Title: Improvements in scouring and washing machines for textile materials
IPC: D06F15/00
Filed: 1922-03-09
Abstract: 196,767. Petrie & McNaught, Ltd., and Hall, H. March 9, 1922. Wool scouring and washing type.-In scouring and washing machines for textile materials, means having combined vertical and horizontal movements are provided for passing the materials through a tank, while possers or.squeezing-devices act on the goods during transit. The goods are delivered to a tank a by a conveyer b and are passed through the tank by arms r pivoted to a frame s, which is suspended from a fixed frame by links t, z and receives horizontal movement from an eccentric w through a rod y and the link z and vertical movement through rods x, z, rocking arms u, and the links t. The effect is that the arms r bear on the materials by their own weight during forward motion and are lifted therefrom during reverse motion. Cross-members v are attached to the arms r. Possers or squeezing- devices h are moved vertically by eccentrics m, o, rods n, p and rocking arms i, j, k, springs contained in casings q preventing undue pressure on the goods. Preferably several possers are arranged side by side across the width of the tank at each station. Each posser comprises a grid forming the bottom of a box-like frame hinged to the supporting-stem and having troughlike tops to prevent escape of oil. The amplitude of motion of the possers and of the horizontal and vertical movements of the frame s may be varied, for example, by providing a number of joint pin holes in the link z and rocking arm u so that the positions of the ends of the eccentric rod y, x may be varied.

IPC: B60T13/24
Filed: 1929-03-05
Abstract: 307,831. Bragg-Kliesrath Corporation, (Assignees of Sorensen, J.). March 14, 1928, [Convention date]. Fluidpressure.-Power brake mechanism for vehicles comprises a valve controlled actuator or cylinder, a power applying member or lever pivoted at a fixed point and connected to the actuator, a second lever or member pivoted to the power applying member and connected to the brakes and means for applying the physical force of the operator to the second member whereby this force reacts on a connection of the second member to the brakes to operate the power actuator through the valve mechanism. The arrangement is such that the pressure applied by the power actuator reacts upon the foot of the operator, the valve mechanism has a follow-up action and the operator can apply a direct effort to the brakes. The power applying lever 28 mounted on a fixed pivot 29 is connected by a cable &c. 27 to the piston of the brake cylinder or actuator and has secured to its upper end the valve casing 39. The lever is of channel section and has pivoted within it at 36 a lever 35 which is connected to the brakes by the link 38 pivoted at 37. An extension 59 of the valve rod 49 abuts on the lever 35. The valve rod also carries a pedal plate 55. The valve casing has connections 44, 45 and an aperture 47 leading respectively to the suction pipe of the vehicle engine, to the brake cylinder and to the atmosphere. The valve casing 39 extends through the vehicle dashboard. Fig. 3 shows the parts in the normal position in which the brake cylinder is connected to atmosphere through the aperture 47. If the pedal 55 is depressed and the brake piston is adjacent its stop, the lever 28 remains stationary and the lever 35 turns upon the pivot 36 and starts the application of the brakes through the link 38; the valve 53 then covers the aperture 47 and the valve 54 uncovers the aperture 44 as in Fig. 4 thus connecting the brake cylinder with the engine suction pipe whereby power is applied by the piston to the brakes through the lever 28, pivot 36 and link 38. If the movement of the pedal is stopped the continued movement of the lever 28 moves the valve casing sufficiently to re-close the aperture 44 and the brakes are held applied. The pressure felt by the operator indicates the pressure that is being applied to the brakes. The pedal may be depressed sufficiently to cause a boss 55<a> to contact with the valve casing and thus enable the operator to add his direct effort to the full power of the piston. If in starting an application of the brakes, the brake piston is not against its stop or if it takes less pressure to move the piston towards its stop than it does to overcome the resistance of the brakes, the lever 28 will be moved and power will be immediately applied by the brake piston to the brakes.

