Title: Method of and apparatus for dressing threads
IPC: D06B19/00
Filed: 1952-05-16
Abstract: 779,649. Coating threads; coating webs. SUCKER GES., GEB. May 16, 1952 [May 17, 1951], No. 12447/52. Class 140. A web 5 of woven fabric or of warp threads, to which a coating of heat-liquefied fat, wax or synthetic resin has been applied, is passed through molten metal 2 maintained at a temperature not below the melting point of the coating and to a depth that is adjustable according to the desired effect, and is cooled, e.g. by contact with a guide roller or bar 14, before winding up or passing to warp beams. As shown, the web passes around one or more guide rollers 3 immersed in the molten metal and mounted on a carrier 4 vertically adjustable by mechanical or hydraulic means 15. The heat-liquefied coating material may be applied by spraying, by rollers, or by passing the web vertically downwards through a column of the material floating on the molten metal and contained in a tube 6 of elongated rectangular cross-section. The material may be supplied to tube 6 from a heated storage vessel 9 through a pivoted pipe 10 having a valve 11. When the carrier 4 is raised out of the molten metal bath, a projection 16 thereon lifts out the tube 6 and rocks the pivoted pipe 10 to cut off the supply. In an alternative form the tube 6 is surmounted by a supply container which is in communication through a flexible pipe with a storage container that can be raised or lowered to lengthen or shorten the traverse of the web through the coating material.

Abstract: 723,772. Electron microscopes. SIEMENS & HALSKE AKT.-GES. May 31, 1951 [Oct. 14, 1948], No. 12956/51. Class 39 (1). Centering of the electron beam in an electron microscope is obtained by four deflecting arrangements, one pair of which adjusts the beam in one plane and the other pair in a plane at right angles to the first mentioned plane. Deflecting plates 71 ... 74, Fig. 7, are arranged between the gun and the objective and projecting lens, and are connected to adjustable tappings on potentiotransformer 75 through the smoothing circuit 78 and rectifiers 76, 77. The tappings 86...90 are operated by the two adjustable devices 91, 92. Additional adjustment is provided by variable resistances 93 ... 96. A condenser consists of two windings 41, 42, Fig. 4, and the poles 43, 45 which are separated by a non-magnetic ring 44 and an apertured diaphragm. A holder for each pair of electromagnetic coils is fixed by a screw thread to the poles which are assembled within the electron microscope by a bayonet joint so that wire connections for the coils are connected through clips to leading-in wires 50 which are sealed by a rubber disc 53, plate 54 and a. threaded ring 55 which is screwed to the container 56. A unit which contains only one pair of deflecting plates is substituted when the electron image is reflected from the object.

Title: Improvements relating to electric switches
IPC: G04F3/02
Filed: 1957-04-24
Abstract: 859,124. Retractive switches. HOLZER, W. April 24, 1957 [April 27, 1956], No. 13010/57. Class 38 (5). In a process timing switch controlled by an oscillating brake, the oscillating brake has its own drive and its rate of oscillation is determined by an eddy current brake. The oscillating brake is preferably driven by an auxiliary spring which is tensioned simultaneously with the spring driving the timing switch. As shown, rotation of the knob causes the spring 2 to be wound up, the contacts 10 to be actuated through the shaft 3 and cams 8 and 9 and the auxiliary spring 7 to be wound up by the ratchet and pawl 5, 6. Release of the knob 1 allows the spring 7 to drive the shaft 25, at a speed determined by the resistance of the eddy current brake circuit, so that the eccentric 29 on the shaft oscillates a rod 16 carrying stops 15, 18. This movement allows stepwise rotation of the ratchet wheel 13 and therefore stepwise rotation of the shaft 25 carrying the cams 8, 9. Resistances 28 may be switched into the brake circuit by cam-switches on the shaft 3.

