Abstract: 1299005 Cassette-loading machines M J ROOS (KAHLE ENG CO) 16 April 1970 18258/70 Headings G2A and G2E  A machine for loading film into the type of cassette in which a supply spool and a take-up spool are mounted coaxially on either side of a central partition comprises a large supply roll 21 of the film which is fed via footage counter 30 to a spooling and loading assembly 34. Here it is wound on to an arbor, the trailing edge cut and staked to a take-up spool 12, the spool 12 and the arbor then being inserted into the cassette and the arbor drawn away. In winding the film on to the arbor (130) Figs.13-15 (not shown) the end of the film is attached thereto by the operator, who then energizes the motor. After the predetermined number of turns have been wound on to the arbor the counter 30 causes the motor to be switched off. A punching assembly 40 is now operated, which punches out a tongue 41 in the trailing (now leading) end 42 of the film on the arbor. The operator now threads end 42 into a groove 152 in the core of a plastic take-up spool 12 held in a staking tool 144, the tongue 41 being positioned with its shoulder portions 145 against guide pins 146 in the upper jaw member 143 of the staking tool, see also Fig.22. The staking tool has a finger 150 having opposite edges 153, and a guide rod 151. On operating the tool, the edges 153 of finger 150 engage the spool walls and crimp the material thereof round the film tongue, locking it into the groove 152, Fig.23 (not shown). The tool 144 and upper jaw are then opened, Fig.18, so releasing the spool. The cassette body 2 is positioned against a fixed guide (156) Fig.17 (not shown) and slipped over the film 6 wound on the arbor, the arbor itself then being drawn away. The cassette is now placed in a frame guide 160, and the film threading completed by placing it across a pressure pad 10 and threading it into the cartridge body on the opposite side of partition 5 from the film roll 6, and then partially winding the lead 42 round the spool 12 as the spool is fitted over the spool mounting shaft 161 in the cassette body 2. Finally, the cover 3 is fitted over the cassette. The word "exposed" may be printed on to the film by means mounted with the punching assembly 40 so that it becomes visible at a window 14 in the cassette at the appropriate time.

Title: Improvements in radio navigation systems
Inventor: MCMULLIN TERENCE ALEXANDER
IPC: G01S1/02
Filed: 1954-06-28
Abstract: 766,076. Radio navigation. MURPHY RADIO, Ltd. June 28, 1955 [June 28, 1954] No. 18876/54. Class 40(7) The invention relates to receiving apparatus for a radio beacon which in response to interrogating pulses radiates pulses upon two slightly divergent beams. a succession of pulses of short duration (dots) on one beam being radiated alternately with a succession of longer pulses (dashes) on the other. The receiving apparatus is of the type in which the received signals are gated by a stroke pulse which is automatically maintained in synchronism with the wanted pulses and overlapping them to a small extent. Thus if the long and short received beacon pulses are as shown at b and a respectively (Fig. 2A) the locking stroke will be positioned by known means to occur as indicated in Fig. 2B. In the embodiment described the stroke pulses are lengthened by about a dot width to give pulses as shown at 2C which are fed to gate valve 3, to the control grid of which are applied the received signals. The output of this gate is fed over transformer 4, 5 to two diodes 6 and 7. The first of these feeds the automatic gain control circuit whilst the second feeds one of two Miller integrators 8, 9 between the cathodes of which is connected the indicating meter 10. A further stroke pulse 2D, beginning about a dot pulse duration after the end of stroke 2B, gates a further signal input applied through capacitance 14 to valve 11. The output of this valve, which occurs only when long pulses are received, is used in valve 12 to gate a signal input delayed as indicated at 2E so that long pulses only are fed to diodes 21 and 22. Rectifier 21 is connected to the same integrator to which the rectified signals from diode 7 are applied so as to, in effect, subtract the impulses produced by the dashes from those produced by the dots and the dashes and so apply signals to grid of valve 8 proportional to the amplitude of the dot beacon pulses only. Diode 22 applies similar signals proportional in amplitude to the dash beacon pulses to the grid of valve 9. The grids of both integrators are connected through condenser-shunted resistances to a source of negative bias 27 so that they would conduct only while the effect of the applied signal pulses persists except for the action of condensers 28 and 29 which maintains the anode voltages sufficiently to bridge the gaps between the signal pulses. The meter interprets the information received to give left or right turn indications. Specifications 690,477 and 690,480 are referred to.

Patent GB-486366-A (GB)
Title: Improvements in and relating to processes for the production of nucleosides
IPC: C07H1/00
Filed: 1937-07-08
Abstract: Guanosine and adenosine are produced by causing emulsion to act on nucleic acids at a pH value of 4-5,5 and preferably at a slightly elevated temperature, e.g. 30-40 DEG  C., crystallizing and separating the guanosine formed, precipitating the adenosine in the form of its picrate, and decomposing the picrate with a basic substance, preferably one forming a difficultly soluble picrate, e.g. potash or ammonia.  The action of the emulsion should be continued preferably until the splitting off of phosphoric acid ceases, this occurring after about 8-14 or more days.  The nucleic acids may be preliminarily degraded before treatment with emulsin by the action of alkali, e.g. a liquor having a 2-5 per cent alkali concentration. After heating on a water bath for a few hours, the hydrogen ion concentration is brought to the necessary value, e.g. by the addition of acetic acid, before the addition of emulsin.  When an aqueous solution of picric acid is p  used, it is generally necessary to evaporate the mixture in vacuum before the addition of the picric acid.  The phosphoric acid can be removed by treatment with baryta water and excess barium removed by sulphuric acid.  Evaporation can be entirely or in part dispensed with if solid picric acid is added to the solution freed from guanosine and albumen, but which may contain some sulphuric acid.  In an example, a mixture of yeast nucleic acid and caustic solution is heated on a water bath for two hours. When the solution has cooled to 40 DEG  C., acetic acid solution at 40 DEG  C. and then an emulsion solution and a few drops of toluene are added.  The solution is placed in an incubator at 37 DEG  C. and is shaken daily.  After 12-14 days, the solution is placed in an ice chest, and the guanosine formed is filtered and washed with water, alcohol and ether.  The filtrate is boiled and cooled, and albumen then filtered off.  Phosphoric acid is removed as above. The solution is evaporated somewhat, and heated to 50 DEG  C., dry picric acid being then stirred in.  After standing in an ice chest, adenosine picrate is filtered off, and washed with water, alcohol and ether.  The picrate is crushed, treated in an Erlenmerger flask with water, and heated to 55 DEG  C.  Concentrated potash solution is then added, and after standing in ice water, potassium picrate is filtered off.  The filtrate is seeded with adenosine, and after standing in an ice chest, the paste is filtered off, washed with water and then with acetone.  The adenosine may be recrystallized from water.  A 25 per cent ammonia solution may be used in place of the potash solution.  Cytidine and uridine can be obtained from the filtrate obtained after precipitation of the adenosine with picric acid.  A statement of the prior art refers to the action on yeast nucleic acid of juices expressed from spinach, or Cortinellus edodes or nucleotidases from liver, or intestinal mucus. The adenosine is isolated in the form of its picrate, which is decomposed by sulphuric acid.  The yield is very small.
