Filed: 1928-05-09
Abstract: 314,639. Smith, C. C., and Imperial Chemical Industries, Ltd. May 9, 1928. Manures.-Fertilizer salts, for instance calcium nitrate or a mixture thereof with ammonium nitrate, are granulated by forming the molten salts into thin streams or drops and bringing them into contact with a body of oil, such as kerosene, at a lower temperature. A spraying nozzle or a centrifugal rotor immersed in the oil may be used to distribute the salt, or the latter may be exposed to the atmosphere before contacting with the oil, in which case surface solidification may precede solidification bv the oil. The boiling point of the latter should exceed the temperature of the molten salt. The granules obtained are coated with a film of oil which prevents access of moisture with consequent casing.

Abstract: 706,430. Electronic counting apparatus. NORTHROP AIRCRAFT, Inc. June 11, 1951 [June 12, 1950], No. 13812/51. Class 106 (1). (Also in Group XL (c)] Fig. 4 shows a binary counter comprising a cascaded connection of trigger circuits of the type shown in Fig. 3 in which negative-going triggering pulses from source 14 are applied via rectifier 13 to the anode 2 of the cold-cathode gas tube 1. Cathode 4 is connected to earth via neon tube 21 and constant voltage source 22 in parallel with isolating resistor 20 and constant voltage source 15. The voltage difference between sources 15 and 22 is made equal to or slightly less than the maintaining voltage of tube 21. If initially there is a discharge between anode 2 and cathode 3 the voltage drop across resistor 10 limits the voltage of source 7 to the maintaining voltage of the tube 1. Capacitor 17 charges to a potential exceeding that of supply 15 so that when a negative pulse is applied to anode 2 the discharge to cathode 3 is interrupted and as the anode voltage rises a discharge path to cathode 4 is initiated and neon 21 fires. A subsequent pulse applied to anode 2 extinguishes the discharge to cathode 4 and re-instates that to cathode 3. The maintaining voltage of neon 21 may be selected to be close to the potential difference between cathode 4 and earth so that the constant voltage source 22 may be dispensed with. In Fig. 4 the positive pulse produced at cathode 4 of the first tube 1 when it is triggered over by a negative pulse at anode 2 is differentiated by capacitor 30 and rectifier 31 and the negative going resulting pulse is applied via rectifier 13a to trigger the second stage S. Specification 706,423, [Group XL(c), is referred to.

Title: Improvements in detection and signalling systems
IPC: B61L1/20
Filed: 1960-04-20
Abstract: 918,790. Electric selective signalling systems. GENERAL PRECISION Inc. April 20, 1960 [April 23, 1959], No. 13879/60. Class 40 (1). A passive responder (i.e. a circuit having no power supplies of its own) that emits a response electrical signal upon being influenced by an interrogating electrical signal radiated by an interrogator comprises a number of tuned circuits each resonant at a different frequency and operative to determine a selection of frequencies to be present in the responder signal and at least one of the tuned circuits has one or more environmental condition-sensing (e.g. temperature, humidity, &c.) electrical elements in circuit therewith, each of which elements acts to render operative or to disable the associated tuned circuit according to the value of the condition being sensed by it whereby evidence of that value is provided by the presence or absence in the responder signal of the frequency corresponding to that particular tuned circuit. In the first embodiment described, Fig. 2, a central office 30 transmits a spectrum of frequencies to each of a number of responders, of which one is shown. The spectrum of frequencies is received by each responder in a circuit 38 and passed via tuned circuits 48, 50, 52 to modulate an R.F. oscillator T1, and retransmitted back to the central office, the carrier current of the received spectrum being rectified 40 to provide D.C. power. However, because of the tuned circuits 48, 50, 52, some frequencies of the spectrum are inhibited and are not retransmitted. These represent firstly the identity of the particular responder and secondly whether or not any one of a number of switches 22 has gone open circuit by virtue of the particular variable being sensed having exceeded a certain level. In a second embodiment (Fig. 5, not shown), only one frequency is transmitted by the central office and each responder includes a number of oscillators tuned to different frequencies. In a further embodiment the responders transmit their various frequencies successively. In the preferred embodiments, the condition being sensed is the temperature of axle bearings on railway vehicles and the Specification contains a list of alloys which fuse at fairly low temperatures, the appropriate alloy being chosen so that it fuses before the bearing reaches a dangerous temperature. Specification 917,755 is referred to.

