Title: Combining LNG with fuel gas - by injecting LNG into heated gas in bypass circuit
IPC: F17C9/02
Filed: 1973-10-12
Abstract: Liquefied cryogenic gas is added to a fuel gas stream to meet peak demand by passing a portion of the gas stream from the gas main through a branch circuit including a compressor and a heater which ensures vaporization and superheating of liquefied gas injected into the circuit rejoins the gas main. The heater is controlled in response to the temp. of the mixture of fuel gas and vaporized cryogenic gas in the branh circuit. The technique involves no consequent pressure drop in the gas main.

Title: Double-seated valve with leakage indication - has axial cleaning-fluid injection pipe leading to chamber between valve plates
IPC: F16K25/02
Filed: 1974-04-10
Abstract: The valve has a seating (4) and two valve plates (5, 6).

Title: Hydraulic clamping jaw mechanism - has compressed air operating piston to slide one jaw over other
IPC: B23Q3/08
Filed: 1974-11-26
Abstract: The device is for securing workpieces for mass-production machining between two jaws (1, 2) moving directly towards and away from each other. Under the force of compressed air or gas a piston in one of the jaws moves in the release direction and compresses a hydraulic fluid, which in turn causes a face on the other jaw to move in the clamping direction and secure the work. As the two jaws (1, 2) move towards each other, the piston (8) slides through a cylindrical bore inside the first jaw. The piston is fixed to a plunger (14) and compresses the hydraulic fluid (H). The fluid pressure is applied to the base of a cylinder (15) fixed to the second jaw, and sliding over the cylinder containing the piston and plunger.

Title: Spatial framework of cold formed profiles - allows partial prefabrication in workshop and connection of secondary flanges on site
IPC: E04B1/19
Filed: 1975-09-24
Abstract: The primary flanges are divided into two specially shaped flange profiles (1), to allow the pre-fabrication of even framework girders with continuous flanges in the workshop.

Title: Spring operated friction disc brake - has pneumatically assisted brake load control to match shaft speed acting on ring piston
IPC: F16D55/02
Filed: 1976-03-11
Abstract: A friction brake ring (2), attached to a rotating shaft (21) is axially pressed against the friction elements (9) by the force of compression coil springs (15).
