Title: Improvements in brakes or clutches
Inventor: BUTLER HENRY JAMES
IPC: F16D13/75
Filed: 1959-01-22
Abstract: 935,640. Disc brakes. DUNLOP RUBBER CO. Ltd. Jan. 20, 1960 [Jan. 22, 1959], No. 2354/59. Class 103 (1). [Also in Group XXIV] A disc brake having automatic friction pad wear compensating mechanism comprising a nut 13 rotatable on the threaded end 11b of rod 11, which couples the friction element applying lever 3 on one side of the disc to a member 5, on the other side of the disc 1, which is pivoted at 3c the adjacent applying lever 3. In the member 5 is housed a fluidpressure piston 7 operative through rod 8 to pivot lever 3 to apply the friction elements 4 on the disc. A nut 13 may have a ratchet track 27 on the outer surface, which is engageable with a pawl 28 carried by a carrier 26 slidable on a spindle 19 and spring loaded from both the plunger end 18 and plug 24. As the righthand lever member 3 moves to the right on release of the brake, it acts upon the end of the stud 17 to pivot the thrust member 16 and cause movement of the plunger 18 so as to compress the lower coil spring 22 and the pawl 28 is moved to engage a tooth on the track 27 and rotate the nut 27 through a small angle and cause an adjustment in the clearance of the brake friction elements. In an alternative construction, a spring clutch 21 encircles the nut and the free end is attached to a ring which replaces the carrier 26. When the ring is moved the spring 21 grips the nut and turns it. The unit 13 is encircled by spring clutch 25, one end of which is anchored so as to cause it to prevent rotation of the nut on shaft 11 in the reverse direction.

Abstract: 1425522 Pigment compositions containing azoarylamides CIBA-GEIGY AG 31 Dec 1973 [17 Jan 1973] 2361/73 Heading C4P A pigment composition comprises an azo pigment and a compound of the formula wherein A is an optionally substituted aryl or heterocyclic radical; R, R 1 , R 2  and R 3  are each H, C 1-7  alkyl, a C 5-6  cycloaliphatic radical, C 7-8  aralkyl or C 6-8  aryl, or R 1  and R 2  together with the C atom to which they are attached form a C 5-6  cycloaliphatic radical, or either of R 1  and R 2  together with R and the N atom to which it is attached form a 5- or 6-membered ring; Y is -CO 2 H or -SO 3 H and is attached to R 1 , R 2  or R 3  or directly to the C atom bearing them; m is zero or 1; p is 1 or 2 ; aud n is 1 or 2; and the total number of C atoms in R, R 1 , R 2  and R 3  does not exceed 9. The composition is prepared by coupling, under essentially aqueous conditions, one or more diazo or tetrazo compounds of the formula where hal is a halogen atom with one or more first coupling components BH where B is the coupling component residue and a minor proportion by weight of a second coupling component of the formula This process may be effected stepwise, e.g. by coupling with the first coupling component then adding the second or by coupling with the first and then adding the product of coupling the diazonium salt with the second, or by reversal of the order of coupling, but the process is preferably effected by coupling a mixture of the two coupling components with the diazo or tetrazo compound. With the use of a tetrazo compound the resulting composition has the following constituents Preferably the second coupling component is used in an amount of 1-10 wt. per cent calculated on the total wt. of coupling component used. Coupling may be effected for instance at temperatures of - 10‹ to + 50‹ C. and at a pH of 1-6. It is normally advantageous to add during or after the process an amount, e.g. 1-40 wt. per cent based on the wt. of the total composition, of one or more agents known to improve the application properties of a pigment, such as rosin, a zinc/calcium resinate, an amine or a derivative of an amine. If the agent is added after the coupling process the addition may be accompanied by heating. The compositions may be used for colouring inks, paints and varnishes.

The electrolyte may be the same in all compartments e.g. 0À1-16M HNO 3  and 0À01-0À1M Co (NO 3 ) 2  with a trace of NO<SP>=</SP> 2  added to the catholyte. A c.d. below that which produces NH 3  and which yields HNO 2  as main cathode product is preferred e.g. below 3.6 x 10<SP>-2</SP> A/cm<SP>2</SP>. The cell partition(s) (which may form a central compartment) may be Al 2 O 3  or fritted glass. Catholyte or intermediate compartment electrolyte may be maintained above the anolyte level. Several cells in series may be arranged with countercurrent gas/anolyte streams. The process also removes NO 2 . Retroactive current control may be effected via a reference electrode.

Title: Improvements in and relating to arrangements for controlling the speed of a turbo-generator for electrical networks having mainly ohmic loading
IPC: H02P9/42
Filed: 1947-01-29
Abstract: 650,770. Automatic voltage control systems. AKT.-GES. BROWN, BOVERI, & CIE. Jan. 29, 1947, No. 2796. Convention date, Feb. 7, 1946. [Class 38 (iv)] In a control system for a turbo-alternator supplying a mainly ohmic load, output voltage is automatically varied in dependence on and in the same sense as frequency to obtain a speed-torque characteristic suited to the turbine. For stable operation of a turbo-alternator 2, Fig. 2, supplying a mainly resistive load 1 an inductance 6 in series with the operating coil of an automatic voltage regulator 4 acting on the field of an exciter 3 causes the load voltage to rise with increase of frequency corresponding to an increase of speed and vice versa, the consequent change in load opposing the change in speed. In Fig. 3 this effect is produced only while speed is changing, by two opposed D.C. coils 9 and 10 operating on a voltage regulator 8. A resonant circuit 13, 14 produces the voltage change with change of frequency and a series condenser eliminates the effect of coil 10 under static conditions. Coil 10 may directly influence the alternator field or control a transformer associated with the alternator output.

A genuine coin 11 is received in a slot 10 in the disc 1 and lifts a pawl 12 out of a slot 14 in the disc 2 so that the two discs can rotate together and, through a pinion 27, rotate a bottle-storage drum. The coin 11, as it is carried round, falls from the disc 1, or may 'be pushed out by a bell-crank lever pivoted by the pawl 12 and, after a complete revolution of the discs, the pawl 12 again engages the slot 14. A second pawl 16 engages ratchet teeth on the disc 2 to prevent reverse rotation of the discs. Article delivery. - Bottles 24 or other commodities are supported in horizontal columns between partitions 25 in a drum and, as the drum is rotated by the pinion 27 and a gear 28, the lowermost bottles in the columns move over arcuate tracks 26 that slope down towards a delivery shoot 30 ending in a weighted pivoted flap that prevents the delivered bottle from falling completely through the open end of the shoot. As a bottle is delivered, the bottle immediately above passes on to a plate.32 that temporarily supports the column. Coin-slit closing.-A finger on a connecting rod (not shown) projects into the bottle compartment when the supply of bottles is exhausted, or, particularly in the case of a refrigerated machine, when only one row of bottles remains, and operates a link mechanism to close the coin slit 4. Change-giving.-A cam track 18 or eccentric on the disc 1 pivots a lever 19 so that a slide 20 ejects a change coin 21 from a stack into a shoot 22.
