Title: Improvements in or relating to directional wireless systems
IPC: G01S1/02
Filed: 1934-08-03
Abstract: 442,164. Directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House. Victoria Embankment, London, and SMITH, S. B., 1, Braemar Avenue, Chelmsford. Aug. 3, 1934, No. 22720. [Class 40 (v)] A radio beacon of the Adcock type is used for radiating overlapping fields with a median-line of equal signal strength. There is a comparatively simple arrangement of shielded and balanced feeder-lines. As shown in Fig. 2, two vertical aerials A, B, spaced substantially half-a-wavelength apart, are alternately excited (a) in phase to give the field diagram 3, 4, Fig. 1, and (b) in phaseopposition to produce the field diagram 1, 2, Fig. 1, the equi-signal lines being shown at 5, 6. The change-over switches S1 ... S4 simultaneously serve as keying means, sending say a morse " dash " on the right-hand (or phase-opposition) position, and a morse " dot " on the left-hand position, when the aerials A, B are being excited in-phase through the supply M. The screened horizontal feeder lines C, D comprise known phase-matching and synchronizing networks E, F. In a modified arrangement three aerials are coupled in pairs to produce three radiating lines of equal signal-strength.

Patent GB-857902-A (GB)
Title: Improvements in the production of oximes
Filed: 1959-07-03
Abstract: A process for the production of an amime comprises reacting a secondary nitroalkane on a nitrocycloalkane with carbon monoxide and an alkanol containing 1 to 4 carbon atoms in the presence of a base at an elevated temperature and pressure.  The nitroalkane or nitrocycloalkane may be employed in the form of an alkali metal or ammonium salt.  The carbon monoxide may be optionally diluted with an inert gas such as hydrogen or nitrogen.  Starting materials specified include nitro-cyclo-pentane and 2-nitropropane and the sodium and potassium salts of nitrocyclohexane.  Alkanols specified include those containing from one to four carbon atoms. The examples relate to the preparation of cyclohexanone oxime.
Patent GB-424008-A (GB)
Title: Improvements in or relating to the production of fertilizers
IPC: C05F5/00
Filed: 1933-08-18
Abstract: A process of treating peat to render it suitable for use as a fertilizer consists in mixing the peat in the presence of water with sugar defecation chalk, which neutralizes the acidic character of the peat, adding aluminium sulphate, acid sodium phosphate and earth taken from land planted with crucifers, and then submitting the whole mass to aeration for a time sufficient to produce fermentation.  The mass may be aerated at a temperature of 40 DEG  C. for 48 hours, and then aerated mixtures of peat, water, sugar defecation chalk and the salts are added to the aerated mass and the whole then alternately aerated and rested every 12 hours for a total period of 5-6 days from the commencement of the first aeration when maximum fermentation is obtained.  The product of these processes may be used directly as a fertilizer or it may be incorporated into fresh neutralized peat, the mixture being preferably compressed and, if desired, crushed to a fine powder.

Title: Achromatic depth-of-field correction for off-axis optical system
IPC: H04N5/74
Filed: 1971-04-19
Abstract: 1336684 Modulating light RCA CORPORATION 19 April 1971 [9 March 1970] 23185/71 Heading H4F [Also in Divisions G2 and H1] An optical system for projecting an image of an object 24, Fig. 1, by arranging a substantially collimated beam to be reflected by it through a projecting device 17 and on to a viewing screen 18, in which the object is arranged other than perpendicularly across the optical axis of the projection device, has a prism 21 arranged to intercept both light incident upon the object, and the light reflected by the object, to present the object as apparently orthogonal to the optical axis of the projection device. As described, the object 24 is the reflecting screen of a Schlieren-type display, and a stop 19 is located at the focal point of the projection lens 17. The reflecting surface is as shown in Fig. 2. Insulating substrate 22, e.g. of glass, carries supporting conductors 23 which are electrically connected, which conductors 23 carry, spaced from 22, a light-reflective, electrostatically deformable, normally flat metal film 24, e.g. of alloys of Ni, Cu, or Al. The film 24 is pervious to an electron beam so that charges build up on substrate 22 (e.g. as at 26), which charges lead to deformation of the film, so deflecting incident collimated light. The prism may be placed adjacent the face-plate of the electron tube, or cemented thereto.

Abstract: 317,633. Gill, H. A., (Naamlooze Vennootschap, Verschure & Co.'s Scheepwerf en Machinefabriek). Aug. 13, 1928. Cylinder machines; feeding.-Tough and sticky material is divided, during transference from a hopper A to a conveying belt P by a cylinder B fitted with radial slots in which slide cutting- knives E, the outer and upper ends' of which are furnished with bosses F operated bv eccentric mechanism G, K, L, M. The ends of the knives protrude beyond the periphery of the cylinder as they pass the mass of dough in the hopper, each blade thus scraping away a portion of the mass for delivery to the belt. A scraper R prevents any material from being carried right round the cylinder back into the hopper. The material is delivered past the spring-pivoted flap T and its fall is broken by the inclined plate S. Excessive movement of the flap T due to obstructions may be utilized to stop the driving-motor.

Abstract: 686,925. Ignition systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 21, 1951 [Sept. 22, 1950], No. 23337/50. Class 7 (iv). In electrical ignition apparatus comprising for each fixed electrode 12 of a jump-gap distributer, a two electrode spark gap 14 and a con-. denser 15, a connection between the one electrode of the spark gap 14 and the one electrode of the condenser 15 and which is connected to the corresponding fixed distributor electrode 12, the other spark gap electrode being connected to the one electrode of a corresponding surface discharge sparking plug 11 and the other condenser electrode being connected to the other sparking plug electrode, it is arranged that when the moving distributer electrode 51 registers with said fixed electrode 12 sufficient voltage is developed in magneto or induction coil to break down the gap between the registering distributer electrodes whereupon the condenser is charged to a lower voltage than that required to break down the distributer gap, the two electrode spark gap 14 breaks down the condenser discharges through the latter and the corresponding sparking plug 11. The spark gaps 14 break down at a voltage lower than that required to rupture the distributer gap. Inductances such as 16 are connected in each discharge circuit to limit the peak current and increase the duration of each discharge; the inductances may, however, be omitted or inserted elsewhere in the circuit. Electrical values of the components are given.

Abstract: 478,116. Detecting approach of overtaking vehicles. GELSDORF, E. Sept. 7, 1937, No. 24359. Convention date, Sept. 24, 1936. Drawings to Specification. [Class 118 (ii)] Ultra-audible or very high frequency audible sound waves are used to indicate that a following vehicle wants to overtake. The sound waves are generated by a Galton pipe operated by compressed air from a gas container or from the engine cylinder or by the use of a rubber ball or foot-operated bellows. The sound waves are received by a magneto-strictive receiver and after amplification cause the operation of a red signal visible to the driver, a red signal visible to the following driver and an audible signal. If it is safe to allow overtaking, the driver operates a switch which alters to green the signal visible by the overtaking vehicle, gives a red signal to approaching vehicles and lights a green pilot lamp. These signals are cancelled and the apparatus restored to normal after a 20 second time lag controlled by a bi-metallic strip.
