Abstract: 1,187,630. Positive clutch control. MITSUBISHI JUKOGYO K.K. 25 Oct., 1967 [26 Oct., 1966], No. 48594/67. Headings F2C and F2L. In a synchronized positive clutch arrangement, wherein driving and driven shafts 1, 2 are substantially synchronized prior to engagement of a positive clutch 7, 4 therebetween, by engagement of a friction clutch 15 between shafts 13, 14 parallel to and respectively geared to the shafts 1, 2, the friction and positive clutches are successively engaged by manual operation respectively of hydraulic pressure control valves 66, 50; and valves 34, 35 responsive to sliding movement of the positive clutch sliding member 7 respectively disengage the friction clutch and reset and inoperatively lock the control valve 66 respectively during engagement and upon full engagement of the positive clutch. The friction clutch comprises discs 17, 18 engaged by a pneumatic servomotor 23 energized via a relay 67. The positive clutch is engaged by an hydraulic servomotor having a spring-biased piston 31. Gear pairs 9, 11 and 10, 12 between the shafts 1, 13 and 2, 14 are of slightly different ratio so as to provide a slight (5 R.P.M.) speed difference between the shafts 1, 2 in their " synchronized " state. A lever 30 has a first arm connected to the hydraulic servomotor piston 31, a second arm connected to the positive clutch sliding member 7, and a third arm respectively connected to the spool 38 of the valve 34 via a roller 37 and connectible to the spool 44 of the valve 35 via a lever 36. The control valves 66, 50 have push-button spools, each movable between two positions in which they are held by spring detents 57, 51. In operation, starting from the position shown, to engage the positive clutch, the spool of the valve 66 is pressed to connect, via the valve 34, hydraulic pressure to the relay 67 which in turn engages the friction clutch 15. Next, the spool of the valve 50 is pressed to vent the hydraulic servomotor to allow the piston 31 to be spring depressed and, through the lever 30, rightwardly move the positive clutch member 7. During this movement, first the end tooth faces of the clutch members 7, 4 slide on each other with a relative speed difference of, say, 5 R.P.M., and at this position of the lever 30 the valve 34 is spring-actuated to vent the relay 67 and disengage the friction clutch and, finally, when the clutch 7, 4 is fully engaged, the valve 35 is actuated to connect fluid pressure to the left-hand end of valve 66 to reset and lock the spool thereof in its position shown and keep the friction clutch disengaged throughout positive clutch engagement. To disengage the positive clutch, it is only necessary to pull back the spool of the valve 50 to re-energize the hydraulic servomotor to raise the spool 31 thereof and disengage the clutch 7, 4. During this disengagement, the valve 35 is spring-returned to release the hydraulic lock on the control valve 66, and the valve 34 is actuated to re-connect the valve 66 to the relay 67.

Title: Electrochemical cells and manufacture of electrodes therefor
IPC: C01B3/12
Filed: 1962-12-28
Abstract: An electrochemical cell, wherein H1 is evolved at the cathode or wherein a fuel gas is absorbed at the cathode to produce electrical energy, contains a cathode which comprises a support formed from Fe or steel, a portion or the whole of the surface of which is conductively covered by a coating of an alloy consisting of Mo and one or two of the metals Fe, Co and Ni or consisting of W and either Fe or Co or two of the metals Fe, Co and Ni.  The electrode may be used in the electrolysis of aqueous alkali metal halide to produce H2, Cl2 and caustic alkali or a chlorate or in the electrolysis of alkali metal iodide to produce iodate.  The electrode may be in the form of wire, tube, rod, planar or curved sheet, perforated sheet, expanded metal, foraminous metal, gauze, porous, compacted or fused metal powder.  Binary alloys of Mo/Co or Mo/Fe contain 5-70% Mo, of W/Co contain 5-66% W, of W/Fe contain 5-60% W, and of Mo/Ni contain 5-65% Mo.  Ternary alloys contain 5-60% Mo or W.  The alloy may be applied to the support by electroplating; by sintering a mixture of the powdered alloy metals under the application of heat, with or without pressure; by roll bonding; vacuum depositing; metal spraying or rolling the powdered alloy or a mixture of the powdered metals on to the metal sheet; or by painting a metallizing solution of the alloy on to a metal sheet and subsequently firing, where the metals of the alloy coating are applied in a finely divided form in an organic solvent resin system.  Prior to electroplating the Fe or steel support may be degreased and treated with HCl.  For electroplating W alloys, either WO3 or a soluble tungstate is used together with a salt of the codepositing metal.  Hydroxy organic acids, e.g. citric or tartaric, or their Na and K salts may be added to complex the Fe group metals, NH4Cl and (NH4)2SO4 may be added and some baths also comprise NaCl or KCl.  Mo alloy plating baths are similar to the W plating baths with MoO3 or a soluble molybdate replacing the analagous W compounds.  The pH may be adjusted with NH4OH or NaOH solutions. Some baths may contain Na4P2O7, NaHCO3 and N2H4.H2SO4.  Laboratory experiments using the electrodes are carried out in a glass vessel with a graphite anode and an interchangeable cathode separated by a permeable porous polyethylene diaphragm.

