Title: Improved means for driving and adjusting chains carrying the rakes of sewage-screening apparatus
IPC: E02B8/02
Filed: 1931-12-05
Abstract: 392,637. Strainers. HARTLEY, E., 3, Dartmouth Avenue, Newcastle-under- Lyme. Dec. 5, 1931, No. 33736. [Class 46.] The tension of the endless chains 8 carrying the rakes 9 for clearing the screens 20 in sewage-screening apparatus is adjusted by means of sprockets 16 adjustably mounted on the side of the apparatus opposite to that on which the rakes ascend and deliver the refuse. The position of the sprockets 16 may be adjusted for example by tension bolts and lock-nuts 17 or by racks and pawls. The chains pass over the sprockets 16, free sprockets 18, 19, 11 and sprockets 10 secured to a shaft 7. The shaft 7 is driven through gear wheels 6, 4 from a driven shaft 5, which also carries brushes 12 for cleaning the rake. During the travel of the rakes between the sprockets 11, 10 the refuse is deposited in a shoot 13 leading to a receptacle 14 and the rakes are then cleaned by the rotating brushes 12; a guard 15 may be provided to ensure that the sweepings fall into the shoot 13.

[Class 35.] In a multiple layer distributed winding a portion of at least one layer of the winding which produces a magnetomotive force opposing that produced by an adjacent layer is . short-circuited. In the form shown in Fig. 5, the winding is divided into three circuits A, B, C, with coil sides for each circuit distributed among four slots for each pole-pitch of twelve slots. The coil sides in slots 16, 17, 18 and, in addition, the corresponding sides for the other poles would carry currents in opposite directions and therefore a coil side in each of slots 16 and 18, and, with this particular pitch, both coil sides in slot 17, are short - circuited. These short-circuited coils c, h, for each pole are the first coils in circuits A and the last in circuit C, and the circuits A, B, C for each pole are arranged as in Fig. 6 in the case of a single phase machine, the circuits B being parallelconnected to ensure uniform current distribution. The connection m. Fig. 5, provides a neutral point for this arrangement, and the positive and negative signs indicate the connections to the exciter. In an alternative form, circuits A, B, C are series-connected and a similar coil short-circuiting arrangement may be used or, alternatively, only the first coil in each A circuit for each pole may be shortcircuited.

Abstract: 925,762. Plutonium compounds; neutron sources. UNITED STATES ATOMIC ENERGY COMMISSION. Sept. 27, 1961 [Oct. 17, 1960], No. 34576/61. Drawings to Specification. Class 39 (4). A neutron source is made by reacting beryllium and plutonium, the beryllium being in the form of a crucible which contains the plutonium, has an isolating layer of beryllium oxide and/or beryllium nitride on its outer surface, and is disposed in a metal container. The container is at least partially evacuated and sealed, after the crucible is enclosed, and before the reaction between the plutonium and beryllium is initiated. The layer on the crucible may be produced either by heating the crucible in air and then in nitrogen, this latter heating being conducted at a pressure of 15 p.s.i. for about 15 minutes, or the layer may be formed just by heating in air for about 15 mins., or simply heating in nitrogen. After this heating, the inner surface of the crucible is cleaned to present a fresh surface of beryllium to react with the plutonium. Pieces of plutonium are placed in the crucible and the crucible placed in a metal, usually tantalum, but may be molybdenum or tungsten, container which is evacuated and sealed. It is then heated to 1150‹ C. when the plutonium reacts with the beryllium to give PuBe 13  and the resulting body, usually jacketed in stainless steel, is used as a neutron source.

Title: Improvements in the springing of vehicles by means of laminated springs
IPC: B60G11/04
Filed: 1922-12-20
Abstract: 194,643. Stott, J. H. Dec. 20, 1922. Springs, arrangement of.-A full cantilever vehicle spring is arranged to give easy springing during the earlier portion of its deflexion when working alone, and stiffer springing during the later portion of the deflexion and, if desired, of the rebound when working in conjunction with a stop or stops controlling the rotation of its encastrement so as to change the springing at a predetermined point or points from the full cantilever to the quarter-elliptic type. The encastrement of the spring is pivoted at E, Fig. 1, to the chassis H in the usual manner, but at a predetermined point in the deflexion, the arm A, B of the spring is put out of action by stops F, G which prevent subsequent rotation of the encastrement. As shown, the same set of stops may operate during deflexion and rebound, but separate stops may be provided, and a single stop may be used in place of the stops F, G. The stops may be made adjustable by screw, eccentric, or other devices. A pair of cantilever springs, one or both stopped as described above, may be arranged as shown in Fig. 17 to replace a semi-elliptic spring by mounting the encastrement and one end A of each spring on a bracket K secured to the axle, the other end of each spring being connected to the chassis. The springs may be arranged to overlap so that the pivots E coincide as shown, or, to enable a shorter bracket K to be used, only the portions A, B of the springs overlap each other. The arrangement of the springs may be reversed so that 'the points C are attached to the bracket K, the points A, E being carried by the chassis. In the modified suspension shown in Fig. 32, the stops F, G are used to bring into action a pivoted or quarter-elliptic auxiliary spring during the later portion of the deflexon and, if desired, of the rebound of a main suspension spring. Specifications 141,436 and 188,428 are referred to.

Title: Looper thread controlling mechanism for sewing machines
IPC: D05B63/00
Filed: 1921-12-24
Abstract: 188,252. Fairweather, W., (Singer Manufacturing Co.). Dec. 24, 1921. Multiple-needle machines; chain stitching.- Loop-stitch sewing-machines are provided with a thread-nipper and pull off which are so actuated that the pull-off draws back through the nipper any surplus of looper thread remaining after the stitch has been drawn to ensure that each stitch is commenced with the thread in the same condition. The arrangement is described in its application, to a four-needle, single-looper machine of known type, and comprises a pull-off cam 47, nipper-operating cam 49 and take-up cam 48 mounted on a shaft 42. In a cycle beginning with the needles up and the looper forward, the nipper is closed by a hump 60 on its cam and as the looper recedes the slack of its thread is taken up by the take-up cam. The pull-off begins to draw thread from the supply before the looper reaches the end of its receding movement, the take-up at the same time giving up thread to the loop. When the needles are down and the looper withdrawn the nipper is opened for a short time to allow the pull-off, which is then operating at its greatest effectiveness, to draw back any surplus thread through the nipper. The nipper is then closed and the pull-off continues to operate to withdraw thread sufficient for the longest stitch the machine can produce. The timing of the various parts is shown by the diagram, Fig. 4. It is not essential for the nipper to be closed at the point 210‹ after the pull-off has drawn back the surplus thread.
