Title: Feed control device
IPC: B23Q15/013
Filed: 1974-09-25
Abstract: 1485967 Automatic feed control TOYODAKOKIKK 25 Sept 1974 [11 Dec 1973] 41758/74 Heading G3N Tool feed relative to a workpiece is increased towards a maximum feed provided that the machining torque load does not exceed a predetermined value, and, should the predetermined value be exceeded, the feed is decreased, until it is no longer exceeded, whence feed increase again takes place towards the maximum. Should the feed decrease to a pre-set minimum value without the torque load falling below the predetermined value, tool feed is stopped, signal OVT, enabling AND 1, being provided whenever the torque load exceeds the predetermined value enabling timer TMD which, with a timing sequence defined by itself and delay DLD counts down reversible counter CVT, whose content is converted to decimal form in unit CTV, for each of whose contents, 9-1, a corresponding one of relays CR9-CR 1 being energized, contacts CR9a-CR1a by-passing one or more of resistors R controlling the voltage input to voltage-to-frequency converter VFC whose output pulses, of frequency corresponding to the input voltage control feed pulse motor 10, the feed speed decreasing in a step function manner, Fig. 2 (not shown). When the torque load is below the predetermined value, AND2 is enabled, units TMU and DLU controlling up-counting of counter CUT. Should the output of converter CVT reach the value "O" corresponding to maximum feed speed, signal FMX, via NOT3, disenables AND2, up-counting thus being terminated. Should the count value from CVT attain a value corresponding to a setting, corresponding to a least allowable feed, of switch RSW, whose contacts 1'-9' are connected to corresponding CVT outputs 1-9 while the torque load exceeds the predetermined value, a signal FMN, via NOT4 and AND4 stops the motor 10, and, via NOT1 stops further down counting of CUT. In a modification, Fig. 3, (not shown), a single timer and delay units (TM, DL) are used to control either up- or downcounting of counter CUT. The overall feed range may be adjusted by suitably setting the level of voltage +V. The feed control is stated to be useful in situations where the cutting ability of a tool decreases during a machining operation, or for machining workpieces of non-uniform hardness or surface roughness.

Abstract: 1,162,159. Automatic attitude control. NORD AVIATION SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. Sept. 21, 1966 [Nov. 13, 1965], No. 42254/66. Heading G3R. The axis of symmetry of an aerial vehicle rotating at constant speed about its centre of gravity is maintained in a given direction by detecting deviations therefrom at successive instants determined by the relative position of the axes of rotation, angular momentum and conical roll, and applying corrections automatically at immediately following instants. In Fig. 12, an artifical satellite (not shown) rotates slowly round its longitudinal axis Gz about which it forms a solid of revolution having two other perpendicular axes Gx, Gy. If, as shown, the axis Gz has deviated from a desired direction GZ, e. g. that of the sun, and the satellite has angular momentum about an axis GH, a photo-cell arrangement 23 detects the magnitudes of angular deviations in mutually perpendicular planes so that corresponding torques are automatically produced by pairs of gas jets 13a, 13b to correct the attitude deviation. Correction torques are applied intermittently when the jets are in such positions that the directions of thrust are appropriate for attitude correction. The intervals between corrections are determined by a timer which is set according to the speed of rotation of the satellite and the magnitudes of its moments of inertia about longitudinal and transverse axes. After each interval the timer operates to store the altitude deviation signals capacitatively, and after the next interval the timer adjusts the biasing of rectifiers so that the stored signals are applied to produce corresponding thrusts and replaced by new deviation signals in readiness for the next correction. The attitude deviation detector is displaced relative to axes Gx, Gy by an amount sufficient to allow for movement of the satellite during the application of thrust. Detection of deviation relative to an attitude defined by coherent light or a radio or magnetic field, and application to the control of missiles, are referred to.

Title: Heterocyclic dyestuffs derived from benzanthrone and process for their manufacture
IPC: C09B5/24
Filed: 1959-12-21
Abstract: Spinning compositions of viscose, cellulose esters or polyacrylonitrile are dyed brown with a dye of the formula: <FORM:0894150/IV (a)/1> where A is an alkylene radical or a substituted or unsubstituted aromatic residue in which the two -CO- groups or the -CO- group and the -C = C-group which are attached to the same nitrogen atom are separated from one another by 2 or 3 carbon atoms, n is 1 or 2 if A is aromatic or n is 1 if A is alkylene, and R is hydrogen or an organic residue and where the benzanthrone residue or residues may be further substituted.  When the above dyestuff is used in high-melting spinning compositions such as superpolyamides or polyethylene terephthalate, ring closure in the melt occurs and the violet dyestuff of the formula:  <FORM:0894150/IV (a)/2> is formed.  The dyestuff of formula (2) may also be used directly for dyeing viscose, cellulose esters, polyacrylonitrile, polyamides, e.g. nylon, and polyesters, e.g. polyethylene terephthalate spinning compositions.  In examples, dyes of the formulae (1) and (2) are each "bread-crumbed" with (6) hexamethylene diamine and adipic acid and (7) polyethylene terephthalate, and spun to yield violet fibres.ALSO:The invention comprises dyestuffs of the formulae <FORM:0894150/IV (c)/1> where A is an alkylene radical or a substituted or unsubstituted aromatic residue in which the two -CO- groups or the -CO- group and the -C=C- group which are attached to the same nitrogen atom are separated from one another by 2 or 3 carbon atoms, n is 1 or 2 if A is aromatic or n is 1 if A is alkylene, and R is hydrogen or an organic residue, and in which dyestuff the benzanthrone residue or residues may be further substituted. Aromatic residues specified for A are derived from benzene, naphthalene, anthraquinone and pyridine and alkylene residues specified are ethylene, propylene and vinylene.  The dyestuffs are made by heating one molecular proportion of an acid of the formula <FORM:0894150/IV (c)/2> or its anhydride or acid halide, when n is 1 with one molecular proportion or, when n is 2 with two molecular proportions of an amine of the formula <FORM:0894150/IV (c)/3> at temperatures below the melting point of the brown or grey cyclic imide obtained which is of the formula (1) above, and if desired heating the imide above its melting point to obtain the violet dyestuff of the formula (2) above, and if desired subjecting this to halogenation.  Examples are given.  The dyestuffs are used in spin-dyeing (see Group IV(a)) and some may be used as vat dyestuffs.

As described, gallium phosphide LED's are used, their colour being predominantly red, yellow or green in accordance with the applied current level, Fig. 3. The apparent brightness of the display is varied by varying the energization time of the diodes. Each column is accessed in turn by register 19 whose outputs render transistors 18, 18a... conducting in turn, while the outputs of register 16 determine which diodes 13 in the column shall be energized. Signal 20 thus contains n groups of 2m-bit signals (2 bits for the colour of each of m diodes): these are fed to 16 via a circulating register 17 which allows the LED's to be repeatedly and rapidly energized to  simulate a stationary display. The 2-bit outputs from 16 are each fed to means 15,... which comprise bi-stables 40, 41, Fig. 4, AND gates and transistors 52-54 connected to current sources by resistors. Depending on the two bits 38, 39, one of these transistors is energized for a time period depending on an associated signal 35-37 from a brightness control 34, and acts to provide current at one of three levels to the corresponding row of n diodes. Alternatively (Fig. 5, not shown) each 2-bit colour signal may be associated with a further 3-bit signal (in Graycode) to indicate the brightness level required, this signal being decoded to cause the colour signal to be transmitted as a maximum of seven rapid pulses at the appropriate current level.
