Patent GB-2370016-A (GB)
Title: Maintaining an inkjet printhead by applying a pressure pulse to ink within the head wherein the pulse has a rising leading edge and a trailing falling edge
Inventor: BROWN STEVE
IPC: B41J2/165
Filed: 2001-10-05
Abstract: An apparatus which maintains an inkjet printhead 1 in a working state is disclosed. The apparatus comprises a controlled valve 21 for applying a pressure pulse to ink within the printhead sufficient to discharge ink from each orifice when not in use to project ink. During purging, a valve 8 is opened to establish an air flow across an orifice plate, and the valve 21 is opened to apply a positive pressure to ink in a supply 14, causing ink to be discharged from orifices (3,Fig.1) onto a plate 2. This ink is then displaced by the air flow and gathers in a gap (9,Fig.2). The air flow is then cut off and the printer is ready for the next cycle. The pressure pulse (Fig.4) has a rapidly rising leading edge and a slowly failing trailing edge, which ensures that contaminants are dislodged from the jets and yet there is minimal risk of the jets becoming de-primed when the pulse is terminated. The pressure may be applied through a valve which is switchable between a first condition in which a compressed air source 22 is connected to the supply, and a second condition in which the supply is connected to an exhaust conduit 23 which communicates with the atmosphere via an airflow restrictor valve 24.

Title: Self cooling a can or container
Inventor: MOLZAHN STUART WILLIAM
IPC: A23G9/00
Filed: 1998-09-21
Abstract: A self-cooling beverage or foodstuff can or container comprises a chamber (30) including water (26) and carbon (28) as an absorbent. The water and carbon are separated by a burstable membrane (42). When cooling is required, a push button (36) urges a cutter (38) to break the membrane (42). Water vapour is then absorbed by the carbon, lowering the pressure, and causing more water to evaporate to replace the adsorbed water. This cools the body of water, and hence the beverage or foodstuff. The wall near the absorbent may be of an insulating material to prevent a consumer from experiencing heat created by the absorbent material.

Title: Reduced instruction set for java virtual machines
Inventor: SOKOLOV STEPAN
IPC: G06F9/455
Filed: 2002-03-27
Abstract: Techniques for implementing virtual machine instructions suitable for execution in virtual machines are disclosed. The inventive virtual machine instructions can effectively represent the complete set of operations performed by the conventional Java Bytecode instruction set. Moreover, the operations performed by conventional instructions can be performed by relatively fewer inventive virtual machine instructions. Thus, a more elegant, yet robust, virtual machine instruction set can be implemented. This, in turn, allows implementation of relatively simpler interpreters as well as allowing alternative uses of the limited 256 (28) Bytecode representation (e.g., a macro representing a set of commands). As a result, the performance of virtual machines, especially, those operating in systems with limited resources, can be improved by using the inventive virtual machine instructions.
