Title: Anti-skid control systems
Inventor: FINK W
IPC: B60T8/173
Filed: 1972-05-04
Abstract: 1326857 Anti-skid brake control systems ALFRED TEYES GmbH 4 May 1972 [7 May 1971] 20837/72 Heading F2F  In operation of a motor vehicle anti-skid brake control system, a control member 26, 27 is actuable to cause a decrease in pressure at a wheel brake cylinder B in response to a signal from an AND-gate 22 which during a braking cycle is triggered by the combination of a signal resulting from the attainment of a predetermined rotational deceleration of the wheel, and a signal indicative of a predetermined change (decrease) in speed of the wheel detected after the moment when the predetermined deceleration value is reached. As shown, a deceleration sensor 21 delivers its output signal ## directly to AND-gate 22 and also to an integrating member 23 the output signal AC of which represents the change in speed of the vehicle wheel. When the AND-gate 22 is triggered by the combination of both signals, two holding members, e.g. bistable multivibrators 24, 25 are reversed to act on the control member. The control member comprises a normaly open input valve 26 between a master cylinder M and the brake cylinder B and a normally closed output valve 27 inserted in a hydraulic connection from the brake cylinder B to a reservoir R, and the multivibrators act to close the valve 26 and open the valve 27 to relief braking pressure and allow deceleration of the wheel to decrease. The signal from sensor 21 is also fed to a differentiating member 28 and a negating member 29 which emits a signal if zero acceleration or decleration is measured. The differentiating member 28 is followed by detectors 31, 32 which determine the upward or downward tendency of the deceleration curve (Fig. 2). The outputs of these detectors 31, 32 are applied together with the output of the negating member 29 to AND-gates 33, 34 respectively which are triggered to act on the multistable vibrators 24, 25 thence an upward tendency of the decleration curve together with a signal from the negating member 29 (point 2 in Fig. 2) causes the valve 27 to close, the pressure in the brake circuit being kept constant; a downward tendency of the deceleration curve plus a signal from negating member (point 3 in Fig. 2) causes the valve 27 to open so that brake pressure can be built up again and a new cycle starts.

Title: Improvements in couplings for railway vehicles
IPC: B61G5/08
Filed: 1920-07-12
Abstract: 149,250. Krum, G. Jan. 13, 1919, [Con vention date]. Couplings, non-automatic.-In a non-automatic coupling for railway carriages, the hook is free to move in a horizontal plane, and is enclosed in a cage through which a transverse shaft, accessible from the side of the vehicle, actuates through gearing, the link of the hook. The coupling rod a has a hook t on one side of the head and an inclined surface r on the other. Two superposed holes, the upper one 3 being shown, connect the steam and air services respectively through the medium of the slide n when the coupling is connected up. The link o has one end closed to form a stem and is connected together with the bell crank lever u, to the end of the slide n. To connect the opposing halves of either handwheel k, this forward movement slides the link o up the incline r against the pressure of the leaf spring s and opens it in a horizontal plane. The forward movement of the slide tilts the bell crank lever u and retains the hook w in the open position and at the same time shuts off the steam and air ports in the rod. On reversing the handwheel k the slide is drawn back, the link o drops into the opposing hook t, the hook w engages the eye of the bracket z on the opposing half of the casing b and the steam and air passages put in open circuit respectively through the medium of the ports in the slide valve.
Patent GB-221513-A (GB)
Title: Improvements in the production of nitric acid from ammonia
IPC: C01B21/26
Filed: 1924-09-06
Abstract: 221,513. Synthetic Ammonia & Nitrates, Ltd., (Assignees of Greathouse, L. H.). Sept. 6, 1923, [Convention date]. Nitric acid of from 60-70 per cent strength is obtained directly from nitrogen oxides, produced catalytically at elevated pressure from a mixture of ammonia and air or oxygen, by regulated cooling in stages while still under pressure. In the plant shown in the Figure ammonia and air entering at A are compressed in compressors B and led to a catalytic chamber D. The resulting nitrogen oxides are cooled in four stages whereby a solution of nitric acid is obtained by condensation. After leaving an air cooler F, the nitrogen oxides are cooled by a water cooler H and then by a cooler J in which the temperature is reduced to 0 C. The condensed nitric acid at this point is led away from the gaseous stream and is cooled to about -10 C. in the cooler O which is so arranged that it discharges the cooled acid into a cooler Q receiving the uncondensed nitrogen oxides leaving the cooler J. The temperature of the cooler Q is maintained at about -10 C. by means of brine, the concentrated nitric acid leaving by the pipe U. Uncondensed gases leaving the cooler Q pass in counter current to the nitric acid in cooler O and finally leave the plant at T. Water and oxygen may be introduced at any point in the plant as desired. The energy of compression of the gases may be recovered by utilizing the expansion of the gases leaving the exit pipe T, for refrigeration.

