Title: Mobile gantry crane
Inventor: MUNNES ODD PEDER
IPC: B66C19/00
Filed: 1966-02-22
Abstract: 1,134,328. Steering vehicles. NYDQVIST & HOLM A.B. 22 Feb., 1966 [22 Feb., 1965], No. 7784/66. Heading B7H. [Also in Division B8] In a mobile gantry crane (see Division B8) comprising a crab ortrolley (5) (Fig. 1, not shown) on a cross-member (1) supported at its ends by side members (2) and (3) which are each mounted on a pair of wheels, each of the wheels (A), (B), (C), (D) is turnable about a vertical axis between two positions at right angles to each other under the control of a turning member (18), whereby the crane may travel in a direction longitudinally or transversely of itself and is steerable by steering means co-operable with the turning members to turn the axis of each wheel in a horizontal plane about a vertical axis to steer the wheels whether the crane is moving longitudinally or transversely. On rotation of a steering wheel 21 all the wheels are steered together, pairs of wheels describing common arcs. The steering wheel 21 has a telemotor connection (Fig. 12, not shown) with an hydraulic cylinder 40, on cross-member (1), the piston 42 of which is connected by cables, slidable in sheaths 47, 48, with gear-racks 49, 77 engaging gear-wheels in identical control members 22, 23. Control member 22 comprises a shaft 56 (Fig. 13) to which are secured two cam discs 57, 58, each having two grooves engageable respectively by projections 67, 68 and 69, 70 of two claw clutches 61, 62 mounted on rods 59, 60. The shaft 56 is vertically adjustable by a piston 72, connected hydraulically to the turning member 18, between positions in which the upper grooves and the lower grooves respectively of the discs are engaged by the claw clutches. The grooves are of the correct shape (Figs. 6, 10, 15, 16, not shown) to turn the wheels A, B, C, D as required for longitudinal or transverse movement of the crane. On rotation of the steering wheel 21 the rods 59, 60 and corresponding rods 79, 80 on the other side of the vehicle are moved axially each operating a spool valve (Fig. 17) in a respective valve unit 101, 102, 103 or 104 which controls the flow of hydraulic fluid to. a steering element at the corresponding wheel. Each steering element comprises a cylinder 81 and a piston 83 with rack teeth 85 in mesh with gear teeth 87 on a vertical shaft on which a wheel is mounted. Each vertical shaft also has gear teeth 96 meshing with a rack on a feed-back rod 97 which is connected to one end of a lever 108 (Fig. 17) to which are pivoted at the middle and at the other end the end 107 of the valve spool and the rod 59 respectively. The feed-back rod includes an hydraulic length adjustor comprising a cylinder and piston attached respectively to the two parts of the rod 97 and connected hydraulically to the turning member 18 for adjustment when the member is altered between its longitudinal and transverse travel positions.

Title: Improvements in and relating to apparatus for the production and transmission of electrical impulses
IPC: G08C19/16
Filed: 1934-03-12
Abstract: 431,730. Electric signalling systems. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. March 12, 1934, Nos. 7795 and 7796. Convention dates, March 11, 1933 and Aug. 19, 1933. [Class 40 (i)] [See also Group XL] Impulses or current variations for telemetering &c. are produced by varying the circuits of a valve oscillator, the variations in the anode current when oscillation commences and ceases being utilized for controlling a distant step-by step or other indicator. The rotation of the meter spindle varies the reaction between the anode and grid circuits of the valve. In the arrangement shown a plate 8 on the meter spindle 9 increases the capacity between the plates 4, 6 thus causing the valve to oscillate at each rotation of the meter. The consequent reductions in the anode current thus produce impulses in the line circuit and operate a distant indicator. In a modification, the reaction between the anode and grid circuits is varied by a toothed metal disc on the meter spindle, Figs. 2 to 6, (not shown). In a further modification in which positive and negative impulses are sent to line alternately, two oscillators are connected in the impulse circuit in opposite senses, and a polarized relay at the receiver in each position of its armature charges one condenser and discharges another through an ammeter. The notches in the toothed disc are so arranged that the valves oscillate alternately, two or more reaction coils in series being used for each valve, if necessary. The toothed discs may serve as brake discs for the meters. In systems in which the impulses are separated by intervals of time proportional to the value to be measured, reaction coils in the plate and grid circuits are moved at a constant speed so as to pass over a vane fixed at the zero point and over a second vane carried by the pointer of the instrument. As the coils pass over each vane, oscillation ceases, impulses being thus produced in the anode circuit at an interval determined by the position of the pointer. In a further modification, (Fig. 7, not shown) the average value of the anode current is determined by the torque exerted by the meter on a spindle carrying a moving coil through which the anode current passes. The impulses or current variations may be used to control a wireless transmitter either by means of a contact-making relay or by utilizing the potential across an impedance in the anode circuit to modulate a carrier.

Title: New azo compounds
Inventor: ATKINSON JOHN REGINALD
IPC: C09B62/026
Filed: 1962-03-01
Abstract: The invention comprises monoazo compounds of the formula <FORM:1029212/C4-C5/1> wherein X stands for any aromatic radical which is free from azo and sulphonic acid groups R1 represents a labile atom or group which is free from sulphonic acid groups, A represents a 1:3:5-triazine or pyrimidine radical and R2 represents a labile atom or group which is free from sulphonic acid groups and which may be the same as or different from that represented by R1 or for a group containing an oxygen, sulphur or nitrogen atom through which it is connected to the triazine or pyrimidine nucleus which is free from sulphonic acid groups and which is not a labile group and the metal complexes of such of these compounds as contain a metallizable group in X in ortho position to the azo group. By a labile atom or group there is meant an atom or group which is free from sulphonic acid groups and which is bound by a covalent bond to a carbon atom of the triazine or pyrimidine nucleus but which readily dissociates under the influence of heat or alkalis, especially in the presence of moisture to form an ion or an uncharged molecule and leave a residue capable of reacting with the cellulose molecule.  X may be a benzene, naphthalene or benzthiazole series radical.  Such dyes are prepared by reacting appropriate diazonium compounds and coupling components or by reacting a monoazo dye corresponding to the above formula in which at least one of R1 and R2 represents a halogen atom with a tertiary amine or a compound of the formula RH or an alkali metal salt of such a compound where R represents a labile group or a group connected to the hydrogen atom by an O, S or N which is not a labile group.  Metal complexes may be prepared by appropriate metallization procedures.  In examples: A red dye for polyamides is obtained by diazotizing p-aminoacetanilide and coupling with 2-chloro-4 - di - (b  - hydroxyethyl)amino - 6 - (41 -hydroxynaphth - 11 - yl) - 1:3:5 - triazine (1) and a grey dye for wool by chroming the dye 4-nitro-2-aminophenol with [41-chloro-61-di-(b -hydroxyethyl)aminopyrimid - 2 - yl] - 4 - naphthol. Additional examples are furnished.ALSO:4,6 - Dichloro - 2 - (41 - hydroxynaphth - 11 - yl) pyrimidine is obtained by reacting 2: 4: 6-trichloropyrimidine with 1-naphthol in the presence of aluminium chloride and benzene.
