Abstract: 1,063,060. Photo-electric measuring apparatus. J. HEIDENHAIN, [trading as WENCZLER & HEIDENHAIN] Aug. 5, 1964 [Aug. 5, 1963], No.31879/64. Heading G1A. Photo-electric apparatus for position determination comprises a scale consisting of an optical diffraction grating having a grating constant a, a lined plate 2 movable in accordance with the member whose position is to be determined along   a line spaced ka<SP>2</SP>/# from the grating where k is a whole number and # is the spectral centre of gravity of the sensitivity of the whole photoelectric apparatus viewing the combination. In Fig. 1 a lamp 3 provides light collimated by lens 4 and directed through the grating 1 whose rulings are metal coatings on a glass carrier to the movable plate 2 which carries similar rulings. Light passing the plate 2 is directed by lens 5 on to photo-diode 8. The grating constant of the elements 1 and 2 is 10 Ám. as shown so that if the centre of gravity of the spectral sensitivity of the system from source up to and including the detector is 1À1 Ám. the elements may be separated by 90 Ám. or a multiple thereof. Best results are obtained when k is small e.g. 1. To modify the shape of the electrical signal/position curve the ratio of the absorbing and transparent zones in the gratings may be modified. As shown with a 3 Ám. /7 Ám. ratio for the scale and 5 Ám. /5 Ám. for the plate a sine squared curve is produced. The ratio of maximum to minimum values in the electrical output is not significantly reduced by this modification.

Title: Improvements in glassware machinery
IPC: C03B9/16
Filed: 1924-10-21
Abstract: 250,299. Hall, R. F. Oct. 21, 1924. Blowing.-Relates to a bottle-making machine of the turnover type in which a number of sets of parison and finishing moulds are carried by a table that rotates, preferably continuously, about a stationary central column. Each mould-carrying unit comprises a casting p, Fig. 1, which is secured to the rotary table c and has its lower part formed as a trunnion s on which the arms t of the finishing-mould are journaled. The casting is formed with a horizontal boring within which a sleeve u is mounted so that it is free to rotate but cannot move longitudinally. A toothed wheel v secured to the sleeve engages an interrupted circular rack w secured to the stationary central column a, so that the sleeve is periodically rotated as the table c rotates. A second sleeve 3 is mounted within the sleeve u and is constrained to rotate with it, but it is free to move longitudinally. This sleeve carries the halves 7 of the parison mould which are opened and closed by a roller 12 and a cam fixed to the central column a. The sleeve 3 also carries an arm 14 provided with a cover 16 which closes the bottom of the parison mould at appropriate times. The blowing-head 22 is carried by an extension 21 of the sleeve u, and the halves 23 of the ring mould are pivoted on the extension 21. The blowhead is connected by a passageway 34 in the casting p and by pipes 42 with a distributing-ring 43 by which suction or compressed air is applied to the blowhead. The passage 34 is closed by a spring-loaded valve 36, and both this valve and the mandrel for making the initial opening in the blank are operated, as the mould 7 is turned over, by cams secured to the casting p. The halves 61, Fig. 5, of the finishing mould are pivoted in the arms t, and they carry pinions 62 which gear with racks 63 mounted on the table c. Thus as the mould is opened the halves rotate on their pivots in order to give clearance for the parison mould. In operation, a charge of glass falls into the parison mould and suction is applied to the blowhead to settle the glass into the ring mould. The cover 16 is then applied to the mould, and the rotation of the sleeve u turns the mould over, and the parison is blown up during the rotation. The parison mould halves are opened and are then drawn back towards the central column, this movement, which gives clearance for the finishing mould, being accomplished by the movement of the sleeve 3 longitudinally within the sleeve u. A mould bottom 65 is brought up against the parison, the finishing mould is closed, and the blowing-operation is completed. The bottle is finally discharged on to a belt conveyer which is travelling at the same linear speed as the bottle. The bottom 65 may be made movable in its support 70 in order that bottles with "pushed" bottoms may be made. The neck mandrel may be arranged to form the necks of the bottle with internal screws.
