Title: Improvements in and relating to roller shutters
IPC: A62C2/16
Filed: 1932-11-08
Abstract: 408,044. Preventing fires. BOOTH, J., BOOTH, T., and BOOTH, C. H., Hulton Steelworks, Bolton. Nov. 8, 1932, No. 31555. [Class 47 (ii).] A roller shutter of the kind associated with I a heat-sensitive device which is arranged to allow the shutter to descend in case of fire, is associated with mechanism which comes into operation automatically to facilitate the raising of the shutter and its retention in a raised position, after an emergency closure has occurred. As shown, a cable 1 embodying a fusible link, failure of which releases the tension of the counterbalancing springs of the shutter, is connected at its free end to a lever 5 one arm 7 of which holds a rod 8 in raised position. The lower end of the rod 8 is connected to a cam 13 keyed to a shaft 14 on which a pawl 20 is secured. The latter is adapted to co-operate with a ratchet 21 on a shaft 22 which carries a handle 26 and a bevel gear 28 adapted to drive a re-winding shaft 30 which, at its upper end, is operatively connected to the barrel of the shutter. A sleeve 34 threaded on the shaft 30 carries a striker 35. When the fusible link fails in case of fire, the shutter falls and the lever 5 is released. The consequent release of the rod 8 leaves the cam 13 free to turn. Descent of the shutter rotates the shaft 30, causing the striker 35 to engage and move the cam 13 and, consequently, the pawl 20 to engage the ratchet 21. A spring detent 36 prevents rotation of the shaft 14 except under the positive action of the striker 35. Thereafter, the shutter can be raised by rotation of the hand wheel 26, and is held at any desired position by the engagement of the pawl 20 with the ratchet 21. The connection between the pawl 20 and shaft 14 allows the pawl to ride over the ratchet during rewinding. The ratchet is loose on the shaft 22, and is locked to it, when rewinding of the shutter is desired, by means of a sleeve 23 and thread 27 on the shaft.

Title: Method for extracting and separating alcohols in organic media
Inventor: RADZITZKY PIERRE
IPC: B01J39/04
Filed: 1957-10-09
Abstract: An alcohol is selectively separated from an organic medium containing at least one alcohol by selectively absorbing the alcohol in an anhydrous cationic ion exchange resin, the selectivity of which for the absorbed alcohol is obtained by variation of the degree of cross linking, and desorbing the alcohol after separation of the resin from the organic medium. The preferred resins are sulphonated polystyrene resins crosslinked by divinyl benzene in the acid form.  The process may be used, for example, for the extraction of alcohols from the products of the oxo synthesis or for the extraction of alcohols from a mixture obtained in the production of esters when excess alcohol is used.  The alcohols absorbed by the resin may be desorbed by heating the resin under vacuum or by displacement of the alcohol by an alcohol which is more strongly absorbed, e.g. methyl alcohol.

Title: Improvements in vacuum apparatus for raising liquids
IPC: F02M37/02
Filed: 1923-12-17
Abstract: 208,704. Guichard, L. Dec. 20, 1922, [Convention date]. Vacuum apparatus.- Apparatus for raising liquid', such as fuel for internal - combustion engines, comprises a chamber 1 connected to atmosphere by a port 6 and to a source of suction by a passage 7 and a pipe 4. A perforated tube 11 carries a valve 13 controlling the suction and atmospheric ports, and a valve 14 controlling ports 8 through which the liquid flows from the chamber 1 to a feed chamber 2. As the liquid rises in the chamber 1 during a suction period, a float 9 rises and lifts the tube and valves by engaging a stop 15 on the tube. The chamber 1 is then connected to atmosphere and the suction is cut off, and at the same time the valve 14 is raised to open the ports 8 and allow discharge of the liquid into the chamber 2. During discharge the upper face of the valve 13 is exposed to suction, so that the valve remains in the raised position until the liquid level has fallen so low that the weight of the float resting on the stop 16 overcomes the suction pull and returns the valves and tube to the position shown in the Figure.

Title: Air temperature control system for a room having an outside wall
IPC: F24F7/04
Filed: 1976-09-29
Abstract: Present in the device is a framework which is flowed through by a heat transport fluid, consists of hollow uprights (1 - 3) and hollow crosspieces (4, 7) and on which the facade elements are suspended virtually without heat or cold bridges. A convector pipe (11), which is provided in an air supply duct (15) with a lateral air-outlet slot (16), can be connected into the heat-transport fluid circuit thermostatically. According to the mode of operation of the device, the framework consisting of hollow uprights and hollow crosspieces and the convector pipe is supplied with hot or cold water, by which air circulating in the space formed by the framework and in said air supply duct is heated or cooled. The hollow-upright and hollow-crosspiece framework acts in this case as a slowly responding base-load system, while the convector pipe works as a rapidly responding regulating system. As a result of the low volume of the pipes with a relatively large surface, a rapid heating or cooling of the air is achieved with a high efficiency. <IMAGE>

Title: Punched record tape verifying method and apparatus
Inventor: BIHALY LAJOS
Filed: 1957-10-11
Abstract: 874,889. Verifying punched tapes. INDUSTRIAL ACCOUNTANCY PARTNERSHIP Ltd. Jan. 12, 1959 [Oct. 11, 1957], No. 31830/57. Class 106 (1). In a method of verifying a punched tape record and simultaneously producing a corrected punched tape a tape punched by a first operator in accordance with his reading of a set of instructions is fed past a sensing device responsive to the tape punchings in step with the feed of a second tape past a second punching device actuated by keys operated by a second operator in accordance with his reading of the same set of instructions, and the second punching device is so controlled by the sensing device that the second tape is only punched if the keys operated by the second operator correspond to the punchings of the first tape, while a discrepancy prevents such punching and interrupts the feed of the tapes. As described, the two tapes are constituted by two strips or fields 21, 22, Fig. 10, of a wide tape. The first operator punches data into the lower field 21 in a " 1, 2, 4, 8 " binary code, adjacent hole positions being slightly staggered. This data is then read and each digit correspondingly positions four notched bars, one being shown in Fig. 17, the notches being such that for each combination of displacements of the four bars only one column of notches is in line. These bars, 10, 11, 12, 13, Fig. 7, are so disposed in relation to the keys 14, 15 operated by the second operator that every key is prevented from being depressed except that key corresponding to the digit actually sensed from the tape. Thus, unless the key struck by the second operator corresponds to the digit already punched in the tape by the first operator it cannot be depressed. If the struck key does correspond, it is depressed and it causes punching, in the conventional punch card code, of the appropriate digit in the upper field 22, Fig. 10, of the tape.