Abstract: 1369635 Boots, &c BRITISH UNITED SHOE MACHINERY CO Ltd 22 Oct 1971 [23 Oct 1970] 49153/71 Addition to 1310917 Heading A3B The shoe bottom roughing machine of Specification 1310917 which includes a forepart template portion Tl for guiding the roughing tools (not shown) in a "toe to breast-line" roughing operation, is modified by the addition of a heel template portion T2 to allow an "allround" roughing operation to be performed, both template portions T1, T2 being adjustable in width and being movable relative to each other to vary the length of the template assembly T so that a single template assembly T can be used for a range of shoe sizes in a given style of shoe. The machine of the parent Specfiication is further modified by providing a retractable hold-down member (not shown) of the type described in Specification 1,285,559 to allow an "all round" roughing operation to be performed. The heel template portion T2 consists of two sections 154, 155 which are pivoted to the template holder 130 by pin 175 and which are urged together by spring 161 until inner edges 158, 159 of the sections engage a stud 174. The inner edges 158, 159 form a wedge shaped opening. The stud 174 can be moved lengthwise by a piston and cylinder (not shown) to vary the width of the heel portion T2. The forepart template portion T2 consists of two sections 152, 153 which are pivoted at 151 to a baseplate 150 which can move lengthwise of the template holder 130. A spring 160 urges the inner edges 156, 157 of the sections 152, 153 into contact with a stud 162 fixed to the template holder 130. The inner edges 156, 157 form a wedge shaped opening. Thus movement of the base plate 150 together with the sections 152, 153 in a lengthwise direction varies the width of the forepart section T1 The base plate 150 and sections 152, 153 are moved lengthwise by the stud 174 (which varies the width of the heel portion T2) until the base plate 150 contacts a stop member 184 whose position is determined by the position of the toe support (not shown) and thus by the size of the shoe. Movement of the stud 174 therefore moves the toe portion T1 lengthwise according to the size of the shoe and also adjusts the width of both portions T1 and T2 according to the size of the shoe.

Abstract: 1,195,288. Detecting presence. WAGNER ELECTRIC CORP. Oct. 31, 1967 [Nov. 8, 1966] No. 49329/67. Heading G1N. In apparatus for automatically flushing a urinal when a user leaves, a relaxation oscillator is so arranged that in the absence of a person at the urinal, the voltage between earth and tap 17 due to current 28 discharging from the capacitance between a metal mesh 11 and earth through a neon lamp 14 is substantially equal and opposite to the voltage between the base of transistor 33 and tap 17 due to current 27 discharging from a fixed capacitance 19 between mesh 11 and a plate 10 whereby the base of transistor 37 is substantially at earth potential. In the presence of a person at the urinal, the capacitance between mesh 11 and earth is increased whereby current 28 increases so that a series of negative pulses is applied to the base of transistor 33. These pulses are amplified by transistors 33, 34 and cause a transistor switch 35 to become conducting to short out the energizing current of a relay 36, breaking contacts 57 and making contacts 54. Capacitors 70, 71 thereupon discharge through resistors 72, 73, 74 in about 12 seconds to block transistor 60. When the person leaves, switch 35 again becomes blocked, allowing relay 36 to be energized closing contacts 57 to energize a second relay 37 which closes contacts 64 to energize the flushing motor (now shown). After five seconds, capacitors 70, 71 have become charged and turn on transistor 60 to short out the energizing current for relay 37. A locking circuit 65 is provided to keep relay 36 energized while flushing takes place even if a person should return to the urinal within five seconds, so that flushing cannot occur more frequently than once every seventeen seconds. In an alternative arrangement, Fig. 6, mesh 11 is replaced by a pair of rods 83, 84 on either side of the urinal and connected to neon lamp 14 via the central conductor of a coaxial cable. The capacitance of the cable serves instead of capacitanc e 19 in Fig. 1. A plate 10A behind the urinal compensates for current flowing via the capacitance 92 between the rods and an earthed water curtain. Plate 10A may be connected into either current path, as required.
