Title: Improvements relating to the coupling of the line space ratchet wheel of a typewriting machine
IPC: B41J11/24
Filed: 1921-05-02
Abstract: 173,484. Sßndor, F. Dec. 29, 1920, [Convention date]. Platen-roller couplings.-A coupling is provided with a releasing-member consisting of a sleeve 1 which is formed with a tooth 4, Fig. 3, entering a recess 5 in a stationary bush 7, and is adapted, on being turned, to move axially and release or restore the coupling, a spring catch preventing accidental movement of a sleeve when it has been turned to carry the tooth out of the recess. The sleeve is provided with a hand-lever 3 or is formed as a thumb-wheel. The coupling may consist of a number of blades 14 mounted in a casing 12 on the platen shaft 2 and engaged by a coned sleeve 10 which is forced outwards by a spring 9, a weaker spring 11 being interposed between the sleeves 1, 10. The linespacing pawl engages external teeth on an annulus 21 which is mounted loosely on the casing and is formed at the sides with internal teeth 20 engaging the forked ends of the blades. Each blade carries a pin 18 which is forced by a spring 17 into engagement with a groove 25 between the teeth 20. Normally the tooth 4 is in engagement with the recess 5 and the sleeve 1 permits the sleeve 10 to hold the blades 14 in engagement with the annulus. On rocking the hand-lever, the coned sleeve is forced backwards and the springs 17 release the blades.

Title: Wind turbine
IPC: F03D1/06
Filed: 1924-12-15
Abstract: 250,636. Mann, V. Dec. 15, 1924. Regulating.-A wind-motor for utilizing the Magnus effect comprises rotatable cylinders 1, or other figures of revolution, which are radially arranged in a wheel 30, and are rotated by the relative rotation of the wheel 30 and a concentric bevel-wheel 7 gearing with the cylinders 1. To start the motor, the wheel 7 can be rotated through gearing 20 - - 26 from a handle 27 or a motor, when the wheel 30 is revolving, the shaft can be locked by a bolt 29. The wheel 30 drives, a power-shaft 19, which can be made to drive the bevel-wheel 7 to increase the speed of rotation of the cylinders 1 through gearing 38 - - 35, Fig. 3, a clutch 40, shaft 83, variable belt gearing 32, 33, 34, a clutch 82, and the gearing 26 - - 20. In this modification, the handle 27 may be arranged as shown to drive the shaft 83 through a clutch 39. which is linked to the clutch 40 for simultaneous operation. The wind-wheel may be stopped by turning it out of the wind, or by stopping the rotation of the cylinders 1; the latter may be done by rotating the wheel 7 in the same direction as the wheel 30, and if this rotation is effected at a speed greater than that of the wheel 30, a braking-effect is produced. To reverse the rotation of the wheel 7, the clutch 82 is shifted so that the shaft 26 is driven either from the shaft 19 or the starting means through the crossed belt 81. For varying the drive from the shaft 19 the belt 34 may be shifted through a relay from the governor driven from the shaft 19. In one relay, the governor operates a control piston for the admission of pressure fluid to a servo-motor, the piston-rod of which is linkconnected to the belt-shifting lever. In an electric relay, the governor controls the direction of drive, and the speed, of a motor 68, Fig. 10, which operates a screw-and-nut device 69, 70, 61 to move the belt-shifting lever 63. This screw- and nut device may also be used for hand-control. The arms of the wheel are shaped so as to assist in the rotation thereof and are directly behind the cylinders. Reference has been directed by the Comptroller to Specification 243,756.
Patent GB-465796-A (GB)
Title: Improved means for forming and delivering a suspension of cementitious material in air
IPC: E04F21/12
Filed: 1935-11-11
Abstract: 465,796. Cement guns. WESTBERG, G. E., and WESTBERG, H. R. A. Nov. 11, 1935, No. 31124. [Class 20 (ii)] Cementitious material is fed in measured quantities from a hopper by means of a rotary valve device to a dispersion chamber where it is met by a current of pressure air directed across the path of the material whereby it becomes dispersed and suspended in the air, the air and suspended material being subsequently fed by combined mechanical means and air pressure to a nozzle where it is hydrated and discharged. A machine for carrying out this process comprises a frame 10 with uprights 13, 14, on which are mounted a power unit 16 and a hopper and valve feed device 47, 51 respectively. The motor 16 drives a longitudinal shaft 24 through chain gearing 22 and this shaft drives a shaft 28 through spur gearing 27. The shaft 28 through spur gearing 31, 32 drives a rotary valve 51 and the shaft 24 through chain gearing 103 drives a mechanical feed device 87 disposed beneath the dispersion chamber 80. The rotary valve 51 is adjustably mounted within a casing 40 at the outlet to the hopper and comprises tangentially arranged pockets 63 which convey the material in measured quantities trom the hopper to the entrance 55 of the dispersion chamber. The valve is mounted to rotate in its casing in an airtight manner by means of rubber sheeting 71 and loose sand and cement packing, thus preventing the dispersion pressure air from escaping to the hopper through the valve ; vents- 111, Fig. 4, are provided to release the air-pressure from the emptied pockets as they rotate towards the filling position.. Pressure air is supplied through a tube 85 to a domed head 84 at the side of the dispersion chamber 80, so that this air is made turbulent and passes across the path of the material supplied 'to the chamber from the rotary valve 51. A suspension of the material in the pressure air is thus formed and the mixture then passes to a mechanical screw-feed device 86 which is mounted on a sleeve 87 through which extra pressure air may pass from a source 110. This extra pressure air is adapted to escape through divergent apertures 91 provided in the head 90 of a stirring device 93, which is positioned at the front end of the sleeve 87, a central passage 92 being also provided to allow extra pressure air to eject the material into the tube 99 leading to a nozzle 100. The nozzle tapers from the rear to the forward end and hydrating water is supplied to it through a valve controlled tube 101. The rates of rotation of the valve and screw-feed devices are so adjusted that the feed will be uniform and the suspension of the material in the pressure air maintained.

