Title: An improved method and apparatus for simultaneously spinning and twisting artificial threads
IPC: E02F3/14
Filed: 1936-03-25
Abstract: A method for spinning and simultaneously twisting artificial threads consists in spinning the threads from a rotary spinning nozzle into a vessel, rotating with the nozzle, and maintained practically completely filled with precipitating liquid during the spinning.  The spinning solution is supplied by spindle A to nozzle B located inside the spinning bath vessel C.  The vessel C is closed at the top by a cover D sealed by a rubber jointing ring.  A tube F forming the lower portion of a funnel G is removably inserted into the centre of the cover D, a sealing joint J preventing leakage.  A thread guide K fixed to the underside of the cover consists of upper and lower bars curved <PICT:0460744/IV/1> <PICT:0460744/IV/2> in one direction and a central swingable bar curved in the other direction, and prevents the twist running into the space between thread guide and nozzle. Precipitating liquid is introduced through a feed pipe M into funnel G and is discharged through fine holes L in the vessel C.  In a modification of the apparatus, the spinning nozzle B and rotating spinning bath vessel C are driven by a motor A<1>.  The vessel is sealed by a cover D with outlets L, and a sealing ring E.  The funnel member G is connected by an elastic connection J with a rotating sleeve F<1> which conveys the precipitating liquid straight down to the spinning nozzle.  The sleeve F<1> carries the thread guide K at its upper end.  The vessel C is enclosed in a casing H<1> which supports the funnel G.  Precipitating fluid passing from vessel C by outlets L is thrown out against the casing H<1> and drains off at the bottom.  The inner walls of sleeve F may be formed with a number of longitudinal lines and a device may be provided in the funnel G to prevent eddying of the liquid.

Title: Material applicator for planographic printing machines
IPC: B41L39/16
Filed: 1938-03-24
Abstract: 499,810. Printing - machines. ADDRESSOGRAPH - MULTIGRAPH CORPORATION. March 24, 1938, No. 9066. Convention date, June 10, 1937. [Class 100 (ii)] Inking and damping apparatus.-A planographic printing-machine is constructed with one control member which permits the damping and inking apparatus to be put out of action individually, or both at once, and improvements in the damping and inking apparatus include means for mounting the damping- rollers so as to be withdrawn readily, and means for operating the messenger rollers so as to cause them to engage the fountain rollers with even pressure at each end, and so as to have a dwell when in contact both with the fountain rollers and the applying rollers. As applied to a machine of the kind described in Specification 499,800, and having means for mounting and actuating the inking and damping rollers as described in Specification 499,800, the plate cylinder B of an offset machine is inked by a roller 64 and receives water or other repellent from a roller 45 both held normally in contact with the cylinder by spring action and supplied by messenger rollers 55, 35 respectively which are moved into and out of contact with the fountain rollers 51, 32 by a cam on the shaft 15 of the offset roller and lever-and-link mechanism including reciprocating links 108, 114, Fig. 3, which are frictionally connected to the pivotal mountings of the messenger rollers and can move relatively to these after the rollers engage either the fountain roller or the ink or water applying rollers, thus permitting of a dwell. The rollers 35, 55 are similarly mounted in upper frames or yokes 37, 57, which are connected to lower pivoted frames 38, 59 by means of central vertical pivots which permit the rollers 35, 55 to swivel about a vertical axis and to engage their rollers with true line contact. The fountain roller 32 is intermittently rotated at each operation of the machine, the extent of its rotation being controlled by an adjustable guard 120 which controls the action of an oscillating pawl engaging a ratchet 119 on the shaft of the roller 32. Either or both of the applying rollers 62, 34 can be put out of action by means of a rotary cam-shaft 150 which can be rotated by hand and is set by the aid of a pointer 152 and scale 153. On rotating this shaft from the position shown in Fig. 3, in which both rollers are in operation, a cam 154 acts on an exension of a pivoted frame 65 in which the roller 62 is mounted and the frame is moved against spring action to trip the roller 62. A further rotation causes a cam 146, Fig. 3, to operate a lever 148, and a link 157 which acts on an extension of the frame 42 to trip the roller 34. On further rotation of the shaft 150, the roller 62 comes into action and finally both rollers 34, 62 are restored to active position.

