Title: Improved Moulding Materials
Inventor: SCHUELER GEORGE BERTHOLD EDWAR
IPC: B29C67/24
Filed: 1965-07-12
Abstract: 1,156,205. Coating with preformed sheets. REDLAND BRICKS Ltd. 30 June, 1966 [12 July, 1965; 5 April, 1966], Nos. 29470/65 and 15160/66. Heading B6G. [Also in Divisions B5, C3 and D1] A moulding material comprises a homogeneous mixture containing more than 50% wt. finely divided inorganic material, fibrous material and less than 30% wt. of a synthetic resin, in the form of a compacted sheet in which all of the fibres lie in planes parallel to the major surfaces of the sheet. The inorganic material can be sand, granite dust, limestone dust or quartz. Flame-retarding or fire-extinguishing fillers, and pigments can be included in the mixture. The fibrous material can be fibres 0À1-1À5 inch long formed of glass, asbestos, sisal and be used in the amount of 2-15% of the total mixture. The resin can be a polyester, epoxy or acrylic resin and may also contain benzoyl peroxide, aluminium stearate, zinc stearate or t-butyl perbenzoate. The cured moulding can be rigid or have a slight flexibility. The moulding material is made by mixing the constituents and subjecting the mixture to compaction so as to align the fibres. The mixture can be compacted by nip rollers, oscillating pressure plates, extrusion, steel balls or grooved wheels. Before compacting the mixture may be vigorously combed to produce a fluffy mass, by feeding the mixture from a hopper (2) through rollers (3, 4) on to a spiked rotor (5) which tears at the mixture and projects it toward a pair of compacting rollers (7, 8) see the Fig. (not shown). The moulding material can be moulded at temperatures of 60-150‹ C. and pressures up to 250 p.s.i. The moulding material can be decorated with patterns. The moulding can be hollow and so-formed by wrapping the compacted sheet around a removable core and cured. Hollow sections can be filled with stone rubble, liquid cement or fire-resistant materials. The moulding can contain wire mesh, metal grids or conduits. The moulded sheet can be wrapped around a core, e.g. a foamed polyurethane slab, polystyrene foam, woodwool cement slab or compressed straw slab, the sheet shrinking on curing. Pipes may be formed by wrapping the sheet around a removable core and curing under heat and pressure. Two or more of the compacted sheets can be combined before curing, e.g. by cold or hot (90‹ C.) pressing for 5 mins. The layers can be of different composition or colour so as to form, for example, window frames or tubes having different finishes on the inside and outside of the frame or tube. A metal grid reinforcing layer, or a layer of low cost material, can be incorporated between two sheets. Texturing agents, e.g. pigments and pebbles, can be incorporated in the surfaces before curing. Sheets can be joined by edge butting, rolling then curing, e.g. to form a zebra crossing.

Title: Improvements in or relating to methods of toughening glass in sheet form
IPC: C03B27/052
Filed: 1965-04-09
Abstract: 1,133,615. Toughening glass articles. PILKINGTON BROS Ltd. 23 Feb., 1966 [9 April, 1965], No. 15285/65. Heading C1M. In a method of toughening a glass article (especially a flat or bent glass sheet) in which the glass is heated to a temperature near its softening point and a gaseous chilling medium is then directed at its surfaces, the gaseous chilling medium is initially directed at the glass surfaces at a controlled rate until a maximum temperature difference between the core and the surfaces of the article is established, and the gaseous chilling medium is then subsequently directed at the surfaces of the glass article at a higher rate substantially to maintain the said maximum temperature difference between the core and the glass surfaces until both the core and the surfaces of the glass have cooled to a temperature which is below the strain point of the glass. The glass sheet may either be suspended from tongs and moved vertically through a heating zone, a bending zone wherein it is shaped between complementary shaping members, and two cooling zones, or may be conveyed horizontally on rollers through heating and cooling zones. In the first cooling zone the sheet is subjected to air blasts at a pressure of 1 i.w.g., this being increased in the second zone to 10 p.s.i. The residence time in the first zone is 4 seconds for <SP>3</SP>/ 16  inch glass sheet, 6 seconds for 1/ 4  inch and 10 seconds for <SP>3</SP>/ 8  inch, with say 20 seconds in the second zone. The change from low to high pressure cooling may be either sudden or gradual. The method can also be applied to insulators.

