Patent GB-826472-A (GB)
Abstract: 826,472. Calculating apparatus. SPENCE, T. Feb. 15, 1956, No. 4669/56. Class 106 (1). [Also in Group XV] In a calculating apparatus comprising a measuring rule A with an additional scale H of equally-spaced numbers in consecutive rising order for co-operation with a similar scale K on a slide E carried by the rule, the scale on the slide is marked at a longitudinal edge of a window F in the latter which exposes the rule scale H, and a defined length of the window edge equal to and immediately preceding that occupied by the numeral " 1 " of the slide scale serves as a primary index for performing additions and subtractions. As shown, a further scale L, expressing shillings and pence or feet and inches, is arranged side by side with scale H and is similarly spaced, and the rule has conventional markings B, C, D, and on the reverse side continuations H<SP>1</SP>, L<SP>1</SP> of scales H, L, and a transverse scale M heading columns N of rising numbers 1-12 spaced in accordance with the corresponding number in scale M. Slide E has a front window F, and on the reverse side a window G, a scale K<SP>1</SP> similar to scale K, and transverse scales O, O<SP>1</SP> similar to scale M. To add, say 9 and 6, the upper edge of window F is positioned just below number 9 on scale H, and the total read off scale H opposite the other number, 6, on scale K. For subtraction the two numbers are arranged opposite each other on scales H and K and the answer read off scale H just above the upper edge of window F. Conversions are made by comparisons of scales H and L. To multiply or divide, the top or bottom edge of slide E is used as an index. Thus as shown, to multiply 6 and 4 the lower edge of slide E is positioned just above 6 in the " 4 " column N and the answer read off on scale H below the lower edge of the slide. To divide, the dividend on scale H is set below slide E, and the quotient read in the column N opposite the divisor on scale O. Scale O and columns N show the factors of the number set on scale H. A remainder, if any is found by counting the blank squares from the edge of slide E back to the last figure in the appropriate column N.

Title: Crane hoist protection system
Inventor: GRIDER LYLE DELBERT
IPC: B66D1/52
Filed: 1983-01-05
Abstract: The reversible drive for the whip hoist of a crane comprises a pair of hydraulic motors 11,12 coupled to the whip hoist winch and a reversible hydraulic pump 13 for supplying hydraulic fluid to the motors via main raise and lower fluid lines 14,15, the arrangement being such as to form a closed loop hydraulic circuit. A normally set winch brake comprising an automatic brake and clutch arrangement 22 is controlled by an hydraulic brake cylinder 23. The brake cylinder 23 is spring biassed to the position in which the brake is applied and it is actuated to release the brake by fluid pressure in the lower fluid line 15, thereby to allow the winch drum to pay-out cable. A protection system for the whip hoist comprises a bypass closed loop circuit connected between the raise and lower fluid lines 14,15 and including relief and shut-off valves 24,25. These valves are arranged to limit the fluid pressure in the raise line and, hence, the winch cable tension. In this connection, a load cell positioned on the crane boom is responsive to an overload tension in the winch cable to produce an hydraulic signal which is transmitted, via a line 61, to actuate the protection system. Over-ride and control valves 41 and 50 are responsive to this hydraulic signal for, respectively, overriding the normal operation of the winch brake and opening the shut-off valves 25, thereby to release the winch brake and cause the bypass circuit to function. <IMAGE>

Title: Process for the heat treatment of fine-grained material
Inventor: MAURY HANS-DIETMAR
IPC: F27B7/20
Filed: 1986-06-03
Abstract: A process for heat treating fine-grained material, in which the material is first pre-heated in a pre-heater (2) and is then pre-calcined in a furnace exhaust gas duct (5) prior to entry into the furnace (1). Hot gases for the pre-calcining process are provided by the combustion of a supplementary fuel, for which air is supplied to the exhaust duct (5) from a condensor (6) in two currents through ducts (7a, 7b). Evolution of noxious nitric oxides during pre-calcining is avoided by feeding the supplementary fuel exclusively to the lower air duct (7a), such that sub-stoichiometric combustion occurs prior to the entry into the exhaust duct (5) of the second air current which completes the combustion of the supplementary fuel before entry of the material to be pre-calcined into the upper part of the furnace exhaust gas duct. The process further prevents harmful volatile substances, present in the furnace exhaust gases, from entering the pre-heater, by feeding the pre-calcined material into the lower part of the furnace exhaust gas duct, below the entry point of the first current of air.
