Abstract: 1,051,624. Acid zinc electroplating baths. PERNIX ENTHONE. May 20, 1964 [May 21, 1963], No.20905/64. Heading C7B. Bright zinc is electrodeposited from an acid zinc plating bath comprising a zinc compound and an inorganic acid and containing an aldehyde solubilized by a solubilizer in an appropriate  solvent and a meat protein hydrolysate. Preferably the latter which is derived from meat which has been degraded by means of a proteolytic e.g. pancreatic enzyme is added to the bath before the aldehyde and the precipitate of fatty acids and hydrocarbons produced on adding the solubilized aldehyde should be filtered off before using the plating bath as they tend to cause pitting. Specified aldehydes are aliphatic aldehydes containing at least 5 carbon atoms, e.g. 2-methyl-2-ethyl-3-dydroxy-propionaldehyde, or an aromatic aldehyde in which a benzene ring has one or more substituents in the p- or o- and ppositions, such as vertraldehyde, anisic aldehyde, piperonal, vanillin, hydroxybenzaldehyde, or 2:4 - dichlorobenzaldehyde. The aldehyde solubilizer disclosed is sodium bisulphite which should not be present in molar excess with respect to the aldehyde. An antipitting surfactant such as an alkali metal alkyl sulphate or an aromatic sulphonic acid may be included in the bath and a preservative such as 2:4:5-trichlorophenol may also be present.

Abstract: 1,051,902. Fluid pressure servomotor systems; regulating fluid flow. R. LEDUC and G. LEDUC. Jan. 27, 1964 [Jan. 25, 1963], No.3430/64. Heading G3H and G3P. [Also in Division F2] A hydraulic actuator comprises a control valve 2, Fig. 8, actuated by a torque rotor 1 in response to movement of a manual control 62, which valve controls the supply and exhaust of fluid to a chamber 50a. Movement of the valve 2 is balanced by fluid pressure in chambers 10 and 11, the chamber 10 being at a pressure upstream of an orifice 17 which is variable with temperature of the fluid and provides laminar flow while the chamber 11 is at the pressure in a conduit 12 which is downstream of the orifice 17. A chamber 50b is connected to a constant pressure source and a differential piston 40, 42 is actuated by a pressure difference to open either ball valve 38 or 39 controlling the supply and exhaust of fluid to a chamber 35 of a main jack 32 whose opposite side is connected to a constant pressure source. An electrical feedback Z and Y is provided by movements of the pistons 40, 42 and 32 to a control 68 which receives the input signal X from the control lever 62. When signal X equals the sum of Z and Y, the valve 2 closes but since the valve 38, or 39 is still open, the piston 30 continues its movement. This results in the signals Z plus Y exceeding X and the valve 2 is moved to the opposite side of central to move the piston 40, 42 in the opposite direction thus reducing signal Z while Y still increases. When the valves 38 and 39 are both closed, the signal Y equals X and the valve 2 is also closed. The system may be used to actuate air craft controls. In a modification the ram 40, 42 acts as a pivot for a manually controlled lever actuating the valves 38, 39 and the ram is moved by an electrical signal as above from an actuator pilot. The restrictor 17 is formed by a bell-shaped member 20, Fig. 4 (not shown) connected to a rod 21, in which the materials are chosen so that the changes in expansion due to temperature compensate for the changes in viscosity.
