Title: Improvements in or relating to processes for regulating the frequency of alternating current producers
IPC: H02J3/08
Filed: 1930-11-06
Abstract: 366,573. Automatic regulation. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Nov. 6, 1930, No. 33433. Convention date, April 8. Addition to 366,534. [Class 38 (iv).] In apparatus according to the parent Specification, for controlling frequency, a member the position of which depends upon the actual frequency co-operates with a counter member and the position of one selectively to the other is controlled by the difference between the actual and the standard number of alternations in a given time. As shown the frequency indicator 1 co-operates with a counter member 2 constructed as a contact partly, and the two are brought intermittently into contact by a drop-loop 5 to control a motor 13 governing the prime mover speed. A disc 27 with two contact segments is driven at a standard speed by a motor 33 and a disc 28 with a contact segment 31 is driven at a speed proportional to the actual frequency by a motor 34. A stationary track 32 completes the electrical connection between the segment 31 and one or other of the segments on the disc 27 at intervals of five minutes for example and for a time depending on the relative displacement of the discs, i.e. the difference between the actual and standard number of alternations in, say, five minutes. This electrical connection energizes one or other of two similar stays 25, 26. As a result the drop loop is lifted by deenergization of a magnet 5 at contact 35 or 36, a slow acting relay 29 is energized at contact 37 or 38, and a clutch 22 is de-energized at contacts 40 or 41 ; the frequency indicator 1 and contact path member 2 are thereby made free to take up their normal positions. After a short interval the relay 39 causes re-energization of the clutch 22 at contacts 43 and, at contacts 44, energization of the circuit of a motor 24 or 124, according as contacts 45 or 46 are closed ; this motor remains energized for the remainder of the period of the contact made by the brush 32 and the contact member is thereby displaced to an extent and in a direction depending upon the difference referred to above. When the relay 25 or 26 is deenergized the members 1 and 2 are brought into contact by the re-energization of the magnet 5 and the motor 13 is then driven with a corresponding direction and speed to effect the required adjustment of the prime mover speed. The frequency indicator 1 may receive the adjusting movement instead of the counter member 2.

Class- 146(2) A case for sections of maps which may he selectively chosen so they may be read through openings or windows, comprises a shell 10 with its opening 13 and a drawer 14 with a transparent base forming a window for also viewing a map section, means being provided for attaching one or more preselected map sections to the shell and for retaining the remainder to the drawer when it is partly withdrawn. As shown the sections 20 are formed with turned up portions 21, the lower edge of which is held by a finger 25 of a slide 22 adjustably mounted on a rod 23 and set by a selector knob 29. At the same time as this slider is set a second slider 31, attached to the drawer 14 is also moved by means of the finger 25 engaging iri a recess 38 in the slider 31. This slider has a finger 36 which overlaps the upper edge of the card next to that held by the finger 25 so that one group of sections remain in the drawer 14 and the remainder are drawn nearly out by the shell. A detent spring and socket ensures accurate location of the slides which are locked in position, during the time the draw is open, by a pin e.g. pin 47 engaging in notches 48 in the slides. In a modification, (Fig. 8, not shown), the map sections have flat tabs which are gripped by spring urged levers pivotally mounted on adjustably set slides. The locking means may comprise a pin on the end of a spring lever which engages in perforations in the map sections.

