Title: Transistor switch
IPC: H03K17/16
Filed: 1963-05-20
Abstract: 1,010,085. Transistor switching circuits. BROWN, BOVERI & CO. Ltd. May 20, 1963 [May 22, 1962], No. 20022/63. Heading H3T. In a transistor switching circuit in which transistor 1 is rendered conducting and blocked by signals applied to its base a further transistor 8 of opposite conductivity type to transistor 1 is connected with its emitter-collector path in the emitter-base circuit of transistor and arranged so as to act as a shunt for the collectorbase leakage current of transistor 1 when the latter is blocked. When transistor 1 is conducting, transistor 8 is biased into a non- conductive condition and provides a high shunt resistance for transistor 1. A two-stage switching circuit is shown in Fig. 2, wherein transistor 8 again acts as a shunt resistance for the second stage transistor 1 of the circuit. When a negative signal is applied to terminal 6, transistors 1À1 and 1 conduct and transistor 8 is blocked and when a positive signal is applied to terminal 6 transistors 1À1 and 1 are blocked and transistor 8 conducts to provide a shunt path for the collector-base leakage current of transistor 1. The load 2 may be a tripping element for a switch.

Abstract: 850,632. Magnetic recording apparatus. AUTOPHON A.G. June 23, 1958 [June 27, 1957], No. 20080/58. Addition to 824,469. Class 40 (2). [Also in Group XXXIX] In a transmitting arrangement of the type disclosed in the main patent, in which impulses are emitted by a magnetic reading head which scans information carriers bearing recordings of the required impulses, the reading head has at least two poles disposed in a plane at right angles to the direction of scanning. The recordings may be mechanical recordings or magnetic recordings. Embodiments using mechanical recordings.- These recordings consist of raised portions 7 on a drum 6 (Fig. 2), which raised portions are indicated by hatching in Fig. 1. Each of the two poles 4 of the reading head (Fig. 2) has a winding 3, and the magnetic circuit passes from each of the poles 4 via the information carrier to the permanent magnet 2. The raised portions 7 are so disposed that as the head scans from left to right (Fig. 1) they are either under both poles 4 simultaneously (neutral position), or under only one pole (extreme positions). The flux produced in the upper and lower poles is indicated at # o  and # u , respectively, and the resulting output voltage from the reading head at S. The latter will be seen to consist of rectangular positive and negative impulses. Alternative forms of reading head having two auxiliary poles and one auxiliary pole are shown in Figs. 3 and 4, respectively. In the arrangement of Fig. 6 separate records are provided for scanning by each of the poles 4, the lower edge of area 13 and the upper edge of area 15 forming a pair of such records. Embodiment using magnetic recordings.-The two extreme positions of the mechanical recordings are replaced by portions of the drum magnetised in the two opposite directions (Fig. 7), and the neutral position by an absence of magnetisation. The reading head is much simpler, since it requires neither a permanent magnet nor auxiliary poles. Apparatus for pre-setting trains of impulses.- For each of the number of trains to be set up there is provided a drum 23 (Fig. 8), consisting of three discs, rotatable about the shaft 30 under control of a gear 25 and the toothed segment 26 connected to a setting lever 28. The levers 28 are set so that the raised portions on the drum corresponding to the impulse trains required are aligned along the path to be scanned by the reading head shown on the right of the Figure. Alternatively, for each of the number of trains to be set up there may be provided three sectors 34 (Fig. 9), each arranged for pivotal displacement on a shaft 37 into a middle, upper, or lower position, so as to form, in conjunction with the stationary intermediate portions 35, recordings of all the possible impulse trains. Cylinders 31, one for each of the number of impulse trains to be set up, control the sectors 34 by means of notches 32 of three different depths. Specification 850,631 is referred to.

Abstract: 1458633 Dehalogenation of aromatic compounds IMPERIAL CHEMICAL INDUSTRIES Ltd 31 July 1975 [17 Sept 1974 15 May 1975] 40420/74 and 20618/75 Heading C2C [Also in Division C5] A process for dehalogenating a water immiscible or sparingly soluble aromatic (including heteroaromatic) compound containing at least one chlorine or bromine atom as a nuclear substituent comprises contacting the said compound with an aqueous solution of a formic acid salt in the presence of a hydrogenation catalyst and a surface active agent (as hereinafter defined). By the term surface active agent is meant any substance which, when dissolved in water lowers its surface energy. It has been found that reductive dehalogenation i.e. a replacement of a chlorine or bromine atom by a hydrogen atom is favoured by use of an excess of formic acid salt i.e. greater than 3 mole equivalents and a pH near to neutrality whereas the portionwise addition of from 1À0 to 3À0 mole equivalents of formic acid salt for each chlorine or bromine atom present as nuclear substituent favours the formation of internuclear bonds especially under strongly alkaline conditions.

Title: A process for the manufacture of ammonium sulphate
IPC: C01C1/242
Filed: 1933-07-24
Abstract: Ammonium sulphate is obtained by mixing acid sludge from the refining of petroleum &c. <PICT:0405556/III/1> with ammonia, separating oil from the aqueous liquid produced and thereafter evaporating the liquid.  The liquid is preferably maintained slightly acid and the temperature is preferably maintained below 95 DEG  C., say 80--90 DEG C.  Gaseous, aqueous or anhydrous liquid ammonia may be employed. The process may be conducted under atmospheric or sub-atmospheric pressure.  Acid sludge from a tank 1 and aqueous ammonia from a tank 5 are continuously fed into a stirred neutraliser 2 together if necessary with water from a pipe 8.  The contents of the neutralizer oil continuously withdrawn to an apparatus 10, where a thin oil is separated and thence via a pipe 14 to an oil filter 15 which may contain sand, clay, charcoal, glass, wool, silica gel or the like whereby the remainder of the entrained oil is either separated or agglomerated for separation in a secondary separating tank 16.  The ammonium sulphate, freed from entrained oil, passes to an evaporator 17 where evaporation and crystallisation is effected.  A part of the liquor is continuously withdrawn through a line 18 to a separator 19 where oil forced out of solution by the evaporation is eliminated, the liquor being returned by a pipe 21.  A part of the liquid with crystals in suspension is continuously withdrawn to a centrifuge or filter 22, the liquor separating from the crystals returning to the evaporator.  The neutraliser 2 is cooled by returning liquor from the pipe 14 and/or the evaporator 17 via a cooler 26.  The medium in the neutraliser is preferably maintained nearly saturated with ammonium sulphate.  The oil filtering may be replaced by centrifuging or by treatment with a suitable organic solvent, e.g. carbon tetrachloride.
