Abstract: 868,810. Preventing and removing incrustation and corrosion. SABINS, R. C. Oct. 14, 1957, No. 32018/57. Class 123(1) An electrolytic system comprises an electrolyte, a cathode 21, an anode 23, and an intermediate electrode 22 which is higher. in the electro-chemical series than the cathode. An external circuit 26-28 maintains the polarization of the electrode to prevent dissolution of the electrode, and a similar circuit 34, 35 prevents dissolution of the cathode. The current in external circuits may be provided by a D.C. source such as a battery or generator, or by suitable disposition of the anodes/cathode/electroder materials in the electro-chemical series. The potentials of the cathode and electrode may be measured by means of a half-cell 38 which may be of silver-silver chloride which may be connected by a suitable switching circuit through a milli-volt meter 40. When the measuring circuit is not in use, the switch arm 54 bridges contacts 52, 53 connecting a battery 51 which depolarizes, the half-cell. The system may be used for the protection of pipe work, a ship's hull, or may be used to liberate a poisonous substance by suitable choice of anode material. Specifications 868,819 and 868,820 are referred to.

Title: Device for controlling the slats of blinds
IPC: A47H5/032
Filed: 1973-07-06
Abstract: 1415747 Vertical slat blind FRANCIAFLEX 6 July 1973 [8 Aug 1972 11 Oct 1972] 32418/73 Heading 1EJ [Also in Division F2] A blind has vertical slats pivotably supported from runners 5 which are translatable in a guide I and are connected by a flexible link, a cord 11 attached to the leading runner passing round a drive pulley 12 to effect translation, a rod 18 having worm gears engaging pinions on slat carrying shafts in the runners effecting pivoting of the slats, a single rotatable member 19 controlling the drive pulley and rod via respective clutches. When rod 19 is rotated, sun gear (20, Fig. 2) drives gears (22) to stops (23) and the pulley 12 is then rotated and causes cord 11 to draw the leading runner 5 along. Before the pulley 12 becomes operative, bevel gear (24, Fig. 3) drives gear (25) which drives gears (27, 28) and a. shaft (30) which is connected by contracted spring (31) to shaft (35) fastened to rod 18 and the slats are thus turned until perpendicular to rail 1. Sleeve (36) then becomes movable and allows spring (31) to expand and release shaft (30), thus stopping pivoting. At this point the pulley 12 becomes operative and the slats are translated. In an alternative connection (Fig. 8 not shown), rod (19) moves bevel (50) to operate rod 18, and pivot the slats, until gears (22) are stopped, spring (65) then expands releasing rod (19) from the gears. Disc (59) then rises and releases tongues (54) from teeth (56) allowing sleeve (53) to turn and tighten spring (57) on rod 19 so that it drives pulley 12 to translate the slats. In Fig. 9 (not shown), the rod 19 is again connected to pulley 12 by planetary gears 74.

Title: Shaft Angle Encoding
IPC: H03M1/00
Filed: 1967-07-14
Abstract: 1,197,085. Selective signalling. ITEK CORP. 14 July, 1967, No. 32468/67. Heading G4H. In a shaft position encoding system interpolation between scale divisions of the least significant track of a conventional coded scale is effected by quadrature sensing of the track, by combining the resulting signals, which will vary sinusoidally with position, in a plurality of resistance networks to produce a plurality of further signals (which will also vary sinusoidally with position) whose phases, with respect to one of the original sensed signals, will all be different and will cover uniformly a complete cycle of positional variation of the original signals, and then by examining these further signals sequentially, and counting those examined, until their polarity changes. The count attained then effects the desired interpolation. Thus if the sensed signals are sin # and cos #, where # represents position within one cycle of the divisions of the least significant track, then for an interpolation factor of eight, for example, these two signals are combined linearly in four resistance networks to produce the four signals sin (#-r#/4), r = 0, 1, 2, 3. As # increases from 0 to 360 degrees the following eight different combinations of polarities occur: and the particular quadrant in which 0 lies can be determined either by counting the number of plus signs, or, if the first sign is a minus, by inverting the signs and then again counting the plus signs, this count being increased by 4. A block diagram of a suitable circuit is given using a magnetic core counter and conventional transistor gates and amplifiers. The preferred method of sensing the scale is photo-electric but other methods, namely brish, capacitative, and inductive, are mentioned.
