Title: Improvements in and relating to Arrangements for Ensuring Safety in Winding Mine Cages.
Inventor: MORGANS REES
IPC: B66B5/28
Filed: 1916-06-06
Abstract: 106,347. Morgans, R. June 6, 1916. Winding-gear for collieries and the like; overwinding, preventing; sustaining at limit of wind. -Safety apparatus for preventing falling of the cages in mine shafts in the event of breakage of a winding-rope, or of an overwind, comprises duplicate winding-ropes each attached to both cages and driven by pulleys or sheaves on the winding-engine shaft; buffer arresting-devices are arranged at the bottom of the shaft, so that, if one cage is allowed to descend below the normal level, the ropes are slackened and lose their grip on the driving-pulleys, thus preventing the upper cage from being wound into the head-gear. As shown in Fig. 2, the ropes C are each attached to both cages d, D and are led round double head-sheaves b, B to the driving- pulleys a, A. As a modification, the driving- pulleys may be supported in the head-gear. At the bottom of the shaft, pairs of spring-supported inclined slides X gradually arrest the lower cage when it passes the level W, the upper cage then resting on pawls S in the head-gear, owing to the relaxation of the tension of the winding-ropes. The ropes C are attached to a plate F, Fig. 4, to which the bridle-chains E of the cage are attached by a shackle G<3>, and two auxiliary chains H are provided to support the cage in case of fracture of the shackle G<3>.

Abstract: 856,512. Forced-flow steam boilers. SPENCER - BONECOURT - CLARKSON Ltd. March 13, 1959 [March 13, 1958], No. 8075/58. Class 123(2) A tubulous heat exchange unit for a forced-circulation steam boiler comprises a bank of similar tubes 3 of zig-zag form which extend across a rectangular metal casing 6 defining a gas-flow passage and which are connected between upright inlet and outlet headers 4, 5 located adjacent the sides of a front face 30 of the casing 6, the return bends of adjacent tubes, at the sides of the bank, being in staggered relationship so that adjacent limbs 21 of the tubes are mutually disposed in crosswise fashion. The plane containing the longitudinal axes of the limbs 21 of each tube 3 is inclined to the longitudinal axes of the distributer and collector headers 4, 5. The latter compise outer trough-shaped casings 9, 16 having base flanges 10, 17 connected respectively to rectangular tube plates 11, 18 provided with pairs of vertical rows of openings 15A, 15B and 20A 20B into which one expanded the corresponding vertically staggered ends of the tubes 3. A curved baffle 12, welded at its upper end and its edges to the inner surface of the distributer casing 9, has its lower end spaced from the corresponding end of the casing and divides the latter longitudinally into inlet and outlet spaces, slots 14 being provided in the baffle 12 opposite each pair of openings 15A, 15B. The ends of the tubes 3 extend through end plates 31, 32 secured to the casing front wall 30 the spaces above and below the plates being filled respectively with plates 37. 38. During assembly the inclination of the tubes depends upon the required spacing of the headers 4, 5, the casing 6 being dimensioned accordingly and if desired being lined internally with refraction material. A forced-flow steam generator, Fig. 3 comprises five serially connected heat exchange units two 50, 51, being accommodated in a combustion gas section 43 having an oil burner 45, a roof 61, and baffles 49, 60 and the remaining three units 68...70 being housed in an upper wasteheat section 42 which has a roof 79, baffles 77, 78, and an exhaust outlet 80. The section 43 is supplied e.g. with exhaust gases from a gas turbine through a duct 66 a corresponding opening being formed in the casing adjacent the heat exchanger 68 opposite the duct 66. A combustion gas section outlet 61A, between a side wall 47 and the roof 61 and leading to a damper controlled exhaust pass 83A also communicates, through a parallel opening 64 controlled by a damper 65, with the wasteheat section 42. A forced circulation pump 83 delivers water, from a downcomer 82 connected to an upper steam and water drum 81, to the lowest heat exchange unit 50, the uppermost unit 70 being connected to the steam space of the drum 81. When either section 42, or 43 is operated on its own the remaining heat exchange units 68...70 can be by-passed.

Patent GB-704168-A (GB)
Title: Improved braking system for aircraft
Inventor: DEWAR DOUGLAS
IPC: B60T8/17
Filed: 1951-04-07
Abstract: 704,168. Aircraft brakes. DUNLOP RUBBER CO., Ltd. March 14, 1952 [April 7, 1951], No. 8116/51. Class 103(1) The invention comprises an improvement in the braking system for aircraft described in Specifications 676,708 and 683,490 wherein means are provided for preventing skidding of the wheels during landing and for rendering the skid prevention device inoperative until the wheels have been rotated on landing. This latter function is carried out by arranging for the lowering movement of the undercarriage to operate a hydraulic cylinder, located at the part 13 shown in the figure, the piston of which operates a cocking device which prevents the skid prevention means operating until the rotation of the wheels has centrifugally released a valve locking mechanism. Such a system, as described in Specification 683,490 does not allow for the occasion when the aircraft touches down and the pilot, due to misjudgement or other reasons, has to take off immediately and repeat his approach circuit. Continuous correct operation under the above conditions is allowed for, according to the present system, by connecting the cylinder 13 which operates the cocking mechanism for the skid prevention means, to a pressure supply, branched off the main supply, and by controlling the pressure in the cylinder 13 by means of interlinked inlet and exhaust valves 194, 195, operated by a solenoid. The solenoid has a coil 22 which is energized to open inlet valve 194 and close exhaust valve 195 only if two switches 25 and 26 are closed respectively by closure of the engine throttle controls and by' lowering of the undercarriage mechanism. Thus if the pilot reopens the throttle control to repeat an airfield circuit the cocking device will be reset when he again throttles back on a fresh landing run in. The main control valve 23 may be of the type described in Specifications 507,162 and 525,266.

