Title: Cathode ray tube control circuit
IPC: H03K4/86
Filed: 1944-09-15
Abstract: 586,649. Saw-tooth generating circuits. ; NEWTON, E. P. (Standard Oil Co. of California). Sept. 15, 1944, No. 17724. [Class 40 (v)] [Also in Group XXXVIII] In a time base circuit for a cathode ray tube, a pulse fires a gas-filled valve having a condenser in the anode circuit, a gas filled diode firing after a delay and through differentiating means causing a second gas-filled valve to fire to generate the time base. The anode resistances of the two gas-filled valves are mechanically ganged so that the delay and duration of the time base sweep are varied together. The signal from a pick-up unit 10 amplified by pentode 15 is applied to an integrating circuit 20, 21 feeding a triode amplifier 23. The signal from valve 23 fires the gas-filled valve 29 discharging condenser 33, the anode potential falling until the valve is extinguished. Condenser 33 charges over resistances 35, 36, the neon tube 34 firing when the potential reaches the ionization value, causing a positive pulse to appear across resistance A. The pulse, differentiated by condenser 37 and resistance 38, fires gas-filled triode 40 discharging condenser 44 and then extinguishing when the anode potential falls below the ionization value. Condenser 44 charges over resistances 45, 46 to generate the time base sweep. By ganging resistances 36, 46 the delay and , duration of the time base sweep are varied simultaneously. U.S.A. Specification 2,269,760-is referred to.

Patent GB-1421020-A (GB)
Title: Scanning apparatus heat exchangers
IPC: G03B27/50
Filed: 1973-04-16
Abstract: 1421020 Scanning apparatus VAN DYK RESEARCH CORP 16 April 1973 [26 April 1972] 18167/73 Heading G2A A scanning apparatus has a scanning mirror on a rotatable shaft which is driven by a first motor in the scanning direction, and by a second motor in the reverse direction, the angular velocity in the said reverse direction being limited to a predetermined maximum value. As shown, the mirror 16 pivots on a shaft 36 to scan a document 14 laid on a curved transparent support plate 15, from the initial "rest" position 45 to the maximum scan position 46. The reflected light from the scanned document passes through a lens 17 and is reflected from a fixed mirror 18 through a slot aperture 19 on to a rotating drum 11 having on its outer surface a coating of a photo-conductive material. This is part of a xerographic copying apparatus seen in more detail in Fig. 1 (not shown). The mirror is biased into the rest position by a spring 37. A drive motor 41 is coupled to the shaft 36 through a clutch 42 which is engaged when the document is to be scanned, and disengaged by a control signal at the end of the scanning sweep. The return spring 37 accelerates the mirror, on its return movement, to a high angular velocity so that when it comes up against a stop 38 the components are subjected to a considerable amount of shock and vibration. In order to reduce this, the return movement of the mirror is controlled by a second motor 47 and clutch 48. Motor 47 and its shaft 49 rotate at a constant predetermined angular velocity. If the angular velocity of the mirror on its return movement exceeds this constant value, clutch 48 is engaged, so that the mirror's velocity is reduced to that of shaft 49. The mechanism arrangement which produces the above effects is seen in more detail in Fig.3 (not shown), and a linkage member (63) in this mechaanism has the effect of causing angular velocity of shaft 36 to be further reduced to almost zero as the mirror approaches its rest position.
