Title: Improvements in screw making and turning
IPC: B23B7/02
Filed: 1923-01-05
Abstract: 217,257. Braren, L. K. Jan. 5, 1923. Combined turning, drilling, and screwing machines; chucks.-The reciprocating stock-feeding gripper of a hollow-spindle automatic lathe is actuated by a member which also impaa-ts corresponding longitudinal movement to the cutting-off tool. The lathe-spindle 3 is driven through gearing by a shaft 2 which also drives a screwing-die or drill spindle 7 at a speed different from that of the lathe-spindle. A cam shaft 8 carries cams 9, 10, 11, Fig. 3 which actuate respectively the cutting-off tool 45, the turning- tool 48 and the forming-tool 47 in directions transversely of the work. The cutters may be circular or flat and may be adjusted on their carriers in any direction. The cutting-off toolcarrier has arms 28, 25, Fig. 1, journaled on ballbearings on casings 39, 35 surrounding the shaft 2 and has depending lugs 24, Fig. 3, whereby it is rocked by the cam lever 12 which turns on pivots 14, 15, a screw adjustment of the contact' roller 20 permitting oscillations of varying amplitude to be imparted to the cutting-off tool. An arm 30, Fig. 1, located between the arms 25 and engaging a groove 53, Fig. 4, on the feed gripper, is actuated by mechanism (not shown) in order simultaneously to feed the stock and to traverse the cutting-off tool. The feed mechanism comprises a pair of split collars 61, 64, thrust axially in the same direction by springs 62, 66 and closed by balls 60, 65. The stock 63 is fed by the forward movement of the collet 61 and is restrained from retrograde movement by the collet 64, which is substantially stationary in an axial direction. The collets are countersunk at their entering ends. The forming-tool carrier 40 partakes of the longitudinal motion of the cutting-off tool, but the turning tool does not move axially. An oil guard 75 is provided at the end of the lathe spindle and lubricating holes in the traversing sleeve of the feed mechanism are feltlined. A slotting-arm receives each screw after the threading-operation and conveys it to a slotting-saw after cutting-off.

Title: Improvements relating to multiplex high frequency systems
IPC: H04J3/04
Filed: 1931-01-06
Abstract: 370,445. Multiplex wireless signalling. KOLSTERBRANDES, Ltd., Cray Works, Sidcup, Kent.-(Kolster Radio Corporation ; 200, Mt. Pleasant Avenue, Newark, New Jersey, U.S.A.) Jan. 6, 1931, No. 447. [Class 40 (v).] The individual cycles of a carrier current are divided into units or groups of units containing an integral number of cycles corresponding to the number of messages to be transmitted, and modulated in regular sequence by currents corresponding to the respective messages. In one embodiment for transmitting three messages simultaneously a three-phase generator 10, Fig. 1, of one-third the carrier frequency, has one of its phases multiplied in frequency by three at 11, to provide the carrier. Three modulators 12, 13, 14 equipped with microphones 15, 16, 17 and amplifiers 18, 19, 20 respectively are brought into operation successively by the positive half-cycles of the three phases, their outputs being combined and feeding a master carrier modulator 18<1> with output circuit 19<1> leading to the transmission channel. By opening switch 40 and closing switch 41 one of the phases may be used to control the connection of a low frequency telephone circuit 44 to the outgoing line while a further telephone circuit 46 may be connected directly to the line. The output may be taken to a three or other suitable phase converter 20<1> producing a multiple phase high-frequency current triply modulated on each of its phases in the circuit 21. At the receiver the carrier passes to a detector valve 23, Fig. 2, a beat frequency of one-third of the carrier frequency being produced in its output circuit by coupling to a local oscillator 24. This beat frequency is detected by valve 25 and heard in telephones 26. The phase of oscillator 24 may be adjusted to bring in either of the three messages. The suppressed half-waves of the three-phase generator and carrier may be utilized to provide three more channels. In an alternative method of transmission the carrier is generated single phase by generator 28, Fig. 4, and modulated at successive intervals by modulators 12, 13, 14, activated by a three-phase current at successive intervals of 120‹ of the three-phase cycle. The three-phase current is generated by a converter 29 comprising a star or delta connected coil system 30 coupled to a rotating field set up by a phase splitting circuit 31 tuned to one-third of the carrier frequency and energized by transformer 32 from the generator 28. The positive or negative half cycles of the carrier and three-phase circuits may be suppressed by rectifying valves or otherwise. An alternative receiving circuit has a rotating field system 37, Fig. 5, energized by the amplified carrier, and a coil system 39 arranged therein, the impulses from which, at every third cycle of the carrier frequency, overcome the negative bias of detector valve 35 allowing one message to pass. By rotation of the coil system 39 any of the three messages may be selected.

