Abstract: 858,524. Rolling. MANNESMANN-MEER A.G. Aug. 1, 1958 [Sept. 16, 1957], No. 24881/58. Class 83 (4). [Also in Group XXIX] An hydraulic motor c for feeding and rotating equipment of Pilger rolling mills and which is operated intermittently has its exhaust liquid constantly determined by a braking device l which cuts off the exhaust when the motor has reached a desired position. A single-plunger pump d has its piston reciprocated by a cam g on a driving shaft f, and during a forward stroke supplies liquid through a non-return valve o to the motor c. Liquid exhausted from the motor passes through a valve m to the cylinder of the braking device which has a piston k controlled by a cam j on the shaft f. When piston k reaches bottom dead-centre exhaust is stopped, and the pump piston is at top dead-centre. Valve m is then changed over by a cam n on the driving shaft so that during the forward stroke of piston k liquid is supplied through valve m to the pump, and the motor exhaust line is blocked.

Title: Improvements in hardenable mixtures of polyglycidyl ethers
IPC: C08G59/50
Filed: 1955-08-31
Abstract: Polyglycidyl ethers obtained by reacting polyhydric alcohols or phenols with halohydrins are hardened by addition of a diamine having the formula: H2N-A-R-BNHX where A and B are the same or different carbocyclic radicals, e.g. aromatic radicals, preferably phenyl radicals or cycloaliphatic radicals preferably hexyl radicals, and R is a bivalent bridge group, e.g. methylene, ethylene, &c. radicals, or -O-, -S-, -NH-, and -HN-CO-NH-while X is H or an aliphatic radical.  The amino groups may be present in the ortho, meta or para positions. Suitable amines are: p,p - diaminodiphenylmethane, p,p1 - diamino diphenylamine, p,p1 - diaminodiphenylurea, p,p1 - diaminodiphenyl propane, o,o1 - diamino diphenylmethane, p,p1 - diaminodiphenyl sulphide; diaminodicyclohexyl methane, diaminodicyclohexylpropane, diaminodicyclohexylcyclohexylmethane, diaminodicyclohexylamine. Mixtures with other amines and mixtures of diprimary and primary-secondary amines may be used.  The amines may be dissolved in the liquid ethers or in solvents, e.g. ketones, esters, alcohols, glycolethers and chlorinated aromatic hydrocarbons. Small amounts of phenol-aldehyde or urea-formaldehyde resins, amines of high molecular weight, or quaternary ammonia compounds may be added as fluxing agents, e.g. the reaction products of a fatty acid ester of diethyl ethanol amine with dimethyl sulphate. In examples: (1) 32.5 parts p,p1-diaminodiphenylmethane are added to 100 parts of the glycidylether obtained from butane triol and epichlorhydrin; the solution yields hard, clear films and can be used to impregnate glass fabrics.  If 10 per cent of the amine is replaced by dipropylene triamine the hardening time is shortened; (2) an epoxy resin from bis-phenol and epichlorhydrin is dissolved in a mixture of butyl acetate, ethylene glycol monoethyl ether and toluene containing 1.5 per cent nonplasticized urea-formaldehyde resin and 10 per cent diaminodiphenylmethane in glycol ether is added; (3) epoxy resin from 4,41-dehydroxy diphenyl propane and 4,41-diaminodicyclohexyl methane; (4) butane triol triglycedyl ester and 4,41-diaminodiphenyl amine; (5) butane triol triglycidyl ether and 4,41-diaminodiphenyl sulphide; (6) as in (5) using 4,41-diaminodiphenyl urea; (7) as in (5) using 2,21-diaminodiphenyldimethyl methane; (8) as in (5) using 4,41-diamino-3,31-dimethyl diphenyl methane.

Abstract: 1,259,852. Refrigerating; defrosting. EMHART CORP. 16 May, 1969 [17 June, 1968], No. 25091/69. Heading F4H. Defrosting the evaporators in the refrigerating system of an open fronted display case is occasioned by supplying liquid refrigerant at above 32 C. to a first evaporator 10, Fig. 1, without vaporization of the refrigerant therein and supplying the cooled refrigerant to the second evaporator 8 for evaporation therein and then reversing the direction of flow of the refrigerant through both evaporators to defrost the evaporator 8 and vaporize refrigerant in the evaporator 10. The reversal of flow is effected by operation of two-way valves 44, 62, Fig. 2, and a diverting valve 52 to cause liquid refrigerant to flow from a receiver 38 and drier 40 in a compression-condensing refrigerating system to alternate evaporators. This flow is controlled by thermostats 70, 72 and solenoids 74, 76 responsive to the temperature of the liquid refrigerant leaving the evaporator being defrosted. Air flow to the display case is circulated by a blower 12 through alternate compartments 22, 24 in which the respective evaporators 8, 10 are mounted. Dampers 28, 30 which control the flow of air through the compartments are controlled by the solenoids 74, 76 to coincide with operation of the valves 44, 62, 52.

Abstract: 535,654. Operating aircraft undercarriages. SOC. OLAER (SOC. ANON. DE MATERIAL OLEO-PNEUMATIQUE), and MERCIER, J. Sept. 1, 1939, No. 25139. Convention date, Jan. 18. [Class 4] An hydraulic jack for operating the undercarriages of aircraft is provided with a locking device comprising a piston valve actuated by the load on the jack and adapted to stop the flow through the conduits in the discharge direction as long as the load is on, or exceeds a pre-determined value. In the form shown the jack is extended by passing pressure fluid through a conduit 9 connecting the end of the working cylinder 1 by a groove 6 in a piston valve 3. When a predetermined resistance is encountered, the piston valve is moved inwardly against the action of a spring 17 into the position shown, and fluid for further extension of the jack passes through a non-return valve 12 in a byepass 10. The jack can be retracted only when the load upon it is relieved, for example when the weight of an aeroplane is removed from the undercarriage on taking-off. In some cases, the jack operates against tensile forces. In modifications, the piston valve passes into the working cylinder and is subjected to the pressure in the cylinder as well as to that of a spring.
