Title: Improvements in or relating to button hole sewing machines
IPC: D05B3/08
Filed: 1944-05-24
Abstract: 586,162. Buttonhole sewing-machines. NEWTON, E. P. (International Button Hole Sewing Machine Co.). May 24, 1944, No. 10072. [Class 112] Thread-end holders. A thread pick-up device which engages the thread between work and needle after it has been severed and holds the loose end clear of the clamp is actuated by the return movement of a lever carrying the buttonhole cutter. In the arrangement shown, the finger 71, Fig. 5, which has a hooked end with an insert of felt, is adjustably fixed to a spring- biassed arm 74 pivoted at 78 to the needle-bar guide. The lever 51 carrying the buttonhole cutter 50 has a pivoted spring-biassed detent 82 which wipes past the end 81 of the arm 74 on its downward stroke but engages it on its upward stroke to move the finger 71 to the threadengaging position as shown, further movement releasing the arm to return to the dotted position. Stopping and starting. The machine is driven by a belt 30, Fig. 3, engaging fast and loose pulleys under the control of a member 33 carried by an arm 34 which is pressed down by a spring plunger 45 and is fixed to a rock-shaft 35 slidable longitudinally by the control treadle against a spring. A member 41, slidable on the stop-arm 34 against a buffer spring 42, has a nose 43 engaging a cam 44 on the machine shaft when the belt is on the loose pulley, so that just before the machine stops the arm 34 is raised by the surface b and then drops to engage the stop surface d, the shock of stopping being taken by the spring 42. A stud 57 on the stop-arm 34 is connected to the buttonhole cutter lever 51, so that the rise and fall of the arm on stopping operates the cutter. A lug 67 on the member 41 engages a notch in a sliding member 63 when the stop-arm falls, so that the movement of the member 41 in taking up the shock of stopping oscillates a rock-shaft 61 which has at its other end an arm engaging a sliding stitch-setting and thread-cutting member; the thread is thus cut almost simultaneously with the operation of the pick-up arm 74.

Title: Process for obtaining high grade cellulose from soiled and disintegrated vegetable fibres, particularly from cotton wastes such as linters, hull fibre and spinning mill wastes
IPC: D21C5/00
Filed: 1930-04-01
Abstract: 347,444. Cellulose. KAMMERL, H., 19A, Aachenerstrasse, D³ren, Rhineland, Germany. April 1, 1930, No. 10345. Convention date, Nov. 12, 1929. [Class 96.] In the preparation of high grade cellulose from cotton wastes such as linters, hull fibre and spinning mill wastes, the greatest part of the impurities is first separated by the use of a sieveless centrifuge after which the pectins, waxes and fats embedded in the fibres are dissolved out by bucking or gentle boiling. The consumption of chemicals used in the process is thus considerably reduced and the loss in yield of cellulose associated with prolonged boiling operations is avoided. In an example described, waste linters containing 23-5 per cent of non-cellulosic material are beaten up with water in a hollander and then run through a sieveless centrifuge. The separated cellulose material containing 4-8 per cent dry non-cellulosic material is treated for 1 hour at 80‹ C. with a 1 per cent alkaline soap solution, then washed and bleached with calcium hypochlorite solution.

Title: A self-priming centrifugal pump, more particularly for impure liquids
IPC: F04D9/02
Filed: 1957-03-29
Abstract: 849,449. Centrifugal pumps. SIGMA LUTIN NARODNI PODNIK. March 29, 1957 [March 29, 1956], No. 10355/57. Class 110 (1). A self-priming centrifugal pump comprises at least three spirals formed within the pump casing, the leading edge 3 of the first spiral having only a small clearance from the periphery of the impeller and the leading edges 8, 7 of the succeeding spirals having an increasing clearance from the periphery. Before starting, the chamber 12 is filled with liquid. When the pump is running, a circulating flow is created inside spiral passages 2, 5, 6, resulting in a flow through the spiral 6 of a mixture of the liquid and air or other gas drawn in through the suction passage 13. The air or other gas is separated from the liquid in the chamber 12 and escapes to atmosphere. When the liquid to be pumped has risen in the suction pipe until it fills the suction passage 13, priming is completed. The spiral passages 2, 5, 6 are of unequal areas at their discharge ends. The chamber 12 may be of rectangular, circular or oval cross-section. The impeller may be shrouded and may have more than two blades. The pump shaft may be vertical instead of horizontal, the chamber 12 and the exit ends of the spiral passages, 2, 5 and 6 being turned upwardly from the horizontal to the vertical.

