Patent GB-578635-A (GB)
Title: Preparation of amino alcohols
IPC: C07C215/08
Filed: 1944-01-19
Abstract: Amino alcohols are prepared by reacting an a -b -unsaturated ketone with ammonia under non-hydrogenating conditions at a temperature not substantially above 100 DEG  C. whereby it is converted to the amino ketone and hydrogenating this in the presence of a mild hydrogenating catalyst to the corresponding amino alcohol.  The hydrogenation may be carried out at a temperature below 250 DEG  C. under pressure and the catalyst is copper, pyrophoric nickel, zinc oxide, chromium oxide, manganese oxide or the noble metals or their oxides.  Suitable unsaturated ketones are mesityl oxide, homomesityl oxide, 3-methyl-pentene-2-one-4 and the 7 carbon atom unsaturated ketones from the dehydration of the condensation product of acetone and methyl ethyl ketone.  In the examples, mesityl oxide is reacted with aqueous or anhydrous ammonia and the product hydrogenated in the presence of a Raney nickel catalyst to give diacetone alkamine. Salts of diacetone alkamines with such fatty acids as stearic, oleic, caprylic nonylic, capric, undecylic, lauric, tridecoic, myristic, pentadecoic, palmitic, margaric, nondecoic, arachidic, henecosoic, behenic, tricosoic, lignoceric, pentacosoic, cerotic, carbocenic, octacosoic, montanic, melissic, myricinic, psyllaic and psyllostearic have wetting, emulsifying and related properties.

Title: Improved method of treating cast iron and castings obtained thereby
Filed: 1953-01-16
Abstract: White cast iron containing 0.7-3.0 per cent copper is heat-treated by heating to a temperature above that of the end of the eutectoid reaction and quenched, heated to cause the formation nuclei to a temperature between 400 DEG  and 500 DEG  C., and graphitized by heating to a temperature above that of the end of the eutectoid reaction.  The cast iron may be heated to 900 DEG C., quenched at 180 DEG C. for one minute and cooled in still air, heated to 450 DEG  C for 1-24 hours, cooled in air and finally heated to 875 DEG C. for 1/2 to 24 hours to produce nodular graphite.  The cooling after heating to 450 DEG CC. may be omitted.  The cast iron may be quenched at 450 DEG  C. from the initial heating.  The following alloying elements may be added: 0.2 per cent Cr, 0.15 per cent Mo, 0.03-0.05 per cent Ti, or 0.12 per cent Zr, or the Mn content may be increased by 0.15 per cent.

Title: Circuit for the synchronous control of step-by-step switch devices
IPC: H04Q9/04
Filed: 1952-01-22
Abstract: 706,880. Electric selective signalling. LICENTIA PATENT - VERWALTUNGS GES. Jan. 22, 1952 [Jan. 22, 1951], No. 1813/52. Class 40 (1). One control line. only is used between two synchronously controlled step-by-step switching devices, reciprocal control being effected by an increase in the line current effected at one end and a brief interruption of the line current effected at the other end. As shown a relay chain I, II, III .... at station B is advanced synchronously with an electromagnetic step-bystep switch at station A, the switch drive magnet D only being shown. The manner of starting, stopping and zeroizing the switches is not shown. When the drive magnet D is deenergized the high resistance winding J1 of a relay J at station A is energized over the line SL in series with relays O, S1 and the forward winding I<SP>1</SP> of a self-locking relay I (assuming the relay chain at zero position). Relay J only operates in this circuit and energizes the drive magnet D which steps the associated switch and operates a contact d to switch the low resistance winding JII of relay J into line in lieu of JI to increase the line current. This change over is effected without de-energizing J by providing a condenser C the discharging current of which holds the relay J up during the change over. The increase in line current operates relays S1, I, O in the order mentioned. Relay O locks by means of a holding circuit, not shown, and opens the line circuit at o', so that relays S1, J fall off. Relay J releases the stepping magnet D, which switches the high resistance winding J1 back into the line circuit which is completed as S falls off through the reverse winding I" of relay I, the forward winding II' of the second self-locking relay II in the chain I, II, III, .... and a relay S2. As before, J, only, operates in this circuit, to advance the associated stepping switch and increase the line current, whereupon S2 and then II<SP>1</SP>, I" operate in turn. The winding II<SP>1</SP> prepares at contacts 2' the circuit for the forward winding III of relay III, after which winding I" resets the relay I and opens the line circuit at 1<SP>1</SP> to initiate the next step at station A. The relays I, II, III ... are thus operated in succession in step with successive positions of the switch D.

