Title: Improvements in or connected with Eyepiece Prism Combinations for use in Optical Instruments of the Self-contained Base Type Adapted to be Used for Rangefinding.
IPC: G01C3/02
Filed: 1917-06-14
Abstract: 127,885. Barr & Stroud, and French, J. W. June 14. 1917. Range-finders; micrometer systems.-Relates to eyepiece prism combinations for use in short home-base range-finders. The thickness of the parts is small in comparison with the transverse dimensions, and the construction is such that, of rays of a main system proceeding in the normal direction, some pass directly through the combination, while others are obstructed by means in the prism combination, which means also serve to reflect rays of one or more subsidiary systems so that they emerge in the normal direction with the emergent rays of the main system. The principal parts are made of parallel-plate form, and the thickness may correspond to a definite angular value of the field of view. The prism combinations described are suitable for instruments having an eyepiece between end reflectors and so constructed that the rays of the main and subsidiary systems ultimately enter the prism combination from one and the same direction; they are also suitable for use in periscopic rangefinders. In the construction Shown in Fig. 1, the principal part comprises two'main parts 1, 2 having oblique meeting faces, which are joined together, as by cementing. A layer of silver is provided on the oblique faces to obstruct part of the main rays and to reflect a subsidiary system of rays directed on to the layer 5 by. a reflecting- face 8 formed on the part 2. The field of view obtained is divided into two parts A, B, as shown in Fig. 3. Plates 9, 10 may be cemented on, as shown in Fig. 1. Either or both of the plates 9, 10 may be formed with a lens ,surface, and the reflector for the subsidiary rays may be a separate prism secured to the plate 9. In the construction shown in Fig. 7, two portions 5<A>, 5<B> of the oblique face are silvered and are intended for use with two separate reflectors (an intermediate and a bottom one) of a periscopic range-finder, the rays of the main field coming from the top reflector of the periscope. Another combination, shown in Fig. 9, has the principal portion in three parts 1, 2, 2A with oblique meeting faces having two reflector bands 5<A>, 5<B>. In Fig. 10 are shown reflector bands 5<A>, 5<B> meeting along a line 4 and capable of use for short and long base rangetinders in the same manner as the forms shown in Figs. 7 and 9. The form shown in Fig: 10 is also applicable for use in an instrument having an upper and a lower reflector at the ends of its base, associated with a periscope comprising a top reflector not used for range-finding. Fig. 13 shows a combination having three reflecting-bands 5A, 5<B>, 5<c> intended for use with a periscopic instrument comprising three range-finders.

Title: Aircraft capable of helicopter and propeller modes of operation
IPC: B64C27/50
Filed: 1969-02-18
Abstract: 1,260,218. Convertiplanes. UNITED AIRCRAFT CORP. 18 Feb., 1969 [20 March, 1968], No. 8686/69. Heading B7W.  A convertiplane 10 has at the tip of each wing 14, 16 a rotor pod 34, 36 of which the forward part 52 is tiltable to convert the aircraft from helicopter mode, Fig. 1, to propeller mode, Fig. 2 (not shown), and which contains means to fold and unfold the blades 40 about their flapping axes 100 to convert the aircraft from the propeller mode into a fixed-wing jet-propelled aricraft, Fig. 3, and a nose cone 56 which is moved forward during unfolding of the blades 40 so as not to interfere with the rotor and back during folding to form a smooth aerodynamic surface with pod 34. The forward part of the pod is tilted by an actuator 60. The blades are controlled in cyclic and collective pitch by a swash plate assembly 114, Fig. 4A, which is positioned by means of three main servos such as 124. Signals from the pilot cyclic and collective pitch control sticks 152 are transmitted to the main servos for example 124 through mixing linkage 154, Fig. 4B, auxiliary servos 156 and a bell crank link system 158 to comprising a stationary portion 174 and a movable portion 190 on the forward part of the pod joined by twist links 176a, 176b, 176c of the kind shown in Fig. 7 (not shown), closely clustered around the pod tilt axis 58 so that the tilting of the pod does not introduce inadvertant pitch change to the blades. Similarly the connection between the swash plate assembly and each blade comprises a bell crank link system 130 to 150, Figs. 5, 4A, which includes a link 138 which extends along and is translatable along the blade flapping and folding axis 100 so that flapping does not introduce any inadvertant pitch change. When the blades are to be folded the normal rotor pitch control system is inactivated with the blades in the full feather position and linear actuators (250, 251, 252), Fig. 9 (not shown), which are between the main 124 and auxiliary 156 servos are controlled to provide a linear output to the main servos 124 during the first eighty degrees of folding. At this point microswitch (270) is actuated which causes the blades to have their pitch changed by reversible motors (262, 264, 266) so that they nest with the pod in an exposed position. During unfolding a microswitch 260, Fig. 4A, is activated by the initial blade movement and brings the blades to the full feather position for the last eighty degrees of unfolding.

