Title: Process of producing fried chicken under pressure
IPC: A23L5/10
Filed: 1962-12-20
Abstract: 960,990. Frying chicken under pressure. A. L. CUMMINGS. Dec 20, 1962 [Sept. 26, 1962], No. 48227/62. Heading A2E. [Also in Division A4] Fried chicken possessing optional moisture contents is produced by cutting raw chicken into serving pieces, coating the serving pieces with a moist layer of breading material of predetermined average thickness and moisture content, wholly immersing the coated serving pieces in a bath of liquefied cooking fat heated in a pressure cooking vessel to a temperature between 350‹ and 400‹F., hermetically closing the cooking vessel, reducing the temperature of the cooking fat rapidly to a cooking temperature of from 250‹ to 275‹F. in a time period of the order of two minutes while the pressure in the cooking vessel rapidly builds up towards a cooking pressure of approximately 15 lbs. per sq. inch above atmospheric pressure as a result of the conversion to steam of excess moisture in the layer of breading material, and cooking the pieces in the fat for approximately eight minutes at the cooking temperature and pressure referred to, the cooking pressure being at least sufficiently close to the vapour pressure of water at the cooking temperature to prevent boiling away of moisture from the pieces or the breading material. Compressed air may be introduced into the pressure cooking vessel if for any reason the temperature and pressure should fail to be lowered to the desired values in two minutes. The fried pieces may be stored for several hours in a warming oven held at a temperature of approximately 160‹F. without appreciable loss of desired flavour, texture or appearance. In an example chicken pieces were prepared for frying by cutting up two chickens each weighing from 2“ to 2¢ lbs. into from 16 to 20 serving pieces; the pieces were immersed in a dip made of skimmed or reconstituted skimmed milk and whole eggs (appriximately eight pieces per U.S. gallon of milk) and then rolled in flour to which salt, spices and other seasoning ingredients had been added. The prepared pieces were fried in seven to eight quarts of cooking fat. Apparatus may consist of a pressure cooker 14 mounted on a gas heated grill 13. The pressure cooker consists of a receptacle 15 and a cover 17 having a flange 17<SP>1</SP> superposed over an inwardly extending flange 18 of the receptacle; between the flanges 17<SP>1</SP> and 18 there is interposed a gasket 19. A pressure gauge 21, pressure controller 22 and an air line 26 are fitted in the cover.

Title: Digital device for detecting the presence of an nrz message

Filed: 1975-11-25
Abstract: 1499580 Data transmission; automatic phase control COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 25 Nov 1975 [25 Nov 1974] 48345/75 Headings H3A and H4P A device for detecting the presence of a binary NRZ message signal, even in the presence of considerable noise, comprises a transition detector 2 which generates a pulse for each change in binary polarity of an input signal applied to a terminal 1; a phase comparator 9 which receives the said pulse together with pulses from the output 8 of a local clock 3 and which compares the phases of the two sets of pulses to produce control pulses which are used to advance or delay respectively the phase of the clock 3 so that the latter tends to be phase locked with the polarity change pulses, the "advance" pulses and the "delay" pulses being applied respectively, by way of a switch 13, to terminals 4 and 5 of a counter-divider 7 whereby the phase of the clock is adjusted; an integrator assembly 17; and a terminal 16 to which an input can be applied to cause a fixed and sudden phase shift in the output of the clock 3, the arrangement being such that the integrator 17 receives the respective "advance" and "delay" pulses for a fixed time after the application of such a phase shift and sends out a signal when the number of pulses of one set, e.g. the "advance" pulses, reaches a given threshold and the number of pulses of the other set, e.g. the "delay" pulses, does not exceed a second threshold which numbers are, as the Specification explains, indicative of the existence of a message signal at input terminal 1. The output from the comparator 9 may be applied to the terminal 4, 5 by way of three counters 10, 11 and 12 which, in known manner, increase the sensitivity of the arrangement. The steps of preliminary locking, application of the sudden phase shift, and subsequent measuring of the "advance" and "delay" pulses may be effected by a sequencer 18 controlled by another oscillator 19. A set of logic gates may replace the switch 13 (Fig. 2, not shown) and the local clock may comprise an oscillator having an adjustable frequency, the oscillator scanning a given frequency band step-by-step to effect several measuring cycles, the number of recognitions of NRZ messages being recorded for each step (Fig. 3, not shown).

Abstract: 1,066,268. Jet-propelled aircraft. ROLLSROYCE Ltd. Nov. 19, 1965 [Nov. 27, 1964], No. 48433/64. Heading B7G. [Also in Division F1] An aircraft power plant comprises a jet propulsion engine having an exhaust pipe with a first propulsion nozzle, and a jet pipe with a further propulsion nozzle, the engine with its exhaust pipe being movable relative to the jet pipe so that exhaust gases may be exhausted through either nozzle. The engine described is pivotally mounted about a horizontal axis in an aircraft fuselage, and is rotatable between an upright position in which the exhaust gases discharge through the first nozzle (16) to give direct lift or a substantially horizontal position in which the exhaust pipe (12) and jet pipe (13) mate (Figs. 1 and 2, not shown), and the exhaust gases discharge through the rearwardly directed further nozzle (14). The first nozzle (16) has flaps (15) for varying the nozzle area, and these are arranged to pivot automatically as the engine tilts so that the area is a minimum when the angine is upright, and the flaps are in sealing engagement with the jet pipe (13) when the engine is substantially horizontal. In another embodiment (Fig. 4, not shown) the first nozzle (41) is fixed and convergent and the further nozzle in the jet pipe (38) is fixed and divergent, to form with the first nozzle a convergentdivergent nozzle. The power plant may have a supersonic intake (37) which is axially movable to allow the engine to tilt (Fig. 4, not shown), or is movable with the engine and is axially movable in the upright position to form a tap (50) between it and the engine to increase the intake area (Fig. 5, not shown). In a modification of the embodiment of Fig. 4, the engine also has inflatable intake (51), for use in the upright position when separated from the supersonic intake. The engine described is a by-pass gas turbine engine with combustion equipment in the bypass duct, and the jet pipe is provided with reheat equipment.

Abstract: 1,196,976. Delivering cigars and cigarettes. AMERICAN MACHINE & FOUNDRY CO. 25 Oct., 1967 [10 Nov., 1966], No. 48515/67. Heading A2C. In a transfer device for rod shaped articles such as cigars or cigarettes, in which the rods 16 are axially fed as a continuously advancing rod to a station 17 where they are transferred by pneumatic means into seatings 18 of a rotating conveyer drum 20, means are provided for detecting a fault in the seating of a rod 16 on the drum 20 and for causing a cessation of said pneumatic means as a result thereof. Air is continuously fed through tubing 28 to a manifold (66) supplying a number of jets (64) in line along the length of the leading rod 16 about to be transferred. Supplementary jets (88) are also provided to ensure correct seating of the rods 16 in the seatings 18. An air blast from the jets (64) is controlled by a cam actuated oscillating gate mechanism 60 having a number of openings (70) that, when suitably aligned with the jets (64), allow blasts of air to transfer the leading rod 16 to the drum 20 in syncronism with the feed of the rods 16 and the rotation of the drum 20. The seatings 18 include rollers 30, 34. The forward blade member 36 of a detector mechanism senses the presence of rods 16 in the seatings 18 or the presence of misaligned rods (16a) on the drum 20, and the resulting downward or upward movement of the member 36 away from the position shown, actuates, through a control trigger 48, one or other of two latching mechanisms that hold the gate mechanism in an inoperative position so shutting off the air supply.
