Title: Improvements in or relating to steam installations
IPC: A44B19/26
Filed: 1934-03-19
Abstract: 422,156. Power-generating systems. SULZER FRERES SOC. ANON., Winterthur, Switzerland. March 19, 1934, No. 8553. Convention date, March 18, 1933. [Class 122 (iii)] To prevent the corrosive action of oxygen and carbonic acid in the presence of saturated steam in steam power installations, at least part of the working medium in the form of steam, at a point beyond that where the medium performs useful work, is brought into contact with one or more liquid agents which effect the separation of the impurities in the medium before it enters the condenser. In the plant shown, steam from the generator 1 passes through a superheater to a turbine 3 which exhausts to a condenser 4. Pumps 6, 7 pass the condensate through a storage tank back to the boiler. A supplementary feed pump 9 is provided. A part of the exhaust only in the case of large pipes, passes through vessels 12, 13 containing calcium hydrate and sodium sulphite respectively. The carbonic acid turns the hydrate into carbonate which is deposited ; the oxygen turns the sulphite into sulphate which can be removed. Vessels or batteries may be arranged in parallel so that one may be used when the other is being cleaned, &c. The vessels may be temporarily or intermittently connected into the system. When several liquids are used, they may be separate or mixed in a single vessel. Pure liquid agents may be used in lieu of agents in solution. The vessels may be replaced by a pipe system, or the steam pipes themselves may contain the agents. The Specification as open to inspection under Sect. 91 states that the steam may be passed through one or more agents before reaching the superheater. This subject-matter does not appear in the Specification as accepted.

Title: Control of magnetic core elements
IPC: H03K3/45
Filed: 1967-02-23
Abstract: 1,119,304. Circuits employing bi-stable magnetic elements. SOCIETE TECHNIQUE POUR L'INDUSTRIE NOUVELLE S.A. 23 Feb., 1967 [25 March, 1966], No. 8597/67. Heading H3B. In an array of magnetic cores having a substantially rectangular hysteresis loop which cores are switched by coincident currents applied to drive wires threading the cores, a common erase wire threads all the cores and current is fed to the erase wire for a period of time which covers the starts of the currents in the drive wires. The negative erase current, Fig. 5 (not shown), is of such magnitude that it not only returns each core to a rest state if not already in that state but also inhibits the effects of the drive currents so that it is only at the trailing edge of the erase pulse that a core to which coincident drive currents are applied can be switched thereby to its opposite state. A pulse is induced in a sense wire when it changes its state from the rest state. The core may be a transfluxor.

Title: Radio direction finding system
IPC: G01S19/46
Filed: 1944-05-05
Abstract: 594,819. Radio direction-finding. MARCONI'S WIRELESS TELEGRAPH. CO., Ltd. May 5, 1944, No. 8599. Convention date, Sept. 30, 1942. [Class 40 (v)] In a "split-beam" D.F. system, the two outputs are separately modulated and then combined to provide two components proportional to the sum and difference of the two outputs, the difference component being used to vary the amplification of both components whereby the sharpness of response provided by the sum component is accentuated. The signals from the aerials 1 and 3, which have overlapping characteristics, are separately heterodyned in the mixers 7 and 9 by a common local oscillator 11. A 500 c /s modulation is applied to the mixers in phase opposition from the oscillator 13 so that the mixers are each . alternately operational for approximately one quarter of each cycle of the oscillator 13 and their outputs are combined in the variable gain I.F. amplifier 15 and then passed to the detector and audio amplifier 17. When the two outputs from the aerials are equal the two interspaced 500 c/s audio outputs combine to produce a 1,000 c /s signal, but when the two aerial outputs are unequal, one of the audio outputs is greater than the other, giving in effect a 500 c /s signal superposed on a 1,000 c /s signal. The 1,000 c/s component is separated by the high-pass filter 19 and passed through the amplifier 21 to the aural or visual indicator 23 to produce a response which is maximum when the aerials are on-course. The sharpness of the response is accentuated by separating the 500 c/s component by the low-pass filter 25 and applying it to the rectifier 27 the output of which varies the gain of the I.F. amplifier 15 in an inverse manner. As the aerial system moves off course, the ratio of the 500 c /s to the 1,000 c/s component increases and the gain of the I.F. amplifier 15 decreases producing an indication at the indicator 23 with a sharp maximum response, Fig. 2 (not shown).

