In particular, the revision knee implant, comprised of a femoral component having incremental markings thereon and a femoral stem, and corresponding cutting block system having corresponding incremental markings thereon, enables a surgeon maximally to position the cutting block adjacent as much area as possible of a distal femur of a patient and to infinitely position the femoral component in the exact position indicated by the cutting block.

Abstract: A backup power supply for a telephone set that does not use batteries comprises a Electric Double Layer Capacitor (“EDLC”) having a charge capacity sufficient to power the control electronics of the set in the event of a power failure and for the brief period of time necessary for the telephone to go off-hook and thereby draw sufficient power from the local loop of a Telco or PBX to place or receive voice calls and recharge the EDLC. The power supply includes circuitry for detecting an incoming call or an instruction to place an outgoing call during a power outage, and for responsively coupling the power of the capacitor to the electronics of the set so that the set can receive or place the call. The power supply further includes circuitry for recharging the capacitor rapidly from both the conventional power supply when it is functioning and from the local service loop when it is not.

Abstract: A tibial implant is provided having a stem, a tray, a bushing for joining the stem and the tray, and a locking member. In use, the stem of the implant is inserted into the medullary canal of a natural tibia and the tray rests on a resected surface at the proximal end of the tibia. The tray includes a central position and an engagement portion on a lower surface thereof. The bushing includes a proximal axis of alignment in alignment with the central position of the tray and a distal axis of alignment that is co-linear to the longitudinal axis of the stem. The engagement portion of the tray is comprised of a dovetailed ring member. The bushing also includes, on a proximal end thereof, an engagement surface having first and second pairs of surfaces for, respectively, passage through the opening of the ring member and sliding complementary engagement with the dovetailed ring member.

Abstract: A security bag includes an electronic memory device which may be read remotely using non-visual means. A method of processing such a bag comprises the steps of encoding information onto the tag in non-visible form, retaining the device on or in the bag, and subsequently retrieving the information. A variant provides the memory device of the electronic tag and the electromagnetic or inductive coil being separately located and connected across the seal of the bag by a conductor designed to break upon attempted opening of the bag.

Abstract: A tape or label for sealing a container that provides visual evidence if the seal is forced open or cooled below a breakdown temperature. The tape includes a plastic strip, a layer of ink printed on a surface of the plastic strip, and a layer of pressure-sensitive adhesive. The tape can be incorporated into a bag for sealing the bag closed. The tape includes an ink layer that is sandwiched between the plastic strip and the adhesive layer. The adhesive can be secured to portions of a bag to seal it closed. If the seal is forced open, the ink layer visibly delaminates from the plastic strip. The adhesive layer and the plastic strip are chosen to have different rates of shrinking when cooled, so that when the tape is cooled below its breakdown temperature, the ink layer delaminates. In an alternative embodiment of the tape, two layers of ink are printed onto the plastic strip. The first layer of ink is clear and is printed onto the untreated plastic strip in a pattern.

Abstract: A system for communicating to a fisherman information relating to fish in water in the vicinity of a fishing lure or hook which is connected to a conventional non-electrically conducting fishing line and which includes a float attached to a conventional non-electrically conducting fishing line with the float being located at or below the water surface. The system also includes a sensor housed in the float for detecting a parameter relating to the fish, the sensor being housed in the float. Also housed in the float are an electronic card and a transmitter for wirelessly transmitting the signal. A power source housed in the float provides electrical energy to the sensor and transmitter. The system also includes a receiver for receiving the signal from the transmitter and a display or other output for presenting information relating to the signal to the fisherman.

Abstract: A gas indicator (11) for a modified atmosphere food package (19) comprises a series of strips (12, 13, 14, 15, 16) which progressively change colour as the proportion of carbon dioxide in the atmosphere progressively changes in magnitude due to absorption of the carbon dioxide by the food product (17) over time. The indicator (11) thus is "tuned" to indicate changing atmospheric conditions inside a see-through envelope (10) and thus the condition of the product (17) can be monitored and the package (19) is tamper evident.

Abstract: A security bag for storing and transporting valuable articles includes an upper pouch and a lower pouch that are not overlapping that prevents unauthorized parties from entering one pouch and hiding such entry with articles in the other pouch. The upper pouch and the lower pouch open at upper ends of the respective pouches. The security bags are useful for storing and transporting currency and negotiable instruments or receipts.

Abstract: Liquidtight containers which are so integrated at the upper ends thereof as to keep fluids from escaping through the gaps between the front and back walls of the container. The closure system of the bag is designed to surround the upper end of the bag with adhesive when the bag is sealed so that fluid cannot escape between the main part of the bag and the closure. The closure system can also be designed so that an attempt to open the bag and then reseal it will be readily evident.

Abstract: An improved optical inspection apparatus, especially suited for inspecting semiconductor devices using a single camera. A highly polished mirrored stage is provided with a light source extending upwardly therethrough and providing a pedestal upon which the object to be inspected is centered. A plurality of stationary reflectors are disposed around the stage and function in concert with two separate movable reflectors to provide optical scanning over the appropriate surface portions of the device. A separate movable reflector system is used to maintain a constant focal path length between the device and the camera as the other movable reflectors scan the device, thus ensuring proper focus and measurement accuracy.

Abstract: A method for sinking a shaft having a wide diameter e.g. 4 meters. A concrete diaphragm wall is formed with five radially inwardly extending sections (12), in each of which a guide hole (13) is formed. Five outer boreholes are drilled to depth using the guide holes and a central borehole (14) is also drilled to depth. The ground within the wall is excavated to rock level. Vertical cuts are made between adjacent outer boreholes (14) and between the central borehole (14) and the outer boreholes (15) using a wire (19) saw cutter. Cross cuts are then made to form separated segments (33) of rock which are removed sequentially. This is repeated progressively downwards to the required depth.

Abstract: A packaging method and apparatus are disclosed in which a substantially horizontal bed is loaded with a series of independent magazines. Each of the magazines supports a plurality of open trays which are loaded with the desired contents. The magazines are moved along the bed to a vacuum chamber where a cover film is applied and the magazines are independently supported. The vacuum chamber is then closed to allow for evacuation and sealing of the covered trays and the magazines supporting the finished packages are removed from the vacuum chamber.

One of the heads of each pair includes a stop projection. Electrical actuators and associated mechanical linkages are provided for sequentially moving the heads of each pair toward each other in steps from maximally separated positions to intermediately separated positions wherein the stop projections intrude into the path taken by devices moving along the track and thereby define a device test location, and then to minimally separated positions wherein the contactors of each head engage the connector legs or pads of a packaged device disposed in the test location.
