Title: Improvements in or relating to fluid control valves
IPC: F16K51/00
Filed: 1958-03-25
Abstract: 845,145. Valves. ANDERSSON, H. A. P. March 25, 1958, No. 9542/58. Class 135. A blow gun comprises a spring closed valve member 6 actuable by a longitudinally displaceable stem 9, which is slidably guided in a sleeve 11 screwed into a body 1 which also forms a handle. A stop to limit the opening of the valve is formed by a knob 10 at the end of the actuating stem abutting the sleeve 11 and a further stop 14 surrounding the stem enables the valve to be held open permanently by screwing the sleeve into the body so that the stem 9 is also moved. The sleeve may be held in position by a lock-ring 12 or by a spring pressing a friction stud into contact therewith, and the valve stem may be in two parts.

Filed: 1935-03-28
Abstract: 459,213. Controlling variable-speed gearing. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. March 28, 1935, No. 9679. Application for addition to 443,718. Void [Abridged as open to inspection under Sect. 91 of the Acts, Sept. 30, 1935]. [Class 80 (ii)] In a motor vehicle a free-wheel tail-clutch 14 is unlocked during a gear-change, the tailclutch, main-clutch 12 and conventional gearshifter lever 24 being actuated respectively by power-cylinders 22, 18, 20, all operatively connected with the engine induction-system 34 by release of the accelerator pedal 30, which controls a common valve 26. The doubleacting gear-establishing motor 20 is pivotally mounted at 82 and is biassed into the second- and-high-speed plane of actuation, by a spring 80, against the resistance of which it is manually moved into the low-and-reverse plane. The direction of longitudinal gear-establishing movement of the lever 24 is selected by a heel or toe operation of a treadle 46, which operates a two-way piston-valve 28 controlling the gearestablishing motor 20 and also the tail-clutch motor 22. The supply to the gear-establishing motor 20 may be throttled so that the tail-clutch motor 22 acts first.

Title: Circuit arrangement for comparing two binary numbers
Inventor: HENNIG HARTMUT
IPC: G06F7/02
Filed: 1966-03-04
Abstract: 1,111,626. Digital control systems. WERKZEUGMASCHINENFABRIK MAGDEBURG VEB. 4 March, 1966, No. 9721/66. Heading G4H. A circuit for determining the sign of the difference between two binary numbers representing a desired value and an actual value, and for indicating coincidence of the values comprises a plurality of binary stages 1, Fig. 1, a pulse generator 7 connected to the lowest order stage so as to periodically change the result of the comparison therein by an amount equal to the order of that stage, the output 6 from the highest stage being connected to a circuit adapted to distinguish between signals indicating that the sign of the difference is positive or negative, and a fluctuation between these conditions at the frequency of the pulse generator indicating that the desired and actual values are equal. The indicating device may be a lamp 8 which is unlit when the desired value is less than the actual value, flashes when they are equal, and burns continuously when the desired value is greater than the actual value. The binary stage chain by itself is arranged to produce no output when the difference is positive or zero. The input from pulse generator 7 makes the difference negative by one unit so that when the difference between the input numbers is actually zero there appears a periodic negative indication which causes the lamp to flash. The three signal conditions are separated by a circuit 10, shown in Fig. 2. The " 1 " output at 6, indicating that the desired value is greater than the actual, is passed by AND gate 12 to output 14 if there is no output from filter 16. The " 0 " signal is inverted at 11 and passes through AND gate 13 to output 15. The fluctuating signal passes through filter 16 where it is rectified and inverted to close both gates 12 and 13 so that no output is produced. The actual position may be controlled automatically by the comparator signal or by an operator guided by the indicator lamp 8.

