Title: A method of increasing frequency by means of static transformers
IPC: H03B19/03
Filed: 1921-10-29
Abstract: 192,461. Jones, H. Sefton-, (Lorenz Akt.- Ges., C.). Oct. 29, 1921. Frequency, changing.-In an arrangement for multiplying the frequency of an alternating current by the aid of static frequency transformers, the winding w<1> of a transformer t with a closed magnetic circuit adapted to become highly saturated is connected to the source g of alternating current through a circuit which includes an inductance s of a value considerably greater than the inductance of the transformer, this circuit being tuned to the frequency of the source. An oscillatory circuit c<1>, s<1> tuned to an even or odd harmonic of the frequency of the source is placed in parallel with the winding w<1>, permanent directcurrent magnetization of the core of the transformer being employed when an even harmonic is desired. The high initial inductance of the transformer may be overcome by temporary direct.current magnetization of its core or by short-circuiting part of its winding, the direct-current excitation or the short-circuit being cut out when resonance is reached. The source, g of alternating current may be a high-frequency alternator or a Poulsen generator. When the arrangement is employed for the purposes of wireless telegraphy or telephony, the antenna, may be connected either directly to the whole or a part of the winding w' or to a separate secondary winding of the transformer. An inductance variable under the action of microphone currents may be included in the oscillatory circuit c<1>, s'.

Patent GB-677699-A (GB)
Title: Process for the manufacture of monoalkylpiperazines
Filed: 1950-11-27
Abstract: N-monoalkyl piperazines are made by hydrogenating polyalkylene piperazines formed by reaction between piperazine and an alkyl aldehyde.  Reduction may be effected at ordinary or elevated temperatures.  Conventional methods of hydrogenation are used and are specified.  Small amounts of piperazine and N,N1-dialkyl piperazine are also obtained and the monoalkyl piperazine is isolated therefrom by treatment with carbon disulphide which forms addition compounds with the substances which still have an imino group.  The addition compounds are separated and hydrolysed with hydrochloric acid to give the dihydrochlorides of the monoalkyl piperazine and piperazine which may be separated because the former is soluble in boiling methanol whilst the latter is only sparingly soluble in this solvent.  When only small quantities of dialkyl product are present isolation of the monoalkyl compound may be effected without carbon disulphide treatment by using the solubility differences in boiling methanol of the dihydrochlorides of the remaining substances.  The base may be liberated from the dihydrochloride by usual methods, e.g. by the use of lime, concentrated solutions of alkalies or with an alcoholate of an alkali metal.  The monoalkyl piperazine may also be isolated by steam distillation from a strong alkali solution.  In examples: N-monomethyl piperazine is obtained from polymethylene piperazine (which may be prepared in situ), hydrogenation being effected by means of hydrogen and Raney nickel in a variety of solvents, hydrogen and copper chromite, zinc and hydrochloric acid, and formic acid in toluene, the isolation of the product being effected as above described.

Title: Improvements in methods of and apparatus for indicating or/and recording the dewpoint of vapour-containing gaseous fluid
Inventor: JENNINGS ALFRED PETER HENRY
IPC: G01N27/22
Filed: 1956-09-25
Abstract: 856,116. Electric - measuring systems. BAILEY METERS & CONTROLS Ltd. Sept. 25, 1957 [Sept. 25, 1956], No. 29284/56. Class 40 (1). Apparatus for determining the relative humidity of a gas comprises a condenser with a porous dielectric exposed to a sample of the gas, so that its capacitance is determined by the humidity, whose temperature is adjusted to produce a predetermined value of humidity by comparing the capacitance of the condenser with a value representing the predetermined value of humidity, any difference being used to control the temperature, which is measured by a thermocouple and indicates the relative humidity of the gas. Construction (Fig. 1).-The gas to be tested flows through a vessel 1 whose base consists of a copper disc 6 covered by an aluminium disc 8, the upper surface being anodized to form a thin, porous layer 9, which is itself covered by a thin coat 10 of colloidal graphite or metal deposit, thus forming a humiditysensitive condenser. A heating element 17 is embedded in the surface of the copper disc, and a copper rod 12 attached to the disc 6 and dipping into a vacuum flask 13 containing a volatile liquid 14 constitutes a cooling system for the condenser. The temperature is measured by a thermocouple 21 in contact with the external coating 10. Circuitry (Fig. 2).-The test condenser 11 is incorporated in a bridge 25 and compared with a fixed condenser 29, the bridge unbalance current being fed to a relay 32 which closes the heating circuit for element 17 when the measured humidity is too high. Thus intermittent heating and continuous cooling of the condenser occurs to maintain the average temperature and relative humidity at the value which causes condensers 11 and 29 to have the same capacitance. In one modification, relay 32 controls a servomotor adjusting a rheostat in the heating circuit. In another modification the cooling is effected from the cool outlet of a Hilsch tube by adjustment of the throttle in the warm outlet of the tube.

Title: Method for forming an interconnection through an insulating layer
IPC: H05K3/40
Filed: 1971-06-22
Abstract: 1326129 Printed circuits INTERNATIONAL BUSINESS MACHINES CORP 22 June 1971 [4 Sept 1970] 29322/71 Heading H1B A method for forming an interconnection in an electrically insulating layer 12, 13 separating two conductive layers 10, 11 is characterized by the fact that the insulating layer is of photosensitive material. In one embodiment two separate laminates 12, 10 and 13, 11 of photosensitive and conductive material are irradiated through masks (15), (Fig. 1b, not shown) to produce soluble and insoluble portions of photosensitive material, the soluble portions defining the opening. The photo-resist used in the present embodiment is of the more common negative type, insolubilizing upon exposure to irradiation. After irradiation the laminates are combined as shown to form a thicker laminate. The top conductive layer is then covered with photo-resist 20 which is exposed through mask 15 defining the region of the opening. The photoresist is developed, the soluble portion of which defining the region of the opening is removed. An etching process is then used to remove the metal in the region of the opening (Fig. 1e, not shown). The soluble portions 18, 19 of the insulating layer can then be removed by solvents and the opening metallized (Figs. 1f and 1g, not shown). Resist layer 20 is then removed, conductive layers 10, 11 then being clear for formation of the circuit lines. To improve adhesion between the laminates a modified process is utilized (Fig. 3, not shown). In this embodiment a mask (42) exposes only an annular region (45), around the opening region (44), to the irradiation. In this way most of the photo-sensitive layer remains unpolymerized or soluble and has better adhering characteristics when joined to the second laminate. In a further embodiment (Figs. 2a-2c, not shown) a positive type photo-sensitive layer is attached to only one conductive layer, irradiated, the second conductive layer added and etched, and the soluble portion of the photo-sensitive layer removed. In an alternative embodiment, the positive type of photo-resist is used, i.e. one which solubilizes upon irradiation, and results in a modified process (Figs. 5a to 5b, not shown). The irradiation of the insulating layers now takes place through different masking arrangements and after the laminates have been joined. The second conductive layer may also be etched in the region of the gearing (Fig. 6, not shown). The photo-sensitive layer in all the embodiments may be reinforced, e.g. with fibrous material, generally glass fibres (55) (Fig. 4, not shown).
