Title: Computer-generated autostereography method and apparatus
Inventor: MEYERS STEPHAN B
IPC: G06T15/00
Filed: 1995-06-13
Abstract: A method and apparatus for making autostereographic images (115, 116) wherein a computer (105) is provided with a number of planar images in a digital form (101, 102), in a two-dimensional array of columns and rows of digital data. The columns are interleaved and rotated to form an interleaved and rotated image so that the interleaved columns of the rotated image are substantially unaligned with the rows and columns of the digital representation of this image. The digital representation of the image is rotated using an algorithm that is independent of resolution and number of input images. The resulting image is then output on a high resolution imaging device (106, 107) so that the columns of interleaving are substantially unaligned with both the direction of printing and the normal to direction of printing. The output from the high resolution imaging device (106, 107) is then placed in a registered relationship with a means for viewing (113, 114) selected ones of the input images, such as a lenticular or barrier screen.

Abstract: A twin tube air brake hose for delivering compressed air to brakes on a vehicle such as a truck includes a first tube which serves as a service tube and a second tube which serves as an emergency tube. The first tube and second tube have an inner layer surrounded by a reinforcing layer which is in turn surrounded by an outer rubber layer. The outer rubber layers of each tube are joined by a web which is unitary with the outer layers. Adjacent opposite ends of the twin tube brake hose, the tubes are separated to form free end portions, each of which have a metal fitting. Reinforcing bands are fitted around the twin tube air brake hose just inboard the tail ends to prevent the web from splitting.

Title: Steel production method
Inventor: BONOMETTI NATALE
IPC: C21C5/52
Filed: 1998-08-07
Abstract: The invention relates to a method to produce steel from a ferrous material, by using one furnace divided into, at least, two vessels which are connected to each other at least by ducts for the off-gases and ducts for the melted metal. The vessels have a growing capacity starting from the first one; the material to be cast is divided into a first charge for the first vessel and a second charge for, at lesast, a second vessel of the furnace, the charge of the material in the first vessel of the furnace is melted using electric energy and/or combustion energy; the off-gases from the first vessel of the furnace are sent to the second vessel of the furnace in order to heat the charge of material in said second vessel, and the off-gases in the second vessel are sent to the first vessel to heat the material in this first vessel; the metal melted in the first vessel is poured in the second vessel of the furnace in order to contribute with its own thermal energy and with combustion energy to the melting of the material charged in the, at least, second vessel; the metal melted in the second vessel is poured for the use.
Patent CA-2248433-A1 (CA)
Title: Inductive braking in a dual coil speaker driver unit
Inventor: BUTTON DOUGLAS J
IPC: H04R9/02
Filed: 1998-09-22
Abstract: An electro-magnetic loudspeaker, with dual voice coils operating in corresponding magnetic fields in annular gaps between permanent magnet pole pieces, is provided with a single short-circuited braking coil of one or more turns mounted on the voice coil form midway between the two voice coils. The braking coil has minimal effect on normal operation of the loudspeaker, but introduces an inductive braking effect from counter-EMF whenever the voice coil assembly displacement approaches a working limit in either direction, as the braking coil enters a corresponding one of the two magnetized gaps. Thus bidirectional braking/damping is accomplished in a dual coil speaker by the addition of a single braking coil, which could be simply a one turn ring; whereas bidirectional inductive braking in a speaker with a single voice coil requires two such braking coils flanking the voice coil. The single braking/damping coil can be brought out to terminals for connecting it in a loop circuit with an active feedback driver and/or a network of one or more reactive components, for modifying and enhancing the braking/damping action.
