Title: Method of phosphating metal surfaces
IPC: C23C22/76
Filed: 1972-09-29
Abstract: 1408604 Blasting VAQ-FOS Ltd 12 Dec 1973 [29 Sept 1972] 45012/72 Heading B3D [Also in Division C7] A method of treating a metal surface to provide a phosphate coating thereon comprises subjecting the surface to a blast of a mixture of abrasive particles and an aqueous acidic solution containing a phosphate, the mean velocity of impact, that is the mean value between the velocity of the slowest and fastest particles in the central area of the blast, with the surface being between 20 and 100 feet per second. The phosphating solution in the blast is atomized by compressed air and air pressure can be varied to vary the impact velocity. If descaling is necessary, the impact velocity is preferably 50 to 80 feet per second. The concentration, temperature and time, which may be as little as one minute, may be varied to control the final weight of the phosphate coating. If the velocity of the impact is too high, the abrasive removes the coating faster than it is formed. The phosphate solution may include accelerators and/or oxidizing agents, such as sodium nitrite. The method is stated as producing a finer crystal structure than that produced by conventional phosphating methods. When treating a succession of metal parts, the mixture may be continuously circulated and, after each circuit, abrasive particles and detritus are separated from the mixture and part of the cleaned solution used to rinse a treated part, the remaining part being remixed with abrasive particles for subsequent use. Partially cleaned and cleaned phosphating liquid may be used to provide two rinses, and a final rinse of water may be used. A thick phosphate coating may be achieved by using a phosphating solution with abrasive following coating using the mixture having abrasive. The abrasive may be alumina having 90/100 grit size, 40 lb. of abrasive being used in 25 gallons of solution which may be zinc phosphate, iron phosphate, manganese phosphate or lead phosphate. The method may be applied to preparing metal billets for extrusion, die blanks for cold hobbing, drawing wire or rod, treating gearwheels, cam-shafts, liners and transmission components to assist lubrication, or to preparing surfaces, such as vehicle bodies, refrigerators, metal sheet and strip for corrosion protection and application of paint or plastic coating.

In a baker's oven, a device for rotating a wheeled transport carriage 17, within an oven chamber 1, consists of an overhead rotary support 11 in the roof of the oven chamber which includes a coupling arrangement by which the carriage is lifted off the floor 19 of the oven as it is moved into engagement with the support. For this purpose, the support 11 comprises a yoke 12 which is carried by a motordriven vertical shaft 9, either rollers 14 being carried by bars 13 on the ends of the yoke to engage U-section rails secured to the carriage and having flared ends, as shown, or U-section rails being secured on the ends of the yoke to engage rollers journalled on the carriage (Fig.6, not shown). In the latter construction only one end of the rails is flared, the other end being closed to form a stop to retain the carriage. In each case the flared ends of the rails act as ramps for the rollers such that the carriage is raised off the floor 19, whereby it may be rotated by motor 15. The carriage may be retained on the yoke by pivoted latches 23, or by the engagement of rollers 14 in openings 26 in the co-operating rail flange. The oven chamber is formed by a perforated plate 4, air being continuously circulated by a fan 7 past heater tubes 8 in the space 3a, over the top of the oven chamber and through the chamber via space 3b and the perforations in the plate 4.

Filed: 1975-10-31
Abstract: 1523779 Soil testing S MARCHETTI 31 Oct 1975 [31 Oct 1974] 45173/75 Heading G1S A soil testing probe comprises, a pressure chamber 2, Fig. 2, supplied with compressed gas through a conduit 18, membranes 7 fixed to either side by clamping rings 8 and gaskets 9, electrically insulated washers 10 supporting the membranes, a cylinder 11 provided with a gas inlet 12 and a gas outlet 13 connected to a conduit 17, a spring 16 acting against a piston 15 slidable in the cylinder, and electrical contacts x, y connected to but separable from the membranes. The cylinder 11 and piston 15 together act as a valve controlling the compressed gas supply and press against the internal surfaces of the membranes after passing through central holes in the washers 10. A control panel at the surface is provided to supply a source of pressurized gas, a manometer or other pressure gauge and electric warning lights. In operation, the probe is pressed into the soil and compressed air is fed into the chamber 2 through conduit 18. This air acts on the membranes 7 and pushes them out into contact with the soil and away from electrical contacts x, y which thus signal the initial movement. The initial pressure is then read. Gas inflow is then continued to further expand the membranes, and this causes the spring 16 to displace the piston 15 and cylinder 11 to left and right respectively and uncover the discharge air port 13. At this point an equilibrium situation is created between the internal and external pressures and another pressure reading is taken. The two readings are then used to calculate a deformability modulus for the soil. An electrical transducer may be used instead of the pneumatic system described.