Title: Apparatus for determining and controlling variations in the gas exchange of living organisms
IPC: G01N33/497
Filed: 1969-04-24
Abstract: 1,261,773. Treating plants. SIEMENS A.G. 24 April, 1969 [30 April, 1968], No. 21103/69. Heading A1E. [Also in Division G3] The evolution of water, and absorbtion or evolution of carbon dioxide in an experimental chamber 1, is measured using servo mill detection methods. Air is pumped by pump 3 through humidifier 6, humidity controller 4, and humidity detector 18 into experimental chamber 1. The gas from the experimental chamber passes through humidity detector 17. Gas from the experimental chamber passes through pump 12, flow meter 13, vapour trap 14 and back into the chamber and control box 16 adjusts the temperature of vapour trap 14 so that the humidity of gas entering and leaving the experimental chamber is the same. Moisture evolved by the plants is determined from the moisture collected in vapour trap 14. The CO 2  level in the chamber is controlled by gas container 24 feeding through control valve 25 and flow meter 26, and gas being pumped from the chamber by pump 29 through flow meter 30, CO 2  fixer 31 and valve 33. Control valves 26 and 29 are operated by control boxes 27 and 32 so that the CO 2  content of gas entering the chamber 1, is the same as that leaving the chamber 1, as detected by infra-red absorbtion detector 9. The gas entering infra-red absorbtion detector 9, taken from before and after passage through chamber 1 is passed through vapour trap 8 to ensure that both gas streams have the same reduced water content. The CO 2  removed from or supplied to the chamber is thus measured. In a modification the loop 29, 28, 30, 31, 28, 33 can go from chamber 1, direct to vapour trap 8. The experimental chamber has its temperature controlled by means of temperature controller 10 and a Peltier heat pump. The vapour traps and humidity controllers operate by using Peltier heat pumps. The moisture detectors are of the LiCl type. The CO 2  fixer is either caustic soda, or caustic potash.

Abstract: 432,768. Screw propellers. LAMMEREN, W. P. VAN, 45, Veurscheweg, Voorschoten, Holland. July 21, 1934, No. 21378. [Class 114] In a variable-pitch screw propeller of the type in which the pitch of the blades is varied by means of the centrifugal force exerted by weights rotating with the boss of the propeller in connection with adjustable compensating springs, the adjusting means on the blade and a member movable by the rotating weights are connected by a balance beam which has a variable fulcrum. Each blade a is mounted in the boss by ball bearings which take the thrust due to centrifugal forces ; each blade has attached thereto a crank g. A weight h is pivoted at i to the boss, and has pivotally connected thereto a rod l which is connected by a beam m with a rod n connected to the crank g and guided by rollers r ; an adjustable spring o is interposed between the free end of the weight h and the crank g. When stationary the blade is in maximum pitch position being held by the spring o against a stop p. The beam m rests on the curved surface of the hub so that as the weight moves outwardly to decrease the pitch the fulcrum moves along the surface, thus maintaining the desired relation between the pitch and the rate of revolution. In one instance, the curved surface is shaped such that the third power of the pitch varies inversely proportional to the square of the number of revolutions per unit of time.
