Abstract: 995,776. Impulse transmitters. GENERAL ELECTRIC CO. Ltd. Nov. 8, 1963 [Dec. 10, 1962], No. 46496/62. Heading H4K. In an impulse transmitter in which the impulses are generated by contacts during the return of a rotatable member from a selected position to a rest position, the rotatable member has a plurality of teeth projecting parallel to its axis and engaging part of a pivoted member, the teeth being of such shape that the pivoted member is moved away from the contacts during the forward motion and towards the contacts during the return motion. As shown, Fig. 1, a rotatable member 3 is provided with teeth 4 and is mounted coaxially with a finger plate (not shown) which can be moved from a rest position against the force of a return spring. An arm 22 is joined to the finger plate and a pin 23 engages a slot 21 in member 3 to provide a lost motion drive. A member 7, pivoted at 8, is provided with a pin 9 which projects into the path of the teeth 4. When the dial is set the inclined edges 67 of teeth 4 engage pin 9 and move member 7 inwards. When the dial is released the spring drives member 3 and the faces 70 of teeth 4 engage pin 9 and move member 7 outwards to engage a set of impulsing contacts 24 and generate the required impulses. Off-normal contacts 32 are arranged to be opened by the engagement of slide 41 by arm 22 in the rest position. A governor 17 is provided and is driven by a gear train connected to the finger plate. Arrangements for use in coinoperated telephones include a spring 30 with a projection 31 which engages a part 66 of member 3 having a reduced radius. Normallyopen contacts are provided which are closed only if a digit other than " 1 " is dialled. Further contacts (not shown) are provided which are actuated by a cranked member mounted on the same shaft as member 3 and arranged so that the contacts are opened when either of the digits " 9 " or " 0 " is dialled and remain open until the dial returns to its rest position. Arrangements are described for replacing a cog in the governor gear train by a smaller one to double the pulse repetition frequency. In an alternative embodiment the member 3 may be driven by a reversible electric motor controlled by an information store so that a complete number may be dialled by pressing a button.

Title: Impulse tool
IPC: B25B23/145
Filed: 1964-11-17
Abstract: 1,023,088. Nut runners. THOR POWER TOOL CO. Nov. 17, 1964 [Nov. 22, 1963], No. 46838/64. Heading B3N. A nut runner comprises a reversible rotary air motor 26 controlled by a throttle valve 28 and an impulse unit 31 mounted in a casing 21 and including an output spindle 32. Unit 31, Figs. 5, 6 (not shown), comprises a housing assembly 41 driven by motor 26 at 73, and an internal spindle 42 having the portion 32 projecting therefrom. Assembly 41 includes an outer casing 43, a bushing 47 having an elliptical bore 48 and end caps 49, 51. Spindle 42 has a cylindrical centre portion 62, and a short stub shaft 63 journalled in cap 51. Bore 48 is filled with oil or the like through a plug 71, and has a pair of circumferential recesses 81 interrupted by lands 82, 83. Spindle portion 62 has four radial slots 86 each of which slidably supports a spring-urged blade 87, and the slots are enlarged to form bores 88. Each bore 88 communicates with the outer periphery of spindle portion 62 through a pair of passages 89 in the spindle. In operation, assembly 41 is being driven in a counter clockwise direction, and a nut is being tightened. The frictional engagement of blades 87 with bore 48 is sufficient to cause spindle 42 to rotate in a counter clockwise direction. When the torque resistance increases as the nut is tightened, assembly 41 rotates relative to spindle 42, and as the oil in bore 48 is free to flow through recesses 81, the pressure in the bore is uniform. As assembly 41 continues to rotate, lands 82, 83 are aligned with blades 87, Fig. 8 (not shown), and blades 87a, 87b are forced into their slots 86. The inner edges of blades 87c, 87d are in communication through passages 89, 88 and fluid passes between zones 95<SP>1</SP>, 95 to maintain the uniform pressure. When the Fig. 9 (not shown) position is reached, zones 95<SP>1</SP>, 95 are no longer connected, and pressure builds up in zone 95, to thus provide an impact on the spindle, which is repeated twice for each revolution of assembly 41. An adjustable pressure relief valve 109 is provided in the spindle and is connected to the HP and LP parts of bore 48. In a modification the valve 109 is mounted in the housing instead of the spindle. In a further modification bore 48 is circular, and the spindle has an elliptical cross-section, blades 87 being carried in slots in the housing.

A rotary flow-meter for indicating flow, rate-of-flow or total flow of a gas or liquid in a pipeline, comprises a tubular body part 1 housing an insert 3 which mounts a field winding 9 and a conical rotor 7 having magnetised blades 8 supported in upstream and downstream bearings 17, 6 carried by spiders 5. The upstream spider is formed at its centre with a shield 12 having a conical upstream face and a recess 13 on its downstream face into which the front face of the rotor can be accepted. A hole 18 and passages 19 in the shield allow pressure fluid to act on the front face of the rotor tending to urge the rotor downstream in opposition to the fluid pressure acting on the tapered rotor face tending to urge the rotor upstream. The parts are dimensional such that these fluid pressure forces together with the drag on the blades 8 move the rotor to an equilbrium position in which thrust on the bearings is eliminated.

The parent Specification describes and claims macrocyclic polyethers containing at least 12 atoms in the polyether ring of which at least 4 are oxygen atoms and in which (a) each oxygen atom of the polyether ring is bonded only to carbon atoms and is separated from the next oxygen atom by 2 to 10 carbon atoms, (b) at least one pair of vicinal carbon atoms of the polyether ring is fused to an aromatic ring, and (c) each of the vicinal carbon atoms fused to the aromatic ring is bonded to an oxygen atom of the polyether ring. This invention is now modified in that, in so far as polyethers containing at least 14 atoms in the polyether ring and in which the oxygen atoms are separated by 2 or 3 carbon atoms are concerned, the vicinal carbon atoms mentioned above are fused to a fully saturated alicyclic ring instead of to an aromatic ring. The compounds may be prepared as described in the parent Specification, followed by catalytic hydrogenation to convert the aromatic ring into an alicyclic ring. Some of the examples describe the hydrogenation of products specified in the parent Specification. Others describe the preparation of products covered by the parent Specification but not exemplified therein, and the subsequent hydrogenation of these products. Like the products of the parent Specification, the products of the invention form complexes with compatible cations, and methods for preparing such complexes, and for utilizing the complex-forming property, are described, these methods being generally similar to those described in the parent Specification. The last two examples describe the preparation of complexes from certain products of the invention and potassium hydroxide, potassium iodide, potassium tri-iodide, ammonium thiocyanate and barium thiocyanate.
