Title: Improvements in or relating to metal alcoholates and methods of producing same
IPC: C07F3/00
Filed: 1962-12-18
Abstract: The invention comprises metal alcoholates of (a) a metal having a standard single electrode potential more positive than - 1.0 volt for the reaction M2+ + Ze --> M, and which forms an oxide of formula MO; and (b) a polyfunctional organic alcohol having a functional group attached to a C atom which is alpha or beta with respect to the carbon carrying the hydroxyl group; the alcohol is (1) a C8 to C26 alcohol having a group which is a fatty acid residue (which is defined as the residue remaining after the -O- and -OH of the carboxyl group of a fatty acid have been split off) and which contains at least 8 carbon atoms in its molecular chain, and having a group with a tertiary amino nitrogen atom attached to said alpha or beta C atom as the said functional group; or (2) a cyclic ether-alcohol which has a group with a ring ether oxygen atom attached to said alpha or beta C atom as the functional group.  The metal alcoholates are prepared by reacting the metal salt of an aliphatic or aromatic monocarboxylic acid with the aforesaid alcohol, and removing the monocarboxylic acid produced from the reaction mass. Preferred metals are nickel, cobalt, or zinc, suitably used as the acetates in the preparative reaction.  Alcohols which may be used are tetrahydrofurfuryl alcohol, tetrahydropyrane - 2 - methanol, a beta hydroxy ethyl derivative of imidazoline obtained by reaction of oleic acid with N-hydroxyethyl ethylene diamine, or a beta hydroxy ethyl derivative of imidazoline obtained by reaction of a C8 to C20 fatty acid with the same diamine. An example is given for the latter reaction, wherein the fatty acid is a coconut acid.  The alcohol is derived according to the reaction <FORM:1020055/C2/1> wherein n is 6 to 20, the residue from the fatty acid being <FORM:1020055/C2/2> whereby the minimum value for n to give the required chain of at least C8 is seen to be 6.

Title: Self-adjusting horizontal deflection circuit for cathode ray tubes
IPC: H04N3/20
Filed: 1977-11-22
Abstract: In this circuit, a regulating circuit (2) is used for changing the duration of the drive pulses of the line output stage (6) in such a manner that the amplitude of the deflection current and the reference voltages for the television receiver, generated by the output stage, are stabilised. The regulating circuit (2) has a protective circuit (10) which short circuits the drive pulses in the case of a fault, for example with an overload of the line output stage. The protective circuit (10) in the form of a flip-flop is improved to the extent that the collector of the transistor (12), short circuiting the regulator, of the flip-flop is connected via a time constant section (21, 22) to the base of the transistor (11) of the flip-flop receiving the fault information. <IMAGE>

Abstract: 1484334 Elevators VEREINIGTE OSTERREICHISCHE EISEN - UND STAHLWERKEALPINE MONTAN AG 13 Nov 1974 [14 Nov 1973] 49131/74 Heading B8L A vehicle for handling converter vessels comprises a frame 1 having wheels 7 which run on rails 9, a climbing-lifting mechanism 10 for such a vessel being disposed in the area between four turret-like projections 4 mounted on the frame 1, the mechanism 10 including a lifting frame 12 on to which a vessel 23 is directly mounted and on which two pairs of lift rams 13 are mounted, the piston-rods 14 of each pair of the rams 13 being connected by a traverse 15, the lifting frame 12 and the traverses 15 being respectively provided with extendable and retractable bolts 17, 16 which are respectively engageable in series of recesses 5a, 5 formed in the turret-like projections 4, so that if the bolts 16 of the two traverses 15 are engaged in the lowest recesses 5 in the projections 4 and if the bolts 17 are disengaged, then by extending the rams 13 the lift frame 12 and converter vessel 23 are raised and then the bolts 17 can each be engaged with one of the recesses 5a after which the bolts 16 are disengaged so that the traverses 15 can be raised by retracting the rams 13 and the bolts 16 can then be engaged in the next higher recesses 5 to support the frame 12 and vessel 23 during further extension of the rams 13. The bolts 16, 17 are extended and retracted by means of respective hydraulic 18. The frame 12 is connected via an axial bearing 19 with a rotatable frame 20, the latter having a toothed wheel rim 27 which is drivingly engaged by a pinion 28 mounted on the frame 12. If the lifting frame 12 is lowered to the extent that the frame 20 rests on the ground then by retracting the piston-rods 14 further the bolts 16 of the traverses 15 engage with the upper surfaces of the associated recesses 5 to thereby cause the frame 1 to be lifted off the rails 9, so that by driving the pinion 28 the frames 1 and 12 are rotated relative to the frame 20 so that the wheels 7 can subsequently be lowered on to different rails. A follower 21 on each of the frame 12 ends is guided between follower blocks 22 on the frame 1. Various alternative embodiments are described. For example, the bolts can be mounted on the turret-like projections (4) while the corresponding recesses can be formed in the lifting frame (12) and traverses (15), Fig. 7 (not shown).

