Abstract: 998,082. Folding edges of non-metallic sheet material. A. M. DANTHONY. Feb. 20, 1964 [Feb. 21, 19631, No. 7208/64. Heading B5K. In a method of folding the ends 2a of a woven label 2, the label 2 is placed lengthwise on a fixed plate 1 having tapered end edges 1a and a length less than that of the label 2 so that the ends 2a project beyond the edges 1a, and two gripper devices 3 each having an opening 4 of V-form are given a combined descending and approaching movement so that, in a first phase, the ends 2a are forced downwardly and, in a second phase, the ends 2a are folded by applying them forcibly against the tapered edges 1a. Each device 3, which may be heated, comprises two plates 3a, 3b fixed by a bolt 6 to a holder 7 freely pivoted about a shaft 8 on an arm 9. A spring 10 fixed between the holder 7 and the arm 9 urges the device 3 downwardly. The arm 9 is freely pivoted on a fixed shaft 11 and urged inwardly by a torsion spring 12. A lug 13 is mounted on the holder 7. and moves in front of a fixed stop 14 and a movable stop 16 on the arm 9. The spring 12 causes a roller 17 on an extension of the arm 9 to bear against a plate 18 constituting the movable element of a deformable parallelogram formed of two links 19 pivotable about fixed pivots 20. One link 19 is extended by a lever 21 which bears against a cam 22. Initially, Fig. 2, the plate 18 is raised and the arms 9 are held spaced with the lugs 13 bearing against the stops 14. The cam 22 causes the plate 18 to descend and the arms 9 are moved by the springs 12 about the shafts 11 to approach one another simultaneously with the springs 10 causing the devices 3 to rock downwardly due to the lugs 13 becoming spaced from the stops 14. As the plate 18 continues to descend the devices 3 continue to approach each other but the downward rocking thereof is stopped by the lugs 13 bearing against the stops 16 so that the ends 2a become folded beneath the plate 1, Fig. 4, and a strong pressure is applied thereto to form a permanent crease. As the cam 22 continues to rotate the plate 18 is raised and the parts return to the position shown in Fig. 2 so that the label 2 can be released and replaced. One of the struts 15 on which the fixed stops 14 are mounted may be mounted on a slide 23 so that its position is adjustable according to the length of the label to be folded. In a modification (not shown) the movable stops 16 are omitted and the downward rocking of the devices 3 is limited by extending the plates 3a so that these plates, on being lowered, rest on the plate 1.

Title: Purification of streptomycin
IPC: C07H15/238
Filed: 1947-03-17
Abstract: Streptomycin is purified (decolourized and freed from histamine-like substances) by extracting a substantially neutral aqueous solution thereof with phenol (preferably about 90 per cent aqueous phenol), at any desired stage in the concentration and purification, but preferably using a partially purified concentrate, e.g. by treating a solution prepared by dissolving in water a crude streptomycin salt (e.g. streptomycin hydrochloride having an activity of 200-300 units per mg., or streptomycin sulphate) and adjusting the pH to about 6.5, after filtering, if necessary, through a filter aid such as diatomaceous silica.  Preferably the aqueous solution is extracted with a water-immiscible solvent (e.g. isoamyl alcohol, followed, if desired, by ether) to remove residual phenol, and may then be evaporated to dryness (e.g. freeze-dried).  A further yield of streptomycin may be obtained from the organic solvent extract by washing with water, and, if desired, again extracting the washings with phenol.  Examples illustrate the various features of the invention.

Title: Improvements in and relating to apparatus for measuring impedance
IPC: G01R27/02
Filed: 1946-03-09
Abstract: 609,268. Impedance measurements. BENJAMIN, R., and BUCKINGHAM, J. March 9, 1946, No. 7444. [Class 37] Apparatus for measuring the values of resistors and, on the same scale, the surge impedances of balanced and unbalanced transmission lines comprises means for applying a current pulse to a network incorporating the impedance under measurement, means for integrating the resultant voltage changes across the network, and a meter for indicating the value of the integrated voltage. A blocking oscillator V1 produces voltage pulses of, say, four microseconds duration at a frequency of 50 kilocycles per second which are applied to the grid of a valve V2 so as to cut off the standing current therein for the duration of each pulse. A constant negative current pulse is thereby produced across a fixed resistor R1 forming an anode load for the valve V2. The resistor R1 is shunted by the transmission line L under test, and a positive voltage pulse is therefore produced at the anode of the valve V2, the value of which depends on the value of the resistor R1 and the surge impedance of the line L. The anode of the valve V2 is connected to a diode V3 which integrates the voltage changes at V2 and controls the cathode current to a cathode follower V4. The cathode current is proportional to the surge impedance of the line L and is indicated on a milliammeter M. To calibrate the milliammeter M the line L is disconnected, and zero reading is obtained by adjustment of a backing-off potential divider R3. A resistor R2 is then put in parallel with the resistor R1 by a switch Sand the screen voltage of the valve V2 is adjusted by means of a rheostat R4 to take account of variations of valve characteristics and supply voltage.
