Title: Process for producing endless bundles of artificial fibres
IPC: D06M15/70
Filed: 1929-11-13
Abstract: The tensile strength, both wet and dry, of viscose fibres in the form of bundles particularly bundles of high total titre such as are referred to in Specification 311,399, [Class 2 (ii), Cellulose &c.], is increased by passing the incompletely-coagulated fibres in the acid moist state on leaving the precipitation bath, through a heated water bath and simultaneously subjecting them to a tension as high as possible. The temperature of the bath may be 70-100 DEG  C., the length of travel therein may be 2-12 metres, and the tension may be produced by passage over rods or rolls, or over a plurality of rollers running at different speeds.  During passage through the hot water bath, conversion to cellulose hydrate is completed.  The bundles are subsequently washed, desulphurized, bleached and finished.  The Specification as open to inspection under Sect. 91 (3) (a) refers to the stretching of the bundles of fibres without passage through the heated water bath, and also to stretching during a prolonged passage through the air.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in nuclear reactors
IPC: G21C5/08
Filed: 1961-09-28
Abstract: 912,731. Nuclear reactors. BABCOCK & WILCOX Ltd. Sept. 28, 1961 [Sept. 29, 1960], No. 34815/61. Class 39 (4). A nuclear reactor has a core enclosed within a pressure vessel and includes a body of moderating material containing coolant channels, there being a large drop in the coolant pressure along the channels, and to prevent the coolant inlet pressure being applied to the underside of the core the coolant is fed through ducts from an inlet chamber to the lower ends of the channels. The reactor core 2 includes columns of superimposed moderator blocks 1 located on a support 6 within the pressure vessel 5 provided with a coolant inlet duct 3 and an outlet duet 4. A partition wall divides the vessel into a lower chamber 10 and an upper chamber 11. Coolant supply ducts 8 feed coolant directly from the chamber 10 to the coolant channels 9. The horizontal passages 13 allow coolant to flow from the coolant passages 9 to the passages 15, the throttling effect caused by the coolant passing between the moderator blocks reduces the pressure of the escaping coolant to that of the outlet pressure, resulting in the pressure of the coolant around the moderator blocks being substantially uniform. In Fig. 2 (not shown), various arrangements are indicated for the alignment, support and jointing of the moderator blocks 1, in which the lower surface of an upper block is formed with an annular recess within which fits an upper end part of an annular flange formed in the subjacent block. This block may also be provided with a castellated, peripheral annular flange having radial channels or slots. In another arrangement, a centring sleeve is fitted into the annular recesses, while in a further arrangement the centring sleeve supports as well as aligns the channels. In another arrangement, in addition to the centring sleeve a ring with radial apertures is provided.

Title: Improvements in or relating to an exhaust device for a combustion engine
IPC: F01N3/22
Filed: 1971-07-27
Abstract: 1292255 Treating exhaust gases AUTOMOBILES PEUGEOT and REGIE NATIONALE DES USINES RENAULT 27 July 1971 [4 Aug 1970] 35075/71 Heading F1B Additional air for post-combustion of exhaust gases is injected into the exhaust pipe of an engine upstream of an after-burner, by a pump driven at a speed proportional to engine speed, and having a re-circulation duct in parallel with the pump, the re-circulation of air from the output to the input of the pump being governed by a valve in the duct controlled by the depression prevailing in the engine induction pipe. The pump 8 draws air from the air cleaner 2 and delivers it through a pipe 11 to the exhaust pipe 6, upstream of the after-burner 7. The recirculation duct 12, 13 contains a valve 14, connected by a passage 15 to the induction pipe 5, downstream of the throttle valve 4 of a carburetter 3. The depression in the induction pipe acts on the valve 14 so that there is no recirculation of air when the absolute pressure in the induction pipe is high IC when the engine is operating at full load. Alternatively, when the pressure in the induction pipe falls, the valve opens to allow some re-circulation of air and and a reduction of the amount of air injected into the exhaust pipe. The reduction is less than proportional to the exhaust gas flow to allow for the increase in the content of carbon monoxide and unburnt hydro-carbons at port throttle openings. Under high deceleration when the pollutants are a maximum the opening of the valve 14 is limited to maintain a predetermined air supply to the exhaust pipe. The valve 14 comprises an enlarged section 18 containing a butterfly valve 26 operated by a lever arm 27, to which are connected one end of a tension spring 30, and a hook 29 projecting from a piston 21 clamped at the middle of a rolling diaphragm 19. The edge of the diaphragm is held between the flanges of two cylinders 16 and 17. The passage 15 communicates with a sealed chamber 23 on one side of the diaphragm, and there is an opening 25 in the cylinder 17 so that the other side of the diaphragm is subject to atmospheric pressure. In a modification the lever 27 has a broad curved upper end to which the spring and the piston are connected by flexible cables. In a further modification the piston carries a piston rod on which a generally conical valve member is mounted. The valve member co-operates with a fixed valve seat to vary the volume of air re-circulated.

Title: Method of treating refuse and the like
IPC: B09B3/00
Filed: 1928-11-29
Abstract: 301,427. Terwagne, A. J. Nov. 29, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Refuse, dust-bin, treating; manures.- Refuse is first dried and then heated to a higher temperature to yield combustible gases and carbon. The furnaces used are of truncated conical form and elliptic cross-section and are arranged obliquely so that the weight of the material aids its discharge. The drying furnaces are heated to a temperature not higher than 120‹ C, gases being withdrawn by suction and delivered to the combustion hearth. The refuse falls from the drying furnaces to a pit from which it is lifted by a bucket elevator to a screening drum. Material which does not pass through the screen is delivered into an electromagnetic conveyer band, which retains pieces of iron, and thence to a hand-sorting band. The material left on the sorting band consists mainly of cellulose and is passed to carbonization or distillation furnaces, heated to a temperature of 350‹ to 400‹ C. The gases from these furnaces are in part condensed and the non-condensable portion is used to heat the furnaces. The water used for spraying the charcoal will dissolve potash which can be recovered and added to the powder passing through the drum screen, which is stated to have a fertilizing value.
