Title: Universal isolation member and non-electric detonator cap including the same
Inventor: THURESON GARY R
IPC: C06C7/00
Filed: 1995-10-13
Abstract: An isolation member (34) for use in a non-electric detonator cap (10) has an interior passageway (40) extending therethrough and defining a positioning region (44) and a discharge port (56). Positioning region (44) provides a series of interior shoulders (46, 48) and an entry shoulder (52) respectively sized to receive and seat therein signal transmission lines of different outside diameters, thereby longitudinally orienting and spacing the signal-emitting end (30a) from the receptor charge (14). The isolation member (34) is preferably made of a semi-conductive material to bleed off to the shell (12) any static electricity charges transmitted through the signal transmission line (shock tube 30) so as to prevent static discharge initiation of the receptor charge (14).

Title: Slide lock for retractable tape measure
Inventor: BLACKMAN WILLIAM C
IPC: G01B3/10
Filed: 1997-07-21
Abstract: A slide lock for a power return measuring tape including an elongated lock member having a resilient locking tongue extending longitudinally from a lower end of the lock member. Followers engage guide means in the housing for the measuring tape. The guide means includes a guiding surface formed by a ridge in each side wall against which the pins ride. The guiding surface defines a descending path to guide the tongue from a position above a measuring tape in the housing to a position in contact with the measuring tape. A lock surface is formed at a lower end of the guiding surface with a protrusion at a junction between the guiding surface and the lock surface. Movement of the pins over the protrusion to the lock surface forces the tongue in contact with the measuring blade and causes the tongue to bend to apply a clamping force to the measuring blade.

Abstract: In a clock timing recovery circuit for recovering the clock timing from a baseband signal obtained by detection of a received signal, clock timing is rapidly established by using a clock which has been phase-shifted from the desired clock timing to sample the baseband signal, and by obtaining the optimum phase from the sampled signal obtained as a result. A clock-timing recovery circuit according to this invention does not require oversampling and provides easy optimisation of circuit constants.

Patent CA-2233310-A1 (CA)
Inventor: KNOBLACH WALTER
IPC: G01M3/22
Filed: 1996-09-16
Abstract: The invention relates to a method and an apparatus for providing a given volume of a test substance (H2) in a monitoring line (2) which is filled with a test medium (e. g. air) and is provided along a section for determining concentration profiles. For the purpose of transporting a column of test medium through the monitoring line (2), the pressure (p) in the monitoring line (2) is increased by switching on a pressure pump or, for the same purpose - in an alternative embodiment - is reduced by switching on a suction pump (12). A given metering volume of the test substance (H2) is automatically released in the monitoring line (2) when a given limit for the pressure (p) is passed. The release of the given metering volume of the test substance (H2), after it has been carried along by the column of test medium, results in a test peak in a sensor (11) which responds to the test substance (H2) and is connected to the monitoring line (2).

Inventor: ROSEN HOWARD B
IPC: H04M1/656
Filed: 1998-04-22
Abstract: An audio storage and playback unit coupled to the telephone line is adapted to record a message off the telephone line in response to the application of a "record" control signal and to play back the recorded message onto the telephone line in response to the application of a "play" signal. A first tone decoder responds to the actuation of a first predetermined key on the telephone key pad by generating the "record" signal. A second tone decoder responds to the actuation of a second predetermined key by instituting the generation of the "play" signal. In a preferred embodiment, a third tone decoder responds to the actuation of a third predetermined key by instituting the generation of a "stop" signal. Thus, if a call is received which is for a party other than the person who answered the call, the caller may leave a voice message. The person who took the call pushes the first predetermined key to start recording the message and the third predetermined key to stop recording. Later, when the person for whom the call was intended is available, he/she may pick up a telephone and touch the second predetermined key to start playback of the message. When the message has been delivered, the user may touch the third predetermined key to end the playback process.
