Title: Occlusion processing via divisible bounding or bounded volumes
Inventor: NYSTAD JOERN
IPC: G06T15/40
Filed: 2009-06-04
Abstract: A method of processing a scene for display, in a graphics system, comprises identifying a scene object 50, generating a volume representing the object 51, processing 52 some or all of the scene using the volume for the object to assess the presence of an object, and determining 53 whether or not to process the object as a result. Briefly, before detailed rendering of, for example, primitives and vertices of an object, the method assesses whether the object will be visible, occluded or hidden (fully or partially) in the final scene; then, it only carries out rendering/rasterising on visible objects or parts thereof, reducing rendering processing load and increasing rendering speed. The occlusion testing or culling volume may be a bounding volume or box (4, bounding car object 3, Figure 2) surrounding the object; an initial, single bounding volume may be divided or split (Figures 7-10) to improve processing of partially visible objects. A bounded volume (70, Figure 11) may be used for assessing other scene objects. A z-only rendering pass may be performed, and the method may be applied to a vertex shader system (Figure 12).

Title: Improvements in carburetters for internal combustion engines
IPC: F02M21/00
Filed: 1921-04-09
Abstract: 181,544. Saunders, A. April 9, 1921. Spray carburettors.-A float-less carburettor has a suction-actuated valve which cuts off the supply of fuel to the main and pilot jets when the engine is not working. Initial adjustment means operable from outside the carburettor, are provided in the main fuel supply and in the passage to the pilot jet, and the main jet is varied simultaneously with the air supply. Fig. 1 shows a section through the main jet and suction-actuated valve of the carburettor. Fuel is supplied through a passage A controlled by a cock 2 to the seating of a valve C which is normally kept closed by a spring J. When the engine starts, the suction acts on a cup G on the valve stem and brings a surface D on the valve into contact with a seating in a plug K to prevent escape of fuel around the valve stem, and at the same time permits fuel to flow through passages P and I, Fig. 2. The passage I is adjusted bv a cock B, operated from outside the carburettor, and constitutes the pilot jet, an air passage M intersecting the passage I at right-angles. The passage P leads to a main valve R which is closed during slow running by a spring. The valve R is raised by a finger C<1> on a plunger U which is engaged by an adjustably inclined surface on the main air valve S, as described in Specification 120,839. The flow of fuel is controlled bv tapered grooves W in the valve stem A<1> which passes through a plug B<2> having air passages for breaking up the jets. The plunger U has a tapered upper portion which is pressed on to a conical seating by a spring during slow running.

April 9, 1936, No. 10519. Convention date, May 25, 1935. [Class 100 (ii)] Apparatus for printing designs on fabrics by means of perforated'surfaces such as stencils or perforated metal plates to which colour is applied, comprises a stencil-supporting carriage movable along a table 1, and spring detents engaging the carriage for stopping it in the required positions, the carriage including a frame in which is stretched the stencil and which is capable of being raised from the frame by first pivoting it about one of its edges resting on the fabric and subsequently by pivoting it about an axis above the fabric. The carriage 4 is provided with rollers 5, 6 running on rails 2, 3, a rim 7 on the roller 6 and a horizontal roller 8 adjustable on an eccentric mounting co-operating with the rail 3 to guide the carriage. On a bar 16 forming part of the carriage is mounted a slide 17 adjustable by a screwed spindle 18 and carrying a leaf-spring 20 with a stud 21 adapted to engage recesses in adjustable blocks 15 so as to set the carriage 4 to the required printing position relatively to the table 1. The stencil frame 25 is provided with pairs of lugs 36, 26 which engage respectively a bar 37 fixed to the carriage, and pins 27 on a.bar adjustable transversely of the carriage by a screw-and-nut device mounted on another bar 33. Adjustable collars 38 on the bar 37 secure the frame 25 in the required longitudinal position. The bar 33 is carried by blocks 43 slidable in curved guides 44 and adapted to be operated by a hand-lever 40. Normally, the frame 25 rests on the table 1 unsupported by the bars 33, 37. When the lever 40 is operated, the bar 33 is moved upwardly. During such movement, the lugs 26 are first engaged so as to tilt the frame 25 about the edge A. This movement causes the lugs 36 to come into contact with the bar 37 so that thereafter the frame tilts about the bar 37 and is lifted completely from the table. The carriage can now be moved to its next position as determined by the blocks 15 for printing another section of the fabric. In order to prevent movement of the fabric while the frame is being lifted, a series of spring-pressed pins 49 engaging the fabric are mounted on rods 46 pivoted to a bar 48 on the carriage. When the frame has been lifted clear of the fabric, the bar 33 engages the rods 46 and lifts the pins 49 clear of the fabric. Inking-apparatus.-A colour reservoir 53 is also mounted on the bar 48 and is provided at its base with perforations 55 adapted to be opened and closed by a slide 56 operated by a hand - lever 63 through a link - mechanism 58 ... 62.
