Title: Method and apparatus for processing chocolate and the like
IPC: A23G3/22
Filed: 1958-12-22
Abstract: 891,788. Coating bakers' and confectioners' goods; tempering chocolate. SOLLICH, R. Dec. 22, 1958 [Feb. 25, 1958], No. 41274/58. Classes 28 (1) and 129. Excess tempered chocolate is fed to an enrober, moulding-machine or the like and the surplus c is fed back and divided into two portions d and e, portion e being mixed with a constantly replenished stock b of untempered chocolate of which a portion a is mixed with portion d, the mixture being tempered and then used. In the enrobing machine shown, the delivery device 8 is arranged over an endless openwork belt 10 beneath which is a supply tank 1 and an adjacent through-pass container 2 which intercepts part of the chocolate d and supplies it to mixing chamber 3. The remaining chocolate passes to tank 1 and thence to temperature raising chamber 4 separated from tank 1 by a heating jacket 11 and containing a worm or like conveyer 12 working in a narrow gap and preferably with interrupted threads. This chocolate is then fed to mixing chamber 3, any surplus passing back to tank 1 through pipe 9 which also allows air and vapour bubbles to escape. Feeding elements 5 and 6 feed the chocolate respectively from chamber 4 and container 2 to chamber 3 in selected proportions. A paddle 14 is movable in tank 1 which is trough-shaped. From chamber 3 the chocolate passes to cooler 7, where it is tempered, through pipe 15 and thence to delivery device 8. Chocolate dripping off band 10 beyond the edges of containers 1 and 2 is caught and guided into these containers by plates 16. All the apparatus is at least partly enclosed by jackets containing a heating medium to regulate the temperature. A travelling strainer 17 carried on pulleys above tank 1 and container 2 catches foreign bodies, e.g. cake crumbs and sugar crystals, and feeds them to a worm conveyer 19 parallel to pulley 18. Specification 891,787 is referred to.

A spring closing mechanism for a circuitbreaker comprises one or more helical springs 5 for closing the breaker and an hydraulic jack for charging the springs arranged concentrically within the said springs. Liquid is pumped into the jack cylinder 19 through a pipe 22 from a reservoir 24, a microswitch 41 automatically controlling a motor 40 in the pump circuit to keep the springs 5 fully charged. Stops 47 retain the springs 5 fully charged until released electrically by a solenoid 42 or manually by a lever 53, the consequent movement of a lever 45 causing opening of a pilot valve 23, which in turn opens the main valve (Fig. 2, not shown) allowing rapid discharge of the liquid in the jack cylinder 19. As springs 5 extend, a push rod 14 closes the circuit-breaker by a trip-free mechanism 31 and the motor 40 is automatically started to recharge the springs. An auxiliary hand-operated jack (not shown) may be used for slow closing of the breaker.

Title: Phenol-formaldehyde resinous composition
IPC: C08G8/28
Filed: 1959-12-08
Abstract: Silica sand is coated with a liquid composition of a modified phenol aldehyde or phenol-ligninaldehyde resin, wax and hexamethylene tetramine, by the hot mulling process, and used to make shell moulds. The resins (see Division C3) are modified by incorporation of one or more of rosin, copal, shellac, or a coumarone and/or indene resin, during their manufacture.ALSO:In a liquid composition containing by weight 65-85% resin solids, 7-12% free phenol and 4-8% water, the resin solids conprise (1) An A-stage phenol-formaldehyde or phenol-lignin formaldehyde condensate with which additional methylol groups have been introduced, and (11) a modifier which is one or more of rosin, copal shellac, and a coumarone and/or indene resin; the amount of lignin not exceeding 50% of the lignin plus phenol; the amount of resinous modifier being not more than 30%, and the amount of lignin plus resin modifier being not more than 50% of phenol plus resin plus lignin.  The compositions are particularly useful for coating sand to be used in shell moulding.  Part of the resin modifier may be reacted with the phenolaldehyde or phenol-lignin-aldehyde condensate during the introduction of extra methylol groups in the initial condensate. The lignin is used in finely divided powder form.  Hexamethylene-tetramine is added to the compositions as a curing agent and wax as a lubricant. The compositions may be thinned if necessary with an alcohol or ketone. In examples (1) phenol is condensed with formaldehyde at a pH of 1 and a temperature not exceeding 70 DEG C.; the pH is adjusted to 7, further formalin added and condensation continued at 80 DEG C. During this second stage rosin is mixed in. The resinous product is washed and water distilled in vacuo to yield a product with 83-85% resin solids, 10-11% phenol and 5-6% water. (2) A coumarone resin is used in place of rosin, and methanol is added to the final composition. (3) Lignin is included in the initial phenol-aldehyde condensation, and rosin is used as modifier. (4) is similar to (3) using a coumarone resin as modifier and with addition of methanol to the final composition. The products of the above examples were mixed with sand, hexamethylene tetramine and wax and used to form shell moulds the hot and cold strengths of which were measured and compared with those of moulds from an ordinary phenol-formaldehyde resin.

Patent GB-886131-A (GB)
Title: A process for the preparation of unsaturated esters and alcohols
IPC: C07C69/527
Filed: 1959-12-24
Abstract: Unsaturated esters and unsaturated alcohols are prepared by condensing an aliphatic aldehyde containing a <FORM:0886131/IV (b)/1> group under substantially anhydrous conditions in the presence of an aluminium alcoholate, stopping the reaction at a point at which the products of the reaction are substantially only monomeric, recovering the resulting unsaturated ester and recovering the unsaturated alcohol after hydrolysing the corresponding alcoholate formed in the reaction mixture.  The aluminium alcoholates may be derived from primary, secondary or tertiary alcohols, and there are specified many aliphatic alcohols and aralkyl alcohols, e.g. benzyl and phenyl isopropyl alcohol.  The alcoholates may be simple or mixed alcoholates and are preferably used in amounts of 0.001 to 0.05 moles per mole of aldehyde.  Condensation is normally effected at 0 DEG C.-65 DEG C. in the presence, if desired, of a solvent, e.g. an ether, halogenated hydrocarbon or an aromatic hydrocarbon.  Reaction may be terminated at the required point either by decomposing the catalyst, for example, by addition of water, or by rapidly distilling off the resulting unsaturated ester, unchanged aldehyde and ketone or aldehyde-by-products, if desired, with an azeotrope former, leaving aluminium alcoholate as residue which is then hydrolysed to liberate the unsaturated alcohol product.  In examples (1) acrolein is condensed yielding allyl acrylate and allyl alcohol, the catalyst being tri-(sec.-butoxy or iso propoxy) aluminium and (2) methacrolein is condensed yielding methallyl methacrylate and methallyl alcohol using tri(methallyloxy) aluminium as catalyst; in all cases the end-point for the condensation is determined gas-chromatographically and reaction is stopped by flash-distillation followed by treating the residue with aqueous NaOH.  Unchanged aldehyde may be recycled. Specifications 532,054 and 663,425 are referred to.
