Title: Apparatus for recording quick impulses
IPC: G01R13/06
Filed: 1950-08-29
Abstract: 695,883. Recording-apparatus. METRANARODNI PODNIK and BARVITIUS, F. A. Aug. 29, 1950 [Sept. 19, 1949], No. 21312/50. Class 106 (iv). Apparatus for recording rapid impulses in which the speed of the record surface relative to the marker increases during each impulse is characterized in that during the transmission of an impulse the marker support is moved against spring means in the opposite direction to the movement of the record surface by mechanism controlled by means transmitting impulses to the marker and in that the return movement of the marker support under the action of the spring means is slowed down by damping means. An automatic recorder of mine-signals comprises a recording drum 1 driven by clockwork whereon, during several revolutions, a marker 2 traces, in its rest position, a helical line representing lapsed time and during a series of impulses the marker 2 deviates from this line. The marker 2 is carried by a recording block comprising four cross-bars 6, 7, 8, 9 joining side plates and is supported by two flat springs 11, 12 screwed to the cross-bars 6, 9 and to the ends of a base 10. A flat arm 3 carrying the marker 2 is pivoted to a link 4 on the cross-bar 6 and rests on a regulating screw 13 in the cross-bar 9, while the recording block rests with the cross-bar 8 urged against a pillar 14 by a spring 15 linking the pillar 14 to the cross-bar 7. At each impulse to be recorded an electromagnet 16 is excited, causing its armature 17 to rotate about a pivot 18 so that an adjustable stop 19 lifts the arm 3 while an extension 20 of the armature 17 is swung against the action of a spring 22 away from an adjustable stop 23 to cause a pawl 21 to advance a ratchet wheel 24, shaft 25 and crank 27, whereby a rod 28 pivoted on the pillar 14 reacts causing the recording block to move to the right, the resultant movement of the marker being in an oblique line away from the straight line drawn in the interval between one series of impulses and another. When the current is interrupted the parts begin their return movements but the ratchet 24 drives, through a pawl 33 fixed to a gear 26, a gear train and a friction clutch, a damping-propeller 32 so that only a small return movement is made before the next impulse is recorded and thus the series of impulses is recorded as a series of " saw teeth ". At the end of a series the parts will return to rest position slowly at first and later more quickly due to a suitable selection of gear ratios, movement of inertia and surface. The crank mechanism 27, 28 may be replaced by a cam co-operating with the pillar 14 or by a rack and pinion.

Title: Data transmission apparatus
IPC: H04L7/02
Filed: 1965-05-20
Abstract: 1,048,063. Data transmission. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 20, 1965 [May 22, 1964], No. 21312/65. Heading H4P. In a distortion correcting system each data pulse is sampled several times to obtain amplitude samples. The samples are separately amplified to develop an aggregate signal representing the undistorted pulse. The degree of amplification is determined by the results of an operation upon the amplified components. The distortion is corrected either at the receiver or by pre-distorting at the transmitter. In the former case, a test signal 10000 . . . is transmitted. At the receiver, Fig. 1 (not shown), the peak in the distorted 1 bit is detected, 41, and also normalized to unity amplitude, 22. The normalized signal is quantized to provide several samples during the bit. The samples pass to a shift register 30 whose outputs are separately multiplied 36 by factors stored in a gain register 35. The sum of the products represents the undistorted pulse in its most significant digit, and the other digits feed back to adjust the factors in gain register 35, such that the product sum at the remaining sampling times are zero. The product sum also feeds a clock phase-adjusting circuit which changes the clock frequency in accordance with the difference between successive sums.

Title: Calculating device for assisting design of loaded structural  members
IPC: G06G1/14
Filed: 1972-05-09
Abstract: 1392367 Device for loaded beam calculations S C LEWIS 9 May 1972 21574/72 Heading G4B  Relates to calculations involving a beam supported either fixedly or freely at one end, fixedly or freely supported or unsupported at the other end, and loaded either uniformly over its length or by a load applied at a particular point along the length of the beam. Two predetermined constants exist for each of these support and loading conditions. For a particular condition and a known value of loading, the first of the two constants associated with the condition and the loading value are aligned, by adjusting the relative position of two members, respectively bearing a first constant scale and a loading value scale, Fig. 2 (not shown). An array of diagonal parallel lines, corresponding to various values of beam section modulus and borne by one of the two members, is then correctly positioned with respect to a grid, borne by the other member and representing values of beam length versus values of allowable stress. The other side of the assembly of two members can be similarly used, the second of the two constants being aligned with the loading value, the diagonal lines representing moment of inertia values and the grid representing values of beam length versus values of maximum deflection, Fig. 1 (not shown). The two members may be relatively slidable or rotatable.

Abstract: 419,590. Automatic couplings for railway &c. vehicles. SCHARFENBERGKUPPLUNG AKT.-GES., 25, Viktoriastrasse, Berlin. July 26, 1934, No. 21911. Convention date, April 23. [Class 103 (v).] In an automatic central buffer coupling for railway &c. vehicles of the kind in which a coupling-hook pivotally mounted on a rotary disc-hook engages with the disc-hook on the opposed vehicle, damage to the link owing to its projecting from the couplerhead in its non-coupled position is obviated by arranging that the link should be in a different or retracted position relative to that occupied when the vehicles are coupled. In the normal position, Fig. 3, the link b of each coupler is accommodated within the guiding cone n, and the rotary disc-hook a is maintained in the position corresponding by means of a sliding plate l engaging a shoulder g, Fig. 4, on a locking-bar f and retained by a spring k, the plate l being directly connected to a protruding pin i. When the couplers approach each other, the pins i are pressed backward by contact with the cones n, the shoulders g are released, and spring e within the heads are free to rotate the discs into the coupled position, Fig. 5. Guide-surfaces o, p are provided, the former being located in the cones n and the latter projecting from the faces of the couplers.

Title: Improvements relating to brakes
IPC: F16D65/52
Filed: 1946-07-24
Abstract: 614,692. Brakes. PRATT, J. H., and MANLEY, G. E. July 24, 1946, No. 21994. [Class 103 (i)] In a brake having means for automatically adjusting the release position of the shoes to compensate for wear, further means are provided for automatically taking up the clearance between the actuating means and the shoes consequent upon operation of the first mentioned means. The release position of shoe 5, actuated by an expander mechanism 6 of the type described and claimed in Specification 314,607, [Class 103 (i)], in which the wedge faces 6c, 6d are of plungers 6a, 6b are forced outwardly by rollers 13 bearing on an axially movable frusto-conical expander 12, is adjusted by automatic means of the type including a block 15 passing through the shoe to engage the drum 22 when the brakes are applied and abutting in the release position against a stop 16 on the backplate 11, which block is in frictional engagement with the shoe 5. The clearance which would otherwise arise between the plunger 6a and the shoe 5 as a result of this adjustment is taken up automatically by the connection 7, 8 between the shoe and the plunger. The lever 8 bearing on the plunger 6 has an eye 8a which, when aligned with the rod 7a connected by a bracket 7 to the shoe, moves freely thereon, but which when forced out of alignment with the rod binds therewith. A spring 10 pulls the lever 8 along a line substantially axially with respect to the rod 7a. When the plunger 6a is forced outwardly to expand the brake, the eye 8a thus binds on the rod 7a to transmit the applying force to the shoe. When the brake is released, if adjustment of the shoe clearance has occurred, the lever 8 is pulled along the rod 7d by the spring 10 until the upper end of the lever abuts against the plunger 6. Since the expander 6 is floating, adjustment need only be applied to one shoe. The invention is stated to be applicable to brakes applied otherwise than mechanically.
