Title: Equipment for location of lost persons - precision guidance to lost person achieved by manual gain control
IPC: G01S1/02
Filed: 1973-05-18
Abstract: Detector and transmitter are for localisation of a lost person or object, transmitter being carried by person or object and detector being carried by searcher. The transmitter comprises either a ferromagnetic or electromagnetic screened framed aerial, a quartz oscillator, and electrical energy source, and can include a modulator. The frequency range of the transmitter is from several megaHertz to serveral dozen megaHertz. The detector has a directional frame aerial (5) an omnidirectional aerial (6), an aerial switching unit (7) feeding a high frequency amplifying stage (8) driving a mixer (9) which receives energy from a local oscillator (10). The output of the mixer (9) drives a medium frequency unit (11) whose gain is regulated by a unit (12). The output of the medium frequency unit (11) drives the balanced modulator (13) which received the local oscillator (14). Field level measurement is obtained at this point by a galvanometer (15). The output of the modulator (13) drives a numerical divider (16) whose output drives an AF amplifier (17) feeding a loudspeaker (18). An electrical energy source (19) completes the system.

Title: Copolymer plasticisers for PVC prodn - using addn of epoxide and lactone to active H-contng initiator
IPC: C08G63/08
Filed: 1973-08-10
Abstract: A copolymer is prepd by simultaneously adding an epoxide and a lactone to an initiator contg. an active H which can open the lactone or epoxy ring in the presence of an acid catalyst, the speed of addn being such that excessive accumulation of lactone and epoxide in the reaction system is prevented. Formation of block copolymers is obviated and the copolymer formed has a lower m.pt. than similar prods. prepd. by other methods. Liquid copolymers can therefore be produced for use as plasticisers for PVC and in polymethanes prodn.

Title: Air-conditioning liq. cooling system - uses refrigerant circulation by gravity in tubes through hot and cold ducts
IPC: F24F12/00
Filed: 1974-10-23
Abstract: The simple cooling system suitable for air-conditioning, has a set of finned tubes (1a, 1b) filled with a liquid refrigerant and passing through an inlet duct (3a, 3b) and an outlet duct (2a, 2b) underneath, forming inlet and outlet for air to and from a room. Air heated in the room passes through the outlet duct and vapourises the liquid inside the tubes, which rises and cools the air entering through the inlet duct, and falls by gravity as it absorbs heat and becomes warm again, giving a continuous circulation. In another design, sloping heat exchanger tubes are attached to a hollow disc rotating about a horizontal axis. the refrigerant liquid is retained in the hollow disc by centrifugal force, where, as it warms up, it vapourises, and in a further stage of each cycle, cools down and passes through the tubes.