Title: Stretch measuring device
IPC: B21D3/12
Filed: 1959-05-05
Abstract: 871,009. Strain gauges. SUTTON ENGINEERING CO. May 5, 1959 [May 15, 1958], No. 15336/59. Class 106 (2). [Also in Groups XXII and XXIX] A device for measuring the stretch produced by a stretching machine comprises two hydraulic elements A, B, each consisting of a cylinder provided with a fluid port and a first rod member extending through one end of the cylinder, fluid being displaced from one element A in response to movement of the stretching member 3, and valve means 23 connecting the ports of the hyraulic elements A, B, in a closed hydraulic circuit when a predetermined force is exerted by the stretching member 3 on the workpiece (not shown). In use, a pump (not shown) supplies fluid under pressure into a cylinder 7, thus acting on the piston-rod 6 to pull the gripper head 3 and stretch the workpiece. At the same time a second pump 10 is supplying fluid to ports 17, 18 and 19 of cylinders A, B, excess fluid, being returned to the fluid reservoir 27. As the workpiece stretches, the piston-rod 14 of the cylinder A moves with the head 3, and the rod 15 of the cylinder B is urged hard to the right. When the pressure in cylinder 7 stretching the workpiece reaches a predetermined value, a switch 38 is operated to energize a -solenoid C and move the valve member 23 to the right, thus connecting ports 19, 20 of cylinder B with ports 17, 18 of cylinder A in a closed hydraulic circuit. Piston-rod 15 then commences to move in unison with rod 14 as the dimensions of the cylinders A, B are identical, and an indication of the stretching of the workpiece, beyond its position at the predetermined pressure, is given on a scale 35. A limit switch 36 which may be adjustable, is actuated by the pointer 34 after a certain amount of stretch has been imparted to the workpiece and this energizes a solenoid D to operate a valve 49 and cut-off the supply of pressure fluid to the cylinder 7. As the pressure in the cylinder 7 falls, the switch 38 is again operated, releasing the valve 23 and returning the apparatus to its initial condition. Valve 49 may be manually or automatically released to start a new cycle of stretching. The pistons and rods in cylinders A, B may be replaced by pistons alone, the pointer 34 being held in zero position by a weight instead of by fluid pressure. The pump 10 may be replaced by a fluid reservoir higher than the fluid conduits, a weight being used to return the pointer 34 to the right.

Title: New imidazolines and a process for their manufacture
IPC: A61K31/00
Filed: 1959-05-05
Abstract: The invention comprises pyrazolo-[2 : 3-a]-imidazolidines having the ring skeleton <FORM:0888703/IV (b)/1> or their tautomeric forms which are unsubstituted in all positions or substituted in the 2, 5- and/or 6-position by lower alkyl radicals and in addition to or instead of substitution in the 2, 5- and/or 6-position may be substituted in the 3-position by a halogen atom and which substituted or unsubstituted compounds may be substituted on the secondary nitrogen atom by a lower alkyl phenyl, lower alkyl or lower alkanoyl radical, their therapeutically useful acid addition salts and quaternary ammonium compounds, and the preparation thereof by intramolecularly condensing a 3-aminopyrazole containing in the 2- position a free hydroxyl group attached by way of a saturated carbon chain of 2 carbon atoms, and, if desired, introducing and/or converting substituents and/or, if desired, converting a resulting free base into an acid addition salt or a salt with a free base.  The term "lower" indicates that the group so described contains 1-7 carbon atoms.  Intramolecular condensation is carried out by means of a dehydrating agent such as a strong acid and when the starting materials contain hydrolysable substituents or free carboxyl groups, they may at the same time be hydrolysed and/or decarboxylated.  Ethyl ethoxymethylene-cyanacetate with hydrazine gives 2(b -hydroxymethyl)-3-amino-4-carbethoxy-pyrazole which, on hydrolysis, gives the free acid and the acid on heating gives 2(b -hydroxyethyl) - 3 - aminopyrazole.  Specification 854,632 is referred to.ALSO:Pharmaceutical compositions comprise pyrazolo[2 : 3-a]imidazolidines having the ring skeleton <FORM:0888703/VI/1> or their tautomeric forms which are substituted in all positions or substituted in the 2,5 and/or 6-positions by lower alkyl radicals and in addition to or instead of substitution in the aforesaid positions may be substituted in the 3-position by a halogen atom and which unsubstituted or substituted compounds may be substituted on the secondary nitrogen atom by a lower alkyl phenyl, lower alkyl or lower alkanoyl radical ("lower" indicates groups containing 1-7 carbon atoms) or therapeutically acceptable acid addition salts or quaternary ammonium compounds thereof and a pharmaceutical carrier. The compositions may be in forms suitable for enteral or parenteral administration such as tablets, dragees, solutions, suspensions or emulsions and may contain additional therapeutically valuable substances.  Acid addition salts are formed from inorganic or organic acids.  The preparations exhibit sedative and antipyretic properties and are effective against tumours and vaccinia virus.  Specification 854,632 is referred to.

