Title: Devices for measuring  toe in  of motor vehicle wheels
Inventor: HIRMANN G
IPC: G01B7/315
Filed: 1972-07-13
Abstract: 1365772 Measuring "toe-in" of vehicle wheels POLYPRODUKTE A G 13 July 1972 [15 July 1971] 32696/72 Heading G1N "Toe-in" of front wheels of a motor vehicle is measured by engaging pivotted feeler bars 36, 37 with the wheel rims, the angular position of each bar being converted to an electric signal in a differential transformer 47, the core 48 of which is displaceable by either of two pins 41, 40 selectable by pneumatic couplings 44, 45 to sense the position of the feeler bar, pin 41 being twice as far from pivot 38 as is pin 40. Two measurements are taken, the wheels being turned through 180 degrees by rollers 25-28 between measurements, the core 48 being moved by pin 41 during the first measurement and by pin 40 during the second, thereby eliminating wheel wobble errors. Feelers 20, 21 engage the rear wheels to align the measuring apparatus with the longitudinal axis of the vehicle. The distance between the front and rear wheel feelers is telescopically adjustable. The front wheel rim feelers are moved in and out symmetrically by a common pinion 24 engaging respective racks 22, 23. The spacing of the rear feelers is similarly adjustable.

Abstract: 1515805 Determination of creatinine KYOWA HAKKO KOGYO CO Ltd 5 Aug 1976 [28 Aug 1975 11 Sept 1975] 32698/76 Heading G1B [ Also in Division C3] A method for the quantitative determination of creatinine in a sample comprises reacting said sample with a solution of a creatinine desimidase until said creatinine is hydrolyzed to form ammonia and N-methyl-hydantoin and then measuring the amount of at least one of said ammonia and N-methyl-hydantoin formed by said reaction. The reaction may be carried out at 30- 50C for 10-30 minutes and the sample is preferably urine or blood serum. The creatinine desamidase is produced by culturing a creatinine desamidase producing microorganism belonging to the genus Bassibacterium, Corynebacterium, Pseudomonas or Arthrobacter.
Patent GB-538272-A (GB)
Title: Improvements in or relating to films for reducing surface reflection from light-transmitting and other articles
IPC: G02B1/11
Filed: 1939-12-22
Abstract: 538,272. Reducing surface reflection. BRITISH SCIENTIFIC INSTRUMENT RESEARCH ASSOCIATION. Dec. 22, 1939, No. 32793. Convention date, Dec. 27, 1938. [Class 97 (i)] A film for reducing reflection from a surface of an optical element has an effective index of refraction approaching the square root of that of the element, and is deposited thereon by evaporation, its thickness being controlled so as to approximate x/4 times a pre-selected wavelength of light where x is 1 or any odd integer not greater than 9 ; layers of negligible optical thickness may be applied to the surface to increase adhesion of the film, and to the film surface to protect it. The film substance may be a metallic fluoride, e.g. magnesium, lithium, calcium, or sodium, fluoride, or cryolite, or a mixture of substances, and the optical element may be of glass, quartz, plastic compositions such as regenerated cellulose, mica &c. and be a plate, lens, prism &c. Deposition may occur in a chamber which is evacuated to a pressure which may be about 10<SP>-3</SP> mm. of mercury, evaporation being effected by supporting the substance in a basket of resistance wire heated by passage of a current. The deposition may be controlled with the aid of a monitor comprising a surface placed about 5 per cent. nearer to the basket than the surface of the element so that the thickness of the film upon it is always greater than on the surface of the element. Reflected light appears purplish when the film thickness is correct, and deposition is stopped when the appearance of the monitor has changed from purple to bluish. Films suitable for use in the non-visible spectral regions may be similarly controlled by a monitor which is suitably displaced from the position necessary for use with visible light. A relatively thin adhesion layer may be first applied to the surface of the optical element by evaporating chromium on to it in an evacuated chamber, and then breaking the vacuum so that the chromium becomes oxidized. A protective layer of zircon, quartz &c. may be similarly evaporated on to the surface of the deposited film. The optical element may be part of a solar energy receiver. Specification 538,273 is referred to. The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 538,273. This subject-matter does not appear in the Specification as accepted.
