Title: Improved variable pitch air-driven bladed rotor unit
IPC: B64C11/34
Filed: 1955-03-23
Abstract: 767,907. Wind-motors. GENERAL MOTORS CORPORATION. March 23, 1955 [April 1, 1954; April 1, 1954], No. 8393/55. Class 110 (3). A wind motor comprising flyweights, responsive to centrifugal force due to the rotation of the rotor, rotatable about the longitudinal axis of each blade so as to move upon rotation of the rotor in a direction similar to that of the blade toward a high pitch position has resilient means interconnecting each blade and associated flyweight which biases the blade toward the high pitch position and resilient means connected with the flyweights to oppose their movement under the action of centrifugal force. The rotor of a wind motor comprises a hub 20 in which are pivotably mounted the aerofoil section blades 31 by ball bearings 30. A retainer 50 is attached to the root of each blade by a nut 40 and relative movement between the blade and retainer is prevented by tangs 57. One end of a torsion spring 55 located in a groove 51 of the retainer is passed through wall 58 and the other end is attached to a flyweight 65, Fig. 4. Each flyweight is mounted by a ball bearing 62 in the retainer 50 and carries a pair of pins 66, 67. The pins 66 abut against the output shaft 25 and the pins 67 project into the cut-away portion of the wall 52, Fig. 6, of the retainer 50. The pins 67 are also engaged by a pair of links 70 which are pivotally connected to a collar 73 slidable on the shaft 25. The collar 73 is urged to the left by a spring 74. When the rotor is stationary, the pins 67 engage the shoulder 53, Fig. 6, and the pins 66 engage the shaft 25 and the blades are set to a high pitch stop position of approximately 75 degrees. When the rotor starts to rotate, the forces on the blades rotate the retainers 50 until the shoulders 54, Fig. 4, engage the pins 67. In this position the opposed forces of the governor spring 74 and the centrifugal twisting moments on the blades are in equilibrium with the centrifugal force on the flyweights and the aerodynamic twisting moment on the blades. The flyweights then govern the speed of the rotor. A pin 80 coacts with surfaces 82, 83 to limit the movement of the blade. In a modification the torsion spring 55 is replaced by a coiled tension spring and the flyweights in the form of a major segment of a cylinder having an arm which engages the shaft 25. This arm enables the pin 66 to be dispensed with. The governor spring 74 may be replaced by a pair of coaxial springs.

Title: Improvements relating to drop-down breech loading small arms
IPC: F41A19/54
Filed: 1931-03-19
Abstract: 372,035. Drop-down guns. SMITH, E., 11A, St. Mary's Row, Birmingham. March 19, 1931, No. 8416. [Class 119.] Relates to drop-down breech-loading guns of the type in which the barrels automatically drop into the open position when the locking means therefor is released. According to the invention, the mainspring 8, Figs. 2 and 3, is mounted within a pivoted member 9 in such a manner that the spring is stressed only during the closing movement of the barrels. The member 9 is pivoted at 10 and is formed with a projection 9c which co-operates with the knuckle 11a of the fore-end 11b. A nose 9b of the member 9 normally rests beneath the nose 5b of the hammer 5. By the engagement of the projection 9c within the knuckle 11a, the member 9 is rotated during the breaking of the barrels and its nose 9b rocks the hammer 5 until the latter is engaged by its sear 6. The mainspring 8 moves bodily with the member 9 and is not stressed. During the closing movement of the barrels, the lower arm of the spring bears against the nose 5b of the hammer and the spring is thereby stressed. A spring 14 tends to retain the member 9 in the position shown in Fig. 3 and thereby to bring the projection 9c to a convenient position for engagement with the fore-end during the assembly of the barrel, or barrels, with the stock. In a modification, the barrels, in the closed position, bear against an upward extension of the rear end 9a of the member 9, to affect a slight further compression of the mainspring.

Title: A numeral storing device for electro-mechanically operated book-keeping, calculating or the like machines
Filed: 1955-03-24
Abstract: 788,071. Mechanical digital data storage apparatus. TRIUMPH WERKE NUERNBERG AKT.-GES. March 24, 1955 [July 31, 1954], No. 8546/55. Class 106 (1). In a number-storage device wherein resilient settable digit - representing teeth 17 of a group of comb - shaped plates 18 (one only shown) are sensed and reset in denominational succession under the control of cams on a step-wise rotatable shaft 2, the notched latching plates 7 adapted to hold the teeth 17 in their alternative positions of lateral adjustment are laterally displaceable on their pivot shafts 13 in order to move the teeth laterally into the path of sensing bars 20. By this means the use of coupling bars between the teeth 17 and sensing bars 20 is avoided. The plates 7 each have a long arm 9 and a short arm 8 engageable by respective cams 6 and 5 on the shaft 2. During each step rotation of the shaft 2, the cam 6 in the denomination concerned first displaces its associated plate 7 laterally (see intermediate plate, Fig. 3) to position the tooth 17 for sensing, after which the cam 5, associated with the next denomination engages over the arm 8 to unlatch the next plate 7 momentarily (Fig. 6) and so enable the tooth 17 to be reset according to a new digit value, by energization (or not) of a relay 19 which rocks the comb plate shaft 18 between small limits. A spring 12 returns the plate 7 after actuation by the cams 6 and 5.

