Title: Process for the production of salts of poly-a-hydroxyacrylic acids
IPC: C07C51/377
Filed: 1975-04-29
Abstract: 1450758 Salts of poly(alpha-hydroxyacrylic acids) SOLVAY & CIE 29 April 1975 [30 April 1974] 17762/75 Heading C3P Polymer salts containing units of formula wherein R 1  and R 2  each represent a hydrogen atom or a C 1-3  alkyl group and M is a cation, are prepared by reacting a base with a solid polylactone derived from the corresponding polyalpha - hydroxycarboxylic acid, the reaction being effected in the presence of a liquid medium, comprising water and a diluent, which dissolves neither the polylactone nor the salt being produced. The liquid medium preferably contains 10-60% water, and the diluent is suitably a C 1-5  alcohol. The base, which provides the cation M, may be either organic or inorganic. In Examples, the polylactone of poly-alphahydroxy acrylic acid is reacted with sodium hydroxide in a liquid medium comprising water and either methanol or ethanol.
Patent GB-669074-A (GB)
Title: Process for the production of unsaturated phenolic compounds
IPC: C07C37/00
Filed: 1949-07-06
Abstract: Phenols and their ethers having at least one nuclear aliphatic hydrocarbon substituent of 3-28 carbon atoms, the two carbon atoms nearest the aromatic nucleus each bearing at least one hydrogen atom, are cracked in the vapour phase at an elevated temperature to convert the substituent into one with an a  : b -double bond.  A dehydrogenation catalyst of the kind used for dehydrogenating ethylbenzene (e.g. as in Specification 340,587, [Group III]) is preferably used, the reaction taking place at 400-800 DEG  C.; a gaseous diluent such as steam, hydrogen, benzene, nitrogen or carbon dioxide may be present.  The pressure may be atmospheric or higher or lower.  When no catalyst is used, a solid heat-transfer material is preferably present.  The preferred temperature range is 500-700 DEG C. with a contact time of 1-0.01 seconds.  Depolymerization and replacement of nuclear carboxyl by hydrogen may occur simultaneously with the cracking, depending on the starting material used.  The products may be separated by distillation or fractionation, followed by alkali extraction and selective precipitation with carbon dioxide or a stronger acid.  A further fractionation may be carried out as the final step.  In the examples: (1) cardanol from cashew nut shell liquid gives m-vinylphenol and non-phenolic bodies; (2) cardanol gives phenol, m-cresol, m-ethylphenol, m-vinylphenol and a higher-boiling residue; (3) cardanyl methyl ether gives m-methoxystyrene, m-vinylphenol and hydrocarbons; (4) p-n-hexylphenol gives p-vinylphenol and hydrocarbons.  The process is applicable to alkyl-phenols and their alkyl and aryl ethers, such as those in coal tar and the components or distillates of cashew nut shell liquid including their hydrogenated derivatives.  When a phenolic acid such as anacardic acid is used, decarboxylation takes place and the carbon dioxide evolved may function as the whole or part of the inert diluent.ALSO:Dehydrogenation catalysts comprise: (1) granular absorbent alumina on which is deposited 10 per cent by weight of calcium oxide; and (2) granular magnesite carrying 5.3 per cent of sodium vanadate.  They are used for the cracking of alkyl-substituted phenols and their ethers to give alkenyl-substituted compounds with fewer carbon atoms.

