Title: Improvements in and connected with hot water and like installations particularly such as are employed for heating systems in buildings
IPC: F22B1/26
Filed: 1928-01-06
Abstract: 309,222. Hammond, C. F., and Shackleton, W. Jan. 6, 1928. By aerating ascending column.-A heating system for buildings comprises an air-lift apparatus receiving combustion gases from a submersible burner, connected to the head of the cold liquid return column of the circulating system so as to heat and raise liquid to a tank at the head of the hot descending column. The combined heating and air-lift apparatus illustrated may be situated at the top of a building and connected with the radiators by a descending hot water pipe a and rising, cold water pipe b. The submersible burner h projects into the foot of the air lift tube f, which projects downwards into a chamber d. The tube f passes through a heat interchange chamber l to a separator m having an annular deflector r. An annular space t is formed in the cover q, which also projects downwards into the chamber m to form a water seal. A delivery pipe w opens into a tank x at the top of the descending hot water pipe a, and the rising cold water pipe b opens into the top of the chamber l. The water level in the chamber l is controlled by a float valve in a chamber z. The fuel and air supplied to the burner may be controlled by a thermostat subject to the temperature of water in the pipe b, or the chamber m, or the tank x. In operation, the aerated water in the column f overflows into the chamber in where gases are separated and pass into the space t. The hot water overflows into the tank x and passes down through pipe a, displacing cold water up the pipe b and into the chamber l, where it passes over the baffles p and meets the hot gases which have passed downwards from space t through passage 8 to the underside of the series of baffles. The cooled gases finally escape through opening 9. In a modification, the separating chamber m, heat interchanger l, and air lift tube are all separated, and connected by pipes. In another modification, the water directly heated by the submerged combustion burner does not pass into the heating system, but is isolated in a separate chamber. The combustion products are thus purified, and are then supplied to a separate air-lift pipe. Specification 265,254 is referred to.

Abstract: 1.077.530. Tunnelling shields. PHILIPP HOLZMANN A.G. Jan. 5, 1966, No. 563/66. Heading E1F. In a tunnelling shield a flexible sealing tube of plastics is housed concertinawise within an annular chamber at the rear periphery of the shield, the tube being sealable to the shield at one or the other ends of the chamber in accordance with operating conditions by radially expandable clamping rings. The tube leaves the rear of the chamber through an annular slit to emerge from the shield to be anchored against to make a watertight seal with the exterior of lubbing rings of the permanent tunnel lining erected to the rear of the shield to form a water impervious barrier between the shield and the lining. When the shield is advancing the tube is clamped to the shield by the forward clamping ring and by the rearward clamping ring when a new supply of tubing is to be joined in the chamber to payed out tubing.

A light source 6 is provided to generate charge carriers within the crystal which, in the arrangement shown, is situated in a resonant cavity 3. The constant drift field is supplied to indium electrodes, via a supply and monitoring device 2, by a high voltage source 5, while a high frequency generator 1 may apply electrical oscillations which generate the mechanical oscillations in the crystal due to its Piezo-electric properties. The h.f. generator 1 may be omitted, the crystal producing spontaneous acoustic oscillations is a sufficiently strong drift field.

Title: Method and apparatus for forming sheet material
IPC: B21D26/021
Filed: 1963-01-07
Abstract: 954,169. Cupping. AEROJET-GENERAL CORPORATION. Jan. 7, 1963 [March 26, 1962], No. 728/63. Heading B3Q. [Also in Division B5] A method of forming sheet material comprises filling a container with liquid, subjecting the liquid to an action or operation to produce a specified shape to its surface within the container and forcing a sheet of material into engagement with the shaped surface, the liquid thereby acting as a forming element and an hydraulic cushion. A die assembly 10 comprises a motor driven container 12, fluid 18 e.g. water with or without water soluble oils, and a sheet material 16 clamped to the top periphery of the container. The surface of the fluid is shaped by the rotation of the container and/or by mixers or other rotary devices or baffles in contact with the container or placed within the fluid prior to forcing the sheet into contact therewith, using e.g. conventional punches, rubber pads or explosive forming means. In an example an explosive charge 24 suspended by ropes or strands 26 above the centre of the sheet is detonated to form the sheet into the desired shape on the fluid. In further embodiments the fluid is solidified in the desired shape by means of a conventional refrigerator source or dry ice and after solidifying may be finish formed by a rotating scraper. Alternatively the fluid may be shaped using a contoured mould prior to solidifying, or solidified flat and subsequently formed by die-sinking, chiselling or scraping. The air between the sheet and die surface may be evacuated via an air vent and a vacuum pump. Liquids such as ethanol, methanol, diethyl ether, trimethylamine, phenylamine, piperidine, triethylene glycol or brine may be used singly or in combination, with or without water soluble oil and other corrosive preventatives and the liquid strengthened by an inert material, e.g. sand, sawdust or straw. Specification 925,422 is referred to.

Small temperature differences are measured using the arrangement shown in Fig. 1 which comprises four resistance thermometers 10 to 13 connected in a bridge circuit, two of the thermometers 10, 11 being temperature probes and the other two 12, 13 being placed on either side of a throttle valve 15 in a pipe 14 containing a flowing liquid. The bridge is used to measure the temperature change of a liquid flowing through a machine 16, and is balanced by adjusting valve 15 to obtain a null reading of galvanometer 18. The pressure difference across valve 15 is measured using a mercury manometer and the temperature difference determined using a calibration chart. Pipe 14 may be connected to the hydraulic input to machine 16 to supply the required high pressure liquid. Part of the pipe 14 is enclosed in an insulating box 17 which may also contain a second pipe for calibration purposes. The range of temperature differences which can be measured may be altered by using an alternative arrangement of resistance thermometers, Fig. 3 (not shown).

Title: I/o card selecting system of programmable controller
Inventor: TSUCHIYA HARUHIKO
IPC: G05B19/05
Filed: 1985-01-07
Abstract: PURPOSE:To reduce the number of lines required for the selection of I/O cards and to select a specific I/O card by connecting the I/O card on the basis of daisy chain connection and executing a specific sequence on the basis of an absolute address. CONSTITUTION:If the number of contacts of an I/O card when a bus line 5 is 8 bits, the address is latched after four clocks. Thus, the address values of all the I/O cards, i.e. the absolute addresses, are latched in each I/O card. At the service of a normal I/O card, i.e. at the execution of a normal sequence, data are transmitted to all the I/O cards sequentially on the basis of the daisy chain system. If data are to be transmitted to a certain I/O card, the address value of the I/O card to be transmitted is sent to a bus line at first, so that a data latch part of the I/O card corresponding to the address value assigned at the ON of power supply corresponds to the address value and only the I/O card is turned to transmissible status.
