Abstract: 600,019. Turbines and compressors. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., aud FEILDEN, G. B. R. Jan. 16, 1945, No. 1353. [Classes 110 (i) and 110 (iii)] The outer bladed structure of an axial flow compressor, turbine or the like comprises a circular section hollow casing containing at least one blade-supporting ring, which may be of unitary or segmental construction, having on its radially outer surface annular axiallyspaced ribs which engage corresponding seatings in the casing and on its radially inner surface a shallow annular groove in which the blade platforms of the radially inwardly extending blades are seated. The stator blades of a turbine or compressor 3 formed with integral shallow root platforms 4 are seated in grooves in rings 5 which have external peripheral ribs 6 which co-operate with raised seating surfaces on the inside of the casing 2 to define cavities 7. The cavities 7 serve to accommodate the heads of the rivets 8 attaching the blades 3 to the rings 5 and may also be used as passages for the cooling fluid. The rings 5 which are attached to the casing by bolts 9 may support any number of rings of blades and may be formed of two or more peripheral segments and the number of attaching bolts may be reduced by forming the ends of the rings 5 with interengaging stepped flanges 10. The depth of the grooves in the rings 5 is such that the platforms 4 do not project above the surrounding surface of the rings. In a modification, only alternate blades are attached to the blade-supporting ring, the intervening blades are supported by means of interengaging flanges on the blade platforms. , The thickness of the platforms for the blades attached to the ring is less than that for the intervening blades so that the latter are firmly clamped to the casing.

Abstract: 1,146,553. Graft polymers modified with polyamides. FOSTER GRANT CO. Inc. 11 Jan., 1967, No. 1627/67. Headings C3G and C3R. A thermoplastic, fibre-forming graft polymer is derived from (i) a first graft copolymer, which comprises a monovinyl (including monovinylidene) aromatic compound grafted on to an unsaturated hydrocarbon polymer having a weight average molecular weight of from 500 to 50,000, the macromolecular backbone chain of the unsaturated hydrocarbon polymer having two or more carboxyl groups attached thereto, at least one of which is an end group, and (ii) lactam having at least six atoms in the lactam ring, wherein the fibre-forming graft polymer contains from 5 to 50 weight per cent of the monovinyl aromatic compound based on the total amount of the lactam incorporated in the fibre-forming polymer, the combined weight of the monovinyl aromatic compound and the lactam being in the range of from 95À0 to 99À9% by weight of the total weight of the fibreforming graft copolymer. The unsaturated hydrocarbon polymer is preferably derived from a C 4  to C 6 -diene. The lactam, e.g. caprolactam, 2-oxo-pentamethyleneimine, 2 - oxo -heptameth - yleneimine, 2-oxo-octamethyleneimine or 2- oxo-decamethyleneimine may be reacted with the first graft polymer in the presence of a catalyst comprising water, an organic compound which liberates water under the reaction conditions, or aminocaproic acid. The examples illustrate a process in which (i) styrene is grafted on to a liquid polybutadiene having a carboxyl group at each end of the polymer molecule in the presence of tert.-butyl peracetate and molten caprolactam to form the first graft polymer and (ii) the temperature of the reaction mixture is raised, additional caprolactam and water are added and reaction carried out to yield the fibre-forming graft polymer. This process is modified (a) by partly replacing the styrene with alpha-methylstyrene or wholly replacing it with a mixture of o- and p-chloro. styrenes, or with p-methylstyrene or (b) by replacing the caprolactam with caprylactam or dodecalactam.

