Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T8/18
Filed: 1925-12-10
Abstract: 267,224. Winter, H. J., Simmons, A. W., and Westinghouse Brake &. Saxby Signal Co., Ltd. Dec. 10" 1925. Fluid-pressure.-In order that a reduced braking pressure may be obtained on an empty or lightly loaded vehicle as compared with that on a loaded vehicle, a valve is provided adapted to cut off the supply of air to the brake cylinder when the pressure therein is a predetermined amount less than that in the auxiliary reservoir, the valve being by-passed under loaded conditions. The effective capacity of the brake cylinder may also be increased in unloaded conditions so that a relatively lower braking pressure is obtained with a given fall in train-pipe pressure. The triple valve 3 is provided with a valve 8 controlled by a piston 11 subject on its under side to the pressure in the auxiliary reservoir 1 by way of the passage 22 whereby normally the valve is held open against the pressure of a spring 13. A cock 6 is provided which in the position shown connects a passage 5 to the valve 8 by the passage 7 and also connects a chamber 23 to the brake cylinder 2 by a passage 24. Thus when the triple valve moves to application position air from the reservoir 1 is supplied to the brake cylinder and to the chamber 23 by the passages 5, 7 past the valve 8 and passage 9. When the brake cylinder pressure acting on the upper and larger area of the piston 11, together with the spring 13 is sufficient to overcome the auxiliary reservoir pressure acting below the piston, the valve 8 closes. In order to restrict the flow of air to the brake cylinder when a predetermined pressure has been reached therein, there may also be provided a valve 25 controlling an additional passage to the brake cylinder, and adapted to close when the brake cylinder pressure acting on a piston 28 overcomes a spring 22. For a loaded vehicle the cock 6 is turned to the position in which the passage 24 therein connects the passages 5, 9<1> thus cutting out the valve 8 and the chamber 23 which in this position of the cock is connected to atmosphere. The relative capacity of the passages 7. 24 in the cock 6 may be such that either the rate of filling of the brake cylinder or the time interval required to obtain the final pressure therein may be the same under light and load conditions.

Abstract: 463,279. Locks. PARKES & SONS, Ltd., J., FRYER, E. C., and BUTTER, F. J. Nov. 14, 1935, No. 31481. [Class 44] A latch bolt is retained in its inward or outward position by a tongue 42 on it being engaged by a rocker 37 mounted on the inner surface of the cap plate and having a handle 40 extending through a slot 41 in the case plate. The bolt is also held in its locked position by a lever which can only be removed from its obstructive position by the key operated follower which then continues its movement to withdraw the latch-bolt. The head 12 of the latch bolt is secured to the flange 13 of the lath 11 which has upturned lugs 14, 15 at its rear end, the latter lug 15 being shallow compared with the former, 14. A metal strip 20 carries a coil spring 19 which tends to move the lath 11 forward, and the handle carries a follower 16 with horns 17, 18 to engage the lugs 14, 15 respectively. The key follower 24 has two horns 26, 27 ; the former 26 engages the lug 14 when the key is turned to draw back the bolt, while the latter 27, when the key is turned the reverse way, engages a projection 29 on a pivoted lever 30. This moves the end 32 of the lever to engage the lug 33 on the lath so that the bolt is dead-locked, and cannot be moved back by the handle. When the key is inserted and rotated, the lug 27 of the key follower leaves the projection 29 and restores the lever 30 to its former position ; further rotation of the key withdraws the latch-bolt. A metal strip 51 is caused by a spring 52 to engage in a notch 55 in the lever 30 so that the lever only rests in one of its extreme positions.

Title: Method of making low density epoxy resin composition
IPC: C08J9/32
Filed: 1961-09-04
Abstract: A liquid epoxy resin is mixed with micro-balloons and a slow acting resin activator, the mixture is formed into a thin layer which is vibrated to cause air bubbles to rise to the surface where they are broken by an impinging blast of hot air, and the bubble-free mixture is then cast and cured.  Suitable activators usually have two or more reaction group, e.g. OH, NH2 or COOH groups. Suitable ones are sold under trade names as Activator "D" (a tert. amine salt) and Activator "Z" (a mixture of m-phenylene diamine with other aromatic amines). Preferably the resin is heated before mixing with the micro balloons to reduce its viscosity. In an example, Epon 828 was heated to 170 DEG F., and mixed with 25% of BJO-0930 micro-balloons. Activator "D" was then added. The mixture was poured into trays to a depth of 1/2 inch, vibrated for 30 minutes at 60 cycles/second and a blast of air at 400-500 DEG F. is directed at the surface.  The bubble-free material was cooled to 115 DEG F. and cast in a mould and cured at 90-100 DEG F. for 12 hours followed by post cure for 1 hour at 160 DEG F. and for 2 hours at 200 DEG F.  The product is used in manufacture of rocket motors.

In a method of coking coal in a horizontal coke oven, the temperature profiile of a heating wall or walls is repeatedly determined during the coking period and compared at each stage with a predetermined model, the heating of said wall or walls being adjusted to cause the measured profile to conform with the model. The heating adjustments may be repeated in subsequent coking periods by a programming device. Alternatively, a set of model temperature profiles is stored in a memory to be compared with measured profiles in one or more ovens appropriate to the stage of coking reached, the deviation for an oven being used to adjust the heating system in a sense required to nullify the deviation. A group of ovens may have the heating regulated in accordance with a measured profile for one oven in the group. Control may conveniently be accomplished by control of the proportions of inert gas, air or recycled waste gases in a mixture constituting the fuel gas.
