Title: Improvements in or relating to control apparatus for looms with automatic stop mechanism and the like
IPC: D03D51/34
Filed: 1933-05-11
Abstract: 406,160. Electric stop-motions &c. for shuttleless looms. TEFAG TEXTIL FINANZ AKT.-GES., Zurich, Switzerland.- (Assignees of Wuttig, E. ; 41, Schulstrasse, Chemnitz, Germany.) May 11, 1933, No. 13782. Convention date, May 23, 1932. [Classes 142 (i) and 142 (ii).] Relates to stopmotions or alarms, or both for looms employing shuttles of the gripper or nipper type. Circuits dependent on different factors such as the condition of a thread or of a part of the loom for operating indicating means or stopping the loom, or both, are each controlled by two switches in series, one an operating-switch, being controlled by the thread or part of the loom, while the other, a timing-switch, is mounted with the timing-switches for the other circuits on a common carrier, such as a rotating cylinder or disc, provided with spaced contact-making members adapted to close the timing-switches at those times when the operating-switches are normally open, but to complete the circuit to stop the loom when an operating-switch is closed. The cylinder 1, Fig. 1, carries timing-contacts 3<a> .. 3f adapted periodically to put a battery 4, and a solenoid 9, in circuit with an indicator 6<a> ... 6f and a corresponding operating-switch 8<a> . . 8f so that no current flows from the battery except when the timing and operating switches are closed simultaneously to stop the loom through the solenoid 9 and to operate the indicator. One of the operating-switches, shown diagrammatically in Fig. 1, corresponds to a feeler 19, Fig. 2, between the feeding point for the weft and the point at which the gripper shuttle 14 picks up the weft. When the weft breaks or has insufficient tension, the feeler allows the circuit to be completed. An operating-switch in the form of a feeler 21, 21, Fig. 3, is arranged between the selvage and a clip 20 for holding the cut weft end 16 prior to bending-in of the weft. If the weft is broken or has insufficient tension, the feeler closes the switch 21, 22 corresponding to one of the operating-switches shown in Fig. 1. A further operating-switch comprises the parts 24, 25, 26, Fig. 4, of the stationary shuttle box 23. If the nipper shuttle 14 fails to enter the box, the switch remains closed. If the heald 27, Fig. 5, fails to function correctly, a projection 28 remains between members 29, 30, and the switch remains closed. In order to prevent fouling of the hammers 31, Fig. 6, for supplying weft of the correct colour to the nipper shuttles, each hammer in its raised position is adapted to close an operating-switch 33, 34, 35. If the hammer fails to return to the position shown in dotted lines, the loom is stopped and an indicator is operated when the corresponding timing-switch is closed. A further circuit may be dependent on the condition of the warp threads, a broken warp thread or one under insufficient tension allowing a contact bar or a heddle to fall and close the corresponding operating-switch.

Abstract: 944,728. Photographic recording cameras. TEKTRONIX Inc. April 17,1961 [Dec. 29, 1960], No. 13817/61. Heading G2A. A photographic camera apparatus has an object plane, an image plane, a lens structure and a pair of stop members positioned on the lens structure so as to provide an object reference surface and an image reference surface thereon, said apparatus also having means for holding the lens structure with the object reference surface a constant distance from the object plane and the image reference surface a constant distance from the image plane while allowing the distance between the object reference surface and the image reference surface to vary in order to accommodate different lens structures, the reference planes being in fixed axial positions on the lens structure so as to provide a preset magnification by the lens structure between the image plane and the object plane with the object plane focused on the image plane. As shown, an oscilloscope camera comprises a film holder 24 providing an image plane 66 at which film 62 is supported, a lens structure 20 rigidly but releasably mounted by means of a collar 76 and a housing member 80 to the film holder 24, a housing 36 rigidly connected by way of threaded coupling members 42, 94, 90 to the housing member 80 with a collar 86 of the lens structure firmly abutting against a surface 52 of the housing 36, an apertured camera support plate 26 which is connected to two rods 40 slidably mounted in the housing 36 as shown in Fig. 5 and which is mounted in a recess 35 of the housing 36 for fine focusing adjustment by means of a knob 46 and finally an apertured mounting plate 12 which may be secured for example to a C.R.O. tube and which is connected to plate 26 by way of hinges 28 so that after release of a catch 30 the bulk of the camera may be swung away from the plate 12 and detached therefrom. After the camera has once been focused to bring the face of the C.R.O. tube into coincidence with the object plane 50 by rotating knob 46, the lens structure 20 may be replaced without need for further focusing by a similar structure having collars 76 and 86 preset in positions to give a different magnification. The camera also includes means for viewing the C.R.O. tube, said means comprising a beamsplitting mirror 54 inclined at 45 degrees, a fully reflecting mirror 57 in a light-tight viewing hood 14 which is also provided with a pivotable shutter 58. A graticule 104, illuminated by lamps 106 adjustable as to intensity by a knob 110, is provided at such a position as to produce an image apparently coincident with the object plane 50, thereby avoiding parallax. The camera also includes a mask slide 100, a shutter unit 70 and leg supports 118 and 116.

