Title: Improvements in or relating to addressing or similar printing machines
IPC: B41L45/00
Filed: 1928-03-12
Abstract: 290,191. Spiegel, May, Stern, Co., (Assignees of Gollnick. P. A., Toolan, J. J., and Harred, G.). May 9, 1927, [Convention date]. Addressing and like machines ; stencilling- apparatus; inking-apparatus.-In an addressing or similar printing-machine of the kind employing stencils 4, Fig. 3, which are advanced in procession along guides 3 to printing position above a reciprocating platen 7 on which an envelope &c. to be addressed is placed, printing is effected by a rotating ink-pad 10 carried by arms 8 fixed on a rotary shaft 13 mounted in a carriage 9 adapted to rock about a pivot 21. The pad 10 is inked by contact with a roller 42, which is supplied from a duct-roller 46 through distributing and messenger-rollers 43 - - 45. The roller 46, which is supported in pivoted arms 85, and is pressed against the roller 45 by springs 87, is geared to the roller 45, which is rotated step-by-step by a ratchet 75 on the roller and a pawl 76 oscillated by an arm 77 having an adjustable pin-and-slot connection with a bell crank 78 rocking about a pivot 79 under the influence of a cam 81 on a driving-shaft 25. The rollers 42, 44 are made of rubber and are driven by gearing from the rollers 43, which is geared up to the shaft 25. The roller 42 is resiliently mounted in arms 49 pivoted on the carriage 9, and the roller 44 is carried by arms 58 pivoted to arms 59, Fig. 5, which are periodically rocked about a pivot 63 by a cam 66 on the shaft 25. The arms 58 and 59 are under the influence of springs 62, 67 respectively, and the movement of the arms 59 causes the roller 44 to wipe ink off the roller 45 and transfer it to the roller 43. The shaft 13 carrying the pad 10 is fixed to a gear 14 rotated by gearing from the shaft 25. The gear 14 and a gear in mesh therewith have the teeth cut away to allow the pad 10 to remain stationary while the impression is made. A cam on the gear 14 is engaged by a pin on the other gear to bring the teeth into mesh again. The carriage 9 is rocked by a cam 39, Fig. 3, acting through a bell crank 36 connected by a link 35 to a rod 34 bolted to a cross-bar 31 on the carriage. A driving-motor is stopped by moving over to the right a hand-lever 68, Fig. 5, connected by a rod 90 to a switch. At the same time, a cam 70 on the lever by engaging a pin 71 on one of the arms 58 raises these to disengage the roller 44 from the rollers 43, 45, and lugs 72 on the arms 59 engage the arms 49 and disengage the roller 42 from the roller 43.

Title: Improvements in or relating to method of and apparatus for supersonic inspection
IPC: G01N29/04
Filed: 1947-03-20
Abstract: 636,340. Supersonic inspection devices. SPERRY PRODUCTS, Inc. March 20, 1947, No. 7674. Convention date, March 28, 1946. [Class 118 (ii)] Supersonic testing apparatus, for measuring and for detecting flaws in an object, comprises an oscillator energizing a piezo-electric element in contact with an object to produce continuous waves, means for impressing an identifying' signal on the oscillations of the element, and means for receiving the oscillations and identifying signal issuing from the object and converting them into electric oscillations. As shown, a crystal 12 in contact with an object 10 to be tested is operated continuously at a predetermined frequency by an oscillator 15. The crystal also receives reflections from the opposite face 14 of the object or any flaw D therein. The crystal oscillations are amplified at 20 and impressed across the vertical plates 21 of a cathode-ray tube 22, to cause vertical deviations of a horizontal sweep impressed across horizontal plates 23 by a conventional sweep circuit 25. This sweep circuit 25 is connected by a conductor 40 to a multivibrator 42 so that each time the valve 26 discharges to initiate the sweep, a signal is delivered to the input grid 41 of the multivibrator. The output of the multivibrator is impressed through a conductor 43 on the input grid 44 of an oscillator valve 45 in the oscillator 15. Each generation of a sweep will therefore cause the multivibrator 42 to impress an input signal in the oscillator 15 to give a distinguishing signal 50 as shown on the cathode-ray tube 22, the width of signal being dependent upon capacities 46, 47 and resistances 48, 49. Refections 501 and 50<SP>11</SP> from a flaw D and the face 14 of the object 10, respectively, can thus be identified. If desired, a second crystal may be placed in contact with the face 14 to detect transmitted reflections.

