Title: Improvements in connection with manually operated sun blinds or awnings
IPC: E04F10/06
Filed: 1938-02-07
Abstract: 508,232. Sun blinds. PAGE, A. C. Feb. 7, 1938, No. 3750. [Class 20 (iii)] The members 1,2, 3 of the telescopic supporting arms of a sun blind or awning are locked together, when the blind is fully closed, by a_ device 4 mounted on the member 1. When the blind is moved to its extended position, all three members move outwardly together until the locking device is moved to a releasing position by engaging with a fixed bar 6. The members 2, 3, thus released from the member 1, continue their outward movement and when fully extended are locked together by a locking device 8. This locking device is moved to its unlocking position during the closing movement of the blind by the front end of the member 1. The locking device 4 shown is in the form of a spring-controlled pivoted member having an extension which passes through apertures in the three telescopic members when the blind is fully closed, and an inclined surface 5 adapted to engage with the bar 6. A similar locking device 9, adapted to lock the members 1 and 2 together when the blind is extended, may be mounted on the front end of the member 1. The release of the locking device 9 is also effected by the engagement thereof with the bar 6.

Title: Drive circuit for controlling conduction of a semiconductor device
IPC: H04N3/16
Filed: 1976-01-30
Abstract: 1536186 Semi-conductor switching circuit RCA CORPORATION 30 Jan 1976 [24 Feb 1975] 03791/76 Heading H3T A drive circuit for a semi-conductor device 23 comprises two active current-controlling devices 12, 20, a transformer 16 with a first winding 16a energized by the first device 12 and a second winding 16b to control the conduction of the second device 20, a capacitance 22 coupling the control electrode to the first device 12 to turn off the semi-conductor device in response to one conduction state of the first device and the second device 20 is coupled to the control electrode of 23 to provide current to turn the semi-conductor device 23 on in response to a second conduction state of the first device. Preferably a unidirectional device 15 or 18 is in series with the first or second windings to prevent current flow in the second winding when the first active device 12 is in the first state. The device 23 may be a gate-turn-off SCR or a switching transistor. When the input 10 goes positive capacitor 22 is partially discharged via the transistor 12 and current also flows through the transformer primary. The gate voltage of the GTO 23 falls and quickly removes charge carriers to fast turnoff the GTO. When the input goes negative transistor 12 is turned off, the transformer discharges passing current via the diodes to saturate the second transistor 20, turning 23 on. The circuit could be used in TV horizontal deflection stages.
