Title: Blast furnace tuyere - with improved coolant flow channels to avoid hot spots
Inventor: JUPKO LEW DMITRIEWITSCH
IPC: C21B7/16
Filed: 1974-04-02
Abstract: Blast furnace tuyere comprises a closed hollow annular housing; an annular partition dividing the housing into a head portion and a tail portion; a coolant inlet opening and outlet opening; and a coolant supply pipe fitting through the inlet opening at the end of the housing tail portion. The supply pipe supplies coolant into the housing head portion from where it passes through the outlet opening in the transverse annular partition. A longitudinal partition is mounted in the housing head portion to divide the inlet opening in the transverse partition into 2 parts for coolant entering the housing head portion, forming 2 coolant streams which simultaneously pass over the 2 halves of the housing head portion, the streams subsequently joining at the outlet opening in the transverse partition. The parts of the tuyere are cooled according to the extent of heat to which they are subjected so as to prevent dangerous overheating of the tuyere parts subjected to the most severe temp. effects.

Title: Electronic touch sensitive switch for lighting control - incorporates field effect transistor in parallel with light emitting diode
Inventor: POHL JOACHIM
IPC: H02M5/257
Filed: 1974-04-13
Abstract: The application is to switching circuits for contactless control of lighting or similar installations. The circuit is arranged so that an alternating current path is closed via an operator when the latter touches either of the contact plates. This current causes a voltage drop in series resistors and an appropriate value is picked off, rectified, and fed via limiting resistors, and a voltage regulating neon lamp, to the gate of an N-channel junction FET and also to a capacitor. The drain-source circuit of this transistor is in parallel with a light emitting diode controlling the resistance of a photosensitive resistor which in turn governs the switching point of the lamp controller. The bias on the FET gate thus governs the firing point of the controller.

Title: Screwed pipe coupling for stainless steel pipes - forms coned end of pipe with hard steel insert
Inventor: SCHMITZ DIETER
IPC: F16L19/05
Filed: 1974-04-13
Abstract: The pipe connection has a threaded end to suit the coupling nut. The end face of the connection is provided with a groove for the O-ring. The pipe which is of austenitic stainless steel has the bore opened out to a conical shape by driving in the conical insert which has an end flange which is pressed against the O-ring to form a sealed joint. The insert is made of 16 to 18 percent chromium steel and is much harder than the pipe. The coupling nut exerts pressure on the outer conical face of the pipe through the insert which prevents any scoring of the surface and ensures a leak-proof joint.

Title: Pressure cooker with rapid cool down and min of steam - has insulated pressure release chamber drawing off heat to cool inner steam
Inventor: MARLOTH HERBERT
IPC: A47J27/04
Filed: 1974-10-28
Abstract: The pressure cooker includes a steam condenser which can be connected to the inside by the pressure release valve (62) and itself is designed as a pressure release chamber (50) which is fitted onto one of the casing parts of the cooker, with insertion of a heat insulation layer (52). The pressure release chamber (50) is preferably provided with a spiral wall (74) or the like, which causes the steam flow to move in a vortex and has a high specific heat to draw sufficient heat from the steam in order to condense it. It is therefore important that the pressure cooking chamber is well insulated from the pressure release chamber (50) so that the latter is not heated during cooking. It is preferable for this same purpose if an electrical heating system (18) is incorporated in the base of the pressure cooker.

Title: Hydraulic piston cylinder actuator - has two types of pistons dividing cylinder into three chambers
Inventor: TERAMACHI HIROSHI
IPC: F15B15/06
Filed: 1974-12-02
Abstract: The actuator comprises a cylinder of non-circular cross section, two types of pistons and a piston rod which is provided with at least one spiral male thread having a pre-determined helical angle at a predetermined pitch. One of the pistons is mounted on the piston rod for rotation relative to it while being fixed against axial displacement along it and has two relief pressure control valves opening in respective opposite directions.

Title: Pressure bonding bodies made of metallic material - e.g. steel pipes for boilers, using super plastic phenomena
Inventor: OSHIDA YOSHIKI
IPC: B23K20/02
Filed: 1975-01-16
Abstract: In bonding bodies of metallic materials pressure is applied to the abutting surfaces to be bonded and simultaneously with the application of pressure the material near the bond is alternately heated and cooled to above and below the transformation temp (s). until a permanent bond is formed. The bodies are subjected to a triangular waveform temp. cycle and to a light mechanical load so that the pressure bonding is performed by making use of superplastic phenomena. In bonding steel pipes for use in boilers, e.g. where they may be exposed to sulphur atmos. and also in bonding cast iron, aluminium alloy etc. The light load may be applied without applying any external force for mechanical loading. The working time may be shortened to less than 5 mins. As the heating temp. is far lower than the m.pt. of e.g. steel there is no change in the metallurgical structure.

Title: Self locking furniture castor - with spring clamp around top of castor splayed apart under load
Inventor: REINHARDS GUENTER
IPC: B60B33/02
Filed: 1975-02-07
Abstract: The castor wheel (1) is located in a protective cowl (2) at the bottom of the castor fitting. The wheel axle (6) is fitted to the cowl with some vertical movement while a U-shaped spring clip (4) is fitted over the top of the wheel with its ends clipped over the ends of the axle.
