In a photo-electric light meter a light transmitting cover for the surface of a barrier layer cell comprises a clear flat body of light transmitting material having parallel top and bottom surfaces, and provided with sets of parallel grooves intersecting each other at right angles on its bottom surface the surfaces of the grooves being light diffusing so that light incident normally on the cell surface is unaffected but that incident at oblique angles is diffused. As shown the light transmitting cover is composed of two sections, 10, 8 (Fig. 2), the lower section having a flange which is held under shoulder pieces 5 which define the light entering aperture of the meter. The lower part of the cover is held in contact with a filter 11 and the photo-electric cell by a spring plate 12 which forms one of the connections to the photo-electric cell. The grooved surface of the cover is shown in detail in Fig. 3 and comprises a number of V-sectioned grooves intersecting at right angles. The depth of the cuts is such that the apices of the " V's " project into the part 10 of the cover. The sides of the grooves are left unpolished after machining, thus producing the necessary light diffusing surface, and the sides of the block 10 are also unpolished. Dimensions are given in the Specification which also states that the total projected grooved area should be approximately one-half of the total effective area of the bottom.

Title: Improvements in or relating to electrical counting or distributing circuits
Inventor: BEESLEY JOHN HENRY
IPC: H03K23/82
Filed: 1954-10-28
Abstract: 775,134. Electronic counting apparatus. GENERAL ELECTRIC CO., Ltd. Oct. 13, 1955 [Oct. 28, 1954], No. 31227/54. Class 106 (1).  A counter having a small plurality of input leads comprises a ring of gas discharge trigger tubes arranged so that a striking voltage may be applied to a second tube when, during one counting cycle, the first tube of an adjacent pair is conducting and a predetermined voltage occurs on a particular input lead, and when, during the next counting cycle, the first tube is again conducting and a predetermined voltage occurs on a different one of the input leads. A pair of diode gates, such as 28, 29 and 35, 36, control the application of a rise in voltage at the cathode of a first tube (e.g. 3), when it becomes conductive, to the trigger electrode of a second (succeeding) tube (4) in the case of each of the tubes 3 to 7. One input to each gate is connected to one of the lines 1, 2 on which positive counting pulses appear alternately; the other inputs to the gates are connected to one of the lines 30 to 33 each of which is connected to one or more cathodes of a second ring of tubes 8 to 11. Thus, as will be seen from the table, the tubes 3 to 7 are rendered conductive in succession as the first five input pulses appear alternately on terminals 44 and 45. Moreover the conducting state in the ring of tubes 8 to 11  passes from 8 to 9 as a positive pulse passes through a line 37 when the tube 5 becomes conductive, and from 9 to 10 when a positive pulse passes through a line 38 when the tube 7 becomes conductive. As mentioned above, control voltages from the cathodes of the second group of tubes 8 to 11, acting via the lines 30 to 33, cause each firing of the tubes 3 to 7 during the second cycle to be controlled from a different input lead as during the first cycle. Specification 768,653 is referred to.
