Title: Torque Sensitive Releasable Servo for a Friction Brake
IPC: F16H63/30
Filed: 1968-12-13
Abstract: 1,190,310. Change speed control; disc brakes; hydraulic brakes. FORD MOTOR CO. Ltd. 13 Dec., 1968 [21 Dec., 1967], No. 59421/68. Headings F2D, F2E and F2F. In an automatic transmission for a motor vehicle wherein an epicyclic gear train provides one ratio (e.g. second ratio) by engagement of a disc brake 741 and another ratio (e.g. direct drive) by engagement of a clutch (34, Fig. 1, not shown), the brake 741 is engaged by pressure liquid supplied from an engine-driven pump to a servo 78 through a control valve 110 mechanically responsive to the reaction torque on the brake. A lost motion spline connection 98 permits limited relative rotation between the servo piston 80<SP>1</SP> and its housing 10<SP>1</SP>. As shown, projections 106, 116 integral with the piston 80<SP>1</SP> co-operate with the supply valve 110 and an exhaust ball valve 118. In the position shown a shift valve 132 supplies pressure liquid through the control valve 110 to the servo chamber 78 and also charges an accumulator 138. During upshift pressure liquid is additionally supplied to the direct-drive clutch (34) and as the clutch takes up drive the reaction torque on the brake servo piston 80<SP>1</SP> reverses to rotate the piston 80<SP>1</SP> clockwise whereupon the projection 106 progressively closes the supply valve 110 and the projection 116 opens the ball valve 118 to exhaust the brake servo 78 through lines 112, 134. When, during downshift, the valve 110 reopens, the brake servo cylinder 78 is rapidly pressurized from the accumulator 138. The reaction torque responsive control of the brake 74<SP>1</SP> may be overridden for engine braking and reverse ratio by moving right a manually operated valve spool 130 to connect the line 122 to the pressure supply whereupon the brake is permanently engaged. In Fig. 6 (not shown) the valves 110, 118 are replaced by an axially slidable valve spool (148) mechanically linked to the brake servo piston and controlling pressure liquid supply and exhaust passages to the servo cylinder.

Title: Apparatus and Process for Measuring the Lost Torque in a Closed Kinematic Chain
IPC: G01L3/14
Filed: 1968-12-13
Abstract: 1,193,039. Dynamometers. CENTRE STEPHANOIS DE RECHERCHES MECANIQUES HYDROMECANIQUE ET FROTTEMENT. Dec. 13, 1968 [Dec. 19, 1967], No.59488/68. Heading G1W. In a system for measuring the torque loss in a kinematic chain (10, 11, 12, 13, 14, 15, 10<SP>1</SP>) the chain is closed upon itself by coupling the coaxial shafts 10, 10<SP>1</SP> to a driving pulley 17 using coupling devices each comprising at least one pair of element 24, 25 in cylinder-piston relationship of which (a) each pair defines a chamber 19 (20, 19<SP>1</SP>, 20<SP>1</SP>) operatively connected with fluid-pressure means 40 (40<SP>1</SP>), 41 (41<SP>1</SP>) and (b) one is rotatable with the pulley 17 and the other with the shaft 10 (10<SP>1</SP>). The hub 23 of the pulley 17 is freely rotatable in the ends of shafts 10, 10<SP>1</SP> and has formed therein two pairs of diametrically opposite cylinders 24, 26; 24<SP>1</SP>, 26<SP>1</SP>; at equal distances from the shafts 10, 10<SP>1</SP>. Rollers 28, 29 carried by an end flange of shaft 10 on spindles 30, 31 are applied against the pistons 25, 27 in the opposite rotational sense to that in which rollers 28<SP>1</SP>, 29<SP>1</SP> are applied against pistons 25<SP>1</SP>, 27<SP>1</SP>. The strokes of the pistons are limited in both directions by abutment of the pistons 25, 27, 25<SP>1</SP>, 271 against shoulders 52, 54, 52<SP>1</SP>, 54<SP>1</SP> and of the rollers 28, 29, 28<SP>1</SP>, 29<SP>1</SP> at 53, 55, 53<SP>1</SP>, 55<SP>1</SP> in recesses 50, 51 in the hub 23. A twisting moment can be introduced into the chain in static conditions by introducing hydraulic pressure into the chambers 19, 20, 19<SP>1</SP>, 20<SP>1</SP>, the pulley assuming a position of neutral equilibrium when the same pressure has been established in each direction. For a dynamic test the pulley 17 is driven by a band and, according to the direction of rotation, two chambers, say 19, 20 increase while 19<SP>1</SP>, 201 decrease in volume, equilibrium being lost while the pressures remain equal due to the torque loss in the chain. The pressure difference required to restore the position of equilibrium with the pulley 17 floating between the abutments of the shafts 10, 10<SP>1</SP> is a measure of the torque loss from which the efficiency of the closed chain can be deduced. The equilibrium position can be detected stroboscopically by means of photoelectric cells. Methods of cancelling out errors due to friction are described involving averaging results of tests carried out successively in opposite directions. In another embodiment Fig. 3 (not shown) the shafts 10, 10<SP>1</SP> are concentric.

