Patent ES-412113-A1 (ES)
Title: Disengageable anti-backup device for film cartridge
IPC: B65H18/10
Filed: 1973-02-27
Abstract: An anti-backup device located within a film cartridge insertable into a camera permits the rotation of a film take-up core in a forward direction while securing the core against rotation in a reverse direction so as to prevent "clockspringing" of film when the cartridge is not within a motion picture camera. The anti-backup device comprises a fork-like member located within a hollow core on a rotatable film take-up core. The control member has flexible outwardly extending arms projecting from a body portion. In an engaged position of the control member, the arms thereof slide over internal cam or ratchet surfaces of the take-up core during rotation of the core in the forward (take-up) direction and hence permits such rotation. On the other hand, these arms engage the cam or ratchet surfaces of the core post to block rotation of the core when an attempt is made to rotate the core in the reverse (unwinding) direction. When the film cartridge is placed within a camera, the member can be moved axially until it is out of engagement with the cam or ratchet surfaces, thereby permitting free rotation of the core in both the forward and reverse direction. This eliminates the "clicking" noise associated with operation of the anti-backup device and also permits filming of fade-and-lap dissolve sequences in cameras having mechanisms for filming such sequences.

Title: Process for separating normal paraffins
IPC: C10G25/03
Filed: 1976-11-12
Abstract: An improved process for separating normal paraffins from a feed stream containing a mixture of normal paraffins and isoparaffins. The general process comprises the steps of contacting the feed stream with an adsorbent comprising a crystalline aluminosilicate thereby adsorbing normal paraffins and subsequently contacting the adsorbent with a desorbent material to remove the adsorbed normal paraffins. The improvement resides in a method of fractionating and recycling a desorbent material for re-use in the process in a manner that reduces total fractionation energy requirements. The method is particularly suitable when two desorbent materials are used in the process.

Patent ES-457980-A1 (ES)
Title: Encapsulated motor compressor for refrigerators
IPC: F04B39/12
Filed: 1977-04-20
Abstract: The invention relates to an encapsulated motor compressor assembly for refrigerators. An integrated motor compressor unit is resiliently supported inside the casing of the assembly on helical springs which engage the lower side of the stator laminations. The points of spring engagement are in a lower plane in which it is desired to prevent or minimize radial deflection of the motor compressor unit. This is accomplished by placing certain constraints on the design of the vertical motor shaft which has the usual eccentric crank for driving the compressor piston and a compensating weight for balancing the centrifugal effects of the crank. It was discovered that certain relationships between (1) the mass of the compensating weight and the spacing of its center of gravity from the shaft axis, and (2) the mass of the eccentric crank and the spacing of its center of gravity from the shaft axis, are in fact effective to minimize radial deflection of the motor compressor unit in the above referred to lower plane.
Patent ES-460281-A1 (ES)
Title: Elongatable telescoping support
IPC: B60S9/04
Filed: 1977-06-30
Abstract: An elongatable telescoping support, e.g. for use as a vehicle jack, comprises an outer prismatic tubular support and an inner prismatic tubular support telescopingly received in the outer support. A head is formed at the mouth of the outer support bar and has a guide surface inclined toward the outer support bar upon which a guide roller is shiftable. The guide roller is formed with a profiled portion adapted to grip a running surface of the inner support bar upon rotation of the guide roller to displace the inner bar out of the outer bar. According to the invention, rings at the end of the roller are received in the inclined windows which are formed in opposite walls of the prismatic head and a guide element is pivoted on this head and is urged, e.g. by a spring, in a direction tending to bias the roller inwardly and toward the outer support or bar. The guide element can be formed of a double-arm lever which can be actuated against the force of the spring to release the contoured portion of the roller from the running surface of the inner support bar and lift the roller along the surfaces of the guide slots to permit inward telescoping of the inner support member.

Patent ES-8103477-A1 (ES)
Title: Accelerated particle lithographic processing.
IPC: G03F7/038
Filed: 1980-05-27
Abstract: Ion beam lithography of particular interest in the fabrication of large-scale integrated circuits of unexpectedly increased throughput results from appropriate choice of (a) resist material and (b) ion species. Resist material, generally negative acting, is characterized by electron beam sensitivity inadequate for ordinary commercial electron beam lithography. The relevant characteristic responsible for inadequate electron beam sensitivity is the very characteristic responsible for enhanced ion sensitivity. Ion species, always of atomic number greater than that of proton, are dictated by the observation that sensitivity unexpectedly increases at a greater rate than predictable on traditional bases.