Title: Turn-off method and circuit for liquid crystal display element
IPC: G02F1/133
Filed: 1969-10-07
Abstract: 1286828 Modulating light RCA CORPORATION 7 Oct 1969 [10 July 1969] 49178/69 Heading H4F The dynamic scattering state produced in a liquid crystal solely of the nematic type by the application of an electric field may be erased rapidly compared to the natural relaxation of the crystal following cessation of the electric field by applying an alternating voltage in the range 2-20 kHz, and preferably 7-8 kHz, to the crystal. It is believed that in this frequency range, the dipoles in the crystal are still able to align themselves with the electric field, whereas the mechanisms producing turbulence, i.e. injection of ions into the crystal have time constants which are too large. Fig. 1 (not shown) illustrates the effect of a 40 v, 10 millisecond, 7 kHz pulse immediately following a 50 v., 10 millisecond D.C. "turn-on" pulse, the turn-off time being reduced from 60 to 5 milliseconds. The alternating voltage may be left on at all times except when it is desired to produc the scattering state, and the contrast ratio may be improved by up to a factor of 2. Fig. 3 shows  a suitable circuit for one cell of an array of liquid crystal cells using transistors which are "on" only when the gate voltage is one or more volts positive relative to the source voltage, and which are all "off" in the state shown. On switching row line R bn  to +42 v., T1 is turned on but T3 remains off. If column lead Cn is simultaneously raised to + 41 v., T3 is turned on and a low frequency source 22 applies a field to the crystal 20 to produce the scattering effect. If row line R bn  is now returned to - 40 v. and subsequently column Cn is also returned to - 40 v., the charge stored in the capacitance of the gate electrode of transistor T3 keeps that transistor "on". To turn the crystal off, the voltage on row lead R an  is switched from - 40 v. to + 42 v. for about 10 milliseconds, thus turning transistors T2 and T4 on, consequently discharging the gate of T3 and removing the low frequency source 22 while admitting high frequency excitation from a source 22 to the crystal. A matrix of such elements is illustrated in Fig. 4 (not shown), wherein a row lead and a column lead must be simultaneously energized to switch a particular crystal on and the erase operation occurs a row at a time. Instead of an array of cells, a single crystal may be used with a matrix of individual electrodes.

Abstract: 1323230 Sorting digital data INTERNATIONAL BUSINESS MACHINES CORP 3 Nov 1971 [15 Jan 1971] 51032/71 Heading G4M A data processor performs an internal sort of a data sequence by producing at least two sets of output strings the expected lengths of the strings in each set being substantially equal and the lengths of the strings in one set being longer than the strings in the other set and merging the sets of strings. The data is selected to form a specified number q of short strings 82, 84, Fig. 1, and then the remaining data are selected to form p long strings 86, 88. Any remaining data is then selected to form further short strings 90. If many strings are chosen the expected or mean length of the ith string is a characteristic of the sorting algorithm used and so is known. One sorting sequence (internal sort by parameter selection) feeds the first n, e.g. 3 items of data, e.g. numbers of sequence 6, 11, 2, 8, 3, 7, 1 into a first store of length n. The lowest number in the store 1 is compared with the next number of the sequence 8. If the next number is larger the smaller number is replaced by the larger and is stored as the first number of an output strings. The procedure is repeated (comparing 3 with 2). If the next number 2 is smaller it is fed to a reject list store. When the number of numbers in the reject store is Rn where R is the parameter of the parameter selection the n numbers in the first store are added to the output string in numerical order and the output string forms the first string of the set (Fig. 2, not shown). The reject list then forms the first Rn items of the new data sequence and the process continues. A second sorting sequence (Fig. 3, not shown, an internal sort by replacement selection) stores, e.g. 3 untagged numbers into the first store and compares the next number with the lowest untagged stored number. If the next number is larger the smallest number is replaced by the next number and is stored in the output string. If the input is smaller it is tagged and replaces the smallest number which is fed to the output string. When all numbers in the first store are tagged a string is complete, the numbers are untagged and the procedure is repeated. When the sets of strings are obtained they are fed in parallel and the lowest number is selected from the parallel inputs and the remaining numbers in the selected string advanced. The new lowest is then selected &c.
