    • 447,831. Type-bar-making machines. MERGENTHALER LINOTYPE CO., 29, Ryerson Street, Brooklyn, and ACKERMAN, W., Towners, both in New York, U.S.A. Nov. 26, 1934, No. 33907. Addition to 365,289. [Class 100 (iii)] Trimming type-bars; moulds.-In the trimming-mechanism described in the parent Specification, in which an individual reciprocating knife is employed with each mould for trimming the back of the slug, the knife-slide is operated by means arranged to intercept it during the rotation of the mould-disc. This enables the guides of the knife-slide to be confined within the limits of the mould, so that a longer mould can be used for casting the long low slugs used in printing telephone books &c. The mould is formed of lower and upper parts B B , Fig. 12, the end walls being integral with the lower part, so that separate liners are not required. The mould is of greatly reduced depth, and its back is spaced from the front face of the mould disc C, Fig. 13, so as to leave a recess B , in which the knife-slide B can move. During the rotation of the mould from casting to ejecting position, a pin B on the knife-slide is arrested by a stop E, Fig. 1, which is projected into its path. The stop E slides in a bracket E mounted on the mould-disc slide, and is advanced towards the disc and retracted therefrom by levers and a cam E on the hub of the disc. The stop is also moved laterally to compensate for the varying distance of the pin B' from the centre of the mould-disc as the knife-slide traverses the mould. This is effected by additional cams, which impart a reciprocating movement to the bracket E . In order to return the knife-slide to normal position before ejection of the slug, an actuating-element F is projected towards the mould-disc and behind the pin E'. After the retraction of the stop B , the element F is given a speed considerably faster than that of the mould-disc, so as to carry the knife-slide before it. This is effected by a lever G, mounted on the mould-disc slide and linked to the element F. The lever G is operated against the tension of a spring G' by a lever G , an arm G of which is engaged by a cam G on the mould-disc. The pin-actuating element F is constrained to move in the same path as the pin B by a curved slot F in a bracket F secured to the mould-disc slide, and is moved towards and away from the disc by engagement with suitably formed grooves in the upper and lower faces of the slot F . Displacement of the slug in the mould during trimming is prevented by pins h , Fig. 12, which are projected into the mould-cavity during casting by a parallel-motion bar H operated by a cam. The two end pins are projected right across the mould, and produce notches in the ends of the slugs, to receive ribs on the trays or galleys in which the slugs are stacked.

    • A portable cooler has at least three separate storage compartments that comprise at least one ice-cold storage compartment; at least one dry moderately cold storage compartment; and at least one dry non-cold storage compartment. A temperature gradient construction enables the user to proficiently store food and non-food items of varying water sensitivities and temperature needs. Typically, a wet cooling medium is added to the ice-cold storage compartment. Discrete thermal conduction pathways extend from the ice-cold storage compartment into the moderately cold storage compartment, cooling the moderately cold storage compartment. The less cold compartment and the non-cold compartment are completely dry of water. Each of the compartments has its own lid enabling selective entry and thereby preventing temperature fluctuations and moister transfer when another compartment is accessed. The portable cooler has a plurality of foldable wheels on the base thereof to facilitate portability.
    • 便携式冷却器具有至少三个独立的存储隔间,其包括至少一个冰冷储藏室; 至少一个干燥中度冷藏室; 和至少一个干燥的非冷藏室。 温度梯度结构使用户能够精通食品和非食品的水分敏感性和温度变化。 通常,在冰冷的储藏室中加入湿式冷却介质。 离散热传导路径从冰冷储藏室延伸到中等冷藏室,冷却适度冷藏室。 较冷的隔间和非冷藏室是完全干燥的水。 每个隔间都有自己的盖子,可以选择性进入,从而防止温度波动和湿气传送。 便携式冷却器在其基部上具有多个可折叠轮,以便于便于携带。