Filed: 1944-05-19
Abstract: 582,347. Recorder - flutes. ROSE, MORRIS, & CO., Ltd., and ROSE, S. May 19, 1944, No. 9726. [Class 88 (ii)] Relates to the mouthpieces of musical wind instruments of the kind in which the wind passes through a narrow slot or channel and strikes a sharp edge or wind cutter 19, as in a recorder-flute 11. According to the invention the mouthpiece 10 has a thin end portion for insertion between the lips of the player and comprises a tube having a groove 25 in line with the wind cutter to form the air passage, a plug 23 being fitted in the tube and being formed with means for correctly locating it in relation to the groove. The mouthpiece may be made from mouldable plastic materials, such as cellulose acetate, or other mouldable materials such as metals and alloys. In the construction shown in Fig. 1, the wind cutter 19 is integral with the body 13, and into the latter is fitted a slightly tapered plug 23 a flat surface 24 on which projects slightly into and constitutes one wall of the slot 25. In a modification, Fig. 5 (not shown) the surface of the plug adjacent the slot is grooved longitudinally. In another construction, Fig. 7,. the wind cutter 191 is moulded separately, and the body 13 of the mouthpiece has a cavity 27 having its side walls 28 formed with obliquely undulant portions for receiving the wind cutter which is inserted from inside the rear end of the mouthpiece.

Title: Improvements in and relating to sustaining rotors for aircraft
IPC: B64C27/02
Filed: 1937-04-06
Abstract: 492,911. Aircraft with rotary wing systems. CIERVA AUTOGIRO CO., Ltd., and BENNETT, J. A. J. April 6, 1937, No. 9801. [Class 4] A lifting or sustaining rotor for a helicopter or a gyroplane includes a compound flapping pivot mechanism having two independent pivot axes or groups of axes #, #b, together with physical constraints interconnecting the articular mechanisms of the several blades in such a way as to prevent the fundamental component at least of the " non-differential flapping " from producing motion about the #b axis or axes or to prevent the coning and " differential flapping " from taking place about the # axis or axes, the # and #b axes, when projected on a plane perpendicular to the hub axis, being inclined at different angles to the radial blade-axes, so that a given angular flapping displacement is accompanied by a different change of blade pitch according as it takes place about a # or #b axis. According to the Specification, if the flapping motion of the rotor blocks is analysed into a Fourier series of harmonic terms, of which the fundamental expresses a periodicity of once per revolution, the expressions will differ in phase by an amount equal to the angular setting of the blades in the rotor disc and if the expressions are added together, those terms, the ratio of whose frequency to the fundamental frequency is an integral multiple of the number of blades, are additive and represent the components of " differential flapping." On summing the expressions representing the total flapping of the several blades, all the other terms, representing the components of " non-differential flapping," disappear. In one form, the rotor blades 14 are pivoted about the axes #b to a member 12 pivoted to the hub 10 about an axis #. In a modification, the #b axes are coincident, the pivots being formed by a cranked member. In another form, the member 12 is formed of two links hinged about coincident # axes and the links are connected to a slider movable axially on an extension of the rotor hub. In the case of a three-bladed rotor, the links, one for each blade, are pivoted in lugs on the rotor hub, and in a modification the links are connected by ball-ended links to a centrally disposed link connected by a ball-joint to the hub.

V-shaped handles or tow bars 33 connected at 34 to the inner and outer structures are provided, and additional handles or loops 36 are welded to the side members to form feet to prevent the truck from rocking too far. The sides of the truck taper inwardly and downwardly so that when the wheels are removed several truck bodes may be nested. Each wheel is mounted on a tubular stub axle 28 slidable within a sleeve 21 welded to lugs 22 welded to the axle beam 13, and a plug 31 is welded into the inner end of the sleeve. The plug is provided with a transverse pin 30 extending across a vertical slot, and carries a slotted latch member 29 which may be brought from a vertical latching position shown dotted in Fig. 4, to a horizontal position shown in full lines in which the axle and wheel may be withdrawn and removed from the body. A waterproof cover or lining may be attached by means of straps or hooks passed through loops 38.
