Title: Combustion engine air and fuel charge forming devices
IPC: F02D19/06
Filed: 1974-11-07
Abstract: 1468080 Carburetter and vaporizer system E C AUTHEMENT G G VARVARO F S STUPKA O J WAGUESPACK S J TABOR and M R GUELL 7 Nov 1974 [23 July 1974] 48281/74 Headings F1B and F1H A combustion engine is provided with a carburetter 20 for starting purposes and with a vaporizer 52 for hot-running. Air from a supercharger 30 is pre-heated in a heat exchanger 38 and passes along a conduit 40, 46 to entrain fuel from a float chamber carburetter 20 and thence to an induction manifold 22. Fuel is pumped from a line 58 through an electric pre-heater 68, through a 3-way valve 72 to the carburetter 20. As the engine warms up two thermostats 104, 106 are triggered, the first 104 opening a valve 100 which allows air to flow along a pipe 48 into a vaporizing chamber 52 and via pipes 94, 96, to the conduit 46 and the induction manifold 22. The second thermostat 106, switches off the electric fuel pre-heater 68 and adjusts the 3-way valve 72 so that no fuel flows through a conduit 76 to the carburetter 20 and so that the fuel is redirected along conduit 80 where it is pre-heated by engine coolant in chamber 86 before leaving a nozzle 88. Below the nozzle 88 a jet of air 56 impinges upon the fuel to prepare a fuel-air mixture. Instead of engine coolant, pre-heated air may flow into the chamber 86.

Abstract: 1279970 Film fibrillation SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 13 Oct 1969 [15 Oct 1968] 48868/68 Heading B5B Fibrous products are obtained by passing a longitudinally oriented thermoplastics film, e.g. of polyethylene or polypropylene, under tension and in an arcuate path over the periphery of a roll whose surface is covered with a plurality of rows of pins 199, the rows being parallel to the roll axis and the tips of the pins being rearwardly inclined, the roll having a peripheral speed faster than and in the same direction as the film travels, whereby the film is subjected "simultaneously" to the action of a sufficient plurality of rows of pins to become stretch breakable, and thereafter effecting stretchbreaking, e.g. by means of nip rolls. By "simultaneously" is meant the condition in which any portion of film is impacted by the pins of a plurality of rows while the said portion lies in the arcuate path referred to above. Nip-rollers may be used to control tension; a lay-on roll movable about the axis of the pinned roll may control the magnitude of the arc of contact of the film with the pinned roll; adjustable bars may control the removal -of the film from the roll. Fibrillators.-In Fig. 4 pins 199 are carried on bars 104 rotatable about their axes and held by screws in end-plate 96. Each bar carries a cranked arm 110, the cranked end of which engages slot 108 in a plate (106, Fig. 5, not shown). This plate is rotatable about the rod axes by means of screwed rod 116 rotatably fixed at 118 and screwed diametrically through spigot 112 on the plate. Rotation of the plate causes simultaneous adjustment of the inclination of all the pin-rods 104.

Title: Method for making thermographic copies
IPC: G03C1/705
Filed: 1962-12-28
Abstract: 1,034,798. Photographic and thermographic materials. MINNESOTA MINING & MANUFACTURING CO. Dec.28,1962,No.46878/62. Heading G2C. A master sheet for making thermographic copies from a light image is obtained by imagewise exposing to light a copysheet comprising a layer having indium oxide powder uniformly distributed therein so that the indium oxide in the exposed areas becomes more infra-red absorptive. Alternatively, the indium oxide layer may be uniformly exposed to light to increase the infra-red absorptivity and then image-wise exposed to heat lowering the increase absorptivity in the exposed areas to leave a master sheet. The indium oxide may be dispersed in a binder which is coated on a support or may be directly distributed within a relatively porous support e.g. paper or fabric and its sensibility extended to longer wavelengths than green by addition of dye sensitives. The copysheet should have sufficiently low lateral thermal conductivity to permit its use in thermographic processes, any coatings between the indium oxide and the light source should be transparent, and the lacking should be infra-red transmissive. Heat-sensitive reactents may additionally be incorporated in the same or a separate layer as also may a material such as gallic acid or quinalizarin green which is vapourizable after imagewise exposure to light and then uniform exposure to infra-red and can condense to give an image on an adjacent receptor surface. The infra-red absorptive image may be erased by heating above 100C and the copysheet re-used. Examples illustrate the use of a copysheet image-wise exposed to light as a master for conventional thermographic copying; a copy sheet uniformly exposed to light and then to heat in contact with a typewritten page being used as a master to obtain a reverse image; and the use of a copy sheet containing appropriate heat-sensitive reactants to give a more pronounced image. Alternatively the light exposed indium oxide may be coated with a heat sensitive dye complex which is destroyed in the exposed areas to give a negative image.

