Title: Improved luffing crane mechanism
IPC: B66C23/52
Filed: 1960-05-06
Abstract: 888,550. Preventing load of crane from swinging. ALLMANNA SVENSKA ELEKTRISKA A.B. May 6, 1960 [May 8, 1959], No. 16077/60. Class 78 (4). A level luffing crane having a boom 7, Fig. 2, and winch drums 1, 3 for hoisting and luffing cables respectively all mounted on a turn-table 5 has two load-carrying cables 13, 14, Fig. 1, which are arranged in a three-point suspension 16, 21, 22 at the end of the boom. These cables pass round a sheave 19, 20 and each has at least one end attached to a drum 12 which is mounted on the boom and rotated by the hoist cable 2. As shown, both ends of cables 13, 14 are attached to the drum 12 so that the hoisting cable winds in both ends of cables 13, 14 by rotating the drum 12. The sheaves 20, 21 are widely spaced laterally to form, with the sheave 15, 16, the three-point suspension which prevents swinging of the load. In a second embodiment in which only one end of the load-carrying cables is fixed to the drum 12 those sections of the drum 12 on to which cables 13, 14 are wound have a diameter twice that of the part of the drum taking up the hoist-cable 2, the opposite ends of cables 13, 14 being fastened to the boom at the point of attachment of sheaves 15, 16. In a further modification, the sheaves 15, 16, Fig. 1, may be mounted directly on the boom 7 between the drum 12 and sheaves 9 whilst the sheaves 21, 22 could be longitudinally spaced on the boom in relation to the position of sheaves 15, 16, the sheaves 21, 22 being mounted on one or two extensions of the boom, preferably at the tip. As described, the boom is of ladder construction tapering towards its outer end. A small electric motor 23 may ensure positive lowering of the load hook if its own or an added weight is insufficient.

Title: Process of and apparatus for gasifying pulverulent fuels
IPC: C10J3/46
Filed: 1950-06-28
Abstract: 679,996. Generating water gas. METALLGES. AKT.- GES. June 28, 1950 [July 8, 1949], No. 16191/50. Class 55 (i). In a process for the continuous production of water gas wherein steam is passed up through a fluidized bed of finely divided fuel, the heat requirements of the reaction are met by admitting a heated finely divided heat carrier to the bed entraining some of the fuel therefrom and being conveyed upwards in a stream of air in which the fuel burns, thus reheating the carrier which, after separation from combustion gas, is returned to the fluidized bed. In the form shown, the apparatus consists of a refractory lined shell 15, divided internally into a gasifying chamber 1, a combustion and conveyer shaft 2 and a dust separating chamber 4, the latter being connected to the chamber 1 by a downcomer shaft 5. The fuel bed in the chamber 1 is supported on a perforated grate 7 beneath which superheated steam with or without the addition of oxygen or air, is admitted through an inlet 6, the steam fluidizing and gasifying the fuel and the water gas produced discharging through an outlet 9. An overflow 11 maintains the level of the bed constant. In operation, air is blown up through shaft 2 and carries with it material overflowing from the fuel bed through conduits 3 at each side of the shaft, the flow of material being controlled by dampers 12. The material consists mainly of ash with up to 30 per cent admixture of fuel from the bed, this fuel burning in shaft 2 and so raising the temperature of the ash to about 1200‹ C. The hot ash separates in space 4, combustion gases escaping through outlet 14, and passes down shaft 5 meeting a stream of raw fuel admitted through inlet 8. The mixture passes into chamber 1, where the fuel is gasified by the incoming steam. When the ash from the fuel is unsuitable or insufficient in quantity for use as a heat carrier, substances such as sand, alumina, &c. may be added to the fuel. Provision is made for the automatic control of steam and air admission and watergas discharge as determined by pressure conditions in the apparatus. The process may be operated at pressures between 2 and 20 atmospheres, when a water-gas with an increased methane content which renders it suitable for use as town's gas is obtained.

Filed: 1929-05-27
Abstract: 329,178. Kumpmann, K., Kumpmann, W., and Kumpmann,K. May 27, 1929. Tapping nuts.-In a curved shank tapping-machine, a device is provided to relieve the threads of the taps from the duty of feeding the nuts along the shank. The tap d is enclosed in a head a on a revolving shaft b. The nut channel in the head has a diameter approximately equal to that of the nuts along its straight portion, but widens out at the curved portion. A steel plate h is pivotally mounted on a stud g and is resiliently held against the end of the string of nuts by a spring l, the lower edge of the plate being inclined to form a point which is situated opposite the last nut y of the string, tension being adjusted by a screw k and a lever i. Bows q held together by a spring v and pivotally mounted on bolts r meet to form a circular hole which acts as a centring device for the tap. When the head returns after tapping a nut, the nut last tapped engages the bows and then holds the tap and the nuts thereon stationary until the relative position shown in Fig. 3 is attained. The bows then yield and allow the nut to pass. At the same time the leading nut is freed from a shoulder m and falls from the machine, the succeeding nuts being retained by the plate h. On the next tapping operation the bows feed the nuts one step along the shank ready to repeat the cycle.

