Title: Partition-wall elements and partition-walls formed of such elements
IPC: E04C2/38
Filed: 1970-09-24
Abstract: 1323760 Wall panel TRAMEX SA 24 Sept 1970 [25 Sept 1969] 45677/70 Heading B5N [Also in Division El]  A panel for use in a partition construction comprises a rigid core formed, e.g. from a conglomerate of plaster reinforced with straw, which has at least one facing of compacted, polished plaster. The core may also be of reinforced expanded polystyrene. The panel has one or more grooves 5-7 along at least one peripheral face, and elongate cavities 8 extending into the core from the grooves, which may be of semic-circular or V-section. The plaster/ straw mixture is fed on to a conveyer 17, e.g. in a compressed form, transported to a die 20 which may further compress it, and when the grooves and cavities are formed, and thereafter the panel is cut to length, and faced, on a smooth-surfaced member 21. A second die treatment is then applied to achieve the correct thickness. The facings may have a "cut", "smooth" or "slured" finish. Finish papers may also be applied, the face or faces to be treated then being formed with a recess at each edge.

Abstract: 1446576 Calculator BIOMATE (UK) Ltd 1 Oct 1974 [2 Oct 1973] 45990/73 Heading G4B An indicating device houses a plurality of rotatable discs each bearing a curve, the radial variation of which is representative respectively of one of a set of cyclically varying characteristics, e.g. human "Biorhythmic" states; the discs, together with a time elapse disc co-operating with manual drive means to be rotatable through an angle representative of a time interval. Discs 3-5 each carrying a curve representing a cyclically varying human "Biorhythmic" state and having angularly spaced numbers (not shown) are mounted in housing 1 to be simultaneously rotatable with calendar disc 2 by the gear engagement of a single slidably detachable thumbwheel 9. In use the thumbwheel drive is disengageable, allowing a user to manually align his birthdate on calendar disc 2 via datum 14 on cursor 13. Discs 3-5 are similarly set to a number prescribed for each according to a table provided; the thumbwheel then being re-engaged to allow for manual rotation of the discs to any selected calendar date whereat the intersection of a curve and the datum qualitatively indicates the user's "Biorhythmie" state with reference to a "zero" circle inscribed upon each disc 3-5. Gear drive between thumbscrew and discs may be replaced by friction drive, and a separate datum may be provided for each disc.

Filed: 1969-09-18
Abstract: 1,273,044. Parachutes. P. M. LEMOIGNE. 18 Sept., 1969 [4 Oct., 1968], No. 46037/69. Heading B7G. A parachute for gliding with a horizontal component of motion has cutouts 10, 11 extending radially over a distance smaller than half the distance between the periphery and apex of the canopy to prevent turbulence inside the canopy and so provide improved lift and manoeuvring characteristics and has nozzles 2, 4, 15, 20 to allow air to escape in only one direction and provide thrust for motion in a horizontal plane. The leading edge cutout 10 prevents the canopy assuming a concave shape, which is detrimental to the efficiency of the canopy by causing turbulent airflow therein. Cutout 11 favours a throughflow of air, hence increasing the horizontal component of motion, and also provides a flowpath for air deflected by a lowering of the canopy when a turning manoeuvre is executed, for example by pulling rigging lines 28, 30, 32, connected to a control handle, in order to turn left. The substantially square panels, which together comprise most of the canopy, may be of low or no porosity close to the periphery and of greater porosity at the centre of the canopy. The canopy may have slots in the panels 16 of the nozzles 15 to reduce the shock of parachute opening and which are normally held closed by ties. Anti-shock slots 56 are also provided. Detail modifications are described.

