Abstract: 959,579. Steering trailers. HARRISON, McGREGOR & GUEST Ltd. Nov. 21, 1961 [Nov. 21, 1960], No. 39875/60. Heading B7H. A trailed vehicle, e.g. an agricultural machine, is towed by a tractor by means of a towing bar 17 pivoted about a horizontal axis to brackets 23 and adjustable in height by means of a screw jack or a piston and cylinder 24, whereby the working height of the machine can be adjusted. Apparatus on the trailer is driven from the tractor through a cardan shaft 29 and an input shaft 38 in line with a vertical hitch pin by means of which the shaft 17 is connected to the tractor. The vehicle wheels are carried by brackets 31 mounted on king pins 32, a lever 38 being connected to each bracket and pivoted to an adjustable track rod 33 for simultaneous movement of the wheels. The track rod can be secured in each of two positions, wherein the wheels occupy the positions shown in full and broken lines, by the engagement of a plunger with one or other of two holes 39 and 40 provided in a flattened portion of the track rod. The plunger is spring-loaded and operated by the driver of the tractor through a cord 47 and a bell-crank lever. The arrangement provides that the vehicle can occupy each of two trailed positions, immediately behind the tractor and offset to one side, according to the position of the wheels, the position being selected according to which hole 39 or 40 is engaged by the plunger, the plunger and required hole being brought into register by driving the tractor forward or backward as the case may be.

Abstract: 844,975. Tuning system for frequency synthesizers. COLLINS RADIO CO. Dec. 23, 1957 [April 24, 1957], No. 39938/57. Class 40(6). In a tuning means for a frequency synthesizer the pass band of the filters in the digital units thereof are varied by adjustable capacitances coupled to the tuning shaft of the unit, and also, with the exception of the first digital unit, by other adjustable capacitances coupled to the tuning shaft of the prior adjacent unit. In the embodiment shown in Fig. 1, the filters for digital unit B comprise L<SP>1</SP> 1 , C<SP>1</SP> s1 , C<SP>1</SP> p1 , and #C<SP>1</SP> p1  for the first filter, and L<SP>1</SP> 2 , C<SP>2</SP> s2 , C<SP>1</SP> p2 , and #C<SP>1</SP> p2  for the second filter. The tuning shaft 23b adjusts the values of C<SP>1</SP> s1 , C<SP>1</SP> s2 , C<SP>1</SP> p1 , C<SP>1</SP> p2  and the tuning shaft 23a in the prior adjacent digital unit A adjusts #C<SP>1</SP> p1  and #C<SP>1</SP> p2 . Equations are given for the determination of values of C p  and C s  such that the second order changes in frequency due to changes in #C p  are linear. The capacitance may be variable or alternatively banks of fixed capacitors (Fig. 3 not shown) connected to single pole switches may be used, the poles of the switches being coupled to the tuning shaft. The first digital unit 16a may comprise a harmonic selector switch 18a frequency divider 17a a filter 14 and the incremental capacitors for the unit 16b as shown, or alternatively (Fig. 2 not shown) it may contain a variable oscillator and the said incremental capacitors.

