Abstract: 1,044,613. Valves. OHIO BRASS CO. Sept. 23, 1963 [Sept. 21, 1962], No. 37408/63. Heading F2V. [Also in Division F1 Upon raising a spring-centred spool 38 fluid flows from an inlet 32 to a passage 49 and an exhaust passage 99 is. closed; the fluid in passage 49 unseats a valve 66 against a spring 78 and flows through one or more valve openings 92 into a passage 49a and a motor port 36a. The greater the movement of valve 60 the greater the flow into the motor. The fluid in passage 49 also passes through an orifice 91 in a nut 76 and acts on a plunger 08 which unseats a valve 66<SP>1</SP> opposite to and identical with valve 66, so enabling fluid exhausted from the motor to flow from port 36 to exhaust port 34 via passages 48, 48a and 102. The nut 76, 76<SP>1</SP> of each valve is threaded on a balancing piston 70, 70<SP>1</SP> and whilst the valves can move independently of the pistons the latter are loaded by springs 86, 86<SP>1</SP> and have a lost-motion connection with the valves. The opposed cylinders 72, 72<SP>1</SP> housing the balancing pistons are in communication with passages 49, 48 respectively. The motor may be single or double-acting. Any pressure increase in the port 36 due to the load moved by the motor will act through orifice 91<SP>1</SP> against the plunger 58 to oppose and partly cancel the pressure force in passage 49 on the opposite end of the plunger, whereby the spring 86<SP>1</SP> tends to reseat valve 66<SP>1</SP> and reduce the flow from the port 36 so that the velocity of lowering of the load remains constant. The valves 66, 66<SP>1</SP> may be separate from the spool valve. Relief valves 94 are provided and the spool valve has metering notches 50.

Title: A process relating to the recovery of unsymmetrical dimethylhydrazine from aqueous solutions by distillation
Filed: 1956-12-11
Abstract: Aqueous solutions of unsymmetrical dimethylhydrazine (UDMH) are concentrated by distillation in the presence of 1 to 30 wt. per cent of sodium hydroxide based on the aqueous solution, the concentrated solution being obtained as distillate.  Salt-free aqueous UDMH obtained by evaporating the synthesis liquor from a modified Raschig process is fed through a line into which concentrated aqueous sodium hydroxide is injected and the mixture introduced into a fractionating column heated by a reboiler. Dilute caustic soda is removed as bottoms and returned to the synthesis reaction.  Concentrated UDMH is removed overhead to a condenser where a portion of the condensate is refluxed and the remainder withdrawn as product.  In an alternative mode of operation the synthesis liquor is not evaporated and the salt contact thereof is taken into account by regarding it as equivalent to half its weight of caustic soda.  In an example, 12.8 lbs. of caustic soda is added to 100 lbs. synthesis liquor containing by weight 3 per cent UDMH, 87 per cent water and 10 per cent salt which is fed to the third plate of an 11 theoretical plate column operated at a 75 : 1 reflux ratio.  A 90 per cent recovery of 95 molar per cent UDMH is obtained.

Title: Production of polymer foam
IPC: C08J9/00
Filed: 1956-12-24
Abstract: Foamed polymers are obtained from a monomeric alpha-chloroacrylic ester of a monohydrocarbon having 1-6 carbon atoms, by dissolving the monomer in an organic compound which is soluble in such monomer but not in the polymer, polymerizing the monomer solution to obtain a mixture of a solid polymer and the separated organic compound, heating the mixture to 135-225 DEG  C. to decompose the polymer partially and thus generate bubbles within the mixture, and cooling below said temperature range before the bubbles merge within the mixture or escape from its surface.  The preferred monomer is methyl-alpha-chloroacrylate and the organic compounds used are alcohols, oily to waxy hydrocarbons boiling above 250 DEG C., e.g. paraffin oil or wax, or silicone oils, e.g. oily dimethyl siloxane polymers; advantageously tertiary butyl or higher alcohols are added to accelerate the formation of the foam. In Example (1) 20 ml. steam distilled methyl-alpha-chloroacrylate were cooled to -20 DEG  C. and separated from ice crystals formed; 0.25 gs. oily dimethyl siloxane polymer were added and the resulting solution polymerized by exposure to diffused daylight. The product obtained showing a slight haze, due to separation of the silicone oil, was heated to 160 DEG  C. in a circulating air oven and the cooled polymer being then converted to a foam of about 27 times the original volume, the bubbles in the foam having a diameter of from 0.1-0.5 mm.  In example: (2) paraffin wax was employed; (3) paraffin oil; (4) terbutyl alcohol and silicone oil with dibutyl tin diacetate as catalyst; (5) mixture of a silicone oil, and (a) methyl alcohol, (b) isopropyl alcohol, and (c) tert. butyl alcohol were used.

Headings F1G, F1J and F1L. Energy is generated by injecting a fluid fuel into a combustion chamber containing solid chromium trioxide with which the fuel reacts hypergollcally to produce high temperature gases. The gases are expelled through the nozzle 2 of a rocket, turbine or other prime mover. Compressed air within a compartment 21 acts via a piston 19 to force fuel from a compartment 18 through a valve 12 into the combustion chamber 25, where the fuel passes through a cylindrical hole 6 in a block of solid oxidizer 8 in the form of chromium trioxide, reacting hypergolically with the latter to produce the propulsive gases. The fuel flow is controlled by adjustment of the valve 12 by means of a motor under manual or radio control. The invention may be applied to an aircraft jet propulsion engine, the fuel reacting hypergolically with the chromium trioxide in an auxiliary combustion chamber to burn about 10% of the fuel whereby the remainder of the fuel is heated to a temperature above its flash point and ignites spontaneously when injected into the air in the main combustion chamber of the engine. The fuel may be alcohol, gasoline, jet petroleum, rocket petroleum, diesel fuel, napalm or paraffin.

Abstract: 1310272 Focus control devices RICOH KK 19 Aug 1970 [13 Oct 1969] 39825/70 Heading G2A [Also in Division H4] An automatic focus control device for a photographic camera comprises a slidable member 2 movable to rotate the camera distance setting ring 1; a drive member 3 movable along a path substantially parallel to the path of movement of the member 2; a spring 4 biasing the drive member to the right, as seen; a lever 8 for displacing the members 2, 3 to the left; a locking member 6 holding the drive member 3 in its extreme left position; a pin 16 and hook 15a for locking the members 2, 3 together: photo-electric transducers (α, #) Figs.2, 3, (not shown), operable to detect when a subject is correctly focused by the camera; and an electromagnet MG operable in response to such detection to release the lock between the members 2, 3 so that the slidable member 2 ceases to rotate the distance setting ring 1. The device is shown in a position ready for an exposure. Sequence of events. Depression of a shutter button pivots the locking member 6 thereby freeing the members 2, 3 to move together to the right under action of the spring 4. This movement causes the member 2 to rotate the ring 1, thereby displacing a taking lens (TL) and, via gearing 21, 22 and ring 23, a light receiving lens (RL) relative to the subject. The transducers (α, #) receive light from the subject through the lens (RL) and when the subject is focused in a focal plane (P) of the lens (RL), the output from the transducers is equal. This balances a bridge circuit (Fig.3), switching on a transistor (T4) to energize the electromagnet MG, which attracts an arm 15b, thereby freeing the member 2 from the drive member 3. The latter continues to move to the right and engages a shutter release member 14 to take a photograph. Film advance rotates a disc 11 causing a pin 12 thereof to rotate the lever 8 clockwise, as seen. The lever 8 entrains the members 2, 3 and returns the device to its cocked state.
