Abstract: 565,422. Transmitting mechanical power. ENGLISH ELECTRIC CO., Ltd., CARNEGIE, H. S., and WELSH, R. J. June 7, 1943, No. 9096. Addition to 528,404. [Class 38 (iv)] [Also in Group XXXVII] In electric power equipment as described in the parent Specification, comprising independently driven main alternators 1, 2 supplying in parallel a load 3, such as a ship propulsion motor, and wherein low voltage auxiliary alternators 6, 7 connected in series with and mechanically coupled to the main alternators maintain synchronism of these machines when it is desired to reduce to zero the voltage across the load, this voltage reduction is effected by means for modifying the excitation of the main alternators so that they generate an E.M.F. substantially equal and opposite to that of the auxiliary machines. The excitation arrangements may be as shown in connection with the machine 1, wherein either a main field excitation winding 1a or a weak oppositely acting auxiliary winding 1b may be selected by a switch 8. Alternatively, as shown for the machine 2, a single exciting winding 2a may be tapped across a potentiometer 9 and provided with a reversing switch 8. The auxiliary alternators preferably assist the main machines and, if of greater output than is necessary for synchronising purposes, may supply an auxiliary load through transformers 15, 16 connected to the synchronising bus-bars.

Title: Improvements in or relating to high frequency electron discharge systems
IPC: H01J25/52
Filed: 1942-07-06
Abstract: 578,655. Magnetrons. WESTERN ELECTRIC CO., Inc. July 6, 1942, No. 9309. Convention date, July 19, 1941. [Class 39 (i)] An electron beam is projected into the oscillation space within the anodes from one end and means are provided to densitymodulate the beam at the oscillation frequency in such phase that electrons enter the oscillation space only at times when they give up energy to the oscillatory electric field. The modulation may result from the bunching of an initially velocity-modulated beam. The tuned circuits connected to the output anodes and the modulation means may be Lecher wires or hollow resonators. In one form, the electron beam from cathode 1, Fig. 2, is focused by interleaved lens electrodes 21, 22, velocity-modulated by grids 23, 24 and enters the space between split anodes 2, 3. After giving up energy to the field, the electrons pass to collector 20. A coil 5 provides the axial magnetic field. Anodes 2, 3 are back coupled to grids 23, 24 to cause selfoscillation in a single Lecher system 9, 10, 11 ; for amplification separate systems may be connected to the grids and anodes. In another form, the anode 42, Fig. 5, is a complete cylinder surrounding a diverging electrode 41. Electrodes 41, 42 are connected to the inner and outer members 43, 44, respectively of a coaxial line resonant chamber. The electron beam from cathode 1 is Class C density-modulated by apertured disc 48, a further coaxial line resonator 65, 66 being connected between these electrodes. The distance between the cathode and grid is chosen to eliminate transittime loading of the input circuit. The accelerating electrode 47 has a capacity flange 46. In addition to input line 70, there may be a feedback line 72 with an insulated joint 73. In a modification, the input resonator maybe connected between two velocity-modulating electrodes : an interleaved electron lens is interposed between these electrodes and the cathode, and a drift space is provided. In Fig. 7, the anode consists of four interleaved segments 94, 95, connected alternately to opposite ends of a resonator 97.

Filed: 1929-03-22
Abstract: 325,726. Dicker, S. G. S., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). March 22, 1929. Systems depending on static transformers.-X- ray apparatus is fitted with a device for increasing the intensity of the rays, by means of which the voltage at the primary terminals of the transformer is caused to exceed the voltage of the source of supply during the half cycles in which the discharge curnent flows. The primary of the transformer 2 is connected to a switch 6 and when this is in the left-hand position, directly to the source of alternating current. When the switch is moved to the right-hand position the transformer is connected by the switch 10 to one of the tappings of an autotransformer 9, which receives its current from the source through an impedance 11. In parallel with the auto-transformer is a rectifier 12, which may be a gas-filled hot-cathode discharge tube, and a steadying resistance 13. The cathode of the rectifier is heated from an auxiliary winding 14 of the transformer 9. A switch 7 and resistance 8 serve to heat the cathode of the X-ray tube, X-rays being generated only when. the switch 7 is in the position marked b. In use, an arm moving over a dial moves the switch 7 to the position a. On pressing a button, the switch is moved to b and at the same time the arm is moved back to zero by clockwork breaking the circuit after a time depending on the setting of the arm. The apparatus is contained in a casing of sheet iron and connected to the transformer 2 by a plug contact.

Title: Improvements in or relating to the manufacture of milk products
IPC: A23C9/127
Filed: 1934-03-28
Abstract: A milk preparation more particularly for use in baking is obtained by treating skimmed or other milk freed from bacteria by pasteurizing, &c., with peptone bacteria incapable of producing lactic acid, such as m. casei liquefaciens or s. liquefaciens and then subjecting it to lactic acid fermentation by lactic-acid producing bacteria such as b. acidophilus or b. caucasicus, the lactic fermentation being prevented from detrimentally influencing the peptonization by limiting the milk sugar content of the milk. The milk sugar may be removed prior to the lactic fermentation by separating the whey from the albuminous substances by treating with acid, rennet, &c., so that the total amount removed in the whey and decomposed in the subsequent lactic fermentation does not exceed 70 per cent of the total milk sugar content. Alternatively, yeasts, such as lacto-yeast, may be added to decompose the milk sugar, preferably in such a way that acidity of the end product does not substantially exceed 80-100 DEG Soxhlet-Henkel and the total decomposition of the milk sugar does not exceed 70 per cent of the total content thereof.  The product may finally be dried in atomizing or cylindrical vacuum driers &c., or used in the form in which it is obtained.  It may replace a part, e.g. 10 per cent or more, of the flour in baking and may be added to chocolates, fruit masses, &c.
