Title: Improvements in or relating to machines for the automatic hardening of gear wheels
IPC: C21D9/32
Filed: 1937-05-05
Abstract: 495,374. Hardening gear - wheels. SHORTER PROCESS CO., Ltd. (I. G. Farbenindustrie Akt.-Ges.) May 5, 1937, No. 12841. [Class 72] In a machine for hardening gear-wheels of the type in which the wheel is rotated intermittently to bring each tooth successively in front of a heater which is progressed along the tooth, an electrical contact in the heater carriage operates at the end of each tooth hardening operation to cause electromechanical means to rotate the gear-wheel through the space of one tooth, the said means being rendered inoperative whilst the next tooth is being hardened. The wheel 11 is mounted in a shaft in proximity to a burner 6 mounted in a carriage 3 on which is slidably arranged an arm 4 provided with a driving wheel 7 constrained to remain in contact with a cam 8 by a solenoid and moved over said cam by a motor 10. Contacting with the wheel 11 is a wheel 12 mounted on a shaft which is driven by a worm 14, worm wheel 13, and change speed wheels 15, 16 from a motor 17. The shaft 18 is provided with a contact disc 19 which after each revolution of the shaft operates an electric relay 20, the motor 17 being connected to a contact 21 arranged on the carriage 2. A countercontact 22 is arranged on the carriage 3. When a tooth has been hardened by the burner 6, i.e. when the carriage 3 has reached its final position, the motor 17 is switched on by the connection of the contacts 21, 22 and the wheel 11 moved the space of one tooth. After one revolution of the shaft 18 the disc 19 operates the relay 20 and the current to the motor 17 is switched off. In a modification, the wheel 11 is turned through a train of gearing by means of a ratchet wheel and pawl operable by an electromagnet controlled by a relay operated by the burner carriage. In a second modification, the shaft carrying the wheel 12 is provided with a dividing plate having a plurality of equispaced circumferential apertures adapted to be engaged by a spring-pressed index pin magnetically controlled in such a manner that the pin is withdrawn to allow rotation of the plate when the magnet is energized by a relay. The burner carriage may be returned to its initial position as described in Specification 466,812.

Abstract: 979,650. Space vehicles altitude control. BENDIX CORPORATION. April 1, 1963 [April 2, 1962], No. 12851/63. Heading H4D. [Also in Division G3]  The attitude of a space vehicle is controlled by a sun seeking device comprising a first plurality of light-sensitive elements 9, Figs. 1 and 3, in a common plane, a second plurality of light-sensitive elements 37-44, along the walls of a prismatic surface perpendicular to the plane, and a shade 7 above the whole with a central aperture 10, the arrangement being such that light rays only fall on the elements of the first plurality when the symmetry axis Z of the device is substantially directed towards the sun and upon the elements of the second plurality only when the symmetry axis Z makes a large angle with the direction of the sun, the elements of the two pluralities being further interconnected so as to provide appropriate signals when the symmetry axis of the device makes angles with the direction of the sun intermediate the two above-mentioned extremes. The device shown comprises four upwardly facing coplanar light-sensitive elements 11, 13, 15 and 17, and eight outwardly facing light-sensitive elements 37-44, arranged on the outside of an octagonal mounting 45. The shade 7 is provided with a square aperture 10 aligned with the elements 11, 13, 15 and 17. The mounting 45 comprises a lip portion (see Fig. 1), overlying and shading the elements 37-44 from rays of light within a solid angle of 15 degrees with the Z axis. The whole assembly is enclosed in an evacuated dome 8, coated with a material, e.g. evaporated aluminium, to cut light transmission to 10%. The elements of the two pluralities are connected in parallel in two groups or channels, as shown in Fig. 4, channel A detecting displacement of the sun's rays about the X axis, Fig. 3, and channel B, detecting displacement of the sun's rays about the Y axis. The variation of the output of channel A with the zenith angle 0 of the incident light rays is given in Fig. 7 for two valves of the azimuth angle #. The X axis is taken as defining #=0. The output graph for channel B will be identical with Fig. 7 excepting that the values of # are the complement of those given in Fig. 7. As and when the device revolves around an axis having a constant zenith angle, the output of each channel will vary is shown in Fig. 8 for four zenith angle values. It will be seen that the outputs are 90 degrees out of phase. The outputs from the channels may be used to actuate servo motors to keep the Z axis aligned with the sun, or they may be compared with fixed signals Eb, Fig. 4, and then fed to the servomotors, to keep the Z axis aligned with a chosen direction, relative to the sun.

