Title: Improvements in electrically driven polishing machines
IPC: B24B23/00
Filed: 1948-12-03
Abstract: 666,242. Electric polishing machines. PEJSEK, A. Dec. 3, 1948, No. 31325/48. Class 19. An electrically driven polishing machine adapted to be operated by one hand, for polishing wood and like surfaces, is characterized in that the electric motor shaft and the polishing spindle are vertically arranged side by side and a link or disc fixed on the motor shaft acts as a bearing for the polishing pad spindle. Fig. 1 is a side view and Fig. 2 a sectional view on line A-B of Fig. 1. The pad 3 may be made of an inner layer of a non-absorbent soft elastic mass 8 with a layer of absorbent polishing material 9 forming the lower part of the textile covering 7. The polish vessel 10 may be divided into compartments for spirit, polish or oil and may be detachably fitted to the polishing head. The hand grip 11 may be detached. The eccentricity provided by the link 15 must leave the centre of gravity of the machine X-X passing through the working face of the pad. The pad rotates about the motor shaft and is freely rotatable about its own axis by reason of the interaction of an internally toothed ring 16 fitted to the casing of the polishing head and a coacting pinion 17 on the spindle of the polishing disc. The openings 17 in the link allow of changes in the eccentricity. Change gearing to suit different eccentricities may comprise pinions of varying sizes exchangeably fitted on the pad spindle and allows of alteration in polishing speeds.

Title: Improvements in processes and apparatus for filtering varnishes or oils
IPC: B01D25/21
Filed: 1922-11-22
Abstract: 208,880. Ward, J. P. Nov. 22, 1922. Filtering varnishes. -Relates to filtering varnishes or oils, such as China wood oil, or other drying oils, liable to detrimental chemical or physical changes during filtering. According to the invention, the filtering takes place within certain limits of temperature and pressure; in the case of China wood oil the temperature is about 60‹ C. and and the pressure 30 to 50 lbs. per square inch. Further, the filtering apparatus employed is of the type in which the cloth is separated from the grooved supporting plate by wire gauze &c. so as to prevent the cloth from being pressed into the grooves and so choking them. This promotes the rapid escape of the filtrate after it has passed through the cloth and so minimizes the time during which chemical and physical changes are likely to occur. Fig. 4 shows a type of filter, adapted for carrying out the process, in which the plates 1 have wide shallow grooves 10, wire gauge 2 supporting the filter cloths, which may be double, as indicated by the broken line 5<1>. In another form, Fig. 6, an inner gauze 2<1>, and an outer gauze 2 are provided, a filter cloth or paper being sandwiched between them and a cloth being supported on the outer surface of the gauze 2.

Patent GB-463453-A (GB)
Title: Improvements in and relating to the manufacture of clay-pozzolana
IPC: C04B28/22
Filed: 1935-11-21
Abstract: Clay-puzzuolana is produced by burning clay in an atmosphere substantially free from sulphur or sulphur compounds at a temperature of 550 to 800 DEG  C.  The firing may be direct, the fuel used being free from sulphur, or an electrically heated furnace may be used. With indirect firing, the clay is placed in substantially closed metal containers which are put into or passed through a kiln. Organic material is removed during the burning by supplying an excess of air in direct firing; for indirect firing, air may have access to the container, or there may be introduced into the container a substance which gives off oxygen during burning.  The raw clay may be broken up to increase the surface, or it may be shaped into rod form.

Abstract: 263,827. Seehaus, P. Dec. 24, 1925, [Convention date]. Heating by electricity.-In a device for storing and utilizing electrically generated heat, the heat is transmitted to the consuming device by a circulating liquid or gas which passes inwards through a porous insulating covering serving in part for the storage of heat. Heat from an electric heater a is stored in part by a relatively small storage mass b and in part by an insulating covering c of superposed plates, sand, or other porous medium. The heat-transmitting medium is circulated by a pump g inwards through the medium c and core b and thence in contact with a cooking plate e and water heater f. The circulation of the medium is regulated by dampers or by the speed of the pump' g. The insulating covering c may be subdivided into superposed coverings having independent means for circulating fluid through them. The inner device may be used for generating steam, and the next for heating feed water. If air is used as the circulating medium, it may be allowed to escape when it has given up heat.