Title: Improvements relating to ceramic bodies in particular for use as insulators for spark plugs
IPC: H01T13/38
Filed: 1936-06-27
Abstract: A quartz-free ceramic body suitable for sparking-plug insulators is made by sintering into a dense, non-porous mass, at a temperature of the order of Seger cone 30 to 35 an intimate mixture of finely ground material containing the equivalent of 85-99 per cent of alumina and 15-1 per cent of silica.  The sintered body contains from 46-96 per cent of corundum and from 3 to 53 per cent of mullite with very little glass, preferably not more than 2 per cent.  In making sparking-plug insulators, the raw mixture may be moulded under heavy pressure, e.g. by the method described in Specification 472,110.  The preferred method is that described in Specification 472,110 in which a thermoplastic synthetic resin is added to the raw materials and the insulator shapes are formed under heat and heavy pressure before being fired.  In an example, a raw body comprises 40 parts of calcined cyanite and 60 parts of calcined alumina.  Flux up to 10 per cent may be added.  The resulting product consists of substantially 50 per cent of corundum and 50 per cent of mullite.  Another raw mixture comprises 90 parts of alumina, 5 parts of cyanite and 5 parts of talc as flux.

Title: Improvements in measuring apparatus employing ultrasonic waves
Inventor: RANKIN ALEXANDER BRYCE CALDER
IPC: G01N29/24
Filed: 1953-06-30
Abstract: 770,398. Testing materials by ultrasonic vibrations. KELVIN & HUGHES, Ltd. May 31, 1954 [June 30, 1953], No. 18144/53. Class 118 (2). Measuring apparatus (particularly for the assessment of grain size in anisotropic polycrystalline materials such as metallurgical specimens) comprises a source of electric oscillations of ultrasonic frequency and transmitting and receiving transducers adapted to generate ultrasonic waves from the said oscillations and to pass said waves into, and receive the waves after propagation through, two wave-transmitting bodies (whose grain size is to be compared), the receiving transducer or transducers being coupled to a voltage-indicating device and the arrangement being such that when the two bodies are like substantially zero voltage is applied to the indicating device. The source 15 (Fig. 1), may energize two piezoelectric crystals 10, 12, and receiving crystals 11, 13 are connected to an indicator 17. One receiving or transmitting crystal is reversed relative to the other. A standard specimen is arranged between crystals 10 and 11 a specimen to be tested (of like dimensions) is arranged between crystals 12 and 13. The crystals are coupled to the respective end faces of the specimens by a suitable couplant such as a thin film of wax or oil. A number of standard specimens of different grain sizes may be provided and the one showing the lowest reading on indicator 17 gives the grain size of the specimen under test. If it is desired to know whether the grain size of the test specimen is smaller or larger than that of the standard in use the phase of the detected signal may be determined by using a cathode-ray tube presentation or a phase discriminating circuit in conjunction with a valve voltmeter. The crystals may be mounted on wedges to form probes (Fig. 4, not shown) suitable for Rayleigh, shear or longitudinal waves according to the angle of the wedge. The probes may be mechanically coupled together in pairs (Fig. 3, not shown), to fix the spacing between transmitter and receiver. Fig. 2 shows a modification for testing material in the form of prepared specimens 22 and 23, one being a standard and the other of material under test, wherein only three crystals, 18, 19 and 20 are used. The crystal 19 forms a common transmitter and crystals 18 and 20 are connected in opposition. The whole arrangement is immersed in a suitable liquid such as paraffin oil in a vessel 21, and the specimens 22, 23 fit close to but out of contact with the crystals. A constructional embodiment of the arrangement shown schematically in Fig. 2 is described and illustrated in Fig. 5 (not shown). Specification 770,397 is referred to.

Filed: 1933-06-26
Abstract: 408,473. Aerials. KOOMANS, N., 133, Willem de Zwijgerlaan, The Hague. June 26, 1933, No. 18169. Convention date, June 24, 1932. [Class 40 (v).] A unidirectional aerial comprises a series of half or quarter wave doublets a connected directly to a supply conductor d, d at apacings of half a wavelength, and a second series of parallel doublets b fed from a conductor e, e being interposed between the first series. The conductors d, e are strung through crossinsulators f and are given a non-inductive twist as shown. Owing to the quarter-wave spacing between a and b, a phase-difference of 90‹ exists, and a further phase difference of 90‹ is introduced between the currents supplied to the conductors d, e. One set of doublets may therefore be considered as a radiating system, and the other as a reflecting system. The main direction of radiation can then be reversed by a simple switching over of the supply.

