Title: Hot-blast stove lining - in short sections to reduce load on inner lining
Inventor: MUELLER LUDWIG
IPC: C21B9/06
Filed: 1972-07-24
Abstract: The inner lining of a hot-blast stove is built in sections which increase in size as one proceeds up the stack. Each section overlaps slightly the one above it, with a small gap in between, to allow relative movement. Each section is secured to an outer refractory section, which, because it is entirely protected from the hot gases, can be of a cheaper material which yet has the necessary strength. The whole is contained in a metal casing which is stepped as required to accommodate the steps in the refractory, and may be externally supported. The inner high-duty lining is therefore not subjected to the weight of the whole lining but only to the wt. of its own section. Taller stacks and higher temps can be obtd.

Title: Corner joints for sheet metal furniture - made by projection welding of bridging plate under joint
Inventor: SEEBER HORST
IPC: B21D53/74
Filed: 1974-04-18
Abstract: The sheet metal furniture is made by turning over edges of flat plates to form stiffening edge flanges. These flanges are joined at internal corners by a bridging plate which is projection welded to flanges while sizing force is exerted on the furniture component. This joining method ensures that the mitred joint is not subjected to excessive heating on brazing or conventional welding which results in distortion on cooling. The mitred corner is made by bending a flat sheet metal plate to form corner. The inwards turned edge flanges are cut at the bend to form the mitred joint. The sloping edges of these flanges are brought in contact on bending. An L shaped bridging plate with pressed welding projections is brought into contact with the mitred joint and attached to both flanges by projection welding under pressure. The location and alignment of the bridging plate and the mitred joint under pressure is facilitated by low friction PTFE plates which cover the clamping jaws.