Title: Television receiver
IPC: H01J29/74
Filed: 1937-03-16
Abstract: 492,276. Television; cathode -ray tubes. RADIOAKT.-GES. D. S. LOEWE. March 16, 1937, No. 7679. Convention date, March 21, 1936. [Classes 39 (i), 40 (iii), and 40 (v)] The anode 3 and deflecting plates 6 of a cathode-ray tube are at a high positive potential 1, which is also used for the associated relaxation oscillator 9, 10, 11, and are connected together through a leakage resistance 8, the cathode of 2 the tube and the relaxation oscillator are earthed, and a high voltage condenser 7 couples the deflecting plate to the oscillator. When the coupling transmits all the frequencies equally well, the available output from the oscillator is made large compared with the consumption of the leakage resistance by making the resistance 10 smaller than the resistance 8. Otherwise the coupling is designed to transmit the lower frequencies better than the higher by tapping the output from the series resistance 10, Fig. 2 (not shown), or by using a low-pass resistance-capacity filter, Fig. 3 (not shown). Alternatively, the deflecting plates are screened from the cathode ray by reticulated grids, which are connected to the anode 3, and the deflecting plates are biassed negatively relatively to the anode to prevent electronic current reaching the plates, Fig. 4 (not shown). It is then possible to deflect the ray without absorption of power, and the leakage resistance can be of such size that the relaxation oscillator is not appreciably loaded by the capacity of the circuit of the plates.

Title: Improvements in and connected with the manufacture of chromates
IPC: C01G37/14
Filed: 1922-03-17
Abstract: 177,174. Jouve, A. J. B., Helbronner, A., and Soc. Hydro-Electrique et MÚtallurgique du Palais. March 17, 1921, [Convention date]. Alkali chromates and bichromates and iron oxide and carbonate, obtaining.-Alkali chromates are obtained by electrolysis of alkali carbonate solution with anodes of a chromium alloy such as ferrochrome, and without a diaphragm. Iron is precipitated as oxide or carbonate which is removed. According to the Specification as open to inspection under Sect. 91, (3) (a), the chromate may be converted into bichromate by continued electrolysis after complete conversion of the carbonate. Concentrated solutions are preferably employed, so that the, resulting chromate or bichromate solution is 'near the crystallizing point. To obtain neutral chromate, bichromate may be first formed and excess.of alkali carbonate then added. Iron oxide is removed from time to time by agitation and filtration of the liquid or by centrifugal separation. The anodes may alternatively consist of carbon chromite and tar heated below fusion to partially reduce the oxide of chromium. The cathodes may be of lead. Ferrochrome anodes should contain not less than 40 to 45 per cent of chromium. A high current density of some hundreds of amperes per square metre is employed so as to heat the electrolyte. Alternating current may be used. The electrolysis may be carried out in a series of baths between which the electrolyte circulates. This subject-matter does not appear in the Specification as accepted.

Abstract: 958, 083. Calculating machines: division. WALTHER-BUROMASCHINEN G.m.b.H. Feb. 28, 1962 [April 19,1961], No. 7895/62. Heading G4B. When overflow is detected in the quotient register, automatic division is stopped, the divisor, remainder and quotient are cleared and an overflow signal is given. Although the signal may be audible or visible, preferably the divisor and remainder are printed each together with an overflow symbol. Movement of rack 1 (Fig. 2) drives wheel 11 through wheels 7, 8. Lever 12, reciprocated by wheel 11, is commonly pivoted to an arm 14 and pawl 13 a tooth 17 of which steps a wheel 19 one tooth for each revolution of shaft 6. Wheel 19 rotates shaft 20 (Fig. 3) and with it wheel 21 which by axial movement of shaft 20 is brought into engagement with successive pinions 30. Movement of pinions 30 is transmitted by transfer wheels 32 to quotient register wheels 66. A collar on wheel 32 associated with the highest order number wheel of the quotient carries a tooth 32, which if the wheel 32 is caused to make more than one revolution momentarily lifts a slider 36. This rocks a yoke 39 anticlockwise and causes a bar 47 carried by an extension 40 of the yoke to push a slide 49 rearwardly so that it latches with a shoulder 53. The rearward motion of slide 49 releases a print hammer 59 carrying the overflow symbol (Fig. 2). A second pin 41 on extension 40 deflects a lever 42 to cause a rod 45 to lower and thus initiate in some manner not described, the operations necessary to stop division. The quotient is cleared by bringing the wheels 66 into engagement with the racks 1. The tilting of cradle 65 to do this causes pin 47 to bear on inclined surface 68 unlatching slide 49 from shoulder 53.