Title: Waveguide coupler arrangements
IPC: H01P1/213
Filed: 1972-03-30
Abstract: 1377742 Directional filters MARCONI CO Ltd 30 March 1972 [8 May 1971] 13905/71 Heading H1W A band-separating filter comprises a narrowwall waveguide directional-coupler provided with symmetrically positioned reactances near the opposite narrow walls of the coupler within the coupling zone. In the self-explanatory arrangement of Fig. 3, the reactances take the form of two arrays of ports 8, 9 and in a modification (Fig. 5, not shown) solid conductive members bounded by the same line as is defined in Fig. 3 by the ports. Within the coupling zone, the waveguides are wide enough to support both the TE 10  and TE 20  modes and the reactances are so dimensioned that the TE 20  waves are close to cut-off. The TE 10  mode is propagated as a wave having co-phasal components in respective waveguides and the TE 20  as a wave having components in antiphase in respective waveguides (the two modes are sometimes referred to as "odd" and "even" modes in some accounts of this kind of coupler). The two modes are indicated respectively by dashed and chain dotted lines, the resultant by a solid line. Because of frequency dispersion, a band centred on f 1  near the cut-off frequency of the TE 20  mode is coupled between ports 3 and 5, whilst a band centred on a higher frequency f 2  is coupled between ports 4 and 5 (Fig. 4, not shown). The ports are matched to the coupling zone by steps. The ports 9 are spaced by #/8 (at the mean working frequency) over the greater part of the coupling zone. At the edges the ports 8 diminish in diameter and the spacing is gradually reduced according to a Chebyshev or binomial coefficient law.

Title: Improvements in apparatus for sealing containers of powdered milk and other light powdered materials
IPC: B65B31/02
Filed: 1946-05-08
Abstract: 625,903. Sealing containers of milk &c. powder. TRUFOOD OF AUSTRALIA, Ltd. May 8, 1946, No. 13961. Convention date, May 8, 1945. [Class 49] [Also in Group XVII] Containers of powdered milk are sealed in chambers mounted on a rotary table, each chamber holding a container being subjected to a first, partial, evacuation during the early stages of which the air is withdrawn through an orifice or orifices of relatively small area at such a rate as to avoid distrubance of the container contents, and a second evacuation to a pressure approaching absolute vacuum; the container is then sealed in the chamber, after which the chamber is vented to atmosphere and the container removed. After the second evacuation, the chamber may be supplied with inert gas at low pressure. As shown, cans 71, which have been previously filled with powdered milk and on the upper ends of which lids 72 have been placed, Fig. 13, are transferred by means of a reciprocating arm from a conveyor on to platforms 73 located beneath and rotating with chambers 45 mounted on a rotary table 42, Fig. 1. As rotation proceeds each platform 73 is raised by can track 77 to introduce the can into the chamber 45 above and to seal the lower end of the chamber. Down and up movement of a roller 94 on a can track 95 moves a yoke 90 and with it an arm 89<SP>1</SP>, Fig. 13, to lower a magnet 83 against spring pressure into contact with the lid 72 and to lift the lid from the can. Chamber 45 is connected by pipe 46 to a port in a valve seat plate communicating successively with ports 57, Fig. 5, in a stationary valve plate 49 connected to a suction pump. Ports 57 are connected by a groove 52 tapered towards the end with which each port in the valve seat plate is first in register, and ports 57 are provided with needle valves adjusted so that the effective size of the ports increases progressively, sc that air is withdrawn at low velocity during the early stages of the exhaustion and more rapidly later in order to avoid disturbance of the powdered contents of the can. A vacuum equivalent to 27 inches of mercury is applied to channel 52; the chamber 45 is then connected through a further channel 53 similar to channel 52 with a second vacuum pump to reduce the pressure to within quarterinch of mercury of absolute vacuum. The chamber is now connected through a port 69, Fig. 5, with a pressure gauge and then through port 68 with a supply of inert gas at low pressure, preferably nitrogen at a pressure equivalent to 20 inches of mercury. The lid 72 is now lowered on to the can, a gasket or sealing composition in a peripheral recess 82 of the lid engaging a lip surrounding the opening in the can, and the chamber is vented to atmosphere through a further port 70 in the valve plate, after which platform 73 is lowered and the can unloaded on to a conveyer. More than two channels may, if desired, be provided in valve plate 49 connected to an equivalent number of vacuum pumps.

