Title: Improvements relating to centrifugal spinning machines for the production of artificial silk
IPC: D01D7/02
Filed: 1928-09-12
Abstract: 297,424. Bemberg Akt.-Ges., J. P. Sept. 21, 1927, [Convention date]. Void [Pubdished under Sect. 91 of the Acts]. Apparatus for making filaments.- To obtain an increased output from a spinning frame, the number of spinning elements 1, which are arranged in a row, is increased and the necessarily increased number of centrifuges 8, 8<1> are arranged in two or more rows. It is convenient so to arrange the rows of centrifuges that those of one row are opposite the gaps of an adjacent row as shown in Fig. 5. The rows of centrifuges may also be placed on both sides of the rows of spinning elements, or the centrifuges may be arranged in the form of steps sloping upwards. The guide rollers or equivalent devices 6, 6<1> associated with the centrifuges may be accommodated on a single shaft, as shown in Fig. 1, in which case the threads travel in an oblique direction to the centrifuges, or they may be on shafts corresponding in number with the rows of centrifuges, the threads then falling vertically. In a stretchspinning frame, the threads pass through - acidifying-baths 5, Figs. 3 and 4, and may be then either wrapped around rollers 6, 6<1>, Fig. 3, or they may be led round rollers 10, Fig. 4, up to the rollers 6, 6<1>, in which case one of the latter rollers may be mounted on a transverse shaft as shown. The latter arrangement gives a longer path of travel and a more uniform tension on the thread. Specification 246,335 is referred to.

Title: Improvements in fertilizer distributing apparatus
IPC: A01C15/00
Filed: 1928-09-13
Abstract: 318,399. International Harvester Co. of Great Britain, Ltd., (International Harvester Co.). Sept. 13, 1928. Manure distributers. -A distributing - machine of the broadcast type in which fertilizer falls from the whole width of the container is provided with adjustable shoots for directing it to the soil in definite streams and on one or both s:des of the plants, the shoots being of scoop or channel-like form open on one side and arranged in pairs, and each pair being suspended in the form of an inverted V. Beneath the container or hopper 1 is mounted a rod 4 carrying alternating pairs of long shoots 5 and pairs of short shoots 6 with single shoots 7 at the ends. The shoots are comparatively wide and of rectangular or U-shaped section, one of the sides being of less height than the other. The shoots are adjustably pivoted on brackets 27 movable along the rod 4 and secured by collars 30 and screws 31. The rod 4 passes through loops 8 and is movable longitudinally by means of a lever 9 having handles 11. The hopper bottom may consist of transversely slotted members 14, 15 between which two screen-like members 16 are reciprocated by means of bevel gearing 12, 13, cranks 19, connecting rods 21, slotted rocking arms 20, and connecting-rods 17, the discharge being varied by moving the ends of the rods 17 along the rocking arms 20 by mca.'ns of a lever 24 provided with a scale for indicating its position. The member 15 and the rod 4 and shoots 5, 6, 7 may be removed together by loosening hooked bolts and withdrawing them sideways from slotted holders 36 on the member 15. With the arrangement of shoots shown in Fig. 1, the fertilizer falls into all shoots but that from the short shoots 6 passes into the long shoots 5 which deliver on both sides of a row of plants, the short shoots forming a shield for the foliage. For delivering the fertilizer between two rows of plants, the short shoots may be removed. Fig. 7 shows an arrangement for depositing on one side only of plants, long and short shoots being connected together in pairs. The shoots may be turned about supporting bolts to vary the angle between them and thus the distance between the streams of fertilizer. The shoots may be guided along the rows by moving the lever 9. A limited number of the slots may be linked together for 'operation by the lever 9. The shoots are free to ride over obstructions. In machines in which the fertilizer is discharged from the front or rear of the hopper by rollers, chains, &c., the rod 4 is carried by a. support projecting forwardly or rearwardly from the bottom of the hopper.

High-frequency energy is fed to or from the resonators through coupling probes or discs 33 from or to coaxial lines 34.
Patent GB-775127-A (GB)
Title: An improved electrostrictive actuator
IPC: H01H57/00
Filed: 1954-09-13
Abstract: 775,127. Electrostatic switches; thermal switches. ELECTRICAL MACHINERY MFG. CO. Sept. 13, 1954 [Sept. 17, 1953], No. 26414/54. Class 38(5) [Also in Group XL(b)]  A relay has a bending electrostrictive member mounted at its ends, the movement of an intermediate portion of the members being used to actuate the relay contacts. In Fig. 6, the moving contact 73 is mounted on an arm 71 pivoted at 74 and biased counter-clockwise by a spring 81, the contact 73 co-operating with fixed contacts 80, 88. A part 70 of the arm 71 extends through a slot in a link 65 attached to the centre of the electrostrictive member 41. The latter comprises two electrostrictive elements 43, 44 arranged on opposite sides of a brass electrode 42 having tongues 48, 49 engaging spring clips 17, 33. The latter is adjustable by means of a screw 37. The member 41 bends downwards when a p.d. is applied between electrode 42 and the outer surface 46 of element 44, thus separating contacts 73, 80 and closing 73, 88. In a modification, Fig. 8, two oppositely acting electrostrictive elements 102, 103 are separately mounted and connected by links 110, 111 to points on the contact arm 108 on either side of the pivot 113 thereof. This arrangement prevents operation by shocks perpendicular to the planes of the elements 102, 103. In a further modification, Fig. 9, an electrostrictive element 128 is attached to the underside of an iron-nickel alloy electrode 127 to form a bender unit connected to the contact arm 130 by a link 129, as in Fig. 6. An adjusting screw 133 engages a part of the support clip 124 of the unit. If a p.d. is applied between the electrode 127 and the outer surface 132 of the element 128, the unit will bend upwards but if at the same time the unit is subjected to heating it will tend to bend downwardly due to unequal expansion of element 128 and electrode 127. Thus the operating temperature depends on the magnitude of the p.d. Alternatively, the electrode 127 may be of brass so that the thermal expansion aids deflection by the applied p.d. Specification 773,888 is referred to.

Filed: 1961-07-21
Abstract: 927,196. Nuclear power plant. SULZER FRERES S.A. July 21, 1961 [Aug. 19, 1960], No. 26616/61. Addition to 897,416. Class 39 (4). [Also in Group XIII] In a plant in which vapour is superheated in a reactor and is then used to generate more vapour for superheating in the reactor, two or more evaporators are used, generating vapour at different pressures which vapour is brought to a common pressure before superheating. In Fig. 1 low- and high-pressure evaporators 2 and 3 generate steam by heat exchange with steam superheated in reactor 1. The high-pressure steam drives a turbine 13 coupled to a compressor 10 which compresses the low-pressure steam; all the steam is thus brought to the same pressure and is passed in one stream through the reactor. A thermopump may be used instead of the turbine and compressor. The superheated steam need not heat both evaporators on each pass through the reactor, but may by-pass the low-pressure evaporator. In another arrangement compressor 10 is used to compress steam which has already been superheated and used in the evaporators, thus restoring pressure lost by resistance to flow; there are thus three streams of steam to be mixed: from evaporator 2, turbine 13 and compressor 10.
