Title: Cap connection for mine roof support
IPC: E21D17/086
Filed: 1954-01-15
Abstract: 750,706. Mine roof supports. AKT.-GES. FUR UNTERNEHMUNGEN DER EISENUND STAHLINDUSTRIE. Jan. 15. 1954 [Jan. 17, 1953], No. 1249/54. Class 20(2). A mine roof supporting beam 2 which is adapted to be pivotally connected to an already positioned beam 1 and then swung up and locked in a roof supporting position, is provided with a pivoted pawl 3 engageable with an abutment or nose 5 on the beam 1. A locking wedge 8 of hook-shaped section for engagement in a correspondingly shaped slot 7 in the beam 1, is provided with a bolt-like marginal thickening 10 engageable in a cylindrically concave jaw 6, opening obliquely downward in the beam 2, facing the beam 1. After placing a prop beneath the beam 2 the wedge 8 is driven back until its tapered end, which has no bolt-like marginal thickening for about the width of the beam, engages the slot 7, whereby the beams can adjust themselves to variations in the configuration of the roof, and whereby, on recovery of the props of the beam 1, this beam will fall unhindered. The pawl 3 has a stop 11 which can abut against an end face 12 of the beam 2 to limit pivotal movement of the pawl so that it is always in a position to engage when it is to be fitted to a beam 1. The beam 2 can move laterally relative to the beam 1 and such movement may be facilitated by making the surfaces of the jaw 6 or bolt-like portion 10, and preferably also the surface of the pawl 3 or nose 5, of curved form in a transverse direction. End walls 14 on the pawl 3 prevent its lateral disengagement during such lateral movement.

Abstract: 112,060. Clay, J. Jan. 26, 1917. Cow-milkers.-A pulsator for cow-milking apparatus comprises a vertical cylinder b communicating at its upper end a with a vacuum chamber, at its lower end d with the atmosphere, and at an intermediate part e with the annular chamber of a teat cup. A ball c or other piston, freely movable in the cylinder, is lifted in virtue of the vacuum until opposite a recess i; air then passes above the ball, causing it to fall by gravity. The action. which is stated to be continuous, puts the passage into communication alternately with vacuum and air, thereby producing a pulsating effect. Springs at the ends of the cylinder may cushion the movements of the piston. The recess i may be formed in a bar slidable in a longitudinal groove in the cylinder to vary the stroke or speed of operation.

Title: Improved means for testing the balance of rotary bodies
IPC: G01H1/00
Filed: 1930-01-15
Abstract: 346,819. Testing balance of rotary bodies. SCHENCK EISENGIESSEREI UND MASCHINENFABRIK DARMSTADT GES., HEYMANN, H., and OHLY, C., 55, Landwehrstrasse, Darmstadt, Germany. Jan. 15, 1930, No. 1460. [Class 106 (ii).] Means for ascertaining the peripheral position of the mass to be added to obtain balance comprises an elastically mounted mass in addition to the usual balancing structure in which the body to'be tested is mounted, which serves to operate recording means, the elastically mounted mass being connected to the mounting of the body to be tested. In Fig. 1, the shaft a of the body to be balanced is mounted in bearings b supported by blade springs c. The additional oscillating structure consists of a blade spring e and mass # a bent spring recording the oscillations of the structure on the shaft, the deviation in the axial direction being a measure of the magnitude of the vibratory movement. The spring e may be lengthened to amplify the record. By adjusting the dimension of the mass m the natural frequency of the structure e, f may be made to occur at the desired speed of rotation. In another form the mass is longitudinally movable along the blade e which is graduated. In a further form, the adjustment is by varying the clamping position of the spring e. In this form, the recording spring is guided by a light invariable spring or link, and rests on the spring e. Only one half of the oscillation is recorded in this form. In a form shown in Fig. 5, the structure e, # actuates through a guided push rod m, a lever n pivoted at the front end of the rod, a point n<1> making the record. A suitable brake retains the lever n in the position into which it has moved. In a form shown in Fig. 6, the structure e, # is mounted in a narrow tubular casing o which can be introduced through an opening in the machine casing p. The mass # is mounted on a rod q, springs e bearing against the rod of the casing. Two recording springs d are provided each giving a one-way diagram. In a simplification of this form, the mass is carried on a rod introduced through a hole in the casing of the machine and the end of the rod is provided with one inclined blade spring for recording purposes.

Class 40(6) In a gating circuit any component of the gating voltage which would otherwise appear in the output is balanced out by feeding to the output a voltage which is derived from the gating voltage and is of opposite phase and equal in amplitude to the voltage it is required to suppress. Fig. 1 shows a gating circuit in which an input signal at 1 is applied via cathode-follower stage 1A to the gating tube 4 which is gated at its control grid by a gating signal applied from input 7 via stage 9. Any components of the gating signal at 7 which may pass to the output 01 via the interelectrode capacity of tube 4 is balanced out by applying the inverse of the gating signal derived from the cathode of tube 9 via balancing network 14, 15 to tube 18 of cathode-coupled tubes 17, 18. Resistor 15 and capacitor 14 are adjusted to balance resistor 11 and stray capacitor 6 respectively. In a modification shown in Fig. 2 two oppositely directed gating tubes 4A and 4B are employed so that gating by either positive or negative-going gating signals may be used. In a further modification shown in Fig. 3 the balancing circuit 14, 15 is taken direct to one of the output terminals; In further modification Fig. 4 (not shown), the gating tube 4 of Fig. 3 is replaced by two oppositely directed gating tubes.