Title: Method for centring a solid of revolution and apparatus for  performing the method
IPC: B23Q3/154
Filed: 1970-12-16
Abstract: 1340056 Centring workpieces SKF KUGELLAGERFABRIKEN GmbH 16 Dec 1970 [16 Dec 1969] 59745/70 Heading B3B In a method of centring a cylindrical member to render its longitudinal axis coincident with an axis of rotation about which it is to be machined or tested, the member 1 is held on a chuck 7 which may be magnetic and which is rotatable on a base member 6 which has a clampable vertical stop 10. At right angles to the stop 10 there is provided an adjustable sensing member 3, and the rotation of the member 1 with the chuck repeatedly contacts the sensing member due to any eccentricity between the axes and thus causes member 3 to transmit pulses to an evaluation device 4 which in turn passes signals to a feed mechanism 5 e.g. a gear motor which displaces the member 3 accordingly, until, when concentricity is achieved the pulse signal is continuous and the member 3 is subsequently withdrawn.

Abstract: 1287802 Pipe couplings ZAKO-ROHRVERBINDUNGEN GmbH 8 Dec 1969 [6 Dec 1968 23 June 1969] 59878/69 Heading F2G In a pipe connector, a flared pipe end 14 is held between a flanged serrated conical spigot 13 and two axially spaced pressure surfaces 15, 16 in a conical bore of a holding ring 8, the end flange 12 of the spigot abutting an end face of a connector housing 6 and sealed by an elastic ring 10 in an annular groove in the housing end face. The holding ring 8 screws on to the connector housing 6, and the housing screws into a suitable appliance 19, an elastic sealing ring 3 being provided in a groove in the mating housing end face. For high pressure work, the sealing rings 3, 10 are supported by axially resilient rings 20, 21 of P.T.F.E. or spring steel, Figs. 3-5 (not shown). The gap between the end faces of the spigot 13 and housing 6 outside the sealing ring 10 is less than the inside gap to avoid the sealing ring entering the former gap, due to pressure.
Patent GB-749803-A (GB)
Abstract: 749,803. Theodolites. ZEISS-STIFTUNG, C., [trading as ZEISS, C., [Firm of]]. April 14, 1954 [May 9, 1953], No. 10981/54. Drawings to Specification. Class 97 (2). A theodolite including a telescope rotatable around a vertical and a horizontal axis and having a horizontal circle is characterized in that this circle has in addition to the usual graduations at least one further mark 7 (Fig. 2, not shown) defining a telescope traverse of an angle u such that 1/2 cot u/2 is a whole number n. Preferably the traverse range u of the telescope is subdivided on the horizontal circle by a distance scale determined for a chosen length of cross-staff L used when the method of repeated traversals of the staff is employed. Thus in measuring map distances by p repeated equal traversals α of the cross-staff, the telescope being returned after each such traversal to sight the initial position of the staff by movement together of the telescope and the horizontal circle, the first such traversal indicates on the distance scale the approximate map distance nL while the length #L of the staff read off at the end of the last incomplete traversal required to bring the total traverse to the angle u serves to permit accurate determination of the map distance L/2 cot α/2 where (p+#)α=u. In setting up the cross-staff so that its central perpendicular passes through the vertical axis of the theodolite, known sights mounted on the staff are used and are observed with the theodolite telescope at the middle of its traverse u. For short distances, the map distance is given by the product of the number n and the length of the intercept on the crossstaff during the traverse u, but preferably the telescope and horizontal circle are turned together to set the telescope on the zero end of the staff and the telescope is then traversed to cover the whole length of the staff, the required distance appearing on the distance scale. Thus the scale between zero and the mark 7 gives an approximate map distance at the first traverse for long distances while beyond the mark 7 the scale gives direct readings for short distances.
