Patent GB-368401-A (GB)
Title: Improvements in the recovery of nitrogen oxides from nitrosyl chloride
IPC: C01B21/20
Filed: 1930-12-10
Abstract: Nitric oxide is recovered from waste gases containing nitrosyl chloride and chlorine, which are produced in the manufacture of potassium or other nitrates by the reaction of the corresponding chlorides with nitric acid or nitrous gases as claimed in the parent Specification, by conducting these gases over heated iron or ferric nitrate.  Nitrogen oxides free from chlorine are obtained.  A temperature of 300 DEG  C. may be employed.  The necessary heat may be introduced with the reaction gases, the heat liberated during the combustion of ammonia being utilized.  The iron or ferric nitrate is converted into ferric chloride.

Title: Direct-current machine arrangement
IPC: H02K23/22

Abstract: 1,223,031. Exciting D.C. machines; control of D.C. motors. SIEMENS A.G. 5 Aug., 1968 [5 Aug., 1967], No. 37333/68. Headings H2A and H2J. A direct current machine has two magnetically coupled field windings and a rectifier connected to one of the windings to excite that winding with rectified current derived from an A.C. supply, the other winding being shortcircuited to tend to smooth the exciting current. A first field winding W1 of a generator G has connected thereto two thyristors N1, N2, of which either N1 is fired during one half-cycle of the A.C. supply or N2 is fired during the other half-cycle. A short-circuited second field winding W2, which may either be wound round all the stator poles or may comprise individual windings on the different poles, serves to smooth the rectified current and also assists in switching off the operating thyristor when the A.C. supply changes sign. The sign of the output voltage depends on which of the thyristors N1, N2 is operational. The generator may form part of a Ward-Leonard set.

Metal to be drawn through a die 3 is passed through a tubular seal 4 and a lubricant pressure vessel 1, into which lubricant is pumped at least during the initial period of the drawing operation, so that lubricant is drawn into the vessel 1 from a pre-lubrication bath 12 to generate a lubricant pressure within the vessel 1 at least equal to a major proportion of the tensile strength of the metal. When sufficient pressure has been generated, the pump supplying lubricant through an inlet 6 may be switched off. The clearance between the seal 4 and the metal is 0À001-0À004 inch. The lubricant, e.g. mineral oil, glycerol, polyglycol, may be heated prior to being pumped to the vessel 1. A cooling coil 5 may be provided adjacent the tubular seal 4, which may be of tungsten carbide having a bore of constant cross-section of one inch length.

In an air cooled cylinder head, cooling air passages are arranged so that some of the air strongly heated by contact with the hottest portions of the head is guided away to cooler portions of the head and some of the air which initially contacts cooler portions of the head is subsequently guided towards the hottest portions. In Fig. 1 some cooling air entering at level e flows directly into a passage 17 bored in the solid, highly heated, base portion 1 of the head so as to emerge at the side of the head. Additional cool air is diverted by a baffle 19 into a second passage 18 in the base 1. Above the base 1, one air stream 21 flows directly around the precombustion chamber wall 6, Fig. 3, into a passage 23 between the wall 10 of the inlet and exhaust passages and a second cooler stream 20 is diverted by a lip 25 to mix with the hot stream in passage 23. At a higher level, Fig. 5 (not shown), a stream of air 29 heated by contact with the wall 6 is diverted to the side of the cylinder head. In a modification, Figs. 6 and 8, a portion of the main air stream flows round a fuel injector 41 into passage 23 whilst another portion is deflected outwards to the side of the head. Some of the cooler air stream 47 flowing along the side of the head is diverted into the passage 23 and into entrances 43 of a passage 42 bored through the solid base 1 of the head.

A continuous band 54, having adhesive material adjacent one edge is formed into a tube by being fed into a continuous belt 48 curled into cylindrical form by curling means, e.g. platens 28-30 (Fig. 5). The band is pressed outwards against the belt, with the opposite edges overlapping and the adhesive sandwiched between them, by compressed gas introduced through holes 60 (Fig. 2, not shown) in tube 58, the loss of gas being limited by bands (62). If heat sensitive adhesive is used the width of the belt is such that its edges 50 do not meet, leaving a gap for heating element 26, which fits into the channel between platens 29 and 30. The overlapping band sections, with the adhesive sandwiched between, are pressed against elements 26, and sealed together, thus forming the tube. Where pressure sensitive adhesive is used, the heating element is dispensed with, platens 29 and 30 are replaced by platen 66 (Fig. 6, not shown) and belt 48 has sufficient width to form a complete cylinder.
