Title: Improvements in or relating to emulsifiable oil composition
IPC: C10M173/00
Filed: 1953-03-17
Abstract: An emulsifiable oil composition suitable for use as a soluble cutting oil in metal-working operations comprises a major proportion of a lubricating oil and a minor proportion of the spent aqueous residue obtained from the treatment of a naphthenic mineral lubricating oil with an aqueous solution of an alkali metal aromatic sulphonate and sodium hydroxide.  The lubricating oil employed in the emulsifiable oil composition may be a mineral lubricating oil, but synthetic lubricating oils such as diesters, complex esters or synthetic hydrocarbon oils may form a part of, or the whole of, the lubricating oil.  The aqueous solution mentioned above is known as "Napex" and may contain such alkali metal aromatic sulphonates as sodium xylene and/or toluene sulphonates.  The spent "Napex" is a heavy sludge containing a relatively large proportion of naphthenates and some of the sulphonates.  The emulsifiable oil composition may contain additional ingredients such as oil-soluble petroleum sulphonates (e.g. sodium petroleum sulphonates), other soaps (e.g. sodium or potassium rosinates), non-ionic emulsifiers (e.g. partial esters of polycarboxylic acids), fatty acids (e.g. oleic acid), triethanolamine, aliphatic alcohols (e.g. diethylene glycol or isopropyl alcohol), rust inhibitors (e.g. phosphates or chromates), extreme pressure agents and oiliness agents.  A small amount of water added to the composition aids emulsification.

Title: Improvements in or relating to die sets for crimping electrical connector ferrules onto electrical conductors
IPC: H01R43/058
Filed: 1961-03-02
Abstract: 907,370. Jointing by stamping. AMP Inc. March 2, 1961 [March 9, I960], No. 7638/61. Class 83 (4). A crimping die set for the confined crimping of an electrical connector ferrule on to an electrical conductor includes a crimping die having a crimping recess and a crimping anvil for insertion into the recess to crimp an electrical ferrule on to an electrical conductor therein, the side edges of the crimping face of the anvil being relatively displaceable to abut the side walls of the recess to prevent extrusion of the ferrule material between each edge and the side wall adjacent thereto during crimping. In an embodiment the crimping die 2, Fig. 5, co-operates with an anvil 13<SP>1</SP> having a central longitudinal slot 14 which provides a pair of diverging fingers 15 the ends of which have arcuate crimping surfaces 16. When the anvil enters the die 2 the edges 18 of the fingers abut the walls 6 of the die prior to the application of compressive force to a ferrule 10 and an electrical conductor 12 disposed in the die recess. Extrusion of the ferrule between the edges 18 of the fingers and the die wall is prevented but slight extrusion takes place into the slots 14 of the anvil thus providing a rib 10<SP>1</SP> on the outer surface of the ferrule, Fig. 7. In another embodiment the slot 14<SP>1</SP>, Fig. 9, in the anvil has parallel walls 17<SP>1</SP> and the side edges 18 of the anvil crimping face do not engage the walls 6 of the die. When the ferrule 10 is compressed by the fingers compressive forces urge the fingers apart and into engagement with the die walls to prevent extrusion between the finger edges and the die wall. The fingers may be spring-loaded away from one another in the first embodiment and towards one another in the second embodiment. The anvil may have two slots providing three fingers the centre finger remaining stationary during the crimping operation.