Title: Improvements in or relating to automatic shuttle-changing mechanism for looms
IPC: D03D45/34
Filed: 1932-06-28
Abstract: 403,135. Looms with'automatic weftreplenishing mechanism. AUERBACH, M., 138, Javastraat, The Hague. June 28, 1932, No. 18214. [Classes 142 (i) and 142 (iii).] Shuttle-changing mechanism.-The pivoted front and rear walls of a shuttle-box are simultaneously opened by a detent controlled from the change shaft engaging a movable member on the advancing lay, the detent being restored to normal position and the shuttle box walls closed after replenishment through the agency of a second detent or a curved guide on the lay when the latter reaches its extreme forward position. In the construction shown in Fig. 2, the shuttle box walls 28, 34 are connected to a bell crank lever 24 one arm of which abuts a slidable lay member 16 that can be displaced longitudinally by a pivoted lever 13 when the latter is released, by rocking of the change shaft 10 on weft exhaustion, and rocked by a spring 15. The rocking of the lever 13 is utilised to position a trigger in the path of a striker button on the lay and as the latter advances a transferrer 22 is operated to push a fresh shuttle into the box. At the end of the forward stroke of the lay an abutment 38 thereon rocks a knee lever 36-37 to reposition the lever 13 and allow the shuttle-box walls to be lowered under the action of a spring 40. Alternatively the lever 13 may be pivoted to swing in the plane of movement of the lay so as to act directly on the bell crank lever 24 in which case it is reset at the end of the forward stroke by a tapered projection thereon engaging a lay abutment. In a modification the box walls are opened by the engagement of a curved member 75, Fig. 10, with a pivoted lever 71 which is normally retained in inoperative position by a catch 64 having a Bowden wire connection with the change shaft 67, a stop piece 62 being provided to limit its forward movement. As the member 75 moves clear of the lever 71 an impulse is imparted to the latter to return it to a position in which it can be engaged by the catch 64 and the box walls are closed by the action of a spring. In a further modification withdrawal of a pivoted catch releases a weighted lever and permits a box opening detent, connected therewith, to move into the path of a lever associated with the shuttle box walls. Stop-motion acting on obstruction of weftreplenishing mechanism. A two armed lever 42, Fig. 6, pivoted on a lever 44 mounted on the usual stop rod, is formed with a head 47 to engage a projection 34a on the rear wall of the shuttle box and an arm 46 that can be engaged by stop 48 on the rearward stroke o f the lay. If a jammed or improperly positioned shuttle prevents return of the rear wall after replenishment, the stop 48 rocks the lever 42 from dotted to full line position and moves a tongue 49 into the path of a frog 50 to effect stoppage.

Class 107 A road or like surface is laid by an adjustable guide platform being intermittently moved forward without the use of guide rails, and having a surface-laying device moved forward relatively to the platform during its immobile periods. The platform is adjustable for both height and direction. The roadway may be produced in a single operating cycle or bermes may first be produced and thereafter the spaces left between them can be filled. Bench marks are first determined and then bermes 1 are laid by the machine which may have two spaced guide platforms each having a surface-laying device associated therewith. The machine, Fig. 3, is driven by a tractor 5 and consists of two guide platforms 6 (only one shown) interconnected by a cross member 7. The surface-laying device 11 is carried on side members 9 by rollers 12. A belt 15 drives the mechanism of the device 11. The surface-laying device is stationary whilst the guide platform is moved, and then, when the latter is immobile, it is moved forwardty of the platform to lay two lengths of berme. The surface-laying device 11 has a hopper 12a (see Fig. 6) vibrated by an out of balance rotatable weight 25 driven via a belt from the belt 15. A horizontal ram 23 is also driven from the belt 15 through reducing gearing and connecting rods 24. The counter thrust to the ram feeds the device 11 forward and a braking arrangement 27a allows the effective thrust of the ram to be varied by varying the friction of the device 11 on the rails..
