Title: Water-dispersible hop flavours for malt beverages and the like
IPC: C12C3/12
Filed: 1966-02-23
Abstract: A hop composition comprises an isohumulone, from 0 to 30% by weight of water and, as solvent, propylene glycol or glycerine (or both), and has a pH of at least 3, preferably between 3.8 and 7. The composition may additionally include essential oil of hop. The isohumulone, which may have been added in the form of an isomerized hop extract or in a substantially pure state (95%) attained by molecular distillation or by filtration with the aid of diatomaceous earth, preferably amounts to between 5% and 30% by weight of the initial composition.  Before its introduction into a beverage, however, the composition is preferably diluted with water to an isohumulone content of from 0.5 to 5% weight.  The examples disclose compositions containing specified proportions of isohumulone, or dihydro-, tetrahydro- or hexahydro-isohumulone, propylene glycol or glycerine, water, specified alkali and hop oil. One composition had a pH as high as 10.7.  Compositions containig 20% isohumulones and 0.1% essential hop oil may be metered into beer in an amount providing 20 p.p.m. isohumulone and 1.0 p.p.m. of hop oil.  The Specification describes the recovery of hop oil by steam distillation of a hop extract in specified organic solvents and the preparation from the residue of an isomerized hop extract rich in isohumulone, employing specified buffering agents and organic solvents.  The following information is additionally provided: (i) the dihydro-, tetrahydro- and hexahydroisohumulones have a reduced carbonyl group, two hydrogenated ethylene groups, and two hydrogenated ethylene groups and a reduced carbonyl group, respectively; (ii) isohumulone includes the group COCH2 -CH(CH3)2, isoadhumulone includes the group COCH(CH3)- -CH2-CH3, and isocohumulone includes the group COCH(CH3)2; (iii) stored alcoholic solutions of isohumulone produce an apple-like aroma on storage; and (iv) non-ionic emulsifiers such as the polyxyethylene ethers of mixed partial oleic esters of sorbitol anhydrides are not stable in beer and produce an unpalatable aroma.

Title: Telephone exchanges
IPC: H04M3/58
Filed: 1975-02-26
Abstract: 1494136 Automatic exchange systems TELEFONAKTIEBOLAGET L M ERICSSON 26 Feb 1975 [6 March 1974] 8111/75 Heading H4K In an exchange system in which a subscriber makes an enquiry call, e.g. to initiate an interim conversation with a third party, by earthing one of the speech wires La, Lb, e.g. by depressing a key K at his substation TA, this earthing is detected at the exchange by a circuit DA which includes voltage dividers R5, R6 and R3, R4 and a differential amplifier DF. The resistors R3-R6 are chosen so that for on-hook (no current in La, Lb ) and connection-established (equal currents in La, Lb) conditions, the output from DF, Fig. 2 (not shown) is substantially zero. However, on depression of key K the currents in La, Lb become unequal, resulting in a negative output from DF. This output actuates a coupling circuit, which brings about the necessary switching sequences for an enquiry call.

Title: Improvements in or relating to electrical remote control systems for missiles
IPC: F41G7/30
Filed: 1959-03-12
Abstract: 866,698. Projectile fuzes. CONTRAVES A.G. March 12, 1959 [March 12, 1958], No. 8569/59. Class 9(1). A missile G provided with a trailing wire connection D to an electrical control installation L,whereby the trajectory of the missile may be corrected for variations in pitch and yaw, comprises a safety device to prevent arming of the fuze until an arming signal is received from the installation L. Trajectory correc-. tions Mn, My made by an operator are converted by transducers Wn Wy to electric signals En, Ey respectively and conveyed by a device K1 and cable D to a device K2 within the projectile. Device K2 separates the signals and conveys them to transducers Vn, Vy which convert the signals into mechanical forces to adjust the steering mechanism of the projectile. In addition, the installation L comprises a transducer Wa for conveying an arming signal through device K1 and cable D to the device K2 which conveys the signal to a transducer Va. The transducer Va converts the signal into a voltage - Va to operate a transistor Ta which serves as an electronic control switch, the voltage being applied to the base electrode of the transistor. Until an arming signal is received, the transistor is non- conductive and forms an open switch in the circuit of a battery Bt connected to a solenoid Ma. On receipt of the arming signal, the transistor Ta becomes conductive, the solenoid is energized and withdraws a shield Ha leaving the charge HL exposed to the detonator Z1. A cam surface on the shield HL closes a switch As as the shield is withdrawn and, on impact, an inertia mass St moves forward closing a switch Zs to complete the circuit from the battery Bt. Thus the detonator Z1 is fired and ignites the charge HL. Charge HL may be a hollow charge and the missile may be self-propelled. A second detonator Z2 may be arranged in parallel with the detonator Z1, this second detonator being provided to blow off the nose of the shell. Amplifying transistors may be provided for stepping-up the in-put voltage between transducer Va and the transistor Ta.

Abstract: 747,562. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd. Feb. 16, 1954 [March 30, 1953], No. 8698/53. Class 40 (4). Apparatus is provided which produces repeated metering of a connection at the end of each of a number of equal periods of time, in response .to the normal metering signal when the called party answers. Application of the usual positive metering signal (by means not shown) to the P wire (Fig. 1) operates the subscriber's meter (not shown) and also energizes the start relay ST, which locks up. Negative battery is thus connected to the cathode of VI, and the condenser C1 previously charged over back ST discharges through R2. After a time determined by the values of C1 and R2, the valve VI conducts, whereupon relay A operates and applies a further metering signal to the P wire. Relay A also connects negative battery to C1 (which is recharged) and V1 (which is cut off). Relay A then restores and the cycle is repeated until, on termination of the call, relay B releases followed by ST. In a second embodiment, Fig. 2, operation of ST replaces the negative battery normally connected to the striker of cold cathode tube T1 by a connection to an impulsing machine supplying positive impulses. After a time dependent upon the values of C1 and R2 and the make-to-break ratio of the impulses, C1 charges sufficiently to fire T1. Relay A then operates, applies a further metering signal to the P wire, connects the striker of T1 to negative battery, and its cathode to positive battery. Tube T1 is extinguished and relay A restores.
