Title: Alarm device for signalling paper feed faults in tape printers
Inventor: GISKES JOHANNES HERMANUS
IPC: H04L13/06
Filed: 1952-11-12
Abstract: 738,505. Printing-telegraph receivers. STAATSBEDRIJF DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. Nov. 12, 1952 [Nov. 24, 1951], No. 28563/52. Class 40 (3). [Also in Group XVI] In a telegraph receiver using a tape for the messages, a device for giving a signal when the tape is subjected to excessive tension or breaks, comprises a guide roller which changes the direction of the tape feed and is mounted on a pivoted lever, a feeler lever, resiliently urged against the tape, and mounted on a second lever connected to the first lever, and signalling means responsive to movement of the second lever from its normal position by abnormal tension of the tape or absence of the tape around the roller. As shown, the tape 10 passes over the idler roller 11 supported in arms 12, 13 pivotally mounted on a shaft 14 and passing through slots 19 in the cover of the casing 15. The feeler lever 20 is adjustably mounted on a lever 25 by a screw 26 passing through an arcuate slot 27 in the wall of the casing. The ends of a spring 30 are attached respectively to a pin 31 on one of the arms 12, 13 and to a pin 32 on a sleeve 33 secured to the lever 25. When the tension of the tape 10 increases, the roller 11 is raised so that by the agency of the spring 30 the lever 25 carrying the feeler 20 is rotated until the screw 26 engages the end of the slot 27. A cam surface 47 on the lever 25 engages a stud 48 on the contact spring 42 to open contacts carried by springs 41, 42 and to close contacts of springs 42, 43 in the circuit of an alarm device which may be audible or visible. If the tape breaks or the supply fails, the end of the feeler lever 20 passes through a circumferential groove 17 formed in the roller 11 so that the lever 25 moves counterclockwise to close contacts on springs 42, 43. To indicate the condition of the supply roll, a lever 53, associated with the roll, operates a slidable plunger 51 engaging a stud 50 on the contact spring 45 to close contacts carried by the springs 44, 45 to operate an alarm device.

Title: Process of coating rotating filtering frames
IPC: B01D37/02
Filed: 1922-10-26
Abstract: 201,822. Vallez, H. A. Oct. 26, 1922. Rotary filters.-In a process for coating rotary filtering-frames with a paper pulp mixture, the washed pulp is mixed with clear filtered or unfiltered liquids and is circulated through the filter under pressure until a coating of the desired thickness is obtained. After use, the coating is removed and returned to the wash tank. The pulp is boiled and soaked in a tank 16, and after draining is mixed with clear liquid in a tank 17. A pump 21 serves to force the mixture through the pipes 19, 20, 22 to a pipe 23, fitted with branches 23<a> which communicate with the filter 1. Tha mixture filters through the rotating frames 5, which comprise spaced screens 7, 8, Fig. 5. Pulp is deposited on the faces of the screens, and the liquid is returned by the hollow shaft 6 and pipe 27 to the tank 17. The pulp in the tank 17 may be mixed with clear water, in which case the water remaining in the frames may be forced out by compressed air before filtration begins. The liquid to be filtered is pumped from the tank 31 through pipes 22, 23, 23<a> into the filter, and the filtered liquid passes off through the pipe 32. To prevent caking of the deposit on the frames, a little pulp is added during the filtering process. When the filter requires cleansing the supply from the tank 31 is cut off, and the liquid in the filter is returned through the pipe 33 to the tank 31. The filter is flushed with water from the pipe 25, and the water issues through the pipe 35. Finally the filter is half filled with water, compressed air and steam are supplied from the valves 14, 15 and a perforated pipe 13, and water and compressed air are supplied from the valves 11, 12 and the spray-pipe 10, whereby the pulp and sediment are disintegrated and held in suspension in the water. The mixture is now forced back to the tank 16 through the pipe 34, to be washed preparatory to further use. A pipe 39 is provided to withdraw water used to wash the filter.

Patent GB-972403-A (GB)
Title: Preparation of unsaturated aliphatic aldehydes
Inventor: EYGEN CYRILLE VAN
IPC: B01J23/888
Filed: 1962-07-30
Abstract: Unsaturated aliphatic aldehydes are produced by contacting at elevated temperature in the vapour phase a gaseous mixture of an olefine and oxygen with a catalyst containing arsenic, tungsten and oxygen.  The catalyst may also contain molybdenum oxide and/or iron oxides and may be deposited on a suitable carrier, in particular silica gel. The catalysts may be used in the form of grains or powders which may be pelletted. The reaction gases may contain a diluent gas, e.g. nitrogen, propane, oxides of carbon or water vapour. The preferred reaction temperatures are in the range 300-700 DEG C. The activity of the catalyst may be maintained by passing a volatile oxygenated compound of arsenic, for example arsenic trioxide, into the reactor with the reactants. Alternatively, the volatile arsenic compound may be introduced as a solution, for example, in water or hydrochloric acid.  Examples are given of the oxidation of propylene and isobutylene to acrolein and methacrolein respectively.ALSO:A catalyst for use in the oxidation of olefines to unsaturated aldehydes comprises arsenic, tungsten and oxygen with optionally molybdenum and/or iron.  The catalyst may be supported on conventional supports, e.g. silica gel, Al2O3, BPO4, TiO2, BeO, pumice, SiC and AlPO4. Preferably the arsenic, tungsten and oxygen are used in the form of arseno-tungsten acids.  Before use the catalyst may be activated by treatment at 100-500  DEG C. with air, water vapour or inert gases.  Preferably the catalyst has a surface area of less than 200 sq.m./gm. and it may be used in a fixed bed, a fluidized bed or a moving bed.  The activity of the catalyst may be maintained by passing a volatile oxygenated compound of arsenic, e.g. arsenic trioxide, in the form of a vapour or as a solution in water or aqueous hydrochloric acid, into the reactor along with the reactants.
