Title: Improvements in jugs, teapots, coffee pots, and the like pouring vessels
IPC: A47G19/14
Filed: 1922-12-05
Abstract: 208,364. Barratt, W. G. Dec. 5, 1922. Jugs.-A jug or like pouring vessel has a non- projecting handle b, Fig. 3, shaped to be of the same configuration as the body at the opposite side of the vessel, and has the edge a<4> of the mouth curved outwardly to form a pouring lip. The vessel may have a perforated shelf d for retaining tea leaves or coffee grounds, or may have an infuser, as shown in dotted lines, and is then provided with a lid e, Fig. 9, adapted to seat on the internally-projecting flange c. In the form shown in Fig. 7, the part c<3> of this flange is at a lower level than the remainder, and its edges engage slots in, and hold in place, a detachable infuser f. Reference has been directed by the Comptroller to Specification 9438/89.

Title: 8-methyl-4-androsten-3-ones and their preparation
Inventor: NAGATA WATARU
IPC: C07J75/00
Filed: 1963-08-21
Abstract: The invention comprises 8 - methyl - 4-androsten-3-one having the formula <FORM:0985638/C2/1> wherein A is methylene, b -hydroxymethylene or carbonyl and A1 is b -hydroxymethylene or carbonyl.  These compounds are obtained by oxidizing 3,3,17,17-bisethylenedioxy-8-methyl-5-androsten-11b -ol to form the 11-keto compound, reducing the 11-keto compound to obtain 3,3,17,17-bisethylenedioxy-8-methyl-5-androsten, deketalizing the latter to obtain 8-methyl - 4 - androsten - 3,17 - dione, treating the latter with an etherifying agent to form a 3 - alkoxy - 8 - methyl - 3,5 - androstadien - 17-one, reducing the latter to form a 3-alkoxy-8-methyl-3,5-androstadien-17b -ol and hydrolysing this compound with an acid.  The starting 3,3,17,17 - bisethylene - dioxy - 8 - methyl - 5-androsten-11b -ol is obtained by oxidizing 9a -bromo - 11b  - hydroxy - 4 - androstene - 3,17-dione to obtain the corresponding 11-keto compound, eliminating HBr to form a D 8(9) compound, protecting the 3 and 17-keto groups by ketalation, hydrocyanating across the 8(9) double bond to form an 8-CN compound, reducing the 11-keto group to an 11b -hydroxy group, forming an 11(8) lactone bearing an imino group, acetylating this imino group, reductively splitting the 11(8) lactone ring to form an 8-azo-methine which is reduced to obtain the desired 8-methyl compound.

Title: Improvements in and relating to electrical regulators
IPC: H02P9/24
Filed: 1930-11-05
Abstract: 362,613. Automatic regulators. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Winter, F. H.; 43, Linden Street, Schenectady, New York, U.S.A.) Nov. 5, 1930, No. 33291. Convention date, Nov. 9, 1929. [Class 38 (iv).] A regulator which can maintain any desired power factor in a polyphase system 1 comprises a potential coil 18 energized from the system and two current coils 19, 20 each energized from a different phase. The relation between the magnitudes of the currents in these two coils may be so adjusted by impedances 24 that their resultant flux is in quadrature with that due to the voltage coil. The force due to all coils then balances the core 16 at the desired power factor. Variation of power factor causes the core to move and effect suitable variation of the excitation of a synchronous condenser 5 by its action on the Tirrill regulator contacts shown, for example, or upon any other type of regulator. Changes in current and in voltage in the system are prevented from affecting the power factor regulation by providing current coils 22, 23 operative on the mechanism in the same senses as the respective coils 18, 19 and a voltage coil 21 operating in an opposing sense on the mechanism.

