Title: Improvements in and relating to hydraulic pressure shock absorbers
IPC: F16F9/06
Filed: 1953-05-05
Abstract: 740,920. Hydropneumatic shock absorbers. BOURCIER DE CARBON, C. May 5, 1953 [May 5, 1952], No. 12531/53. Class 108 (3). In a shock absorber (which does not function also as a suspension device) comprising a cylinder C containing liquid L and a gaseous volume A separated by means P, and a double-acting piston P<SP>1</SP> having passages x, y controlled by automatic, oppositely - acting valves c, d, the pressure of the gas under static conditions of the shock absorber is equal to, or higher than 5 atmospheres. The means P comprises a plastic or metal piston having a rubber packing disc E retained by a metal disc D. Alternatively, the piston P may be made wholly of rubber, or it may be formed as a disc of cork or sponge rubber (Fig. 3, not shown). An air-filling valve b may be obviated by the following method of assembly: The piston p is inserted in the cylinder, and forced down to the closed end until sufficient pressure is generated. The air so trapped may include a few fragments of solid carbon dioxide or any other suitable liquefied or solidified gas. The cylinder is inverted and filled with liquid and sealed at J. Instead of a closure V for the valve b, the end of the passage a may be soldered over. Where the travel of the piston is greater than the corresponding relative movement of the parts between which the shock absorber operates, by a factor x, the operative pressure of the liquid should be at least 5 x. In the case of a heavy vehicle, the pressure should be 2M atmospheres (M is the weight of the vehicle in metric tons). U.S.A. Specification 2,410,176 is referred to.

Title: Memory circuit
IPC: G11C11/414
Filed: 1971-04-30
Abstract: 1293711 Transistor data storage NATIONAL CASH REGISTER CO 30 April 1971 [30 April 1970] 12548/71 Heading H3T [Also in Division G4] In a matrix memory (see Division G4) comprising an array of transistor bi-stables each column of which has two associated column lines a number of row/column address decoders are provided, the arrangement being that when the memory is on standby current flows through each cell into one or its associated column lines in accordance with the stored datum and in a selection operation the current flowing through all the non-selected cells in the column in which the selected cell lies is directed away from the column lines, the current in a selected cell remaining in the appropriate column line. As described each cell comprises two crosscoupled double emitter transistors, one pair of emitters being connected to respective column lines and the other pair to single row line. The selection decoders comprise a multiple emitter transistor, the emitters of which are connected to selected bit positions in an address register and the base of which is connected to an enabling pulse source V z . During standby periods the emitters e 2  and e 4  of each cell are held at a relatively high potential and the emitters e 1 , e 3  at a relatively low potential. When a particular cell is selected by the row and column decoders and on the occurance of an enable signal V z  the base emitter junctions of the selected multi-emitter decode transistors, say Q1 and Q39 will be reverse biased turning on transistors Q2 and Q40, saturating Q3 and Q41, and switching Q4 and Q42 off thereby keeping the select lines X o  and Y o  and hence emitters e 2  and e 4  at a relatively high potential. The remaining decoders, e.g. row X n  and column Y m  will have their multi emitter transistors Q5 and Q43 saturated, transistors Q6, Q7 and Q44, Q45 switched off and transistors Q8 and Q46 saturated so that their select lines X n  and Y m  will be held at a relatively low potential (as shown substantially ground). Each column is provided with a combined sense amplifier /write network, Fig. 3 (not shown), which is appropriately switched in accordance with the polarity of a Read/write signal on the occurance of the enable signal V z . The column select decoders may be omitted if required and a complete word written into or read from a selected row of cells in parallel. Alternatively a single row could be used to store two words, one of two sense amplifier/ write networks being selected according to which word is to be read/written. The whole system is formed on an integrated circuit using LSI techniques.

Abstract: A modified homopolymer of an alpha-monoolefine or a modified copolymer thereof with either at least one other polymerizable monomer containing the CH2=C< radical or carbon monoxide is produced by heating said homo- or copolymer having a molecular weight of at least 10,000 with a modifying agent which is an organic carboxylic acid or an acid anhydride or acid ester derived therefrom at a temperature from 225 DEG C. to 400 DEG C. under autogenous pressure for 0.5 to 10 minutes.  The modifying agent may be a saturated or unsaturated aliphatic monocarboxylic acid having from 2 to 6 or 3 to 6 carbon atoms respectively, e.g. acetic, propionic, butyric, valeric, caproic, acrylic, crotonic and sorbic acids or an anhydride or ester of such acids, the alkyl esters having from 1 to 6 carbon atoms in the alkyl chain.  Unsaturated aliphatic dicarboxylic acids having from 4 to 8 carbon atoms may also be used e.g. maleic, tetrahydrophthalic, fumaric, glutaconic and itaconic acids or their anhydrides or alkyl esters having from 1 to 6 carbon atoms in the alkyl chain. Phthalic anhydride or pyromellitic anhydride may be used.  Copolymerizable monomers mentioned are butene-1, propylene, ethyl acrylate, vinyl acetate, methylmethacrylate, divinyl ether, acrylic acid and bicyclo [2.2.1]-2-heptene.  The amount of modifying agent is preferably from 0.25 to 10% by weight based on the combined weight of polymer and modifying agent.  The homo- or copolymer and modifying agent may be blended in an extruder and then passed into a reaction zone or the reaction may be carried out in the extruder; alternatively the molten modifying agent or a solution of the modifying agent may be added to the molten polymer as it leaves the extruder. The modified polyolefines may be cured by heating from 50 DEG  to 180 DEG C. to produce cross-linked polymers.  Modified polyethylene produced by the invention may be vulcanized, for example, by heating 100 parts of the resin with 40 parts of PbO and 3 parts of mercaptobenzothiazole at 150 DEG C. and 250 p.s.i.a. for 30 minutes; or plaques of it may be dyed or it may be used to coat steel, paper, "Cellophane" and "Mylar".
