In a probe for a scintillometer of the type whereby light is conveyed from crystal to photomultiplier by means of a light guide (quartz &c.) compensationis arranged for inaccuracies of measurement introduced by the luminescence produced in the light guide material by the radio-active radiation being investigated, the direct pick-up of radiation by the photomultiplier and the photomultiplier dark current. The light guide is split longitudinally into two parts A and B, which parts are held apart by the spacers 1, 2, 3 and 4 and contained in the light-tight housing E, the surface of each guide being treated to obtain substantially the condition of total internal reflection. The guide B is extended to house the crystal C, e.g. diamond, which forms the scintillating element. Light from either part of the guide can be directed on the cathode F of the photo-multiplier G via the shutter M which can be moved to either of the two positions by the magnetic coil assembly M1 and M2. In operation the luminescence produced in each part of the guide is approximately equal and the same amount of direct pick-up is received in each shutter position, the scintillometer is adjusted for zero reading with the shutter positioned to pass light from guide A to the photomultiplier cathode. On switching to accept light from the crystal via guide B a reading is obtained compensated for inaccuracies. The probe is designed for medical or geological use or as a detectoscope in industry.

Title: Method of protecting silverware from tarnish
IPC: C23F11/02
Filed: 1949-02-18
Abstract: 669,058. Wrapping silverwear. GREAVES, C. G. T. (Oneida, Ltd.). Feb. 18, 1949. No. 4512/49. Classes 94(i) and 94(ii). [Also in Group VIII]. Silverwear is protected against tarnishing by wrapping it in a material impregnated with a zinc carbonate or zinc borate. According to one example, the wrapping material such as a piece of cloth is first placed in a bath of zinc acetate solution and then immersed one or more times in a bath containing an aqueous solution of sodium carbonate to form an insoluble zinc carbonate and sodium acetate, sufficient sodium carbonate being present to ensure that an excess is retained in the cloth. The cloth is then rinsed in water to remove some of the excess carbonate and acetate, passed through squeeze rolls and finally dried. According to a second example, the cloth is first impregnated with zinc acetate and then immersed in an aqueous solution of borax to form an insoluble zinc borate and sodium acetate. In both cases the pH of the mixture of salts impregnated in the cloth is adjusted to a value between 7 and 8.5 by adjusting the amounts of sodium carbonate or borax and sodium acetate retained in the cloth. In use, the zinc carbonate or borate reacts with hydrogen sulphide to form a white zinc sulphide which does not alter the colour of the cloth. The acid which is also formed is neutralized by the sodium salts.
