Title: Cutters for boring and like bars
IPC: B23B29/034
Filed: 1922-12-12
Abstract: 205,396. Golby, F. W., (Davis Boring Tool Co.). Dec. 12, 1922. Cutters.-An adjustable cutter for boring-tools has a malleable body 5 joining the cutting-edges 6, the body being provided with one or more undulations 9, flattening whereof effects expansion of the cutting-edges. The malleable body is of cold rolled steel and may have the undulations formed by forging. The cutting- portions 7 are of high speed steel and are permanently secured to the body by such means as welding or by tongues 8. In the latter case the body is pressed round the tongues, or the tongues may be formed on the body and the cutters pressed round them before tempering. The edges of the body are bevelled at 11 to prevent the formation of burrs when hammering to extend the cutter. In a modification, the body is formed of two limbs which join the end portions and have undulations in a plane perpendicular to that shown, the ridges on one side being opposite grooves on the other side. In a further modification, the ridges are opposite each other and holes are formed through the body between them. These holes may also be present in the other forms.

Title: Process for the manufacture of chlorinated ethylketones and chlorinated vinylketones
IPC: C07C45/00
Filed: 1935-12-07
Abstract: Carboxylic acid chlorides and vinyl chloride are reacted in the presence of condensing agents to form chlorinated ethylketones which easily lose hydrogen chloride to give chlorinated vinylketones. Condensing agents of the Friedel-Crafts' type, e.g. aluminium, tin or iron chlorides may be used.  Solvents such as carbon disulphide or tetrachloride or petrol ether may be present. In examples: (1) aluminium chloride is added slowly to benzoyl chloride while cooling and passing in vinyl chloride and the product is decomposed with ice water and hydrochloric acid to separate phenyl-dichlor-ethylketone. This yields phenyl-chlorvinylketone on distillation in vacuo; (2) ferric chloride and vinyl chloride are similarly added to a solution of acetyl chloride in carbon tetrachloride and the ketone obtained distilled to give chlorvinylmethylketone; (3) palm kernel fatty acid chloride is converted into the dichlorethylketone and the chlorvinylketone; (4) isovaleric acid chloride yields isobutyl-b -chlorvinylketone, the reaction temperature preferably being below 10 DEG  C.

Patent GB-1194209-A (GB)
Title: Micromanipulators.
Inventor: AXTELL JOHN
IPC: H05K13/00
Filed: 1967-07-27
Abstract: 1,194,209. Welding by pressure. G. V. PLANER Ltd. 24 Oct., 1968 [27 July, 1967], No. 34569/67. Heading B3R. A micromanipulator for accurate positioning of work comprises a control lever 1 coupled to an output member 6 which is movable only in its own plane, in such a way that a joystick-like pivotal movement of the lever 1 causes a proportionately smaller movement of the output member 6, or alternatively, the lever can be locked relative to the output member 6 whereby a joystick-like movement of the lever causes a corresponding movement of the output member 6. In one embodiment (as shown) the lever is coupled to the output member 6 via two ball-and-socket joints 3, 4 and 8, 10, the socket 8 forming part of the output member 6 and the ball 10 being slidably mounted on the lever and spring-urged into the socket 8. The socket 4 is provided with two coils 12, 13 whereby when coil 12 is energized the socket 4 is secured to the base 14 of the micromanipulator. Thus disposed, joystick-like movement of the lever is pivotal about the centre 5 of ball 3, and a proportionately smaller movement of output member 6 results. Alternatively, with coil 13 energized, the socket 4 is secured to a flange 15 of the output member 6 whereby joystick-like movement of the lever is no longer pivotal, and causes corresponding movement of the output member 6. In other embodiments the ball- and-socket joint 8, 10 may be on the opposite side of the centre 5 of ball 3, whereby the output member 6 moves in a direction opposite to that of the lever 1. The joint 3, 4 may be a universal joint or a diaphragm-type joint. The distance of the centre of ball 10 from the centre of ball 3 may be variable by a screw-mechanism, to vary the proportionality of movement in the instance that pivotal movement of the lever is possible. The means for looking the socket 4 to the base 14 or flange 15 may be mechanical, e.g. with a bayonet-type action, or by means of locking pins, or locking may occur by lifting the lever 1. The output member 6 has a workpiece clamp 17, and the work may be further manipulated either by rotational movement or movement normal to the output member 6, or both. In the former case a shaft clamped in clamp 17 is rotatable from a motor and in the latter case a motor may be coupled to a lead screw coupled to a shaft clamped in clamp 17. The manipulation can be by mechanical drive to the lever 1.

In Fig. 2 infra-red radiation from two fields of view 12, 14 pass through a window 22 of calcium aluminate glass to a ring lens 24. of bloomed arsenic trisulphide, which focuses the radiation on the axis. The lens 24 is a body of revolution of which the outer surface may be hyperbolic or circular in section and the inner surface rectilinear. From the foci of lens 24 incoming radiation is reflected by elliptical mirrors 42, 56 through filters 34, 48, which pass only a particular range of infra-red wavelengths to the sensitive elements 32, 46 of photo-cells. The fields of view are limited by a central stop 60, stops 38 and 52, and by the edges of mirrors 42, 56. If a source of infra-red radiation enters the field 12 there is a change in the output of photo-cell 32 which may be used to set an explosion initiating circuit which is completed by an impulse from photo-cell 46 when the target enters field 14 provided no undue delay has occurred. A delay may be introduced between the impulse from cell 46 and explosion, the delay being determined by factors such as the duration of the pulses, the delay between the passages through the two fields of view, and the estimated relative velocity.
