Title: Improvements in or relating to the cross-linking of olefin homopolymers and copolymers
IPC: C08L23/00
Filed: 1970-10-05
Abstract: 1294154 Crosslinking olefin polymers SIEMENS AG 5 Oct 1970 [16 Oct 1969] 47285/70 Heading C3P  Olefin polymers are crosslinked by heating in the presence of at least one tertiary peroxide and 0À1 to 20 weight per cent, based on the polymer, of at least one radical transfer agent selected from acridine and acenaphthylene and halogen and aryl derivatives thereof. The radical transfer agent reacts with alkyl radicals formed during the crosslinking to form a resonance stabilized radical intermediate which is then saturated by hydrogen split off from the polymer. Specified peroxides are dicumyl peroxide, di - t - butyl peroxide, 2,5 - bis - t - butylperoxy - 2,5 - dimethylhexane, 1,3 - bis - (tbutylperoxy) isopropyl benzene, n-butyl-4,4- bis-(t-butylperoxy) valerate and 2,2-bis-(t-butylperoxy) butane. The transfer agents may be blended directly with a polymer melt, or added as a solution or dispersion in a liquid medium, e.g. chlorinated diphenyl, which enhances the effect of the agent. Examples describe the crosslinking of (1) polyethylene with dicumyl peroxide or 1,3-bis-(t-butylperoxy) isopropylbenzene in the presence of acenaphthylene, with and without chlorinated diphenyl; (2) polyethylene with dicumyl peroxide in the presence of acenaphthylene; and (3) ethylene/propylene rubber with 1,3-bis-(t-butyl peroxy isopropyl benzene in the presence of acenaphthylene, with and without chlorinated diphenyl. The acenaphthylenes are said to function additionally as antioxidants.

Title: Improvements in rotary printing presses
IPC: B41F21/10
Filed: 1968-10-08
Abstract: 1,237,724. Printing apparatus. SOC. NEBIOLO S.p.A. 8 Oct., 1968 [14 Oct., 1967], No. 47550/68. Heading B6C. [Also in Division F2]  To prevent loss of printing register due to torsional twisting of co-operating sheet-carrying members in a printing press, engaging impression cylinders and/or transfer cylinders are provided with auxiliary synchronizing means which correct deviations from the nominal register imposed by the drive to the cylinders. Gripper-bearing cylinders 3, 8 each carry a length of toothed gearing, that on cylinder 3 following an arc of a circle concentric with the cylinder axis C1. The length of gearing on cylinder 8 also follows an arc of a circule, smaller in diameter than that of the length on cylinder 3 and mounted eccentrically with respect to the axis of cylinder 8. As the cylinders 3 and 8 rotate the toothed arcs mounted on them come into contact. Initially the teeth at the ends of the arcs engage, and due to the different diameters of the arcs considerable play exists and relative distortions due to torsion are accommodated. When the central parts of the arcs engage however, no play is possible, and the cylinders are forcibly brought into synchronism during transfer of sheets between grippers 24 and 23. Transfer cylinders linking two rotary offset printing units may be synchronized by pairs in this way, so that a sheet may receive two impressions in register.

Abstract: 1531765 Selective printing ADDRESSOGRAPH MULTIGRAPH CORP 20 Nov 1975 [10 March 1975] 47845/75 Heading B6F [Also in Division G4] A data recorder -for commercial transactions has ten sliding manual keys, viz. two sets of four amount keys and two code keys, which position (via racks and pinions) ten type wheels in a main printer which also has four type wheels (settable with a stylus) for the date. One of the two sets of-amount keys and one of the code keys also position five type wheels in an auxiliary printer which also has four date type wheels. One of three push-buttons is pressed to select the type of transaction (cash, credit or subaccount). The key settings are also sensed by rotary switches. A diode matrix responds to the setting of:one of the code keys and the pushbutton selection to check the validity of the transaction. If invalid, following logic lights an appropriate error .lamp, but if valid, the logic releases a platen in the main printer for imanual movement across the print bed to print from the type wheels and from embossed cards positioned in the bed. The logic is responsive to platen limit switches, a "card present in the bed" switch and a mains failure switch. When the platen has been manually returned after printing, the logic enables entry of key settings and operation signals into two calculators, and actuates the auxiliary printer after selecting its ribbon colour. Two push-buttons permit the result in either calculator to be displayed on a common display.

