Abstract: 578,490. Electric control systems. PRECISION DEVELOPMENTS CO., Ltd., and OLAH, G. April 18, 1944, No. 7171. [Class 40 (i)] [Also in Group XXIX] In a follow-up device, the brake of a servo-motor, driving the output shaft into positional correspondence with the input shaft, is applied automatically when the power is cut off from the motor, as described in Specification 556,287, and means are provided for rendering the brake inoperative when the input member moves in the same direction for a certain time or at a certain minimum speed. As shown in Fig. 1, the friction disc 19 is rotated by the output shaft 3 till it reaches stop 21, thus closing contacts 23 and so rendering the brake 18 inoperative even when the output shaft is in the same position as the input shaft 2. If the servo-motor 4 then overruns the input memoer it will be energised again by the foliow-up switch 10 and rotate in the opposite direction, so moving the friction disc away from the stop and thus opening contacts 21 to operate the brake. The brake may also be rendered inoperative when the mechanism exceeds a certain speed by means of governor 17 or a dynamo and voltage responsive relay. The friction disc may be replaced by a disc which is moved against the action of a weak spring, by eddy current action caused by a magnetic field rotating with the output shaft. Instead of the follow-up mechanism consisting of an electrical contact arrangement it may consist of hydraulic valves or mechanical couplings. Specifications 573,666 and 578,489 also are referred to.

Title: Improvements in lubrication
Inventor: SEMMENS PETER WILLIAM BRETT
IPC: C07D213/20
Filed: 1955-03-11
Abstract: Organic orthophosphates having one or two quaternary ammonium cations, each nitrogen atom of which is attached to at least one organic radicle containing at least one alkyl group having 6 or more carbon atoms are prepared by passing a solution of the quaternary ammonium halide, preferably the chloride or bromide, preferably at room temperature, through a column of an ion exchange resin, such as "Amberlite IRA400" (the word "Amberlite" is a Registered Trade Mark), which has been previously activated to give the hydroxyl form by contact with aqueous sodium hydroxide solution.  An aqueous solution of orthophosphoric acid is added to the resulting quaternary ammonium hydroxide solution, for example at room temperature.  If the monohydrogen orthophosphate salt is required, the addition of orthophosphoric acid is stopped when the pH of the solution is 8.5. If, however, the dihydrogen salt is required, the addition of orthophosphoric acid is continued until the pH of the solution is 4.5.  The solution is then evaporated to dryness.  It is stated that cetyl trimethyl ammonium dihydrogen orthophosphate and di(cetyl trimethyl ammonium) monohydrogen orthophosphate may be prepared by this method.  The cation may also be cetylpyridinium, tetradecylpyridinium, didecyldimethylammonium, stearamidomethylpyridinium, dioctyldimethylammonium, laurylbenzyldimethylammonium or p - (t - octylphenoxy) - ethyl - benzyldiethylammonium.

[Class 143] Indicating - mechanism; printed records, apparatus for giving.-Means for locking a rotatable disc associated with the indicating or printing devices of a weighing-apparatus comprise gripping devices located on opposite sides of the disc, slidable means which co-operate with each gripping device, means for effecting movement of one gripping device, and a member interconnecting the slidable means so that movement of a gripping device in one direction involves a simultaneous movement of the other gripping device in the opposite direction. As shown in Fig. 2, a pair of clamping jaws 8a, 9a situated at opposite sides of a disc 7 carried by the indicator and/or printing disc spindle are guided in parallel slideways 10a, 10b and are simultaneously pressed upon the disc 7 by a cam 19 actuated by pull-cords 21, the oppositely directed movements of the clamping jaws being effected by an intermediate lever 14. The lever 14 is also connected by a link 15 and cranks 16, 22 to an indicator 23 inscribed with the words " locked " and "unlocked." When it is desired to lock the disc 7 the right hand cord 2.1 is pulled thereby causing the cam 19 and lever 14 to clamp the jaws. Release is effected by pulling the left hand cord 21. An alternative means of effecting the locking of the disc is provided by an electromagnetic device 25 connected to the lever 14 by a strap 25a. In a modification, Fig. 6, the locking is effected by a finger piece 28 connected to the clamping jaw 8a by a spindle 29, crank 30 and link 31. An opposed clamping movement is imparted to the clamping jaw 9a by a slotted disc 32 connecting the two jaws.

Title: Method of filtering analogue signals by transferring electrical charges in a semiconductor medium
IPC: G11C27/04
Filed: 1976-02-25
Abstract: 1536020 CCD analogue filter THOMSON-CSF 25 Feb 1976 [28 Feb 1975] 07507/76 Heading H3U A method of filtering analogue signals by charge transfer in a semiconductor medium comprises the formation of input samples of the analogue signals, the introduction of these samples as charges into a charge transfer delay line which consists of two interleaved series of electrodes, the first series having constant area and the second being split into two portions, one portion representing the proportion of the input samples to be collected according to the desired characteristic, these portions being connected to a single busbar from  which the output signals are read. The two series are driven by different clock phases. As shown a two-phase clock system may be used. Analogue signals V s  applied to an input 43 are gated by a pulse waveform V e1  applied to permit corresponding packets of charge to enter each of two charge transfer delay lines. Alternate electrodes in each, 401, 405 ... and 402, 406 ..., are connected together and respectively driven by the two phases W 1 , W 2  of the clock. The intermediate electrodes in both delay lines are used to form the filtering function, being split into two 407, 427 with respective areas determining the filter coefficient, in the limit the top portion doesn't exist 403 or the bottom portion 411. The bottom portions are connected to a common output bus bar L, and the top portions also linked and connected to a D.C. source V 0  which is of smaller voltage than the clock. The output 40 is connected to a readout, Fig. 6, which has a capacitor C 0  much larger than those of the delay line stages C 1 , C 2 . When the clock pulse W, is applied to the top delay line then a pulse is applied to the gate of T 1  to charge all electrodes and C 0  to the D.C. potential V 0 . When the second clock phase pulse W 2  occurs in synchronism with the input sampling pulse V e1  then the charges moving in the lines affect the potential of the common bus L r  to give an output pulse which is transferred via T 2  to the voltage follower T 3  to the output of the filter 602. Instead of two separate delay lines it is possible to start with one set of electrodes (70, 712, Fig. 7, not shown) and by means of a heavily doped surface zone (Z) under one electrode (712) to divide the charges into two packets which can then pass under divided electrodes (721, 722) to form the filter function as before. A four-phase system may be used (Fig. 7, not shown).

A glass electrode for selectively measuring potassium ion activity in ionic mixtures including potassium, sodium, and hydrogen ions, has an ion sensing portion composed of a sodium aluminosilicate glass wherein the mole per cent of sodium oxide is equal to or greater than twice the sum of the mole per cent of alumina plus 6À25 mole per cent and contains as an additive 1 to 6 mole per cent of V2O5, the remainder being silica. The active portion is preferably composed of 20 to 27 mole per cent Na2O, 1 to 6 mole per cent of Al2O3, 1 to 6 mole per cent V2O5 and 61 to 77 mole per cent SiO2.

The molten glass was then poured into patties and annealed. The electrode was prepared by blowing a thin bulb on the end of a glass tube. The bulb was filled with an internal reference solution of 0À1 N NaCl and the stem filled with silicone oil.