Title: Transducer means
IPC: G01L1/00
Filed: 1974-04-09
Abstract: 1466461 Flexure transducers SPERRY RAND CORP 9 April 1974 [11 April 1973] 15566/74 Heading G1G [Also in Division 43-5] The flexure transducer as described in Specification No. 1432818 is modified to reduce the tendency of the oscillator circuit utilizing each separate acoustic path to mode-lock with the other, thereby reducing the accuracy of the measurement of the relevant parameter. The invention is embodied in the Fig. 8 arrangement which utilizes pulsed operation, a particular pulse being routed successively along the two paths 10 and 10a on flexure member 11- the time taken for this being measured and the difference between the propagation times along the flexed acoustic paths being taken as the required flexure measurement whereby mode locking is obviated by propagating the measurement signal in one path at a time. Flip-flop 93 alternately actuates switches 91 and 92 when triggered by a pulse output from amplifier 89, and the time the flip-flop is in each state is used in up-down counter 96 to derive the time difference between the propagation time of the pulse along the paths:- (a) switch 91, with switch 92 closed, exciter 15, acoustic path 10, receiver 14, summing circuit 90, amp. 89; (b) switch 92, exciter 15a acoustic path 10a, receiver 14a, summing circuit 90 and amp. 89. Counter 96 counts in opposing directions in response to the polarity output of flip 93 which respectively corresponds to signal paths (a) and (b) whereby other inherent time delays cancel and only the time difference corresponding to the path length difference between the acoustic paths is measured. There is also described, Figs. 5, 6 and 7 (not shown), arrangements wherein the acoustic paths are separately utilized in continuous oscillatory circuits the frequencies of which are chosen to reduce mode locking between the paths.

Title: Improvements in machines for the production of box parts
IPC: B31B50/00
Filed: 1937-06-05
Abstract: 481,008. Making boxes. MULLER, J. C. June 5, 1937, No. 15638. Convention date, July 27, 1936. [Class 18] In a machine for making a box comprising a tray-like member 4, Fig. 6, with a collar 3, a strip for forming the collar is cut from a reel or delivered from a stack 8, Fig. 2, by a pusher 10, over a glueing roller 12, on to a conveyer 15 which carries it in a direction transverse to its previous motion until it is in a position opposite two box-forming devices. A blade 9 ensures that only one strip is delivered at a time. The conveyer is actuated by endless chains passing round sprocket rollers 18 and it is provided with side plates 16 to guide the strips. The leading two strips are drawn by reciprocating grippers, either simultaneously or one after the other, from opposite sides of the conveyer on to pivoted flaps 21, Fig. 3, which are turned immediately to the position shown. A plunger 23 pushes the strip past recessed folding plates 24, which bend it into U -form, and under a further plunger 28 against a support 25 where it is held by fingers which descend into recesses in the plunger 23 before the latter retreats. Pivoted hook-shaped members now swing down to hold the strip while the plunger 28 descends after which the plates 24 move inwards and fold in the arms of the U-shaped strip so that it surrounds the plunger where it is held resiliently by a finger 33 which covers the join in the strip. The finger 33 is pivoted at 34 and is rigidly connected to an arm 35 which is joined by a spring to and can be engaged by an abutment on, an arm 36 loose on the pivot 34. A link 38 connected to arm 36 actuates the finger 33. A cruciform blank having been fed from a roll or pushed by a ram between guides under the plunger 28, the latter, carrying the collar 20, is moved downwards by a link 29, and forces the blank through dies 41 which fold the sides up into contact with the collar, the dies sliding inwards to consolidate the join. During the descent of plunger 28, the finger 33 moves with it until the collar lies between the side flaps of the blank when a screw 48 on a slide connected to the finger abuts against a stop on the machine. The completed box is forced by the plunger on to a table 49 which is also pushed down and, as the plunger is withdrawn, resilient hook-shaped devices hold the box back on the table. A ram 55 subsequently pushes the box on to a conveyer 56.
