Title: Improvements in or relating to incandescent electric lamps
IPC: H01K1/24
Filed: 1933-11-20
Abstract: 428,236. Supports for electric incandescent lamp filaments. GROTE, E. R., c/o British Electric Lamps, Ltd., Spencer Hill Road, Wimbledon, London. Nov. 20, 1933, No. 32300. [Class 39 (ii)] The filament 4, Fig. 1 of a tubular electric lamp is mounted upon pigtails 3 carried by a longitudinal supporting-tube 2 which is maintained in position by resilient saddles 7 formed from flat metal strip bent to a shallow U- shape with a central yoke portion adapted to clip upon the tube 2, and outwardly extending limbs 9 which bear upon the inner wall 1 of the lamp. The saddles are preferably made of stainless steel. Rotation of the tubular filament support 2 relatively to the saddles is prevented by securing within the former a small upstanding wire loop 8, Fig. 3, in line with the pigtails 3, so that it will be engaged between the limbs of a saddle 7. To prevent longitudinal movement of the filament support each leading-in wire 5 is provided with a right-angled bend 5<a> which engages the adjacent end of the tube 2, the horizontal portion of the leading-in wire preferably being pinched within the bottom portion of the saddle at 7<a>. The leading-in wires 5 are subjected to tension during the process of sealing them within the pip 6, thereby retaining the free ends of the limbs of the saddles against the inner wall of the lamp body 1. The yoke of a saddle may be extended in both directions 9<a> to provide means for connecting the ends of two lengths of filament support 2. Specification 304,882, [Class 39 (ii)], is referred to.

Title: Synthesis of hydrocarbons
IPC: C07C1/04
Filed: 1955-11-14
Abstract: In a process for the synthesis of hydrocarbons in which carbon monoxide and hydrogen are reacted at an elevated temperature in the presence of an activated iron-base catalyst, the catalyst contains from 0.1 to 5 per cent by weight of lead.  Preferably the lead is introduced as a volatile compound such as tetramethyl lead, tetraethyl lead, tetrapropyl lead, diethyldipropyl lead, or diethyldibutyl lead in the synthesis gas and is then decomposed at 200-450 DEG  F., thus distributing lead throughout the catalyst bed. In an example, a magnetic iron concentrate was crushed and ground to a particle size range of 0.74-0.246 mms., after reduction with hydrogen for 24 hours at 525 DEG  C. synthesis was started using a gas consisting of 2 parts of hydrogen and 1 part of carbon monoxide and then tetraethyl lead was slowly added to the feed.  The olefins in the C2-C4 fraction rose from 33 to about 90 per cent, although the actual conversion dropped.ALSO:In a process for the synthesis of hydrocarbons in which carbon monoxide and hydrogen are reacted at an elevated temperature in the presence of an activated iron-base catalyst, the catalyst contains from 0.1 to 5.0 per cent by weight of lead.

Patent GB-781487-A (GB)
Title: Improvements relating to lubricating oil compositions
Filed: 1954-11-16
Abstract: A lubricating composition, especially suitable for the lubrication of the cylinders of internalcombustion engines operating on residual fuels, comprises a stable emulsion of water-in-mineral lubricating oil containing 0.5-10 per cent by weight, based on the whole composition, of an additive in the form of a stable dispersion of undissolved particles and consisting of one or more of the following metals and/or inorganic compounds:-magnesium, zinc, oxides of magnesium or zinc, and such water-insoluble inorganic compounds of magnesium, zinc, or the alkaline earth metals, as decompose to oxides on heating.  The preferred additives are magnesium oxide (levis), basic magnesium carbonate (levis), calcium hydroxide and calcium carbonate.  In preparing a lubricating composition containing a dispersion of an alkaline earth metal hydroxide, the oxide may be used since this yields the same lubricant as would be obtained by using the hydroxide.  In order to produce a stable water-in-oil emulsion it is necessary to use an emulsifying agent, for example the fatty material "Emocithine G" (the word "Emocithine" is a Registered Trade Mark), the calcium petroleum sulphonate "Anglamol 64" (the word "Anglamol" is a Registered Trade Mark), or a mixture of sorbitan mono-oleate and lanolin.  In the examples, lubricating compositions are described consisting of water-in-mineral lubricating oil emulsions with a mixture of "Emocithine G" and "Anglamol 64" as the emulsifying agent, and either the calcium hydroxide known under the Registered Trade Mark "Limbux" or the soap-coated calcium carbonate known as "Pattinson's Brand Activated Calcium Carbonate" (the word "Pattinson's" is a Registered Trade Mark) as the inorganic additive. According to the first Provisional Specification, a stable water-free dispersion of the inorganic additive in the mineral lubricating oil, prepared with the aid of montan wax or oxidized montan wax as dispersing agent, may be employed instead of an emulsion.

Title: Improvements in or relating to optical apparatus
IPC: G02B5/00
Filed: 1948-12-31
Abstract: 687,654. Optical apparatus. GENERAL ELECTRIC CO., Ltd., and ROLLIN, L. Dec. 30, 1949 [Dec. 31, 1948], No. 33669/48. Class 98 (i). An optical apparatus comprises a member containing an array of apertures, a plurality of shutters equal in number to the sum of the numbers of rows and columns of said array, each row and each column of the array being separately covered by a single one of the plurality of shutters when that shutter is in the closed position and electrical means for opening or closing each of the shutters independently, the arrangement being such that any one or combination of more than one of the apertures may be uncovered or covered by opening or closing respectively the shutters covering, in their closed position, the row or rows and the column or columns of said array which intersect at the said one or combination of more than one of the apertures. The optical apparatus shown is for use in a multiple recording apparatus which is described in Specification 687,653, [Group XIX], and includes an illuminated slit and a support 2 including compartment 3 for the reception of light-sensitive material. The apparatus comprises an array of lenses 4, four shutters 5, each of which consists of a length of metal foil of width sufficient to cover a lens 4 and of length sufficient to cover the six lenses of one row in the array and six shutters 6 disposed beneath the lens array. The shutters 6 are the same as the shutters 5 and, when operative, are rolled up on rotatable shafts which extend at right-angles to the shafts 7 carrying the shutters 5; normally, each shutter is held in its operative position over a row or column of the lens array by a balance weight, attached to the free end of the shutter. Thus, in order that light may pass through any one lens 4, one of the shutters 5 and one of the shutters 6 beneath the lens array must be rolled on to the respective shafts carrying them. Ten electromagnets are provided, one for co-operation with each shaft, so that the latter is rotated and the shutter carried thereby opened when the relay is energized. Each relay has a slidable armature 9, a side arm 10 on which engages a spindle 11 eccentrically mounted on a disc 12 attached to one end of a shaft 7 so that axial movement of each armature 9 is translated into rotational movement of a shaft 7. The ten relays are controlled by the switching of a six-bank twenty-five contact uniselector. Alternatively, two electric motors, one for the shutters 5 and one for the shutters 6 may be used, the shutters being driven from the appropriate motor through clutches which are operated by electromagnetic means. Each shutter may consist of a relatively rigid sheet of foil carried by a shaft for rotation therewith through a right angle.
