Device 30 is formed by a terminated coaxial line 31, 32 encircling half the circumference of a short metal tube portion 33 of the otherwise glass envelope, four orthogonally arranged vanes projecting towards the axis of the tube 33 (Fig. 5, not shown) one pair from the lower wall of the tube, and the other through apertures in the upper half of the tube-from the inner conductor of the coaxial line, screw 36 permitting adjustment of the phase difference between the members of the upper pair of provide a rotating field. For transient phenomena, a short pulse electron beam is employed, and a photographic film placed in front of the phosphor screen. A prior art microwave cathode-ray tube is referred to (Fig. 1, not shown) in which the beam is first longitudinally velocity modulated in a gap (10) between two tubular electrodes (8, 9) by the wave under examination, and is subsequently given a rotating transverse velocity component by two orthogonal pairs of deflection plates (11, 12), to display the waveform as modulation about a circular path formed on a plane phosphor screen.

In a process for toughening glass in which glass at a temperature near to its softening point is quenched in a chilling liquid, preferably carbon tetrachloride or methanol, the surfaces of the glass are coated, prior to quenching, with a layer of a substance producing nucleation points on the glass surface, e.g. diatomaceous earth or zinc oxide, which engender nucleated boiling in the liquid, thus reducing the formation of a cohesive gaseous layer lying adjacent the glass surface. The coating is preferably applied in the form of a paste in toluene, methanol or water. The process can be applied to the process of the parent Specification.

Filed: 1970-11-23
Abstract: 1316502 Photographic film assemblies  POLAROID CORP 23 Nov 1970 [21 Nov 1969] 55625/70 Heading G2A A container holding an assembly of film units has a divider 46 separating the container into a forward section 42 housing the units, and a rear section 44, section 42 having an opening 66 through which a unit may be moved out of the  container, and another opening 68 being provided through which the unit may be moved back into section 44. As shown, the film units may be of the self-processing type in which a pod 36 of processing liquid is ruptured by passing between rollers 78, 80, forming part of the camera, the liquid then being spread between an image-recording sheet 32 and an image-transfer sheet 34. A framework 46 having cantilever spring members 56, 58 (see also Fig. 4 not shown) is located within rear section 44 and urges the divider forward against the film units in front section 42, so that the foremost one is located in the plane of the exposure window 16 of the camera. After exposure, the uppermost film unit is advanced to the left by electrically driven means (not shown) which engage the film and move it out of the container through the opening 66 into the bite of the rollers 78, 80. The camera includes a drawer 84, 86, 88 which can be moved outwardly from the initial position shown in Fig.5 to enclose the film unit as this is drawn towards the rollers. A flexible curtain 90 forms a light-tight enclosure as the drawer is drawn out. A spring clip 96 engages the leading edge of a film unit as it is drawn out, and displaces the trailing edge downwards. As the drawer is returned to its initial position, the film unit is pushed back into the container, this time through the lower opening 68, so that it enters into the space behind the divider. Thus as the succeeding film units are exposed and processed, they are all gradually transferred from the forward compartment 42 to the rear compartment 44, where they may be stored until removed from the camera. The exposure and processing system may be powered from a battery built into the divider, the battery also being connected by flexible conductive strips 108 to contacts 110 on the camera, and hence to electrically operated components of the camera. An opening (106) Figs. 2 and 3 (not shown) at the rear end of the camera enables a film unit to be manually withdrawn for inspection, and replaced if desired.

Headings H2F and H2K. In a H.V.D.C. transmission system the conductors connecting a converter sub-station to earth electrodes outside the sub-station are continuously monitored and faulty condition thereof is sensed as a current change and used to operate a warning indicator and/or disconnect the converter from the transmission system. The connections include two insulated conductors 1 connected to a common earth electrode and the opposite ends respectively of a secondary winding 4 of an auxiliary transformer 2 energized from an L.T. mains source. A centre tap of the secondary is connected to an H.V.D.C. transmission line 6 and to a neutral point of the converter station. The secondary continuously circulates a current of about 10 amps. through the closed circuit formed by the conductors, and is designed to carry a direct current greater than half the rated current of the transmission line. In the case of a two-pole transmission line, if one of the conductors 1 should break then the current in primary 3 will change causing operation of a relay warning device 8. In the case of a single pole and earth return transmission line, if one of the conductors 1 should break, then output currents of D.C. transformers 9 will no longer balance one another so that a relay 11 operates to disconnect the converter station from the transmission line.

Abstract: 1281390 Error detection POST OFFICE 28 Oct 1970 [10 Dec 1969] 60314/69 Heading H4P In a system for testing a digital data transmission system a serial test pattern is transmitted in which each bit is generated as a function of two or more preceding bits, each spaced from the bit by a particular spacing, and a receiver of the pattern compares each bit with the corresponding two or more preceding bits to ascertain if the function is still satisfied, lack of correlation generating an error signal. The test pattern is generated by a shift register having the output of two stages, which may or may not be adjacent, modulo-2 added and fed back to the input of the register. At the receiver the arriving pattern is put in a register and each bit on entering is compared with the output of two stages ahead, spaced by the appropriate amounts. Since each erroneous bit, unless adjacent to other erroneous bits, gives rise to three error conditions on its passage through the receiver register, the count of error signals is divided by three or alternatively a modulo-2 adder is placed after the first stage of the receiver register to correct the erroneous bits.
