Abstract: A stretching mechanism of a device for cutting slaughtered poultry, said mechanism being provided with a support surface for the bird, with means to hand the bird by the legs, with means to hold the wings of the bird and with means to hold the trunk on the support surface, said trunk holding means including gripper means which engage the spine of the bird. According to the invention the gripper means consist of a symmetrical centering fork and that the centering fork and the support section are guided movably in two directions relative to each other in a plane, perpendicularly to the support surface, wherein in the operative end position the centering fork engages the spine at the inside of the trunk of the bird.
Abstract: The invention relates to an air-cooled ozone generator of tubular type which has a tubular outer electrode, a tubular dielectric, for instance of glass, arranged inside the outer electrode, and an inner electrode in the form of a metal coating on the inner side of the dielectric. The outer electrode and the dielectric are spaced apart and the resulting intermediate annular gap forms a discharge space in which oxygen is converted to ozone. The ozone generator is operated by means of a low-voltage, high-frequency AC source connected to the electrodes. The outer electrode has cooling flanges, and inside the inner electrode there is provided at least one heat dissipating metal body insertable in the inner electrode and expandable to abutment against the inner electrode. Preferably, the metal body also serves as an electric connection for connecting the inner electrode to the voltage source. The metal body preferably consists of a sheet formed into a cylinder with two inwardly directed flanges.
Abstract: A process for the preparation of soap articles containing dried shapes also formed of soap, comprises the steps of placing on the bottom of a cylindrical frame a supporting base transparent soap which has been cooled to solidification but has not been dried as yet, said base having a height lower than that of said frame; fixedly placing a dried shape(s) of colored soap on said supporting base; pouring in said frame a dough of transparent soap which may or may not be colored, and put into a molten state by heating, followed by cooling thereof to solidification; and removing the thus solidified transparent soap with said supporting base from said frame, followed by drying thereof. Instead of using the base, use may be made of one or plural needles.

Abstract: The invention relates to an improvement in constructions having a controllable previous structure and consisting of modular blocks for carrying out breakwaters, harbor dams and the like. Such blocks are premanufactured by casting a standard mix and include two base elements: a male element having a substantially cylindric shape and a wing arranged substantially at half height of the cylindric body provided with an open cavity arranged to embrace the cylindric element of similar blocks; a substantially female element having two open cavities arranged to embrace the cylindric body of the first blocks for carrying out an enchaining of the first type blocks in the entire construction.
Abstract: Neutral calcium hypochlorite is made by producing and separating out from the mother liquor crystals of dibasic calcium hypochlorite; reacting the dibasic calcium hypochlorite with a solution free of insoluble impurities and containing hypochlorite ions to produce hemibasic calcium hypochlorite crystals; separating the crystals of hemibasic calcium hypochlorite from the mother liquor; and converting the hemibasic calcium hypochlorite crystals into neutral calcium hypochlorite.
Abstract: A longitudinally mounted drive train for an automotive vehicle usable with either a manual transmission or an automatic transmission. A housing encloses a clutch in the manual drive train or a torque converter in the automatic drive train. The housing is fastened, in the manual drive train, directly onto the housing of the manual transmission or, in the automatic drive train, by means of a bearing support housing to the housing of the automatic transmission. The housing can be formed of two parts. In both drive trains a shaft having a differential bevel pinion can be provided to couple the transmission to a differential to permit front wheel drive or four wheel drive. The use of common components for the normal drive train and for the automatic drive train results in greatly reduced production costs and lower parts inventory.
Abstract: In a primary air supply unit of a rotary kiln, an improved method for reducing a primary air rate by providing a high-pressure blower for primary air to inject the primary air from a burner together with fuel. In addition, in order to preheat the primary air and to protect any fragile portions in a clinker box for cooling sintered material from the rotary kiln and for preheating the primary air.
Abstract: The turnover device has a frame structure with U-shaped runners and movable loading forks for gripping the load, preferably pallets. The overall center of gravity of the load and the device is in the vicinity of the center of curvature of the runners. Rollers are provided to enable the device also to be used as a transporting means. One or more casters can be moved into the area within the runners, so that the latter do not impede the 180.degree. turnover.
Abstract: A process of producing a moulding by introducing thermoplastics material into a mould space through gate means having a passageway, which process includes the formation of a sprue in the passageway. A retractable member cuts off the sprue before the material solidifies and closes the passageway at its junction with the mould space, the sprue being subsequently ejected from the passageway of the gate means before the next moulding cycle. A holder provides the gate means and the retractable member which is preferably inclined to the passageway. The gate means may also provide air ejecting means for removing the sprue and may conveniently be bolted onto an otherwise conventional injection moulding machine. The retractable member may incorporate a feed pipe for injecting a fluid into the plastics material.
Abstract: Compounds with the formula: ##STR1## in which R.sub.1 and R.sub.2 represent independently, a linear or branched alkyl, cycloalkyl, phenylalkyl or cycloalkylalkyl group. R.sub.1 and R.sub.2 may also represent an alkenyl or alkynyl group. R.sub.1 and R.sub.2 may also represent a group of the formula --R.sub.3 --Z--R.sub.4 in which R.sub.3 represents an alkylene group, on condition that at least 2 carbon atoms separate the nitrogen atom from the group Z; R.sub.4 represents an alkyl group, and Z an atom of oxygen, sulphur or the group >N--R.sub.5, R.sub.5 representing a hydrogen atom or an alkyl group. R.sub.1 and R.sub.2 may form, with the nitrogen atom to which they are attached, a heterocyclic ring. Ar represents a phenyl, pyridyl or thienyl group, or a substituted phenyl group, A and B representing independently, N or CH--, the group C representing the residue of a benzene or thiophene ring. These compounds can be used as medicaments, in particular, for the various applications of benzodiazepines.

Abstract: The additive for Otto cycle engines according to the present invention consists of a mixture of water, ethanol, methanol and butanol to which is added a determined quantity of a liquid obtained by pressing prickly pear leaves. Added in a small percentage to the fuel, gasoline, LP or methane, this additive prevents the oxidation associated with the use of water and/or alcohols in Otto cycle engines, lowers fuel consumption and allows the use of low octane fuel.
Abstract: An improved inflatable cushion lift assembly for use in a bathtub by a person taking a bath. The lift assembly is positioned on the floor of a bathtub and is connected to the bathtub faucet to inflate the cushion. The cushion may be deflated while a person is sitting thereon to lower a person to the floor of the tub. Furthermore, the cushion may be inflated while the person is sitting on the cushion on the floor of the tub to raise the user upwardly to allow the user to exit the tub easily. The present improvement inhibits undesired movement of the cushion while being used by utilizing a rigid bottom panel and/or rigid top panel. Furthermore, the interior of the cushion may be provided with baffles or the like for dampening water oscillations within the cushion. The cushion, for reasons of stability, may also be tiered or formed in layers such that the cushion inflates or deflates in stages.
