Abstract: 994,624. Dry shavers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Feb. 18, 1964 [Feb. 21, 1963], No. 6723/64. Heading B4B. A dry shaver has a shaving head which consists of a reciprocatory movable cutting member arranged within and in co-operative engagement with a tubular fixed cutting member comprising one or more curved, apertured shear plates, the fixed cutting member being supported by the movable cutting member, which is in turn supported from the shaver housing, and the fixed cutting member being held at its ends against reciprocatory movement with the moving cutting member by two abutments on the shaver housing but being movable at right angles to its longitudinal axis relative to the shaver housing. As shown in Fig. 1, a cylindrical cutter 3 is located inside a cylindrical shear plate 2 and is supported at its ends by a frame 4 which is driven to reciprocate in the direction indicated by the arrows P. The frame 4 is urged on to rollers 5 in the shaver housing by means of a roller 6 carried by a spring-loaded pivoted arm 7. Springs 9, 10 draw the shear plate 2 on to the cutter 3. The shear plate is prevented from reciprocating with the cutter by means of abutments 11, 12 formed by the housing 1. The shear plate is provided with two groups of apertures 27, 28 and can be turned about its longitudinal axis relative to the cutter to bring either group into the operative position. In a modification, two flexible shear plates 14, 15, Fig. 4, are joined along the side edges by fillets 16, 17. The diameter of cylindrical cutter 18 is greater than the maximum distance between the inner surfaces of the plates 14, 15 prior to assembly. There may be more than two shear plates. In another modification, the fillet 16 has a longitudinal slot 19, Fig. 6, in which is slidably accommodated a hair-clipping blade 20 formed with a row of teeth 29 and connected to the cutter 18. The teeth 29 co-operate with a row of teeth 21 on the fillet 16. In a further modification, Fig. 7, the blade 20 and the row of teeth 21 are shaped to conform to the curvature of shear plate 14. The fillet 16 is also formed with a row of teeth 22 on its inner side for co-operation with a row of teeth 26 on blade 20. The shear plate is provided with a row of apertures through which the user's hair can enter to be cut by the teeth 22 and 26. The teeth 22, 26 may be used for cutting longer hairs and the teeth 21 and 29 for cutting shorter hairs. The shaver housing includes two screens 24, 25; the screen 24 being detachable or pivotable away from the shaving head to allow the hair clippers to be used and also to allow the shear plate to be adjusted to the desired position.

Abstract: 652,886. Photo-electric control systems. KUTCHUKIAN, N. March 5,1948, No. 6925. [Class 40 (iii)] In a device for scanning an indicating panel 5 on which markers 12 are placed to indicate various data, their position along the panel representing, for example, the time sequence of a series of operations, an assembly 16 which projects a beam of light parallel to the face of the panel is traversed along the panel at a uniform speed. The presence of a marker prevents the light from reaching a photo-cell carried by this assembly and gives a warning or control signal. As shown, a synchronous motor 3 traverses the assembly 16 on insulated wheels 4 on currentcarrying rails 1a, 1b parallel to the face of the panel, one rail being raised above the other to locate the carriage accurately. An assembly 10 depending from the main carriage 16 and steadied by a rail 1c carries a light source 11 which projects a rectangular beam of light parallel to the face of the panel to a photo-cell 14. Interruption of the light by a marker operates an audible or visual signal. A number of light sources and a number of photo-cells sensitive to various wavelengths might be used, the markers being constituted by filters. The markers may also comprise a prism or mirror so that they light up when illuminated. Overhead conductors may be provided to carry the photocell output to remote apparatus.

Title: Improvements in or relating to a machine for rolling screw threads or the like on bolts, cap screws or the like
IPC: B21H3/04
Filed: 1951-04-02
Abstract: 692,168. Rolling screw-threads. PEE-WEE MASCHINENUND APPARATEBAU WERNER PLAGEMANN GES. April 2,1951 [April 3, 1950; April 22, 1950], No. 7565/51. Class 83 (iv). In an apparatus for rolling screw-threads or the like on bolts, cap screws, &c., comprising a pair of rollers rotatable in the same direction which roll the thread on a work-piece positioned on a support arranged between the rollers, the feed and ejection of work-pieces is effected by notches in the rollers, and one of the rollers is provided with an ejector in a recess of the roller, which pushes a finished work-piece into a notch of the other roller. Rolls 1 and 3 have recesses 22, 24 for the reception of blanks 21 and finished work-pieces respectively. Adjacent the recess 22 into which blanks drop from a magazine 20 is a leaf-spring 25 which rides under a cover 27 to retain the blank in the recess. On reaching the point A, the blank drops out of the support 28 and the threads are then rolled between the grooved portions of rollers 1, 3, When the next blank 21 approaches point A the spring 25 ejects the finished work-piece into recess 24 of roll 3, from which it drops into a shoot 31, thence by conveyer belt into a collecting tank. Retaining members 29, 30 support the heads of the blanks. The roll 3 is carried on a slide 4 which is hydraulically loaded by means of a piston 6 to prevent overloading in the event of an oversize blank entering the rolls. The peripheral surface of the rolls rises in the arc α to a height corresponding to full depth of the thread to be rolled, is maintained concentric to the roll axis at this height through the arc # and then drops through the arc γ to such an extent that the work-piece then runs idly between the rolls so that no jerks occur when the work-piece is ejected and replaced by a blank. In a modification, Figs. 8 and 9 (not shown), the peripheries of the rollers are, except for the recesses containing the springs and notches, concentric to the axes, a cam on one roll operating an electro-hydraulic device to open and close the gap between the rolls to allow supply of blanks and removal of work-pieces to be effected. In a further modification, Fig. 10, notches 22, 22<SP>1</SP> and 24, 24<SP>1</SP> are arranged at diametrically opposed portions of the rolls, with associated springs 25, 25<SP>1</SP> on the roll 1. In a further modification, three notches are arranged equidistantly around the periphery of each roll. In other modifications, Figs. 12, 13, 14, a number of rolls 46, 47, or a roll provided with a number of thread-forming sections 60- 64 is arranged on each shaft. In order to avoid jerking, the notches of the rolls or roll sections on each shaft are angularly displaced with respect to one another as indicated at 22, 221 and 221, 228, Fig. 13.
