Filed: 1934-11-26
Abstract: 433,113. Cooling - towers. COEY, S. C., Glen Ridge, New Jersey, U.S.A. Nov. 26, 1934, No. 33989. [Class 29] In a cooling-tower, the liquid falls from a tray 33 in an annular curtain over baffles 39, and a fan 57 draws air inwardly between the lowest set of baffles which are open to the atmosphere and forces it out through the middle baffles of the tower, a casing 50 compelling the stream of air then to pass inwards through the highest group of baffles before leaving at the top of the tower. The air stream leaving the tower passes through stationary fan blades 86 which cause it to rotate and entrained water is thus centrifugally removed. An intermediate liquid distributing tray 22 and a bottom collecting tray 13 are provided. The trays 22 and 33 are divided into annular sections by dams 44 and 35. Liquid enters one portion of the trays and flows over the dam to the other half which it leaves by apertures in the tray bottom. The dams may have slots cut in them at intervals to allow passage of liquid at all points even if the horizontal positions of the trays are disturbed.

Abstract: 1498485 Manipulators HAGENUK 26 Aug 1975 [6 Sept 1974] 35163/75 Heading B8H A manipulator comprises work-handling elements of rotary (Fig. 1) and linear (Fig. 3) type, which can be connected together in series as shown in Fig. 7 (not shown). Each rotary element, Fig. 1, comprises a rotatable shaft 7 on which twin grippers 78a are mounted, rotation of the shaft 7 being effected by means of motors 3, 9 which respectively drive discs 1, 8 which are keyed at 30, 34 respectively to the shaft 7. The disc 1 comprises an auxiliary actuating mechanism and the disc 8 comprises a follower actuating mechanism, the former mechanism being operative to position stops or abutments which limit the travel of the follower mechanism to which the load-engaging grippers 78a are attached. On the disc 1 a gapped abutment 20 is located, in whose gap an abutment 19 of the disc 8 is disposed with clearance, as shown in Fig. 2 (not shown). The discs 1, 8 rotate simultaneously, and when the desired position of the grippers 78a is being approached the speed of motor 3 is reduced by the operation of a control programme associated with a control block 50, and stops at the required position, whereupon bellows-type braking cylinders 13 are caused to expand upwards and push the disc 1 against a brake ring 24. The speed of motor 9 is reduced accordingly due to a speed control member 4 to which the rotation of the motor 3 is transmitted, and when the abutment 19 (depending on the direction of rotation) engages one of the bearing surfaces (17, 18, Fig. 2) of the abutments 20 the motor 9 stops and thus shaft 7 ceases rotation. Each linear element, Fig. 3, comprises movable parallel columns 41, 42, an abutment 59 on the column 42 being located between abutment surfaces 17<SP>1</SP>, 18<SP>1</SP> formed in the column 41.

Abstract: 464,708. Spring forks. NORTON MOTORS, Ltd., and FRANKS, E. M. Dec. 19, 1935, No. 35175. [Class 136 (iii)] - In a spring fork for motorcycles, a compression spring is connected at its ends to abutments on the steering- head and fork by means of universal or pivoted joints of which the axes are set in some distance from the ends of the spring, whereby the spring is compressed and extended in a truly axial direction, and lateral distortion of the spring is avoided. The fork a, carried from the steering-head by pairs of upper and lower links c, d, is controlled by a coiled compression spring f, which is interposed between the head and fork with its end coils at each end engaged in a helical groove on the surface of a sleeve or cap g having a domed inner end forming a socket h to receive a part-spherical head k on a stud j. These parts are held in engagement by a sleeve l which is screwed into the cap g and is spherically shaped at its inner edge where it engages the head k. Lubrication of the joint is effected through an axial passage bored in the stud j and fitted with a nipple n. The upper stud j is rigidly secured in a lug p on the steering-head by a nut q, while the lower stud j is similarly secured in a lug r on the fork. The outer end of each cap g is formed with an annular groove to receive a ring or washer s, which is held in place by swaging over the end of the cap and forms a stop for the end coil of the spring. In a modification, in which the ends of the spring rock in one plane only, the cap engaged with the end coils of the spring is transversely slotted at its inner end to receive an eye on the inner end of an attachment stud over which the cap fits, the cap being pivotally connected to the stud by a pin passing through the cap and eye.
