Title: Alpha-phenoxy-alkonic acids and derivatives thereof
IPC: A61K31/22
Filed: 1971-06-17
Abstract: 1353362 α-Phenoxyacetic acids CIBAGEIGY AG 17 June 1971 [10 Dec 1970 5 Feb 1971 7 May 1971] 28455/71 Addition to 1332824 Heading C2C Novel α-phenoxyacetic acids in which the α-position is substituted by an alkyl residue having 5 to 12 carbon atoms and the phenyl residue is substituted by a singly unsaturated cycloalkenyl residue the double bond of which extend from the carbon atom adjacent to the phenyl residue to an adjacent carbon atom, or an ester or amide thereof may be prepared by condensation of a phenol that is substituted by a singly unsaturated cycloalkenyl residue the double bond of which extend from the carbon atom adjacent to the phenyl residue to an adjacent carbon atom, with an ester of a glycolic acid that is reactively esterified at the alcoholic hydroxyl group and is substituted in the α- position by a C 5-12  alkyl residue and, if desired, forming a free acid, an amide or a salt thereof or resolving isomers.  The intermediates p-(1-cyclohexenyl) and (1- cyclo-octenyl)-phenol may be prepared by forming a Grignard reagent with p-bromo anisole, reacting it with cyclohexanone or cyclo-octanone, followed by dehydration of p-(1-hydroxycyclohexyl) anisole to p-(1-cyclohexenyl)-anisole (p-(1-cyclo-octenyl)-anisole is formed directly as the product of the Grignard reaction), followed by demethylation to form the free phenol. Pharmaceutical compositions of the α-phenoxyacetic acids have a serum-lipid-lowering action when administered orally, parenterally or rectally with the usual excipients.

Title: Improvements relating to ammunition projectile fuzes
IPC: F42C15/285
Filed: 1948-11-02
Abstract: 653,547. Ammunition projectile fuzes. VERWALTUNGSGES DER WERK-ZENGMASCHINENFABRIK OERLIKON. Nov. 2, 1948, No. 28472. Convention date, Nov. 3, 1947. [Class 9 (i)] The striker 12 is normally prevented from igniting the primer 14 by a transversely slidable body 6 which is forced to one side of an accommodating recess in the fuze body by a spring 15 but which, during flight, is moved to an armed position after the escape therefrom of a heavy, liquid material 8. Such escape of the liquid material, which may be mercury, displaces the centre of gravity of the body in such manner that it moves by centrifugal force to the armed position against the action of the spring 15. In the construction shown the recess accommodating the mercury has an aperture 9 normally closed by a diaphragm 10 ; in flight the mercury pierces the diaphragm and enters an annular cavity in the fuze body. The striker is normally prevented from moving towards the primer by a shoulder 13 protruding into a slot 11, but is free to pass through the slot when the shoulder moves out of its path. A further recess in the body contains a lead filling 7, but in a modification this is dispensed with.

Abstract: 1,007,366. Unloading bulk granular material from vehicles. ATKINSONS OF CLITHEROE Ltd. July 8, 1964 [July 19, 1963], No. 28642/63. Heading B8E. [Also in Division G1] Granular material is moved to the rear of a vehicle 10, Fig. 1, by an endless belt conveyer where it is either bagged and weighed by a device 13, fed on to an endless conveyer 20, Fig. 4, or fed to a pneumatic conveyer 29. The conveyer in the floor of the vehicle is hydraulically driven either by the vehicle's engine or a subsidiary engine. Bags 14, Fig. 1, are suspended from a cradle 15 which is raised and lowered by hydraulically operated arms 18. An interlock ensures that the bags are not raised until they contain a certain minimum amount of material. The lifting means incorporates a bag counter, preferably electrical. The conveyer 20, Fig. 4, is normally stowed on the vehicle and is pivotably supported in use by a cable 21 and arms 22, 24. An electrically driven winch 26 raises and lowers the conveyer. The latter is hydraulically driven and may be slewed through 180 degrees. For pneumatic delivery pipes may be coupled to one or both sides of a reversible rotary seal 29.

Filed: 1946-09-30
Abstract: 622,838. Valve generating circuits; valve superheterodyne circuits. PHILIPS LAMPS, Ltd. Sept. 30, 1946, No. 29124. Convention date, May 25, 1943. [Classes 40 (v) and 40 (vi)] Tunable apparatus such as a radio transmitter or receiver has its frequency determined by the sum or difference of two frequencies, one of which is tunable in steps and the other continuously over a number of at least two different frequency bands having the same width, the frequency being selected so that interference due to higher harmonics is substantially avoided. Fig. 1 shows the application to a superheterodyne receiver. Signals in the range 1.5-22.5 Mc/s. are applied to the H.F. stages 2 and to the mixer stage 3. The local oscillator 8 which is preferably crystal controlled is adjustable in 1 Mc/s. steps from 0-19 Mc/s., oscillator 9 is adjustable in a continuous manner over the frequency bands 2-3, 3-4, 4-5, 5-6 Mc/s. The two local oscillators are mixed in stage 10 to give the sum of their individual frequencies and the resultant passed through the band-pass filter 11 which is adjusted with the tuning of oscillators 8, 9. The resultant oscillation is mixed in stage 3 with the incoming signals to give an I.F. of 500 kc/s. Data is given showing how interference due to harmonics may be reduced. The tuning adjustment is preferably associated with a switch to ensure the correct combination for any given tuning frequency. In a modification, Fig. 2, three local oscillators are used. Oscillator 13 is continuously variable over the range 2-3 Mc/s and is mixed with oscillator 12 which has a frequency of either 20 or 22 Mc/s., the sum frequencies appearing at the output are mixed with oscillator 8 which can be switched in 1 Mc/s. steps from 0-20 Mc/s. The difference of these two frequencies is produced in mixer stage 10, the continuously variable frequency 22-23 or 24-25 Mc/s. exceeding the frequency of that of the resultant beating oscillator except for the one range 22-23 Mc/s., where the two are equal.

Title: Improvements in or relating to extruded protein products
Inventor: BATCHELOR-WILLIAMS EIFION OWEN
IPC: C08L89/00
Filed: 1955-10-13
Abstract: Extruded and hardened protein products, e.g. films or tubes, are heated in a water-immiscible organic liquid for a time and at a temperature sufficient to impart transparency thereto, and are then subjected to aqueous treatment.  The protein product may be prepared from a vegetable globulin, such as groundnut or soya protein, or from an animal protein, such as casein, and the water-immiscible organic liquid may be a mineral or vegetable oil, fat, or wax, e.g. groundnut oil, or an organic solvent boiling at not less than 115 DEG  C., such as xylene or a petroleum fraction. The heat-treatment may be carried out either at atmospheric pressure at a temperature not less than 115 DEG  C., or at reduced pressure at a lower temperature, e.g. 100 DEG C.  The treatment may be by immersion of the product in an electrolyte solution, and this may be followed by glycerine immersion.  Initial hardening of the product may be by immersion in hot aqueous formaldehyde containing a salt, preferred conditions for hardening sausage casings being 3 per cent formaldehyde/22 per cent sodium sulphate solution at 80 DEG  C.
