Title: Machine having a guard for protecting the operator
IPC: B27G19/02
Filed: 1976-01-20
Abstract: 1499692 Sawing M/C guard PEDRAZZOLI SpA 20 Jan 1976 [7 Jan 1975] 02166/76 Heading B5L [Also in Division F2] A cutting or cropping circular saw 6, which is carried by a machine head 4 pivotably movable, for cutting a workpiece 3, about a pivot 5 of a ring 1 adjustably turnable on a machine bed 1a, for varying the angle of cut, is surrounded by an articulated guard casing formed of two guard covers 10, 16 which telescope together in a circular manner during the cutting operation to substantially enclose the saw 6 at all stages of the cutting operation to provide maximum safety for the machine operation. The first guard cover 10 is turnably supported by a sleeve 11 journalled on the M/C head 4 and is connected via a pin 14 to one end 18 of a connecting rod 17 the other end 19 of which is hinged to a pin 20 carried by an arm 21 on the ring 1, the second guard cover 16 being fast on the connecting rod 17. In the initial machine loading position of Fig. 1 the articulated guards 10, 16 cover all but a small portion of the saw 6, a small opening being arranged in the underpart of the articulated guard, clear of the operator, for release of swarf chips and cooling fluid, the latter of which is supplied via a cock 24 on the cover 10. As the saw 6 is pivotally lowered to cut the workpiece 3 clamped in a vice 2, the connecting rod turns and relatively retracts the guards 10, 16 to allow the cutting operation to be completed whilst maintaining maximum security i.e. coverage of the saw 6. For servicing the M/C, the pin 20 may be removed whereby the guards 10, 16 can be readily displaced (Fig. 4) for easy replacement of the saw 6. The connecting rod 17 may be replaced by one or more ropes, chains, springs and/or gravitational effect or by a combination of these things or by a rack and pinion or a pneumatic or hydraulic piston/cylinder unit, all not shown.

Title: Improvements in or relating to apparatus for feeding mass-produced articles to a wrapping machine
IPC: B65B35/26
Filed: 1956-01-23
Abstract: 795,705. Feeding articles to wrapping machines. HANSELLA-WERKE A. HENKEL AKT.-GES. Jan. 23, 1956 [Jan. 22, 1955], No. 2178/56. Class 94(1). [Also in Group XXX] A device for feeding toffees &c. to a wrapping machine comprises separate carrier segments 9-15 adapted to receive groups of articles previously assembled and convey them to means for feeding them to the machine (not shown), the segments being arranged to move continuously except for a dwell period when the groups are received. Articles 2 are supplied by a conveyer belt 1 to a rotating wheel 3, into pockets 5 of which the articles are impelled by a brush 4. Each radial row of articles falls from the pockets through apertures (not shown) in a fixed plate 6 forming the pocket base, into pockets 7 in a segment held stationary beneath. The segments 9-15 are slidable on a track 8 and are for most of their travel driven continuously by gears 18 meshing with teeth on their inner periphery. At positions adjacent the article receiving position, however, their movement is controlled by Geneva mechanism comprising arms 19, 20 with rollers 21, 22, which engage radial grooves 23 and arcuate faces 26 on the underside of the segments. Two segments 9, 10 are thus engaged by the rollers 21, 22, in the position shown, one, 9, already filled being advanced to be picked up by the gears 18, and the other, 10, for movement to and holding in the filling position. The articles are fed from the segments to the machine by a vertically reciprocating plunger 17, Fig. 2 (not shown) which also moves in the direction of rotation of the gear operated segments as it travels upwardly. The path followed by the segments may be of any arcuate form, and other means such as chain conveyers may be used to fill the pockets 7.

