Title: Improvements relating to apparatus for interspersing pulses in electrical television video signals
Inventor: WHITE ERIC LAWRENCE CASLING
IPC: H04N5/067
Filed: 1948-09-11
Abstract: 682,159. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Aug. 26, 1949 [Sept. 11, 1948], No. 23915/48. Class 40 (iii). Synchronizing signals are inserted in a television video signal by means of a circuit arrangement comprising two switching devices which are operated alternately and serve to supply to an output impedance device video signals via one switching device and voltage (i.e. synchronizing) pulses via the other switching device. The switching devices comprise two diodes 9 and 13 (Fig. 1) the first (when conducting) supplying video signals (including the D.C. component) from a cathode-follower stage 1 via a diode 6 to the output impedance 10 and the second (when conducting) supplying voltage pulses from a negative voltage source 15 to the impedance 10. In the operation of the circuit the diode 9 (and the diode 6) is rendered non- conducting by the voltage drop which occurs in resistor 7 when a valve 11 is caused to conduct by the application thereto of blanking pulses 20 (Fig. 2) from a source 12, thus reducing to zero (i.e. black level) the video signals developed across 10 after which the diode 13 (which is non- conducting during the initial conduction period of diode 9) is rendered conducting by the voltage rise which occurs at its cathode when diode 16 ceases to conduct due to the potential drop in resistor 18 caused by the conduction of valve 17 when synchronizing pulses 21 (Fig. 2) from source 19 are fed thereto. During the conduction period of diode 13 voltage pulses 22 (Fig. 2), the amplitude of which is determined by the value of resistor 14 and the negative potential source to which this resistor is connected, are developed across resistor 10 and provide the desired synchronizing pulses, the duration of which is that of the pulses 21. When the latter pulses terminate diode 13 is rendered non-conducting and the potential across resistor 10 falls to black level for the remainder of the period of the pulses 20, at the termination of which diodes 6 and 9 are again rendered conducting and so again supply video signals to the resistor 10. A modified circuit, Fig. 3 (not shown), omits diode 6 and substitutes triodes for the diodes 13, 16.

Title: Mass in liquid vehicular crash sensor
IPC: H01H35/14
Filed: 1974-05-30
Abstract: 1435873 Inertia switches BREED CORP 30 May 1974 [4 June 1973] 23972/74 Heading H1N In a vehicle crash sensor for operating a passenger restraint system the inertia mass is a hollow cylinder 5, Fig. 1, mounted in a hollow chamber 1 filled with oil whereby during movement of the cylinder 5 against its return spring 6 the oil flows in the opposite direction, as through orifice 16, at sufficiently high speed to provide inertial damping. The cylinder 5 carries a ring contact 8 inside an insulating bush 7 which is retained in position by washers 11, 12 at a peened over end of the cylinder 5. The contact 8 normally bridges a pair of spring contacts 10 associated with an indicator S for showing circuit continuity. On collision the ring contact moves to bridge normally open contacts 9 associated with an actuator A for the passenger restraint system P. In a modification a small piston 105, Fig. 2, is mounted in the bore of the inertia mass 104 whereby when the mass moves under crash conditions the piston 105 moves in the opposite direction with an amplified movement to close the circuit between contacts 110 controlling the passenger restraint system. The bridging contact 111 carried by the piston 105 is yieldingly restrained by a spring 112 to permit overtravel of the piston 105 to increase contact closure duration.

