Title: Foodstuff
Inventor: HALL SIMON REGINALD
IPC: A23J1/00
Filed: 1988-09-29
Abstract: Textured animal protein can be prepared by forming a heated pressurised wet mass of animal meal and extruding the mass or otherwise reducing the pressure and temperature surrounding the mass. The ingredients for the animal meal are chosen so that the measurable gelatin content of the extruded product is less than 10% of the dry solids of the product. As gelatin is a hydrolysis product of collagen, this means that the animal meal should be prepared from material which is intrinsically low in hydrolysable collagen, or the hydrolysable collagen content should be reduced either by cross-linking (for example with propylene glycol alginate) or by hydrolysis and washing away the gelatin.

Abstract: An application memory card system includes a secure memory card which can be operatively connected to communicate with a host mainframe microprocessor or hand held device host microprocessor via a standard interface. The secure memory card contains an application processor and an access control microprocessor (ACP), each of which connect through an internal bus to a number of non-volatile addressable memory chips, each organized into a plurality of blocks. Each microprocessor has an additional control signal line included in a control bus portion of its bus for specifying "Execute" access. An access discrimination logic unit which connects to the internal bus and to the non-volatile memory includes an access by type memory writable by the application processor under the control of the ACP for maintaining security. The access discrimination logic unit combines the "Execute" control access signal from a microprocessor with a signal designating the microprocessor source (e.g. external or internal) to define the type of memory access requested and transfers a control enabling signal as a function of the state of the selected stored access control bit indicating if the requested access is allowed to the addressed block.
