Abstract: 1,016,456. Grinding. T. BOWERS & CO. (TOOLMAKERS) Ltd. May 26, 1964 [June 14, 1963], No. 23763/63. Heading B3D. A rotary work support table unit capable of being temporarily mounted on the work-table of a machine tool includes a rotary table 6 furnished with a central pendant spindle mounted in ball and/or roller bearings in a housing 9, a worm-wheel 10 on the spindle and a worm 5 meshing therewith, means for driving or transmitting torque to the table through the gear means at substantially low speeds, the table unit being pivotally mounted on a base-plate 1 by means of which it is mounted on the worktable of a machine tool, e.g. a grinding machine, and means for adjusting the unit about its pivotal axis for setting the rotary table at a predetermined inclination. A variable-speed electric motor 3 or air motor drives the worm gearing through coupling 7, 8. The table 6 has a skirt which is a close fit with the top part of the housing, sealing means being provided. The table 6 carries a magnetic or other chuck. The base-plate 1 has split lugs 18 receiving the ends of a fulcrum bar 19 secured to the housing. A sine setting bar normally bears on a slip plate for zero alignment. Slips of predetermined thickness are selectively placed under the bar instead of or in addition to the plate. Reverse inclination is obtained by removing the plate. Oil for the reduction gear is introduced into the housing through an inlet closed by a plug. As the oil will run towards one end of the housing when it is tilted, the worm shaft carries a spinner 29 to circulate the oil. Instead of an electric motor some other torque transmitting means may be used such as a flexible shaft and/or other drive from a part of the machine tool or its driving means.

Title: Improvement in semi-conductor relaxation oscillators
IPC: H03K4/48
Filed: 1950-09-29
Abstract: 684,644. Semi-conductor circuits for generating oscillations. RADIO CORPORATION OF AMERICA. Sept. 29, 1950 [Sept. 30, 1949], No. 23919/50. Class 40 (vi). A relaxation oscillator comprises a crystal triode having an output impedance connected in the collector electrode circuit and an inductor in circuit with the base electrode. Fig. 1 shows a pulse generator in which a transistor employing a semi-conductor 10 such as a germanium crystal has an inductor 22 in the base electrode circuit and is biased in conventional manner; it is stated that the circuit oscillates at a frequency determined by the value of inductor 22 and by the resistive load which the crystal triode presents which determines the decay time of the voltage developed across the inductor. It is shown that the collector voltage has a pulsating waveform, the operation of the oscillator being controlled essentially by the current flow through inductor 22, the frequency of oscillation being considerably below that of a sine-wave oscillator having a resonant circuit comprising inductor 22 tuned by the associated stray capacity. The output pulses produced across load resistor 15 are differentiated by network 25 and the resulting sharp pulses appear at the output terminals 24. The oscillator may be synchronized by applying negative pulses to the base electrode or positive pulses to the emitter electrode, Fig. 3 (not shown), so that the oscillator is triggered slightly ahead of the time when the circuit would normally reach the regenerative region. The oscillator may be made normally quiescent by adjustment of the emitter and collector bias voltages and triggered into oscillation by the application of a pulse train to either its base or emitter electrodes. Fig. 4 shows a modification for generating a sawtooth output voltage in which capacitor 45 is slowly charged negatively from source 14 via resistor 15 and is rapidly discharged via the transistor. The time constant of network 15, 45 is such that the voltages of the collector and base electrodes decrease in unison during each cycle so that the oscillator reaches the regeneration region, as determined by the collector and base potentials, simultaneously. The oscillator may be triggered by positive pulses applied to the emitter electrode 11, the frequency of the input pulses may be an integral multiple of the free-running frequency of the oscillator so that the circuit operates as a frequency-divider.

Patent GB-245520-A (GB)
Title: Improvements in liquid fuel supply arrangements for internal combustion engines
IPC: F02B1/00
Filed: 1924-10-09
Abstract: 245,520. Jones, F. J. S. Oct. 9, 1924. Actuating by air pressure and weights; buckets; regulating delivery by varying speed and power of motor. -In a pump for raising liquid fuel for internal-combustion engines from a low-level tank to a higher level, in which the engine suction actuates a piston 12 connected to a pump plunger 4 of smaller diameter which delivers the fuel into a chamber 1 forming part of the device, the operation of the pump is automatically interrupted, when a predetermined supply of liquid has been raised, by a float or other means independent of the pistons. The fuel is always under atmospheric pressure in the chamber 1 from the outlet 3 of which it flows to the carburettor by gravity. In one form, Fig. 1, the pump plunger 4 works in a cylinder 5 and is connected by a link 9 to the rod 10 of the piston 12, which works in a cylinder 13 and is acted upon by engine suction and by a spring 14. Above the cylinder 13 is a valve chamber 16 connected to the engine inlet manifold and to the atmosphere by ducts 15, 18 opening into a valve seating 21. A ball valve 19, alternately closing one or other of the ducts 15, 18, is engaged by a roller 22 carried by a lever 23, which is pivoted to an arm 24 on a spindle 25 controlled by a torsion spring 26 and is engaged by a stirrup 27 on the piston 12. The movement of the lever 23 is limited by stops 42. The duct 18 is connected to the fuel chamber 1 by a pipe 28 adapted to be closed on a valve 17 carried by a float 31. When the fuel in the chamber 1 is above a predetermined level, the float valve 17 closes the pipe 28 and stops the actuation of the pump. In a modification, Fig. 3, the piston 12 is loaded by a weight 40 instead of a spring. A roller valve 19<a> is employed and the movement of the lever 23 is limited by cranked portions 43a of a removable pin 43, the rear end of the lever 23 being seated in the end 44<a> of a leaf spring 44. To prevent the lever 23 from becoming jammed, a leaf spring 23<b> thereon is adapted to be engaged by the lower of two abutments 45b. A float 51 in the chamber I is supported by links 52, the centre connections 52<a> of which engage an abutment 53 on the plunger rod 45 and stop pumping when the fuel level rises sufficiently. The plunger 4 fits loosely on the rod 45, leaving an annular fuel-admission space controlled by a ring 47 resting on a conical seating 46 on the rod 45.

[Class 83 (iii)] The feed limiting device of the parent Specification is provided with a setting element whereby the controlling recesses on the auxiliary control drum may be brought to a zero position to facilitate adjustment. The stop drum 60 and control drum 61, Fig. 1, are connected in this embodiment by gearing 91, 93, mounted in a housing 95 adapted to pivot, Fig. 3, to disconnect the drive. A screw 99 is turned to effect this and a spring plunger 97 returns the gear housing when the screw is withdrawn. The auxiliary drum may be turned by means of a hand wheel when the drive is disconnected and after loosening the control discs 61 a setting element 101 is moved, by means of a rack and pinion controlled by a hand wheel 103, across the peripheries of the discs consecutively to engage grooves 104 in the discs, thus bringing all the discs into a zero position. Further setting may then be effected by a vernier disc on the shaft of the auxiliary drum so that the stop levers 45 are released at the required positions of the machine carriage. A latch member 49 may be turned by hand to render selected levers inoperative, or this member may be coupled for that purpose to a turret head to work in conjunction therewith.
