Title: Improvements relating to navigational compasses
IPC: G01C17/30
Filed: 1931-03-11
Abstract: 366,764. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc., Manhattan Bridge Plaza, Brooklyn, New York, U.S.A.-(Assignees of Wittkuhns, B. A. ; 5, Garden Place, Chatham, New Jersey, and Sperry, E. A. ; 1505, Albermarle Road, Brooklyn, New York, both in U.S.A.) March 11, 1931, No. 7484. Convention date, March 28, 1930. [Class 97 (iii).] A frame rotatable about a vertical axis carries a gyroscope and an earth inductor device controlling means for applying a torque to the gyroscope to cause it to turn the frame into the magnetic meridian. In the form shown the frame 2 is rotatable about a vertical axis 9<1> in the spider 10 which is supported in gimbals 12, 13. The earth inductor armature 1 rotates about a vertical axis in the frame 2 and is driven by the motor 6 which preferably includes a flywheel 8 for stabilizing the frame 2. The current induced in the armature 1 is led off through the commutator 4 and brushes 5 fixed to the frame 2 to the amplifier 17 and torque applying motor 18. The latter applies a torque about the horizontal axis 16 on which the gyro casing is mounted in the frame 2 and causes the gyro to precess carrying the frame 2 around the axis 9<1> with it. A compass card 24 mounted on the shaft 9<1> may drive a transmitter 21 operating repeaters 19, 19<1> or a follow-up device may be used. To prevent wandering of the normally horizontal rotor axis a pendulous or liquid level is adapted on undue inclination to operate a solenoid causing a cup shaped cage to engage an extension on the gyro casing and centralize the gyro. Alternatively, one end of the gyro casing is provided with an axial bore merging into a transverse bore through the ends of which jets of air are forced by the rotation of the rotor. A pair of shields extend upwardly and downwardly respectively from the frame 2 and obstructs the jets differentially when the gyro is tilted causing a restoring torque to be applied.

Title: Improvements in or relating to processes for the purification of gases
IPC: B01D53/02
Filed: 1923-03-19
Abstract: Gases to be used for catalytic processes, such as burner gases for use in the catalytic production of sulphuric acid, are purified from traces of finely divided inorganic solids by the use of activated carbon or charcoal, of high adsorbing or decolorizing power, prepared for example as described in Specification 10126/14, [Class 90, Non-metallic elements].  The solids may in some cases be enveloped in liquid particles or liquid clouds.  The purification may be combined with the formation in the gas of a condensation product, which may be effected in the filter chamber.  For example, in the manufacture of sulphuric acid, gases containing steam and sulphur trioxide may be caused to deposit sulphuric acid on the carbon by maintaining the filter chamber at a suitable temperature.  A suitable concentration of steam may be maintained for the purpose.

Abstract: 456,809. Date indicators. PAAUWE, P. J., 54, Pieter van der Doesstraat, Amsterdam. March 18, 1936, No. 8088. [Class 106 (iv)] A disc 2 rotating with the hour hand of a watch or clock carries a pin 1 which engages a lever 3 pivoted at 4 to the overhanging part of a lever 7 pivoted at 8. The lever 3 is thus moved into contact with a step 6 on the lever 7 and this latter lever is then rocked clockwise about its pivot 8 until the pin 3 moves along the inner side of the lever, Fig. 2. The pin 1 then restores the lever 7 by engaging the surface 10 but on the next revolution of the disc 2 the pin 1 cannot engage the lever 3 and the lever 7 is not rocked. Towards the end of this next revolution the pin 1 moves the lever 3 into the position shown in Fig. 1 and the cycle recommences, the lever 7 thus being rocked once every twenty-four hours. The lever 7 carries pawls 11, 14, 18 engaging teeth on the date figure, day-name and month-name rings 12, 16, and 17 respectively. The pawl 18 is normally held out of action by a lever 20 but on the 30th of the month the end of the lever 20 moves into a depression 21 in the date ring 12 and allows the pawl 18 to move nearer to the month-name ring 17. If the month has thirty days the corresponding tooth on the ring 17 projects so far that at the next movement of the lever 7 the pawl 18 advances the month-name ring. If the case of months having thirty-one days the corresponding teeth on the ring 17 do not project so far and consequently are not engaged by the lever 20 until the date ring 12 has moved a further step to indicate " 31 " and to allow the lever 20 to fall into a deeper notch 28 in the ring 12. To move the date ring 12 from " 30 " to " 1 " at the end of a 30-day month, a slider 22 is provided which is moved to the left by the engagement of a pin 25 on the slider with a notch 23, the notches being provided only in those positions corresponding to 30-day months. The slider is then returned by an arm 27 of the lever 7 and advances the date ring 12 by a projection 26a engaging teeth 26.

Title: Improvements in or relating to siloxane elastomers
Filed: 1957-03-12
Abstract: Siloxane elastomers comprise (1) a polysiloxane of unit formula RCH2CH2Si(Me)O, where R is a perfluoroalkyl radical containing 1 to 10 carbon atoms, and which may contain up to 10 mol. per cent of copolymerized units of the formula R12SiO where R1 is methyl, phenyl or vinyl, and (2) a filler.  The polymers have a viscosity of at least 1,000,000 and preferably above 10,000,000 c.s. at 25 DEG  C. They are prepared by polymerizing the corresponding cyclic trisiloxanes as described in Specification 832,489.  The tri-siloxanes themselves are described in Specification 832,487. Suitable fillers are titania, zinc oxide, ferric oxide, clay, diatomaceous earth, crushed quartz, fume silica, silica aerogels and silica xerogels.  These fillers may be modified with silanes so as to attach organosilyl groups to the surface, as described in Specification 669,759. Vulcanization may be effected in the usual way, e.g. heating with a per compound such as benzoyl peroxide, tert. butyl perbenzoate and per-acetate, dicumyl peroxide and chlorobenzoyl peroxides; adding an alkylpolysilicate and a carboxylic acid salt such as lead naphthenate or dibutyl tin diacetate; or, when the base polymer contains Si-bonded hydroxyl groups, adding small amounts of an hydrogen-containing siloxane, followed by a carboxylic acid salt such as lead 2-ethylhexoate.  The last two methods are performed at room temperature.  The elastomers have high tensile strength and elongation and they swell less than 20% in hydrocarbons such as toluene and isooctane and less than 10% in diester and lubricating oils.  They are useful for making hoses, seals, fuel tank linings and electrical insulation.

Abstract: 713,843. Toothed gearing. CHAMBON, Ltd. April 9, 1951 [April 7, 1950], No. 8232/51. Class 80 (1) A gear 18 on a driven shaft 19 is driven at a cyclically varying speed from a carrier member 13, 14 secured to a hollow-driving shaft' 12 rotatably mounted upon the shaft 19. The gear 18 is engaged by a gear segment 17 on an arm secured to a gear 23 pivoted on an axle 15 of the carrier 13, 14. Also pivoted on the carrier is a gear 24 in mesh with the gear 23 and controlled by an arm 26 having a pin 27 engaged in a camslot in a stationary disc 30. Thus a direct drive from the shaft 12 to the gear 13 through the segment 17 is modified by the movement of the gear 24 derived .from the cam slot to give a cyclic variation. This variation may be sufficient if desired to reduce the apeed of the driven gear 18 to zero.
