Title: Improvements relating to contour forming machines
IPC: B23Q35/18
Filed: 1939-07-16
Abstract: 530,922. Grinding. ARCHDALE & CO., Ltd., J., and WRIGHT, I. H. July 6, 1939. No. 19675. [Class 60] [Also in Group XXII] Machines for copying by milling or grinding are described with reference to end milling an irregular aperture in a sleeve. The sleeve is mounted on a carrier movable in four directions by fluid pressure cylinders with valves arranged so that the use of pressure in one cylinder due to the pattern being arrested by the tracer causes admissicn of fluid to another cylinder and so on. The sleeve is secured to a mandrel mounted to have oscillating and sliding movements in bearings and carrying a pattern sleeve. The tracer and cutter spindle are both fixed in position. The operation is started by admitting pressure to the cylinder C<SP>1</SP> by a hand operated valve (not shown). The cylinder C<SP>3</SP> exhausts through the port 3a of the valve V<SP>1</SP>. The valves V<SP>1</SP> to V' are normally closed by springs S. The initial pressure in the cylinder C<SP>1</SP> opens the valve V<SP>1</SP> by fluid ported at 4 to the cylinder X and this pressure is sufficient to open the valve to the position illustrated with reference to the valve V<SP>2</SP>. When the pattern m contacts with the follower roller j the resulting rise of pressure moves the valve V<SP>1</SP> to the fully open position illustrated and pressure fluid passes by the port 6 to the port 5 of the valve V<SP>2</SP>, causing the loose piston v to open the valve to the position shown admitting pressure fluid from 2 to the port 2a and cylinder C<SP>2</SP>. On the movement of the pattern by this cylinder being arrested, the valve V<SP>2</SP> opens fully, admitting pressure in the manner already described to the cylinder C<SP>3</SP>. This exhausts the cylinder C' and allows the valve V<SP>1</SP> to close. Rise of pressure in the cylinder C<SP>3</SP> opens valve V<SP>4</SP>, and rise of pressure in the cylinder C' re-opens the valve V<SP>1</SP>, the cycle continuing as required by the outline to be cut. More than four cylinders may be employed to provide for movements in an increased number of directions.

Title: Arrangements for controlling noise in electric communication systems
Inventor: HOLLAND JOHN DOUGLAS
IPC: H03G3/34
Filed: 1959-06-09
Abstract: 852,863. Radio receiving systems. STANDARD TELEPHONES & CABLES Ltd. June 9, 1959, No. 19697/59. Class 40(5). Relates to arrangements for distinguishing between noise and intelligence signals in electric communication systems and is based on the fact that the number of transitions per second across the zero axis of a speech wave (the transition rate) falls between well defined maximum and minimum limits in a circuit having a given bandwidth. If noise is present the maximum transition rate increases, and a predetermined increase depending on the permissible amount of noise may be made to operate a switch to give an alarm or carry out a control. In a transition-rate discriminator an audio signal is supplied to a limiter 4 to produce a rectangular wave which is differentiated at 5. The resulting pulses are supplied to a circuit 6 which suppresses all the pulses of one sign and supplies the others to an integrator 7. The integrator 7 thus stores up a potential proportional to the mean pulse frequency which is compared at 9 with a reference voltage supplied from a source 8, a control voltage being supplied to an output conductor 10 when the stored potential increases to a value above the reference voltage. Transistors may be used to perform the various functions, Fig. 5 (not shown). In a radio transmitting and receiving station the arrangement may be used to mute the receiver when the transmitter is in operation Fig. 3 (not shown). Since the transition rate will be high when noise is present without any received speech waves. Also the transition rate discriminator may be adjusted to disconnect the receiver if the noise level increases sufficiently to make the received speech unintelligible. In a further application, Fig. 4 (not shown) each receiver in a radio diversity system is provided with a transition rate discriminator. It is stated that if the pulses produced by the differentiator 5 are supplied to a telephone receiver intelligible speech is reproduced. Specification 808,461 is referred to.

