Title: Improvements in the preparation of resins from pentaerythrite and maleic anhydride
IPC: C07C51/573
Filed: 1945-08-31
Abstract: Pentaerythritol is purified by crystallization in an oxidising medium, 5 vol. hydrogen peroxide being specified, and maleic anhydride is purified in reducing medium, by crystallization in a solution of sodium bisulphite or by distillation under reduced pressure in a stream of sulphur dioxide.  The products are used in preparing colourless resins by condensation.  In the Specification as open to inspection under Sect. 91 the purification is described as being applicable to polyalcohols and polyacids generally.  This subject-matter does not appear in the Specification as accepted.ALSO:A process for the preparation of colourless and stable resins by the condensation of pentaerythritol with maleic anhydride is characterized in that these bodies are separately purified prior to the condensation, the pentaerythritol by crystallization in an oxidising medium and the maleic anhydride in a reducing medium, these purifications being each completed by a washing operation which eliminates all traces of the reagent utilized in the purification proper.  In an example pentaerythritol is purified by crystallization in 5 vol. hydrogen peroxide, and maleic anhydride purified by distillation under reduced pressure in a stream of sulphur dioxide until on heating the pentaerythritol to fusion, and the maleic anhydride to 150 DEG  C., no yellowing is observed.  After removal of the reagents, condensation at 150 DEG  C. produces a colourless resin.  The maleic anhydride may also be purified by crystallisation for example in sodium bisulphite solution.  The Specification as open to inspection under Sect. 91 comprises a process for the preparation of colourless resins by the condensation of polyalcohols and polyacids in which the polyalcohol is purified prior to condensation. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to apparatus comprising a series of receptacles for use in the pasteurisation or like heat treatment of liquids
IPC: A23L3/16
Filed: 1938-08-03
Abstract: 517,817. Pasteurizing liquids. ALUMINIUM PLANT & VESSEL CO., Ltd., and SELIGMAN, R. Aug. 3, 1938, No. 22928. [Class 49] In apparatus for pasteurizing liquids of the type comprising a series of holding compartments mounted on a rotatable member so that each compartment is brought successively into filling and discharging positions, an electric motor is used to turn the apparatus and to lift and lower a discharge pipe to and from the outlet of the compartment in position for discharge. A holder 2 with compartments 3 is mounted by means of a shaft 10 on a pedestal 1 which encloses the operating mechanism. As shown in Fig. 1 a discharge pipe 20 is in position to open a valve 6 at the base of one compartment 3 and allow the milk therein to flow away through the pipe 20 and a receiver 30. The flow may be controlled by a float 32 which supports a sleeve 31 surrounding the pipe. When the holding period for a compartment is completed a time switch is closed to start an electric motor 18, which turns a shaft 16 and a plate 15 attached to the shaft. A cam on this plate moves a lever which lowers the spindle 22 from which the discharge pipe 20 is supported. The plate carries a pin 14 which in moving can engage with radial slots in a Geneva wheel 12 keyed to the shaft 10. The holder is thus rotated to bring another compartment into ,discharge position and the pipe 20 is then raised again by the lever to allow the milk to flow from this second compartment. A mercury or other switch is arranged to open the motor circuit when the pipe has been raised. The lower end of the spindle 22 may move in a cylinder 40 as a pump plunger to supply oil to operating parts. The holder may be turned manually when desired by means of a shaft 36 journalled in the wall of the pedestal and bevel gearing 35. Specification 394,034 is referred to.

Patent GB-1092841-A (GB)
Title: Pulse generating circuit
IPC: H03K3/43
Filed: 1965-05-31
Abstract: 1,092,841. Pulse circuits. BURROUGHS CORPORATION. May 31, 1965 [Sept. 8,1964] No. 23084/65. Heading H3P. [Also in Division G4]. A circuit for generating a predetermined number of pulses comprises a pulse generator 18 the output of which is arranged to step a counting device (such as a magnetron beamswitching tube 16) arranged to inhibit operation of the pulse generator after the predetermined number of pulses have been generated. As described, the beam of the magnetron beamswitching tube 16 is initially extinguished and the multivibrator 18 inoperative. When a negative-going pulse is applied to one of the spade electrode terminals 38, the electron beam is formed about the group of electrodes associated with that terminal. This raises the cathode potential of tube 16, initiating operation of the multivibrator 18, outputs from which are fed to the target electrodes 20 and, via differentiating capacitors 108, to switching electrodes 28, so as to step the beam towards the right hand (reset) target 9. On arrival at the reset target 9, the next pulse from multivibrator 18, after differentiating at 56 and 60, extinguishes the beam by raising the potential of the reset target. The resulting drop in cathode voltage then inhibits operation of multivibrator 18 and prevents generation of further pulses. The number of pulses generated is thus the complement of the number of the terminal 38 to which the input pulse was applied. The number of pulses in each train is registered by an electromagnetic counter 100.

Abstract: 901,133. Cartons; packaging. IGNELL, R. L. July 1, 1960 [July 4, 1959], No. 23159/60. Classes 18 and 94(1).  A carton comprises hinged panels A, B, C, D, E, F, and corner pieces G connected therebetween and hinged to the panels E, F, at least three of the panels C, D, E, F being scored or creased along a line substantially midway between, and parallel to, the adjacent edges of the panels A, B to allow the carton to be folded flat in a plane parallel to the panels A, B. The inside face of the blank shown in Fig. 1, may be coated with an impervious, heat sealable material or the blank may consist of a laminate of paper and synthetic plastic. To form the collapsed carton of Fig. 2 the blank is folded about the line m extending longitudinally of the panel C and seam zones J and j are heat sealed or glued together to form fin-like flaps which are turned over to lie against the collapsed carton. Each collapsed carton is fed from a supply 5 to a pocket 6 of an intermittently rotating turn table 7 by suction nozzles 9, 10. It passes through a tapering channel 8 which applies forces P, Fig. 3, to the panels C, D so that the carton opens to form a cuboid. Alternatively, outwardly directed forces may be applied to the panels A, B. During this operation the portions G fold about the lines d to form projecting ears. A plate 13 transfers the carton to a pocket 12 of a filling head 11 rotated at constant speed. Sealing flaps 19, 20, the former having shoulders 22, 23, swing into a horizontal position and heat seal three of the ears along a narrow zone extending thereacross and parallel to score lines l<SP>1</SP>, t<SP>1</SP>. A pressing arm 24 opens the rhombic opening of the unsealed ear and a filling tube 25 enters. After filling a flap 21 heat seals this ear. The sealed package is deflected from the head 11 by plates 26, 27 as the flaps 19, 20, 21 return to their vertical position. The package passes on to a conveyer 28 and plates 28, 29, 30, 31 fold the ears there-against after they have been supplied with adhesive through nozzles 33, 34. One ear may be left projecting to form a handle and may be provided with a line of weakness to facilitate opening the carton. To empty the carton one ear portion is cut in a line behind the sealing zone to form a spout. In a modification, Fig. 6, the blank is folded to U-shape and the top panels F1, F2 closed after filling.
