Title: Improvements in or relating to sparking-plugs
IPC: H01T13/54
Filed: 1927-07-25
Abstract: 299,412. Guinness, K.. E. L. July 25, 1927. Divided on 284,391. Sparking-plugs.-The central conductor 16 may be replaced by another having the part 30 of a different size whereby the volume of the chamber at the inner end of the plug may be altered. A steel bush 12 encloses the conductor 16 and is insulated from the casing by mica wrapping and washers. Lateral pressure is applied to the casing to effect a permanent union of the casing, mica wrapping and steel bush. At its outer end the bush has a hexagonal flange 13 which is gripped when the conductor 16 is to be removed thus avoiding stress on the insulation during this operation. Betwen the hexagonal portions 19, 13 on the conductor and bush respectively, the former may be reduced in diameter. The application of excessive force will thus result in the fracturing of the conductor before damage can be done to the insulation. The outer part of the conductor may be separate from the inner, the two being connected by a screwed extension and socket as shown in Fig. 1. The threaded extension on the main portion may however enter a plain hole in the outer portion in which case the latter is formed with a threaded recess at its outer end. When the part 16 has to be removed, the outer part 26 is reversed and the threaded members brought into positive engagement. Specification 284,391 is referred to.

Abstract: 299,727. Klinger, J. R. Oct. 27, 1927, [Convention date]. Lubricating.-The skin friction or resistance to propulsion of ships is reduced by providing in front of the bow tubular or hollow plate like bodies to which compressed air or gas is supplied from the ship and from which it is blown out through small openings so that the water which comes into contact with the hull is permeated with air. or gas. In one form, the tube c, Fig. 1, through which the gas is supplied terminates in a number of U- or V-shaped members the arms a of which may be vertical or raked backwards or forwards. Arrangements are also made whereby the pressure of the gases delivered varies with the depth of immersion of the nozzle from which it emerges. Various crosssections of pipes are described as well as internal arrangements of diaphragms which allow the desired variations of pressure. Where hollow plates are employed, the tubes u, Fig. 21, for the compressed air may be carried through the connecting member s. The horizontal plate j which terminates in a pointed end furnished with nozzles h may be associated with spaced vertical hollow side plates the forward edges of which are likewise pointed.

Filed: 1948-12-13
Abstract: 657,573. Seaming non-metallic sheet material. SINGER MANUFACTURING CO. Dec. 13, 1948, No. 32133. Convention date, Sept. 2. [Class 42 (i)] [Also in Group XI] In an electronic seaming machine comprising a reciprocatory electrode intermittently engaging work advanced by feeding- means including a work-contacting presser, and an oscillator for establishing a radiofrequency field in the region of the work engaged by the electrode, there are provided means, actuated by movement of the presser responsively to the work thickness, for limiting electrode penetration into the work and switch means for turning on the oscillator only during engagement of the electrode with the work and for a duration determined by the work thickness. The machine shown is of the type described in Specification 603,412, having, a reciprocatory upper electrode 3 or in which the work material is advanced between successive welds between a presser wheel 81 and a feed wheel 13 intermittently driven from driving shaft 6. An eccentric pin 27 on shaft 6 acts through a strap 42, pivoted at 41 and embracing a hub 39 on a crosshead 37 fixed to the top of electrode bar 34, to reciprocate the electrode 35. Presser wheel 81 is carried on a presser bar 46 slidable vertically in the machine frame and carrying a cam finger 48 which positions a stop arm 71 adjustably pivoted at 72. Downward movement of electrode 35 is limited by engagement of a pin 76 on crosshead 37 with stop arm 71 ; penetration of the material is thus controlled according to the thickness of material, the ratio of electrode displacement to presser bar displacement due to thickness change being determined by selection of the proper pivot point for arm 71 by adjusting pivot 72 in a slot 73. Attached to finger 48 by screws 50 is a switch casing 51 an extension 61 of which carries a lower switch contact 64; the upper contact 55 is resiliently carried by a member 52 spring-pressed upwards in casing 51 against a finger 40 on crosshead 37. Contacts 55, 64 operate to switch the oscillator on and off and are adjusted to close just after electrode 35 engages the surface of the material in descending and to open just before it reaches the surface level of the material on rising again. The duration of the radio frequency field at each weld thus varies, together with the time of engagement of the electrode with the material, in accordance with variations in the material thickness. Specification 649,690 is referred to.
