IPC: B26D1/24
Filed: 1966-06-01
Abstract: 1,148,004. Rotary cutting apparatus. HENRY SIMON Ltd. 15 May, 1967 [1 June, 1966], No. 24430/66. Heading B4B. A rotary anvil assembly for rotary die cutting units comprising a frame 20 having an anvil roll 4 rotatably mounted therein and covered by a resilient material 6, e.g. polyurethane, and means 66, 76 for axially adjusting the position of the roll in the frame. The roll 4 is provided at one end with a stub shaft 22 mounted in a bearing 24 which is eccentrically carried by a housing 26. A gear 58 is rotatably mounted on a hub 60 and adapted to rotate the roll 4 via a stud-and-plate coupling 40, 42, 44, 46. The end of stub-shaft is coupled by a yoke 68 to a threaded shaft 74 rotatable by a hand wheel 76.

Title: Improvements relating to vapour generators
IPC: F22B35/06
Filed: 1945-09-21
Abstract: 629,233. Forced-flow steam &c. boilers. FOSTER WHEELER, Ltd. Sept. 21, 1945, No. 24512. Convention date, Sept. 21, 1944. [Classes 123(ii) and 123(iii)] A forced-flow steam &c. boiler comprises a vertical setting 10 which has as its lower end a furnace 11, fired by a burner 12, and locates, between the furnace 11 and a flue 21, an economizer section 18 and a combined steam generating section 19 and desuper-heater 20 and, also, around said furnace, a preliminary radiant superheater 22 and a final superheater having a radiant section 26<SP>1</SP> and a convection section 26". Preferably the superheater tubes 22, 26<SP>1</SP>, which are shown diagrammatically, line the side walls and bottom of the furnace and are disposed alternately therearound. Water is supplied to the economizer 18 by a pump 16 through a valve 33 which is controlled by the steam pressure in the boiler outlet pipe 27, through a line 35 and bellows 34, in such a manner that an increase in pressure will effect movement of the valve towards its closed position and vice versa. From the economizer the water flows through the generating section 19, and steam from the latter passes through the preliminary superheater 22 to a junction pipe 23 provided with two valves 24, 25 which control the flow to the final superheater 26<SP>1</SP>, 26<SP>11</SP> and desuperheater 20 respectively and are actuated by a thermostat 29 in the outlet pipe 27 through a line 30 and bellows 31, 32; an increase in the final steam temperature will tend to close the valve 24 and open the valve 25 to cause an increased proportion of steam to flow through the desuperheater and, similarly, a decrease in temperature will reduce this quantity. The supplies of fuel and air to the burner 12 through the pipes 13, 14 may be controlled by the steam pressure acting upon valves 38, 41 in the said pipes. A modification is described in which the boiler furnace has two separately-fired chambers, the firing in one being controlled by the final steam pressure, and in the second, or superheater chamber, by the steam temperature.

Title: Improvements in high density silicon
IPC: C22C28/00
Filed: 1963-06-21
Abstract: A new dense form of silicon (Silicon II), having a density in excess of 2.42 g./c.c. but less than 2.59 g./c.c., and a cubic unit cell of edge length 6.60 <\>rA containing 16 atoms of Si per cell, is produced by submitting ordinary silicon (Silicon I), having a density of 2.32 to 2.42 gm./c.c. and a cubic unit cell of edge length 5.43 <\>rA with 4 atoms of Si per unit cell, to elevated pressure, e.g. 110-190 kilobars, or elevated pressure and temperature, e.g. 25-800 DEG  C. until the desired transition to Silicon II is accomplished. The pressure and temperature may be raised simultaneously, separately or they may be raised alternately in stages.  The pressure and temperature are reduced before recovering the Silicon II which is apparently stable under ambient pressure and temperature conditions. Heating Silicon II causes the density to decrease towards that of Silicon I but the change is not complete or immediate under controlled conditions. Heating the Silicon II to 180 DEG  C. for 45 minutes causes a lowering of the density and also produces a further form of silicon in that the crystal structure becomes hexagonal and wurtzite in type.  The apparatus used is a modified form of the standard high pressure apparatus.

Abstract: 1,185,356. Oxidizing acrolein polymers. DYNAMIT NOBEL A.G. 31 May, 1967 [1 June, 1966], No. 25048/67. Heading C3P. [Also in Division D1] An acrolein homopolymer or a binary copolymer of acrolein and methacrolein containing up to 20 weight per cent of methacrolein is oxidized in an aqueous alkaline medium in the presence of an oxidizing agent, whereby from 10 to 70% of the aldehyde groups of the homo- or copolymer are converted to carboxyl groups which are present in the form of their alkali metal salts. Suitable oxidizing agents are CuO, Cu(OH) 2 ; Au, Ag, Hg, Pt, Ru, Rh, Pd, Os and Ir and oxides or hydroxides of these metals and of Pb, Mn, Re, Fe, Co and Ni; O 2  and freeoxygen containing gases; and KMnO 4 . The medium is rendered alkaline by, e.g. the hydroxides, carbonates or bicarbonates of Na or K, in which case the product is isolated by neutralization of the medium with CH 3 CO 2 H, concentration by evaporation and precipitation of the polymer as an alkali metal salt using methanol or ethanol. Alternatively the medium is neutralized with, e.g. HC1, H 2 SO 4  or HNO 3  to precipitate the polymer as the free acid, which is then converted to an alkali metal salt. The treated polymer is used in aqueous or aqueousalcoholic solution as a sizing agent. In the examples, polyacrolein is oxidized in NaOH solution, using as oxidizing agent, (1) CuO and O 2 , (2) CuO, Ag 2 O and O 2 , (3) O 2  and (4) Cu(NO 3 ) 2 .3H 2 O and O 2 .
