Abstract: 989,011. Electric correspondence control systems. BROWN, BOVERI &CO. Ltd. Feb.16, 1962 [Feb. 16, 1961], No. 6050/62. Heading G1N. The temperature at different parts of e,g. a steam turbine are determined electrically and the maximum difference recorded as indicative of the maximum stress produced due to temperature difference, whereby the conditions of loading &c. may be manually or automatically controlled to ensure that the maximum permissible stress is not exceeded. The temperatures are measured by thermocouples 3, 4, 5 (Fig. 2) located in a probe mounted on the stator of the machine, with thermocouple 3 measuring the maximum temperature, 4 the minimum temperature and 5 the average temperature. The difference between the outputs of thermocouples 3, 4, indicative of the actual thermal stress, is amplified at 8, modified in accordance with additional stress dependent on the average temperature or the temperatures difference, and indicated by line 10 on a recording instrument 7. The maximum permissible stress is obtained by amplifying at 9 the signal from thermocouple 5, producing limit lines 11a, 11b on meter 7 for the measured stress line 10. The machine operating conditions can be automatically controlled by a regulator 13 fed with the signals U 1  representing the actual stress, U 2  the maximum permissible stress, #U the permitted tolerance, dU 1  the rate of change of stress &c. dt

Title: Improved crimped artificial filaments
Inventor: RAJCHENBAUM NIUMA BENJAMIN
IPC: C07C51/275
Filed: 1954-03-03
Abstract: 759,070. Crimping yarns and filaments. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Feb. 16, 1955 [March 3, 1954], No. 6201/54. Class 120 (3). Drawn filaments of a synthetic linear polymer, e.g. polymethylene terephthalates, polyamides, in the form of tow or yarn, are doubly crimped as by passage through a stuffer-box (e.g. as described in U.S.A. Specification 2,311,174) or gear-wheel crimper; optionally, heat-setting the crimp as by superheated steam, or dry heat by contact with hot surfaces, radiation heat, or heating by convection or conduction, and drying as by hot air, if necessary ; then subjecting the crimped filaments to one or more further crimping processes (which may be similar to the first) while under tension, as may be achieved by passage of the filaments over tensioning-pins, not exceeding that required to straighten the crimps applied during the preceding process. The filaments may be fed directly from one crimping apparatus to the next and rotated therebetween so that the additional crimping occurs in a different plane from that of the initial crimp, or yarn may be wound on bobbins, or tow fed into cans or wound on large beams, after each crimping step. The walls of the stufferbox or the gear-wheels may be heated or the tow may be heated prior to entry thereto. On emerging from the final crimping operation, a heat-set and dried tow spreads laterally into a sheet of separated filaments. this action being assisted by electrostatic charges which accumulate on the filaments, and in this form the filaments are suitable for dressing, as with lubricants, and subsequent stapling by cutting.

