Abstract: Carbon disulphide is reacted with pipecoline in the presence of a heavy metal salt to yield "carbon disulphide derivatives of alkylated piperidines."  The products are of the general formula RCSSM wherein M represents a metal and R an alkylated piperidine radicle, and in an example pipecoline is reacted with carbon disulphide and aqueous alkali, and zinc sulphate added to precipitate out the zinc pipecolyl dithiocarbamate.ALSO:Pipecoline dithiocarbamates.--Carbon disulphide is reacted with pipecoline to yield "carbon disulphide derivatives of alkylated piperidines."  The reaction may be characterized by the addition of an alkali or of a heavy metal salt.  The products obtained are assigned the general formula R-CSSM, wherein M represents a metal, dinitroaryl, arylmethylene, the group -CSSR or the group -CSR, and R is an alkylated piperidyl radicle.  In examples (1) pipecoline is reacted with carbon disulphide and aqueous alkali and the product oxidized by a mixture of hydrogen peroxide and sulphuric acid to dipipecolyl thiuram disulphide; (2) instead of oxidation as in (1) zinc sulphate is added to give zinc pipecolyl dithiocarbamate; (3) carbon disulphide is added to pipecoline in alcohol and then caustic soda and dinitrochlorbenzene added to give a dinitrophenyl ester of pipecolyldithiocarbamic acid; (4) instead of dinitrochlorbenzene as in (3) there is added benzal chloride to give phenylmethylene-bis-pipecolyl-dithiocarbamate; (5) pipecoline is added to carbon disulphide to give pipecolonium pipecolyl dithiocarbamate.  The production of dipipecolyl thiuram monosulphide is also specified.

Title: Subscriber connecting apparatus
IPC: H04L25/24
Filed: 1970-01-13
Abstract: 1298836 Telegraph exchanges COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 13 Jan 1970 [17 Jan 1969] 1706/70 Heading H4P In an apparatus for a telegraph switching system, particularly in an exchange, the transmission channels are divided into two sections each having a transmitter and a receiver connected in series to each section of the channel and the means are provided to break the connection between the two sections. Each combination of a transmitter and a receiver is connected as a repeater which enables the channel length to be doubled. Considering channel A which may be double current working, this is divided by a receiver RDR, Fig. 5, connected to through a single current line S, Ea to a transmitter EDE which retransmits double current signals derived from the exchange battery. Transmitters and receivers are controlled by a register (ER) (not shown) which develops inhibiting signals when this is not desired to forward calling signals to a subscriber. Signals from calling station RDR, Fig. 3, are sensed across diodes D1, D2. When the line E is negative, diode D1 1 is conductive hence transistors T1, T3, Fig. 3, are non-conductive. Diode D2 is non-conductive hence a transistor T2 is conductive and a capacitor C is discharged rendering a diode D5 reversed biased and a diode D3 forward biased hence earth potential is applied to lines ADR, IDR, ADE connected to register ER (not shown). As transistor T2 is non-conductive an output is not applied to line S, Ea. With a positive signal at E, diode D1 is reversed biased and transistors T1, T3 and T4 are conductive with T2 non-conductive hence a negative polarity is present on the lines ADR, IDR, ADE and a polarity p is applied to line S. The transmitters have output transistors (T3a, T4a), Fig. 4 (not shown), connected to provide positive or negative potential to line Sa from the exchange battery. If an earth potential is applied to line Ea, (T4a) is conductive to provide positive potential or if no potential is applied to line Ea, (T3a) is conductive and a negative potential is applied to output line Sa. Channel B operates similarly in the reverse direction.

Title: Improvements in and relating to thermionic amplifiers
IPC: H03F1/16
Filed: 1927-01-20
Abstract: 285,229. Igranic Electric Co., Ltd., Willans, P. W., and Hodgson, A. D'A. Jan. 20. 1927. Thermionic amplifiers.-The back - coupling effect, due to the use of a common HT supply for the several valves of a set, is neutralized by placing impedances across the HT supply and connecting an intermediate point to the grid return circuit or the anode return circuit of one or more of the valves. As shown, a resistancecoupled three-valve set has the valve-plates energized by a mains supply unit comprising condensers C, C<1> and a potentiometer P. Across the potentiometer the placed two impedances m<1>, m<2> in series, and the intermediate point is connected to the grid of the first valve through the grid leak. The point may be connected to a return circuit common to several valves. The impedance m<1> on the positive side may comprise a large condenser and the impedance m<2> a high resistance. The point j may be adjustable along the resistance, and a grid bias battery may be placed between the resistance and the negative lead. The resistance may have a condenser shunted across it. The connection applies to the grid a fraction of any alternating voltage present across the HT supply, and this feature is adjustable in phase so as to obviate instability of the set. In an alternative arrangement, the point instead of being connected to a grid circuit, is connected through a resistance to the plate of one of the valves, the HT current for this valve then passing through the impedance m<1>.

Title: Improvements in or relating to patterning mechanism for circular knitting machines
Inventor: FARMER ERNEST LEONARD
IPC: D04B15/68
Filed: 1964-01-05
Abstract: Needle selection is achieved on a circular machine by the provision of presser members 8 which are depressed to urge the outwardly sprung shanks of needle jacks 5 inwardly whereby the butts 6 of the latter avoid raising cams 7, Fig. 5 (not shown). The uninfluenced jacks are accordingly raised and needle selection achieved.  The presser members 8 are each provided with a single operating butt 9, and selection is made by raising or lowering the jack to bring its butt into alignment with the peripheral surface of one of a bank of selector discs 10, Fig. 1 (not shown).  For this purpose, prior to the needle selecting stage a cam 16 or 17 engages one of a number of butts 15 on each presser member and raises or lowers the presser so that its butt registers with one of the discs 10 to select or otherwise the needle.  The butts 15 on the presser members are so positioned and the cams 16, 17 actuated to cause various selections to be made such for example as the jack butts being aligned with alternate discs as the presser members are raised and with intermediate discs as the presser members are lowered.  The discs are rotated in timed relation to and by being coupled to the needle cylinder and the cams 16 and 19 are inserted by lever control mechanism 32, 33 actuated by a pattern band 31.