Title: Improvements relating to the launching of flares and flash devices from aircraft
IPC: B64D1/02
Filed: 1944-05-08
Abstract: 590,364. Dropping flares &c. from aircraft. ROE & CO., Ltd., A. V., and BEARDSHALL. G. May 8, 1944, No. 8710. [Class 9 (ii)] Means for launching flares, flash-devices or the like from aircraft comprise a wind baffle in conjunction with shoots down which the flares &c. travel, the baffle being projected before the delivery of a flare or flash device to a position in which it shields the flare &c. from wind pressure whilst the flare &c. moves completely clear of the shoot so that it is not liable to be locked in the shoot by wind pressure. The baffle a is mounted by rollers b running in guide channels c, a nut d being connected to the baffle by pins e which can be withdrawn by a cross-bar f to release the baffle and allow it to fall in case of emergency. Within the nut d is threaded a long screw g, rotatable by an electromotor h. Limit switches, one of which is shown at n, are operated by brackets j, k on the baffle in its extreme positions, to put the motor out of circuit or to reverse it as required. , A container q for flares or the like is supported in a .shoot o by a door p and a flash device container z is held in a shoot 2 by a door 3, the doors being locked in the closed position by catches (not shown), released when solenoids are energized, or by hand. In use, on the opening of the bomb doors, which are electrically interlocked with the baffle, the motor h is automatically switched on, and projects the baffle. The latter, when in the operative position, serves through the switch n to prepare the circuits of the solenoids bv which the doors p, 3 are controlled. The pilot puts into operation, when required, the solenoid that effects the release of the flare, while the door releasing the flash device is opened automatically when the bombs are released. Both the flare and the flash device are ignited automatically after being released from their shoots, and the ignition control for the flash device also effects the operation of a switch which brings a camera into action. After the devices have been discharged, the doors of the shoots are closed by pressure, on a pedal lever which is linked to the door-hinge pin. Flares for navigational aid may be discharged independently of the opening of the bomb doors, the motor h for the baffle being in that case operated by a special switch.

Abstract: 311,874. Stringer, H. L. March 22, 1928. Actuating; boards, colour screens, and shutters, reciprocating; elements moving always in one plane, rotating and oscillating; reel and endless web apparatus.-A sign of the type in which the legend is seen in an inclined mirror is provided with a shutter which is reciprocated by an inertia motor so as to display two words alternately. A horizontally arranged glass stencil 5 is provided with a tab 7 whereby it can be withdrawn for substitution. Over the stencil a shutter 8 provided with a row of apertures 9 is reciprocated on wires 55, either longitudinally or transversely, by a pin 35 engaging a slotted lug 37. The pin 35 is mounted on a disc 26 which is flicked through 180‹ at a time by a spring connecting it to a pulley 17 which is rotated intermittently and unidirectionally by the oscillation of a mass 10 energized by the vibration of a vehicle on which the sign is carried. The mass 10 is counterbalanced by a spring 13 and is spring-buffered. A cord 16 connected to the mass 10 passes round the pulley 17 and is tensioned by a spring 18, a branch cord 23 being adjustably attached to the cord 16 to vary the movement of the pulley. A second spring- tensioned cord 21 passing round the pulley acts as a reverse detent.. The spring reservoir between the pulley 17 and the disc 26 is controlled by a tooth 32 on the disc which is held by blade spring 33 till a projection 34 on the pulley 17 comes round and by pressing away the spring 33 releases the tooth and the disc 26. Fig. 6 shows a modification in which the sign is mounted on a framework 38, 39 which is pivoted at 40 and provided at one end with a spring 42 and at the other with a weight 43. The driving cord 16 is fastened to the base 41 and passes over a guide roller 47 to the driving pulley located in a box 45 at the end of the casing. The disc 26 is connected to the shutter by a pivoted rod. Rubber buffers 44 cushion the oscillating casing. Fig. 9 shows another form in which an oscillating mass is located outside a fixed sign casing 1. The mass comprises a beam 49 pivoted at 50 and biassed by a spring 51, cushioning springs 54 being provided at its outer end. In all the modifications the stencil may move and the shutter be fixed, or the stencil may be in the form of an endless band driven from the pulley 17, or be arranged round a disc rotated by the inertia motor. In the latter case the disc is disposed in a square box having four separate, mirrors whereby the changing legend can be seen on four sides. Alternatively the stencil or the shutter may be pivoted and rotated through an angle periodically. The shutter may carry coloured screens, and may be moved step-by-step across the stencil. The mass 10 may be detachable for substitution. The spring reservoir may comprise on the driving pulley a crank or eccentric connection to a blade spring which bends into a bow against a catch till it snaps past. Ratchet and pawl mechanism may be substituted for the cord and pulley driving means. Specifications 193,997 and 325,635 are referred to.