Title: Improvements in connection with electrical static transformers and analogous apparatus
IPC: H01F27/30
Filed: 1923-01-24
Abstract: 209,607. Tasker, E. E. Jan. 24, 1923. Transformers.-In transformers and analogous apparatus in which means are provided for taking up shrinkage in the coils, the rods c, which follow up shrinkage in the coils under the pressure of springs, are prevented from return movement by devices which bear against or engage their sides. In one form, Fig. 2, a pair of cams or eccentrics f bear on opposite sides of each rod c., the bearing surfaces of the rods or cams being milled or roughened. These cams permit the rode to move in the direction to maintain pressure on the coils, but grip the rods and prevent return movement under the stresses caused by short-circuits or other abnormal fluctuations of current. In a modification, a cam or eccentric is provided on one side only of each rod, the other side engaging a fixed or movable abutment. In another form, Fig. 5, ratchet-toothed plates h on one or more sides of the rod engage ratchet teeth on the rod under the action of springs i.

Title: Process for the manufacture of alkylene substituted phenols
IPC: C07C37/52
Filed: 1929-01-22
Abstract: 304,727. Schering-Kahlbaum Akt.- Ges. Jan. 25, 1928, [Convention date]. Samples furnished. Alkylenephenols are obtained by heating a melt of a dioxydiphenylmethane derivative in the presence of a catalyst comprising a material of porous structure, such as fuller's earth, diatomite, tonsil and the substance known under the Registered Trade Mark of " Frankonite." The dioxydiphenylmethane derivatives contain the two /R2 groups R, and-CH (R1, R2 and R3 repre- \R3 senting hydrogen, alkyl or aryl) directly linked to the methane carbon atom forming the bridge between the two phenolic residues; in addition, the said carbon atom mav itself be a member of a ring system. The starting material may be melted with the catalyst and the temperature maintained below the boiling point of the decomposition products which are then fractionated when the reaction is completed, or the decomposition products are distilled out of the melt under atmospheric or reduced pressure. According to the examples (1) 3-methyl-6-isopropenylphenol and m-cresol are obtained from di-(2-oxy-4- methylphenyl)-dimethylmethane (see Specification 308,741) using tonsil and-" frankonite," (2) p-isopropenylphenol and phenol result when di- (4-oxyphenyl)-dimethylmethane is heated with tonsil, (3) p-isobutenylphenol and phenol are formed by the thermal decomposition of di-(4- oxyphenyl)-methylethylmethane in the presence of " frankonite," Specification 293,863 also is referred to.

Patent GB-371059-A (GB)
Title: Process for the manufacture of dichromates
IPC: C01G37/14
Filed: 1931-01-23
Abstract: Alkali dichromates are obtained by treating alkali chromates in the aqueous phase and in the presence of the requisite quantity of chromium oxide or hydroxide or of metallic chromium or its alloys with oxygen or gases containing it under pressure at temperatures above 100 DEG  C., say at 250-300 DEG  C.  In one example a chromium ore is treated with fused caustic soda in the presence of iron oxide or roost residue at 450-500 DEG  C. to obtain chromate.  A part of the product is reduced by hydrogen under pressure in the presence of water at 300 DEG  C. and the chromium hydroxide recovered mixed with further chromate and treated in the presence of water at 280-300 DEG C. with air or oxygen under pressure to obtain a solution of sodium dichromate.  In another example, crude chromate formed by oxidizing roasting at 900-950 DEG  C. of a mixture of chromium ore, sodium carbonate, slaked lime, and iron oxide, is treated with oxygen under pressure at 280-300 DEG  C. after addition of ferrochrome and water. Carbon dioxide obtained from the carbon in the ferrochrome is bound by the lime present; alternatively by using a current of air instead of oxygen the carbon dioxide may be removed in the issuing gases, but in such case the lime present is preferably converted to carbonate after the oxidation is complete in order to decompose any calcium chromate.  In a third example crude chromate containing lime is reduced to chromite at 400-600 DEG  C. by hydrogen with or without carbon dioxide.  After leaching out alkali the residue is added to crude chromate lye and the mixture oxidized to dichromate as before described.  Carbon dioxide is introduced before or after oxidation to convert lime present to carbonate.  Reference has been directed by the Comptroller to Specification 364,361.
