Title: Recording instrument
IPC: G01D15/24
Filed: 1953-05-08
Abstract: 733,108. Recording-apparatus. BRISTOL CO. May 8, 1953 [May 10, 1952], No. 12973/53. Class .106 (4). A recording device, Fig: 2, wherein a stylus 66 acts on a circular chart 30, freely rotatable on a stationary hub, comprises a constant speed motor 45, Fig. 3, and means 49 operable by the motor for engaging the chart 30 adjacent its periphery and imparting rotation thereto. The motor 45 is mounted on the back of a plate 20 and the drive wheel 49 acts through an opening in the plate 20 on the back of the chart 30,'the chart 30 being pressed against the drive wheel 49 by a spring-loaded wheel 51, Fig. 2. The chart 30 is mounted on a freely rotating collar mounted on a hub on the plate 20. Extending through said hub is a rotatable splined shaft 27 for turning a pointer 35. The pointer 35 is rotatable in a member held by cantilever arms 58 that may be swung away from the chart 30. When said member is swung into engagement with the splined shaft. 27 it is held in engagement therewith by incorporated magnets. At the rear of the plate 20, the axle 67 of the stylus 66 has a gear sector 69 adapted to be moved by a link 72 coupled to an arm 71 extending from a measuring mechanism 70, the measuring mechanism 70 causing angular displacement of the arm 71 in accordance with the value of the measured variable. The gear sector 69 meshes with.a gear 29 to turnthe' pointer 35. Thus, the pointer 35 may indicate the value of the variable at the instant that said value of the variable is being recorded by the stylus 66. Use of the apparatus to cause a variable' quantity to conform to a required time variation. The pointer 35 is replaced by a cam 97, Fig. 4, conforming in shape to the desired recording for the chart 30, and a follower 98 pivoted coaxially with the stylus 66, bears against the cam 97. The cam 97 is rotated at a constant speed by means 77, Fig. 5, or by the motor 45, and the resulting movement of the follower 98 is conveyed by its axle 78 to an arm 79 at the rear of the plate 20. The stylus 66, in this case, acts on the mechanism 70; acting via the arm 71, the link 72 and an arm 74 secured to the axle 73 of the stylus 66. Co-operatively mounted on the arms 74 and 79 respectively are the elements 80 and 81 of a control. couple adapted to coact with auxiliary apparatus to regulate the magnitude of the measured variable according to the relative position of the elements. Thus the stylus 66 will tend to produce a recording simulating the shape of the cam 97 and the variable quantity, which is governed by the mechanism 70, varies accordingly. Specifications 380,659, [Group XXIX],. and 539,864, [Group XXXV], are referred to.

Title: Improvements in or relating to valves
IPC: B60T11/34
Filed: 1966-03-24
Abstract: 1,116,051. Fluid-pressure brakes; valves. H. TEVES, E. A. TEVES, and M. TAUSEND, [trading as ALFRED TEVES MASCHINENUND ARMATURENFABRIK KOMM. GES.]. 24 March, 1966 [15 Sept., 1965], No. 13037/66. Headings F2F and F2V. In a valve assembly for insertion in the line between the master cylinder and the front wheel disc brake cylinders to delay the application of the front wheel disc brakes, a piston 10 is disposed in a cylindrical chamber 3 and is loaded on one side by a spring 11 such that it can move against the force of the spring as far as an annular stop formed by a plug member 12, on the other side of the piston there is a push rod 13 which is associated with and guided by a ball valve arrangement 14-18 controlling the flow of brake fluid from the master cylinder to the wheel brake cylinder to keep the valve open when the brake is off. The ball valve comprises a spring-loaded ball 15, a valve seat 14 formed with projections 14a and guided in a chamber 4 of larger diameter than the chamber 3 and an annular disc 17 is disposed on a shoulder 13a of the piston push rod 13, the push rod passing through a slotted bush 16 which is forced by a weaker spring 18 against the valve seat 14. When the brake is in its operative position the parts of the valve are in the position shown in Fig. 1 wherein the push rod 13 of the piston 10 keeps the ball 15 of the ball valve in its open position so that there is unpressurized connection between the master cylinder and the wheel brake cylinder. When the brake is applied, the master cylinder supplies brake fluid to the wheel brake cylinders via a port 6, open ball valve 15, and apertures in the slotted bush 16 to the front wheel brake cylinders via connection 7. As the brake back pressure builds up, the piston 10 is moved against its spring 11 and the ball valve closes to prevent further flow to the front wheel brake cylinders. When the pressure of the brake fluid supplied by the master cylinder to chamber 4 rises further the valve seat 14 with the ball 15 disengages from its seat and moves against the force of the spring 18, brake fluid being then able to flow via the projections 14a and slotted bush 16 to the front wheel brake cylinders so that the brakes are applied with delay.

