Filed: 1975-01-24
Abstract: 1477931 Electric analogue calculating DEFENCE SECRETARY OF STATE FOR 24 Jan 1975 [29 Jan 1974] 04172/74 Heading G4G The circuit shown in Fig. 1 is used in the calculation of the visual range R of runway lights at an airfield using meaurements of the transmission of light through the atmosphere. The circuit is in three sections, the first comprising components 1 to 6 (the circles represent potentiometers) which generate a function of the form x=log (# log e), where # is the extinction coefficient as measured by a transmissometer which supplies an input i, use being made of the relationship i=i 0  exp (-#Z) where Z is the optional length of the transmissometer. In Fig. 2 (not shown) # is obtained direct from a nephelometer. The second section comprises components 8 to 12 and generates a function of the form y = log I - log E T , where I is the intensity of the lights and E T  is the illumination threshold of the eye which is calculated from the background luminance B measured by a suitable instrument using an empirical relationship log 10  E T  = K log 10  B-C. The third section 13, 14, 15 interconnected with 7 is used to solve the equation r = log (y - 2r) - x, r being related to the range R by r=log R, the output being obtained at adder 7.
Patent GB-432370-A (GB)
Title: Improvements in or relating to journal bearings
IPC: F16H23/00
Filed: 1934-02-08
Abstract: 432,370. Bearings; lubricating. RIEBE, A., 14, Wendenstrasse, Schmokwitz, Berlin. Feb. 8, 1934, No. 4232. Convention date, Feb. 8, 1933. [Classes 12 (i) and 12 (ii)] In a short length journal bearing with a spherical journal member d, the arc g generating the surface of the bearing is identical in all respects taken in the direction of the bearing axis with the arc c generating the journal surface, the radii R2, R1 of rotation of these arcs about the bearing axis differing from one another by the amount of bearing clearance when the journal and bearing are arranged co-axially. The bearing thus formed gives a theoretical line contact between the relatively rotating parts and when the deformation of the parts is taken into account, it gives surface contact over a longitudinal area. To enable the annular journal member d to be inserted, the bearing is divided into two parts a, b which are mutually guided by the pilot collar i, and secured together by bolts e. The bushing f is similarly divided. For producing an oil layer at the bearing surfaces, an annular passage k is arranged in the parts a, b, said passage communicating by ducts l, m with the bearing surfaces. These bearings are suitable for replacing ball-bearings of comparable bearing capacity. The Specification as open to inspection under Sect. 91 describes means for inserting the journal member d in a one-piece bearing member k and also means for producing an oil circulation. The member k, Fig. 3 (Cancelled), has two opposed recesses or slots l enabling the member d to be inserted and then turned to the horizontal position shown after which it is possible to insert filler pieces n having surfaces corresponding to the internal surface of the member k. The pieces may be retained by end flanges or by bolts, soldering, fish-plates, welding, &c. In another construction, only a single recess and a single filler piece only are provided, the former extending only part of the bearing length and being of dove-tail shape to retain the fillerpiece which is similarly shaped. The method may also be employed with a single recess where a stepped bushing retained by a weldedin end ring is located between the members k, d. The filler-piece in this case is also retained by a radial screw. The filler-piece or pieces may be cast in position and. may be of graphitic metal. The openings for the filler-pieces may be smaller than is necessary for the insertion of the annular member, which is then inserted by shrinking or deformation or by expansion of the outer member. Fig. 17 (Cancelled) shows an opening c<1> leading oil away from the greatest diameter of the bearing surfaces to the reservoir b<1>, whence it returns to the bearing surfaces by means of wicks e<1> in side openings d<1>. The flow of oil in the openings c may be throttled by means of wicks. Another oil-circulating means is shown comprising transverse grooves of varying depth in the member k. This subjectmatter does not appear in the Specification as accepted.
