Abstract: 1,053,223. Inserting sheet material into envelopes. CAMBRIDGE MACHINE CORPORATION. Aug. 19, 1963 [Aug. 24, 1962], No. 32732/63. Heading B8C. Apparatus for opening and filling envelopes comprises means for carrying each envelope from a magazine to a filling station, fitting it over stationary filling guides where it receives the contents and gripping it when filled to pass it to a delivery station. The latter may include means for folding down and securing closure flaps. The contents may be inserts and a sheet which is folded by the apparatus to enclose them. The apparatus is adjustable for different envelope sizes. Insert feed and sheet feed and folding.-Two insert and one sheet magazines 100, 200 are provided, each having a suction picker operating through the base, Fig. 2, to pull the lowermost article into the bite of feed rollers which urge it between guide plates. The inserts pass from the guide plates on to a conveyer 143 while each sheet is engaged by rollers 301, 302 and fed up a folding guide 303 until it bends into the nip of rollers 302, 305. These feed it folded at about one third of its length to a further guide 306. It then bends between the nip of rollers 305, 308 which fold it about one or more inserts advanced by the conveyer 143 and upper belts 157. The so-formed " package " is moved along fixed guide channels 401 engaging its ends, by rollers, the channels supporting it in readiness for enclosing by the envelope. Envelope feed and filling.-The flap of the lowermost envelope in the magazine 500 is gripped by a suction cup 602, Fig. 3, which rotates to unfold it into the envelope plane. Grippers 714 press the flap on an arcuate member 715, the grippers and member rotating with a shaft 611 and being moved relative to each other by cam-operated gear connections 711. The envelope is pulled from the magazine and supported by a guide 716 is carried to the filling position. Fingers 727 and rollers 717, Fig. 5, cause the envelope to open so as to fit over the channels 401 at which it is released by the grippers. The " package " is pushed into the envelope by a dog 424 on a conveyer 421, Fig. 3, and the filled envelope is removed by a gripper arrangement 803, 813 similar to that 714, 715. It is drawn along a guide 816 and released on to a ramp 850. Oscillating blades 951 normally urge each envelope up the ramp into the path of conveyer dogs 1006, but if a feeler 901 adjacent the filling position detects an envelope leaving the latter which is above or below the normal thickness, it causes locking of the blades beneath the ramp so that the defective envelope falls into a reject bin 851. Closing, sealing and discharge.-Envelopes passing up the ramp are engaged by rollers 1008, 1007, the latter applying solvent or moistening liquid to the flap adhesive. When the flap projects beyond the ramp, a bar 1018 swings down to fold it through about 90 degrees and the envelope passes into the nip of rollers 1025, 1026 to complete the fold. The sealed envelopes are discharged into a bin &c.

Abstract: 1,226,057. Moulding plastics sheets. MITSUBISHI KASEI KOGYO K.K. 15 July, 1969 [17 July, 1968 (3); 7 May, 1969], No. 35477/69. Heading B5A. A flat plate of polymerized plastics material is made by preparing a cell comprising a pair of flat templates 10 separated by a compressible gasket 11, pouring a polymerizable material into the cell, applying pressure perpendicular to the plates to reduce the volume of the cell, compress the gasket and expel air, relieving the pressure and transferring the cell to a polymerization zone where the material is heated and polymerized. The cell is preferably filled by laying one template horizontally with the gasket 10 attached, filling with polymerizable material and applying the upper template with pressure to expel air. Alternatively the gasket may be discontinuous with a gap between its ends and the material may be poured into the inclined cell through this gap. The templates may be formed from ordinary or reinforced glass plate or chromium-plated metal. The gasket must adhere to the template to form an air-tight seal and must be elastic and is preferably rubber or polyvinyl chloride of square or circular cross-section. Polyvinyl tube, either in a continuous loop or with the ends bound together to form a loop is the preferred material. The polymerizable materials are preferably vinyl monomers or mixtures of vinyl monomers, optionally partly polymerized to increase the viscosity, examples being acrylates, methacrylates, aromatic vinyl compounds, acrylonitrile and vinyl acetate and incorporates 0À005-1 wt. per cent of a free radical compound yielding a compound soluble in the vinyl monomer, e.g. organic peroxides and azo-compounds. When the lower template and gasket are laid horizontally for filling, the lower template may be supported on rigid means, e.g. iron, aluminium or rigid plastics or elastic means such as rubber, polyurethane foam or soft plastics, the latter materials being preferred. The supporting means are positioned along the periphery of the template in a region having a width of less than 1/4 of the respective sides of the template.

Abstract: 1,231,902. Automatic voltage control. ITT INDUSTRIES Inc. Feb.19, 1969 [Feb.23,1968] No.8945/69. Heading G3R.  A direct voltage regulator, adapted to form a monolithic integrated semi-conductor component, comprises a reference source including a Zener diode ZD and diode FD, as well as a differential amplifier DV and a power stage LS. The elements ZD, FD which are connected between the respective input terminals A, B, of the amplifier DV and the terminals of the regulated voltage source, have opposite temperature co-efficients so that the source of reference voltage has a small temperature response. The common emitter resistor R3 may be replaced by a transistor having a constant base potential, Fig. 3 (not shown). A variable resistor R1 adjusts the value of the regulated voltage. This resistor may be replaced by a further Zener diode providing additional temperature compensation, Fig. 4 (not shown). In another arrangment, the circuit including the power stage LS is inserted through a series resistor between two input terminals, T4 constituting the common emitter load of the amplifier DV. The differential amplifier is symmetrical and includes collector resistors R5, R6. The power stage comprises transistors T6-T9 controlled from the collector of transistor T1. Resistor R10 and capacitor C form a filter circuit to reduce noise. As a substitute for diodes FD5, FD6, the transistor T2 may be connected to a further pair of transistors to increase the time constant of the filter circuit, Fig. 7 (not shown). In a further embodiment, the power stage comprises a pair of transistors of opposite conductivity types connected to the respective collectors of the differential amplifier which is symmetrically loaded thereby. The two power transistors may be each associated with an emitter follower. The chain of diodes is enlarged to ensure correct operation of the differential amplifier, Fig.8 (not shown).
