Title: An improved process for protecting surfaces against chemical plating
Inventor: KLEJN HEINZ-GUENTER
IPC: C23C18/16
Filed: 1965-01-13
Abstract: Metallic surfaces are protected against chemical plating, particularly an 18/8 Cr-Ni steel vessel containing a chemical nickel plating bath for coating iron plates immersed therein with Ni-B or Ni-P, by connecting the surfaces into an electric circuit containing a plating bath electrolyte, at least one counter-electrode and D. C. voltage source, applying to the surfaces an electric potential corresponding on the current density/potential curve to the rest potential or to the protection potential region lying between the mottling potential and the transpassivity, and adjusting the current density to not more than 104A/cm2.  Preferably, with the surfaces to be protected connected as the anode and the counter-electrode as the cathode, the potential is regulated potentiostatically by at least one standard electrode immersed in the plating bath.  In a nickel plating bath, standard and counter-electrodes can be used made of nickel or a Ni-B or Ni-P alloy corresponding to composition of the alloy chemically deposited from the bath; the electrode may be made from a molten Ni alloy or one applied by chemical plating on other material such as Cu, brass, Fe, SiC, graphite, glass, resin or porcelain.  The plating bath may contain sodium borohydride or hypophosphite, or a borazane or borazole: e.g. (a) 30 g/l NiCl2, 10 g/l Na citrate and 10 g/l NiCl2, 40 g/l NaOH, 60 g/l ethylene diamine, 30 g/l NaF and 0.6 g/l Na borohydride.  For plating other metals such as Co, Fe or Cu, or a B- or P- containing alloy of one of these metals, a standard electrode made of the corresponding metal or alloy is used.

Abstract: 347,112. Selectors responsive to code signals. LIPMANN, C., 5, Rue des Chalets, Besancon, France, STRAHM, A., Moltkestrasse, Schramberg, Germany, and QUINCHE, A., 32, Quai Vauban, Besancon, France. Jan. 20, 1930, No. 2012. Convention date, Jan. 26, 1929. [Class 40 (iv).] In a selector responsive to code signals in which a code wheel checks the incoming signal, a signal received during a break period energizes a relay which restores the apparatus to normal. The invention is described as applied to a selector of the type described in Specification 304,726, [Class 40 (iv), Telephones &c.]. In the embodiment shown in Fig. 3 the two code wheels 10, 54 are mounted on the same shaft, the indentations on 54 corresponding with and being slightly longer than the projections on 10 and vice versa. When an incoming signal is received 36 energizes and 20 pulls up, allowing 5 and 7 to engage, and the code wheels start revolving. During the normal signal periods 22 passes over indentations 10 whilst during the normal break periods 22 engages 10, shorting contact 34 to hold 20 energized. During these space periods 56 engages 54 and should a signal then be received and 36 respond, contacts 43 make, energizing 57 to break the circuit of 20 and restore the selector. In the embodiment shown in Fig. 1, when a signal is received both 20 and 40 energize, code wheel 10 revolves and wheel 42, engaging with wheel 7, moves. When the signal portion ceases 40 releases but 20 is held over 22 and 10 until the next signal is due to commence. Should the signal be prolonged however 40 remains energized and pin 44 opens contacts 45 to release 40 and 20 and restore the apparatus to normal. The magnet 40 may be released by a delayed armature 47 on the impulse relay 36, Fig. 2. The movement of 47 is retarded by the wind vane 51, and if the signal persists longer than the operating time of 47, springs 52 are opened, releasing 20 to restore the apparatus to normal.

Title: Compensating interference from solid state image sensing devices
IPC: H04N5/217
Filed: 1976-01-08
Abstract: 1526801 Television BRITISH BROADCASTING CORP 8 Jan 1976 [17 Jan 1975] 2194/75 Heading H4F A method of compensating for undesired signal components in the output of a solid state image sensing device 10, comprises shielding said device from all incident light and storing in a store 20 the output signal obtained by scanning the device to provide a first stored signal, subjecting device 10 to a maximum illumination from a lamp 44, subtracting the first stored signal from the output signal obtained by scanning the device, and storing in a store 30 a second stored signal dependent upon the resultant of the subtraction, the output signal from the device, in normal use, having the first stored signal subtracted therefrom and being modified by the signal from store 30 to produce a signal representative of the resultant of the subtraction divided by the value represented by the second stored signal. The method therefore reduces the effects of a first signal component caused by variations in dark current or breakthrough from clock pulses and which is present in the output of the device 10, and of a second signal component caused by sensitivity variations or by varying transfer efficiencies and which is a linear function of signal level. The signal from device 10, which consists of an array of photosensitive cells, is passed through an analogue-to-digital converter 16 to a subtractor 24, which also receives the signal from store 20. The subtractor 24 is coupled to a logarithmic converter 28 and to a subtractor 34, which also receives the signal from store 30. An antilogarithmic converter 36 is connected to the output of subtractor 34 and has its own output connected to a digital-to-analogue converter 38. A dividing circuit may be used in place of subtractor 34 and converters 28, 36. The stores may apply the average of several scans to subtractors 24, 34 to reduce the effect of random noise in the output of device 10. A sequencer 42 connected to scanning circuits 12 of device 10, to lamp 44, and to switches 22, 32 for stores 20, 30 respectively may control the procedure for storing the desired signals.
