Abstract: An NTSC compatible, single broadcast channel, widescreen EDTV system encodes and decodes a television signal comprising four components: (1) a main, standard format NTSC signal (N) with low frequency side panel image information compressed into the overscan regions thereof; (2) time expanded high frequency side panel image information (X); (3) extended high frequency horizontal luminance image information (Z); and (4) vertical-temporal luminance image information (YTN). Components (2) (X) and (3) (Z) are intraframe averaged (64, 76) and quadrature modulate (80) an alternate subcarrier (ASC), e.g., at 3.108 MHz, to produce a modulated signal (M). The modulated signal is summed (40) with component (1) after intraframe averaging to produce an NTSC compatible 4.2 MHz baseband signal (NTSCF). This signal and component (4) quadrature modulate (57) an RF picture carrier to produce an NTSC compatible RF broadcast signal for transmission via a single broadcast channel.

Abstract: 673,190. Toothed gearing. HANSEN, D. Jan. 24, 1950 [Oct. 31, 1949], No. 1839/50. Class 80 (i). The casing 1 of a reduction gear unit is formed with' a removable side plate 8 having a, series of bores 9, 10, 11, 12 forming pairs with an identical series of bores in the opposite side of the casing. The pairs of bores are adapted to receive the bearings of shafts as required for selected pairs of gears to provide a desired reduction ratio and,disposition of input and output shafts, the bores not used being blanked off. A further opening 15 may be provided in the casing to receive a cover with a bearing adapted to enable a right-angled drive to be obtained with the use of bevel gears. Thus a single casing is adaptable to provide a series of reduction gear units with different ratios and different shaft dispositions. Three surfaces 2, 3 and 4 are machined to allow of securing the unit in three different planes. To provide for different powers a series of sizes of the casing may, be utilised but to enable standard sets of gears to be used in several sizes of the units all but one of the centre distances between the bores are repeated in each size.

Inventor: LINDNER GEORG HEINRICH
IPC: F04B53/10
Filed: 1984-12-21
Abstract: A positive displacement pump (310) utilizes at leastthree driven displacer valves (360,362,364) and a plurality of driving membranes (336,340,344) and at least one pumping membrane (316) to withdraw minute quantities of corrosive fluid from a drum (100) and discharge same to a delivery point (128). The pump (310) is submerged within the fluid to be pumped and is driven by a remotely positioned pneumatic pulse generator (116) comprising pneumatic logic circuitry. The driven displacer valves (360,362,364) operate in a particular sequence to draw fluid into the pump body (312,314), advance same in succession through pumping chambers (318,320,322) within the pump body (312,314), and then discharge same at a constant rate of discrete pulses through an outlet port (332). The pulse generator (116) and logic circuitry provide the control pulses for operating the displacer valves (360,362,364) at the proper times in the operational cycle. The delivery characteristics of the pump far exceed the performance capabilities of conventional pumps utilized for similar purposes.

Title: System for operating magnetic levitation vehicles
Inventor: VON KUEPACH HERMANN
IPC: B60L15/00
Filed: 1990-05-16
Granted: 1998-06-23
Abstract: A system for driving a vehicle by magnetic levitation includes a synchronous long-stator motor, with a long stator winding extending along a track of the vehicle and being subdivided into a plurality of discrete stator winding sections (3.11 to 3.19; 3.21 to 3.29).  The vehicle which is movable on the track supports fixedly mounted exciters cooperating with the stator winding sections.  At least one section cable (17, 28) is arranged parallel to a portion of the track and each of these ends is connected to a power sub-station.  The section cable has a plurality of consecutive tap points each being connectable via a switching device to an assigned stator winding section.  The switching devices are activated when the vehicle runs over the corresponding winding section.  To reduce power losses in the section cable, and also to reduce the number of stator winding sections for a given output power of the sub-stations and also to insure a uniform utilization of the available power over the entire track portion, there are provided control means which adjust the ratio of partial current delivered by the respective power sub-stations as a function of the momentary condition of the vehicle and/or as a function of the ratio of a distance (1) of progressively activated stator winding sections from one of the sub-stations, to the length (d) of the section cable between the two sub-stations.

Title: Apparatus for the threedimensional inspection of hollow bodies
Inventor: APTER ROBERT
IPC: G01N21/90
Filed: 1990-12-10
Granted: 1994-08-09
Abstract: A conveyor moves the hollow bodies over a circular path through an inspection region in which the hollow bodies are homogeneously illuminated by an illumination device. The light issuing from the hollow bodies passes via a group of four mirrors and a deflecting mirror to a matrix camera or line scanning camera.  The mirrors are plane mirrors which are inclined at an angle in relation to one another. The hollow bodies execute one complete revolution about their longitudinal axis while passing through the inspection region.   Therefore,  the group of four mirrors views a quarter of the circumference of the hollow bodies each time in succession.  The inspection apparatus is particularly suitable for inspecting the threaded region of bottles and has the advantage that it does not need any moving parts.

Inventor: YOSHIZAWA HIDEO
IPC: C03B35/16
Filed: 1991-01-10
Granted: 2001-05-08
Abstract: A glass sheet is heated nearly to its softening point while being passed through a heating furnace. The heated glass sheet is then clamped at its peripheral edge between first and second molds. Thereafter, a third mold is pressed against a central region of the glass sheet with the peripheral edge thereof clamped, thereby to project the central region from one side to the other side thereof. The glass sheet is thus pressed to a desired highly curved shape with no wrinkles or cracks developed therein. The glass sheet is clamped and pressed by a pressing apparatus which includes a fixed concave ring mold as the first mold, and a movable convex mold comprising a peripheral mold assembly as the second mold and a central mold member as the third mold.      The glass sheet thus curved is typically used as a front or rear window glass sheet for automobiles.

Filed: 1991-07-09
Granted: 1995-09-12
Abstract: An image data encoding system efficiently reconstructs an image through a progressive image buildup in stages.      An original image is divided into blocks each having NXN picture elements, whose transformation coefficients are obtained by orthogonal transformations on their graduated values.    The image data encoding system has a transformation  coefficient memory  for  storing transformation coefficients; a mask information memory for  storing  mask  information  for  masking transformation coefficients; a masker for masking the most significant bits of the transformation coefficients specified by mask information; a shift information memory storing quantization thresholds for quantizing the transformation coefficients; and a quantizer for quantizing the masked transformation coefficients per the quantization threshold.    The quantization threshold can be given a value of 2 to an integer power, and quantization can be attained by shifting bits of the transformation coefficients towards less significant bits by that power.
