Abstract: 171,746. Macdonald, D. Aug. 12, 1920. Radiators, motorcar and like. - A rotary radiator for cooling liquids, particularly applicable to cooling the circulating water of an internal - combustion engine, comprises a fan-wheel W, Fig. 1, provided with a number of pairs of arms I, O fitted into the hub H of the fan-wheel and flattened out at their outer ends and communicating with one another through a water-channel R forming the rim of the fan-wheel. The water channel is preferably continuous except at one point and the arms I, O project into it so as to divide it into sections corresponding to each pair of arms, but leave a small space for intercommunication between the sections. The hub H, which is divided by a partition M, is mounted on ball bearings on a twopart hollow shaft S attached at its forward end to a circulating-pipe P communicating with the upper part of the water-jacket J and at its tail end to a pipe connection X secured to the lower part of the water-jacket. The water in circulation flows from the water-jacket through the pipe P to the forward part of the shaft S, then outward through the arm I into the arm O and through the other part of the shaft S to the water-jacket; the arms I, O are arranged tangentially to the hub H in opposite directions, and the arm I is adapted to carry a greater quantity of water than the corresponding arm O so as to ensure a continuous circulation. The rim R, which is preferably provided with a protective rim E and felt liner FL, Fig. 11, is secured to the hub H by means of spokes adapted to pass through eyelets Y formed in the rim. In the form shown in Fig. 8, the shaft S is made in one piece and two annular water spaces are formed in the hub H, and these are provided with vanes or blades D attached to each side of the partition M of the hub for the purpose of directing the flow into and out of the arms I, O. A stop valve B provided in the upper pipe P is adapted to be closed to arrest the circulation while starting the engine in cold weather. A driving-pulley V is fitted to the hub of the fan wheel and is rotated by a belt or chain from the engine.

Classes 44 and 89 (1). An attachment pin for fixing a first member 10 to a second member 11 is made of a resilient material in one piece and comprises a head 12 and a shank portion 14, presenting longitudinal ribs 15, the roots of which are interconnected along the length of the shank portion and which taper towards the end of the shank portion remote from the head, the shank portion having a neck 16 adjacent the head and the ribs having shoulder faces 17 which extend outwardly at the base of the neck beyond the periphery of the neck. In the construction shown, the member 10 is a trim moulding and the member 11 is the body panel of a motor vehicle. The two members are gripped between the underface of the head and the shoulder faces 17, the pin being engaged with the member 11 by passing its shank portion through an aperture 24 in the member 11. The connection between the ribs 15 and the neck 16 is undercut to promote flexibility of the ribs and the neck can be a sufficiently tight fit in the aperture 24 to make a water-tight connection. The head has a recess 21 which provides an annular rim and this resiliently engages within the channel of the trim moulding to locate the trim moulding transversely on the head. As shown, the shank portion has four ribs which together with a portion 18 which join them together are arranged in H formation but in a modification the ribs can either be arranged radially or adjacent pairs can be at right-angles, with the ribs offset from the long axis of the pin by an amount equal to that thickness, the edges being chamfered or radiused to permit easier entry into the aperture. The pin can be used for connecting two panels together in which case the head is flat and instead of faces 17 which are substantially at right-angles to the axis of the shank portion the faces are obliquely arranged so that the pin can easily be withdrawn from the aperture. The head can be in the form of a two jaw clip for gripping pipes or cables.

Title: Improvements in or relating to twin variable-delivery pump units
IPC: F04B1/08
Filed: 1968-05-23
Abstract: 1,212,609. Reciprocating pumps; hydraulic circuits. LINDE A.G. May 23, 1968 [ May 24, 1967], No.24557/68. Heading F1A. In an arrangement in which two pumps 5, 6 deliver pressure to their respective loads, e. g. the ram system and traction motor of a mechanical shovel, along respective lines 21, 25 and through respective valves 28, 29, delivery is automatically controlled by a device in which a stepped piston 8, acted on by a spring 12, bears against a pushrod 14 acted on by a second spring 17, and a second piston 18, passing through the stepped piston 8, is integral with or connected to the pushrod 14. Working spaces 9, 10 and 19 are defined by the stepped piston 8 and the piston 18 respectively. The delivery line 21 is connected to the working space 10 and the delivery line 25 is connected to working spaces 9 or 19 according to the setting of a valve 23. Stroke adjusters 7, 16 of the pumps 5, 6 are operated by the members 18, 14 respectively. When the working spaces 9 and 10 are pressurized the piston 8 and the pushrod 14 move together so that delivery of both pumps is equally regulated. Pressurization of the working space 19, however, temporarily moves the pushrod 14 away from the stepped piston 18 and causes independent regulation of the pumps as described in the Specification. A valve 30 is connected between the two delivery lines 21, 25 so that both pumps may, if so required, deliver to the same load. The valve 23 may be manually positioned or may be adjusted to change setting at a predetermined pressure. One pedal may operate the valves 29, 30 and 23 in a described frequency.

Abstract: 422,622. Vacuum cleaners. HOOVER, Ltd., Perivale, Greenford, Middlesex.-(Hoover Co. ; North Canton, Ohio, U.S.A.) Aug. 27, 1934, No. 24690. [Class 8 (i)] In suction cleaners which are moved over the floor and are adapted, by breaking communication between the suction mouth and the fan, and making communication between the fan and a flexible hose, to clean curtains &c., the act of putting the dusting tool into condition for use is caused to necessitate or effect the raising of the nozzle and agitator from the floor. Fig. 2 shows a cleaner in which a cover K is removed and a converter inserted in the aperture uncovered, closing communication between the fan eye and the nozzle itself and communicating with the fan eye. This act pushes aside a wedge L and through a bar L<1>, lever L<2>, and arm H<1> rocks a cranked spindle H carrying the front wheels and raises the nozzle. A screwed rod embracing the cranked shaft enables the height to be adjusted. In modifications, a pivoted cover pushed aside by the converter actuates the nozzle-raising means. In a further modification, the wheels are raised manually causing the arm H' to be moved from a normal position wherein it obstructs a lug on the converter, preventing insertion of the converter. When a permanently attached converter is provided, as described in Specification 422,609, an arm on the rotary converter operates the cranked spindle carrying the wheels. In a further modification, the handle is connected to the wheel-raising means, and lifts the wheels when it is pushed into vertical position. The height of the rear wheels may be adjusted manually. Electrical means under the control of contacts may replace mechanical nozzleraising devices.
