Title: Rocking chair
Inventor: SMART GERALD RUPERT
IPC: A47C3/025
Filed: 1967-10-27

Patent GB-1073795-A (GB)
Title: Methods and apparatus for forming fins on containers made of thermoplastic material
IPC: B29C67/00
Filed: 1963-12-16
Abstract: 1,073,795. Sheet forming. A. H. COLE. Dec. 16, 1963 [Sept. 23, 1963], No. 49606/63. Heading B5A. A ribbed article is pressure formed from flat thermoplastic sheet material using a mould cavity the wall of which includes at least two relatively movable portions which form between them one or more recesses. After initial forming of the article, the portions are moved together so that the material located therebetween is compressed to form the desired rib or ribs. In the example described a continuous sheet of material is indexed between radiant heaters to a forming station at which it is peripherally clamped and plug-assist blow moulded into a female mould. The mould comprises an upper region (34), fixed to a supporting platen, a middle region (36) and a lower region (38). The middle region comprises four sets of relatively movable members 312-322 which define between them recesses b-f, each member being stepped relative to the next and each set of members being carried by a quadrant member 310 biased outwardly by a spring but maintained normally in the inward position by suitable retractable cam means (452, 476). Upper and lower recesses g and a are formed between members 310 and 312, and member 322 and the lower region of the mould respectively. In operation, after the sheet has been formed into the mould the lower region thereof is moved upwardly to compress the material in recess a. This causes member 322 to be raised to compress the material in recess b and this is repeated for each recess, the members 322-312 being sequentially raised until member 312 abuts member 310. After this the cam means is retracted to allow the members 310 and consequently members 312-322 to move outward whilst simultaneously the mould lower region is relowered to allow the members 312-322 to fall back to their starting positions under gravity, the formed article thus being released from the mould ready for ejection on a bottom ejection plunger. Positive means may be used to afford the return of the recess forming members to their starting positions (see Figs. 3 and 4, not shown).

The domed top 3 has a filler hole 33 which receives a flexible tube 35 fitted with a removable cap 43. The rim 21 of the elliptical base 5 is indented 19 and notched 41 and defines with the top 3 a trough 32 which serves to receive water which spills on filling through the hole 33 or through holes in the top 3 made by the stems F2. The trough 32 may also serve as a water supply reservoir in which case an opening is provided in the lower part of the top 3 to permit adsorption by the filler 31.

Abstract: 1415866 Pneumatic activators A DEJOUX J CAMION E CAMPOT J CONNEAU S CONTIVAL J DETTON M GOURNELLE AND A TRAIMOND 6 Nov 1972 [5 Nov 1971] 51085/72 Heading F1D [Also in Division B3] A pneumatically operated ram apparatus comprises a cylinder 1 with a piston 5 which divides the cylinder into first and second chambers 22, 23 which are normally connected to a vacuum and can be selectively connected to atmospheric pressure or compressed gas, e.g. nitrogen, to effect a working and a return stroke. The second chamber 23 is smaller than the first chamber and is connectable to atmospheric pressure or compressed gas pressure by a solenoid valve VAT 2 in a large cross-section inlet passage 27 which allows rapid introduction of air or gas to effect a rapid stroke, the first chamber 22 being maintained in connection with the vacuum. The piston rod 9 of the piston has a striker 16 which is held in its upper position by a rotatable cut-away pin 18. The pin is rotated to release the striker at the same time as the valve VAT 2 is opened. A manometer (M), Fig. 2 (not shown), in the line from the first chamber 22 to the vacuum pump delivers a signal when the desired low pressure is reached to allow initiation of an impact stroke. The ram apparatus is used in conjunction with a punch 42, Fig. 3, and die 32 to cause impact of the punch on material in the die. The ram apparatus is mounted on columns 33 extending from the die 32 and the punch 42 is mounted on a plate 39 slidable on the columns. The material to be worked is held in a crucible 44 which is removed from the die 53 by hydraulic pressure in a chamber 48. The die is mounted on a plate 52 floating on lead or anchored to a large concrete block in a bed of sand. Several piston-cylinder assemblies may be used in series and actuated simultaneously, Fig. 4 (not shown), or alternatively the piston-cylinder assemblies may be parallel and side-by-side, Fig. 6 (not shown). The ram apparatus may act upwards, downwards, or horizontally and may act in opposition to a similar ram apparatus on a floatingly arranged die.

IPC: C01B19/00
Filed: 1965-12-02
Abstract: Crystals of rare earth chalcogenides are prepared by compressing a rare earth chalcogenide powder, placing the resultant body of compressed powder in a crucible, sealing the crucible in a manner such as to exclude gases which react with the body, heating the body within the sealed crucible to a temperature of from 100 DEG  to 300 DEG  C. below the melting point of the powder for a period of from 1 to 4 hours (preferably 2 hours) and allowing the powder to cool for 1 to 4 hours (preferably 2 hours).  Cooling may be prolonged by applying heat to the powder. The sealing of the crucible may be performed whilst the crucible is evacuated or in a chamber containing only gas which is inert with respect to the powder, preferably helium.  The crucible may consist of Ta, W, Ir or Re and the rare earth chalcogenide may have the formula MA or M2A3 where M is La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Sc or Y and A is O, S, Se or Te.  The powder may also consist of a mixture of rare earth chalcogenides. The body may be contained in the lower portion only of the crucible and the inside of the crucible may be pointed, the body of compressed powder having a complementary shape.  A seed crystal may be disposed at the point of the crucible. Heating may be accomplished within a limited heating zone and the crucible and the zone may be progressively moved relative to one another to cause the crucible to leave the heating zone in a direction such that the bottom of the crucible is withdrawn first.  The heating may be effected by electric induction and the heating zone may remain stationary while the crucible is moved by means of a rack and pinion.