Title: Threshold logic gate one-way pig means
IPC: H03K19/086
Filed: 1974-10-22
Abstract: 1460215 Transistor logic circuits SIGNETICS CORP 22 Oct 1974 [17 Dec 1973 45651/74 Heading H3T A threshold logic circuit having a plurality of inputs W, X, Y, Z comprises a differential switch 13 for comparing the inputs with a reference to derive complementary output signals A, B which are weighted in accordance with the number of input signals which exceed the threshold ; a level shifter 14 responsive to the signals A, B to produce a plurality of different threshold levels A 0 , B 0 , A 1 , B 1 , A 2 , B 2 , related to the weighted signals; and a threshold detector, 16 or 17, for comparing at least three of the levels A 1 , A 2 , B 0  or B 1 , B 2 , A 0  to produce a logic output indicative of the states of the input signals. As described, the outputs of two threshold detectors 16, 17 are fed to an OR-gate 10c, the output V 0  from which constitutes a 4-bit parity check signal. A second similar circuit is fed with a second set of inputs W<SP>1</SP>, X<SP>1</SP>, Y<SP>1</SP>, Z<SP>1</SP> and the outputs of the two 4-bit parity circuits are combined in an EXCLUSIVE-OR circuit, Fig. 3B (not shown), to provide an 8-bit parity check output. The weighing factor of the threshold steps between outputs A 0 , B 0 -A 1 , B 1  and A 1 , B 1 -A 2 , B 2  are weighed in the ratio 1 : 2 to obviate ambiguities in the switching levels. The first threshold detector 16 compares the two levels A 1 , A 2  with the complementary level B 0  and provides a "1" level output corresponding to A 1  being greater than B 0  and A 2  being less than B 2 . The second threshold detector 17 provides an output when A 0  is greater than B 2  and A 0  is less than B 1 . The output from OR-gate 10c is thus at one level when an even number of "1" level inputs are present at W, X, Y, Z and is at the other level if an odd number are present.

Abstract: 1,096,813. Transistor switching circuits. MINISTRY OF DEFENCE. Nov. 10, 1965 [Nov. 10, 1964; March 23, 1965], Nos. 45703/64 and 12316/65. Heading H3T. [Also in Divisions G1 and G4] Gating circuits (Fig. 4).-A negative-going signal applied to R52 is transmitted to the line 55 provided it occurs after a positive signal is applied to R53. With no signals applied to R52 or R53, T29 is off and T30 is on. If the negative signal is applied to R52 when no signal is applied to R53, T29 is switched on, and the voltage on line 55 is limited to that developed across T29 and the non-linear diode D12. If then a signal is applied to R53, the current drawn thereby is smaller than that through D12 and so has little effect on the voltage on line 55. If, however, the positive signal is applied first, both T29 and T30 are off so that when the negative signal is applied to R52, it appears substantially unattenuated on 55 since the leakage current through T29 is small. Comparator circuits (Fig. 3).-The signals applied " FROM T8 " and " FROM 16 " are compared by feeding them to transistors T23, T24 respectively, the bases of which are pulsed alternately by interlaced pulse trains on lines A and B. The A.C. signal thereby developed across R40 is indicative of the difference between the applied signals and so long as this is large enough to make T26 and D9 conduct alternately. Conduction of T26 makes T27 conduct to transmit pulses " TO Q1." When the signals are substantially equal, T26 does not conduct, and no more pulses are transmitted " TO Q1." After 20 msec. a signal " FROM 21 " enabling T23, T24 and T27 ceases and a signal " FROM 20 " which has been delayed by the network C1, R38, R39, T20 enables T21, T22 and T28 so that signals " FROM 18 " and " FROM 40 " can be compared in the same way to control pulses applied "TO Q1."

[Also in Division B8] Apparatus for receiving and assembling pairs of components, e.g. cope and drag mould boxes, comprises a rotatable frame 18 that receives the cope and raises and inverts it, a conveyer 46 that receives the drag and raises it to the cope for alignment therewith, and means for releasing the cope from the frame 18 so that the cope and drag can be lowered on the conveyer 46 for onward conveyance. The incoming cope is supplied from a conveyer 9 on to rollers 21 to slide into a carrier 26 positioned in the U-shaped frame 18. The carrier 26 is movable transversely within the frame 18 by means of rollers 24, 25 and bearing surfaces 22, 23. The cope pivots a lever 33 which operates a first power means, comprising a pair of successively operated rams (15), (19), (Fig. 4, not shown), to pivot and raise the cope above the conveyer 46. The carrier 26 is positioned transversely in its raised position by the rollers 25 acting on cam faces on the framework of the apparatus. When the cope is raised a removable stop is raised on the conveyer 46 against which the incoming drag abuts. The drag is guided by guides 48 on the conveyer 46 and cams and rollers ensure the correct position of the conveyer 46 in its lower position. The conveyer 46 is raised by a ram (41) (Fig. 3, not shown) and is guided laterally by cam plates (57). Rotational alignment of the drag is provided by a limited rotational movement of the cylinder of the ram 41. When the cope and drag are aligned and closed together a further ram (58) moves them slightly to release the cope from engagement with the carrier 26 so that they can be lowered. The rollers 21 and conveyer 46 in its lower position are inclined for gravity feed, and as the conveyer 46 is lowered rollers 52 engage abutments 54 to tip the conveyer to its correct inclination.
