Heading C2U. 3 - Oxo - 4,6 - dehydro - 19 - nor - steroids are prepared by treatment of 3-oxo-5( 10),7-dehydrosteroids with an acid or a base. If a base is used a proportion of the novel 3-oxo-4,6-dehydro- 8α,9α,10α-19-nor-steroids are produced in addition to those of normal, i.e. 8#,9α,10#, configuration. They may be converted to the normal isomers by acid treatment. The starting materials may be prepared by reaction of 3 - hydroxy - 2,5(10),7 - dehydro - steroid 3 - ethers or 3 - oxo - 5(10),7 - dehydro - steroid 3-ketals with a weak acid. If a strong acid is used direct conversion to the 3-oxo-4,6-dehydro- 19-nor-steroids is achieved. Other groups in the molecule may be hydrolysed during these processes, e.g. a 17-ketal to a 17-oxo group. The products may be reduced to 3-oxo-4-dehydro- 19-nor-steroids by the action of metal-ammonia or metal-amine reducing systems; the preparation of 19-nor-testosterone by this method is described.

Title: Improvements in the treatment of synthetic polyamide textile materials
Inventor: JONES GWILYM THOMAS
IPC: D06M15/11
Filed: 1963-07-04
Abstract: Synthetic polyamide textile materials are rendered antistatic and given an increased moisture absorbency and a reduced tendency to soiling by treating them from an aqueous medium with a hydroxyalkyl derivative of cellulose or starch, a cross-linking agent or a resin precondensate which reacts under acid conditions and a catalyst which is an acid or acid-generating substance and then drying and heating. The hydroxyethyl, hydroxypropyl and dihydroxypropyl derivatives of cellulose or starch may be used. Suitable cross-linking agents and resin precondensates are formaldehyde, acrolein, glyoxal, condensation products of formaldehyde with urea, thiourea, dicyandiamide, amides, amines, carbamates, aminotriazines, urons, ureins, ureides, imidazolidones, pyridones and triazones and lower alkyl ethers thereof, methylol derivatives of nitrogen containing polymers such as water-soluble urea/formaldehyde polycondensates, polyacrylamide and addition copolymers containing acrylamide and lower alkyl ethers thereof, acetal condensation products of formaldehyde, acetaldehyde, glyoxal, malondialdehyde, succindialdehyde, adipaldehyde, hydroxyadipaldehyde or terephthaldehyde with ethylene glycol, diethylene glycol, glycerol, pentaerythritol or dipentaerythritol.  The catalyst may be oxalic acid, tartaric acid, zinc chloride, a mineral acid salt of an amine, ammonium chloride, sulphate or thiocyanate or magnesium chloride.  Up to 50% by weight of the hydroxyalkyl derivative of cellulose or starch may be replaced by a condensation product of an alkylene oxide with a polyamide.  The hydroxyalkyl derivative of starch or cellulose, the cross-linking agent or resin precondensate, the catalyst and the condensation product of an alkylene oxide with a polyamide may be applied to the polyamide fibres separately or from the same aqueous solution and the fibres then dried, e.g. at 50 DEG -110 DEG C., and may be heated at a temperature of 50 DEG -230 DEG C. for from 1 second to 1 hour.  The fibres may subsequently be rinsed in water, washed in a hot solution of a detergent which may also contain an alkali, rinsed with water and dried.  The polyamide fibres may be in the form of filaments, fibres, tows, yarns or non-woven, woven or knitted fabrics.  The process may be carried out in conjunction with or after other chemical or mechanical finishing operations such as those used to confer resistance to shrinkage or creasing, handle or surface lustre, water-repellency and optical brightness. Example 3 refers to the treatment of woven nylon carpet. Specifications 799,153, 907,701 and 953,754 are referred to.

Abstract: 1,223,685. Sheet forming. STOREY BROS. & CO. Ltd. 7 June 1968 [8 June, 1967], No. 26588/67. Heading B5A. In a process to form an assymmetrical article having a sloping upper surface, a heat softened thermoplastic sheet 10, of e.g. P.V.C., is initially blown into a bubble to pre-stretch it. Part of the prestretched sheet is then applied to the sloping surface 18 of the mould 16 by a plug movable in a direction normal to the surface 18, and the sheet is finally sucked or blown into overall conformity with the mould. By moving the plug in such a direction more sheet becomes available for subsequent application to the larger side of the mould than is the case when the plug moves vertically (see Fig. 3, not shown). A better distribution of material is thus ensured.