Title: Improvements in machines for washing clothes
IPC: D06F13/00
Filed: 1953-03-06
Abstract: 728,544. Washing-machines. WALTON WASHING MACHINE CORPORATION. March 6, 1953 [Sept. 13, 1952], No. 6291/53. Class 138 (2). A clothes washer unit, for mounting in a container holding liquid and articles to be washed, comprises a hollow clothes engaging member 36 which is perforated over substantially the whole of its immersed surface, and is throughout of cross-sectional area at least as great as that of its lower end, driving mechanism for reciprocating the member 36 vertically, and a pump for withdrawing liquid from the interior of the member 36 and expelling it into the container over the periphery of the lower end of the member 36, thereby causing liquid from the container to cascade through the perforations to replace the expelled liquid and at the same time to carry the articles towards the member 36 which has external gripping surfaces adapted on each down stroke to push articles downwardly towards the output stream of the pump. Fig. 1 shows a portable unit in which the clothes engaging member 36 is reciprocated vertically by means of a shaft 16 provided with a reverse slotted spiral cam 30 in which rides a cam follower 32 connected to the member 36 by means of a spider 34. The pump comprises an impeller 18 fixed to the shaft 16 which is rotated by an electric motor 14. The unit is supported by three suction cups 26 mounted on a hollow cylinder 24 to which are secured vertical rods 20 supporting the motor 14. Annular ribs 42 on the member 36 form the clothes engaging surfaces. Fig. 3 shows a modification in which the clothes engaging member comprises a wire mesh basket 36a, and the impeller 18 is replaced by a single acting force pump moving with the basket 36a and comprising a rubber or like disc 44 which yields (as shown in broken lines) on the up-stroke but is pressed against a perforated annular support 48 on the down-stroke. In another modification (Fig. 4), the clothes engaging member 36b is generally cylindrical but has cylindrical portions of progressively smaller diameter at its lower end. The suction cups 26 are replaced by an annular rubber ring 56 and the supporting cylinder 24b has liquid outlet openings in its side walls and liquid admitting openings 58 in its bottom wall. The impeller draws liquid not only from within the member 24b but also through the openings 58, the suction produced thereby holding the unit against overturning. In a further modification (Figs. 5, 6, not shown), the clothes engaging member is rotationally oscillated as well as vertically reciprocated. The supporting rods (corresponding to rods 20 in Fig. 1) are arranged spirally, and the arms of the spider supporting the clothes engaging member are provided with openings to accommodate these rods and be guided thereby. In still further modifications (not shown), the motor may be made waterproof and mounted at the bottom of the unit, or the unit may be permanently mounted in its own tub. Specification 555,294 is referred to.

Title: A device for automatically operating the fuel injection timing gear of the injectionpump of an internal combustion engine
IPC: F02D1/00
Filed: 1951-03-16
Abstract: 681,596. Cooling cylinders. DECKEL, H., and DECKEL, F. W. March 16, 1951 [July 6, 1950]. No. 6390/51. Class 7 (ii) [Also in Group XXIX] In a device, such as a membrane 30, for auto, matically controlling the fuel-injection timing-gear of an internal-combustion engine, not shown, by the pressure of the engine cooling medium which pressure is dependent upon engine speed and the device being attachable to the coolant circulating, pump 14 in place of the pump cover, it is arranged that the working space 48 of the device 30 consti tutes a chamber adjoining the working chamber 1 of the pump. A casing 10 houses the engine-driven pump 14 the working chamber 18 of which communicates with the engine cooling system by a pipe, not shown; the iront of the casing 10 is closed by a plate 20 in turn closed by a cover 26 between which latter members is secured the spring-loaded membrane 30, having the centre portion connected by washers 32 to a flanged bush 36 that is fixed to a shaft 38. The shaft 38 is connected by rods or levers with the fuelinjection pump timing gear. With the engine inoperative the apparatus is in the position shown with the timing gear at retard; when the engine is functioning the pressure of the cooling water in the pump chamber 18 will increase as the engine speed increases and since the pressure in chamber 18 acts upon the membrane 30 due to openings 50 in the closing plate 20 the shaft 38 is moved rightwardly to advance the timing in dependence upon engine speed, a stop 52 defining the limit of such movement. At least one of the openings 50 is arranged at the lowest point in the membrane working space 48 so that when the coolant is drained from the engine this space is simultaneously and automatically emptied. In a modification, the main delivery pipe from the pump to the cooling system is throttled by a valve member directly connected to the, membrane in order to modify the operating characteristics of the timing control so that it is possible, for example when the engine is idling on an no-load, to obtain a pressure rise in the membrane working space which decreases with increasing engine speed and finally vanishes so that the timing is again entirely dependent upon engine speed. In a further modification, the membrane is replaced by a bellows, the operating shaft is no longer coaxial with the pump shaft and the bellows is loaded with two springs, the stronger spring only becoming effective after a predetermined amount of rightward movement of the shaft.

