Title: Supported transition metal catalyst and process for the polymerization and copolymerization of alpha-olefins
IPC: C08F4/68
Filed: 1967-02-18
Abstract: An olefin polymerization catalyst is obtained by treating an aminoplast having free methylol groups with a compound of a metal of Group IVA, VA or VIA of the Periodic Table, which compound reacts with the methylol groups so as to give a product in which metallic radicals are bound by at least one valency to methylol residues and have at least one valency not so bound. Suitable aminoplasts are urea-formaldehyde and melamine-formaldehyde condensates suitable metal compounds include the halides, alkoxy-halides and alkoxides, e.g. TiCl 4 , Ti(OEt) 3 Cl, VOCl 3 , VCl 5 , and VO(OBu) 3 . The catalyst is activated by means of a hydride, organometallic compound or elemental metal of Group I, II or III of the Periodic Table e.g. a trialkyl aluminium or an alkyl aluminium halide. The catalyst is suitable for polymerization and copolymerization of ethylene, propylene and butylene. In Examples a melamine-formaldehyde resin or urea-formaldehyde resin is treated with excess pure TiCl 4 or VQCl 3 -TiCl 4 mixture the products, activated with tri-isobutyl aluminium, are used to polymerize ethylene or propylene in hexane, or an ethylene-propylene mixture without solvent. A composition is prepared containing the elastomeric copolymer of ethylene-propylene of Example 3, 50 p.h.r. of HAF carbon black, 5 p.h.r. of dicumyl peroxide and 0À5 p.h.r. of sulphur, and is vulcanized.
Patent ES-337996-A1 (ES)
Title: Device for determining the internal friction of materials
IPC: G01M99/00
Filed: 1967-03-14
Abstract: The internal friction of a material (1, Fig. 1, not shown) is measured in terms of the energy required to maintain constant amplitude oscillations of a torsional oscillator which includes the material (1), and, for example a shaft (5) on a flexible support (15) and an armature having arms (6, 7, 8, 9) and weights (14) thereon the said energy being proportional to the instantaneous velocity of oscillation and being supplied to coils (10, 12) from an amplifier (23, Fig. 2, not shown) which has its input connected to pick-up coils (11, 13). The pick-up coils 11, 13 measure acceleration or velocity, and the amplifier (23) has its gain automatically adjusted (at 24) by the difference between measured amplitude of oscillation (29) as obtained by integrating the velocity signal or double integrating the acceleration signal, and a reference amplitude (30). The adjustment of the gain control knob (24) is transmitted to an angle measuring device (32) driving a recorder (33), this giving a measure of the energy input to oscillating system and hence of the internal friction of the material. The measuring coils (11, 13) and driving coils (10, 12) all move in respective airgaps in yokes (19, 20, 25, 26), each of which has a central limb carrying a D.C. exciting coil (21, 22, 27, 28). A counterbalance weight (18) is adjustable on a lever arm (16) supporting the oscillating assembly.

Title: Method and apparatus for Projecting Motion Pictures
IPC: G03B15/08
Filed: 1967-03-17
Abstract: First and second frames of a film strip are projected with their images in superposed relationship, the image due to the first frame being faded out from a maximum to zero, and the image due to the second simultaneously faded in from zero to the maximum, at which point the film is advanced by one frame such that the second and third frames occupy the original positions of the first and second frames respectively, the image due to the second frame being rapidly adjusted to a maximum and then faded out as for the first frame while the image due to the third frame is adjusted to zero and faded in. The fade effects may be achieved by means of polarizing filters thus (a) a rotating polarized disc (Figs. 1-2) in front of two crossed polarized filters, one for each frame, said filters being interchanged at the film advance, (b) a stationary polarized filter in front of a rotating disc with crossed polarized segment (Figs.4-5 and 8), the projected beams passing through two crossed polarized segments, and (c) two stationary crossed polarized filters in front of a rotating disc having crossed polarized segments. The lens system (Fig.3) may comprise two small lenses, one for each frame, and a large lens, the image focal plane of which coincides with the plane of the projection surface. The film advance may take place in less than 1/24th sec., and a projection rate of less than 10 frames per sec. is mentioned.

Patent ES-363443-A1 (ES)
Title: Automatic letter underscoring mechanism
IPC: B41J29/26
Filed: 1969-02-08
Abstract: A typewriter includes a key 65 which when depressed acts, on subsequent depression of a character key 41, to effect printing of the selected character without an associated letter space movement, followed by automatic printing of a predetermined character such as underscore and a subsequent letter space movement. The typewriter comprises a single element printing head 11 actuated on depression of a character key 41 by a mechanism (not shown) acted on by lugs 43a during leftward motion of an interposer 43 under the impulse of a filter shaft 51. The printing head 11 is advanced in the letter space direction by an excapement mechanism through a linkage 55, a lever 57 and a torque bar 59. On depression of the key 65, the key is latched in place by a slot 73 engaging a frame 71 owing to a spring 79, a pin 81 thereby acting to depress a bar 87 into a position such that a step 91 thereof is in the path of a blade 53 of the filter shaft 51. On depression of the character key 41, rotation of the filter shaft is initiated through a bail 45. The selected character is impressed, and simultaneously the bar 87 is driven leftward to rotate a ratchet-wheel 97 and coupled cam 109 so that a follower 113 is urged to the right and the escapement linkage is broken by displacement of the lever 57 away from engagement with the bar 59 by engagement of an end 125 of the cam follower 113 with a portion 127 of the lever 57. The rotation of the cam 109 also acts to draw a follower 129 downwardly, a portion 141 thereof depressing a underscore interposer 63. A second cycle of the filter shaft 51 is thereby initiated, causing impression of an underscore. Simultaneously, the bar 87 is again impelled to the left to rotate the ratchet-wheel 97 and cam 109 further. The follower 113 is thereby drawn to the left by a spring 121, to reconnect the lever 57 with the bar 59 and permit the operation of the letterspacing escapement mechanism. The follower 129 returns to its inoperative position with the underscore interposer 63. The key 65 remains latched in its operative position for continuous underscoring until manually released. A ball interlock 20 is provided to prevent actuation of a second key before a printing and underscoring cycle is completed.
