Abstract: 1507517 Hydrocarbyl substituted polyamines BP CHEMICALS Ltd 5 Aug 1976 [22 Aug 1975] 34912/75 Heading C2C [Also in Division C3] A method of preparing a hydrocarbyl substituted polyamine comprises the steps of (a) reacting a hydrocarnyl halide with an excess of a polyamine in the absence of an inorganic base or basic salt and in the presence or absence of a solvent, (b) allowing the reaction product to settle and separating a product-rich phase and an excess amine-rich phase, (c) recovering product from the product-rich phase by distillation preferably after first washing it with water, (d) neutralizing the excess amine-rich phase with an inorganic base or basic salt, and (e) recovering excess amine from the neutralized amine-rich phase and re-using the amine in a further step (a).  Using a base (e.g. NaOH or KOH) in step (d), the polyamine may be recovered by (i) distillation to remove water, any solvent and any polyamine breakdown products; (ii) filtration to remove precipitated salts. Using a basic salt (e.g. Na 2 CO 3 ) in step (d), the polyamine may be recovered by (i) addition of a solvent for the polyamine which forms an azeotrope with water, e.g. xylene, (ii) removal of the water by distillation, (iii) filtration to remove precipitated salt and (iv) fractionization of the polyaminexylene filtrate to give a xylene fraction, a polyamine fraction and a residue which is discarded.

The quenching may be carried out in oil or in a fused salt bath, the preferred austenitizing temperature being over 1400  DEG F.  After tempering as above the steel may be prestrained beyond its elastic limit to the extent of 1-6% and then strain aged below the tempering temperature.  The plastic pre-strain referred to above is preferably caused by applying a stress in the direction in which stress will occur during use of the part (e.g. compression or tensile stress when the part is to be used under compression or tension respectively).

Abstract: 1,037,476. Threshold circuits. LIQUIDOMETER CORPORATION. Aug. 26, 1964 [Aug. 29, 1963], No. 35074/64. Heading H3T. [Also in Division G1] Transistors 40 and 41, Fig. 8, are used as rectifiers having controlled threshold potentials. The circuit shown is that of a resistance meter (see Division G1) in which a magnet 24 (Fig. 9, not shown) is rotatable inside a ferromagnetic ring having three polepieces 120 degrees apart, one of which is wound with the coils 9b and 12, one with the coils 16c and 38 and one with the coils 15c and 39. It is required that the coils 38 and 39 become energized only when a predetermined degree of unbalance of the bridge constituted by the resistors 6, 7, 8a and 37 is exceeded. The resistances 42 and 43 between the base and collector of the respective transistors block them for low out-of-balance voltages, but allow them to function (as rectifiers) at higher voltages.

