Title: Regenerative heat exchanger
IPC: F28D17/00
Filed: 1971-10-19
Abstract: 1386609 Thermal regenerators SVENSKA ROTOR MASKINER AB 18 Oct 1972 [19 Oct 1971] 48586/71 Heading F4K A system comprising two or more rotary regenerative heat exchangers is arranged so that one at least of the heat exchangers can be shut down for cleaning or repair by redirecting all the hot and cool fluid flows to the remaining heat exchanger(s). In the system shown there are two rotary regenerators I, II interconnected by ducting with the heating gas inlet 10 and outlet 12 and with the inlet 14 and outlet 16 for air being heated. Valves in the ducting are operated to direct all the heating gas and air through one or other of the regenerators (regenerator I for the valve setting shown in Fig. 1) whilst isolating the other regenerator. For a period immediately following a changeover, residual heat in the shut-down regenerator may be utilized to preheat the air passing to the freshly-used regenerator. This brings the latter quickly up to operating temperature and at the same time quickly cools off the shut-down regenerator. The preheating is effected utilizing the cross-ducts 26, 28 as indicated by the valve settings in Fig. 4, where the regenerator I has just been brought into service.

Title: Doll weeping mechanism and doll
IPC: A63H3/24
Filed: 1972-10-25
Abstract: 1395589 Weeping dolls IDEAL TOY CORP 25 Oct 1972 [22 Dec 1971] 49187/72 Heading A6S [Also in Division F1] A doll which weeps when placed in a generally horizontal position has a flexible reservoir 47 for water introduced through its mouth 30 and a weight 70 which compresses the reservoir to force the water out through the corners of its eyes when the doll is laid upon its back. In the vertical position shown, a simulated feeding bottle 52 'has had the tip 55 of its nipple introduced through the doll's mouth to push back a valve 34 against the bias of its spring 36, closing a valve port 42 and allowing water to flow through a chamber 20a to fill the flexible reservoir 47. When the feeding bottle 52 is withdrawn, the spring 36 closes the valve 34 against a seat 32 to prevent water running out of the doll's mouth. At the same time, the valve 34 opens the port 42. If the doll is now laid flat on its back, Fig 3 (not shown), the weight 70 squeezes the flexible reservoir 47 and forces water through the open port 42 to a chamber 20b, 20c a sponge 67 acting as a flow restrictor, and two parallel bushings 63, one leading to each eye 64. Small plugs 69 in the bushings 63 further restrict the flow of water. Each eye 64 forms a chamber C connected through small holes (73) Fig 4 (not shown) at each side to a socket. chamber 72 receiving the eye. The front of each socket chamber 72 is oval in shape, leaving a very small hole at each outer corner (75), Fig 1 (not shown), through which drops of water emerge as simulated tears. Alternatively, each eye may have a small central hole for drops to emerge. If the doll is instead placed on its stomach weeping will still occur, water flowing directly out of the eyes 64 which are now below the level of the reservoir 47. In either case, restoring the doll to the vertical position shown stops weeping, the weight 70 no longer squeezing the flexible reservoir 47. A rubber band 72 around the weight 70 silences movement of the latter within the doll.

By tilting the unit forwards (Fig. 5) the cable 98 can be buried close to an obstruction 97 and by tilting the unit backwards, Fig. 4 (not shown), the cable can be caused to exit from the ground close to an obstruction e.g. a wall (167). An engine 125 is provided on the unit to drive the wheels 9, 10 through a gear box including a reverse and also to drive, via crank devices, a central block (25), (Fig 13, not shown), through which the blade (27) slidable panes. The block is also attached by links 29 to the top of the blade by a shaft 31 and thus the desired elliptical motion 54 is imparted to the point 112 of the digging blade. A rachet mechanism 58, 67, 73, 74 is provided adjacent the top of the blade which, in one position of adjustment, causes the vertical reciprocation of the blade to raise the blade and in a second position to lower the blade. A cable drum 117 may be provided on the unit, the cable 98 being fed down a tube 99 positioned in the lower part of the blade; alternatively the cable may be positioned on the ground and be fed by hand into the unit. In Fig. 15 (not shown), crank block (25) is positioned above links 44 so that the elliptical path of the blade point has its axis vertical. A ram e.g. hydraulic may be pivoted on the side of the unit with a foot which can be positioned at the front or rear of the unit, so that the unit may be tilted by the ram in either direction.
