Title: Improvements in and relating to the spring of power-driven vehicles
IPC: B60G15/06
Filed: 1932-01-26
Abstract: 377,900. Spring suspensions; hydraulic shock-absorbers. DAIMLERBENZ AKT.-GES., Untert³rkheim, Stuttgart, Germany. Jan. 26, 1932, No. 2342. Convention date, Feb. 7, 1931. [Classes 108 (ii) and 108 (iii).] In vehicles in which helical suspension springs 5, Fig. 2, and shock absorbers 8 operated by a connection 9 to the axle 3 are provided, the springs are unguided other than by rigid connections between their ends and the axle and frame, and the shock absorber exerts a variable damping force the value of which is zero for upward movements of the axle in the normal position of rest. The axle 3 of each wheel may be pivoted independently to the frame of the vehicle. The hydraulic shock absorber shown in Figs. 4, 4a, 4b, comprises a vertical cylinder 10 with a piston 12, the underside of which is connected through oppositely acting one-way valves 16, 18, with a reservoir formed by the upper part of the casing. When the piston descends, flow of liquid through the passage 20 depends upon the width of the slot 19, 19a in the wall of the piston. Similarly during the upward movement, the rate of flow into the space below the piston depends upon the extent to which the port 22 is uncovered by the slot 21a in the side of the piston.

Title: Method and apparatus for preparing polyisobutylene
IPC: C08F10/00
Filed: 1956-01-25
Abstract: <PICT:0787047/IV (a)/1> <PICT:0787047/IV (a)/2> Polyisobutylene or a copolymer of isobutylene with isoprene or butadiene is recovered from Friedel-Crafts polymerization processes which form a cold suspension of solid polymer particles in a diluent, by discharging the suspension through a nozzle into a plurality of converging streams of steam, to disperse the particles which are then contacted with water to form a dispersion.  In an example, polyisobutylene of high molecular weight, e.g. 200,000 to 500,000, is prepared in a diluent, e.g. methyl chloride or a lower alkane, at -100 DEG  to -160 DEG  F., using as catalyst aluminium chloride in methyl chloride and the suspension discharged through pipe 9 (Fig. 1) into a hot water flash tank 16 containing zinc or sodium stearate as slurrying agent at a pH of 8.5 to 9.5.  Steam is introduced through pipe 11 into a jacket 14 (Fig. 2) around the effluent tube 9, and is directed through nozzles 15 to strike the effluent at converging angles while water is introduced through pipe 13 at a tangent so that the swirl around jacket 12 carries the dispersed polymer and unflashed methyl chloride to drum 16, from which dispersion is withdrawn at 18 (Fig. 1) or recirculated through pipe 13, while vaporized materials are withdrawn at 17 and recycled.

Title: Free flowing, crystalline 2, 3, 4, 6-tetrachlorophenol composition

Abstract: The invention comprises a stable, free-flowing, solid, melt derived complex-crystalline composition containing between 70 and 82.5 per cent by weight of 2 : 3 : 4 : 6-tetrachlorophenol and correspondingly between 30 and 17.5 per cent by weight pentachlorophenol.  The compositions, which preferably contain 80 per cent of the tetrachloro compound, may be prepared by chlorinating phenol in a known manner until the composition, as shown by analysis, e.g. I.R. analysis, is within the desired limits.  The molten product is then solidified and flaked or sub-divided in a known manner.  The compositions may also be prepared by mixing a molten 2,3,4,6 - tetrachlorophenol - pentachlorophenol mixture containing less than 70 or more than 82.5 per cent by weight of tetrachlorophenol with sufficient tetrachlorophenol or pentachlorophenol respectively to bring the product within the desired range of composition and solidifying and subdividing the resulting product.  These compositions are said to retain their free-flowing properties on storage and not to cake. Examples (1) and (4) illustrate the first method of preparation to give products containing respectively 82.5 per cent and 70 per cent of tetrachlorophenol.  Example (3) illustrates the second method by adding pentachlorophenol to a mixture containing 84.3 per cent of the tetrachlorophenol.

Headings H5T and H3W. [Also in Division Gl] A recording apparatus for indicating alternating current voltages, such as may be obtained in electro-cardiographic measurements, comprises an A.C. amplifier 17, at least one coupling capacitor (e.g. 9) in the input stage to the amplifier, an amplifier switch 14 for opening or closing a connection between a reference (earth) and a connecting point between the capacitor and the amplifier, a drive arrangement 60, 63 for traversing a record carrier 62 through a scribing mechanism 18, 18a and two switches 46a, 47a for switching on or off the drive arrangement and for changing its speed. An arrangement is provided for coupling the amplifier switch 14 to the on-off and speed-changing switches such that when any one of these switches is in the "on" position the connection previously referred to between earth and the amplifier input is open. An additional switch 45a is included in this coupling arrangement and operates so as to reverse the position of the amplifier switch 14 set by the on-off and speed-changing switches. The switch 14 is a normal component of electro-cardiographic measuring apparatus and is included in order to discharge the coupling capacitor, whose circuit has a large time constant when switching between different input leads and amplifier channels. The present invention relates to the action of an additional switch which is included to provide de-earthing so that a check may be made as to whether the apparatus is ready for operation and so that the position of the zero line at the recorder may be checked before commencing a recording. In the embodiment described, the amplifier switch is operated by a relay 28 whose operating current is provided from the collector circuit of a transistor 27. When the base of the transistor is connected to earth through the switches 38, 37, 36 operated from 47a, 46a, 45a respectively then the transistor conducts and the relay is operated, so that the earthing connection is made. Pressing the switch 45a will change this condition. Should either of the switches 46a, 47a be operated so that the apparatus is in the " on " condition then contacts 37, 39 or 38 will be set in the opposite direction, the base circuit to the transistor will be broken and the earthing connection will not be made, so that the recording apparatus can function. The relay does not however release immediately since the discharge current of capacitor 34b maintains the transistor conducting for a short period. Pressing the switch 45a restores the base circuit of the transistor 27 so as to operate the relay 28 which operates to complete the amplifier earthing connection.
