Title: Double rotary drilling apparatus for making directionally accurate bores, in particular horizontal bores
IPC: E21B4/20
Filed: 1988-11-25
Granted: 1990-01-18
Abstract: This double rotary drilling apparatus with an inner pipe string and an outer pipe string as well as separate rotary drives for both strings is equipped with a directional drilling machine.

Patent DE-4221266-C1 (DE)
Inventor: SIZOV ANATOLY PROF
IPC: F27D3/16
Filed: 1992-06-26
Granted: 1993-10-21
Abstract: The invention relates to a process and device for blowing oxygen over a metal melt under a vacuum. The oxygen is to be applied over a large surface with a large intermediate phase area while avoiding overcooling in the metal bath by simple, easily maintained structural means. To this end the flow of oxygen in the lance is accelerated and compressed in pulses. The plug-shaped oxygen pulses leaving the lance in succession extend in a bell shape in the vacuum above the melt, with the cores of the oxygen bubbles moving at a similar speed to the casings. At the base of the wall (41) of the blowing lance (40) there is an annular nozzle (42). At a distance behind the annular nozzle (42) in the direction of flow of the oxygen there is a blind tube (44) forming a fan-shaped compartment (43). Between the bottom (46) of the blind tube (44) and the head of the blowing lance (40) there is a pre-nozzle chamber (48) and in the head of the blowing lance (40) there is at least one nozzle (50) directed towards the melt, whereby the nozzle (50) takes the form of a Laval nozzle and has components (51) to stabilise the flow of oxygen.

Title: Sound damping for air supply duct for pneumatic brake servo
Inventor: BRUEMMER MICHAEL DIPL ING
IPC: G10K11/178
Filed: 1994-08-30
Granted: 1995-09-14
Abstract: The air speed through the duct is sub-sonic. Upstream of the sound source (5) and baffle (3) restricts the ir flow through a number of shaped jets (4) with the air speed inside the jets super sonic with the shaping of the jets designed to minimise sound generation. A plastic moulded baffle with Laval jets provides a simple fitting into the non porous gas duct. The jet profile tapers from an inlet aperture (7) to a minimum aperture (8) from where a second slope ducts the gas into a diverging pattern to aide outlet aperture (9). The inlet aperture is 1.01 to 2.5 times the area of the minimum aperture while th outlet aperture is 1.05 to 4 times the area of the minimum aperture. The jet profile is progressive and the jet length is 4 to 12 times the diameter of the minimum aperture.
