Abstract: 1,134,696. Bearings. BELLISS & MORCOM MFG. Ltd. 21 March, 1966 [22 April, 1965], No. 16931/65. Heading F2A. In a bearing cooling system for an air compressor having a high-pressure cylinder 10 and a low-pressure cylinder 11 which are formed integrally with a crank-case, the crank-shaft bearings are cooled by water which is separated from the water-entraining air discharged from the compressor outlet. In an embodiment, air passes to the low-pressure cylinder 11 through a filter 12 and is passed to the high-pressure cylinder 10 via an intercooler 13. The air then flows from an outlet in the high-pressure cylinder 10 to a combined after-cooler and separator 14, from which water passes through a treatment unit 15 and into a sump 16. The water is pumped from the sump 16 to the bearings by means of a pump 17. The bearings are provided with facings of synthetic resin material or resin bonded metal.

Filed: 1950-07-13
Abstract: 675,440. Mining by rotary boring apparatus. COMPTON, C. E. July 13, 1950. [July 13, 1949; April 19, 1950 ; July 11, 1950] No. 17552/50. Classes 68 (i) and 85. A mining machine head comprises an openended cylinder the rear of which is secured to a portion of the helix of a spiral conveyer that is mounted on a rotatable and advanceable shaft. The leading edge of the cylinder is provided with cutting teeth, a spiral thread on the outside removes rearwardly any gummings that do not pass within the cylinder, whilst the forward end of the helix and shaft taper to form a mounting for a drill bit. As the head is advanced against the face, cutters 9 and 10 cut a circular kerf to permit entry of the cylinder 8 and helix 12. Further advancement causes enlargement of this kerf by cutters 11 disposed on the inner surface, whilst at the same time the bit 7 bores a hole in the centre of the circular mass of mineral being mined, and into this hole follows the tapered helix 3 and shaft 2, the wedging action of which splits the mass radially. The increasing pitch of the helix as it carries the mineral rearwardly prevents jamming of the mineral within the head. In a modified form, the helix is no longer reduced at the tapered portion of the shaft but this tapered portion is replaced by spiral flutes welded thereto. Also, a series of inside spirals are provided on the cylinder. The helical conveyer may rotate independently of the cutting cylinder which is then secured to the flutes of the shaft.

Abstract: 1,218,179. Electro-deposited composite coatings. BRISTOL AEROJET Ltd. April 18, 1968 [April 18, 1967], No.17687/67. Heading C7B. In a process for electro-depositing a composite coating comprising particles in a matrix in which the particles are co-deposited with the metal from a solution in which the particles are insoluble, the solution is circulated through the container in which deposition takes place, gas being admitted to the container to produce a generally upward flow of solution and gas in the vicinity of the surface on which deposition is occurring. As shown deposition takes place upon a cathodic workpiece 12 suspended within a container 1 having a conical base 2. Electrolyte is withdrawn therefrom via pipe 5 and air is sucked into the system via pipe 8, the mixture of air and electrolyte being passed to the container via pump 3 and inlet 4. The metal matrix may be formed of nickel, cobalt, copper, chromium or tungsten-cobalt alloy and the particles may be of zirconium diboride, molybdenum disulphide or tungsten carbide. The composite may include a solid lubricant such as graphite, e.g. to give a coating containing graphite and ceramic particles. The article to be coated may be of steel, non-ferrous material, e.g. light alloy, plastics material, glass or a composited material rendered conductive by incorporation or precoating. Prior to deposition the article may be degreased with trichloroethylene or acetone and cleaned by blasting with alumina shot or with an acid pickle. Areas not requiring coating may be masked. The coating may be used in manufacture of bearings, or in electro-forming.
Patent GB-612987-A (GB)
Title: Improvements in automatic feed mechanism for milling, drilling or like machines
IPC: B23G1/46
Filed: 1946-06-13
Abstract: 612,987. Drilling. GAUVREAU, V. June 13, 1946, No. 17691. Convention date, June 6, 1945. [Class 83 (iii)] A feed mechanism for attachment to a machine feeds a rotating tool to a workpiece at a predetermined substantially constant pressure and rate by means of weights symmetrically disposed in a chamber of double conical proportions formed by two conical members, one of which is axially displaceable with respect to the other when the weights are driven radially outwards by centrifugal force and which is adapted to operate an electromechanical brake to arrest rotation and feeding of the tool at a predetermined position. The conical members 16, 21 and the weights 22 carried in a spacer 23 are rotated by the armature 11 of an electric motor, the shaft 13 of which is keyed to a quill 15 provided with a slot 17 to accommodate a key 18, Fig. 5, connecting an axial extension of the member 21 with a spindle 19 axially displaceable within the quill and having a tool collet 20 at its outer end. The weights 22 have conical ends to provide a rolling contact with the members 16, 21. Mounted on the member 21 is a cylinder 25 enclosing a piston comprising a sealing washer 26 and a supporting structure 27 secured to a member 28 which engages a ground portion 29 of the quill by means of a keeper 30. A spring 31 is interposed between the cylinder and the piston, the latter having an adjustable port 44. Two electric switches are provided, one of which, 33, is operated by the rim 21a of the member 21 engaging a projection 36 on a lever 37 which pivots about a shaft 38 to axially displace a rod 34. The lever 37 is maintained in a normal position by a spring 39. The second switch (not shown) is operated in a similar manner by the member 21 when returning to its undisplaced position. The motor shaft also carries a brake disc 48 having braking surfaces 49, 50 disposed opposite friction members 52, 53. A plate 54 normally applies braking pressure under the load imposed by a spring 55 which is compressed when the coil 56 of an electromagnet is energized to attract the plate. Cooling air is induced through a duct 57 by fan blades 58 and discharged through ports 60. In operation, a main switch is closed, releasing the brake and energizing the motor which imparts centrifugal force to the weights 22 causing displacement of the member 21 and spindle 19 against the spring 31 and the resistance to discharge of air through the port 44, thus advancing the tool to the work until the member 21 engages the projection 36, thus opening the switch 33 to break the motor circuit and apply the brake. The spring 31 then returns the member 21 to its undisplaced position during which the second electric switch is operated to re-start the cycle or, alternatively, to operate some other part of the machine. The rate at which the spindle 19 is advanced is controlled by adjusting the port 44. A positive mechanical stop is provided when the axial extension of the member 21 contacts the end of the chamber in the member 28.