Filed: 1937-04-02
Abstract: 493,116. Electrical precipitation apparatus. LODGE-COTTRELL, Ltd. (International Precipitation Co., Inc.) April 2, 1937, No. 9399. [Class 39 (i)] The provision for jarring the electrodes to assist the removal of deposits, consists in mounting the electrodes so as to be capable of a rocking or oscillatory movement in a vertical plane, and in providing a number of anvil members arranged to impart a succession of blows at different points of the electrodes when they are displaced from their position of rest and suddenly released. In the construction shown in Fig. 1, the collecting electrode 1 is suspended by a flexible strap 8 and springs 17, 28. A bar 46 carried on the end of a crank-arm 48 of the rock-shaft 49 acts periodically through the yoke member 50 and strap 37 to lift the electrode and release it allowing it to fall under the action 'of gravity and the supporting springs. In the return movement, a buffer 35 on the electrode contacts with a stop 36. The contacting surfaces are curved so that the electrode swings around their point of contact bringing the stop 34 and anvil 33 into contact. The reaction brings the upper corners of the electrode into contact successively with the anvil 21 and the adjustable stop 19. Buffer springs 31 may be provided to modify the contact between the stops and anvils. The shaft 49 is preferably actuated by a solenoid and automatically controlled time relay or manually. The electrodes may be of the tubular type. A modification is described in which the collecting electrode is suspended by a lever which is actuated by a rotating snail cam. Adjustable anvil plates are disposed to be engaged by the top and bottom corners of the electrode in succession. One of the anvils is preferably actuated by a crank on a shaft rotating at a speed different from the cam-shaft so as to vary the percussive effect on the electrode. Fig. 6 shows the application to a discharge electrode system comprising wires stretched on a frame 80. The top bar 81 is suspended by a link 83 from an insulated support 84. Stops 85, 86 are provided at the top and bottom of the side bar 81<1> of the frame. A rotating snail cam 87 and an anvil 88 are mounted in insulators 90. In a modification the link 83 may be replaced by a plate carrying a roller running on a curved guide fixed to the stationary structure. Specification 444,660 is referred to.

Abstract: 1292267 Programmed control of machine tools WERKZEUGMASCHINENKOMBINAT "FRITZ HECKERT" KARL MARX STADT VEB 27 Feb 1970 9622/70 Heading G3N A programme control machine tool system is modified to optimise the use of the machine tool by superimposing on the control of the rate of advance of the tool along the workpiece a control dependent on the depth of cut. The modification being arranged to reduce the depth of cut when the rate of advance falls to a minimum, due to overload, to increase the depth of cut when the rate of advance reaches a maximum, due to underload, and, when a minimum use of the cutting system is not attained at an upper value of the rate of advance, the present programmed cut is discontinued and a new cut initiated which is increased in depth provided that the depth of cut was not reduced in the preceding cut. Facilities are provided whereby towards the end of a programmed cut the rate of advance of the tool is reduced in overload and change in the depth of cut only initiated after a predetermined distance from the start of a programmed cut. The modification is carried out by relays, controlling the rate of tool advance and depth of cut, energized through contacts, selectively actuated in AND-logic, when the tool load is outside of a predetermined range. Additional contacts are operated by times or spindle counters to prevent modification within predetermined times, or distances from, the beginning and end of a programmed cut.

