employed:- <FORM:0902364/IV (b)/1>

IPC: G01S1/24
Filed: 1952-02-13
Abstract: 813,170. Automatic phase-control systems. MARTIN CO., G. L. Feb. 13, 1952, No. 3893/52. Drawings to Specification. Class 38 (4). [Also in Group XL (c)] In a hyperbolic navigation system, the slave station emits a microwave pulse at a predetermined time after the pulse from the master station and the slave receives a synchronizing signal from the master through a relay transmitter-receiver carried in an aircraft flying above the master. In order that the timespacing between the master and slave pulses is maintained constant and independent of the position of the relay aircraft, the time spacing of the synchronizing signal with respect to the master pulse is adjusted automatically in correspondence with the length of the path traversed by the synchronizing signal and therefore varies with the aircraft position. Continuouswave transmission may be employed and provision is made for the continuance of the system should the synchronizing signals fail to be received by the slave. The synchronizing signal from the master passes to the relay, in the aircraft, from the relay to the slave and is returned over the same path to the master where its time spacing is compared with that of a reference pulse. A difference in the time spacing of the reference and the returned synchronizing signal generates an error signal which adjusts the time of transmission of the synchronizing signal to ensure that it arrives at the slave at the predetermined time. At the slave, a stable oscillator is normally maintained in synchronism with the master oscillator by the synchronizing signals and should the latter fail, transmission from the slave will not be interrupted.
