Abstract: ABSTRACT There is provided an apparatus for withdrawing a liquid from a container, specifically oil from the crank-case of an engine.  A rigid, fluid-tight receptacle has a circular top wall and an upstanding rim at the periphery thereof.  From the receptacle a vacuum line extends, for connection to a source of vacuum, and the vacuum line has a check valve for preventing backflow of gas.  An elongated flexible probe is provided for insertion into the con-tainer to take up the liquid, and a conduit extends from the receptacle to the probe, which conduit is divided into two portions.  The first portion extends from the receptacle to a control valve, while the second section has its one end connected to the probe and has its other end adapted for selective attachment to and detachment from the control valve.  The second portion of the suction conduit has an inside diameter large enough to receive the flexible probe, and has a length substantially equal to the inner circumference of the rim. In this manner, the probe can be inserted fully into said other end of the second portion of the suction conduit, and then the latter can be lodged in circular configuration inside and against the rim for purposes of storage and transport. The probe, which is a sensitive and delicate part of the apparatus, is thus doubly protected.  Firstly it is protected by being within the conduit itself, and secondly it is lodged permanently within a rigid rim of the receptacle, along with the conduit itself, thereby preventing accidental knocks, pinching, etc.

Abstract: ABSTRACT            A cylinder lock-key combination includes a cylinder housing (1) having arranged therein a rotatable cylinder plug (2) having a slot (3) for a key (8). Arranged on the spine of the key is coded information in the form of regions (8a, 8b) of mutually different magnetic permeabi-lity. When the key moves relative to the housing these regions cause variations in a magnetic flux generated by a magnetic body (5k) and passing the key slot (3). A differential field plate (5) arranged in the housing and incorporated in an electric circuit , which also incorporates a bridge coupling, is arranged to convert said magnetic flux variations to momentary changes in resistance in the electric circuit, causing the bridge coupling to become unbalanced so that an electric pulse train corresponding to the coded information is generated in the circuit. This pulse train is sensed and evaluated by means, for example, of a data processing device. The invention also relates to a cylinder lock and a key for said combination.            (Figure 1).

Abstract: THERMALLY ADDRESSED CHOLESTERIC-SMECTIC LIQUID CRYSTAL DEVICE           ABSTRACT OF THE DISCLOSURE          A visual display device as shown in Figure 1 is featured which uses a new thermal addressing technique to provide a dark image upon a lighter background.  The display is capable of being multiplexed to a large number of rows.  The device comprises a cholesteric-smectic liquid crystal material mixed with a pleochroic dye of high order parameter.  When the material experiences a transition from a higher to a lower, smectic thermal phase, two different textures or light states are developed; a transparent state and a light absorbing state.  The transparent state is developed by applying a sensitizing voltage to certain portions of the medium.  The pleochroic dye absorbs the light passing through the unsensitized portions of medium to provide the dark image.  The row electrodes are made diffusely reflective so as to provide a double light pass through the medium to improve contrast.
