Title: Improvements in or relating to transformer cores
Inventor: KNIGHT FRED
IPC: H01F27/25
Filed: 1968-01-31
Abstract: 1,209,253. Transformers. ROSS & CATHERALL Ltd. 31 March, 1969 [31 Jan., 1968], No. 4863/68. Heading H1T. The core 1 of a transformer is formed by a winding of strip metal 2, such as grain-orientated silicon iron, the core then being coated on its external surface with a hardenable synthetic plastics material 3 to bond the winding into a rigid structure. Prior to the application of the coating 3, which may be an epoxy resin or glassfibre-reinforced plastics material, the core is annealed to relieve strain hardening produced by the winding and forming processes. The core is bonded externally by the coating, which may be applied in a fluidized bed or by electrostatic spraying, to a uniform thickness. Strain introduced in the core by this bonding is partially relieved when the core is cut into halves 4, 5 to receive the transformer windings. The coating 3 may also serve to insulate the core from e.g. toroidal windings applied directly to the core halves. The faces 6, 7 are ground and lapped to reduce the air gap between them.

Patent GB-1440943-A (GB)
Title: Locking devices
IPC: B60R25/04
Filed: 1973-02-01
Abstract: 1440943 Locks LOWE & FLETCHER Ltd 25 Jan 1974 [1 Feb 1973] 5016/73 Heading E2A In an anti-theft lock of the kind in which outward axial movement of the lock-barrel 16 controls movement of the bolt 15 to its fastening position, this is prevented, until the key 22 is withdrawn, by a roller 39 protruding into the keyway 23 and acting on a follower 40 engaging an abutment 41 on the lock casing. Insertion of the key moves or retains the roller in its displaced position. Fig. 2. Rotation of the key and barrel by 30‹ causes the follower 40 to clear the abutment 41 to permit inward axial movement of the barrel under the influence of cam surfaces (45 and 46, not visible) on the barrel and housing respectively. The axial movement of the barrel is complete at 50‹, at which angle the bolt 15 has been completely withdrawn by a cam 26 driven by the barrel. The inward axial movement of the barrel causes a flange 38 on the barrel to allow similar axial movement of a spring-loaded detent 31 which engages under a ledge 33 on the bolt to hold it up against return springs 34. Axial movement of the barrel allows a spring-loaded pin 47 to engage in a circumferential groove 49 in the barrel to prevent its return movement. Further angular movement of the barrel actuates the contacts of switch 13 (not shown) in the usual sequence. When the barrel is returned by the key to its initial position, a ramp 50 is presented to the pin 47 so that it may be forced up clear of the groove 49 by barrel return spring 44. However, the barrel cannot move back because the follower is held against the abutment 41, as shown in Fig. 3, by the presence of the key in its slot. When the key is withdrawn, Fig. 4, the follower may pass over the abutment. Axial movement of the barrel causes flange 38 to draw back the detent 31, thus allowing descent of the bolt.

Filed: 1918-03-25
Abstract: 115,025. Meyer, A. E. April 17, 1917, [Convention date]. Silk-dressing machines; carding - engines; combing-machines; heckling- machines; openers, &c.- A toothed member or cylinder which can be used in the combing, carding, opening, dressing, &c., of fibrous material is constructed to yield about its axis when it meets with undue resistance due to a tangle &c. in the fibre being operated upon. The device is described as applied to a silk-dressing machine of the Brenier-Neyret type. The tufts 6, Fig. 1, of silk inserted in the clamps 4 on the slowly rotating cylinder 3 are subjected to a preliminary treatment by a series of combing-cylinders 22 mounted on the driven frame 16. The cylinders 22 are mounted in split bearings 26, 28, Fig. 5, held together by an adjustable spring 33, so that, in the event of undue resistance, the spindle of the cylinder will rotate in its bearing. The cylinder may be built up in sections 42, Fig. 3, on a fixed shaft 40. The sections are loose on the shaft and are pressed against friction surfaces 51 carried by collars 48 keyed to slide along the shaft. Springs 53 press the parts together. The sections are pressed against a thrust ball bearing 46, and are secured by a collar 55. Each section has a rounded flange 62 to prevent the entry of lint as far as possible. The yielding of the seetions on the shaft 40 may be governed by spiral springs attached to the sections and to the collars keyed on the shaft. After the preliminary treatment, the tufts are treated by the rigidly mounted cylinders 12, 13. The cylinders 22 are cleaned by the brush 35 which transfers the waste to the cylinder 13 on which it is consolidated by the brush 38. The cylinders 12 and 13 may be arranged as yielding cylinders. The cylinders 22 mav be mounted on endless chains instead of the rotating frame 16.

Abstract: 1,183,273. Assembling heat exchangers. LUMMUS CO. 1 Feb., 1968, No. 5284/68. Heading B3A. Apparatus for passing a load through a hole in a member comprises: support means 12, 14, 15; trolley means 16 mounted reciprocably within the support means; locking means on the trolley means for selectively locking the trolley to the support means; power means 18 mounted on the trolley means for imparting axial movement thereto; and connecting means 30 for imparting relative axial movement between the load and the power means. The load comprises a bundle 24 of heat exchanger tubes 26 which are to be passed through an aperture 23 in the wall 20 of a heat exchanger 11. The trolley has a pair of grooved wheels 35, which run on tracks 36, 37, mounted by pedestals 38, 39 on lower support beams 14, 15. A pair of guide wheels 41 contact upper support beam 12 to assist in guiding the trolley. The beams 12, 14, 15 are provided with keeper pins 48, 49, 50, which are engaged by locking bolts 56 reciprocably mounted on the trolley. In operation, the bundle 24 is advanced by a piston 60 working in an hydraulic cylinder 32 with the trolley locked to the support beams. When the piston 62 reaches the end of its stroke, fluid pressure motors 52 are actuated to withdraw the locking bolts 56. Pressure is then applied to the opposite face of the piston and the trolley is moved towards the heat exchanger since its inertia is less than that of the tube bundle. When the bolts 56 are aligned with the next set of keeper pins, they are engaged therewith and the piston 62 is then actuated to drive the tube bundle further.
