Title: Method of and an apparatus for testing an optical component
IPC: G01M11/02
Filed: 1973-04-12
Abstract: 1428031 Testing optical components EALING BECK Ltd 14 March 1974 [12 April 1973] 17727/73 Heading G1A An optical component is tested by measuring with a photo-detector a particular transfer function in the presence of radiation from an extended source of predetermined brightness so arranged the glare from this source (e.g. due to scatter by the tested component) reaches the photo-detector; the detector signal is then normalized with respect to the total light flux to provide a Glare Reduced Transfer Function, GRTF. This function in effect combines the particular transfer function with a glare measurement. In Fig. 1 the particular function is the Modulation Transfer Function, MTF; the optical component tested is a lens 10, through which a pattern produced at slit 18 by source 15, scanner 16 and lens 17 is transmitted to photo-multiplier 28 in a basically known manner. Also provided is a diffuse surface 13 illuminated by sources 29; this surface acts as an extended source, from which radiation can only reach the photo-multiplier due to defects in lens 10, or to diffraction or scattering at the lens edges. This radiation causes a background illumination at the photo-multiplier, shown as g in Fig. 2. This figure shows that the maximum light flux at zero cyles/mm is Co + g, while the minimum is g; the GRTF which is given by A pinhole object and a grating analyzer may be used in place of the object generator slit 18 and analyzer slit 26 of Fig. 1 to produce a single frequency MTF measurement if desired.

Title: Improvements in or relating to electric regulating apparatus
Inventor: HENMAN CECIL BOURNE
IPC: G05F1/247
Filed: 1954-06-17
Abstract: 780,166. Transformer systems. BRENTFORD TRANSFORMERS, Ltd. June 13, 1955 [June 17, 1954], No. 17852/54. Class 38 (4). Series boost transformers 1-4, supplied from a common source 10, are associated with a single voltage regulator VR and individual switches SW1-SW4 to provide a system wherein continuous rotation of a common operating shaft for the switches from one extreme position to the other progressively changes the condition of the first transformer from one of maximum buck to one of maximum boost and then similarly changes the condition of the other transformers in sequence. The common operating shaft acts on each of the switches in sequence, through a Geneva drive, each switch effecting a complete cycle of operations before the next switch of the sequence is acted upon, which cycle comprises (1) interrupting the direct connection of the primary winding of the associated transformer to the source 10 and connecting the winding across the moving contacts of the voltage regulator whilst these are at the maximum voltage position; and (2) re-connecting the winding to the source 10, but with reversed connections, after the moving contacts of the voltage regulator have been moved to the other limit of their travel and the output of the transformer consequently first reduced to zero and then increased to maximum with phase reversal. The movement of the voltage regulator and of the common operating shaft of the switches is preferably effected by electric motors, there being electro-mechanical interlocks for ensuring that the switches can only move when the regulator is at the ends of its travel and an automatic control system for starting and reversing the drive motor of the regulator in dependence upon the movements of the switches SW1- SW4. Instead of a voltage regulator of the reversing type shown, a regulator having a single moving contact may be employed if the switching system is such as to allow the transformer connections to the regulator to be reversed. If phase reversal of the output voltage of the transformer is not necessary the switching system may be arranged to shortcircuit the primary winding when the regulator reaches zero voltage position.

The preferred polymer is a polyethyleneterephthalate based polyester, but polyolefines, polyurethanes, polyamides, and polymers of styrene, methacrylic acid and its esters are also specified. Preferably the temperature differential comprises keeping the centre of the web cooler than the edges, and when drawing longitudinally, the drawing force is locally varied across the web width, so as to be strongest at the centre.

Title: Maize harvesting machine
Inventor: TRAILESCU STANICA
IPC: A01F29/06
Filed: 1966-04-28
Abstract: A maize harvester, of the type which snaps off the ears and simultaneously chops up the stalks and ejects chopped stalks from the machine, comprises at least one pair of driven vertical ribbed rollers the mutual inclination of which is adjustable, and a chopping drum associated with the or each pair of rollers and located at such a position behind the rollers that the distance between the cutting point and the nip of the rollers is less than the length of the majority of the ear-carrying peduncles of the plants.  Tearing of the peduncles is thus avoided, and the ears will fall readily from the roller-nip.  The chopping drum comprises a series of helically-arranged blades formed into a reel with intermediate supporting plates perpendicular to the axis of rotation, these plates having radial fins which produce an airblast to discharge the chopped stalks into a delivery-duct.
