Abstract: An apparatus for scanning a document is generally similar to that disclosed in Specification 1, 089, 536, but includes control means positioned between the scanning mirror and the image receiving surface for selectively varying the scanning speed to vary the size of the image produced thereon. Mirror 23 is oscillated by a sector 220 connected by drive tapes 251, 252 to a sector 104. The sector 104 is secured to a shaft 101 oscillated by a cam 134 through a cam follower 142. The length of the scanning arc and scanning speed are controlled by the tape 251 or 252 which is selectively operable by a pneumatic cylinder 210 or a solenoid (not shown) having a plunger 211 which actuates a lever 230 between adjustable stops 255, 256. When the plunger 211 is in the lower position, the drive tape 252 is operable to drive the sector 220 at a higher speed and through a greater arc than when the tape 251 is operative. A lens 24 is adjusted in the manner described in Specification 1, 223,427. to vary the magnification in the X direction. Reference has been directed by the Comptroller to Specification 1, 089, 536.

Title: Polyester
IPC: C08G64/40
Filed: 1969-08-26
Abstract: Finely divided microcrystalline polyesters (e.g. polyethylene terephthalate or bisphenol A polycarbonate) capable of forming a stable colloidal dispersion are obtained by hydrolysing the polyester in a liquid medium having a mild swelling action on the polyester (e.g. ethylacetate, ethylene glycol or water) and then mechanically disintegrating the hydrolysed polyester. The hydrolysing agent is preferably a base, such as sodium hydroxide, urea, ethylene diamine or n.propylamine. Prior to hydrolysis the crystallinity of the polyester may be increased by heating it under nitrogen or in dimethyl silicone. The polyester may be mixed with miorocrystalline starch, cellulose or nylon for use in the production of moulding powders.

Patent ES-401991-A1 (ES)
Title: Balanced pressure fuel valve
IPC: F01L9/10
Filed: 1972-04-21
Abstract: A hydraulic fuel valve assembly which equalizes the pressure of fluid at the hydraulic cylinder during the closed-valve condition with the pressure of fuel at the nozzle region, to thereby assure that the hydraulic cylinder is always full and to minimize variations in the force that must be applied by the hydraulic piston when fuel pressure varies. The valve assembly includes a passageway connecting the fuel supply line to the nozzle region of the valve, and a channel leading to the hydraulic cylinder to supply pressurized fuel to it. A check valve is located along the channel to prevent the flow of fluid out of the hydraulic cylinder when it is highly pressurized during valve opening. In a valve wherein a fluid other than fuel is employed in the hydraulic cylinder, a bellows or sealed piston is installed in the channel between the check valve and the fuel line to prevent mixing of the hydraulic fluid and the fuel. The valve assembly includes a valve body that forms the hydraulic cylinder, and a separate valve insert that contains a valve plunger and an insert housing that defines the valve seat and that limits plunger movement away from the seat, to thereby enable testing and adjustment prior to complete valve assembly. nBACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to valves and, more particularly, to hydraulically actuated valves.

Title: Control device for telephone exchanges - redirected connection is partially released up to certain switching stage
IPC: H04Q3/00
Filed: 1975-11-21
Abstract: The switching connection control device is designed for telephone exchanges having selectors with latching characteristics. When required, a redirected connection is partly released up to a certain switching stage which cannot again be used, and a new connection is built-up onwards from this stage only. In order to build-up a connection to a third or a further subscriber, an additional latching selector is deliberately operated in a switching stage. Its input is connected to the existing connection between two subscribers while its output is connected to the third or further subscribers. The usual testing, preventing unwanted double connections, is suppressed when the aforementioned selector is operated.

Title: Apparatus for texturizing yarn
IPC: D02G1/12
Filed: 1975-11-26
Abstract: A tow of continuous filaments is fed by aspiration into a stream of compressible fluid.

Patent ES-475788-A1 (ES)
Title: Process of imparting a permanent curvature to a sheet of glass
IPC: C03B23/03
Filed: 1978-12-07
Abstract: An untempered sheet of glass is given a predetermined curvature by means of pre-heated forming dies (3,4 in FIG. 1). The glass sheet (1) is not pre-heated or is heated only to a relatively low temperature prior to being inserted between the dies. Heat transfer from the dies to the glass prior to closure of the dies produces or assists in producing in the thickness of the glass sheet a transitory thermal stress gradient which gives resistance to breakage under bending forces. The absence of high temperature pre-heating of the sheet is conducive to a more predictable stress distribution pattern over the area of the sheet prior to bending. The process enables predetermined sheet curvatures to be achieved with higher degrees of accuracy.
