Title: Process for the production of closed-cell gas-containing cellular bodies
IPC: C08J9/12
Filed: 1953-07-22
Abstract: Closed-cell, gas-containing cellular bodies are made by forming a pasty liquid from a thermoplastic resin or an elastomer, e.g. polyvinyl chloride, or copolymers of vinyl chloride with vinyl acetate or acrylonitrile or both or with acrylic esters, polystyrene, polyacrylic compounds, cellulose acetate, or a mixture of polyvinyl chloride and an acrylonitrile-butadiene polymerizate, bringing the liquid in a shape having a surface contact area several times larger than a sphere of the same mass into contact in a container under pressure, e.g. 30-350 atmospheres, with a difficulty condensable gas, e.g. nitrogen, hydrogen or carbon dioxide, introduced from outside the container, so as to incorporate and distribute the gas uniformly in the liquid, heating before, during or after incorporation of the gas so as to gelatinize any ungelatinized material, cooling, relieving the pressure on the gas-treated material, removing the rudimentary cellular body so produced from the container and expanding it. Conversion of the starting material to the pasty liquid condition may be effected by addition of solvents or plasticizers, or by heating.ALSO:Closed-cell, gas-containing cellular bodies are made by forming a pasty liquid from a natural or artificial rubber or a thermoplastic resin, or a mixture, e.g. polyvinyl chloride with an acrylonitrile-butadiene polymerizate, bringing the liquid in a shape having a surface contact area several times larger than a sphere of the same mass into contact in a container under pressure, e.g. 30-350 atmospheres, with a difficulty condensable gas, e.g. nitrogen, hydrogen or carbon dioxide, introduced from outside the container, so as to uniformly incorporate and distribute the gas in the liquid, heating before, during or after incorporation of the gas, so as to gelatinize any ungelatinized starting material, cooling, relieving the pressure on the gas-treated material, removing the rudimentary cellular body so produced from the container and expanding it. Conversion of the starting material to the pasty liquid condition may be effected by addition of solvents or plasticizers, or by heating. Incorporation of the gas may be effected by rolling the liquid around in a rotary container under pressure of the gas, by stirring, kneading or screw-conveying the liquid in a stationary container under pressure of the gas, or by passing the liquid, more than once if desired, as drops, threads or sheets through a container of the gas under pressure.  The successive treatments may be carried out in one container, or the material may be pumped, screw-conveyed, or expelled by increased pressure of gas from one container to another.

Title: Improvements in or relating to systems for compressing the frequency band of pulse trains
IPC: H04N7/12
Filed: 1957-07-01
Abstract: 862,955. Band-width compression systems. PINTSCH ELECTRO G.m.b.H. July 1, 1957 [June 29, 1956], No. 20763/57. Class 40 (4). In a system for transmitting signals consisting of pulses of varying widths and intervals between the pulses also of varying widths, pulses or intervals having long durations are transmitted with larger average speeds than pulses and intervals of short duration. In one method the signals are stored at a uniform speed on a storage tube and scanned twice in succession by different beams, the first scan determining the duration of the pulse or interval which determination is then used to control the speed of the second scan, the signals therefrom being transmitted. In a preferred method the signals are stored at uniform speed and, at the beginning and end of each pulse, the reading speed is slowed down. This results in the average reading speed being larger for the long pulses or intervals and smaller for the short pulses or intervals. Alternatively the signal can be written in with a beam whose scanning speed is increased at the beginning and end of each pulse, the signal then being read off at uniform speed. In one method of carrying out the first preferred embodiment, Figs. 2 (a), 2 (c), 3, a condenser is charged at the beginning and end of each pulse and allowed to fall away exponentially as shown in Fig. 2 (c). The reciprocal of this function is then formed, the said reciprocal being applied as a control signal to a pentode which charges a condenser. The voltage V across the condenser then varies about a linear rise, as shown by the thick curve of Fig. 3, the slope of the curve, corresponding to the speed of scanning, being reduced at the beginning and end of each pulse. In an alternative circuit, Figs. 6 and 7, for carrying out this method, the signal is fed to a differentiating network 14, Fig. 7, whose output is fed to a cathode follower 15 and a phase inverter 16. The respective outputs are then fed to circuits 17, 18 which give positive pulses in response to negative inputs so that two positive pulses are produced corresponding to the leading and trailing edges of the original pulse. These operate flip-flop circuits 19, 20 (whose restoration time is accurately determined by the incorporation of a delay line) to produce two pulses of predetermined duration which are combined in circuit 21 whose output feeds a circuit 22 which produces a steadily increasing output when the pulses are not applied but a stationary output when the pulses are applied. This voltage, as shown at 11, Fig. 6, is superimposed on steadily rising voltage 13 to produce a scanning voltage 12 of the desired form.

Title: Electronically controlled fuel injection systems
IPC: F02D41/18
Filed: 1975-05-16
Abstract: 1511344 Automatic control of fuel injection ROBERT BOSCH GmbH 16 May 1975 [23 Sept 1974] 20790/75 Heading G3N The effect of transient speed fluctuations which interact with an electronically controlled fuelinjection system to cause jolting in the vehicle is minimized by reducing the charging rate of a first injection pulse duration determining capacitor by providing a second capacitor which is arranged to be included in the charging circuit when the voltage on the first capacitor exceeds that on the second. In the arrangement shown a pulse train 80 derived from the engine contact breaker 30 causes the capacitor Cl to be charged by constant voltage source A over part of an engine revolution T1-T3 and is then discharged by the voltage source E whose constant output voltage is dependent on the air-flow into the engine to produce an injection pulse dependent on the discharge time T3-T4. By the provision of the second capacitor C2, diode D1 and voltage source L, the charging rate is reduced when the voltage on capacitor Cl exceeds that on second capacitor C2 so that charging of Cl now occurs in two parts T1- T2 and T2-T3, Fig. 5, whilst the discharge still occurs over the period T3-T4. In the case where the engine speed changes momentarily Fig. 10 (not shown) the injection pulse duration will charge only very little compared with the charge found with prior systems. The value of capacitor C2 is greater than that of C1.

Title: Improvements in and relating to six-wheeled vehicles
IPC: B60K17/36
Filed: 1925-08-19
Abstract: 264,548. Niblett, H. Aug. 19, 1925. Sprigs, arrangement of; aale attachments; equalizing load on wheels.-Relates to six-wheeled motor vehicles having a bogie comprising twin driving-axles connected together by longitudinal springs pivoted to the vehicle frame. The casings of the driving axles are connected to the frame by parallel or substantially parallel link members pivoted to the frame at separate points so that the torque of the axle-casing is taken by the frame and the torque of the bogie as a whole is resisted without affecting the even distribution of weight on the driving-wheels. As described, the axles are connected together at each end by a pair of parallel springs d pivoted to the frame a at a common point d<1> and constituting one of the link members for each axle. The point d<1> is preferably substantially in a line with the axles. The other link members comprise torque members h, h<1> somewhat inclined as shown, but preferably parallel, to the springs, the points of connection of these members to the frame lying vertically above the axis of the pivots d<1>. The members h, h<1> are preferably connected to the axles and frame by ball or like joints. The springs d are connected to the axles by link members f universally mounted on seatings g which may float, on the axle casings, transversely of the vehicle, the floating movement being limited by collars e' on the casings. The axles may thus undergo angular displacement as shown in Fig. 6 without lateral displacement or distortion of the springs.
