Title: Improvements in or relating to pressure suits or helmets
IPC: A62B17/00
Filed: 1957-06-21
Abstract: 846,297. Pressure suits and helmets. TAYLOR, E. H., and BAXTER, WOODHOUSE & TAYLOR Ltd. Sept. 22, 1958 [June 21, 1957], No. 19657/57. Classes 63 and 141 Relates to a pressure suit or helmet as used by aviators and to connections between the limbs and body of the suit or between the helmet and shoulder part of the suit so as to facilitate bending and turning movements between the adjacent parts. According to the invention a hoop-like member is secured to each part and a plurality of linking means connect and are movable on the members to allow relative rotation thereof, the linking means allowing movement of the members towards one another and the pressure bladder of the suit at the connection being longer than is necessary to extend between the parts so as to allow for relative rotation between the adjacent portions of the suit bladder. In one embodiment described the pressure bladder consists of a head part 1, Figs. 1, 4 leading to a neck part 2 which in turn leads to a shoulder part 3. This part 3 is sealed against the upper part of the suit by a seal bladder 4. A visor 6, as described in Specification 815,498 is pivotally mounted on the helmet shell 5 by hinges 7 for movement into and out of sealing contact with an opening in the head part 1. The pressure bladder is formed of extensible rubber and is contained within an inextensible cloth cover 8 in two parts 9, 10, Figs. 3, 4, spaced apart at the neck part 2 and joined by a connection 11, the neck part 2 being made longer than necessary so that it is gathered at the neck opposite the connection 11. The cover 8 is provided with a sliding clasp fastener 13 extending down the back of the helmet. The connection 11 includes hoop-like members in the form of open loops of wire 15, 16 attached by eyelets 17 to the opposed edges of parts 9, 10, the ends of the loops 15, 16 being secured by metal rings 18 to the tapes of the fastener 13. Threaded on the loops 15, 16 are short chains 19 which by sliding on the loops allow relative rotation of the loops. Two overlapping bands 20, 21 of material having a low coefficient of friction are disposed between the chains 19 and the neck part 2 of the pressure bladder. In other embodiments described the head and shoulder parts of the pressure bladder are made from a rubber and cloth laminate which is substantially inextensible, the neck part only being made of extensible rubber and no cover 8 is provided. The connection 11 comprises a plurality of runners 29, Figs. 8, 11 (not shown), which link a wire loop 24 with a rail 25, each runner engaging a track in the rail 25 similar to the track provided in a curtain rail. The connection 11 may be arranged within the pressure bladder instead of outside it, the extensible neck part 2 of the bladder having moulded therein restrainer-cords 34, Figs. 10, 11 (not shown), which control the expansion of the neck part.

Title: Improvements in or relating to the refining of cyanogen chloride
IPC: C01C3/00
Filed: 1945-08-02
Abstract: Cyanogen chloride vapours are purified by passing them first through a bed of calcium carbonate in the presence of water to remove hydrogen chloride and then over a non-alkaline dessicant to remove water, the thus purified vapours being condensed and recovered.  If the vapours contain chlorine, the treatment with the dessicant is followed by contact with an adsorbent for free chlorine such as activated coconut or wood charcoal.  The adsorbent is preferably cooled, say to 0+5 DEG  C.  Activated charcoal initially adsorbs considerable cyanogen chloride, but this is subsequently displaced by the chlorine in the dry oncoming vapours.  Specified dessicants are anhydrous calcium chloride, calcium sulphate, magnesium sulphate, sodium sulphate, copper sulphate or silica gel.

Title: Method of aligning a surface of a body provided with a fiducial  mark thereon with an image in electrons
IPC: G01B11/27
Filed: 1974-05-09
Abstract: 1467079 Cathode-ray tubes MULLARD Ltd 9 May 1974 20447/74 Heading H1D [Also in Division G1] In the alignment of a surface of a body provided with markings, with an image in electrons, the markings are in the form of two patterns having different spatial frequencies. The invention is applied to integrated circuit manufacture. In Fig. 2, a semi-conductor wafer 5 is supported by metal plate 7 and is coated with electron resist 6. It is desired to expose the resist to an image in electrons, so that by subsequent processing a contact mask is left on the water surface having the design of the electron image. To expose the resist to such an image, the wafer is mounted, as shown, on one side of vacuum enclosure 14, at 20 kV. positive potential with respect to a photocathode 8, supported on a quartz plate 9 with an intermediate titanium layer. By illuminating a mask 12, corresponding to the desired electron image, with ultra-violet radiation from lamp 11, the photocathode emits the desired image. This now requires alignment with the pattern of markings on the wafer 5 surface before the actual exposure of the resist can take place. The pattern of markings is formed of tantalum, which emits X-rays on irradiation by the electron beam and it is designed as shown in Fig. 1 and is repeated in the top and bottom halves of the wafer, for viewing via apertures in support 7 by semi-conductor detectors 15 and 16 which are sensitive to X-rays omitted from the pattern of markings. In the alignment operation, detector 15 is used alone, to perform alignment in two orthogonal directions. By means of two sets of deflection coils (only one set 21, 22 shown) the electron image, which includes portions corresponding to the pattern of marks on the wafer 5, is stepped backwards and forwards with respect to the latter, on two orthogonal directions. This is accomplished by generators 19, 20, producing different frequency shaped A.C. waveforms which also feed phase-sensitive detectors monitoring detector 15 output. In a first, coarse alignment, stepping is at integral multiples of the pitch of the fine patterns 2, 4 (and less than the pitch of patterns 1 and 3). Approximate alignment produces zero outputs for the component of the detector output representing patterns 2 and 4, but misalignment of patterns 1, 3 with the electron image produce a signal which is used to produce a correcting current for the coils or causing mask 12 and/or wafer 5 to be moved, e.g. by a stepping motor, to reduce the error. Once coarse alignment has been effected, fine alignment, is carried out by stepping the image by an amount less than the pitch of fine patterns 2, 4. Rotational alignment is carried out on a similar coarse and fine basis by switching detector 15 out of, and detector 16 into, circuit. If a third phasesensitive detector connected to detector 16 is provided, the detector switch is omitted, and orthogonal and rotational alignments may take place simultaneously.

Abstract: 148,557. K÷rting & Mathiesen Akt.-Ges. June 9, 1915, [Convention date]- No Patent granted (Sealing fee not paid). Oscillatory motor meters.-A coil 2 in shunt with a resistance 1 in the main circuit oscillates in the field of a shunt magnet 4, the polarity of which is reversed at the end of each oscillation. The spindle 6, to which the coil 2 is attached, carries an arm 9 which, at the end of each oscillation, strikes against contacts 10, 11 alternately, thereby energizing the corresponding coil 12, 13 of a relay, the armature 14 of which is polarized by stray field from the brake magnet 8. This relay actuates the counting-mechanism and also a commutator 16 which reverses the exciting-current of the shunt magnet 4. The oscillating coil 2 surrounds a fixed iron core 5 cut away at 20 to permit the spindle 6 to pass through. The pole-pieces 3 of the shunt magnet 4 are flat so that the oscillating system can be removed without disturbing the field system. The inoperative parts of the brake disk 7 are cut away to reduce weight.
