Abstract: 639,061. Rolling screw-threads. BEDKER, L. W. Aug. 29, 1947, No. 23992 Convention date, Sept. 3, 1946. [Class 83 (iv)] A thread-rolling device comprises means for rotating a work - piece, a thread roll having helical threads formed thereon of opposite hand to the threads to be rolled and of approximately equal helix angle, a support for said roll arranged to present said roll to the work-piece with its axis inclined to the axis of the work-piece in a direction to cause the portions of the threads thereof engaging the work-piece to extend more nearly parallel to a plane perpendicular to the axis of the workpiece than would be the case if the axes of the work-piece and roll were parallel, and means for relatively feeding said roll to depth in said work-piece. The angle' of inclination is less than, and preferably one half of, the helix angle of the rolled thread. Rolls 10, one of which is mounted for adjustment by bolts 15, 16, are connected by gears 17-21 so that they are driven in synchronism by the rotating workpiece 22. In examples quoted, thread rolls having three start threads are used. More than two thread rolls may be used.

Abstract: 182,076. Eikar Ges. Maschinen-und Werkzeugfabrik. June 18, 1921, [Convention date.]. Turning wood-screws.-In a machine for turning woodscrews by means of a rotary chasing cutter of the type in which screws of different lengths and pitches may be cut without changing the gear ratio between the cutter spindle and the work spindle, the transmission gear between the work and cutter spindles is housed within a single bearing assembly of the machine. The blank 1 is carried in a chuck 3a on a spindle 3 mounted in bearings 32, 33 and driven from a pulley 34. The chasing cutter 2 is driven from the the work spindle through a train of gears 5-10 shaft 11 and bevelgearing 12 while further gearing from a wheel 8<a> drives a change-wheel 24 on a control shaft 15<a>, all these gears with the exception of the changewheel remaining unaltered for all types of screw. The reciprocation of the cutter is effected through a hollow shaft 14 having a collar 14<a> arranged in a non-rotary head 30 and traversed axially by an interchangeable cam 31 screwed in bush 28 having external teeth driven through gearing from the control shaft 15a. The stroke of the cam 31 determines the length of the thread and different pitches are cut by adjusting the speed of the control shaft through the change-wheel 24. The chuck 3<a> is operated from the control shaft by means of a cam on a disc 15 which actuates an arm on a spring-controlled rod connected to the chuck operating device 35. Formulae for calculating the speeds of the work and cutter spindles, the diameter of the cutter and the stroke of the cam 31 are given in the Specification.

Class 98(2) The layers contain a water-insoluble resin-like ester of a sulphonic acid of a quinone-(1:2)-diazide with a resin containing phenolic hydroxy groups and if desired an alkali soluble resin or dye and lie on a support as of glass, metal or lithographic stone. On exposure to a light image and development by a dilute alkaline solution with subsequent rinsing with water areas struck by light are removed and the remaining areas accept greasy ink, so that, with a support having a hydrophilic surface, the material can be used in a planographic printing apparatus. The developed material may, however, be heated to obtain a more strongly coloured image or, with a suitable support, may be etched. In Example 1 the condensation product of naphthoquinone-(1:2)-diazide-(2)-5-sulphochloride and o-cresol-formaldehyde resin, prepared by heating these materials in dioxane and precipitating the produce with alkaline water, in solution in a mixture of alcohol and methyl ethyl ketone is applied to a superficially oxidized aluminium foil and dried, the layer produced is exposed under a positive developed with trisodium phosphate solution and acidified, and is then ready for use in a printing machine. In Example 2 a similar solution but including a proportion of shellac is applied to a zinc plate which is exposed, developed, and etched with nitric acid to produce a stereotype. Examples 3 and 4 are directed to grained aluminium foil lithographic plates using 5-methylbenzoquinone - (1: 2) - diazide-(2)-4-sulphoehloride-orthocresol formaldehyde and benzoquinone - (1:2) - diazide-(2)-4-sulphochloride-phenol formaldehyde condensation products respectively; and Example 5 to an anodically oxidized aluminium foil with the 5:6:7:8- tetrahydronaphthaquinone-(1 : 2)-diazide- (2)-4-sulphochloride-orthocresol formaldehyde condensation product.

Title: Improvements in ignition means for internal combustion engines
IPC: F02B9/06

Abstract: 361,408. Ignition devices. SCHURHOFF, A., 29, Gutzkowstrasse, Dresden, Germany. Aug. 20, 1930, No. 24931. [Class 7 (iv).] Ignition is effected at starting by sparking across a gap between electrodes f, carried by a valve e, and the base of a chamber b when the valve is lifted by the compression pressure ; thereafter the valve e, which is a freely-moving member controlled only by the pressure differential existing on its opposite faces, entraps a portion of the combustion gases in chamber b during the working stroke, the heat of these gases effecting the ignition of the charge towards the end of the succeeding compression stroke when the pressure beneath the valve is sufficient to lift it and admit some of the charge to the chamber b. The electrodes f are so arranged as to guide the valve e, the seating of which is grooved to allow a reduction of pressure in the chamber b to take place during the expansion stroke so that the entrapped pressure does not exceed the compression pressure. The lift of the valve may be varied by longitudinal adjustment of the insulated member h by which means the ease of access of the fresh charge to chamber b and hence the time of ignition may be varied. Modified constructions are described in which the valve e is provided with two seating surfaces of different diameter or, alternatively, it may contain a pilot valve which functions in the same manner as the main valve. The seating surfaces may be adjustable.

Abstract: 615,948. Thermal switches. McGOWAN, E., and BRITISH THERMOSTAT CO., Ltd. Aug. 21, 1946, No. 24936. [Classes 38 (iii) and 38 (v)] In a thermal switch two pairs of contacts are operated in succession by deflection of a heated wire element at preselected temperatures of the element. When a wire 9 is heated, by current passing through it or indirectly, it is deflected by a spring 21 acting on a rod 16 which is guided at 17 to move vertically. The rod 16 has an annular groove 16a to which is pivoted the centre limbs of trifurcated blades 23, 23a carrying contacts 24, 24a and fixed by the outer limbs at 36, 36a. By adjustment of contact stops 27, 28, the blades 23, 23a can be arranged to operate at different temperatures of the wire 9. One end of the wire 9 is soldered to a threaded rod 10, and the other end to a nipple 12 mounted eccentrically in an insulator 13. The rod 10 and insulator 13 are rotatably mounted in a rigid frame 6 of a metal having a thermal coefficient of expansion no greater than that of the wire 9. The base 1 is provided with knock-out cable entries 2. The switch may be used to control a refrigerator motor A, Fig. 6, having starting and running windings 38, 37 controlled respectively by the blades 23, 23a, and both controlled by a thermostat C. When the contacts of the thermostat C close, windings 38, 37 are both energized until after a time lag, the contacts 24, 25 open to de-energize the winding 38. The winding 37 is de-energized on overload by the opening of contacts 24a, 25a.
