Granted: 1966-10-07
Abstract: 1,104,109. Drilling. L. KLEIN. 10 Nov., 1965 [2 Dec., 1964], No. 47722/65. Heading B3C. [Also in Division B5] A clamp for applying hold-down pressure to a workpiece 14 on a working surface 11 during a drilling operation comprises a base mounting member 19 adapted to be attached to the working surface, an elongated pressure beam 24 adjustably mounted on the base mounting member, a gripping block 35 mounted on one end of the pressure beam and having a bore therein for receiving the spindle 36, Fig. 4, of a work clamping assembly 35, a bearing contact sleeve 37 in coaxial surrounding relation to the spindle and disposed between the spindle and the inner surface of the bore 39, a plurality of bearing members 41 carried by the sleeve in circumferentially spaced bearing relation between the spindle and a flared portion 40 of the bore, and resilient means 42 acting between the sleeve and gripping block to bias the flared portion against the bearing members to press them against the spindle. The base mounting member 19 is secured by a screw 22 to the table and carries an upstanding post 20 on which is a clamp 21 for the pressure beams 24. One end of the beam carries the gripping block 35 in which the sleeve 37 is mounted, the sleeve having apertures for locating the bearing members which are in the form of balls 41, a spring 42 acting on the sleeve to urge the balls against the flared portion 40 of the block and against the spindle 36 which is located in the sleeve to lock the spindle in its adjusted position. The lower end of the spindle supports a holddown shoe 49, Fig. 7 (not shown), which is carried by a pin 50 engaging a slot 58 in the bifurcated end of the spindle and can be urged downwardly to engage a workpiece by a lever 48 formed with a cam surface 56 engaging the shoe. In operation, the clamp 21 is released to permit adjustment of the position of the clamping assembly 35 over the workpiece and retightened. The spindle 35 can be moved downwardly by applying pressure to a cap 46 on the upper end of the spindle so that the shoe engages the workpiece, the balls permitting downward movement of the spindle but resisting upward movement until the sleeve 37 is lowered relative to the gripping block. Increased pressure of the shoe against the workpiece may be obtained by deflecting the beam upwardly by pulling the gripping block 35 upwardly as the spindle is pressed downwardly. Still further pressure may be applied by movement of the lever 47 causing the cam surface 56 to press the shoe 49 downwardly relative to the spindle 36. Springs may be disposed in the slots 58 to urge the shoe to its upper position. The sleeve 37 may be moved to release the balls 41 by manual pressure or by a cam acting on a flange 44 of the sleeve. The shoe member may be flat, as shown, or have an inverted V configuration for holding rods, have a pointed shape to effect centring of a workpiece, or have a roller surface for guiding moving material.

Abstract: 1,125,676. Photo-electric measurement of high voltage systems. BROWN BOVERI & CO. Ltd. Feb.1, 1967 [Feb.3, 1966], No.4909/67. Headings G1A and G1U. [Also in Division G2| Measured values are transmitted from a region of high potential to a region of low potential by causing the measured value to modulate the position of a mirror which modulates interferometrically a monochromatic light beam emitted from and received at the region of low potential. Light from a gas laser is transmitted by an optical fibre 10 to an interferometer 7 in the vicinity of a high voltage conductor the current wherein is to be measured. The light beam is split by a Koesters prism 19 to provide beams which are reflected by mirrors 16 and 17 on to a fixed mirror 21, which causes the beam to retrace its path. The portion of the output of a transducer measuring the conductor current is picked off by a temperature variable potentiometer, integrated and applied to electrostrictive converters 14, 15 to modulate the position  of the mirrors 16, 17 in antiphase to produce a pulsating light intensity in the divider plane 20 of the prism 19. A 90 degree phase plate 23 covers half of the beam to mirror 16, so that the pulsation of two halves of the combined beam are 90 degrees out of phase. These halves are transmitted by optical fibres 11 to photo-detectors 26, 27, Fig.4. The outputs of detectors 26 and 27 are mixed at 30 and 31 with carrier signals in quadrature from an oscillator 28. The carrier components are removed at 32 and 33 and the modulated signals added at 34 to give a signal which is frequency modulated with the measured current signal. This signal is detected by an f. m. demodulator 38 and fed to an indicator 39 or recorder 40.

Title: Improvements in or relating to matrix-memory arrangements
IPC: G11C11/06
Filed: 1959-01-02
Abstract: 858,260. Circuits employing bi-stable magnetic elements. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 2, 1959 [Jan. 7, 1958], No. 206/59. Class 40 (9). [Also in Group XIX] Read-out from a matrix of saturable reactors is followed immediately by back-recording and is characterized by the provision of a gate circuit between each reading conductor and its related amplifier, said gate circuit being blocked during back-recording. Binary information is entered into cores K11-K14, K21-K24, K31-K34 in known manner. A reading pulse applied to one of the vertical conductors, say BV1, produces an output pulse on each horizontal conductor, say L1, corresponding to a core K11 which has been set, the said core being simultaneously restored. This output pulse passes through transistor T1, transformer TR1 and amplifier A1 to set a bi-stable trigger device F1 The reading pulse is followed by an oppositelypoled read-back pulse on lead BV1 and lead BK, the latter passing through gate P1 to the read conductor. Transistor T1 is biased by F1 to have a high resistance if F1 has been set to 1. The read-back pulses are thus permitted to follow the read-out pulse very quickly.

Filed: 1931-01-09
Abstract: 356,080. Flexible shaft couplings; claw clutches. AXIEN, L., 66, Bebelallee, Altona-on-Elbe, Germany. Jan. 9,1931, No. 821. Convention date, Jan. 10, 1930. [Class 80 (ii).] A flexible shaft coupling, which may be modified for use as a claw clutch, comprises radial blade or laminated springs acting first as cantilevers and then, under greater load, as beams supported at both ends. As arranged for bidirectional drive, the driving-member a, Fig. 2, carries pairs of projections c, c<1> with curved contact faces k, kl, these projections lying between inner and outer sets of projections e, f, Fig. 3, on the driven member b, which carries blade springs d free to oscillate about their inner ends when unloaded. Under load, the projections c or c<1> press the springs against increasing areas of the faces l or l<1> of the projections e until, as shown in Fig. 6, their ends abut .against the faces m of the projections f or of slots in a circumferential flange, whereafter the springs are bent around the faces k or k<1> of the driving-lugs. Under normal torque, clearances o, p, q remain between the springs and edges of the projections, but on considerable overload they contact with the full area of the projections and transmit drive in double shear. For dismantling, the springs are withdrawable radially on removing an enclosing- shell (not shown) for retaining the springs and lubricant. In small couplings, a single spring or pack of springs extending diametrically is used, but in larger couplings additional radial springs bearing at the centre on the diametral spring are used, as shown in Fig. 3. Radial play is provided between the projections. By increasing the spacing of the lugs c, c<1> and making one member slidable on its shaft, the coupling can be used as a claw clutch.
