Patent GB-715238-A (GB)
Title: Improvements relating to the production of hexamethylenetetramine
IPC: C07D487/18
Filed: 1952-06-18
Abstract: Hexamethylene tetramine is produced from formaldehyde-containing gases and ammonia by reacting them at boiling temperature in a saturated aqueous hexamethylene-tetramine solution, the water present and that formed in the reaction escaping in the form of vapour and the hexamethylenetetramine being separated in solid form.  Preferably the reaction is carried out continuously using a slight excess of ammonia.  The formaldehyde-containing gases may be the uncondensed gases obtained by the catalytic oxidation of methanol.  Instead of pure ammonia, ammonia-containing gas mixtures, e.g. carbamate gases produced in the manufacture of urea, may be used.  In the examples (a) methanol is reacted with water and air in the presence of a silver catalyst to form a gas mixture containing formaldehyde; the mixture is passed with ammonia into a saturated aqueous hexamethylene tetramine solution and hexamethylene tetramine is precipitated; (b) the process is carried out as in (a) except that ammonium carbamate is used instead of ammonia.

Abstract: 701,359. Preventing inductive disturbance. STANDARD TELEPHONES & CABLES, Ltd. June 20, 1952 [June 21, 1951], No. 15611/52. Drawings to Specification. Class 4U (4) [Also in Group XXXVI] A method of installing a carrier current communication cable consists in selecting the pairs or quads of the manufacturing lengths to form the individual electrical circuits between two repeater stations by measuring either their phase shifts or the differences of their phase shifts from an arbitrarily chosen reference value, or by measuring parameters on which said phase shifts or phase shift differences depend and connecting together the pairs or quads in successive manufacturing lengths in accordance with the results of said measurements to minimise the differences between the overall phase shifts of the individual circuits. This method may be employed either independently of, or in combination with, methods of balancing in accordance with impedance characteristics or other methods of balancing phase shift such as that of Specification 666,688. The Specification describes apparatus for carrying out the measurements (see Group XXXVI). If a high degree of phase shift equalization is desired, a phase changing network consisting of any kind of four-terminal network of which the attentuation is zero or low compared with its phase angle, and the characteristic impedance near to that of the cable, may be inserted in each or some of the circuits to introduce the necessary phase shift to achieve equalization.

Title: Improvements in or relating to light beam indicating apparatus
IPC: G01D7/06
Filed: 1946-05-23
Abstract: 626,642. Indicating-apparatus. STANDARD TELEPHONES & CABLES, Ltd., and GILLETT, W. F. H. May 23, 1946, No. 15652. [Class 106 (iv)] In a light beam indicator system of the type in which an angularly moving mirror reflects a projected beam on to a scale, there is interposed in the path of the beam a mirror or refracting medium so shaped that the resulting deflection on the scale bears to the deflection of the moving mirror a relationship which follows a different law from that which it otherwise would. Fig. 1 (Prov.) shows a mirror FM shaped to transform the approximately linear relationship between the scale and angle of deflection of a mirror galvanometer into a logarithmic one, SC being an arbitrarily chosen logarithmic scale, GM being the galvanometer mirror and the shape of the interposed mirror FM being obtained graphically by trial. This consists of drawing the paths of rays from GM to arbitrary points and then to the appropriate parts of the scale, e.g. G, O<SP>1</SP> O, to obtain the directions of the tangents to the mirror. Those points O<SP>1</SP>, M<SP>1</SP>, L<SP>1</SP>, &c. are chosen which enable a smooth curve to be drawn through the tangents. Fig. 2 shows how to obtain the shape of a block of refracting material to be used instead of a mirror. Two lines F<SP>1</SP>, F<SP>2</SP> are drawn parallel to the chosen scale SC and the outline of F<SP>2</SP> is modified graphically by using the formula Á sin i=sin r. As shown, a scale range of 0db-18db has been chosen, the ray corresponding to 18db being drawn normal to the block F<SP>1</SP>, F<SP>2</SP>, In a further embodiment (Fig. 6, not shown), the block is thicker and the surface F<SP>1</SP> is modified, F<SP>2</SP> being left plane and having the scale marked on it. Specification 453,279 is referred to.