In the filtration of a liquid such as sugar juice, steam is admitted at 22, Fig. 1. to warm the interior of a casing 10 and filter leaves 13, Fig. 3, arranged horizontally in two tiers. The steam is discharged through individual leaf outlet pipes 16, 16a arranged in a semi-circle. A suspension of diatomaceous earth in, e.g., previously-filtered juice, is now admitted at 24 providing, e.g. 10 lbs. per 100 square feet of filtration area. The filtrate therefrom is discharged into a semi-circular trough 18 arranged on the cover 11 underneath the pipes 16a, and after reception in a selected compartment of a trough 20 is recirculated until clear (by direct observation at 16a). Next, juice to be filtered is introduced at 25 under pressure, and the filtrate received in a second compartment of the trough 20. Thereafter the casing is drained at 27 and hot water is introduced at 23, the "sweet water " being received in the third compartment of the trough 20. The cakes are now removed by pressure water issuing from spray arms 42 rotated by a sluice pipe 39 to which they are attached. Compressed air admitted at 56 maintains the filter cloths 36 flat. After draining the cycle is repeated. Each filter " leaf ", 13, Fig. 3, is constructed for filtration through its upper surface only, being provided with drainage channels 29, 30, (32, now shown) communicating with a sump 31 to which the outlet pipe 16 is connected by a quick-release screw coupling 34. The leaves rest on supports provided on bars 12, 15, secured to the cover 11 so that the cover, outlet pipes, bars and leaf assembly may be lifted as a unit from the casing 10, the bars 12 being guided by flanges 55, Fig. 3, after which any leaf may be removed by uncoupling it from its outlet pipe and sliding it to the right, Fig. 3. In Fig. 9 the leaf assembly is mounted instead on a base 60, and it is the casing 61 which is removable. Liquid to be filtered (or, during sluicing, compressed air) is introduced by two diametrically-opposite pipes 73, each communicating with the lower end of a hollow support member 65a having perforations just above its leaf supports. Pipes 22 to 24 are provided as before. Filtrate is discharged through sight glasses 67 and a swingable gooseneck pipe 68. Rotating spray arms fed at 44 are provided as before.

Title: Improvements in means for controlling aeroplanes
IPC: B64C9/24
Filed: 1930-08-15
Abstract: 360,976. Controlling aeroplanes. PAGE, F. H. and PAGE, Ltd., H., 40, Claremont Road, Cricklewood, London. Aug. 15, 1930, No. 24479. [Class 4.] Wings having ailerons pivoted to their trailing edges are provided with interceptors adapted, when brought into operation, to disturb the air flow over the upper surface of the wing, which interceptors are operable by the ailerons only when the wing approaches the stalling angle, or is stalled. In one form, Figs. 1, 3 and 4 an automatic slat 2 carried by links 4, 5 on the wing 1 is arranged to uncover an interceptor 11 when it moves forwardly at high angles of incidence. The interceptor 11 is pivotally mounted at 12 and is operated by a lever 13 pivoted at 141 on link 5, having a roller 14 on its upper end and connected at its lower end with one end of a cable 15 connected to aileron 3. The roller 14 is normally out of contact with the interceptor, and cable 15 is normally slack to allow of operation of the aileron but is rendered taut by forward movement of the slat and the links 4, 5, Fig. 3, which also brings roller 14 into contact with the interceptor, thereafter upward movement of the aileron causes rotation of lever 13 to raise the interceptor 11 against the resistance of a spring 16<11>. A spring 18 permits unimpeded movement of the aileron beyond that necessary fully to raise the interceptor, and a spring 16 maintains cable 15 in tension at all times in the neighbourhood of the lever and link mechanism of the slat. Fig. 5 shows an application to a wing have a slat mounted on a channel 21 movable in an arcuate path, the lever 13 being mounted on an arm 26 pivoted on the channel 21 and moving forwardly with it as the interceptor is uncovered. A roller 28 on arm 26 engages with a ramp 29 at the end of its travel and thereby rocks the arm 26 and lever 13 upwardly to bring roller 14 into operative position. In a further modification, Fig. 9, lever 13 is mounted on an extension 30 of a lever 31 pivoted co-axially with the link 4 and rotated on forward movement of the slat by means of a pin 33 on link 5 which engages in a slot formed at its upper end. This lever arrangement may be used with either of the constructions previously described. In a further modification the lever 13 is fixed to the wing and forward movement of the slat is utilized to take up slack in cable 15, a link carrying a pulley round which the cable is carried being interconnected with a moving part of the slat mounting. Fig. 12 shows an application of the intention to an unslotted wing, in which an incidence device consisting of a small pivoted aerofoil 40 statically balanced by a counterweight 42 is moved upwardly at large angles of incidence and serves to rotate a lever 45 having a pin 48 engaging in a slot 49 of a rocking lever carrying lever 44. Slot 49 is so shaped that the pin 48 locks the lever 44 at the end of its forward travel until freed again by downward movement of the aerofoil 40. According to a modification a small slat having no considerable slot action may be employed.
