A safety control means for the supply of fluid under pressure from a common source of supply to separate supply lines, e.g. to actuate the cylinders associated with the brake bands of epicyclic gearing, comprises a group of two or more selector valves 4b, 7b or 9b each of which controls a separate supply line 13, 14 or 15, respectively, wherein on actuation of any selector valve to connect its supply line to the source of supply 11, fluid under pressure is also applied to the other valve or valves of the group to prevent actuation thereof whilst the selected valve remains in position to allow the flow of fluid to its associated supply line. The valves 4b, 7b and 9b are housed in bores 5, 8 and 10, respectively, and each has a piston 4a, 7a or 9a located above and joined to it by a hollow stem 17 and a freely movable piston 4c, 7c or 9c located below it. Each valve is moved axially in a bore by a solenoid energized actuator 1, 2 or 3, against the action of a spring 18. Normally each valve is disposed in its upper position and when, e.g., valve 4b is moved by the actuator 1, exhaust line 12 is closed and pressure inlet 11 is connected with supply line 13. Auxiliary line 19 also supplies fluid to chambers below piston 7c and valve 9b to counteract any action by energization of their actuators 2 and 3. Similar auxiliary lines 20 and 21 connect with supply line 14 and lines 22 and 23 connect with supply line 15. In a further embodiment a selected valve, e.g. controlling a reverse gear, is moved back to the normal position if another actuator is inadvertently energized.

Abstract: 558,466. Teaching shooting. SMEATON, 1. D., and SOCHACZEWSKI, S. June 29, 1942, Nos. 8894 and 11388. [Class 119] A dummy sub-machine gun, automatic pistol or the like is constructed with a selfcontained spring-driven mechanism whereby the firing of a series of shots in single-shot manner may be simulated, a target-pricking device, also within the weapon, being actuated each time the trigger is pulled. The target pricker is a captive dart 60 at the front end of a spring-retracted rod 61, the. dart being raised, as it is projected, by rocking-arms 64, pivoted at 66, so as to prick the target in the line of sight of the weapon. The rear end of the rod is engaged by a series of teeth 21 located centrally on the periphery of a spring-driven drum 13, Fig. 4, the drum being freed for rotation in a step-by-step manner by two sears 38, 38<SP>1</SP>, which engage alternately with staggered teeth 20, 22 carried by the drum at either side of the teeth 21. The sears are connected by links 46 to arms 48, pivoted at 42, which are spring-pressed against two staggered sets of rollers 51 (one set only being seen in Fig. 2A), the carriers 49 of which are integral with a ratchet wheel 53. The ratchet wheel is driven, one step at a time, by a pawl 37 pivoted to the trigger 35. Each trigger operation, therefore, results in the retraction of one of the sears and the engagement of the other with the drum teeth 20, 22. The drum jerks forward to the extent of one of the teeth 21, the pitch of which is half that of the other teeth, and imparts a target-marking impact to the dart rod 61. Specification 553,468 is referred to. Fig. 2A also shows the pistol-grip 17 of a sub-machine gun pivoted at 82 to the stock and pressed forwardly by a spring 85 so as to engage a cross-pin 88 with an arm 90 on the trigger, whereby the trigger is locked until the gun is correctly held against the user's shoulder with a pressure that overcomes that of the spring 85.

Abstract: 468,405. Coking processes. GRIGGS, A. R. March 25, 1936, No. 8931. [Class 55 (i)] In the carbonization of coal or the like by the circulation therethrough of hot combustion products, and wherein the sensible heat in a carbonized part of the charge is transferred to and used to carbonize another part, gas of high calorific value evolved when combustion is reduced or arrested is taken off and stored separately from the gas of low calorific value containing a high proportion of combustion products. A combustion chamber 2 with air supply 3 is arranged above a retort 1 operated by downward distillation, the combustion products being drawn downwardly by a pump 4 and pipe 5, the cooled mixed distillation gas and combustion products being returned by a pipe 6 to the top of the retort, and surplus gas being bled off through a valve 7. After sufficient heat is stored in the upper part of the carbonized charge, the air supply at 3 is shut off, and valve 8 opened admitting gas to purge the charge of poor gases, valve 9 being closed and the gases evacuated through valve 7. Valve 9 is then opened, and valve 7 closed and gas circulation takes place down the retort the heat from the upper part being transferred to the lower part, and surplus gas being bled off through valve 8. In a modification, an external combustion chamber filled with checker bricks is used, and the gases passed upwardly through the retort, an increased supply of heat being obtained from the combustion chamber. Steam may be added to the circulated gases before they pass through the charge, either as they enter the combustion chamber, or the retort, so that the calorific value of the gases is reduced by the addition of water gas or by decomposition of the hydrocarbon gases. Specification 469,607 is referred to.
