Patent GB-1187381-A (GB)
Title: Operations Controller
Inventor: COLLINGE HARRY
IPC: G05B19/14
Filed: 1966-01-18
Abstract: 1,187,381. Programmed electric control. IMPERIAL CHEMICAL INDUSTRIES Ltd. April 18, 1967 [Jan.18, 1966], No.2263/66. Heading G3N. A programme for a machine or chemical plant is set up on programme cards which are patched through AND gates A mounted on the cards to control solenoid drive circuits SD for hydraulic valves controlling the machine or plant. The gates are enabled by a selector and satisfied by signals from a timer, having a programmed delay, or by plant input signals from the plant or machine being controlled. When satisfied, a signal is fed from the AND-gate A to a reset 1 circuit which emits a pulse to step on the selector thereby enabling the next AND-gate and resetting the timer. The reset circuit 1 comprises a filter, whereby interference is ignored, which triggers a first monostable circuit producing the selector stepping pulse and triggers a second monostable circuit which inhibits the first monostable circuit so that when the selector enables an AND gate that is already satisfied the selector is again stepped. Each solenoid drive circuit SD can be programmed to be operated on a number of selector steps and the state of the machine or plant can be indicated by lamps, not shown. A reset 2 circuit is used to step the selector to the initial position after a programmed number of steps, on the occurrence of a fault, and at the start of a programme. Manual stepping of the programme is effected by a single shot signal into the reset 1 circuit. The circuit shown by the broken lines permits programmed jumps between any steps of the selector by AND gates which are enabled from the programme card. The jump control circuit is similar to the reset circuit 1 and through a solenoid drive circuit SD, operating as a power amplifier, which, via the selector inhibits the programmed jump AND gates A so that the information in a jump memory cannot be changed until the jump is completed. It is stated that a jump to steps other than zero can be arranged by providing additional reset circuits 2.

Filed: 1925-02-04
Abstract: 228,907. British Thomson-Houston Co., Ltd., (Assignees of Pipkin. M.). Feb. 4, 1924, [Convention date]. Ornamenting.-In producing a frosted surface on the inside of electric lamp bulbs or similar hollow thin glass articles, the surface is treated chemically or mechanically in the usual way, after which it is treated with an agent having a solvent action on the glass, the object being to provide a strengthened bulb. As solvent agent, a solution of ammonium bi-fluoride is preferably employed, solutions of potassium bifluoride and sodium bi-fluoride being also suitable. The bulb is cleaned with a dilute solution of ammonium-bi-fluoride, is washed, is then filled with a frosting medium which is allowed to remain from three to seven minutes and, after being again washed, is treated for five minutes with a solution of ammonium bi-fluoride, preferably warmed to 80‹ C. In an alternative process, particularly suitable for small bulbs, the small amount of frosting medium remaining in the bulb after it is emptied is utilized, the bulb being simply filled with warm water and agitated. The frosting medium employed is prepared by grinding a mixture of ammonium bi-fluoride, sodium bi-sulphate, and water, adding " foundry flour," and continuing the grinding.

Title: Improvements in or relating to tubular heat exchangers
IPC: C01B3/38
Filed: 1954-02-03
Abstract: 758,030. Tubular heat exchangers; heat insulation. ESSO RESEARCH & ENGINEERING CO., [formerly STANDARD OIL DEVELOPMENT CO.]. Feb. 3, 1954 [Feb. 20, 1953], No. 3259/54. Classes 64(2) and 64(3). In a tubular heat exchanger comprising a bundle of parallel tubes extending between tube plates 3, 4 and surrounded by a shell 1, the external fluid passing through the shell and over the tubes is withdrawn from the shell by way of a space between the shell wall and a baffle 10 disposed within the shell thereby maintaining the shell at substantially the same temperature as the tubes so that thermal stresses are minimised. Fig. 1 shows one arrangement in which the space between the baffle and the shell wall is annular and is closed at one end by a flange 11. Baffles 17 and spiral baffles or perforated grids or discs 18 are provided to promote heat exchange. The external fluid outlet 8 from the annular space is located at the same end of the shell as is the external fluid inlet 7 to the shell. In order that the tube assembly may be withdrawn, the tube plate 4 is small enough to pass through the baffle 10 which is fixed to the shell wall. Alternatively the baffle may extend to the tube plate 4 in which case the inlet pipe 7 extends through the annular space to the space within the baffle 10. The casing may be heat insulated by a layer of calcium silicate or mineral wool and the baffle 10 may likewise have a layer of thermal insulation on its inner surface. The tubes and tube plates may be made from a steel alloy containing chromium and molybdenum and the inlet header 5 may have a thin chromium liner. The apparatus is said to be of use particularly when the heat exchanging fluids are at high temperatures and pressures such as in a fluid hydroforming reactor.
