Title: Improvements in or relating to counting mechanisms
IPC: G06M1/34
Filed: 1957-11-08
Abstract: 847,962. Counting-apparatus. PANDOZY & FIGLI S.r.I., G. Nov. 8, 1957 (Nov. 14, 1956], No. 34925/57. Class 106 (1). In a numeral wheel counter, zeroizing is effected without disengagement of the transfer pinions, by means of pawls pivotally carried by the wheels and adapted to engage with longitudinal grooves in the numeral wheel shaft. As shown, the numeral wheels 4 of a counter adapted for printing are mounted on a shaft 3 carried by the casing 2 and separated by spacers 14 supported on a shaft 15 carried by the casing. The numeral wheels each bear two series of numerals 0-9. The lowest order numeral wheel 4<SP>1</SP> is driven by a rotary gear 8<SP>1</SP> meshing with gearing 5<SP>1</SP> on the wheel. The higher order wheels are driven through transfer mechanism comprising two diametrically opposed transfer teeth 6 on the lower order numeral wheels, corresponding to the two series of numerals, which teeth are adapted to co-operate with transfer pinions 9 mounted on a shaft 7 and separated by spacers 13, the transfer pinions being in mesh with gearing 5 on the higher order numeral wheels. Alignment of an indicated number is effected by the pressure of balls 12 between the two adjacent teeth of the transfer pinions and in the case of the lowest order wheel by a pinion 8 coaxial with the transfer pinions, the pressure being maintained by the action of the springs 11. The pinion 8 also serves to prevent over-running when a counting operation ceases. Zeroizing.-The numeral wheel shaft 3 is rotated through one revolution by the knob 19 whereby longitudinal grooves 16 co-operate with pawls attached to the wheels to return them to zero. The pressure of the balls 12 on the transfer pinions 9 and the pinion 8 acts frictionally to prevent premature rotation of the numeral wheels. The zero position of the shaft 3 is determined by the co-operation of a projection on a spring-biased lever 23 with a notch in a circular cam disc 20 fixed to that shaft 3.

Title: Improvements relating to apparatus for feeding molten glass
IPC: C03B7/06
Filed: 1921-12-29
Abstract: 195,448. Pitt, H. H. Dec. 29, 1921. Delivering molten metal.-A feeder for delivering gathers of molten glass to a forming-machine comprises a damper for controlling the flow of hot gases from the furnace, a gate or valve for regulating the flow of metal along a forehearth or spout, and a reciprocating plunger which is cooled internally and is fitted with a suction device for intermittently retarding the flow of metal through an orifice in the forehearth. The metal passes from the furnace 21, Fig. 1, through a channel 20 to the plunger 23, the flow of metal being regulated by a gate 22 and its temperature being controlled by a damper 24. This damper consists of an iron or steel box through which water is circulated to enable its temperature to be controlled. The adjustable gate 22, Figs. 1 and 8, is formed at its lower end with a central depending tongue 28. Thus when the gate is raised to the position shown in Fig. 1, the metal flows around the tongue and along the side portions of the spout. It is stated that this retardation of the central and hotter portion of the stream of metal maintains a more uniform temperature throughout the metal. The reciprocating plunder 23, shown in section in Fig. 6, consists of an outer cylinder of refractory material provided with a non-conducting lining 33 within which are three concentric steel tubes 34, 35, 36. The inner tube 36 forms a chamber for the circulation of cooling water, and also co-operates with the tube 35 to form a very narrow annular chamber which is connected with a vacuum pump. Suction is applied at the commencement of the upstroke of the plunger and its effect is to retain and lift the metal out of the feed aperture 31, Fig. 1, so that fresh, hotter metal flows beneath it. The narrowness of the annular chamber prevents the entry of metal, and the cooling of the plunger prevents the metal from sticking to the bottom. The suction is released near the top of the upstroke so ,as to free the chilled metal. The movements of the shears 48 and of the plunger. and also the application of the suction, are all controlled by valves which are actuated by cams on a common shaft. Means are provided, in connection with the valve operating the shears, for giving an additional impetus to the blades immediately they have cut the glass, whereby they are instantly withdrawn and chilling by the shears is avoided.

Title: Resilient mounting element
IPC: F16F1/38
Filed: 1968-07-22
Abstract: 1,223,469. Injection moulding. SOC. APPLICAZIONI GOMMA ANTIVIBRANTI "SAGA" S.p.A. 22 July, 1968 [29 Sept., 1967], No. 34962/68. Heading B5A. [Also in Division F2] In a rubber-bush mounting element of the kind in which a rubber tube is secured between inner and outer more rigid tubes, the rubber is vulcanized and at least one of the "rigid" tubes (i.e. either the inner or the outer or both) is of a resilient plastics material such as nylon. The invention provides a method of making such an element whereby it is ensured that shrinkage strains set up in the rubber when it is vulcanised are taken up by resilient deformation of the plastics tube or tubes. In Fig. 1 the inner tube 10 is of metal and the outer tube 12 of plastics and they are shown fitted in a mould chamber 24 whose inner diameter exceeds the outer diameter of the tube 12. When unvulcanized rubber is forced into the mould through inlets 26 the outer tube is deformed. The extent of this deformation, determined by the difference in diameter between chamber 24 and tube 12, is such that it is at least equal to and preferably exceeds the anticipated shrinkage of the rubber upon vulcanization. The rubber is vulcanized in situ and the completed element may be heat treated to shrink the plastics tube 12, after removal from the mould.

Abstract: A process for the production of aromatic carboxylic acids comprises catalytically oxidizing with molecular oxygen at an elevated temperature a substituted aromatic stock in the liquid phase in presence of a C2-8 aliphatic monocarboxylic acid as solvent, collecting a gaseous stream containing solvent vapours from the oxidation zone and condensing a part of them by cooling and returning the condensed part to said zone, recovering the remaining solvent (1) in the gaseous stream by scrubbing with water or aqueous solvent, withdrawing a product-containing liquid effluent from said zone and crystallizing product therefrom in a plurality of series-converted zones by removal of solvent vapours at successively lower temperatures and pressures, recovering an aqueous solvent stream (2) from such vapours, withdrawing a slurry of product crystals in mother liquor from the first crystallizing zone and separating crystals from mother liquor, fractionating the latter to recover aqueous solvent (3), combining the aqueous solvent streams (1), (2) and (3) and fractionating to obtain a dehydrated solvent stream which is used for washing the product crystals and/or charging to the oxidation zone. The process is stated to be particularly suitable for converting mixed xylenes or mixed toluic acids to mixed benzene dicarboxylic acids in such a form that they may be separated into substantially pure phthalic acid (or anhydride), isophthalic acid and terephthalic acid.  The usual catalysts and promoters are mentioned. Specifications 807,091, 835,733, 970,492 and U.S.A.  Specification 2,416,344 are referred to.
