Patent GB-402262-A (GB)
Title: Improved lubricating oils
IPC: C10M169/00
Filed: 1932-12-29
Abstract: A lubricating-oil comprises a hydrocarbon oil containing between about 0.25 and 5.5 per cent of a synthetically produced ester having a boiling point above 302 DEG F. and preferably above 356 DEG F., the lubricating oil being substantially free from suspended matter.  For ordinary lubrication, 0.25--2.5 per cent of ester may suitably be used, but for "breaking in" new engines, 2--5.5 per cent is preferable.  In general, the oils used have a viscosity of about 45--150 secs. Saybolt at 210 DEG F.  The esters used are preferably liquid, but solid esters may be employed. Mixtures of esters may be used, or the esters may be employed in combination with say soaps of lime, soda, lead or other heavy metals or a small excess of acids. Difficultly soluble esters may be admixed with more soluble esters or oils.  The acids used for the production of the esters are preferably those containing carbon, hydrogen, and oxygen only, and of these, saturated fatty acids such as acetic, propionic, butyric and like acids up through caproic, caprylic and heavier acids such as stearic acid are preferred.  Oleic acid, naphthenic acids, aromatic acids such as benzoic, salicylic and phthalic acids, hydroxylated acids such as lactic or tartaric acid, nitro- and amino-aromatic acids are also specified.  Acids produced by oxidation of paraffin wax or oil between about 212 DEG  and 320 DEG F. with air or oxygen or other agents such as nitric acid, with or without catalysts, are of especial value As the alcoholic constituent of the esters, aliphatic alcohols such as methyl, ethyl, propyl, isopropyl, butyl or secondary butyl alcohol, or the amyl alcohols are preferred, but the glycols or glycerol may also be used.  Examples relate to the use of the following esters:--isopropyl ester of the acids produced by oxidation of paraffin wax (2 per cent) (4 per cent), methyl caprylate (1.5 per cent), amyl butyrate (0.5 per cent), glycol stearate (1 per cent), secondary butyl naphthenate (1.5 per cent), isopropyl benzoate (2 per cent), phenyl acetate (1%), glyceryl oleate (4 per cent), isopropyl oleate (2 per cent), ethyl stearate (2 per cent).  The characteristics of the present oils are compared with those of oils containing soaps, fatty acids, fats, fatty oils, carbon tetrachloride or a sulphur compound obtained by cooking sulphur with paraffin wax. Specification 297,201, [Class 91, Oils &c.], is referred to.

Title: Improvements in dishwashing apparatus
IPC: A47L15/23
Filed: 1962-10-04
Abstract: 1,011,877. Dishwashing machines. GENERAL ELECTRIC CO. Oct. 4, 1962 [Oct. 16, 1961], No. 37589/62. Heading A4F.  A dishwasher including a solenoid valve for supplying washing liquid, a liquid circulating pump, and a discharge pump, is characterized in that control means provided for energizing the solenoid and at least one pump is responsive to the attainment of a predetermined level of liquid in the washing tub to effect liquid flow to the discharge pump and to interrupt the pump and de-energize the solenoid after a certain fluid pressure has been attained a predetermined number of times in the discharge of the discharge pump. The dishwasher 1 (Fig. 1) has a liquid feed valve 10, a circulating pump 20 and a discharge pump 26 with an inlet pipe 27 and an outlet pipe 28. Both pumps are driven by a single electric motor 30. Liquid reaches inlet pipe 27 by way of a siphon device which establishes the maximum level attained by the liquid before flow to the pump 26 can take place. At the downstream side of the pump 26 is provided a pressure responsive ratchet actuator 50, Fig. 4, for the electrical control means. Initially an escapement 73 is actuated by a control knob 83 to set the ratchet wheel 78 in a position such that a cam surface portion 70 thereon is engaged by a cam follower 64 to close switch contacts 62, 63, and to energize the solenoid valve 10 and the pump motor 30. The circulating pump 20 then operates for a washing cycle which terminates when the water level rises sufficiently to operate the siphon device so that the fluid pressure at the outlet of the discharge pump 26 raises a diaphragm 54 and a rod 56 to open contacts 65, 66 and close the solenoid valve 10. The pump 26 continues to operate so that the washing liquid drains away and the discharge fluid pressure drops to cause one movement of the ratchet wheel 78 and re-closure of the contacts 65, 66 to reopen the valve 10. The washing cycle is repeated until the ratchet wheel 78 has advanced to a position where a raised surface 68 or 68.1 thereon engages, a cam follower 64 to open the contacts 62, 63 and de-energize the pump motor 30 and close the valve 10. The machine may then be re-started for a rinsing operation without the addition of detergent to the water supplied through the valve 10. Detergent may be washed from a dispenser within the machine during the first washing cycle.