IPC: C11D13/04
Filed: 1962-09-04
Abstract: <PICT:0969112/C4-C5/1> <PICT:0969112/C4-C5/2> In a continuous process for making soap in which the saponified mass of soap is grained out with spent lye withdrawn from the process, the alkalinity of the soap mass is neutralized, preferably to below 0.2% free NaOH, by mixing thoroughly with a fatty acid or an easily saponifiable fat, e.g. coconut, palm or castor oil, before separating the grained out neat soap from the spent lye.  As shown in Fig. 1, saponified soap mass passes by line 1 to tank 2, which is also supplied with fatty acid or fat by line 4, with spent lye by line 6, and optionally with brine by line 7 if the lye concentration becomes too low, the system tank 2 and line 3 being maintained at 90-95% C. Grained out neutralized soap passed by line 8 to centrifuge 9, whence spent lye passes by 10 to glycerol recovery.  Separated soap enters tank 12 which is also supplied by 15 with brine and by 16 with nigre from a later fitting stage.  The mass then passes to centrifuge 18, spent lye returning by line 6, while the soap passes by 19 to line 21 and tank 20, which latter is also supplied with a 5-6% solution of a mixture of NaOH and NaCl by line 23.  The fitted mass passes by 24 to centrifuge 25, the nigre being returned by line 16 while the separated soap leaves by pipe 26.  Fig. 2 shows a modification in which tank 2, line 3, and centrifuge 9 of Fig. 1 are replaced by a single countercurrent centrifugal extractor 27.  Soap mass enters the light phase inlet 1 and spent lye enters the heavy phase inlet 6, fatty acid or fat being admitted to the light phase inlet at 4. Neutralized lye leaves at 10 to glycerol recovery and the grained out neat soap is discharged by pipe 11 and passes to a subsequent graining out stage as in Fig. 1. Specifications 549,386, 697,244, 794,428 and 941,937 are referred to.

Abstract: 748,675. Manufacture of electric fuzeheads. IMPERIAL CHEMICAL INDUSTRIES. Ltd. Oct. 11, 1954 [Dec. 9, 1953], No. 34259/53. Class 9(1) Electric fuzeheads comprising sheet metal pole pieces separated by insulating material and connected by abridge wire embedded in bead of deflagrating composition are manufactured from a metal strip 10, Fig. 1, with evenly-spaced acute-angled notches 11 along the edges and regularly spaced slots 12 parallel to the length of the strip. The strip is bent along its longitudinal axis, which is coincident with one edge of the slots, until the two sides of the fold make an angle of 45 degrees. A wire 14 is then wound around the strip, being carried transversely across the middle of the slots to engage opposing notches 11 and pass diagonally at the back of the strip to the next pair of notches. Thin metal strips 15 are then laid parallel to each other on the strip 10 with their nearer edges coincident with the edges of the slots and spot welds 16 are made above the resistance wires 14 to secure the strips 15 and wires 14. A pressboard sheet 17 is then inserted in the folded strip 10, which is further bent and secured by cement to the pressboard. Surplus material between the bridge wires is cut away to give a comb-structure, as on right-hand of Fig. 4. The bridge wires are then coated by dipping in a dope comprising a deflagrating composition and may be given a waterproof coating. The lead wires may then be attached e.g. by soldering. In an alternative embodiment, the resistance wire 24 is wound on to the slotted strip 20, while the strip is flat. Bared ends of insulated lead wires 25 are spot-welded to the strip above the resistance so fastening the wire across the slots. Two strips 27, 28 of insulating material are cemented to the underside of the metal strip 20, which is then bent to the form of Fig. 8. The bridge wires are coated as before. Fig. 9 shows a, machine for carrying out the manufacture. A strip 30 of tinned sheet passes through a punch 29 which stamps out the slots 31 and makes the notches 32. The punched strip passes to dies 33 which bend the strip to a 45 degrees angle and feed rollers 34 pass the bent strip through rotating mechanism 36, which winds the wire from a reel 35 around the strip. Narrow steel ribbons from bobbins 37 are fed to the strip 30 by rollers 38 and spot-welded by electrodes 39. Surplus wire beneath the strip is then removed and a pressboard strip 40 coated with adhesive is sandwiched in the metal strip 30. The assembly then passes into clamping. jaws 41 in a rotatable star-shaped holder 42, where it is heated to set the adhesive. The holder is then rotated through 90 degrees, the length within the jaws 41 being cut off by a knife 43 and carried into a punching device 44 which removes surplus material to form the comb 45. Rotation through a further 90 degrees carries the comb to the release position. The combs are then dipped to form the beads on the bridge wires and afterwards cut to give the fuzeheads.
