Filed: 1919-03-27
Abstract: 146,571. Selvatico, L. March 27, 1919. Fluid speed indicators.-In speed indicators in which a rotary shaft drives a centrifugal pump which forces liquid into a pressure gauge, the gauge consists of a number of expansible boxes g, Figs. 8 and 9, connected to a lever r pivoted at s and connected by a link h to an arm x fixed to the toothed wheel p gearing with the toothed wheel o on the spring-controlled axle of the pointer n. The graduations may be made practically equal for equal changes of speed by suitably positioning the lever r with respect to the connecting-rod h. The pivot s can be adjusted by adjusting the block w with respect to the fixed piece i, and the downward pressure of the lever r can be adjusted by a set-screw z bearing on a spring v carried by the lever. The pump b takes in liquid at l, Fig. 9, and forces it out along the pipe c except such quantity as may be allowed to escape by the channel E governed by the screw o<1>. The pump and gauge may be adjacent as shown in Figs. 8 and 9 or may be at a distance as shown in Fig. 5 where the pipes h<1>, c<1>, and h<11>, r<1> proceed from the casing of the centrifugal pump and the supply chamber d respectively and pass from the pipe c<1> through the pipes c<11>, f<1> to the gauge, and from the pipe r<1> to liquid in a box d" open to the air by means of a perforated plug d<111>. The box is stated to compensate for changes in the barometric pressure especially when used on aeroplanes, the apparatus being mounted so that the. box d<11> is always at the same vertical distance beneath the pressure gauge and the level of the liquid in the box remains constant. The centrifugal pump may be replaced by the rotary feed-pump of the cooling-water circulation of water-cooled engines of aeroplanes, motor-boats, &c.

Title: Improvements in parachute apparatus
IPC: B64D17/00
Filed: 1925-03-28
Abstract: 251,412. Holt, H. E. S. March 28, 1925. Parachutes.-Spring means for assisting the opening of a parachute comprises one or more spring hoops attached to the parachute fabric and capable of being folded under tension in the form of a figure 8 when the parachute is packed. The invention is described as applied to a pilot parachute, two steel hoops a, b connected together at right angles being used. Alternatively, the two hoops may be formed from a single length of wire. The hoop a is stitched all round to the fabric, but the other hoop b is stitched only to the crown of the parachute and is covered with a fabric diaphragm to prevent the lines from becoming entangled in it. In packing the parachute, by applying pressure with a slight twisting action at the crossing points c, c' both hoops are caused to take the form of a figure 8 as shown in Fig. 4. The four loops thus formed pack flat in the parachute case but retain this form only so long as they are restrained by the cover of the case. The Provisional Specification describes a method of packing the main and pilot parachutes in a container and means for releasing them. An inwardly projecting border of stiff fabric is provided on the container, the main parachute being packed under this border and then covered by a flap. The cover of the container tends to spring open when closed and is released when a number of bolts passing through lugs on the cover and the container are withdrawn by the pull on a lanyard. A slip coupling is provided on the aeronaut's harness for releasing the lanyard as soon as the bolts are withdrawn.

Title: Television transmitting system
IPC: H01J31/48
Filed: 1944-05-03
Abstract: 590,468. Television transmitters. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 3, 1944, No. 8399. Convention date, Aug. 29, 1942. [Classes 39 (i) and 40 (iii)] In a television transmitter in which signals are produced by a low velocity cathode-ray beam scanning a target electrode, negative impulses are applied to the target to reflect the beam entirely during certain periods, for example, during the return strokes following the line and frame scans. This avoids the necessity of suppressing the beam during the return strokes and enables signals to be derived by collecting electrons reflected from the target without having undue modulation of the beam by suppressor signals. The invention is shown as applied to an Orthicon tube in which a low velocity cathode-ray is projected from a cathode 3 towards a target 2 and reflected from the target to an amplifying system including multiplying electrodes 32, 33, 34 and collector anode 35, electrons being subtracted from the reflected beam at the target in accordance with the distribution of charge thereover. The Orthicon tube includes the usual deflecting plates 20, 21 and coils 22, 23 and lift plates 24 serving to effect a separation of the incident and reflected beam as described in Specification 560,904. Negative impulses for preventing subtraction from the beam during the return strokes thereof are applied to'the electrode 6 on the back of the target 2. These impulses are derived from the horizontal or line deflection generator 78 and the vertical or frame deflection generator 82 through amplifiers 90 and 92 which are connected so that the output of 90 is applied to the cathode of 92, the output of 92 being fed to a further amplifier 104 for application to plate 6. The invention may also be applied to Orthicon tubes of the kind described in Specification 543,890.
