Abstract: 1,232,230. Jointing by stamping; making electrical connections. THOMAS & BETTS CORP. 20 Nov., 1968 [14 Dec., 1967], No. 55169/68. Headings B3A and B3Q. [Also in Divisions D1 and H2] A sleeve coupling 20, e.g. for connecting together two conductors comprises inner and outer metal sleeves 22, 24 disposed coaxially and sealed together as by welding, at their ends 34 to define an enclosed space 32, a passageway 40 in the outer sleeve 22 permitting the application to the space 32 of a high pressure medium from a source such as 44 in order to crimp inner sleeve 24 to conductors (not shown) inserted in each end of sleeve 24. Outer sleeve 22 is made of rigid Al or alloy, while inner sleeve 24 is of more malleable Al alloy and has a central transverse partition 26. The high pressure medium employed may be hydraulic fluid (in which case space 32 may be initially filled with such fluid), or gas, or particulate solid material such as silicon; or lengths of silicone rubber may be forced into space 32 by an hydraulic ram; or an explosive material within or outside the coupling may be electrically detonated to produce the crimping pressure or a substance which produces a gas on being heated may be located within the coupling. After crimping, the material used may be retained in space 32 by plugging passageway 40, and may be selected to enhance or inhibit cooling of the coupling. In place of welding, the ends of the sleeves may be sealed together by crimping or rolling in each case sealing rings being interposed between the sleeves. Partition 26 may extend radially to outer sleeve 22, in which case two enclosed spaces 32, each having a pressure-admitting passage 40, are formed; and a further pair of coaxial sleeves, similarly sealed together and disposed at right angles to the main coupling, may be provided to act as a branch connector. The inner and outer sleeves 72, 74, Fig. 9, may be integrally formed in one longitudinal region 76; this embodiment incorporates corona discharge rings 80. The coupling may be used to join two cables, or to connect a cable to a terminal member; alternatively, one end of the outer sleeve may be formed as a clevis or other fastening device. For connecting underground cables, the coupling may be provided with a protective insulating sheath.

Abstract: 1,232,431. Radio signalling. HOFFMAN ELECTRONICS CORP. 26 June, 1968 [3 July, 1967], No. 30539/68. Heading H4L. At the airborne receiver in a TACAN navigation system, the received signal, consisting of a series of pulses at a given repetition frequency coded in dots and dashes to identify the ground beacon, controls a monostable device 10 which produces a square-wave output in which each pulse has a duration of one half of the spacing between incoming signal pulses. The output of monostable 10 is supplied to a filter 12 tuned to the repetition frequency of the pulses, i.e. 1350 Hz., and the resulting signal, which has a magnitude representing the magnitude of the 1350 Hz. component of the square-wave is supplied to a peak detector 14 so that a gate 16 is opened each time the output of the filter 12 exceeds a predetermined level. When the gate 16 is opened it starts a 1350 Hz. oscillator 18 the output of the oscillator being amplified at 20 and supplied to the audio system 24 of the aircraft.

Abstract: 1,233,288. Coating webs. STEWART-WARNER CORP. 9 July, 1969 [10 July, 1968], No. 34650/69. Heading D1L. In a web coating process, the coating material is supplied to the applicator for a pre-set period and the supply is then cut off for a period inversely proportional to the mean rate at which the web passes over the applicator; this cycle of events being continuously repeated. As particularly described, a counter initiates spraying of oil onto an absorbent applicator roll after a predetermined lengths of a metal web being coated therefrom has passed. During spraying the counter is rendered inoperative. The spray period is advantageously short in relation to the "off" period. Electrical control is described, in which the spray and off periods are both adjustable, whereby variable controlled coating thickness is possible. Both sides of the web may be coated simultaneously.

Abstract: 1,251,678. Determination of reaction rate. DOW CHEMICAL CO. 3 Dec., 1968 [4 Dec., 1967], No. 57290/68. Heading B1X. The rate of a chemical reaction in which gas is evolved or consumed is determined by passing gas from source 50 at a predetermined rate through a reaction assembly which includes means 10 containing sample 20, interrupting the flow of gas into the assembly by operation of valve 60 so isolating the assembly, circulating the gas within the assembly by means of pump 75, measuring the pressure change by means 90 throughout at least one present interval of time, and operating valve 60 to restore the flow of gas through the assembly. The temperature of the sample may be controlled by heating bath 35. Calibration means 120 changes the internal volume of the system by known amounts giving corresponding changes in pressure. The pressure changes may be measured at different temperatures, the temperatures being measured by thermocouple 30 in well 28 of means 10; at varying magnetic flux, measured by means 175; and at varying amounts of u-v radiation emitted by source 200. All experimental conditions may be controlled by timing means 70. Measurements may be fed to intelligence processing means 140, which may record a sequence of spaced traces varying with time, each trace corresponding to measurement of one of the other parameters. There is reference to the rate of decomposition of 2-oxazolidinone both alone and in the presence of its 3-sodium derivative.

A method of mechanically producing pulp comprises feeding substantially completely saturated wood chips to a disc defibrator, admitting steam to the defibrator so that the temperature of the steam is 100-150‹C, feeding water to the defibrator ahead of the defibrating members in such quantity that the pulp issuing is of 40-15% consistency, defibrating the chips, immediately blowing out the pulp, and refining it, the time for heating and defibration being kept low to avoid discolouration. The refining may be at 70- 100‹C, or in two stages, at 70-100‹C and, subsequently, at 40-70‹C. The chips may be saturated with water by steeping and draining. This may also be effected by treating with steam at atmospheric pressure, compressing the chips, and allowing them to expand under water at least once, and draining. Various reagents may be added to the steam e.g. SO 2 , O 2 , or to the water used for saturation of the chips or for addition to the defibrated chips e.g. surface-active agents, terpenes, resins, terpentine, bleaching agents. The surface-active agents may be anionic e.g. alkyl-aryl sulphonates, or non-ionic e.g. alkyl-aryl-polyglycol ethers.
