Abstract: 416,962. Photometric apparatus. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Hardy, A. C. ; 28, Upland Road, Wellesley, Massachusetts, U.S.A.) Dec. 7, 1933, No. 34455. Convention date, March 10. [Class 97 (i).] In apparatus comprising a photoelectric cell receiving light alternately from a test source and from a standard, an optical system for controlling the light received by the cell comprises an angularly movable polarizing member, a double-image prism dividing the light incident upon it into two beams polarized in planes at right-angles, and a second polarizing member. The first polarizing member is continuously rotated and the second is angularly adjusted in accordance with the output of the photoelectric cell. As shown, the first polarizing member, comprising a Nicol &c. prism 10 is mounted within the hollow shaft 14 of a synchronous electric motor 16 and the second polarizing member 11 is mounted within a sleeve 20 rotatable by a knob 26 and having a pointer 21 moving over a scale 22. The double-image prism 12 is disposed between the members 10, 11. The light leaving the member 11 is received by the photoelectric cell 3, the output from which passes through an amplifier 4 to a vibration galvanometer 5. The member 11 is rotated by the knob 26 until the indicator 7 of the galvanometer is stationary ; the reading of the pointer 21 then gives the relative luminosity of the sources 1, 2. These are shown as primary sources, but they may consist of two different reflecting surfaces both receiving light from the same primary source. These surfaces may be arranged beyond the cell 3 so that the light from the single source passes through the members 10, 12, 11 before reaching the surfaces. In such an arrangement a spectroscope system may be arranged between the light source and the member 10 so that the surfaces can be illuminated bv monochromatic light. The light source and the slit plate of the spectroscope may be angularly adjustable to enable any desired part of the spectrum to be used. The two surfaces to be compared may be disposed within an integrating sphere having an outlet adjacent the photoelectric cell. The member 11 may be adjusted automatically by an electric motor controlled by the output from the cell. Specifications 291,397, [Class 97 (i)], and 341,200 are referred to.

Title: Load-operated electric switch and an alarm system using such switch
IPC: G01L1/04
Filed: 1977-08-19
Abstract: A pressure operated electrical switch and an alarm system for use in hospitals and nursing homes is constructed such that a force is applied to a pressure plate therein. Once the load is reduced below a predetermined value the pressure plate will move under spring influence to close/open a microswitch or electrical contact means. The normal force applied to the pressure plate is the load on the leg of the hospital bed when occupied. If the bed occupant gets out of the bed the load on the pressure plate is reduced below a predetermined value, and the consequent movement of the pressure plate opens/closes the switch means to actuate the alarm.

Title: Process for the preparation of 2.4.6 trialkylated phenols
IPC: C07C43/178
Filed: 1957-11-11
Abstract: The invention comprises a process for the preparation of a 2,4,6-trialkyl-phenol by reacting a 2,6-dialkyl-phenol with a C1-C8 acyclic saturated aldehyde, in the presence of a C1-C6 alcohol and an alkaline metal hydroxide, the reaction mixture having a pH greater than 7, and hydrogenolizing the 4-alkoxyalkyl-2,6-dialkyl phenol so formed in the presence of a hydrogenation catalyst.  The aldehyde used should preferably contain not more than 4 carbon atoms per molecule and the alcohol used is preferably methanol, although ethanol, propanol, isopropanol and butanol are also specified. Aldehydes specified are formaldehyde, paraform, acetaldehyde, propionaldehyde, n-caproaldehyde.  A compound forming formaldehyde under the reaction conditions may also be used.  Suitable alkaline metal hydroxides are, e.g., sodium or potassium hydroxide.  The alkyl substituents in the starting materials may be the same or different and preferably contain up to 6 carbon atoms.  The reaction is preferably carried out using 1.05 to 7 mols. of aldehyde and about 5 to 30 mols. of alcohol per mol. of 2,6-dialkyl phenol, the pH of the solution preferably being between about 9 and 12.  The preparation of the ether may be carried out between about 35 DEG  to about 100 DEG C. or higher. Bis-phenol by-products, e.g. 4,41-methylene bis-(2,6-ditert.-butylphenol), 4,41-methylene bis(2,6-diisopropylphenol) are formed during the ether preparation, and may be removed by distillation at reduced pressures, e.g. 1 to 5 mm. or more at about 100-175 DEG  C., although the hydrogenolysis step is preferably carried out immediately, without separation of the byproduct.  The hydrogenolysis may be conducted in the liquid phase in e.g. C1-C8 alcohols, n-alkanes, or aromatic hydrocarbons at e.g. 110-170 DEG  C., and 100-700 p.s.i.g. or higher, wherein a substantial portion of the pressure may be due to the partial pressure of the solvent. Suitable catalysts are preferably selected from metals of Groups I, II, IV, V, VI, VII and VIII of the Periodic Table, their alloys and derivatives such as their sulphides, oxides and chromites, e.g. silver, copper, iron, manganese, molybdenum, platinum, chromium cobalt, rhodium, tungsten, nickel, copper-silver mixtures, copper-chromium mixtures, nickelcobalt mixtures, and their derivatives.  Copper chromite is the preferred catalyst. The catalysts may be finely divided and dispersed or supported on an inert carrier, e.g. pumice, kieselguhr, diatomaceous earth, clay alumina, charcoal or carbon, suitable amounts of catalyst are from about 0.1 per cent to 35 per cent by weight of the ether. After the hydrogenolysis the by-product is separated from the reaction product. Examples are given of the preparation of the following compounds: 4-methoxymethyl - 2,6 - ditert. - butyl phenol, 4 - ethoxymethyl 2,6 - di - isopropyl phenol, 4,41 - methylene bis (2,6 - diisopropylphenol), 4 - (1 - methoxyethyl) - 2,6 - ditert. - butyl phenol, 2,6 - di - tert. - butyl p - cresol, 2,6 - diisopropyl p - cresol, and 4-ethyl-2,6-ditert.-butyl phenol.
