Title: Process of rapidly and uniformly breaking up the cellulosic constituents in vegetable substance, for the production of manure
IPC: C05F15/00
Filed: 1926-01-21
Abstract: 258,149. Fõkaltorf-Studien Ges., and Crusius, A. Baumgarsen-. Jan. 21, 1926. Manures.-The cellulosic constituents of vegetable materials are broken up by treatment with a mixed culture of aerobic and anaerobic microorganisms, adapted to ferment cellulose and obtained from farm soil, horse manure, garden and leaf mould, and forest soil. These materials are heated to 60‹ C. to destroy undesired bacteria, and separate portions of the different materials are then exposed as loose layers to air at a temperature of 50‹ C. while other portions are heated to 50‹ C. under anaerobic conditions. The two cultures, aerobic and anaerobic, so obtained are lixiviated with a single colloidal peat solution containing small quantities of ammonium sulphate and sugar, and this solution is added to sterilized matter of the class from which the cultures have been obtained. The several batches of material so inoculated are mixed together and the mixture, after fermentation, is added to a mixture of farm soil, horse manure, beech leaves and peat. This mixture after further fermentation is added to the vegetable material which is to be decomposed. In an example, it is added to a mixture of peat, faecal matter and Thomas slag.

Patent GB-813035-A (GB)
Title: Improvements in or relating to pressure regulating valve systems
IPC: G05D16/16
Filed: 1956-01-24
Abstract: 813,035. Fluid-pressure servomotor control systems; valves. BENDIX AVIATION CORPORATION. Jan. 24, 1956 [Jan. 28, 1955], No. 2360/56. Class 135.  A valve system for controlling the pressure in a discharge line with respect to atmospheric pressure independently of the pressure variations in a supply line. The supply line 10, Fig. 5, leads to a chamber 13 connected to a discharge chamber 14 via a port 86 controlled by a balanced disc valve 80. The discharge chamber has an outlet 15 to the discharge line. The closure member 80 is actuated by a rod 87 controlled by a diaphragm 77 subject on one side to the discharge pressure in the chamber 14 and on the other side to a reference pressure in a chamber 75 which reference pressure is obtained as hereinafter described. Passages 18, 40 lead from the line 10 to a chamber 42 via a shut-off solenoid controlled needle valve 24, 28, 32. The chamber 42 is connected to a regulating chamber 55 via a port 53 controlled by a balanced disc pilot valve 47 actuated by a rod 57 controlled by a diaphragm 59 the loading spring 63 of which is adjustably located within a chamber 61 open to the atmosphere at 62. The chamber 55 is connected to the atmosphere by a bleed orifice 65. With the solenoid 32 energized the needle valve 24 is in its open position so that the diaphragm 59 is subject on one side to atmospheric pressure in the chamber 61 and to the pressure of the loading spring 63 and on the other side to the pressure in the chamber 55 which is so regulated by the valve 47 as to be maintained at a reference pressure a predetermined value above atmospheric pressure. The chamber 55 is connected to the chamber 75 so as to apply the reference pressure to the upper side of the diaphragm 77. The main valve closure member 80 is urged to its closed position by a spring 83 so that the pressure in the chamber 14 and in the discharge line 15 is regulated to a value a predetermined differential below the reference pressure in the chamber 75, the actual value being determined by the prevalent atmospheric pressure. With the solenoid 32 de-energized deliberately or accidently the needle valve 24 assumes its closed position and the bleed orifice 65 allows the pressure in the chamber 55 to decay to atmospheric pressure. The pressure in chamber 75 is thus reduced to atmospheric pressure and the spring 83 moves the closure member 80 to its closed position against the seat 85. Upon failure of the diaphragm 77 the spring 83 closes the valve 80 even if the needle valve 24 is open. Specifications 813,034 and 813,036, [both in Group XXXIII], are referred to.

Abstract: 361,191. Gas meters. PINTSCHAKT.- GES., J., 71, Andreasstrasse, Berlin. Jan. 26, 1931, No. 2577. Convention date, March 4, 1930. [Claes 54.] In a gas meter in which the counter mechanism is operated in proportion to the distance traversed by the diaphragm, provision is made for increasing the transmission ratio of the movement of the counter-mechanism when the diaphragm is at the ends of its travel so as to correct the indication when the consumption is high. In the meter shown in Fig. 1 the counting mechanism 7 is operated by rods 6 carried by one end of a lever 5, the other end of the lever carrying an arm 9 projecting between two stops 10, 11 carried by a lever 3 oscillated by the diaphragm 1. At the ends of the diaphragm travel the lever 9 is engaged by one of two stops 12, 13 on an extension of the lever 3 and, owing to the shorter leverage, the ratio of the movement of the counting mechanism to the movement of the diaphragm is increased. The stops 12, 13 may be adjustably mounted so as to allow the amount of correction to be varied. In the meter shown in Fig. 2 the lever 5 has an idle movement at the commencement of each operation of the rod 6 operating the counting mechanism. This idle movement may be adjusted by means of a screw 17. Alternatively the idle movement may be provided by spacing the stops 10, 11 which may be adjustably mounted in the diaphragm. The idle movement may be employed for lifting the pawls on the operating shaft of the counting mechanism.

Abstract: 782,566. Automatic temperature control systems. NATIONAL RESEARCH DEVELOP MENT CORPORATION. Jan. 27, 1955 [Jan. 29, 1954], No. 2705/54. Class 38 (4). To maintain constant the temperature of a metal cylinder T2 which forms the closed secondary of a transformer T supplied from an A.C. source, contacts A1 of a relay A are opened to de-energize transformer T whenever the current in a resistor R1 falls below a predetermined value. This current is representative of cylin. der temperature since the resistance of the cylinder material increases with temperature, and controls relay A through valves V1 and V2. Contacts A2 of relay A introduce a condenser C2 to change the bias of valve V2 temporarily to ensure that each de-energization of transformer T persists for a predetermined minimum period. Contacts A3 of relay A reduce the bias of valve V1 when the voltage across resistor R1 disappears on de-energization of transformer T. In a modification, the minimum period of de-energization is made to vary inversely with the period of energization by arranging condenser C2 to be slowly charging during the energization period. Cylinder T2 may be a drying cylinder in photographic film recording and developing apparatus.
