Abstract: 600,592. Lubricating bearings. ROULEMENTS A BILLES MINIATURES SOC. ANON. Nov. 19, 1945, No. 31080. Convention date, Nov. 18, 1944. [Classes 12 (i) and 12 (iii)] A ball, roller, or plain, bearing is lubricated from a capillary device without a wick, such as a pack of very slightly spaced discs, holding a supply of oil and a complete circuit of capillary conduits permits a circulation of oil through the bearing. The bearing can therefore be disposed in any position. A light-duty ball bearing, Fig. 1, adapted to take end thrust, comprises an outer race 1 of cup form, held in an outer casing 2 and serving to retain in position in such outer casing, by means of a cap piece 3, having a cylindrical skirt with longitudinal slits 15 in such skirt, a pack of capillary discs 4 which are very slightly spaced by means of protuberances 17 thereon. The balls 11, spaced by a cage 10, run on a tapered end of the spindle 7 which at its cylindrical portion has a collar with flange 6 extending radially to the ends of the outer race 1 and of the skirt of the cap piece 3. A fixed stub shaft 5 with small grooves 9 thereon extends through the capillary discs 4 to direct the capillary flow on to the ball cage 10 whence the oil passes through the bearing to the capillary passage way 14 formed - by the flanged collar 6 and thence through the capillary slits 15 of the skirt on the cap piece 3 to return to the passageways 8 between the capillary discs 4. Fig. 11 shows a grinding spindle 53 supported in a casing 56 by two ball bearings, the outer races 46, 47 of which have radial capillary ducts 48, 49, leading to capillary grooves 50, 51, broached on the interor of the casing 56 to give, through capillary slits 42, 43, in an inner sleeve 41, communication with capillary slits 44, 45, in inwardly flaring end rings on such sleeve 41 and with an oil reservoir space formed by a narrow biconical space 40 between such sleeve 41 and the casing 56. For the top bearing, the oil circulation is radially through the bearing to the duct 48 and through the groove 50, slit 42 in the sleeve 41, slit 44 in the flared end ring, and so back to the bearing. The oil circulation is similar for the bottom bearing. Fig. 6 shows a jewel bearing with the jewel 19 having on its outer surface capillary grooves 25 of decreasing depth through which the oil is returned to the reservoir discs 22 under the centrifugal action of a collar 23 on the shaft.

Title: Improvements in processes for improving the crease-resisting properties of textile materials
IPC: D06M15/423
Filed: 1947-11-27
Abstract: The process of the parent Specification for rendering textile materials resistant to creasing is applied to the treatment of materials composed wholly or partially of bast fibres such as flax, linen, or hemp, and is further modified in that the materials are subjected to a thorough swelling and shrinking treatment, and then, after being brought to a dry or substantially dry condition, are subjected to impregnation with the partial condensate of urea or thiourea and formaldehyde or other aldehyde buffered to a constant pH value of 4-6.  After the shrinking treatment the materials may be stretched before impregnation with the synthetic resin preparation. In an example, linen fabric is treated with caustic soda solution while free from tension so that it swells and shrinks.  It may then be soured, washed and dried, or it may be first stretched to dimensions which are still less than the original dimensions.  The dried fabric is then impregnated with a partial condensate of urea and formaldehyde in the presence of a buffering substance so that a pH of 4-6 is maintained during impregnation, drying and baking.  It is finally subjected to a mercerizing treatment.  Specifications 304,900, [Class 15 (ii)], and 437,361 also are referred to.

[Class 78 (iii)] The load carrier 11 of a lift truck slides up and down a vertical wheeled column 16 under the action of hydraulic mechanism mounted on the carrier and operating through a rocker 83 pivoted at 85 to the carrier and fulcrummed on the column. In the construction shown, the carrier 11 is mounted on the column 16 by a slidable sleeve 17 connected to it by side plates 18 and the pivot 85 of the rocker 83 is on upward extensions of side walls 58 of an enclosure, located between the side plates 18, for the hydraulic mechanism. The column 16 on its wheels 12 is at the front end of the truck, and forms a steering unit with a draught handle 19. The rear of the truck is supported by wheels 13 which are lowered relatively to the carrier 11 (which forms the body of the truck) as the latter is raised, in order to maintain it level. For this purpose the wheels 13 are carried by links 32 pivoted at 33 to the carrier, and connected through links 36, bell-cranks 96 and vertical links 94 with a cross-pin 78 extending through the rocker 83. As the latter is moved to raise the carrier up the column, the wheels 13 are lowered, and vice versa. Hydraulic lifting jacks.-The hydraulic mechanism is formed as a separable unit and comprises (Fig. 4) a ram 67 working in a cylinder 65 mounted, together with a pump 46 and a release valve unit 48, in an oil reservoir 51. A saddle 77 on top of the ram engages directly under the cross pin 78 on the rocker 83, whilst the pump plunger 121 bears under a lever 114 linked to an actuating pedal 105. The release valve comprises a spring-loaded ball 136 which is forced off its seat for lowering by depressing a plunger 141, the head 144 of which engages under a tappet 159 on an actuating lever operated by a second pedal. The lever is also operated .automatically when the carrier reaches its upper limit in order to prevent excessive pressure developing. The whole unit rests on a cross-shaft) 61 engaging a pivotal seating 63 in the base of the unit and extending between the side plates 58 of the carrier. Owing to the one-way connections of the pump, ram and release valve with their coacting elements, the whole unit can be removed through the open bottom of its compartment after withdrawing the cross-shaft 61.
