Title: Improvements in or relating to rotary electric machines
Inventor: RAWCLIFFE GORDON HINDLE
IPC: H02K19/32
Filed: 1960-02-26
Abstract: 974,082. Pole-changing in dynamo-electric machines. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 8, 1961 [Feb. 26, 1960], No. 6821/60. Heading H2A. In a salient-pole field system for a change-pole synchronous machine a compromise non-uniform pole-width and pole-spacing is employed for both pole-numbers. The conversion from one pole-number to the other is made by reversing half of the poles in known manner, this operation combining the opposite poles 5, 6 and 10, 1 of the ten-pole condition to leave only eight poles. These poles are narrower than the others to reduce the excessive width when combined. The result is that neither pole-number is perfect but its harmonic content is less than that produced in modulating a regular pole arrangement. The inherent irregularity produced by pole-changing is divided between the two pole-numbers, in that the ratios between the pole-widths are about equal in each case. The required irregularity may be achieved solely by suitable dimensions and positions of the pole-shoes, the pole-bodies being of uniform spacing and width. The invention may be applied to the P.A.M. machines described in Specifications 900,600 and 926,101.

Abstract: 1459293 Battery terminal connections GLOBE-UNION Inc 15 Feb 1974 [14 March 1973] 7005/74 Heading H1B [Also in Division B3] In making a battery terminal connection through an opening in a wall of the battery box a first metallic member is positioned on one side of the wall, an extending portion of the member being positioned in the opening to project to the other side of the wall, a second metallic member is placed over the extending portion of the first member, the contacting portions of the first and second members are fluidized and the portion of the wall between the members is rendered plastic, by applying a force to the members and applying a welding current through the members while maintaining the force, the current is terminated, the force is released, the heated portions are allowed to cool and the members are forced together with said portion of the wall therebetween. In an embodiment a hole is punched in a plastics wall of a battery case leaving an annulus 12 Fig. 2 around the opening 14. A front member 15 cast from an antimony lead alloy with a steel nut embedded therein has an extending portion 16 which is placed through the hole 14. A back member 18 of the same alloy has a compartment 19 which is frictionally engaged with the end of the portion 16, but before fitting the member 15 an annular wax or other thermoplastic material bead 20 is provided on the portion 16. Welding current is then passed through the assembly while pressure is applied to the members to melt the adjacent areas of the members and to render plastic the wall around the opening. A lower initial pressure may be applied before the current is applied and a higher pressure is then applied and continued after current is terminated. Alternatively the current and pressure may be applied at the same time. The members are allowed to cool (e.g. for 2 mins.) and are pressed together with a forging pressure with plastic wall between them. A preferred back member 18 Fig. 11 is provided with a recess containing a hemispherical projection 29 and a lug 24 upstanding from a battery plate 41 has a projection 28 to fit into the recess over the projection 29. The back member 18 is then resistance welded to the lug 24. A conveyer for conveying the battery box carrying the welded members to a hydraulic ram means is provided on a swaging machine for mechanically upsetting the welded members.

Abstract: 1,154,677. Semi-conductor devices. MOTOROLA Inc. 13 Feb., 1968 [15 Feb., 1967], No. 7032/68. Heading H1K. A buried high conductivity layer 16 is formed by diffusion of antimony into, for example, a P-type silicon substrate 10 and by the subsequent growth of an epitaxial layer 17 on top of the substrate. The antimony diffusion is effected by depositing antimony as oxide or silicate on to a silicon oxide masking layer (11) and then covering the antimony layer with a further silicon oxide layer (15) so that antimony does not escape during the diffusion step which is carried out in an oxidizing atmosphere. After diffusion, oxidic material is removed from the surface which is then cleaned to receive an arsenic doped N-type layer 17 formed by hydrogen reduction of silicon chloride. The epitaxial layer may be passivated by growth of an oxide layer 18.

