Patent GB-161917-A (GB)
Abstract: 161,917. Bowen, R. S. April 17, 1920, [Convention date]. Rotary distributors; contacts.-A rotary distributor having an internal annular contact race is provided with a rotating contact brush in the form of a swinging lever, one end of which is constituted by an outstanding lug which rubs against the contact race. The outer casing 1 holds a raceway 2 of insulating material in which contacts 3 are embedded. A shaft 5 carries a bush 7, secured thereto by a pin 5a and a nut on'the threaded end of the shaft, the bush having two radially projecting lugs 8, which carry pivotally the rotating contact member 10. A pivot pin 11 passes through the lugs 8, 8 of the bush 7 and the arms 9, 9 of the contact member 10, one end of which is in the form of a lug d which serves as a contact brush. The leading edge a<1> is of concave form, concentric with the axis of the pivot pin 11, the leading lip a<2> being of V formation, thereby keeping the surface of the raceway clean. A helical spring 14 is wound round the centre portion of the pivot pin 11, its ends 14a and 14b acting between the bush and the contact member respectively. The shape of the leading face a<1> ensures a uniform time of ignition in all conditions of wear of the rotating contact member 10, and a lug 15 limits the wear on the contact member to the extent indicated by the dotted linex.

Title: A process for making synthetic polymer monofilaments of improved transverse properties and monofilaments provided thereby
Inventor: ARTHUR DAVID FOXALL
IPC: D01D10/04

Abstract: 1,037,935. Treating monofilaments with steam. BRITISH NYLON SPINNERS Ltd. April 13, 1965 [April 21, 1964], No. 16426/64. Heading B5B. An oriented monofilament of a synthetic polymer, particularly a polyamide such as polyhexamethylone adipamide is exposed to an atmosphere of saturated steam for a period of time which permits diffusion of water vapour into the monofilament to the extent that, only in the region of the monofilament adjacent the peripheral surface thereof, are the polymer crystals disoriented. The process is continuous and improves the transverse properties of the monofilament, as evidenced by resistance to abrasion and flexing. The atmosphere of saturated steam may be maintained at a pressure at which its temperature is at least as high as the melting point of the synthetic polymer in such an atmosphere. The monofilament may consist of polyhexamethylene adipamide and the atmosphere of saturated steam may be maintained at a pressure of at least 105 p.s.i. (gauge) corresponding to a temperature of at least 172 C. and the period of time during which the monofilaments are in contact with the atmosphere is 15 to 100 milliseconds. The monofilament may have a denier less than 83 and comprise an oriented core portion and a disoriented sheath portion, the latter, for example extending inwardly from the surface of the monofilament to a depth which is 5 to 30% of the radius of the monofilament.

An impact-wrench for screwing-up nuts &c., comprises a rotatable hammer, a dog-member slidably connected to the hammer for axial movement relative thereto and having one or more impact-jaws, a rotatable anvil adapted for connection with a driven member and having one or more impact-jaws, cam-means responsive to the rotary motion of the hammer to cam the dog-member into intermittent driving engagement with the anvil by way of the respective impact jaws, and yieldable or compression means to urge the dog-member away from the anvil. A shaft 24 projecting from a motor (not shown), preferably pneumatic, has a splined connection with a hammer 28. The forward end of the hammer is recessed to receive a dogmember 33 connected for axial movement within the hammer by a splined connection 34. The dog member is rotatable and slidable on a spindle 36 which is rotatable in the end of the motor-spindle, and at the other end fits into a bore in an anvil 48. The dog-member is forced to the right, against the hammer, by a spring 58 within the left-hand portion of spindle 36. Impact-jaws 40 on the dog member 33 correspond with similar jaws 69 on the anvil, but these clear one another in the non- impacting position of the parts, Fig. 1. The anvil is connected to a socket-wrench 72 &c., which engages the driven member such as a nut &c. The rear end of the dog-member has a pair of diametrically-opposite cam-parts 42, 43, Fig. 7, at different radii. Similar cam-parts 63, 64 on a cam-element 62 engage each 360 degrees with the cam-parts 42, 43. The cam-element 62 has a limited rotation relative to the shaft 36 through a pin-and-slot connection 67, the slots 66, Fig. 8, being wider than the pin diameter.