Title: Improvements in methods and apparatus for frequency multiplying
IPC: H02M5/20
Filed: 1952-10-23
Abstract: 729,065. Changing frequency. ELECTRICITE DE FRANCE. Oct. 23, 1952 [Oct. 24, 1951], No. 26662/52. Class 38 (2). The frequency f of an electric oscillation is multiplied by producing p oscillations all of frequency f, each phase displaced by  2#/p from   the preceding one, applying the p oscillations to non-linear resistors to produce multiple harmonic components of frequency f including the kp-th harmonic, superimposing all these oscillations whereby the first p harmonic components cancel out and selecting the. kp-th harmonic component. For multiplying the frequency by five, the input of frequency f = 50 is fed through transformer T to five rectifiers R 1 -R 5 , each of which produces a half-wave rectified output, the phases of the outputs being successively displaced by angles of 2#/5 by in-   ductors L<SP>1</SP>-L 4  and capacitors C 1 -C 4 . An output of frequency 5f = 250 is selected by means of a tuned circuit CB from the sum of the outputs which is a complex of waves of frequencies 5f, 10f, &c.

All transducers are used as transmitters, and just the further one as a receiver-or vice versa. Echo signals received are analysed to extract acoustic velocity, seattering and multiple-reflection information about an inspected object. The invention is applicable to medical diagnosis, echo signals being displayed on a C.R.T., film or chart as a type A or range/bearing display. By using all the transducers in turn for transmission and a central transducer only for reception, or vice versa, different echo times and amplitudes are obtained from one and the same reflecting surface. In the described embodiment the echo signals are processed by analogue or digital means to (a) bring the echoes from a common surface into time-alignment, (b) sum such echoes to enhance the display of reflecting surfaces inclined to, as well as normal to, the ultrasonic beam axis, (c) analyse the time differences between echoes from a common surface to determine the acoustic velocity in a region being investigated and to detect multiple reflections which might otherwise give rise to ambiguity, and (d) analyse the amplitude differences between echoes from a common surface to determine the roughness of of the surface and its inclination. The transducers may have their active faces coplanar or arranged on the surface of a solid of revolution. The annular transducers may be segmented.

Abstract: 1287742 Slides IAN NICHOLS Ltd 26 Aug 1969 [7 June 1968] 27147/68 Heading B3B [Also in Division F1] A double acting hydraulic ram 1 for moving a cross slide 7 is secured to a fixed frame 9 and is supplied by a pump 9 delivering through reversible distributing valve 8 of the closed centre spool type and which is biased to an open position by a double acting compressed air motor 16 linked thereto by levers 10, 11 and the control valve 8 is subjected to a controlled opposing bias provided by the reaction force of a cylinder 21 mechanically connected to lever 10 when fluid is displaced therefrom through a needle valve 24 by means of a piston 22 connected by its rod 20 to the slide 7 and whereby a preselected ram speed is achieved by balancing the two biases. In operation compressed air is supplied through a pressure control valve 18 and reversing valve 19 to say the left hand side of motor 16 which thus moves control lever 11 anti-clockwise and displaces valve 8 and the connected cylinder 21 to the right thereby feeding hydraulic fluid to the right hand end of a cylinder 4 so as to extend slide 7 and connected piston 22. The reaction force provided by the back pressure set up by the partly open needle valve 24 and acting against the left hand end of cylinder 2 serves to partly close valve 8 to a position where the reaction force and the ram moves at a constant speed depending on the setting of valves 18, 24. If during the forward stroke the slide offers an increased resistance so that the ram speed falls, the reaction bias automatically decreases and the control valve 8 assumes a more open position resulting in the ram speed being restored.

In an electric selective signalling system employing the synchronous selector principle of audio-frequency mains superimposition, in order to lessen the chance of spurious pulses actually passing via the synchronous distributer at the receiver to the subsequent switch-gear the distributer arm is held stationary between successive pulse periods and is then swept across a contact at a speed higher than that with which it would normally cross a contact when rotating at a constant speed. This results in electrical contact between the distributer arm and the distributer contacts being made for periods of time, Fig. 4, appreciably shorter than pulse periods, Fig. 3, and considerably shorter than the normal contact periods, Fig. 2. The step-bystep movement of the distributer arm W, Fig. 1, is effected by driving the arm from the synchronous motor S via a cam N, a rocking member H and a ratchet wheel R driven by a pawl V integral with the member H. As the synchronous motor rotates so also does cam N causing the member H to rock about its supporting shaft a, on which it is freely pivoted, which, in turn, via pawl V drives the ratchet wheel R, the shaft a and the distributer arm W.
