Abstract: A child resistant tap has a valve body (12) with an inlet (22) and an outlet (24) and a valve seat (26) therebetween. An axially slidable valve element (28) engages the valve seat (26) to open and close the valve. A handle or lever (1) is pivotally connected to the valve element (28) outside the valve body. The handle has a fulcrum portion (1-2), so that pivotal movement of the handle (1) operates the valve element (28). A safety lever (6) is pivotally attached to the handle (1) and has a locking arm (6-2) which engages the valve body (12) to prevent the handle from pivoting to open the valve. The safety lever (6) also has an actuator arm (6-1) located adjacent to a transverse lever arm (1-1) of the handle, so that squeezing together of the actuator arm (6-1) and the handle lever arm (1-1) causes the safety lever (6) to pivot out of engagement with the valve body (12) allowing the valve to be opened.

Abstract: An apparatus and method for providing a dynamic mapping of channel numbers to physical frequencies for some cells of a cellular telephone system, for use in case of a cellular telephone system representing physical frequencies by channel numbers and providing a fixed mapping of channel numbers to physical frequencies. The method includes a step of providing an information element indicating the dynamic mapping, and is performed in a way that is compatible with an existing channel numbering space, thereby keeping unchanged any existing signaling messages. The method also provides for a change in a dynamic mapping: a duplicated mapping is broadcast in which two non-overlapping sets of channel numbers are both mapped at least in part to a same frequency block, the broadcasting being continued for a predetermined time assumed to be of sufficient extent that any mobile phones operating in the cells will have decoded the duplicated mapping.

Title: Apparatus for recording a physical impression of an object down an oil well
Inventor: BALDWIN RUSSEL HUBERT
IPC: E21B47/09
Filed: 2003-07-07
Granted: 2008-11-25
Abstract: A reusable apparatus for making a physical impression of an object lodged down an oil well. A rod support is positioned in a housing. A plurality of rods are fractionally engaged and supported by the rod support in an orientation parallel to a longitudinal axis of the housing. Each of the rods is independently axially movable from a starting position to an impression position. Movement of the rods from the starting position to the impression position is effected by bringing the rods into contact with an object with sufficient force to overcome the frictional engagement with the rod support. The rods are returnable to the starting position in preparation for subsequent use.

Title: Gear grinding machine
Inventor: KATSUMA TOSHIFUMI
IPC: B24B53/085
Filed: 2005-06-28
Granted: 2008-04-29
Abstract: To correct the tooth profile error of a ground gear, the wheel angle of a threaded grinding wheel is modified by dressing the threaded grinding wheel by a dressing device. To correct the helix form deviation of a ground gear, namely, to modify the helix angle of the gear, synchronization between the moving motion in the Z-direction of the threaded grinding wheel and the rotary motion of a table for installation of the gear is adjusted. When the helix form deviation is corrected by adjustment of the synchronization, a tooth profile change inevitably occurs. In consideration of the tooth profile change, correction of the tooth profile error by dressing is made.

Title: Range-finding system for a portable image reader
Inventor: PAGE HARRY
IPC: G01S7/64
Filed: 2005-11-01
Granted: 2011-01-04
Abstract: A range-finding system for a portable image reader is described. The range-finding system uses a distance-measuring device, such as an ultrasonic transducer, to determine the distance between the reader and a target, such as a label containing a bar code. An operator receives a visual indication which will assist in positioning the image reader within the optimal reading range of the target. The visual indicator may include three LED's of different color or with different blinking rates which will indicate to the operator that the reader is short, long or in the optimal reading range of the reader. In one embodiment, the reader would automatically cycle through an image acquisition or decode sequence when range finder detects that the target is within the optimal reading range of the reader. In another embodiment, the visual indicator will prompt the operator to manually trigger the image acquisition or decode sequence once the reader is positioned within the optimal reading range.

Abstract: The invention relates to a mobile communicating object (A) belonging to a communications network and comprising processing means (PM). According to the invention, when a communication has been established with another communicating object (S) belonging to the network, the aforementioned processing means generate a repeater (Fi) at each site (Hi) through which they pass. Moreover, when the repeater is generated, the processing means associate a timing counter (CTF) therewith and configure said repeater such that: (i) it can store an identifier that is representative of the location of the next repeater (F(i+1)) or site (H(i+l)) in the chain of repeaters to which it belongs; and (ii) at the end of a selected duration of time, it transmits the location identifier of the next repeater (F(i+1)) or site (S(i+l)) to at least one location server (SL) in the network, so that it stores said identifier together with the primary identifier of the mobile object (A). Preferably, once a repeater has addressed the location identifier, the relay activity thereof is terminated and, if the repeater does not belong to another chain, it is removed so that it no longer consumes resources.
