Title: Method for the electroless deposition of nickel/iron layers on a substrate which is not an electrical conductor
IPC: C23C18/50
Filed: 1968-11-29
Abstract: 1,248,220. Magnetic structures. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 29 Nov., 1968 [1 Dec., 1967], No. 56837/68. Heading H1H. [Also in Division C7] In a process of electrolessly depositing Ni-Fe alloys on a non-conducting substrate such as glass or a plastics material, the substrate is first chemically treated, sensitized in a tin chloride solution containing e.g. sodium lauryl sulphate, then baked e.g. at 80‹ C., activated in a nobile metal salt solution such as PdCl 2  and finally coated in a bath containing Ni and Fe. In the case of a plastics substrate the chemical pretreatment is effected with chromosulphuric acid or in the case of glass with an acid polish containing alkali salts of HF, H 2 SO 4  and buffers. The coating bath contains 2À5-4 g/l. of Ni ions, 0À8-2 g/l of Fe ions, 2-8 g/l. sodium hypophosphite, 40-80 ml/l. of hydrazine and 22 g/l. potassium sodium tartrate. The pH is maintained at 10.5 by the addition of concentrated ammonia. Deposition may be carried out in the presence of a magnetic field and the coating preferably consists of 81% Ni and 19% Fe.

Title: System for determining the fatigue of a structure experiencing varying stresses
IPC: G01M99/00
Filed: 1971-12-09
Abstract: 1374107 Measuring structural fatigue electrically; measuring peak-to-peak voltage SOC NATIONALE INDUSTRIELLE AEROSPATIALE 9 Dec 1971 [23 Dec 1970] 57239/71 Headings G1N and G1U The accumulated fatigue damage from vibrations to which a member is subjected is determined by the extent of stress developed in the member, the number of cycles of alternating stress and constants based on the material. The stress in a member P Fig. 1, e.g. a helicopter blade, is measured by a strain gauge bridge 1 and fed to a channel V 1 , to develop at 5 a signal based on the peak-to-peak value of each stress cycle, and to a channel V2, to determine the number of stress cycles. These signals are multiplied at 12 and fed to an integrator 14 which shows the accumulated fatigue. To determine the peak-to-peak voltages developed in the strain gauge bridge 1, the alternating signals are fed through reverse diodes D 1 , D 2  Fig. 2 to charge capacitors C 1 , C 2  to the negative and positive peaks respectively, the peakto-peak value being the output of amplifier AD 1 . The alternating signals are also fed through a pulse transformer TP 1 , the negative half-cycles suppressed by diode D 3  and the remaining pulses I, &c., each triggers a monostable network at the start of a fresh positive half-cycle, whereby transistors TF 1 , TF 2  are made conductive and capacitors C 1 , C 2  are discharged. When the network restores, capacitors C 1 , C 2  are charged to the peak values of each half-cycle of the next alternation. The peak-to-peak stress values developed at 5 are compared at 8 with a predetermined reference value v. If the measured values are not greater than v they do not contribute to fatigue damage, and a gate 13 is kept closed to prevent the product output from 12 reaching integrator 14. The gate 13 is also controlled by circuit 15 in channel V3 to be available to the product signal at 12 at the instant of the positive maximum of the stress signals.

In a machine having a member urged against material passing between it and a base-plate, the member is of magnetizable material and is attracted by a magnetic holding device arranged in the base-plate, the magnetic holding device comprising spaced permanent magnet poles and pole zones of magnetizable material overlying the poles, the zones and poles being relatively displaceable to vary the magnetic force. The member may comprise a roller or squeegee. As shown, Fig. 1, the holding device comprises a casing 1, the cover 5 of which contains a row of circular discs 6 of magnetizable material. Permanent magnets 2 separated by polepieces 3 are mounted within the casing and are clamped together by means of a rod 4.

Title: Electrically conductive zine oxide
IPC: H01B1/08
Filed: 1966-12-30
Abstract: Zinc oxide is made electrically conductive by treating it with a halogen compound of a Group IV element at 400 DEG  C. to 900 DEG  C. in a non-oxidizing atmosphere.  The compounds have the formula XMY3, where M is the Group IV element, X is halogen, hydrogen or an alkyl group of 1 to 3 carbon atoms, and Y is halogen, and may be used in amounts less than 10% by weight of the zinc oxide.  If the halogen compound is a solid at room temperature, as with titanium tetrafluoride and the germanium iodides, it may be mixed with the zinc oxide before heating.  With the germanium iodides, the atmosphere may be neutral or reducing; otherwise a reducing atmosphere may be used, such as hydrogen or carbon monoxide.  Two methods are given: either the halogen compound and a carrier gas such as dry air, hydrogen, carbon monoxide or nitrogen are passed through zinc oxide particles at ordinary temperatures until no more halogen compound is absorbed, when the reducing gas alone is passed through at high temperature; or the halogen compound is passed through vaporized, at the high temperature, mixed with the reducing gas, and no separate carrier gas is needed.  The rates of flow may be such as to fluidize the zinc oxide particles.  Specified elements M are silicon, carbon, titanium and germanium, and examples use titanium tetrachloride, silicon tetrachloride, germanium tetrachloride, germanium tetrabromide, germanium tetraiodide, germanium tetrafluoride, methyltrichlosilane, trichlorosilane, chloroform, carbon tetrachloride and trichloroethylene as the halogen compound, and a mixture of these may be used to vary the colour of the product.
