Title: Improvements in or relating to the production of cutting edges
Inventor: GALE ROBERT JAMES
IPC: C25D1/00
Filed: 1965-01-28
Abstract: 1,135,023. Electrolytic production of cutting edges. WILKINSON SWORD Ltd. Jan.25, 1966 [Jan.28, 1965], No.3736/65. Heading C7B. In a method of electro-forming or electrofinishing the cutting edge of a razor blade to form a cutting edge of desired surface contour, the flow of current is limited differentially by screening positioned adjacent said edge. Said method may be carried out in a longitudinal cell through which razor blade strip may be continuously passed, said cell comprising a housing 10 which forms the cathode and is maintained at earth potential, screening means 12, and anodes 14. The adjacent faces of the screening means 12 are positioned a sufficient distance apart to allow the razor blade strip to pass therebetween, and the parts of said screening means adjacent the edge of the strip 13 to be sharpened are shaped such that the amount of metal removed from the strip during electrolysis is progressively less as the distance from the tip thereof increases, e.g. the surface of the screening means adjacent the blade edge may lie at an angle of 20-40‹ C. to the plane of the blade strip, as shown. The cell is provided at one end with inlet ports (17) Figs. 1, 2 (not shown) via which electrolyte is fed to each anode chamber 12a and each cathode chamber 12b, and with outlet ports (18) at the opposite end of the cell for removal thereof. The final portion of the cell beyond the ports (17), (18) respectively is closed by a manifold of insulating material such as ceramic or plastics material, e.g. P.T.F.E., to which manifolds air is fed under pressure to prevent or reduce escape of electrolyte from the cell. The screening means may be of a ceramic or plastics material or of a metal which is at least partially polarized in the operational condition of the cell, e.g. titanium, tungsten, tantalum, niobium or zirconium. The angle formed between the blade strip and that part of the screening means inclined thereto may decrease as the blade progresses through the cell.

Abstract: 556,246. Automatic control systems for electric motors. JUHLIN, G. A., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. March 23, 1942, No. 3847. [Class 38 (iv)] [Also in Group XXXVII] Speed.-The generator WG of a Ward-Leonard system, particularly for an electrical winder installation is controlled by a sensitive and rapidly responding auxiliary generator such as a metadyne or D.C. machine of armature reaction excited type EA so that if the speed of the motor M is not in conformity with the setting of a speed control member WER, differentially related components of the excitation of 'the auxiliary generator will rectify the error. One excitation winding EF2 may be subjected to a voltage representing the setting of the speed control member which may accordingly be coupled to a potentiometer element EGT and an opposed excitation winding EF1 subjected to a voltage representative of motor speed namely to the tachometer generator TGA. Alternatively a single excitation winding on the auxiliary generator may be subject to opposed voltages representative of the setting of the speed control member and of the motor speed. Fig. 2 (not shown) illustrates a complete system in which the metadyne has a further field winding excited in accordance with the difference between a predetermined voltage from a potentiometer and the voltage across a resistance in the armature circuit of the motor whereby a predetermined overload limitation is obtained under both normal and regenerative operation thereof.

