Title: Method for removal of unreacted monomer from synthesized high molecular weight polymer latex
IPC: C08F6/00
Filed: 1975-07-18
Abstract: 1494249 Removal of unreacted monomer from polymer latex KUREHA KAGAKU KOGYO KK 18 July 1975 [19 July 1974] 30275/75 Headings C3P and C3G [Also in Division B1] Unreacted monomer is removed from polymer latex by rotating a hollow cylinder inclined at a gradient of 1/100 to 1/10 to the horizontal around its longitudinal axis, introducing the polymer latex downwardly into the interior of the cylinder at the higher end thereof and, at the same time, delivering a gas containing moisture into the interior of said cylinder via either end thereof whilst continuing to rotate the cylinder, thereby bringing said gas and latex into contact, and withdrawing said gas containing unreacted monomer from the cylinder. A suitable arrangement of apparatus is shown in Fig. 1 in which latex enters cylinder 1 via inlet 5 and is discharged through a port in the cylinder (not shown) and through pipe 7. Similarly the gas is introduced via inlet 6 and exhausted via pipe 8. The cylinder may be provided with a solid concentric cylindrical core which thus defines an annular space, or with one or more concentric cylinders in its interior with a solid core in the innermost, thus defining a series of annular spaces, the gas and latex being passed through this (these) space(s). In the examples, the gas used is steam, but air or nitrogen, saturated with moisture, are also specified. Specific latices treated are of acrylonitrile/methyl acrylate copolymer, vinyl chloride/vinylidene chloride copolymer and butadiene/methyl methacrylate/ styrene graft copolymer.

Title: Improved process for the preservation of milk
IPC: A23C3/03
Filed: 1929-10-05
Abstract: Milk is preserved by heating it to 70-90 DEG  C., homogenizing it at this temperature, and then subjecting it to two or more pasteurizations with an interval or intervals between of sufficient duration and under suitable conditions for development of any spores present.  The homogenization is effected at 150 atmospheres pressure or over and may be followed by a second homogenization at a lower pressure, e.g. 75 atmospheres.  The homogenization may be at lower pressures, down to 25 atmospheres, providing it is repeated.  The pasteurization may be carried out by heating the milk to 67 DEG  C. or over for an hour, then keeping it at 40 DEG  C. for a day, and again heating it to 67 DEG  C. for an hour. Where a long preservation is desired, the milk is again kept for a day at 40 DEG  C. and then heated as before.  The temperature of 40 DEG  C. is, in a modified form, maintained only for about 4-5 hours, the milk being left at room temperature for the remainder of the period.

Title: Method of determining the strength of glued joints
IPC: G01N3/06
Filed: 1964-07-31
Abstract: 1,065,014. Testing glued joints. A. K TOKAREV. July 31, 1964, No. 30295/64. Heading G1N. The strength of a glued joint is determined by measuring its resistivity and comparing it with a curve of strength versus resistivity prepared from a series of glued samples. The figure shows four bare wire electrodes 1 in a glued seam. An A. C. is applied between the outer pair and the current measured at A while the voltage is measured between an inner pair of electrodes at V. A  correction may be made for the difference in location of the voltage and current electrodes although the same pair of electrodes may be used for both instruments. Resistivity versus solidification curves are plotted by means of electrodes in the walls of a liquid glue container for the liquid phase of the glue, and by pairs of electrodes at the ends and an intermediate pair in a solid glue sample for the solid phase.

Filed: 1974-07-16
Abstract: 1469305 Power steering ROBERT BOSCH GmbH 16 July 1974 [17 July 1973] 31381/74 Heading B7H In an hydraulic servo steering system comprising a control valve 1 having a spool 3 operated in response to actuation of a steering wheel (not shown) to control pressure supply to servomotor 70, the pressure also acting on the spool end faces 29, 33 to act as a restoring force, a device 46 is provided for interrupting the pressure supply from the control valve to the servomotor and simultaneously connects an accumulator 37 to the servomotor in response to the working pressure reaching a predetermined value. As shown in Fig. 1 on deflection of the steering wheel, spool 3 is moved to the left by lever 7 therefore pressure supply from line 15 flows through connecting bore 28, chamber 30, line 43, and via grooves 60, 66 of the control device 46 and line 68 to the working chamber 69 of servo 70. The righthand chamber 73 of the servo is connected to the right-hand reaction chamber 34 by line 72, annular grooves 66<SP>1</SP>, 60<SP>1</SP>, and line 44. Chamber 34 is then connected to return line 21 by connecting bore 32 and annular grooves 26, 18, and passage 20. Movement of spool 3 to the right causes operation of the servo in a similar manner to the above. When a predetermined working pressure is reached, e.g. during high resistance at the wheels at slow speeds, the end face of spool 48 of device 46 is subjected to the pressure via passage 62, and port 63 in spring abutment plate 51, and spool 48 is displaced against the force of initially stressed spring 52, whereby annular groove 60 is closed and communication is established between the accumulator 37 and working chamber 69 via line 59, central annular grooves 58, 66 and line 68. Similar communication may be established between the accumulator and working chamber 73. In a modification, Fig. 2 (not shown), a pressure reducing valve limits the pressure supplied from accumulator 37 to the control valve 1.