Abstract: 907,732. Registered colour photographic composite prints. THIEMIG, K., and THIEMIG, G., [trading as THIEMIG GRAPHISCHE KUNSTANSTALT UND BUCHDRUCKEREI KOMM.-GES., KARL]. April 20, 1960 [June 10, 1959], No. 13818/60. Class 98 (2). To make prints, particularly for use in prospectus or catalogue work in photogravure, as of the two female figures of Fig. 1 which are understood to be in colour and are to be overlapped as in Fig. 8 without cutting out and matching operations with the various colour records, four separations of each figure are first produced on film, one from each set is picked out, preferably those having widely different density in the overlapping areas, each may be roughly cut away as in Fig. 2 before bringing together as in Figs. 3, 4 to form a negative montage which is printed on to a photographic plate, known as the reference plate, and which shows the overlapping outlines of the two colour sets. A transparent film is then fixed on this reference plate and on it the left-hand female figure and the overlapping areas are separated by covering the remaining areas with opaque ink and the result optically printed to form a mask of the left figure and its overlapping areas in transparent outline. A contact print of this mask is then made and registered with the reference plate for production of a second outline mask, that of the right-hand figure, but omitting the overlapped areas. A first colour separation, say that of the left-hand figure, is then registered with the left-hand mask and exposed on to film, separation and mask are removed and replaced by the corresponding separation and the mask of the right-hand figure in position registered to that of the lefthand assembly, and the film is exposed again and finally processed to give a positive separation in which the two figures are merged. The other separations of the set are produced similarly. Figs. 9, 10 not shown are concerned with a device having pin and perforating arrangements for effecting the double form of registration indicated.

Abstract: 965,736. Master cylinders. KELSEY HAYES CO. April 8, 1963 [May 7, 1962], No. 13938/63. Heading F2F. A master cylinder comprises tandem main and floating pistons 12, 30 forming two large working chambers 55, 17 and a third small annular chamber 38, of which chamber 55 is connected to the front wheel brakes 74 and chambers 17, 38 are initially connected to the rear wheel brakes 41, but upon the pressure in the system rising to a predetermined value chamber 17 is cut off to give a more rapid increase of pressure in the front brakes. As shown, communication between chambers 17 and 38 is controlled by a longitudinal valve 45 disposed in axial bores in pistons 12, 30 and normally held clear of a seating in piston 30 by a loading spring 49, but in a second arrangement, Fig. 3 (not shown), the valve is mounted laterally of the pistons. Upon initial movement of a push rod 13 a replenishing valve 65 is closed and brakes 74, 41 are respectively supplied from chamber 55 and chambers 17, 38 until the pressure rises sufficiently to close valve 45 against spring 49, when chamber 17 is cut off and the rear brakes are then supplied from the small chamber 38 only, resulting in a rapid rise of pressure in the front brakes. In the event of a sudden brake application causing premature closing of valve 45, the high pressure generated in chamber 17, assisted by spring 49, will re-open the valve to restore normal operation.

Filed: 1929-05-06
Abstract: 311,233. Neiss, H. May 7, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Sound-reproducing apparatus associated with kinematographs.-To obtain synchronized reproduction of sound and pictures the sound is recorded on a gramophone disc and also simultaneously on the picture film or on a film running therewith and the sound record on the film is employed to control the drives of the gramophone disc and the picture to secure synchronism. Fig. 2 shows the reproducing apparatus wherein the picture record 6 and sound record 7 are driven by a motor 13 and the sound disc record by a motor 21 and current fluctuations due to the two sound records are led to a relay 17. When these fluctuations are synchronized in the relay the motors are not influenced by the relay and drive the picture and sound record in synchronism, but if the two sound films run out of synchronism the relay is unbalanced and acts on the motor circuits to restore synchronism.

