Title: Process for the production of shaped bodies from di-isocyanate-modified polyesters
IPC: C08G18/10
Filed: 1954-08-24
Abstract: In the process of the parent Specification in which an anhydrous linear aliphatic polyester is reacted with 20-100 per cent excess of a diisocyanate and the product reacted with a diamine in amount less than that equivalent to the free isocyanate groups in the modified polyester, the diisocyanate and diamine being so chosen that time is available for casting in the liquid state (tested by freedom from turbidity for at least 25 seconds in boiling methylene chloride), the diisocyanate and/or the diamine used has groups which react at different rates, whereby the reaction mixture remains castable for a longer period.  Suitable non-symmetrical reactants are 1,2,4-toluylene diisocyanate, hexhydrobenzidine diisocyanate, 1,2,4-toluylene diamine, 4 chloro-1,3-phenylene diamine and 2,6-dichloro-p-phenylene diamine. The polyester used need not be entirely aliphatic, up to 10 per cent non-aliphatic components being allowable in its preparation. In examples: (1) the reaction product from 140 gr. 1,2,4-toluylene diisocyanate and 1 kg. of a glycol adipic acid polyester is mixed with 54 gr. o-dichloro-benzidine at 130 DEG  C. The resulting melt remains castable for 8-9 minutes, whereas a melt using 1,2,6-toluylene diisocyanate remains castable for 1 1/2 minutes only.  After casting, the moulds are heated to 100 DEG  C. and the products removed after 10-15 minutes and after cured for 24 hours at 100 DEG  C; (2) as in (1) but using 39.3 gr. of 2.5 dichloro-1,4-phenylene diamine; (3) as in (1) but using 39.3 gr. of 2,6-dichloro-1,4-phenylene diamine; (4) 39.3 gr. 2,6-dichloro-1,4-phenylene diamine are mixed at 130 DEG  C. with the product from 200 gr. diphenylmethane diisocyanate and 1 kg. of a glycol adipic acid polyester and the melt cast and hardened.

Title: Improvements in cover plate assembly for sealing spaces between turbine blades
IPC: F01D5/30
Filed: 1963-06-20
Abstract: 1,012,066. Turbine rotors. GENERAL ELECTRIC CO. June 20, 1963 [July 11, 1962], No. 24670/63. Heading FIT. A turbine rotor disc has circumferentially spaced axially extending, fir-tree slots in the rim carrying long shanked blades, the roots of the blades having an axial length less than that of the slots to permit cover plates to fit into the slots with the blade roots, the plates blocking the spaces between the blade shanks. A turbine rotor disc 1, Fig. 1, carries in axial fir-tree slots 2 blades 3 having platforms 5, shanks 6 and roots 7. The axial length of roots 7 is less than that of slots 2, Fig. 6, so that segmental cover plates 8, also having fir-tree roots 9, may fit within the slots on either side of roots 7. Plates 8 comprise axially inner and outer plates, 15, 16 respectively, Fig. 3, which overlap at 15a, 16a to seal the spaces between shanks 6. Outer plates 16 carry lips 18 locating in a circumferential groove in blade platforms 5 but inner plates 15 terminate radially inwardly of platforms 5 at 17. Plates 15, 16 are notched at 11 to receive cylindrical pins 12 which lock platforms 5 together centrifugally. Roots 9 of plates 8 are retained axially by a strip 13 locating in a circumferential groove 1b in disc rim 1 and grooves 9b in roots 9. Pins 14 lock strip 13 in position. The construction reduces the effects of centrifugal bending moments resulting from axially offset cover plates. In a modification, the cover plates are identical and overlap consecutively.

