Title: Optical relay device particularly for use in television
IPC: G02F1/00
Filed: 1969-12-17
Abstract: 1287767 Television display systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 17 Dec 1969 [20 Dec 1968 (2) 5 Feb 1969] 61513/69 Heading H4F In the system described in Specification 1,160,923, the temperature of a plate composed of a deuterium enriched acid salt exhibiting the Pockels effect is stabilized near to its Curie temperature, i.e. below which it becomes ferroelectric, using as a temperature sensor a capacitor having a dielectric if the same material as the plate. However the optimum operating temperature is also the temperature at which the dielectric constant of the salt is a maximum, giving low sensitivity to temperature charge, and it is now proposed to use a capacitor which has a dielectric the Curie temperature of which varies from that of the plate by, e.g. 5-20‹ C. Thus the plate may be formed of a salt 80-100% substituted with deuterium and the dielectric of the capacitor may be the same salt with 5-20% less deuterium. Modification of the embodiments described in Specification 1,160,923 include: (a) the use of a lens shaped fluoride plate (66) to replace a condenser lens, Fig. 9 (not shown); (b) the use of a double "Glazebrook" prism and a quarter or half wave plate with associated plane and curved mirrors to use all, instead of only half, of the incident light, Figs. 10-12 (not shown). Fig. 13 (not shown) illustrates the use of two slightly inclined, spaced mirrors, to avoid production of shadows by the light source.

Patent GB-2031948-A (GB)
Title: Foods, beverages and fodder with a reduced content of histamine
IPC: A23K1/165
Filed: 1979-08-20
Abstract: A process for producing foodstuffs, beverages and forages with a reduced content of biogen amines and preferably with a reduced content of histamine is described. People with good health are able to degradate histamine which they take up with food by a histaminase. Nevertheless, many people, female and male, are not able to perform a sufficient degradation of the histamine and if these people take up histamine this results in severe troubles, like headache, a development of gastric ulcera, diarrhoea, as well as several kinds of allergic reactions. If histamine is present in forages, like e.g. in silo-fodder, then the histamine passes over into the milk and accordingly also into the diary and products, so that it is desired to have not only foodstuffs but also forages available with low histamine levels or completely histamine free. It now was found out unexpectedly that foodstuffs, beverages and forages having a drastically reduced histamine content or being completely free of histamine can be prepared by adding during any desired step of the preparation of the foodstuff, beverage or forage a microorganism which performs a transamination or desamination of histidine, or an enzyme which results in a transamination or desamination of histidine. According to said process the histidine can e.g. be converted by a primary splitting off of ammonia into the innocuous glutamic acid. The new process is especially important for the production of such foodstuffs, beverages or forages, in which an essential step in the course of the preparation of said products is a conversion performed by a micro-organism like e.g. an alcoholic fermentation or a lactic fermentation. The naturally occurring microorganism strains generally perform a decarboxylation of histidine present in the starting material forming the undesired histamine. The new process makes it possible to produce such foodstuffs, beverages and forages which generally have a high histamine content, like e.g. alcoholic beverages, sour-milk products, pickled cabbage and silo-fodder, nearly or completely free of histamine.
