Title: Hormone preparations
IPC: A61K9/06
Filed: 1955-06-23
Abstract: Testosterone esters for use in pharmaceutical hormone preparations (see Group VI) may be produced by conventional methods.  For example, testosterone undecylenate is prepared by reacting testosterone with undecylenyl chloride in anhydrous benzene in the presence of anhydrous pyridine.  Other esters specified are the valerate and propionate.ALSO:A mixture of testosterone undecylenate, testosterone valerate and testosterone propionate is used in hormone preparations such as solutions (especially oil solutions) for parenteral administration, suspensions, emulsions, implantates, tablets, dragees, salves and creams.  Specified carrier materials include vegetable oils, benzyl alcohol, polyethylene glycols, gelatine, lactose, starch, magnesium stearate, talc, petroleum jelly and cholesterol.  Additional additives include preserving, stabilizing, wetting or emulsifying agents, buffer substances, local anaesthetics and substances having an effect on the blood vessels.  Examples are given of a preparation in sesame oil, a preparation in crystal form and of a tablet.

Title: Improvements in or relating to rectifying systems
IPC: H02M7/40
Filed: 1933-06-28
Abstract: 425,033. Converting. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin) June 28, 1933, No. 18411. Convention date, June 28, 1932. [Class 38 (ii)] In order to prevent back ignition in a rectifying arrangement comprising vapour or gas discharge vessels G1, G2 and synchronouslyoperated switches K1, K2, spark gaps F1, F2 are connected in series with resistances R1, R2 across the separate discharge vessels. The resistances have a current voltage characteristic such that they practically convey no current before reaching a critical voltage, and above this voltage their resistance falls so that they readily conduct current. They may be of the type described in Specification 404,611. The discharge vessels G1, G2 are supplied through inductances S1, S2 from a transformer W. In the case of disturbances, if the back ignition voltage rises to the critical value determined by the resistance, the spark gap breaks down and prevents the flow of current in the reverse direction through the rectifier.

Title: Improvements relating to the power factor control of electric systems
IPC: H02J3/18
Filed: 1926-07-24
Abstract: 256,600. British Thomson-Houston Co., Ltd., (Assignees of Alexanderson, E. F. W.). Aug. 5, 1925, [Convention date]. Systems depending on static transformers; phase modifying apparatus. -The power factor of an alternating current system 1, 2, 3 is controlled by electron discharge devices 10, which are equivalent to inductive or capacity reactance owing to the manner in which the grids are energized. One bank of discharge devices have their anodes connected to the middle of an interphase winding 7 connected to the star points of a double Y-connected transformer secondary 6, the terminals of the Y being connected to the cathodes and the primary 4 being star-connected to the system 1, 2, 3. A second bank of discharge devices is similarly connected to the transformer secondary 8 the primary 5 of which is delta connected to the system 1. 2, 3. The grids are normally supplied with a negative potential from a direct .current generator 28 but during part of the cycle the grid is made positive by connection to a generator 29 through a synchronously driven commutator 30, and thereby causes an anode current to flow. The brushes on the commutator are adjustable by means of a handle 36 so that the phase of the anode current in relation to the anode potential can be adjusted.

Title: Automatic antenna coupler
IPC: H03H7/40
Filed: 1957-06-12
Abstract: 815,562. Automatic control systems for matching networks; inductors. COLLINS RADIO CO. June 12, 1957 [Nov. 19, 1956], No. 18588/57. Classes 38 (2) and 38 (4). [Also in Group XL (c)] An aerial tuning unit comprises an impedance-matching network having input and output lines and variable coupling means. The coupling means comprises inductor 19, Fig. 2, with variable taps 32, 27. The input line 21 is supplied by tunable signal source 23 and along its length the phase and loading conditions are monitored by the discriminators 24, 30. Mismatch on the line operates servomotors 26 and/or 31 to vary the total inductance and/or that part of it which terminates the input line. When either tap 27 or tap 32 is in the position of maximum inductance the limit switches 28 or 33 are closed and actuator motor 34 is energized, whereby switches 35, 36, 37 are operated to place capacitor 20 in series with the aerial load and the capacitor is varied from maximum to minimum in the search for the matched condition. At minimum capacity the motor 34 is reversed by switches 38, 39, the capacitor is re-connected in parallel with the output circuit by switches 35, 36, 37 its value being varied from minimum to maximum capacity, thus completing the range of impedance variation available. When a new operating frequency is selected by circuit 45, the Auto Homing Marking circuit 46 in conjunction with circuits 47, 48, 49 resets the inductor taps, the capacitor and the actuator servo switches to the positions shown ready for a new monitoring and control sequence to be performed in the line and matching network. In one embodiment of the tapped inductor, the main winding 50, Fig. 4, is wound on a ferrite core between two clamping discs 59, 60. One of the variable taps comprises two fingers 53, 54 which bridge adjacent turns and are held in each position by detent mechanism 79-82. For fine adjustment between the spaced turns of winding 50 the sliders 53, 54 are connected to a trimming winding 51 mounted on the same axis as the main winding. Winding 51 is traversed by slider 52 which, at the extremities of the winding, causes limit pins 75, 76 or 75, 77 to engage and drive round the main winding sliders. The assembly on which slider 52 is mounted is driven by motor 87 through gearing 86. A similar mechanism is mounted on the other side of winding 50 to provide a second tap. In another embodiment the winding comprises a metal ribbon 99, Fig. 5, wound in a helical groove on an insulating former 98 and on another former 97 which is conducting so that the turns wound thereon are short-circuited. Rotation of the two formers is by gearing from motor 110 which corresponds to motor 26 of Fig. 2. The other tap is effected by slider 112 mounted on the carriage 100 which rides on the helix by rollers 116. The drive is from motor 126 to splined gear wheel 120 which meshes with ring gear 113 on the carriage. Limit switches 133, 134 correspond to switches 28 and 33 of Fig. 2.

In a pneumatic vibrator comprising a body expansible by supplying compressed air to its interior under the control of a flutter valve 44 adapted to open after predetermined expansion of the body, release the pressure in and permit collapse of the body so that continuous supply of compressed air to the body results in alternate expansion and contraction of the body, the body comprises a diaphragm 11 sealed at its periphery to a base-plate 10 and a vibrator plate 19, 20 carried by the diaphragm, the flutter valve being in the form of a double acting valve permitting compressed air to flow into the space 14 between the diaphragm and the base-plate for expanding the body and to shut-off the supply of compressed air to such space during collapse of the body. As shown a transmission plate 21, 23 is connected to the vibrator plate by way of spacers 25, the transmission plate being connected also to a centralizing membrane 27 mounted in a casing connected to the base-plate. In a modification not shown a valve is mounted on any convenient stationary part of the apparatus and in view of this it will be necessary for the registering plate to be mounted so as to vibrate in unison with the vibrator plates. A single flutter valve is employed as a common valve controlling a plurality of expansible bodies. Specification 1,119, 660 is referred to.

Spring- pressed levers 18 carried by the arm bear on the fixed pins 17 to assist the movement of the arm into indicating position. Movement is limited by stop 10 engaging members 11 on the casing c. The arm may comprise metal edges p, p<1> holding celluloid panels q, or the arm may be moulded. A lamp w is carried by a spring clip in the plug y, the lamp being withdrawn when the plug is screwed out. The detent 12 may be provided with a manual release to enable the arm to be swung out by hand.
