Title: Improvements in and relating to apparatus for dispensing liquids in measured quantities
IPC: B67D7/16
Filed: 1921-04-20
Abstract: 183,542. Woodruff, F. April 20, 1921. Fixed-chamber apparatus; varying quantity measured in ; valve systems for.-Relates to apparatus of the kind in which the capacity of a chamber provided with a discharge port and a fixed overflow port is varied through a displacement body, and comprises a construction in which a sliding rod is associated with the displacement body, the rod being set into any required positions, and means exterior to the chamber acting in conjunction with the rod for indicating the position of the body. Liquid, more particularly gasoline, is delivered to the bottom of the measuring-chamber 1 through a pipe 3. The chamber 1, which may have transparent windows in its walls is located at the top of a hollow standard in which is housed the indicating-mechanism. A fixed overflow pipe 4 leading back to the storage chamber extends into the chamber 1. A discharge port 13 controlled by a valve 14 is provided in the bottom of the chamber 1. Surrounding, with clearance. the pipe 4 is an annular displacer or float 5 and passing up through the pipe 4 is a rod 7 carrying at the top a spider and fitted with a movable stop 10 adapted to engage any of a series of fixed notches in a bar 9 graduated to show amounts of liquid. In use, the rod is set to any particular notch, and the liquid under pressure admitted through the pipe 3. The liquid is admitted until it overflows through the pipe 4, the float being arrested by the spider. The chamber 1 contains an amount of liquid between the chamber and the displacer up to the level of the top of the pipe 4, and this corresponds with the amount indicated by the particular notch in which is located the stop on the rod 7. The pump is now stopped, and the vessel discharged through the cock 14. A drain pipe 15 having a valve 16 leads back to the tank through the pipe 4. At night, when the apparatus is not being used, this valve 16 is open, and it must be in the open position before the door 17 of the standard can be closed. In a modification, a chain, attached to the top of the float passes over pulleys at the top of the apparatus to a weight sliding in a tube outside the chamber fitted with observation holes thus forming an indicator. In this form the valve 14 is locked until released by the stop 10 on the rod 7 'engaging a special notch above the others.

Title: Improvements in or relating to coke oven batteries
IPC: C10B29/02
Filed: 1950-05-08
Abstract: 667,547. Coke ovens. OTTO, C. May 8,1950, No. 11458/50. Class 51 (ii). In a coke oven battery of the type which is divided by transverse vertical walls into sections which form alternate relatively narrow coking chambers and heating flues, each heating flue being sub-divided in the longitudinal direction of the battery by vertical flue division walls into vertical flue spaces connected in pairs at their upper ends to form vertical hair-pin flues, the structure of said sections being of superposed courses of silica bricks, the brickwork construction comprises flue division walls J and K formed of binder bricks L defining with liner bricks M and m the flues I, the arrangement being such that one end of each binder brick L extends through the heating wall and is flush with the side of the adjacent coking chamber constituting a tenon l extending into a socket space formed by adjacent liner bricks M and m, the opposite end l<SP>1</SP> projecting into a shallow recess O formed partly in each of the bricks M and m, adjacent superposed bricks L being turned end-for-end with respect to one another. A major portion of each recess O is formed by a corner notch 21 in a brick m with a shorter corner notch 2 in a corresponding brick M, and the abutting ends of each pair of bricks M and m at this point are separated by a vertical expansion joint N, the other end of the brick m being separated from the tenon l by an expansion joint n. With this construction the liner bricks m have a greater frictional association with the particular binder brick K or L associated with the notch 21 and on cooling tend to remain with such binder brick, thus opening the joints N and n in preference to causing fractures in the brickwork. As shown in Fig. 4, the end of each brick M adjoining a brick m has upper and lower sides cut away to form a tapered tenon received in a socket formed by adjacent walls of binder brick tenons l in the courses respectively above and below the brick M and at each end of each flue division wall the expansion joints form a combined zig-zag joint Nn. The end l of each binder brick is formed with a shoulder l<SP>2</SP> overlapping the expansion joint n, whilst the end surface of the other end l<SP>1</SP> overlaps the expansion joint N. The division walls J are shorter than the walls K, thus defining the bends of the hair-pin flues I and a single course of liner bricks M, m above the level of the top of each wall J comprises longer bricks formed without the notches 2 and 21, Fig. 5 (not shown. In a modification, Figs. 6 and 7 (not shown), both binder and liner bricks are formed with interengaging grooves and sockets in their contacting surfaces, the recesses O are dispensed with, and the bricks m are formed with projections against which the ends l<SP>1</SP> of the bricks L abut.

Title: Improved Apparatus for Proportioning the Mixtures of Fluids.
Inventor: COLLINS CHARLES SHELTON
IPC: G05D11/00
Filed: 1919-05-09
Abstract: 130,582. Collins, C. S., and Roessel, L. July 30, 1918, [Convention date]. Mixing fluids in flow.-Relates to the regulation of the proportions of mixtures of fluids, and consists of a method and means for controlling the rate of flow in apparatus which maintains various proportions of the fluids, which may be gases or liquids or both. The pipe 10 conducts one fluid, the pipe 11 another to the pipe 100 connected to a receiver. A valve 15 determines the pressure in the part 10<a>, which communicates with one side of a diaphragm or piston valve 18 of a compensator 16 by a pipe 17, the other side communicating with the pipe 11<a> by a pipe 19. If the pressure in the pipe 10<a> is the greater, the diaphragm 18 moves a piston-rod 21 of a valve 22 to open ports 23 to permit more fluid to pass to the pipe 11<a>, until a definite relationship, depended upon the primary pressure in the pipe 10<a>, is established. The rates of flow through pipes 10<a>, 11<a> are established by orifices 28, 29, the pressures at the outlet sides of which are equal, being the pressure of the receiver. The relative ratio of flow are thus governed by the valve 15. Additional supply pipes such as 12 may also be provided, similarly controlled and connected, and is shown with a heating or refrigerating section 39 in the circuit, the connexion 40 to the diaphragm controller 32 being beyond this. To vary the rates of flow for this, the orifices 28, 29, 35 may be adjustable and may then comprise a casing 70, Fig. 2, containing an orificed bushing 71 controlled by a cone-shaped member 76 hung on brackets 7, 74 in a head 72, and adjustable by rack teeth thereon engaging the pinion end 78 of a shaft 79 disposed in the head 72, and provided with a key 81 in a cap 82 screwed in the head 72 and bearing on a packing-ring 83 in a pocket 84. The Specification also describes apparatus whereby, after the pressures are compensated, several supplies can be taken off the pipes at various points through controller mechanism which replaces adjustable orifices, and provides for control of flow in one pipe from the flow in the other. Specification 27703/10 is referred to.