Abstract: 816,866. Wrapping-machines. FORSTERS MACHINE CO. Ltd. April 30, 1957 [April 30, 1956], No. 13231/56. Class 94(1). The upper and lower side ears 3, 4, Fig. 1, of a package are folded down and up respectively by vertically moving plates 18, 31, Fig. 2, which fold the ears against thin plates 12, 28, Fig. 3, between which the packages are pushed by members 6 propelled by projections 7 from an endless chain mounted beneath the slotted base plate 5. In the construction illustrated the folding plates 18, 31 rock in bearings 22, 39 and have enlargements near the bearings to hold the folded ears against the package. The folding arms 18, 31 are linked together so that they are operated simultaneously from a single pair of cams 49 adjustably mounted on the driving shaft 60 of the machine so that their effective dwell may be altered. Each arm 18, 31 is moved laterally as it swings by a follower 52, Fig. 6, mounted on the shaft 21 carrying the arm and held against a fixed cam 57 on the bearing 22 by a spring 53. The thin plates 12 have each a bent rearward extension 13 which guides the unfolded lower ear and are mounted at their forward ends where they carry bull-nosed projections 15 which effect the tuck shown between the ears 3, 4 at C in Fig. 1. The thin plates 28 are mounted by their upper edges for a L-shaped plate 27 supported from a bracket 26 and formed with a rounded leading edge. The initial fold illustrated at B in Fig. 1, is made as the projections 7 push the package from a roller track 9 against a vertical web in the gap 10, and the folded package ultimately passes between a pair of heating elements 37 by which the package is sealed.

Title: Process of manufacturing starch products
IPC: C08B30/12
Filed: 1934-05-03
Abstract: Starch or starch-containing raw materials are treated in the cold with a substantially neutral hypobromite solution or with reagents which react to form a substantially neutral hypobromite solution. The product is stated to form a paste of the nature of a salve-like gel and to give the characteristic reactions of pure starch with iodine or Fehling's solution.  Part of the hypobromite may be replaced by hypochlorite.  The gel-like paste may be peptised with small quantities of substances having an alkaline reaction, e.g. ammonia, borax or sodium bicarbonate, to a thinly liquid sol which does not gelatinise, and may be used for dressing and laundering purposes.  According to examples, (1) 1 kgm. potato or tapioca starch are mixed with 1400 c.c. water and 400 c.c. of N-sodium hypobromite solution added.  After half an hour, the starch is filtered, washed and dried in air; (2) 1 kgm. potato or tapioca starch are mixed with 1500 c.c. water and 100 c.c. each of N-hypobromite and N-hypochlorite solutions added.  The starch is then treated as in the first example. Specification 420,275 is referred to.

Abstract: 252,726. British Thomson-Houston Co., Ltd., (Assignees of Prince, D. C.). May 27, 1925, [Convention date]. Switching systems.- A sectionalized alternating-current circuit has pairs of oppositely-connected thermionic valves between the sections instead of the usual sectionalized switches, the power being transmitted through the valves. Means are provided for causing each of the electron discharge devices to be rendered non-conductive when the current transmitted therethrough is zero so that the line can be sectionalized withcut undesirabie fluctuations of current and voltage. As shown, the three-phase section 4, 8, 12 is connected to the next section 3, 7, 11 by pairs of reversely-connected valves 1, 2, 5, 6, 9, 10 in each phase, each with its own separate cathode supply and each with its grid connected to its plate through a resistance 19 - - 24. In order to sectionalize the line, the grids must be maintained at potentials which preclude the transmission of current when their cathodes are charged to a negative potential. These potentials are supplied from batteries 25 - - 30 through high-speed electromagnetic switches 31 - - 36 such as are described in Specification 125,279, [Class 38 (v), Electric switches &c.], the closure of which is controlled by a synchronous machine 37 which drives a distributing contact device with rotating arms 52, 53 to ensure that the grid potentials are applied only when no current is passing through the corresponding valve. A power directional relay 41 and a polarized relay 76 are connected in the control circuits and a double throw switch 42 is provided for connecting the switch-operating coils to the commutator of the machine.
