Title: Improvements in or relating to low reflection absorbers for absorbing or minimising reflection of radio waves
IPC: E04B1/92
Filed: 1955-10-06
Abstract: 797,610. Radio wave absorbers. WERNER GENEST GES FUR ISOLIERUNGEN. Oct. 6, 1955 [April 2, 1955], No. 28558/55. Addition to 776,158. Class 40 (7). Relates to a radio wave absorber of the type disclosed in the parent Specification comprising a plurality of parallel planar films of lossy material disposed at an angle to a base surface, the effective loss resistance of the films decreasing towards the base surface. According to the present invention the films are applied to a carrier which together with the base surface forms a rigid structure which may be located at any point in free space. In one embodiment, Figs. 3 and 4 (sectional views), and Figs. 1 and 2 (not shown), the lossy films are applied to the inner walls of two perpendicular series of equally-spaced parallel slots 6 cut in a block of weather-resistant material (dielectric constant and permeability preferably equal to unity) the bottom of each slot being serrated with the length of each serration equal to the spacing between adjacent slots. The block is mounted so that the waves 13 to be absorbed are incident normally on the uncut surface of the block and a conductive layer, e.g. metal foil or wire gauze, may be applied to the cut base surface 4 or spaced therefrom by an odd number of quarter wavelengths to form a resonator, Fig. 5 (not shown); two such structures may bo mounted back to back with a common conductive layer, Figs. 6 and 7 (not shown). A plurality of absorbers adapted to absorb waves of different wavelength may be arranged in superposition.

Title: Improvements in calculating apparatus
Inventor: SENTER FRANK GERRISH
Filed: 1932-10-13
Abstract: 395,210. Calculating-apparatus. SENTER, F. G., 44, Avon Street, Portland, Maine, U.S.A. Oct. 13, 1932, No. 28641. [Class 106 (i).] A device for machanically dividing an integer into a given number of parts comprises an invariable scale the total working length of which is adjustable to be equivalent to the integer, together with an extensible scale element formed by a plurality of consecutively numbered discs having means to space them equally within the working length of the scale. The discs 7, Figs. 2 and 4, are consecutively numbered and slidably mounted on a shaft 6. Each disc has a pointer 8 indicating on the invariable scale 9a. Between the discs are conical spacing members 12 loosely mounted on a shaft 11 which can be lowered towards the shaft 6 by turning a handle 17 connected to eccentric bearing means 14. If, say, 25 is to be divided into 30 equal parts, the end disc (No. 30) is set opposite graduation 25 and a collar 25 is secured to the shaft 6. The shaft 11 is then lowered to space the thirty discs 7 equally along the graduation of the scale 9a. In the embodiment shown in Fig. 11, the device is adapted for monetary calculation and the invariable scale is divided into eight parts 9a .. 9h, each long enough to contain thirty main graduations and each adjacent thirty discs 7. If, owing to depreciation, 240 pence are equivalent to 192 pence, each collar 25 is moved to the left one-eighth of the difference, i.e. 48/8 or 6 units, and the discs 7 are then equally spaced by the members 12. The scales 9b .. 9h are carried on endless bands, which are now adjusted to give a continuous series of markings, as shown. The equivalent value of any other number of pence (on the basis 240/192) can then be read off from the pointers 8. Scales 10a .. 10h facilitate the setting of the collars 25.

Title: Method and Apparatus for the Detection of Variations in the Weight or Thickness of Coatings.
Inventor: BECKLEY PHILIP
IPC: G01G19/00
Filed: 1968-07-17
Abstract: 1,151,131. Photo-electric thickness measurement of coatings. STEEL CO. OF WALES Ltd. July 17, 1968, No.28641/65. Heading G1A. The thickness or weight per unit area of a coating of light reflective material applied to a sheet material is determined by photo-electrically measuring light scattered off the coating, an alarm being operated if the coating thickness or weight per unit area deviates from a reference value. A coating of calcium, magnesium or aluminium oxide is applied to a steel strip to prevent turns of the strip when coiled from being welded together upon annealing. Before coiling, the thickness of the coating is determined by scanning together a light source and a photo-cell, back and forth across the width of the moving coated sheet, at one edge of which the light source and photo-cell momentarily scan a standard reflective surface. The photo-cell receives light scattered off the coating or standard surface and is shielded from any specularly reflected light. The photo-cell output signal passes to a cathode follower and integrating circuit in which from a potentiometer the mean signal is taken for recording. For the short period when the standard surface is being scanned the mean signal is switched from the recorder for comparison with a reference signal; any out of balance due to dirt accumulating on the scanning apparatus adjusts the potentiometer accordingly. An alarm is sounded if the signal from the cathode follower falls below, or rises above, a predetermined value; the alarm circuit Fig.5 (not shown) fails safe. Interference by ambient light is avoided by modulating the scanning light and arranging for the circuit to be sensitive to the modulation frequency.