Filed: 1943-08-27
Abstract: 585,667. Valve amplifying circuits. PATELHOLD PATENTVERWERTUNGS- & ELEKTROHOLDING AKT.-GES. Aug. 27, 1943, No. 14049. Convention date, July 17, 1942. [Class 40 (v)] In an amplifier having in its output at least two successive longitudinal resistances separated by a transverse resistance current feedback in regenerative sense is taken from impedances connected in each of the longitudinal branches so as to render the gain independent of both the load and the frequency. Fig. 1 shows an amplifier I, feeding a transformer II shown by its equivalent circuit and feeding a load III, transformers or other phase reversing devices being included between the feed-back impedances R3, R4 and the input, if necessary, to ensure appropriate phasing. By proportioning the impedance R3 in dependence of the valve impedance and the impedance due to the resistance and leakage inductance of the transformer-primary winding and the amplification factor of the valve, the effective internal resistance of the amplifier may be rendered zero, and in the same manner by proportioning the impedance R4 in dependance on the constants of the transformer secondary winding and its ratio together with the amplification factor of the valve the frequency response can also be corrected. The feed-back may be to the control grid of the valve as shown in Fig. 4, or one or both the feed-backs may be applied to the preceding stages. One or both the impedances from which the feed-back is taken may be variable. In a modification, Fig. 5, (not shown), transformers in the feed-back paths are avoided by feeding back to an appropriate preceding stage. Fig. 6 shows the application of a push-pull amplifier in which the feed-backs are applied to the grids of the valves 3, 4 through transformers from impedances R11, R12 in the transformer primary winding and impedances 13, 14 in the transformer secondary-winding.

Convention dates, Nov. 29, 1934 and April 27, 1935. [Class 108 (iii)] [See also Group XXVI] In a double-acting telescopic, piston-and-cylinder shock-absorber, liquid flows both during expansion and contraction of the device in the same direction through one or more restricting passages to a reservoir, the passage or passages being disposed in the upper end of the cylinder and provided with readily-accessible means of adjustment. As shown, the coaxial reservoir 3 and cylinder 5 are closed at their upper ends by a screwed plug 4 having restricting passages 24, 24<a>, Fig. 2, controlled by an annular valve 25 acted on by a Belleville washer 27 adjustable by a threaded ring 26, the passages communicating with the lower part of the reservoir 3 through one or more tubes 28 which prevent the liquid discharged from the passages mixing with the air in the upper part of the reservoir. In operation, on expansion of the shockabsorber liquid is forced directly by the piston 8 through the passages 24, 24<a> into the reservoir and is sucked into the cylinder from the reservoir through a non-return check valve 10, while on contraction, the valve 10 is closed and owing to the decrease in volume of the cylinder due to the entrance of the piston-rod 7, liquid is again forced through the restricting passages. In the latter case liquid flows also through valve-controlled orifices 12 in the piston which may be provided with supplementary orifices controlled by a spring-pressed annular valve, similar to the valve 25 and opening downwardly so as to damp small oscillations on expansion of the device. Liquid may be introduced into the shock-absorber by unscrewing the plug 4 or liquid under pressure may be injected through an orifice normally closed by a plug 30. The piston-rod 7, Fig. 2, is surrounded by a stuffing- box comprising flat annuli 20, 21 alternately of rubber &c. and metal and compressed by a spring 23. In a modification, Fig. 9, a rubber &c. ring 54 is pressed against the cover of the plug 4 by a metal ring 56 and against the piston-rod by a circular coil spring 58, the liquid scraped from the rod draining to the reservoir 3 through a conduit 59, annular channel 60, and conduit 61. A second, helically-divided packing ring 52 is mounted in a groove in a sleeve 51 which may be in two parts force-fitted after insertion of the ring 52 or which may be cut away to permit lateral insertion of the ring.

In use, fresh coffee powder is contained in the bottom cup 14c, once extracted powder in cup 14b, and twice extracted powder in cup 14a. Valves 8c and 11b are opened to allow extract in hopper 10b to flow into cup 14c and then closed, valves 8b and 11a are similarly opened and closed, and finally valves 8a and 16 are opened to feed water from the tank 2 into the top cup 14a and reclosed. The hydraulically operated pistons 7 are lowered to force the liquid in the cups 14a, 14b and 14c through the filters 13 and after raising again, cup 14a containing spent coffee powder is removed, cups 14b and 14c are moved up to the positions previously occupied by cups 14a and 14b, respectively, and a cup containing fresh coffee powder is inserted in the position previously occupied by cup 14c. This cycle is then repeated indefinitely. Each hopper 10a, 10b and 10c is heated by a water bath 15.
