Title: Particulate transfer control device
IPC: B65G53/66
Filed: 1975-04-17
Abstract: 1499594 Blasting FRUEHAUF CORP 17 April 1975 [15 May 1974] 15935/75 Heading B3D [Also in Divisions B8 and F2] A control device for use with apparatus, such as abrasive blasting apparatus, for pneumatically transferring a particulate material having an air passageway 12 and a particulate passageway 14 communicating with the air passageway, the device comprising closure means 42 for the air passageway, closure means 46 for the particulate passageway, and a sequencing mechanism connected to the closure means 42 and 46 and having control fluid passageways, the mechanism being so arranged that a first flow pattern of the control fluid when both closure means are open acts on the closure means first to close the particulate passageway and then the air passageway. As described, the apparatus is for abrasive blasting and a compressed air source is connected to an inlet 18, particulate material, such as sand is supplied to the passageway 14, and a hose having a nozzle is connected to an outlet 24. A transverse section 28 in the passageway 12 registers with a bore 36 which can be closed by the closure member 42, which is in the form of a diaphragm, when air pressure is supplied to a space 38. The particulate passage 14 communicate with the passageway 12 and can be closed when air pressure acts in a space 66 to cause a piston 61 to compress a resilient annulus 46. The sequencing mechanism consists of a housing 78 on the diaphragm housing connected by a pipe 80 to a control valve 82 and a source of control fluid. The pipe 80 connects with a bore 88 having a one-way valve 92 controlling a passage 90 leading to the space 38. A bore 86 leading from bore 88 is connected by bleed holes 94, 102 with the space 38 and a bore 100, respectively, bore 100 being connected by a pipe 84 to the space 66, and a one-way valve 96 connects the bore 100 to a passage 98 leading to the bore 86. With the valve 82 in the position shown, both spaces 38 and 66 are vented to atmosphere and both closure means are open, air and saud thus being supported on the nozzle. When valve 82 is moved by a handle to the dotted position, the control fluid is connected to bore 88. The control fluid, because the ball valve 92 closes, passes along bore 86, past ball valve 96 into bore 100 and pipe 84 to act quickly in space 66 to cause the piston to compress the member 46 and close the particulate passage 14. The control fluid also slowly passes through bleed passage 94 into space 38 so that the diaphragm eventually closes the bore 36 and thus the air passageway 12. To re-open the passageways, the valve 82 is turned to its position shown solid and the ball valve 92 permits the space 38 to be quickly relieved of pressure so that the diaphragm opens the bore 36 and thus the air passageway 12, the ball valve 96 closing so that the space 66 is vented through the bleed hole 102 and passages 86, 88 to cause the piston to gradually relieve the pressure on the member 46 and open the particulate passageway 14 after the opening of the air passageway 12.

Abstract: Spheroidal graphite is produced in apparatus comprising a melting unit, one or more ladles, means for rotating a ladle rapidly in alternate directions, and an immersion bell for adding the spheroidizing agent.  An oxygen lance may also be provided. In operation a ladle of iron is first desulphurized with reagents such as sodium carbonate or calcium carbide on the rotating device; after which slag is removed; the iron is then if necessary blown with oxygen to reduce its carbon content, after which spheroidizing additions are made.  The iron may be centrifuged and allowed to decelerate slowly after desulphurizing and/or at the conclusion of the process, whereby effective degassing is obtained.

[Also in Division B5] A device for dispensing predetermined amounts of plastic material such as for use in lining bottle caps, comprises one or more discharge passages 40 through which the material flows, one or more blades 42 being arranged to be rotated across the exit ends of the passages in order to dispense predetermined quantitites of material. The plastic material is fed through a main feed passage 44 formed in a block 38, and into a bore 56 in which a plunger 54 reciprocates; the passage 40 leads from the bore and communicates with a discharge nozzle 114. The nozzle passes through a block 136 in which passages (148, 150, 154, 156, Fig. 7) are provided for a cooling fluid; a pair of identical nozzles are located in the block for co-operation with a pair of blades 42.

Title: A process for reversing the rotation of optically active phenyl alkamines
IPC: C07C215/30
Filed: 1933-06-09
Abstract: The rotation of optically-active phenylalkamines of the formula:-- <FORM:0405520/IV/1> wherein R1 represents phenyl or a monohydroxyphenyl and R2 and R3 an alkyl group or hydrogen, is reversed by first acylating and then splitting off the acyl group. In the case of compounds containing two asymmetric carbon atoms, the effect of the treatment is to give the opposite antipode of the other pair of stereoisomers.  According to the examples: (1) d-m-hydroxyphenylethanol - N - methylamine, obtained by resolving the racemic base with d-tartaric acid, is acetylated with acetic anhydride and then treated with dilute sulphuric acid to split off the acetyl group, yielding the l-compound; (2) l-ephedrine is subjected to the process of (1) and is thereby converted into d-pseudo-ephedrine; (3) d-o-hydroxyphenylethanol-N-methylamine, prepared by resolving with ammonium d-bromcamphor sulphonate the racemic compound obtained by the process of Specification 354,226 for the corresponding m-and p-compounds, is transformed into the corresponding l-compound by treatment with benzoyl chloride, followed by saponification with dilute hydrochloric acid; (4) d-pseudo-ephedrine is converted into l-ephedrine by acetylation with acetic anhydride and subsequent saponification with dilute sulphuric acid.

Abstract: 382,955. Safety-razor blades. WEBBERLEY, D. J., 33, Lowther Hill, London. June 8, 1931, No. 16660. [Class 30.] A safety-razor blade of the kind having a central perforated design in the form of letters a, words, &c., has additional slots c to enable the blade to fit holders other than those designed with projections to fit only the main design, and the slots c break into the main design through an opening d narrower than the main slots and than the minimum thickness of any holder projection b, so as to effect a wedging action and prevent movement of the blade on the holder. The slots c, which may be of varying width and engage projections of varying thickness, may be in the form of a design similar to or different from the main one. The narrow openings d prevent the projections of one design slipping into the slots of another. The invention may be applied to the blade described in Specification 360,860. The Provisional Specification states also that the design may be stamped, die-cast or hot pressed.