Abstract: 728,909. Machinery guards. INDUSTRIAL GUARDING EQUIPMENT, Ltd. June 8, 1953 [March 13, 1952], No. 6486/52. Class 80 (4). A guard 8 for a manually-operated press is pivotally carried by two pairs of parallel'links 13, 14 pivoted to the press frame and connected to the slide 6, so that the guard descends and ascends faster than the slide, by a rod 29 which also operates a trip mechanism to stop the slide's descent should the guard 8 meet an obstruction, such as an operator's hand. The rod 29 has a slotted connection with the links 13 and is normally held in a groove of a housing 17 on the slide 6 by an abutment on a spring- loaded bolt 22, Fig. 5, which is normally in a retracted position so that the rod 29 rises and falls with the slide. On obstruction of the guard's descent, however, the rod 29 is raised relatively to the housing into the position shown and the bolt 22 is shot into engagement with a fixed .rack 31, thereby stopping the slide. A resetting handle 24 passes through a slot in the housing which limits the bolt's movement.

Title: An improved method of and apparatus for recovering sulphur dioxide from furnace gases or other gases containing the same
IPC: C01B17/56
Filed: 1920-05-04
Abstract: 167,726. Eustis, A. H. May 4, 1920. Drying gases.-Moist sulphur dioxide gas, obtained from furnace gases &c. and cooled to deprive it of a part of its moisture, is brought into contact with liquid sulphur dioxide whereby substantially the last traces of moisture are removed. In the apparatus shown, the gas having been cooled and partly dried enters a cooler 30 from the top of which it passes to a compressor 32 which delivers it to a condenser 33, the gas being liquefied therein and passing to a storage vessel 34. Between the compressor and the condenser is interposed a trap 35 cooled by a coil 35b and containing coke and liquid sulphur dioxide; in this trap, slight liquefaction takes place and the gas is very largely dehydrated. The liquid from the trap is blown back through a valved pipe 36 into the cooler 30. The gas may be cooled before entering the compressor by a surface cooler or by the injection of a part of the liquid from the trap 35 into the inlet pipe. The compressor may be jacketed to prevent condensation at the surface and consequent corrosion. Specification 168,627, [Class 1 (ii), Inorganic compounds, other than &c.], is referred to.

Filed: 1920-03-05
Abstract: 164,145. Graham, N. W., Kellett, J. M., and Sage, C. H. March 5, 1920. Pivoted - jaw wrenches.- Wrenches of the kind in which the adjustment of the jaws is effected by'means of members each formed with a row or series of spaced holes, the holes in one member being spaced at different intervals apart from those in the other member, a locking pin being passed through coinciding holes after adjustments are constructed so that the movable members are each formed with two or more series of holes, the holes of adjacent rows being preferably staggered. As shown, the outer jaw 9 is capable of adjustment in a cradle 3 pivoted to the upper end of a handle 1 integral with the fixed inner jaw. The cradle is resiliently mounted between springs 7, 8 arranged respectively between the front of the handle 1 and an extension 6 on the cradle, and between the rear of the handle and the cradle. To adjust the distance between the jaws, the jaw 9 is secured to the cradle 3 by means of a detachable pin 17 which can be passed through either of four holes 13, 15, 14, 16 in the cradle into the desired hole of two rows of holes 12 in the shank 10 of jaw 9. To obtain adjustments corresponding to quarters of the distance between the holes 12 these two rows are staggered by a distance of a half the space between two holes, and the pairs of holes which are separated by a distance of a hole and a half are staggered to an extent of a quarter of the distance between two holes. The invention may be applied to old wrenches of a type similar to that shown but in which the shank 10 is normally screwed and adjusted by a nut. When the thread and nut are worn the nut is discarded, and holes are bored in the worm screw shank, a pin is made to engage one of these by being passed through the slot formed in the pivoted cradle to receive the adjusting nut. According to the Provisional Specification, means such as a projection on the pin engaging in a groove may be provided to prevent accidental displacement of the pin from the slot or holes.
