Abstract: 1,143,068. Applying lubricating finish to polyester filaments. E. I. DU PONT DE NEMOURS & CO. 22 March, 1967 [25 March, 1966], No. 13471/67. Heading B5B. Melt spun polyester filaments are lubricated by contacting them with a lubricating and antistatic finish in three stages, the concentration of the finish differing in each stage. In the first stage the quenched melt-spun filaments are converged to form a yarn and there is applied to the yarn a finish composition of ionic and non- ionic components in moderately dilute aqueous emulsion. In the second stage the treated filaments are collected and passed to a draw zone in which they are drawn and aqueous finish emulsion less concentrated than the first is applied to them. The drawn filaments are then passed to a crimping zone in which they are crimped. In the third stage an aqueous finish emulsion more concentrated with regard to the finish composition than the first emulsion is applied to the crimped filaments. The finish consists essentially of a condensate of a fatty alcohol or fatty acid having 12 to 18 carbon atoms in its alkyl chain and 9 to 25 mols of ethylene oxide per mol of fatty alcohol or fatty acid and a salt of a partial ester of orthophosphoric acid and an alcohol containing 8 to 18 carbon atoms. The crimped filaments may be heated in a relaxed state prior to the application of the concentrated aqueous emulsion finish. The first stage emulsion may contain about 0À50% of active finish components, the second stage emulsion about 0À25% of active finish and the third stage emulsion about 15% of active finish. The fatty acid condensed with the ethylene oxide may be lauric acid.

Title: Improvements in control systems for x-ray tubes
IPC: H05G1/46
Filed: 1941-10-27
Abstract: 555,331. Control systems for space discharge apparatus. GOLDFIELD, E. R., and GRAVES, E. B. Oct. 27, 1941, No. 13796. [Class 38 (iv)] To prevent an X-ray tube being operated for a long period at a heavy load the timer and output control means operate co-ordinated switches in a circuit controlling tube energization. An output adjusting switch 22 controlling filament current is coupled to a selector switch 33 which puts different portions of the control circuit in series with a coil 28. The energization of this coil starts the tube. Switches D, E in these circuit portions are opened in succession as the timer (which opens a switch B after the period set) is progressively adjusted from its minimum exposure position and vice versa, and a switch C is opened when the rate of movement of the timer is changed from high to low speed ; the starting circuit through the manual switch 36 is thus complete only when the load setting is a minimum (as shown) if the timer is set to a maximum exposure and the maximum load can only be used with a minimum exposure, with suitable intermediate correlated settings. The switches D and E are independently adjustable in relation to the timing knob. A construction is described of a suitably modified timer of the type in which a motor rotates an actuator, for opening a switch B through an adjustable distance at one of two selected speeds by a friction clutch engaged by energization of coil 28.

Filed: 1962-04-10
Abstract: 951,852. Diode switching circuits; transistor bi-stable circuits. ING. C. OLIVETTI & C. S.p.A. April 10, 1962 [March 26, 1962], No. 13808/62. Headings H3P and H3T. A circuit for producing pulses in one sense or the other across the secondary 11 of a transformer, in which the primary of the transformer comprises two sections 13, 14 having a different number of turns is characterized in that one terminal of both sections is connected to a pulse generator 20, and the other terminal of the major section 13 is connected through a diode 17 to a source of binary signals 19, the arrangement being such that a current pulse from the pulse generator 20 flows through one or both primary windings under the control of the binary signal. As described, the circuit is used for switching a transistor bi-stable circuit FF to one or other of its states, corresponding to a binary " 0 " or " 1." Thus when a binary " 1 " is to be stored diode 17 is cut off by a signal from source 19, and the current pulse from source 20 passes only through winding 14 inducing a pulse in the secondary suitable to drive terminal 7 in order to set the bi-stable circuit in its " 1 " state. Conversely when a " 0 " is to be stored diode 17 is rendered conducting and a pulse of opposite polarity is induced in the secondary of the transformer.

