Title: Process of treating artificial silk and product thereof
IPC: C08J5/06
Filed: 1933-11-15
Abstract: Rubber is bonded to artificial silk by treating the artificial silk with an aqueous protein-latex composition, drying, applying a rubber composition and vulcanizing.  The artificial silk may be in the form of a sliver, roving, thread, strand, yarn or cord or a loosely matted, knitted or woven fabric and may be made from viscose, cellulose nitrate or acetate or cuprammonium cellulose. The protein is preferably casein, but glue, albumin, gelatin, haemoglobin and blood may be used.  A casin latex composition may be made by grinding casein in water, adding dilute alkali, e.g. aqueous ammonia, regrinding and mixing with rubber latex.  Ammonia may be replaced by lime, sodium fluoride, sodium carbonate, sodium or potassium hydroxides, borax, or tri-sodium phosphate. Age-resisters for casein such as hydroquinone, sodium chlorophenylphenate or sodium orthophenylphenate, and insolubilizing agents may also be added. After treatment with the protein-latex composition the artificial silk is first dried at room temperature to avoid blistering, after which further drying may be done at higher temperature.  The invention may be used in making automobile tyres, rubber hose, fan belting of V- or flat-section, universal couplings, mats and padding. Specification 347,735 is referred to.  The Specification as open to inspection under Sect. 91 comprises also the use of fibrous materials such as cotton, silk, flax, wool, linen, ramic, hemp, wood fibre and pineapple fibre.  This subject-matter does not appear in the Specification as accepted.

Title: Sheets for cabinet and joiners' work and a process for their manufacture
IPC: B32B27/00
Filed: 1936-11-20
Abstract: 480,129. Composite wood boards. PFOHL, F. Nov. 20, 1936, No. 31876. Convention date, Nov. 28, 1935. [Class 145 (ii)] A composite wood sheet is formed from three layers of wood strips, those in the inner layer being coarser than those in the outer layers, the strips being moistened with adhesive and formed into a pile in which they lie crisscross on one another but substantially parallel to the surface of the sheet to be formed, and the pile being then compressed to form the sheet. The adhesive may be size, casein, albumin, artificial resin glues, or the like, and excess may be removed from the strips prior to pressing, for example by centrifugal action. The strips are dropped into a casing in the press and allowed to remain in the criss-cross positions in which they fall, the height of the stacked layer being about six times the thickness of the sheet desired. The pile is then compressed, at atmospheric or higher temperatures according to the adhesive employed. The outer layers may be formed from strips 50 mm. long, 4 mm. wide, and 0À5 mm. thick, and the inner layer from strips 100 mm. long, 6 mm. wide, and 1 mm. thick. If a very smooth surface is desired, the sheet may be faced with a coating of very thin strips, compressed together with the other layers, and may then without further treatment be veneered.

Title: Improvements relating to impulse generators
IPC: H03K3/537
Filed: 1949-12-13
Abstract: 659,388. Electricity supply, condenser arrangements. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Dec. 13, 1949, No. 31993. Convention date, Dec. 13, 1948. [Class 38 (iv)] [Also in Group XL (c)] In a high voltage pulse generator of the Marx type in which a number of capacitors are charged in parallel from a charging source and are subsequently discharged in series, two spark-gaps are connected in series between the connection to the charging source and earth, across each of the gaps a resistor is connected and the discharge is initiated by applying a source of potential to break down one of the gaps which causes the other gap to break down and thus completes the connection of the charging terminal with earth. The Figure shows a Marx generator in which capacitors 2, 3, 4 are charged in parallel from the charging source 12 and are discharged by spark gaps 7, 8 in series into a load. If it is assumed that source 12 has a voltage of, say, - v volts, then initially plate 33 of capacitor 28 will be at earth potential and plate 34 which is connected to the mid-point of potentiometer 2 will be at - V/2 volts. To initiate the discharge of the generator the tripping voltage source 27 is given a voltage of V - - volts which is transferred to plate 33, 2 plate 34 thus attains a voltage of - V so that the potential difference across spark-gap 31 is zero. The potential across gap 32 is V, so that this gap which is arranged to fire with a voltage V between - and V now fires and electrode 26 2 falls to earth potential. Terminal 10 which was initially at - V volts is thus raised to earth potential, the plate 14 of capacitor 2 is raised to +V volts and the potential 2V across sparkgap 7 fires this gap so that plate 17 of capacitor 3 has its potential changed from - V to +V volts. The plate 19 is raised to + 2V volts and gap 8 fires, and the capacitors 2, 3, 4 are thus discharged in series into the load. If the potential of source 27 is of a voltage +V/2 volts, spark-gap 31 will break down first. In a modification, Fig. 2 (not shown), two auxiliary spark-gaps are connected in series between the tripping voltage source and the centre tap on potentiometer 2; the capacitor 33 being dispensed with.