IPC: G05G15/00
Filed: 1949-03-15
Abstract: 672,202. Retractive switches. TELEPHONE MANUFACTURING CO., Ltd., and SIMONS, M. Feb. 27, 1950. [March 15, 1949] No. 7061/49. Class 38 (v). [Also in Group XXIV] A combined coupling and switch, for a magneto-generator in telephone ringing apparatus, comprises a driving shaft 10, on which a handle is mounted at 11, and a driven gear 12. The gear 12 has limited rotational freedom upon the shaft 10, and is integral with a sleeve 13 having slots 13a through which a pin 15 projects. The pin 15 is fixed to the shaft and is engaged by an arm 14 pivotted on the sleeve 13. A collar 16 of moulded insulating material is axially movable on the sleeve 13, and touches an electric contact 19. Springs 17 urge the collar 16 away from the gear 12. On the initial rotation of the handle at 11, the inertia of the magneto-generator causes the shaft 10 and pin 15 to rotate with respect to the gear 12 ; the arm 14 is thereby rotated about its fulcrum so that its end pushes the insulating member 16 to the right against the resistance of the springs 17, thereby altering the state of the electrical contacts 19, 20, 21. When the pin 15 receives the end of the slot 13a, direct drive obtains and the gear 12 rotates with the shaft 10. The Provisional Specification describes a form of the invention in which the axial movement of the member 16 is caused by the radial movements of balls which are partially recessed in the shaft 10. Specification 672,140, [Group XXXV], is referred to.

Title: Improvements in or relating to Hand-Tools
Inventor: SOMERVELL ROLAND WILLIAM GORDO
IPC: A01G3/02
Filed: 1966-02-18
Abstract: 1,163,933. Pruners. WILKINSON SWORD Ltd. 16 Feb., 1967 [18 Feb., 1966], No. 7138/66. Heading B4B. [Also in Division B3] A pruner comprises a body portion 12 to which is secured a fixed blade 10 and to which is pivoted, at 31, a movable blade 11, the body portion having an integral handle 18 and having pivoted thereto, at 32, a movable handle 34, the blade 11 being biased to the closed position by means of a spring 55 and having on the rear face thereof a projection 44 which is engaged by a hooked pawl member 40 when the blade 11 is closed, a further pawl member 46 having a tooth 48 engageable with teeth 50 on a rack-bar 51 pivoted to the blade 11 and having a projection 49 engageable by a cam-like stop 54 on a cranked portion of the rack bar, the pawl members 40, 46 being connected to each other by a flexible wire link 47. The pawl member 40 is integral with a spring-influenced trigger 42, operation of which engages the pawl 41 with the projection 44. The invention is also applicable to secateurs and spanners. Operation.-When the handles 18, 34 are squeezed together, the blade 11 is moved away from the blade 10 to grip an item, e.g. a branch, to be cut. The spring 55 acts through the rack bar 51 to clamp the branch between the blades. Thus, although the handle 34 can now be released, the blades continue to engage the branch to be cut. In this condition, the link 47 operates to retract the pawl 41 from the projection 44 on the blade 11 and force the tooth 48 into engagement with one of the teeth 50 of the rack bar 51. Squeezing of the handles 18, 34 causes the rack bar to be moved forwardly, thus forcing the blade 11 further into the branch to be cut. When the pressure on the handle 34 is relieved, the blade 11 is again maintained in contact with the branch to be cut by the action of the spring 55 on the rack bar. The tooth 48 is disengaged from the rack bar and re-engaged with a succeeding tooth immediately pressure is re-applied. Further pressure on the handles 18, 34 causes the rack bar to inch a further distance and the blade 11 cuts further into the branch to be cut. On completion of the cut, the blades are held in a closed position by the action of the spring 55 on the rack bar but the link 47 again acts to retract the tooth 48 from the rack teeth and engage the pawl 41 with the projection 44. The stop 54 on the rack bar biases the pawl 41 into engagement with the projection 44 through the link 47. The stop 54 engages the projection 49 on the pawl member 46.
