Title: Improvements in photo-electric engraving
IPC: B41C1/04
Filed: 1951-01-19
Abstract: 687,613. Engraving. HOWEY, W. C., and HOWEY, W. R. Jan. 19, 1951, No. 1528/51. Class 100 (ii). [Also in Group XL (b)] In a process of engraving a sheet of material for copying an original design by means of photo-electric scanning in which an oscillating engraving tool is used having its depth of cut controlled by the photo-electric cell, the tool (Fig. 3) has a shank formed towards the end with a square portion 15 tapered at a uniform angle towards a point 14 formed with a larger angle of taper. As shown, the point 14 is conical. In an alternative embodiment, Fig. 4 (not shown), the point is pyramidal. The tip 24 may be slightly rounded. Fig. 6 shows the impressions formed with a tool having a conical point. The impressions formed are wholly conical for shallow cuts and become square in cross section merging into conical shape for deep cuts 22. The upstanding portions between deep cuts have a steep pillar-like structure and are not easily crushed when a matrix is taken from the sheet under pressure. For engraving celluloid, the tool is heated electrically by a coil surrounding the shank and is clad with a layer of copper so that heat is readily conveyed to the point. Typical dimensions for the tools are given.

Abstract: 664,422. Chain-shift gear. RUMBLE, A. J., RUMBLE, A. J., and STUPPLE, R. A. Jan. 13, 1950 [Jan. 20, 1949; Jan. 28, 1949], Nos. 1604/49 and 2393/49. Classes 80 (i) and 80 (ii). A spring-loaded post 2 carrying a chain-tensioning sprocket 1, or pulley in a cycle variable gear of the chain-shift type has spring-controlled rectilinear sliding movement in or on a fixed sleeve 4, to which it is locked in operative positions by a spring-loaded pivoted or sliding multitoothed retractable detent 6, Fig. 1, on either member 4 or 2, engaging rack-teeth 5 on the other member 2 or 4; or by balls 14, Fig. 5, jamming between the post 2 and a coned sleeve 15 on the fixed sleeve 4. During a chain-shift the detent 6 is retracted by a Bowden cable 8 to permit the tension-sprocket to find a new position under its spring-load 3, where it is subsequently locked by release of the cable 8. In Fig. 5, release is effected by depressing a spring- pressed outer sleeve 16, carrying an end-plug 17 which holds the balls 14 jammed in the cone 15, until its release permits the balls 14 to be released by a spring 18 or positively. The release cable 8 may be operated by a common lever controlling the chain-shift fork, as in Specification 598,430, and the gear is suitable for fixed wheel or free-wheel cycles, the latter with or without back-pedal brakes.

Title: Improvements relating to gear mechanism for power drives
IPC: F16H1/28
Filed: 1945-01-23
Abstract: 612,709. Differential gear; securing gears on shafts. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., and McLEOD, R. C. Jan. 23, 1945, No. 1854. [Class 80 (ii)] [Also in Groups XXVI and XXXIII] In a gas turbine plant of the kind having a bladed propulsion means in the nature of a propeller or fan driven from the compressor end of the shaft connecting the turbine and compressor or compressors, the propeller or fan is driven through a reverted reduction gear train consisting of a central or sun pinion 20, intermediate or planet gears 21 and an internally-toothed annulus 22 arranged within an inner wall 12 of a forward facing annular inlet duct to the compressor, the central or sun pinion 20 being connected through a flexible coupling 37 to the compressor shaft and either the intermediate gears 21 or the toothed annulus 22 being coupled directly with the fan driving shaft which is coaxial with that of the compressor. If the gear is used to drive a contrarotating propeller, the intermediate gears and the toothed annulus would be connected to the separate elements of the propeller. The planet gears 21, which may be arranged slightly asymmetrically around the pinion 20 to desynchronize tooth engagement, are mounted on spindle 24 carried by annular side plates 25, 26 which are flanged at 25a, 26a for stiffness. The plate 26 is skirted axially rearwardly at 27 and formed with splines 28 which engage splines 29 formed on a support 30 attached to the fixed casing 12. The second plate 25 is attached at its inner edge to the end of a shaft 8 which forms a support for the bearings of the rotating shaft 7. The shaft 7 is driven from the outer annulus 22 through the dished member 34. The flexible coupling 37 comprises two resilient spaced discs which are attached to each other at the periphery. A tension element 39 attached to the bush 38 and the shaft 6 prevents axial movement between the two parts. Since the internal diameter of the skirt 27 is greater than that of the pinion 20, the gear unit may be easily withdrawn, leaving the pinion 20 attached to the shaft. When the gear is used to drive a contra-rotating propeller, the shafts 7, 8 both rotate and the splines 28, 29 are replaced by a roller bearing..

Title: Improvements in or connected with apparatus for operating watertight and like doors, particularly bulkhead doors for ships
IPC: B63B19/00
Filed: 1923-01-27
Abstract: 215,060. Cleghorn, W. G. Jan. 27, 1923. Operating and controlling doors electrically and hydraulically and by toothed-gear mechanism. -Doors such as bulkhead doors are operated by a compressed air motor of the reciprocating-piston crank - shaft type, the transmission gear between the door and the motor r comprising a pinion or pinions gearing with a rack or racks on the door. The compressed air is supplied from a reservoir located at the door or at a distance, such as in the engine room. The controlling device is arranged to establish a neutral position with the motor inactive, or either of two active conditions for the opening or closing movement, the change to the neutral condition being effected by movement of the door and to the active conditions by hand control. In the arrangement shown in Fig. 1, the vertically movable door B is operated by a motor C through gearing 2 - - 5. An auxiliary driving-shaft D is provided, the clutch of which is rendered inoperative when compressed air is supplied to the motor. The controlling gear to start the motor E is operated by a lever F, movable by a hand-lever H or by a control G operable from a distance. The motor is stopped by lower and upper tappets K<2>, N<2> and K<3>, N<3> respectively on the door as the door approaches its closed or open position. The control gear is shown in section in Fig. 5, the pipe 9 leading to the motor and the pipe 8 to the compressed air supply. The shaft 12 carries an arm K and a disc valve J having two airsupply ports (not shown) and an exhaust cavity 11. The members J, 12, K turn to assume either of three positions : one in which the supply of air is cut off by the valve, and a second or a third position in which the valve is set to supply air to open or close the door respectively. In the neutral position, the air supply is cut off by the valve L. The arms K, N are under the control of a helical spring M. These arms are in the position shown in Fig. 7, with the door in the raised and opened position. To close the door, the starting lever F is turned to move the lever P and allow the arm K to be turned by the spring M for setting the valve for the closing operation. As the door approaches its closed position, a tappet K<3>, Fig. 9, engages one side of the projection K<1> to hold the arm K while the tappet N<3> engages the projection N<1> and turns the lever N to tension the spring M. The valve J is thus returned to its neutral position as soon as the door is suffciently closed for the members K<1>, K<3> to be clear of one another. Tappets K<2>, N<2> on the lower part of the door act similarly to cut off air supply to the motor when the door approaches its fully opened position. Specification 14020/93, [Class 113, Ships &c., Div. I.], is referred to.
