Title: Chemical plating process
Inventor: LEVY JOSEPH PEPPO
IPC: C23C18/36
Filed: 1962-04-19
Abstract: A process for chemically plating a metallic or non-metallic surface with metal (e.g. Ni or Co from a hypophosphite bath) includes the steps of treating the surface to be plated with a solution of palladium chloride in a solvent comprising acetone with or without one or more additives, drying the surface and immersing it in a chemical plating bath.  The additives may be H2O, CH3CHO and those esters of methyl, ethyl, butyl and propyl alcohols which are readily volatile at temperatures up to 200  DEG C., e.g. butyl formate, methyl salicylate, ethyl salicylate, ethyl benzoate, ethyl succinate, ethyl acetate, iso-propyl acetate and ethyl propionate.  In dissolving the palladium chloride in the acetone, HCl may be employed which may subsequently be neutralized with NaHCO3.  The surface of the article, before treatment with the solution, may be heated to a temperature up to 200  DEG C. and, after treatment, the drying may be at a slightly higher temperature.  The treatment with the palladium chloride solution and any heating steps may be repeated. In the examples, the Ni or Co plating baths used are: a Ni bath maintained at 65-75  DEG C. of .Na4P2O7.50 gs./l .Ni sulphate.25 gs./l .NaH2PO2.25 gs./l .Na4OH.sufficient to maintain the ..pH at between 10 and 11 or a Co bath maintained at 95  DEG C. of .NaH2PO2.30 gs./l .Na citrate.20 gs./l .Co chloride.35 gs./l .NH4Cl.50 gs./l .NH4OH.sufficient to maintain ..the pH at 9 The articles a, the solvents s for the palladium chloride, the temperature t1 of the heating pretreatment and of the post-treatment t2 are as follows:  1) (a) nylon, melamine, epoxy resins, alkyd resins, polyester resins, polyformaldehydes and pyrophyllite; (s) acetone; (t1) 120-150 DEG C.; (t2) 200  DEG C.

Title: Improvements in the design and manufacture of pre-stressed concrete structures subjected to bending moments in two opposite directions and to shear especially railway sleepers or the like
IPC: E01B3/34
Filed: 1943-09-22
Abstract: 565,829. Pre-stressed concrete. PRESTRESSED CONCRETE CO., Ltd., and MAUTNER, K. W. Sept. 22, 1943, No. 15516. [Class 20 (iv)] Concrete structures, particularly railway sleepers, are provided with prestressed reinforcements which extend over the full length and are so arranged that, notwithstanding reversed bending moments at different sections, the tensile stress in the concrete is kept below its tensile strength. This is done by (1) forming the concrete with a different cross-section at places of bending moment having opposite sign, e.g. by a rebate in the middle portion of a sleeper, or by varying the width and side slope of the section, so that the relative positions of the centres of gravity of the concrete and reinforcement cross-sections are reversed ; (2) as in (1), but reducing instead of reversing the separation of the centres of gravity ; (3) as in (1), but keeping the separation of the centres of gravity constant, in conjunction with an increase of the pre-compression effect for sections remote from the ends sufficient to keep the tensile stresses within the required limit ; (4) by reversing the relative positions of the centres of gravity, or by reducing their separation while not reversing them, by removing the adhesive bond of some of the stretched reinforcement on a length which has the greater bending moment. Fig. 5 shows a half elevation of a railway sleeper with three layers r<1>, r<2>, r<3> of stretched reinforcements. Fig. 5A shows 'a cross-section at AA, and Fig. 5B a cross-section at BB. The centre of gravity of the reinforcement is at S and of the concrete at the two sections at G respectively. In Fig. 5A, the precompression produces a higher compressive stress at the bottom than at the top: In Fig. 5B, the compressive stress at the top may be made equal to, or greater than that at the bottom by reducing the distance e<1> between S and G to zero, or reversing it as at e<2>. When the point G still remains above S, but at a less distance than in the section AA, the compressive stress at the top is increased, but is smaller than at the bottom. If the adhesive bond between reinforcement and concrete is removed along a length m of the layer r<3>, the distance e, Fig. 5A, is increased, but not e<1> in Fig. 5B. Specifications 338,864, 338,934, [both in Class 20 (iv)], 364,621, 393,576, 393,606, [all in Group V], 541,835, 554,693, 554,970 and 560,521, [Group XXX], are referred to.

IPC: H04B3/14
Filed: 1951-06-29
Abstract: 730,558. Impedance networks. POSTMASTER GENERAL. Oct. 22, 1952 [June 29, 1961], No. 15536/51. Class 40 (8). An electrical transmission network has an output control circuit which includes means for varying the amplitude and polarity of the output from the network or from each of one or more tapping points. For example the output from the network may be applied to two terminals 1 and 0. Terminal 1 is connected to a differential capacitor Cd which is also connected to terminals 2 and 3 of a differential amplifier 4, and terminal 0 is connected to the remaining terminal of the amplifier. The amplitude and polarity of the output is varied by adjusting capacitor Cd. Shunt capacitors C1 and C2 are provided to compensate for any inequality of amplification. If grid leaks, represented by potentiometer R1 are required at the input to amplifier 4, resistors Rd and KRd are provided in association with capacitor Cd and they can be adjusted to render the overall response independent of frequency. Several tapping-points along a delay line may be provided with these networks. In order to avoid interference between them when one is adjusted, two coupled capacitors are provided at each tapping-point, one compensating the effect of the other on the line.. The low frequency components of signals may be lost in these networks and may be restored by separate low frequency amplifiers or by the use of complementary networks.

Abstract: 544,921. Alternating current machines. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 25, 1940, No. 15710. Convention date, Oct. 25, 1939. [Class 35] A dynamo-electric machine slotted member, such as an induction motor rotor with a variable start-torun inductance and effective resistance, has some of the conductors formed as single low-resistance bars in a part of the slots and as multiple-resistance, bars in another part of those slots, the multipleresistance parts including an inner low-resistance and an outer high-resistance portion. End rings and intermediate connections between the bars form them into a complete winding. Fig. 1 shows a form in which one packet of laminations has single low inductance conductors 15 in large slots and another packet has multiple-resistance conductors consisting of high-resistance and low-resistance portions 16, 17 connected by a portion 14 in the narrow neck joining the parts of each slot. The slots of both forms are collinear axially and the two sets of conductors are electrically continuous, e.g. by means of a conducting ring placed between the two packets and connected to the adjoining ends of both sets of bars. Alternatively to alternating packets with different slot sections, all the laminae may be made similar with alternating slots and conductors of the two sections shown in Fig. 1 and as shown in Fig. 8, the order of the slot and conductor sections is reversed in successive packets. The two sections of the conductors may be cast together integrally or joined by conducting inter-packet rings. In the form shown in Fig. 4, narrow bars 20 extend through collinear slots in both packets, the slots in one of which are widened at the bottom to receive additional bars 21 on each side to give the required low resistance, and the difference in resistance may be increased by making the conductors 20 of a material of higher resistivity than the bars 21. Fig. 7 shows a core having slots for three types of conductor, viz., large single-section bars 15, multiple section bars, 17, 14, 16 both as in Fig. 1, and bars consisting of large inner sections 25 connected by oblique portions 26 to small outer sections 24, the portions 25 being displaced by one slot from the portions 24 to which they are connected. All three types of slot communicate longitudinally throughout the core length. Interruption of the narrow neck parts 14 may be obtained by reversing the throw of the oblique parts 26 in adjoining packets as described in Specification 544,923.
