Title: Stove burning fuel from a can
Inventor: BETTINARDI LUIGI GIACOMO
IPC: F24C1/16
Filed: 1987-09-28
Abstract: The invention concerns a stove consisting of a container (1) containing fuel of a gelatinous type and of a spacing support (2) having vertical diverging walls provided with a series of holes. 
     The container is a can and it also acts as a combustion chamber. 
     On the lower par of the spacing support (2) some hooks (6) are obtained which fit into a circumferential groove (4) being present on the edge (3) of tank 1. 
     The inside diameter of the spacing support (2) is wider than the external diameter of the container (1) and this permits to axially fit said support over the container with an obvious reduction of the overall dimensions.

Abstract: A multi-component chucking system, in particular for concentric or true-rotation tools, has a recieving body (1) optionally having a chucking shaft, with an engagement surface (8) extending at right angles to the axis of rotation (2) and a coaxial retention bore (7) as well as a tool element (9), preferably embodied as a tool holder. On its end face, the tool element also has an engagement surface (11) at right angles to the axis of rotation and is formed with a coaxial retention stub (10) fitting into the retention bore (7), by means of which stub the tool element can be centered with respect to the receiving body. A chucking pin (18) associated with the retention stub and coaxial with the axis of rotation, along with chucking means actuatable from outside the receiving body, allows the clamping together of the tool element and the receiving body. The chucking means have two radially movably supported locking elements (27), which have locking surfaces by which, in a chucking position, wedge-like surface regions (21) of the chucking pin (18 ) that are inclined with respect to the axis of rotation are engaged from below. These wedge-like surface regions of the chucking pin are located on a single common conical surface region that is coaxial with the axis of rotation and forms an acute angle (22) with it.

Inventor: THROCKMORTON MORFORD CHURCH
IPC: C08F4/60
Filed: 1987-04-07
Abstract: Lanthanide and actinide catalyst systems normally appear to be "pseudo-living" when they are used to polymerize conjugated diolefin monomers into polymers. Polymerizations which are catalyzed with such catalyst systems produce polymers which have increasingly high molecular weight as monomer conversions are increased. Consequently, any change in polymerization time or conversion may affect the polymer's ultimate molecular weight. This has made controlling the molecular weight of polymers which are made utilizing lanthanide and actinide catalysts difficult. 
     It has been unexpectedly discovered that vinyl halides can be used as molecular weight regulators for polymerizations which are catalyzed with lanthanide and actinide catalyst systems. Accordingly, the present invention relates to a process which comprises polymerizing at least one conjugated diolefin monomer in the presence of (a) a catalyst system which is comprised of (1) an organoaluminum compound, (2) an organometallic compound which contains a metal from Group III-B of the Periodic System, and (3) at least one compound which contains at least one labile halide ion; and (b) a vinyl halide.

Title: Valve supervisory switch
Inventor: MERCHANT DAVID E
IPC: H01H3/16
Filed: 1987-09-14
Abstract: A switch is mounted on a plate within a housing having a housing body with a port and a removable housing cover. A switch actuator rod is mounted on a pivot within a sleeve that may be coupled to the housing so that the rod extends through the port and engages the switch within the housing. A linear actuator rod is slideably mounted within a sleeve which also may be coupled to the housing so that the rod extends through the port and engages the switch. A spring is mounted on the housing cover in a direction traverse to the arc through which the swing actuator rod pivots so that it engages the end of rod and biases it away from the switch. By removing the cover, moving the rod to the opposite end of its arc, and replacing the cover, the direction of engagement of the rod with the spring may be changed. The switch plate is movable along the rod's arc of pivot so that the           tch trip point along the arc may be adjusted.
Patent EP-0233119-A2 (EP)
Inventor: FARGE HERVE MARIE JACQUES
IPC: C08F292/00
Filed: 1987-02-05
Abstract: The invention relates to the use of chemical grafting to produce a stable liquid composition that is capable of hardening following an optional polymerization process. Under the invention, in order to produce a composition that is liquid, at least initially and prior to any polymerization, a polymerizable organic acid comprising at least two double bonds in resonance is combined in a solvent with an inorganic filler having at least one hydroxylated group with the help of a catalyst acting as a radical upon said organic acid. By adjusting the concentration of catalyst and using a polymerizable monomer solvent, the liquid composition may be hardened by polymerization after the initial grafting reaction. By ensuring that a portion of the organic acid retains free bonds that have not combined with filler, it is also possible to induce the composition to become chemically attached to a resin or to reinforcing fibers. The invention may be applied to the production of molded objects.

Title: Paper punch

Abstract: In paper punches made of relatively weak sheet steel, there is a risk, when perforating cardboard or relatively large piles of paper, of the punch guides bending up and hence of premature wear. This risk is countered in paper punches in which the punch guides (7) are integrally formed on the side pieces (1) by the fact that the punch guides (30,31,32,33), produced together with the side piece (1) from a one-piece blank, are connected by additional stiffening connections (3,24; 34) to the holding part (2) and the side piece (1) of the bearing block, so as to be flexurally rigid. <IMAGE>

Inventor: LACH HORST
IPC: B24B49/10
Filed: 1988-05-19
Abstract: The method provides for an electric spark voltage to first of all be applied between grinding tool (18) and workpiece when the grinding tool (18) touches the workpiece (10) and for the touching position to be determined by the spark current. The spark voltage is then switched off for the grinding operation or set to such a value that essentially only mechanical removal of material takes place. The method can be carried out especially advantageously on an apparatus which is designed for spark erosion processes or erosion grinding, because the control circuit (32) available for this can be used not only for the control of the spark gap during the erosion machining but also for touching of the grinding tool.

Abstract: Die Erfindung betrifft eine Einrichtung (20) für eine unipolar betriebene energiespeicherfähige Komponente (9). Diese Einrichtung (20) kann beispielsweise bei einer asymmetrischen Halbbrückenschaltung (1) Anwendung finden.

Abstract: An illuminated display unit such as a house number, traffic sign, advertisement carrier and the like comprises a fluorescing or photoconductive plate adjacent an edge of which is fitted at least one light-emitting element, in particular a light-emitting diode. The edge is provided with a reflecting layer to prevent emergence of light. Display symbols or their negatives are arranged, as viewed by the onlooker, on the rear face of the photoconductive plate. As a result of the total reflection for a photoconductive plate on the front and back and on the reflecting layer at the edges, the light produced by the light-emitting diode can issue only at the contact surface with the display symbols, so that the light is concentrated very strongly there and a great display brightness is produced. This is even more effective when a contrast surface is arranged behind the plate. In this way great display brightness can be produced with very low electric power, permitting continuous operation or operation with a small number of solar cells.