Abstract: 943,395. Change-speed control. FORD MOTOR CO. Ltd. Oct. 23, 1962 [Dec. 4, 1961], No. 40034/62. Heading F2D. A hand - operated change - speed lever 72, Fig. 6, carries at its lower end a part-ball-shaped connector 80, Figs. 4, 7, engaging the inner walls 34, 36 of a bracket 26 over which it rolls for axially sliding of a selector shaft 40 pivoted to the connector by a pin 68, axial movement of the selector shaft engaging a clutch pin 60 carried thereby in one or other of slotted recesses 46, 48, 50 in selector levers 14, 16, 18 mounted upon the selector shaft, actuation of the change-speed lever to rotate the selector shafts then turning the desired lever for ratio establishment. The selector levers 14, 16, 18 are connected by links 45, 47, 49, Figs. 1, 11, to levers 141, 16<1>, 18<1> turned to establish reverse; first and second ratios; third and fourth ratios, respectively, in a motor car transmission. An interlock 105 inhibits movement of either of the selector levers 14, 16 to a ratio established position while the other lever is in a corresponding ratio established position, and a spring-biased ball detent 107 acts on the reverse lever 14<1>. The arrangement is such that the selector levers 14, 16, 18 must all be returned to their neutral positions before the clutch pin 60 on the selector shaft 40 can be slidden from one to the other of the recesses 46, 48, 50 and a further ratio established. A spring 56, Fig. 7, biases the selector shaft 40 in a direction to engage the clutch pin 60 in the recess 50 of the third-fourth selector lever 18. Sliding of the selector shaft 40 to engage the reverse selector lever 14 is normally prevented by a tab 94, Figs. 4, 7, on a slider 86 within the change-speed lever 72, engaging the wall 34 of the bracket 26. To establish reverse, a trigger 100, Fig. 6, adjacent a knob 85 on the change-speed lever 72, is pulled, a cable within the change-speed lever then acting against the bias of a spring 88 to pull the slider 86 upwardly, so that the tab 94 can enter a hole 106, Fig. 7, in the bracket wall 30, thus enabling the change-speed lever to pivot sufficiently far to slide the selector shaft 40 and engage the clutch pin 60 with the recess 46 in the reverse selector lever 14. The shiftpattern followed by the change-speed lever 72 is indicated upon the knob 85, Fig. 10 (not shown).

Filed: 1973-08-28
Abstract: 1426236 N M R gyrometers  COMMISSARIAT A L'ENERGIE ATOMIQUE 28 Aug 1973 [20 Sept 1972] 40547/73 Heading G1N The invention relates to an N.M.R. gyrometer of the type wherein the rotation (to be measured) is parallel to the directing field, so that the Larmor frequency of a magnetometer mounted at right angles to the field is increased by the angular velocity, which is then determined by comparison with a reference oscillator. Instead of using an external reference oscillator as heretofore, the reference is provided by the actual Larmor frequency derived from a SECOND N.M.R. MAGNETOMETER mounted parallel to the rotational axis (and directing field). The magnetometers may be of the kind using two coils with different samples connected as a spin-coupled oscillator, as described in detail in Specification 1341865, and illustrated here in Figs. 1 and 2 (not shown). In an alternative construction Fig. 3 a single magnetometer of this type mounted on the spin axis Z is coupled to coils 42, 42' mounted on the X-axis to pick off the signal with the velocity component. This is compared at 46 with the Larmor frequency from amplifier 20 driving the  coils 6, 6 of the spin-coupled'oscillator/ magnetometer.  Field control. The Larmor frequency from amplifier 20 is also compared at 50 with a reference frequency from oscillator 52. Any drift indicates field variation and the error signal is used to control a regulating-winding 41 supplementing the main-field-winding 40.

Electrically conductive continuous strand material is fed continuously into and out of contact with a covering of absorbent insulating material on a continuously moving conductive surface which is at least partly immersed in a conductive treatment bath and an electric current is supplied to the strand material through the absorbent covering to perform a required electrolytic coating or other treatment of one surface of the strand. Either the strand is caused to enter and pass through the treatment bath in contact with the insulating covering or it is caused to travel in contact with the covering on a part of the moving conductive surface projecting outwardly from the treatment bath.  The continuous strand may move at the same speed as or at a different speed from the moving conductive surface and the electrolytic treatment may comprise deposition a coating of a metal or alloy, a metal oxide or a non-metallic material, production of a conversion coating or cleaning. As shown a metal strip 1 connected to earth is fed in succession over drums 2, 3 connected to negative and positive poles respectively of a D.C. source and dipping into alkali cleaning and metal plating baths 4, 5, the drums being covered with viscosebonded rayon fibre material or a pile fabric of nylon or polyethylene terephthalate fibre.