Abstract: 1,158,899. Photo-electric fault detection. BELOIT CORP. Nov. 15, 1966 [Jan. 5, 1966], No.51089/66. Heading G1A. Defects in a travelling web of paper 11 are detected photo-electrically before sections of the web having defects reach coating apparatus 12, 13, so that the latter may be deactivated to allow the faulty sections to pass through uncoated and thereby prevent fouling of the coating apparatus and breaking of the web. In one arrangement, Fig. 1 holes and relatively thin parts of the web are detected by photo-electric inspection apparatus 16, 17 which may comprise a single light source-detector combination or an array of these. If the intensity transmitted by the web is above the level set in automatically- or manually-adjustable means 20, indicating the presence of a fault, relay 18 is actuated to activate sequencing device 21. This causes: marking of the defective web section (via control 23); disengagement of coating rollers from the web or lowering of the pans of coating fluid in coaters 12, 13 (via control 24); and disengagement of the coater wiper blades (via control 25). Also a timer or footage control 26 is started. The defective portion of web is allowed to pass through the coaters uncoated, and after a predetermined time set into control 26, a second sequencing device 29 is activated and the timer 26 stopped and reset. The device 29 controls reactivation of the coating apparatus by reengagement of rollers, wipers &c., and resetting of relay 18. In a modification, Fig. 2 (not shown), defects are detected as instantaneous variations of mass per unit area from an average value of transmitted light. Variations above a pre-set value control deactivation of the coaters for a pre-set time which can be adjusted. Parts of this control system are described in more detail i.e. the device which compares the variation level with a predetermined value, Fig. 3 (not shown); the deactivation sequencing device, Fig. 4 (not shown); and the device for producing a signal representative of the instantaneous variation from the average value, Fig. 5 (not shown).

Filed: 1967-11-10
Abstract: 1,209,758. Packaging. PNEUMATIC SCALE CORP. 10 Nov., 1967, No. 51333/67. Heading B8C. A packaging machine includes an adhesive applying mechanism which includes rotary adhesive applying elements 22, means for advancing a carton blank 10 into operative relation to the applying mechanism, normally inoperative means associated with the rotary elements for moving the carton blank 10 out of operative relation to the rotary elements, and means responsive to the stopping of the machine for actuating the normally inoperative means to move the carton blank out of operative relation to the applying mechanism whereby to prevent adherence of the blank to the same during prolonged stoppage of the machine. As shown, in which the carton blanks are fed by a chain conveyer 14 to the elements 22 the latter are supplied with liquid adhesive fed from a tank 35 to rolls 26, 28. A cam-operated backing roll 32 co-operates with the elements 22 into pressing engagement with the underside of the carton blank during adhesive applying operation by a spring 40. In operation, the roll 32 is held out of engagement by a cam 48 until a carton blank 10 reaches the adhesive applying position. When the machine comes to rest, the roll 32 is rocked away from the carton blank pneumatically, independently of cam 48, by means of an arm 50 which co-operates with a plunger 52 of an air cylinder 54. The blank is also pressed away from the elements 22 when the machine is stopped by means of fingers 62 carried on a pivotable shaft 64 and extending out of the path of the elements 22 above a blank 10. The fingers are connected together to move as a unit by rods 76 and 80. The fingers are normally held off the blank 10 by a spring pressed plunger 86 and are movable into contact with the blank 10 by a plunger of an air cylinder 95. The free ends 100 of the fingers 62 extend beyond the elements 22 and are effective to reject a faulty blank whereby to rock the fingers 22 upwardly and open a micro-switch 102 in a control circuit which stops the machine. The control circuit, Fig. 5 (not shown), includes a machine driving motor starter solenoid (112) controlled by a start button (114) and holding contacts (118). A solenoid air valve (120), which is normally open, is energized by a relay (126) to close contacts (128) when the motor is started. If a stop button (130) is depressed or the micro-switch 102 is operated, relay (126) is de-energized to open contacts (128) and the valve (120) to allow operation of cylinders 54 and 95 and consequently movement of roll 32 and fingers 62. A three position switch (136) provides a "RUN" position, a "SAFE" or "OFF" position and a "JOGGING" position, for operation of the machine. United States Specification 3,322,043 is referred to.
