Title: A hank twisting machine
IPC: B65H54/56
Filed: 1950-12-04
Abstract: 698,503. Twisting hanks. BATES. E. B. Dec. 3. 1951 [Dec. 4, 1950], No, 29673/50. Class 120(iii) A machine for twisting hanks of yarn comprises two spaced holders for the reception of a hank, means for effecting relative rotation between them to twist the hank and to produce a loop or eye in one end of the twisted hank, and means for doubling the twisted hank on itself to bring it end to end and for inserting the other end through the eye. As shown, a hank 9 is placed on holders 1, 2 and holder 1 is rotated by a spindle 3 to twist the hank. The hank-receiving element 6 of holder 1 is of arcuate form so as to produce an eye 11 at the end of the hank. After the hank has been twisted, holder 2 is swung up through 180 degrees about an axis 5 until the end of holder 2 enters the concavity of element 6 and a protrusion 8 on holder 2 carries that end of the hank through the eye 11 at the other end, the hank being doubled about a peg 12 which is in the raised position shown in Fig. 9. Holder 2 now swings back to its initial position and a series of fingers 13 fixed on a shaft 14 swing upwardly to sweep the twisted hank off element 6 and peg 12 on to a table 15; peg 12 then moves to a lower position shown in Fig. 1 to allow a fresh hank to be placed on holders 1, 2. Peg 12 presses resiliently on the hank as it is being twisted, and is capable of yielding slightly towards holder 1 during doubling, so that both twisting and doubling are effected under tension. For varying the spacing between holders 1, 2, holder 2 is carried on telescopic axis 4 and holder 1 may be adjstable axially of spindle 3. The machine is driven by a motor 17, rotation of spindle 3 and movements of holder 2, peg 12 and fingers 13 being , controlled in timed relationship from a cam shaft which also causes table 15 to rock periodically so as to cause a twisted hank thereon to slide to the back. The drive to spindle 3 is transmitted through a clutch which is caused to slip after the desired number of twists have been imparted to the hank, means being provided for varying the number of twists imparted and for arresting holder 1 with element 6 in the position shown.

Abstract: 444,464. Electroplating. SCHERING- KAHLBAUM AKT.-GES., 170, Mullerstrasse, Berlin. Oct. 28, 1935, No. 29761. Convention date, Oct. 26, 1934. [Class 41] Plating baths which have been in use for some time are treated with materials of high surface activity such as fuller's earth, silica gel or activated charcoal. Pitting in the deposit is thereby prevented. The materials known by the Registered Trade Marks "Frankonit" and "Carboraffin" may be employed. The materials may be added as a powder, paste or suspension, from which adsorbed gases have been removed. If the materials are such as migrate under the influence of an electric current, they should be removed before plating ; otherwise they may remain in the bath. Alternatively, the electrolyte may be passed through a filtering layer of the material. The materials may be employed in conjunction with further additions such as metal hydroxides, carbonates or silicates and oxidizing agents such as persulphates or percarbonates. Detailed examples for the treatment of nickel and copper baths are given.

Title: Digital clutter rejection in a pulse radar system
Inventor: ESCHNER ALBERT
IPC: G01S13/64
Filed: 1968-06-24
Abstract: 1,224,531. Pulse radar. HUGHES AIRCRAFT CO. 24 June, 1968, No. 30086/68. Heading H4D. In a system for processing radar video received as a plurality of signal sweeps in response to a selected number of transmitted pulses an encoder 20, Fig. 2, converts the radar video into digital signals, a digital cancellation stage 24 includes at least one cancellation unit 32a, 32b, Fig. 4, and a digital data processor 30 incorporates a plurality of means for storing the output of the cancellation stage representing radar video from selected radar repetition periods and incorporates means for serially reading out the digital signals from each radar range received during each of the selected radar repetition periods. Only one Doppler filter bank is then necessary, unlike prior art (Fig. 1, not shown) which has a filter bank for each radar range "bin". The invention affords clutter rejection. High or low pulse repetition rates may be utilized. Timing of the transmitted pulses, of the sampling clock pulses to encoder 20, of the sweep selection gate 26 and of processor 30, is afforded from a control circuit 22. In the embodiment encoder 20 affords a series of digital multi-bit produced at a sampling frequency f s  which is at least (1/d) where d is the transmitted pulse width. The cancellation stage has two cancellers in series, Fig. 4; if the signal from encoder is M bits, a set of M parallel delay (e.g. magnetostrictive) lines are provided in block 32b but it is stated that (a) less than M bits, and hence fewer delay lines, are needed in unit 34a and (b) the output from unit 34 need be even less bits, e.g. if M=8, there need only be four bit signals fed into gate 26, Fig. 2. Gate 26 selects the number of sweeps P in a given number N thereof to minimize the effect of clutter frequency spectrum spreading due to a finite value of N; the theory is explained, Fig. 5 (not shown). Processor 30, Fig. 6, comprises for each of the four bits a number P of digitized sweep delay lines 61-65 and a shift register 66, the outputs of all shift registers being fed to a decoder 70 which is followed by a single bank of Doppler filters. Weighting by unit 72 of the amplitudes of signals may be added to further minimize spreading of the clutter spectrum into the Doppler filters.

Abstract: 849,380. Fluid-pressure servomotor control systems. NEW YORK AIR BRAKE CO. Sept. 23, 1958 [Sept. 23, 1957], No. 30317/58. Class 135. The displacement of a swash plate motor or, as shown, a pump, is controlled by a power device 19 which opposes a spring plunger that biases the swash plate towards its maximum displacement; the supply of fluid to the device 19 is controlled by a valve having passages 24, 25 and 26 connected to the pump discharge, the interior of the pump housing and the device 19, respectively. In the valve casing 23 is a sleeve 32 embodying ports 33, 34, which open to the passages 26, 25, respectively; a valve closure 35 slidable in the sleeve is provided with lands 36, 37, 38 separated by grooves 39, 41, the land 38 containing a slot 42 connecting the groove 41 and passage 24. The left-hand hemispherical head 43 of the closure 35 supports a block 44 for universal movement, in which block is fixed a piston 47 having a working space 50 and a spherically ended piston rod 48; the closure 35 is urged to the right by a spring 49. A passage 51 interconnects the space 50 and port 33. With the pump at rest the spring 49 urges the parts to the position shown wherein the device 19 is vented via ports 33, 34 and groove 39 to passage 25, and the swash plate is moved by the spring plunger to maximum displacement. With the pump running the pressure in the passage 24 moves the closure 35 leftwardly and as this pressure increases so the closure is moved further leftwards into the lapped position with the land 37 interrupting communication between ports 33 and 34. A further pressure increase displaces the closure still further leftwards until passages 26, 51 are connected to passage 24 by port 33, groove 41 and slot 42 so that the pressures in the device 19 and space 50 also increase, and, together with the spring 49, urge the closure 35 rightwardly into the lapped position when the sum of such restoring forces equals the opposite force on the right end of the closure due to the pump discharge pressure. When the pressure in the device 19 is sufficient to overcome the spring plunger any further increase in pump discharge pressure will move the swash plate towards the position of minimum displacement.