Abstract: 494,741. Insulators, BUSHING CO., Ltd. Jan. 22, 1937, No. 1905. Void. Convention date, Jan. 23, 1936. [Class 36] An insulator, more particularly a lead-in bushing of the condenser type, comprises a wound tubular insulating body having a member inserted within or surrounding it so as to leave a clearance space adjacent its inner or outer periphery and having a substance capable of hardening introduced into the clearance space and allowed to harden therein under pressure. The Figure shows an insulator comprising two coaxial wound tubular bodies 8, 10 with a space 12 between them. The inner body, which has conducting inserts 9, is wound on a mandrel 7 which may serve as the lead-in conductor. The outer body is contained in an insulating tube 11. The space 12 is filled with a substance which is allowed to harden therein under pressure, the filling being effected by clamping, with the interposition of packing 13, the ends of the two bodies between plates 14, 15, exhausting the space 12 through a pipe 16 in the plate 14, then introducing the filling substance in liquid form through a tube 17 in the plate 15 and maintaining the filling under pressure until it has set. In a modified construction the clearance space is provided between the inner periphery of the tubular body and a core loosely mounted in its central opening. The filling material, which is preferably an insulating cement, may be a thermoplastic resin which is introduced by heating and allowed to harden by cooling ; or the material may be a compound which hardens by chemical reaction, such as a phenol aldehyde resin to which hydrochloric acid is added just prior to its introduction into the clearance space. When the tubular insulating body is such as to require a heat treatment after winding, a heat hardening resin is preferably used as the filling material so that the heat treatment and the hardening of the filling material may occur simultaneously.

Abstract: 584,829. Lubricating valves. BRIGGS MANUFACTURING CO. Jan. 26, 1945, No. 2097. Convention date, March 20, 1944. [Classes 7 (ii) and 7 (vi)] Lubricant is supplied to the surface of frustoconical rotary valve 33 through a conduit containing a plug which restricts the flow of oil to the valve and which is arranged opposite the sparking plug 37. The combustion chamber 34 is formed in the valve 33 which is mounted in the cylinder head. An annular relief 44 formed wholly in the valve or its seating or partly in both extends for the full height of the valve port ,35. Lubricating oil is supplied under pressure through passages 47, 47a, 45, 49 in the, head opposite the sparking plug 37 to a duct 50 containing a plug 51 past or through which oil is supplied to the valve 35 beneath the relief 44. The remaining oil escapes through passages 52, 54 to a reservoir 55 in the head. Oil flows through the duct 50 on the valve through the clearance between the plug 51 and the duct or through grooves in the plug. The plug 51 is held against the valve by the pressure of the lubricating oil and the'valve 33 has, a flattened portion 56 to enable the plug 51 to be reciprocated in the duct 50. A second duct 57 containing a plug 58 conveys oil to the valve surface above the relief 44. The outlet orifice 47b leading to the reservoir 55 may be smaller than the inlet orifice 47a to the passage 45 to increase the oil pressure around the plugs 51, 56. In a modified construction the duct 50 is closed or partly closed by a plug of sintered metal through which oil seeps on to the valve. Additional oil may be supplied by providing grooves in the plug. The cylinder and head are provided with' communicating water jackets 28, 25 and leakage is prevented by sealing rings 29, 29a. The lower end of the valve. housing is formed with an annular groove to receive a ring 31 of metal which causes the adjacent portion of the valve housing 30 to expand at the same rate as the rotary valve.
