Abstract: 1,196,801. Resin-impregnated paper laminates. FORMICA INTERNATTONAL Ltd. (Formica Plastics Pty. Ltd.). 21 Feb., 1968 [21 Feb., 1967], No. 8116/67. Heading B5N. Decorative laminates for vertical cladding comprise a core and a decorative surface, each consisting of at least one thermosetting resinimpregnated paper sheet, with a coextensive thermoplastic resin barrier film bonded therebetween. The barrier film may be polyethylene, polyvinyl chloride or polyethylene ionomer and may be preformed, or extrusion coated on to a paper component. The assembled layers are bonded by heat and pressure, which serves also to cure the impregnating resins. The decorative surface may comprise a pigment-loaded paper impregnated with formaldehyde condensate, unsaturated polyester or modified alkyd resin, and should contain less than 44 wt. per cent resin impregnant; it may be provided with an a-cellulose paper overlay containing 60-70 wt. per cent resin. If such an overlay is used, the other surface sheets need contain no resin at the time of assembly, since migration occurs from the overlay. The core may comprise one or more sheets of kraft paper impregnated with phenol-formaldehyde resole, and the component sheets may be interleaved with thermoplastic resin barrier films. The laminate may be adhesively affixed to a base of hardboard, chipboard, plywood, blockboard or wood.

Title: Improvements in and relating to apparatus for light control in photographic apparatus
IPC: G03B7/04
Filed: 1935-03-18
Abstract: 453,845. Photographic exposure] meters. RISZDORFER, O., 1, Gellerthegy-utca, Ungarn, Budapest. March 18, 1935, No. 8345. Convention date, March 16, 1934. [Class 98 (i)] In photographic apparatus, the light falling on a light-sensitive device passes through slots or apertures in two or more screens, each of which is movable with respect to the other or others in accordance with an independent variable. As shown, a photo-electric cell 12 is placed behind two overlapping screens 13, 14. Radial slots 15 each of different width are provided in the screen 13 and the screen 14 contains three peripheral slots 16 of tapering shape. The screens are moved under the action of factors influencing the exposure such as shutter speed and diaphragm aperture, and control the size of the opening in front of the cell 12. Other factors such as the sensitivity of the emulsion may be taken into account by using light filters. The peripheral slots may be of constant width. In a modification two wedge-shaped slots are arranged at an angle to each other in two screens which are movable in accordance with the exposure variables. The Specification as open to inspection under Sect. 91 comprises also the use of grey wedges instead of slotted screens. Other photo-electric apparatus is described and includes an objective lens in which the photocell surrounds the lens in annular form, a screen of resilient material, e.g. rubber, textile fabric, preventing the effect of light arriving from a lateral direction. In apparatus shown in Fig. 22 (Cancelled), the photo cell 143, the objective lens tube 145, and the finder 146 are mounted on a common base plate 147, which is affixed to the casing 148 of photographic apparatus by a bayonet lock. Two coils 149, 150 fed by the photo electric current are mounted between the poles of magnets 151, 152, and carry at the end of levers 153, 154, two screening members 155, 156 which form a rectangular aperture 157 in front of the objective lens. In front of the cell 143 is mounted a diaphragm 160 coupled to one of the exposure variables. The aperture 157 is varied in accordance with the illumination, by movement of the screens 155, 156 in a vertical direction. The axis of the coils may be vertical and furnish a horizontal movement for the screens. In a modification three coils operate three screens to give an adjustable hexagonal aperture. In apparatus shown in Fig. 25 (Cancelled), the pointer 177 of the instrument 176 measuring the photo electric current is viewed by a double mirror arrangement 179, 181 through the usual finder arrangement 182, 183.

Class 110 (2) A rotary hydraulic engine or pump, of the intermittent abutment type, has vanes which move through an annular working chamber and are provided with means for connecting the vanes alternately to the rotor and the stator, the connecting or disengaging of a vane taking place when it is relieved of side pressure from the working chamber. In one construction, Figs. 1, 2, vanes 6, 7, 12, 13 supported by rings 51 on a stator 2, are coupled or un-coupled to a rotor 9 by means of rotary pins 8, 16, 17 in the stator through pinions 54 engaging toothed segments 58, 59, 60 on the inner periphery of the rotor. As a hydraulic engine, liquid enters the working spaces through a pipe 2, spaces 10 and a port 11, and leaves through a port 14 and spaces 15. The rotor 9 may be part of a wheel of a vehicle. Segmental ports 52, 53, Figs. 3, 4 (not shown) in the rotor and stator walls are used to relieve unilateral pressure on vanes 12, 13 in their positions shown in Fig. 2. Vane is discharging liquid through the port 14 as it is keyed to the rotor by the pin 8. The vanes 12, 13 are, at this time, being disengaged from the stator 4 and being brought into connection with the rotor 9. More than four vanes may be used. In a second arrangement, Figs. 7, 8 a stator 21 carries the inlet and outlet pipes and ports as shown by, the arrows, and the vane movements are controlled by lateral pins which engage grooves in the stator and rotor walls. Pins, on the vanes 29 . . . 34, are also engaged in slots in rollers 43 which are actuated by pins 48 in the rotor which co-act with slots 47 in the roller.s. Toothed wheels may be used instead of the pin-and-slot mechanism. Clearances at the ends of the vanes allow liquid flow therethrough while a vane is changing from stator to rotor, or vice-versa. Pressureequalization slots 27, 25 and 28, 24 are provided as shown.

Title: Internal combustion engine having spark timing control systems
IPC: F02P5/10
Filed: 1973-02-22
Abstract: 1387377 Timing ignition FORD MOTOR CO Ltd 22 Feb 1973 [24 Feb 1972] 8608/73 Heading F1B An internal-combustion engine has a carburetter induction passage 18 with a spark port 28 above the idle speed position of the throttle valve 26, a distributer breaker plate 12 spring- biased in a spark timing retarded direction, vacuum servo means 14 normally moving the breaker plate in an advanced timing direction as a function of increases in spark port vacuum applied thereto, conduit means 16 connecting the spark port to the servo means and control means momentarily advancing the timing to an advanced spark setting above that called for by the level of vacuum at the spark port in response to accelerative opening movement of the throttle valve and subsequently returning the timing to the spark timing setting called for by the spark port pressure level. Referring to the figure the force of the spring 82 is chosen such that when the throttle valve is opened to a position indicating acceleration operation the decrease in manifold vacuum in the port 30, reflected in the chambers 78 and 84, permits the spring 82 to stroke the diaphram 64 and thus the diaphram 66 to the left. This will increase the volume of the chamber 86 and lower the pressure in the line 88 and the chamber 46 of the servo 14. The flow restriction or orifice 52 in the line 16 prevents immediate communication of the vacuum in the spark port 28 to the servo chamber 46. Accordingly the vacuum induced in the chamber 86 will immediately cause a movement of the servo diaphram to the left to advance the ignition timing.
