Abstract: 857,844. Doors for passenger vehicles. DAIMLER-BENZ A.G. May 13, 1959 [May 13, 1958], No. 16455/59. Addition to 855.619. Class 103(2). The door supporting arm disclosed in the parent Specification is connected to the chassis frame of the vehicle by readily releasable means whereby the arm and door may be removed from the chassis frame. In the embodiment shown in Fig. 2, the arm 6 is mounted in a fixed pivot bearing 7 on the side frame 2 and a bearing comprising a part 25 displaceable by screw means, in a bracket 26 on the frame in the direction of the pivot axis. Resilient members may be provided between the pivots and the bearings. In another embodiment, Fig. 3, a base support plate 27 for a parallelogram linkage carrying a door support arm 8 is securable to the side frame 2 by a wing nut and bolt. A pair of parallelogram linkages may be carried by hinge plates on a base plate securable to the side frame by a bolt having a winged head, as described with reference to Figs. 4 to 7 (not shown). The base plate may have a pair of conical pins engageable in conical sockets in an attachment member mounted on the side frame as described with reference to Figs. 8 to 11 (not shown).

Abstract: 1335325 Workpiece clamping AMSTEDSIEMAG KETTE GmbH 11 April 1972 [21 April 1971 17 July 1971 4 Oct 1971] 16668/72 Addition to 1310072 Heading B3B [Also in Division E2] A clamp comprises a thrust assembly 105 and a thrust pin 116 pivotally engaged at one end with the thrust assembly and at its other end with a rotary actuator 108, the thrust assembly 105 and rotary actuator 108 being arranged coaxially and so that they are axially movable relatively to each other, and the engagements of the thrust pin to both the thrust assembly and the rotary actuator being eccentric with respect to their axes so that rotation of the actuator relative to the thrust assembly moves the thrust pin 116 between a position in which it is skew to the axis and a position in which it extends parallel to the axis and exerts a clamping thrust, the thrust pin 116 or another part through which the clamping thrust is transmitted being compressible against spring loading. A clamping jaw 101 acts against a workpiece 102 and is initially moved by a screwthread drive 104 when the thrust assembly 105 is rotated by turning the rotary actuator 108. At a predetermined torque a spring-biased pin 134 slips from a groove 135 and allows relative rotation between the thrust member and rotary actuator to apply final clamping to the thrust pin 116. The pin 134 can be locked by a rod device 141. In further embodiments the clamp is arranged to be operable in either direction of rotation of the rotary actuator; a rotary vane fluid pressure device is used to rotate the actuator; and the movement caused by the rotation of the thrust pin 116 to an axially parallel position is used to apply traction to a part to be clamped (Fig. 8, not shown). The clamp may be operated electrically, pneumatically or hydraulically and a number of clamps may be connected to a common control circuit.

Title: Improvements in gear-wheel pumps
IPC: F04C15/00
Filed: 1944-09-06
Abstract: 621,612. Gear pumps. PESCO PRODUCTS CO. Sept. 6, 1944, No. 17042. Convention date. Aug. 16, 1943. Addition to 572,967. [Class 110(ii)] A movable bushing forms a side wall bearing against each gear-wheel and has a piston portion against which fluid pressure is exerted. Passages 16 and 17, Fig. 3, act as inlet and outlet conduits respectively or vice-versa, depending on the direction of rotation. Fluid passes by way of one of two ball valves 88 to a chamber 72 and thence through the restricted annular space between a collar 68 and the stem of a metering valve 60 to a chamber 70. The fluid then passes by way of passages 78 to chambers 23, 56 where it exerts pressure on a flange 22 and a piston portion 27 so as to urge the bushing bearing 20 into sealing engagement with a gear-wheel 15. Excess pressure in the chambers 23, 56 is relieved by way of the valve 60, a passage 80 and a ball valve 82 to the inlet conduit 16 or 17. The valve 60 may be of such length that the adjusting screw 74, when screwed fully home, touches it and holds it against its seat 58. Fluid leaking between the gearwheel 15 and the bearing bushing 20 is relieved through a passage 90 into the passages 80. In an alternative construction, Fig. 6, separate spring-loaded pistons 112, 113, in fluid connection with the passages 17, 16 respectively, apply assymetrical loading between a bushing bearing 100 and the gear-wheel 15, the maximum loading pressure occurring approximately over the region of maximum fiuid pressure. A separate metering valve (not shown) for each piston 112, 113, similar to that shown in Fig. 3, is provided. Modified forms of these constructions, in which the metering valves: are omitted, are described.

Patent GB-1121023-A (GB)
Title: Character recognition apparatus
IPC: G06V10/10
Filed: 1966-04-20
Abstract: 1,121,023. Character recognition. INTERNATIONAL BUSINESS MACHINES CORP. 20 April, 1966 [27 April, 1965], No. 17229/66. Heading G4R. Character recognition apparatus comprises means for scanning a character and for recognizing features of said character, means for indicating that part of the character has been displaced and has not been scanned, means for searching for the displaced part, means for scanning said displaced part on discovery and for recognizing the features of the displaced part, and means for combining all the recognized features and producing an output signal repre. senting the complete character. Recognition is based on the slope of the character (discretized to the compass rose points) in particular areas of a 4 x 5 matrix encompassing the character, concurrence of such slope and position features being sometimes required for particular minimum time intervals. The size of the matrix is normalized by a preliminary scan around the character. For the recognition scan, a horizontally-progressing search sawtooth is executed by the scanner (C.R.T.) until a part of the character is encountered, when the outline is followed round. If recognition does not take place, but the features detected suggest that the outline was that of the sickle portion of the number 5, a further search sawtooth is executed to search for the slash of the 5, presumed detached. For this purpose the sawtooth is elevated above the position of the first sawtooth by adding the vertical deflection voltage of the latter on encountering the character to the maximum upwards vertical increment voltage needed in following the outline plus a half volt. If and when encountered, the slash is followed round and recognized by its line endings being positioned in the left-most and right-most columns of the matrix, the line endings being recognized by the rapid change from one slope to the opposite slope. Alternatively, if the slash is encountered before the sickle, this will have happened in the preliminary scan mentioned (for selecting the matrix size), and positive and negative vertical and horizontal maximum excursion voltages used therein and stored will indicate that a slash was encountered (as the " character ") by virtue of the horizontal extension of the shape exceeding the vertical, and the vertical extension being less than a preset amount. These conditions, together with the slash signal from the previous circuitry, set a slash latch. The sickle is then found in the routine search for the next character.
