Title: Improvements in or relating to printing machines
IPC: B41J2/30
Filed: 1956-11-30
Abstract: 805,569. Copying-telegraphy. COMPAGNIE DES MACHINES BULL. Nov. 30, 1956 [Dec. 14, 1955], No. 36754/56. Class 40 (3). A cyclically-operated printing machine in which characters are formed by elements or dots printed by devices IMP-1, IMP-2, &c., each comprising five electromagnets A1-A5, connectable to a pulse generator PG formed by notched discs GA, GB, &c., and to a commutator DS which during a machine cycle successively connects the appropriate electromagnet into circuit. The pulse generator PG comprises one disc for each character and rotates once in each cycle. The disc GA has a sector 12, raised portions SA1, SA2, SA3, which make contact with a brush BA and if a letter A is to be printed relay contacts R11-8b are closed so that the pulses from positive is directed through the generator to line LC1, patch-cord CF, and through that electromagnet A1-A5 which has a path to negative through the commutator DS. During the time it takes the commutator DS to move from one constant to another, e.g. in the case of A, from C2 to C3 and C4 the paper is advanced an amount corresponding to the displacement in direction F1 of the printing elements F2-F4. The result is that the dots PT1, PT2, PT3 are printed in a horizontal line. The next section (13) of disc GA has raised portions at the first and fifth positions so that dots PT4 and PT5 are formed during passage of arm R of commutator DS over contacts C1 and C5. This process occurs for each of the seven rows of the character until the whole character is formed. The operating contacts R11-8b may be operated by a decoding device operated by punched cards. Each column of the card, Fig. 5, having eleven positions; figures being represented by a single perforation, and letters by a perforation in position 11-0-1 ... 6 and a perforation in position 7, 8 or 9. Specification 425,883, [Group XL], is referred to.

Abstract: 859,719. Regulating liquid levels. VALOR CO. Ltd. Oct. 13, 1959 [Nov. 15, 1958], No. 36825/58. Class 123(1) [Also in Group XI] A liquid fuel burner for a heater is fed from a fuel container 3 which may be in the form of a clear glass bottle with a coaxial neck 4 provided with an outlet valve 5. The base 6 of the container is convexly curved on the inside to form a dome 7 which at least around its crown 8 is transparent, the crown being in the centre of the base. On the outer surface of the base is an index which may be a ring or a circular rib 9, the centre of which is axially aligned with a crown 8. When the container is inverted and put into the heater, the dome is above the free surface of the fuel in the container and the mounting disposes the dome so that its crown 8 is the nearest part of the dome to the datum plane 20. Fuel still wetting the dome gravitates to the lowest part of the dome where it forms a globule 22. The feet 21 are adjusted until the globule 22 is concentric with the circular rib 9. The globule is then at the crown and the datum plane is horizontal.

Title: Second sound measurement of rotational motion
IPC: G01P3/44
Filed: 1969-07-23
Abstract: 1,224,585. Wave-energy measurement of rotation. HARVEST QUEEN MILL & ELEVATOR CO. 23 July, 1969, No. 37127/69. Heading H4D. Motion of a housing, containing a superfluid, relative to a fixed reference is sensed by producing two oppositely-directed beams of "second sound" (entropy) waves in the superfluid and detecting any phase difference changes between the beams as received at a detector station. In the embodiment shown a cylindrical housing 10 is rotatable relative to fixed reference surface 12 and contains liquid helium II at 0À5 to 2À2‹ K. The helium is considered to have a superfluid component and a normal fluid component. By energizing a shielded carbon resistance heater 18 from a 100 kHz source 22, a "second sound" wave is propagated in which the superfluid component collects at points of low temperature and the normal fluid component collects at points of high temperature half a wavelength away. This wave is divided by beam splitter 24a, 24b into a first beam which is reflected at 26 to detection point 28 and thence through window 30 for absorption, and a second beam which is reflected at 32 to detection point 34 and thence through window 36 for absorption. Providing the cylinder 10 rotation rate is below a critical value, the superfluid helium will not rotate with the cylinder and the rotation will introduce a change in the phase difference between signals from thermocouples at detection points 28, 34. This change is sensed by amplifier 38 which drives a servo loop system 16, 14 for modifying the rotation to nullify the phase difference change. Reference surface 12 may be part of a space vehicle.

