Title: Improvements relating to typewriters
IPC: B41J19/40
Filed: 1950-11-10
Abstract: 702,747. Typewriters. JARDINE, Ltd., J., and HARDY, F. S. Jan. 17, 1952 [Nov. 10, 1950], No. 27482/50. Class 100 (4) In a space bar mechanism for a typewriter the carnage escapement dog A is operated to release the carriage by a tumbler B on a pivoted lever C striking a tappet or arm A<SP>1</SP> on the dog, the lever normally resting on a stop E and being moved about its pivot C<SP>1</SP> a predetermined distance away from the stop by a slide F moved by the space bar G and automatically returned into engagement with the stop by a spring E<SP>1</SP>, the tumbler then being carried by its momentum into engagement with the tappet on the escapement dog to operate the latter. The tumbler B is pivoted at B<SP>1</SP> to lever C and is normally clear of the tappet A<SP>1</SP> when lever C is in engagement with stop E. A pawl F<SP>1</SP> on slide F engages on abutment C<SP>2</SP> on lever C so that when the slide moves the pivot moves the lever away from stop E until the abutment C<SP>2</SP> rides off the pawl, the pawl being held in its operative position by a spring F2 which permits re-engagement with the abutment C<SP>2</SP> when the slide F moves back and the spring E' returns lever C. When lever C thus re-engages stop E, the momentum of tumbler B causes it to rotate about its pivot B' and strike the tappet A' to operate the escapement dog A, the tumbler being returned to its normal position by the dog A when the latter returns. A spring may be provided to return the dog A, and the tumbler B is preferably so mounted that it reassumes its normal position by the action of gravity. The dog A comprises a pallet H which engages in the teeth to hold the escape wheel J, and a second pallet K which moves into the path of the teeth when the latter are released by the pallet H and is engaged, by the teeth which return the dog to its normal position with pallet H engaging the next tooth. The space bar G is carried by levers L pivoted to the frame at M and connected by a bar N, the latter connecting by bracket O and link P to the slide F. The bar G is returned by springs Q on one or both levers C. Specification 683,208 is referred to.

Abstract: 443,602. Wireless receiving - apparatus ; cathode-ray tubes. FERRANTI, Ltd., CHILCOT, A. L., and TAYLOR, M. K., Hollinwood, Lancashire. Sept. 25, 1934, No. 27548. [Classes 39 (i) and 40 (v)] Visual tuning-indicators for radio receivers comprise an evacuated cathode-ray device containing controlling means receiving varying voltage bias to vary the angle of divergence of either an electron beam or a shadow within such beam, and so to produce corresponding changes in the illuminated area on a fluorescent anode. An elongated, directly or indirectly heated cathode b, Fig. 2, is arranged between an anode c coated with fluorescent material and a semi-cylindrical control electrode d having its axis co-planar with the cathode b. Negative potentials varying with the strength of the signal carrier wave are applied to the electrode d to vary the breadth of the electron beam to the anode c. These potentials are generated across a resistance j in the circuit of a rectifier anode h, the modulation component being applied to the grid o of the triode amplifier through a condenser n. With the electrodes b, d connected directly across the resistance j as shown, the edges of the illuminated area on the anode c are blurred due to the modulation component but this may be avoided by a condenser and resistance circuit allowing only the D.C. component of the voltage across the resistance j to control the beam from the cathode b. In modified constructions of indicator, the electrode d comprises two surfaces shaped to follow the contour of the outer streams of electrons and having a junction line co-planar with the cathode b, or is replaced by a wire between the cathode and anode to cast a variable shadow on the anode. In other modifications, the electron beam passes up into an openfronted or slotted box-like anode coated with fluorescent material on the front of its rear wall, with or without a metal gauze across the bottom, or into an inverted V-shaped anode c, Fig. 5, with a slot r at the front and coated on the front of the back limb with fluorescent material. The indicator may be contained within an envelope only slightly larger than the electrode assembly or within the envelope of the rectifier or other valve of the receiver.

June 21, 1966, No.27587/66. Heading G1Q. [Also in Divisions G4 and G5]  In an electro-chemical cell 1 having indicating electrodes 4 and other electrodes 6, the indicating electrodes are of a valve metal such as niobium or titanium which is surface oxidized. When a current is passed between an electrode 6 and an electrode 4 the oxide coating on the latter changes colour (e.g. from grey to black) and also changes in resistance and electro-chemical potential. These changes are related to the quantity of electricity which passes, so that the cell functions as an integrator. It is also possible, by selective energization of pairs of electrodes 4 and 6, to change the colour of one or more of the electrodes 4 from black to grey or vice versa. This property enables the cell to be used to display controllably changeable black-grey patterns, e.g. Fig.1 (not shown) patterns representing the digits 1 to 9. The non-indicating electrodes 6 may be of graphite or of oxide-coated valve metal like the indicating electrodes.

Title: Improvements in or relating to the dressing of abrasive hobs
IPC: B24B53/08
Filed: 1956-09-10
Abstract: 811,473. Dressing abrasive hobs. REISHAUER-WERKZEUGE A.G. Sept. 10, 1956 [June 11, 1966], No. 27603/56. Class 60. Apparatus for dressing the helical thread of abrasive hobs for grinding gears comprises a carriage on which the dressing device is mounted and which is traversed by a lead screw and nut mechanism driven through change gears, the displacement effected by the lead screw and nut per revolution of the abrasive hob being a multiple of the pitch required on the hob and the said displacement being imparted to the carriage through a lever transmission reducing the movement by the rates of said multiple. The abrasive hob 45 is mounted on the end of a shaft 6 driven through gears 40, 41 by a shaft 5 which also drives, through change gears 50, 62, 63, 64, a lead screw 7 ; the shaft 5 is driven through reversing gearing by a shaft 4 driven by a motor 9. The reversing gearing is operated by a piston 37. The dressing tool 98 has the shape of a turning tool the profile of which corresponds to that of the gap of a toothed rack. Th dressing tool 98 is carried by a compound slide, being secured to a top slide 90 movable on ways 901, 902 on a bottom slide 85 movable on ways 1003, 1004 on the machine frame 1. The top slide 90 is formed with a cylinder containing a piston 99 adjustable by a screw 106 journalled in the bottom slide 85 and operated by a handwheel 107. The bottom slide 85 carries a screw 84 rotatable, through gears 86, 87, by a handwheel 39 and engaging the end of a slidable rod 8. The rod 8 is connected at 76 to a lever 75 pivoted at 74, the lever being connected at 77 to the nut 70 on the lead screw 7. Pressure fluid from a pump 122 is supplied to the cylinder containing the piston 37 for operating the reversing gearing and to the cylinder in the top slide 90 under the control of a reversing valve 120 operated, through levers 115, 117 on a shaft 116, by dogs 111, 112 on the lower side 85. Thus, at the end of the working stroke of the dressing tool, the top slide 90 is moved to withdraw the dressing tool from the hob, and the direction of rotation of the lead screw 7 is reversed. At the end of the return stroke, the opposite takes place. In a modification, the lead screw nut is driven in rotation but is restrained axially, whereas the lead screw is restrained from rotation and therefor moves axially. Two dressing tools may be used, each of which operates on one of the two flanks of the hob. Multi-start hobs may be dressed, either indexing means or a number of tools corresponding to the number of starts being used.
