Abstract: disposição construtiva aplicada a painel para cuba de máquinas de lavar roupas. o objeto desta patente coniste nos resultados dos investimentos financeiros em engenharia e pesquisas de mercado para desenvolver uma nova disposição do painel de controle de máquinas de lavar roupas, colocando-o na parte superior interna da cuba de lavagem, a qual pode ser ampliada e aumentar a capacidade de carga e lavagem das mesmas, sem aumento de preços, o que consiste em uma vantagem competitiva aprovada pelos consumidores. no sistema convencional, o painel da lavadora é conjugado a cuba, o que traz a desvantagem da perda de espaço no interior da lavadora. o objeto desta patente foi projetado para que o painel fique acomodado de tal forma que permita o aumento da capacidade da cuba. além disto, tal disposição construtiva aumenta o volume da cuba dispensando o uso de tampas fixas nas lavadoras para abrigar o painel de comando, pois estas tampas fixas são peças caras. assim, a engenhosa disposição do painel de comando da lavadora, ao permitir maior capacidade de carga da cuba, faz com que, ao mesmo preço, lavadoras originalmente de menor capacidade de carga, possam competir no mercado dos modelos maiores, mantendo os preços dos modelos menores.

Abstract: Water-soluble hydroxypropyl-methyl cellulose is produced by treating soda cellulose having a weight ratio of air-dry cellulose to NaOH between 1:0.5 and 1:0.9 simultaneously with 0.02 to 0.15 part by weight of propylene oxide and at least 4 parts by weight of liquid methyl chloride per 1 part by weight of air-dry cellulose under pressure at temperatures from 40 DEG  to 100 DEG  C., and subsequently, after removal of the excess methyl chloride, the crude product is purified in a known manner, e.g. washed with water at about 85 DEG  to 95 DEG  C. to remove any sodium chloride and methanol formed, and centrifuged or filtered to remove excess water. The washed product may then be homogenized in an extrusion press from which it is extruded in the form of strands, dried and ground, e.g. in a hammer mill, to a grain size of 0.1 to 0.6 mm. The product may then be dried in a current of hot air to a water content of about 5 to 12%.  A small proportion of a wetting agent may be added to the purified product before the homogenizing step. "Air-dry" cellulose is defined as common cellulose having a water content of 4.5 to 6.5% by weight.

Abstract: 877,179. Weighing apparatus. DEMAG A. G. Jan 2, 1959 [Jan. 2, 1958], No. 268/59. Class 143 The loads fed to mine skips are metered by an arrangement comprising a measuring container at least one point on which is connected by movable suspension means to a framework attached to stationary timbering in a mineshaft, the suspension means incorporating a weighing device. The container 1 has at one end an inlet 4 at which it is fed from a hopper 5 and at the other end a closable outlet 2 from which a weighed load is discharged into a skip in the shaft 3. As shown, suspension means 6 are attached at each end of the container to a framework comprising two separate frames 8 each secured to fixed timbering. Horizontal forces generated during loading are absorbed by the members 7 whose lengths are variable by screw spindles to allow for adjustment should the frame members 8 be moved by rock displacements. In another form, not shown, the greater part of the length of the container is surrounded by a network of interconnected frame members, which framework is secured to fixed timbering, a suspension means 6 and a horizontal member 7 being attached between the framework and the container at each end thereof. Each suspension' means 6 comprises, as shown in Fig. 3, two identical members each universally jointed at its upper end 14 to a frame member 8 and at its lower end to a member 23 in which is an eye 24 from which the container is suspended. Each of the two members of the suspension means incorporates a load cell 18 which is compressively loaded by the relative movement of plates 13 and 17. Plate 13 is connected to a crosshead 11 attached to the lower universal joint and plate 17 is similarly connected to the upper universal joint, the connection between each plate and its joint being through opposite pairs of vertical plates 12 and 16. The plates 13 and 17 are guided for vertical movement by attaching them by central screws 21 to flexible diaphragms 19 and 20 respectively, the peripheries of these diaphragms being attached to the side walls 16 and to the crosshead I respectively.
