Title: Chlorinated polyethylene foam
IPC: C08J9/14
Filed: 1964-11-24
Abstract: Chlorinated polyethylene containing at least 66% by weight of chlorine, is impregnated with 5-50% of a liquid blowing agent and expanded to a foam plastic.  The impregnation may be carried out below the glass transition temperature of the polymer, by agitation with the blowing agent, preferably with the polymer granular, and at a temperature of 60-150 DEG  C., at a pressure sufficient to keep a substantial proportion of the blowing agent liquid.  Extrusion processes at temperatures above the boiling-point at atmospheric pressure of the blowing agent may be used, the polymer being preferably a viscous melt.  The granular impregnated polymer may also be moulded at temperatures above the boiling-point of the blowing agent and above the softening point of the polymer.  The blowing agent may also be injected direct into the extruder.  Linear polyethylene of density 0.935-0.985 may be used for chlorination to a material whose intrinsic viscosity (o-dichlorobenzene at 100 DEG  C.) may be 0.4-3.5 dl/g. Stabilizers such as those containing 2,6 - bis - (t - butyl) - 4 - methyl - t-phenol, pentaerythritol and epoxy compounds, may be used.  The invention also includes per se predominantly closed-cell foamed products of density 0.016-0.32 g/cm.3, a glass transition temperature at least 100 DEG  C., an intrinsic viscosity in o-dichlorobenzene at 100 DEG  C. of 0.2-5.0 dl/g, and a chlorine content at least 66% by weight.  Blowing agents may be chlorofluoroalkanes such as trichlorofluoromethane which are preferably retained within the closed cells to yield a product of low thermal conductivity, in examples less than 1.2 joule (absolute) hr.-1cm.-1

Patent GB-1316365-A (GB)
Title: Electronic protection device for an automatic power transmission  of a motor vehicle
IPC: F16H61/16
Filed: 1970-10-09
Abstract: 1316365 Change-speed control NISSAN MOTOR CO Ltd 9 Oct 1970 [13 Oct 1969] 48162/70 Heading F2D An electronic protection circuit to prevent unsafe overspeeding of the engine of a motorvehicle provided with an automatic transmission with manual downshift potential, comprises a sensor 14 generating a voltage signal proportional to vehicle speed, a comparator circuit 16 comparing that voltage with fixed voltage levels corresponding respectively to each ratio, and generating signals W1, W2, corresponding to the first and second of the three ratios of the transmission, to indicate that a safe downshift to the particular ratio is possible without causing overspeeding of the engine, and a command circuit 17 responsive to the comparator signals to generate signals applied to the hydraulic control of the transmission to prevent downshift or produce upshift. Only the comparator circuit 16 is described, and this comprises two Schmidt-triggers including six transistors 20 ... 25. The speed sensor 14 generates a negative voltage which increases with vehicle speed increase, is compared with a constant 10-volt positive signal 27, and applied through resistors, adjusted to suit the particular gear ratios, to the bases of first and third transistors 20, 22, causing them to become successively non-conductive with speed increase. Thus over a lowest speed range, safe for first ratio, the first transistor 20 remains conductive, causing the second transistor 21 to be non- conductive so that a safe first speed signal W1 is produced. Above this speed range the first transistor 20 becomes non-conductive, 21 conductive and the safe signal W1 disappears. At the same time the fifth transistor 24 is rendered non-conductive by a connection to the collector of conducting transistor 21, so that a safe second ratio signal W2 is now produced. At 2-3 upshift speed the third transistor 22 is rendered non-conductive the fifth, 24, conductive, cancelling the second-ratio signal W2, whilst the fourth transistor 23 is rendered conductive causing the sixth, 25, to become non- conductive producing a third ratio signal W3. The signals W1, W2, W3 control the hydraulic transmission through the command circuit 17, not described. As an example, at high speed the signal W3 only appears, and if mannal 2 is then selected the signal W3 enforces upshift to or maintains third ratio.

Patent GB-969943-A (GB)
Title: Improvements in or relating to transit-time mass spectrometers
IPC: H01J49/40
Filed: 1962-12-21
Abstract: 969,943. Mass spectrometers. MAXPLANCK-GESELLSCHAFT ZUR FORDERUNG DER WISSENSCHAFTEN e.V., and INSTITUT FUR PLASMAPHYSIK G.m.b.H. Dec. 21, 1962 [Dec. 22, 1961], No. 48501/62. Heading H1D. In a mass spectrometer including a longitudinally extending vacuum tube, the ions produced from a sample to be analysed are caused to oscillate along a portion of the length of the tube; during oscillation the ions become separated into groups in accordance with their charge/mass ratio and these groups are detected a predetermined time after production of the ions. As shown, the vacuum tube of a mass spectrometer contains an arrangement 1 of electrodes having holes on a common axis and connected to a voltage divider and voltage sources so that a trough-shaped, preferably parabolic, potential distribution with a relatively negative minimum point 2a is produced along the tube axis. A pulse generating source 3a is connected to an electron gun system 3 for producing bursts of ions which are accelerated along the axis of the tube. When the ions reach the end of the electrode arrangement 1, they are stopped by the positive potential barrier 9 existing there, and are returned to their production point where they are again reflected by the other positive peak 8 of the potential trough. The ions thus oscillate in the potential trough between the ends of the electrode arrangement 1 and separate into groups in accordance with their charge/mass ratio. At a specific time after production of the ions, a pulse from a source 7 is applied to the end electrode 1a which is thus made more negative. The groups of ions are then able to surmount the lower potential barrier 9<SP>1</SP> for entry into an electron multiplier 5, the output signals from which can be detected and analysed in known manner. The disturbing influence of the electric fields associated with the electron gun system may be reduced by the provision of at least one compensating electrode 3b, e.g. of the iris type, also connected to the pulse source 3a. The detection of the ions may be made by an inductive collector arranged at one end of the tube, or by a signal induced into one of the electrodes in the centre of the electrode arrangement 1. In a second embodiment (Fig. 2, not shown) the electron gun system and the electron multiplier are arranged at the same end of the tube, and the electron beam for producing the ions is injected perpendicularly to the tube axis; also, a shielding electrode situated between the ion source and the electrode arrangement 1 is arranged to be supplied for a short period with a positive potential of such magnitude that the ions created cannot pass into the potential trough. This enables the electron gun system to produce a relatively large number of ions which can be released all together by removing the potential from the shielding electrode, so that the operating time of the ion source can be made relatively long without undesirable widening of the output signal.
