Patent GB-808501-A (GB)
Title: A hydraulic metering device
Inventor: GRAY THOMAS
IPC: F15B11/13
Filed: 1955-08-04
Abstract: 808,501. Valves. HAMWORTHY ENGINEERING Ltd. Aug. 4, 1955, No. 22438/55. Class 135. Upon opening a main control valve, not shown, fluid enters an inlet 16, Fig. 1, and flows into a passage 18, past the conical end 20 of a screw 21 through a port 19, branching from the passage 18, and into the outlet 17, by way of the upper part of the valve cylinder 11, from whence it enters a power device, not shown. Some of the fluid will continue along the passage 18 and enter the cylinder 11 via a cross-bore 22, Fig. 2, and a duct 23; the opening between bore 22 and duct 23 is controlled by a needle valve 24 adjustable by means of a knob 25. The piston 12 in the cylinder 11 will therefore be raised against the action of a spring 15 until it reaches a seat 13 whereupon the outlet 17 is closed; the amount of fluid which passes into the outlet is directly dependent upon the speed of the valve 12 and hence upon the setting of the needle valve 24. The end 20 of the screw 21 produces a pressure drop in the fluid passing into the port 19 so that the fluid acting beneath the valve 12 can overcome both the force of the spring 15 and that of the fluid passing into the outlet, which acts on the top of the valve 12. When the main valve is moved into the neutral position the flow of fluid to the inlet ceases and the spring 15 returns the valve 12 to the position shown, fluid from beneath the valve being transferred via a channel 26 controlled by a non-return valve 27, passage 18 and port 19 to the top of the valve cylinder 11. Upon moving the main valve to the drain position fluid from the power device will flow through the outlet 17 and inlet 16, the position of the valve 12 being unaffected. The valve enables the power device to make a number of strokes of equal length without returning to its starting position; alternatively by moving the main valve to its drain position each time the piston 12 reaches its seat 13 the power device will return to its starting position after each stroke.

Title: A method of, and apparatus for, controlling or graduating the fineness of the products of grinding machines
IPC: B02C19/00
Filed: 1930-07-26
Abstract: 366,001. Impact pulverizers. SOC. ANON. D'OUGREE MARIHAYE, Ougreelez-Liege, Belgium. July 26, 1930, No. 22552. Convention date, Aug. 22, 1929. [Class 59.] In rotary impact pulverizing mills the ground material is delivered into a chamber in which a static pressure is maintained, this pressure being vented only for the purpose of regulating the fineness of grinding. The particles issuing from the rotary grinders encounter dense air which tends to retain them in the grinding zone for a,period which varies with the density of the air, i.e. with the static pressure. As shown diagrammatically in the Figure the invention is applied to a "Carr'' type mill having two sets 1 of grinding members. The material is fed to the grinders through shoots 2, and is discharged when ground into a chamber 4, the outlet of which is sealed by a rotary valve 6. Manometers 12, 13 indicate the air pressure and the compartment 4 is divided by a partition 9. The static pressure is built up by the centrifugal action of the grinders and is vented for fineness regulation through a relief valve 3. In a modification the sealing is effected by.the ground material itself which piles up around the exit opening and escapes gradually.

Abstract: 1,170,206. Reforming hydrocarbons. TEXACO DEVELOPMENT CORP. 13 May, 1968, No. 22575/68. Heading C5E. A method of reforming gasoline boiling range hydrocarbons and enriching the aromatic content of fractions of kerosene boiling range hydrocarbons comprises passing said gasoline boiling range hydrocarbons to the first of at least two separate catalytic reforming zones in series flow in contact with a platinum group metal reforming catalyst under catalytic reforming conditions, passing a 430‹ F. end point cut of a straight run kerosene boiling range hydrocarbon fraction to one of said catalytic reforming zones subsequent to the catalytic reforming zone to which said gasoline boiling range hydrocarbons are passed whereby partially reformed gasoline and the kerosene boiling range hydrocarbons are subjected to catalytic reforming conditions in said subsequent reforming zone, and withdrawing effluent from said subsequent reforming zone and separating therefrom a gasoline fraction and a fraction comprising naphthalene precursor feed stock. In an example, four stages of reaction are used, the gasoline boiling hydrocarbons being introduced to the first stage and the 430‹ F. end point kerosene boiling range hydrocarbons being introduced to the fourth stage. The catalyst comprises a platinum metal on alumina containing combined halogen. The feedstock is reheated between stages and is finally subjected to two stages of distillation, the first to remove butane and lighter gases and the second to separate the reformed gasoline from the naphthalene precursors.

Title: Improvements in or relating to circuits for silent tuning of radio receivers
IPC: H03G3/28
Filed: 1952-09-12
Abstract: 722,158. Radio receiving circuits; frequency mediation. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Sept. 12, 1952 [Sept. 17, 1951], No. 22954/52. Class 40 (5). A rectifier whose load comprises a bridge network provides a muting bias and also delayed automatic volume control (A.V.C.). In a frequency-modulation receiver an LF. stage 2 feeds a discriminator comprising a nonode 4, this valve being cut off in the absence of signals by means of a positive bias applied to its cathode over resistance 6. To remove the muting a positive bias, derived from a network 9, is applied to the inner grid of valve 4. The network 9 comprises a rectifier 7 fed with I.F. over condensers 10, 13 and having as load a bridge network of resistances, the arms of the bridge being AB, BC, CD and DA respectively. An.A.V.C. voltage is derived from the point D, while the inner grid of the valve 4 is connected to a tapping point E in the arm DA and to a smoothing condenser 14. The bridge is balanced in the absence of signals and remains balanced as the signal and the output of rectifier 7 increase, until the point E becomes sufficiently positive to drive the inner grid of valve 4 into grid current. The valve 4 is then operative and the point E " clamped " at a fixed potential by the grid current: the bridge balance is thus destroyed, so that further increase in signal level causes the potential of the point D to move increasingly negative. In a modification, a point on one of the' arms of the bridge is connected via a biased rectifier to a point of constant potential, so that the A.V.C. potential arises at the point D when the threshold of the rectifier is passed. In order to suppress amplitude modulation by-pass condensers 13, 11 are provided across AB, DF, any amplitude modulation being fed into the A.V.C. line so as to vary the gain in opposing sense.