Title: Improvements in or relating to standby systems embodying storage batteries
IPC: H02J7/04
Filed: 1966-04-07
Abstract: 1,147,882. Charging and discharging batteries; standby systems. AMPHENOL CORP. 7 April, 1966 [8 April, 1965], No. 15698/66. Heading H2H. The charging of a battery 20 in a standby electricity supply system is determined by the discharge of a timing battery 25 which is charged by the battery 20 voltage or a fraction of the discharge current. A load 4 and parallel connected relay 41 is normally energized from a rectifier unit 1, and from battery 20 through a diode 13 on cessation of the supply which also de-energizes a relay 28 closing contacts 30 which supplies a charging current through resistor 27 and contacts 7, 17 to battery 25. If the load 4 is not constant, the battery 25 may be charged from a series load resistor. When the battery 20 discharges to a determined voltage, relay 41 de-energizes opening contacts 17, 19 and closing contacts 16, 18, isolating the timing battery. When the supply is restored relays 28, 41 are reenergized, breaking the circuit to battery 25 and reconnecting it through contacts 6, 17 to a discharge circuit comprising resistors 34-37 which maintain a transistor 38 conductive and hence a relay 33 energized until the battery 25 has discharged. Meanwhile battery 20 has been recharged through contacts 8, 15, 19 and a resistor 11. A fraction of the charging voltage is also fed to an indicator lamp 22. The charging circuit 5 may have a higher output voltage than circuit 2. When the battery 25 potential falls, transistor 38 blocks and relay 33 is de-energized, breaking the charging current circuit through contacts 9. A manual switch 21 provides for initial charging of the battery 20 through resistors 24, 11, and contacts 9.

Title: An improved method for the manufacture of moulded articles of fibrous aqueous pulp
IPC: D21J3/00
Filed: 1949-06-17
Abstract: 691,529. Moulding hollow articles of fibrous material. MULLER, K. June 17, 1949, No. 16173/49. Class 87 (ii). A hollow fibrous moulded article of cylindrical prismatic or slightly conical shape, which has been deposited from fibrous aqueous pulp on a moulding sieve with rapid removal of water by the use of pressure, is subjected, on or off the moulding sieve, to a preliminary drying which reduces the water content to 30-70 per cent. by weight. It is then removed from the e moulding sieve, if this has not been done, and 'compressed to one half or less of its original thickness and simultaneously subjected to final drying, this simultaneous action being effected by causing the article to be gripped or squeezed in a heated pressing device, the gripping or squeezing progressing along the tubular part of the article until finally substantially the whole of the tubular part is under compression. The simultaneous compression and heating may be effected by using the device shown, which comprises a die a, on which the preliminarily-dried article d is placed, and a hollow plunger b which descends to compress the article, gradual compression being effected by the conical edge c on the plunger. The die and plunger are heated by bands e, f. Steam escapes through passages g in the die. Similar passages may be provided in the plunger b. A sharp edge h on the die co-operates with the edge c to trim the edge of the article. The heating may be such that the drying progress from one side of the article to the other, e.g. one of the two pressing tools is not heated or only slightly heated. The edge e may be separately heated. The conical edge c may be not on the plunger but on the die. The deposition on the moulding sieve may be effected under super-atmospheric pressure, the pulp being admitted to the sive from a closed supply container or from a pump; when a pump is used its piston may be formed as a moulding stamp which presses and moulds simultaneously. Alternatively, the deposition may be effected by pressing the pulp on to the sieve by means of a moulding sieve. The preliminary drying may be effected by hot air applied to the article either before or after it has been removed from the sieve. Reference has been directed by the Comptroller to Specification 671,692.
