Patent GB-743876-A (GB)
Abstract: 743,876. Fitters. SWALES (FILTERS), Ltd., C. A., and NEWALL ENGINEERING CO., Ltd. July 6, 1954 [July 10, 1953No. 19255/53. Class 46. [Also in Group XXX] A continuously-operating filter of the kind comprising a length of filter material mounted so that it can be fed on to and preferably moved along by a movable trough-like apertured support, e.g. an endless band, the support and filter material thereby forming a trough into which the liquid to be filtered is fed, and level-responsive means in the trough for controlling the rate. of movement of the support so that the filter material is fed forward when it has become so clogged that the liquid in the trough has risen above a predetermined level, ischaracterized by the provision of a series of transverse bridges on the support whereby the filter material is supported thereon in a series of transverse troughs. A roll of filter material 17, Fig. 2, on a roller 18, Figs. 1 and 2, is positioned so that its free end can be drawn upwards and along the upper run of an endless band 9, Figs. 1 and 2, formed of wire mesh links and having a central section of uniform length, and side sections 11, 12, which are longer on their outer sides so as to form a trough-shaped structure. The outer sides are supported on wheels 13, Fig. 1, of sufficiently large diameter to maintain the troughed-shaped form, while transverse elements 14 engage sprockets 15 which at one end of the band are driven by an electric motor (not shown) housed underneath a tank 10 over which the band 9 is located. As the material 17 is fed on to the band 9 an idler roller 21, pivoted by arms 22 and a rod 22a about brackets 23 (and shown in a raised inoperative position in Fig. 1) falls gravitationally between transversely extending bridges 16 (shown more clearly in Fig. 1) provided on the band 9, thereby forming shallow troughs-in the filter material 17. Thus a greater area of filtering material is located above the tank 10 at any one time than would be the case if the transverse troughs were not formed, resulting in quicker filtration. The roller 21 may be spring-loaded or it may be operated by a cam driven by or in synchronism with the band 9. A float 20, Fig. 1, effects switching-on of the motor when the paper becomes clogged and the liquid level has risen in consequence. The roller 18 is driven by the sprocket-carrying shaft through a chain drive in a housing 24, Fig. 1.

Title: Telephone with long distance dialling lock out
IPC: H04M1/677
Filed: 1978-06-05
Abstract: When zero on a telephone is dialled first by an unauthorized person hoping to establish a long distance line, a first blocking-spring actuated by a boss driven from the dial arrests reverse rotation of a lug before it can separate the signalling contacts so that zero is not signalled but another digit is signalled instead. A second blocking-spring is actuated by the boss as it returns to starting position for holding the first spring out of engagement with the lug so that a local number can be dialled. For normal operation of the telephone, a manually operable member is moved into a position in which is prevents the lug-stopping actuation of the first spring. The telephone also can be set to prevent all outgoing calls while permitting incoming calls to be received. <IMAGE>
