Abstract: 1,253,326. Antiferroelectric materials. UNITED STATES ATOMIC ENERGY COMMISSION. 16 March, 1970 [11 April, 1969], No. 12474/70. Heading H1K. [Also in Divisions G2-G3 and H2] A voltage regulator for connection in parallel with a power source and a load (see Divisions G2-G3) comprises a stack of antiferroelectric elements 20a ... 20d sandwiched between pairs of electrodes 22a ... 22d, 24a ... 24d, the inner ones of which are bonded together by conductive adhesives 30, 32, 34. The antiferroelectric material may comprise compositions in either ceramic or single crystal form including solid solutions of lead zirconate-lead titanate, lead hafnate-lead titanate, lead zirconate-lead stannate-lead titanate, and others including barium, calcium and/or strontium. These solutions may be further modified to provide one or more desired characteristics, such as a particular hysteresis loop shape, by additions of about 0À1 to 4À0 atom per cent of one or more of the oxides of niobium, antimony, bismuth, tantalum and lanthanum. A particularly useful composition is stated to be:- where y ranges from about 0À14 to 0À16. For applications above room temperature a suitable composition is :- and  Another suitable material having a narrow loop hysteresis characteristic is:- The electrodes may be of copper, aluminium, silver or gold and may comprise a foil or plate adhered to the material by firing, plating or evaporating. Adhesives 30, 32, 34 may be epoxies or other resins. The stack may comprise a number of standard elements to which is added an element of sufficient thickness to provide the required voltage regulating level. The cross-section of the stack is chosen to prevent the material saturating over its operational voltage range.

Title: Process for the dehydration of inorganic salts and bases
IPC: B01D3/34
Filed: 1944-07-06
Abstract: Anhydrous substances are produced from inorganic bases or from inorganic salts which do not give an acid solution when dissolved in water by heating the aqueous solutions of such substances, or the solid substances containing moisture or water of crystallisation, with an excess of an acetal, a ketal or a di-ether of ethylene glycol or homologue thereof.  The organic substance chosen should be a liquid at 100 DEG C.  A mixture of these "acetal-like bodies" may also be used.  The process may be applied to the alkali, copper, ferrous and magnesium sulphates and also to barium, lithium, calcium and cupric chlorides. Crystalline barium chloride (100 parts) is pulverised and mixed with 500 parts of acetaldehyde-dibutyl-acetal in a vessel provided with an outlet leading to a condenser and having a stirrer mounted therein.  The mass is heated, while being stirred, to the boiling point of the acetal, and a mixture of water and a small amount of acetal is distilled off.  When the dehydration is complete, the excess acetal is separated from the barium chloride by filtration or by centrifuging.  The last traces of acetal may be removed from the barium chloride by tumbling it in a box through which a current of hot air is passed.  The product is very fine and can be used as a catalyst for splitting hydrogen chloride.  Instead of the crystals, a saturated solution of barium chloride can be similarly treated.  When potassium hydroxide is treated by this process, it is recovered as a complex with the acetal-like body used.  Specification 582,191, [Group IV], is referred to.ALSO:A complex of potassium hydroxide with an acetal, or a ketal, or a di-ether of ethylene glycol or homologue thereof is prepared by heating moist solid potassium hydroxide or a concentrated aqueous solution thereof with the "acetal-like body" until all the water is driven off.  The products may be used as catalysts in the condensation of calcium carbide or of acetylenic hydrocarbons with aldehydes or ketones.  Specification 582,191 is referred to.

Abstract: 1,080,823. Transistor sawtooth circuits. RADIO CORPORATION OF AMERICA. March 26, 1965 [April 3, 1964], No. 12951/65. Heading H3T. A deflection circuit for a cathode-ray tube comprises an amplifier coupled to deflection coils 18, the amplifier being responsive to the difference between a deflection waveform input 68 and a voltage representative of the amplifier output current, the deflection coils being shunted by a circuit (e.g. 92, 94) for compensating for non-linearities resulting from factors outside the control loop of the amplifier. As shown, a colour television camera comprises an image orthicon luminence tube 76 and a plurality of vidicon chrominance tubes 10. The deflection current for the image orthicon 76 is provided by transistor 82, a shunt 88 providing a sawtooth voltage 90 representative of the current. Waveform 90 is amplified at 72 and fed to an amplifier comprising transistors 51, 42 feeding a corresponding current to the deflection coils 18, 20 of the vidicon 10. The output current i D  is fed back to the emitter of transistor 51, providing a corresponding voltage waveform across resistor 66. Transistor 51, acting as a differential amplifier, is thus responsive to variations between the required waveform 68 and the output waveform i D . The inductance 92 of the linearity correcting circuit should have an impedance at the deflection frequency greater than that of resistor 94 whilst the impedance of the path comprising components 92, 94 should be greater than that of the deflection coils 18, 20.

Abstract: 1,160,929. Selective signalling. ITT INDUSTRIES Inc. 22 March, 1967 [25 March, 1966], No. 13461/67. Heading G4H. [Also in Division H3] A frequency-selective switching circuit has one transistor for each frequency to be received and diodes connecting the output of each transistor to the inputs of the others so that only one of the latter can conduct at a time. As applied to the remote tuning of a television receiver (Fig. 2) control signals are applied at B1 to tuned circuits # 1 , # 2 , # 3 , one of which will respond and allow conduction of the corresponding transistor which rectifies the signal. If T 1  conducts, diodes D 12  and D 13  will bias off the other transistors through D 2  and D 3 . Current flowing through collector load potentiometer P 1 , P 2  or P 3  causes a predetermined voltage to be applied to capacitance diodes (not shown) which form the tuning elements. At the same time another predetermined voltage is taken off from P<SP>1</SP> 1 , P<SP>1</SP> 2  or P<SP>1</SP> 3  to set other parameters to the optimum for the channel being received, e.g. brightness, contrast or sound volume. Glow tubes G 1 , G 2 , G 3  indicate which channel is in operation and local control can be effected by manual or electronic switches S 1 , S 2 , S 3 . The signals at B 1  may be derived from acoustic, optical or electromagnetic control signals. Series-resonant or other filter circuits may be used instead of parallel resonant circuits. Diodes D 1 -D 3  may be omitted if the baseemitter threshold of the transistors is greater than the sum of the collector-emitter saturation voltage and the forward drop across diodes D 12  &c. The potentiometers P 1 -P 3  may be replaced by relays which control a tuning motor.

Title: A process for the manufacture of multi-coloured patterned articles
IPC: B44C3/04
Filed: 1935-05-07
Abstract: In a process for the manufacture of a preliminarily moulded multicoloured patterned article in which the pattern extends completely through the article, layers of differently coloured moulding powders are superimposed in a channel or trough, the surface of each layer being shaped by means of a die, and the layers are then pressed together, if necessary with the application of moderate heat. The binding of the layers may be released, for example by shaking, before the layers are pressed together.  The finished articles are produced by applying heat and pressure to the preliminarily moulded articles, or to parts cut therefrom, in the known manner.  The moulding-powders may comprise heat-hardenable artificial resins and albuminous substances such as horn powder.  When introducing a layer of powder into the channel or trough, powders of various colours may be shaken through one another, whereby the layer may be multicoloured or shaded.  The preliminarily moulded article may be employed for decorating an article formed from the same moulding powder by applying it to a layer of unpatterned powder and compressing the whole.
