Filed: 1955-06-02
Abstract: 788,749. Treating wood. AUCLAIR, G. June 2, 1955, No. 15806/55. Class 140. [Also in Group XXIII] A method of manufacturing wood plies 10 comprises impregnating the plies with a thermosetting resin, e.g. by vacuum and pressure impregnation or by prolonged immersion, and rolling the plies, e.g. between three pairs of rollers 11 ... 16 at a temperature below the setting temperature of the resin. The spacing between each pair of rollers decreases in the direction of travel of the ply 10, e.g. being 1.6, 1.3, 1.0 mm. respectively. The pressure is 250 kg. per cm. length of roller.

[Classes 78 (i), 78 (iii) and 78 (iv)] [Also in Group XXXIII] A mobile device for loading and unloading aircraft comprises a selfpropelled carriage on which are mounted a ramp and a vertically movable platform. The upper end of the ramp is pivotally connected to the platform and the lower end is free to slide in a horizontal plane. The platform 24 is supported by two pairs of members 27, 28 which are connected by a pivot 29. Each member 27 is pivoted to the chassis 4 at 30 and is provided with a pin 31 which engages a slot 32 formed in a member attached to the platform. The member 27 is locked to the platform in any position by inserting a pin 39 through a hole near its upper end into any one of a series of holes 38 formed below the slot 32. Similar means is provided for securing the lower end of each member 28, but in this case the pin engaging the slot is secured to a nut 36 which is traversed.by the rotation of a screw 37 driven by the engine. The platform is connected by a pivot 23 to a ramp 20, the lower end of which rests on the side plates 13 of the chassis and takes beneath the horizontal surface 12a of a plate 12b which extends across the full width of the chassis. A frame 17 of triangular crosssection is pivoted at 16 to the plate 12b and either can rest on the ground with its inclined surface 18 forming a continuation of the surface 12b, or be turned up so that its horizontal surface forms a continuation of the surface 12a. Loads are raised and lowered by a cable 43, which is passed over pulleys 46, 44 to a winch 42, and may be withdrawn from the aircraft by passing the cable over a pulley 45. When heavy loads are being handled, jacks 47 on the undercarriage may be brought into contact with the ground and jury struts may be placed between the platform and chassis. In order that the device may be used with an aircraft, the door in which is inclined relatively to the ground, the platform is provided with a pivoted triangular extension 49a, Fig. 2, which is retained in position by catches 51 slidably mounted in its edge and adapted to grip the sides of the door. The upper surface of the ramp may be provided with an endless belt conveyer, a number of rollers, slotted tracks for motor vehicles, rail tracks for trolleys or rail vehicles, and one or more gangways for passengers. Similar tracks &c. are provided on the platforms 24, 12a. The chassis can be made of detachable units 4a, 4b, 4r which are provided with wheels 52 for mobility. The platform 24 may be actuated by a system of mechanical, electrical or hydraulic jacks.

As shown in Fig. 1, the shoes 14, 16 are pivotally connected by an adjusting device 18, slotted at its ends to engage the shoes and held in engagement by a spring 20. The free ends of the shoes are normally both held in contact with a flat-sided fixed anchoring post 24 by a spring 28. A second spring 30 may be connected to the post 24 and to the shoe 16 to prevent this shoe from leaving the anchor unless the drum is turning backwards (clockwise). The piston-rods 34 of a hydraulic cylinder 32 fixed to the back plate have yokes that embrace the webs of the shoes and engage pins 38 thereon. Alternative mechanical means for applying the brake comprises a lever 40 pivoting on one of the pins 38 and connected by a thrust rod 42 to the other shoe. The lever is operated by a cable 48, bell crank 52, and a Bowden cable 54 passing through the back-plate.

Title: Apparatus for receiving, selecting and amplifying electrical signals arriving as impulses of different polarity
IPC: H04L5/04
Filed: 1932-06-08
Abstract: 403,414. Code telegraphy ; valve circuits. OSTI, A., 17A, Via M. Mercati, Rome. June 8, 1932, No. 16208. Convention date, June 8, 1931. [Classes 40 (iii) and 40 (v).] A push-pull pair of valves is so selected and biased that weak signals are not passed on, and one valve is affected by positive signals only while the other is affected by negative signals only. The valve system feeds a system of electromagnetic relays which correct for zerowander and pass on positive and negative impulses segregated into separate channels at a standard strength. Thermionic amplifier. Valves 1, 2 segregate the positive from the negative impulses ; if the polarity of an impulse is such that terminal E1 becomes positive with respect to terminal E2, valve 1 passes grid current and most of the potential-drop is applied to the valve 2, serving to produce a decrease in the normally flowing current. The valves 3, 4 of the second pair are so selected (Fig. 2, not shown) and biased that they do not respond to weak interfering signals but rapidly produce a saturation current as the signals surpass a certain strength. In the device described in the following paragraph thermionic valves may be substituted for electromagnetic relays. System of relays for correcting zero-wander. Positive or dot impulses from terminals Rp, Fig. 3, are applied to terminals Up, Fig. 4, and negative or dash impulses from terminals Rn are applied to terminals Un. Dot impulses pass from terminals Up to relay R1, moving its armature from d 1 to f1 and thus controlling the dot-sending-on relay R5, whose armature shortcircuits the resistance Pr1 and so sends on a dot signal through valve V5. At the same time relay R3, controlled by relay R0 which also is energized by the dot signal, connects the dash-sending-on relay R6 in such a way as to ensure that this latter. shall not be operated. When a dash signal is received the parts Un, R0, R2, R6, Pr2, R4, R5, V6 operate in the manner just described with reference to the parts Up, R0, R1, R5, Pr1 R6, V5. The relay RO is operated by dot and by dash signals alike, moving its armature to the right. When a zero signal is received it moves its armature to the left and so (1) puts the resistances rb1, rb2 in shunt to the bias windings B1, B2. It thus increases the sensitivity of relays R1, R2, so that they may be operable even by signals which have been weakened by zero-wander. Relay R0 also (2) on receipt of a zero signal causes relays R3, R4, to prevent ambiguous control by breaking any interconnection between R1 and R6 or R2 and R5, so that the armatures of R5 and R6 are both moved to the right on account of contact being made at d1, d2, and zero signals are sent on.
