Abstract: 367,749. Coating metals. WESTING- HOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London. -(Assignees of Ackerly, D. G. ; 804E, Hutchinson Avenue, Edgewood, Pennsylvania, U.S.A.) Aug. 19, 1930, No. 24806. Convention date, Sept. 11, 1929. Void [Published under Sect. 91 of the Acts]. [Class 82 (ii).] A rectifying element of the kind described in Specification 257,305, [Class 82 (ii), Washing granular &c.], comprising a copper body having a layer of cuprous oxide formed directly thereon, has a coating of metallic copper formed on the oxide coating by immersing the oxidized copper body in a bath of a fused inorganic salt. The copper blank is oxidized by heating to 1000 C. in an oxygen atmosphere and is then placed in an electrolytic bath containing an inorganic salt to reduce the outer layer of copper oxide to copper. One of the salts in this bath should be calcium chloride. The temperature of the electrolyte should be from 500 to 600 C. The treated blank, when in the electrolyte, should be in contact with a piece of iron or other metal having a higher potential than copper in the electromotive series. The iron becomes the anode and the oxidized blank the cathode, no outside source of potential being required. The blanks are then quenched in water. In an alternative process, the blank, after oxidation, is placed in a bath of molten metal, such as lead at 500-600 C., to reduce the outer layer of the oxide to copper.

Abstract: 189,901. Conners, E. R. Sept. 19, 1921. Disc apparatus; trueing rotating tools.-A trueing-device 116 is shown in Fig. 1 applied to a grinding-machine having a rotary work-table 108 and a grinder 29, which is reciprocated axially on a frame 11. Power is supplied through fast and loose pulleys 36 to a shaft 34, and thence by a belt 32 to a long pulley 31 on a shaft 27, which is journaled in a reciprocating carriage 25 and has the grinder 29 releasably secured thereto. A shaft 43 driven through gears 41, 42 has a clutch-collar 47 splined thereon and adapted to engage either a gear 45 or a gear 46 loose on the shaft 43. The gear 45 meshes with a gear 65 and the gear 46 with an intermediate gear 61, which in turn meshes with a gear 62. The gears 62, 65 are fast on a shaft 63 and, according to the position of the clutch-collar 47, the one or the other serves to traverse the carriage 25 through the medium of a gear train 71, 72, 75, 76 and a rack 77 on the carriage. Adjustable tappets 56, 57 on the carriage alternately contact with a lever 51, which has a forked end engaging the clutch-collar 47, and reverse the direction of movement of the carriage. A handle 80 serves to move the carriage when the clutch-collar is disengaged from both the gears 45, 46. The work-table 108, surrounded by a trough 109, is carried by a spindle 101 journaled in a bracket 103, which is vertically adjustable by means of a hand-wheel 21 and a screw 14 threaded in a bearing 15 rigid with the frame 11. The table is rotated through gears 81, 82, a clutch-collar 85 engaging the latter and splined on a shaft 83, a bevel-gear 91 on the shaft 83, and a bevel-gear 92 splined on the spindle 101. When the clutchcollar 83 is disengaged from the gear 82 and engaged with a member 84, the table is prevented from rotating. The table may be in the form of a magnetic chuck. The trueing-device is formed with a pedestal 161 having a slotted base adapted to be held magnetically on the magnetic chuck or bolted to a non-magnetic work-table. A shaft 121, Fig. 7, carrying an abrasive wheel 116 and a fly-wheel 148 is journaled in ball bearings in a bushing 124 which is secured within a barrel 123 upon the pedestal 161. The rim of the fly-wheel 148 surrounds the adjacent ball bearings and is located within a casing 122. A felt washer 138 is located between the abrasive wheel 116 and the adjacent ball bearings. When the grinder is to be trued or dressed, the trueing- device is mounted on the work-table in angular relation to the grinder according to the coarseness of dressing required, and the grinder is rotated and reciprocated so as to contact intermittently with the abrasive wheel 116, which is normally quiescent but which is rotated by contact with the grinder, the rotation being maintained and equalized by the fly-wheel. Specifications 161,073 and 189,277 are referred to.

Filed: 1937-09-13
Abstract: 503,957. Thermal switches; time switches. RAMSEY, A. R. J. (Automatic Control Corporation) Sept. 13, 1937, No. 24925. [Class 38 (v)] [Also in Group XXXV] A thermostatic switch comprises a bimetallic coil 30, Figs. 4 and 6, attached at its inner end to a sleeve 29 and at its outer end carrying a switch arm 31 provided with a contact 32 co-operating with an adjustable contact 55. Snap action is obtained by a permanent magnet 61 co-operating with an armature 33 on arm 31 and the differential effect produced thereby is partially compensated by anticipating heater 72. Setting is adjustable by turning of sleeve 29 through movement of member 35. This member is adjustable at its lower end 37 by manually operated cam means 38 to vary the temperature setting. The upper end of member 36 can be adjusted by a cam 52 so that the thermostat is operative at a lower temperature for a period of time (e.g. during the night) dependent on the angle through which the cam 52 is adjusted by the handle 80. Such adjustment causes closure of contacts 98, 99 through which an electromagnet 94 is intermittently energized from the time switch 132, each energization causing a pawl on member 86 to turn, a ratchet wheel 85 secured to the cam 52, by one tooth. The time switch comprises a pair of adjacent cam discs 145, 146, Figs. 9 and 10, driven by an electric clock 111 at one revolution per hour and adjustable so that the composite cam surface provided thereby has one or two notches 152, 153 in its circumference so that switch 137, 138, 139 is closed once or twice per hour for a tune adjustable by screw 162 and hand wheel 164. The inner cam disc 145 is provided with a number of pegs 168 cooperating with a member 170 shaped as shown and slidably pivoted at 180. Engagement of a peg 168 with abutment 186 on member 170 produces a momentary rotary lifting movement of this member whereby contacts 133, 131 meet momentarily with a wiping action to energize the magnet 94.

