Title: Directional antenna systems
IPC: G01S3/14
Filed: 1974-01-30
Abstract: 1472893 Antennae; direction finding A W RUDGE and H WUNNENBERG 27 Jan 1975 [30 Jan 1974] 4313/74 Headings H4A and H4D A directional antenna system comprises a plurality of direction finding antenna which may be integrated with a communications antenna on, e.g. a communications satellite, which is to be maintained in the optimum reception position, by a follow-up device which is controlled by the direction error signals produced by an analysis circuit connected to receive signals from the direction finding antennae, which comprise at least two offset parabolic reflector antennae arranged to produce a common direction finding beam. As described, a two axis direction finding system, Fig. 3, comprises primary radiators F1, F2, F3, F4 situated at the focus of respective reflectors R1, R2, R3, R4 which each comprise an offset portion of a paraboloid (having an apex, e.g. 51 in Fig. 1, not shown). Antennae A1, A2 and A3, A4 provide directional error signals on the y and x axes respectively. The directional error signals are analysed in the passive microwave circuit of Fig. 4 comprising hybrid coupler H1 connected to antennae A1, A2 to produce a phase error signal S#1,2 at its a2 output, hybrid coupler A2 connected to antennae A3, A4 producing the orthogonal phase error signal S#3,4, and hybrid coupler H3 which produces the sum signal S#1,2 3 4 from all the antennae A1-A4. These signals are used in a known follow up control system to maintain the direction finding antenna in the direction of maximum signal reception. In Fig. 5 an embodiment for use in a communications satellite comprises the four direction finding antennae F1-F4 and in addition a fixed antenna F5 having a large half power beam width for transmission of telemetry signals and reception of command signals, and is connected to its TX/RX device Sp/Ep, which is also used to provide a signal equivalent to the sum signal from the direction finding antennae. This signal r is fed to error signal analysis circuit ASE to serve as the sum signal with reference to the difference signals fed from outputs a2 of hybrid couplers A1 and A2. In this case the sum signal present at the output a1 of hybrid coupler H3 may therefore be coupled to the communications receiver/transmitter Sn/En whereby the direction finding antennae may together constitute the main communications antenna of the satellite. As the analysis circuit cannot directly recognize the sign of the input directional error signals variable phase shift devices P11, P22, P33, P44 are provided and are commutated by a pulse train T to produce a small known phase shift in the error signals whereby the sign thereof may be recognized in ASE.

Title: Method and apparatus for heating gases to high temperatures
IPC: F23C99/00
Filed: 1966-02-01
Abstract: 1,141,741. Electric heating apparatus. NORTHERN NATURAL GAS CO. 1 Feb., 1966 [2 Feb., 1965], No. 4337/66. Heading H5H. Apparatus for heating gases comprises a pilot burner, fed with a combustible mixture and ionising additives e.g. KC1, which ignites a second combustible mixture, a passageway for products of combustion and first and second electrodes in the passageway creating an electrical discharge through the products. Methane or natural gas containing powdered KC1 fed through a tube 23 burns with air or O 2  fed through a tube 17 to form on tip 20 a pilot flame when ignited by a R.F. spark from a source 24. The tube 23 is slotted to obtain some premixing of the fuel and air before ignition. A second combustible mixture of natural gas and air is supplied through an opening 37 and passes to the pilot flame through a perforated sleeve 39 and openings 38. Combustion takes place in a metal tube 50 within a cooled glass tube 40. To complete combustion and increase ionisation of the KC1 a low power discharge is applied to the gases by connecting a highvoltage source 51 across tube 50 and a cooled electrode 42 both having discharge points 50a, 42a. The gases then flow through a second glass tube 57 having electrodes in the form of orifice plates 55, 59 at each end. A high-voltage source 65 is connected across these electrodes to apply a distributed discharge through the hot gases. Chemical reactions may be carried out by feeding reactants into the burner at any stage preferably the last, through an opening 68 in electrode 42 and further pairs of electrodes may be positioned downstream of electrodes 55, 59. If combustible gases contaminate the reaction products or if non-combustible gases are to be heated, the combustible mixture may be gradually replaced by non-combustible gases and the heat input from the discharge between electrodes 50, 42 increased.

Title: Article counting and container filling machine
IPC: B65B57/20
Filed: 1966-02-03
Abstract: 1,073,398. Filling containers with tablets etc. LAKSO CO. Inc. Feb. 3, 1966 [May 20, 1965], No. 4795/66. Heading B8C. An apparatus for feeding articles, e.g. tablets, into containers 16 comprises a series of slats 24 each provided with cavities into which the articles are fed and from which they are ejected into shoots 22, when the slats are inverted, and thereby into the containers. The articles are fed from a supply into a hopper 30 where they form a stack (38), Fig. 5 (not shown). A sensing device (40), e.g. photo-electric cell, stops the supply when the stack (38) reaches a predetermined height. The slats 24 move anticlockwise in a closed path continuously and when they pass below the stack (38), the cavities are filled with articles. The slats 24 may be vibrated longitudinally by means of linkages (84), (86), Fig. 6 (not shown), connected to an eccentric 88. A brush 42 removes any excess articles from the slats. The filled slats pass an inspection area (46), Fig. 5 (not shown), where any faulty articles may be replaced manually. A device for detecting empty cavities may be used to stop the machine or alert an inspector. This device comprises an air jet (96), Fig. 7 (not shown), connected to an air chamber (94) fixed adjacent the slats. Each cavity in the slats is provided with an aperture (90) so that in the absence of an article, the air from the jet (96) displaces a paddle (98) which causes a shutter (100) to interfere with a photo-electric cell (102). From the inspection area (46), Fig. 5 (not shown), the slats 24 pass under a guard (48) which holds the articles in the cavities when the slats are inverted. Each slat 24 extends from, and is fixed to a rod (50), Fig. 2 (not shown), which is mounted in an element (52) attached to a pair of chains (60). Each rod (50) has a cam follower (56) which follows a cam track on a plate (58). The cam track causes the rods (50) to reciprocate once as they move along the lower path and hence the slats 24 are firstly moved transversely to the guard 48 until they are fully extended at a peak 28 and then retracted as they travel along the lower part of their path. When the slats are moved transversely to the guard (48), Fig. 4 (not shown), they pass above the shoots 22 into which the articles from the cavities in the slats fall. The shoots 22 are driven at the same speed as the slats 24. The articles fall down the shoots 22 into containers 16 which are moved along at the same speed as the shoots 22 by a screw 12. A hand wheel 32 may be provided to test the synchronism of the containers and the shoots &c. The slats 24 can be replaced by slats with different sized cavities. Two or more articles may be accommodated in one cavity to speed the feed, Fig. 8 (not shown).