Title: Apparatus for the bulk handling of cigarettes or other rod-like articles
IPC: A24C5/356
Filed: 1960-09-12
Abstract: 921,831. Dispensing rod-like articles. K. KÍRBER. Sept. 12, 1960 [Dec. 22, 1959], No. 31334/60. Class 78 (1). A device whereby cigarettes Z or like articles contained in a tray 48 may be dispensed into a magazine 4 consists of a tray holder such as the angle frame 25, means for raising and inverting the holder to a discharging position above the magazine, and a slidable tray cover 28 carried by the holder, the cover being automatically suddenly removed from the tray on the attainment of the holder's discharging position and automatically returned to close the tray during the holder's subsequent lowering. The cover 28 is fitted with pins 27, 29 which slide in a slot in a plate 9 carried by the holder, the pin 27 also sliding in a slot 26 in a lever 17 which is pivoted to the plate 9 at 16. The lever 17 is normally prevented from turning by the engagement of a pawl 39 carried thereby with a notch 40 in one arm of a lever 41 pivoted to the plate 9 at 44. From the initial position (Fig. 1), the holder is raised by turning about fixed pivot 8 and, as the discharging position is approached, the end 49 of cover 28 strikes a lever 33 mounted on a pivot axis 34 fixed above the magazine. The pawl 39 and notch 40 holding the cover closed, the holder continues to move against the spring 35, biasing the lever 33, until the end 42 of lever 41 strikes stop 43. When this occurs, lever 17 is released and a spring 20, assisted by the spring 35, quickly opens the cover 28. During lowering, a roller 14 whose axis is fixed closes the cover and springs 35 and 46 act on levers 33 and 41 respectively to reset the pawl 39 in its notch 40.

Title: Fuel injection systems
IPC: F02D41/18
Filed: 1972-07-05
Abstract: 1365270 Spray carburetters ROBERT BOSCH GmbH 5 July 1972 [5 July 1971] 31347/72 Addition to 1283860 Heading F1B A fuel injection system for mixture compressing I.C. engines having continuous injection into the intake manifold and separate ignition as claimed in Claim 1 of Specification 1283860 is modified in that the return force is provided by hydraulic pressure which is determined by a spring in a pressure regulating valve, the prestress of the spring being variable by means of the electromagnet. This flow into the intake manifold 1, 4, 5 moves the measuring element 2 about its pivot 9 and hence the fuel distributing valve spool 11. Fuel from the feed line 18 is tapped off by a branch pipe 32 via a throttle 34 and a further throttle 57 and enters a chamber 33 where it acts on the end surface 12 of the spool. A passage 35 leads from the space between the two throttles to a diaphragm type pressure regulating valve 36. The valve comprises a diaphragm 24 and a valve seat 40, movement of the diaphragm away from the seat creating an annular cross-section for fuel flow to a pipe 37 which leads back to the fuel tank 17. The diaphragm is pressed against the seat by a spring 43, which abuts an adjusting screw 44 and is contained within a core 46 which carries a coil 51. Interposed between the diaphragm and the spring is an armature 47 which is carried by a spider support 52. A ring 56 closes the magnetic circuit. Current fed to the coil 51 creates a magnetic field which opposes the spring force, reduces the pressure in chamber 33 and results in enrichment of the fuel/air mixture supplied to the engine. The current supplied to the coil through the socket 55 is varied in accordance with the angular position of the throttle valve, to the shaft of which is attached a slider 65. The slider engages a series of segments which through resistors 70, 71, 72 vary the potential on the base of an emitter-follower connected transistor 77 controlling the current flow through the coil 51. The resistor 70 is variable and enables the idling mixture to be adjusted. An NTC resistor 73 enriches the mixture when the engine is cold. A signal U ST  corresponding to other engine characteristics or to atmospheric pressure for altitude correction may be added. An RC circuit in series with a resistor 63 enriches the fuel-air mixture during starting and the first twenty seconds of running.