Abstract: 617,224. Pistons. RICARDO, H. R., HOLT, G. -A., and WATTS, R. Aug. 21, 1946, No. 24994. [Class 122 (i)] [Also in Group XXVII] Relates to cooling of a trunk piston of the kind wherein oil is delivered into the piston interior from the end of a hollow connecting rod. As shown, a trunk piston comprises a crown A, Fig. 1, from which projects a skirt B carrying gudgeon-pin bosses D and within the piston is formed a trough F comprising an inwardly extending wall C and an axially extending lip E terminating short of the crown so as to leave a slot through which oil from the connecting rod can enter the 'trough and through which surplus oil escapes to the open end of the skirt; the trough is partitioned by two or more walls D<1> extending axially between the crown and the trough and the cooling oil washes thereover. Part of the oil escaping from the trough F drains down ducts G to the gudgeonpin boss bearing surfaces and the rest is deflected by an inner skirt C<1> down the exterior of the connecting rod. In a modification, the lip and inner skirt are formed by a tubular member E<1>, E<2>, Fig. 5, bolted to the wall C<2> and in a further modification the lip E, Fig. 8, is conical and an annular projection A<1> extends from the crown A to form an inverted trough A<2>. Alternatively, the inner face of the crown may be formed with a cusp-like projection located centrally or eccentrically of the piston axis. Inwardly projecting ribs M also assist cooling.

Title: Improvements relating to the treatment of rubber
IPC: G10D9/06
Filed: 1931-09-07
Abstract: The vulcanization of rubber is controlled to avoid scorching &c., by incorporating, in addition to an accelerator, an acidic retarding agent, and at any time before or during vulcanization nullifying the retarding effect by treatment with ammonia.  As examples of acidic retarders, are organic and inorganic acids, acid salts, heavy metal salts of strong acids, acid anhydrides, acid chlorides and the like, the following being specifically mentioned:-sulphuric, phosphoric, hydrochloric, o-chlorobenzoic, o-nitrobenzoic, salicylic, acetic, mono-chloracetic, dichloracetic, trichloracetic, sulphanilic, b -naphthalene sulphonic and picric acids, dinitro-phenol, b -naphthalene sulphonic chloride, p-toluene sulphonic chloride, phthalic anhydride, sodium acid sulphate, monosodium phosphate, zinc chloride, zinc nitrate, mercuric chloride, stannous chloride, calcium chloride, magnesium chloride, aluminium chloride, ammonium chloride, ammonium nitrate and the like.  The accelerator used may be of the "ultra" or "semi-ultra" types such as thiuram disulphides, thiuram monosulphides, and mercapto thiazoles or such as dithiocarbamic esters and aldehyde-amines, but should be of such a character that ammonia will co-operate with or allow activation during vulcanization.  Accelerators excluded are those which are inactivated by ammonia such as oxy - n - butyl thiocarbonic acid disulphide. Twelve examples are given showing the results obtained with various mixes, including cr<\>zepe and sprayed rubber.  In one example latex containing ammonium phosphate is spray dried whereupon some ammonia is liberated leaving spray dried rubber containing a mixture of the two acid phosphates and some free phosphoric acid.  This is then incorporated in an accelerator containing mix and vulcanized in a mixture of air and ammonia.  Specifications 218,247, [Class 70, Indiarubber &c.], and 340,573 are referred to.

Title: Touch control switch circuit with compensation for power supply line fluctuations
IPC: H03K17/96
Filed: 1977-06-16
Abstract: 1533834 Touch responsive switching systems W F HAMILTON 16 June 1977 [16 June 1976] 25204/77 Heading G1N In a hum type pick-up touch switch false switching due to mains supply variations are obviated. In Fig. 1 reference detector 20 produces an output signal at 28, proportional to the amplitude of the A.C. line signal on 26, which is fed as a reference signal to comparator 54. Thus a change in the amplitude of the line signal which also produces a  change in true signal picked up by touch plate 30, will not produce a false switching since the two signals applied to the comparator inputs both change by the same amount. When the touch plate 30 is touched the pick-up signal at 56 increases, the signal at 54 remaining the same causing an increase in the voltage across capacitor 68 so that trigger circuit 24 changes state, the latter being operable in synchronism with the line signal. Sensitivity of the comparator is continuously updated by the feedback path including FET 60 connected as a shunt. In an alternative arrangement Fig. 3 (not shown) touch plate 30 is connected to a peak detector of the same form as 20 of Fig. 1 and the output thereof is connected to one input of a comparator. The other input of which is connected to the output of a similar peak detector to the input of which is connected the A.C. line. Alternatively Fig. 4 (not shown) the touch detector and reference detector use C-MDS invertors each detector being provided with a feedback and the output of the touch detector is connected to the D input of a trigger circuit to the reset input of which is connected the output of the reference detector. Thus a change in amplitude of the line signal causes the trigger circuit to be inhibited.
