Title: Improvements in charge treating devices for internal-combustion engines
IPC: F02M1/10
Filed: 1931-03-25
Abstract: 372,045. Treating charge. ALBERT, K., 9, Herderstrasse, D³sseldorf, Germany. March 25, 1931, No. 9137. Convention date, March 25, 1930. [Classes 7 (ii) and 7 (iii).] The whole, or the larger part, of the air for combustion, after being heated, is humidified to a predetermined degree under the control of a hygrostat or a thermo-regulator. As shown in Fig. 1, heated air enters at e a chamber a containing porous rings d. A hygrostat g actuates a valve h which admits warm water from the engine radiator R to the chamber a to maintain the humidity of the air constant. The water is kept at a constant level in the radiator R by a pump l which forces the water through a control valve m partly to the radiator R and partly through a pipe n into a supply tank T. In a modified construction, Fig. 2, a thermo-regulator g<1> operates a valve o, which maintains the temperature of the heated air entering at e constant by adding cold air, and the water valve h. The water is supplied in excess of the amount needed to saturate the air, the excess being removed by a pipe q. To prevent condensation of water in the induction pipe from the saturated air, cold air is added through a byepass s controlled by a valve r. Crank case fumes may be added to the top of the chamber a. In a further modification, the intake air is kept at a constant temperature by passing it through a heat exchanger where it extracts heat from a thermo-regulated water system. The heated air is then saturated with water.

Title: Improvements in or relating to instrument suspension systems
IPC: G01R11/02
Filed: 1941-07-25
Abstract: 580,680. Measuring gravitational forces. CAMBRIDGE INSTRUMENT CO., Ltd., and MARSH, M. C. July 25, 1941, No. 9471. [Class 97 (iii)] [Also in Group XXXVI] The torque due to an instrument suspension system is reduced by electrostatic means. The invention may be applied to geo-physical instruments for measuring gravitational fields, but is shown applied to a fluxmeter of the totally suspended Grassot type. A movable plate a is fixed to the pointer b and maintained at earth potential, the moving coil and mirror c being hung from a silk thread d and current being led to the coil by ligaments. Two fixed metal plates e are disposed radially and symmetrically on either' side of the movable plate a, the distance separating the movable from the fixed plates being large compared with the maximum movement of the plate a. The plates e are insulated from earth, but connected by a part f and are connected by a wire g to a source of A.C. or D.C. voltage. The plates e are supported by a wire h having a portion which runs parallel with the pointer b. When this wire is charged the pointer is brought rapidly back to zero. The position of the wire h and consequently the zero position of the pointer is adjustable by means of a leaf spring j moved by a screw k. The electrostatic forces between the plates e, a apply a torque to the moving system proportional to the angle of deflection, as long as this angle is small, and to the square of the voltage applied to the fixed plates. The arrangement is such that this torque opposes that due to the suspension, and the resultant torque may be reduced to any desired extent by adjusting the applied voltage. The plates e may be replaced by wires, gauze or conducting films deposited on insulators. By a combination of electrostatic forces and normal elastic controlling forces acting on the moving system, a non- linear relationship between the deflection and the resultant restoring force may be produced, for example electrostatic repulsion may take the place of stops.

Abstract: 375,821. Preparation of pulp. WESTAD, D., Bygd÷y, near Oslo, Norway. March 30, 1931, No. 9634. Convention date, May 27, 1930. [Class 96.] Cellulose raw materials after treatment with gaseous sulphurous acid whilst in a moist condition, and before the usual digestion at elevated temperatures, are subjected to an impregnation with digestion liquor at low temperatures, preferably below 70 C., and under a pressure of several atmospheres, preferably more than five, by forcing liquid or gas into the impregnation vessel. The preferred impregnation temperature is 10-35 C. and the preferred pressure is 10-30 atmospheres. In an example, the tanks 1, 2 are charged with wood chips containing say 32 per cent moisture, and SO2 gas introduced. After 5 mins. an impregnating solution of calcium bisulphite, containing sufficient lime to combine with the SO2 to form a digestion liquor of the usual composition is introduced. The tanks are subjected to a pressure of 6 atmospheres for 6 hours at 20 C. The contents are run into the preheating vessel 3, heated to boiling point and after 3 hours transferred to a digester 4 or 5 and digested completely in 6 hours. The preheating vessel 3 alternately receives chips from the tank 1 for the digester 4 and from the tank 2 for the digester 5. The containers 1, 2, 3 are preferably composed of a conical main portion and a non-symmetrical cup-shaped bottom portion, having a deepened part in which the discharge opening is placed eccentrically, this arrangement facilitating rapid and complete emptying of the contents. To ensure thorough mixing, a pump may circulate material from the bottom to the top of the impregnating tanks 1, 2, and also, during transfer of the material, from the bottom of the vessel receiving the material to the top of the vessel being emptied.

Abstract: 1499909 Expandable mandrels L PERSSON 10 March 1975 [19 March 1974 12 Nov 1974] 9881/75 Heading F2U An expandable mandrel for a bobbin comprises one or more portions which automatically expand and contract as the bobbin is positioned on and removed respectively, the action being initiated by the movement of the bobbin. The mandrel may be operated pneumatically, hydraulically or mechanically. As shown, the casing 4 has hinged expanding portions 5, 6 operated by a pull-rod 10 of a pneumaticallyactuated piston 3 slidable over a tube 34 through which compressed air is supplied from an inlet 17. Valves 7 and 9 are provided, the first being automatically controlled by a trip lever 32 in the path of the bobbin. When a bobbin is threaded on and the trip lever 32 depressed thereby to close the exhaust port 19 from the cylinder space 18, the piston 3 is forced down against the action of a spring 13 to expand the portions 5, 6 which are provided with hinges 5c, 6c of friction material (rubber). When the bobbin is first pulled to remove it from the mandrel it lifts an attached part 20 of the valve 8 off its seat 22 against the action of a tension spring 23 to exhaust the compressed air from the space 18 and tube 34 out through a port 30 so that the spring 13 can lift the piston 3 and contract the portions 5, 6. In a second embodiment, Figs. 3, 4, 5 (not shown), the cylinder (4) for the piston (3) is movable between two positions on a slide valve (41), the movement being limited by a pin (46) and the two positions being located by a ball catch 49. When a bobbin is threaded on it abuts fin-shaped stops (53) to carry the cylinder, to the position where compressed air is fed through a port (44) to lift the piston and an attached portion (4a) to expand hinged portion (38). When the bobbin is first pulled to remove it from the mandrel it lifts the cylinder to a position where the compressed air is exhausted via, an annulus (50) in the valve and port (51) so that a spring (13) can return the piston and contract the hinged portion. In a third embodiment, Figs. 6, 7 and 8 (not shown), the hinged portions are expanded by a spring (13) which forces a piston (3) down when the compressed air supply to the underside of the piston is shut off when the bobbin is brought to bear on fin-shaped stops (83). The piston is attached to the mandrel casing by a pull-rod (90). When. the bobbin is first pulled to remove it from the mandrel it lifts the top part: of a slide valve (71) to the limit of a stop (95) where the compressed air supply is reconnected to the underside of the piston via ports (75, 74 and 70).
