Abstract: 721,279. Friction clutches. SIEMAG VERTRIEBSGES. Oct. 18, 1951 [Nov. 6, 1950]. No. 24300/51. Class 80 (2). A clutch with an overload disengagement device, comprising a plurality of laminae in which the relative slip of the driving and driven clutch halves influences, through a driven element connected with one of the halves, a disengaging element arrahged in the other half in such a way that the said disengaging element disengages the clutch, is characterized by the driven element being formed as one, 7, of the laminae and in the form of a toothed wheel (or screw threaded wheel) cooperating with the disengaging element. The disengaging element consists of a segmental toothed &c. wheel 5 secured to a spindle 2 in the driving clutch part 1, so that, by its rotation on relative movement between the driving and driven clutch halves, a valve 3 is operated to relieve the hydraulic pressure upon a clutch engaging piston 9. Means are provided for preventing the continued rotation of the wheel 5 after the clutch has disengaged, the clutch being re-engaged by turning a handwheel 4. In a modification, Fig. 3 (not shown), the laminae 7 has threaded instead of toothed engagement with the wheel 5. The device may also be applied to electromagnetic clutches.

Title: Improvements in and relating to aircraft landing lamps
IPC: B64D47/04
Filed: 1947-09-04
Abstract: 627,946. Aircraft landing lamps. HARLEY, M. C. Sept. 4, 1947, No. 24397. [Class 75(iii)] A retractable aircraft landing lamp a is actuated by an electric-motor-driven telescoping mechanism i with end limit switches, this mechanism being anchored at its fixed end to a bracket k held resiliently to a fixed base j. The lamp in its retracted position is thus resiliently held to its seating f in its housing e so preventing icing up. The bracket k has a pair of bolts m passing through holes in a base formed by the end flange of a bracket j which supports the housing e and carries the pivot d about which the lamp is turned. Compression springs n secured by adjustable nuts o surround the bolts m and abut against the end flange to draw the anchoring bracket k thereagainst. In operation, when the lamp a is retracted to abut against the seating surface f of the mounting e, a pre-adjusted limit switch allows continued operation of the telescoping mechanism i until the anchoring bracket k is pulled slightly away from the end flange against the action of the springs n. The pivoting arm b by which the lamp is carried is radiussed about its hinging centre to conform with the contour on the flanges c c of the main bracket and provide a fluidtight seal therewith. The mounting e may have a peripheral flange seated between a pair of ball races to allow rotation of the housing for use of the lamp as a searchlight.

Title: Cascade heat exchanger or reactor
IPC: B01D47/02
Filed: 1964-06-17
Abstract: 1,112,372. Contact apparatus. N. J. HASSETT. 17 June, 1965 [17 June, 1964; 15 July, 1964; 18 July, 1964], Nos. 25015/64, 29057/64 and 29626/64. Heading B1F. [Also in Division F4] A contact heat exchanger for heating or cooling falling granular solids by means of a rising gas comprises a casing within which horizontal or inclined shelves are vertically staggered on alternately opposite sides, the shelves extending halfway across said casing, and inlet and outlet means for the gas and for the granular materials being provided at the appropriate ends of the casing. The flow of the granular material is such that it falls freely in thin sheets from one shelf to the next whereby there is a relatively low pressure drop in the gas as it passes through the chamber. The outlet of said chamber is so constructed that the material accumulates at the base thereof effectively to form a gas seal. Two heat exchangers may be arranged one above the other (Fig. 2 not shown) and the granular material e.g. sand, crushed refractories, metal oxides, garnet or zircon said acts as a heat carrier between hot waste gases passing through the upper heat exchanger and air for combustion passing through the lower heat exchanger. The air for combustion is preheated by the sand &c. when it transports the latter from the outlet of the lower heat exchanger to the inlet of the upper heat exchanger via a cyclone separator. For drying wet sand a combustion zone is arranged in the middle of the heat exchanger as shown, the fuel being fed directly to the zone and the air for combustion being admitted at the base of the heat exchanger. The wet sand is dried by (a) removing hot sand from the heat exchanger just above the combustion zone mixing the wet sand therewith and returning the mixture to the heat exchanger just below the combustion zone or (b) mixing the wet sand, by means of a special shelf, with the hot sand in the area just below the combustion zone; or (c) feeding the wet sand directly into the top of the heat exchanger. In cases (a) and (b) a portion of the dry sand is separated off and recycled through the heat exchanger. The time of stay of the sand may be increased by withdrawing the sand from a lower shelf and recycling it through a higher shelf. The two heat exchanger combination is also said to be suitable for absorption-desorption processes and stripping-regenerating operations by provision of heating elements or tubes within the heat exchanger or by passing a heat transfer fluid through hollow shelves.

Title: Improvements in or relating to the rolling of strip
Inventor: WISTREICH JOHN GEORGE
IPC: B21B37/38
Filed: 1965-06-15
Abstract: 1,145,836. Automatic control of rolling mills. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Sept. 15, 1966 [June 15, 1965], No. 25225/65. Heading G3R. The gauge and shape of rolled strip are automatically maintained constant by the control system shown in the Figure, in which a shape sensor 8 generally similar to that disclosed in Specification 1,138,822 supplies a signal to a computer 9 to regulate the roll gap setting by screwdown motors 10, and gauge control is effected in a manner generally similar to that described in Specification 681, 373 by feeding signals from detectors 1, 2, respectively representative of the rolling force and roll gap setting, to a computer 4 which controls the strip tension through a torque regulator 5, drive motor(s) 6 and coiler or uncoiler 7. Screwdown adjustment produced by a shape error signal brings the gauge control into operation in such a sense as to assist reduction of the original shape error and maintain the correct gauge, the operation of the gauge control being inherently faster than the shape control to prevent hunting. In a similar embodiment, Fig. 4 (not shown)applicable to discontinuous adjustments of screwdown, the computer 9 is supplied with additional signals representative of rolling force and roll gap setting thereby altering the considerations upon which the shape control is based. Other modifications include computing (by member 4) the current rolled gauge using an equation for mean gauge (instead of desired gauge) or using an X-ray sensor in close proximity to the shape sensor 8 to provide a direct measure of the outgoing gauge, members 1, 2, 4 then being dispensed with and the regulator 5 being controlled by the gauge error signal. If back-up and work rolls are used with hydraulic jacks therebetween, Fig. 2 (not shown), the shape error signal may be used to vary the mutual flattening of the work and back-up rolls instead of varying the screwdown. The invention may employ separate gauge and shape control systems individually acting in the above described ways providing that the systems are compatible, i.e. the action of one tends to correct the error of the other and their response rates are such as to avoid the occurrence of hunting. Typical compatible and incompatible systems are discussed in the Specification. The invention is applicable to the final stage of rolling and should be preceded by a predictive or negative feedback automatic gauge control system to deal with excessive gauge errors.
