Title: Apparatus for heat treatment of liquids
IPC: A23C3/037
Filed: 1963-12-04
Abstract: In the heat-treatment of a liquid, such as the sterilization of milk, by first indirectly preheating it, thereafter heating it to a pre-determined temperature by direct mixing with steam and finally cooling the heattreated liquid to a temperature which is innocuous for the liquid by a rapid pressure drop under evaporation in an exhausted expansion vessel, the liquid is indirectly pre-heated to a constant temperature and the difference between the temperature of the liquid prior to direct mixing with steam and after the pressure drop during evaporation is kept at a pre-determined value by controlling the pressure (vacuum) at which the evaporation occurs, such that the quantity of water withdrawn from the liquid by the evaporation due to the pressure drop is identical with that supplied by the steam as condensate. The liquid may be diverted to a return system as described in Specification 967,125 should the predetermined temperature be not reached.

Title: Apparatus for dispensing measured quantities of liquids
IPC: B67D1/12
Filed: 1965-04-26
Abstract: An apparatus for dispensing a measured quantity of gaseous liquid, such as beer, comprises a liquid measuring vessel 30 connected to inlet and outlet valves A, C and a gas expansion chamber 32 having a valve 42 for admitting liquid therein and communicating with the vessel via ports 52, 53, the arrangement being such that when the liquid has filled the vessel and has reached a level in the chamber determined by the balance of the liquid and gas pressures, the supply of liquid to the vessel and chamber is cut off and the discharge valve is opened whereupon the gas under pressure passes by way of the ports 52, 53 to effect discharge of a measured quantity of the liquid from the measuring vessel through the outlet valve C. The inlet and outlet valves A, C and the valve 42 are actuated by means of cams 24, 25, 48 mounted on a shaft 20 which is rotated via a handle 81 the inlet and outlet valves each have a resilient washer 12, Fig. 3 (not shown), and the cams act on the ends of the valves via a cup 14. The valve 42 is provided with an extension 49 slidable in a guide 51 having bores 53, 70, the bore 53 being normally closed by a spring-loaded needle valve 60, Fig. 5 (not shown). The valve 60 is opened by a diaphragm 62. In operation, with the inlet valve A and valve 42 open as shown in Fig. 1, beer under pressure is fed into the vessel 30 and rises into the expansion chamber 32 until the gas pressure therein balances the pressure of the beer. The cam-shaft is then rotated to close the inlet valve and valve 42 and open the outlet valve C. The pressurized gas in the expansion chamber 32 then flows through port 70, past the needle valve 60 and then through port 52 to thereby assist in the dispensing of the beer from the measuring chamber a pair of identical measuring chambers and associated valves are mounted side by side so that as one chamber is filling the other is dispensing. Additional pressurized gas may be fed via a manifold located in the base 1 of the apparatus in order to accelerate the dispensing operation.

Title: Improvements in or relating to automatic telecommunications exchange systems
IPC: H04Q3/42
Filed: 1969-11-18
Abstract: In a program controlled exchange system markers are functionally specialized in the control they exercise over the same network, one marker of a pair pursuing a co-called pre-test function while the other selects paths and switches them through, either marker being able to take over the duties of the other in the event of a fault. The function pursued by a marker is determined in accordance with a data store which programs its actions. The markers of a pair can operate concurrently in the service of different connections. Each marker is brought into service by applications received over individual demand wires from controlling circuits, the marker scanning the wires to serve demands one-at-a-time. The functions pursued by a marker pair may be exchanged from time-totime or they may be switched in response to date received over a data bus common to the system.

Title: Process for the elaboration of chrome steels
IPC: C21C7/068
Filed: 1974-01-16
Abstract: Chrome steels, particularly stainless steels, are made by blowing an oxidising gas into an electric furnace containing a bath of molten metal containing chromium to decarburise the metal, the oxidising gas being blown in below the surface of the metal and passing through the bath from the bottom upwards. The or each jet of oxidising gas is peripherally surrounded at its point of entry into the metal by a fluid refractory-protectant such as fuel oil. The metal bath initially contains more than 0.7% carbon, and can contain more than 1.2% carbon. The absence of any upper limit on the initial carbon content allows the use of carburised ferro-alloys, and the refining of relatively high carbon content baths.
