Abstract: 229,322. M³hlstock, A. Feb. 12, 1924, [Convention date]. Window-shutters; electric window opening and closing apparatus.-Folding shutters are automatically opened and closed at predetermined times by screw and nut gearing 6, 4 operated by an electric motor having an adjustable timeswitch 39 and pole-switches 34, 35 in the circuit. The pole-switches 47 and 49, or 48 and 50, are operated by the closing of the circuits 52, 43, 44, 39, 40 or 41, 34 or 35, 51, by means of the hand 39 of the time switch. The motor is driven in the direction for opening or closing the shutter thereby until a stop 16 on the shutter opens one of the switches 17, 19 in the fully-opened or fully-closed positions. A shunt circuit 38 from the time switch continues to energize the pole switches should the time switch break contacts 40 or 41 before the movement of the shutter was completed. A switch 42, adapted for hand operation, is placed in the circuit, the contacts 45, 46 replacing 40 and 41 respectively.

Abstract: 1,158,305. Welding by pressure. KENTUCKY ELECTRONICS Inc. 26 Jan., 1967 [28 Jan., 1966], No. 4018/67. Heading B3R. [Also in Division H1] In making an electrode structure for an electron tube comprising a curved body member and a mounting member contoured to fit the curved body member embossed projections are provided on one of the members and welds are formed between the members in the regions of the projections. A metal, e.g. stainless steel mounting strap 11, Fig. 1, to be welded to a cup-shaped stainless steel electron tube electrode body 10 has a contoured face to fit the body 10 and this face is formed with embossed projections 20 to be welded by individual portions 13 on an electrode 12. The body 10 is supported on a mandrel 26 on a turn-table 25 and the strap 11 is supported on an insulating collar 27 surrounding the mandrel while upstanding fingers 28, 29 engage the legs of the strap. The electrode is carried by a head 30 for horizontal movement which is connected to one side of a timer and transformer 35 the other side of which is connected to a brush 38 engaging a track 39 on the turn-table. Welding current is passed through the back of the projections by the electrode portions 13 which spanthe embossed zones so that welding of the projections to the body 10 occurs and the strap engages the body in face to face contact. During welding a pool of molten metal is moved outwardly around each projection which is trapped between the unheated interface between the parts to form a reversely directed projection weld around the raised surface. The legs of the strap are to be embedded in thermoplastic material to form part of a colour television electron gun. The projections may be formed on the wall of the body 10 instead of on the strap and ultrasonic welding may be used instead of resistance welding.

As shown, Fig. 1, dies (25), 26, for crimping wire and insulation respectively are associated with an actuator 34 for a blade 28 for shearing a carrier portion 18<SP>1</SP>, Fig. 2A, of the terminal strip. The strip is fed to the crimping dies between a block 46 and a guide 48 with the carrier portion 18<SP>1</SP> in a slot 33 in the blade, the blade shearing the portion 18<SP>1</SP> against the edge of the crimping anvil (24) and the edges of the recess 29 in which the blade is spring-mounted. A conductor wire (not shown) is guided towards a stop 38 along a notch 36 in the blade 28 and a notch 35 in the actuator co-operates with the notch 36 to hold the wire during shearing. An adjustable guide 54 is positioned for engagement by the forward edges of the crimping tabs of the terminals 17<SP>1</SP>. The terminal strip is fed to the crimping dies by a feed finger 66 mounted on a carriage 64 urged towards the dies by a spring 96, Fig. 12, and retracted by engagement of a cam 90 with a follower roller (86), Fig. 8 (not shown), mounted on a shaft 84 projecting laterally from the carriage 64. The finger 66 is urged by a spring 65 to enter a hole in the strip rearwardly of the terminal to be crimped for feeding the strip towards the crimping dies. A drag lever (74), Fig. 10 (not shown), prevents retraction of the strip during the return stroke of the carriage 64. An adjustable stop 98 is positioned to stop the carriage when the hole in which the feed finger is engaged is spaced from the crimping position by the distance between that hole and the terminal to be crimped. There may be a hole aligned with, Fig. 2 (not shown), or adjacent, Fig. 2A, each terminal, the hole in which the feed finger is engaged to feed a terminal to the crimping position being that associated with a terminal to the rear, in the feed direction, of that terminal. The cam 90 is also adjustably mounted to allow the starting point of the feed stroke to be varied.

A transforming arrangement for coupling a high-impedance source, e.g. a 10 megapulse/sec. clock pulse generator 10, to a low impedance bus-bar 24 comprises an input transformer 12 coupling the generator to the series inputs of a pair of coaxial cables 32, 34 which are connected at their output ends to spaced points 20, 22 on bus-bar 24 respectively through transformers 38, 46. The transformer 12 consists of a toroidal core 52 having a high low-frequency (<1000 kc/s.) permeability and a bifilar winding designed to effect an impedance transformation of e.g. 21: 12. Coaxial cable 32 is wound ten times around a toroidal highpermeability core 54 and is connected at its output end to the input of a toroidal transformer 72 having a bifilar winding affording a transformation ratio of 4: 1. The output ends of the winding are connected in common to point 20 on the bus-bar. Output transformer 46, coupled between cable 34 and the bus-bar, is similar to transformer 38. Taking into account the 2: 1 transformation ratio of the coaxial cable pair, the total impedance transformation ratio is about 50.