[Class 98 (i) ] In a photographic camera in which the shutter speed setting is governed by a light-sensitive cell which controls the deflection of a pointer constituting a stop for an element associated with the shutter mechanism, a light reflecting member 16 is positioned to receive light through the camera objective 10 and to reflect it on to the light-sensitive cell 17, and means provided for holding the pointer 34 in its deflected position are so coupled with the light deflecting member 16 that the latter is moved out of the path of the light rays substantially at the same time as the pointer 34 is blocked in its deflected position. Preferably, the means for holding the pointer comprise a pivotally mounted comb member 35, which is held clear of the pointer by a lever 37 when the roller-blind shutter, which is of the kind described in Specification 520,957, is fully wound. The camera is pointed towards the object to be photographed, and light entering the lens 10 is reflected by the mirror 16 on to the light-sensitive cell 17, which controls the pointer 34. When the shutter is released, the first blind moves, and lever 37 moves to allow the comb 35 to entrap the pointer. Mirror 16 is pivoted at 18 and connected by a link 89 to the comb 35 so that at the same time it is moved out of the light path by action of a spring 88.

Abstract: 641,193. Washing-machines. BENDIX HOME APPLIANCES, Inc. Dec. 4,1947, No. 32062. Convention date, March 4, 1946. [Class 138 (ii)] A water inlet for a washing-machine for preventing reverse flow comprises a pair of conduits extending into a tub 10 and branching from a common inlet; the conduits extend in the same general direction but have outlets directing fluid in different directions relative to the direction of rotation of a clothes receptacle 11 in the tub so that the flow in each induced by rotation of the receptacle is unequal. As shown in Fig. 1, water is supplied to the tub 10 by a pipe 21; the water jumps a gap and passes under a lip 28 into an outlet 25 attached to the inside of the tub at the top. This outlet 25, Fig. 3, has two conduits 26, 27 divided by a baffle 29, Fig. 1. One conduit 26 is substantially parallel to the axis of rotation of the clothes receptacle, the other 27 is curved so that the water from it meets that from the outlet 26 adjacent the end of the outlet 26. The outlet from conduit 27 is in the direction of rotation of the receptacle and this causes the receptacle to induce a flow in conduit 27 so that the flow in this conduit is different from that in conduit 26; any back-flow of suds into conduit 26 will therefore tend to be returned through conduit 27.

Abstract: 451,766. Cathode-ray tubes; photoelectric cells. BROADWAY, L. F., Strathmore, Park Way, Hillingdon, Middlesex. Nov. 8, 1934, No. 32181. [Class 39 (i)] An electrostatic electron lens comprises two apertured electrodes between which a focusing field is maintained, and in at least one electrode, the surface bounding the part of the aperture facing the co-operating electrode is so shaped that at any point in this part the field component perpendicular to the axis is proportional to the distance from the axis. This is stated to give perfect focusing. It is shown mathematically that in the absence of disturbing fields axial sections of the surface are hyperbolas, having an angle of 70‹ 321 between the asymptotes. Fig. 8 shows a lens system constituted by electrodes 6, 7 of hyperbolic section, together with a remote first anode 8 having a diaphragm 21 and a cathode 4 and shield 5 of hyperboloidal or frusto-conical shape. A single electrode 9, Fig. 5, may consist of diaphragms 11, 12 constituted by conical frusta having semi-vertical angles 54‹ 44<1>, or the surfaces 11, 12 may be rounded to approximate hyperboloids. In modifications, annular diaphragms, the inner edges of which lie on a hyperboloid, may be mounted in a cylinder or two curved conical frusta may lie one at each side of a central diaphragm or two conical frusta may be joined by a cylindrical member having a central diaphragm. The invention is applicable to devices in which electrons from a photo-electric surface are focused onto a mosaic screen. Lenses analogous to optical cylindrical lenses may be constructed. Specification 431,327 is referred to.