Filed: 1947-05-27
Abstract: 631,361. Variable-speed ratchet gearing. KOLKO, A. May 27,1947, Nos, 14072 and 14073. Convention dates, June 6, 1946 and May 21, 1947. [Classes 80 (ii) and 80 (iii)] In ratchet gearing in which the motion of the driving shaft is transmitted by a plurality of connecting rods, the driving and driven shafts are coaxial, the driving crank is resiliently loaded to the position of maximum eccentricity and the connecting rods extend radially to connect through centrifugally controlled ratchet mechanisms to layshafts parallel to the driven shaft and connected thereto by gearing. A hollow driving shaft 1 carries a crankpin 3 connected to a second crank 4 having a crankpin 5, the crankpin 3 being connected by a pinion 9 to a gear portion of a torsion bar 6 anchored by a vernier coupling 10 to resiliently urge the crankpin 5 to its position of greatest throw. The crankpin 5 carries a rotatable hub 11 to which are articulated three double connecting rods 13 pivotally connected to the crossheads 14 pivoted about the layshafts 15. The crossheads 14 are coupled by pawls 19 to ratchet wheels 17, rigid with the layshafts 15 and with the gears 20, meshing with a pinion 21 on the driven shaft. The pawls 19 have counterweights attached in a plane passing through their axes and the axes of the layshafts 15 so that the centrifugal force on the counterweights, as the crossheads 14 rotate, causes the pawls to be held in the engaged or disengaged positions, which position being determined by the tangential forces at the ends of the strokes. The end of the driven shaft is supported by rings 22 rigid with the gears 20 which bear on a ring 23 rigid with the driven shaft, the diameters of the rings being equal to the pitch circle of the intermeshing gears. By virtue of the spring loading of the crank 5 the transmission ratio is determined by the resisting torque ; when the ratio is unity or tends to be greater than unity the casing carrying the layshafts is held stationary. In a modification, Fig. 7, a pawl and ratchet mechanism is used to prevent backward rotation of the gear casing, the pawls 29 being lightly loaded by the springs 31 to engage with the toothed ring 30 rigid with the outer casing of the transmission, the pawls 29 being pivoted on the layshafts 15 and having their outer ends arranged to have a braking effect on the outer casing when in the engaged position.

Abstract: 1423000 Vehicle harness reels SOC ANON FRANCAISE DU FERODO 23 March 1973 [20 March 1973] 14225/73 Heading A3V A vehicle safety belt reel comprises a frame in the form of a plate 10 having side flanges 12, 13 housing a rotary shaft 16 to which one end of the belt (not shown) is attached, the shaft 16 being subjected to the action of a return spring 28 tending to wind in the belt, and a wheel 50 mounted on the shaft 16 for rotation therewith and for axial movement relative thereto, the wheel, having thereon locking teeth 54 for cooperation with teeth 41 on the flange 12 so as to lock the reel against belt withdrawal, a pivotally mounted finger 46 being interposed between the wheel 50 and flange 12 to hold the teeth 54, 41 out of engagement against the action of a spring 58 during initial belt withdrawal, subsequent relaxation in the tension of the withdrawn belt allowing cam teeth 55 on the wheel 50 to push the finger 46 clear of the wheel allowing it to move axially and causing mutual engagement between the teeth 54, 41 to lock the reel. The cam teeth 55 allow rotation of the shaft 16 in the direction of belt withdrawal without displacement of the finger 46 from the position shown in Figure 3 into which it is urged by a spring 47, but rotation in the opposite direction causes the faces 70 of the cam teeth to engage the face 71 of the finger 46 to pivot it clear of the wheel 50. An extension 21 of the shaft 16 is screw-threaded and mounted thereon is a non-rotating nut 56 which therefore moves axially on the extension 21 as the belt is wound-in and withdrawn and serves to draw the wheel teeth 54 clear of the fixed teeth 41 by engagement with a flange 57 to unlock the reel when the belt is nearly wound in. In an alternative embodiment (not shown) the wheel 50 is coupled to a manually withdrawable button projecting outside the reel housing to unlock the reel when desired, the button further being rotatable through an arc to lock the shaft 16 against rotation in either direction.
