Title: Ferrimagnetic core materials for megahertz frequency high flux density transformers and inductors
Inventor: VARSHNEY USHA
IPC: C04B35/26
Filed: 1992-09-11
Abstract: An NiZnCo ferrimagnetic core material may further contain elements from the group Cr, Mn or Li. These materials permit enhancement of magnetic properties and results in core materials capable of efficient operation at high frequencies on the order of 1-100 MHz over a wide range of magnetic flux densities, on the order of 1-2500 Gauss. The composition of base NiZnCo ferrites is adjusted through ionic substitution. Alternatively, the magnetic properties of the said core material are enhanced through Fi2Q3 and SiO2 additions and controlled sintering.

Title: A fitment for inhibiting refilling of a bottle
Inventor: HARBUTT RICHARD PAUL
IPC: B65D49/02
Filed: 1992-11-12
Abstract: A fitment for inhibiting the refilling of a bottle comprises a one-way valve 5 to allow outward flow of liquid and to prevent unauthorised refilling of the bottle 1 and vacuum break, gravity operated valve 2 4 to allow air to pass into the bottle 1 when a partial vacuum exists in the bottle 1, separate liquid and air passage means 6, 7 being provided. The one-way valve in the liquid passage may be a flap valve, a ball valve (Figures 17 - 19), a disc valve (Figure 16), an umbrella valve (Figures 20 - 22) or film and grid valve (Figure 22), and a weight may be provided to slide into and out of contact with the valve (17, Figure 3). The vacuum break valve comprises a float member 2, a weight member 4 and a sealing member 3 for sealing an air inlet 9. The weight member has an offset centre of gravity to ensure sealing member 3 seals inlet 9 when the bottle is in a horizontal position, inversion of the bottle through at least 120 DEG being needed to unseal inlet 9. If liquid is introduced into air passage 7 float member 2 will be lifted and cause sealing member to seal inlet 9 and block introduction of further liquid. The float and weight members may form an integral member of neutral buoyancy (Figure 12), the float and sealing members may be integral or the weight and sealing members may form a unit (Figure 11). <IMAGE>

Title: Clutch control preventing engine racing on downshift
Inventor: SCHMITZ HARALD
IPC: B60W50/02
Filed: 1993-08-27
Abstract: To prevent a motor vehicles engine being forced over its speed limit as a result of erroneous selection of a too low a gear during gear changing while still providing engine braking, a clutch between engine and gearbox is caused to slip. The clutch, mounted between the engine and a gearbox, is automatically engaged/disengaged by a setting member controlled by a micro-controller which immediately disengages the clutch when a gear shift lever is operated. Upon engaging a new gear, synchronization commences during which the gearbox speed is monitored so that if a predetermined speed threshold is exceeded the disengaged clutch is engaged with a predetermined adjustment speed up to its engagement point. The amount of engagement, beyond the initial engagement point is continuously adjusted by altering the ideal clutch stroke, which is continuously calculated by using an algorithm, until the speed does not exceed the predetermined speed threshold.
Patent GB-2270769-A (GB)
Title: A tensile testing device.
Inventor: THORSEN HELGE
IPC: G01N3/00
Filed: 1993-09-17
Abstract: A hydraulically driven, dynamic tensile testing device in which a test sample (2) attached to an underlying surface (1) can be secured to the device and subjected to tensile forces when the device is raised from the underlying surface. The device rests against the underlying surface on three or more legs connected to interacting pistons (6). The interacting pistons are preferably hydraulic pistons that are pressurized by means of hydraulic fluid which is distributed through interconnected ducts in such a way that the legs have a constant, even pressure. The device thus ensures that the tensile forces are evenly distributed on the cross-section of the test sample, and is particularly applicable to testing adhesion of coatings such as paints, or testing materials having little elasticity. <IMAGE>

Filed: 1993-12-16
Abstract: A fuel flow control system in a motor vehicle comprises a solenoid-actuated valve mounted in a fuel line, in which the valve member can be held in positions preventing and allowing fuel flow. The valve member may take the form of a magnetic plunger 20 located in a fuel flow channel 13, 15, urged open by a spring 21, with magnets 22 positioned to bias the valve closed. The valve is opened by a control unit (figure 2, not shown) when a code is entered via a keypad. Entering the wrong code will cause an alarm to sound. The valve is closed by the control unit after the engine of the vehicle is switched off, or if an impact is sensed. The control unit may send pulses to the valve while the engine is running to ensure that the valve does not stick in place. The code may be entered using an infra-red remote control unit. <IMAGE>

Title: Supporting real mode card services in a protected mode implementation
Inventor: SANDAGE DAVID A
IPC: G06F13/10
Filed: 1994-07-04
Abstract: PCMCIA defines a standard interface for small portable computer peripherals. The current PCMCIA specification defines a Card Services layer that provides Card Services to clients that wish to use PCMCIA cards. A Card Services Compatibility Driver is defined that ensures compatibility with real mode clients. The Card Services Compatibility Driver is a device driver or TSR that loads near the beginning of the computer system boot procedure. The Card Services Compatibility Driver simulates a full implementation of Card Services by supporting only the functions that are legal when no cards are installed in the system even though cards may be installed in the system. Later, a full protected mode implementation of Card Services is loaded into the system. The Card Services Compatibility Driver transfers all the state information it collects during the computer system boot procedure to the full protected mode implementation of Card Services. Alter receiving this information, the full protected mode implementation of Card Services takes control and services all later Card Services requests. The full protected mode implementation of Card Services also informs the registered Card Services clients of any cards inserted in the system by making card insertion callbacks. <IMAGE>

Title: Process for reducing premeability in a high-temperature subterranean hydrocaronbearing formation utilizing a decarboxylated crosslinking agent
Inventor: SYDANSK ROBERT D
IPC: C09K8/512
Filed: 1994-09-22
Abstract: A process and composition are provided for permeability reduction in a hydrocarbon-bearing formation to improve hydrocarbon recovery therefrom. The process includes placement of a crosslinked polymer gel in the treatment region preceded by surface preparation of a gelation solution from which the gel is formed. The gelation solution contains a crosslinkable polymer, a transition metal/poly-carboxylate precursor complex and an aqueous solvent. The gel is placed in the treatment region by injecting the gelation solution into a well bore in fluid communication with the formation, activating the gelation solution in situ, displacing the gelation solution into the desired treatment region and gelling the solution to completion forming the permeability-reducing gel in situ. The gelation rate is retarded in a controlled manner by adjusting the molar ratio of the poly-carboxylate to transition metal in the precursor complex of the gelation solution.
