Filed: 1944-04-29
Abstract: 584,378. Turn-wrest ploughs. SHARP, T. April 29, 1944, No. 8076. [Class 6 (i)] The draw-bar of a tractordrawn, one-way plough which can swing across from side to side of the tractor is provided with a joint at an intermediate point in its length so that the plough and the rear portion of the drawbar may be lifted, using this joint as a pivot, by a lifting member carried on the tractor, the said lifting member being also capable of swinging from side to side. In the form shown, the plough is provided with a pair of land-wheels 26 and is coupled to a tractor by means of a draught-bar comprising two parts 15, 16 joined by a horizontal hinge 17. The rear portion 15 of the draught-bar is pivotally attached to a coupling frame 27 which permits relative lateral movement between tractor and plough. The beam 21 which carries the shares (not shown) is rotatable about bearings 20 and 22 in the main frame 23, 24, and is slightly cranked near its forward end so that the land wheels are out of alignment with the line of travel and the plough will tend during motion to be drawn to one side of the tractor. The main frame 23 is attached by a chain 30 to a jib 31 carried on the tractor chassis. This jib is actuated by gearing 33, 35 and 41, 42 and can be swung from side to side within the confines of a framework 32. With the jib raised, the interchanging of the plough shares may be effected by the rotation of a handle 48, the beam being locked in position by a spring- loaded plunger 49 engaging with holes in stationary blocks 51. The depth of ploughing can be adjusted by rotation of a wheel 60 which alters the inclination to the ground of a link 25 and thus raises or lowers the beam 21. The means for raising and rotating the plough beam and for adjusting the depth of ploughing are readily accessible to the tractor driver.

Title: Circuit arrangement including a discharge lamp
IPC: H05B41/18
Filed: 1976-03-02
Abstract: 1505031 Supply circuits for discharge lamps PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 2 March 1976 [5 March 1975] 08288/76 Heading H2H A supply circuit for a low pressure sodium vapour lamp 10 comprises a first non-saturable coil 3, a second coil 6 which becomes saturated in the operating condition of the lamp and a starter circuit including a semi-conductor switch 22. When an A.C. supply is connected to terminals 1, 2, a capacitor 25 is charged in each half-cycle of the supply via a rectifier bridge 14-17 and a Zener diode 24. The capacitor charges until the breakdown voltage of a device 33 is reached whereupon the transistor switch 22 becomes fully conductive due to the current in a transformer 21. The transistor 22 is then switched off when no further change in current occurs in the transformer 21 and the voltage across a capacitor 12 is increased sufficiently to start the lamp. The fall in the voltage across the lamp when started prevents further operation of the starter circuit. If the lamp refuses to start, a capacitor 37 charges to cause conduction of a transistor 35 which short circuits the capacitor 25 to prevent continued attempts to start the lamp. The circuit also enables restarting of an old lamp and the switch 22 may be a thyristor.

Abstract: 768,019. Combined drum and disc brakes. BENDIX AVIATION CORPORATION. March 23, 1955 [April 8, 1954], No. 8488/55, Class 103 (1). In a combined drum and disc brake, similar to that described in Specification 758,882, pairs of shoes 24 and 22 are arranged to be pivoted independently on anchor members 18 and 20 as a result of the friction drag effect on pads 36 spread apart into engagement with the drum sides 11 and 13 by fluid pressure in cylinders.26 carried by the shoes. If the drum rotation is counterclockwise, as indicated, shoes 24 are engaged directly with the drum by the actuator cylinders integral therewith and such engagement is increased by a thrust through adjustable struts 40 and 42 from shoes 22 which are caused to pivot away from the drum. In the reverse direction of drum rotation the shoes 22 are.engaged directly and the force thereon increased by thrust through struts 40 and 42 from shoes 24. By making the lining 32 on the shoes 24, which may brake forward movement of a vehicle, of greater area than the lining of the shoes 22 for reverse movement, the effective life of the linings may be substantially equalized.

Title: Horizontal and vertical beam deflection control for television receivers
IPC: H04N3/223
Filed: 1963-03-04
Abstract: 994,817. Sawtooth circuits; cathode-ray tube circuits. FERNSEH G.m.b.H. March 4, 1963 [March 3, 1962], No. 8497/63. Headings H3P and H4T. In a deflection circuit for a television receiver, the amplitude of line and field sweeps are simultaneously adjusted by a variable inductor 15, connected across one of the windings of the line output transformer. The field sweep is generated by charging a capacitor 21 from the boosted h.t. supply, hence adjustment of inductor 15 will simultaneously vary the amplitude of both sweeps in proportion. As described, the line deflection circuit comprises a valve 4, regeneratively coupled by an auxiliary winding on the output transformer so as to be self-oscillatory; synchronizing signals being applied via terminal 7. The line deflection waveform is coupled via a winding 14 to the deflection coils 2. An h.t. boosting circuit comprises an efficiency diode 6 and capacitor 12, whilst diodes 9, 10 rectify the flyback pulses across the winding 8 to provide e.h.t. for the cathode-ray tube. The field sweep is provided by charging capacitor 21 from the boosted h.t. supply via resistor 18 and discharging via valve 16, the resulting sawtooth waveform being amplified by valve 20 and coupled via transformer 19 to the field deflection coils 3. It is shown that adjustment of inductor 15 results in compensating variations of both the effective inductance and the rate of change of current in the primary circuit. The effective time constant of the primary circuit is adjusted by variation of resistor 13 so that the energy of the flyback pulses is unchanged in the maximum and minimum settings of inductor 15, hence the e.h.t. voltage is unchanged at these settings and only changes by a maximum of 5% at other settings of inductor 15.

Title: Improvements in/or relating to a process for the manufacture of melamine and the melamine resulting from said process
Filed: 1947-04-01
Abstract: Melamine is made by heating a mixture of urea and an ammonium salt which does not form urea on heating under a positive pressure.  It is preferred that the temperature should be in excess of 250 DEG  C. and the pressure should be in the range between 600 and 5000 pounds per square inch.  Improved results are obtained if the reactants are charged to one of two autoclaves connected in series and the autoclaves heated.  In this way the extraneous matter and the melamine are formed in different vessels.  The preferred ammonium salt is ammonium chloride, but others mentioned are the acetate, sulphate and bromide.  The ammonium salts are present in amounts between 2-10 per cent by weight of the urea employed.  The invention is illustrated by examples.
