Abstract: 1289538 Film transport mechanism AGFA GEVAERT AG 29 Sept 1969 [28 Sept 1968] 47797/69 Heading G2A A roll film camera has a feeler movable from an inoperative position to an operative position in which it engages a metering perforation in the film at the same time as it locks the film transport mechanism, and has further means which, when the camera release is operated, disengages the feeler from the perforation and holds it thus long enough to prevent it re-entering the same perforation. As shown, the feeler 8b is formed on a lever 8 which has a spring arm 8a bearing against a fixed stop 10. The lever is thus urged in a clockwise direction, so that feeler 8b bears against the film 4 and will engage in a perforation 4a, as in Fig.2. As it does so, an arm 8c oflever 8 engages a ratchet wheel 6 secured to the take-up spool 5, so blocking further film transport. When the release 7 is operated, an oblique surface 7a thereof engages a further arm 8d of lever 8 and pivots it counter-clockwise against spring arm 8a, thus disengaging feeler 8b from the film perforation and arm 8c from the ratchet wheel 6, so that further film transport can now be made, Fig.1 (not shown). A further lever 11 is freely pivoted on lever 8, and has a downwardly extending arm 11a slightly longer than feeler 8b, Lever 11 has a straight edge 11b which, when the mechanism is in the position of Fig.1 (not shown) locates against a fixed member 12b, so holding it with arm 11a downwards. Thus when the release 7 is liberated feeler 8b cannot re-enter the same perforation 4a, because arm 11a is resting against the film. When the film is wound on, arm 11a drops into the perforation 4a, and is carried along by it, until it is rotated out of the perforation by the engagement of straight edge 11b with an inclined part 12a of member 11b. Feeler 8b is now free to engage in the next perforation as soon as it comes into register. Fig. 3 (not shown) is a modification with an alternative means of performing the function of lever 11.

Abstract: 1289838 Selective signalling TELEDYNE Inc 15 Dec 1969 [19 Dec 1968] 40680/71 Divided out of 1289837 Heading G4H The subject-matter of the Specification is included in the Specification 1,289,837 (see Division H1) but the claims relate to an electro-optical encoding and decoding apparatus in which electrical test data obtained from semi-conductor devices situated in a common wafer 10, Fig. 2, are translated into a coded pattern of light by an array of lamps 60 and the pattern is projected on to a photographic film 22 for recording, the position of each individual pattern on the film corresponding to the position within the wafer 10 of the device to which the pattern relates. A lamp 52 projects an image of a reference grid 54 on to the film simultaneously with the projection of the coded test data pattern. The projection arrangement includes convergent light guides 58 adjacent the lamps 60 and a beam splitter 46 immediately above the film 22, and is mechanically connected to an XY indexing table 12 carrying the wafer 10 in order to synchronize indexing of the wafer 10 and film 22. In order to read-out the data the film 22 and wafer 10 are clamped side-by-side in a frame 26, Fig. 4, which is placed on an XY indexing table. The film 22 is positioned below an optical read-out head 36, light from a lamp 96 being projected into the head 36 through each coded pattern in turn. The wafer is situated beneath a pick-up head (not shown) which picks up individual devices from the wafer, now broken into separate dice retained in their original relative orientations, and transfers them to respective delivery stations on the basis of the read-out test data. Fig. 7 illustrates an example of a coded pattern recorded on the film 22 and corresponding to the test data from a single device. The pattern includes nine areas arranged in three rows 124, 126, 128, the areas being either clear or opaque depending upon the device test data. The detection system in the read-out head 36 includes two banks of three photo-diodes, information being contained in the transitions between adjacent areas in each row 124-128 as the diodes are scanned across the pattern. Transitions from clear to opaque or vice versa represent a logical 1 while no transition between adjacent areas represents a logical 0. Two of the areas in row 126 are always opaque as shown for machine control purposes, leaving seven channels for the test data. The lower area of the pattern is a "parking area" in which the reading scanner rests between indexes, and which may include, in the last pattern of each line, an opaque portion which causes the direction of indexing of the XY table to be reversed.

Abstract: 1324431 Welding by pressure CLARKE CHAPMAN-JOHN THOMPSON Ltd 19 April 1971 [31 Jan 1970] 4754/70 Heading B3R In a method of friction welding in which the workpieces partake, while in rubbing contact, of relative translatory movement along an orbital path to generate heat for welding and are then brought into axial alignment for welding, the relative movement is generated by combining two similar eccentric rotational motions performed in the same rotational sense about respective axes and the workpieces are brought into alignment by altering the phase of one of the eccentric motions relative to the other to reduce the combined eccentricity to zero. Apparatus, for carrying out the method comprises an outer rotary member A adapted to be driven about the welding axis 3, an inner rotary member B eccentrically and rotatably mounted in the member A and adapted to be driven at the same speed as the member A, and a work-holder C eccentrically mounted within the member B and rotatable relative thereto. Torque anchor means 30 prevents rotation of the work-holder C (other than to a limited extent) relative to the member B and ensures that in the welding position the workpiece W1 is held in perdetermined angular relation to the workpiece W2. The eccentricity e of member B relative to A is equal to the eccentricity of workholder C relative to the member B so that by relative angular adjustment of the members A, B the resultant eccentricity of the work-holder C can be varied from zero to a value 2e. Drive to the members A and B is transmitted from a motor 10 through an epicyclic gear device 7 having two sets 13, 15 and 14, 16 of stun and planet gears arranged respectively to transmit drive via output shafts 20, 21 to the members B and A. The planet gears 15 are supported from an annular carrier member 17 which is arranged to be given a limited angular movement (e.g. by operation of a piston and cylinder or a rack or screw means) the effect of which is to alter the phase or angular relation of the members A and B thereby providing means whereby the workpieces can be brought into alignment for welding without disconnection of the drive. Adjustable balance weights may be mounted on the members A and B to counter balance the workpiece and work-holder. It is envisaged that the orbital motion may be produced by applying an eccentric motion to each workpiece holder instead of combining both on one and keeping the other stationary; also the motions may be non-circular if desired. The method may be applied to the welding of workpieces of non-circular cross-section.