Title: Composite compressor or like rotor blades
IPC: F01D5/16
Filed: 1968-03-18
Abstract: 1,149,549. Moulding rotor blades. GENERAL MOTORS CORP. 18 March, 1968 [12 July, 1967], No. 12965/68. Heading B5A. [Also in Division F1] A composite compressor or like rotor blade comprises a metal aerofoil member (12) having a stiffening coating layer (26) of filaments bonded together in parallel side by side relationship by a thermosetting resin. The filaments have a modulus of elasticity of at least 40 x 10<SP>6</SP> 1b./in.<SP>2</SP> and may be formed of pure boron deposited on a tungsten wire core, or of graphite or silicon carbide, the bonding agent being epoxy, polyimide or polybenzimadazole resin. The metal member (12) may be titanium or aluminium or alloys thereof, steel, or copper alloys such as brass or bronze. Sheets of the filaments are formed by coating an aluminium cylindrical mandrel with a sheet of polyvinyl chloride film, heating the mandrel to about 95 F., coating the film with resin and then rotating the mandrel so as to wind a continuous filament thereon. The filament passes through a cleaning tank of toluene during the winding operation. The wound filament is then coated with resin and wrapped with a further sheet of polyvinyl chloride film, after which the sheet and filament sandwich is removed from the mandrel by cutting through the sandwich along the length of the mandrel. The sandwich is clamped to a piece of wood and partially cured in an oven for 50 minutes at 165 F., the result being a sheet of parallel, bonded filaments. Sections corresponding to the convex and concave faces of the aerofoil metal member (12) are then cut from the sheet, placed over the cleaned and etched faces of the member and inserted in an aluminium reinforced resin mould. The mould is subjected to a pressure of 200 1b./in.<SP>2</SP> and heated for 1 hour at 200 F. The composite blade is then removed from the mould, coated with resin, replaced in the mould, and cured for 1 hour at 200 F. and a further hour at 300 F. under 200 1b./in.<SP>2</SP> pressure. The blade is removed from the mould and the cure completed at 300 F. in a forced draught oven for 2 hours. The resin used may consist of 100 parts by weight of epoxy resin, 1O1 parts of methyl nadic anhydride and 1À5 parts oftri-dimethylaminomethylphenol catalyst. Several layers of filaments may be bonded to the metal member, the filaments being parallel in each layer but differing in direction to those of other layers.

Abstract: 592,683. Storage cabinets. RIGBY, Ltd., R., and CROSS, H. J. May 24, 1945, No. 12994. [Class 52(i)] [Also in Groups XVII and XXV] In a film-spool storage cabinet having a series of compartments each closed by a separate door or lid, the fastening for which is such that no door, except the first of the series, can be opened unless the preceding door of the series has been fully opened, as described in Specification 519,284, [Group XXV], the fastening is effected by a pivoted member engaging a notch in one wall of a spool - receiving pocket carried by the door and released by cam action of a pocket wall in the preceding compartment. Means are also provided to prevent complete closure of a door if the corresponding compartment contains no spool. Fig. 3 shows in plan three compartments a, b, c, of a cabinet separated by partitions 1, 2 on which are pivotally mounted V-form catches 3, 4 with one limb of the catch on each side of the partition, the transverse connecting portion of the catch passing through an arcuate slot 5. Each door carries two pocket side-walls 7, 8 between which the spool is received, the wall 7 having a cam edge 7<1> clear of the catch when the door is closed, Fig. 2, but engaging and lifting the catch when the door is swung open about its hinge 10 as in Fig. 4, the opening movement of the door being limited by engagement of the catch with a shoulder 11 at the end of each edge 71. The catch fastens the door of the adjacent succeeding compartment of the series by engagement with a notch or shoulder 9 in the upper edge of the pocket wall 8 therein. Complete closure of a door in the absence of a spool is prevented by a member 12 freely movable on a pivot 13 between the walls 7, 8 and so balanced that a foot 15 tends to hang vertically below the pivot 13. If the door of an empty compartment be closed the foot engages the floor of the compartment and supports the door in partly open position. A spool fully inserted in a compartment rests on an arm of member 12 and holds it against a stop 14 with the foot clear of the compartment floor, Fig. 2. When a spool is partly removed or inserted, Fig. 4, counter-clockwise movement of member 12 is limited by the stop. As the door fastening of the first compartment a is not to be controlled, no notch 9 need be provided in wall 8 of the pocket therein.
