IPC: C06B45/10
Filed: 1961-09-11
Abstract: 1283691 Propellent compositions THIOKOL CHEMICAL CORP 11 Sept 1961 32585/61 Heading C1D [Also in Division C3] A solid propellent composition comprises an inorganic oxidizer and a cured isocyanateterminated polyester which acts as fuel and binder, said polyester being derived from a polymer of an unsaturated C 18  fatty acid, for example linoleic or oleic acid. The composition is made by condensing the fatty acid polymer with a polyhydric alcohol to form a polyester, reacting the polyester with a polyisocyanate, incorporating the solid oxidizer and a curing agent, and then curing the mixture. Lists of suitable polyhydric alcohols, polyisocyanates and curing agents are given. In Example 1, a mixture of dimer and trimer of linoleic acid is heated under nitrogen with diethylene glycol, water removed by distillation, and the product heated with para-tolylene diisocyanate. This pre-polymer is mixed with castor oil as a curing agent, aluminium powder, and ammonium perchlorate of coarse and fine particle size, and cured at 100‹ F. to a rubbery solid. In other examples, the curing agent comprises ethylene glycol monoricinoleate and trimethylol propane, dihydroxy castor oil, and trimethylol propane and the dihydroxy polyester produced in the first step of Example 1. By increasing the amount of aluminium powder, the specific impulse of the propellent may be increased without increasing the burning rate. Other ingredients which may be included in place of or in combination with the aluminium powder are ferrocene, magnesium hydride, iron oxide, or iron, nickel, or cobalt pyromellitates. The propellants formed are substantially free from gas cracks and may have a higher loading of inorganic oxidizer, and lower burning rate, then those previously proposed.

Abstract: 1,222,989. Respiratory apparatus. ROBERTSHAW CONTROLS CO. 9 July, 1968 [10 July, 1967], No. 32655/68. Heading A5T. A device for controlling the oxygen and air supplies in a breathing apparatus comprises a demand regulator 10 providing oxygen through an inlet 36 to a mixture chamber 34, there being an air inlet to the mixture chamber controlled by a one way valve 54, 56, and there being a first variable nozzle 38 providing the oxygen flow into the mixture chamber as a jet and a second nozzle 45 disposed downstream of the first and arranged to define a mixture of air and oxygen to the outlet As shown, the device controls the proportions of oxygen and air in a breathing mixture according to altitude, the oxygen passing into the mixture chamber 34 through the inlet 36 against the action of a spring loaded nozzle member 38, and the atmospheric air entering the chamber through the flap valve 54, 56 and through an opening controlled by an aneroid bellows 64 which ensures that less air enters the device at higher altitudes. The air inlet 70, 74 to the device may also be controlled manually with a shutter 78. In use, at ground level, the aneroid bellows valve 64 is open and the user (in a face mask or helmet) inhales air through the flap valve 54, 56, and the outlet 32. At high altitudes, the user inhales oxygen on inhalation demand from the regulator 10 and through the first nozzle 36, 38, the second nozzle 45, and the outlet 32. At intermediate altitudes, the regulator 10 supplies oxygen on inhalation demand and the oxygen issuing as a jet from the nozzle 36, 38 entrains a primary flow of air through the flap valve 54, 56, the mixture chamber 34, and over the outer surface of the second nozzle 45 into the outlet 32. As the oxygen flow increases, the spring loaded nozzle member 38 attains a new equilibrium position and the oxygen entrains a secondary flow of air into the second nozzle 45, this mixture of air and oxygen then mixing with the primary air flow at the outlet 32. The spring loading of the nozzle member 38 is adjustable at the spring mounting 48 and the position of the aneroid bellows 64 is adjustable at its mounting 66. The oxygen demand regulator 10 may comprise (Figure 1, not shown) a spring biased diaphragm (12) actuating an outlet valve (22) from an oxygen source.

Title: Improvements in or relating to photographic shutters
IPC: G03B9/22
Filed: 1939-12-22
Abstract: 536,112. Photographic shutters. DECKEL, F. Dec. 22, 1939, No. 32782. Convention date, Dec. 23, 1938. [Class 98 (i)] To prevent light passing between the closed blades of a multi-blade shutter from reaching the sensitive material, another shutter, opening and closing approximately simultaneously with the first, and preferably comprising more than one blade, is located in the light path. In the form illustrated, a multi-bladed shutter comprising blades 23 with a rotary operating ring 53 is arranged on one side of a partition, wall in the casing, there being a second shutter having two blades 29, 37 on the other side. Operation of the release 64 rocks a two-armed lever 3 clockwise, and a pin 9 extending from it through a slot in the partition wall and engaging a slot in the blade 29 of the second shutter causes this shutter to open, the blade 37 being moved by means of a pin and slot connection 33, 35 with the blade 29. The release 64 then engages a pawl 62 and moves it to unlatch the operating ring 53, which operates the blades 23 to make the exposure. When the shutter blades 29, 37 are in the open position a pin 69 on the lever 3 engages in a slot 71 of a spring-pressed pawl 55, thus maintaining the second shutter open during the exposure. At the end of the exposure, a shoulder 57 on the ring 53 engages the pawl and moves it to unlatch the pin 69, allowing the second shutter to close. Alternatively, the release may operate directly only the second shutter 29, 37, which in its turn releases the first, the latter then effecting the closure of the second shutter. The two shutters may be operated by a common source of power, or separate sources.
