Abstract: 639,975. Ice cream dispensers. BERRY, T. and BERRY, S. June 14,1948, No. 16013. [Class 87 (ii)] The number of portions of ice cream dispensed is counted by a counter 4 contained in the hollow handle 3, the counter being operated by the rotary movement of the ejector shaft 5 through a spring 11 which transmits torque in one direction only. One end of the spring is secured to the ejector shaft 5 and the other end fits over the counter driving spindle 10. When the shaft 5 is turned to operate ejector 14 (by means of thumb piece 9, sector 7 and pinion 6) the spring tightens on spindle 10 and turns it. When the thumb piece is released a spring (not shown) returns the parts to their normal position and the spring 11 unwinds and slips around spindle 10 without rotating it. In modifications :-(1) The spindle may be turned only when the thumb piece is released i.e. on the return movement of the ejector. (2) The counter may be disposed outside the handle and may be driven by the end of the shaft 5 either directly or through gearing. (3) The counter may be connected to the rack or to the rack pivot pin. In these modifications the means for transmitting the torque in one direction only may be incorporated in the counter.

Patent GB-492073-A (GB)
Title: A process for the preparation of catalysts for the synthesis of methanol
IPC: B01J23/06
Filed: 1937-06-10
Abstract: A zinc oxide catalyst for methanol synthesis is obtained by the thermal decomposition of an organic zinc salt whose melting point is lower than its decomposition point, e.g. zinc acetate.  Other oxides which are not reduced in the conditions of use may be incorporated in the zinc oxide, preferably by addition of organic salts of the kind referred to.  The decomposition may be effected under pressure and at the lowest possible temperature, and the product may be ground to a porous granular structure.  Since the catalyst also favours the conversion of water gas, the synthesis gas may have an abnormally low hydrogen content, the deficiency being supplied by an addition of steam according to the equation 3CO + 3H2 + H2O = CO2 + 2CH3OH.ALSO:A zinc oxide catalyst for methanol synthesis is obtained by the thermal decomposition of an organic zinc salt whose melting point is lower than its decomposition point, e.g. zinc acetate.  Other irreducible oxides preferably prepared by similar means may also be present.  The catalyst also favours the water-gas reaction and thus permits the use of a synthesis gas of abnormally low hydrogen content with an addition of steam, according to the equation 3CO + 3H2 + H2O = CO2 + 2CH3OH.

Filed: 1954-06-02
Abstract: 773,077. Electric digital-data-storage apparatus. TELEFONAKTIEBOLAGET L. M. ERICSSON. June 2, 1954 [June 2, 1953], No. 16367/54. Class 106 (1). In the arrangement described in Specification 773,075 wherein data stored in a secondary emission multi-anode thermionic tube is continually being read and maintained by applying a train of positive pulses to the control grid of the tube, the data is introduced into the tube by a pulse generator G, Fig. 6, which produces triangular shaped positive pulses so timed that their vertex occurs just as the leading edge of a positive pulse reaches the control grid. In order to cause an anode to assume its " high " condition a triangular pulse with a very steep leading edge and a relatively slow decay is used. Such a pulse if of the appropriate magnitude will bring the potential of an anode previously in the " low " condition to a point D, Fig. 5b, from where it will pass, as the primary electron flow commences first to point E and then to point C, during the period from points E to C, the triangular pulse will decay to zero but its effect will be of no consequence. To change an anode from its "high " to its low condition, a pulso with a slow rise and a rapid decay is used. The potential of the anode is then taken from point A, Fig. 5a, where it will be just before the primary electron flow begins, to a point D, from where it passes via point E to point O. The effect of the triangular pulses on other tubes when several tubes are arranged in parallel, as in Specification 773,075 is of no consequence, and thus data can be entered selectively into any one tube by arranging forthe vertex of the traingular pulse to occur at the appropriate time.

Title: Multi-roll calender for rubber or synthetic plastics material
IPC: B29C43/58
Filed: 1976-04-22
Abstract: 1492251 Calenders HERMANN BERSTORFF MASCHINENBAU GmbH 22 April 1976 [24 May 1975] 16369/76 Heading B5A In a multi-roll calender there is provision to move a pair of rolls either in unison, perhaps with reference to a further roll, or to move one roll relative to the other to alter the gap between them. In the described embodiment, a pair of rolls are carried by journals 511 and 512. One journal 512 is carried by a bearing block 16 slidable along guide grooves 545 of the calender stand 514 and the other journal 511 is carried by a mounting member 544 slidable along guide grooves 543 of the bearing block. Projecting upwardly from the mounting member is a screw threaded spindle 23 which passes through an internally threaded sleeve 516 rotatably mounted in a cross-member 13 of the calender stand. The upper end of the sleeve is fixed to a worm gear 529 driven by a worm 534 and engageable via an electromagnetic coupling 527 with a spur gear 528 rotatably mounted around the sleeve. The spur gear co-operates with two further spur gears 525, 526 each of which is carried by a further internally threaded sleeve 515 or 517 also mounted in the cross member 513. Each sleeve contains a screw threaded spindle 22 connected to the upper surface of the bearing block 16. In operation, to move the rolls in unison, the coupling is energized to connect the spur gear 528 to the worm gear so that rotation of the worm gear by the worm 534 causes rotation of the spindle 23 directly and rotation of spindles 22 indirectly through spur gears 528, 525 and 526. Thus the bearing block and mounting member are moved together. To alter the gap between the rolls the coupling is de-energized to disconnect the spur gear 528 from the other spur gears, this causing only the spindle 23 to be rotated by the worm gear, and thus only the roll carried by journal 511 to move. The invention finds use in the calendering of plastics or rubber by a five-roll L-calender (see Fig. 1, not shown), a six-roll L-calender (see Fig. 2, not shown) a four-roll Z-calender (see Fig. 3 not shown) or a seven-roll L-calender (see Fig. 4, not shown).
