Abstract: A simple preschool assembly toy for young children which comprises at least three relatively large parts that are assembled together by the child to provide a representation of a recognizable object such as a toy vehicle and driver. A first and a second part are positioned adjacent to one another and include mechanically inter-engaging elements which limits relative movement between these parts only in a first direction, while allowing them to be separated in a second direction generally transverse to the first direction. A third part is positionable adjacent to the other parts, and second inter-engaging elements are provided on the third part and one of the other parts to limit relative movement between the parts in the second direction. The second inter-engaging elements may be engaged and disengaged by motion only in the second direction; as for example by the provision of magnets.

Abstract: An interlocking panel and panel track system which includes at least one frame having a plurality of upright members with first and second end portions, a first and second connector plate member engaging the upright members at the first and second end portions, respectively, the first and second connector plate members each including a flange portion and a notched portion and a plurality of projecting members connected to the upright members and cooperatively engaged with at least one of the first and second connector plate members. A method of assembling the wall panel includes cooperatively connecting at least one of the first and second connector plate members to one end portion of the upright members so as to engage the plurality of projecting members and cooperatively engage the flange portion of the first frame with the notched portion of the second frame and with at least one of the plurality of projecting members so as to interconnect the first and second frame.

Abstract: A plurality of fire, smoke, security or other detectors of the type which respond to the existence of a predetermined condition are each connected to an input circuit. Each input circuit is connected to one indicator circuit and when a detector is triggered, the input circuit associated with that detector generates a signal which in turn actuates and latches on the corresponding indicator circuit. The indicator circuit remains latched on even after the detector returns to an untriggered condition and the input circuit signal is removed. A first release circuit is provided to release all indicator circuits which have been latched on. When a predetermined number of detectors simultaneously respond to their respective predetermined conditions, an alarm signal generates an input to by-pass the first release circuit, thus precluding the first release circuit from releasing the plurality of indicator circuits.

Abstract: To facilitate determination of the refractive-index profile of an optical fiber by the near-field technique, the fiber to be examined is inserted into a body of transparent liquid held by surface tension in a surrounding capillary tube also made of light-transmissive material. The tube, which is axially coextensive with the inserted fiber, has a refractive index less than the minimum index of the fiber core and cladding whereas the liquid has a refractive index exceeding the maximum index of the fiber core.

Abstract: A method for manufacturing modulated disc records (i.e. video or audio records) including bonding a plastics material foil to the unmodulated face of a stamper plate before the stamper plate is secured between the rams of the record press. This method obviates the necessity for backsanding the stamper plate, as hitherto adopted procedure which was time consuming, unreliable and often hazardous.

Abstract: Vegetable proteins may be converted into isolates which are useful for preparing imitation cheese products. These unique isolates are characterized in general as: having an NSI of at least 90, having not been subjected to enzymatic or chemical hydrolysis, forming an insoluble gel when reconstituted in water at a 15% by weight protein isolate concentration and heated to 85.degree. C. for 30 minutes, and yielding a melt value of at least 15 cm.sup.2. The isolates are prepared under conditions which precondition the protein molecules so that they may be converted, upon heat treatment, into protein aggregates which simulate the hydrocolloidal attributes of caseinate. The heat treatment causes restructuring of the proteinaceous molecules into large molecular weight aggregates.

Abstract: A nutritious vegetable seed solubles binder for animal feed blocks. The subject vegetable seed solubles contain about 80% by weight carbohydrate and up to about 24% by weight protein on a dry substance basis. The new binder may be used as a complete or partial replacement for cane molasses as a binder in animal feed blocks, including those such as molasses/salt blocks, medicated feed blocks and high protein feed blocks. The subject vegetable seed solubles may also be combined with soybean hulls, bagasse or such similar material to make an ingredient which is then used to make animal feed blocks.

Abstract: A hose cleaning plant comprises an elongated horizontal receptacle (10) in which a number of hoses (16) may be placed side by side in extended positions, washing equipment (13) provided at one end of the receptacle (10), and a transport device (18) which is movable along the receptacle to draw a hose (16) through the washing equipment and along the receptacle (10), above the same. In order to make it possible, upon completion of a washing operation on a hose (16), to have the hose laid down in proper position in the receptacle (10) without considerable manual efforts, said transport device is formed by a carriage (18) which is supported on rails (19), provided adjacent to the longitudinal upper edges of the receptacle (10), and which is provided with means (20) for releasably holding an end portion of a hose (16) in a selected position in the transversal direction of the receptacle (10).

Abstract: The reaction of a polyfluorocarbonyl compound such as a polyfluoroketone or polyfluorocarboxylic acid fluoride with fluoride ion and a polyfluoroallyl chloride, bromide or fluorosulfate produces a polyfluoroallyloxy compound, e.g., CF.sub.2 .dbd.CFCF.sub.2 OCF.sub.2 CF.sub.2 SO.sub.2 F. The polyfluoroallyloxy compounds copolymerize with ethylenically unsaturated monomers such as tetrafluoroethylene, chlorotrifluoroethylene or vinylidene fluoride to form polymers which are moldable, and in some cases electrically conducting or are water-wettable and dyeable.

A digital complex multiplier (32) is responsive to the product signals and to the output of a number controlled oscillator (34) to produce a digital output corresponding to the data signals. The output of the number controlled oscillator (34) is controlled by a digital phase lock loop.

Abstract: An electro-mechanical pulse generator for producing electronic pulses to set or correct the readout of an electronic digital display. Two contact assemblies rotatable relative to one another cooperate to close at least two pairs of electric contact elements to produce at least two pulses. The pulses have a phase shift relative to one another which is dependent upon the direction of relative rotation of the contact assemblies and a frequency which is proportional to the speed of rotation. Control logic determines the phase shift of one pulse relative to another, i.e. lead or lag, and causes an UP-DOWN counter to produce an up-count or down-count accordingly.
