Title: Improvements in electric induction regulators cooled by forced draught
IPC: H02K9/04
Filed: 1920-07-15
Abstract: 149,284. Akt.-Ges. Brown, Boveri, et Cie. July 15, 1919, [Convention date]. Regulating transformers.-An induction regulator is cooled by means of a fan b, the current of air from which enters the regulator symmetrically in two parallel branches e through the end bearing plates d and passes out again through two apertures situated symmetrically on the sides of the stator. The current of air passes partly through the air gap h and longitudinal and radial passages g, i in the rotor and stator iron, and partly through adjustable gaps k on both sides of the stator iron, into an annular space w between the back of the stator iron and the casing. This space communicates with the outflow apertures, which are provided with perforated covers. The flow of air through the regulator is controlled by adjusting the gaps k by means of sector-shaped plates r, Fig. 3, carried by bolts s adjustably mounted in plates t secured to ribs u on the edge q of the casing. The outflow apertures may also form the terminal apertures of the regulator.

Title: Electric floor polishing machine and waxing attachment
IPC: A47L11/16
Filed: 1921-08-15
Abstract: 180,621. Robinson, G. E., and Stencel, R. A. May 23, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Floors, cleaning.-A waxing and polishing machine comprises apparatus for spreading wax, a fan for blowing air upon this wax to dry it, and polishers driven by an electric motor, the polishers being spring-pressed upon the floor so as to polish uneven portions. The casing 2 of the machine is supported on castors 19 and carries the motor 1 which drives the fan 3 and pulley 4, thus rotating three pulleys 6 by means of the belt 5. Thrust bearings 9 are provided at the upper ends of the shafts 8 fixed to the pulleys 6, and the lower ends are made elliptical as shown at 43 to fit in elliptical holes 14 in the backs of the polishers 7 so that vertical movement of the polishers is allowed, springs 15 keeping them pressed upon the floor. The waking- apparatus comprises a box 25 adapted to be filled with wax, which is forced out through the open bottom by a spring-pressed plate 26, the cover 36 being displaced as at 41 during use. Pressure is put upon the wax as required by turning the nut 28 on a stem 27 fixed to the plate 26, so as to allow the spring 29 to come into action. A scraper 31 levels the wax and the air blast dries it so that the floor may be polished immediately by the rotating polishers and finished off by a soft pad 20 extending around the casing 2. The machine is guided by a pivoted handle 23, and may be used for polishing alone by releasing the fixing-nut 33 of the waxing-apparatus and moving this up clear of the floor, for which allowance is made by means of a slot 34.

Abstract: 1,141,619. Alumina sol. UNIVERSAL OIL PRODUCTS CO. 17 May, 1966 [25 May, 1965], No. 21783/66. Heading C1A. In the preparation of alumina sol by digesting impure aluminium metal containing more than 0À01 wt. per cent of metallic contaminants in aqueous mineral acid, the non-colloidal contaminant metal particles which develop in the sol during digestion are mechanically (including magnetically) removed therefrom either subsequently to the digestion or at least partly concurrently therewith, a high-purity sol thereby being obtained. Particle removal may be effected by filtration, centrifugation, or, when the contaminant comprises iron or nickel, by magnetic separation, performed on a stream of sol withdrawn from the digester, at least a portion of the thus treated sol then optionally being returned to the digester. Alternatively, magnets or electromagnets may be placed in or around the digester to collect the dross particles. The aluminium is preferably in subdivided (e.g. pelletized) form and an excess thereof maintained in the digester. The acid may be HCl, H 2 SO 4  or NHO 3 . Exemplified digestion conditions are a temp. of 27-149 C. and a pressure of 0-2À38 atm. gauge.
