Title: Method of preparing photochromic glass
IPC: C03C4/06
Filed: 1980-07-25
Abstract: A process for producing a photochromic glass which will exhibit a brown colouration in its darkened state without a degradation in the photochromic properties of the glass taking place. The process includes the steps of forming a batch of specified components which include silver halide and tin or a tin compound and subjecting the resultant batch to a series of glass-forming steps so as to develop photochromic properties in a glass article formed from the molten batch. The invention also provides a photochromic glass having silver halide crystals and tin dispersed throughout the glass, the glass having in its darkened state a brown colouration which is described in accordance with the Hunter L,a,b, Colour Scale System by the rectangular region having corners defined by the (a,b,) co-ordinates: (5,1), (1,5), (12,16) and (16,12), the 1/2 OD FT of the glass being 120 seconds or less.

Title: System for generating coherent photon beams
IPC: H01S4/00
Filed: 1980-09-08
Abstract: This invention concerns generating a coherent x-ray, gamma ray, or other coherent beam of photons extending to wavelengths in the far infra-red, in which high energy photons are generated via recombination of electrons and highly charged atoms or electron-positron pairs 5, 6 which have been trapped within an intense laser beam 3 to translate the kinetic energy into oscillation energy. The generator is useful in non-linear optic and fusion studies, industrial material treatment, medical applications and initiation of chemical reactions. <IMAGE>

IPC: B07C5/344
Filed: 1981-07-30
Abstract: An automatic test equipment for disc shaped components in which the components A, B, C, to be tested are fed in succession in a channel 1 to a pre-test position 2. The presence of a component in the pre-test position is sensed by optical means 3 whereupon an insulated finger 5 is solenoid operated to move the component (A) from the pre-test position 2 to the test position, thus ejecting the previously tested component X. Whilst A is being tested the finger 5 is maintained in the forward position thus preventing B from entering the pre-test position. The component under test is held in good electrical contact against protruding contacts 8 in the base of the channel by a spring-loaded upper contact (not shown). <IMAGE>

Title: Inserting tabs into sheet stack at different positions
Inventor: THOMPSON JACK EVANS
IPC: B65H33/04
Filed: 1981-11-12
Abstract: Successive batches of sheets individually being stacked on a descending platform are identified by laterally spaced tabs inserted into the growing stack. The tab inserter (26) is incrementally moved parallel to one side of the growing stack following each tab insertion by a lead-screw (14) intermittently driven by a motor through a clutch-brake device (21) under the control of a series of cams (47) on a cam-shaft (24) driven by the motor, see Figure 1. The tab inserter is pivoted by cam (40) about the axis of the lead screw (14) to move the head (29) of the inserter towards and away from the stack during tab insertion. The tabs are cut from a strip (27) after the leading end is inserted into the stack. The inserter can be held in its outermost position away from cam (40) and the stack by a stop (43) so that the tabs then project by a greater amount from the stack and thus identify selected sheet batches. <IMAGE>

Title: Putting practice implement
Inventor: MIYAMAE TOSHIAKI
IPC: A63B69/36
Filed: 1982-02-24
Abstract: A putting practice implement comprises a plane board A having a first plurality of sensors 1,1', 2,2', 3,3', arranged as pairs along the median line X-Y of the board and a second plurality of sensors 4,4', 5,5', 6,6' arranged as pairs about the said median line, the sensors of each pair being closer to one another in the case of the second plurality than in the case of the first plurality. All of the sensors are connected via a computer 9 to a display 10. A putter P has a sole covered for the most part with a reflective material such as aluminium foil but having a central strip of a non- reflective material. As the putter P passes over the board A, light emitted from an element 7 on each sensor is reflected, or not, as the case may be, from the sole of the putter back to a light sensing element 8 on that sensor and thus deviations of the putter from a straight path directly above median line X-Y can be detected and indicated on the display 10. <IMAGE>
