Abstract: 1,142,535. Prestressed reinforced concrete. ROCLA CONCRETE PIPES Ltd. 4 April, 1967 [6 April, 1966], No. 15435/67. Heading B5A. Prestressed reinforced concrete pipes are formed by forming a concrete pipe containing reinforcement in a hollow resilient mould, applying pressure inside the pipe before the concrete hardens and then releasing the pressure and removing the pipe from the mould. As described the mould comprises a rigid casing 2 and a resilient moulding surface 1 preferably of reinforced glass fibre. End pieces 7, 6 contain holes 10 in which the reinforcement 8A is located; the concrete pipe 8B being formed round the reinforcement by any suitable process such as rotational casting. A lining 11 impermeable to water is placed over the inner face of the concrete and a bulkhead assembly 12 comprising a tube 14 with ends 16 and 18 is inserted into the mould so that end 16 sealably abuts end 7. A further bulkhead 22 with attached rim 24 seals the other end of the water cavity (13) and is attached to end member 18 by bolt 19 and nut 27. Suitable sealing rings are supplied at each join to prevent leakage of water. Warm water (to speed the setting of the concrete) is supplied under pressure through pipe 30 and the pressure maintained until the concrete has set. The water pressure is released and the bulkhead assembly 12 and also rings 7 and 6 are removed. Steel discs 31, 32 fitted with rubber gaskets are then fitted, 31 to the right hand end of the pipe and 32 (which contains a water inlet) to the right hand end of rigid casing 2.

Abstract: 1,201,481. Automatic temperature control systems. BRITISH THERMOSTAT CO. Ltd. July 3, 1968 [April 5, 1967], No.15556/67. Heading G3R. An actuator providing a mechanical output for the operation of a valve or similar mechanical control device comprises a temperature responsive member mechanically connected to the valve or other device, an electric heater associated with the temperature responsive member, and temperature sensing means in thermal relationship to the temperature responsive member and connected to control means to regulate the energy to the electric heater in accordance with one or more variables one of which is the temperature of the responsive member.  A bellows member 2 actuating a valve 4 controlling a gas supply has a heater 9 supplied from an amplifier according to the temperature measured by an element 8. Another input to the amplifier is derived from a sensing element 10 responsive to a heat exchanger 7 output temperature. In the absence of an output from element 10 the bellows 2 assumes a position dependent on the set point of element 8 which is modified by the element 10 to open or close the valve 4 in accordance with the heat exchanger temperature. The system may be arranged to adjust the temperature of the heat exchanger in accordance with outside conditions, and a bridge or potentiometer circuit may be associated with the amplifier so that other features e.g. room or boiler temperature may be incorporated. Sensing elements 8, 10 may be temperature dependent resistors, thermocouples, transistors, or other temperature dependent devices. The system may be modified to control humidity or pressure, or it may be arranged to act at a remote control device by substituting a manually adjustable resistor for the element 10. The bellows may be replaced by a diaphragm, a bi-metallic element or other differential expansion device.

Filed: 1963-04-19
Abstract: The invention comprises compounds of the formula <FORM:0999893/C2/1> in which R represents an alkyl, cycloalkyl, aryl, aralkyl or heterocyclic group and n is 0, 1 or 2. Specified examples of R include methyl, pentyl, cyclohexyl, chloromethyl, alkoxycarbonyl-methyl, benzyl, chlorobenzyl, nitrobenzyl, phenyl, halophenyl, nitrophenyl, alkoxyphenyl, thiazolyl and benzthiazolyl. The phenyl nucleus may carry substituents, e.g. a halogen atom or a sulphonic acid group.  The compounds in which n is 0 may be prepared by condensing a 1-halogen-2,6-dinitrobenzene with a compound RSH, or by condensing a 2,6-dinitrobenzene-1-thiol with a compound R-Hal, in which Hal is a halogen atom.  The compounds in which n is 1 or 2 may be prepared by oxidizing the compounds in which n is 0, e.g. with hydrogen peroxide, a per-acid or nitric acid.  The compounds in which n is 2 may also be prepared by reacting a 2,6-dinitro-1-halogen-benzene with a sulphinate of the formula RSO2M, in which M is a salt-forming radical, or by reacting a 2,6-dinitrobenzene substituted in the 1-position with a group SO2M with a compound of the formula R-Hal.  In the examples:  (1) 1-chloro-2,6-dinitrobenzene and pentanethiol yield 2,6 - dinitrophenyl n-pentyl sulphide, which may then be oxidized with nitric acid to yield 2,6-di-nitrophenyl n-pentyl sulphoxide; (2) 2,6-dinitrophenyl n-pentyl sulphide is oxidized to 2,6-dinitrophenyl n-pentyl sulphone with hydrogen peroxide; (3) 1-chloro-2,6-dinitrobenzene and toluene-p-thiol yield 2,6-dinitrophenyl p-tolyl sulphide, which is successively oxidized with hydrogen peroxide to the corresponding sulphoxide and sulphone. Other specified products are 4-chloro-2,6-dinitrophenyl p-chlorophenyl sulphide, sulphoxide and sulphone, n-butyl 4 - chloro - 2,6 - dinitrophenyl sulphoxide and sulphone, 2,6-dinitrodiphenyl sulphide, sulphoxide and sulphone, p-chlorophenyl 2,6-dinitriphenyl sulphide, sulphoxide and sulphone, n-butyl 2,6-dinitrophenyl sulphide, sulphoxide and sulphone, 2,6-dinitrophenyl isobutyl sulphide, sulphoxide and sulphone, and 4-chloro-2,6-dinitrodiphenyl sulphide, sulphoxide and sulphone.  The products are useful as fungicides (see Division A5).ALSO:As components of fungicidal compositions, use is made of compounds of the formula <FORM:0999893/A5-A6/1> in which n is 0, 1 or 2 and R is an alkyl, cycloalkyl, aralkyl, aryl or heterocyclic radical (see Division C2). The specified compounds include 2,6-dinitrophenyl n-pentyl sulphide, sulphoxide and sulphone, 2,6-dinitrophenyl p-tolyl sulphide, sulphoxide and sulphone, 4-chloro-2,6-dinitrophenyl p-chlorophenyl sulphide, sulphoxide and sulphone, and 2,6-dinitrophenyl sulphide, sulphoxide and sulphone.  The compositions may be formulated as dusting powders, dispersions, emulsions, smokes and aerosols with the aid of suitable diluents, some of which are specified, and they may include other fungicides and insecticides, e.g. DDT, benzene hexachloride, dinocap, dinoseb dimethacrylate, and sulphur.
