Title: Improvements in or relating to nozzles for jet propulsion purposes
Inventor: BROWN DAVID MORRIS
IPC: F02K1/40
Filed: 1957-10-16
Abstract: 844,179. Jet propulsion nozzles. ROLLSROYCE Ltd. Oct. 8, 1958 [Oct. 16, 1957], No. 32391/57. Class 110 (3). In a jet propulsion nozzle comprising a plurality of passage-defining means each effectively forming a gas path of rectangular crosssection leading to an outlet which is effectively of rectangular section in a plane at right angles to the direction of gas flow through the nozzle, the shorter dimension of each outlet is small compared with the longer dimension, the longer dimensions of the outlets are parallel, the outlets are spaced apart in the direction of the shorter dimensions of the outlets to permit the flow of air between them and fairings, which merge smoothly into a pipe portion at the upstream end of the nozzle and converge in the downstream direction, are provided to separate the passage defining means. The nozzle, Fig. 3, is formed by four passage defining means 16, 17, 18, 19 fed with exhaust gases by a jet pipe 14. Each passage has a pair of main walls 20 which converge in the direction of gas flow and top and bottom walls 21 which diverge in the direction of gas flow and have at the outlet dimensions transverse to this direction substantially smaller than the corresponding dimensions of the main walls 20. The cross-sections of the passages have their shorter dimensions extending in the direction in which the passagedefining means are spaced and their longer dimensions parallel. The thickness ratio of the nozzle i.e. the ratio of the diameter of the largest circle inscribable in the outlet from any one passage to the outlet diameter of a plain conical nozzle of equivalent effective area, is of the order of a fifth or less. Fairings 22 between the passages 16, 17, 18, 19 converge rearwardly to form air flow channels of gradually increasing depth. To avoid structural and resonance difficulties, the portions of the walls 20 adjacent the outlet may be formed with a series of shallow scallops. The walls are supported by ties 24 which may extend upstream from the outlet as shown or throughout the length of the passage. The area ratio, i.e. the square of the ratio of the diameter of the escribed circle Dm, Fig. 4, is the diameter Dj of a conical nozzle of the same outlet area should be as high as possible. In a modification, the passage defining means are formed by layers of contacting imperforate tubes which terminate in a rectangular or circular outlet of reduced area as compared with the cross-section area of the tube. Each passage is formed by a layer of tubes. In another modification is formed by two layers of tubes.

Title: A process for the preparation of homogeneous binder-like mixtures of petroleum bitumen and coal tars and of products containing such mixtures
IPC: C10C3/00
Filed: 1938-11-10
Abstract: 506,577. Bituminous compositions. BAUGES MALCHOW GES. Nov. 10, 1938, Nos. 32726, 32727, 32728, 32729, and 32730. Convention dates, Dec. 11, 1937, Jan. 11, 1938, Feb. 9, 1938, Feb. 17, 1938, and Feb. 17, 1938. [Class 22] Homogeneous mixtures of coal tar and petroleum bitumen are formed by selecting as the bitumen component an oxidized petroleum bitumen or one distilled under a high vacuum. The tar may be a viscous tar, very rich in pitch, having a dropping point above 25‹ C. or a tar having a dropping point below 25‹ C. and a low content, amounting to less than 40 per cent of anthracene oil. With a tar having a dropping point less than 25‹ C., the petroleum bitumen employed has , a softening point, Kraemer Sarnow, of at least 54‹ C. A proportion of petroleum bitumen distilled under normal conditions may also be incorporated. In examples; (1) a road-dressing comprises 50 per cent of coal tar having a dropping point of about 30‹ C. and 50 per cent of an oxidized petroleum bitumen having a softening point of 50-60‹ C. ; the softening point of the mixture is about 26-27‹ C. ; (2) a binder for bituminous concrete comprises 50 per cent of coal tar having a dropping point of 40‹ C., 20 per cent of normally distilled petroleum bitumen having a softening point of 54-58‹ C. and 30 per cent of oxidized petroleum bitumen having a softening point of 75-85‹ C., the softening point of the mixture is about 36‹ C. Other examples are given. The binders may be used in making mastic like masses in conjunction with natural asphalt powder or powdered limestone, sand and other aggregates. In an example, a mastic asphalt comprises 45 per cent of natural asphalt powder of Sicilian origin, 4 per cent of binder comprising equal parts of coal tar and high vacuum bitumen, 40 per cent of chips and 11 per cent of sand. Aqueous emulsions may be made from the tar-petroleum bitumen mixtures.

Title: Data transmission system
IPC: H03F3/68
Filed: 1962-08-27
Abstract: 1,011,033. Selective signalling. WESTERN ELECTRIC CO. Inc. Aug. 27, 1962 [Sept. 19, 1961], No. 32794/62. Drawings to Specification. Heading G4H. [Also in Division H4] The invention provides a data transmission system for a plurality of transmitters and receivers, and the embodiment described is a two-direction system. Each transmitter is connected by a two-channel path to its associated receiver, and in normal operation each channel simultaneously passes a different half of a word. However, should one of the channels become inoperative the remaining channel carries the two half-words sequentially. In the system, the states of a set of relays at one station causes a corresponding set of relays at the second station to be set up, and vice versa. As described there are 16 groups of 12 relays. Under normal conditions the 16 groups cause 16 data words to be set up, each word being transmitted as 2 half-words. Each halfword has 10 bits, a start bit, 2 address bits, 6 message bits, and a parity bit. Of each halfword the address bits together provide a 4-bit binary signal indicating which of the 16 groups of relays is providing the 12 message bits which show the state of the relays in the group. Gating circuits cause the relays to be scanned so that the two half-words are stored in a pair of shift registers, one for each transmission channel. The gates also feed a comparatorstore, comprising a 16 x 12 matric of magnetic cores which are set to the states of the relays. This store controls the read-out of the shift registers such that the two half-words are transmitted only if there has been a change in the relays of the group since they were last scanned. At the second station, the halfwords are fed to separate shift registers and checked for parity. The address is derived and the message bits of the half-words used to set the selected relays of a 16 x 12 matrix to the correct states. The system is identical for the reverse direction of transmission, so that alternation of relays in this matrix will cause corresponding change at the first station. In the event of a parity error being detected in one channel it is not immediately assumed that the channel is faulty. Instead the first station is commanded by the second station to transmit data relation to all 16 groups of relays in the normal manner over the two channels. In these circumstances the data is transmitted whether or not there has been a change of state subsequent to the previous scan. If the second station detects repeated errors on one of the channels it is now concluded that the channel is faulty, and it is removed for servicing. The remaining channel is used to carry both halfwords, the half-words being transmitted sequentially instead of simultaneously. When the faulty channel has been repaired it is replaced in circuit, and transmission takes place over both channels. Specification 1,010,823 is referred to.
