The diverging sides include an angle of from 13 to 16 degrees, and the trapezium may be further modified by making one of the non-diverging sides of arcuate form to fit a round headlamp. In one embodiment the sheet is printed black all over except for guide lines delineating one or more areas of the required shape, the user cutting the required shape from the sheet to suit his particular type of headlamp. In a second embodiment the sheet is designed to fit a particular type of headlamp and the opaque area, which alone carries the adhesive, is surrounded by a line of weakness. The transparent part of the sheet can then be torn from the opaque area after the latter has been stuck to the headlamp. In a third embodiment the entire sheet is stuck to the headlamp, the non-opaque region being transparent and preferably tinted amber. The sheet may be made of plasticized polyvinylchloride and the opaque area may be backed with silver to protect the sheet from heat.

Abstract: 830,211. Electric measuring devices. MINISTER OF POWER. June 28, 1956 [March 31, 1955], No. 9389/55. Class 40 (1). In apparatus for measuring the velocity of flow of a fluid of determined density, an elastic diaphragm, on which is mounted a number of resistor-type strain gauges, is disposed normal to the fluid flow, the strain thereby imparted to the diaphragm being measured to obtain an indication of flow velocity. A conical section may be attached to the apparatus to increase the flow velocity at the diaphragm, which may be of metal or of other resilient material and which may be protected from the action of the fluid by a heat-proof and moisture-proof covering, as may the strain gauges. The diaphragm may be rectangular, one side or two opposite sides being clamped to a fixed mounting, or trapesoidal, one of the parallel sides being clamped, or of any conveient shape (e.g. square or circular) and peripherally clamped. Fig. 7 shows a paddle-shaped diaphragm comprising a circular portion 1b which is presented to the fluid flow, and a stem 1a, on one or each of whose faces is mounted a strain gauge 3. Fig. 8 depicts a measuring head in which one end of a blade-like diaphragm 1 is clamped within a casing including a tube 4, from the mouth of which the free end of the diaphragm 1 extends into the stream of fluid A, strain gauges 3 being cemented to both faces of the enclosed part of the diaphragm 1 and connected by cables 5 in a bridge measuring circuit, or in series with a battery, the voltage changes across one resistance being measured. Use of a cathode-ray oscillograph for transient indication, and use of a pen recorder for continuous recording, are mentioned. The apparatus may be used to measure high velocity gas flows in e.g. windtunnels, gas turbine engines, aircraft (for determining air speeds) and explosions of gas and dusts, and may be adapted to measure low air velocities.

Title: Improvements in or relating to shock-absorbing struts for aircraft landing gear
IPC: B64C25/60
Filed: 1937-04-05
Abstract: 482,985. Shook-absorbers. VEREINIGTE DEUTSCHE METALLWERKE AKT.-GES., and FAUDI, F. April 5, 1937, No. 9650. Convention date, April 11, 1936. [Class 108 (iii)] A telescopic strut for aircraft landing-gear comprises a cylinder 1 containing independent pistons 3, 7, the rod 2 of piston 3 being secured at its upper end to the fuselage and the rod 6 of piston 7 carrying at its lower end a landing wheel &c., means being provided to transmit power from one piston to the other so that displacement of one piston causes positive displacement in the opposite direction of the other piston. In the construction shown, when a shock occurs liquid contained inside a tube 9, rigidly secured to the cylinder 1 and projecting through the lower piston 7, is forced through channels 19 in the tube, through an annular space 18 between the cylinder 1 and a lining 4, through apertures 20 in the upper end of the lining, and into a chamber 21 behind the upper piston 3, causing the piston 3 to move downwardly relatively to the cylinder 1. The hollow rod 14 of the piston 3 carries a fork 5 adapted to be pivoted to the aircraft fuselage, and a supporting strut is secured at one end to a sleeve 25 on the cylinder 1 and at its other end is hinged on a pivot beneath the pivot on which the fork 5 is hinged. In order to provide a substantially constant resistance to movement of the piston 3 an oil-restricting aperture 13 therein is gradually closed by a conical pin 17 or a slotted or perforated tube, as the piston descends. Springs 22, 23 in chambers 16, 11 bear the whole or part of the weight of the aircraft during and after landing and restore the pistons 3, 7 to normal position. A spring 24 acts as an additional stop for the piston 3. It is stated that in order to obtain a constant track width of the landing-gear (a) the ratio of the cross-section of the chamber 21 to that of the tube 9 may be equal to the ratio of the length of stroke of the piston 3 to that of the piston 7, or (b) the ratio of the cross-section of the tube 9 to the cross-section of the piston 3 may be equal to the ratio of the forces acting on the two pistons. Alternatively, the proportions may be so selected that a slight widening of the track may result so that the direction of the resultant of the landing force on each side of the longitudinal axis of the aircraft is inclined inwardly instead of being perpendicular to the transverse axis. Each strut may be vertically or obliquely arranged.
