Patent GB-173194-A (GB)
Abstract: 173,194. Haddan, A. J. H., (National Cash Register Co.). Sept. 16, 1920. Cash registers; cash drawer or till mechanism. -In a machine in which a crank handle or lever is operated to restore a totalizer to zero for total printing, independently of the main operation of the machine, the crank-handle communicates its drive through a spring coupling-device. The invention is described as applied to the key-set, key-operated machine, set out in Specification 142,436. The handle 85, Fig. 1, is fast with a sleeve 90 which is loose on a stub shaft 86 and is recessed at 91 to receive a lug 92 on a loose disc 93 to which the casing 95 is secured. The gear wheel 87 loose on the shaft 86 is in one with a sleeve 96 ending in a flange 97 to which the disc 98 is fastened. Between a flange 100 on the casing 95 and a lip 99 on the disc 98 is located a compressed spring 101 which normally holds the lip 99 in contact with a lip 102 on the casing. On rotating the handle clockwise, Fig. 2, the spring drives the disc 98 and gear 87, a too quick motion of the handle being taken up by further compression of the spring. The compression of the spring is limited by a pin 103 carried by the disc 93 working in an opening between shoulders 104, 105 on the disc 97. The gear 87. meshes with a gear 88, Fig. 3, on a shaft 89 which moves one revolution counterclockwise for two clockwise revolutions of the handle. Plates 109, 113 are fixed to the wheel 88 and a roller 110 on the former normally lies in a notch 119 in a pivoted spring-pulley-arm 118. A yoke 112 pivoted at 116 has legs 111, 115 which co-operate with the roller 110 and a notch 114 in the plate 113 to arrest the wheel 88 at the end of a complete revolution. The yoke has a hooked arm which is rocked upwards to engage the lip 102 and arrest the handle 85. The rocking of. the yoke 112 releases the drawer latch through a link 131 and two arms 133, 135, one fixed and the other loose on a shaft 134, engagement between the arms being by way of a pin and slot. The shaft 134 carries at the other end the drawer latch, the pin and slot allowing the latch to lift without affecting the yoke 112 when the drawer is pushed in. A spring acts on a pivoted arm which bears on a cam on the shaft 89 to equalize the turning- effort on the shaft. Specification 173,042 also is referred to.

Abstract: 573,787. Soap. SHARPLES CORPORATION. Dec. 5, 1942, No. 17332. Convention date, Nov. 4, 1941. [Class 91] In the continuous method of making soap by the procedure described in Specifications 549,386 and 549,387 wherein the saponification is effected in a plurality of stages in each of which the fat and saponifying agent are intensively agitated together in a mixing apparatus, the soap being grained by addition of a salting out agent, followed by separation of the soap from the aqueous reagent phase in a centrifugal separation, and the soap being finally fitted by mixing with water to give the neat soap and nigre after centrifugation, the nigre is returned to one of the saponification stages of the method. The nigre emulsifies the saponifying agent with the fat; it may be returned just after the saponification stage with the single advantage of recovering its soap content. In the plant shown, comprising two saponification stages, and consisting of mixers 12, 15 and. 21 each followed by centrifugal separators 13, 16 and 18 with the feed and connecting lines as shown, the process is operated as stated above and as described in detail in the Specifications quoted as far as the centrifugal 18 from which the neat soap is obtained separated from the nigre. The latter is then returned at points 19, 20 or 22. In a modification of the process, a source of acid is added to the soap-containing mixture being fitted prior to entering the mixer 21 for the purpose of neutralizing free alkali and the centrifugal 18 is replaced by a centrifugal provided with outlets extending from the inner circumferential wall of its rotor for the discharge of separated dirt. In a further modification of the process, the nigre obtained from the centrifugal 18 or the modified centrifugal above is subjected to a separate centrifugal clarifying step with addition of a source of acid to neutralize free alkali as described in Specification 559,076 before being returned to the saponification cycle.
