Filed: 1974-04-05
Abstract: 1460676 Coupling implements to tractors; hitches C VAN DER LELY NV 5 April 1974 [10 April 1973] 15308/74 Headings A1B and A1P A soil cultivating implement such as a rotary harrow includes a releasable coupling unit which can be coupled to either the front or rear of the harrow frame and can be drawn or pushed when the unit is connected to the quick-hitch system of a traction vehicle. The coupling unit comprises a vertical triangular frame 31 whose apex has plates 34 provided with struts 35A which are connected to the harrow frame 1 by releasably bolted horizontal plates 36. The lower corners of the triangular frame have vertical plates 37 which are connected to horizontal plates 30 releasably bolted to the harrow frame. A gear box 42 is also releasably bolted to the frame by plates 46 so that it can be turned through 180‹ to enable coupling to a vehicle p.t.o. shaft 45 when the coupling unit is in its forward or rear position. The unit is connected to a quick release coupling 32 of a quick-hitch system 48 via a pivoted arm 41 and pin and slot connection 39, 40. The working height of the harrow is determined by a roller 15. Spring biassed lateral guard plates 24 are urged against the side of the frame on rods 23 which are adjustably engaged within sleeves 22 at the end of pivoted arms 11. The guards help crumble the soil and move away from the frame when engaged by stones to prevent tine damage.

Title: Improvements in feeding devices for steam boilers
IPC: F22D1/42
Filed: 1922-06-01
Abstract: 195,303. Meinehe, F. June 1, 1922. Feed-water, supplying and controlling.- Feed-water is delivered by an exhaust steam injector to a mud drum in which the pressure and temperature are automatically regulated under the combined action of the injector and boiler feed pump, and whereby scale is precipitated. The injector 1 delivers water from the pipe 4 to the mud drum 5 from which it is drawn in purified form through the pipe 7 by a feed pump 6 and passed to the boiler feed pipe 8. The pressure in the drum is regulated by the pump and the injector jointly and automatically and is maintained at about 70 lbs. whilst the temperature is kept above 130‹ C. so that impurities are precipitated. For regulating the temperature, the casing 9, Fig. 2, which is connected to the injector at the flange 10 and with the mud drum at the flange 11, is provided with an extension having a live steam inlet 13 with an outlet of injector form 22. A combined valve 17, 21 under spring control 20 governs the injector supply and live steam flow. When the injector is feeding more or less freely, the valves 21, 17 are opened up so that more or less live steam for heating this supply is admitted. When the engines are not working, the temperature is maintained in the mud drum by the admission of live steam thereto through a reducing valve.

Title: Improved apparatus for predicting the future position of a target or other moving object
IPC: F41G5/08
Filed: 1918-09-24
Abstract: 167,191. Holden, H. C. L. Sept. 24, 1918. Methods of sighting.-Relates to apparatus for predicting the future position of a moving object, and consists in means for giving the linear displacement of the object in two directions at rightangles to each other during a predetermined period, such as the time of flight of a projectile. In the form shown, as applied to anti-aircraft gunnery predicting-apparatus, a sighting device e, Fig. 1, at an observing station is elevatable to maintain the sight on the target by operating a hand-wheel f, which displaces axially along a shaft c a bar a, the upper end of which bears against the sight e. The bar a may be raised to correspond in height to any given height of target. The shaft c drives a magneto h in circuit with a rheostat p which may be set for the time of flight t, and voltmeter i then indicates the displacement of the target along the line of sight in time t. The sighting-device e is rotatable in azimuth by a hand-wheel m, which similarly drives a magneto n in circuit with two rheostats which may be set for horizontal range and time of flight; a voltmeter o then indicates the horizontal displacement of the target at rightangles to the line of sight in time t. The rheostats and voltmeters may be situated at a central station, to which the horizontal range and bearing of the target is transmitted by telephone or otherwise. At this station is a predicting-instrument shown in Figs. 2 and 3, comprising a fixed arm r along which an arm s may be displaced proportionally to the horizontal range. A carriage w may be displaced along the arm s proportionally to the change in horizontal range in time t, and a vertical pillar 1 on the carriage w may be displaced at right-angles to the arm s proportionally to the displacement of the target at rightangles to the line of sight in time t. The horizontal distance of the pillar 1 from the zero point v of the instrument is then the future horizontal range after time t. The pillar carries a slide 4 rotatable horizontally in a guide 5 pivoted immediately above the zero point v. The slide carries a drum 6 on which are curves showing fuze and quadrant elevation plotted axially against height plotted peripherally, these curves being read against fixed pointers 7. The bearing of the target is set on a graduated arc 8 by a hand-wheel 9, and to it is added the angle between the axis of the drum 6 and the fixed arm r by means of a parallel link device 10, the pointer 11 of which indicates the future bearing of the target after time t.

Abstract: 1390081 Colour television GENERAL CORP 5 April 1972 [5 April 1971] 15703/72 Heading H4F In a colour television receiver for a PAL signal having "swinging" bursts, the bursts for every second line are phase-inverted, the resulting bursts controlling a reference oscillator 20 for R-Y demodulation, the phase of the oscillator being the mean of the phases of the bursts fed to it in two successive line periods. A reference oscillation for B-Y demodulation is produced in response to the received bursts in a separate oscillator 5. The phase inversion is achieved by a 180 degree phase shifter 16 and a switch 17 operated at half line frequency. In the embodiment shown the chrominance signal is fed to the R-Y demodulator 3 via 16 and 17 to provide the R-Y component always of the same polarity. In another embodiment (Fig. 4, not shown) the chrominance signal is fed to demodulators 2 and 3 via a one-line delay line and switch to provide to the demodulators every second line of information repeated twice. In a further embodiment (Fig. 3, not shown) the chrominance signal is fed directly to demodulators 2 and 3, the output of reference oscillator 20 being switched at half line frequency.