Abstract: 154,228. Saunier, H. R. Aug. 19, 1919. [Convention date]. Packing surgical dressings; unpacking. - Relates to a package for aseptically treated products, such as cotton bandage, &c. The sheet of cotton a, Fig. 1, is rolled up in a sheet of paper b having secured to one end a strip d of heavy paper or cloth. A paper disk or washer f is secured to the middle of the strip d by a metal eyelet g, and a cord h attached to the eyelet serves for securing the roll. The package or roll thus formed is inserted in a bag or wrapper formed with a bellows fold i, Fig. 5, secured by a paper strip k having a tearing string l. Thus by pulling the string, the strip k is torn and the expansion of the fold enables the roll to be removed easily from the wrapper.

Title: Actuating means for internal shoe drum brakes
Inventor: HARRISON ANTHONY WILLIAM

Abstract: 925,593. Internal shoe-drum brakes. GIRLING Ltd. Jan. 20, 1960 [Oct. 21, 1958], No. 33577/58. Class 103 (1). In an actuating means for brake shoes of internal shoe drum brakes of the type in which two arcuate shoes co-operating with a rotatable drum are mounted to rock or slide at one end on a stationary anchorage on the brake backplate 11 and are adapted to be separated at the other end by an hydraulic brake cylinder 10 with which is associated a lever 19 for separating the shoes mechanically for parking, the lever 19 is mounted for rocking or pivotal movement about a fulcrum formed by nose 29 on the lever abutting hardened block 22 in a recess in the cylinder 10 situated on that side of the cylinder remote from the brake backplate 11 and an intermediate part of the lever engages through transverse pin 23 with a free piston 16 coaxial with the working piston 14 and co-operating with one of the brake shoes 17, the outer end of the lever 19 extending through an opening in the brake back-plate for connecting to a vehicle hand brake lever through suitable rigging 25, 26. The lever therefore acts as of the second order. When the brake is applied mechanically, the lever 19 is moved angularly about its fulcrum and advances the free piston 16 to apply one brake shoe, the working piston 14 remaining stationary, and the reaction on the fulcrum 22 moves the cylinder assembly in the opposite direction to apply the other shoe. The brake may be applied hydraulically through fluid connection 28. In an alternative construction (not illustrated) the free piston 16 is omitted and the actuating lever 19 engages the web 17 of the shoe directly.

Title: Improvements in and relating to electric protective relays
IPC: F23D23/00
Filed: 1932-11-30
Abstract: 411,119. Protective cut-out arrangements. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) Nov. 30, 1932, No. 33926. Convention date, Nov. 30, 1931. [Class 38 (v).] A protective relay arrangement responsive to reversal of the flow of power in a protected network and operative in accordance with the phase relationship of two electrical magnitudes for example current and voltage in that circuit has a potential proportional to one of such magnitudes applied to the grid of a vapour electric discharge device and the anode energized by a potential proportional to the second magnitude, one of the potentials being displaced in phase in relation to the corresponding network magnitude by such an angle that an angular variation of the network magnitudes beyond a definite amount produces an abrupt variation of the anode current. As shown in Fig. 5 an earth-faultresponsive arrangement has a vapour electric discharge device 10 the plate 8 of which is energized by a potential corresponding to the earth leakage potential, and the grid by a potential corresponding to the earth leakage current. The former potential is supplied from the network 1, 2, 3 through a coil 5 of a potential transformer 4, the latter potential is supplied through paralleled series transformers 15 and a transformer 13 the secondary 12 of which is connected between the grid 11 and cathode 9. A condenser 24 and resistance 25 are also connected across this circuit in order that the potential of the grid 11 lags behind the potential of the anode circuit by 90‹ when the current in the primary winding 14 of transformer 13 is in phase with the potential at the winding 5. This phase angle may be adjusted by a variable resistance 16. Thus a sudden alteration in the anode current of the vapour discharge device takes place when the earth current leads the earth voltage by more than 90‹ and a corresponding variation of current in a circuit breaker, releasing coil 7 in the anode circuit takes place. Adjustment of the resistance 16 may, however, vary the phase conditions at which release of the circuitbreaker is effected.
