Abstract: 141,767. Rendell, A. W. Nov. 21, 1918. Fluid-pressure.-Valve mechanism adapted to effect the exhaust of the brake cylinder in releasing the brakes, by an amount dependent upon the increase in train-pipe pressure, comprises a pair of abutments subject respectively to the train-pipe and brake-cylinder pressures and to a spring resistance, and connected by a floating lever or equivalent which actuates a valve controlling the brake cylinder exhaust passage of the triple valve. In the form described, the triple-valve exhaust passage is connected at 5 and the train-pipe at 12. The abutments 11, 16 are connected by a floating lever 8 to which is connected at 7 the valve 1 controlling an exhaust port 2. Under running conditions, the train-pipe pressuro and the spring 17 respectively hold the abutments 11 16, in the extreme positions show and the brake cylinder is open to exhaust through the triple valve and the port 2. When the trainpipe pressure is reduced in applying the brakes, the abutment moves to the left and closes the port 2. Upon the increase of train-pipe pressure after an application, the abutment 11 is moved towards the right hand, and the triple valve connects the brake cylinder to the chamber 16<1> of the abutment 16, which also moves to the right, and the valve 1 is thus opened. When the brake. cylinder pressure has fallen by the necessary amount, the spring 17 moves the abutment 16 towards the left hand and closes the valve 1.

Abstract: 774,349. Thermal switches; snap action switches. GENERAL ELECTRIC CO. July 1, 1955 [July 1, 1954], No. 19159/55. Class 38(5)  A refrigerator control device in which defrosting is initiated manually and terminated automatically comprises first contacts 2, 5 operated by lever 10 and rod 21 in response to a temperature sensitive bellows 18 to'control a compressor motor 7, and second contacts 35. 35 also in the motor circuit actuated by a manually operated member 54 to open this circuit and initiate defrosting. The contact operating lever 10 is biased upwards to the "contacts-closed" position by a spring 16 and engaged by the end 23 of rod 21 which is connected to the bellows 18 and biased downwards by spring 30. Lever 10 has two positions one at lower temperature when the contacts 2, 5 open and one at a first higher temperature when they close. The first higher temperature is determined by the degree of compression of spring 30 which is adjusted by knob 29 rotating a cam 28 to move a spring supporting plate 25. The contact 36 is carried by a spring blade 37 which forms a snap action toggle mechanism with the spring blade 49 and lever 46 which is pivotally connected to the housing by a leaf spring 48, the lever 46 being provided'with a screw 51. Depression of member 54 tilts the screw causing contacts 35, 36 to open, thus de-energizing the motor and at the same time a third set of contacts 36, 34 are closed to energize a'defrosting heater 42. As the temperature rises the operating rod 21 moves upwards from the position shown in Fig. 3, first closing the contacts 2, 5 at the first higher temperature and then at a second higher temperature the end 23 engages the screw 51 actuating the toggle mechanism thereby opening the heater circuit and closing the motor circuit. The second higher temperature is adjusted by the positioning of the screw 51.

Abstract: 748,186. Clocks. JUNGHANS, H., and JUNGHANS, AKT.-GES., GEB. July 10, 1953 [July 11, 1952; July 11, 1952] No. 19206/53. Class 139 In an alarm clock the hammer blows increase in frequency and strength as the alarm mechanism runs down. The hammer rod 5, Fig. 1, is bent at right-angles at 16a, 16 to enter the recess 14c between two arms 14b<SP>1</SP>, 14b<SP>2</SP> of the control lever 14 which has a recess 14a by which it is mounted on the alarm spring arbor 1. The lever 14 has a finger 14e which co-operates as decribed later with a ratchet wheel 11 on the escape wheel shaft 9. A spring 15 urges the lever 14 downwardly. A cam 17 is frictionally mounted on the shaft 1 and is normally positioned so that a right-angled projection 17c abuts the edge of a frame plate and has a cam surface 17a and projections 17e, 17g. In operation when the alarm anchor-arbor 2 is freed the alarm escape wheel 4 oscillates the anchor 3 and the rod 5 the. arm 16a, 16 of which oscillates. the lever 14. The lever 14 is momentarily locked during each swing by the engagement of the finger 14e with a tooth of the ratchet 11 so that the rate of striking of the hammer 6 is slow. At the same time the movement of the hammer 6 towards the bell 7 is blocked by the projection 17e of the cam 17. As the alarm spring runs down the cam 17 rotates and the projection 17e is moved from the arm 16 so that the hammer 6 is allowed its full stroke. Upon continued movement of the cam 17 the cam surface 17a abuts a pin 18 on the lever 14 which is thereby moved longitudinally so that the finger 14e leaves the ratchet to increase the rate of oscillation of the hammer 6. If the clock is of the type in which the hammer 105, Fig. 4, strikes a pin 107 carried by a frame plate the hammer is cranked at 105a and cooperates with the projection 17g of the cam 17 for initially limiting the hammer stroke. Alarm stopping. Upon depression of a push button stem 52 a lever 50 rocks a lever 51 which effects a slight backwards movement of the escape wheel 4 and the parts 50, 51 are retained interlocked by the force of the alarm spring.

[Also in Group XL (c)] D.C. at output terminal 1 is derived by way of a rectifying voltage multiplier 10 from winding 2 of a relaxation oscillator circuit comprising a valve 1, the grid voltage of which increases as condensers C1, C2 are charged through resistance R, so that the valve passes a steadily increasing current to induce a steady voltage in a winding 4 coupled to winding 2. When this is exceeded by the voltage across condensers C1, C2 these discharge through diode 8, the grid volts become negative and the cycle recommences. So that the output voltage does not vary with load, the negative voltage peak induced in winding 7 charges condenser 9 through diode 8 and the voltage across the condenser 9 is applied to the grid of valve 1 through a resistance R1, a biassing voltage being supplied through resistance R3. A resistance R2 is connected in parallel with condenser C2. A relationship between the values of C1, C2, R1, R2 and R3 necessary to give stable voltage is set down.
