Title: Improvements in and relating to a method and a machine for cleaning strip or filament materials
IPC: B08B1/02
Filed: 1958-07-31
Abstract: 829,053. Cleaning strip &c. materials. DOMINEL. Jan. 31, 1958 [Feb. 13, 1957], No. 3239/58. Class 99(2). In a method of cleaning and degreasing strips or filaments of material, particularly metal bands, by means of at least one rotary brush, the brushing operation is effected in a chamber into which divided material is introduced and discharged in a continuous or intermittent manner ; the material is subjected to agitation in the chamber so as to form a cloud in which the brushing operation is effected. As shown, the cleaning apparatus comprises brushing and washing units 8, 9 and 10, each unit consisting of a cylindrical drum 11 having sides 12 and 14 formed of two fixed outer parts 15, 17 and two movable inner parts 16, 18. The drums of the units 8, 9 each have an opening 19 for the reception of a hopper 20 adapted to feed sawdust, sand, lime or powdered detergents into the drum. The wall 13 of the latter has lateral openings 21 provided at the edges thereof with flexible or resilient blades 22 forming sealing and wiping devices for the band, and a lower opening 24 for the discharge of the sawdust into a tray 25. Rotatably mounted in each drum 11 are two parallel and spaced apart spindles 30, 31 carrying annular brushes 32, 33 of wire or plastic material such as nylon, and spindles 35 carrying beaters 36 constituted by rectangular-bladed wheels. The spindles 30, 31 carry gears 37, 38 which mesh with a gear 40 freely rotative on a fixed shaft 41, and the spindles 35 carry gears 39 meshing with one another, the gear 39 located in the vertical axial plane of the drum being rigid with a sprocket 42 connected by a chain 44 to a sprocket 43 secured to the gear 40 and a sprocket 45 driven by an electric motor 47, the latter also drives a sprocket connected by a chain 51 to all the units of the apparatus. Due to angular displacement of the parts 16, 18 relative to the fixed parts 15, 17 the brushes may be moved from a position on the vertical axial plane of the drum to a second position to compensate for wear of the brushes. The washing unit 10 comprises only brushes the lower of which is constantly immersed in water in a bath 59. Bars 62 supporting guide pins 63, and pairs of guide rollers 64 facilitate feeding of the bands to the units, and return of the bands from the unit 9 to the unit 8 for a further cleaning cycle is effected by devices 65, 66.

Filed: 1937-02-04
Abstract: 489,385. Retractable undercarriages for aircraft. WILLOUGHBY, P. N., and WILLOUGHBY DELTA CO., Ltd. Feb. 4, 1937, No. 3351. [Class 4] A retractable aircraft undercarriage primarily for use with high-wing monoplanes comprises two similar parallel arrangements of hinged struts mutually connected so as to be laterally rigid and each consisting of three struts constituting a three-bar linkage hinged at its spaced upper ends to fixed parts of the aircraft and adapted to be stabilized by a fourth strut of which one end is slidable along one of the three struts from a position in which the linkage is indeformable to a position in which it is deformable to effect retraction, a shockabsorbing strut and a radius rod both connected to a wheel-carrying axle being hinged to intermediate joints of the linkage. In one form, Figs. 1 and 4, the three-bar linkages each comprise a strut 4 pivoted at 7 adjacent the front spar of wing 1, a strut 13 pivoted at 14 to the lower ends of rigid members 15 depending from wing 1, and a strut 10 pivotally connected to struts 4 and 13, a stabilizing strut 16 being pivoted to the structure at 14a at one end and at the other to a member 17 slidable along strut 10 under the control of an endless cable 18 passing over pulleys disposed at the pivots of the linkage. A wheel 8 is carried by an axle 9 mounted between the ends of shockabsorber struts 5 pivotally mounted on a spindle 6 interconnecting struts 4 and 10, and also between the ends of radius rods 12 pivoted on spindle 11 interconnecting struts 10 and 13. A cable 23 attached to axle 9 serves to retract the undercarriage after collapse of the linkage has been effected by actuation of cables 18. Cables 18 may be wound in by an electric motor automatically set in motion after a predetermined amount of movement of sliders 17, the motor being switched off when the wheel axle or some other part of the undercarriage engages a spring retaining catch. Extension is initially effected under the action of gravity by manual release of the catch and is completed by actuation of cables 18 to move the struts 16 into the locking position against stops 25. In a modification, Fig. 6, providing for rearward retraction of the wheel, the three-bar linkages comprise struts 29, 32, 33 adapted to be stabilized by struts 37 connected to members 39 slidable on struts 32, and are pivotally attached at their upper ends to lugs provided on supporting members 28, 36 disposed within an engine nacelle 3. Radius rods 31 extend rearwardly from spindle 30 interconnecting struts 29, 32 and shock-absorber struts 26 are pivotally mounted on lugs provided on supports 28. The retracting means are similar to those above described.

Title: Lung ventilator
IPC: A61M16/00
Filed: 1971-02-02
Abstract: 1384534 Respiratory appliances BRITISH OXYGEN CO Ltd 2 Feb 1972 [2 Feb 1971] 3740/71 Heading AST A lung ventilator is switched from an inspiratory mode to an expiratory mode when a preselected volume of gas has been inhaled and has a mechanism which can be preset to change said preselected volume to a second larger preselected volume automatically after a chosen number of respiratory cycles or a chosen time interval. The gases pass through a mixer 2 and devices 4, 6 which regulate the pattern and rate of flow to a valve 8. A sensor 12 sends a pulse to an integrator 14 every time a unit volume of gas passes the sensor. A volt meter 46 records the tidal volume and the signal from the integrator 14 is compared by a comparator 36 to a signal produced by either a generator 38 corresponding to the normal preselected inspiratory gas flow volume or a generator 50 corresponding to a greater inspiratory gas flow volume: When the signals balance the comparator causes a control unit 10 to close valves 8 and 34. A timer 40 is then started which resets the comparator after a selected expiratory time. During this time the gases exhaled by the patient pass along a tube 22 through a sensor 26 and out of a non-. return exhalation valve 28 which is kept closed during the inspiratory phase by pressure of gas in a tube 30. When the valve 34 is closed the pressure in the tube 30 is reduced and the exhalation valve 28 may be opened. When the comparator is reset the inspiratory mode is again operative. Everytime the comparator is reset a signal is sent to a unit 48 which, when. the predetermined number of respiratory pulses has been completed connect the generator 50 to the comparator 36 in place of the generator 38, causing the supply of a larger respiratory volume to the patient so that he takes one or more deep breaths before generator 38 is reincorporated into the circuit. The reading on a meter 42 indicates the minute volume and an alarm 44 sounds if the reading rises or falls excessively. A manual .rebreathing device 24 may be incorporated into a multi-port valve 16 which connects the patient to the ventilator.
