Title: Bread baking oven
Inventor: PIERO LAGHETTI
Filed: 1982-01-12
Granted: 1989-11-30
Abstract: The apparatus has an X-ray source (3) having an electron source (31) and a stationary anode (4) which describes a full or partial anode ring with a circuit for accelerating electrons emitted from the electron source, using a high positive constant voltage, towards the anode ring. The electrons form an electron beam (32) which collides with the anode ring at a focal spot (41) which, in turn, emits X-ray radiation in the form of a fan beam (42). With a full or partial X-ray detector ring (5) the detector ring and the anode ring are coaxially arranged and define a scan slice. The detector ring is such as to permit the spatial resolution around the ring of the X-rays detected. A number of electron sources are arranged on an electron source ring (33) in proximity to the anode ring. A circuit is provided to control the sources individually in order to emit electron beams in set time sequence. The focal spots produced by the electron beams on the anode ring are each electromagnetically swept over a portion of the anode ring.

Title: Method for restoration of friability of material in a closed container
Inventor: DOROSEVAS VIKTORAS
IPC: B65G69/20
Filed: 2003-12-11
Abstract: The invention relates to methods for restoration of material friability and milling of material. Local and impulsive forces subject the cohered material being in a closed container. Predetermined charges are spread out into the volume of material according to a mathematic module, a surface of configuration and a delay mode of an explosion time, which is chosen by evaluating physical and mechanical properties of the material. A novel feature of the invention lies in the fact that the mathematic module allows to evaluate not only resilience of the material hardened in the closed container but also plastic deformation of the material.

Inventor: GUIDA ALLAN ABRAHAM
IPC: H04N7/26
Filed: 1989-08-30
Abstract: A video signal generating system develops an encoded video signal representing less than all of the video information. Auxiliary signal generating circuitry develops a pair of auxiliary signals representing in part the remaining video information. A first of the pair of auxiliary signals includes relatively high fidelity signal but with limited bandwidth. The second auxiliary signal includes relatively low fidelity information but has an effective higher bandwidth. Depending upon the information density of the auxiliary information, the first and second auxiliary signals are selected to produce an auxiliary output signal which is combined with the encoded video signal for transmission. A receiver responsive to the transmitted signal separates the video and auxiliary signals. The video and auxiliary signals are decoded and used to generate enhanced display images.

Abstract: 1,057,361. Power plant. F.J. WALLACE. Oct. 8, 1963 [Oct. 18, 1962], No. 15154/62. Heading F1Q. A propulsion unit comprises a piston engine, a main turbine to receive gas discharged from the engine, at least one compressor for supplying air to the engine, and an output member all drivingly connected together through means at least including differential gearing and at least one auxiliary turbine drivingly connected with the output member and so associated with the compressor as to receive part of the air delivered thereby at least at stall conditions of the output member. In Fig. 4 reference 1 designates a horizontally opposed two stroke compression ignition engine. The engine can be designed to use the uniflow scavenge system. A speed step up gear pair 20, 21 is used to connect the engine shaft 23 with a sun and planet differential gear 3. The gear wheel 21 is fixedly joined to the annulus 3a of the differential gear and the planet carrier 3b is drivingly connected to the output 5 through a sleeve 24 and a speed step down gear pair 25 and 26. Sun wheel 3c is arranged to drive a centrifugal compressor through a shaft 27. A shaft 28 and a gear wheel 29 connect the main turbine 2 with a gear wheel 30 secured to the sleeve 24 and a shaft 31 and speed step down gear pair 32, 33 connect the auxiliary turbine 7 with the sleeve 24. The speed of the sun wheel 3c may not be sufficiently high in certain circumstances to meet the speed requirements of the centrifugal compressor and it may then be necessary to resort to a further speed step up gear train between the sun wheel 3c and the compressor 4. In an alternative embodiment shown in Fig. 5 the engine shaft 23 is directly coupled to the annulus 3a of the differential gear, the planet gear carrier being drivingly connected to the output shaft through sleeve 24 and gears 25 and 26 and the sun wheel 3c being drivingly connected to a positive displacement compressor 37.

Date Apr. 30, 1981.A method for producing decorative glass objects in which the decoration is created by blisters formed by air bubbles within solid glass and/or by a pattern on the outer surface of the glass. When producing glass objects provided with air bubbles by means of known methods the bubbles remain on the surface of the objects which then easily break. In addition, the bubbles are formed at random, which may make them appear as dim impurities. When, in accordance with the invention, molten glass is poured from above in the shape of a band into a hot mould, the molten glass is spread into the mould in layers between which microscopic air bubbles remain. As the glass surface cools, the air enclosed within the bubbles expands in the molten glass which, while cooling, leaves the bubbles as clear pearls inside the glass. As the molten glass is spread in layers towards the wall of the mould, a pattern is formed as the glass surface cools.
