Abstract: 388,445. Centrifugal machines. ELECTROLUX, Ltd., 153, Regent Street, London.-(Assignees of Inventia Patent- Verwertungs-Ges. ; 10, Herrenacker, Schaffhausen, Switzerland.) Sept. 2, 1931, No. 24659. Convention date, Sept. 3, 1930. [Class 23.] A washing-machine is provided with two containers 13, 14, Fig. 1, which are oscillated out of phase with one another from a common drive-shaft 24 whereby the torque on the drive-shaft due to the inertia of one oscillating container counterbalances that due to the other container so that the resultant torque is substantially zero. A worm wheel 25 constantly driven by a worm shaft 40 is clutched to the shaft 24 when a coupling member 55 is in the position shown in Fig. 1, the coupling member being slidable along the shaft and provided with a pin 57 engaging a slot 56 therein. The container 13 is oscillated by a crank 23 and connecting-rod 22 and the container 14 is oscillated by a crank 42 arranged beneath the crank 23 and pivoted to a rack 43, Fig. 2, which engages a pinion 34 on the shaft 30 of the container 14. The rack and connecting-rod are so disposed that when one container is at an end of its stroke the other container is at the middle of its stroke and the transmission ratios are arranged to compensate for the different masses of the two containers. The rack is kept in engagement with the pinion by means of an arm 45 loose on the shaft 30 and provided with a pin 46 which engages a longitudinal slot 47 in the rack. The coupling member 55 may be moved out of engagement with the worm wheel 25 to disconnect the oscillating mechanisms by manually rotating a shaft 48, Fig. 1, which is provided with forked arms 50, 51. The forked end of the arm 50 engages the coupling member and the forked end of the arm 51 engages a conical member 35 which is slidable along the shaft 30 and is provided with a pin 37 engaging an axial slot 36 therein. When the oscillating mechanisms are declutched the conical member 35 is therefore simultaneously raised into engagement with a conical sleeve 33 secured to a constantly driven worm wheel 32 loose on the shaft 30 whereby the receptacle 14 is rotated for centrifugally drying the clothes therein. The jacket 26 surrounding the receptacle 14 is provided with a draining channel 64. The water is discharged from the receptacle 14 through the apertures 63 and the receptacle is provided with an outwardly directed rib 66 to prevent water from passing down on to the casing 20.

Title: Improvement in acetals of pyruvic aldehyde
IPC: C07C49/175
Filed: 1944-12-12
Abstract: Pyruvic aldehyde is heated with a monohydric alcohol, water being distilled from the mixture at a temperature between 50 and 100 DEG C., and an acetal of pyruvic aldehyde recovered by fractional distillation.  An inert water-immiscible organic liquid boiling below 100 DEG  C., and an acid catalyst may be present.  Towards the end of the reaction, a slight rise in temperature is allowable. Removal of the water of reaction may be effected as an azeotrope with the water-immiscible organic liquid, e.g. benzene, diisopropyl ether, ethyl acetate, and ethylene dichloride, or by distillation under reduced pressure.  The pyruvic aldehyde may be in monomeric or polymeric form, hydrated or not.  A crude aldehyde containing water and monoaldehydes, for example from oxidation of propylene glycol, may be used.  Alkyl, chloralkyl, and alkoxyalkyl alcohols such as isopropanol, butanol, 2-ethylhexanol, lauryl alcohol, cyclohexanol, 5-ethylnonanol-2, 7 - ethyl - 2 - methylundecanol - 4,3,9 - diethyltridecanol-6, b -chlorethyl and b -chlorisopropyl alcohols, methoxy-, butoxy-, and butoxyethoxy-ethanols yield acetals the lower members of which are solvents for oils, fats, resins, waxes, and cellulose derivatives.  In examples: (1) an aqueous pyruvic aldehyde containing formaldehyde is heated with butanol, benzene, and sulphuric acid at about 85 DEG  C., the water distilling as azeotropes with butanol and benzene.  The latter are returned after separating the water, and the temperature rises to 104 DEG  C. at the completion of the reaction.  Pyruvic aldehyde dibutyl acetal is recovered by fractionation.  In the absence of the benzene, there is substantial conversion to butyl ester of a -butoxy propionic acid, and formation of pyruvic aldehyde dibutyl acetal dibutyl ketal; (2) lauryl alcohol replaces butanol and the temperature is below 90 DEG C., the dilauryl acetal being obtained; (3)-(6) di-isopropyl, di(2-ethyl hexyl), di-methoxyethyl, and di(b -chlorethyl) acetals are prepared similarly.