Abstract: 143,563. Luxmore, W. April 17, 1918, [Convention date]. Differential or balance gearing for motorvehicles comprises clutches with dovetail teeth which are disengaged by cams to allow overrunning of one driven member. A driving housing in parts 13, 14, Figs. 1 and 9, has a central disk 15 having dovetail teeth 25, 36 adapted to be engaged by like teeth 24, 35 on annular clutch members 20, 21 axially slidable in differentially driven members 10, 11. The clutches 20, 21 have a series of cams 28, 39 by which they are thrust into engagement when acted on by " timers " 51, 75 circumferentially movable in cam recesses 44, 48 in rings 43, 47 secured to the driving-parts 13, 14. The timer 51, Fig. 9, having come to the end of its recess 44, has thrust the clutch 20 into engagement, while the dovetailed teeth were suitably disposed. The timer 75 has come to a neutral position, leaving the clutch 21 free to be disengaged positively to allow overrunning by one of a pair of cam controllers 66, 67, shown also in Fig. 5. These controllers have interlocking teeth passing through a hole 73, Fig. 1, in the disk 15, and have at diametrically opposite points lugs 64, 70. The lugs 64, 70 project between the upturned ends such as 82, 83 of elastic rings 58, 81, upon which the timers 51, 75 are pivoted. The arrangement is such that lost motion between a lug 70, Fig. 3, and the ends of the ring 81 allows the timer 75 to come to inoperative position, upon which the controller 67 by cam projections 72 acting on cams 38 on the clutch 21 thrusts that clutch out of engagement.

Title: An improved method of and means for measuring the staple length of fibres
Inventor: LORD EDMUND
IPC: G01B11/02
Filed: 1953-05-20
Abstract: 781,453. Photo-electric indicating systems. BRITISH COTTON INDUSTRY RESEARCH ASSOCIATION. Aug. 20, 1954 [May 20, 1953], No. 14111/53. Class 40 (3). [Also in Group IX] The staple length of fibres in a specimen of loose fibres is determined by preparing a double fringed layer having its fibres substantially parallel and measuring distance between two positions at opposite ends of the specimen at which the maximum rate of charge in fibre numbers occurs on movement to each side of the position. As shown, the specimen (Figs. 1 and 4) is spread out on a platform 10 which is movable by means of a flexible tape running over each drum and driven manually from a knob outside the housing. Light from a source 22 passes through condenser 23, slit mesh 24 and lens system 25 and is reflected by a mirror 26 past a fixed partition 29 so as to form two slightly separated parallel lines of light 27 on the surface of the specimen. Light reflected from each of these lines falls on the corresponding one of photo-electric cells 30. This arrangement is triplicated and the two sets of three cells are connected in opposition to each other and to a sensitive galvanometer. Potentiometers 31 are provided to adjust cell sensitivity. In use, the platform is moved until the galvanometer reading is a maximum, this indicating that the maximum rate of charge of the number of fibres on each side of the line takes place. A counter 19 geared to the platform is then set to read zero. The platform is then adjusted to the other end of the sample and a maximum meter reading found at that end when the counter reads the distance x which is the nodal length of the fibres. In a modification (Figs. 5, 6, and 7, not shown), the specimen is attached to a platform which is then carried by a manually-driven belt. An indicating drum may be clutched at will to the belt to indicate the nodal distance and a weighted string around the indicating drum is used to set the indicating drum to zero automatically.
