Patent GB-219419-A (GB)
Abstract: 219,419. Rudge-Whitworth, Ltd., and Barrington, T. B. May 3, 1923. Brakes, arrangement and disposition of. - In brakes for the steering wheels of vehicles wherein a universal joint is interposed between the torque transmitting shaft and the cam or other member which actuates the brake elements, the complementary members of the joint are so disposed in the initial position before the brakes are applied that steering after the brakes are applied tends to reduce the braking effect on the wheels. In the form shown in Figs. 1, 2, and 3 the universal joint is constituted by a square member e<3>, on the shaft e, the edges of which are rounded, engaging a square aperture in a cylindrical member d located in recesses in the ends of the brake blocks b, b<1> ,and having lugs d', d<2> with rounded ends which engage parallel faces b<2>, b<3> at the ends of the blocks, and the member d is so located that when the brakes are off one diagonal of the square aperture therein is parallel to or in line with the steering pivot. With this construction, the relative movement between the member d, e<3> when the wheels are steered with the brakes applied is such as to reduce the braking effect on the wheels, and since the inner wheel is steered through the greater angle, the braking effect is reduced more on the inner wheel than on the outer wheel if the brakes are applied from a common pedal through connections not provided with equalizing means, whilst when the brakes on the four wheels are similarly actuated, the braking effect on the front wheels is modified as above, and that on the rear wheel is consequently increased during steering. Figs. 8 and 9 show the invention applied to a brake shoe k pivoted at k<1>, and actuated by rotation of the shafts m, n through levers o, o<1>. In this case the shaft n is formed at its outer end with a square aperture n<1> having its diagonals disposed vertically and horizontally and engaged by a member m' at the extremity of the shaft m of corresponding farm to the member e<3> in the construction shown in Figs. 1, 2 and 3. A similar construction for actuating an external band brake is also described.

Abstract: 184,800. Gradl, J. Aug. 15, 1921, [Convention date]. Manures.-A manure consists of finely-divided or colloidal carbon or carbonized organic material in admixture with one or more oxidizers or catalysts or with both. Other manurial substances may be added, the admixture being such that it will give off the carbonic acid which the plants require for their development. Potassium, ammonium and other nitrates are preferably used as oxidizers. Manganese peroxide and other compounds of manganese, clay and other compounds of aluminium, magnesia and other compounds of magnesium, are the preferred catalysts. The carbon may be obtained in admixture with other manurial substances, as by treating sawdust, peat, sea-weed, " humus-lignite," or sulphite lye with sulphuric anhydride and utilizing the resulting sulphuric acid to break down raw phosphates. Manure made according to the invention may be caused to absorb liquid manures such as potash or waste sulphite lyes. In one example, wood charcoal is moistened and mixed with ammonium sulphate, ammonium nitrate being added to the mixture. In another peat is carbonized by concentrated sulphuric acid, water added, and the product used to break up raw phosphate, manganese dioxide being finally added. In a third peat is carbonized by sulphuric acid, which is then neutralized by the introduction of ammoniacal gas, sodium nitrate being finally added.

Abstract: 1350403 Selective signalling HONEYWELL Inc 19 April 1971 [16 March 1970 13 July 1970] 22468/71 Heading G4H In a character generator, the output from a read-only memory is applied via first registers to the memory to obtain a further output, which is applied to second registers. A 6-bit input word together with 3 successive timing signals is applied to a read-only memory to produce in turn three 7-bit ASCII characters which are loaded into output storage from which they are applied to a typewriter (to print 3 characters) or a CRT display. Three groups of 5 bits each from these ASCII characters can be supplied from the output storage to the read-only memory together with timing signals to obtain words of 7, 6, 7, 6, 7, 6 bits respectively in turn which are stored and used to control 3 alphanumeric segmented indicators (each having 13 segments each energized or not by a respective bit). In a control system for building air conditioning, one of a plurality of remote stations (measuring temperature or pressure) sends a message to a central station containing a normalized measurement value in BCD code, an indication of data type and a 2-bit range indication. The indications of data type and range are used to select from a read-only memory groups of bits indicating off-set (2 bits), scaling factor (3 bits) and decimal point position (2 bits). The normalized measurement value is loaded into a counter and a clock pulse source is started and used to decrement the counter to zero at which the pulse source is stopped. The pulse train thus delivered by the pulse source is also fed through a scaling counter, where the number of pulses is reduced in accordance with the scaling factor, to a further counter preset according to the offset required. The final count in this counter is displayed together with a decimal point at the specified position. Letters (e.g. DEG or PSI) are displayed as well, being derived by the character generator above in response to the indication of data type (as the "6-bit input word" referred to above).
