Abstract: 1,259,204. Purifying cephalosporin antibiotics. ELI LILLY & CO. 10 July, 1969 [10 July, 1968], No. 34874/69. Heading C2A. A method for freeing a mixture of cephalosporin and penicillin antibiotics from penicillin biological activity comprises treating the mixture with a 2-mercaptoamine of formula  wherein R<SP>1</SP> and R<SP>2</SP> are hydrogen or C 1- C 9  alkyl, and R<SP>3</SP> is hydrogen, -COOH or a salt thereof or COOR where R is C 1 -C 9  alkyl, at a pH of 4 to 9 and a temperature of 20-40 C.  using a molar ratio of 2-mercaptoamine to penicillin of at least 1. The process is preferably performed in aqueous medium or in a mixed aqueous-organic medium of water with ethanol or dioxane. Preferred mercapto-amines are 2-aminoethanethiol, 2-dimethylamino-ethanethiol, cysteine or its ethyl ester, N-butylcysteine and 2-(N-hexylamino)ethanethiol. The penicillin activity is destroyed due to reaction with the mercaptoamine with opening of the #-lactam ring to give an amide derivative.

[Also in Division D1] A method of making a heald comprises producing a unitary metal blank having an elongated centrally located slot and forming a terminal eye at at least one end of the blank. Round steel wire stock is rolled to a flattened cross-section and longitudinal notches 9 are formed therein at regular intervals by tools (7), (8), Fig. 2 (not shown). The notches are expanded by a tool 10, which also places a thread eye insert member 12 in the slot so formed, the member 12 being subsequently secured as by soldering. Individual healds are separated by cutting the steel stock generally midway between the slots. To form a terminal eye 30 one end of a heald 4<SP>1</SP> is bent between movable pins 17, 18 and tools 15, 16. In second and third stages, the offset portion 19 is located between pins (17<SP>1</SP>), (18<SP>1</SP>), which correspond with the pins 17, 18, and the leg 21 is twice bent through 90 degrees by tools (22), (23) in succession, Figs. 6, 7 (not shown). The eyes 30 are additionally stamped to give them a precise inner shape. The heald may also be made from band steel stock and the terminal eyes are formed by punching a narrowed terminal portion (37<SP>1</SP>) which is then bent to shape by bending in the direction of the larger crosssection dimension, Figs. 13, 14 (not shown).

Abstract: 1302181 Labelling apparatus NORPRINT Ltd 9 April 1970 [14 April 1969] 18930/69 Heading B8F  A hand-portable machine for printing and dispensing labels indexes supplied label strip for each machine operation by manuallyoperated means including a wheel which rotates a fraction of a revolution for each operation and has a respective plurality of projections adjacent each side of the periphery on the periphery for engagement with corresponding spaced articles in both side edges of at least a backing strip of the label strip, each projection being generally rectangular in section across the radius therethrough. The wheel 10 has a ratchet wheel 11 in a channel in the wheel periphery and either provides a positive drive to the strip 4 or rotates freely, providing a positive stop at the end of the index operation to accurately position the labels with respect to print wheels 14. In the former instance, as shown, a pawl 12, spring- loaded and pivoted on a movable arm 2, is moved forward one tooth length by the arm 2 moving towards a fixed arm 1, grips the tooth and, upon release of the cam 2, indexes the wheel. Either the wheel 10 drives the strip 4 at a position past the label-dispensing edge 15, or the wheel 10 is situated before the edge 15 and, through gearing, operates knurled feed rollers after edge 15, Fig. 8 (not shown). In the latter instance, Fig. 5 (not shown), the wheel 10 is upstream of the dispensing edge 15 and is driven by the backing strip 4 pulled by knurled feed rollers downstream of the edge 15 and operated by a rack or sector arm attached to the arm 2 and a ratchet mechanism. A stop abuts the ratchet wheel 11 during non-operation and movement of arm 2 towards arm 1 causes a projection to deflect the stop from the ratchet, allowing wheel rotation, but subsequent release of arm 2 causes the stop to engage the ratchet 11 to avoid over-travel of the backing strip 4. A wheel 14, mounted on arm 2, applies print to the labels during operation of arm 2.

Abstract: 1335022 Radar simulators SOLARTRON ELECTRONIC GROUP Ltd 27 Nov 1970 [1 Dec 1969] 58622/69 Heading H4D In Specification 1,335,023 there is computed a simulated aerial beamwidth # from which are formed upper and lower beam margins # u =#+(#/2) and  # l =#-(#/2) where 0 is the mean bearing of a simulated target. The differences (# u  - #) and (# - # l ) are formed and when both are positive a gating signal permits a range store output to pass. If # u  and # l  are either side of zero, at least one difference will always be negative and the range store output never passes. The present invention obviates this undesirability by generating a "straddle" signal when the zero/360 degrees position falls within the beamwidth margins, determining the polarity of the differences between the beamwidth margins and an assumed aerial position, generating an output signal dependent on those polarities and arranging that an output signal is generated only when the aerial position falls between the beamwidth margins and being altered in the presence of a straddle signal. In the embodiment beamwidth # is made proportional to (K+(1/R)) when R#(R max /8) and to K when R> (R max /8), where R is target range and K is a constant. Magnitudes # l , # u  and a straddle bit (="1" when # u  and # l  are on opposite sides of zero/360 degrees and otherwise "0") are stored serially in a shift register 13 and aerial bearing # from a counter 15 is stored in a store 16. The arrangement permits a pulse to be passed to a P.P.I. when: (a) If # u  and # l  do not straddle 360 degrees, (# u  - Q) is positive and (# l -#) is negative and (b) if # u  and # l  do straddle 360 degrees (# u  - #) and (# l -#) are both negative or both positive.

If temperature controller TC is demanding heat, conduits 12, 14, 16, 18 and 20 supply control fuel from upstream of the sensor valve through a normally open (third) valve D to the spark creation means, to cause spark actuation, and to a normally closed (second) valve C used to control valve D, and through a (fourth) normally open valve F to the time delay means. When the flame sensor valve opens, control fuel is supplied via conduits 32, 34, 36, 38, 40, 42 and 44 to open the main fuel valve, close valve F, reset the time delay means, and via 3-way (seventh) shuttle valve B to close valve D and open valve C. If the sensor valve closes due to flame failure, conduit 56 provides communication via conduits 40 and 42 to valves C and D to maintain them respectively open and closed during the time delay until re-ignition. Details are given of the bellows-type flame sensor valve and the control fuel pressure operated time delay valve means.
