Patent CA-2023440-A1 (CA)
IPC: G06T9/00
Filed: 1990-08-16
Abstract: This invention relates to a transform coding apparatus where linear transform is performed for input signal series such as image signals, and transform coefficients are quantized from lower frequency compo-nents to higher frequency components in the transform region, and then the quantized transform coefficients are coded and outputted. The quantized transform coefficients being zero are counted, and when the count value exceeds the prescribed threshold value, the quantization is terminated so that high speed in the coding is intended and variation of the code generation rate can be prevented.

Title: Video panning system for widescreen television
Inventor: ISNARDI MICHAEL A
IPC: H04N5/262
Filed: 1990-10-11
Abstract: RCA 85,762 Abstract of the Disclosure A widescreen television system compatible with a lesser aspect ratio standard television system employs a panning operation using a circular-shift method to keep a 4x3 aspect ratio panning window (area of primary interest) centered for display purposes. Illustratively, when the panning window is shifted left by a given amount at the widescreen signal source, a corresponding portion of right sidepanel image information is "cut" and "pasted" alongside left sidepanel image information so that the panning window remains substantially centered with respect to side panel information. A reverse cut-and-paste operation is performed at a widescreen receiver to restore the original widescreen spatial format. A standard 4x3 aspect ratio receiver processes and displays the centered panning window information normally, unaffected by the panning operation at the widescreen signal source.

IPC: F16H61/02
Filed: 1991-06-05
Abstract: SERVO SHIFT CONTROLLER FOR A FORWARD/REVERSE MECHANISM            Abstract of the Disclosure A mechanical clutch is provided to selectively interconnect a forward or reverse gear member to a transmission shaft.  The clutch is operated by a servo piston and fork structure.  The servo piston is slidably disposed in a housing and urged in the forward select position by a spring.  The housing and servo piston cooperate to define two fluid chambers which are maintained in a separated condition when the forward select position is established.  One chamber is in fluid communication with a fluid system that is controlled to provide fluid at two distinct pressure levels, depending upon various vehicle operating parameters.  The other chamber is connected with a selectively engageable fluid operated friction clutch which is effective to assist in establishing at least the reverse drive ratio within the transmission.  The lowest level of fluid pressure in the one chamber is not sufficient to cause the piston to overcome the spring force and thereby move the clutch to the reverse select position.  The second pressure level is, however, sufficient to cause such movement.  In the reverse select position, the chambers are fluidly interconnected and the fluid clutch can be engaged by the fluid pressure supplied through the second chamber from the first chamber.

Abstract: METHOD AND STORAGE TANK SYSTEM FOR ABOVE-GROUND FUEL STORAGE OF FLAMMABLE LIQUIDS Inner and outer welded steel protective tanks are separated by a space containing a granular insulating material such as perlite preventing excessive heating of fuel in a storage space in the inner tank, even when there is a fire at the site. The inner tank may be subdivided into portions by a partition defining a storage space and an overfill containment space receiving overflow from the storage space portion, with a sensor detecting overflow. The overflow containment space is also arranged to collect separated fuel when the tank system is used with a vapor recovery system. The granular insulating material acts as an explosion suppressant by dissipating heat and fuel vapors which may be present in the insulation space as a result of leakage from the inner tank. A triple walled tank of increased reliability against spills and penetration resistance is provided by a two closely spaced inner tanks within the insulation. Insulated tank saddles provide fire protection for the tank support.

Abstract: A cleaning cassette for cassette tape recorders comprises a cleaning member which upon placing the cassette in the tape recorder is brought into engagement with its recording/reproducing head and which through a transmission device is connected with an effective coil drive shaft in the tape recorder so as to impart to the cleaning member by the rotation of the coil drive shaft a reciprocating sweeping movement across the sound head. The transmission device includes two mutually engaging driven gear-wheels (14, 16), one of which carries the eccentric head (8) which by means of a pivot arm (5) imparts to the cleaning member (1) the reciprocating cleaning movement. Said driven gear-wheels (14, 16) are arranged so as to be applicable in a one-way coupling connection with a first and a second pinion (12, 13), resp., individually mounted axially displaceable on a threaded hub means (10, 11) in engagement with a coil drive shaft, thereby allowing displacement between positions in wich the pinion (12, 13) is in engagement and out of engagement, resp., with the actual driven gear-wheel.  Irrespective of which of the hub means (10, 11) is connected with the effective main drive shaft a correct cleaning function is obtained without establishing through the cleaning cassette any drive connection to the second hub means.

Filed: 1990-10-25
Abstract: A two-staged process for producing acetylene and calcium chloride from calcium carbide (12) and water (12) has two successive reaction steps. In step Number 1, calcium carbide is charged into an entrained flow-type reactor (10) vessel containing water. The reaction which follows proceeds to about 60-90 % completion. The entrained reaction products and the unreacted feed material are carried over to a secondary reactor (16) to complete the reaction, and the acetylene gas is drawn off (26). Calcium hydroxide product is removed from the reactor (23) and reacted with hydrogen chloride to form calcium chloride. Heat generated by the exothermic reactions of water with calcium carbide and HCI with calcium hydroxide is used to dry the calcium chloride product and improve its value. In the presence of excess of water, the calcium carbide-water reaction is effectively a first order, irreversible reaction.
