Inventor: WALTER HANS-PHILIPP
IPC: E21B4/14
Filed: 1994-12-06
Abstract: In the bottom part, a pneumatic deep-hole hammer (10) has an outer tube (55), a control-housing shell (60) together with non-return valve (59), and a central tube (80) which has radial passages (81, 83) and on which a percussion piston (75) slides. The head of an axially displaceable drill bit (90) can be slipped onto the bottom end (84) of the central tube. A cylinder liner (70) guiding the piston (75) and the control-housing shell (60) are circumferentially welded to the outer tube (55) over an axial area (welding zone S, length l). Sitting above them is an adapter (40) which has top air passages (42), carries a blast ring (50) with nozzles (53) directed upwards, and is connected in a drive-transmitting manner to a sleeve (15) either directly or via a sliding piece (30) with guided shaft (20), which sleeve (15) sits under the connection cap (11). The bottom end (23) of the shaft (20) forms a control slide relative to the adapter top part (41), from which passages (42, 47) lead to a control-housing chamber (62) with passages (63). An annular chamber (68) follows below a tubular body (61) between outer tube (55) and cylinder liner (70). The free cross-section of the annular chamber (68) corresponds to the narrowest central bore (12, 22, 32, 42/47, 62, 82, 92) in the through components (11, 20, 30, 40, 61, 80, 87/90). Bores, passages and grooves (71, 72; 81, 83) in cylinder liner (70) and central tube (80) interact in a motion-controlling manner with recesses (76, 76') and bores (78, 78') of the piston (75). <IMAGE>

Abstract: Process and apparatus for making gas generant pellets or tablets made for example of sodium azide, molybdenum disulfide and sulfur wherein powdered ingredients thereof are slurried in water, subjected to wet grinding, spray dried to a powdered material which is molded into pellets or tablets which find use in vehicle crash bags or inflators. 
     The improved process involves (1) softening the water before its use in slurrying the powdered ingredients to remove undesirable Ca and Mg ions and/or (2) adding sodium sulfide and/or tri-sodium phosphate to the slurry to precipitate any remaining undesirable Ca, Mg, Pb, Fe, Mn and Cu ions as non-hazardous compounds. Each of these metal ions is reduced to no more than about 25 ppm or less.

Abstract: A cold start control apparatus for diesel engines (26) includes a cold start switch (12), engine temperature and speed sensors (28, 24) and a transistor (16) all connected to a programmable controller (14). The transistor (16) is connected in a series circuit with a cold start relay (22) and the series circuit is connected to the run/crank positions of an ignition switch (10). The relay (22) has a pair of contacts through which a battery voltage (+12B) may be applied to a cold start assist apparatus provided for the engine. The cold start assist apparatus may be a thermostart element (30) such as a glow plug ignitor, or a solenoid controlled ether injection system (32). A permanent memory in the controller (14) stores an indication of the type of cold start assist apparatus provided for the engine. The controller (14) senses for actuation of the cold start switch (12) and applies a signal to the transistor (16) thus turning it on if (1) the ignition key is in the run or crank position, (2) the engine is cold and (3) the cold start assist apparatus is a thermostart element (30). On the other hand if the cold start assist apparatus is an ether injection system (32), the controller (14) responds to actuation of the cold start switch (12) to apply a signal to the transistor (16) only if (1) the engine is cold, (2) the ignition switch is in the crank position and (3) the engine speed is at least as great as a predetermined speed. While the transistor (16) is on, voltage is applied to the cold start assist apparatus. The controller (14) generates one signal to turn the transistor (16) on for each sensed actuation of the cold start switch (12). The duration of the signal is determined by the stored indication of the type of cold start assist apparatus provided for the engine (26).

Abstract: A video coding apparatus for performing predictive coding of digital video input signals. The apparatus employs a resolution selection controller that selects picture resolution to be used in coding of a source picture of a current frame, according to coding information in a previous frame. Such coding information includes quantizer step size, amount of coded data, and buffer occupancy. Before being supplied to a coding unit, the source picture is sent to a resolution converter, where the source picture is converted to gain the resolution selected by said resolution selection controller. The coding unit then encodes the source picture with the selected picture resolution.

Abstract: The present invention relates to a transmitter for transmitting a plurality of digital signals through a plurality of channels, the channels having a predetermined total bitrate allocated to them, comprising a plurality of encoders one associated with each channel; a multiplexer for receiving the encoded digital signal and transmitting them as a stream of data and capable of adjusting the distribution of the bitrate allocation between the encoded signals; and processing means for providing an indication of a target quality and an actual quality for each channel and causing the multiplexer to repeatedly adjust the distribution of the bitrate allocation in response to differences between the indicated actual quality and the indicated target quality for each channel so as to tend to equalise the difference between the actual and target quality across some or all of the channels. 
     In principle, by grouping encoders together in what will be termed herein "statistical multiplex groups", and making real time decisions about the bitrate requirements for those encoders, bitrate can be allocated to maximise picture quality for the group. The theory is that for a variety of different picture sources in a statistical multiplex grouping, to achieve a target picture quality the bitrate requirements of each will vary with coding difficulty. Thus a channel within the statistical multiplex group that is experiencing little difficulty in encoding its picture can free bits to channels that are having greater difficulty. The effect is to smooth the picture quality and to subjectively improve it.

Abstract: A filter network is presented for a phase-locked loop (PLL) circuit having a voltage controlled oscillator (VCO) with a control input and a bias input. The filter network includes a conventional filter circuit that provides a "pole" and a "zero" to the transfer function of the PLL circuit. The conventional filter circuit is coupled between the control input of the VCO and ground. An additional filter circuit is also coupled to the control input of the VCO, and to a bias input of the VCO. This additional filter circuit provides at least one additional "zero" to the PLL transfer function to extend the frequency range of the PLL circuit without impairing circuit stability. A transconductance amplifier is preferably employed within the additional filter circuit to facilitate tailoring of the open loop gain of the filter/oscillator circuitry.