Title: Improvements in and relating to the moulding of hollow bodies, such as pipes, from apasty material
IPC: B28B21/48
Filed: 1940-01-29
Abstract: 541,520. Moulding hollow bodies. SALVANESCHI, P. Jan. 29, 1940, No. 1786. Convention date, Feb. 18, 1939. [Class 87 (ii)] Hollow bodies, for example pipes, are made by delivering pasty material, which may contain fibres, by means of a vibrating table with a rotating drum which is spaced therefrom and serves as a forming core for the hollow body. Paste from a hopper 12 flows from an opening 13 along a table 4 provided with 'sides 19 and which is pivoted on an eccentric 10 and reciprocated in the direction A-B and B-A by rotation from shaft 7 through an eccentric 8 and link 6, and a rotating drum 1. Rotation of a shaft 11 on which is fixed an eccentric 10 causes the side of the table to move away from the drum in the direction D-C as the pipe is formed. If further pressure is required to compress the pipe, shaft 11 is further rotated to move the end of the table in the direction C-D. A suitable forming drum comprises a permeable body 1, Fig. 3, and a flanged head 16 over which fits a permeable sleeve 18 for forming the pipe socket. Water permeating through the drum is discharged through openings 13, radial holes 14 and longitudinal hole 15. The profile of the table follows the profile of the drum, and a plurality of tables may be used simultaneously or in succession. Reduced pressure may be maintained inside in the porous drum which may also be provided internally with warming, cooling or wetting means. The nature of the vibrations imparted to the table may be varied by varying the relative speeds of rotation of shafts 7 and 11. The hopper 12 may be replaced by a balanced overflow hopper. The gap between the table and the drum may be automatically varied.

Abstract: 157,981. Schultz, E. Jan. 20, 1920, [Convention date]. Spring wheels with continuous outer rigid ring and pneumatic and helical spring cushions.-A spring wheel comprises a tread ring guided between the inturned rim rim portions of side discs connected to the hub, the tread ring and rim portions having internal curved recesses forming thrust surfaces for radially-arranged arms supporting on cushioning- devices. In the construction shown in Figs. 1 and 2, a continuous pneumatic tube 2 carried on a floating rim 1 is fitted with a cover 4 having side bosses 5 and central ribs 11 which engage curved seatings 6, 12 formed respectively on the inturned flanges 7 of the discs 8 and on the tread ring 13. In the modification shown in Figs. 3 and 4, the pneumatic'cushion is formed by a series of cylinders 21 carried on a flexible or other ring 23 and fitted with hollow pistons 22 having parts 28, 29 engaging the tread ring and disc flanges. The cylinders 21 are connected to a common supply-pipe 32 fitted with an inflating-valve 35. Each cylinder may also be fitted with a non-return ball-valve so as to be automatically charged in use. As shown in Fig. 3, helical springs 44 may be fitted in the cylinders to take the normal load, excessive shocks being taken by the compressed air. In a further modification, the cylinders are formed integral with a ring having communicating passages. In all cases, the bearing-surfaces on the rim flanges are preferably formed of fibre &c. packing-rings.

Abstract: 959,589. Expiratory valves for oxygen masks. BEAGLE-AUSTER AIRCRAFT Ltd. April 4, 1962 [Jan. 16, 1961], No. 1810/61. Heading A5T. [Also in Division G3] A compensated expiratory valve for an oxygen mask includes a valve body 11 having a partition wall 16 dividing a compensating pressure compartment 18 from the rest of the valve, a resiliently mounted primary diaphragm 14 connecting the orifice 21 of the mask with primary exhaust ports 22, an inlet 19 situated between the wall 16 and the diaphragm 14 to admit oxygen to the compartment 18, a secondary diaphragm 23 resiliently mounted in a chamber 25 to actuate a mushroom valve 30 which opens and closes ports 31 in the wall 16 which connect the compartment 18 with secondary exhaust ports 26, there being a bleed-hole 28 in the valve body 11 on the/or side of the diaphragm 23. The diaphragms operate against light springs 20 and 32. In the event of rapid reduction of pressure in the pressurized cabin of an aircraft in which the mask is used, the pressure in the chamber 25 will fall faster than that in the compartment 27 so that the mushroom valve 30 will open and vent pressure from the compartment 18 through the ports 26. This will, in turn, allow the diaphragm 14 to open for a period and allow air to be vented from the wearer's lungs to equalize with the external pressure drop. Fig. 2 (not shown), illustrates an embodiment in which the diaphragm 14 is constructed in two parts with a spring between them so that the diaphragm 14 does not open in the event of a failure of the oxygen supply.
