Abstract: 576,559. Grinding pins ends against a roller. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. (Radio Corporation of America). June 2, 1942, No. 7463. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 30, 1942.] [Class 60] [Also in Group XXX] Short lengths of wire, heavy at one end (such as radio valve pins), are straightened, fed heavy end first to a grinding roller for pointing one end and delivered to a positioning collar. Wires from a supply hopper 6 fall on to a grooved shoot and pass a magnetized rubbercovered straightening roller 9 and plate 11 proceeding to a shoot 12 having a gap 13 to pass them heavy end first to funnels 14. The wires pass thereby to tubes 15 having stops 24 at the lower end and apertures shorter than the wires, which are picked therefrom by electromagnets 23 controlled by timing cams 25a and contacts 25 and delivered to tubes 15a secured on a shaft 18 rocked in synchronism with the cam 25a between stop bars 26, 27. Each tube 15a has its lower end positioned with respect to a grinding roller 16 so that it presents the wires one by one thereto at such an angle that a cone point is ground on the wire. The tube 15a is then tilted to deliver the wire to a conduit leading to a stationary guide collar 21 aligned with the work-piece which is to receive the wires.

Title: Nmr detection methods and apparatus

Abstract: 1,216,861. Measuring fluid-flow. BADGER METER MFG. CO. Feb. 19, 1968 [Feb. 20, 1967; Oct. 9, 1967], No.7937/68. Heading G1N. The invention relates to flowmeters of the type wherein the rate of flow of a fluid containing gyromagnetic nuclei is measured by polarizing the nuclei in a bolus of the fluid at a tagging station 12 and detecting the arrival of the bolus at a nuclear magnetic resonance detection station 14. Each output pulse from the detector may be used to generate a new tagging pulse whereby a metered quantity of fluid is indicated by each pulse and the total flow during any time interval is proportional to the total number of pulses during that interval. In accordance with the invention, there is provided at the detection station a uni-directional magnetic field H 0  and a radio frequency field of constant amplitude H 1  and frequency f transverse to the uni-directional field, and a gradient is established along the flow path in one of these fields to cause a slow adiabatic rotation of the direction of the effective field (the vector sum of H 1  and Ho - 2#f/γ where γ is the gyromagnetic ratio of the polarized nuclei) operating on the polarized nuclei relative to a co-ordinate system rotating about an axis parallel to the uni-directional field with a frequency f. As described with reference to Fig. 1, a gradient is established in the uni-directional field H 0 . Coil 22, coaxial with the flow path, picks up the resonance signal which occurs when the polarized nuclei reach a point in the flow path where Ho = 2#f/γ . In an alternative embodiment, Fig. 7 (not shown), not subject to errors due to fluctuations in r.f. frequency, the uni-directional field H 0  is uniform and a gradient is provided in the r. f. field H 1 . The r. f. coils and pick-up coil may be located centrally of the uni-directional field or at the downstream end thereof. The frequency f of ther. f. field is chosen such that H 0  >> H 0  - 2#f/γ >>H li  where H 11  is the amplitude of the r.f. field as the nuclei enter the detection station. A suitable value for f satisfies the relation 2##/H 1  = À02 (where #f is the deviation in cycles per second from the Larmor frequency) for a fluid having a longitudinal relaxation time of about 1 second and flowing at 10ft. /sec. with H 1  equal to À5 gauss at the centre of the pick-up coil.

[Class 4.] An accelerating device for flying machine launching tracks comprises a piston 2 working in a cylinder 1 under fluid pressure action and is characterized by the provision of means operated by the piston which allow a reduced pressure only to act on the piston during the initial part of its motion. The cylinder has at its head a reduced section through which the pressure fluid such as air or the combustion products of a gaseous or other explosive is admitted. In one form, Fig. 1, the reduced section is obtained by the use of a head 4 provided with a removable ring 3 through which projects a tapered extension 5 secured with limited freedom of movement to the piston 2. The pressure fluid acts initially only on the extension but as the piston is forced downwardly the pressure in the cylinder increases acting on the whole of the piston area when the latter has moved sufficiently to withdraw the extension 5 completely. In another form an automatic valve 7, slidably mounted on a spindle 10 having a guide 11 in the reduced part of the cylinder, is urged against a seating in the cylinder head by means of a spring 8 the tension in which is reduced as the piston advances on its stroke.