Title: Improvements in and relating to radio communication systems for the navigation of aircraft
IPC: G01S1/02
Filed: 1941-06-05
Abstract: 557,870. Automatic control systems. HUGHES & SON, Ltd., H., SPROULE, D. O., and HUGHES, A. J. June 5, 1941, No. 7135. [Class 38 (iv)] [Also in Group XL] A navigation system for landing aircraft comprises means on the ground for formulating a radiation pattern the intensity of which continuously and periodically fluctuates about the desired flight path as an axis, and means on the aircraft by which its position relatively to the path can be determined from the amplitude and phase of the received signal and indicated as horizontal and vertical departures from the flight path. A beam AB, Fig. 3, inclined to the flight path AC, is continuously stated about that path as an axis, and an additional signal is transmitted in definite time relationship with the relation of the beam, in order to provide a reference phase with which the phase of the received signal may be compared. This additional signal may be a frequency modulation of the same beam or a short pulse, omitted from a second transmitter when the beam is in its uppermost position, controlling a continuous time base. If the aircraft is on the path AC, no change in intensity due to each rotation of the beam will be detected, but if the aircraft flies along some other part the received signal will be modulated in amplitude to an extent determined by its distance from the axis AC, and the phase of this signal will be determined by the angular position of the aircraft with reference to the axis. The combined amplitude modulated and frequency modulated signal is received by a standard superhet receiver 51, 52, 53, the frequency modulated component passing through a limiter 54, discriminator 56, and amplifier 57 to provide a reference phase for the centre zero dynamometer instruments 58, 59. The amplitude modulated component, the amplitude and phase of which is determined by the position of the aircraft, passes through detector 55 and amplifier 61 to the other coils of the instruments 58, 59. By the use of a 90 degrees phase shifter 60, and a suitable choice of the relative phase shifts of the two branches of the circuit, the instruments 58, 59 can be arranged to indicate respectively deviations from the desired path to right or left, and up or down, and the extent of such deviations. The transmitter may comprise a reflector and antenna mounted obliquely on the spindle of a constant speed motor which also carries a rotary condenser controlling the frequency modulation, Fig. 6 (not shown). For automatic steering, the instruments 58, 59 may be replaced by two phase motors controlling the steering and elevator mechanism of the aircraft.

Title: A method for producing a rastered recording of a video signal obtained by photo-electrically scanning a continuous tone picture
IPC: H04N1/405
Filed: 1969-02-10
Abstract: 1,256,145. Facsimile apparatus. DR-ING RUDOLF HELL. 10 Feb., 1969 [22 Feb., 1968], No. 7159/69. Heading H4F. To produce a half-tone (rastered) recording of a video signal obtained by photo-electrically scanning a continuous tone picture original, a raster foil is photo-electrically scanned by a separate scanning head the resulting pulses being added to the video signal obtained by scanning the original, and the resulting video pulses are fed to a recording head via a threshold value circuit. The raster foil may comprise a vignetted raster in which the density of the blackness across each raster line decreases continuously from a maximum value along the axis of the line, or a sharply drawn raster which is arranged a distance in front of the separate scanning head so that when scanned its raster lines have effectively the same degree of unsharpness as the vignetting. To produce colour separations from a coloured original, each colour separation preferably has a different raster angle to avoid a noirÚ structure. An overdriven amplifier may be located between the threshold value circuit and the recording head. To test the rastered signals before recording, a cathode ray tube producing an electrostatic charge image may be arranged to display the signals.

