Patent GB-2004919-A (GB)
Title: Methods of producing surfaces hardened by remelting hardening
IPC: C21D1/09
Filed: 1978-09-14
Abstract: Surface hardening of a cast iron component involving localised remelting is carried out under a protective gas shield by localised heating along melting tracks. Adjustment of the quantity of oxygen accumulated at the surface being hardened yields a desired surface density of the porosity of that surface, and the extent of overlapping of the melting tracks results in a desired pore fineness. Oil emulsion applied upon machining prevents oxygen absorption leading to low surface porosity. Conversely heating in the presence of air or oxygen leads to oxygen absorption and hence high surface porosity. <IMAGE>

Title: Forming halftone images
IPC: H04N1/41
Filed: 1979-07-13
Abstract: A system for forming halftone images from an original comprises a read sub-assembly and a record sub- assembly. The read sub-assembly includes c.r.t. scanner 22 and circuit 54, 56 and 58 to generate and store digital tonal density values of, for example, four adjacent points DN, DE, DS, DW in each discrete picture cell in an original 16. Comparison unit 60 generates a 'high detail flag' signal if there is a large difference or ratio between the density values in one cell and if so all the (four) density values are written in memory 68 for transmission to the record sub- assembly. If there is not a large difference or ratio, a single weighted (average) density value is computed and stored. The stored values are transmitted to the record sub-assembly which selects a dot of the required size and shape from a memory in accordance with the single density value or with the average of the (four) values and generates a visible image thereof on a CRT. If the flag signal is present a comparator logic unit generates shift signals in accordance with the difference in tonal density across the cell horizontally or vertically in order to displace the dot accordingly within the cell. The store 68 may be omitted. <IMAGE>

Patent GB-2035438-A (GB)
Title: Piston pin securing means
IPC: F16J1/18
Filed: 1979-10-04
Abstract: A securing spring is described which enables a piston pin to be secured in a piston in a comparatively easy manner but is less susceptible to breakage, in use, than securing means previously-employed for this purpose. The spring is generally U-shaped with an enlarged head, the arms being stressed to spring apart and being bent outwardly at the ends. The spring is used to secure a piston pin which is in the form of a hollow cylinder and is inserted into the bore of the pin by pressing together the spring arms. When the securing spring is in position, the outwardly- bent ends and the head extend from the piston pin bore and cooperate with the piston to secure the piston pin against axial displacement. The spring arms may be crossed at least once. <IMAGE>

Title: Electrical coupling devices
IPC: H01R13/58
Filed: 1979-12-18
Abstract: In an electrical coupling device, for example a 3-pin plug, of the kind comprising a housing 2, conductor-piercing members within the housing for effecting electrical connection to one or more conductors of an electrical cable 1 and a cable grip for clamping the cable relative to the housing, the cable grip comprises a pair of cooperating jaws 8, 9 which are forced towards one another with the cable 1 therebetween by camming means formed in the housing. The camming means is provided by the opposed walls 18, 19 of a recess 7 in the base 2, which walls force the jaws towards one another to grip the cable when the jaws are pressed into the recess in a direction substantially perpendicular to the path of the cable through the jaws. Movement of the jaws in the direction of the path of the cable through the jaws is limited e.g. by the end wall of the recess, when a tensile force is applied to the gripped cable in a direction tending to pull the cable out of the coupling device. <IMAGE>
Patent GB-799844-A (GB)
Abstract: 799,844. Engine turning gear. KLOCKNER-HUMBOLDT-DEUT AKT.-GES. Jan. 18, 1957 [Jan. 21,1956], No. 1956/57. Class 7(5) In a spring starter in which one end of the spring 1<SP>1</SP>, 1<SP>11</SP> is secured to a stationary part 3 whereas the other end is connected to a rotatable part 5 which can be moved by a winding up device 37, 26, 27 and which by means of a pawl 31 can be coupled to and uncoupled from a serration in a disc e.g. the flywheel 12 connected to the crank shaft of the engine, the movements of thespring when the latter is being tensioned and untensioned initiate the move ments of the pawl for coupling and uncoupling respectively the pawl bearing either directly or with the interposition of an intermediate member against a turn of the spring and being set in motion by movement of the spring. The invention is not limited to use of a spiral spring but can be employed with coil, draw or compression springs. In the arrangement shown, when the spring is wound up the turns of the spring move towards the axis of the crankshaft. The outer turn against .which a two armed lever 33 bears provides room for movement thereof and the lever moves under the influence of a spring 36 in such a direction that the pawl 31 is moved outwardly so that the latter engages the serrations 16 in the flywheel 12. (Fig. 2). The strength of the spring 36 can be so calculated that the pawl 31 engages a serration 16 at a predetermined degree of tension of the spring 1 so that the crankshaft of the engine is turned during the last part of the winding up movement of the spiral spring. The lever 33 locks the pawl in position. -When the spring is released the crankshaft is turned and the lever 33 moves inwardly. When the engine has started and the spring is substantially fully unwound the increasing speed of the flywheel 12 becomes greater than that of the segment 5 and the pawl 31 springs out of engagement with the serration 16. The invention is not limited to interposition of a two-armed lever between the spiral spring and the pawl and it is also possible for one of the turns of the spiral spring when the latter is untensioned to bear directly on the pawl. Nor is it absolutely necessary for the outer turn of a spiral spring to bear against a two armed lever on the pawl. Other turns could be employed for this purpose also.
