Title: A safe shutdown device and a method of controllably shutting down a system
Inventor: GOODFELLOW JOHN
IPC: G01M7/02
Filed: 2005-05-06
Abstract: There is described a safe shutdown device and method, for example, for use with a vibration test system for testing automotive or aeronautical equipment by subjecting the equipment to shock and/or vibration testing. As the system and equipment are expensive it is important they are not damaged during testing. In the event of a fault occurring uncontrolled energy dissipation can give rise to excessive forces being generated that exceed the specification of the equipment under test or the vibration test system itself. The invention achieves a safe shutdown of the test system by switching energy in a controlled manner and rate to an energy sink, thereby bringing about a rapid and safe arrest of the vibrating system and any associated dynamic parts. This is achieved by sensing a non-standard state in the system and controllably switching and diverting energy to a variable load so as to eliminate the risk of damaging the system or test equipment.

Abstract: The invention is a method of forming a box from a substantially rectangular blank characterised by the step of making at least one re-entrant fold parallel to two edges of the blank then folding the blank along fold lines parallel to the other two edges so as to form a tube. The other two edges of the tube overlap and one end of the re-entrant fold at one edge engages with the other end of the re-entrant fold at the other edge. The reentrant fold may form an inwardly extending flange inside the tube. The invention is also a blank for forming a box by the method the blank having indications where the folds must be made, and a box formed from a substantially rectangular blank having re-entrant fold parallel to two edges of the blank and formed as a tubular structure whereby the other two edges of the blank overlap and the re-entrant fold on one edge interlocks with the re-entrant fold on the other edge. Preferably the blank is formed without any cuts in it.

Title: Slotted, flexible shaft for an endoscopic instrument
Inventor: LYONS EDWIN
IPC: A61B1/005
Filed: 2008-01-04
Abstract: A shaft 1 for an endoscopic instrument has two series of slots 5 and 6 forming a preferentially flexible portion 2. The series are offset and the length of the slots varies along at least one of the series to vary the flexibility of the shaft. Bending initiates in the most flexible part of the shaft and migrates laterally along the line of shortening slots. The length of the slots may oscillate within a single flexible portion so that bending initiates in more than one place. The slot length may vary such that the ends of the slots are joined by a straight line at an angle to the longitudinal axis of the shaft (figure 2). Slots of one series may, in places, be long enough to overlap with those of the other series. Bending of the shaft is achieved by the movement of control wires attached to the flexible portion.

Where the wafer is only partially diced in the dicing step, dies are singulated from the wafer by etching remaining semiconductor material in the die lanes during the etching step. Spontaneous etchants which may be used include noble halogens, halides, halogen compounds and interhalogen compounds.

Title: Gearbox with cogs connected to shafts by integral gerotor pumps
Inventor: SMITH STUART PAUL
IPC: F16D31/04
Filed: 2008-07-25
Abstract: A gearbox may comprise a layshaft and a mainshaft having a number of cogs containing an integral gerotor type oil pump which locks together or unlocks two separately revolving parts, e.g. a hub and main body, of the cog thereby facilitating a connection or disconnection of the cogs to or from the mainshaft. The main body of the cog has a ring gear set inside it, offset from a centre, which mates with teeth on the hub, thereby providing the gerotor pump. In use when a clutchless gear change is initiated, a selector hub of an opposing gear is pushed by a fork into mesh with dog teeth of the hub, thus locking the hub to the mainshaft. When this is done oil is pumped through drillings of the opposing gear. Continuing across the opposing gear, the fork now inserts its collar under a step of another gear body, cutting off drillings and locking body and hub together, drive is now transmitted through this gear.

Abstract: 629,907. Sawtooth generating and valve amplifying circuits. SCOLES, G. J., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd- April 17. 1947, No. 10239. [Class 40 (vi)] In a circuit for increasing the effective impedance presented by a resistor to a circuit element in series with it, the junction is connected to a cathode follower, the cathode of which feeds tapping points on the resistor over coupling capacities. The potential across the section of the resistor nearest the junction is thus maintained substantially constant and presents a high effective impedance. A capacitor C1, discharged over device S is charged over resistors R1, R2, and R3, the rise in grid potential of valve V1 being fed back over coupling capacitor C2 and C3 to maintain the potential across resistor R1 substantially constant. In a modification, Fig. 3 (not shown), separate cathode followers are used for each valve. The resistor chain R1, R2 and R3 may form the anode load of an amplifying valve, Fig. 2 (not shown).
