Title: Radar apparatus
Inventor: WILLIAMS PHILIP DAVID LANE
IPC: G01S13/24
Filed: 1983-01-31
Abstract: Radar apparatus functions by transmitting (10, 12, 13) cyclically repeated sequences of pulses having mutually different frequencies, received (13) echo pulses being separated (12) into respective reception channels (TR1TRN) in dependence upon their frequencies, and there mixed (18 to 21) with local oscillator signals (26) to give signals at a common intermediate frequency, which signals are delayed ( tau 1- tau N) such that delayed signals corresponding to echoes at different frequencies from a single target coincide in time. The delayed signals then provide range information to a maximum range corresponding to the maximum unambiguous range for radar apparatus with a pulse repetition frequency equal to the rate of succession of the sequences of pulses. <IMAGE>

Title: Oxygen therapy method and apparatus
Inventor: CHAUDHURI ARUP R
IPC: A61M16/06
Filed: 1983-09-22
Abstract: A rebreathing apparatus is designed to minimize the amount of oxygen required in oxygen therapy to maintain a given or desired oxygen level in the blood and includes a changeable volume chamber (15, 25, 35, 45, 55) having a maximum volume less than the maximum volume of the respiratory tract of a user and to which a continuous source of oxygen is supplied so that the initial gas exhaled on exhalation is directed into the changeable volume chamber and so that the remainder of the exhaled gas is vented to the ambient. Oxygen is supplied to the apparatus via inlets (13, 23, 33, 43, 56) to increase the oxygen content of the retained gas as some of it is displaced from the apparatus so as to create a bolus of oxygen enriched gas. On inhalation this quantity is initially taken into the respiratory tract and the latter is then filled concurrently with ambient air and gas from the apparatus. This sequence is followed as long as the therapy is administered.

Title: Food product and method of and apparatus for making the same
Inventor: BENSTEAD ALAN J
IPC: A23L13/70
Filed: 1985-07-04
Abstract: A food product comprises a core of compacted meat and an outer layer intended to simulate the rind of a traditional meat joint. The outer layer comprises a mixture of comminuted natural meat rind, comminuted meat and salt whereby salt soluble protein in the mixture is available in the mixture to act as a binder. The product may be made by treating pieces of meat to release salt soluble protein therefrom, forcing the meat into a tubular casing to provide a compact bar encased in said casing and freezing the bar and casing. The casing is then stripped from the bar whilst keeping the bar frozen, and the frozen bar is passed longitudinally through a coating device which applies to the exterior of the bar, in an initially plastic or flowable condition, a rind coating which freezes on contact with the bar. Apparatus for use in making the product includes a coater having a passage therethrough for the frozen core, said passage including an upstream part adapted to receive the core as a close sliding fit and a coaxial downstream part of a greater diameter, and means for forcing into the annular-section space defined between a frozen core extended through said downstream part and the wall of the downstream passage part the material to form the outer layer.

Title: Rotating coiled tube contactor
Inventor: SIMPSON JAMES ROXBY
IPC: C02F3/08
Filed: 1987-02-22
Abstract: A device for bringing microorganisms into contact with liquids as required, for example, in the treatment of sewage, comprises a hollow main shaft 1 into which the inner ends 2 of coiled tubes 3 are inserted and fixed. Each tube is coiled in increasing diameters at right angles around the shaft. The shaft is placed in a tank 6 partially immersing the tubes such that when the shaft rotates the open end of each tube, into which liquid enters, alternatively passes through the liquid 7 and then the surrounding atmosphere. Liquid picked up during previous revolutions rotates through the tubes and eventually discharges into and through the hollow main shaft to a receiving vessel. In this way, discrete volumes of liquid pass sequentially through the tubes and are brought in contact with the microorganisms on the inner surfaces of the tubes. <IMAGE>
