R., 103, Newbold Road, both in Rugby. May 6, 1931, No. 13403. [Class 105.] Variations in electrical capacity, such as the capacity of a safe to earth which is varied by the approach of a person are caused, to operate an indicator or alarm by means of a circuit including a three-electrode mercury vapour valve the control electrode circuit of which includes the capacity and is so arranged that no anode current flows until variations in the capacity take place. The Figure shows a mercury vapour triode 1 deriving its filament and anode supply from the secondary of a transformer, to one end 5 of which the grid is connected through a condenser-resistance combination 6, 7. The point 5 is always negative to the filament when the anode is positive and the values of 6, 7 are such that normally no anode current flows. The safe 4 is also connected to the grid and has a capacity to earth represented at 11. Any change in this capacity reduces the effective grid bias and anode current flows, operating an alarm which may be connected in the primary leads 14 of the transformer. A metal plate 11<1> is provided near the safe, and is connected at two points to the supply transformer, one through resistance 13, whereby an alarm is also given if either connection is cut. The invention may be applied to the automatic operation of signalling or speed control means for railway trains.

Filed: 1921-05-17
Abstract: 178,739. Smith, C. A. May 17, 1921. Plates, dishes, and the like, washing.-A positioned dish is automatically lowered into washing-fiuid and its inner surface brushed; it is then raised to its first position and its outer surface brushed; finally it is ejected from the machine. Rotation of a handle 8 secured to a gear-wheel 10 causes the engagement of a roller 9 thereon with a pivoted cam-plate 13, thereby lowering a platform 2 carrying a conveyer 3 which supports the dish 4 to be washed by means of a link 17 against the action of springs 5. On further rotation, the roller disengages from the camplate, but engages with a pivoted lever 19, thereby moving the conveyer laterally by a pin-andslot means. In the lower position, the dish is immersed in the liquid, and its interior is cleansed by a brush 26 rotated from the gearwheel 10 through a pinion 32 and bevel-gearing 30, 33, and also oscillated by the engagement of a pin 34 projecting from the shaft 31 of the pinion 32 with a spring-controlled lever 36 which bears against the brush shaft at its other end. The exterior of the dish is cleansed during its lateral movement by fixed brushes 40, which act to retain it in a displaced position on the return of the conveyer. On the following lowering of the platform, the dish is tilted over the edge 42 of the tank and discharged into a receiving rack 44, which is intermittingly rotated to bring a fresh compartment into receiving position by a ratchet device actuated at each rotation of the handle 8.

Title: Improvements in electrical stop motions or signalling means responsive to breakage or tension of threads and the like in warping or other textile machines
IPC: D02H13/00
Filed: 1939-05-09
Abstract: 528,543. Warping-machines. PHOTOSWITCH, Inc. May 9, 1939, No. 13837. Convention date, July 28, 1938. [Class 142 (iv)] [Also in Group XL] In an electrical stop motion or signalling apparatus responsive to the breakage or tension of one of a number of threads or the like in a warping or other textile machine through the conditioning of a photo-electric element by a light beam effected by the thread, a single beam is so correlated to all the threads that it is obstructed or cleared upon deviation from the normal position of any one of the threads, either by the thread itself, or by a target moved by the deviatory thread, or upon deviation from normal position of a feeler element common to the threads and moved by the deviatory thread. As shown in Fig. 2 targets T, suspended from the threads F, extend into guide slots of a tubular retainer R and a lamp in a housing 15 directs a beam through the tube R to strike a photocell of a photoelectric relay circuit C described in Specification 514,528, [Group XL]. When a thread breaks, the corresponding target T falls and interrupts the beam which actuates a signalling or stopping device. The targets may be omitted, especially if the threads are comparatively thick, and two light beams are arranged so that only breakage or undue tension will cause the threads themselves to interrupt one or other of the beams. In the arrangement shown in Fig. 5 feeler wires W1, W2 are arranged above and below the threads F and are attached to a lever 26 carrying a target 28; any abnormal movement of a thread will cause a rider TI carried thereby to engage a feeler wire and move the lever 26 and admit light to the photocell P. When the .threads run in several planes the light beam is diverted by reflectors through several retainer tubes. Forms of targets are described and the tube R may be replaced by a helical spring or by guide wires arranged parallel to the beam.
