Title: Alloys having improved machinability
IPC: C22C19/00
Filed: 1962-01-02
Abstract: Iron, nickel and cobalt alloys have dispersed throughout them 0.1-1% of boron mononitride to confer improved machinability. The nitride may be added as a preformed solid to the molten alloy or boron and nitrogen may be added separately, e.g. as master alloys such as ferro-boron and nitrogenous ferro-chromium. In the latter case, the cast alloys must be heated at 1700-2300  DEG F., e.g. for 8 hours, to precipitate the nitride; it may also be necessary to carry out the melting under an atmosphere of nitrogen.  Particular ranges of composition which may be treated are given as: (a) austenitic stainless steels containing .C.- 0.25% .Mn.- 8% .Si.- 3% .Cr.-26% .Ni.6-46% .Fe.balance .Nb, Ti, Mo, Cu, S, P, Se. .and excess N may also be present..

Title: Audio signal transmission method
Inventor: SCHROEDER ERNST DIPL-ING
IPC: G10L19/035
Filed: 1996-01-18
Abstract: The invention relates to the digital transmission of an audio signal. To save transmission and/or storage capacity, the digital signal is converted into a signal representing the short-time spectrum before the transmission and components of this signal are processed on the basis of psycho-acoustic rules, components of this signal below predetermined thresholds not being taken into consideration. 
<??>It has been found that the general not taking into consideration can lead to reductions in quality in particular signals. 
<??>The invention provides a remedy for this in that at least a first threshold is defined below which only amplitude values outside of psycho-acoustically distinguishable frequency ranges are not taken into consideration.

Title: Means for the removal of air from finely divided material before consolidation underpressure
IPC: B30B15/00
Filed: 1949-01-06
Abstract: 669,835. Compression-moulding of finelydivided materials. CLARK, F. H., and LEES, C: A. Jan. 3, 1950 [Jan. 6, 1949], No. 361/49. Class 87(ii) In a press for consolidating finely-divided material in a mould by means of a vertically-reciprocating ram, in which before the material in the mould is consolidated the space around the mould is sealed off from the atmosphere and the air is sucked by vacuum from the material in the mould, valves for connecting the space to vacuum and valves for connecting the space to atmosphere are provided, these valves working in synchronism with the reciprocating movements of the ram. The drawings show a screw-press for making tiles, comprising a fixed mould 45 having a tileejecting bottom die 46, and a main ram 10 having a pressing die 14. The die 14 is fixed to a head 15 on the lower end of a secondary ram 12 fixed in the main ram 10. The main ram is vertically reciprocated by a spindle 11 the upper part of which is screw-threaded. A sleeve 16 is slidably mounted on the ram 12 and has a flange 17 to which is fixed a hollow box-like member 42 having a rubber sealing member 44 which, when the rams descend, makes an air-tight joint with the upper face of mould 45. The space within the box 42 is connected to vacuum by means of passages 22 in head 15, bore 23 in ram 12, bores 24 in ram 10, passage 26 in a head 25 fixed on ram 10, valve 27 and vacuum pipe 28. Fig. 2 shows valve 27 in its closed position, the valve being held closed by a spring 29. To open the valve a frame 33, fulcrummed on pins 34 in head 25 and connected by adjustable rods 31 to the valve stem, must be rocked counter-clockwise, and this is done, as the rams descend, by engagement of rollers 35 on the frame with cam surfaces 36 on the upper ends of rods 37 fixed at their lower ends to flange 17. Gravityclosed valves 51 for connecting the box space to atmosphere are mounted in flange 17. Operation.-With the press in the idle position shown, vacuum valve 27 is closed and atmospheric valves 41 are open, the latter being held open by engagement of their stems with head 15. The rams descend and the box seats on the mould. Descent of sleeve 16, flange 17 and rods 37 is thus halted, but rams 10, 12 continue their descent against springs 40 surrounding rods 37. When head 15 leaves flange 17, valves 41 close, and when rollers 35 abut cam surfaces 36, valve 27 opens. When the rams ascend the reverse movements occur. The bottom die spindle 48 extends through a sealing bush 49. A machine for making bricks is described, Fig. 5 (not shown), in which the ram dwells just before the die enters the mould, to give time for the vacuum to build up in the box, and in which lubricating oil is fed to the ram. According to the Provisional Specification the upper die may be heated by steam or electricity.

Title: Improvements in or relating to production of nitric acid esters of higher alcohols and glycols
Inventor: LANE EDWARD SYDNEY
IPC: C07C203/04
Filed: 1951-01-08
Abstract: In a method of producing nitric acid esters of alcohols or glycols having at least nine carbon atoms in the molecule the crude nitration reaction product resulting from the esterification of the alcohol or glycol is leached with methanol to remove contaminating substances arising from side reactions and/or unreacted alcohol or glycol.  In methods of producing nitric acid esters of higher alcohols or glycols (a) an alcohol or glycol having at least nine carbon atoms in the molecule is esterified with fuming nitric acid and the resulting reaction product is leached with one or more quantities of methanol to remove contaminating substances; (b) the alcohol or glycol is esterified by means of fuming nitric acid in the presence of acetic anhydride, initially maintained at a low temperature up to about 10 DEG  C. and then allowed to warm up, the reaction product is treated with water, the aqueous phase resulting is removed and the remaining reaction product is leached with methanol or (c) fuming nitric acid is added to a substantially equimolecular amount of acetic anhydride and while the temperature of the mixture is controlled at substantially 5 DEG  to 10 DEG  C. the higher alcohol or glycol is slowly added whilst the reaction mixture is agitated, the temperature is allowed to rise, water is added and the resulting organic phase containing the reaction product is separated and leached with an amount of methanol approximating to one-tenth or more of the volume of the organic phase by agitating the two together, the methanol layer is removed and the leaching is repeated with a further small quantity of methanol.  Nitric acid esters of higher alcohol and glycols prepared by other esterification methods, e.g. by the action of nitric and sulphuric acids on the cooled alcohol or glycol in the presence of urea, may be purified in a similar manner.  In examples: lauryl nitrate is prepared by dropping lauryl alcohol and nitric acid into acetic anhydride, diluting the reacted mixture with water, removing the aqueous layer and extracting the residue with portions of methyl alcohol (1); cetyl nitrate and decamethylene nitrate are similarly prepared (2) and (3).  The esters prepared according to the examples may be converted into the corresponding alkyl pyridinium nitrates or alkylene bis pyridinium nitrate, e.g. by refluxing with the appropriate amount of pyridine, diluting with acetone, decolourizing the extract and evaporating off volatile material in vacuo.  Methanol may be added to reduce the refluxing temperature.
