Title: Amine salts of isethionic acid and derivatives thereof
Inventor: HENDERSON JAMES IAN
Filed: 1962-03-21
Abstract: Primary or secondary aliphatic or aromatic amine salts of isethionic acid or a methyl substituted derivative thereof are prepared by reacting ethylene oxide or propylene oxide with a bisulphite salt of the said amine.  The reaction is preferably effected at 100 DEG  C. and at substantially atmospheric pressure in an atmosphere of an inert gas.  Amine salts prepared by the above process may be reacted with an alkali or alkaline earth metal hydroxide or alkali metal carbonate to produce alkali or alkaline earth metal salts of alkylamino- or arylamino-alkylsulphonic acids.  This further reaction is preferably effected at 150 DEG  to 300 DEG  C. in an atmosphere of inert gas and in the presence of a primary or secondary aliphatic or aromatic amine which may be the same as or different from the amine present as the salt reactant; two different amines will, however, yield two aminoalkylsulphonic acid products.

Title: Improvements in or relating to glassware washing machines
IPC: A47L15/00
Filed: 1949-04-26
Abstract: 666,428. Cleaning drinking glasses. LOFSTRAND, A. R. April 26, 1949, No. 11121/49. Class 138 (i). [Also in Groups XXIV and XXXII] A glassware washing machine includes a counter-balancing structure comprising a carriage movable on an upwardly extending hollow support, a spirally grooved pulley rotatably mounted above the support and a flexible cable connected at one end to the carriage and extending around the pulley into the support and connected at its other end to a member slidable in the support, wherein a spring is disposed between the member and a fixed part of the support and wherein that part of the cable between the pulley and the carriage engages the pulley at a point further from the axis of the pulley than that part of the cable extending between the pulley and the slidable member. An elevator structure 51 is movably supported relative to horizontally movable carrier 26 supported above a tub 15 by rollers 35 engaging in tracks 28. The elevator 51 is attached to a vertically movable carriage 60 having rollers 62 which engage in vertical grooves formed in a tubular vertical elevator supporting post 64, so that tumblers 57 in a wire basket 56 carried by the elevator may be lowered into the tub 15. In order to counterbalance the elevator a flexible cable 78 connected thereto at 75 passes over a spiral grooved pulley 79 supported on top of the post 64, passes through an opening 83 and is connected to a member 84 slidable within the post 64. The member 84 is constantly urged downwardly by a spring 85 positioned between the member and a cap 67'secured to the upper end of the post, which spring surrounds the cable 78. The movement of the cable 78 along the spiral groove of the .pulley is from the larger diameter to the smaller diameter as the elevator is lowered by operating a handle 90, so that, the rate of change of spring compression decreases with further downward movement of the elevator thereby providing a nearly constant force on the cable 78 and the counterbalancing effect of the spring is practically constant for all positions of the elevator. Initial movement of the handle 90 depresses a brush carrier 86 slidably mounted on the elevator and the carrier is held depressed by a bar 110 provided with ratchet teeth engaging a latch plate 123 in the manner described in the Specification 666,427. Specification 666,429,. [Group XXIV], also is referred to.

Title: A method of measurement of physical magnitudes
Inventor: DUFTSCHMID KLAUS E
IPC: G01G9/00
Filed: 1966-03-15
Abstract: 1,145,562. Photo-electric measuring. OSTERREICHISCHE STUDIENGESELLSCHAFT FUR ATOMENERGIE G.m.b.H. March 15, 1966 [March 19, 1965(2)], No.11275/66. Heading G1A. Measurement of physical characteristics such as thickness, weight per unit area, density, absorption &c. of materials, particularly individual sheets, is carried out by transmitting radiation through the material 9 to a detector 2 and obtaining a pulse count in a predetermined time, then substituting for the material a comparison absorption member 3, and obtaining a measure of the time for the same pulse count to be registered as before, the time measured being used to obtain the required value for the material. The method can be applied to investigating plastics or glass sheets (for thickness or weight/area). In typical apparatus an Ru 106 source and plastics scintillator detector, are used but an X-ray tube source can be used. The circuit includes a programme control unit 4, counter 5, timer 6, oscillator 7 supplying time pulses to the timer and a timer display 8 which may be digital or linear. The circuit is detailed in Fig.2 (not shown). The measurement of a physical characteristic of the material is carried out in two stages. Initially, the plastics comparison chamber 3 is in the radiation path. The introduction of the material 9 tobe tested changes the count rate and this change is detected by a control unit 4 so that the absorber 3 is ejected. After a predetermined delay to allow the required portion of the material to enter the radiation path, the counter 5 is actuated to count pulses from the detector, at the same time the timer 6 counting pulses from an oscillator 7. The time of counting of the timer is predetermined and is related to the comparison absorber thickness as determined in previous measurements and on attaining this time, the timer causes stopping of the counter 5. The comparison absorber is then moved back into the radiation path and the material 9 is removed. The change in counting rate is sensed and as a result the count stored in counter 5 inverted so that the number stored is its full capacity minus the value counted in the first measurement. After a delay, the counter 5 is restarted. As the counter counts, the timer counts pulses from the oscillator, displaying the count continuously on a numerical digital display. When the counter 5 reaches its full capacity it stops the timer 6, whose final display value is the required measurement and is proportional to the physical quantity of interest. The oscillator frequency can be adjusted by means of a feedback from the indicator so that the value indicated is a required function (e.g. linear) of the physical quantity actually measured. It can be arranged that the display gives the actual value of the physical quantity of interest.
