Title: A luggage case and a process for making a luggage case shell
Inventor: YOUNESSIAN ELLIOT J
IPC: B29C48/355
Filed: 1991-10-15
Granted: 2000-01-15
Abstract: The inventive process forms a thermoformable preform by pressure laminating a layer of cloth fabric to one face of the thermoplastic substrate, preferably as the substrate is extruded and while still hot from the extrusion process. This fabric/thermoplastic laminated preform can be easily processed in a matched mold press. The fabric should be of a non-stretch type. This non-stretch characteristic, together with its intimate bonding to the thermoplastic substrate, prevents the substrate from thinning in the corner regions. Indeed, because the intimately bonded fabric drags or pulls the substrate from a number of directions as the corner regions are formed, the thermoplastic substrate accumulates and actually thickens in the corner regions, leading to a shell which is remarkably durable and aesthetically pleasing.

Abstract: The invention relates to a self-tunable electromagnetic resonant vibrator which automatically controls its vibration frequency by means of the variation of the supply voltage. According to the invention, the vibrator comprises an oscillating element (2) comprising a mobile armature (Am) and a fixed armature (Af), supplied from the AC network by means of a variable voltage regulator (1), a non-linear inductor (L) and a capacitor ( C), the equivalent circuit operating upon resonance, and a transducer (3) which permanently detects the oscillations of the mobile armature (Am) and provides a signal to be applied to an amplifier (4) which amplifies and transmits the same to a shaper (5) which provides signals to a control block (6) where the real vibrator oscillation frequency is compared with a preset value and, if the two frequencies are different, the control block (6) transmits to the variable voltage regulator (1) certain signals for changing the voltage and eliminating the error while simultaneously displaying the oscillation frequency on a display device (7).

Title: Strain-Hardening Cementitious Composite
Inventor: Shehab Eldin Mohamed Mourad
Filed: 2016-09-25
Abstract: A strain-hardening cementitious composite (SHCC) can include cement, fly ash (FA), dune sand (DS), and polyvinyl alcohol (PV A) fibers. The amount of DS in the SHCC can be at least 25% by weight. The cement can be Type I ordinary Portland cement, conforming to ASTM C 150 specifications. The fly ash can be Class F fly ash (FA). The median particle size of the cement can be 14µm. The median particle size of the FA can be 10µm. Fig. 1A.
