Title: Coastal navigation aid
IPC: G01S1/44
Filed: 1976-02-05
Abstract: 1516243 Radio navigation STANDARD TELEPHONES & CABLES Ltd 5 Feb 1976 04553/76 Heading H4D A coastal marine navigation system comprises a group of n (e.g. 6) beacons each transmitted bearing information signals in the form of an audio frequency signal modulated onto a VHF carrier common to the group, the beacons transmitting one at a time in a time sharing sequence Fig. 2, in which, for each beacon, during some sequences said bearing information signal is of a first kind, having a long (e.g. 62 sec) duration, and directly utilizable aurally by a mariner equipped only with a VHF radio receiver and during other sequences said signal is of a second kind, having a short (e.g. 1 sec) duration, and only utilizable by an automatic auxiliary unit coupled to said VHF radio receiver, the transmissions during successive sequences being such that every n+1<SP>th</SP> (e.g. 7th) from the group is the first type and all the others are the second type. Each beacon is generally of the kind described in Specification 1,429,743 with the beacon bearing being indicated by the timing of a minimum in the amplitude modulation. The keying of the amplitude modulation during the long signal is as shown in Fig. 3, the start of the cycle of relative phase variation between the signals tranmitted by the two aerials being indicated by a 4 sec continuous start pulse, the modulation then being interrupted for 1À05 sec to 1À55 sec to indicate the beacon sequence number, and the modulation then being keyed for 64 audio beats (as heard on the VHF radio receiver) each lasting À6 sec, spaced by À15 sec. An interruption of modulation then follows 1À1 sec to 1À7 sec, indicating how many degrees of azimuth are represented by each of the 64 beats (i.e. the granularity), and the long signal ending with a morse code identification of the beacon. A receiver, with auxiliary unit Fig. 6, analyses the durations of the various parts of the long signal in timing circuit 60 and feeds the beacon sequence and the granularity to a store 63 for use in a computer 64, and feeds the beacon cycle start time direct to the computer. This enables the computer from the number of the beat exhibiting minimum amplitude to control a display 65 showing the bearings to beacons within range of the receiver, against their number. The short pulses Fig. 5 (as received) have a 0À2 sec initial portion of reduced (half) amplitude, with a level detector 62.in the receiver determining the increase in amplitude and starting a cycle count in the computer 64 until the bearing indicative amplitude minimum. The system thus gives a position fix for both mariners equipped with a VHF receiver only and those equipped with the receiver and auxiliary unit, the latter obtaining much faster fixes. If the mariner knows the sequence numbers of the beacons in range order, he may feed these into the computer and shorten the time he has to wait for all the fix giving bearings (Fig. 7, not shown).

Abstract: 1,214,627. Chromatographic fluid carrier pressure control. PERKIN-ELMER Ltd. 23 Jan., 1968 [2 Feb., 1967], No. 5183/67. Heading B1L and B1X. A carrier gas pressure control system which allows the pressure of the carrier gas passing to gas chromatography column 7 to rise in a selected way from a steady initial valve to a steady final valve comprises a feed system for carrier gas 1, and a control system operated pneumatically by a control gas 2, sintably compressed air. Initially, taps 10, 11, 12 and 15 are closed. Taps 11 and 15 are then opened and flowmeter 13 adjusted to the valve on a calibration curve corresponding to the selected pressure rise rate required. Valve 5 is then adjusted so that the required final pressure is indicated on gauge 8. Taps 11 and 15 are then closed, tap 12 opened and regulator 16 adjusted so that reducing valve 6 is throttled to produce the required initial pressure as indicated on gauge 9. The first stage is then commenced; when the phase of selected pressure rise is to be instituted, tap 12 is closed and tap 11 opened. The carrier gas pressure then builds up to the final selected value by causing valve 6 to open and admit the full final pressure of carrier gas to which valve 5 is adjusted to the column. In a modification (see Fig. 2, not shown), the branch containing regulator 16, tap 12 and restrictor 17 is eliminated by replacing valve 6 by an adjustable valve combining the functions of valve 6 and regulator 16. The system is also stated to be of application to liquid chromatography. (For Figure see next column)

Abstract: 433,627. Variable-speed and reversing gearing. CLOUDSLEY, J. L., 5, Chancery Lane, London. Feb. 17, 1934, No. 5325. Addition to 405,453. [Class 80 (ii)] In infinitely-variable friction gearing of the torus-disc type combined with planetary reversing - gearing, as claimed in the parent Specification, the output shaft 28 of the combined unit supports the entire reversing- gear which can be detached as a whole by removing nuts 40. The nuts 40 secure a casing 27 of the reversing-gear to a casing 41 of the disc gearing. The shaft 28 is supported near its outer end in a ball bearing 29 which takes the thrust of planet pinions 12 of the reversing-gear and also any thrust in, say, the cardan shaft of a vehicle, exerted upon a transmission flange 22. The shaft 28 is supported near its inner end within a sleeve 8 in a ball bearing 30 which takes the opposite thrust of the pinions 12. The sleeve 8, which communicates the drive from the disc gearing, is supported in turn in a roller bearing 52 in a web 53 of the casing 41. The sleeve 8 has a detachable splined connection 26 with the driven drum 6 of the disc gearing, and has also gear teeth 33 meshing with the pinions 12 which are supported in a spider comprising a hub 34 and an outer ring 35<1> connected by spindles 11. The pinions 12 mesh on the other side with a gear 37 splined on the shaft 28 and thrust supported by the bearing 29. The rear end of the disc gearing shaft 3 is supported on a bearing 51 on the forward end of the shaft 28, and a nut 42 takes end thrust. Change from forward to reversed driving is effected by sliding a sleeve 35 splined on the ring 351 from engagement with clutch teeth 46 on the gear 37 into engagement with fixed teeth 44. There are lubricating passages 47, 48, 49.

Title: Unsymmetrical dimethylhydrazine
Inventor: HORVITZ DAVID
IPC: C07C241/02
Filed: 1957-02-18
Abstract: Unsymmetrical dimethylhydrazine is prepared by reducing N-nitroso dimethylamine in an aqueous medium by the use of zinc, aluminium, amalgamated zinc or amalgamated aluminium in the presence of an alkaline agent reactive therewith or by the use of amalgamated zinc or amalgamated aluminium in a neutral aqueous medium.  The alkaline agent is preferably caustic alkali and is preferably used in an amount which is less than the stoichiometric equivalent of the metal and which is such that the mol. ratio of caustic to nitroso compound is from 0.01 : 1 to 2 : 1.  The reaction may be primed by the addition of previously formed unsym. dimethylhydrazine.  Organic solvents such as benzene, toluene, methanol, ethanol, glycol and diethyl ether may be present during the reaction.  The reduction medium may be heated without further treatment to distill out the unsym. dimethylhydrazine.  The N-nitroso dimethylamine starting material may be prepared by reacting the HCl or H2SO4 salt of dimethylamine with sodium nitrite in an aqueous medium.  The resulting mixture yields N-nitroso dimethylamine as a separate layer upon treatment with alkali.  The two-layer system or the separated N-nitroso dimethylamine may be used for the reduction treatment.
