Abstract: 1,054,533. Photopolymerizing acrylic esters. GENERAL MOTORS CORPORATION. June 10, 1965 [June 25, 1964], No. 24543/65. Heading C3P. Esters of acrylic or methacrylic acid with alcohols containing 1 to 18 carbon atoms are polymerized by subjecting the ester, together with triphenyl phosphine as photoinitiator, to U.V. radiation within the range of 1849 to 4000 Angstroms. Alcohols from which the esters are derived include alkanols, 2-(dimethylamino)- ethyl alcohol, 2 - (t - butylamino) - ethyl alcohol, glycidyl alcohol, 2-methoxyethyl alcohol, 2-hydroxyethyl alcohol and hydroxypropyl alcohols. Polymerization may be effected in bulk or in a solvent, e.g. benzene, or with the polymerizable composition in the form of a coating on a substrate. Examples illustrate the polymerization of glycidyl methacrylate, 2- methoxyethyl methacrylate, 2 - (t - butylamino)-ethyl methacrylate, methyl methacrylate, methylacrylate, lauryl acrylate, stearyl methacrylate and isobutyl methacrylate.

A surface grinding machine for use with peripheral grinding wheels 31, 31a has two grinding carriages 19, each of which is adapted to support a respective peripheral grinding wheel such that the axes of the wheels are mutually perpendicular and each of which is movable in two mutually perpendicular directions for feeding, in operation, a grinding wheel mounted thereon, in a first direction axially of the grinding wheel and in a second direction perpendicular to the first direction.  As described the carriages 19 are slidable vertically in guideways provided in respective slide members 18 which are slidably mounted for horizontal movement with respective guideways 15a in support members 15 and 21. The workpieces are supported on an inclined surface portion of a longitudinally reciprocable table 2 having dressing devices 20 adjacent one end. In one method of operation the wheels 31, 31a are dressed by devices 20 and the workpiece placed on the table 2. A pass of the table 2 is effected and automatic redressing occurs before the return pass is made. In a second method, the wheels are withdrawn, the workpiece positioned on the table 2 and the table reciprocated'whilst the wheels are advanced by hand wheels 7 until sparking occurs. The wheels are subsequently advanced intermittently at the end of each double pass of the table 2 by a pawl-and-ratchet mechanism until the hand wheels 7 indicate a preset size on a scale and cause a cam switch to be operated. The wheels are then dressed, a double pass effected, a second dressing performed and a single fine-dressing pass made.

In a gas ignition safety device, shown in its "off" position and comprising an ignition safety valve 16 and a main valve 17 disposed in a housing 10 having a gas inlet 11, a control knob 30 and rod 31 must be rotated and depressed, Fig. 4 (not shown), to open valve 16 for ignition of a pilot burner, then raised by a spring 35 and further rotated in the same direction and moved outwards again, Fig. 7 (not shown) to open the valve 17 for a main burner, and is characterized in that when the knob 30 is in its " off " position a stop bar 42, slidably and non- rotatably secured on the end of rod 31 remote from the knob, is urged by a spring 43 to engage slots (45) in a guide rail 46 between the valves to prevent rotation of the knob, Fig. 10 (not shown) unless the closure member 19 of valve 16 is shut, when a cup 47 secured thereto raises the bar 42 out of the slots. In use, the valve 16 is held open by an electromagnet 24 supplied with current from a thermocouple at the pilot burner flame. The closure member 29 of valve 17 is slidable on rod 31 and a collar 37 on the rod serves to lift the member open as well as providing an abutment for spring 43, a collar 44 on the rod simultaneously lifting the bar 42. Return springs 35, 36, 27 act to urge the knob outwards and the valves 17 and 16 shut respectively.

Jan.29, 1969 [Jan. 30, 1968, Jan.20, 1969], No.4962/69. Heading G1A.  The length of a solid or semi-solid moving object e.g. a bar 2 emerging from a rolling mill 1, is measured by timing the passage of the front end of the object past detectors in a downstream group of detectors which are relatively widely spaced apart in the direction of travel, and of the rear end of the object past a number of detectors in an upstream group which are more closely spaced, storing the time measurements and using a computer to perform various calculations to determine the length. The distance between the first and last detectors of the upstream group corresponds to the largest interval separating two consecutive sectors of the downstream group. The computer operations involve calculation of the mean speeds of movement over the spacings of the upstream group, and the acceleration or deceleration if any, of the rear end of the bar past detectors in the upstream group, and a decision as to which method of calculation to employ, depending on which detector of the upstream group the rear end of the bar is nearest to when the front end passes a particular detector in the downstream group. The temperature of the bar may be measured so that any corrections required due to temperature variations may be carried out on the length measurement which is used to control cutting up of the bars from the rolling mill output.

Abstract: 1,264,572. Numerical displays. SONY CORP. 3 April, 1970 [3 April, 1969], No. 15971/70. Heading G4H. In a display system comprising a plurality of indicator tubes 1a-1e each having a first electrode 2 and a plurality of second electrodes 3a-3j and 4a-4e the first electrodes being energized sequentially and the second electrodes being interconnected in groups of corresponding ones, the groups being selectively energized in synchronism with the energization of the first electrodes, means are provided for energizing one of the point electrodes 4a-4e on a reduced duty cycle so that the corresponding electrode glows less brightly and may thereby be used as a place indication and distinguished from the decimal point. The point electrodes are positioned at the right hand side of each tube. One of these is selected to indicate the decimal point by switch SW1. The fixed contacts are connected to leads 14a to 14e which are sequentially energized to select the tubes in turn. The switch SW1 is turned to engage contact 23b connected to lead 14b, connected in turn to tube 1d. When this tube is selected, therefore, the point electrode 4d is illuminated. Ganged to switch SW1 is a similar switch SW2. The fixed contacts of this switch are also connected to leads 14a-14e but in the order 14d, 14e, 14a, 14b, 14c so that switch SW2 selects a lead displaced by 3 leads from that selected by switch SW1. The place is therefore indicated by a point electrode in tube 1a displaced by three tubes from the decimal point. The place point electrode is energized from the wiper of switch SW2 through a scale-of-three counter 28 so that it is only illuminated once in three cycles. The place electrode therefore flows less brightly than the decimal point electrode and may thereby be distinguished from it. The system may also be used to dim or extinguish selected digit electrodes e.g. those below the decimal point. Specification 1,133,181 is referred to.
