Patent ES-406940-A1 (ES)
Title: Optical system for capsule inspection
IPC: G01N21/85
Filed: 1972-09-22
Abstract: Medicinal-capsule inspection apparatus. Successive capsules spun on their axis in an inspection position are illuminated by intense light originating at a single lamp filament and reflected onto the capsule from a mirror in the form of a narrow band cut from an ellipsoid and positioned so that the filament is adjacent to one focus and the capsule adjacent to the other focus. The mirror wraps around the capsule endwise and produces on the capsule, as seen by a side-viewing lens and two end-viewing lenses, a narrow well-defined and continuous glare line area which is unique in that it curves over the ends substantially to the axis. The lenses project images of the capsule in side and end elevation. Masks at the image planes block the glare light from acceptable capsules, but contain apertures in selected relation to the image glare light areas, which pass light specularly reflected from defects in selected observation areas on the spinning capsules. Such light acts on light sensors behind the apertures to generate electrical control signals which provide inspection output information.
Patent ES-407190-A1 (ES)
Title: Making cast steel railway wheels
IPC: C21D1/84
Filed: 1972-09-30
Abstract: In the cooling of a steel railway car wheel having relatively thick hub and tread portions and a relatively thin plate portion, it is important that undue stresses are not set up in the plate portion and, simultaneously, that the tread is hardened for good wear qualities while the hub is kept soft for easy machinability. These objectives are achieved by providing a conveyor having suspended thereover, at spaced intervals, non-metallic insulating disks having a diameter approximately equal to or slightly larger than the wheel hub diameter, moving the wheels in intermittent steps along the conveyor so that the wheels stop for a predetermined period of time directly under successive disks until the hubs have cooled from a temperature of about 1,700 DEG F. to below the critical transformation temperature which is about 1,200 DEG F., the other portions of the wheels having cooled at a faster rate.

Patent ES-427112-A1 (ES)
Title: Reprocessing of final acid from nitroglycerine production
IPC: C06B21/00
Filed: 1974-06-08
Abstract: A process for treating final acid obtained in forming a nitrate of a polyhydric alcohol, said final acid comprising a mixture of sulfuric acid, nitric acid, water and said nitrate, said process comprising mixing said final acid with an aromatic nitro compound, allowing said mixture to stratify whereby said nitrate is dissolved into said aromatic nitro compound as one layer and there is another substantially nitrate-free waste acid layer comprising sulfuric acid, nitric acid and water, and separating said layers. Preferably the nitrate is trinitroglycerine and the aromatic nitro compound is dinitrotoluene. The waste acid layer advantageously is partially used to form additional dinitrotoluene and is partially mixed with fresh final acid since its presence serves to stabilize such final acid by preventing any settling out of trinitroglycerine, presumably by the action of the small amount of dinitrotoluene which may be present in said waste acid.
