Title: Improvements in Filling Feeler Mechanism for Automatic Weft Replenishing Looms.
IPC: D03D51/34
Filed: 1917-03-30
Abstract: 111,784. British Northrop Loom Co., (Northrop Loom Co.). March 30, 1917. Weft-replenishing mechanism. - In self-contained weft-feeler mechanism, the feeler comprises a weft-feeling member 12, Fig. 5, with a broad end 14 adapted to enter the shuttle 4 at the beat-up and contact with the weft 15 on the bobbin, a normally retracted carrier 26 movable relatively to the member 12, a shuttle-impinging member 33 adjustably carried by levers 27, pivoted at 28 on the member 12, and connected by the levers to the carrier 26 to move reversely therewith, and a penetrating-member 38 yieldingly projected from and slidable in the carrier, the arrangement being such that when the member 33 is pressed forwards by the shuttle against the action of a spring 36, the carrier 26 and the member 38 are projected towards the weft-bobbin and a point 39 on the member 38 penetrates the weft and eventually makes contact with the bobbin so that the member 38 is moved forwards relatively to the carrier against the action of a spring 42, a pin-and-slot connexion 40, 41 permitting this movement. A flexible sheath 50 has one end secured to the end of the carrier 26, and contains a flexible core, such as a wire 55, connected by a pin 56 to the member 38. The other end of the sheath is secured to a bracket 53, Fig. 4, below the forward end of a dog 45 pivoted at 46 to an arm 44 on the initiating-shaft of the weft-replenishing mechanism, and the wire 55 ends in a pin 57, which is raised when the wire is moved in its sheath and moves the dog 45, against the action of a spring 48, to place its rearward end in the path of a weft-hammer 47 so that the initiating-shaft is rocked. The weft-feeling member 12 is secured to the upper end of a vertical lever 9, which is yieldingly pressed rearwards against a stop by a spring surrounding a rod pivoted at 19 to the upper end of the lever 9, the spring being confined by a fixed bracket through which the rod passes; the weft feeler is thus free to yield when pressed by the weft on the bobbin.

Title: Improvements in or relating to smoke observation apparatus
Inventor: STRANG JOHN MARTIN
IPC: F23N5/08
Filed: 1953-02-19
Abstract: 785,019. Observing smoke. BARR & STROUD, Ltd. Jan. 28, 1954 [Feb. 19, 1953; Dec. 21, 1953], Nos. 4636/53 and 35436/53. Class 51 (1). [Also in Group XX] A smoke observation apparatus comprises a light source directing a beam across a smoke conduit, and means for intercepting the beam after passage through the smoke to focus an image of the smoke on a light dispersive screen so that the image may be viewed over a wide angle. A lamp unit 7 projects a beam of light across the uptake 6 of an oil-fired boiler on to a mirror unit 9 which reflects the beam down an upright tube 10 to a mirror unit 11 which reflects the beam on to an upright viewing screen 12 of frosted glass or plastic material. The lamp unit 7 comprises a cylindrical part 14a perpendicular to the uptake 6 and welded into a hole in the uptake wall, a second part 14b connected to the part 14a by a bayonet connection and carrying a condenser lens 23 of heatresistant glass sealed to its inner end so as to close the uptake 6. A third part 14c bolted to the outer end of the part 14b carries a lamp socket. A one-way inlet 25 in the part 14a enables compressed air to be blown across the uptake side of the lens 23 to clean it. A part 26 is welded into the uptake 6 opposite the part 14a and the mirror unit 9 screws over its outer end. A window 42 of heat-resistant glass is hingedly mounted at the inner end of the mirror unit 9 and clamped against the outer end of the part 26 which has an inlet 45 to allow the window 42 to be cleaned by compressed air. A mirror 31 is carried by an adjustable three-point suspension on a cover plate 34 which is hinged and clamped to the mirror unit 9. The mirror 31 is at an angle of 45 degrees to the window 42 and a projector lens 13 clamped to the lower end of the unit 9. The vertical part 10 is screwed to the lower end of the unit 9 and the base mirror unit 11 is screwed to the lower end of the tube 10. A mirror 47 is mounted in the unit 11 in a similar manner and parallel to the mirror 31 mounted in the unit 9. A screen 12 is supported vertically in an extension of the unit 11. An auxiliary light source may be arranged to form a spot of light on the screen, and the illumination intensity of the light spot may be varied by a rheostat controlling the source or an adjustable filter between the source and the screen so that the density of the smoke may be estimated. Alternatively a ring of light filters of different densities may be provided on the screen so that by observing the lowest density filters which remains completely dark, the density of the smoke may be estimated. In a further modification a jet of compressed air injected into the part 26 causes turbulence in the smoke in the flue at the end of the part 26 and makes it more easily visible on the screen.

Title: Improvements in bending sheets of glass
IPC: C03B23/025
Filed: 1959-02-13
Abstract: A glass sheet is bent on a mould by exposing the whole sheet to radiant heat directed towards one face of the sheet while selectively regulating the heat absorbed by the glass by forming on one or more predetermined areas, such as those to be bent most severely, a temporary coating of discrete particles on the surface remote from the source of radiant heat, which particles totally reflect back through the glass the heat radiated to them so that the amount of heat absorbed by the glass in these areas is increased.  Preferably, the areas either side of an area so coated are similarly coated on the opposite face to diminish the heat absorbed by the glass on either side.  The effect of the coating may be modified near the periphery of the coating by giving a serrated edge to the coating or by diminishing the concentration of the particles in the marginal areas.  The coating may be a dusted on powder, but preferably is applied as a suspension in a liquid sprayed or brushed on to the glass.  White-wash, french-chalk, kieselguhr powdered talc or asbestos or red oxide of iron are suggested coatings.  Removal is by brushing or suction.
