Title: Emergency release mechanism for a rotary ironing machine whereby the rotary roll is moved away from the ironing shoe
Inventor: SCHRADER LOREN E
IPC: F16D11/00
Filed: 1958-09-08
Abstract: 841,458. Release mechanism for ironing machines. IRONRITE Inc. Sept. 8, 1958, No. 28796/58. Class 138 (2). An emergency release mechanism for an ironing machine of the type in which a tubular shaft supports a roll for movement towards and away from a fixed shoe, comprises a body coaxially mounted within the shaft and connected thereto by a locking means comprising a pin extending radially of the body and movable axially of the body to engage an annular spool which is connected to and is mounted within the shaft between the shaft and the body, the rotation of an actuator lever in the same direction as that of the roll away from the shoe rotating a ring member about the body so that in one position it holds the pin in engagement with the spool and in the other position it allows the pin to move out of engagement with the spool. As shown, Fig. 3, the tension of spring 31 created by the rotation of cam 28 is applied to roll 22 via body 33, which has a slot in which is diametrical pin 51, notch 39, spool 36, tube 17 and thence via arms 18 to the roll. The safety device is released by rotating arm 63 which rotates trigger ring 53, bringing notch 57 into line with notch 39 so that pin 51 moves into the former and releases the positive connection between spring 31 and the roll 22. To reset the device, arm 63 is rotated towards shoe 13 and when it makes contact with the extremity of its slot 62 in tube 17 it rotates tube 17, spool 36 and its notch 39 until the notch comes opposite pin 51. The pin is then driven into the notch by spring 19 and, notch 57 being freed of pin 51, trigger ring 53 returns to the position shown in Fig. 3 under the action of spring 72. Specification 837,755 is referred to.

Filed: 1926-11-15
Abstract: 262,088. Lasmolles, J. R. F. M. Nov. 27, 1925, [Convention date]. Producers. - A Wood-consuming gas-producer has superposed fuel beds f, f<1> separated by a grate g which allows charcoal to fall into the lower fuel bed which reduces the tarry products and transforms the carbonic acid and water vapour from the combustion in the upper fuel bed into carbon monoxide, the reaction taking place on a pile of refratcory balls r. The air for combustion is preheated in a bell c and enters through openings controllable at a. Automatic air intakes d carrying balls displaceable from the openings to the air, admit air when a sudden demand is made by the engine using the gas. The producer gas passes through a dust filter n filled with iron shavings and then through a series of boxes m connected by pipes in which condensation takes place.

Title: Engine brake horsepower test without external load
IPC: G01L3/24
Filed: 1975-07-09
Abstract: 1509785 Testing internal combustion engines RCA CORPORATION 9 July 1975 [21 Oct 1974] 28882/75 Heading G1N An internal combustion engine is tested by running the engine at a equilibrium speed determined by the friction torque with all but one of n ignitions inhibited, decelerating the engine without any ignition, and measuring the rate of deceleration of the engine in the region of the equilibrium speed whereby the brake torque of the engine may be determined as by a computer by multiplying the aforesaid rate of deceleration by the known ratio of the engine and by n-1. As disclosed when the engine is running at the equilibrium speed all ignitions are enabled such that the engine builds up speed until the number of revolutions is of the order of 500 r.p.m. above the equilibrium speed. Thereafter the engine is decelerated as stated above and the deceleration is established as the engine deceleration through the equilibrium speed. The speed of the engine falls to 500 r.p.m. below the equilibrium speed. The speed of the engine is determined by timing the separation of the ignition pulses as by counting clock pulses from a 100 KHz clock.

A variable such as the flow of a fluid produces an analogue signal which is converted to a train of pulses of corresponding frequency. the latter being counted over a predetermined fixed period, e.g. 10 minutes. At the end of this period, the counter is reset and its contents are transferred to a first store. At the end of a second 10 minute period, the contents of the counter are transferred to a second store, and so on for successive 10 minute periods. There are as many stores as there are 10 minute periods in an interval over which the total flow of fluid is required to be measured, e.g. for an interval of 4 hours there will be 24 stores. Each store controls current generators connected to a resistor network giving an output analogue signal which represents the total flow of fluid over the 4 hour interval. By transferring the contents of the counter to the first store at the end of the 25th period, and continuing the storage sequence, the resistor network provides a signal representing the total flow over the 4 preceding hours. The counter comprises two sections, the least significant stages not being reset nor having their contents transferred to a store at the end of each counting period.
