Abstract: FLUID PRESSURE BRAKING SYSTEM    ABSTRACT OF THE DISCLOSURE A fluid pressure braking system for an articulated vehicle includes a pair of manually operated, push-pull control valves and a pressure differential responsive dual supply valve,  The inlet of one of the manually operated valves is connected to the fluid pressure source, and the outlet is connected to the parking brakes on the power portion of the articulated vehicle and also to one inlet or the dual supply valve.  Another inlet of the dual supply valve is connected directly to the fluid pressure source.  The outlet of the dual supply valve is connected to the inlet of the second manually operated control valve, the outlet of which is connected to the parking brakes on the towed or nonpowered portion of the articulated vehicle.  Application of the spring brakes on both portions of the vehicle is effected by actuation of one of the valves, but release of the spring brakes on both portions of the vehicle requires actuation of both of the manually operated valves.

Abstract: Plewes, J.T. 8 METHOD FOR MAKING FINE-GRAINED      CU-NI-SN ALLOYS            Abstract of the Disclosure The invention relates to a method for the pro-duction of a fine-grained structure in a Cu-Ni-Sn alloy by a thermal treatment which calls for maintaining the alloy at three specified distinct temperature levels for specified time periods and includes partial homo-genization of the alloy at a specific temperature and for a specific period of time, relatively fast cooling, aging at another specific temperature and at another specific period of time, complete homogenization at a third specific temperature and for a third specific period of time and relatively fast cooling of the body.  The resulting fine-grained alloy may undergo further process-ing as may be beneficial, e.g., to develop desired levels of strength and ductility.

Abstract: ABSTRACT     An ingot mould having at its head a recess extending around the whole of the inner side and a cast iron ( or steel ) collar supported in the recess on the shoulder formed by the recess, the collar having an inner surface substantially aligned with that of the mould and an outer surface spaced from the recessed mould surface which space is filled with a thermally insulting material e.g. Kaowool.  'Hot top' moulds in accordance with this invention posses significant advantages in so far as the head assembly may last the life of the mould, but in any event substantial savings accrue because the conventional heat insulating tiles consumed with every ingot are not employed.

Granted: 1981-09-22
Abstract: ABSTRACT          A method and apparatus for the rapid and continuous formation of reinforced flat bottom bags from a substantially endless roll of gussetted tubing.  The gussetted tubing or sleeve has opposed faces and sides gussetted inwardly be-tween the opposed faces.  The bag is made by closing one end of the sleeve with a seam to seal the opposed faces together with the gussetted sides therebetween.  A mandrel positioned within the sleeve is operated through the sleeve by means exterior to the sleeve.  The mandrel is provided with wing-like members which open the gussetted sides when operated by the exterior means to flatten the gussetted sides against the opposed faces to form flaps of the gussetted sides that have folds lying in overlapping relationship with the opposed faces.  Finally, preselected portions of the flaps in the overlapping sides and faces are secured together to form a flat bottom by pressing the preselected portions of the flaps and the overlaying sides and faces together at the preselect-ed portions and heat sealing to secure the same together.

Abstract: ABSTRACT     A process for preparing peroxide-based bleach media and concentrated bleach compositons for use in carrying out the process, the process comprising incorporating in an aqueous medium a peroxide-based bleach and an activator therefor.     In order to provide a bleach medium which is effective at temperatures at which home laundering is conventionally carried out the activator so incorporated is a cyanoamino and the medium is maintained alkaline, if necessary by the incorporation of a buffering agent.  The cyanoaminos are those of equivalent weight 44 to 600 which have the molecular formula:       , in which R1 and R2 represent hydrogen or Group 1A metal atoms (with certain provisos) or certain hydrocarbyl, alkanoyl, ethoxylate, or proproxylate, cyanoamino or poly-alkenylamino groups or in which R1 and R2 taken together with the amino nitrogen atom to which they are attached form either (a) a 4 to 6 carbon atom-containing ring of 5 to 7 atoms which contains hetero atoms selected from O, S and N-R3, in which R3 can be a hydrogen atom or certain hydrocarbyl, alkanoyl or cyano groups or another hetero-cyclic ring of 5 to 7 atoms, and which defined substi-tuents may optionally be present in one or more of the heterocyclic ring carbon atoms.     The bleach and the activator can be incorporated in the aqueous medium separately or in the form of a liquid or solid concentrated bleach composition.

Abstract: ADAPTIVE DELTA MODULATION SYSTEM     Abstract of the Invention An adaptive delta modulation system is disclosed which features an improved digital compandor which may be used with a digital integrating network.  The compandor executes a commanding algorithm having a nonlinear characteristic to provide a rapid increase in step size to follow the fast rise and start or fast decaying end of talkspurts input signals so as to minimize any slope overload distortions and to provide a small increase or decrease in step size during the smooth portion of the talkspurts in input signals to reduce any granular noise effect.  The step size generated by the compandor is directly related to the input signal level, providing a maximum companding range in which good signal-to-noise characteristics are preserved for the soft or low voiced speaker as well as for the loud voiced speaker and providing a fast transient response most suitable for telephone applications.  The step size logic of the compandor has a built-in minimum step size circuit which insures that a well behaved idle pattern of alternating ones and zeros will appear at the digital output when the input signal is zero, and which provides a mechanism to rapidly build up the step size when an input signal appears.  The step sizes can be integrated with an integrating network to reconstruct the input signal.  The compandor may be used in conjunction with a digital integrating network which exhibits, for example, a system function, having either a single pole or a zero and a pair of poles which may be real or complex.  The filter constants can be chosen to match any input spectrum to obtain optimum performance.  A significantly high signal-to-noise ratio and a wide companding range have been obtained with the disclosed compandor.  By providing storage elements in the compandor and in a digital integrating network and storing the calculated intermediate values, a plurality of input and output analog signals can be time division multiplexed and delta modulated with a single delta modulation system.
