Title: Improvements in or relating to pesticidal compositions
Filed: 1946-07-18
Abstract: N,N1-dithioamines having the general formula R-S-S-R1, where R and R1 are secondary or tertiary amino groups, are prepared by reacting an amine having at least one active hydrogen with sulphur chloride in the presence of a reaction diluent.  The resulting dithioamine may be converted into a N,N1-trithioamine by reaction with sulphur at elevated temperature and this in turn may be converted into a tetrathioamine by reaction with further sulphur in a similar manner. Dithiodiethylamine may be prepared by reacting two molecular equivalents of diethylamine with a slight excess over one molecular equivalent of sulphur chloride in the presence of sodium hydroxide and benzene.  After removal of benzene by steam distillation and sodium chloride by the addition of water, the water-insoluble N,N1-dithiodiethylamine separates and can be converted into the trithioamine by heating with sulphur at 120 DEG  C. Other polythioamines mentioned are N,N1-dithiodibutylamine, N,N1-trithiodibutylamine, N,N1-dithiodimethylamine, N,N1 - dithiodipropylamine, N,N1 - dithiodiisopropylamine, N,N1 - dithiodiisoamylamine, N,N1 - dithiocyclohexylamine, N,N1 - trithiomorpholine, N,N1 - tetrathiomorpholine, N,N1 - dithiopiperidine, N,N1 - dithiobenzylamine, N,N1-dithioaniline.ALSO:A bactericidal, fungicidal or insecticidal composition comprises a small proportion of a N,N1-polythioamine of the general formula R-Sx-R1 in which R and R1 are secondary or tertiary amino groups and x is 2, 3 or 4 in admixture with a fluent carrier with which the active ingredient forms a dust or a dispersion.  Specified compounds are N,N1-dithiodiethylamine N,N1-trithiodiethylamine, N,N1-dithiodibutylamine, N,N1-trithiobutylamine, N,N1-dithiodimethylamine, N,N1-dithiodiprolylamine, N,N1-dithiodiisopropylamine, N,N1-dithiodiisoamylamine, N,N1-dithiocyclohexylamine, N,N1-trithiomorpholine, N,N1-tetrathiomorpholine, N,N1-dithiopiperidine, N,N1-dithiobenzylamine and N,N1-dithioaniline.  The polythioamines may be used in combination with other active ingredients such as metallic arsenicals, fluosilicates, organic thiocyanates, phenothiazine, nicotine, pyrethrum, rotenone and isobutylindecylenamide.  These mixtures may be diluted with bentonite, talc, calcium carbonate, and tricalcium phosphate or may be suspended in petroleum hydrocarbons, water or alcohol. Dispersing agents such as lauryl alcohol, long-chain alcohol sulphates, sulphated or sulphonated alcohols, sodium salts of sulphated alcohols, sulphonated aromatic or alkylaryl derivatives, hexahydric alcohols, esters of fatty acids, pine oils, soybean lecithin, or adhesives or sticking agents such as milk products, flour, gelatine and fish oils may also be added.

Patent GB-633901-A (GB)
Title: Improvements in and relating to clutch mechanisms for transmitting rotary motion
IPC: F16D41/12
Filed: 1947-08-07
Abstract: 633,901. Operating ratchet clutches. NICHOLSON, A. C. Aug. 7, 1947, No. 21529. [Class 80 (ii)] A ratchet clutch particularly for driving mechanism on an agricultural implement from one of the wheels thereof is adapted to be put into and out of operation by successive operations of a control member from a remote point. The driven member 8 has ratchet teeth 9 co-operating with a pawl 14 on a driving member 10 secured to a wheel 13. A disc 11 is mounted for relative rotation with respect to the disc 10 and has two pegs 35 thereon for co-operation with either a notch 40 in the tail piece 16 of pawl 14 or a notch 41 in another pawl 36 carried by the disc 10. The disc 11 has also four projections 24 on its periphery for co-operation with a control member 7 and partially masked by a cam portion 25 on the disc 10 with a recessed portion and cam slopes 32, 33. As shown in Fig. 3 the pawl 14 is engaged with the ratchet wheel 9 so that the drive from the wheel 13 is effective in one direction and the disc 11 is carried around with the disc 10 by the engagement of a peg 35 with the pawl 36. If the control member 7 is operated to a position shown in full lines it rides down the slope 32 of cam 25 and engages a projection 24 of the disc 11 and effects a relative rotation of the disc 11 with respect to the disc 10 until it is lifted by the cam slope 33. This results in the disengagement of the peg 35 from the pawl 36 and its engagement with the notch 40 of pawl 14 to lift and hold this pawl out of engagement with the teeth 9 and so stop the drive from wheel 13, the control member 7 being released and returned to the dotted line position. On a further operation of the member 7 it is moved to engage another projection 24 and to cause the one peg 35 to release pawl 14 to the other peg 35 to engage pawl 36 so that the drive is resumed. In a modified arrangement a further separate holding pawl is provided for holding the disc 11 in a position in which the main pawl 14 is disengaged instead of this operation being effected by the engagement of a peg 35 with the notch 40 of pawl 14.

