Title: Improvements in Screw Propellers for Aircraft.
Inventor: JEZZI PAUL GEORGES LEON
IPC: B64C11/00
Filed: 1918-05-09
Abstract: 126,153. Jezzi, P. G. L. May 9, 1918. Screw propellers.- The blades of an aircraft propeller are so mounted in sleeves on the propeller boss that they may be slid during flight in the directions of their lengths by mechanism controlled by a brake and clutch gearing. Nuts E freely mounted on the sleeves D carrying the blades engage with the blade shafts C and with worms F mounted on the propeller boss B, the worms being so connected through gearing to the propeller shaft A that they may be rotated in one direction or the other by the operation of a brake K<1> or a clutch P. Pinions G on the worm spindles engage with a wheel H having a sleeve H<1>, on which is mounted, through an overrunning clutch, a wheel J connected through gearing L, M with the member 0 in which the clutch P engages. When the brake is operated, the sleeve H' and its wheel H are prevented from rotating relatively to the propeller shaft, the pinions G then running over the wheel H so as to rotate the worms F, To rotate the worms in the opposite direction, the brake is disengaged, and the clutch is brought into engagement with the member 0, which then rotates with the shaft, thus rotating the wheel J and, through the overrunning clutch, the wheel H, in the same direction but at a greater speed than the shaft. To vary the pitch of the blades with the alteration of their length, projections R<1> are fitted on the blade shafts to engage in inclined slots R on the sleeves.

Title: Improvements in control mechanisms for cranes and other lifting appliances
IPC: B66C13/54
Filed: 1961-03-03
Abstract: 949,854. Controllers. H. TAX. March 3, 1961, No. 7898/61. Heading H2B. A torque is applied to the handle of an electric motor controller, e.g. in a crane, by an electric torque motor energized in accordance with the main motor current so that the operator may " feel " the load. The handle 1 is movable about two axes 2 and 3 to control separate motors. For one of the motors, 8, which is Ward-Leonard controlled, the handle actuates a variable resistance 5, and the torque motor is a D.C. one whose armature 7 is connected across an interpole 9 of the main motor and whose own field 10 is separately excited. The torque is adjusted by a field rheostat 11, and in the central, off, position of the control handle the field circuit is broken by a switch 12. The other main motor, not shown, is an A.C. one and the handle operates on a variable transformer 16. In this case the torque motor 18 is A.C. and has an adjustable winding 19 and a control winding 23, energized by a current dependant on that of the main motor but ampli - fied non-linearly at 22. The torque on the handle is thus not proportional to the load, but is arranged to give degressive feel.

Patent GB-685712-A (GB)
Title: Improvements relating to the treatment of aqueous liquors containing thiocyanate
Inventor: BOTT HUGH RANDALL
IPC: B01J41/00
Filed: 1950-03-31
Abstract: Aqueous industrial liquors, especially gasworks effluent liquors, which contain thiocyanate and other anions such as chloride are rendered non-toxic by removing the thiocyanate by passing the liquor through a bed of anion exchange material charged with hydroxyl ions, the material being of the kind which is capable of exchanging its hydroxyl ions for the anions of ammonium chloride and of regeneration when exhausted with ammonia, it having been found that such material also has the property of removing thiocyanate preferentially to other anions, e.g. chloride, present in the liquor so that these other anions largely pass through the bed unchanged.  The preferred material is a condensation product of a polyalkalene-polyamine and phenol, acetone or melamine with formaldehyde.  The capacity of the bed for thiocyanate removal may be increased by reducing the pH of the liquor either by adding a mineral acid or by saturating it with carbon dioxide.  The bed of material may be regenerated with a 12 per cent solution of ammonia or with a dilute solution of caustic soda or sodium carbonate.  In an example, the liquor, saturated with carbon dioxide is passed through a bed of material made by the condensation of tetraethylene pentamine with phenol and formaldehyde and activated with aqueous ammonia.  When the thiocyanate content of the collected effluent reached 30 parts per million the flow was stopped and the thiocyanate removed from the material by flowing ammonia solution through it.  The volume of purified liquor was 200 times greater than that of the thiocyanate-containing regeneration effluent. Specification 592,767 is referred to.

Patent GB-400084-A (GB)
Title: Improved timing mechanism for the operation of valves and like members
IPC: G01N1/10
Filed: 1933-03-21
Abstract: 400,084. Sampling granular materials; filters. BLOMFIELD ENGINEERING CO., Ltd., Finsbury House, Blomfield Street, London, and DURANT, H. T., The Lodge, Worth Park, Crawley, Sussex. March 21, 1933, No. 8523. [Classes 46 and 58.] A timing mechanism for controlling the operation of a valve or similar device, such as a sampling device for liquids or granular materials, comprises a bucket 19 connected to the valve &c. 17 and collecting fluid or other flowing material supplied through a pipe 35 from a float-controlled tank or other source at constant head, the arrangement being such that after collecting a specific quantity of material the bucket descends and operates the valve &c., a further operation of the valve occurring after the bucket has received a further predetermined quantity of the material. In the apparatus shown, the bucket 19 is pivotally mounted in a bridle 20 connected by a wire 15 to the lift valve 17, and is counterbalanced by an adjustable weight 31 so that it normally rests, in the position shown, on two pins 28 projecting from members 29 secured to the bridle. Two further wires 12 passing over pulleys 10 are connected to the bridle and to counterweights 14 in order to steady the movement. When the bucket has received a definite amount of fluid it sinks, raising the valve 17 ; after receiving a further quantity of fluid, it tips and empties itself, so rising to its initial position and closing the valve. The rate of supply of fluid may be adjusted by the use of one of a series of plugs screwing into the pipe 35 and having holes of different sizes, thus allowing the time taken for a cycle of operations to be varied. The period required for the valve to open may be varied by means of removable weights 45 on the valve, and the time during which it remains open by adjusting the counterweight 31. The valve body 17 may act merely as a weight, the actual valve being linked to it, or it may be formed of a number of parts connected together with lost motion between them and linked to independent valves, which are thus opened successively and closed simultaneously. The apparatus may be applied to control the filter elements of a thickening apparatus as set out in Specification 388,247.
