Abstract: 1529480 Change-speed control NISSAN MOTOR CO Ltd 12 Nov 1976 [12 Nov 1975] 47284/76 Heading F2D To obtain automatic downshift engine braking at relatively high cruising speeds on a motor vehicle having a transmission shifted automatically in response to vehicle speed and an hydraulic throttle pressure response to engine throttle opening, the transmission is downshifted by line pressure 50 supplied to a downshift line 52, leading to the shift valves, when a solenoid 54 is energized by a switch (24) closed by depression of the service brake pedal (26), after accelerator release, to shift a valve spool 56 to its leftward position, shown, in which it remains, even after de-energization of the solenoid 64 by release of the brake pedal until, on subsequent depression of the accelerator pedal (20), the level of throttle pressure applied at 48 is sufficient to move the valve spool 56 right, blocking the pressure supply line 50 and exhausting the downshift line 52 at 54 to restore normal shift speeds. The solenoid 64 is also energized for kickdown by an accelerator-closed switch (20) in parallel with the brake switch (24). A brake lamp (34) indicates closure of the brake switch (24) only, the accelerator switch being isolated from the lamp by a diode.

Title: Improvements relating to Controls for Tractors
IPC: F15B9/10
Filed: 1966-10-24
Abstract: 1,159,596. Controlling tractors. CATERPILLAR TRACTOR CO. 24 Oct., 1966 [15 April, 1966], No. 47576/66. Addition to 1,043,798. Heading B7H. [Also in Division F2] The hydraulic boosters in the steering clutch control mechanism of the tractor according to the parent Specification are modified to provide for the tractor operator an indication of clutch wear. Each booster includes a plunger 20 which is depressed upon actuation of a control pedal to close ports 30 so that oil supplied through an inlet 33 and normally discharged through drain ports 43 builds up pressure to advance a piston 19 engaging a roller 14 on a lever 13 connected to the clutch release mechanism. Ports 23 extend beyond bore 17 when the clutch is disengaged to relieve pressure on the piston. If the clutch is worn, the piston 19 occupies such a position in the bore 17 when the clutch is engaged that a flange 41 co-operates with the end of the bore to restrict oil discharge from the drain ports 43 so that back pressure within the piston exerts on the end of the plunger 20 a reaction force which is felt at the control pedal to provide an indication to the operator that the clutch is worn.

Title: Improvements in or relating to emulsions of fatty acids
Inventor: TAYLOR HARRY PELHAM
IPC: C09K23/00
Filed: 1963-12-05
Abstract: An oil-in-water emulsion of a fatty acid selected from straight and branched chain saturated and unsaturated aliphatic carboxylic acids containing at least 8 carbon atoms in the molecule contains at least 10% by weight of the fatty acid and (1) a minor proportion based on the solids content of the emulsion of at least one emulsifier selected from anionic surfactants having sulphate and sulphonate groups joined to hydrophobic alkyl or alkaryl radicals, cationic surfactants having quaternary ammonium salt groups, non-ionic polyethoxylated alcohol bodies and rosin emulsifier products comprising soaps of rosins, rosin esters and rosin Diels-Alder adducts and (2) a stabiliser selected from proteinaceous colloids, polyvinyl alcohol and sodium carboxymethyl cellulose.  The fatty acid is preferably dispersed in the aqueous phase at a temperature above its melting point; alternatively the solid acid can be suspended in the aqueous solution and dispersed using a high speed macerator. Acids mentioned are caprylic, capric, lauric, myristic, palmitic, stearic, behenic, oleic and linoleic.  Emulsifiers mentioned are sodium dodecyl sulphate, sodium dodecylbenzene sulphonate, sodium triethoxy dodecyl sulphate, ammonium hexaethoxy dodecyl phenol sulphate, sodium - 3 - (N-dodecyl carbamoyl) - propyl - 1 sulphate, sodium dodecyl sulpho-acetate, sodium tridecyl sulphosuccinate, sodium N-sulphomethylene lauramide, coconut oil ethonolamide sulphosuccinate, quaternary ammonium salts, polyethoxylated cetyl alcohol and polyethoxylated sorbitan mono-oleate.  Proteinaceous stabilizers mentioned are casein, gelatin.ALSO:Paper may be sized or material waterproofed using an emulsion of one or more aliphatic carboxylic acids containing a least 8 carbon atoms in the molecule, the emulsion containing at least one emulsifying agent selected from alkyl or alkaryl sulphate and sulphonate compounds, quaternary ammonium salts, polyethoxylated alcohol bodies and soaps of rosins, rosin esters, and rosin Diels-Alder adducts, and a stabilizer selected from proteinaceous colloids, polyvinyl alcohol and sodium carboxymethyl cellulose (see Division B1).  For paper sizing the fatty acid component is preferably less than 10% unsaturated acids, and the emulsion is added to the stock in the beater or after beating or is applied to the surface of the drying or dried web.  In an Example, the emulsions are diluted to 1% concentration, added to beaten paper stock, precipitated with aluminium sulphate and a sheet formed and dried.  Material to be waterproofed to may be of fabric, paper, ceramic, concrete or plaster.  In an Example, cotton sheeting, terry towelling and woollen fabric are made water-repellent by immersing them first in 1% alum solution and then in a diluted fatty acid size emulsion containing 0.005% to 1.0% solids, the undiluted emulsion containing 30% stearic acid, 2% sodium dodecyl sulphonate and 2% casein.