Title: Improvements relating to automatic gas ignition apparatus
IPC: F23Q7/10
Filed: 1943-06-28
Abstract: 566,539. Valves. RADIATION, Ltd., and WASS, N. H. June 28, 1943, No. 10437. [Class 135] [Also in Group XXXVII] A switch for controlling the automatic ignition of gas and operating in response to the gas-pressure, is closed preparatory to, and opened in response to, each opening movement of the valve controlling the gas-supply, ignition being effected by a heating coil which ignites a pilot burner for the main burner. The gasinlet g communicates with the outlet j via chambers c, d and a passage i normally closed by a valve k on a diaphragm m. A chamber e above the letter communicates with chamber c through an annular passage u surrounding the stem'p in the valve-bore q. When gas is first supplied to chamber c, a diaphragm o lowers contact r on stem p to engage contact s and energize the heater coil of the pilot jet, which is simultaneously supplied with gas through passage u and chamber e. Gas is then admitted by inlet w to chamber d and outlet j for the main burner, the valve k being thus lifted to supply d direct, and, by engaging shoulder v on stem p to open contact r and cut off the pilot supply. A three-way control tap, Fig. 3, comprises, in addition to the normal throughpassages 4 a connection 5 for simultaneously supplying the byepass w, as shown by the dotted position of the plug 3, the latter being restored by a spring (not shown) to the straightthrough position.

Title: Improvements in or relating to twin lens photographic cameras
IPC: G03B13/20
Filed: 1940-06-20
Abstract: 536,195. Twin lens photographic cameras. KODAK, Ltd. June 20, 1940, No. 10614. Convention date, Sept. 7, 1939. [Classes 97 (i) and 98 (i)] In a twin lens camera, means actuated by focusing the objective simultaneously focuses the finder lens 42 and alters the inclination of the mirror 41 by which the image is reflected on to a ground glass screen 40 to correct for parallax. As shown, the same means also adjusts the movable element of a range-finder. The objective shown is carried by a focusing mount of the kind described in Specification 530,429, which is secured by a rotatable threaded adapter 24 engaging in a threaded ring 25 carried by the camera front, and is provided with a rotatable focusing ring 28 in threaded engagement with a carrier 29 for the lenses. The rear edge of the ring 28 is toothed to engage a toothed ring 34 which is rotated on ballbearings 36 through gears by a focusing knob in order to rotate the focusing ring 28. The ring 28 has a shoulder 31 formed as an axial cam with which engages a wheel 61 carried by a forwardly projecting arm 60 on a carriage 54 slidably mounted by a pin-and-slot connection 56, 57 on a plate 51, and urged forwardly by springs 62. The movements of the carriage produced by the cam 31 on rotation of the focusing ring are transmitted to the finder lens 42 by two arms 55 which extend upwardly from the carriage and engage pins 58 which project from a slidably mounted sleeve 46 into which a carrier 45 for the lens elements is screwed The sleeve 46 is carried by ball-bearings in a guidetube 47, the pins 58 extending through slots in the ball-cage 49 and the tube 47. The inclination of the mirror 41, which is mounted on a plate carried on pivots 68, is adjusted to compensate for parallax by the movement of pins 72 carried by the arms 55 in slotted arms 70 extending forwardly from the carrying-plate. The range-finder comprises fixed and rotatable prisms 75, 76 in front of which are lenses 81, 82, the image-forming beams being directed to two prisms 77, 78 and thence to a prism 79 which renders the images visible through a clear glass area 80 in the ground glass 40. The prism 76 is carried by a rotatable rod on the lower end of which is a cam-arm 88 which is engaged by a pin 89 on the carriage 54, the prism 76 being thus rocked as the carriage moves. When the object is too close for accurate focusing by the range-finder, the pin reaches a break 93 in the cam surface, which causes the range-finder images to be thrown out of coincidence, thus warning the operator that the distance should be measured and the objective focused by hand accordingly.

Abstract: 777,341. Waveguide accessories. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and BUCKINGHAM, J. March 22, 1955 [April 13, 1954], No. 10904/54. Class 40 (8). [Also in Group XL (c)] A microwave channel of variable electrical length comprises a magnetically polarized length of material exhibiting ferromagnetic resonance through which an electromagnetic wave may be propagated in an E mode, the length of material having at either end mode transformers for transforming the E mode to and from an H mode. The ferromagnetic element may be in the form of a ferrite rod F, Fig. 3, surrounded by a coaxial solenoid MC to which a variable current may be applied. Energy in the H11 mode is fed to and extracted from the element F by waveguides WG1, WG2 transformation between the H mode in the guides and the E mode in the element being effected by probes P1, P2. With this arrangement the flux density due to the axial applied magnetic field and the R.F. magnetic field within the element F will be at right angles to each other and as a result of the gyromagnetic effect, the effective R.F. permeability (eff.Á) of the ferrite will vary with the applied field. The wavelength of the propagated energy in the ferrite is given by #= 1f#eff.Á.K (where K is the dielectric constant) so that large changes in A may be obtained by varying the applied field. In order to obtain satisfactory values flux density and hence of eff. Á, the ferrite element F should have a high length to diameter ratio. The output waveguide WG2 may be replaced by a reflecting plate (Fig. 4, not shown), whereby the wave energy traverses the element F once in either direction and returns to the input guide WG1. In the construction of Fig. 5 transformation between the E and H modes is achieved by tapered end portions of the element F, these portions being several wavelengths long. Impedance matching between the guides WG1, WG2 and the element F may be imposed by arranging or winding the solenoid MC so that the magnetic field diminishes in intensity at one or both ends of the element. In this construction the output guide WG2 may be replaced by a reflector (Fig. 6, not shown).