Title: Improvements in or relating to the manufacture of tubular sleeves by extrusion in sheet and plate metal products
IPC: B21D22/04
Filed: 1965-11-17
Abstract: 1,129,701. Making mounting pads; pressing; swaging taps, drills; presses. MONARCH RUBBER CO. 17 Nov., 1965 [17 Nov., 1964], No. 48760/65. Headings B3A, B3C, B3H, B3N and B3Q. A tubular sleeve is formed from a sheet metal blank by forming a cylindrical hole in the blank and pressing the blank, in the region of the circumference of the hole, into the shape of a sleeve, the inner and outer walls of the sleeve being defined by inner and outer dies. The sleeve can then be bonded to a rubber block, reamed, and internally threaded to produce a composite article 2, Fig. 22. The blank 1b, Fig. 4, is positioned between a spring loaded ejector plate 49 and composite die 24, 25, the nose 50 of a punch 48 being located in a pierced and then sheared hole 22 of the blank. The tubular portion 34 of a piston 33 underlies the blank, the piston being hydraulically connected with a further piston 43. As a ram 46 is lowered, the rod 44 of a piston 43 is first contacted, resulting in a pressure being exerted hydraulically on the piston 34, the pressure progressively increasing on the die 48 forms a tubular part 57 (Fig. 7) on the blank. The die finally forms a chamfer 59 on the blank by means of a shoulder 54. The initial pressure of the fluid 38 can be adjusted by means of a supply unit connected to inlet 40, a bleed or pressure relief valve 68 also being provided. If the sleeve 57 requires to be accurately sized for length, the blank is pressed between further dies (Fig. 8, not shown), or the piston 33, incorporated in the existing press, is urged upwardly against the base of sleeve while the blank is held in position, the previously formed chamfer in each case being removed by the resulting metal flow. The formed blank, after bonding to a rubber block, Fig. 10, is reamed by a tool 84 to remove any rubber waste and also a thin work hardened skin of the sleeve. A thread is then swaged in the sleeve by a tool 85 without the removal of metal. More than one sleeve may be formed, if desired, in the metal blank, and the exterior of each sleeve may be threaded rather than the interior. When a bolt is engaged with an internal thread on the sleeve with a given torque loading a self locking action is obtained due to distortion of the sleeve.

Abstract: 1344798 Reciprocating pumps DEERE & CO 24 Oct 1972 [11 Nov 1971] 49027/72 Heading F1A A hydraulic control system for a variable displacement pump, 10, Fig.1, in which a piston 12 is reciprocated by an eccentric 18 in a drive chamber 16 and is returned by the pressure in an inlet line 22, the return stroke is limited to an extent determined by the pressure in the drive chamber which is controlled by a valve 46. In operation, when the valve 46 is as shown, pressure from a charge pump 32 is connected to the drive chamber 16 and also to the underside of piston 14 thereby preventing the pressure in line 22 from returning the piston, i.e. the pump goes out of stroke. When a hydraulic device 30 is put into operation there is a pressure drop in a supply line 24 and a pilot line 50 so that a spring 48 moves the valve 46 to the left to connect a line 20 to the reservoir. This reduces the pressure in the drive chamber 16 and on the underside of piston 14 so that pressure in the line 22 returns the piston and the pump feeds fluid to line 24 for as long as pressure in that line and the pilot line 50 is insufficient to overcome the force of the spring 48. In a second embodiment, Fig.2. (not shown), the control valve 46 is made responsive to load pressure in addition to the pressure in the line 24 by connecting pilot lines 70, 74 to a pilot line 68 which acts in opposition to the pilot line 50. A 3-way valve 66 has a central "off" position and two other positions in which fluid is fed and exhausted to operate a double-acting ram 52.
