Title: Cast metal heat exchanger and mould therefor
IPC: B22C9/26
Filed: 1976-05-14
Abstract: The cast-metal heat exchanger (1), which in particular serves as a central heating boiler and comprises a number of exchanger elements (2, 3, 4) arranged one behind another, through the cavities (5) of which heating medium flows and which have ribs (6) on the outside which are flowed around by the smoke gas, forms a one-piece casting which comprises all the exchanger elements and extends along the side walls and end walls extending over the entire length of the heat exchanger. For the method for manufacturing the heat exchanger, in which the exchanger elements are cast as a whole with side walls and end walls extending over the entire length of the heat exchanger, a casting mould is used, which has two end cores, a number of identical intermediate cores as well as cores which form the cavities for the heating medium circulation, which cores are all centred by core eyes engaging in fitting cavities and are arranged with their circumferential edges clamped in relation to one another. This heat exchanger has the advantages that the work which was previously necessary for the assembly of individual members is eliminated and that, by virtue of the one-piece design, no leaks occur. <IMAGE>

Abstract: 1,057,843. Massaging appliances. J. ROMANOWSKI. May 19, 1964 [May 20, 1963], No. 19965/63. Heading A5R. A massaging appliance comprises a frame formed by members (10), (11), (12), 13 pads of foamed rubber 14 secured to the members and adapted to form a substantial airtight seal between the frame and the part of the body to be massaged and a flexible diaphragm 20 supported by the frame and spaced from the body to form an air cavity 21. A pulsating pressure variation is produced in cavity 21 by flexing the diaphragm 20 by a reciprocating rod 23 driven by an electric motor which is coupled to the rod by an eccentric coupling. The diaphragm may be provided with adjustable inlet compression valves 36, 37 for the introduction of warm air or oxygen and exhaust valve 45.

Title: Animal trap

Filed: 1923-08-10
Abstract: 223,349. Marks, E. C. R., (Snappy Manufacturing Co. of Canada, Ltd.). Aug. 10, 1923. Animal traps.--A break-back trap comprises a sheet metal base plate 10 having integral reinforcing side walls 11 which carry the pivot 12 for the spring operated break-back frame 13 having two projecting arms 15 engaged by a link 20 which is pivoted at 21 to a plate 18 which is depressed by foot to raise the break-back frame to its set position. This plate 18 is of sheet metal and is pivoted at 19 to the base 10. When the plate 18 is depressed the link 20 is also depressed by means of the plate engaging a part 23 of the link, and the pivotal connection between the link 20 and the arms 15 being a sliding one the arm 13 is raised from the sprung position of Fig. 2 to the set position of Fig. 3 in which the angle between the link 20 and arm 13 is nearly a right angle, so that the component of the force of the spring 16 acting along the link 20 is very small. The point 21, in the set position, is above a line joining the pivot 19 and the connection of the link 20 and' arm 15 so that there is a small force tending to raise the plate 18 which is held depressed, however, by a tongue on a counter-weighted bait-lever 24. When the baitlever is disturbed and the plate 18 released this plate is slowly raised by the small force along the link 20 until this link is appreciably out of the dead-centre position when the force greatly increases and the frame 13 strikes sharply downwards. Fig. 6 shows a modified bait-lever which, instead of being counter-weighted, has an arm 29 protruding through a slot 31 in the footplate 32 so that as the foot presses the plate 32 downwards it also positively rotates the bait-lever 29, 30 counterclockwise to lock the plate 32.
