Title: Method of heating or cooling a glass sheet
IPC: C03B27/008
Filed: 1962-09-19
Abstract: A glass sheet is heated or cooled by a gas flowing in contact therewith, the gas passing between the sheet and a closely-adjacent body so as to provide a flow along a portion of the glass surface which is spaced from the body a distance of 0.001 to 0.1 inch, preferably 0.003 to 0.05 inch.  The sheet is conveyed between upper and lower streams of gas emitted from bodies constituting open-ended chambers, the lower stream being sufficiently strong to counter-balance the weight of the sheet and the pressure of the upper stream and support the sheet out of contact with the body.  The apparatus and methods of use are described in Specifications 1,021,841, 1,021,842, 1,021,843, 1,021,845, 1,021,846, 1,021,847 and 1,021,852.

Lubricant conveyed by fluid.- A mixture of lubricant and air is supplied to a part to be lubricated by a pump communicating directly therewith, the pump being so diminished relative to the delivery pipe that the mixture is delivered as a jet upon the part to be lubricated at a predetermined moment when the delivery orifice is in register with the part. The pump has no delivery valve.

Abstract: 897,768. Fluid-pressure servomotor-control systems. GERMANE CORPORATION. Oct. 23, 1959 [Nov. 25, 1958], No. 36020/59. Class 135. [Also in Group XXXI] In a controller for a fluid - pressure - operated device, e.g. a vehicle steering-gear 19, Fig. 1, actuated by piston 14, turning of wheel 37 rotates a primary sleeve valve 31, Figs. 3, 5, against leaf - springs 45, valve 31 having a lost motion connection with a rotary follow-up sleeve valve 32, Figs. 3, 6, sliding around valve 31 via a pin 42 carried by valve 32. Valve 32 is connected by eccentrically moving link 72 embracing pin 42 at one end and having a splined ball-joint 73 at the other end, with a toothed rotor 67, Figs. 3, 7, movable by fluid pressure in an epicycle within a toothed casing 24 and forming expanding or contracting chambers 70 therewith. Pump P supplies pressure fluid to an inlet 3 of controller casing 2 which has an exhaust 8 and two motor ports 10, 11 to the piston 14. On rotation of valve 31 from a neutral position, in which fluid is locked in cylinder 14 and in the epicyclic device 24 and is circulated by pump P through passages in the valve sleeves, pressure fluid from pump P passes through inlet 3, passages 62, Fig. 6, channel 49, recesses 51, Figs. 3, 5, passages 63, Fig. 6, and passages 71, Fig. 3, to expand certain chambers 70 of the epicyclic device. Other chambers 70 contract and fluid is forced through other passages 71, 63 to grooves 54, Fig. 5, passages 65, Fig. 6, and port 11 to actuate piston 14. While fluid from the exhaust side of the piston returns through port 10, passages 58, 64, Figs. 3, 6, passages 55, Fig. 5, passages 33, 52, Fig. 3, and 66, Fig. 6, to exhaust 8. As fluid flows into one side of the piston, an equal amount of fluid flows through the epicyclic device and the rotor recentres the follow-up sleeve with the primary sleeve valve. Should pump P fail, rotation of hand wheel 37 takes up the lost motion at pin 42 and through the sleeves 31, 32 and link 72, turns the rotor 67 so that the epicyclic device acts as a hand pump for moving piston ]4. Specification 787,499 is referred to.

Title: Improvements in and connected with vehicle steering mechanism for multi-wheel steering
IPC: B62D7/15
Filed: 1938-12-12
Abstract: 511,120. Motor-vehicle steering-gear. DAIMLER-BENZ AKT.-GES. Dec. 12, 1938, No. 36191. Convention date, Aug. 13. [Class 79 (v)] In vehicles having more than one pair of wheels steered some of the wheels being connectable to and disconnectable from the steering gear, an axially-movable toothed gear can be moved into mesh with a toothed gear of the steering mechanism or out of mesh to a position in which it is locked against rotation. In the construction shown a link m connected to the steering means for the front wheels and therefore permanently connected to the steering gear, is connected to an arm k on, a shaft f having a toothed sector n normally in mesh with a sector o slidably-keyed on a shaft e connected by an arm g and a link i to the steering means for the rear wheels. Thus, when the front wheels are steered and the sectors n, o are in mesh the rear wheels are steered in the opposite direction. In order to disconnect the rear wheels from the steering gear and to lock them against steering movement the sector o is slid along its shaft e until it is out of engagement with the sector n, and clutch teeth r on the sector n engage fixed teeth s on the gear casing b fixed to the frame. This is effected by the driver by means of a rod v<2>, spring wand lever u, p acting on the sector o. Axial movement of the sector is possible only when the steering gear is in the straight-ahead position; for this purpose the sector n is provided with a shroud plate x having an opening z which permits the axial movement of the sector o only in the position shown in Fig. 2. The spring w, in the rod v<2> allows the rod to be moved to either the steering or locking position irrespective of the position of the steering gear, if the sector n is not in the position shown the sector o will not move but the spring w will be compressed. Then, as soon as the steering gear is moved to the straight-ahead position and the sector n to the position shown the sector o is moved by the spring w to the position required.

Title: Chuck for a machine tool
IPC: B23B31/28
Filed: 1966-08-16
Abstract: 1,144,580. Chucks. H. GIRAUD, and V. MARTIN. 16 Aug., 1966 [13 Sept., 1965], No. 36578/66. Headings B3B and B3T. A chuck, e.g. for a lathe is provided with a reversible motor which may be connected by a coupling to a planetary differential gear unit to effect radial adjustment of the jaws of the chuck. When the chuck jaws are to be adjusted to grip or release a workpiece the normal rotary drive to the chuck which is transmitted through a hollow spindle 6 is stopped and a reversible motor 7 is connected through an electromagnetic powdertype coupling 9 to a sun-wheel 10 of a first group of planetary pinions 13 causing orbital rotation thereof since they are in mesh with an internal gear 15 connected to the stationary spindle 6. Corresponding orbital movement occurs, of a second group of planetary pinions 14 which are smaller than and connected to pinions 13 and which mesh with an internal gear 17 connected to the end of a hollow shaft 19 which thereby rotates at reduced speed. Shaft 19 passes through the hollow spindle 6 and carries at its end adjacent the chuck a sun-wheel 21, rotation of which causes rotation about their own axes of a third group of planet wheels 22 which in turn cause rotation of internal gear 23 connected to a rotatable scroll member 24 which engages teeth on the chuck jaws 4. The latter are thereby adjusted radially inwards or outwards according to the direction of rotation of reversible motor 7. The gripping pressure of the jaws 4 on a workpiece is determined by the coupling 9 which acts to disconnect the drive from motor 7 at a preselected torque. Alternatively the motor 7 may be of a variable torque type. For normal drive of the chuck and workpiece sun-wheel 10 is disconnected from the motor 7, hollow spindle 6 is rotated by external drive means and the entire train comprising sun-wheel 10, planet wheels 13, 14, shaft 19, sun-wheel 21, planet wheels 22, internal gear 23 and chuck 3 all rotate with and at the same speed as spindle 6.