Title: Improvements in sheet-feeding apparatus for wrapping machines
IPC: B65B41/04
Filed: 1925-10-09
Abstract: 269,467. Marks, E. C. R., (Package Machinery Co.). Oct. 9, 1925. Sheet-carriers; grippers.-Relates to wrapping machines in which the wrapper is positioned in the path of the article to be wrapped. According to the invention, the sheet is positioned by gripper devices reciprocable on guide members and actuated by flexible members connected to shafts positively rotated alternately in opposite directions. As shown, a gripper device 82 comprising fixed jaws 84 and movable jaws 86 is mounted on a carriage 88 adapted to reciprocate on horizontal guide bars 90. The movement is effected by sprocket chains 94 passing over wheels 96, 98 The shaft 100 of the wheel 96 is rotated alternately in opposite directions by crank-actuated rack-and-pinion mechanism in such a manner that the carriage 88 is reversed quickly at the receiving position on the left, and slows up tovards the point at which tha jaws are to be opened to release the wrapper, thus facilitating the correct positioning of the wrapper and allowing time for it to be removed to the folding-devices before the return movement. The jaw 86 is closed upon the jaw 84 at the receiving point by the action of a slide rod 142 frictionally mounted in the carriage 88 and moved relatively to the right by a stop 148, so that a roller 146 is moved into a notch 144, Fig. 4, in the rod by a spring 138, and the jaw thereby closed. At the other end of the travel of the carriage 88, a stop 150 acts reversely upon the rod and the jaws are opened, thus leaving the sheet supported by pronged bars 162, and the forward end aligned by stops 156 and curved springs 158 which prevent rebounding. Specification 269,246, [Class 94 (i), Packing &c.], is referred to.

Abstract: 840,220. Joint-making packing. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 15, 1958 [March 6, 1957], No. 7383/57. Class 122 (3). [Also in Groups XXV and XXVIII] A fluid-pressure seal comprises a unitary carrier member 8 provided with two coaxial grooves open in opposite directions or more than two grooves open alternately in opposite directions and resilient rings 10, 12 located in the grooves, the carrier being.capable, when the seal. is in position, of maintaining the rings in sealing contact by either exerting on them a spring-loading or by being permanently deformed. The rings 10, 12 are mounted in corrugations 9, 11 formed in the inner and outer surfaces of the member 8 which may be made from a springy. metal so that when the seal is mounted within a socket 15 on a pipe 14 and screwed down by a.plug 17, the rings are forced into sealing contact with the socket-and a pipe 13. When the member 8 is made of a deformable metal, the plug 17 may constitute a tool which, after deforming the member 8 so as to cause the rings to be forced into sealing contact, is removed from the socket 15. As applied to a double-ended pipe coupling shown in Fig. 6, the members 8 are mounted in recesses formed in a casing 22 and their outer ends are acted upon by curved surfaces formed in screwed caps 25, 26 which thereby force the rings 12 into contact with the recesses. The seal, in the form of a washer, may be applied to sealing a hexagonheaded screwed plug (Fig. 3, not shown). The member 8 may be suitably weakened or slit to facilitate its deformation or be of a thermoplastic material, its deformation being effected by the application of heat and pressure. Specification 818,819 is referred to.

Title: Time delay circuit with field effect transistor
IPC: H03K5/00
Filed: 1967-02-17
Abstract: 1,129,208. Transistor timing circuits. SQUARE D. CO. 17 Feb., 1967 [29 April, 1966], No. 7581/67. Heading H3T. A timer comprises a timing capacitor connected in parallel with an electronic switch to the gate of a field effect transistor, the timing period being determined by the time required after operation of the switch to charge the capacitor to a reference value at which the transistor conducts. When a negative voltage is applied to input terminal A a transistor T2 becomes non-conductive and so removes the short-circuit from a timing capacitor C. It accordingly charges until the voltage at the gate of transistor T6 exceeds the bias applied to the source from potentiometer R6, R7. Transistors T6 and T5 accordingly conduct and change-over the state of a bi-stable circuit T3, T4. When the voltage at A returns to zero T1 cuts off and this, via R12, restores the condition of the bistable circuit and via R10 renders T2 conducting to short-circuit the capacitor. The reset terminal enables the bi-stable circuit to be reset to avoid false operation when a signal is applied to A concurrently with switching on.
