Title: A machine tool having a worktable arranged to be rotated by indexing mechanism
IPC: B23Q39/04
Filed: 1958-03-07
Abstract: 869,182. Drilling-machine details. WITZIG, K. E., and FRANK, R. March 7, 1958, No. 7441/58. Class 83 (3). In a drilling &c. machine, means for controlling the indexing mechanism of a turntable 16 so that it will remain inoperative while the operator is mounting work 12 on the table, irrespective of whether an indexing signal is received before the work-mounting operation is finished, comprises a source 1 emitting a beam 5 which is interrupted by the presence of the operator mounting the work on the table, and a relay 7 operated by the beam when the operator moves out of its path. The light source 1, mirrors 2, 3, 4 and relay 7 are carried by brackets on one side of the machine, the other three sides being occupied by multi-spindle drill-heads (Fig. 2, not shown). Fig. 3 illustrates the setting of the control circuit as the table 16 is being indexed by a motor 17, driving through gearing 18 and a worm 19. The motor is energized by a circuit 62 connected to the motor by a switch 39 which is operated by a pivoted member 37 connected by a link 33 to a spring 35. The switch is held in the position depicted by contact between a projection 34 on the link and a pin 31 on the armature 30 of an electromagnet 29, the circuit of which was opened by a switch 25 operated by a solenoid 24. Energization of solenoid 24 is by closure of a switch 21 operated by withdrawal of the tool-spindles. In Fig. 3, 41 is the light source 43, 44 the mirrors and 45 the photoelectric cell operated by the rays to energize a solenoid 48 for withdrawing its armature 47 from the path of movement of that of solenoid 24, thus permitting movement of armature 23 to open switch 25 when switch 21 is closed. Opening of switch 21 permits a spring 61 to close switch 25, which energizes the magnet 29, withdrawing pin 31 and allowing spring 35 to open motor switch 39. If the operator obstructs the light rays 42, the resulting extended position of armature 47 prevents the opening of switch 25 by closure of switch 21 until the obstruction is removed. A number of oppositely disposed light sources and photo-electric cells may be used (Fig. 4, not shown).

Title: Process and apparatus for making glass cylinders or tubing
IPC: C03B17/04
Filed: 1937-03-13
Abstract: 472,525. Making glass cylinders and tubes. CORNING GLASS WORKS. March 13, 1937, No. 7463. Convention date, April 10, 1936. [Class 56] A process for making a glass cylinder or tube having a predetermined internal configuration consists in flowing a hollow stream of molten glass and then introducing into the stream a mandrel adapted to produce the configuration, the mandrel being removed after the glass has cooled. The stream of glass flows downwards from an opening, surrounded by an annular kerb 23, in the centre of a rotating bowl 22 into which the glass flows from a furnace, as described in Specification 378,291. A cover 27 over the bowl has a central opening through which a sleeve 28 extends downwards towards the surface of the glass. A tubular rod 38 is moved axially through the sleeve by a pair of friction pulleys 36, 37 which are driven by a motor 34 supported above the cover 27. The mandrel 40 is attached to the lower end of the rod 38 by means of radial prongs 46 which are turned by levers 51, 52 to lock or release the mandrel. In operation, as the stream of glass flows downwards from the kerb 23, the mandrel 40 is lowered, into the stream of glass which forms a coating on the mandrel. After the mandrel is coated completely, it is detached from the rod 38 and allowed to fall, the stream of glass being severed above the mandrel. The ends of the glass coating are then removed and the mandrel, which has shrunk in cooling, is withdrawn from the tube. The apparatus may be operated continuously by introducing a succession of mandrels into the glass stream.

Abstract: 988,424. Power-assisted master cylinders. H. TEVES, E. A. TEVES, and M. TAUSEND, [trading as ALFRED TEVES MASCHINEN-UND ARMATURENFABRIK KOMM. GES.]. Feb. 28, 1962 [March 30, 1961], No. 7817/62. Heading F2F. A power-assisted master cylinder comprises a piston 11, a pedal operated actuating member 23, and means for circulating pressure medium from a first source 1 between the facing ends of the piston provided with an axial movable valve seat member 13 and member 23 so that on axial movement of the member 23 circulation of the pressure medium is throttled between the facing ends to operate the piston. A connection 26, 40 is provided between the location of throttling and a second pressure source 3 which has a cut-in valve 36 operable by movement of the member 23 during failure of the first pressure source to actuate the piston. As shown, pressure medium flows from a pump 1 via a charging valve 2 for an accumulator 3 to a port 30 and thence through passages 31, 33, 34 and port 28 to a tank 4. When the pedal 6 is pressed rod 7 moves member 23 towards the valve seat 13. The flow of pressure medium is throttled so that some returns to the tank 4 via passages 33, 34 and the remainder acts upon the end face 18 of the piston 11 and thrusts the same into the cylinder 10. If the pump fails movement of the member 23 firstly pushes the valve seat 13 into the piston 11 so that collar 17 engages the end face 18 of the piston and then causes the tappet 38 to be raised by means of rod 14, lever 42, and ledge 29 which lifts the spring-loaded valve 36 from its seat. Pressure medium flows from the accumulator into passages 40 and 31 and acts on the piston 11. Should both the pump and accumulator fail the member 23 engages the valve seat 13 when the pedal is pressed so that the valve seat is forced against the pressure of the spring 47 into engagement with the piston 11 which is thereafter operated mechanically.