IPC: B65G49/04
Filed: 1960-02-03
Abstract: 882,035. Electroplating. CORODE ELECTROCHIMIE S.p.r.l. Feb. 3, 1960, No. 3899/60. Class 41. [Also in Group XXX] An apparatus for treating articles, e.g. for electroplating, in a series of liquid baths comprises a large container 14, which may be the plating tank, and a plurality of small containers 6 located above the tank 14, means being provided for moving the articles through the tank 14 and for immersing them in turn in the containers 6, and means for transferring articles from the tank 14 to the containers 6 and vice versa. The apparatus comprises twenty containers 6 arranged in a circle in two groups of ten with a loading and unloading bay at one side and a lifting station at the other side located between the groups. A central rotatable spindle 3 carries a platform 5 for the containers 6, and a compressed air cylinder 10 raises and lowers a rotatable disc 7 provided with hooks 8. A similar rotatable disc 12, which is not vertically movable, is mounted above the tank 14. The discs 7, 12 are alternately, intermittently rotated by notched discs 11, 13 respectively, which are controlled by an intermittently operated electric motor 21 which at each operation rotates each of two crank discs 22 through 180 degrees, alternately to rotate the discs 11, 13 through 15 degrees, which is the angular distance between adjacent containers 6. The discs 22 are 180 degrees out of phase, so they rotate each disc 11, 13 alternately. The sequence of events is as follows: The motor 21 rotates the discs 13, 12 through 15 degrees to bring a rack 23 in the tank 14 to the lifting mechanism 17 ... 19. A compressed air cylinder 19 raises hooks 17 which engage a bridge 16 on the rack 23 to lift the rack to the dotted position in Fig. 1, a channel 20 guiding a hook support member 18 to carry the parts 17, 23 past the hooks 8 on the disc 7. The cylinder 10 next raises the disc 7, hooks 8 thereon engaging the bridge 16, and the motor 21, through disc 11, rotates the disc 7 to take the rack 23 above the first of a group of ten containers 6, and to bring another rack 23 from the last of the other group of containers 6 to the lifting mechanism. The disc 7 is then lowered, immersing appropriate racks 23 in the containers 6, and leaving the other rack 23 supported on the hooks 17 at the lifting station. The members 17, 18 are next lowered to immerse this rack in the tank 14 and transfer the rack to the disc 12, and finally the disc 12 is rotated 15 degrees to bring a fresh rack to the lifting mechanism. Thus each rack 23 goes through one group of containers 6, then through the tank 14, and finally through the rest of the containers 6. The discs 7, 12 may be replaced by arms.

Title: Improvements in or relating to ultrasonic flaw detecting apparatus
IPC: G01N29/06
Filed: 1956-02-10
Abstract: 815,071. Ultrasonic flaw detection. GLASS DEVELOPMENTS Ltd., and SPROULE, D. O. Feb. 8, 1957 [Feb. 10, 1956], No. 4276/56. Class 118 (2). In an ultrasonic flaw detector the specimen (see Fig. 1) is supported in a tank filled with suitable liquid (e.g. water) sufficient to cover it and a movable trolley 12 (see also Figs. 2 to 5 (not shown)) carries the transmitter-receiver probe head 22 which is movable across it; the angle of the probe relative to the surface of the specimen is maintained constant (see Figs. 7 and 8 (not shown)). The probe 22 (sec Fig. 9) reciprocates successively in adjacent narrow strips along the specimen and the received pulse echoes are fed via gate circuits to amplitude discriminators whose outputs are recorded by styli PS1 ... PS4 on a reciprocating web of electro-sensitive paper; cathode-ray displays of the received echoes are also given. 2 Mc/s. trigger pulses at a repetition frequency of 50 c/s. are fed to a transducer T (see Fig. 9) and to a transmitting coil TC associated with a delay line DL on which are provided receiver coils RC1 ... RC4, so dimensioned that each one products a square output pulse of a duration equivalent to the range of possible echo times from a region of predetermined thickness, and so located that successive thickness regions of the specimen are examined. The output of coil RC1 (for example) opens gate G1 (see also Fig. 10 (not shown), for the period corresponding to the first quarter of an inch thickness of the specimen and permits linearly amplified receiver signals to pass to amplitude discriminator AD1 (see also Fig. 10 (not shown)) which has four discrimination levels each having an associated memory circuit such as a capacitor charged through a rectifier so that in accordance with the amplitude of the received echo some or all of the fixed brushes B1 are given a sustained potential. The distributer switch DS carries metallic contacts CT2 connected to the recording styli; contact sets CT1 or CT3 are earthed via arm A, depending on the direction of traverse. The reciprocation of the distributer switch and of the recording paper follows that of the probe by the use of servomotors SA; the perpendicular stepping of the styli follows that of the probe by means of servomotors SB. The form of record obtained is illustrated by Fig. 11 (not shown). Cathode-ray tube AS provides a range-amplitude form of display and tube BS, a rectangular plan-position display with the horizontal dimension representing the length of the specimen and the occurrence of bright spots in the vertical direction indicating the positions of discovered flaws. The number of gate circuits G, and the number of amplitude discriminator levels, may be changed. The probe head may comprise a combined transmitter/receiver transducer; and several probes and their associated apparatus may be used to provide the simultaneous inspection of several regions.
