Abstract: 1,099,370. Automatic speed control. NEWTON BROS. (DERBY) Ltd. April 5, 1965 [April 3, 1964], No. 13906/64. Heading G3R. The speed of an electric motor, or the frequency of a motor-alternator set, is controlled by rectifying, smoothing, and stabilizing a part of the output voltage of the alternator or tachometer to provide a reference voltage, another part of the output being applied to a frequencysensitive network the output from which is rectified, smoothed, and compared with the reference voltage to provide an error signal. This signal is amplified and applied to the control winding of a carbon pile regulator in the field circuit of the motor. The stabilization of the reference voltage is effected by Zener diodes, the voltage comparison and amplifier networks employing transistors. A long-tailed pair of transistors are connected across the stabilized reference voltage source with the transistors in common emitter mode. A fixed voltage derived from the reference voltage source is applied to the base of one transistor and the voltage from the frequency-sensitive, network to the base of the other transistor. The error signal is developed in the collector circuit of the first transistor.

Title: Aldonate compositions and method for the production thereof
IPC: C07C59/105
Filed: 1947-05-28
Abstract: A clear green aqueous solution of a chromic aldonate is obtained by mixing together an aldonic acid and an aqueous solution of a trivalent or hexavalent chromium compound, the solution of the chromium compound being made in the presence or not of alkali, the ratio of the number of aldonic acid molecules to the number of chromium atoms being at least one to one.  The chromium compounds used as starting materials include chromic anhydride, sodium dichromate, sodium chromate, chromic hydroxide, potassium chromate and potassium dichromate.  The preferred aldonic acid is gluconic acid but others mentioned are mannonic, arabonic, galactonic and xylonic acids.  The alkali if present may be sodium, potassium or lithium hydroxide and it is preferred to use a ratio of a number of chromium atoms to a number of alkali metal atoms within the range of 1 : 1 to 1 : 3, a ratio of a number of chromium atoms to aldonic acid molecules within the range of 1 : 1 to 1 : 3 preferably 1 : 1.7 and a ratio of the total number of alkali metal atoms plus aldonic acid molecules to chromium atoms of at least 3 : 1.  When alkali metal ions are present during their formation the chromic aldonates will contain alkali metal atoms.  In examples: (1) sodium hydroxide is added to an aqueous solution of chromic anhydride, a solution of sodium chromate being formed, an aqueous solution of gluconic acid containing dextrose or other reducing sugars is then added and a deep green solution is formed which does not form chromium ions in solution and does not precipitate or coagulate on standing; (2) as in (1) except that sodium dichromate is used instead of chromic anhydride and sodium hydroxide.  The aldonate solutions are useful as anti-burn agents when added to zinc cyanide electroplating baths (see Group XXXVI), and make it possible to deposit zinc over a wide range of current densities.  They may also be used as water colours and mordants.  Specification 395,003 is referred to.