Abstract: <PICT:0426702/IV/1> <PICT:0426702/IV/2> <PICT:0426702/IV/3> <PICT:0426702/IV/4> In a warp-sizing machine which is driven either through a low-speed over-running clutch 14 or through a high-speed clutch 7 under the control of a lever 26 as described in Specification 421,948, [Group IX], the lever 26, when moved from position II, Fig. 3, to disengage the clutch 7 through a rod 25, opens a spring - closed switch 24 in the circuit of a solenoid 33 controlling the forward-running switch 31 of the driving motor 23. The core 32 of the solenoid 33 is connected by a lever 34, Fig. 11, with the core 32<a> of another solenoid 33<a> in circuit with a hand switch 36 and controlling the reverse-running switch 31<a> of the motor 23.  The closing of the switch 36 can therefore only effect the reversal of the machine if the circuit of the solenoid 33 is open, i.e. if the high-speed clutch 7 is out of gear.  As shown in Fig. 12, the switch 24 closes the circuit of solenoid 33 or 33<a> according as the clutch 7 is in or out of gear.  A hand switch 36<a> completes whichever solenoid circuit is closed by the switch 4.  The take-up 3, Fig. 1, and the drying cans 2 are driven directly by the means described, and the quetch rolls 38 are driven from the first can by positive gearing at a reduced speed so that the warp a is positively and uniformly stretched, and this gearing is preferably of the variable-speed type.  The gearing shown in Fig. 9 comprises a pinion 52 slidable on a shaft 50 which gears with another pinion 54 which can be made to engage with any of several wheels 56 of different sizes on a shaft 55.  This shaft 55 is geared with the quetch rolls through a reversing gear 57, 58.  The upper two rolls 38, Fig. 7, of the quetch can be lifted by means of screws 40 and <PICT:0426702/IV/5> <PICT:0426702/IV/6> a hand wheel 45, the pressure of the rolls on the warp being indicated by a pointer 47 on the shaft 44 of the wheel 45 and a dial 48.

Title: Improvements in mechanism for controlling the speed and direction of movement of machine-tool elements
IPC: B23Q5/54
Filed: 1957-12-09
Abstract: 850,399. Machine-tool details; boring-mills. WARNER & SWASEY CO. Dec. 9,1957 [Dec. 14, 1956], No. 38221/57. Class 83 (3). An arrangement for controlling the speed and direction of movement of a machine-tool element such as a slide, includes a single lever which operates through switch-means and a control-circuit. A boring and turning-mill with a rotating work-table 11, Fig. 1, and toolslides D, D<1>, vertically-movable on horizontallyadjustable carriages C, C<1>, respectively, has a control-panel 24 carrying single lever-control members 26, 27, for the direction and speed of movement of the tool-slides. The levers are identical and one only is described. Each lever controls a pair of hydraulic motors, e.g. 14, 20, which, through lead-screws 16, 21, respectively, move the two slides for the tool T. The lever 26, Fig. 2, is secured to a ball-member 65 which moves within a socket 48. A stem 69, secured to the lower part of the ball-member, carries a mushroom-shaped cam-piece 68. The stem 69 moves in a cruciform " gate " 67 forming part of the support 48. The latter may be turned, and held in a position at 45 degrees to the normal position, by spring-pressed balls 57 for a purpose described below. The lever 26 is held in the neutral (vertical) position by radial spring- pressed plungers 70. When the lever is moved away from the neutral position in one of the planes represented by the cruciform " gate," the tool is moved in a corresponding direction and at a speed in accordance with the displacement of the lever. If the support 48 is moved to a position at 45 degrees, movement of the lever then operates two slides simultaneously and the tool moves angularly. The cam 68 operates switches 76-79, Figs. 2 and 5, these closing in the positions of the lever when the switch-rollers 75 &c. move over the edge of the cam. A spring-pressed plunger 80 also contacts the cam, the mushroom surface of which moves the plunger to which is connected core 90 of a differential-transformer for effecting the feed control. This is obtained through a controlcircuit which finally passes current to a pair of torque-motors operating valves for the hydraulic motors 14, 20. A further switch 87, Fig. 2, is provided so that when the plunger 80 is depressed by the cam to its maximum extent, a rapid traverse is obtained for the tool slide. The control-circuit is adapted selectively to correlate the speed of the work-spindle and a tool slide. Specification 850,400 is referred to.