Title: Brazing preform and brazed joints
Inventor: STENERSON RANDOLPH N
IPC: B23K1/20
Filed: 1967-10-09
Abstract: 1,202,227. Brazing preform. CARRIER CORP. 9 Oct., 1967, No. 46126/67. Heading C1M. [Also in Divisions B3 and C7] An annular brazing preform comprises a finely divided brazing metal suspended in a fused glass matrix. During brazing the brazing metal melts, coalesces and flows within the glass matrix between the members to be joined and the glass forms a protective coating over the outside of the joint. The glass coating preferably has a lower coefficient of expansion than the members so that it breaks and flakes off the joint leaving little or no glass coating after cooling of the joint. In making the preform the constituents of a brazing alloy, e.g. 50-25% Ni; 42% Fe ; 4.5% Si ; 3.25% B, are heated in a vessel, then poured into a jet of water which produces solidification in small spherical particles. A glass composition is made by mixing 28À78% dehydrated borax (Na 2 B 4 O 7 ) with 40.11% silica (SiO 2 ) and 31.11% whitening (CaO) and smelting to form a glass containing 10.3% sodium oxide (Na 2 O); 20À1% calcium oxide (CaO) ; 23À1% boron oxide (B 2 O 3 ) and 46À5% silicon dioxide (SiO 2 ). Up to 10% of the sodium oxide may be replaced by potassium oxide and/or lithium oxide and the calcium oxide by barium oxide or strontium oxide. After smelting the molten glass is poured into cold water to produce a coarse frit which is milled and sieved through a 400 mesh screen. A binder of 10% carnauba wax and 10% of paraffin dissolved in 80% trichloroethylene is prepared. 77À7% of the brazing alloy powder, 19À4% of the glass frit and 2À9% of the binder are mixed, heated to vaporize the solvent, then passed through sieves and pressed at 100,000 p.s.i. in a die to the preform shape. The body is then sintered to fuse the glass particles and remove the binder at 1350-1400‹ F. for about 1 minute and produce the finished preform. An alloy of 95% Zn, 5% Al, may also be used.

Abstract: 1,152,499. Winding layouts for dynamoelectric machines. NATIONAL RESEARCH DEVELOPMENT CORP. 6, Oct., 1967 [18 Oct., 1966], No. 46604/66. Heading H2A. In a three-phase, alternating current, polechanging: winding employing pole-amplitude modulation, the harmonics are reduced and winding factors improved by the use in at least two of the phases of non-symmetrical coil groupings similar to that described in Specification 926,101 as a means of applying poleamplitude modulation to machines having a pole-number which isa multiple of three. In that Specification, two of the phases have; had the same numerical coil-groupings, but disposed in opposite sequences round the machine. This was referred to as " skew-symmetry," and the winding according to the present invention is " totally-skewed" in having different and/or asymmetriccoil-groupings for two- or, more usually, all three phases. The balance between the phases may be improved by combining several different modulated windings in the same maehine as described in Specification 1,133,062.

Abstract: 1,063,509. Twisting polypropylene film. SOC. NORMANDE DE MATIERES PLASTIQUES. Nov. 3, 1965 [Nov. 4, 1964], No. 46636/65. Heading BSB. [Also in Division D1] Binding is made by twisting and drawing a film of polypropylene having reduced viscosity 1À1-5À0. The twisting may be performed before drawing, or between two drawing steps. The draw ratio may be 0À9xe<SP>0À4</SP>, where e is the film thickness in microns. The drawing may be performed at 80‹-160‹ C. with draw ratio 2À5-12; if two drawing steps are performed, the first may be at 140‹-160‹ at 70% of the total draw ratio, and the second at 95‹- 140‹ C. The twist should be 1/#m turns/metre, where m is wt. in g/metre. The preferred thickness of the film is 0À015-0À30 mm.; the width may be 10-250 mm. The binding may then be flexibilized by (1) untwisting and retwisting; (2) rolling; (3) rolling and twisting, combined with untwisting and retwisting; or (4) rolling and twisting. In method 1 a string 1 of the strapping passes from braked rollers 2, 4, 5 through ring 6 to a revolving platform comprising free rotatable pulleys 7 and 8 which rotate rapidly about spindle 9, serving to untwist the string coming from roller 4 and to retwist that proceeding to driven roller 12. In method 2, the string is drawn through a train of meshing gear-wheels (Fig. 2, not shown). In method 3 the string passes between two endless bands oppositely inclined to the path of the string, forming an X (Fig. 3, not shown). The bands may be made of a number of close parallel rollers (Fig. 4, not shown) which may be covered with a flexible non-slip belt. In method 4, the apparatus of method 1 is modified by replacement of the revolving platform by a sequence of parallel rollers disposed alternately in two mutually perpendicular planes, the line of intersection of the planes being the direction of movement of the string (Fig. 5, not shown). The nip decreases along the train.
