Title: Apparatus for measuring opaque bodies
IPC: G01B11/28
Filed: 1980-11-28
Abstract: Apparatus for measuring an opaque object including a frame, a transparent support in the frame for supporting an object to be measured, a light source and a transmitted light detection system on opposite sides of the support, the detection system including a measuring bridge containing a window defined by an overlapping area 2.1 of two slots in bodies which are relatively movable so that the window can linearly scan the body to be measured.

The outer tube may be rotated in synchronism with translation of the bridge relative to the object and may carry a pulse generator connected to a counter controlled by the output of the photosensor(s).
Patent ES-8303132-A1 (ES)
Title: A process for reducing the width of a flat metal product by rolling.
IPC: B21B1/04
Filed: 1981-02-27
Abstract: To reduce the width of slabs from a reheating furnace to the width required in a finishing rolling train, thereby making it possible to feed slabs of only one width, or only a few widths, into the reheating furnace, the invention proposes rolling the slab in a width-reducing roll train in which the slab is subjected to traction such that plastic deformation occurs between the roll sets. In particular the width-reducing roll train has only one set of thickness rolls and has one or more sets of width rolls, thereby minimizing the length of the roll train and consequently reducing the lengths at the ends of the slab which are not subjected to the traction.

Title: Fuel injection pumping apparatus
IPC: F26B13/08
Filed: 1983-12-06
Abstract: A fuel injection pumping apparatus of the rotary distributor type has a distributor member rotatable within an angularly adjustable sleeve carried in the body of the apparatus. The sleeve is coupled to an angularly adjustable cam ring having internal lobes operable to impart pumping movement to a plunger carried in a bore in the distributor member. The distributor member has a delivery passage connected to the bore for registration with outlets in turn to the sleeve. The distributor member also has a further and restricted passage which registers with the outlet which has just received fuel for the purpose of absorbing pressure waves which may be reflected back to the outlet from the associated injection nozzle. The fact that the sleeve and cam ring are connected to each other means that as timing variation is effected by moving the cam ring angularly the phasing between the outlets, the delivery passage and the further passage remains constant.