Title: Improvements in methods of and apparatus for boring through strata
IPC: E21B7/00
Filed: 1919-12-23
Abstract: 139,459. Delecourt, J. Feb. 26, 1919, [Convention date]. Bore-hole apparatus and processes.-In apparatus employing free fall mechanism operated by an oscillating beam and released when the beam strikes a stop at the end of its upward stroke, the free-fall mechanism is so modified that the apparatus may also serve for rotary boring and the boring-rods, their connexions, and the freefall mechanism are hollow so that the apparatus may be used for either wet or dry boring. Ir. the apparatus shown, the beam 1 supports the boring rods 12 through the medium of a pivoted hollow screw 11 and a nut 22 supporting a clamp 27 fixed to the rods. In percussive boring, the beam 1 is oscillated by a single-acting engine 4, the stroke being limited bv beams 9, 10 in a frame 8; the feed is effected by rotating the nut by handles 24 and the rods are turned by means of handles 30. The blows on the beam 10 may be cushioned by a stirrup 53, Fig. 8, mounted on springs 51. A clamp 59, adjustably carried by the boring rods, contacts with the beam 1 at the end of a feed and takes the weight of the rods during re-adjustment of the feed-nut. The freefall member 33, Fig. 5, carrying the boring tool, is sli.lably connected to the boring rods by keys 44 and is raised and released by two oppositelyplaced catches 40 controlled by external tappets 43; the member 33 carries a hollow piston 37 sliding in a cylinder 38 to provide a continuous water passage. The catches 40 may be removed to connect the free-fall apparatus into a simple sliding joint. When the apparatus is tn be used for rotary boring, the handles 30 are removed from the boring-rods, a ball bearing is placed between the nut 22 and clamp 27, counterbalance weights are placed on the beam 1 and lugs are arranged to reduce the range of movement of the beam; the drill rods are rotated by engines on a platform 54 and movement of the beam 1 operates a bell to indicate that feeding of the rods is necessary. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the use of adjustable distance pieces 58 against which the beam may rest; this subject-matter does not appear in the Specification as accepted.

Abstract: 1430008 Electrographic developing ING C OLIVETTI & C SpA 6 July 1973 [13 July 1972]  32287/73 Heading G2H A developer unit 1, of the kind in which a magnetic brush 12a is formed on the outer surface of a rotatable cylinder 6 of non-magnetic material enclosing a non-rotating magnet 7, is reciprocable towards and from the image surface 30a of a  photo-conductive drum 30 in syncronism with the rotation of the drum 30, and includes means for adjusting the orientation of the magnet 7 about the axis of the cylinder 6 between first and second positions in which the arcuate extent of the part of the brush which is effective to transfer developer particles to the electrostatic image is different, and a third accessary position. The magnet 7, together with its associated flux diverting shunt 7a and pole shoe 7b, is normally positioned as shown in full lines but may be rotated about 15 degrees clockwise to the position indicated by broken lines to increase the length of arc over which the magnetic brush 12a wipes the drum 30 when a more intense developed image is required. The developer is replenished with concentrated developer (i.e. 50% toner 50% carrier) once in every eight operative cycles of the machine by a supply cylinder 16 of non-magnetic material which is rotated stepwise together with a magnet 17 housed within it. The concentrated developer is picked up by the cylinder 16 in two zones C, D, is levelled by a dosing flap 22 and scraped off into a developing container 3 of the unit 1 by a doctor blade 20. To empty spent developer from the container 3, a trap 4 is opened and the magnet 7 is rotated through 90 degrees to its accessory position where its flux diverting shunt 7a overlies the trap 4 and weakens the magnetic field in this region allowing the developer 12 to drop out. Rotation of the cylinder 6 by hand completes the discharge of the developer.

Abstract: 1431430 Cooling vapour by direct contact with a liquid BABCOCK & WILCOX Ltd 25 July 1974 [25 July 1973] 32882/74 Heading F4K A vapour stream is attemperated by a liquid stream as both streams flow upwardly through a sleeve 8. As shown the sleeve 8 is contained in a housing 3. The sleeve at its upper end portion 10 has perforations 12 therein and is of reduced diameter so as to form with the housing 3 an expansion chamber. Steam from a primary superheater 1 enters the housing at 4 and, together with water spray from upwardly discharging nozzles 7 passes upwardly within the sleeve 8. The smaller water droplets flash into steam as they pass with the main flow of steam through the perforations 12 into the expansion chamber. The larger droplets continue upwardly and are trapped by a deflection plate 13 from which they fall back into the upwardly flowing fluid stream in the sleeve. Steam passes out of the attemperator into a secondary superheater 2 at the outlet of which is a temperature-responsive device 16. Water spray from the nozzles 7 is at a rate depending upon the steam temperature sensed by the device 16 which actuates a control device 17 for the spray-water regulating valve 6.