Title: Improvements in or relating to complex salts of stabilized rosin amine
IPC: C09F1/00
Filed: 1948-01-12
Abstract: At least two molecular proportions of a stabilized rosin amine are mixed with one molecular proportion of a complexogen metal salt to form a homogeneous resinous complex.  The term stabilized rosin includes hydrogenated, dehydrogenated and disproportionated rosin. The amine is formed by reaction with ammonia to form a nitrile which is then reduced.  A complexogen metal salt is a salt capable of forming complex amine salts with ammonia, e.g. acetates, nitrates, halide, propionate, stearate or sulphate of copper, zinc, chromium, mercury, silver, aluminium, manganese, iron, cobalt, nickel, calcium or cadmium.  The reaction may be performed in solution, e.g. in alcohol, chloroform, carbon tetrachloride, hexane, benzene, naphtha, toluene or xylene.  The solvent may be evaporated to yield a solid product or the product may be used in solution.  The products are useful for impregnating fabrics, ropes, &c. (see Group VIII), as mildewicides or fungicides.  They may be used in conjunction with chlorinated hydrocarbon flame inhibitors on which they exercise a stabilizing action.  They may also be used in rubber compounding, in asphalt compositions, lubricating compositions, in tanning or preserving leather, in metal corrosion inhibitors or paints and varnishes.  In example (1) cupric acetate was added to hydrogenated rosin amine dissolved in a petroleum solvent, and the mixture heated to 60 DEG  C.  Example (2) uses disproportionated rosin.  In example (3) zinc chloride is added to disproportionated rosin amine in carbon tetrachloride.  The product may be precipitated by addition of hexane.  Ethanol may be used as the solvent.  Other examples are similar.  The anion of the complex may be changed for another anion by addition of an acid or soluble salt to the complex.  Thus in example (8) sulphuric acid dissolved in ethanol was added to a zinc acetate complex of dehydrogenated rosin amine and example (9) to the copper acetate complex of dehydrogenated rosin amine.

Title: Method and system for analyzing inspection point of logical circuit and semiconductor integrated circuit with inspection point
Inventor: NAKAO NORINOBU
IPC: G01R31/28
Filed: 1997-01-06
Abstract: PROBLEM TO BE SOLVED: To realize high speed inspection point analysis in practical stage and to reduce overhead of the inspection point circuit area of a semiconductor integrated circuit. SOLUTION: An inspection point index calculating section 111 calculates inspection point index information 123 including CRF (approximate cost of test) of each signal line from circuit information 122, determines a predetermined number of candidates of inspection point on the order of CRF and then calculates a COP (cost of test) while assuming insertion of each candidate of inspection point. An inspection point determining section 112 determines a candidate having lowest COP as an inspection point, searches other candidates of inspection point which do not intersect the influence range of the inspection point on the ascending order and adds a searched candidate, if any, to new inspection points. Subsequently, a candidate which does not intersect the influence range of the additional inspection point is searched based on the additional inspection point.  When the number of inspection points is lower than a set value, inspection point index information 123 of logical circuit including a preset inspection point is calculated again and the process is repeated. A inspection point correlation information 126 where a set of inspection points having nonintersecting range is grouped is imparted. An inspection point influence calculating section 113 calculates a range having effect on the CRF in the circuit based on a just set inspection point.
