Title: Device for switching video signals
IPC: H04N5/268
Filed: 1948-05-12
Abstract: 654,593. Television. DU MONT LABORATORIES, Inc., A. B. May 12, 1948, No. 13067. Convention date, May 13, 1947. [Class 40 (iii)] A switching-device for selecting the video outputs of one or more television pick-up tubes provides means for automatically fading at a predetermined rate from one to the other. Video signals from two television pick-up tubes appear in channels I and II and are applied through cathode-followers 1 and 21 to pentode amplifiers 12 and 33 connected with a common anode load 18. Grid 13 of pentode 12 is connected with a common anode load 18. Grid 13 of pentode 12 is connected through resistancecapacitance network 40, 41, 42, 44, 45 to a source of negative cut-off potential developed across potentiometer 47. Grid 34 of pentode 33 is connected in a similar manner through network 48, 49, 50, 51, 52. With switch 43 closed, grid 13 is returned to earth so that pentodes 12 function normally to amplify the signals appearing in channel I. When the switch is opened, the grid is returned to the negative cut-off potential at a rate determined by the double time-constant network 41, 42, 44, 45 and the signals gradually fade from the output across load 18. On closure of switch 43 the signals reappear at a rate determined by the single time-constant network 41, 42. Switch 53 functions similarly to control stage 33 and is ganged to switch 43 so as to be open when switch 43 is closed. Resistors 42, 45, 50 51 are made variable to control the fade-out and fade-in times and may be ganged. The setting of the negative potential by potentiometer 47 determines the time between the disappearance of one signal and the appearance of the other. When the setting is at the least negative value the signals become mixed as they are switched. The use of a double time-constant network to control the fade-out and a single time-constant circuit to control the fade-in ensures that the rates of disappearance and appearance are nearly equal. The selected signal across load 18 is applied to pentode amplifier 54 and mixed with horizontal synchronizing pulses applied to grid 63 of pentode 64. The combined signal across the common anode load 62 is coupled to stage 74 and an output is derived across the cathode load 76. During the application of each synchronizing pulse, the grid 69 of stage 74 is clamped to a fixed potential, such as earth, by means of a balanced diode clamping circuit, Fig. 1a (not shown), controlled by a blocking oscillator triggered from the synchronizing pulses.

A power steering system comprises a fluid servomotor 20, having an output shaft 22, and a servo valve 14, connected to a high fluid pressure supply from a pump 26 (via a regulating valve 30 and a one-way valve 32) and to a relatively low pressure reservoir 24, for controlling fluid pressure actuation of the servomotor in response to an input torque from a first control shaft 12 operatively connected to a vehicle steering wheel via a second control shaft 40 and is characterized in having another pressure source (accumulator) 34 and means 46 whereby the high fluid pressure supply port of said servo valve 14 is connected to the pressure source 34 when the input control torque, due to a lost motion driving connection in motor 20, exceeds a predetermined value as a result of failure of the first mentioned fluid pressure supply. Shafts 12 and 40 are drivingly connected by a torsionally resilient extension 42 of shaft 40 having balls 51 engaging in two corners of hexagonal extension 44 of shaft 12, see Fig. 3. Means 46 comprises ring 56 having an internal tang 60, Fig. 5, which has electrical contacts 62 and 64 which, upon relative rotation between the shaft 40 and extension 44 of shaft 12 due to twisting of the shaft extension 42, will contact adjacent faces 66 and 68 of shaft 40 to connect contact ring 56 to earth. This energizes a solenoid valve 36 and pressure from fluid pressure reservoir 34 is communicated to control valve 14. A bearing 52 insulates shaft 40 and can be formed of plastics being injected through passages 54 located in the extension 44. The plastics in the passages 54 can act as shear pins such that the arrangement defines a collapsible connection between bar portion 42 and shaft 12 permitting collapse of the steering column in the event of an accident.

Abstract: 1,221,961. Laminated panel; finishing edges of non-metallic sheet material. BROWNLINE CORP. 22 March, 1968 [21 April, 1967], No. 14047/68. Headings B5K and B5N. [Also in Division B8] A pallet formed from a laminated panel comprises a core, e.g. of balsa or plywood, and two facing layers, e.g. of aluminium or phenolic resin, a marginal portion of the panel having been compressed so that the core is thinner and denser in this portion than elsewhere. An edge member extends along the marginal portion. Both faces of the panel may be indented when compressing the marginal portion, Fig. 2, and the edge member may be U-sectioned and metallic and may embrace this portion and be adhered thereto. A tapering transition zone 31 connects the thinner and thicker portions of the panel. Only one surface of the panel may be indented during compression, Fig. 3. This Figure shows an edging strip riveted at 43 to the panel. Two panels of the form shown in Fig. 2, may be joined in edge-to-edge co-planar relation by an H-sectioned member, Fig. 4 (not shown). Alternatively, two such panels may be joined in edge-to-edge relation by a suitably formed member, Fig. 14 (not shown), so that the panels are perpendicular or at any other angle to each other. The panel is compressed, to form the marginal portion of reduced thickness, between two suitably shaped dies Figs. 5, 6, 8, 10 and 11 (not shown). The part of the operative surface of each die which will form the tapered transistion zone may be tapered or rounded so as not to puncture the facing sheets. A block positioned between the dies limits the compressing movement thereof. One of the dies has a planar operative surface if only one face of the laminate is to be indented. The dies may be formed with passages for steam, hot water or electric heating coils in order that local heating of the panel may be effected prior to compression. When an indented portion is required to have a surface parallel to that of the rest of the panel, the corresponding die is shaped so as to effect more compression adjacent the tapering transition zone than at the edge of the panel; on moving the dies apart, the compressed portion expands differentially to give the required parallel surfaces. Alternatively, the dies may be shaped so that the thickness of the compressed portion decreases towards the edge of the panel.
