Title: Improvements in knurling heads for use with lathes and the like
IPC: B23B27/24
Filed: 1946-08-20
Abstract: 615,056. Knurling. BROWN, R. T. A. Aug. 20, 1946, No. 24858. [Class 83 (iv)] A knurling-head includes setting means for simultaneously adjusting the knurling-wheels in a radial direction and means operable independently of the setting means, whereby the wheels can be shifted radially outwards to release them from the work and returned inwards to re-engage the work at their previous position as determined by the setting means. Each knurling-wheel 13 is carried by a mounting 12 slidably mounted in a radial channel 11, and to each mounting 12 is pivoted a lever 17 urged outwardly by a compression spring 18, the free end of each lever 17 lying between and in contact with the cam ridge 21 of a setting ring 19 and the cam drum 22 of a disc 20, Fig. 4, both ring 19 and disc 20 being independently rotatable within the casing 1 by means of levers 24 and 25, which may be locked in position. In operation the knurling-wheels are adjusted to suit the work, with the free ends of the levers 17 resting on the rises of the cam drum 22, by rotating the setting ring 19 so as to bring a higher portion of the cam ridge 21 to bear against the levers 17 until the wheels grip the work. Having completed one knurling operation the wheels may be freed by rotating the disc 20 until the flats of the cam drum 22 come under the lever ends, thus permitting the springs 18 to force the mountings 12 outwards. To knurl a piece of work of the same size, the lever 25 is returned to the position in which the rises of the cam drum 22 contact the levers 17 and the wheels move inward to the same position as before. A scale may be marked against the slot in the casing 1 through which the lever 24 projects. In a modification, a cone, sliding axially takes the place of the cam drum 22. In a further embodiment, the mountings for the knurling-wheels move radially in channels of circular section and have pivoted to them L-shaped rockers 36, 37 and 38, Fig. 7, each mounting being urged outwardly by a blade spring 36A into contact with the setting ring 40.

Title: Improvements in the manufacture and production of polymerisation products
IPC: C08F36/04
Filed: 1930-08-21
Abstract: In the polymerization of diolefines in emulsion, the process is arrested when the amount of polymerizate soluble in benzene attains a maximum; this usually occurs when from 20 to 30 per cent of the diolefine remains unpolymerized.  Other polymerizable compounds may be present, such as styrene, vinyl compounds, esters of acrylic acid, methylene methyl ethyl ketone (C2H<5>,CO,CH : CH2) or polymerizable fats or oils or their derivatives such as linseed or China wood oils; also hydrocarbons other than diolefines, alcohols, ethers, esters, and acids, particularly higher fatty acids.  Catalysts such as oxygen, hydrogen peroxide, benzoyl peroxide, ozonides and the like and also colloidal substances such as albumenous substances, natural or synthetic resins, and rubber may be employed and the process may be terminated by coagulation by means of acids, or, if it is desired to obtain the product in the form of a latex, a substance may be added which has a decomposing or reducing action on the catalyst. The temperature may be 10-20 DEG  C.  In Examples (1) butadiene is emulsified in a closed vessel with ammonia, water, olein, and hydrogen peroxide, the temperature being 20-25 DEG  C. for the first 2 days, and then 20 DEG  C.; after 4 days the pressure is released and the mixture coagulated by an acid, 30 per cent of the butadiene being recovered; (2) in a similar process the product is stabilized as a latex by adding aldol naphthylamine and then coagulated with acids; (4) a mixture of butadiene and styrene is emulsified with oleic acid, ammonia solution, and hydrogen peroxide at 50 DEG  C. for 92 hours, the excess of butadiene being removed by releasing the pressure; (6) butadiene and isoprene are emulsified with oleic acid and ammonia solution and polymerized at 60 DEG  C. for 5 days; half the emulsion is coagulated with acetic acid, the product being soluble in benzene; if the rest of the emulsion is further polymerized for another 5 days at 60 DEG  C. the product only swells in benzene.  Specifications 323,721 and 333,894, [both in Class 2 (iii), Dyes &c.], are referred to.

An exchange includes a first translator which determines the class of service to which a calling party is entitled and transmits a corresponding signal to a register siezed for the call. The register transmits this signal and the route determining digits of the called number to a second translator which determines whether or not the desired call is allowed and controls a marker to set up the call if allowed or connects to an operator or returns busy if the call is barred. The first two dialled digits are connected to the translator over conductors a1 ... a0 and b1 ... b0, and one of each of the sets of relays B1 ... B5 and AB1 ... AB5 is energized to indicate the classes of calls the calling subscriber is allowed to make under normal and exceptional circumstances respectively. All subscribers may make local calls (1st digit 2 ... 8) and have access directly to directions II ... VIII. Certain special services (1st digit 1) are not available to subscribers for whom B 1 is up since contact b11 diverts earth on al to pull up Bs and return busy tone to a subscriber attempting such a call. Other classes of call are similarly barred to underprivileged subscribers by the operation of the contacts of relays B1 to B5. Under exceptional conditions particular classes of call may be barred to all normal subscribers by energization of relays Sp1 ... SpY. This barring is over-ridden for subscribers having an exceptional right-of-way by operation of one of relays AB1 ... AB5.