Filed: 1923-03-29
Abstract: 195,961. Bischof, B., and Haccius, C. April 10, 1922, [Convention date]. Refrigerating, compression machines for.-To prevent wet refrigerant vapours from reaching the electric driving motor, the motor is housed in a chamber filled with air and communicating with the evaporator through a balancing chamber, which is either filled with oil or, alternatively, is provided with a layer of oil floating on the surface of the liquefied refrigerant contained therein. Either arrangement ensures, moreover, that the pressure and temperature of the air in the motor chamber vary with the working conditions. In Fig. 1 the motor 2, 3 is housed in the casing 1 communicating, through a pipe 6, with the balancing chamber 9 which is arranged as the centre one of three concentric chambers, the outer one of which comprises the evaporator 11. The evaporator communicates with the suction side of the compressor, not shown, through a port 13, whilst liquid refrigerant returns from the condenser 19 through a passage 10<a> and the annular chamber 10. The condenser is provided with a cooling jacket 18 and a layer of oil 17 floats on the surface of the refrigerant in the balancing chamber. When the compressor is working, diminution of pressure in the evaporator causes the refrigerant to rise therein from the level 15 to the level 16, with a corresponding lowering of the level to 17 in the balancing chamber, thereby reducing the pressure and consequently the temperature in the casing 1. In Fig. 2, the motor is housed in a chamber 42 surrounded by a second chamber 37. The balancing chamber 38, filled with oil to the level 47 when the apparatus is not working, is arranged beneath the motor and communicates by passages 42<a>, 39 with the chambers 42, 37 respectively. The condenser 23, surrounded by a cooling-jacket 23a, contains the compressor 28, an oil separator 30 and an oil chamber 46, and the evaporator 34 is arranged therebelow, with a liquid refrigerant passage 31 communicating therewith. A small tube 40 arranged in the balancing chamber 38 carries oil to the driving shaft 26.

Title: Machines for insulating armature windings
IPC: H02K15/00
Filed: 1923-04-05
Abstract: 208,969. Moore, W. E. April 5, 1923. Apparatus for making; insulation.-Strips of insulating paper or like material are cut from a sheet by a reciprocating blade which forces them into the slots of a dynamo or like armature which is turned stepby-step to receive them. The armature is placed in a recess in a block 70 and a collat in a rotating headstock 14 receives one end of the armature shaft, while the other enters a tailstock 49. The insulating material enters a guide slot in a plate 73 and is cut by a blade 5 attached to a head 4. To the head 4 is attached a bar 9 carrying an arm 36 which by means of a spring 37, pin 39, and slot 38, Fig. 6, operates an arm 28 in such a way that the arm moves at the beginning of the descent of the head 4 only and then bears on a stop 35. The arm 28 carries a pawl 29 engaging with a ratchet 21 attached to the headstock 14 and having teeth equal in number to the slots of the armature. To ensure the machine being started in the proper place a finger 84 on a shaft 82 is turned to enter one of the slots, and then withdrawn by a spring 85. To stop the machine when all the slots have been filled there is provided a lever 90, Fig. 3, drawn upwards by a spring 87 to stop the machine through a rod 86<1>. While the machine is in action the rod 86<1> is held down by a projection 97 on the lever 90 bearing on a disc 96 on the spindle 17 of the headstock. When the headstock has completed a revolution the projection 97 enters a recess in the disc 96 and allows the rod 86<1> to stop the machine. The machine can also be stopped at any time by moving the end of the lever 90, which is jointed at 95, transversely away from the disc 96 by hand against the resistance of a spring. When the slots have all been filled the tailstock 49 is slid to the right by means of a handle 47, and a set-screw on it strikes against the end of a rod 53 which strikes a rod 54 passing through the hollow spindle 17 of the headstock and knocks the armature shaft out of the collet which carries it during the slotlining process.

Filed: 1931-03-27
Abstract: 375,782. Telegraph exchange systems. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. March 27, 1931, No. 9415. Convention date, March 29, 1930. [Class 40 (iii).] Each subscriber station of a telegraph exchange system is provided with apparatus which, under the control of an initiating signal from a distant subscriber, sends a return signal, and which incorporates means for preventing the emission of the return signal if the receiving apparatus is out of order for reception. Additionally the apparatus is arranged to prevent the transmission of a return signal by the apparatus of a subscriber who has initiated the transmission of a reporting signal from the remote station with which he is connected. To initiate the reporting signal, a subscriber operates a key-lever effecting the transmission of a code combination of impulses which, at each station, operates a bar Z closing over operated contact z and released contact v, at the distant station, the energizing circuit of a magnet winding M. The core g<2> operates a ratchet wheel mechanism f, i to rotate for one revolution a shaft K carrying a cam wheel K<1> which, at contact K<4> effects the transmission of the impulses for return signal. The rate of transmission of the impulses is regulated bv a synchronizing arrangement S, S\ controlled by brushes c, c<1> associated with a commutator C on the shaft of the telegraph motor. When a subscriber operates his key T to initiate the return signal from a distant station, the slowrelease relay V energizes, and at contact v opens the circuit of the relay M to prevent the operation of the reporting apparatus at the initiating station. If the receiving tape P is torn or used up, a roller R falls into a slot L in the guide-plate F, and closes contacts pl, p<2> over which the relay V is energized to prevent the relay M from being operated when the contact z is closed by the initiating signal from the distant or calling station.