Abstract: 387,740. Games. ANDREWS, J. D. F., The Lodge, Leysdown, Kent. Sept. 7, 1931, No. 25024. [Class 132 (ii).] Apparatus for playing a game comprises a base E on which the player stands and plays a ball with a club from a defined spot to one or other of a number of initial spots indicated by suitable marks such as labels H on rigid deflecting walls F surrounding the base, so that after one or more deflecting impacts the ball may proceed towards a defined goal, which may be one or other of devices A, B, C, or D for retaining the ball arranged at the corners of the board or elsewhere, or may be a suitable indicator, or merely a particular spot on the board, for example, the spot I. The direction of the shots may be indicated by lines on the board. Various combinations of shots to the same or different goals may constitute the game, and separate boards may be provided for different series of shots. The walls F may be of stone, concrete, wood, or metal, preferably steel, and the base E may be of wood, slate, concrete, or stone, or in a modification the floor itself may constitute the base. The initial striking-off spot or spots may be provided with a tee G of leather or the like with a depression in the centre in which the ball may rest. The retaining devices -may comprise a slightly inclined roof provided with a material such as indiarubber adapted to grip the ball or with spring-plate acting as a grip. In the form shown in Fig. 7, the ball J on entering the goal strikes against a tube O, causing a spring N which normally holds a tilting plate K in position against a block M, to tilt the plate until the ball is held bv a catch P thereon. In the form shown in Fig. 9, the ball J impinges against an arm R of the lever W, which is normally held in the unretaining position by means of a ribbon spring N which is mounted on a block M and is provided with a roller S pressing against a projection T on the lever W. The movement of the arm R causes the upper arm U of the lever to be lowered on to the ball, which is then retained by a projection P thereon. Indicators for denoting that the ball has struck an assigned spot may comprise a twoarmed lever pivoted to a block on the board, and so weighted at the end of one arm, that when the other arm is struck by the ball, the lever is caused to assume a new position.

Title: Production of pyrophosphates and polyphosphates
IPC: C01B25/42
Filed: 1953-09-15
Abstract: <PICT:0742623/III/1> Finely divided calcined orthophosphate is transported by hot gas through a long stationary pipe, the gas temperature, the length of the pipe and the flow velocity being such that conversion into pyro- or poly-phosphate takes place, preferably completely.  The production of tetrasodium pyrophosphate from disodium orthophosphate, sodium tripolyphosphate or a mixture of sodium tripolyphosphate and tetrasodium pyrophosphate from sodium orthophosphate, acid calcium pyrophosphate from monocalcium orthophosphate, neutral calcium pyrophosphate from dicalcium orthophosphate, and tetrapotassium pyrophosphate from dipotassium orthophosphate is mentioned.  Heated air, nitrogen or other inert gases, or combustion gases may be used and gas entering into chemical reaction with the starting or intermediate products may be used with the hot gas, examples being hydrochloric acid gas (to give with disodium orthophosphate, acid pyrophosphate), and oxidizing gases e.g. nitrogen oxides to destroy impurities in the starting product. If desired a part of the waste gas or a part of the finished product may be recycled.  Hot waste gases may be used to heat the reaction apparatus or, e.g. as the hot gas in a spray tower for producing the calcined orthophosphate.  To avoid sintering, a pipe is used of which the first part is wider than the rest, whereby sintering and caking take place before the particles touch the wall of the pipe.  In the Example, disodium orthophosphate the majority of which has a particle size of less than 150 microns, is fed through worm 1 (see Figure), into a pipe 14.5 m. long and having a diameter of 100 m., and heated by means of illuminating gas burnt in burners B1, B2 and B3 whereby temperatures ranging between 250 DEG C. at t2 and 195 DEG C. at t3 and 370 DEG C. at t9 are obtained in the pipe.  The flow velocity is about 5 m/sec.  The resultant tetrasodium pyrophosphate is removed by cyclone separator 2, the gases are metered through gas flow indicator 3 and pass through a throttle valve 4 before being extracted by fan 5.  If desired the diameter of the pipe could vary along its length so as to maintain the gas velocity constant.

Filed: 1924-10-28
Abstract: 233,651. Owens Bottle Co. (Assignees of Cramer, A. N.). May 9, 1924, [Convention date]. Blowing. - Relates to a machine of the kind in which the parison mould is charged in an inverted position, the metal being delivered into the open end of the mould. According to the invention, the end of the mould is closed, after the charge has been dropped in, by a plug which reduces the space within the mould, so that excessive blowing-up of the charge when forming the parison is prevented. The device is shown applied to a machine in which a charge 19 is dropped into a mould 12 through a funnel which is then moved and a blowhead brought over the mould. The blowhead comprises a cylinder 21 containing a piston 22 having an extension' 23 to which a plug 24 is attached. The plug is adapted to enter the upper end 25 of the parison mould cavity and thus reduce the space above the charge 19. An annular piston 27 surrounds the extension 23, and is provided with an extended sleeve 28 that forms a telescoping connection with the cylinder 21. In operation, air is admitted by a pipe 29 to the space between; the pistons 22 and 27. The piston 27 is moved downwards until the sleeve 28 rests on the mould, and the air then passes through passages 31 in the extension 23 and packs the charge of metal into the mould. Air is next admitted by a pipe 33 above the piston 22, thus causing the piston to move downwards and the plug 24 to enter and close the mould cavity. The charge of metal is then blown up by air admitted through the ring mould around the plunger.
