Title: Lubricants containing metal carboxylate and metal phosphate
Filed: 1959-04-01
Abstract: A lubricating composition comprises (i) lubricating oil, (ii) an alkaline earth metal salt of a C2-C5 fatty acid and (iii) an alkali metal or alkaline earth metal salt of ortho-, metaor pyro-phosphoric acid, the combined weight of (ii) and (iii) being 1-50% of that of the total composition, and there being present 1-3 parts by weight of (ii) for every part by weight of (iii).  The lubricating oil may be a mineral or synthetic oil or a mixture thereof.  Synthetic oils mentioned are alkyl esters of dicarboxylic acids, glycol esters of monocarboxylic acids, complex esters, polyglycols or their esters, silicones, formals or carbonates.  The composition may contain additional ingredients, such as viscosity index improvers (e.g. polyisobutylene), corrosion inhibitors (e.g. sorbitan mono-oleate), pour depressants, dyes, detergents and surface-active agents (e.g. polyglycols, N,N-di-(polyalkyleneoxy)-substituted fatty amines or the dioleate of an alkylated propylene diamine).  The lubricating composition may be a grease or it may be fluid.  In the latter case an additional thickener may be incorporated such as a soap, a soap-salt or mixed-salt complex, an olefin polymer, clay, carbon black or silica gel.  If desired, ingredient (ii) of the composition may be formed in situ in the lubricating oil by neutralizing the appropriate acid with the metal base.  In the examples, lubricating greases are prepared from (a) mineral oil, lime, acetic acid, trisodium or tricalcium o-phosphate, and phenyla -naphthylamine, with or without, ethylene glycol/propylene glycol copolymer and polyethylene, (b) mineral oil, lime, acetic acid, disodium acid o-phosphate, phenyl-a -naphthylamine and polyoxyalkylene-substituted fatty amine or (c) mineral oil, di (C10 oxo alkyl) adipate, lime, acetic acid, o-phosphoric acid and phenyl-a -naphthylamine, with or without alkylated propylene diamine dioleate.  In some cases the grease is heated to convert the calcium acetate therein to the anhydrous form.  In additional examples, similar lubricating compositions are described wherein the mode of preparation has been adjusted to give a fluid product.  The grease compositions of Specifications 816,318 and 797,486 are disclaimed.

Title: Watch having orientation controlled display actuator with delay
IPC: G04G21/00
Filed: 1975-03-18
Abstract: 1486696 Electronic watches TEXAS INSTRUMENTS Inc 18 March 1975 [19 March 1974] 11205/75 Heading G3T An electronic watch with electro-optical display, e.g. L.E.D.s, liquid crystal, electro-chromic, is provided with a display actuation switch responsive to the orientation of the watch and time delay circuitry which prevents actuation of the display unless the switch has been in its closed position for at least a predetermined period, e.g. ¥ second. Figs. 3a and 3b show one embodiment of the switch, which comprises a metal ball 5, e.g. of gold plated nickel, moveable by gravity in a triangular cavity and which bridges contacts 6a, 6b (not shown) when the watch is held in a predetermined orientation. Other embodiments are illustrated in Figs. 3c to 3g and 4a and 4b (not shown).  The delay circuitry 20, Fig. 5a, receives a logic "1" signal from the attitude responsive switch 4 when closed. If the switch is maintained closed for more than ¥ second then the delay circuitry emits a single 2¢ second pulse from flip-flop 33, and this causes activation of the minutes and hours display for 1“ seconds and then the seconds for 1“ seconds. The display is automatically terminated 3“ seconds after closure of the gravity switch 4. The pulse in line 34 from flip-flop 33 is initiated by the output of an AND gate 30 having a 4Hz input and a 2Hz input from stages 26, 27 respectively of the delay circuit frequency divider and a "1" input from the gravity switch. The pulse is terminated by a signal on a line 36 from an AND gate 35 which resets the flip-flop 33, a flip-flop 24 and the divider chain 26-29. In an alternative delay circuit Fig 5b (not shown), the display is not terminated after 3“ seconds but is maintained for as long as the switch 4 is actuated thus permitting the seconds display to continue as desired. The timing and display drive circuitry of the timepiece is illustrated in Fig. 1 (not shown). De-coder (724) operates digits drivers with a 23-24% duty cycle so that only one digit is activated at a time. Arrangements for setting the display to the correct time are also described. A manual push-button display switch is also provided.

Abstract: 527,479. Resin soaps and sizes; making emulsions. HERCULES POWDER CO. April 13, 1939, No. 11213. Convention date, June 30, 1938. [Classes 1 (i) and 91] A cold process resin soap is prepared by saponifying with alkali an aqueous dispersion of a pulverized gasoline-insoluble pine wood resin, produced by extracting resinous wood with coal tar hydrocarbon, removing the hydrocarbon by evaporation, extracting the residue with a petroleum hydrocarbon, and recovering the residue. The dispersion of the resin may be effected mechanically, aided or not by the use of a small amount of alkali, e.g. 10 per cent. of the alkali required for saponification, or by the use of dispersing agents, e.g. a solution of casein in sodium hydroxide, sodium oleate, sodium alginate, sulphonated higher alcohols, sulphonated naphthalenes, and bentonite. The concentration of the resin in the dispersion may vary from 10-60 per cent., but is preferably 20-30 per cent. The dispersion is saponified with alkali, preferably 20-50 per cent. caustic alkali. The dispersing and saponification may be accomplished in one operation. In the examples, products are prepared by dispersing pulverized gasolineinsoluble pine wood resin in varying quantities of water with the addition of small quantities of sodium hydroxide, potassium hydroxide or casein solution in sodium hydroxide, and saponifying the dispersion with concentrated sodium or potassium hydroxide. The concentration of total solids in the products varies from 23.9-55 per cent. and the free resin from 0-4.7 per cent. The products are used as sizing materials for paper and board.

Filed: 1922-04-21
Abstract: 180,647. Atlas-Werke Akt.-Ges. May 27, 1921, [Convention date]. Addition to 180,646. Determining bearings and distances acoustically.-In apparatus for determining distance by means of the synchronism between the receipt of a sound impulse at one extremity of the distance and the emission of a sound impulse at the other extremity, as described in the parent Specification, the emission of sound impulses is controlled by the receiving device and the distance is measured by the resulting frequency. The circuit of a sound-transmitter includes a fixed' contact K1 and a contact K2 on the armature H of an electromagnet M, the winding W of which is in a circuit containing a sound-receiver E such as a microphone. When an impulse is received at E, the current in the winding W is decreased, the armature H is released, and a succeeding impulse is sent out from a transmitter S. The frequency of these impulses, which is a measure of the distance between the transmitter Sand the receiver E, is indicated by a frequency meter A, preferably calibrated directly in meters. in a modification, part of the winding of the electromagnetic transmitter device is connected by a transformer to the circuit of the receiver microphone, so that on an impulse being received by the latter, an impulse is generated in the former.
