Title: Reciprocating tool slides on machine tools
IPC: B23Q5/34
Filed: 1972-05-08
Abstract: 1360123 Adjustable ecceritrics WERKZEUGMASCHINENKOMBINAT "7 OKTOBER" BERLIN VEB 8 May 1972 21380/72 Heading F2K [Also in Division B3] A means for imparting variable stroke to the reciprocating tool slide of a machine tool, e.g. in a grinding machine, comprises a shaft 5, driven by an infinitely variable speed motor (not shown) through pulley 7 and having a helical thread on which an eccentric nut 1 is mounted. About this nut 1 is an external eccentric 2, affixed to a wheel 3 which has teeth engaging with teeth on a member 4 which rotates with shaft 5. The shaft 5 is movable axially in one direction by a piston 10, and in the other by a piston 9. Axial movement of the shaft 5 causes nut 1 to rotate by virtue of the helical thread, relative to both the shaft and the external eccentric 2, varying the eccentricity of the combination of eccentrics as sensed by one end (roller 15) of a lever 14 whose other end controls movement of the tool slide 20 (permanently biased by piston 12). The lever is pivoted in a housing 13 which can be rocked (on bearings 26, 28) about the axis of shaft 5 by a cam 17 which in changing the pivot position alters the range of movement of the tool slide 20. The piston 9, which is adjustable through a screw 8 to control the maximum eccentricity is permanently biased towards the zero eccentricity position of the device, so that this is attained whenever no pressure fluid is supplied to piston 10.

Abstract: 961,125. Separating particles from gases. AMERICAN AIR FILTER CO. Inc. May 29, 1963 [June 6, 1962], No. 21489/63. Heading B1T. A separator for separating solid and liquid particles from gas comprises at least two layers 16, 17, Fig. 2, of flexible filter media positioned face to face so as to provide therebetween an interface and formed as a pocket through which the gas is passed, the layer 16 comprising a bed of finely-divided, low density fibrous material, preferably odourless acid-resistant glass, the fibres of which are interspersed between the faces of the bed and are of sufficient diameter to form a maze of indeterminate liquid drain channels communicating with the interface so that liquid particles separated from the gas drain by gravity to a collecting point. The filter media is in the form of a filter cartridge 15, Fig. 1, which is pleated to form a plurality of pockets having mouths at the bottom end thereof, the mouths being kept open by a support member 14. The latter is slidably supported by guide rails 13 mounted in a housing 2 having a dirty gas inlet 3 and a clean gas outlet 4, a scroll fan 9 driven by a motor 11 being disposed at the gas outlet for drawing gas through the housing. The separated liquid particles are collected in a section 6 of the housing 2 having a drain outlet 12. The layer 16 is disposed upstream of the layer 17 and a scrim backing material 18 is provided downstream of the layer 17. The interface between the layers 16, 17 is of a slightly fuzzy nature so that point contact is made between the layers. The layer 16 is preferably formed of fibres having a diameter of 10 microns to 50 microns interconnected by a binder, e.g. starch.

Title: Controlled frequency power supply system
IPC: H02J3/08
Filed: 1960-06-20
Abstract: 946,556. Changing frequency. SPECIALTIES DEVELOPMENT CORPORATION. June 20, 1960 [July 6, 1959], No. 21523/60. Heading H2F. A three-phase frequency-changing arrangement comprises a three-phase source 10 at frequency f 1  and an impulse generator 25 providing pulses at a frequency f 2 , the two frequencies being combined in switching circuits 16-24 to give an output comprising frequency components f 1 +2f 2  and f 2 -f 1 , the latter of which is applied to a load 15. A signal from load terminal 11 is fed back to a frequency discriminator 45 whose voltage output is a measure of the frequency f 2 -f 1 , and this is fed to the generator 25 to control f 2  so that f 2 -f 1  is constant despite variations in f The supply to generator 25 is derived from the source 10 through rectifiers 46. In more detail (see Fig. 3), the source 10 provides waveforms A, B, C, and the generator 25 provides pulse trains D, E, F, each pulse extending over 120 degrees of the f 2  cycle and the three trains being mutually displaced by 120 degrees. The waveforms A and D are applied to switching circuit 16 which allows the passage of that portion of the waveform A arising during the pulses D and gives a waveform G. Similarly, waveform H is derived from waveforms B and E in the circuit 20, and waveform J from the waveforms C and F in the circuit 24. The waveforms G, H, J are added by interconnection to give an output K whose highfrequency component is removed by a filter 34 allowing the waveform L at frequency f 2 -f 1  to pass to load terminal 11. Similarly, by proper combination of the waveforms A, B, C, D, E and F in the remaining switching circuits the other two phases at frequency f 2 -f 1  are passed to the terminals 12 and 14. The pulse generator 25 comprises a multivibrator providing a square waveform at frequency 3f 2  which is differentiated to give positive spikes at frequency 3f 2  which are applied to a ring of three counter having 3 outputs. A rectangular pulse is produced in one of these outputs between the first and second spike, in the second output between the second and third spike, in the third output between the third and fourth spike and so on to give the waveforms D, E and F. The switching circuits (Fig. 2, not shown), each comprise a bridge circuit of diodes which allows the input waveform to pass from one corner to its opposite corner only when a transistor connected between the other corners is rendered conductive by a pulse from generator 25 applied to its base-emitter circuit.
