Title: An improved method of formation of filament directly from molten material
IPC: D01F9/08
Filed: 1973-12-18
Abstract: A method of making filamentary solid material by contacting the surface of a pool of molten material with a circumferential projection comprising a portion of a rotating heat-extracting member is improved if the point of entrance of the projection into the molten surface is protected by surrounding the entrance point with a nonoxidizing gas.

Title: Method of an apparatus for filling a fuel injection pump
IPC: F02M59/34
Filed: 1974-09-13
Abstract: Method of and apparatus for filling a piston fuel injection pump of internal combustion engines with fuel. The fuel is fed through a side filling channel into a space over the piston which is under negative gauge pressure during the movement of said piston to its lower dead center, as well as during its movement toward its upper dead center until the filling channel is covered by the edge of the piston at the moment when there is still negative gauge pressure in the area above the piston. During the subsequent displacement of the piston to the upper dead center, the negative pressure in said space disappears and the fuel starts being discharged into the delivery conduit. The volume of fuel flowing through the filling channel is adjustable by varying the entering pressure of the fuel.

Patent ES-460200-A1 (ES)
Title: Method of and apparatus for converting molten metals into solidified products
IPC: B22D11/06
Filed: 1977-06-28
Abstract: From a casting apparatus, a metal melt flows to a cooled rotating drum (9) and solidifies to give a thin metal strip (10) which is stripped off and divided in a flying shear (12) into sections which are laid one upon the other on a table (20) by means of supports (14). After each section is laid down, the workpiece to be produced is moved backwards and forwards and pressed between a pair (22, 23) of rollers, whereupon the finished workpiece is pushed off the table (20) at the side. This makes it possible to produce in any thickness workpieces which were hitherto produced by laying one upon the other individual strips produced in separate casting apparatuses, and a considerable reduction in the costs and space requirement is thereby achieved.

Patent ES-471844-A1 (ES)
Title: Golf game simulating apparatus
IPC: G01S5/16
Filed: 1978-07-18
Abstract: Apparatus for simulating the playing of golf includes a tee area from which a player may drive a golf ball toward a curved target screen in front of the tee area. Three arrays of optical sensing devices are positioned to gather data as to the time and horizontal location at which a driven ball passes through each of three corresponding planes spaced apart between the tee area and the screen, and the horizontal location at which the ball rebounds from the screen through the plane closest to the screen. The sensing devices detect the passage of balls through the planes by detecting the reflection of infrared light from the balls. The infrared light is produced by an infrared light source and directed through the space through which the balls travel. A first and second ones of the planes are vertically disposed between the tee area and the screen and a third plane is disposed to extend from near the top of the second plane to near the bottom of the screen. With the data from the sensing devices, computer apparatus produces an estimate for display of the distance of travel and ultimate resting position the driven ball would have if allowed free flight. Use of sensing devices for detecting passage of a driven ball through three different planes and for detecting the rebound angle of the ball from the screen enables determination of the amount of hook or slice a driven ball would have. A television camera is positioned on one side of the tee area, and a grid pattern is positioned on the other side to provide a background and gauge against which movement of a player photographed for instant replay may be measured.

Title: Automatic gas cylinder shape checking system - utilises measurement of separation between two focussed light spots from beam aimed at cylinder profile
IPC: G01B11/02
Filed: 1982-09-10
Abstract: A cylinder is rotated, and whilst this occurs a profile of the cylinder is projected on to an optical detector. The difference between ttwo successive profile images is then determined, and this difference compared with a predetermined value. The cylinder is accepted for refilling only if the variation between successive profiles is less than the predetermined limit. A cylinder which is not within the limit is ejected from the conveyor. If light falling on the photosensors strikes more than one element at once, then the exact position of the beam is determined by a process of interpolation with reference to the intensity of light received by the neighbouring detectors.