Title: Improved process and apparatus for the cracking or the destructive hydrogenation of oils, or suspensions of coal in oil
IPC: C10G1/06
Filed: 1929-03-16
Abstract: 330,025. Hunter, T. G., and Imperial Chemical Industries, Ltd. March 16, 1929. Hydrogenation, destructive; hydrocarbons, cracking.-In a process for the destructive hydro. genation or cracking of oils or suspensions of coal in oils with or without a catalyst, the material is caused to pass,by means of the injector action of a gas, through heated vertical tubes and is projected against a baffle which causes it to fall back in the form of a parabolic curtain, through which the gases and vapours must pass. The pressures employed range from one to 300 atmospheres or more, hydrogen at high pressure, being used for destructive hydrogenation, and carbon dioxide or nitrogen for the injector action during cracking. In the apparatus shown, fresh material is furnished by the supply pipe 14 of a pump 7 and is forced up tubes 2 by hydrogen or other gas under pressure, entering by a pipe 8, which by injector action carries the material to be treated up the tubes 2. Situated above the tubes 2 is a baffle plate having a concave base 4<a> and a central conical portion 4 which causes the material impinging thereon to fall as a parabolic curtain and be returned to the pipe 14 by a pipe 6. Hydrogen may enter the upper part 3 of the apparatus by a pipe 8<a>. Heated gases are sup-, plied to the chamber by a pipe 9 at a pressure approximately the same as that of the hydrogen or other gas. Vapours and gases-pass off by a pipe 11 to a catchpot 12, any separated liquid being returned by a pipe 13 to the supply pipe 14. A valved purge 15 for solid matter is provided at the lower part of the chamber 3. The temperatures employed vary from 400‹ to 500‹ C., and the tubes and other pressure resisting parts may be constructed of mild steel having an iron sheath or of an alloy steel such as a nickel, chromium, molybdenum steel. The catalyst may consists of ferric oxide in a fine state of division or the tubes 2 may be coated with a metallic catalyst.

Title: An improved device for the release of clockwork and like intermittently released driving mechanism
IPC: G04C13/14
Filed: 1942-06-23
Abstract: 558,322. Clocks. LANDIS & GYR SOC. ANON. June 23, 1942, No. 8580. Convention date, June 28, 1941. [Class 139] In a clockwork or like mechanism with intermittent or periodic release means for the driving mechanism a device is provided for absorbing any additional or abnormal driving moment the device comprising two coaxial ratchet wheels with oppositely arranged teeth connected by a resiliently member which tends to hold the wheels in a definite angular position and engaged by pawls integrally connected. The minute shaft 4 is driven from a spring drum 6 through gearing 5. The gearing 5 also drives through a gear 7 a shaft 8 on which is fixed an excapement wheel 9 and mounted loosely a similar wheel 10 with the teeth inclined in the opposite direction. A rod 11 fixed to the wheel 9 extends through a slot 12 in the wheel 10 and a similar rod 13 fixed to the wheel 10 extends through a slot 14 in the wheel 9. The rods 11, 13 are spread apart to the limit of the slots by spring 15, so that the wheels 9, 10 are at an angular position relatively. Pawls 16, 17 rigid with a shaft 18 engage the wheels 9, 10 so that when pawl 16 rides upon the circular peripheral part of the tooth, the pawl 17 engages a tooth space. A gear wheel 19 in one with the wheel 10 drives a shaft 23 through gears 20, 21, 22. The shaft 23 carries the disc 24 of an electromagnetic brake and also an escapement arm 25. Coacting with the arm 25 is the abutment arm 26 of a four-arm oscillating lever 26, 27, 28, 29 turning about a shaft 30 and through a pin 31 on arm 29 controlling the spring arms 32, 33 of the armature 34 of an escapement relay having coils 35, 36. A pin 37 on wheel 21 coacts with the arm 27 and with the inclined face 28a of the arm 28. If the normal driving moment acting on the hands 2, 3 actuate the relay 34, 36, the armature 34 tilts towards coil 35 and spring 33 strike the pin 31 and releases arm 25 bringing arm 28 with part 28a into path of pin 37. The spring 6 now turns the hands 2, 3, the pawl 17 rises on to the peripheral part of the next tooth while pawl 16 slides into the next space. During this movement, the arm 25 has made a few revolutions and the pin 37 has moved against 28a moving it to one side and oscillating the lever 26-29 back, the arm 26 locking the arm 25. Further action of the relay tilts the armature 34 towards coil 36, rocking arm 27 into the path of pin 37, the lever 26-29 being restored at completion of the revolution of 21. If an additional driving moment due to wind pressure on the hands acts, the only effect is to move wheels 9, 10 relatively and stress spring 15 further.
