Filed: 1962-04-26
Abstract: 993,943. Laminates. LIBBEY-OWENSFORD GLASS CO. April 26, 1962 [May 4, 1961], No. 15867/62. Heading B5N. In a glass laminate in the form of a curved vehicle windscreen comprising two sheets of glass having an interposed sheet of polyvinyl butyral, one of the glass sheets is thicker than the other and the thinner sheet is nested in the thicker and constitutes the inner sheet in the vehicle. Preferably the thicker sheet 14, Fig. 3, exceeds in thickness that of the thinner sheet 15 and interlayer 16 combined. Typical thieknesses for the glass sheets are 0.130-0.170 inch and 0À040-0À110 inch, and for the interlayer 0À01-0À045 inch. The glass sheets may be of heat-absorbing glass, and the upper part of the interlayer may be coloured to reduce glare, the thicker glass then providing greater protection against fading. Tests are described demonstrating that laminates, according to the invention, have greater resistance to bending, and to impact from without and within a vehicle, and that less glass is dislodged from them when broken on impact.

Title: Improvements in incendiary shells
IPC: F42B12/44
Filed: 1920-06-12
Abstract: 144,736. Hammond, J. H. Dec. 21, 1914, [Convention date]. Projectiles.-Consists in making projectiles with an exothermic non-explosive charge T and an explosive charge E; a charge H of poisonous material such as hydrocyanic acid may be added. The exothermic charge, for example of the substance known commercially under the Trade Mark " Thermit," is set alight at the moment the shell is discharged from the gun, for example by one, or more, concussion fuses C which ignite a priming charge I of barium peroxide and aluminium. The ignition is transmitted from this charge to the exothermic charge directly or through a charge U of red oxide of iron and aluminium contained in a tube L and flat hollow disks J of paper or pasteboard. The explosive charge E, for example of trinitrotoluene, is detonated by a percussion fuse F after the projectile has penetrated the target and the exothermic reaction has had time to be completed. The explosion scatters the exothermic charge with incendiary effects and also the poisonous charge when one is used. Shrapnel bullets coated with refractory materials may be added to the exothermic charge, and the chamber containing this charge is lined and divided from the adjacent chamber by refractory heat-insulating material M.

Title: Improvements in or relating to free tripping overload electric switches
IPC: H01H71/50
Filed: 1950-06-27
Abstract: 679,232. Automatic circuit-breakers. IGRANIC ELECTRIC CO., Ltd. June 27, 1950. [June 27, 1949] No. 16034/50. Class 38 (v). A free-tripping, overload-responsive switch has a rectilinearly-movable element which when released moves the pivots of a contact-carrying switch member to open the contacts. The switch has a fixed contact 11 and a moving contact on the switch member 14 which is pivoted at 14a to the rectilinearly-movable element 15. The latter is biased downwardly by a spring 16 but is normally held in its uppermost position, Fig. 2, by a current-carrying bimetal strip 18, the free end of which engages a portion 15d of the element 15. The free end of the member 14 is connected by a snap-acting, over-centre spring 25 to an arm 23c on a toggle member 23 which is pivoted at 23b. The switch is closed by moving the operating lever 24 to the dottedline position, Fig. 2, the forked end 24a of the lever which engages a pin 28 on the member 23, turning the member 23 clockwise about its pivots 23b to move the arm 23c down to a position where the spring 25 snaps over-centre and causes the free end of the switch member 14 to move down to close the contacts. If an overload occurs, the bimetal strip distorts, releasing the element 15, which moves downwardly carrying with it the pivoted end of the member 14. The member 14 strikes against projections 10c on the walls of the switch housing 10, causing it to move into the tripped position, Fig. 3. The member 23 is now relieved of much of the tension of the spring 25, so that a light spring 29 is able to move the member 23 into the position of Fig. 3 where the lever 24 is in a central position indicating that the switch has tripped, and a projection 23d of the member 23 abuts the underside of an extension 15c of the element 15. To reset the switch, the lever 24 is restored to the "off" position shown in full lines in Fig. 2. This movement of the lever 24 turns the member 23 anticlockwise about its pivot 23b so that the projection 23d moves the element 15 up to the position where it is latched by the strip 18, the contacts remaining open during this operation. The projections 10c are so situated in relation to the pivots 14a in their lower position, that retention of the lever 24 in the "on" position does not prevent the tripping of the switch. The switch is opened manually by moving the lever 24 to its "off" position, so moving the spring 25 over-centre to open the contacts. The operating lever 24 may be provided with a dust boot 30. The bracket 18b supporting the bimetal strip 18 has an arm 18c engaged by a screw 21 for current-setting purposes.

Abstract: 530,001. Spraying plaster. SCHUETZ, H. June 1, 1939, No. 16155. [Class 20 (ii)] [Also in Group XXIX] A spray-gun for projecting a plaster mixture on to a surface is provided in the outlet tube 12, Fig. 2, with an axially-disposed rod 13 which causes the issuing plaster to be of annular crosssection, and this plaster is then finely. broken up by compressed air which flows through a further tube 19 arranged around the said outlet tube. The plaster is fed. to the tube 12 through a tube 10, and the compressed air passes from a tube 14 to the mouthpiece 15. The mouthpiece is screwed on the tube 19 and the flow of compressed air depends upon the position of this member on the gun. The outflow of plaster can be regulated by substituting one headed member 18 which is screwed on to the end of the rod 13 for another of smaller or greater diameter. The plaster mixture is contained, prior to spraying, in a. vessel 1, Fig. 1, in which it is mixed by means of compressed air fed to the lower part of the vessel through apertures 17 in a pipe 3. The plaster mixture may consist of asbestos fibre, pipe clay, cement, river sand or marble meal, and water; alternatively, the mixture may consist of white asbestos, marble meal, pipe clay, cement, colouring matter, and a waterproofing agent such as a fluosilicate or ceresin.

[Class 83 (iii)] [See also Group XXIII] A detector member 5a is in contact with the surface of the work 2 which is being turned, and when the desired diameter is obtained, causes the interruption of a beam of light or other radiant energy falling on a photo-electric or like cell, which through relays then actuates the stop-gear. In the construction shown, the detector or contact member 5a is mounted on a lever 5 pivoted by means of a flexible strip 12 to an arm 6a extending from a housing 6 which, as shown in Fig. 3, is divided into three chambers containing respectively a lamp 18, a pivoted shutter 14, and the sensitive cell 17. The light from the lamp normally passes to the cell through slots 6w, 6d in the partitions between the chambers, but as the work is reduced in size the lever 5, which engages a short arm 13 on the spindle of the shutter 14, moves and allows the shutter 14 to turn under the action of a spring 13 until it closes the slot 6d and causes the cell 17 to actuate the stop gear. The housing 6 is pivoted at 7a to a bracket 7 carried on a pillar 8, and is tilted against the tension of a spring 10 by a screw 11 to adjust the contact member 5a in relation to the work. A pointer 14x carried by the shutter moves over a scale to give an indication of the progress of the work. The photo-electric cell controls a series of amplifying valves A which cause the actuation of electromagnetic relays 22, 24 controlling the energization of a magnet 25 which actuates clutch mechanism or like transmitting members of the machine. In a modification, Fig. 5, the detector or contact member is mounted on the lower end of a vertically-slidable rod, and rests by gravity on the work.
