Patent FR-2316014-A1 (FR)
Title: Continuously cast slabs press forged on all four sides
IPC: B21J1/04
Filed: 1975-06-30
Abstract: Process for mfg. hot rolled metla strips of different widths from slabs with a constant cross-section which are supplied from a casting plant, and using a single pass through a planetary rolling mill which requires feeding with thin slabs of varying widt. Before being fed into teh planetary mill, teh slabs are repeatedly hot worked by pressure tools to reduce the slab thickness while the slab width is increased, reduced, or remains unaltered; the pressure tools can follow the forward feed of the slab and have a slow working stroke and a brief idling stroke. The pref. press uses pairs of tools working on all four sides of the slab and described in the claims. The invention permits a planetary mill to be located near a continuous casting machine and one mould to be used for producing sheet of various size, because the press reduces the slab thickness to that tolerated by the mill; mould changes are thus avoided.

Title: Optical safety apparatus - pulsed beam acts on photo-electric device giving controlled and amplified output
IPC: H04B10/524
Filed: 1975-07-03
Abstract: A protective system on a machine has a beam producing apparatus and a device to give an output signal in response to it. The impulse generator (0) works from the light emitter (D1) which lights a photo-electric device (D2) with impulsed beams. There is a discriminator (G1) at the photo-electric device output so that a signal is only produced when the photo-electric device is illuminated. There is also time delay (H) connected between the impulse generator and the discriminator. The impulse generator is a unijunction device connected by controlled rectifier (S) controlling the light emitter. There are monostables assisting in time delay and oscillating functions.

Title: Belt-casting machine suitable for aluminium alloys - and method for obtaining uniform appearance on finished rolled sheet
Inventor: ALTHOFF HEINZ JURGEN
IPC: H03K3/282
Filed: 1975-09-02
Abstract: Process for casting molten metal flowing from a vessel into the solidification cavity in a belt-casting machine uses two continuously rotating steel belts near to each other in the casting zone and forming the top and bottom of a rectangular mould. The height of the level of the bath fed to the mould is larger than the distance between the casting belts in the region of the peak of the belt-driving rolls. The bath of metal is pref. in contact with the ingot mould along an arc corresponding to an angle of 1-15 degrees, esp. 5-10 degrees, at least upstream of the upper driving roll. The melt can be fed into the mould via an open gutter or a closed jet. Used, e.g. for the casting of wide sheets of aluminium with a small thickness, where the "head" of molten metal prevents the occurrence of surface segregation, at least on one side of the sheet. Such segregation is undesirable because it leads to surface streaks after the cast sheet has been rolled and is pickled or anodised.

Title: Charging suspension to a vessel - using tube with coaxial nozzle carrying gas, maximising flexibility, minimising gas consumption
IPC: F23D1/00
Filed: 1976-04-26
Abstract: An appts. charges a thick material into a vessel, e.g. a combustion chamber, an incineration chamber, or one for drying or calcination. Such materials may be in the form of a pasty suspension. The viscosity may vary over a wide range and there may be foreign objects present which can cause blockages. The material is charged under press. by using a tube and a jet of gas directed against the jet of material leaving the tube. The appts. consists of a feed tube under press. the discharge end of which projects into the chamber and is surrounded coaxially by an annular convergent nozzle. The gas is fed to and expands through the nozzle so that it meets immediately the stream of material. The invention allows materials to be charged into a reactor over a wide range of viscosities, imparting great flexibility of use, reducing the consumption of dispersing gas to a mix.
