Abstract: 1332478 Automatic cartridge changing/playing J A BRITZ 11 Nov 1970 [13 April 1970] 53671/70 Heading G5R An automatic tape cartridge changer-player has a step driven rotary drum store, and cartridges therefrom may be played back selectively and sequentially. The step drive for the drum 26 comprises a solenoid actuated ratchet wheel and pawl system 51, as in Figs. 1, 3, (Fig. 3, not shown), the solenoid 65 being arranged in a make and break circuit (Fig. 10, not shown) to obtain the step pulses. When a cartridge 45 has been rotated to a position 45A, it may be transferred to a holder 87 at a position 45B by a rod 119 in a motorized transfer system 111, Figs. 1, 2 (Fig. 2, not shown). The holder. 87 is then rocked to a position 45C (Fig. 4), to engage the cartridge with a tape deck 72, an activating pin 94 on an arm 97 (Fig. 1) being moved by a motor 108 via a shaft 106 and disc 105. The forward track of the tape is then played back by deck 72 and at the end of the tape a metal strip (205, Fig. 10) makes a contact (207, 208) to cause activation of the motor 108 to rock the holder 87 to a position 45D; a deck 73 then plays the reverse trunk. A tape strip (213) then causes the motor 108 to rock the holder back to position 45B whereupon the transfer system 111 is activated to return the cartridge to the drum. For cartridge selection purposes, a disc 141 has a series of spaced pins 145 which may be pressed or not pressed selectively and manually, or may be pressed automatically but non-selectively, (by a lever 151 as in Fig. 7, not shown), so that contacts 148, 149 of a switch 146 may or may not be made. :The transfer system 111 is then operated, or not operated, accordingly. The tape deck motors 75, 81 (Fig. 4) are controlled according to the angular positions of cams 131-134 (Fig. 1) on the shaft 106.

Abstract: 1,114,049. Combined air and water heating apparatus. A. A. STRUIJK. 22 Dec., 1965, No. 54338/65. Heading F4S. In an arrangement using a convector airheating stove 9 to heat a conventional back boiler 22 in a fireplace opening, the convector stove is of the type which heats the room by both radiation and convection. The stove has two flue outlet branches 13, 16. Gases flowing out of the branch 13 pass direct to the chimney 21 and gases flowing out of the branch 16 flow over the back boiler 22; and the gases may be apportioned between the two branches either manually or by a thermostat in the hot water supply. In the apparatus shown, the fireplace opening is closed by a plate 29 through which the flue gas ducts 13 and 16 extend. Baffles 25, 26, 28 direct the gases from the branch 16 over the boiler 22. The convector stove (Fig. 1, not shown) comprises an outer casing having an inlet grille (15) for unheated room air and an outlet grille (14) for heated air. The combustion unit comprises an oil or gas fired burner (12) discharging into an upright flue containing an air heating heat-exchanger (11). The flue pipe 16 is upstream of the air heater whereby only the hottest gases may flow to the boiler. The flue pipe 13 is downstream of the heat exchanger and discharges direct to the chimney. Apportioning of the flue gases is by means of a valve or valves (17, 18) in the pipes 13, 16 or a three-way valve at the junction of the pipe 16 with the upright flue pipe (12).