Title: Improvements in and relating to air brakes for vehicles
Inventor: TOROCSIK LASZLO
IPC: B60T15/04
Filed: 1964-05-13
Abstract: 1,063,845. Air-brake systems. CSEPEL AUTOGYAR. May 13, 1964, No. 19854/64. Headings F2E and F2F. A set of air-brake control valves for motor vehicles constituting a brake control valve system operable by a foot pedal P or hand lever is sub-divided into a structural unit 32 containing the valve or valves 20 controlling communi-  cation between inlet 21 from a pressure reservoir and an outlet to brake cylinders 22; a structural unit 31 containing a piston 15 transmitting pedal motions to the valves; one or more valve units 33 insertable between the two units abovementioned for controlling one or more additional brakelines as at 18; and a special valve unit 34, attachable to the piston unit 31, controlling the brakes of a trailer. When pedal 1 is depressed a rocker 2 pivots at 28 and lifts a tubular plunger 3 allowing the lower valve of the twin element 4 to rise and seat at 10 thereby cutting off the pressure air supply from 15 to the trailer brake-pipe 6. Further upward movement of the tube 3 unseats the upper valve 4 therefrom and allows air to escape from the brake pipe 6 (note full lines with arrows). Air from chamber 7 also escapes, so that the pressure in chamber 9 pushes up the piston 10 against the spring 11 to re-close the upper valve 4 and cut off the air outlet through tube 3. The precompression of spring 11 can be adjusted to ensure that the piston 10 only rises after a predetermined pressure drop in the trailer brake pipe. The main valve 16 operates after the trailer brake has been applied, the pedal 1 having depressed the piston 15 on to the upper valve of the twin element 16 cutting off communication between rear-brake cylinders of the tractor vehicle and the atmosphere. Further depression of the piston 15 lifts the lower valve 16 off its seating and permits compressed air from 17 to flow to the vehicle rear-brakes by way of 18. This pressure acts on the underside of piston 15 against the spring 14 and causes the lower valve 16 to return to its seat. The pressure applied to the rear brakes also acts on a piston 19 which bears on the upper valve of twin element 20 and admits air pressure from 21 to the front brakes of the tractor vehicle by way of 22. On release of the brake pedal the valves and pistons return to the positions shown in Fig. 4. The trailer can also be braked by moving a hand lever 25 in the direction shown by the arrow. In this case the eccentric 24 raises the pivot 28 with the rocker 2 so that they pivot as a whole about 29 to lift the plunger 3 as before. The lead of the trailer brake over the tractor brakes can be adjusted by turning a stop-screw 30 which moves the lever 25 and with it the eccentric 24. The various valves are constructed as units which can be built into a number of combinations which are described in the Specification, the casings of the units being adapted for interconnection by known means.

Title: Improved detergent compositions
IPC: C11D3/02
Filed: 1957-06-24
Abstract: A process for improving the non-caking characteristics of a spray-dried granular detergent composition, which comprises at least one water-soluble anionic synthetic detergent of the sulphuric reaction product type and at least one hydratable alkali metal phosphate, consists in agitating the granules while simultaneously spraying them with an aqueous solution of magnesium, zinc or aluminium sulphate in an amount such that such sulphates, calculated as anhydrous sulphate, comprise 1-10 per cent, preferably 2-4 per cent, of the granules The water content of the granules is thereby raised to the amount of 12-25 per cent, and usually 14-17 per cent. The process yields a product, the granules of which have a coating of one or more hydrated double phosphates of the alkali metal with zinc, magnesium, or aluminium.  The detergent used may be a sodium alkyl sulphate, but is preferably a sodium polypropylene benzene sulphonate averaging 12 carbon atoms in the polypropylene group, in an amount of 20-40 per cent by weight of the composition.  The phosphate, which may be a tripoly-, pyro-, or orthophosphate or mixture thereof, is usually present to the extent of 10-60 per cent.  The concentration of the inorganic sulphate solution applied to the granules is suitably 18-22 per cent.  The final composition generally contains 10-30 per cent of sodium sulphate, together with minor amounts of carboxymethylcellulose, sodium silicate, coconut fatty acid ethanolamide, fluorescent dyes, colouring, and perfume.  The inorganic sulphate solution may suitably be applied by spraying either simultaneously or sequentially with the addition of such adjuncts in conventional rotating mixing drums. Specification 614,044 is referred to.

Title: A process for the manufacture of artificial silk threads, bands, films and the like from viscose
IPC: D01F2/08
Filed: 1922-07-20
Abstract: In the manufacture of artificial silk, films, &c. from viscose an extract of colloidal character obtained from mallow roots or linseed is added either to the precipitating bath or to the viscose itself, or to both.  The extract is obtained by boiling with water for several hours, then adding the other constituents of the precipitating baths, the heating being continued for some time.  The extract may be rendered colourless by the addition of bleaching-agents such as hydrosulphites, hydrogen peroxide, or sodium peroxide or perborate, either during or preferably after the extraction process.  The Specification as open to inspection under Sect. 91 (3) (a) includes the use of extracts of the parts of plants generally, such as the wood, stalks, leaves, needles, roots, or fruits; and the extracting medium may be water, solutions of acids or of substances having an acid reaction, or solutions having an alkaline reaction; thus, the water extracts are obtained by boiling the material with water under pressure, acidifying the extract, heating preferably to boiling point, filtering, concentrating if necessary, preferably in vacuo; and a similar procedure is adopted in the case of acid and alkaline extractions, a suitable acid extracting-medium being 5 per cent sulphuric acid; and suitable alkaline mediums, solutions of sodium hydrate, soda, ammonia, and "the lyes precipitated in the manufacture of viscose silk and soda-cellulose."  Of particular value in the process is "pine-needle extract" obtained from the needles of conifers, such extract containing terpene-like substances, and extracts deficient in these may be improved by the addition of p  turpentine, turpentine oil, "pinon," and the product obtained by reacting with acids on pinene, pinol, &c.  It mentions also that salts of ammonia, triethylamine, pyridine, &c. may be added to the precipitating bath.  This subject-matter does not appear in the Specification as accepted.
