Patent EP-0397492-A2 (EP)
Inventor: BROUSSARD JERRY A
IPC: C08G2/18
Filed: 1990-05-10
Abstract: Cationic copolymerization of trioxane and trimethylolpropane (TMP) formal or its ester derivatives yields acetal copolymers having pendant functional groups. The TMP formal or ester derivatives of TMP formal may therefore include functional groups selected from hydroxyl or ester moieties which are protected and this survive the copolymerization with trioxane. These groups may then be present as functional reactive sites for the subsequent synthesis of block copolymers and/or to chemically bind modifiers to the acetal copolymer backbone, for example.

Inventor: ALBERTSON WILLIAM CONRAD
IPC: F02B75/12
Filed: 1990-07-11
Abstract: An engine control system is disclosed for reducing the hydrocarbon content in exhaust gas from a crankcase-scavenged, two-stroke engine (10) in the operating range near idle, with light operator-­induced engine loading. As operator demand for engine output power is increased, the control system increases the fuel per cylinder delivered to the engine (10), whilst restricting the supplied mass of air per cylinder to a value less than or equal to that flowing at unloaded engine idle, in said operating range. This is done by coupling a throttle pedal (56) to a throttle valve (52) in an air intake manifold (20) through a pivoted linkage system (60,62,64,66,68,70,72,74) which includes a lost-motion connection (72,74), which prevents movement of the throttle valve (52) until a predetermined displacement of the throttle pedal (56) has occurred. A computer (48) of the control system controls the fuel supply per cylinder in response to signals (PED) received from a potentiometer (84) monitoring all mobement of the throttle pedal (56). The control system also may include an air bypass passage (76) and a computer-controlled, solenoid-actuated valve (78) to further control the supplied mass of air in said operating range.

Abstract: A retention device which can be removably retained in a body cavity or passage has branch members which are movably connected to each other such that two relative configurations may be obtained. In one configuration the branch members are nested inside one another for inserting the retention device in a cavity. Once in a cavity an operating member is used to displace the branch members to form the second configuration, being a diamond configuration in which parts of the branch members are resiliently expanded to bear against the walls of the cavity and retain the device.

Abstract: A graphical data presentation circuit and method which allows for tightly packing a video memory (130) without regard for the pixel size or number of pixels on a line of the graphic display. The memory output split-serial register (140) is used together with a counter (94) to maintain count of the currently executing output stage of the register (140). When a first half of the register (140) has completed transferring its data to the display it is cleared and reloaded with the first part of the next memory row. When the second half of the register (140) is likewise finished transferring its data it is also cleared and reloaded with the data from the second half of the memory row. This alternating operation allows for mid-row register refreshing without affecting data transfer performance.

Inventor: COLDEBELLA MARK
IPC: H01F7/18
Filed: 1991-01-11
Abstract: The control circuit of the invention consists of a solenoid which generates a high propelling force when the player closes a flipper switch. A primary timer circuit decreases the power when the flipper switch is held closed by a player for more than a predetermined length of time such that only a lower holding power is delivered. Thereafter, if the flipper begins to slip from its holding or static position, a sensor activates a maintenance timer circuit which again generates the higher propelling force. The maintenance timer circuit lowers the power after another predetermined length of time has expired. If the flipper again beings to slip, the maintenance timer circuit is reactivated and the cycle is repeated. Once the player releases the flipper switch, the solenoid is de-energized and both timer circuits are reset until such time as the player again depresses the flipper switch. In this manner, only the power necessary to maintain the desired mode of operation is delivered to the solenoid such that overheating and failure of the solenoid is avoided.

Abstract: In a cellular telephone network, subscribers each have a token (such as a smartcard) by means of which they respectively identify themselves to the network. Each subscriber logs into the network by using his smartcard which inputs a unique identification number (IMSI) into the network. The relationship between each IMSI and the corresponding subscriber's telephone number (MSISDN) is random and stored in a home location register (HLR). When a subscriber activates a mobile using his smartcard, a visitor location register (VLR) at the relevant cell cheks for presence of the IMSI and the corresponding MSISDN. If they are not present, it extracts them from the HLR. When a replacement smartcard is issued to a subscriber, the new IMSI is stored in the HLR in association with the IMSI of the previous smartcard. When the replacement smartcard is first used, the relevant VLR will note its absence and will follow the same routine as specified above - by accessing the HLR. Not only will it thus obtain and store the MISISDN for the subscriber in association with the IMSI of the new smartcard, but this will also activate the HLR to note first use of the replacement smartcard, cancel all reference to the IMSI of the previous smartcard, and inform the administration centre of the network.

Abstract: The invention relates to reservoir evaluation and is more specifically directed to a method of characterizing the individual response of a layer of a multi-layer hydrocarbon reservoir traversed by a well, based on downhole flow rate and pressure measurements performed during transient tests initiated by changes in the surface flow rate of the well, the flow rate being measured above said layer during one transient test and below said layer during another transient test. The variations of downhole pressure and flow rate with respect to their respective values at the initiation of the transient test are determined, each of said flow rate variations is normalized by the pressure variation after the same time interval within the same transient test, thereby to produce a first pressure-normalized flow rate function for the level above said layer and a second pressure-normalized flow rate function for the level below said layer, and said first and second pressure-normalized flow rate functions are subtractively combined to generate a function representative of the individual response of said layer.

Abstract: A memory system that provides extra data bits without utilizing storage capacity. A first data word is fetched from memory (10) and corrected to remove any single-bit errors. A second data word (which is a subset of the first data word as corrected) is then fetched, and new data correction bits (parity or ECC check bits) is generated for the second data word. Both the second data word and the newly-generated data correction bits are output. This structure amortizes the expense of in-system data correction over a greater data output, and over a smaller storage capacity relative to the data output.
