Title: Improvements in braking mechanism
IPC: B66D5/00
Filed: 1927-10-06
Abstract: 302,436. Helps, A. O. Oct. 6, 1927. Actuated or applied by weights; force-transmitting mechanism.-Brake mechanism particularly for cranes and other lifting machinery comprises two brakes with a time lag or delay action between them so that one brake only is in operation at one time but such that in the event of failure of such brake the second brake will automatically come into operation. Means may be provided whereby the emergency brake may function for normal braking when the normal brake is required to be out of action. According to one arrangement, Figs. 12-14, a pair of shoe or post brakes disposed side by side, of which one a is shown, are applied by weighted levers a<2>, b<2>, one of which a<2> is secured to the shaft c while the other b<2> is freely mounted thereon. The brakes are controlled by a solenoid e connected to the lever a<2>. The shaft c has an arm k keyed thereon provided with a slot through which passes a pin l on the lever b<2>. A bent lever n pivoted to a fixed bracket normally has one arm engaging a pivoted arm n<2> so as to support the lever b<2>. The arrangement is such that if by reason of breakage of a pin or other connection in the brake a. the lever a<2> falls below the normal position for applying this brake, this lever disengages the lever n from the arm n<2> and permits the lever b<2> to apply the emergency brake. To enable the emergency brake to function for normal braking, when the normal brake is required to be out of action for repair &c., a collar of a size accurately to fit the slot in the arm k is placed therein on the pin l so as to prevent the lost motion normally allowed between these parts. This collar m may normally conveniently be carried on the end of the pin l. A lever o is provided for connection to a pedal by which the brake may be released. In another construction, Fig. 3, a pair of band brakes of which one b is shown have one end b<1> of each brake band fixed while the other ends are connected to arms b<2> on a shaft c to which is secured the weighted operating lever. The connection of the end of the band for normal operation to its lever is a simple pin connection but that of the emergency band is a pin-and-slot connection d, d<1> so that this band is applied only in the event of breakage of the normal band. A second hole is provided in the lever b<2> for the connection of the end of the emergency band when this is required to function as the normal brake without lost motion.

To enable a particle measuring system of the Coulter type to be used for continuous flow measurements without noise pick up by means of the long lengths of conducting liquid in the input and output conduits, the flow is broken just before and just after the measuring apparatus to isolate electrically the measuring apparatus. As shown the particle suspension is arranged to drip into the container 62 which it leaves by a metal waste pipe 76 which forms one electrode of the measuring apparatus. The waste flow is also caused to drip in chamber 87. The apparatus is otherwise conventional including an aperture tube 18 having an electrode 20 and aperture 32 through which the particles of the sample are sucked thus changing the impedance of the measuring circuit. The block 56 may be lowered for removal of the container 62 and the aperture 32 can be examined by means of microscope 46 and light source 44.

Abstract: 1,076,441. Photo-electric pyrometers. H. INABA AND I. NAKAKUBO. July 2, 1964 [July 2, 1963], No. 27348/64. Heading G1A. Apparatus for measuring the temperature of a body comprises a photo detector receiving radiation from the body and a reference radiator to generate first and second signals respectively, means responsive to the difference between the first and second signals to indicate the temperature of the body and means responsive to the second signal to adjust the sensitivity of the photo detector. Light from the body 10 and the reference lamp 42 are chopped out of phase and fall on a photo-electric detector 32. A square aperture 34 is located near the lens 28 so that the measurement becomes independent of the distance from the body 10 to the lens 28. The detector output is fed to a circuit 64 which separates the signals S 1 , S2 due to the light from body 10 and lamp 42. The difference between S 1  and S 2 , which corresponds to the deviation of the temperature of body 10 from that of lamp 42 is indicated on a meter 68. The temperature of lamp 42 may be set manually by a potentiometer 46 and the set value is shown on a meter 50. The signal S 2  corresponding to the reference lamp is fed back to a circuit 72 which controls the sensitivity of the detector 32 to keep S 2  substantially constant. The pyrometer may be applied to the control of heat treating of machine parts, in which case a filter 30 is inserted to limit the radiation used to that of wavelength greater than 6000A. Typically the speed with which a flame ring moves along a machine roll being hardened may be controlled by the output of the pyrometer.
