Filed: 1935-11-12
Abstract: 463,740. Charging batteries. CHANCE BROS. & CO., Ltd., and HALLETT, L. B. H. Nov. 12, 1935, No. 31252. [Class 38 (iv)] Systems in which two or more dynamos driven from a common prime mover each charge a battery, are so controlled that each battery when fully charged is supplied at a reduced charging rate while the prime mover is stopped when all the batteries are charged. The dynamos Gl, G2 charge batteries J1, J2 respectively, each dynamo having a shunt field pf, pf2 in series with resistances r, r2 which are short - circuited during normal charging by switches e2, h2. On closing temporarily pushbutton switch ps, relay A is energized from battery J1 and operates (1) switches a6, a3, so that both batteries supply current to the dynamos for starting an engine ; (2) switch a2 whereby fuel and choke relays sv, sc and voltage responsive relay D are operated ; (3) switch a1 providing a holding circuit for relay A ; and (4) switch a4 operating voltage responsive relay F. Should the engine not start promptly, thermal relay C opens switch c1 and de-energizes relay A thus cutting off the supply of current to the dynamos. When battery J1 becomes fully charged before the other, voltage relay D closes contact d<1> whereby relay E is energized and in turn closes maintaining switch e1, opens switch e3 and switch e2 thus inserting resistance r in field circuit of dynamo G1 and reducing the charging rate. Similarly, when battery J2 is fully charged first, voltage relay F operates switch S1 in-circuit of relay H whereby switches h1, h2, h3 are operated. When both batteries are charged, switches e3 and h3 are both closed so that relay A is de-energized and the engine driving the dynamos is stopped. Specification 430,791 is referred to.

Filed: 1975-07-25
Abstract: 1496914 Selective printing ADDMASTER CORP 25 July 1975 [25 July 1974] 31263/75 Heading B6F Compensation for the thickness of a record medium located between a type character and a platen 37 is achieved by a yieldable drive which moves the character and platen together to engage the record medium and a positive drive to effect impression. As shown only the platen 37 is moved. A drive from a motor to shaft 46 is transmitted to a friction clutch 52 and onward through gears 55, 63 to rotate eccentrics 60, 66 until the platen holds the record medium (31) against type wheels (11), Fig. 1 (not shown); thereafter clutch 52 slips. Simultaneously the drive to shaft 41 is transmitted via gears 67, 68, 70 to rotate eccentrics 40 and thereby impress the record medium against the type wheels. Following impression the eccentrics 40 rotate on to their starting position. However the eccentrics 60, 66 are self-locking and have to be withdrawn by a reverse rotation of the shaft 51 effected by the partially toothed gears 71, 50 coming into engagement. Line spacing, which can be of variable increments, is controlled by an electromagnet (98), Fig. 14 (not shown), which when pulsed steps a gear 80 so that gear 76 driving paper rolls (33), Fig. 1 (not shown) is rotated towards the end of the impression cycle. To permit viewing of the printing line, gear 75 (with only three teeth) engages the gear 76 to reverse feed the paper by three lines early in the printing cycle and towards the end of the cycle three lines of forward feed is produced by three toothed gear 77 engaging gear 76 via gear 78.

Title: Process for the production of 2-methyl-1-butene
IPC: C07F5/06
Filed: 1958-10-03
Abstract: 2-Methyl-1-butene is produced by a process involving (1) reacting propene with triethyl aluminium to give mixtures of hydrocarbons including 2-methyl-1-butene which is recovered and mixtures of aluminium trialkyls, and (2) reacting the aluminium trialkyls in the presence of a nickel hydrogenation catalyst to produce aluminium triethyl which is recycled to the first step and a hydrocarbon mixture including 2-methyl-1-butene which is recovered.  Propene and ethylene also recovered from the hydrocarbon mixtures are recycled to the first and second steps respectively.  The first step is operated with excess propene, e.g. 3-6 mols. per mol. of aluminium triethyl at 100-250 DEG  C. and 110-500 atmospheres.  The second step may be effected using excess ethylene at 50-150 DEG  C. and 20-150 atmospheres; suitable catalysts are finely divided nickel or Raney nickel or other metal or metal salt which adsorbs ethylene; the presence of this catalyst does not affect the first stage and the catalyst may therefore be present in both stages.

Patent GB-655237-A (GB)
Title: Improvements in the preparation of glycol and glycerol and their esters
IPC: C07C29/159
Filed: 1948-12-09
Abstract: Glycol, glycerol, and their esters are prepared by heating carbon monoxide with hydrogen at above 150 DEG  C. and above 1,500 atmos., preferably at 180-300 DEG  C. and 2,000-5,000 atmos. Formate esters are generally formed in addition to the free polyhydric alcohols.  In the presence of water, ethylene glycol and formates thereof are formed selectively.  Acetic acid directs the reaction to the formation of glycerol and glyceryl acetates. Other esterifying reactants may be present to produce esters of the polyhydric alcohol. Reaction may be in vapour or liquid phase.  Inert diluents such as hydrocarbons, alcohols, and esters, or reactive solvents such as formic, acetic, propionic, stearic, and benzoic acids, and phthalic, acetic, and benzoic anhydrides may be present.  Polyhydric alcohol esters, e.g. glycol formates or acetates, may be used as reaction media.  Hydrogenation catalysts, especially those forming carbonyls, may be present: Ni, Cu, Co, Cr, Mn, and Ru, as metals or their compounds, alone or on supports, are specified.  Compounds of cobalt, especially those soluble in the reaction mixture, e.g. the acetate, naphthenate, carbonyl, carbonyl hydride or complexes, and inorganic salts are particularly suitable.  Amounts may be about 0.001 to 20 per cent by weight of the reaction mixture.  The ratio CO : H2 may be from 10 : 1 to 1 : 3, preferably 2 : 1 to 1 : 1.  Mixtures of CO2 and H2 or of CO or CO2 and steam may be used, and metal carbonyls may supply the CO.  Unreacted gas may be recycled, after separation of products, preferably with make-up reactants.  Heat evolved may be absorbed by effecting a simultaneous endothermic reaction.  In examples: (1) to (3) CO and H2 are heated at 3,000 atmos. in presence of acetic acid containing cobalt acetate yielding ethylene glycol diacetate and glycerol triacetate with lower boiling esters; (4) to (7) water containing cobalt acetate, manganese naphthenate, copper zinc chromite, tin acetate, lead acetate, zinc oxide, antimony trioxide, manganese chromite or chromium carbonyl is the reaction medium, pressures vary from 1,800 to 3,000 atmos., and the products are mainly ethylene glycol and its formates.
