Abstract: 302,002. Blakeborough, R. A., and Blakeborough, J. B. Oct. 11, 1927. Strainers having sheet straining-materials.-A flanged cylindrical straining basket b is supported by a web a<3> which separates the inlet a<1> of a casing a from the outlet a<2>. A rotating tube d passes upward through the base of the casing and is bent outwardly and upwardly to form a chamber d<2> adjacent to and open towards the basket b. The upper end of the chamber d' is guided by an annular groove f in the web. A plate d', which closes the bottom of the strainer, and a casing o<1>, to which liquid under pressure is supplied by a pipe p, are formed integral with the part d<2>. As the tube d and the parts cannected thereto are revolved by means of a gear wheel h gearing with a pinion i driven by a motor j, the part of the strainer at any instant between the casing o<1> and the part d<2> is cleansed by a reverse flow of liquid, impurities being carried away through the tube d. The lower end of the tube d may be open to the atmosphere, a flap valve r being provided to prevent the ingress of air. A modification is described in which the pipe p and part o<1> are omitted, the reverse flow being that of strained liquid from within the basket. The port d<2> may have apertures so that jets of liquid are directed at a suitable angle against the basket. The liquid passing down the pipe d may be used to drive a turbine or other motor.

Title: Improvements in automobile alarms
IPC: B60R25/10
Filed: 1919-11-11
Abstract: 160,870. Brock, G. H., and Stoothoff, F. L. Nov. 11, 1919. Theft and like alarms.-Relates to an automobile alarm which draws attention to any unauthorized movement of the car, but does not interfere with the control of the car by an unauthorized person in an emergency. Fig. 1 shows the electrical connections of the appliance in its normal locking position. The brake lever 2: and the gear lever 1 are locked by a pair of forks 3 pivotally mounted to the footboard. The device is then made operative by closing the switch 10, by means of a key, the arms of the switch bridging the four contacts as illustrated. The rear end of the forked levers 3 terminate in an upwardly-extending portion 6, which in the locked position engages with a contact to complete the circuit through the electromagnet 16, the armature 17 being held in its raised position. Subsequent movement of the forks 3 to release the levers 1, 2 results in the breaking of the circuit, the armature 17 ceases to be attracted by the magnet 16, and engages with the contact 18 to complete a circuit through the sounding- device 19. If the lead 9 has been removed to render the device inoperative, upon the engine being cranked sufficiently to cause a generation of current within the magneto 20 to promote ignition, the electromagnet 22 is energized and attracts the armature 23. This engages with the contact 24 and diverts current through the switch 10 to the sounding-device 19. The electromagnets, switch, and sounding-device are enclosed in a casing 25, Fig. 5, which is secured to its supporting-means by screws 26, which also serve as current conductors for the wire 15, and when in place close the contacts 27. Thus if a thief conttives to remove the casing, or by withdrawing the screws 26, cuts the leads 15, the circuit through the electromagnet 16 is broken and the alarm sounded.
