Patent CA-2059661-A1 (CA)
Title: Relating to cutting apparatus
Inventor: WOOD ERIC
IPC: B24C5/02
Filed: 1990-08-06
Abstract: The invention provides cutting apparatus which is in the nature of a high pressure jet cutter. Water (16) at high pressure is supplied to a mixing head (14) and also supplied to the mixing head is a suspension (18) including abrasive particles, the particles being held in the suspension. The respective components are fed to a mixing head at different speeds, the water at high speed and the abrasive suspension at slow speed. The suspension is accelerated to match the water speed in the mixing head to ensure mixing.  The advantage of the arrangemet is that if the supply of materials to the jet cutter is stopped, the abrasive particles remain in suspension and do not settle out so that the apparatus can be restarted without difficulty. The invention also provides a mixing head enabling the above to be achieved.

Title: General-purpose memory access scheme using register-indirect mode
Inventor: CHUANG CHIAO-MEI
IPC: G06F12/02
Filed: 1992-01-23
Abstract: ABSTRACT      A  memory  access  scheme  achieved  using  a  memory address register and a register-indirect memory accessing mode eliminates write back collisions,  long cycle time, and enhances system performance.  During memory address generation  operations,  an  arithmetic-logic  unit  (ALU) generates memory addresses from data in a general purpose register (GPR).  Then, the memory addresses are written back to the GPR and a memory address register  (MAR). During memory access operations, the MAR is accessed for the memory addresses to access a memory.  Two approaches are provided.  In a first approach, use of the MAR during the memory access operations is explicit.   In a second approach,  use  of  the  MAR  during  the  memory  access operations  is  transparent.   According  to  the  second approach,  a controller is provided to validate the MAR during the memory access operations.

Filed: 1990-07-10
Abstract: A disposable hypodermic syringe is disclosed having a barrel (4), a hub (1) and needle holder (2) locatable on the barrel, a plunger (5) with a piston (13) at one end thereof slideable within the barrel, and an interlockable structure on the plunger and needle holder for interlocking the same one relative to the other so that after use the needle (3) is fully retractable into the syringe barrel (4) to prevent accidental stabbing and risk of infection.  The needle holder tube (2) has internal barbs (10) which engage behind a domed head (8) of the plunger (5). During use (suction and injection delivery) the plunger domed head (8) is retained behind a membrane (14) within the piston (13) by similar internal barbs (20) inside the piston (13). Preferably the interconnection between the needle holder (2) and hub (1) is a screw thread and the plunger is rotatable to detach the needle holder (2) and needle from the hub. In one alternative form the needle (3) is supported in the needle holder (2) by a weakened structure breakable by axially applied pressure upon the piston rod (5). The weakened structure (44) is generally of a thinner molded thickness than the remaining moulding and is further weakened by Gamma Irradiation or other electron beam.

Title: Drip-catcher
Inventor: JENSEN BRIAN VANG
IPC: B65D5/74
Filed: 1991-09-17
Abstract: The invention relates to a drip-catcher for, for instance, a bottle and intended for preventing dripping and drops seeping from the bottle orifice during pouring. The drip catcher of the invention simply consists of a piece (1) of flexible and elastic foil material, preferably plastic material foil having the thickness of .1-.2 mm. The diameter of the piece of material may be 60-80 mm. When used as a drip-catcher the piece of material is rolled into an oblong cylindrical form andinserted in the orifice of the bottle. Due to its elasticity the piece of material will positively engage the orifice and constitute a tube-formed outlet spout. Due to the          (see fig. I) small thickness of the foil material and its liquid-repellent nature this spout cuts off the jet very efficiently and is also a very efficient drop-catcher. The drip-catcher of the invention is extremely simple and cheap. Its use is uncomplicated and it is universally applicable because the piece of material adjusts itself to the bottle orifice irrespective of its size. The effect of the drip-catcher is remarkable due to the small thickness and liquid-repellent surface of the material.
