Title: Polyethers containing phosphorus and alcoholic hydroxy groups and their production
IPC: C08G18/50
Filed: 1965-12-13
Abstract: The invention comprises a process for the production of hydroxy-containing ether derivatives of bis (hydroxyalkyl) phosphinic acid in which (i) white phosphorus is reacted with an alkali metal hydroxide, water, and an aliphatic aldehyde in the presence of a liquid saturated aliphatic alcohol; (ii) the more volatile components are distilled off; and (iii) the product, primarily a salt of bis (hydroxyalkyl) phosphinic acid, is reacted with at least one epoxy compound at 50 DEG  to 160 DEG  C., the quantity of the epoxy compound being such as to provide at least 3 mol. per g-atom of phosphorus in the phosphinic acid.  The invention also comprises the product prepared according to step (iii) of the process above using epichloro- or epibromo-hydrin, styrene, propylene or ethylene oxide, or glycidol, as the epoxy compound, and having an hydroxyl number of 60 to 400 and an acid number of 2 to 6, and containing 3 to 12% of phosphorus.  When an epoxy compound other than epichlorohydrin is used, the resulting product may be subsequently reacted with epichlorohydrin. Suitable epoxy compounds are those listed above, while suitable aldehydes are e.g. formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, and their low molecular weight polymers or condensation products e.g. paraformaldehyde, trioxan, and aldol.

Title: Typewriter line space mechanism
IPC: B41J19/84
Filed: 1966-11-28
Abstract: 1,134,771. Typewriters. SCM CORP. 28 Nov., 1966 [26 Nov., 1965], No. 53193/66. Heading B6F. In a typewriter of the kind having a horizontally sliding platen carriage 12, line-spacing actuators are effected by power, e.g. a motor 74, Fig. 2, through a mechanism 32, 34 which provides an accelerating motion during a first portion of the platen line-spacing action and a decelerating motion during the remaining portion of the line-spacing action. The acceleration motion is derived from a crank 32, adjustably secured in relation to a shaft 30 non-rotatively but slidable in a pulley 84. This pulley is driven by a belt 86 and another pulley 72 driven one revolution each time a torsion spring clutch 20 is operated by a latch mechanism (42, 52, Fig. 3) and a power driven shaft 66. The latch is operated by a key from a link 40 or by an arm 174 extending from an actuator 162 operated from a carriage-return key interconnected by a link 160. Long feed; multiple action keys.-A continuous or repeat line-spacing operation may be effected by depressing the line-spacing key beyond the normal single operation depth. When this is done the arm 42 which is pulled by the link 40, causes, by the extra movement, a finger (152) to move a notch (58) clear of the clutch spring end (60) for as many cycles as the key is held depressed. Variable line-spacing.-The crank 32, Fig. 5, is connected to an actuator 34 which has a pin 112 which rests on a cam surface 114 of a variable line-space lever 116. In a threeincrement line space operation the pin immediately drops into a space between the teeth of a ratchet wheel 36 but if two or one increment spacing is required the cam is moved counterclockwise, Fig. 5, and is positioned by a spring detent mechanism 118-120, 122, 124, 126, 128.

Title: A method of producing phosphorus tribromide
Inventor: JENKNER HERBERT
IPC: C01B25/10
Filed: 1966-12-05
Abstract: Phosphorus tribromide is obtained by reacting white phosphorus with bromine, the latter being in an amount 0.05-0.5% above theoretical, at a temperature above 100 DEG  C. in phosphorus tribromide diluent. Either the bromine may be added to a mixture of phosphorus, tribromide and phosphorus, or both reactants may be introduced into the reaction mixture simultaneously but at separate places.

Abstract: 1451360 Measuring exhalation volume of the lungs JUNGNER INSTRUMENT AB 6 Dec 1973 [12 Dec 1972] 56723/73 Heading A5K A device used in conjunction with a lung ventilator to measure the gas volume exhaled by a patient comprises a rigid container 1 divided into first and second compartments 3, 2 by a partition 4, valves 5 and 8 connecting compartment 3 with the respiratory system of the patient and compartment 2 with atmosphere during exhalation, so that the gas volume exhaled by the patient flows into and inflates compartment 3. When exhalation ceases valves 5 and 8 are returned, in response to the control unit of the ventilator, to their opposing positions wherein compartment 3 is connected to atmosphere, and a device 9 is actuated to inject a constant gas flow into compartment 2, a time measuring device 11 being started. Compartment 3 is thus emptied, under the effect of the constant gas flow into compartment 2, through valve 5 to atmosphere. When compartment 3 is completely empty the gas pressure in compartment 2 rises steeply due to gas flow from device 9, this pressure rise being sensed by a pressure transducer 10 in communication with compartment 2 to produce an electrical output signal stopping the time measuring device 11 and returning valve 8 to its other position wherein gas flow from device 9 into compartment 2 is interrupted and compartment 2 is connected to atmosphere. The time interval measured by time measuring device 11 will be directly proportional to the gas volume expelled from compartment 3 and thus to the gas volume exhaled by the patient, and a direct measure of this gas volume is given by multiplying together the time measured by time measuring device 11 and the rate of constant gas flow from device 9. In a second embodiment (Figure 2 - not shown) a smaller constant gas flow is augmented by ambient air drawn in through an ejector (19) to reduce gas consumption of the measuring device. In this embodiment the time interval measured by the time measuring device (22) is directly proportional to the gas volume exhaled by the patient.
