Inventor: WOOD FRANK
IPC: B23Q5/20
Filed: 1955-10-11
Abstract: 824,169. Lathes. ARNFIELD Ltd., J. & E. Oct. 5, 1956 [Oct. 11, 1955 (2)], Nos. 28988/55 and 28989/55. Class 83 (3). A lathe, particularly adapted for producing pump-rotors having an eccentric lobe following a helical path around the axis of the rotor, includes means for maintaining the rate of rotation of the work and the rate of tool-traverse in accurate synchronism. In an electrical transmission for effecting this synchronism, Fig. 1, a headstock centre 5 mounted eccentrically on a spindle 9 integral with a differential planet carrier 11 supports one end of the work. The spindle is carried in a rotatable sleeve 6 provided with a work-driver 7 and driven by a worm 8. A sun-wheel 60 integral with spindle 6 meshes with planet gears 24 of the differential. The stator of a synchronous electric transmission device 28 of the Selsyn type is rigidly mounted on the planet carrier 11, and differential gear member 27 is mounted on its rotor. The outside of the planet carrier 11 is formed as a spur gear 12 which meshes with a gear 13 carried by a shaft 14. The latter is connected through a train of gears and clutches to the lathe lead screw 18. An intermediate gear 20 of this train is coupled through a clutch 21 to a setting-motor 22, and the second member 23 of the synchronous electric transmission. When the clutch 16 is disconnected a motor 19 may be brought into operation for rapid traverse of the tool in a return or idle movement. A device is described for incorporation in the headstock spindle for bringing the spindle 9 and sleeve 6 into a predetermined angular relationship at the commencement of each cutting operation. An hydraulic transmission is described which may be substituted for the Selsyn units. Specifications 400,508, [Group XXVI], and 776,754 are referred to in the Provisional Specification.

Patent GB-715774-A (GB)
Title: Improvements in or relating to process for betaine recovery
Filed: 1951-12-14
Abstract: Betaine is recovered from a residual liquor of beet molasses by treating it with ammonium chloride or a metallic chloride which is more soluble in water than potassium chloride and is in sufficient amount to substantially saturate the liquor, adding mineral acid to the solids-free liquor in sufficient amount to precipitate the betaine therein as the betaine mineral acid addition salt and separating said salt therefrom.  Preferably the residual liquor of beet molasses, e.g. Steffen's filtrate, is heated to a temperature between 40 DEG  and 105 DEG  C. before the addition of the chloride. Suitable metallic chlorides for use in the process are, for example, those of calcium and magnesium.  In the example unconcentrated end liquor of concentrated Steffen's filtrate is heated to 50 DEG  C., calcium chloride is added and the mixture is filtered; hydrochloric acid is added and betaine hydrochloride crystallizes out.

Title: Improvements in or relating to signal amplifying devices
Inventor: HOWES KENNETH JUSTER
IPC: G05D23/24
Filed: 1958-09-12
Abstract: 872,816. Non-linear amplifier circuits. SMITH & SONS (ENGLAND) Ltd., S. Dec. 11, 1959 [Sept. 12, 1958], No. 29369/58. Class 40(6) [Also in Group XXVI] An amplifier comprises a number of parallel connected channels, having different input/ output characteristics and means responsive to the amplitudes of the outputs of at least some of the channels to control the application of the channel outputs to the amplifier output. As described an input signal is fed to two amplifiers 23, 24 the outputs of which follow the laws a+bv and c-dv respectively, where a, b, c, d are constants. The outputs from the amplifiers are fed to the output terminal 36 via rectifiers 27, 29, and a constant potential applied to terminal 32 is also fed to the output via rectifier 31. The three rectifiers 27, 29, 31 are arranged such that only the one to which the largest signal is applied becomes conductive to connect its corresponding signal to the output line. The resulting output characteristic is therefore trough shaped. An amplifier as described may form part of a fuelsupply control system for a gas turbine (see Group XXVI). The amplifier input is fed from a tacho-generator via a potential divider network containing a temperature sensitive resistor 20 exposed to the compressor input air stream, and the input is thus a function of both speed and input temperature. The output, which represents the maximum permissible exhaust gas temperature is fed to a resistive network, containing a further temperature sensitive resistor 34 exposed to the air stream and another resistor 33, the values of the resistors being such that output at their junction is approximately proportional to the maximum permissible exhaust temperature over the expected range of input temperatures. At low running speeds, a relay 25 is de-energized, and the output at terminal 36 is limited by clamping diode 37 to the potential applied to terminal 41, at high speed the relay is energized and the limiting potential is that applied to terminal 42, which is lower. These potentials correspond to the maximum permissible exhaust gas temperature for short intervals, and for steady running respectively for avoidance of thermal damage.
