Abstract: 612,438. Television receivers. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 22, 1946, No. 8935. Convention date, March 22, 1945. [Class 40 (iii)] [Also in Group XX] In a cabinet for image projection apparatus a viewing screen, coupled to a hinged closure member, has a sliding connection with the cabinet for guiding the screen during closure of said member from viewing position to a position substantially parallel to said member. Images formed on the screen 21 of a cathoderay tube 19 and directed along the optical path 61, 63 by means of a spherical mirror 57 and " correcting plate" 71 are reflected towards a viewing screen 29 by a reflector 27 positioned on the inner surface of a lid 23 which is hinged along an edge 25 of a cabinet 11 such that the reflector 27 makes an angle of 45 degrees with the viewing screen 29 when the latter assumes correct viewing position. A frame 31 carrying the viewing screen and hinged to an edge 35 of lid 23 is fitted with a cam-roller 45 located in a cam slot 41 provided in a plate 43 carried by the side of the cabinet and suitably shaped to control the motion of the viewing screen during opening and closing of the cabinet lid. - A compression spring 37 acting through a link mechanism 39 serves as a counterbalancing mechanism and provides balance and support for the lid in substantially any desired position. Masking elements 47 supported pivotally at each end of the hinge member 35 comprise sector-shaped plates adapted to lie close together and attached to each other by pins 49, 50 moving within slots 51, 52 thus serving to provide the effect of a shadow box for viewing images on the screen 29 as well as to prevent access to the cabinet. When the cabinet lid is closed, the screen 29 is carried to a position substantially parallel to the lid, whilst the masking elements effectively " telescope " together and fit within the upper part of the cabinet. The upper portion of the cabinet may be separated completely from that portion containing high voltage, video and sound apparatus by a suitable sheet of safety glass 91 treated so as to be completely non- reflecting and mounted transversely in the cabinet as shown in Fig. 3. Various components of the receiving apparatus may be mounted on a ledge 15 which pivots outwardly on a hinge 16 to permit of easy adjustment. Specifications 517,428, [Group] XX], and 537,738 are referred to.

Title: Process Control Apparatus
IPC: G05B15/02
Filed: 1967-02-24
Abstract: 1,172,429. Automatic control. E.I. DU PONT DE NEMOURS & CO. Feb. 24, 1967 [March 1, 1966], No.9039/67. Heading G3R. In a system for automatically controlling a process variable, the output of a null-balancing system comparing a variable of the process and a feedback signal is applied to gate pulses from a generator to an actuator which produces the feedback and adjusts the process variable to a predetermined value. In Fig. 1, a signal e a , proportional to the deviation of a process variable from a desired value, is compared at C with a feedback signal e a <SP>1</SP>, and any difference produces a D. C. signal which is applied to logic circuits 10, 11 so that pulses from a source f, are effective to adjust a motorized valve V in the appropriate direction to restore the process variable to the desired value. The pusles are also applied to a digital counter E which feeds a switched-resistance type digital to analogue converter D-A to provide the feedback signal. The converter may have solidstate switching and R. C. damping. The polarity of the signals from comparator C is applied to ensure the correct sense of operation valve V and counter E, and the gain of the feedback loop is varied by manual selection at K 2  of the point at which the pulses are applied to counter E. When a plurality of variables are to be controlled, each is controlled periodically, during successive periods, and the contents of the counter temporarily transferred to a store M in the intervals. An arrangement in which the counter and digital to analogue converter are replaced by a stepping motor operating a potentiometer is described. Modifications are described in which rate of correction is made dependent on the magnitude of the error to provide reset. In one arrangement this is achieved through logic circuits causing greater contents of the feedback counter to select higher frequency outputs from a standard frequency divider so that more pulses are applied to operate the motorized value for larger errors. In another arrangement for the same purpose switches are operated to reset the counter to zero periodically and the pulses required to do so applied to produce a corresponding further operation of the motorized valve in the same direction. In this arrangement signals corresponding to the actual and desired values of the variable may be switched sequentially to the input of the comparator instead of an error signal, and manual adjustment of the desired value arranged to adjust the position of the motorized value simultaneously. Additional digital counters may be used for gain control purposes.