Title: Commutating and interrupting process, applicable particularly to high tension electric rectifiers and converters
IPC: H02M7/40
Filed: 1947-12-31
Abstract: 658,749. Switching systems; converting. TOULON, P. M. G. Dec. 31, 1947, No. 35103. Convention date, Jan. 8, 1946. [Classes 38 (ii) and 38 (iv)] To prevent sparking at interrupter contacts, more particularly at the brushes of a converter of the rotating brush type, a negative feed-back electric valve system is arranged to suppress the voltage across the contacts just prior to their closing and to suppress the current passing through the contacts just prior to their opening. As shown in Fig. 1 a load 202 is connected for a short period to a source 201 through a switch comprising a fixed contact 204 and a motordriven contact 203, sparking between which, as the moving contact engages and disengages the fixed, it is desired to prevent. For this purpose the contacts are shunted by auxiliary contacts 214, 215 having a slight lead on contacts 203, 204 and in series with a potential divider 216, 217, so that just prior to closing of the main contacts 203, 204 the auxiliary contacts are closed and a fraction of the voltage then across the main contacts appears across 216. After amplification at 219 this voltage is applied over contact 212 of a synchronously driven changeover switch 212, 213 to the grid of a valve 210 the anode current change of which induces in a coupled coil 207 in the load circuit a voltage annulling that across the main contacts. A further amplifier 218, energized by a resistor 206 in the load circuit, is connected to the grid of valve 210 by contact 213 of the changeover switch as the auxiliary contacts 214, 215 separate, whereby the valve supplies to coil 207 a voltage such as to reduce the load current to zero. Fig. 3 shows an A.C. to D.C. converter comprising transformers 5-10, 5<SP>1</SP>-10<SP>1</SP> so connected to a three-phase source 1-4 as to give a twelve-phase output. The secondary winding of each transformer has five equally-spaced tappings and the total sixty tappings are connected to two staggered commutators 19, 20 having thirty segments each. The D.C. output is taken from pairs of main brushes 27, 28, 271, 281, which rotate about the commutators, through valves 29, 30, 291, 30<SP>1</SP>, which are gridcontrolled for current regulation by a controller 28<SP>11</SP> responsive to the voltage drop across shunts in the output conductors. Auxiliary brushes 31, 32, 31<SP>1</SP>, 32<SP>1</SP> leading the main brushes and directly or capacitively engaging the two commutators may also control the device 28<SP>11</SP>. The commutating voltages are supplied by a synchronously-driven generator 33 and injected into the brush leads by transformers 34, 341.

Patent GB-1515572-A (GB)
Title: Refrigeration heat reclaiming system
IPC: F25B25/02
Filed: 1975-08-28
Abstract: Between a compressor (20) and a condenser (11) of the refrigeration installation, the refrigerant vapour flows through a heat recovery heat exchanger (25). The refrigerant vapour delivered by the compressor (20) is mixed with a concentrated absorption medium solution which is supplied e.g. by an injection device (39) and which absorbs a part of the compressed refrigerant vapour, as a result of which the temperature of the mixture flowing through the heat exchanger (25) is increased. After the heat exchanger (25), the solution diluted with refrigerant is separated from the remaining refrigerant vapour in a separator (30). In a concentrating device (35), the solution is subjected to the compressor inlet pressure in order to boil refrigerant off from the solution. The heat necessary for this is extracted from the remaining refrigerant vapour which at least partially condenses in the process. The solution, concentrated again, is supplied to the injection device (39) again. A part of the waste heat of the installation is thus delivered at a higher useful temperature level without the compressor having to be operated in an uneconomical compression range which is detrimental to the refrigerant. <IMAGE>

Abstract: 522,569. Speed governors. C. A. V., Ltd., and NICOLLS, W. E. W. Dec. 9, 1938, No. 35942 [Class 57] In a regulating-device for a fuel-injection pump comprising a controlling-member movable into maximum-fuel position by a spring, and movable into minimum-fuel and no-fuel positions by a displaceable member responsive to fluid-pressure, and a centrifugal governor respectively, the governor is arranged to move the controlling-member independently of the displaceable member, the arrangement enabling a lightly constructed governor to be employed. In the device shown in the Figure, a sliding rod a for controlling the output of the fuel-pump b is urged by a spring e into maximum-fuel position determined by an adjustable stop f. The rod e is pivoted to a link j having ears m supporting a sliding rod k which is provided with a nut n for engaging one of the ears, and is connected to a diaphragm h responsive to the vacuum in a chamber i which communicates with a controllable constriction in the airsupply. In the minimum-fuel position of the rod a the diaphragm moves into contact with a plunger y loaded by a spring z which is stiffer than the spring e. A centrifugal governor p on the pump-shaft q comprises an axiallymovable member u which engages a lever s having a finger w for engaging an adjustable stop x on another lever r which is pivotally connected to the link j. When the governor becomes effective the link j moves the rod a into the no-fuel position, but the rod k and the diaphragm are not displaced, the governor being thereby relieved from moving the diaphragm and compressing the spring z. The link j can be operated under control of the driver by means comprising a lever 2.
