Title: Processes of making zeolites
IPC: C01B33/46
Filed: 1929-09-26
Abstract: 319,746. Permutit Co., (Assignees of Bruce, W. M.). Sept. 27, 1928, [Convention date]. Double silicates. - Base-exchanging silicates are obtained by mixing solutions of sodium silicate and aluminium sulphate or chloride and adding to the mixture a solution of sodium aluminate. Iron chloride or sulphate or an a.cidreacting solution of a salt of other amphoteric metal oxide may replace the aluminium salt, and an alkaline-reacting solution of other amphoteric metal oxide the sodium aluminate. Instead of sodium salts potassium salts may be used; or some potassium may be caused to be present, for instance by adding potash alum to the aluminium sulphate, or by using to make the solutions employed waste leach liquors attained from the treatment of zeolites produced by dry methods, which usually contain potassium. The proportions are so chosen that at the end of the reaction the mother liquor is alkaline, so that the ratio of sodium oxide to alumina in the product will be 1 : 1; but that of alumina to silica may be widely varied, for instance from 1: 1 to 1: 13, a ratio of 1 : 5 giving a good result. The use of solutions sufficiently concentrated to give a full-volume jelly is advantageous, but dilute solutions may also be used. The product may be pressed and then dried, or be dried only, at a low temperature, or be air-dried. It is finally washed with water. Specification 279,466 is referred to. A statement of the art refers to precipitating an alkali metal silicate with a salt of a metal of the iron group, and reacting the precipitate with alkali metal aluminate to form baseexchanging compounds.

Title: Improvements in or relating to industrial trucks having a hydraulic circuit for performing a load handling operation
Inventor: FULLBROOK MAXWELL SIDNEY
IPC: B66F9/20
Filed: 1967-06-26
Abstract: 1,221,645. Masked lift trucks. LANSING BAGNALL Ltd. 13 June, 1968 [26 June, 1967], No. 29382/67. Heading B8H. [Also in Division F2] In a masted lift truck, the spool of a directional valve 24 in the hydraulic circuit of a lift ram 14 is connected to a hand lever 34 by a linkage in which links 31, 32 are connected by the coil and armature of a solenoid 36. The hydraulic circuit is associated with an electrical circuit for energizing the solenoid whereby, when the electrical circuit is closed, the solenoid is energized and the links 31, 32 are movable in unison to move the valve spool to cause the ram 14 to be extended, and when a limit switch in the circuit opens, the solenoid is de-energized and a spring returns the valve spool to its neutral position. In the electrical circuit, there are provided two limit switches, one of which is normally open and arranged to be closed by movement of the hand lever 34 out of its neutral position, and the other of which 41 is mounted on the mast and is arranged to be closed when engaged by a cam block 46 on the lifting carriage 15. In operation, if the switch 41 is closed, closure of the other switch by downward movement of the hand lever will close the electrical circuit to energize the solenoid and the hydraulic pump motor. Further movement of the hand lever will then effect movement of the links 31, 32 to move the valve spool to the "lift" position. When the carriage opens the switch 41, the solenoid is de-energized, the valve spool returns to the neutral position and the pump motor will also be cut off. On moving the lever 34 upwardly, the link 32 moves towards the link 31 and then moves the link 31 to move the valve spool to move in the other direction to allow the carriage 15 to fall under gravity. A by-pass circuit, controlled by a switch 50 is provided for the limit switch 41. The hand lever 51 is rigidly connected to a valve spool in the hydraulic circuit of the tilt rams 18. In a modification (not shown), the limit switch 41 controls the range of movement of a side shifting attachment on the load carriage.

Title: Improvements in throttle control for internal combustion engines
IPC: F02D9/00
Filed: 1945-11-07
Abstract: 603,956. Spray carburetters. FORD MOTOR CO., Ltd. Nov. 7, 1945, No. 29660. Convention date, Jan. 14, 1944. [Classes 7 (ii) and 7 (iii)] In an engine having two carburetters 11, 12 attached to adapters 48 and communicating through ducts 13 with the intake manifold 14, the throttle valves are actuated by a rod 24 rotating a shaft 27 through a lever 25, one of the valves being connected by a link 30 to a lever 28 rotated by the shaft 27 and the other by a link 32 to a lever 29 pivoted at 40 to the lever 28, a spring 36 urging both valves to their closed positions. Initial movement of the rod 24, connected to the accelerator pedal, rotates the lever 28 to open the right-hand valve, but the lever 29 merely rotates about the pivot 40, leaving the left-hand valve unaffected. When the hooked end 34 of the lever 29 contacts a stop, further motion of the rod 24 causes the left-hand throttle valve to open at twice the rate of the right-hand, so that they reach the fully open position at the same time. Air is supplied to the carburetters through a header 15 connected by passageway 16 to air cleaners, and the carburetter adapters 48 have jackets 52, connected at opposite ends to the exhaust manifolds, forming charge preheaters. In a modification, Fig. 13, the intake systems for the banks of cylinders are completely independent and the carburetters 111, 112 are of dual construction, the operation of the throttle valves being the same as above. A small passage 150 may be provided between the intakes at each end for pressure equalization and the carburetters 111, 112 may be mounted horizontally instead of vertically by means of suitable adapters.

Title: A protective circuit arrangement for transistors
IPC: H03F1/52
Filed: 1960-08-31
Abstract: 925,027. Protective arrangements. SIEMENS & HALSKE A.G. Aug. 31, 1960 [Sept. 1, 1959], No. 30092/60. Class 38 (5). [Also in Group XL (c)]  A normally saturated transistor is protected against overload by connecting in its output circuit, in series with the load, a switch device in parallel with a capacitor and by controlling the switch in dependence upon the transistor output voltage so that switch is closed only when the transistor is saturated. When transistor T1 is switched on by a voltage applied to its base, current flows through a capacitor C, rectifier D, the output path of the transistor and the load R, and if the transistor saturates the point A falls to earth potential. Accordingly, a transistor T3 becomes non-conducting and a Zener diode conducts, rendering a transistor T2 conducting. This provides a path for the load current. If the load current had been excessive, for example due to short a circuit, the transistor would not have saturated and transistor T2 would not have become conductive so that only the charging current for capacitor C would have been passed by the transistor. Excessive current due to a subsequent fault will also cause the transistor T2 to become non- conductive. The diode D prevents capacitor discharging through transistor T2 and resistor Rc provides an alternative discharge path. A diode R1 isolates the point A from transistor T3 so that the protective circuit T2, T3 may be used for a number of switching circuits such as T 1 by parallel connection at V. In an alternative circuit (Fig. 4, not shown), the load is connected in the emitter circuit of transistor T1 and the series transistor in the collector circuit.
