Abstract: 984,791. Dry shavers. NEEDLE INDUSTRIES Ltd. June 30, 1961 [June 30, 1960], No. 22860/60. Heading B4B. In a dry shaver comprising an apertured guard plate 10 and a motor-driven cutter member 14 which includes at least one cutting blade 16 in the form of a concave shell or ring having a curved cutting edge 29 defined by the meeting at an acute angle of the outer face 28 of the shell and a contact face 27, the blade being biased by a spring 25 to urge the contact face against the inner face 13 of the guard plate and being moved along a predetermined orbital path when the cutter member is driven, the guard plate and the blade are thin-walled so that, due to low inertia, the blade can follow deflections of the guard plate resulting from contact with the skin and the blade, mounted on a carrier forming part of the cutter member by fastening means which prevent separation of the blade and carrier but allow the blade to rotate and rock relatively to the carrier, remains in contact with the inner face of the guard member during deflection thereof. The guard plate is of plain carbon or alloy steel and has apertures 37 which diverge towards the outer face 11 so that skin protrudes thereinto, the walls 38 of the apertures being frusto-conical, concave or convex. The cutter member comprises a carrier 15 detachably mounted on a drive spindle 17 and having high carbon or alloy steel cutting blades, of thickness of between 0À003 and 0À005 inch, each secured thereon by a hollow spigot 30 formed integral with the carrier and through which passes a shank having heads 33, 34 which are spaced to allow rocking and floating of the blades. The blades are pressed from sheet steel and have a narrow face 28a making a steeper angle with the plane of the guard plate than the outer surface 28. The contact surface 27 is preferably lapped on a spherical abrasive surface to form a sharp cutting edge 29. Apertures 36 are provided for the escape of cut hair. In use, the blades rotate on their axes due to friction to provide constant lapping and in modifications with no apertures 36 cut hair escapes between the trailing edge of the blade and the guard plate. In further modifications, the generatrix of the blade is curved and the outline elliptical or fluted, the inner and outer walls of the blade are not parallel, the centre of gravity is offset from the axis 26, and the blades move in different orbits, or the trailing edge of the blade is formed by a stabilizing pad. According to the Provisional Specification, the carrier member is retained on the drive spindle by an elastic, synthetic resin plug having a shank entering a bore in the spindle, the spindle has a cut-away portion forming a part of non- circular section in driving engagement with the carrier and of greater axial length than the thickness of the carrier, and the carrier is in the form of a spider carrying more than two blades and has apertures in which the apices of the blades seat. Specification 984,793 is referred to.

Abstract: 669,271. Automatic control of induction heating oscillators; transformers. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 19, 1950 [Sept. 27, 1949], No. 22974/50. Classes 38 (ii) and 38 (iv). [Also in Group XL (c)] In an induction heating oscillator servomotors automatically adjust the tickler coil and load coil couplings to maintain a constant ratio of grid to anode current and optimum load impedance. The construction of the oilimmersed coils is described. Automatic control, Fig. 3.-In a conventional oscillator circuit, Fig. 3, the coupling between the grid coil 7 and the anode coil 2 is adjustable by a servomotor 20, and the coupling between the anode and load coil 5 is adjustable by a servomotor 22. Resistors 37, 38 in the grid/ cathode and HT/cathode circuits provide control voltages proportional to the grid and anode currents, and tapping 39 is adjusted so that Va, Vb is zero at the required condition. This signal may be applied to conventional servo amplifier or to " forward " and " reverse " motor control relays through sense discriminating half-wave rectifiers, Fig. 4 (not shown), to control the oscillator coupling motor 20. The load coupling motor 22 is similarly controlled by a system responsive to the difference between Va and a potential representing the H.T. supply. Where the supply 30 is variable, as by a grid-controlled rectifier, the representative voltage may be obtained from a potentiometer gauged to the rectifier grid-control and energized from an auxiliary D.C. source. Alternatively to produce a power output, i.e. heating cycle, which varies according to a predetermined law, a clock-driven cam may be arranged to control the signal input potentiometer, Fig. 5 (not shown). Coil construction, Fig. 1.-The coils are oilimmersed in a tank 1 with a water cooling pipe 12 at the top. The anode coil 2 is surrounded by a layer of insulation 6 and the load coil 5 which has lead-out connectors 13, 14 mounted on an insulating panel 15 in the side of the tank. The anode coil may be moved vertically with respect to the coupling coil by the servomotor which is mounted on the lid of the tank, Fig. 2 (not shown), and the grid coil 7 may be moved vertically or rotated to adjust the coupling. The anode tuning capacitor elements 3 are also mounted in the tank.

The conveyer 20 comprises carriers 26 slidably supported on pairs of rods extending between corresponding links of driven endless chains 21, 22. Also slidably mounted on the pairs of rods 25 are members 27, 28 provided with downwardly projecting pegs which engage guides (60, 61), Fig. 7 (not shown), causing the members to follow the paths shown in Fig. 1. When an article is classified outside the predetermined range of values, a cam (42), Fig. 9 (not shown), is moved by a ram (40) into the path of a cam follower on one of the members 27, 28 causing this member to be coupled to the corresponding carrier 26 by means of a spring (48) on the carrier, Figs. 3, 5 (not shown). The carrier is thereby diverted to discharge its load at one side of the centre portion of the conveyer. On the return run of the conveyer, the members 27, 28 and carriers 26 are separated and centred.