Title: Electric long-distance indicating systems
IPC: H04L12/18
Filed: 1930-07-12
Abstract: 365,128. Electric signalling systems. SCHEIDEGGER, H., 3A, H ohenzollernstrasse, Wannsee, near Berlin. July 12, 1930, No. 8034. [Class 40 (i).] In a system for transmitting indications comprising a number of digits to one of a plurality of groups of indicators, when a group of indicators is selected, a relay individual to that group is operated which completes circuits for restoring the indicators selected to normal, and circuits for the new indications to be received, and allows the selector to be freed for use on a succeeding transmission. An indication is given at the control point when the indicators are normal so that keying may take place. Several similar indicator boards may be controlled from a single control station, and groups of indicators may be restored to normal simultaneously if required. As described several indicator boards m are connected over cables f and junction box g to a keyset h. The indicator boards comprise groups of indicators m1, m2 each consisting of four changeable indications. If the designation on m2 is to be changed key T5 is depressed a number of times to move indicator SK into position 2. Key T5 completes a circuit over l1 for relays SK, A and T in series, relay SK controlling the indicator SK and relay A controlling selector W through DW and ratchet q. T holds up during the impulse train, energizing II and III. When T falls the relav Y associated with indication m2 energizes and relay II releases but during the slow period of III, relay IV pulls up, so that, with Y operated, IV holds over its winding (I) in series with interrupter Ub and off normal contacts n1.. n4 of indicators p1..p4. The magnets Z1..Z4 are energized in this circuit and step the indicators to normal. When all the indicators are in their zero positions, relay IV releases and the circuit is completed over l6 for KR which controls lamp KL. The new indication is set up by keys T1.. T4, the keys controlling indicators p1..p4 respectively through relays B.. E. Y holds during the impulse trains over its winding (II) in series with R. Relay R completes a circuit for R1 which removes the short across X to prevent another Y relay being operated before the transmission in progress is completed. The relays Y are all provided with special windings (III) which are connected in parallel to a special contact of the selector W. When this contact is selected all the Y relays connected thereto are energized and their respective indicator groups are all restored to zero.

Patent GB-569182-A (GB)
Title: Manufacture of polymeric materials
IPC: C08F214/08
Filed: 1941-06-30
Abstract: Polymeric materials are prepared by interpolymerizing a mixture of asymmetrical dichloroethylene with an a -methylene aliphatic mononitrile having the formula <FORM:0569182/IV/1> wherein R is hydrogen, halogen, an alkyl group having from one to four carbon atoms, or an aryl group, the nitrile comprising 5 to 50 per cent of the combined weight of the two monomers.  The interpolymerization may be effected in an acidic aqueous medium containing an emulsifying or dispersing agent and an oxygen-liberating polymerization catalyst; the emulsion may comprise a mixture of the monomers, or initially may comprise only one of the monomers, the other being added as polymerization proceeds.  Alternatively, (1) the process may be carried out in a solvent for the monomers and a non-solvent for the interpolymer, or in a solvent for both the monomers and the interpolymer; (2) the monomers may be interpolymerized in bulk without an added diluent, the product being then dissolved in a solvent such as an aromatic or chlorinated hydrocarbon, a ketone or ester, or dioxan, and precipitated by the addition of a non-solvent such as water, methanol, ethanol or aliphatic hydrocarbons; (3) the product may be obtained in granular form by agitating and heating under reflux a mixture of the monomers containing the catalyst with an aqueous solution containing a protective colloid; (4) the process may be effected under pressure, e.g. of nitrogen or carbon dioxide; (5) the process may be continuous.  Suitable catalysts are hydrogen peroxide, perborates, persulphates, peracetates, peracetic acid, and benzoyl, acetyl benzoyl, dibutyryl, lauroyl and succinyl peroxides, and suitable dispersing agents for use in acid media in the emulsion process are salts of true sulphonic acids such as alkyl naphthalene sulphonic acid and salts of acid sulphuric esters of long chain compounds, e.g. the sodium salt of acetoxyoctadecane sulphate.  The thermal decomposition of the interpolymers may be minimized by the addition of stabilizing agents such as described in Specification 525,048.  The interpolymers may be mixed with, or prepared in the presence of plasticizers, heat stabilizers, fillers, pigments, dyes, or natural or synthetic resins, and may be used in the preparation of plastics, fibres, films, adhesives and coatings.  In examples: (1) and (2) asymmetrical dichloroethylene and methacrylonitrile are heated in the presence of benzoyl peroxide and acetic anhydride; and (3), (4) and (5) asymmetrical dichloroethylene and methacrylo or acrylonitrile are emulsified in water containing hydrochloric acid and the sodium salt of acetoxyoctadecane sulphate and heated in a closed vessel.  Interpolymers of asymmetrical dichloroethylene with a -methacrylonitrile disclosed in Specification 525,048 are referred to.