Title: Method of and apparatus for control of finishing pressure in the die-casting of metals
IPC: B22D17/32
Filed: 1975-05-20
Abstract: 1505102 Pressure die casting machines BUEHLER AG Gebr 20 May 1975 [22 May 1974] 21538/75 Heading B3F In a pressure die casting machine in which the pressure applied by an hydraulic fluid to the injection piston.during the mould filling phase is determined by a predetermined gas pressure, adjustment of the gas pressure automatically results in adjustment of the increased pressure applied to the injection piston during solidification of the casting. In the embodiment shown, a pressure gas container 20 is connected to the inlet of a piston accumulator 17 whose outlet communicates with a line 42, 23, 15 extending from a pump 43 for the hydraulic fluid to a multiplier cylinder 9. A valve 25 is located in the line 42, 23, 15 and has a slidable member 27 provided with a bore 29. The member 27 is biased to its open position by a spring 34. During the mould filling phase, the hydraulic pressure in the line 15, 23 acts on a piston 6 via a bore 10 in the multiplier piston 8, the pressure exerted on the piston 6 being determined by the gas pressure in the container 20. If it is required to change the pressure during the mould filling phase, e.g. to reduce it, the pressure in the container 20 is reduced by means of a valve 22. This results in a piston 101 in a cylinder 100 moving to the left under the influence of the hydraulic pressure in the chamber 108. This causes a control cone 37 to move further off its seat 36 and permits an increased flow of hydraulic fluid from a pressure chamber 33 to a tank 45 resulting in a movement of the member 27 in its closing direction and thus a proportional pressure reduction at the outlet 24 of the valve 25. Thus the hydraulic pressure applied to the multiplier piston 8 during solidification of the casting is reduced.

Title: Improved Method of and Circuit Arrangement for High Voltage Testing.
Inventor: LONGWORTH DAVID PHILIP
IPC: G01R31/333
Filed: 1966-05-16
Abstract: 1,153,492. Testing switchgear. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 21, 1967 [May 16, 1966], No.21667/66. Heading G1U. Electric switchgear is tested by a method in which high amplitude alternating current from a power source is applied to the switchgear followed by high voltage from an energised LC series combination, this high voltage subsequently being isolated. An additional alternating current of similar frequency and smaller amplitude to the first from a separate source is applied to the switchgear throughout the duration of the test. A power circuit breaker S2 under test is supplied with high current equivalent to the rated short circuit current from a source G1 via an autotransformer T1 through an auxiliary breaker S1, while a series oscillatory LC circuit initially charged from a high voltage source at 3, 4 is connected across the test breaker by firing a spark gap SP at a predetermined instant, to apply a transient recovery voltage immediately before the high current initially applied to the breaker has reached its final zero. An alternating 'steady' recovery voltage is applied continuously to the breaker from a source G2 via an autotransformer T2, and this source is isolated from the LC circuit after the transient has been applied by operating a switch S3. A resistor R facilititates phase matching between T1 and T2.

Filed: 1970-05-08
Abstract: 1281646 Supply device for a heart stimulator PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 8 May 1970 [13 May 1969] 22362/70 Heading A5R A supply device for an intracorporal heart stimulator comprises a sealed casing within which is disposed an oscillatary rotor in the field of a magnet and means for transmitting to said rotor the movement of the heart, which means comprise a rotatable member coaxial with said rotor, a rotatable vane coupled with the rotatable member, and means for controlling the oscillatory displacement of the vane in accordance with the movements of the heart. As shown the airtight casing 1 accommodates an annular magnetic circuit 2a associated with a winding 2b and having an air gap accommodating a permanent-magnet rotor 3 which is magnetised in a direction at right angles to its axis of rotation. Two auxiliary magnets 4 produce a return magnetic-couple for the rotor.  A rotatable member 7 on the rotor is provided with teeth which mesh with the gear wheel 9 associated with a rotatable vane 11. The space within the cylinder 12 enclosing the vane 11 is divided into two pairs of equalvolume chambers (13a, 13b and 14a, 14b) Fig. 2 (not shown), in such a way that the volumes of one pair vary in a complementary manner to the volumes of the other pair in accordance with the rotation of the vane 11. The pair of chambers (13a, 13b) are connected to a plastic bag (18), Fig. 3 (not shown), arranged at the tip of the heart (17), and the pair of chambers (14a, 14b) are connected by a flexible tube 16 to an elastic bag (19) forming an expansion chamber. Initially the bag (18) is filled with liquid and at each systole the bag (18) is compressed between the tip of the heart and the surrounding tissues, thus expelling the liquid along the tube (15) into the chambers (13a 13b) then into the chambers (14a, 14b) and into the tube 16 towards the elastic bag (19), the vane 11, and therefore the rotor 3, being caused to perform an oscillating movement. The winding 2b of the magnetic circuit 2a is connected to the terminals of a capacitor (not shown), so that a tuned oscillatory circuit is formed. An electric switch and a stimulator (not shown) may be accommodated inside the casing 1, one of the electrodes for transmitting the pulses of the stimulator may be formed by the casing 1, the other electrode may be fixed to the flexible bag (18) if the liquid is conductive. The vane 11 may be made of magnetic material and associated with two external symmetrical magnets 10 obviating the use of a shaft passing through the cylinder wall.
