Filed: 1974-10-23
Abstract: 1488671 Refrigeration UNIVERSITY OF GUYANA and J C V CHINNAPPA 24 Oct 1974 [4 June 1974] 24739/74 Headings F4H and F4U A cooling apparatus comprises a first system through which a water-ammonia solution is circulated and which includes a solar heat collector 7, and a second system through which a water-ammonia solution is circulated, the latter solution being enriched by ammonia vapour from the first system and then boiled to produce a cooling effect, the resultant ammonia vapour being passed to the first system. As shown, the first system comprises an absorber 1, a pump 3, a heat exchanger 5, the solar collector 7, a boiler 9, and a solution storage vessel. Ammonia vapour from the boiler 9 is cooled in a condenser 28 and passes through either valve 31 or valve 41 controlled by an insolation sensor or by a temperature sensor at the inlet of boiler 9. When the valve 41 is open, the ammonia vapour passes to a resorber 22 in a system comprising a desorber 16 which provides a cooling effect for air conditioning. When the valve 41 is closed and the valve 31 is open, the vapour passes to a condenser 33 and thence to a refrigerant storage vessel 35, from which one stream passes through an expansion valve 37 to an air conditioning evaporator 39 and the resorber 22, thereby producing a cooling effect at both the desorber 16 and the evaporator 39. A second stream passes from the vessel 35 through an expansion valve 45 to an evaporator 47 for food preservation. Ammonia vapour from the desorber 16 and evaporator 47 passes to the absorber 1.

Title: Improvements relating to radio receivers and to apparatus for use therein or for analogous purposes
IPC: H03J7/16
Filed: 1934-08-31
Abstract: 443,640. Wireless receiving-apparatus. COLE, Ltd., E. K., Priory Crescent, Southendon-Sea, and BRADFIELD, G., 161, Hainault Avenue, Westcliff-on-Sea. Aug. 31, 1934, No. 25058. [Class 40 (v)] In a radio-receiver of the kind having manual tuning con trol and automatic means for ensuring final accuracy of tun ing, a step by step movement is auto matically imparte( to the tuning element which movement is arrested when the receiver is in tune with the signal. In the arrangement shown in Fig. 1, a spur wheel A carrying a spring-loaded paw B is rigidly mounted on the shaft M of the tuning element. A ratchet wheel N is rotatably mounted on shaft M and has a flange over which passes a cord L kept in tension by spring H, the cord being attached to the armature O of an electromagnet P. An escapement D, pivoted at E, carries a weight F, and a second electromagnet K has an armature G with two stops J preventing movement of the escapement D when the magnet is de-energized. When the receiver is within a predetermined degree off-tune, electromagnets P and K are energized by a manually operated switch ; the ratchet H is rotated anticlockwise by cord L. The energizing circuit of P is then broken and the ratchet N, spur wheel A and tuning element of the receiver are rotated in a clockwise direction by the action of spring H. Rotation of A is permitted by oscillation of escapement D and weight F until the holding current of electromagnet K ceases, which is when the receiver is in tune. The armature G then falls, thus preventing movement of weight F and also of spur wheel A. The circuit arrangement shown in Fig. 2, shows the output stage 4 of a receiver coupled to a reproducer 5 through transformer 12 in one position of a switch contact 11<1> and through an impulse rectifier 6 to one energizing coil 7 of magnet K, Fig. 1, in the other position. The energizing coil of magnet P, Fig. 1, is fed from the high tension supply through resistance R and switch contacts 1<1>, 21, and the second energizing coil 11 of magnet K is fed from the same source through resistances 8, 10 and contacts 31, 4<1> with a shunt condenser 9 as shown. All the contacts are arranged for operation by a single switch button 13, Fig. 3, so that in one position contacts 11, 2<1> ; 3<1>, 4<1>; 101, 11<1>; 15<1>, 16<1> are closed, energizing the two magnets as described previously. The automatic tuning then follows and the switch contacts are returned to their initial position. Contacts 31, 4<1> may be replaced by a spring device operated by knob 13 to throw arm G, Fig. 1, out of engagement with weight arm EF, Fig. 4 (not shown). Specification 443,363 is referred to.