Title: Improvements in and relating to the manufacture of lubricating greases
Inventor: MATTHEWS JOHN BRYANT
IPC: G03F7/18
Filed: 1950-04-20
Abstract: Lubricating grease comprising an oleaginous vehicle and a lithium soap of a hydroxy-substituted higher saturated fatty acid, or a mixture of this soap with a lithium soap of a higher saturated fatty acid, is made by heating the ingredients until a homogenous composition is formed, slowly cooling to a temperature not higher than and not more than 40 DEG C lower than its single critical phase transformation point, isothermally gelling the composition at this temperature and finally cooling and homogenizing the gel.  Higher fatty acids are those of formula CnH2n COOH where n is greater than 12.  Hydroxy fatty acids specified are 9-, 10-, 11-, 12- and 13-hydroxystearic acids, 10-and 15-hydroxypalmitic acids, 1-hydroxy myristic acid and phellonic acid.  Polyhydroxy acids mentioned are 5.6-, 6.7-, 7.8-, 8.11-, 9.10- and 10.11-dihydroxystearic acids, 2.11-dihydroxypalmitic acid, ipurolic acid and sativic acid. Fatty acids referred to are stearic, myristic, palmitic, margaric and behenic acids.  Soaps such as lithium, sodium or aluminium naphthenate and sodium, aluminium or calcium stearate or palmitate may also be present in the composition.  The oleaginous vehicle may be a mineral lubricating oil, a synthetic oil such as that obtained from the Fischer-Tropsch process or from the condensation of polymerized unsaturated hydrocarbons with aromatic hydrocarbons, or an ester synthetic lubricant such as dioctyl sebacate.  Antioxidants such as 2, 4-dimethyl-6-tertiarybutylphenol, 2,4-dimethyl-6-tertiary octyl phenol, phenylene diamines and phenyl-beta-naphthylamine, extreme pressure agents such as sulphurized olefines and oleic acid, and anti-corrosion agents may also be added to the composition.  In an example, mineral lubricating oil and a soap mixture consisting of 20 per cent lithium stearate and 80 per cent lithium 12-hydroxy stearate are mixed together at 210 DEG C. and then cooled to 110 DEG -150 DEG C. at a rate of about 2 DEG C. per minute.  The grease is kept at this temperature for 2 hours, cooled rapidly to room temperature and then milled.

[Also in Division B3] In a multi-drilling machine each of the tools 4 passes through a loop 3 containing a pair of coils 5, 6, and completes a magnetic coupling, but if one of the tools is broken the coupling is not made, a signal lamp 16 is lit, and the machine is stopped. A pair of loops 3 is fixed on the machine, and tools 4 extend through the loop 5. Primary coils 5 are connected in series to an oscillator 9, powered by a D.C. power unit 10, from A.C. mains 11, and secondary coils 6 form a pair of arms of an A.C. bridge circuit, the other arms of which are formed by a potentiometer 12. The output from the bridge circuit is amplified at 14, to control a relay 15 which lights signal lamp 16, and operates a contactor 17, to stop the machine tool. Coils 5 are energized only when the tools are fully withdrawn and switch 13 is closed by the tool carriage. If a tool is broken the coupling between coils 5 and 6 is reduced, the bridge circuit is unbalanced and lamp 16 is lit, and the machine is stopped. A number of pairs of loops may be used, and in the case of a single tool to be tested, a dummy loop is used.

Title: Integrated sense amplifier circuit
Inventor: KRAUS RAINER DIPL-PHYS
IPC: H03K5/02
Filed: 1993-09-30
Abstract: An integrable evaluating circuit includes a trigger circuit, a first and a second circuit node, both of which serve both as inputs and as mutually-complementary outputs for the trigger circuit, a pair of signal lines exhibiting the same potential in a rest state, switching transistors each being connected between a respective one of the two circuit nodes and a respective signal line of the pair of signal lines, and a signal-enhancement circuit connected between the trigger circuit and the pair of signal lines. A signal occurring on a given one of the two signal lines is initially connected with its signal deviation to the circuit node connected to the given signal line. The switching transistor connected to the given one of the two signal lines is then blocked and cuts off the signal from the circuit node connected to the given signal line. The signal-enhancement circuit then increases the potential at the circuit node connected to the given signal line by a given amount while simultaneously reducing the potential at the other of the two circuit nodes as a result of potential shift. The potential of the circuit node connected to the given signal line is reduced and the potential of the other of the two circuit nodes is increased if the signal has a negative signal deviation.
