Title: Dynamoelectric machine stator and method of producing same
IPC: H02K1/16
Filed: 1965-05-19
Abstract: 1,060,705. Cores for dynamo-electric machines. GENERAL ELECTRIC CO. May 19, 1965 [June 26, 1964], No. 21290/65. Heading H2A. [Also in Division B3] A method of making the stator, Figs. 1 to 12 (not shown), for a refrigeration electromotor- and-compressor unit comprises clamping laminations (41, Fig. 3) together in the vicinity of mounting holes (62) in the laminations by bolts (61) passing through the holes, introducing unhardened adhesive (71) between the clamped laminations except. in the vicinity (72) of the holes, where it is excluded by the intimate contact produced by the clamping force, and hardening the adhesive while maintaining the clamping force. Any slight depressions or irregularities in the vicinity of the holes may be penetrated by the adhesive. A jig (Fig. 4) is used to locate the laminations while they are clamped to a carrier-plate (81) by which they are immersed in a tank of the adhesive (Fig. 6). Alternatively, the adhesive may be injected or forced between the laminations under pressure. A production line (Fig. 7) connected by a conveyer (93) may include assembling, adhesive dipping and excess-adhesive-removal stations, the latter including air blowers, wipers or brushes. The assembly is then passed through an oven (95), for setting the epoxy or acrylic resin adhesive, and a cooling chamber (97) to a conveyer (98) for transportation to machinery for inserting slot liners (52) and forming the main and auxiliary windings (50, 51) which are insulated from the core by liners (52) and separated by phase insulators (59). After mounting on the motor-casing (24), the unit is dehydrated at 155 C. for six hours. In an alternative process, an additional step of welding the laminations (Fig. 8) is included before application of the adhesive. The laminations are aligned by spring -returned jaws (113) expanded against the laminations by axial movement of a central conical member (122). End pressure is applied through springs (129) by a ram (128), and the laminations are joined by an axially-movable welding head (132) between each pair of fixing holes. After removal from the welding fixture the assembly is annealed and provided with the insulated windings before mounting on a carrier ring (142, Fig. 9) held by spring-clamps (146) in a jig. During positioning over a post (151) interlaminate oxide may be broken by striking the core with a rubber mallet. The assembly of laminations, coils and carrier ring (142) is then immersed in a bath of adhesive (Fig. 10) after which it is placed in a drainage trough (Fig. 11). If desired the end turns of the windings may be masked from the adhesive.

Abstract: 406,657. Knitting. BOOTON, J. H., and BOOTON, H., Ross Works, Wanlip Street, Leicester. July 30, 1932, No. 21532. [Class 74 (ii).] To enable reverse or plain plating to be made at will on a machine with independent needles pointed instruments 12 located in the needle tricks are raised to the position shown in Fig. 4 to hold out the white yarn F. The black yarn G thus gets to the back of the needle hook first and forms the face loop of a reversely plated stitch. If, however, the instruments are raised to the position shown in Fig. 1 just before the corresponding needles draw their loops, the white yarn is prevented from moving forward and correct plain plating is ensured. Each instrument is mounted in a jack 13 the lower butt 15 of which is acted on by a radially movable cam 20. The butts 14 are thus brought within range of a battery of selecting cams 21 which raise selected jacks still further. The cams 21 are slidably mounted in a block 44 and are put in by levers 26 operated by a pattern drum 30 ; a second drum 31 selects the yarn feeders 16 by the action of devices 32-37.

Title: Improvements in aircraft
IPC: B64C3/40
Filed: 1965-05-21
Abstract: 1,100,376. Variable-geometry aircraft; controlling aircraft. J. E. CHACKSFIELD. 3 Aug., 1966 [21 May, 1965], No. 21640/65. Headings B7G and B7W. An aircraft includes a pair of wings 5 that are pivotally attached to the fuselage 1 at points H between a foreplane 2 and a tailplane 3 such that when the wings are retracted into a sweptback attitude they abut the tailplane to form a lifting surface of substantially delta-shape, Fig. 1, whereas when the wings are moved into a fully-spread attitude they form with the foreplane associated lifting-surfaces, Fig. 2, for lowspeed flight. The foreplane may be situated at a higher level than the wings so that its trailing edges lie abaft the leading edges of the wings when the wings are fully-spread thereby defining with the upper surface of each wing a slot (Y), Fig. 3 (not shown), which is said to improve the flow of air across said surface. Alternatively, the wings abut the trailing edges of the foreplane when they are fully-spread, the wings being pivotally attached to portions (11), Figs. 6 and 7 (not shown), of the foreplane at the roots thereof adjacent the fuselage. In this arrangement, pitch-control surfaces 6 on the foreplane are split and contrived to embrace the leading-edges of the wings when the wings are fully-spaced, Figs. 8 and 9 (not shown), so as to form a continuous lifting surface. Flaps and ailerons 7, 8 on the wings may also be split and contrived to embrace the leading-edges of the tailplane when the wings are retracted. A linkage-system containing a toggle-mechanism that is actuated by an hydraulic ram (14), Figs. 11 and 12 (not shown), may be lodged within each of the split control-surfaces to effect displacement of the upper and lower portions thereof relative to each other when the attitude of the wings is changed, the said system being combined with a torque tube (12) and hydraulic actuator (15) for pivotal movement of the control surface about the axis of the tube. The pivots for the wings may have limited freedom to move in a fore-and-aft direction, Figs. 4 and 5 (not shown), when the attitude of the wings is being changed.

Abstract: 473,719. Electric clocks. ALLGEMEINE ELEKTRICITATS-GES. Aug. 7, 1936, No. 21862. Convention date, Aug. 7, 1935. [Class 139] An escapement 2 including a balance wheel 1 and hairspring 3 is controlled by a device which impresses oscillations of definite frequency on the wheel 1 by way of the spring 3, the device being continuously and mechanically connected to the spring so that the latter is moved sinusoidally with respect to time in its natural direction of movement and the escapement being capable of operating when the controlling device is out of action. Curb pins embracing the hairspring are carried on an arm 4 which is mounted on a spindle 9 together with an arm 7 having a part 5 secured to the free end of the hairspring. Arm 7 is oscillated by crank 6 and gears 8, 8<1> from a synchronous motor. The balance is thus forced to oscillate synchronously with the driving motor. Arm 4 may be adjustable relatively to arm 7 ; for this, the arm 4 may be free on spindle 9 and coupled frictionally to arm 7. A small spring may be attached to arm 7 so that if the motor stops, the arm 7 is brought into a predetermined position so that arm 4 comes to rest in a suitable position.