Filed: 1929-01-17
Abstract: 327,769. Standard Telephones & Cables, Ltd., (Busignies, H. G.). Jan. 17. 1929. Directive signalling.-In a direction finder, a visual indication of the direction of the transmitter is obtained from a galvanometer, the magnet of which is rotated with the goniometer coil. The goniometer coil C, Fig. 1, is successively coupled to each pair of aerial inductances B1, B2 as C is rotated, a vertical aerial A being utilized to eliminate the 180‹ ambiguity. The combined output from A and C is passed to the galvanometer coil D through a series of valves acting as highfrequency amplifiers; a local heterodyne is used for C, W. The galvanometer magnet V and search coil C are mounted on a common shaft Q, Fig. 3, which is rotated by an electric motor coupled to the sleeve M. The coil D is made in two parts, the pivots of the coil being at p p. Laminations F are mounted inside the coil and in the air gap between the poles of the magnet V. For each complete revolution of the shaft Q the received signal intensity will pass through a maximum when the plane of C coincides with the direction of the transmitter, the magnet V being arranged so that its field also coincides with this direction. The rectified current supplied to the coil D will be a maximum at the same moment: if the magnet is rotated at a sufficient speed, and the coil D has sufficient inertia. which is increased by damping, the effects combine, D taking up a position in which its field coincides with that of the magnet at the moment of maximum signal intensity. Coil D carries a circular scale e, Fig. 3, calibrated with a fixed index I, a direct visual indication of the direction of the transmitter being thus obtained. If the vertical antenna A is omitted, the magnet V must be rotated at twice the speed of coil C for the apparatus to function correctly.

Filed: 1939-01-19
Abstract: 524,003. Automatic exchange systems. POLLAK. J. E. (Associated Telephone & Telegraph Co.). Jan. 19, 1939, No. 1899. Drawings to Specification. [Class 40 (iv)] In a system having arrangements for printing information relating to calls, a switching device in response to a number of digits takes up a position representing the zone or exchange of the wanted party wherein it selects leads individual to letter magnets of a printing device to print the zone or exchange name instead of numbers. The system described is the same as that described in Specifications 516,408, 516,409 except for modifications enabling zone-name printing to be effected. In the printer-controller, the relay registers in which the two zone digits are stored are used to mark a bi-directional switch which over three wipers prepares the selection of three leads to letter magnets in the printer. As the printer control switch (OP2) in the aforesaid Specification makes provision only for two zone digits whereas three letters are now required, the position in DP2 used for printing a star (request for information) is used for the extra letter and the star is printed under the control of an additional relay.. If three letters do not identify the zone, discrimination is effected by the first zone digit to cause a fourth or further letters to be printed instead of the third dialled digit, a fourth or further wipers of the bi-directional switch being used for this purpose. As an alternative to the bidirectional switch, a hunting switch may be positioned according to a combination marking applied by a number of single motion switches set in accordance with the zone digits. The Provisional Specification describes also the transmission from the originating system translator of the exchange designation in a letter code.

Title: Improvements in and relating to steam power plant
IPC: F01K7/16
Filed: 1939-01-19
Abstract: 511,017. Elastic - fluid turbines. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 19, 1939, No. 1900. Convention date, Jan. 19, 1938. [Class 110 (iii)] A power plant, comprising a high pressure back pressure turbine 4-5, which supplies heating steam to a line 11 and bled steam to average pressure turbines 1, 2 and consumers 10, is controlled, during periods of abnormal-steam or electrical demands, by the high pressure turbine governor 21 which then influences the steam supply to the turbines 1, 2. If the steam demand in the lines 11 and 12 increases abnormally, the turbine 4, 5 speeds up, the spindle 33 of the governor 21, Fig. 2, raises, and the member 34 engages the contacts 36 to close the circuit of the motors 37, 38 which unload the governor springs of the turbines 1, 2 so that they slow up and shut down. A further increase in the speed of the turbine 4, 5 will cause the spindle 33 to operate the slide valve 25 and allow oil under pressure to lift the piston 26 which will close the regulating valves 28, 29 and reduce the turbine speed. The closing of these valves will lower the pressure in the line 11 still further and cause the back pressure regulator 23 to reach its limit position and become inoperative. The heating steam requirements are then met by steam supplied from the high pressure line 14 through the reducing valve 17. The lifting of the sleeve 26 stresses the spring 32 of an isodromic device 31, 32, which stress is gradually relieved by byepass in an oil brake 32. The slide valve 25 then returns to its neutral position with'the piston 26 in a new position. If the electrical demand now increases and the consumption and heating steam demands fall, the spindle 33 of the governor 21 moves downwards. This causes the piston 26 to move downwards, under the control of the slide valve 25, and open the regulating valves 28, 29. The pressure in the line 11 then rises and the back pressure regulator 23 again becomes operative. A further fall in the speed of the high pressure turbine will bring the member 34 in engagement with the contacts 35 to close the circuit of the motors 37, 38 which will reload the governor springs of the turbines 1, 2 so that they come into operation again. Lines 13, 15, 16 with reducing valves 14', 17, 18 allow steam to be supplied to the heating line 11 and consuming line 12 should any of the plant be out of commission.