Abstract: 961,680. Nesting and stacking trays. W. H. LOCKWOOD. March 7, 1961 [March 18, 1960], No. 8224/61. Heading B8P. A container 30 for tiering and nesting with other like containers has a bottom 31 rigidly connected by side walls 33 to upper edges 38 in which are formed upper tiering support portions 40 which are vertically above corresponding lower tiering support portions 44 in the bottom. The container is dimensioned to allow it to enter, or be moved relative to, a lower container, while in the tiering position the lower portions 44 of the upper container nest upon corresponding upper portions 40 of the lower container. The bottom 31 is rectangular, or trapezoidal or other forms, and its edges forming the bottom periphery 32 are not parallel to the corresponding edges in the upper periphery 36, and the side walls 33 therefore each include a warped sheet, like member 34. This construction permits the containers to be moved from the tiering to the nesting position by a lifting, turning and lowering movement. The portions 40 and 44 each include a laterally extending protrusion 41 or 45, part 41 being in the form of an opening notch with outwardly opening portion 42a which receives the hook-like protrusion 45 on the upper container. Portion 42b and notch 46 then interlock as in egg carton partitions (see Fig. 33). Other forms of the container are described in which the bottom edges of the container merely rest on the notches in the top edge of the lower container, while the bottom may have different shapes and the number and position of the notches is varied. The sheet material used may be sheet metal, moulded plastic, wood, plastics coated plywood &c. One form described has open wire walls.

Title: Machine for wrapping and packaging articles
IPC: B65B25/04
Filed: 1966-02-24
Abstract: 1,089,312. Packaging-machines. E. FABBRI. Feb. 24, 1966 [Feb. 24, 1965], No. 8226/66. Divided out of 995,834. Heading B8C. [Also in Divisions B5 and B6] The apparatus described in the parent Specification is modified in that a tensioning roller D, Fig. 1, is provided to draw back the upper web S2 against the conveying direction after welding the two webs S1, S2 together in front of the articles being packaged, so that the leading end of the lower web S1 is drawn above at least part of the articles, e.g. fruit F, thereby forming a tighter package. The web S2 is fed from a roll R2 round the tensioning roller D, rotatably mounted at the end of a pair of freely swinging arms 21, and between a roller B and pinch rollers 25. These latter rollers are cam-operated to move in and out of engagement with the roller B. At the end of each wrapping operation, Fig. 2 (not shown), the ends of the webs S1, S2 are welded together at a conveyer bar 3 by a welding blade L. During the welding operation, the web S2 is held between the now stationary driving roller B and pinch rollers 25. After a predetermined time, the conveyer and driving roller B are restarted, the movement of the conveyer causing the rollers 25 to be lifted clear of the web S2 so that it can be pulled back against the fruit F by the action of the tensioning roller D, Fig. 3 (not shown). The conveyer is then stopped and simultaneously the web is clamped between the rollers B and 25 for the next welding operation. The welding blade L, Fig. 4a (not shown), comprises a hollow wedge-shaped metallic piece, conventionally heated, which is reciprocated downwards to co-operate with a conveyer bar 3, of upwardly opening channel section, each time the conveyer chains are stopped, to form two parallel weld lines W1, W2 and simultaneously to sever the webs between these lines. In place of the rakes 4, 6, rectangular frames (304), (306), Fig. 10 ((not shown), may be used.

Abstract: 896,554. Unattended repeaters. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. March 8, 1960 [March 10, 1959], No. 8259/59. Class 40 (4). A repeater station, such as a buried transistorized repeater on a cable, is provided with a test point T in a readily accessible position and having a low impedance between its two terminals so that poor insulation between the terminals does not appreciably prejudice operation of the station. The output of the repeater amplifier is connected to the primary of a transformer TR having the centre of its secondary connected to earth through an impedance Z which compensates for the impedance of the primary circuit. Resistor RA is considerably greater than resistor RB, and their combined value is slightly greater than the resistance RO of the line L1, L2. One of the test terminals T is connected to earth and the other is connected through a further resistor RC to the junction of resistors RA and RB. If a pilot signal is used for gain regulation, resistors RD and RE are added, forming with resistors RA and RB an attenuator. The output from terminals T1 and T2 is supplied to the pilot filter and thence through an amplifier to the gain regulator. Specifications 840,666 and 864,442 are referred to.
