Title: Improvements in expanded rubber
Filed: 1938-04-20
Abstract: 514,944. Gas-expanded rubber. EXPANDED RUBBER CO., Ltd. (Rubatex Products, Inc.). April 20, 1938, No..11895. [Class 70] A condensed gas, such as solid or liquid carbon dioxide, is heated and vaporised within a sealed chamber containing rubber dough, consisting of natural or synthetic rubber, fillers and sulphur, or in a chamber communicating with a closed chamber containing the dough. When the rubber has been partially vulcanized, the excess gas pressure is released. The temperature is then raised to vulcanization temperature and maintained thereat until vulcanization is complete, or the rubber may'be cooled, removed from the gassing chamber and the expansion and vulcanization completed. An inert gas, such as nitrogen, may be introduced in addition to the carbon dioxide in order to prevent the collapse of the rubber due to diffusion on releasing the pressure. Oxygen is removed from the chamber before introducing the rubber dough, either by evacuation or by replacement by an inert gas.

Title: Improvements in Tabulating Machines.
Inventor: HOLLERITH HERMAN
Filed: 1917-08-29
Abstract: 117,985. Hollerith, H. Aug. 29, 1917. Statistical machines.-In electrically-operated tabulating-machines of the Holleritti type employing perforated record-cards, means are provided whereby the previously sorted cards of different series are fed continuously, the machine being stopped when the end of a series is reached without the use of stop cards inserted between the different series. In the form shown in Figs. 1 and 3, the invention is applied to cards having two sets of perforations only, one set representing the series and the other the matter to be registered on the totalizer. Two sets of vertically-disposed brushes 24, 22 are employed for engagement with the series perforations and a single set, (not shown), situated on a level with the brushes 22 for the operation of the totalizer. The brushes 24 are wider than the brushes 22 and serve to detect a change of identity in the series being fed. The cards are fed from a platform 7 by a crosshead 16, reciprocated in synchronism with feed rolls 9, 13, 14, to a receptacle 15. While cards of the same series are passing and the brushes 24, 22 are in engagement with their contacts 25, 23, control magnets 30 remain energized and the machine continues to operate, contacts 32, normally closed by armatures 31 of the magnets 30, remain. ing open. Should a card of a different series prevent the engagement of the brushes 24 with their contacts, the magnets 30 are de-energized and control magnets 35 and relay magnets 36 are energized, thus breaking the main circuit at contacts 38. The main circuit however remains closed until contacts 39, 43 are broken simultaneously or successively by cams 40, 45 which operate in synchronism with the feed rollers and open the circuit at a period between the passage of two cards, the machine then being stopped. When the last card of a number being dealt with is passing, the main circuit remains closed until broken by card-operated contacts as described in Specification 27067/07. In a modification where the controlling means is situated in the main circuit, a register may be operated showing the particular series operated upon. Specifications 10502/01 and 27072/04 also are referred to.
