Title: Randomised fat compositions for infant food formulae
Inventor: LIEN ERIC LOUIS
IPC: A23L35/00
Filed: 1991-11-29
Abstract: The invention disclosed herein comprises fat compositions primarily for use in nutritionally complete infant formulas in which the constituent palmitic acid oils and lauric acid oils are corandomized. The invention additionally includes such corandomized fat compositions with medium-chain triglycerides added, particularly for use in nutritional products for preterm or low birthweight infants. Such corandomization of two or more oils yields a mixture of triglycerides having a substantially different chemical makeup than that of the native oils themselves or than the native oils when randomized individually. Corandomization of the palmitic acid oils and the lauric acid oils affords an economical means of providing a very highly absorbed fat composition.

Title: Gas supply pressure control apparatus
Inventor: YONNET CLAUDE
IPC: G05B19/07
Filed: 1992-01-21
Abstract: The pressure of gas in a gas main 10 is controlled according to one of a number of pressure profiles stored in electric controller 28, to provide an appropriate pressure for the time of day, day of the week, season of the year etc. Electrically operated valves 56, 58 place a command value on line 29 representing the current desired profile pressure. Pilot governor 18 regulates the flow in auxiliary gas line 12 accordingly, which in turn, through inspirator 20 controls the pressure in the main gas line 10. A feedback pressure in line 11 also acts on pilot governor 18. The electronic system monitors, at 13 and 15, the upstream and downstream pressures for data logging, to monitor adherence to the pressure profile, to update the shape of the pressure profiles and to switch from one profile to another if certain criteria are met. <IMAGE>

Title: Inflatable borehole plug.
Inventor: ROBBINS GEOFFREY
IPC: F42D1/18
Filed: 1992-12-24
Abstract: The invention relates to inflatable plug assemblies and to means to control the time required for their inflation. In particular the invention enables inflatable borehole plug assemblies to be lowered to a preselected depth in a borehole before inflation occurs. The inflatable borehole plug assemblies of the invention comprise a sealed gas-tight inflatable container (1) containing a pressurised vessel (2) having pressure releasing means (7). The pressurised vessel (2) contains an inflating substance (4) and a time delay liquid (5), and is adapted so that on operation of the pressure releasing means (7): (i) the time delay liquid (5) is discharged from the pressurised vessel (2), thereby causing a time delay between the operation of the pressure releasing means (7) and release of the inflating substance (4) from the pressurised vessel (2), and (ii) after the time delay liquid (5) has been discharged the inflating substance (4) is discharged, thereby inflating the inflatable container (10) to form a borehole plug. <IMAGE>

Title: Panel-form loudspeaker
Inventor: HERON KENNETH HARRY
IPC: H04R7/06
Filed: 1993-01-27
Abstract: A panel-form loudspeaker has a resonant multi-mode radiator panel which is excited at frequencies above the fundamental frequency and the coincidence frequency of the panel to provide high radiation efficiency through multi-medal motions within the panel, in contrast to the pistonic motions required of conventional loudspeakers. The radiator panel is a skinned composite with a honeycomb or similar core and must be such that it has a ratio of bending stiffness to the third power of panel mass per unit area (in mks units) of at least 10 and preferably at least 100.

Title: Adaptive prosthesis control system
Inventor: ZAHEDI MIR SAEED
IPC: A61F2/70
Filed: 1994-05-27
Abstract: An adaptive control system for an artificial limb has a piston and cylinder assembly 18 for controlling knee joint flexion, an electronically driven motorised valve 18D for varving the damping effect of the assembly, a proximity sensor 24A, 24B for sensing knee flexion, and a processor circuit 22 for mounting on the limb. The system also has a radio receiver connected to the processor circuit and an operator control unit for remote transmission of command signals to the receiver. In a teach mode, the system allows an operator to increment the valve opening by remote control to optimism operation of the limb, and to cause the processor circuit to record selected valve openings in conjunction with average step period values which are produced automatically by the system during use of the limb. Recording a new selected valve opening causes the processor circuit on the limb automatically to calculate a set of control data relating valve openings to walking speed ranges. This set of control data is used in a playback mode of the system for automatically adjusting the valve opening during normal use of the limb according to the speed of the limb operation. <IMAGE>