Abstract: 466,071. High-frequency transmission. STANDARD TELEPHONES & CABLES, Ltd. June 12, 1936, No. 16507. Convention date, Sept. 18, 1935. Drawings to Specification. [Class 40 (iv)] [Also in Group XL] In the transmission of signals covering a wide frequency band such as 0 .. 2000 Kc., the. lower part of the band (say) 0 .. 300 Kc. is shifted to a position above the highest frequency in the original band. Where, as in television, the energy of the signals is concentrated in regions centred on harmonics of a base frequency, the intervening regions being void of useful signals, the point of division between the shifted and unshifted ports of the band is put in one of the void regions. At the receiving end the shifted band may be passed through a phase corrector before being restored to its original position. Alternatively an anticipatory correction is applied at the sending end. The invention is useful in the distribution of television signals over a network of co-axial distribution cables including amplifying sub-distributing stations in which a single amplifier feeds several branch lines. The feeders connected to the terminal apparatus may be associated with the main cable by transformers or by direct con. nection.

Title: Improvements in locking devices for preventing thefts of vehicles and for locking doors, boxes and the like
IPC: B62H5/06
Filed: 1922-06-15
Abstract: 201,346. Cappellari, A., and Donzelli, L. June 15, 1922. Locks, permutation.-In a permutation device suitable for locking the steering shaft of a vehicle or velocipede and also for locking doors, boxes, &c., a spring-pressed bolt carried by a sliding member can only be retracted when a perforated sleeve and a setting pin have been correctly positioned. Fig. 1 shows the device applied to a cycle. The bolt 21 carried by the member 17 sliding in the cylindrical casing 18 secured to the tube 2 by members 3, 4, 4<1>, engages one of a pair of diametrically opposite holes 38 in the collar 36 rigid with the steering shaft 37. to lock the front wheel at an angle of 90‹ with the axis of the cycle. The member 17 has a shank 16 of rectangular cross-section, the bevelled end of which registers with a slot in the fixed cylindrical casing 5 also secured to the member 4<1>. The bolt 21 is blocked against withdrawal until a cylinder 7 rotatable in the casing 5, is set to align a notch with the shank 16, and the pin 28 is set to allow the shank 16 to push the block 9 upwards, the pin 28<1> entering the slot 12'. The " set " position is shown in Fig. 1. The cylinder 7 is set by rotating a cap 51 which rotates the member 26 carrying the arm 28 with its pin 28<1> by reason of the engagement of the spring-pressed bevel-nosed pin 40 in the depression 55 in the member 26. The pin 28<1> engages a projection 8 inside the cylinder 7 and rotates it. Rotation of the cap 51 in the opposite direction sets the pin 28<1> above the recess 12<1> in the member 9, which rotates with the cylinder 7 but can slide axially inside the cylinder by reason of the engagement of the projectors 13 with slots 14. The cap 51 has three pointers, two of which, 26b, 26c, are shown, which move over a graduated cover plate 6. Only one pointer is used in setting. The cylinder 7 may have three holes, 15a, 15b, 15c, corresponding to three positions which the shank 16 may be set by partial rotation of the cylindrical member 17 before screwing in its pair of side knobs for operation. The member 17 may be mounted to slide in the tube 2 instead of in a casing 18 rigid therewith. In this case, the casing 5 is also dispensed with and the member 9 slides on, and the member 26 turns on; a pivot passing through the tube 2. To change the combination, the screw 52 is loosened, relaxing the spring 39 and allowing the bevelled pin 40 to leave the depressions 55 in the member 26 as the block 51 is turned to the new combination, when the screw 52 is tightened up again.

Abstract: 390,972. Starting prime movers. SIMMS MOTOR UNITS, Ltd., Percy Buildings, Gresse Street, Rathbone Place, and LOCK, A. C., 30, Dulwich Common, both in London. June 13, 1932, No. 16723. [Class 38 (iv).] In an electric starter in which a toothed driving member 6 is moved axially into and out of engagement with a toothed engine member 8 by a helical connection 7 between the driving member 6 and the spindle of the starting motor, the initial movement of a switch completes the motor circuit through a resistance and after the driving member engages the member 8 the switch is released by the driving member and short-circuits the resistance. As shown, the member 6 is a pinion having a pin engaging a helical slot 7 in a sleeve 3 driven through a spring 'from the spindle 2. The switch comprises a solenoid 27, the core 25 having an extension 24 carrying a carbon contact disc 31 and a dished metal contact member 40, normally held in the position shown by springs 38, 39. On closing the circuit of the solenoid, the movement of the core 25 brings the disc 31 into contact with arcuate carbon contacts 43, 44 of high resistance in the circuit of the starting-motor. In this position, a brake block 11 on a lever 12 is held in engagement with a collar 10 on the pinion 6, a hook 29 on the end of the lever 12 engaging a hooked pawl 21 pivoted at 22 to a head 23 on the extension 24 of the core 25. The position of the pawl is determined by a spring 28 and an adjusting screw 29. When the axial movement of the pinion into engagement with the engine gear 8 is completed, the collar 10 clears the brake block 11 and allows the solenoid to bring the member 40 into engagement with copper contacts 46, 47, cutting out the resistance 43, 44 from the motor circuit and allowing the motor to speed up. In this position the pawl 20 rides over the end of the lever 12, which is returned by a spring 17.
