Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T15/04
Filed: 1921-01-22
Abstract: 176,593. Peter, B. H., Peter, L. H., and Westinghouse Brake & Saxby Signal Co., Ltd. Jan. 22, 1921. Fluid-pressure; indicators, applications of. - The brake-cylinder exhaust valves of an electropneumatic brake system have two windings one of which is included in the circuit of the brakecylinder supply-valve while the other serves for the control of the exhaust valve, independently of the electric supply-valve. If the exhaust valve fails to close, the train-pipe is vented to give the usual automatic application of the brakes through an electrically actuated valve controlled by the exhaust valve. The system shown is of the kind described in Specification 162,753. The application valve 16 controls the supply to the brake cylinder 1 from the main reservoir pipe 6. and the release valve 61 controls the exhaust port of the triple valve 2 connected to the train-pipe 4 by which the usual pneumatic control can be effected. The valve 61 is provided with two windings 62, 63 of which the winding 62 is in series with the winding of the application valve so that energizing the train wire 10 opens the valve 16 and closes the valve 61. The winding 63 is connected to the train-wire 11 by which the valve 61 can be controlled for holding the brakes applied or for graduating the release. The windings 62, 63 are so wound and connected that should they accidentally become traversed by current in series, with each other, the magnetizing: effect is neutralized and the valve is not actuated. The means by which the failure of the release valve 61 effects the venting of the trainpipe 4 through the driver's valve and a valve 23 included in an interlock train-wire 12 are similar to those described in the above-mentioned Specification. In this case, however, the moving element of the release valve is provided with contacts 65, or is otherwise arranged to close the circuit of the valve 23 and train-wire 12. The application valve may be provided with contacts such as 65 included in an indication circuit for proving the operation of the application valves throughout the train.

Title: Process of treating flowable foods containing fats
IPC: A23B5/02
Filed: 1944-02-17
Abstract: 640,897. Preserving flowable foods. GOLDEN STATE CO., Ltd. Feb. 17, 1944. No. 2963. Convention date, Dec. 26, 1942. [Class 49] In order to render flowable food containing fat, e.g., milk or egg, resistant to deteriorative oxidation changes on storage after concentrating or drying, the food is subjected initially to heating under such a pressure that no gasification or boiling occurs, is thereupon heated under a pressure so much lower than the pressure during the initial heating that rapid evaporation of moisture from the food and subdivision of the solids thereof into smaller particles take place, the suspension of smaller particles and residual liquid in the vapour and gases so evaporated is then caused to move at a velocity of at least 200 ft./sec., evaporation of moisture from the particles being maintained, and finally this movement is abruptly interrupted. With the apparatus of the drawing, milk, led by a pipe 12 into a direct steam heater 13 and therefrom into a tank 16, and thereby heated in ¢-4 min. to 160‹-260‹F, preferably 230‹F, is introduced by way of a pipe 19 into a chamber 35 at the base of a cylinder 20, where the pressure is less, and the mixture of milk particles and vapour here formed passes upwards through a number of vertical tubes 32 heated by steam introduced into a chamber. 23 which surrounds the tubes and is in open communication with the cylinder 20, and emerges from the upper ends of the tubes to strike a plate 36 in a chamber 28, the milk and milk solids collecting in the chamber 28 flowing by way of a pipe 41 to a second apparatus, similar to the apparatus 20, 23, 28, comprising a cylinder 61, steam chamber 47 and impact chamber 80, and the vapour from the chamber 28 flowing by way of a pipe 44 through a liquid trap 45 to the chamber 47. The Specification as open to inspection under Sect. 91 comprises also the treatment of any oxidizable organic material by causing the material to move at a high velocity and then to impinge forcibly on a surface, thus converting the kinetic energy of the material into heat and so instantaneously volatizing certain constituents of the material. This subject-matter does not appear in the Specification as accepted.

Title: Improvement in magnetos
IPC: H02K35/06
Filed: 1926-02-02
Abstract: 271,932. Marks, E. C. R., (Wico Electric Co.). Feb. 2, 1926. Inductor machines; reciprocating machines.- A reciprocating armature magneto, particularly for ignition in high speed internal-combustion engines is provided with means for controlling the movement of the armature so as to permit. it either to contact with the fixed poles or to be held out of contact therewith, and the minimum air gap between the armature and the poles may be varied. The magneto comprises stationary magnets 10 connected to two cores 11 carrying high and low tension windings 12, 13, and an armature or inductor 14 slidably on a guide pin 35 towards and away from the fixed poles. Movement of the inductor is effected by means of a cam 41 on the driving shaft cooperating with the arm 39 of a pivoted crank, the other arm 38 of which is pivoted to the inductor. A spring 43 presses the arm 39 against the cam. The pivot stud 40 for the crank lever is eccentrically fixed on a shaft 46 which can be rotated by a handle 51 so that the degree of approach of the inductor to the poles may be varied. The shape of the cam 41 is such that the inductor accelerates rapidly after a slow initial movement. The contact breaker in circuit with the coils 13 comprises a fixed adjustable contact 17 carried by but insulated from a tube 24 fixed on the frame, and a movable contact 18 fixed to a stem 27 which passes through an abutment 28 on the inductor. An adjustable abutment 29 on the stem 27 is adapted to be engaged by the inductor abutment 28, whereby the contacts are separated against the action of a spring 31 after the armature has been moved through a predetermined distance. Alternative means for operating the contact breaker are provided by a cam 53 co-operating with a pivoted arm 58. The arm 58 is connected to a link 61 having a head 64 slidable within a sleeve 62 on the lower end of the stem 27. When the lever 58 is depressed by the cam 53, the link 61 separates the contacts. Either of the means described may operate the contact breaker, but the second is preferably employed as an additional control whereby the contacts are maintained open until the inductor is seated on its poles. The timing may be adjusted by operating the handle 51 since movement of the inductor alters the position of the abutment 28. At low speeds, the inductor preferably is arranged to contact with its poles and thus retarded ignition is obtained automatically.

Title: Improvements in or relating to relaxation oscillators
IPC: H03K4/16
Filed: 1949-02-04
Abstract: 659,425. Pulse generating circuits. PHILCO CORPORATION. Feb. 4, 1949, No. 3130. Convention date, Feb. 6, 1948. [Class 40 (vi)] The frequency stability with changes in supply voltage of a relaxation oscillator is improved by biassing the grid of the oscillator valve to a predetermined voltage which is of the same magnitude as that bias which at low anode voltages causes the oscillator to oscillate at a frequency which is the same as the frequency of oscillation with high anode voltage irrespective of the value of bias. The grid should preferably be biassed to approximately one-half of the voltage required to produce cut-off when approximately one hundred volts is applied to the anode of the valve. In a relaxation oscillator with a resistor capacitor time constant circuit which determines the repetition frequency the grid is biassed negatively and when an inductor, resistor time constant circuit is used the grid is biassed positively. Fig. 2 shows a saw-tooth generator circuit in which capacitor 28 is charged from the stabilized D.C. supply via resistor 24 and is discharged rapidly through valve 22. The amplitude of the saw-tooth output voltage is variable by adjustment of resistor 24 and the potential divider 32, 33 biasses the grid-cathode circuit to give the maximum frequency stability with changes in amplitude of the output voltage.
