IPC: E01B27/13
Filed: 1971-08-20
Abstract: 1370311 Redistributing and compacting railway ballast F PLASSER 20 Aug 1971 [20 Aug 1970] 39130/71 Heading E1G Ballast lying on the sleepers 2 of a railway track on both sides of each rail 3 is levelled by plough blades 11 on a vibratory transverse beam 7 which also carries side consolidators 10-shown as penetrative plates 10a-engaging the ballast outside the sleepers, the beam 7 being (a) mounted (as by swing links 6) on a wheeled frame 5, (b) braced by tension springs 9, and (c) vibrated by an out-of-balance mechanism 8. The machine may be self-propelled or be fitted to a conventional trackworking machine, and may have rollers engaging under the rail heads to prevent tilting. Each consolidator shown comprises a penetrative plate 10a which may be angularly adjustable, Fig. 3 (not shown), and a heightadjustable surface plate 10b, the consolidator being mounted on rubber blocks 7a and loaded by springs 12. The plough blades 11 are angularly and vertically adjustable, may be followed by further plough blades 11a and a rubber-strip ballast brush (not shown), and may have rubber strips on their lower edges.

Title: Improvements in or relating to an arrangement for effecting a selective connection between a pair of lines
IPC: H04Q3/00
Filed: 1957-12-17
Abstract: 833,933. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Dec. 17, 1957 [Dec. 20, 1956], No. 39214/57. Class 40 (4). In order to effect a connection between a pair of lines each of which may be either a 2-wire line or a 4-wire line, each of the lines of that type of which there are fewer, say each of the 4-wire lines, is fitted with a hybrid transformer connected so as to present to the selector a termination of the other type, say 2-wire, and if two lines of the same type, which are both fitted with hybrids, are connected together, the operation of relays, which takes place as a result of the connection switches out the hybrid transformers. Assuming there to be fewer 4-wire lines than 2-wire, each incoming 4-wire line is equipped as shown on the left-hand side of Fig. 1, and each outgoing 4-wire line as shown on the right-hand side thereof. If such an incoming 4-wire line is connected to an outgoing 2-wire line, or if a 2-wire incoming line is connected to such an outgoing 4-wire line, the hybrid transformer in the 4-wire remains in circuit. If, however, two such 4-wire lines are connected together the relays 1, 1<1> pull up in series over. the fourth wire b2 of the link, and operate the relays 3, 3<1> which remove the respective hybrid transformers from the circuit, thus providing a direct 4-wire to 4-wire connection. An arrangement is described with reference to Fig. 2 (not shown) in which each 2-wire line is provided with a hybrid transformer, the 4-wire lines being then without hybrids.

Abstract: 1,020,248. Sewing machines. CLINTON INDUSTRIES Inc. Jan. 4, 1963, No. 39432/65. Divided out of 1, 020, 247. Heading D1G. A sewing machine comprises a feed dog movable across the path of a reciprocating needle, and a thread-cutting member movable by means in synchronism with the feed dog and also selectively movable by means relative to the feed dog. In a twin-needle, lock stitch sewing machine having combined needle and dog feeds, the feed dog 90 is fixed to a feed bar 80, one end of which carries a sleeve 82 journalled on a crank pin 79 on a crank arm 78 rigid with a feed-advance shaft 76, and the other end of which carries a forked member 87 embracing an eccentric 88 on a feed lift shaft 89. A curved lower thread-severing blade 113, slidable on a curved surface 94 in the feed dog and having a bifurcated inner end, is carried by one arm 108 of a bell crank lever pivoted at 106 to the feed dog. The other arm 107 is pivoted at 141 to one end of a link 137, the other end of which is pivoted at 143 to one arm 134 of a bell crank lever pivoted at 132 to a bracket 123 rigid with sleeve 82. Blade 113 thereby normally moves in synchronism with the feed dog. The other arm 133 is connected via a link 145 and other linkage (not shown) to the spring-biased armature of a solenoid. Energization of the latter thereby shifts blade 113 inwardly, when the bobbin threads are engaged by notches at the front of the bifurcations of blade 113 and are thereby guided into respective grooves 116 formed in the upper surface of the latter, to be severed between the sharp ends of grooves 116 and the sharp edges of the needle apertures in the feed dog. The needle threads are simultaneously severed by a device which is the subject of Specification 1, 020, 247.

Abstract: 1,016,710. Compressors. ATLAS COPCO A.B. Sept. 28, 1964 [Oct. 3, 1963], No. 39487/ 64. Heading F1N. In a plant for obtaining dry gas, wherein a compressor 1 supplies gas through a heat exchanger 3, a cooler 4, a mechanical moisture separator 5, a silica-gel moisture adsorber 7, a check valve 8 to a consumer 10 and a main receptacle 11, the adsorber 7 and the separator 5 are periodically purged of moisture by automatically opening an electromagnetic valve 6 to allow compressed gas in an auxiliary receptacle 14 to pass through a pressure reducing restriction 13, the adsorber 7 and the separator 5 to a drain 18. The drain 18 may be connected to atmosphere, a condenser or a vacuum source. The gas in the auxiliary receptacle 14 is supplied by the compressor and is heated electrically, or as shown, by the heat of compression. The opening of the valve 6 is controlled by a switch 12 responsive to the pressure in the main receptacle 11 and also operative to stop the compressor motor 2. In an alternative plant (Fig. 3 not shown) a time controlled valve in a bypass line is opened simultaneously with the valve 6 and allows gas to pass from the main receptacle to replenish the auxiliary receptacle. In another plant a pair of moisture adsorbers each having an associated restriction and auxiliary receptacle are connected in parallel whereby the compressor may run continuously while allowing one or other of the adsorbers to be purged of moisture.

Abstract: 1315883 Cases F N KOLOMEIR 24 Aug 1971 [11 Sept 1970 30 Nov 1970] 39638/71 Heading B8P [Also in Division B6] A marking appliance comprises a casing 3, Fig. 4, carrying a number of marking units 7, 7B, 7C &c., in tandem, each unit having means which when the unit becomes the leading unit co-operates with means on the front end of the casing to locate and maintain that unit in a marking position. Also, preferably means are provided for temporarily connecting the units, so that withdrawal of the leading unit when it is used up, causes all the units to be moved forwardly in the casing, and the second unit to be moved into marking position. As shown, each unit has a reduced part 11 holding a pencil lead 21, but the marking means may be a crayon, a pen with an ink cartridge, a stylus or a cosmetic pencil. The part 11 extends from a body part 9 of larger diameter having a groove 33 formed with a shoulder 35 near its forward end. An integral or separate front part 31 of the casing 3 is formed with spring tongues 37 by slitting, and these tongues engage the groove 33 of the leading unit to hold that unit in writing position and to prevent rearward movement of the unit. The inner surface 23 of the body part 9 recessed to receive the lead 21 has a smaller diameter than the part 11, but the part 9 is slotted at 51 so that the rear end can expand and grip the leading part 11 of a following unit 7B to detachably connect the units. A series of units so connected can be loaded on to the casing through the rear end of the casing if that end is open, or if the rear end is closed, the loading can be effected at the front end if the front part 31 is first removed from the casing. A member (55, Fig. 5) may be insertable in the open rear end of the casing to prevent the units from falling out of the easing.
