Title: A passenger vehicle with hydraulically operable step
Inventor: HOWARTH DEREK
IPC: A61G3/06
Filed: 1960-11-02
Abstract: 958,128. Platform elevators on vehicles. AUTOLIFTS & ENGINEERING CO. Ltd. Nov. 1, 1961 [Nov. 2, 1960], No. 37610/60. Heading B8E. A loading-platform 10, Fig. 3, on a vehicle slides on guiding columns 58 whilst being raised to a position 10b by an hydraulic ram 28, Fig. 2, and cables 50, 52. Power for driving an hydraulic pump is drawn from the vehicle battery. An overload valve returns liquid directly to a reservoir if the platform jams and when the platform reaches its upper position. Alternatively, a limit switch may cut out the hydraulic pump motor at the upper position of the platform. In both cases a non-return valve prevents the platform from descending. The laterally disposed hydraulic cylinder 28, Fig. 2, carries pulleys 84, 44 mounted respectively on the cylinder and the piston-rod. Cables 50, 52, attached to the cylinder at 46, 48 pass round the pulley 44 and have their opposite ends attached to the platform 10 after passing over guide-pulleys 86, 84, 80, 82, 72. When the piston-rod is projected the cables are effectively shortened and the platform rises.

In a rotary vacuum-pump of the outwardlysliding radial-vane type, a rotor 2 carries at least two vanes 3, 4 with a space 13 provided therebetween, at least one of the vanes having a radial channel 12 therein that is in communication with said space and periodically connected by an opening 14 in the leading face of the vane to a chamber or working space 6 on the high-pressure side of the pump. The opening 14 is situated relative to the radially-outermost end of the vane so that it is in communication with the chamber 6 while the pressure therein is less than the maximum value e.g. during movement of the vane from a position 16 to a position 15, whereby transference of high-pressure gases trapped in said space to the low-pressure side of the pump is minimized. Alternatively, said space is connected to a port 17 by a duct (not shown) in an end plate for the casing 1 of the pump, said port being situated remotely from a discharge port 9 at a position in which it is separated from a suction port 8 by the vanes 3, 4. The port 9 is controlled by a non-return valve 10 that is sealed by oil in a chamber 11.

Title: Aircraft structural fatigue alleviators
Inventor: PRIESTLEY ERIC
IPC: G05D1/00
Filed: 1964-09-16
Abstract: 1,086,938. Automatic control of aircraft. ELLIOTT BROS. (LONDON) Ltd. Sept.9, 1965 [Sept.16, 1964], No.37867/64. Heading G3R. Acceleration due to flexing of an aircraft structure is detected and caused to operate a control surface in such a manner as to alleviate stress. As described, three vertical accelerometers are arranged one at each wing tip of an aircraft and one between them on the fore and aft axis. In one arrangement, the difference between the signal from each wing tip accelerometer and the central accelerometer, resulting from wing deflection, is applied through a servo-system and electro-hydraulic actuator to position an aileron, called an "alleviator, " near the tip of the appropriate wing in such a manner as to counteract deflection and hence stress. In another arrangement, the difference between the average of the outputs from the two wing tip accelerometers and the central accelerometer is applied to control pitch of the aircraft by appropriate control of the alleviators, and the difference between the outputs of the two wing tip accelerometers is applied to control roll of the aircraft by appropriate control of the same alleviators. The latter control may be omitted if unnecessary. More than one alleviator may be provided on each wing. Response of the system may be modified by resistance-condenser networks.

An alternative method of preparation consists in tetrazotizing 1 mol. of the diamino compound obtained by reaction of 2 mols. of 1-nitro-4-aminobenzene-2-carboxylic acid with 1 mol. of a functional derivative of an appropriate dicarboxylic acid, reduction of the nitro groups in the compound thus formed, coupling with 2 mols. of a 1-naphthyl-(21)-3-methyl-5-pyrazolone mono- or di-sulphonic acid or with 2 mols. of a mixture of such pyrazolones and, if desired, metallizing as before.  Preferred dyestuffs are those in which A and A1 are the same and R is a residue of fumaric, muconic or terephthalic acid.  Specified functional derivatives of dicarboxylic acids are fumaric acid-, chloro- and bromo-fumaric acid- and mesaconic acid-dichlorides, butadiene-, 1,4-dichlorobutadiene-, 2-methylbutadiene- and benzene-1,4-dicarboxylic acid chlorides and 2-methyl-, 2,5-dichloro-, 2-acetylamino- and 2-carbethoxyamino-benzene-1,4-dicarboxylic acid chlorides.
