Abstract: A fuel for internal combustion engines comprises hydrocarbons in the gasoline boiling range containing a minor proportion of a tetra alkyl lead and a minor proporton of a mixture of a halohydrocarbon scavenger and up to 0.4 theories of a triester of orthophosphoric or phosphorous acid, this ester containing at least one aryl radical attached through an oxygen atom to the phosphorus atom, which aryl radical may be substituted by alkyl groups of 1 to 3 carbon atoms, and the ratio of theories of halohydrocarbon scavenger to theories of said triester lying between 3 : 2 and 15 : 1.  The halohydrocarbon scavenger may be ethylene dichloride or dibromide, acetylene tetrabromide, hexachloropropylene or the mono- or poly halo propanes, butanes, pentanes or alkyl benzenes.  More than one such compound may be employed.  The triester may be tri-o-cresyl orthophosphate, tricumenyl orthophosphate, propyl di-p-cresyl phosphite, triphenyl phosphite or tri-p-cresyl phosphite.  The total amount of scavengers is generally between 0.4 and 2 theories based on the lead present, and preferably between 0.9 and 1.2 theories.  The triester of orthophosphoric or phosphorous acid is preferably present in an amount between 0.1 and 0.3 theories.  The fuels may also contain corrosion or oxidation inhibitors, such as 2.4-dimethyl-6-t-butyl phenol and other alkyl phenols, N:N1-dibutyl-p-phenylene diamine, hydroquinone and phenyl-alpha-naphthylamine, and dyes.  The Specification also describes compositions for adding to gasolines, comprising the mixtures of the two scavengers and tetra alkyl lead.

Abstract: 743,681. Electric measuring systems. LAND PYROMETERS, Ltd. May 12, 1954 [May 18, 1953], No. 13807/53. Class 40(1) The difference in pressure between the inside and outside of a furnace is determined by locating a thermocouple centrally in a tube in the furnace wall, whereby the thermocouple output will indicate whether cold air is entering the furnace from outside, i.e. the pressure inside is lower than outside, or vice versa. The thermocouple comprises the dissimilar metals A, B (Fig. 2) each consisting of a thick and thin part, producing a thick wire thermojunction 10 responding to the average temperature of the surrounding wall 18 (Fig. 1) and a thin wire junction 11 responding to the flow of gas, the thermocouple output being fed to a centrezero milliameter which indicates the direction and magnitude of the gas flow. The wires are supported in insulators 12, 12<SP>1</SP> inside a metal tube 14 located in a hole 17 in the wall 18. The instrument, may be checked by rotating a sleeve 24 so that its hole 26 covers the outlet hole 23 of tube 14, when the thermocouple output should be zero. The sensitivity may be increased' by using two such thermocouples in series. The two wires of the couple may be of the same thickness with one covered by an insulating sleeve. The instrument readings may be used to control the stack damper either manually or automatically.

Title: Arrangement for testing the quality of photographic objectives
IPC: G01M11/02
Filed: 1962-04-12
Abstract: 1,004,116. Testing lenses. E. GLOCK. April 12,1962 [March 30, 1962], No.14259/62. Heading G1A. The invention relates to a method and apparatus for testing a photographic lens P in which an image of a lamp L is focussed by a condenser lens B on to the stop D of a lens E which forms an image in another condenser formed by two lenses C 1  and C 2  cemented to prisms P 1  and P 2  having a semi-transparent mirror at their interface S. The face of the prism P 2  abutting the lens C 2  has a reticle T composed of an array of strips each strip being a reflecting surface on a transparent ground. The lenses C 1 , C 2  focus an image of the diaphragm D at a micro-objective M which forms . an image T<SP>1</SP> of the reticle T in the focal plane of the lens P under test which in turn forms an image at infinity. This image is then returned along its incident path by an autocollimator A and after returning through the lens P, micro-objective M and lens C 2  impinges on the reticle T, where due to the angular dimensions of the prisms P 1  and P 2  part of the light is reflected to the face of a light guide L 2  (Fig. 4 not shown) which directs the light to a photo-cell F 2 . A further part of the light from the returning image passes between the strips of the reticle and is internally reflected by the interface S and the other short face of the prism P 2  and directed (Fig. 5 not shown) by a lens C 3  on to a light guide L 1  associated with a photocell F 1 . The ratio of the signals from the photocells F 1  and F 2  is said to give an indication of the quality of the test lens. The initial light beam from the source L is reflected by the surfaces of the strips of the reticle T adjacent to the prism P 2  and is internally reflected by the interface S and the short face of the prism P 2  (Fig. 3 not shown) and is directed by lens C 3  on to a light guide L 3  associated with a photo-cell F 3  whose output signal is used to monitor the intensity of the light from the source L. In another embodiment (Fig. 6 not shown) a multiplicity of channels are used, each consisting of all the components of the apparatus from the lamp L to the micro-objective M, to enable simultaneous examination of several points in the field of view of the test lens P.
