Title: Improvements in or relating to dynamo speed controlling devices
IPC: H02J7/22
Filed: 1943-03-03
Abstract: 575,283. Automatic control systems for dynamos. SELF-CHANGING GEAR CO., Ltd., WILSON, A. G. and MILLER, A. A. March 3, 1943, No. 3507. [Class 38 (iv)] To maintain a suitable speed for a dynamo driven by a variable speed prime mover a variable ratio driving mechanism is included in the drive, as in Specification 562,095 for example, and changes occurring in the electrical circuits and the dynamo due to variation in its speed are caused to introduce a higher speed ratio when the prime mover speed is low. The change may be effected by a solenoid or electrically operated brake, for example of the kind described in Specification 568,409, [Group XXIV], having an operating coil M which is energized by the closing of contacts E of a relay R when, due to a fall in dynamo speed, the current in the field winding F of the dynamo D has been sufficiently increased by the automatic field regulator A. If the two speed ratios are controlled by separate electrical controls back contacts E1 1 on the relay may energize a second solenoid to introduce the lower ratio at higher speeds of the prime mover. In a modification, in which the higher ratio is only made operative when the dynamo speed is low enough to cause opening of the automatic cut-out C, an auxiliary relay coil is connected across the cut-out contacts to assist the coil R. In a further modification, Fig. 3, the relay R controls a second relay, the actuating coil R2 of which is across the cut-out contacts C. This second relay has a retaining coil R3 which is connected through the contacts of both relays and across the battery B. The actuating. coil M may be in shunt or in series with the retaining coil.

Title: Improvements relating to riveting method and means
IPC: B21J15/04
Filed: 1951-02-14
Abstract: 687,900. Riveting. PETERSON INDUSTRI AKTIEBOLAG, L. Feb. 14, 1951 [March 1, 1950], No. 3590/51. Classes 83 (ii) and 83 (iv). [Also in Group XXV] In riveting by means of two part tubular rivets the lower rivet part is flanged and has a pointed end so that it may be forced through the material to be riveted without first punching a hole. A machine for carrying out this method of riveting has means for feeding lower rivet parts with a rounded end to a pointing station prior to transfer to the inserting and closing station. A feed arm 5, Fig. 1 has a pivoted and sliding motion by means of a slot 7 about a pivot 6 and at its operative end is bored to receive a plunger 23 terminating in a pointed pin 24. A pin, not shown, determines the lowest position of the plunger in which the point of the pin is below the surface of the arm. In this position a lower rivet part 8, Fig. 4, is fed by rails 35 to a notch 36 in a plate on a pin 33 slidable and rotatable, under spring control, in an arm 29 mounted on the bed 3. A set-screw 39 in a bell-crank 37 forces the plunger upwards, entering the pin 24 into the rivet and forcing it into a recess 31 in a die 30 to effect pointing. The plunger then returns as far as permitted by a spring-like bolt 23, Fig. 6, and the feed-arm moves forward bringing its end into the U- shaped end of the bed 3 with its top surface a little below that of the bed. A reciprocatory and swinging slide 15 brings down a presser foot 14 to force the material 44 to be riveted over the point of the rivet, causing penetration after which the slide 15 is raised, at the same time swinging the presser foot clear of the riveting plunger 10 that descends carrying the headed upper rivet part held by claws 51 and telescoping it over the pointed end of the lower part. The feed arm 5 has meanwhile been raised to the plane of the bed 3 and the rivet is closed in known manner. All the parts are then returned to their initial position ready for the feeding of another rivet. The shaft 4 carries a series of cams that control the various movements.