Title: Improvements relating to Tractor Ploughs.
Inventor: FERGUSON HARRY
IPC: A01B3/38
Filed: 1917-09-12
Abstract: 119,883. Ferguson, H. Sept. 12, 1917. Ploughs. - The connexion between a plough frame and a tractor is arranged to give the usual vertical and lateral movement of the plough relatively to the tractor and also permits of the plough being canted when so desired. In the form shown, the plough a is provided with a forked head a<1> connected by a pivotal safety-pin a<2> to a frog b<18> adjustably mounted on a pin b<13> supported at its ends by universal joints in crank-arms b<11>, b<12>. These crank-arms are carried by a shaft b<10>, the arm b<11> being rigidly secured to this shaft and the arm b<12> loosely mounted thereon but provided with a rearwardly extending portion b<15>. The shaft b<10> is carried in arms b<8> secured to a rock-shaft b<9> operated by the hand-lever b<1>. By moving the rockshaft through the lever b', the crankarms b<11>, b<12> are lifted to raise the front of the plough, the arm b<12> being prevented trom swinging round the shaft b<10> by the extension b<15> engaging the end of the shaft b<9>. A considerable movement of the lever b<1> causes the extreme ends of the crank-arms to engage stops a<3> on the plough frame, thus lifting the frame bodily about the axis b<9>. A canting movement to the plough frame is given by adjusting a stop b" operated by a hand-lever b<2> to engage the extension b<15> of the loose crank-arm b<12>. In a modification, both the crank-arms are rigidly secured to their operating shaft, but the pin on which the universal joint of the plough frame is secured is provided at its ends with eccentric mountings so that, by rotating the pin, one side of the plough may be depressed relatively to the other. In this modification, a flat spring is provided to check excessive lateral swinging of the plough, and lift of the rear end of the plough frame is obtained by a rod loosely secured to the tractor and to the rear of the plough frame and adapted to pivot, as the front of the plough is raised, on a projection on the front of the plough, thus raising the rear end of the plough.

[Also in Division G3] In a hydrant, a pressure-responsive control valve 19, 20 admits the high pressure supply to the working space 11 of a hydraulic valve actuator 7 when the outlet pressure rises above a pre-set limit to cause the valve member 5 to move towards its closed position. The pressure in outlet 10 is communicated through passage 124 to act on spring-loaded piston 24 which, at the pre-set pressure, closes valve 19 and opens valve 20. The high pressure in inlet 9 is communicated through passage 22, chamber 21, valve 20, passages 18, 17, 14, 13 and 12 to space 11. If the outlet pressure falls below the pre-set limit valve 20 is closed and valve 19 opened and the outlet pressure is communicated through passages 124, 23, 18, 17, 14, 12, 13 to space 11. Valve 5 is moved to seek an equilibrium position which controls the outlet pressure. The control valve 19, 20 may communicate with the high pressure supply through an external pipe. The space 11 may be connected to the control valve 19, 20 through a flexible pipe inside the casing 3.

Alternatively, a single output transformer with two symmetrical but phase-reversing half-portions, each including the emitter/collector path of a transistor, may be used, the transistors being rendered conductive alternately, with phase reversal, through each half of the output transformer. The transistors may be symmetrical or, if not, the transformer winding turns being proportionately arranged to balance the different emitter and collector currents.
