Abstract: 376,292. Vacuum-cleaners. RILEY, A., Moor House, Fillongley, near Coventry. April 7, 1931, No. 10208. [Class 8 (i).] A device for washing, sweeping, or cleaning a floor by suction, is mounted upon a movable carriage guided by a rail adjacent the side of the floor. The device may be used for treating the floors of a number of rooms on a common level, openings being provided in the walls to permit passage of the device. As shown in Figs. 2 and 3, a cleaning device 4 is mounted for reciprocation on a carriage 5 which is provided with rollers 6 running on rails 7. One of the rails has rack-teeth to engage a pinion 9 fixed to the spindle 10 which is driven by an electric motor. The motor serves to operate the cleaning device and also to cause it to slide across the carriage, means being provided for reversing its motion at the end of its travel in each direction. In a modification the device is reciprocated on the carriage by means of an endless chain arrangement, and is adapted to operate clutch mechanism at the end of each transverse movement whereby the carriage is moved for a short distance along the rails 7. In the arrangement shown in Fig. 2, a number of rooms 12 on the same level are on both sides of a central passage 13, and rails 7 extend through all the rooms to guide the device 4. Openings 3 are provided in the walls, 2, 14 to allow the device 4 to pass, these openings being preferably closable by hinged strips 23 which may be raised by hand or automatically on the approach of the cleaning device. The device when not in use may be stored under a false floor 15. To facilitate cleaning operations, furniture may be provided with hinged legs or may be fixed to the walls of the rooms by lazy tongs or hinged arms so as to be easily raised to allow the device to pass underneath. According to the Provisional Specification the cleaning operations include polishing.

Title: Control of molecular weight of polymers
IPC: C08F20/12
Filed: 1958-03-31
Abstract: Esters of acrylic and methacrylic acid, the alcohol moieties of which are free of reactive hydrogen, are polymerized in an inert solvent under anhydrous conditions at a temperature below 0 DEG C. under the influence of a catalyst mixture comprising a first catalyst based on sodium or potassium and a second catalyst based on lithium, calcium, strontium or barium, at least one of the two catalysts being a salt of a Lewis acid having a pKa from 16 to 36, the ratio of the first catalyst to the second catalyst being so selected that the viscosity average molecular weight of the polymer produced is in the range from about 90,000 to about 1,500,000.  Esters specified are the alkyl, cycloalkyl, aryl, aralkyl, alkaryl, alkoxyalkyl, aryloxylalkyl, aralkyloxyalkyl, cycloalkoxyalkyl, amino alkyl, alkenyl, tetrahydrofurfuryl and isobornyl acrylates and methacrylates, preferred being the C1-C8 alkyl, C3-C18 alkenyl, phenyl, benzyl or alicyclic esters.  The process may be employed to produce homopolymers of the above esters or copolymers of the esters with one another.  The catalyst mixtures may be made in various ways, e.g. (1) the two metals may be dissolved in liquid ammonia and then titrated with methyl isobutyrate, methyl crotonate, butyl acetate, butyl propionate or diethyl malonate to provide the metal alkoxide by hydrolysis of the ester; (2) one of the metals is mixed with a salt of one of the other metals and the free metal is then titrated with a Lewis acid; (3) one of the metals is dissolved in a solvent and titrated with a Lewis acid followed by the addition of a salt of one of the other metals; and (4) the two metals are dissolved in liquid ammonia through which oxygen is bubbled to produce the metal amides. Additionally the metals may be used in the form of their aryls, aralkyls, diphenylamides, indenyls or cyanides.  The molecular weight of the polymer products is controlled by varying the proportions of the constituents in the catalyst, the way in which the proportions are varied depending upon whether it is an acrylic or a methacrylic ester which is being polymerized.  The polymer products may be used in coating and moulding applications.

Title: Electronic fluorescent illuminating lamp
IPC: H01J61/42
Filed: 1953-04-16
Abstract: 749,448. Fluorescent discharge lamps. SEBEL SOC. ANON. April 16, 1953 [April 22, 1952; Jan. 28, 1953], No. 10476/53. Class 39 (1). A fluorescent lamp of the high-vacuum type has an anode 14, Fig. 1, coated on the tube wall and carrying a fluorescent coating 6 and two grids 12, 13 screening the indirectly heated cathode 2 from the anode 14, grid 12 being at cathode potential or slightly negative relatively thereto and grid 13 being positive relatively to the cathode grids 12, 13 being of the same pitch and having aligned elements so that the elements of grid 13 are in the electronic shadow of grid 12. The negative grid 12 focuses the beam so that the positive grid collects few electrons, i.e. about 3-5 per cent. The cathode and grids can be arranged coaxially in a cylindrical prismatic or parallolepipedic form. In Fig. 1 the cathode and grids are carried by mica washers 10, 11; the grids may be helices of circular or rectangular section secured to bars 15. Grid 13 may be connected to anode 14 which may be formed by spraying. If the fluorescent coating 6 emits ultra-violet light, the upper wall of the bulb can be coated with a photoluminescent substance to transform the ultra-violet to visible light. Alternatively the anode may be formed by the tube wall which is made of conductive glass. In this case the fluorescent coating may be over the whole inner surface of the tube. The heater 9 is of tungsten coated with alumina. To avoid extinction of fluorescence due to infra-red rays produced by the cathode, the cathode and grids are made flat and parallel to one another but extend perpendicular to the tube axes, Fig. 2 (not shown), so that the infra-red rays pass out through the uncoated portion of the envelope.

Title: Improvements in or relating to the preparation of pentaerythritol
IPC: C07C31/24
Filed: 1948-04-16
Abstract: Pentaerythritol is produced by the reaction of acetaldehyde and formaldehyde in an aqueous alkaline medium in the presence of a catalytic quantity of one of the following substances as catalyst: glycollic aldehyde, glyceraldehyde, dihydroxyacetone, di-(beta-hydroxyethyl)-ketone, ethylene glycol, glycerol, and the residue containing organic substances remaining after formaldehyde and acetaldehyde have been reacted in an aqueous alkaline medium to produce pentaerythritol and the pentaerythritol has been separated therefrom.  The catalyst is preferably added to the reaction mixture prior to the commencement of the reaction and the reaction is preferably carried out at a temperature not exceeding 55 DEG  C.  The process may be carried out batch-wise or continuously.  In the continuous process acetaldehyde, formaldehyde, an aqueous alkaline medium and a catalytic quantity of the catalyst are continually fed to a reactor from which the resulting reaction mixture is withdrawn at such a rate as to maintain the volume therein substantially constant.  In examples: (1) a small amount of glycerine is added to an aqueous lime slurry and the mixture heated to 30 DEG  C.  An aldehyde solution containing formaldehyde and acetaldehyde is then added the temperature being finally raised to 50 DEG  C.  After cooling and adding sulphuric acid to precipitate the calcium as sulphate the mixture is filtered and pentaerythritol crystallized out by vacuum evaporation of the filtrate; (2) and (3) the process is effected in a similar manner to (1) except that the catalysts used are ethylene glycol and di-(beta-hydroxyethyl)-ketone respectively; (4) the process is carried out continuously by adding the mixed aldehyde solution and an aqueous lime slurry containing ethylene glycol to a reactor of a conventional laboratory system after uniformity of operating conditions have been reached.  The temperature of the reactor being maintained at 25 DEG  C.  U.S.A. Specification 2,329,514 is referred to.
