Preferred compounds are obtained by ring closure, in the presence of a strongly acidic reagent, of a substituted 2-benzyl-4-piperidinol of the Forumla (III) in which R 2  is an alkyl, aryl, heteroaryl, or aralkyl group, R<SP>11</SP> 1  is an alkyl or aralkyl group and R<SP>1</SP> 3  is H, OH or alkoxy. Replacement of substitutents already present and/or introduction of further substituents may be effected by esterification or etherification of compounds having an OH in the 2<SP>1</SP> position, and/or by removal of R<SP>11</SP> 1 , when methyl, by the von Braun reaction or, when benzyl, by catalytic hydrogenolysis, followed by reaction with a carboxylic halide followed by reduction of the amide obtained with a complex metal hydride or by direct alkylation. The products may also be resolved in to optical enantiomers by reaction with an optically active acid and/or converted in to therapeutically acceptable salts. Pharmaceutical compositions having analgesic and/or morphine antagonistic activity comprise a compound of Forumla I above together with an inert physiologically acceptable carrier.

A crimped conjugate staple fibre having an improved spinnability, wherein at least two different synthetic polymers are bonded in an eccentric relation to each other along the fibre axis, is chatacterized in that the length (L), free length (F), number of crimps (N 0 ) and fineness (d) of said fibres satisfy simultaneously all of the following four formulµ:- The ratio F/L is the free length ratio, where F is the maximum length of one of the staple fibres when it is mounted on a smooth plane under no tension and no mutual restriction between the fibres, and L is the fibre length when a load of 1 mg./denier is applied; N 0  is the number of pitches/25 mm. of staple fibre. The staple fibres are made by feeding a tow composed of crimpable conjugate filaments into a liquid at a temperature of at least 70‹ C., e.g. boiling water or glycerine at 70‹ to 100‹ C., at a constant rate to develop crimps latent in the filament, removing the crimped tow at a lower rate than the feeding rate so that the tow proceeds under a tension of about 1 mg./denier, squeezing the tow, which is then dried and cut. The two different synthetic polymers may be a homopolyamide and a copolyamide such as poly-#-capramide and a copolymer of #-caprolactam and hexamethylene-diammonium isophthalate or terephthalate; a homopolyester and a homopolyester ether such as polyethylene terephthalate and polyethylene paroxybenzoate; polypropylenes having different intrinsic viscosities.

Abstract: 224,697. Henshaw, S., Stonier, S., and Talk o' th' Hill Colliery, Ltd. Oct. 24, 1923. Ammonium sulphate. - Crude ammonium sulphate is neutralized while in a centrifugal and is subsequently automatically conveyed first to a hot-air drier and then to a crushing and bagging device. Weak ammonia solution from a tank 15, Fig. 5 is sprayed upon the crude salt in a centrifugal 5 and the neutralized ammonium sulphate is passed to a hot-air drier 6 whence it is transported by a conveyor 8 to a crushing and bagging device 17. In a modified form of apparatus Fig. 3, ammonia from a still 1 is passed into a saturator 2 and the crude ammonium sulphate forced through a pipe 3 on to a drainer 4. From the latter the salt reaches a centrifugal 5 in which it is treated with ammonia solution. The neutralized salt is transferred by means of a conveyor 8 to a hot air drier 6 fed with gases from a furnace 7 and is finally passed by another conveyor 11 to a crushing and bagging device 12. The preferred form of hot air drier comprises a vertical casing containing a series of superposed shelves swept by rabbles rotating about a vertical shaft through the axis of the casing, the salt in passing from the top to the bottom through apertures in the shelves being dried by hot gases which enter at the bottom.

Abstract: 389,862. Oil engines. RICARDO, H. R., 21, Suffolk Street, Pall Mall, London. Sept. 25, 1931, No. 26827. [Class 7 (iii).] In an internalcombustion engine of the compressionignition type having a spherical combustion chamber F comprising an uncooled plug member G, formed of heatresisting material of relatively low conductivity and arranged so as to be free from any substantial unbalanced stresses from pressure due to combustion, air, forced through a passage G<4> in the plug G, enters the combustion chamber tangentially and sweeps therearound and across the top of the plug G where, immediately prior to its again reaching the passage G<4>, it receives fuel sprayed towards a small area of the plug adjacent the passage by an injector H, the arrangement promoting the combustion of the layers of combustible mixture adjacent the walls of the combustion chamber and so tending to reduce or eliminate odour in the gases exhausted from the cylinder. The air is heated by contact with the part of the plug extending in the direction opposite to that of its flow and the combustible mixture by the part extending in the same direction. The upper portion of the combustion chamber may be provided with a liner K functioning in the same way as the plug G.

Title: Improvements in or relating to electric pulse lengthening apparatus
IPC: H03K5/00
Filed: 1952-10-30
Abstract: 704,318. Pulse modulation circuits; pulse lengthening circuits. GENERAL ELECTRIC CO., Ltd., BOWMAN, D. F., and WARD, P. W. Oct. 30, 1952, No. 27349/52. Classes 40 (5) and 40 (6) A pulse lengthening circuit comprises a pulse transformer the primary winding of which is tuned to "ring" on application of an input pulse train and a capacitor associated with the two secondary windings the voltage across the capacitor following the peak amplitudes of the input pulse train. Fig. 1 shows the application of the pulse lengthening circuit in the demodulator of a multi-channel pulse amplitude modulated telephony system. The incoming modulated pulse train, Fig. 2(a), of a given channel of the system is applied at 1 to the control grid of a gating valve 3 to the suppressor grid of which recurrent! channel gating pulses are applied at 2 so that the coincidence of a gating pulse and the desired channel pulse causes valve 3 to conduct and a pulse of current to pass through the primary winding of pulse transformer 5. This winding is tuned by capacitor 7 to a natural period of resonance which is approximately twice that of the channel pulse duration and is heavily damped by resistor 8 so that voltage pulses as shown in Fig. 2(b) are produced across the primary winding, the peaks of any given oscillation being proportional to the amplitude of the applied pulse producing it. If initially the free side of capacitor 19 is at a potential between that of earth and terminal 13 then during the peak 30 of each oscillation of Fig. 2(b) terminals 14 and 24 of secondary windings 10 and 11 swing negatively with respect to terminals 12 and 23 which are held at fixed potentials. Rectifiers 15 and 16 are rendered conducting and simultaneously rectifier 18 conducts, capacitor 19 discharging until the voltage across it is slightly negative with respect to earth. During the second peak 31 of each oscillation of Fig. 2(b) terminals 14 and 24 swing positive with respect to earth, rectifier 25 conducts and capacitor 19 is charged to a positive voltage between that of terminal 13 and earth which is proportional to the amplitude of peak 31 since winding 11 has fewer turns than winding 10. Thus a voltage as shown in Fig. 2(c) is produced at capacitor 19 so that the energy content of each pulse of the channel is increased. This waveform is now passed to a low-pass filter 27 and the modulating signal of the original pulse train of Fig. 2(a) is produced at terminals 28. In a modification terminal 13 is earthed and terminal 23 held at a negative potential thus enabling the low-pass filter 27 to comprise a single Class C tuned amplifier stage.
