Abstract: 所接收的经MPEG编码和压缩的图像信号经解压缩后送至显示器。在将运动补偿所需的帧存入存储器(14)前，通过量化(20)DPCM预测误差值(18)对像素块重新进行压缩以降低对带宽和帧存储器的要求。固定长度的量化和解量化表(图2)具有N层(例如为15层)，每层具有一个对应的占优势的M比特(例如为4比特)的输出码元，除了所述N层中的至少一层(例如层7)由一个具有少于M比特(例如为3比特)的唯一短码元限定。可以将M比特中的一个比特保留为符号比特。每当使用一个短码元表示一个数据值时，就缩减和/或节约了带宽和存储器留作他用，例如将开销数据插入固定长度数据流。对于诸如图像数据之类的大数据序列，存储器和带宽的缩减就非常明显。

Abstract: The vertically movable door has a flexible door plate, a hoist mechanism for lifting and lowering the door plate and a lower beam, which is attached with suspension members, such as hoist lines (34), to the hoist mechanism. In the edges of the door plate there are side rails guiding the vertical movement of the door plate. The vertically movable door has a safety catch, which has a protruding locking cam (56), which attaches to the side rail. The safety catch prevents the uncontrolled falling of the vertically movable door due for example to the breaking of the suspension member. The safety catch comprises a catch plate (30), wherein said locking cam is formed, a turning axis (32) for attaching the catch plate in a rotating manner to the lower beam of the vertically movable door and attaching members for attaching the hoist line to the catch plate. The catch plate is arranged to rotate into a locking position, where the locking cam is pushed up, when the tension force of the suspension member attached thereto falls below a predetermined value. Correspondingly the catch plate is arranged to remain in a standby position, where the locking cam is not protruding, when the tension force of the suspension member attached thereto exceeds the predetermined value. The locking cam is arranged to protrude from the vertical edge of the door plate in the direction of the tangent of the door plate. The side rails comprise a catch rail (60), which has locking holes (70) for receiving the locking cam.

Abstract: 1,054,950. Rotary wing aircraft. ELTRA CORPORATION. Dec. 3, 1963 [Dec. 10, 1962], No. 47791/63. Headings B7G and B7W. In a rotary wing aircraft having a fuselage section 25, a normally horizontal platform defining frame structure is provided integral with the aircraft, a plurality of struts connect said frame structure and fuselage section for supporting the latter in a flight-ready condition in spaced relationship above said frame structure to define a compartment 27 therewith, the struts allowing a selective downward movement of said fuselage section into a collapsed condition; and a releasable fastener structure for constraining said fuselage section in the flightready position. As shown, the fuselage section is supported above the frame or floor of the helicopter by tubular struts 72a, 73a, 74a which are pivoted at their lower ends to frame element 61 and at their upper ends to the fuselage 25. Strut 73a is releasably connected to the fuselage by a quick release pin 80a. In order to nest the fuselage in the frame structure (Fig. 16, not shown) cables 44, 52 (Fig. 17, not shown) are passed under the pulley wheels 39, 40 and winch 51 is operated such that the cables support the fuselage which permits the removal of pins 80. Cables 44, 52 are further shortened which displaces the fuselage forwardly until struts 72, 74 are vertically disposed. The fuselage is held momentarily in this position and winch 51 is rotated slightly to provide slack in cables 44, 52. The fuselage is then shifted forwardly to permit it to descend into its fully folded position (Fig. 16, not shown). The aircraft is further provided with selectively retractable landing gear 28 and two fulcrum supports about which the aircraft is rocked to relieve the landing gear of its aircraft support function (Figs. 7 to 13, not shown). The compartment includes cargo space and pilot's cabin equipped with seat and flight control components selectively movable into retracted positions to accommodate the fuselage section when it is in the collapsed state. The tail boom 26 may be removed either before or after the fuselage is nested by releasing fasteners 117, removing pin 130 (Fig. 18, not shown) and displacing sleeve 124 rearwardly to withdraw it from shaft 120. Fig. 19 (not shown) illustrates a method of attaching the pivot wheels 84 to the frame elements 61, 70. The aircraft may be converted into an aerial crane by swinging away platform sections 95, 96 (Fig. 5, not shown) and suspending a cable through the opening thus formed. The cable or a winch may be secured to the fuselage section 25 by hook 140. The rotor blades may be removed, or folded and held to the boom by a strap 139 and hook 138 (Fig. 2, not shown).

Abstract: 1,225,327. Two-part couplings. BELLING & LEE Ltd. 12 May, 1969, No. 24127/69. Heading H2E. A contact member assembly comprises an axially symmetrical conductive contact member 1 having a contact portion 2 and a portion 4 of reduced diameter on which is closely fitted a resilient insulating sleeve member 7, e.g. of nylon, which is of longitudinally split tubular form, to facilitate the fitting of the sleeve in position by deformation. A flange portion 9 on the sleeve extending radially beyond the contact member 1 provides means for axial location of the assembly in an aperture in an insulating board (Fig. 3, not shown) and may also serve to guide the indentors 13, 14 of a crimping tool while making an electrical connection to terminal 5. The extent of the said longitudinal opening is determined by the resilience of the sleeve material. The assembly may be located free of axial movement in either direction by fastening with the first insulating board a second board having a counterbored aperture to receive the flange portion 9. A modification has the sleeve with its flange portion intermediate between the ends and a second modification has the entire length of the insulating sleeve projecting radially to form the flange.
